In the Macau Special Administrative Region of the People's Republic of China ("Macau"), the Company owns approximately 72% of Wynn Macau, Limited ("WML"), which includes the operations of the Wynn Macau and Wynn Palace resorts (collectively, the "Macau Operations"). In Las Vegas, Nevada, the Company operates and, with the exception of the retail space described below, owns 100% of Wynn Las Vegas, which it also refers to as its Las Vegas Operations. Macau Operations Wynn Macau features two luxury hotel towers with a total of 1,008 guest rooms and suites, approximately 273,000 square feet of casino space, eight food and beverage outlets, approximately 31,000 square feet of meeting and convention space, approximately 59,000 square feet of retail space, a rotunda show and recreation and leisure facilities. On August 22, 2016, the Company opened Wynn Palace, an integrated resort in the Cotai area of Macau. Wynn Palace features a luxury hotel tower with 1,706 guest rooms, suites and villas, approximately 420,000 square feet of casino space, 11 food and beverage outlets, approximately 37,000 square feet of meeting and convention space, approximately 106,000 square feet of retail space, public attractions, including a performance lake and floral art displays, and recreation and leisure facilities.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company, its majority-owned subsidiaries and entities the Company identifies as a variable interest entity ("VIE") and of which the Company is determined to be the primary beneficiary. For information on the Company's VIEs, see Note 3, "Retail Joint Venture." In April 2016, the Company dissolved its 50% -owned joint venture operating the Ferrari and Maserati automobile dealership inside Wynn Las Vegas, which was closed in October 2015 and accounted for under the equity method. All significant intercompany accounts and transactions have been eliminated. Certain amounts in the consolidated financial statements for the previous years have been reclassified to be consistent with current year presentation. These reclassifications had no effect on the previously reported net income. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid investments with original maturities of three months or less and include both U.S. dollar-denominated and foreign currency-denominated securities. Cash equivalents are carried at cost, which approximates fair value. Cash equivalents of $450.2 million and $1.11 billion as of December 31, 2017 and 2016 , respectively, were invested in bank time deposits, money market funds and commercial paper. In addition, the Company held bank deposits and cash on hand of approximately $2.35 billion and $1.34 billion as of December 31, 2017 and 2016 , respectively. Restricted Cash The Company's restricted cash consists of cash held in trust in accordance with WML's share award plan and additionally as of December 31, 2016, collateral associated with borrowings under a revolving credit facility. Investment Securities Investment securities consist of domestic and foreign short-term and long-term investments in corporate bonds, commercial paper and U.S. government agency bonds reported at fair value, with unrealized gains and losses, net of tax, reported in other comprehensive income (loss). Short-term investments have a maturity date of less than one year and long-term investments are those with a maturity date greater than one year. The Company limits the amount of exposure to any one issuer with the objective of minimizing the potential risk of principal loss. Management determines the appropriate classification of its securities at the time of purchase and reevaluates such designation as of each balance sheet date. Adjustments are made for amortization of premiums and accretion of discounts to maturity computed under the effective interest method. Such amortization is included in interest income together with realized gains and losses and the stated interest on such securities. Accounts Receivable and Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of casino accounts receivable. The Company issues credit in the form of "markers" to approved casino customers following investigations of creditworthiness. As of December 31, 2017 and 2016 , 81.7% and 88.1% , respectively, of the Company's markers were due from customers residing outside the United States, primarily in Asia. Business or economic conditions or other significant events in these countries could affect the collectability of such receivables. Accounts receivable, including casino and hotel receivables, are typically non-interest bearing and are initially recorded at cost. An estimated allowance for doubtful accounts is maintained to reduce the Company's receivables to their carrying amount, which approximates fair value. The allowance estimate reflects specific review of customer accounts and outstanding gaming promoter accounts as well as management's experience with historical and current collection trends and current economic and business conditions. Accounts are written off when management deems them to be uncollectible. Recoveries of accounts previously written off are recorded when received. Receivables, net consisted of the following (in thousands): December 31, 2017 2016 Casino $ 173,664 $ 211,557 Hotel 22,487 21,897 Other 58,577 40,256 254,728 273,710 Less: allowance for doubtful accounts (30,600 ) (54,742 ) $ 224,128 $ 218,968 Inventories Inventories consist of retail merchandise and food and beverage items, which are stated at the lower of cost or market value and certain operating supplies. Cost is determined by the first-in, first-out, weighted average and specific identification methods. Property and Equipment Purchases of property and equipment are stated at cost. Depreciation is provided over the estimated useful lives of the assets using the straight-line method as follows: Estimated Useful Lives (years) Buildings and improvements 10 to 45 Land improvements 10 to 45 Furniture, fixtures and equipment 3 to 20 Leasehold interest in land 25 Airplanes 20 Costs related to improvements are capitalized, while costs of repairs and maintenance are charged to expense as incurred. The cost and accumulated depreciation of property and equipment retired or otherwise disposed of are eliminated from the respective accounts and any resulting gain or loss is included in property charges and other. Capitalized Interest The interest cost associated with major development and construction projects is capitalized and included in the cost of the project. Interest capitalization ceases once a project is substantially complete or no longer undergoing construction activities to prepare it for its intended use. When no debt is specifically identified as being incurred in connection with a construction project, the Company capitalizes interest on amounts expended on the project using the weighted average cost of the Company's outstanding borrowings. Interest of $18.4 million , $94.1 million and $53.3 million was capitalized for the years ended December 31, 2017 , 2016 and 2015 , respectively. Intangible Assets The Company's indefinite-lived intangible assets consist primarily of water rights acquired as part of the original purchase price of the property on which Wynn Las Vegas is located, and trademarks. Indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually. The Company's finite-lived intangible assets consist primarily of its Macau gaming concession and Massachusetts gaming license. Finite-lived intangible assets are amortized over the shorter of their contractual terms or estimated useful lives. Long-Lived Assets Long-lived assets, which are to be held and used, including intangible assets and property and equipment, are periodically reviewed by management for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. If an indicator of impairment exists, the Company compares the estimated future cash flows of the asset, on an undiscounted basis, to the carrying value of the asset. If the undiscounted cash flows exceed the carrying value, no impairment is indicated. If the undiscounted cash flows do not exceed the carrying value, then impairment is measured as the difference between fair value and carrying value, with fair value typically based on a discounted cash flow model. If an asset is still under development, future cash flows include remaining construction costs. Debt Issuance Costs Direct and incremental costs and original issue discounts and premiums incurred in connection with the issuance of long-term debt are deferred and amortized to interest expense using the effective interest method or, if the amounts approximate the effective interest method, on a straight-line basis. Debt issuance costs incurred in connection with the issuance of the Company's revolving credit facilities are presented in noncurrent assets on the Consolidated Balance Sheets. All other debt issuance costs are presented as a direct reduction of long-term debt on the Consolidated Balance Sheets. Approximately $18.7 million , $18.1 million and $16.9 million was amortized to interest expense during the years ended December 31, 2017 , 2016 and 2015 , respectively. Redemption Price Promissory Note The Redemption Price Promissory Note (the "Redemption Note") is recorded at fair value in accordance with applicable accounting guidance. As of December 31, 2017 and 2016, the fair value of the Redemption Note was $1.88 billion and $1.82 billion , respectively. In determining this fair value, the Company estimated the Redemption Note's present value using discounted cash flows with a probability weighted expected return for redemption assumptions and a discount rate, which included time value and non-performance risk adjustments commensurate with the risk of the Redemption Note. Considerations for the redemption assumptions included the stated maturity of the Redemption Note, uncertainty of the related cash flows, as well as potential effects of the following: uncertainties surrounding the potential outcome and timing of pending litigation with Aruze USA, Inc. ("Aruze"), Universal Entertainment Corporation and Mr. Kazuo Okada (collectively, the "Okada Parties") (see Note 14, "Commitments and Contingencies"); the outcome of ongoing investigations of Aruze by the U.S. Attorney's Office, the U.S. Department of Justice and the Nevada Gaming Control Board; and other potential legal and regulatory actions. In addition, in the furtherance of various future business objectives, the Company considered its ability, at its sole option, to prepay the Redemption Note at any time in accordance with its terms without penalty. Accordingly, the Company reasonably determined that the estimated life of the Redemption Note could be less than its contractual life. In determining the appropriate discount rate to be used to calculate the estimated present value, the Company considered the Redemption Note's subordinated position and credit risk relative to all other debt in the Company's capital structure and credit ratings associated with the Company's traded debt. Observable inputs for the risk free rate were based on Federal Reserve rates for U.S. Treasury securities and the credit risk spread was based on a yield curve index of similarly rated debt. Derivative Financial Instruments Derivative financial instruments are used to manage interest rate and foreign currency exposures. These derivative financial instruments include interest rate swaps and foreign currency forward contracts. The fair value of derivative financial instruments is recognized as an asset or liability at each balance sheet date, with changes in fair value affecting net income as the Company's derivative financial instruments do not qualify for hedge accounting. The fair value approximates the amount the Company would pay if these contracts were settled at the respective valuation dates. Fair value is estimated based upon current, and predictions of future, interest rate levels along a yield curve, the remaining duration of the instruments and other market conditions, and therefore, is subject to significant estimation and a high degree of variability and fluctuation between periods. The fair value is adjusted, to reflect the impact of credit ratings of the counterparties or the Company, as applicable. These adjustments resulted in a reduction in the fair values as compared to their settlement values. The Company had three interest rate swap agreements intended to hedge a portion of the underlying interest rate risk on borrowings under our Wynn Macau Credit Facilities, which matured in July 2017. Under two of the swap agreements, the Company paid a fixed interest rate (excluding the applicable interest margin) of 0.73% on notional amounts corresponding to borrowings of HK $3.95 billion (approximately $505.1 million ) incurred under the Wynn Macau Credit Facilities in exchange for receipts on the same amount at a variable interest rate based on the applicable HIBOR at the time of payment. These interest rate swaps fixed the all-in interest rate on such amounts at 2.23% to 2.98% . Under the third swap agreement, the Company paid a fixed interest rate (excluding the applicable interest margin) of 0.68% on notional amounts corresponding to borrowings of $243.8 million incurred under the Wynn Macau Credit Facilities in exchange for receipts on the same amount at a variable rate based on the applicable LIBOR at the time of payment. This interest rate swap fixed the all-in interest rate on such amounts at 2.18% to 2.93% . Revenue Recognition and Promotional Allowances The Company recognizes revenues at the time persuasive evidence of an arrangement exists, the service is provided or the retail goods are sold, prices are fixed or determinable and collection is reasonably assured. Casino revenues are measured by the aggregate net difference between gaming wins and losses, with liabilities recorded as customer deposits for funds deposited by customers before gaming play occurs and for chips in the customer's possession. The commissions rebated directly or indirectly through games promoters to customers, cash discounts, other cash incentives and points earned by customers from the Company's loyalty programs are recorded as a reduction to casino revenues. Rooms, food and beverage, entertainment and other operating revenues are recognized when services are performed or events are held. Entertainment, retail and other revenue includes rental income, which is recognized on a time proportion basis over the lease term. Contingent rental income is recognized when the right to receive such rental income is established according to the lease agreements. Advance deposits on rooms and advance ticket sales are recorded as customer deposits until services are provided to the customer. The retail value of rooms, food and beverage, entertainment and other services provided to guests without charge is included in gross revenues and are then deducted as promotional allowances. The estimated retail value of providing such promotional allowances is as follows (in thousands): Years Ended December 31, 2017 2016 2015 Rooms $ 268,023 $ 211,822 $ 184,779 Food and beverage 164,466 131,479 133,984 Entertainment, retail and other 29,389 26,757 23,975 $ 461,878 $ 370,058 $ 342,738 The estimated cost of providing such promotional allowances, which is included primarily in casino expenses, is as follows (in thousands): Years Ended December 31, 2017 2016 2015 Rooms $ 83,884 $ 63,448 $ 51,775 Food and beverage 143,892 113,341 106,840 Entertainment, retail and other 21,478 17,170 14,414 $ 249,254 $ 193,959 $ 173,029 Customer Loyalty Programs The Company offers loyalty programs at both its Macau Operations and its Las Vegas Operations. Under the program at its Macau Operations, customers earn points based on their level of table games and slots play, which can be redeemed for free play, gifts and complimentary dining and retail shopping. Under the program at its Las Vegas Operations, customers earn points based on their level of slots play, which can be redeemed for free play. The points are recognized as a liability and as a separate element of the gaming transaction with allocation of the consideration received between the points and gaming transaction. The initial recognition of the point liability is at fair value based on points earned multiplied by redemption value, less an estimate for points not expected to be redeemed. The revenue from the points is recognized when redeemed. Gaming Taxes The Company is subject to taxes based on gross gaming revenues in the jurisdictions in which it operates, subject to applicable jurisdictional adjustments, which taxes are recorded as casino expenses in the accompanying Consolidated Statements of Income. These taxes totaled $2.17 billion , $1.32 billion and $1.15 billion for the years ended December 31, 2017 , 2016 and 2015 , respectively. Advertising Costs The Company expenses advertising costs the first time the advertising takes place. Advertising costs incurred in development periods are included in pre-opening costs. Once a project is completed, advertising costs are primarily included in general and administrative expenses. Total advertising costs were $37.8 million , $37.0 million and $25.2 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Pre-Opening Expenses Pre-opening expenses represent personnel, advertising, and other costs incurred prior to the opening of new ventures and are expensed as incurred. During the years ended December 31, 2017 , 2016 and 2015 , the Company incurred pre-opening expenses primarily in connection with the development of Wynn Boston Harbor and Wynn Palace. Income Taxes The Company is subject to income taxes in the U.S. and foreign jurisdictions where it operates. Accounting standards require the recognition of deferred tax assets, net of applicable reserves, and liabilities for the estimated future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on the income tax provision and deferred tax assets and liabilities generally is recognized in the results of operations in the period that includes the enactment date. Accounting standards also require recognition of a future tax benefit to the extent that realization of such benefit is more likely than not; otherwise, a valuation allowance is applied. The Company's income tax returns are subject to examination by the Internal Revenue Service ("IRS") and other tax authorities in the locations where it operates. The Company assesses potentially unfavorable outcomes of such examinations based on accounting standards for uncertain income taxes. The accounting standards prescribe a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. Uncertain tax position accounting standards apply to all tax positions related to income taxes. These accounting standards utilize a two-step approach for evaluating tax positions. If a tax position, based on its technical merits, is deemed more likely than not to be sustained, then the tax benefit is measured as the largest amount of benefit that is more likely than not to be realized upon settlement. As applicable, the Company will recognize accrued penalties and interest related to unrecognized tax benefits in the provision for income taxes. Foreign Currency Gains or losses from foreign currency remeasurements are included in other income (expense) in the accompanying Consolidated Statements of Income. Balance sheet accounts are translated at the exchange rate in effect at each balance sheet date and income statement accounts are translated at the average rate of exchange prevailing during the year. Translation adjustments resulting from this process are charged or credited to other comprehensive income. Comprehensive Income and Accumulated Other Comprehensive Income (Loss) Comprehensive income includes net income and all other non-stockholder changes in equity, or other comprehensive income (loss). Components of the Company's comprehensive income are reported in the accompanying Consolidated Statements of Stockholders' Equity and Consolidated Statements of Comprehensive Income. The balance of accumulated other comprehensive income (loss) consists of currency translation adjustments and net unrealized gains or losses on available-for-sale securities. The following table presents the changes by component, net of tax and noncontrolling interests, in accumulated other comprehensive income (loss) of the Company (in thousands): Foreign Unrealized Accumulated December 31, 2016 $ 2,213 $ (729 ) $ 1,484 Current period other comprehensive loss (2,766 ) (563 ) (3,329 ) December 31, 2017 $ (553 ) $ (1,292 ) $ (1,845 ) Fair Value Measurements The Company measures certain of its financial assets and liabilities, at fair value on a recurring basis pursuant to accounting standards for fair value measurements. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. These accounting standards establish a three-tier fair value hierarchy, which prioritizes the inputs used to measure fair value. These tiers include: • Level 1 - Observable inputs such as quoted prices in active markets. • Level 2 - Inputs other than quoted prices in active markets that are either directly or indirectly observable. • Level 3 - Unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The following table presents assets and liabilities carried at fair value (in thousands): Fair Value Measurements Using: December 31, 2017 Quoted Other Unobservable Assets: Cash equivalents $ 450,230 $ 11,200 $ 439,030 $ — Available-for-sale securities $ 327,455 $ — $ 327,455 $ — Restricted cash $ 2,160 $ — $ 2,160 $ — Liabilities: Redemption Note $ 1,879,058 $ — $ 1,879,058 $ — Fair Value Measurements Using: December 31, 2016 Quoted Other Unobservable Assets: Cash equivalents $ 1,106,606 $ 3,868 $ 1,102,738 $ — Available-for-sale securities $ 301,460 $ — $ 301,460 $ — Restricted cash $ 192,823 $ — $ 192,823 $ — Interest rate swaps $ 1,056 $ — $ 1,056 $ — Liabilities: Redemption Note $ 1,819,359 $ — $ 1,819,359 $ — Earnings Per Share Basic earnings per share ("EPS") is computed by dividing net income attributable to Wynn Resorts by the weighted average number of shares outstanding during the year. Diluted EPS is computed by dividing net income attributable to Wynn Resorts by the weighted average number of common shares outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potential dilutive securities had been issued. Potentially dilutive securities include outstanding stock options and unvested restricted stock. The weighted average number of common and common equivalent shares used in the calculation of basic and diluted EPS consisted of the following (in thousands, except per share amounts): Years Ended December 31, 2017 2016 2015 Numerator: Net income attributable to Wynn Resorts, Limited $ 747,181 $ 241,975 $ 195,290 Denominator: Weighted average common shares outstanding 102,071 101,445 101,163 Potential dilutive effect of stock options and restricted stock 527 410 508 Weighted average common and common equivalent shares outstanding 102,598 101,855 101,671 Net income attributable to Wynn Resorts, Limited per common share, basic $ 7.32 $ 2.39 $ 1.93 Net income attributable to Wynn Resorts, Limited per common share, diluted $ 7.28 $ 2.38 $ 1.92 Anti-dilutive stock options and restricted stock excluded from the calculation of diluted earnings per share 106 758 677 Stock-Based Compensation The Company accounts for stock-based compensation in accordance with accounting standards, which require the compensation cost relating to share-based payment transactions be recognized in the Company's Consolidated Statements of Income. The cost is measured at the grant date, based on the estimated fair value of the award using the Black-Scholes option pricing model for stock options, and based on the closing share price of the Company's stock on the grant date for nonvested share awards. The cost is recognized as an expense on a straight-line basis over the employee's requisite service period (the vesting period of the award). The Company's stock-based employee compensation arrangements are more fully discussed in Note 12, "Stock-Based Compensation." Recently Adopted Accounting Standards In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Compensation - Stock Compensation (Topic 718) , which amends the existing guidance related to the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted the guidance on January 1, 2017 with the following amendments having an impact on its Consolidated Financial Statements: • Accounting for income taxes . Under the new guidance, income tax benefits and deficiencies are recognized as income tax expense or benefit in the income statement and the tax effects of exercised or vested awards are treated as discrete items in the reporting period in which they occur. The amendment was applied prospectively. • Forfeitures. The Company elected to make an accounting policy change to account for forfeitures when they occur. The Company applied the amendment using the modified retrospective transition method, which resulted in a cumulative-effect expense adjustment of $2.7 million , net of tax to retained earnings as of December 31, 2016. The adjustment represents the impact of estimated forfeitures on previously recorded compensation expense as of December 31, 2016 from outstanding stock options and unvested share awards under the previous accounting policy. • Classification of excess tax benefits on the cash flow statement. Under the new guidance, excess tax benefits will be classified along with other income tax cash flows as an operating activity. The amendment was applied prospectively. Accounting Standards Issued But Not Yet Adopted In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows - Restricted Cash (Topic 230), which amends the existing guidance relating to the disclosure of restricted cash and restricted cash equivalents on the statement of cash flows. The ASU requires that amounts generally described as restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The ASU will be effective for the Company on January 1, 2018, with early adoption permitted. The Company will adopt this ASU in the first quarter of 2018 and does not expect a material impact on its Consolidated Statements of Cash Flows. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes - Intra-Entity Transfers of Assets Other than Inventory (Topic 740), which requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs, rather than deferring such recognition until the asset is sold to an outside party. The ASU will be effective for the Company on January 1, 2018, with early adoption permitted. The amendments in the new guidance should be adopted on a retrospective basis. The Company will adopt this ASU in the first quarter of 2018 and does not expect a material impact on its Consolidated Financial Statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments (Topic 230), which clarifies the classification of certain cash receipts and cash payments on the statement of cash flows. In particular, the new guidance clarifies the classification related to several types of cash flows, including items such as debt extinguishment costs and distributions received from equity method investees. The new guidance also provides a three-step approach for classifying cash receipts and payments that have aspects of more than one class of cash flows. The ASU will be effective for the Company on January 1, 2018, with early adoption permitted. The Company will adopt this ASU in the first quarter of 2018 and does not expect a material impact on its Consolidated Statements of Cash Flows. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which amends the existing guidance relating to the definition of a lease, recognition of lease assets and lease liabilities on the balance sheet, and the disclosure of key information about leasing activities. Under the new guidance, lessees will be required to recognize a right-of-use asset and lease liability on the balance sheet, measured on a discounted basis. Operating leases were previously not recognized on the balance sheet. Lessor accounting will remain largely unchanged, other than certain targeted improvements intended to align lessor accounting with the lessee accounting model and with the updated revenue recognition guidance issued in 2014. Lessees and lessors are required to apply a modified retrospective transition approach for leases existing at the beginning of the earliest comparative period presented in the adoption-period financial statements. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. The ASU will be effective for the Company on January 1, 2019, with early adoption permitted. The Company is currently assessing the impact the guidance will have on its Consolidated Financial Statements and related disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 824-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which requires equity investments to be measured at fair value with changes in fair value recognized through net income (other than those accounted for under the equity method of accounting or those that result in consolidation of the investee). The update also requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. This update eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. The ASU will be effective for the Company on January 1, 2018 with early adoption permitted. The Company will adopt this ASU in the first quarter of 2018 and is currently assessing the impact the adoption of this standard will have on its Consolidated Financial Statements. The Company expects a portion of the change in its Redemption Note fair value currently included in the Consolidated Statements of Income will be recorded in Accumulated Other Comprehensive Income (Loss) on its Consolidated Balance Sheet. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing revenue recognition guidance and creates a new topic for Revenue from Contracts with Customers. The new guidance is expected to clarify the principles for revenue recognition and to develop a common revenue standard for GAAP applicable to revenue transactions. This guidance provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. This guidance also provides substantial revision of interim and annual disclosures. The update allows for either full retrospective adoption, meaning the guidance is applied for all periods presented, or modified retrospective adoption, meaning the guidance is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the guidance recognized at the date of initial application. The Company will adopt this ASU in the first quarter of 2018 on a full retrospective basis. The Company continues to assess the impact this ASU will have on its Consolidated Financial Statements. Adoption of this standard will change the presentation of, and accounting for, goods and services pro

Variable Interest Entities [Abstract]
Variable Interest Entity Disclosure	In December 2016, the Company entered into the Retail Joint Venture with Crown to own and operate approximately 88,000 square feet of existing retail space at Wynn Las Vegas. In connection with the transaction, the Company transferred certain assets and liabilities with a net book value of $31.8 million associated with the existing Wynn Las Vegas retail stores from Wynn Las Vegas, LLC, to the Retail Joint Venture. The Company sold Crown a 49.9% ownership interest in the Retail Joint Venture for consideration of $292.0 million , which consisted of $217.0 million in cash and a $75.0 million interest-free note that matured in full on January 3, 2018. As of December 31, 2017 and 2016, the present value of the note was $75.0 million included in prepaid expenses and other and $72.5 million included in other assets, respectively, on the Consolidated Balance Sheets. The cash proceeds will be used to fund future development opportunities and for general corporate purposes. Wynn Las Vegas, LLC transferred all interests as lessor in third-party retail store leases to the Retail Joint Venture as part of the transaction and the majority of the retail stores previously operated by Wynn Las Vegas, LLC are now operated under a master lease agreement between a newly formed retail entity owned by Wynn Resorts, as lessee, and the Retail Joint Venture, as lessor. The Company maintains a 50.1% ownership in the Retail Joint Venture and is the managing member. In November 2017, the Company contributed approximately 74,000 square feet of additional retail space to the Retail Joint Venture, the majority of which is currently under construction at Wynn Las Vegas. The Company expects to open the additional retail space in the second half of 2018. In connection with this transaction, the Company contributed certain assets with a net book value of $25.4 million , consisting primarily of construction in progress for the additional retail space, to the Retail Joint Venture, and received cash of $180.0 million from Crown. The cash proceeds will be used to fund future development opportunities and for general corporate purposes. After this additional transaction, the Company maintains a 50.1% ownership in the Retail Joint Venture and remains the managing member. The Company's responsibilities with respect to the Retail Joint Venture include day-to-day business operations, property management services and a role in the leasing decisions of the retail space. The Company assessed its ownership in the Retail Joint Venture based on consolidation accounting guidance with an evaluation being performed to determine if the Retail Joint Venture is a VIE, if the Company has a variable interest in the Retail Joint Venture and if the Company is the primary beneficiary of the Retail Joint Venture. The primary beneficiary is the party who has the power to direct the activities of a VIE that most significantly impact the entity's economic performance and who has an obligation to absorb losses of the entity or a right to receive benefits from the entity that could potentially be significant to the entity. The Company concluded that the Retail Joint Venture is a VIE and the Company is the primary beneficiary based on its involvement in the leasing activities of the Retail Joint Venture. As a result, the Company consolidates all of the Retail Joint Venture's assets, liabilities and results of operations. The Company will evaluate its primary beneficiary designation on an ongoing basis and will assess the appropriateness of the Retail Joint Venture's VIE status when changes occur. As of December 31, 2017 and 2016, the Retail Joint Venture had total assets of $59.7 million and $33.6 million , respectively, and total liabilities of $0.9 million and $2.1 million , respectively.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Investment Securities Investment securities, available-for-sale consisted of the following (in thousands): Amortized Gross Gross Fair value As of December 31, 2017 Domestic and foreign corporate bonds $ 328,747 $ 6 $ (1,298 ) $ 327,455 As of December 31, 2016 Domestic and foreign corporate bonds $ 245,425 $ 19 $ (720 ) $ 244,724 Commercial paper 56,764 5 (33 ) 56,736 Total $ 302,189 $ 24 $ (753 ) $ 301,460 For investments with unrealized losses as of December 31, 2017 , the Company has determined that (i) it does not have the intent to sell any of these investments, and (ii) it is not likely that the Company will be required to sell these investments prior to the recovery of the amortized cost. Accordingly, the Company has determined that no other-than-temporary impairments exist at the reporting date. The Company obtains pricing information in determining the fair value of its available-for-sale securities from independent pricing vendors. Based on management's inquiries, the pricing vendors use various pricing models consistent with what other market participants would use. The assumptions and inputs used by the pricing vendors are derived from market observable sources including: reported trades, broker/dealer quotes, issuer spreads, benchmark curves, bids, offers and other market-related data. The Company has not made adjustments to such prices.

The borrower is Wynn Resorts (Macau) S.A. ("Wynn Macau SA"), an indirect subsidiary of WML. Wynn Macau SA has the ability to upsize the Wynn Macau Credit Facilities by an additional $1 billion in equivalent senior secured loans upon satisfaction of various conditions. In September 2015, the Wynn Macau Credit Facilities were amended, to, among other things increase the borrowing capacity and extend maturity dates. In connection with the amendment, the Company recorded a loss on extinguishment of debt of $2.1 million . As of December 31, 2017 , the Company had no borrowings under the Wynn Macau Senior Revolving Credit Facility. Borrowings under the Wynn Macau Credit Facilities consist of both United States dollar and Hong Kong dollar tranches and were used to refinance Wynn Macau SA's existing indebtedness and fund the construction and development of Wynn Palace and will be used for general corporate purposes. The Wynn Macau Senior Term Loan Facility is repayable in graduating installments of between 2.50% to 7.33% of the principal amount on a quarterly basis commencing in December 2018, with a final installment of 50% of the principal amount repayable in September 2021. The Wynn Macau Senior Revolving Credit Facility will mature in September 2020, at which time any outstanding borrowings must be repaid. The Wynn Macau Credit Facilities bear interest at LIBOR or HIBOR plus a margin of 1.50% to 2.25% per annum based on Wynn Macau SA's Leverage Ratio (as defined in the Wynn Macau Credit Facilities). As of December 31, 2017 and 2016, the interest rate was 3.16% and 2.76% , respectively. The commitment fee required to be paid for unborrowed amounts under the Wynn Macau Senior Revolving Credit Facility, if any, is between 0.52% and 0.79% , per annum, based on Wynn Macau SA's Leverage Ratio. The annual commitment fee is payable quarterly in arrears and is calculated based on the daily average of the unborrowed amounts. The Wynn Macau Credit Facilities contain a requirement that Wynn Macau SA must make mandatory repayments of indebtedness from specified percentages of excess cash flow. If Wynn Macau SA's Leverage Ratio is greater than 4.5 to 1, then 25% of Excess Cash Flow (as defined in the Wynn Macau Credit Facilities) must be used for prepayment of indebtedness and cancellation of available borrowings under the Wynn Macau Credit Facilities. There is no mandatory prepayment in respect of Excess Cash Flow if Wynn Macau SA's Leverage Ratio is equal to or less than 4.5 to 1. The Wynn Macau Credit Facilities contain customary covenants restricting certain activities including, but not limited to: the incurrence of additional indebtedness, the incurrence or creation of liens on any of its property, sale and leaseback transactions, the ability to dispose of assets, and making loans or other investments. In addition, Wynn Macau SA is required by the financial covenants to maintain a Leverage Ratio of not greater than 5.25 to 1 for the fiscal year ending December 31, 2017, and an Interest Coverage Ratio (as defined in the Wynn Macau Credit Facilities) of not less than 2.00 to 1 at any time.

Borrowings under the Wynn Macau Credit Facilities are not guaranteed by the Company or WML. In connection with the gaming concession contract of Wynn Macau SA, Wynn Macau SA entered into a Bank Guarantee Reimbursement Agreement with Banco Nacional Ultramarino, S.A. ("BNU") for the benefit of the Macau government. This guarantee assures Wynn Macau SA's performance under the casino concession agreement, including the payment of premiums, fines and indemnity for any material failure to perform under the terms of the concession agreement and the payment of any gaming taxes. As of December 31, 2017 , the guarantee was in the amount of 300 million Macau patacas ("MOP") (approximately $37.3 million ) and will remain at such amount until 180 days after the end of the term of the concession agreement in 2022. BNU, as issuer of the guarantee, is currently secured by a second priority security interest in the senior lender collateral package. From and after repayment of all indebtedness under the Wynn Macau Credit Facilities, Wynn Macau SA is obligated to promptly, upon demand by BNU, repay any claim made on the guarantee by the Macau government. BNU is paid an annual fee for the guarantee of MOP 2.3 million (approximately $0.3 million ). WML Finance Revolving Credit Facility The Company's credit facilities include a HK $3.87 billion (approximately $495.2 million ) cash-collateralized revolving credit facility ("WML Finance Credit Facility") under which WML Finance I, Limited, an indirect wholly owned subsidiary of WML, is the borrower.

As of December 31, 2017, the Company had no borrowings under the WML Finance Credit Facility. The WML Finance Credit Facility matures in July 2018, at which time any outstanding borrowings must be repaid. Under terms of the agreement, mandatory repayment is required upon a Change in Control or Material Adverse Effect, as defined in the agreement. 4 7/8% Senior Notes due 2024 and 5 1/2% Senior Notes due 2027 On September 20, 2017, WML issued the $600 million 4 7/8% Senior Notes due 2024 (the "2024 WML Notes") and the $750 million of 5 1/2% Senior Notes due 2027 (the "2027 WML Notes" and together with the 2024 WML Notes, the "WML Notes").

The 2025 Notes also are subject to mandatory redemption requirements imposed by gaming laws and regulations of gaming authorities in Nevada. The 2025 Notes are the Issuers' senior unsecured obligations and rank pari passu in right of payment with the Issuers' 2023 Notes and 2027 WLV Notes. The 2025 Notes are unsecured, except by the first priority pledge by WLVH of its equity interests in Wynn Las Vegas, LLC. Such equity interests in Wynn Las Vegas, LLC also secure the 2023 Notes and 2027 WLV Notes. If Wynn Resorts receives an investment grade rating from one or more ratings agencies, the first priority pledge securing the 2025 Notes will be released.

The 2027 WLV Notes will mature on May 15, 2027 and bear interest at the rate of 5 1/4% per annum. The Issuers may, at their option, redeem the 2027 WLV Notes, in whole or in part, at any time or from time to time prior to their stated maturity. The redemption price for 2027 WLV Notes that are redeemed before February 15, 2027 will be equal to the greater of (a) 100% of the principal amount of the 2027 WLV Notes to be redeemed and (b) a "make-whole" amount described in the 2027 Indenture, plus in either case accrued and unpaid interest, if any, to, but not including, the redemption date. The redemption price for the 2027 WLV Notes that are redeemed on or after February 15, 2027 will be equal to 100% of the principal amount of the 2027 WLV Notes to be redeemed, plus accrued and unpaid interest, if any, to, but not including, the redemption date. In the event of a change of control triggering event, the Issuers will be required to offer to repurchase the 2027 WLV Notes at 101% of the principal amount, plus accrued and unpaid interest, if any, to, but not including, the repurchase date. The 2027 WLV Notes are also subject to mandatory redemption requirements imposed by gaming laws and regulations of gaming authorities in Nevada. The 2027 WLV Notes are the Issuers' senior unsecured obligations and rank pari passu in right of payment with the Issuers' 2023 Notes and 2025 Notes and rank equally in right of payment with the Issuers' guarantee of the Wynn America Credit Facilities, and rank senior in right of payment to all of the Issuers' existing and future subordinated debt. The 2027 WLV Notes are effectively subordinated in right of payment to all of the Issuers' existing and future secured debt (to the extent of the value of the collateral securing such debt), and structurally subordinated to all of the liabilities of any of the Issuers' subsidiaries that do not guarantee the 2027 WLV Notes. The 2027 WLV Notes are unsecured, except for the first priority pledge by WLVH of its equity interests in Wynn Las Vegas, LLC. Such equity interests in Wynn Las Vegas, LLC also secure the 2023 Notes and 2025 Notes. If Wynn Resorts, Limited receives an investment grade rating from one or more ratings agencies, the first priority pledge securing the 2027 WLV Notes will be released. The 2027 WLV Notes are jointly and severally guaranteed by all of the Guarantors. The guarantees are senior unsecured obligations of the Guarantors and rank senior in right of payment to all of their existing and future subordinated debt. The guarantees rank equally in right of payment with all existing and future liabilities of the Guarantors that are not so subordinated and will be effectively subordinated in right of payment to all of such Guarantors' existing and future secured debt (to the extent of the collateral securing such debt). The 2027 Indenture contains covenants limiting the Issuers' and the Guarantors' ability to: create liens on assets to secure debt; enter into sale-leaseback transactions; and merge or consolidate with another company. These covenants are subject to a number of important and significant limitations, qualifications and exceptions. The 2027 Indenture also provides that Wynn America may assume all of Wynn Las Vegas, LLC's obligations under the 2027 Indenture and the 2027 WLV Notes if certain conditions set forth in the 2027 Indenture are met. Events of default under the 2027 Indenture include, among others, the following: default for 30 days in the payment of interest when due on the 2027 WLV Notes; default in payment of the principal, or premium, if any, when due on the 2027 WLV Notes; failure to comply with certain covenants in the 2027 Indenture; and certain events of bankruptcy or insolvency. In the case of an event of default arising from certain events of bankruptcy or insolvency with respect to the Issuers or any Guarantor, all 2027 WLV Notes then outstanding will become due and payable immediately without further action or notice. The Issuers and certain of their subsidiaries will guarantee and secure their obligations under the Wynn America Credit Facilities with liens on substantially all of their assets, with such liens limiting the amount of such obligations secured to 15% of their Total Assets (as defined in the indenture for the 2025 Notes). The 2023 Notes, 2025 Notes and 2027 WLV Notes were offered pursuant to an exemption under the Securities Act. The 2023 Notes, 2025 Notes and 2027 WLV Notes were offered only to qualified institutional buyers in reliance on Rule 144A under the Securities Act or outside the United States to certain persons in reliance on Regulation S under the Securities Act. The 2023 Notes, 2025 Notes and 2027 WLV Notes have not been and will not be registered under the Securities Act or under any state securities laws. Therefore, the 2023 Notes, 2025 Notes and 2027 WLV Notes may not be offered or sold within the United States to, or for the account or benefit of, any United States person unless the offer or sale would qualify for a registration exemption from the Securities Act and applicable state securities laws. 5 3/8% First Mortgage Notes due 2022 On May 4, 2017, the Issuers commenced a cash tender offer for any and all of the outstanding 2022 Notes. The Company accepted for purchase valid tenders with respect to $498.0 million and paid a tender premium of $14.6 million . On June 12, 2017, the Issuers redeemed the remaining $402.0 million of the untendered 2022 Notes and discharged the indenture under which the 2022 Notes were issued. The Company paid a premium of $10.8 million related to this redemption. In connection with the 2027 WLV Notes issuance and the 2022 Notes cash tender offer and subsequent redemption, the Company recorded a loss on extinguishment of debt of $20.8 million . First Mortgage Notes due 2020 In February 2015, the Issuers commenced a cash tender offer for any and all of the outstanding 2020 Notes. The Company paid a tender premium of $98.9 million for all valid tenders. In May 2015 and August 2015, the Company redeemed the remaining untendered 2020 Notes and paid a premium of $5.9 million . In connection with the 2025 Notes issuance and the 2020 cash tender offer and subsequent redemptions, the Company recorded a loss on extinguishment of debt of $123.9 million . Redemption Price Promissory Note Based on the Board of Directors' finding of "unsuitability," on February 18, 2012, the Company redeemed and canceled Aruze's 24,549,222 shares of Wynn Resorts' common stock. Following a finding of "unsuitability," Wynn Resorts' articles of incorporation authorize redemption of the shares held by unsuitable persons at a "fair value" redemption price. The Company engaged an independent financial advisor to assist in the fair value calculation and concluded that a discount to the then-current trading price was appropriate because of, among other things, restrictions on most of the shares held by Aruze under the terms of the Stockholders Agreement (as defined below). Pursuant to its articles of incorporation, the Company issued the Redemption Note to Aruze, a former stockholder and related party, in redemption of the shares. The Redemption Note has a principal amount of approximately $1.94 billion , matures on February 18, 2022 and bears interest at the rate of 2% per annum payable annually in arrears on each anniversary of the date of the Redemption Note. The Company may, in its sole and absolute discretion, at any time and from time to time, and without penalty or premium, prepay the whole or any portion of the principal or interest due under the Redemption Note. In no instance shall any payment obligation under the Redemption Note be accelerated except in the sole and absolute discretion of the Company or as specifically mandated by law. The indebtedness evidenced by the Redemption Note is and shall be subordinated in right of payment, to the extent and in the manner provided in the Redemption Note, to the prior payment in full of all existing and future obligations of Wynn Resorts and any of its affiliates in respect of indebtedness for borrowed money of any kind or nature. The Company recorded the Redemption Note at fair value in accordance with applicable accounting guidance. As of December 31, 2017 and 2016 , the fair value of the Redemption Note was $1.88 billion and $1.82 billion , respectively. The Okada Parties have challenged the rede

Related Party Transactions	Related Party Transactions Related Party Share Redemption Based on the Board of Directors' finding of "unsuitability," on February 18, 2012, the Company redeemed and canceled Aruze's 24,549,222 shares of Wynn Resorts' common stock. Following a finding of "unsuitability," Wynn Resorts' articles of incorporation authorize redemption of the shares held by unsuitable persons at a "fair value" redemption price. The Company engaged an independent financial advisor to assist in the fair value calculation and concluded that a discount to the then-current trading price was appropriate because of, among other things, restrictions on most of the shares which were subject to the terms of an existing stockholder agreement. Pursuant to its articles of incorporation, the Company issued the Redemption Note to Aruze, a former stockholder and related party, in redemption of the shares. The Okada Parties have challenged the redemption of Aruze's shares and the Company is currently involved in litigation with those parties as well as related stockholder derivative litigation. The outcome of these various proceedings cannot be predicted. The Company's claims and the Okada Parties' counterclaims are in a preliminary stage and management has determined that based on proceedings to date, it is currently unable to determine the probability of the outcome of this matter or the range of reasonably possible loss, if any. An adverse judgment or settlement involving payment of a material amount could cause a material adverse effect on our financial condition. Amounts Due to Officers The Company periodically provides services to Mr. Wynn and certain executive officers and directors of the Company, including the personal use of employees, construction work and other personal services, for which Mr. Wynn, the officers and directors reimburse the Company. Mr. Wynn also reimburses the Company for personal usage of aircraft (subject to a $250,000 credit per calendar year) pursuant to a time-sharing agreement. Mr. Wynn and officers and directors have deposits with the Company to prepay any such items, which are replenished on an ongoing basis as needed. As of December 31, 2017 and 2016 , Mr. Wynn and the officers and directors had a net deposit balance with the Company of $0.4 million and $0.3 million , respectively. Villa Lease Mr. Wynn currently leases property at Wynn Las Vegas for use as his personal residence and pays Wynn Las Vegas, LLC annual rent at its fair market value of the accommodations based on independent third-party expert opinions of value. Pursuant to the 2013 Second Amended and Restated Agreement of Lease, as amended (the "Second A&R Lease"), Mr. Wynn leased three fairway villas as his personal residence and paid $525,000 per year from November 5, 2013 through February 28, 2015, and $559,295 per year from March 1, 2015 through November 3, 2016. In December 2016, Mr. Wynn and Wynn Las Vegas, LLC replaced the Second A&R Lease with a Third Amended and Restated Agreement of Lease, which was effective November 3, 2016 (the "Third A&R Lease"), to reduce the space leased to Mr. Wynn as his personal residence and to adjust the annual rent paid to $305,680 per year. The lease, including each amendment and restatement, have been approved by the Audit Committee of the Board of Directors of Wynn Resorts and provides that Wynn Las Vegas, LLC pays for all capital improvements to the villas; certain services for, and maintenance of, the villas are included in the annual rent. The Third A&R Lease will terminate no later than June 1, 2018, pursuant to the separation agreement described below. Home Purchase In May 2010, the Company entered into an employment agreement with Linda Chen, who is the Chief Operating Officer of Wynn Macau SA. The term of the employment agreement is through February 24, 2020. Under the terms of the employment agreement, the Company purchased a home in Macau for use by Ms. Chen and has made renovations to the home with total costs of $10.0 million through December 31, 2017 . Upon the occurrence of certain events set forth below, Ms. Chen has the option to purchase the home at the then fair market value of the home (as determined by an independent appraiser) less a discount equal to ten percentage points multiplied by each anniversary of the term of the agreement that has occurred (the "Discount Percentage"). The option is exercisable for (a) no consideration at the end of the term, (b) $1.00 in the event of termination of Ms. Chen's employment without "cause" or termination of Ms. Chen's employment for "good reason" following a "change of control" or (c) at a price based on the applicable Discount Percentage in the event Ms. Chen terminates the agreement due to material breach by the Company. Upon Ms. Chen's termination for "cause," Ms. Chen will be deemed to have elected to purchase the Macau home based on the applicable Discount Percentage unless the Company determines to not require Ms. Chen to purchase the home. If Ms. Chen's employment terminates for any other reason before the expiration of the term (e.g., because of her death or disability or due to revocation of her gaming license), the option will terminate. Plane Option Agreement On January 3, 2013, the Company and Mr. Wynn entered into an agreement pursuant to which Mr. Wynn agreed to terminate a previously granted option to purchase an approximately two acre tract of land located on the Wynn Las Vegas golf course and, in return, the Company granted Mr. Wynn the right to purchase any or all of the aircraft owned by the Company or its direct wholly owned subsidiaries. The aircraft purchase option was exercisable upon 30 days written notice and at a price equal to the book value of such aircraft, and terminated on February 6, 2018. The "Wynn" Surname Rights Agreement On August 6, 2004, the Company entered into agreements with Mr. Wynn that confirm and clarify the Company's rights to use the "Wynn" surname and Mr. Wynn's persona in connection with its casino resorts. Under the parties' Surname Rights Agreement, Mr. Wynn granted the Company an exclusive, fully paid-up, perpetual, worldwide license to use, and to own and register trademarks and service marks incorporating the "Wynn" surname for casino resorts and related businesses, together with the right to sublicense the name and marks to its affiliates. Pursuant to the separation agreement described below, if the Company ceases to use the "Wynn" surname and trademark, the Company will assign all of its right, title, and interest in the "Wynn" trademark to Mr. Wynn and terminate the Surname Rights Agreement. Under the parties' Rights of Publicity License, Mr. Wynn granted the Company the exclusive, royalty-free, worldwide right to use his full name, persona and related rights of publicity for casino resorts and related businesses, together with the ability to sublicense the persona and publicity rights to its affiliates, until October 24, 2017. Consulting Agreement From March 1, 2015 to September 30, 2015, Wynn Resorts Development, LLC, a direct subsidiary of the Company ("WRD"), was party to a consulting agreement with a consulting firm of which Clark T. Randt, Jr., current member of the Company's Board of Directors, is the president and sole owner, pursuant to which Ambassador Randt provided advice to WRD. The consulting agreement was terminated in connection with Ambassador Randt joining the Company's Board of Directors. WRD paid the consulting firm $0.6 million in fees and reimbursed expenses under the consulting agreement. Separation Agreement On February 6, 2018, Mr. Wynn resigned as Chairman of the Board of Directors and Chief Executive Officer of the Company and on February 15, 2018, Mr. Wynn entered into a separation agreement with the Company specifying the terms of his termination of service with the Company (the "Separation Agreement"). The Separation Agreement terminates Mr. Wynn's employment agreement with the Company and confirms that Mr. Wynn is not entitled to any severance payment or other compensation from the Company under his employment agreement. Under the Separation Agreement, Mr. Wynn agrees not to compete against the Company for a period of two years and to provide reasonable cooperation and assistance to the Company in connection with any private litigation or arbitration and to the Board of Directors of the Company or any committee of the Board of Directors in connection with any investigation by the Company related to his service with the Company. The Separation Agreement provides that (i) Mr. Wynn's lease of his personal residence at Wynn Las Vegas will terminate not later than June 1, 2018 and until such date Mr. Wynn shall continue to pay rent at its fair market value as described above, unless Mr. Wynn elects to terminate the lease before such date, (ii) Mr. Wynn's current healthcare coverage will terminate on December 31, 2018, and (iii) administrative support for Mr. Wynn will terminate on May 31, 2018. Additionally, in order to conduct any sales of Company shares in an orderly fashion in the event that Mr. Wynn is permitted to and elects to sell any shares that he owns, the Company has agreed to enter into a registration rights agreement with Mr. Wynn, with Mr. Wynn to reimburse the Company for its reasonable expenses. Pursuant to such registration rights agreement, Mr. Wynn may not sell during any quarter after the date of such agreement more than one-third of the Company shares he holds as of the date of such agreement.

Compensation and Retirement Disclosure [Abstract]
Benefit Plans	Benefit Plans Defined contribution plans The Company established a retirement savings plan under Section 401(k) of the Internal Revenue Code covering its U.S. non-union employees in July 2000. The plan allows employees to defer, within prescribed limits, a percentage of their income on a pre-tax basis through contributions to this plan. The Company matches 50% of employee contributions, up to 6% of employees' eligible compensation. For the years ended December 31, 2017 and 2016, there was no employer matching cap. For the year ended December 31, 2015, there was a one-time annual matching cap per employee of $1,200 . During the years ended December 31, 2017 , 2016 and 2015 , the Company recorded matching contribution expenses of $6.1 million , $6.1 million and $3.2 million , respectively. Wynn Macau also operates a defined contribution retirement benefits plan (the "Wynn Macau Plan"). Eligible employees are allowed to contribute 5% of their salary to the Wynn Macau Plan and the Company matches any contributions. The assets of the Wynn Macau Plan are held separately from those of the Company in an independently administered fund. The Company's matching contributions vest to the employee at 10% per year with full vesting in ten years . Forfeitures of unvested contributions are used to reduce the Company's liability for its contributions payable. During the years ended December 31, 2017 , 2016 and 2015 , the Company recorded matching contribution expenses of $15.8 million , $12.9 million and $11.2 million , respectively. Multi-employer pension plan Wynn Las Vegas, LLC contributes to a multi-employer defined benefit pension plan for certain of its union employees under the terms of the Southern Nevada Culinary and Bartenders Union collective-bargaining agreement, which expires in July 2021. The legal name of the multi-employer pension plan is the Southern Nevada Culinary and Bartenders Pension Plan (the "Plan") (EIN: 88-6016617 Plan Number: 1). The Company recorded expenses of $11.5 million , $9.3 million and $9.4 million for contributions to the Plan for the years ended December 31, 2017 , 2016 and 2015 , respectively. For the 2016 plan year, the most recent for which plan data is available, the Company's contributions were identified by the Plan to exceed 5% of total contributions for that year. Based on information the Company received from the Plan, it was certified to be in neither endangered nor critical status for the 2016 plan year. Risks of participating in a multi-employer plan differ from single-employer plans for the following reasons: (1) assets contributed to a multi-employer plan by one employer may be used to provide benefits to employees of other participating employers; (2) if a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers; and (3) if a participating employer stops participating, it may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

Under the WRL 2002 Plan, a maximum of 12,750,000 shares of the Company's common stock was reserved for issuance.

Under the approval of the Omnibus Plan, no new awards may be made under the WRL 2002 Plan. The outstanding awards under the WRL 2002 Plan were transferred to the Omnibus Plan and will remain pursuant to their existing terms and related award agreements. The Company reserved 4,409,390 shares of its common stock for issuance under the Omnibus Plan. These shares were transferred from the remaining available amount under the WRL 2002 Plan. The Omnibus Plan is administered by the Compensation Committee (the "Committee") of the Wynn Resorts, Limited Board of Directors. The Committee has discretion under the Omnibus Plan regarding which type of awards to grant, the vesting and service requirements, exercise price and other conditions, in all cases subject to certain limits. For stock options, the exercise price of stock options must be at least equal to the fair market value of the stock on the date of grant and the maximum term of such an award is 10 years .

The Share Award Plan allows for the grant of nonvested shares of WML's common stock to eligible employees. The Share Award Plan is administered by WML's Board of Directors and has been mandated under the plan to allot, issue and process the transfer of a maximum of 50,000,000 shares. The Board of Directors has discretion on the vesting and service requirements, exercise price and other conditions, subject to certain limits. As of December 31, 2017, there were 34,838,793 shares available for issuance under the Share Award Plan. The summary of nonvested share activity under the Share Award Plan for the year ended December 31, 2017 is presented below: Shares Weighted Average Grant Date Fair Value Nonvested as of January 1, 2017 14,009,134 $ 2.61 Granted 2,726,097 $ 2.22 Vested (3,318,500 ) $ 3.79 Forfeited (1,574,024 ) $ 1.98 Nonvested as of December 31, 2017 11,842,707 $ 2.24 The following is provided for share awards under the Share Award Plan (in thousands, except weighted average grant date fair value): Years Ended December 31, 2017 2016 2015 Weighted average grant date fair value $ 2.22 $ 1.38 $ 1.95 Fair value of shares vested $ 6,884 $ — $ — As of December 31, 2017, there was $11.7 million of unamortized compensation expense, which is expected to be recognized over a weighted average period of 2.53 years. Compensation Cost The total compensation cost for stock-based compensation plans is allocated as follows (in thousands): Years Ended December 31, 2017 2016 2015 Casino $ 6,954 $ 11,304 $ 9,858 Rooms 655 374 318 Food and beverage 1,466 1,060 1,050 Entertainment, retail and other 147 82 82 General and administrative 34,749 30,398 26,978 Pre-opening expenses — 504 189 Total stock-based compensation expense 43,971 43,722 38,475 Total stock-based compensation capitalized 80 92 350 Total stock-based compensation costs $ 44,051 $ 43,814 $ 38,825 Certain members of the Company's executive management team receive a portion of their annual incentive bonus in shares of the Company's stock. The number of shares is determined based on the closing stock price on the date the annual incentive bonus is settled. As the number of shares is variable, the Company records a liability for the fixed monetary amount over the service period. For the year ended December 31, 2017, the Company recorded $23.7 million of stock-based compensation expense associated with these awards and issued $21.9 million of immediately vested shares in December 2017 and $1.8 million of immediately vested shares in January 2018 to settle this liability. For the year ended December 31, 2016, the Company recorded $19.2 million of stock-based compensation expense associated with these awards and issued immediately vested shares in January 2017 to settle this liability. During the years ended December 31, 2017 , 2016 and 2015 , the Company recognized income tax benefits in the Consolidated Statements of Income of $10.8 million , $10.4 million and $8.3 million , respectively, related to stock-based compensation expense. Additionally, during the years ended December 31, 2017 , 2016 and 2015 , the Company realized tax benefits of $25.4 million , $6.7 million and $6.7 million , respectively, related to stock option exercises and restricted stock vesting that occurred in those years. The Company uses the Black-Scholes option pricing model to determine the estimated fair value for stock options. Dividend yield is based on the estimate of annual dividends expected to be paid at the time of the grant. Expected volatility is based on implied and historical factors related to the Company's common stock. The risk-free interest rate used for each period presented is based on the U.S. Treasury yield curve for stock options issued under the Omnibus Plan and the Hong Kong Exchange Fund rates for stock options issued under the Share Option Plan, both at the time of grant for the period equal to the expected term. Expected term represents the weighted average time between the option's grant date and its exercise date. The Company uses historical award exercise activity and termination activity in estimating the expected term for the Omnibus Plan and Share Option Plan. The fair value of stock options granted under the Omnibus Plan was estimated on the date of grant using the following weighted average assumptions: Years Ended December 31, 2017 2016 2015 Expected dividend yield — % 2.0 % 3.6 % Expected volatility — % 45.4 % 44.1 % Risk-free interest rate — % 1.1 % 1.3 % Expected term (years) — 6.0 6.0 The fair value of stock options granted under WML's Share Option Plan was estimated on the date of grant using the following weighted average assumptions: Years Ended December 31, 2017 2016 2015 Expected dividend yield 5.7 % 6.3 % 5.0 % Expected volatility 41.5 % 42.6 % 41.3 % Risk-free interest rate 1.1 % 1.0 % 1.3 % Expected term (years) 6.5 6.5 6.5

In October 2015, Wynn Macau SA received an additional five-year exemption, effective January 1, 2016, from Macau's Complementary Tax on casino gaming profits through December 31, 2020. Accordingly, for the years ended December 31, 2017 , 2016 and 2015 , the Company was exempted from the payment of $63.0 million , $27.3 million and $41.6 million in such taxes or $0.61 , $0.27 and $0.41 per diluted share, respectively. The Company's non-gaming profits remain subject to the Macau Complementary Tax and its casino winnings remain subject to the Macau special gaming tax and other levies in accordance with its concession agreement. In July 2011, Wynn Macau SA received an extension of its agreement with the Macau government that provides for an annual payment of MOP 15.5 million (approximately $1.9 million ) as complementary tax otherwise due by stockholders of Wynn Macau SA on dividend distributions through 2015. In August 2016, Wynn Macau SA received an extension of the agreement for an additional five years applicable to tax years 2016 through 2020. The extension agreement provides for an annual payment of MOP 12.8 million (approximately $1.6 million ). As a result of the stockholder dividend tax agreements, income tax expense includes $1.6 million for each of the years ended December 31, 2017 and 2016 and $1.9 million for the year ended December 31, 2015 . The Macau special gaming tax is 35% of gross gaming revenue. U.S. tax laws only allow a foreign tax credit ("FTC") up to 35% of foreign source income. In February 2010, the Company and the IRS entered into a Pre-Filing Agreement ("PFA") providing that the Macau special gaming tax qualifies as a tax paid in lieu of an income tax and could be claimed as a U.S. FTC. In December 2017, the U.S. Tax Cuts and Jobs Act ("U.S tax reform") was enacted. Also in December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act ("SAB 118"), which allows the Company to record provisional amounts during a measurement period not to extend beyond one year from the enactment date. For the year ended December 31, 2017, the Company recorded a provisional net tax benefit of $339.9 million . The provisional net tax benefit primarily consists of a $273.9 million provisional tax benefit from the increase in the foreign tax credit carryovers, net of valuation allowance, generated as a result of the deemed repatriation of deferred foreign income as well as a $66.0 million provisional tax benefit resulting from the revaluation of the Company's net deferred tax liabilities due to the decrease in the U.S. corporate tax rate from 35% to 21%. This provisional net tax benefit is based on the Company's initial analysis of the U.S. tax reform and may be adjusted over the next 12 months as the Company collects additional information and evaluates any regulatory guidance. Any subsequent adjustment to this amount will be recorded to the current income tax expense in the period in which the amount is determined. During the years ended December 31, 2017 , 2016 and 2015 , the Company recognized tax benefits of $746.6 million , $170.5 million and $264.1 million , respectively (net of valuation allowance and uncertain tax positions), for FTCs generated from the earnings of Wynn Macau SA. Accounting standards require recognition of a future tax benefit to the extent that realization of such benefit is more likely than not; otherwise, a valuation allowance is applied. During the years ended December 31, 2017 and 2016 , the aggregate valuation allowance for deferred tax assets increased by $103.7 million and decreased by $44.2 million , respectively. The 2017 increase is primarily related to FTC carryforwards and other foreign deferred tax assets that are not considered more likely than not realizable. The 2016 decrease is primarily related to a release of valuation allowance on prior year FTCs expected to be utilized as a result of the sale of a 49.9% ownership interest in Retail Joint Venture. The Company recorded tax benefits resulting from the exercise of nonqualified stock options and the value of vested restricted stock and accrued dividends of $2.6 million , $0.8 million and $0.4 million for the years ended December 31, 2017 , 2016 and 2015 , respectively, in excess of the amounts reported for such items as compensation costs under accounting standards related to stock-based compensation. The tax effects of significant temporary differences representing net deferred tax assets and liabilities consisted of the following (in thousands): December 31, 2017 2016 Deferred tax assets—U.S.: Foreign tax credit carryforwards $ 3,616,872 $ 3,269,781 Receivables, inventories, accrued liabilities and other 19,356 37,391 Stock-based compensation 5,084 18,740 Pre-opening expenses 2,716 6,516 Other tax credit carryforwards 1,999 2,413 Intangibles and related other 770 21,404 Other 86 7,958 3,646,883 3,364,203 Less: valuation allowance (3,273,292 ) (3,201,406 ) 373,591 162,797 Deferred tax liabilities—U.S.: Property and equipment (106,979 ) (176,611 ) Redemption Note fair value (13,139 ) (42,806 ) Prepaid insurance, maintenance and taxes (10,391 ) (7,913 ) Other (2,549 ) (2,028 ) (133,058 ) (229,358 ) Deferred tax assets—Foreign: Net operating loss carryforwards 74,345 50,258 Property and equipment 36,299 29,998 Pre-opening expenses 10,717 12,944 Other 1,493 2,946 122,854 96,146 Less: valuation allowance (117,175 ) (85,317 ) 5,679 10,829 Deferred tax liabilities—Foreign: Property and equipment (5,679 ) (10,829 ) Net deferred tax asset (liability) $ 240,533 $ (66,561 ) As of December 31, 2017 , the Company had FTC carryforwards (net of uncertain tax positions) of $3.62 billion . Of this amount, $590.6 million will expire in 2018, $110.9 million in 2019, $530.4 million in 2020, $540.3 million in 2021, $756.0 million in 2023, $710.7 million in 2024, $47.2 million in 2025 and $330.8 million in 2027. The Company has no U.S. tax loss carryforwards. The Company incurred foreign tax losses of $319.1 million , $317.3 million and $124.4 million during the tax years ended December 31, 2017 , 2016 and 2015 , respectively. These foreign tax loss carryforwards expire in 2020, 2019 and 2018, respectively. In assessing the need for a valuation allowance, the Company considered whether it is more likely than not that the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. In the assessment of the valuation allowance, appropriate consideration was given to all positive and negative evidence including recent operating profitability, forecast of future earnings and the duration of statutory carryforward periods. As of December 31, 2017 and 2016 , the Company had valuation allowances of $3.27 billion and $3.20 billion , respectively, provided on FTCs expected to expire unutilized and valuation allowances of $3.5 million and $4.4 million provided on other U.S. deferred tax assets. As of December 31, 2017 and 2016 , the Company had valuation allowances of $117.2 million and $85.3 million , respectively, provided on its foreign deferred tax assets. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): December 31, 2017 2016 2015 Balance—beginning of year $ 90,523 $ 88,314 $ 88,884 Increases based on tax positions of the current year 8,520 5,930 3,051 Settlements with taxing authorities — — (354 ) Lapses in statutes of limitations (3,807 ) (3,721 ) (3,267 ) Balance—end of year $ 95,236 $ 90,523 $ 88,314 As of December 31, 2017 , 2016 and 2015 , unrecognized tax benefits of $95.2 million , $90.3 million and $88.3 million , respectively, were recorded as reductions in deferred income taxes, net. As of December 31, 2016, $0.2 million of unrecognized tax benefits were recorded in other long-term liabilities. The Company had no unrecognized tax benefits recorded in other long-term liabilities as of December 31, 2017 and 2015. As of December 31, 2017 , 2016 and 2015 , $26.9 million , $22.6 million and $20.9 million , respectively, of unrecognized tax benefits would, if recognized, impact the effective tax rate. The Company recognizes penalties and interest related to unrecognized tax benefits in the provision for income taxes. During each of the years ended December 31, 2017 and 2016, the Company recognized $0.9 million in interest in the provision for income taxes. During the year ended 2015 , the Company recognized $0 interest and penalties. The Company anticipates that the 2013 statute of limitations will expire in the next 12 months for certain foreign tax jurisdictions. Also, the Company's unrecognized tax benefits include certain income tax accounting methods, which govern the timing and deductibility of income tax deductions. As a result, the Company's unrecognized tax benefits could increase up to $4.0 million over the next 12 months. The Company files income tax returns in the U.S. federal jurisdiction, various states and foreign jurisdictions. The Company's income tax returns are subject to examination by the IRS and other tax authorities in the locations where it operates. The Company's 2002 to 2013 domestic income tax returns remain subject to examination by the IRS to the extent tax attributes carryforward to future years. The Company's 2014 to 2016 domestic income tax returns also remain subject to examination by the IRS. The Company's 2013 to 2016 Macau income tax returns remain subject to examination by the Financial Services Bureau. The Company has participated in the IRS Compliance Assurance Program ("CAP") for the 2012 through 2017 tax years and will continue to participate in the IRS CAP for the 2018 tax year. In February 2016, 2017 and 2018 the Company received notification that the IRS completed its examination of the Company's 2014, 2015 and 2016 U.S. income tax returns, respectively. There were no changes in its unrecognized tax benefits as a result of the completion of these examinations. In December 2015, the Financial Services Bureau completed an examination of the 2012 Macau income tax return of Wynn Macau SA. On December 31, 2015, the statute of limitations for the 2010 Macau Complementary Tax return expired. As a result of the exam settlement and the expiration of the statute of limitations for the Macau Complementary Tax return, the total amount of unrecognized tax benefits decreased by $3.6 million . On December 31, 2016, the statute of limitations for the 2011 Macau Complementary tax return expired. As a result of the expiration of the statute of limitations for the Macau Complementary Tax return, the total amount of unrecognized tax benefits decreased by $3.7 million . In April 2016, the Financial Services Bureau commenced an examination of the 2011 and 2012 Macau income tax returns of Palo. In June 2016, the Financial Services Bureau concluded its examination with no changes. On December 31, 2017, the statute of limitations for the 2012 Macau Complementary tax return expired. As a result of the expiration of the statute of limitations for the Macau Complementary Tax return, the total amount of unrecognized tax benefits decreased by $3.8 million . In March 2017, the Financial Services Bureau commenced an examination of the 2013 and 2014 Macau income tax returns of Wynn Macau SA. As of December 31, 2017, based upon the current status of the examination, no changes to the unrecognized tax benefits are required. In July 2017, the Financial Services Bureau commenced an examination of the 2013 and 2014 Macau income tax returns of Palo. In February 2018, the Financial Services Bureau concluded its examination with no changes.

Litigation In addition to the actions noted below, the Company and its affiliates are involved in litigation arising in the normal course of business. In the opinion of management, such litigation is not expected to have a material effect on the Company's financial condition, results of operations and cash flows. Determination of Unsuitability and Redemption of Aruze and Affiliates On February 18, 2012, Wynn Resorts' Gaming Compliance Committee received an independent report by Freeh, Sporkin & Sullivan, LLP (the "Freeh Report") detailing a pattern of misconduct by the Okada Parties. The factual record presented in the Freeh Report included evidence that the Okada Parties had provided valuable items to certain foreign gaming officials who were responsible for regulating gaming in a jurisdiction in which entities controlled by Mr. Okada were developing a gaming resort. Based on the Freeh Report, the Board of Directors of Wynn Resorts determined that the Okada Parties are "unsuitable persons" under Article VII of the Company's articles of incorporation. On that same day, Wynn Resorts redeemed and canceled Aruze's 24,549,222 shares of Wynn Resorts' common stock, and, pursuant to its articles of incorporation, Wynn Resorts issued the Redemption Note to Aruze in redemption of the shares. The Redemption Note has a principal amount of $1.94 billion , matures on February 18, 2022, and bears interest at the rate of 2% per annum, payable annually in arrears on each anniversary of the date of the Redemption Note. For additional information on the redemption and the Redemption Note, see Note 7, "Long-term Debt" and Note 9, "Stockholders' Equity." Redemption Action and Counterclaim On February 19, 2012, Wynn Resorts filed a complaint in the Eighth Judicial District Court, Clark County, Nevada against the Okada Parties (as amended, the "Complaint"), alleging breaches of fiduciary duty and related claims (the "Redemption Action") arising from the activities addressed in the Freeh Report. The Company is seeking compensatory and special damages as well as a declaration that it acted lawfully and in full compliance with its articles of incorporation, bylaws and other governing documents in redeeming and canceling the shares of Aruze. On March 12, 2012, the Okada Parties filed an answer denying the claims and a counterclaim (as amended, the "Counterclaim") that purports to assert claims against the Company, each of the members of the Company's Board of Directors (other than Mr. Okada) and Wynn Resorts' General Counsel (the "Wynn Parties"). The Counterclaim alleges, among other things: (1) that the shares of Wynn Resorts common stock owned by Aruze were exempt from the redemption-for-unsuitability provisions in the Wynn Resorts articles of incorporation (the "Articles") pursuant to certain agreements executed in 2002; (2) that the Wynn Resorts directors who authorized the redemption of Aruze's shares acted at the direction of Mr. Wynn and did not independently and objectively evaluate the Okada Parties' suitability, and by so doing, breached their fiduciary duties; (3) that the Wynn Resorts directors violated the terms of the Wynn Resorts Articles by failing to pay Aruze fair value for the redeemed shares; and (4) that the terms of the Redemption Note that Aruze received in exchange for the redeemed shares, including the Redemption Note's principal amount, duration, interest rate, and subordinated status, were unconscionable. Among other relief, the Counterclaim seeks a declaration that the redemption of Aruze's shares was void, an injunction restoring Aruze's share ownership, damages in an unspecified amount and rescission of the Amended and Restated Stockholders Agreement, dated as of January 6, 2010, by and among Aruze, Mr. Wynn, and Elaine P. Wynn (the "Stockholders Agreement"). On June 19, 2012, Elaine P. Wynn asserted a cross claim against Mr. Wynn and Aruze seeking a declaration that (1) any and all of Elaine P. Wynn's duties under the Stockholders Agreement shall be discharged; (2) the Stockholders Agreement is subject to rescission and is rescinded; (3) the Stockholders Agreement is an unreasonable restraint on alienation in violation of public policy; and/or (4) the restrictions on sale of shares shall be construed as inapplicable to Elaine P. Wynn. On May 17, 2017, Elaine P. Wynn filed an amended cross claim which added Wynn Resorts and Wynn Resorts' General Counsel (together with Mr. Wynn, the "Wynn Cross Defendants") as cross defendants. The amended cross claim substantially repeats its earlier allegations and further alleges that Mr. Wynn engaged in acts of misconduct that, with the Wynn Cross Defendants, resulted in Mr. Wynn allegedly breaching the Stockholders Agreement and violating alleged duties under the Stockholders Agreement by preventing Elaine P. Wynn from being nominated and elected to serve as one of the Company's directors. In addition to continuing to seek the declarations asserted under the original cross claim, the amended cross claim seeks an order compelling Mr. Wynn to comply with the Stockholders Agreement by assuring the nomination and election of Elaine P. Wynn to the Board of Directors and seeks unspecified monetary damages from Mr. Wynn and the Wynn Cross Defendants. On July 10, 2017, the court denied Wynn Resorts' and Wynn Resorts' General Counsel's motions to dismiss, and on July 24, 2017, the court denied Wynn Resorts' motion to sever. The Wynn Cross Defendants will vigorously defend against the claims asserted against them. The 2023 Indenture provides that if Mr. Wynn, together with certain related parties, in the aggregate beneficially owns a lesser percentage of the voting power of the outstanding common stock of the Company than is beneficially owned by any other person, a change of control will have occurred. The 2025 Indenture and the 2027 Indenture each provides that if any event constitutes a "change of control" under the 2023 Indenture, it will constitute a change of control under the 2025 Indenture and the 2027 Indenture, respectively. If the Stockholders Agreement is determined not to be enforceable pursuant to Elaine P. Wynn's cross claim, Mr. Wynn would not beneficially own or control Elaine P. Wynn's shares, which could increase the likelihood that a change in control may occur under the Wynn Las Vegas, LLC debt documents. Under the 2023 Indenture, the 2025 Indenture and the 2027 Indenture, if (1) a change of control occurs and (2) at any time within 60 days after that occurrence, the 2023 Notes or the 2025 Notes, as applicable, are rated below investment grade by both rating agencies that rate such notes and, in the case of the 2027 Indenture, the ratings of the 2027 WLV Notes have decreased below the ratings assigned to the 2027 WLV Notes on the date they were issued as described in the 2027 Indenture, the Company is required to make an offer to each applicable holder to repurchase all or any part of such holder's notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest on the notes purchased, if any, to the date of repurchase (unless the notes have been previously called for redemption). On February 12, 2018, counsel for Mr. Wynn advised the court hearing this matter that Mr. Wynn now agrees that the Stockholders Agreement no longer binds either Mr. Wynn or Elaine P. Wynn. There can be no assurance that the court will concur with the position now taken by Mr. Wynn, or that the Stockholders Agreement will in fact be deemed to no longer bind the parties thereto. On February 16, 2018, the Issuers commenced a Consent Solicitation for a Proposed Amendment to the 2023 Indenture. The Proposed Amendment would conform the definition of change of control relating to ownership of equity interests in the Company to the terms of the 2025 Indenture and 2027 Indenture. Adoption of the Proposed Amendment requires the consent of holders of a majority in aggregate principal amount of the 2023 Notes. The Consent Solicitation will expire on March 6, 2018. Fact discovery closed in November 2017 and expert discovery closed in January 2018. In February 2018, the court ruled upon the parties' various motions for summary judgment and, among other rulings, entered summary judgment in favor of the Wynn Parties and against the Okada Parties related to their claims that the terms of the Redemption Note violated the Articles or were otherwise unconscionable. Trial is scheduled to begin in April 2018. Wynn Resorts will continue to vigorously pursue its claims against the Okada Parties, and Wynn Resorts and the Wynn Parties will continue to vigorously defend against the counterclaims asserted against them. Management has determined that based on proceedings to date, it is currently unable to determine the probability of the outcome of this matter or the range of reasonably possible loss, if any. An adverse judgment or settlement involving payment of a material amount could cause a material adverse effect on Wynn Resorts' financial condition. Litigation Commenced by Kazuo Okada Indemnification Action: On March 20, 2013, Mr. Okada filed a complaint against the Company in Nevada state court for indemnification under the Company's Articles, bylaws and agreements with its directors. The complaint sought advancement of Mr. Okada's costs and expenses (including attorney's fees) incurred pursuant to the various legal proceedings and related regulatory investigations described above. The Company's answer and counterclaim was filed on April 15, 2013. The counterclaim named each of the Okada Parties as defendants and sought indemnification under the Company's Articles for costs and expenses (including attorney's fees) incurred pursuant to the various legal proceedings and related regulatory investigations described above. On April 30, 2013, Mr. Okada filed his reply to the counterclaim. On February 4, 2014, the court entered an order on the parties' stipulation that: (1) dismissed all claims Mr. Okada asserted against the Company; (2) reserved Mr. Okada's right to assert, in the future, any claims for indemnity following the resolution of the Redemption Action; and (3) stayed the claims asserted by the Company against Mr. Okada pending the resolution of the Redemption Action. The Company believes the action commenced by Mr. Okada is without merit and will vigorously defend itself against the claims pleaded against it. Management has determined that based on proceedings to date, it is currently unable to determine the probability of the outcome of this action or the range of reasonably possible loss, if any. Macau Action: On July 3, 2015, WML announced that the Okada Parties filed a complaint in the Court of First Instance of Macau ("Macau Court") against Wynn Macau SA and certain individuals who are or were directors of Wynn Macau SA and or WML (collectively, the "Wynn Macau Parties"). The principal allegations in the lawsuit are that the redemption of the Okada Parties' shares in Wynn Resorts was improper and undervalued, that the previously disclosed payment by Wynn Macau SA to an unrelated third party in consideration of relinquishment by that party of certain rights in and to any future development on the land in Cotai where Wynn Palace is located was unlawful and that the previously disclosed donation by Wynn Resorts to the University of Macau Development Foundation was unlawful. The plaintiffs seek dissolution of Wynn Macau SA and compensatory damages. On July 11, 2017, the Macau Court dismissed all claims by the Okada Parties as unfounded, fined the Okada Parties as vexatious litigants, and ordered the Okada Parties to pay for court costs and the Wynn Macau Parties' attorney's fees. On or about October 16, 2017, the Okada Parties filed formal appeal papers in Macau, which Wynn Macau SA received on November 21, 2017. Wynn Macau SA filed its response on December 21, 2017. The Company believes the action commenced by the Okada Parties is without merit and will vigorously defend itself against the claims pleaded against it. Management has determined that based on proceedings to date, it is currently unable to determine the probability of the outcome of this action or the range of reasonably possible loss, if any. Derivative Litigation Related to Redemption Action Two state derivative actions were commenced against the Company and all members of its Board of Directors in the Eighth Judicial District Court of Clark County, Nevada. These state court actions brought by the following plaintiffs have been consolidated: (1) IBEW Local 98 Pension Fund and (2) Danny Hinson (collectively, the "Derivative Plaintiffs"). The Derivative Plaintiffs filed a consolidated complaint on July 20, 2012 asserting claims for (1) breach of fiduciary duty; (2) abuse of control; (3) gross mismanagement; and (4) unjust enrichment. The claims are against the Company and all Company directors during the applicable period, including Mr. Okada, as well as the Company's Chief Financial Officer who signed financial disclosures filed with the SEC during the applicable periods. The Derivative Plaintiffs claim that the individual defendants failed to disclose to the Company's stockholders the investigation into, and the dispute with director Okada as well as the alleged potential violations of the FCPA related to, the University of Macau Development Foundation donation. The Derivative Plaintiffs seek unspecified monetary damages (compensatory and punitive), disgorgement, reformation of corporate governance procedures, an order directing the Company to internally investigate the donation, as well as attorney's fees and costs. On June 18, 2014, the court entered a stipulation between the parties that provides for a stay of the action and directs the parties, within 45 days of the conclusion of the Redemption Action, to discuss how the derivative action should proceed and to file a joint report with the court. The defendants in these actions are vigorously defending against the claims pleaded against them. Management has determined that based on proceedings to date, it is currently unable to determine the probability of the outcome of these actions or the range of reasonably possible loss, if any. Massachusetts Gaming License Related Action On September 17, 2014, the Massachusetts Gaming Commission ("MGC") designated Wynn MA the award winner of the Greater Boston (Region A) gaming license. On November 7, 2014, the gaming license became effective. On October 16, 2014, the City of Revere, the host community to the unsuccessful bidder for the same license, and the International Brotherhood of Electrical Workers, Local 103 ("IBEW") filed a complaint against the MGC and each of the five gaming commissioners in Suffolk Superior Court in Boston, Massachusetts (the "Revere Action"). The complaint challenges the MGC's decision and alleges that the MGC failed to follow statutory requirements outlined in the Gaming Act. The complaint (1) seeks to appeal the administrative decision, (2) asserts that certiorari provides a remedy to correct errors in proceedings by an agency such as the MGC, (3) challenges the constitutionality of that section of the gaming law which bars judicial review of the MGC's decision to deny an applicant a gaming license, and (4) alleges violations of the open meeting law requirements. The court allowed Mohegan Sun ("Mohegan"), the other applicant for the Greater Boston (Region A) gaming license, to intervene in the Revere Action, and on February 23, 2015, Mohegan filed its complaint. The Mohegan complaint challenges the license award to Wynn MA, seeks judicial review of the MGC's decision, and seeks to vacate the MGC's license award to Wynn MA. On July 1, 2015, the MGC filed motions to dismiss Mohegan's and the City of Revere's complaints. On December 3, 2015, the court granted the motion to dismiss the claims asserted in the Revere Action. Also on December 3, 2015, the court granted the motion to dismiss three of the four counts asserted by Mohegan but denied the motion as to Mohegan's certiorari claim. The City of Revere and IBEW sought immediate appellate review of the dismissal of their claims and the MGC requested immediate appellate review of the court's denial of the MGC's motion to dismiss Mohegan's certiorari claim. All three petitions for interlocutory review were denied. The parties then appealed to the Massachusetts Supreme Judicial Court ("SJC"). On March 10, 2017, the SJC affirmed the trial court's dismissal of the City of Revere's claims and IBEW's claims. The SJC affirmed the court's dismissal of Mohegan's claims except for the certiorari claim, which the SJC remanded to the Suffolk Superior Court. Mohegan filed a motion for judgment on the pleadings on November 3, 2017, and oral argument is scheduled for April 5, 2018. The SJC reversed the trial court's dismissal of the individual plaintiffs' open meeting law claim and remanded that claim to the Suffolk Superior Court. The parties are currently in the discovery phase. Wynn MA was not named in the above complaint. The MGC retained private legal representation at its own nontaxpayer-funded expense. Actions Related to Mr. Wynn Investigations: On January 26, 2018, the Company's Board of Directors formed a Special Committee comprised solely of independent directors to investigate allegations of inappropriate personal conduct by Mr. Wynn in the workplace. On February 12, 2018, the Special Committee announced that its review was expanded to include a comprehensive review of the Company's internal policies and procedures with the goal of employing best practices to maintain a safe and respectful workplace for all employees. Gaming regulators in Massachusetts and Nevada are reviewing these matters, including suitability with respect to the Company and its related licensees, and the Company is cooperating with these regulatory reviews. The gaming regulator in Macau is monitoring and reviewing the situation, and the Company is cooperating. Stockholder Actions: Six stockholder derivative actions have been filed on behalf of the Company in state and federal court located in Clark County, Nevada against certain members of the Company's Board of Directors and, in some cases, the Company's General Counsel. Specifically, (i) on February 6, 2018, Norfolk County Retirement System filed a stockholder derivative action against certain current and former members of the Company's Board of Directors and the Company's General Counsel; (ii) on February 15, 2018, Operating Engineers Construction Industry and Miscellaneous Pension Fund filed a stockholder derivative action against certain current and former members of the Company's Board of Directors; (iii) on February 15, 2018, Boynton Beach Municipal Firefighters' Pension Trust Fund and the Firemen's Retirement System of St. Louis filed a stockholder derivative action against certain current and former members of the Company's Board of Directors and the Company's General Counsel; (iv) on February 15, 2018, Rickey A. Broussard filed a stockholder derivative action against certain current and former members of the Company's Board of Directors and the Company's General Counsel, (v) on February 22, 2018, Thomas P. DiNapoli, Comptroller of the State of New York, as Administrative Head of the New York State and Local Retirement System and trustee of the New York State Common Retirement Fund filed a shareholder derivative action against certain current and former members of the Company's Board of Directors and the Company's General Counsel and (vi) on February 22, 2018, Erste-Sparinvest Kapitalanlagegesellschaft M.B.H. filed a shareholder derivative action against certain current and former members of the Company's Board of Directors and the Company's General Counsel. Each of the complaints alleges, among other things, breach of fiduciary duties in failing to detect, prevent and remedy alleged inappropriate personal conduct by Mr. Wynn in the workplace. Each of the actions seeks to recover for the Company unspecified damages, including restitution and disgorgement of profits, and also seeks to recover attorneys' fees, costs and related expenses for the plaintiff. On February 20, 2018, a securities class action was filed against the Company and certain current and former officers of the Company in the United States District Court, Southern District of New York by John V. Ferris and Joann M. Ferris on behalf of all persons who purchased the Company's common stock between February 28, 2014 and January 25, 2018. The complaint alleges, among other things, certain violations of federal securities laws and seeks to recover unspecified damages as well as attorneys' fees, costs and related expenses for the plaintiffs. The defendants in these actions will vigorously defend against the claims pleaded against them. These actions are in preliminary stages and management has determined that based on proceedings to date, it is currently unable to determine the probability of the outcome of these actions or the range of reasonably possible loss, if any.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company reviews the results of operations for each of its operating segments. Wynn Macau and Encore, an expansion at Wynn Macau, are managed as a single integrated resort and have been aggregated as one reportable segment ("Wynn Macau"). Wynn Palace is presented as a separate reportable segment and is combined with Wynn Macau for geographical presentation. Wynn Las Vegas and Encore, an expansion at Wynn Las Vegas, are managed as a single integrated resort and have been aggregated as one reportable segment ("Las Vegas Operations"). The Company identifies each resort as a reportable segment considering operations within each resort have similar economic characteristics, type of customers, types of services and products, the regulatory environment of the operations and the Company's organizational and management reporting structure. The Company also reviews construction and development activities for each of its projects under development, in addition to its reportable segments. The Company separately identifies capital expenditures and assets for its Wynn Boston Harbor development project. Other Macau primarily represents the Company's Macau holding company. The following tables present the Company's segment information (in thousands): Years Ended December 31, 2017 2016 2015 Net revenues Macau Operations: Wynn Macau $ 2,485,804 $ 2,264,087 $ 2,463,092 Wynn Palace 2,139,154 583,336 — Total Macau Operations 4,624,958 2,847,423 2,463,092 Las Vegas Operations 1,681,410 1,618,874 1,612,791 Total $ 6,306,368 $ 4,466,297 $ 4,075,883 Adjusted Property EBITDA (1) Macau Operations: Wynn Macau $ 760,752 $ 681,509 $ 708,623 Wynn Palace 527,583 103,036 — Total Macau Operations 1,288,335 784,545 708,623 Las Vegas Operations 522,397 474,782 477,166 Total 1,810,732 1,259,327 1,185,789 Other operating expenses Pre-opening 26,692 154,717 77,623 Depreciation and amortization 552,368 404,730 322,629 Property charges and other 29,576 54,822 10,535 Corporate expenses and other 102,560 80,162 76,079 Stock-based compensation 43,971 43,218 38,286 Equity in income from unconsolidated affiliates — 16 1,823 Total other operating expenses 755,167 737,665 526,975 Operating income 1,055,565 521,662 658,814 Other non-operating income and expenses Interest income 31,193 13,536 7,229 Interest expense, net of amounts capitalized (388,664 ) (289,365 ) (300,906 ) Change in interest rate swap fair value (1,056 ) 433 (5,300 ) Change in Redemption Note fair value (59,700 ) 65,043 52,041 Loss on extinguishment of debt (55,360 ) — (126,004 ) Equity in income from unconsolidated affiliates — 16 1,823 Other (21,709 ) (728 ) 1,550 Total other non-operating income and expenses (495,296 ) (211,065 ) (369,567 ) Income before income taxes 560,269 310,597 289,247 Benefit (provision) for income taxes 328,985 (8,128 ) (7,723 ) Net income 889,254 302,469 281,524 Less: Net income attributable to noncontrolling interests (142,073 ) (60,494 ) (86,234 ) Net income attributable to Wynn Resorts, Limited $ 747,181 $ 241,975 $ 195,290 (1) "Adjusted Property EBITDA" is net income before interest, income taxes, depreciation and amortization, pre-opening expenses, property charges and other, management and license fees, corporate expenses and other (including intercompany golf course and water rights leases), stock-based compensation, loss on extinguishment of debt, change in interest rate swap fair value, change in Redemption Note fair value and other non-operating income and expenses, and includes equity in income from unconsolidated affiliates. Adjusted Property EBITDA is presented exclusively as a supplemental disclosure because management believes that it is widely used to measure the performance, and as a basis for valuation, of gaming companies. Management uses Adjusted Property EBITDA as a measure of the operating performance of its segments and to compare the operating performance of its properties with those of its competitors, as well as a basis for determining certain incentive compensation. The Company also presents Adjusted Property EBITDA because it is used by some investors as a way to measure a company's ability to incur and service debt, make capital expenditures and meet working capital requirements. Gaming companies have historically reported EBITDA as a supplement to GAAP. In order to view the operations of their casinos on a more stand-alone basis, gaming companies, including Wynn Resorts, Limited, have historically excluded from their EBITDA calculations pre-opening expenses, property charges, corporate expenses and stock-based compensation, that do not relate to the management of specific casino properties. However, Adjusted Property EBITDA should not be considered as an alternative to operating income as an indicator of the Company's performance, as an alternative to cash flows from operating activities as a measure of liquidity, or as an alternative to any other measure determined in accordance with GAAP. Unlike net income, Adjusted Property EBITDA does not include depreciation or interest expense and therefore does not reflect current or future capital expenditures or the cost of capital. The Company has significant uses of cash flows, including capital expenditures, interest payments, debt principal repayments, income taxes and other non-recurring charges, which are not reflected in Adjusted Property EBITDA. Also, Wynn Resorts' calculation of Adjusted Property EBITDA may be different from the calculation methods used by other companies and, therefore, comparability may be limited.

Summary of Significant Accoun25

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company, its majority-owned subsidiaries and entities the Company identifies as a variable interest entity ("VIE") and of which the Company is determined to be the primary beneficiary. For information on the Company's VIEs, see Note 3, "Retail Joint Venture." In April 2016, the Company dissolved its 50% -owned joint venture operating the Ferrari and Maserati automobile dealership inside Wynn Las Vegas, which was closed in October 2015 and accounted for under the equity method. All significant intercompany accounts and transactions have been eliminated. Certain amounts in the consolidated financial statements for the previous years have been reclassified to be consistent with current year presentation. These reclassifications had no effect on the previously reported net income.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid investments with original maturities of three months or less and include both U.S. dollar-denominated and foreign currency-denominated securities. Cash equivalents are carried at cost, which approximates fair value.
Restricted Cash	Restricted Cash The Company's restricted cash consists of cash held in trust in accordance with WML's share award plan and additionally as of December 31, 2016, collateral associated with borrowings under a revolving credit facility.
Investment Securities	Investment Securities Investment securities consist of domestic and foreign short-term and long-term investments in corporate bonds, commercial paper and U.S. government agency bonds reported at fair value, with unrealized gains and losses, net of tax, reported in other comprehensive income (loss). Short-term investments have a maturity date of less than one year and long-term investments are those with a maturity date greater than one year. The Company limits the amount of exposure to any one issuer with the objective of minimizing the potential risk of principal loss. Management determines the appropriate classification of its securities at the time of purchase and reevaluates such designation as of each balance sheet date. Adjustments are made for amortization of premiums and accretion of discounts to maturity computed under the effective interest method. Such amortization is included in interest income together with realized gains and losses and the stated interest on such securities.
Accounts Receivable and Credit Risk	Accounts Receivable and Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of casino accounts receivable. The Company issues credit in the form of "markers" to approved casino customers following investigations of creditworthiness. As of December 31, 2017 and 2016 , 81.7% and 88.1% , respectively, of the Company's markers were due from customers residing outside the United States, primarily in Asia. Business or economic conditions or other significant events in these countries could affect the collectability of such receivables. Accounts receivable, including casino and hotel receivables, are typically non-interest bearing and are initially recorded at cost. An estimated allowance for doubtful accounts is maintained to reduce the Company's receivables to their carrying amount, which approximates fair value. The allowance estimate reflects specific review of customer accounts and outstanding gaming promoter accounts as well as management's experience with historical and current collection trends and current economic and business conditions. Accounts are written off when management deems them to be uncollectible. Recoveries of accounts previously written off are recorded when received.
Inventories	Inventories Inventories consist of retail merchandise and food and beverage items, which are stated at the lower of cost or market value and certain operating supplies. Cost is determined by the first-in, first-out, weighted average and specific identification methods.
Property and Equipment	Property and Equipment Purchases of property and equipment are stated at cost. Depreciation is provided over the estimated useful lives of the assets using the straight-line method as follows: Estimated Useful Lives (years) Buildings and improvements 10 to 45 Land improvements 10 to 45 Furniture, fixtures and equipment 3 to 20 Leasehold interest in land 25 Airplanes 20 Costs related to improvements are capitalized, while costs of repairs and maintenance are charged to expense as incurred. The cost and accumulated depreciation of property and equipment retired or otherwise disposed of are eliminated from the respective accounts and any resulting gain or loss is included in property charges and other.
Capitalized Interest	Capitalized Interest The interest cost associated with major development and construction projects is capitalized and included in the cost of the project. Interest capitalization ceases once a project is substantially complete or no longer undergoing construction activities to prepare it for its intended use. When no debt is specifically identified as being incurred in connection with a construction project, the Company capitalizes interest on amounts expended on the project using the weighted average cost of the Company's outstanding borrowings.
Intangible Assets	Intangible Assets The Company's indefinite-lived intangible assets consist primarily of water rights acquired as part of the original purchase price of the property on which Wynn Las Vegas is located, and trademarks. Indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually. The Company's finite-lived intangible assets consist primarily of its Macau gaming concession and Massachusetts gaming license. Finite-lived intangible assets are amortized over the shorter of their contractual terms or estimated useful lives.
Long-Lived Assets	Long-Lived Assets Long-lived assets, which are to be held and used, including intangible assets and property and equipment, are periodically reviewed by management for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. If an indicator of impairment exists, the Company compares the estimated future cash flows of the asset, on an undiscounted basis, to the carrying value of the asset. If the undiscounted cash flows exceed the carrying value, no impairment is indicated. If the undiscounted cash flows do not exceed the carrying value, then impairment is measured as the difference between fair value and carrying value, with fair value typically based on a discounted cash flow model. If an asset is still under development, future cash flows include remaining construction costs.
Debt Issuance Costs	Debt Issuance Costs Direct and incremental costs and original issue discounts and premiums incurred in connection with the issuance of long-term debt are deferred and amortized to interest expense using the effective interest method or, if the amounts approximate the effective interest method, on a straight-line basis. Debt issuance costs incurred in connection with the issuance of the Company's revolving credit facilities are presented in noncurrent assets on the Consolidated Balance Sheets. All other debt issuance costs are presented as a direct reduction of long-term debt on the Consolidated Balance Sheets.
Redemption Price Promissory Note	Redemption Price Promissory Note The Redemption Price Promissory Note (the "Redemption Note") is recorded at fair value in accordance with applicable accounting guidance. As of December 31, 2017 and 2016, the fair value of the Redemption Note was $1.88 billion and $1.82 billion , respectively. In determining this fair value, the Company estimated the Redemption Note's present value using discounted cash flows with a probability weighted expected return for redemption assumptions and a discount rate, which included time value and non-performance risk adjustments commensurate with the risk of the Redemption Note. Considerations for the redemption assumptions included the stated maturity of the Redemption Note, uncertainty of the related cash flows, as well as potential effects of the following: uncertainties surrounding the potential outcome and timing of pending litigation with Aruze USA, Inc. ("Aruze"), Universal Entertainment Corporation and Mr. Kazuo Okada (collectively, the "Okada Parties") (see Note 14, "Commitments and Contingencies"); the outcome of ongoing investigations of Aruze by the U.S. Attorney's Office, the U.S. Department of Justice and the Nevada Gaming Control Board; and other potential legal and regulatory actions. In addition, in the furtherance of various future business objectives, the Company considered its ability, at its sole option, to prepay the Redemption Note at any time in accordance with its terms without penalty. Accordingly, the Company reasonably determined that the estimated life of the Redemption Note could be less than its contractual life. In determining the appropriate discount rate to be used to calculate the estimated present value, the Company considered the Redemption Note's subordinated position and credit risk relative to all other debt in the Company's capital structure and credit ratings associated with the Company's traded debt. Observable inputs for the risk free rate were based on Federal Reserve rates for U.S. Treasury securities and the credit risk spread was based on a yield curve index of similarly rated debt.
Derivative Financial Instruments	Derivative Financial Instruments Derivative financial instruments are used to manage interest rate and foreign currency exposures. These derivative financial instruments include interest rate swaps and foreign currency forward contracts. The fair value of derivative financial instruments is recognized as an asset or liability at each balance sheet date, with changes in fair value affecting net income as the Company's derivative financial instruments do not qualify for hedge accounting. The fair value approximates the amount the Company would pay if these contracts were settled at the respective valuation dates. Fair value is estimated based upon current, and predictions of future, interest rate levels along a yield curve, the remaining duration of the instruments and other market conditions, and therefore, is subject to significant estimation and a high degree of variability and fluctuation between periods. The fair value is adjusted, to reflect the impact of credit ratings of the counterparties or the Company, as applicable. These adjustments resulted in a reduction in the fair values as compared to their settlement values. The Company had three interest rate swap agreements intended to hedge a portion of the underlying interest rate risk on borrowings under our Wynn Macau Credit Facilities, which matured in July 2017. Under two of the swap agreements, the Company paid a fixed interest rate (excluding the applicable interest margin) of 0.73% on notional amounts corresponding to borrowings of HK $3.95 billion (approximately $505.1 million ) incurred under the Wynn Macau Credit Facilities in exchange for receipts on the same amount at a variable interest rate based on the applicable HIBOR at the time of payment. These interest rate swaps fixed the all-in interest rate on such amounts at 2.23% to 2.98% . Under the third swap agreement, the Company paid a fixed interest rate (excluding the applicable interest margin) of 0.68% on notional amounts corresponding to borrowings of $243.8 million incurred under the Wynn Macau Credit Facilities in exchange for receipts on the same amount at a variable rate based on the applicable LIBOR at the time of payment. This interest rate swap fixed the all-in interest rate on such amounts at 2.18% to 2.93% .
Revenue Recognition and Promotional Allowances	Revenue Recognition and Promotional Allowances The Company recognizes revenues at the time persuasive evidence of an arrangement exists, the service is provided or the retail goods are sold, prices are fixed or determinable and collection is reasonably assured. Casino revenues are measured by the aggregate net difference between gaming wins and losses, with liabilities recorded as customer deposits for funds deposited by customers before gaming play occurs and for chips in the customer's possession. The commissions rebated directly or indirectly through games promoters to customers, cash discounts, other cash incentives and points earned by customers from the Company's loyalty programs are recorded as a reduction to casino revenues. Rooms, food and beverage, entertainment and other operating revenues are recognized when services are performed or events are held. Entertainment, retail and other revenue includes rental income, which is recognized on a time proportion basis over the lease term. Contingent rental income is recognized when the right to receive such rental income is established according to the lease agreements. Advance deposits on rooms and advance ticket sales are recorded as customer deposits until services are provided to the customer. The retail value of rooms, food and beverage, entertainment and other services provided to guests without charge is included in gross revenues and are then deducted as promotional allowances.
Customer Loyalty Program	Customer Loyalty Programs The Company offers loyalty programs at both its Macau Operations and its Las Vegas Operations. Under the program at its Macau Operations, customers earn points based on their level of table games and slots play, which can be redeemed for free play, gifts and complimentary dining and retail shopping. Under the program at its Las Vegas Operations, customers earn points based on their level of slots play, which can be redeemed for free play. The points are recognized as a liability and as a separate element of the gaming transaction with allocation of the consideration received between the points and gaming transaction. The initial recognition of the point liability is at fair value based on points earned multiplied by redemption value, less an estimate for points not expected to be redeemed. The revenue from the points is recognized when redeemed.
Gaming Taxes	Gaming Taxes The Company is subject to taxes based on gross gaming revenues in the jurisdictions in which it operates, subject to applicable jurisdictional adjustments, which taxes are recorded as casino expenses in the accompanying Consolidated Statements of Income.
Advertising Costs	Advertising Costs The Company expenses advertising costs the first time the advertising takes place. Advertising costs incurred in development periods are included in pre-opening costs. Once a project is completed, advertising costs are primarily included in general and administrative expenses.
Pre-Opening Expenses	Pre-Opening Expenses Pre-opening expenses represent personnel, advertising, and other costs incurred prior to the opening of new ventures and are expensed as incurred.
Income Taxes	Income Taxes The Company is subject to income taxes in the U.S. and foreign jurisdictions where it operates. Accounting standards require the recognition of deferred tax assets, net of applicable reserves, and liabilities for the estimated future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on the income tax provision and deferred tax assets and liabilities generally is recognized in the results of operations in the period that includes the enactment date. Accounting standards also require recognition of a future tax benefit to the extent that realization of such benefit is more likely than not; otherwise, a valuation allowance is applied. The Company's income tax returns are subject to examination by the Internal Revenue Service ("IRS") and other tax authorities in the locations where it operates. The Company assesses potentially unfavorable outcomes of such examinations based on accounting standards for uncertain income taxes. The accounting standards prescribe a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. Uncertain tax position accounting standards apply to all tax positions related to income taxes. These accounting standards utilize a two-step approach for evaluating tax positions. If a tax position, based on its technical merits, is deemed more likely than not to be sustained, then the tax benefit is measured as the largest amount of benefit that is more likely than not to be realized upon settlement. As applicable, the Company will recognize accrued penalties and interest related to unrecognized tax benefits in the provision for income taxes.
Foreign Currency	Foreign Currency Gains or losses from foreign currency remeasurements are included in other income (expense) in the accompanying Consolidated Statements of Income. Balance sheet accounts are translated at the exchange rate in effect at each balance sheet date and income statement accounts are translated at the average rate of exchange prevailing during the year. Translation adjustments resulting from this process are charged or credited to other comprehensive income.
Comprehensive Income	Comprehensive Income and Accumulated Other Comprehensive Income (Loss) Comprehensive income includes net income and all other non-stockholder changes in equity, or other comprehensive income (loss). Components of the Company's comprehensive income are reported in the accompanying Consolidated Statements of Stockholders' Equity and Consolidated Statements of Comprehensive Income. The balance of accumulated other comprehensive income (loss) consists of currency translation adjustments and net unrealized gains or losses on available-for-sale securities. The following table presents the changes by component, net of tax and noncontrolling interests, in accumulated other comprehensive income (loss) of the Company (in thousands): Foreign Unrealized Accumulated December 31, 2016 $ 2,213 $ (729 ) $ 1,484 Current period other comprehensive loss (2,766 ) (563 ) (3,329 ) December 31, 2017 $ (553 ) $ (1,292 ) $ (1,845 )
Fair Value Measurements	Fair Value Measurements The Company measures certain of its financial assets and liabilities, at fair value on a recurring basis pursuant to accounting standards for fair value measurements. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. These accounting standards establish a three-tier fair value hierarchy, which prioritizes the inputs used to measure fair value. These tiers include: • Level 1 - Observable inputs such as quoted prices in active markets. • Level 2 - Inputs other than quoted prices in active markets that are either directly or indirectly observable. • Level 3 - Unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
Earnings Per Share	Earnings Per Share Basic earnings per share ("EPS") is computed by dividing net income attributable to Wynn Resorts by the weighted average number of shares outstanding during the year. Diluted EPS is computed by dividing net income attributable to Wynn Resorts by the weighted average number of common shares outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potential dilutive securities had been issued. Potentially dilutive securities include outstanding stock options and unvested restricted stock.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation in accordance with accounting standards, which require the compensation cost relating to share-based payment transactions be recognized in the Company's Consolidated Statements of Income. The cost is measured at the grant date, based on the estimated fair value of the award using the Black-Scholes option pricing model for stock options, and based on the closing share price of the Company's stock on the grant date for nonvested share awards. The cost is recognized as an expense on a straight-line basis over the employee's requisite service period (the vesting period of the award). The Company's stock-based employee compensation arrangements are more fully discussed in Note 12, "Stock-Based Compensation."
Recently Issued and Adopted Accounting Standards	Accounting Standards Issued But Not Yet Adopted In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows - Restricted Cash (Topic 230), which amends the existing guidance relating to the disclosure of restricted cash and restricted cash equivalents on the statement of cash flows. The ASU requires that amounts generally described as restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The ASU will be effective for the Company on January 1, 2018, with early adoption permitted. The Company will adopt this ASU in the first quarter of 2018 and does not expect a material impact on its Consolidated Statements of Cash Flows. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes - Intra-Entity Transfers of Assets Other than Inventory (Topic 740), which requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs, rather than deferring such recognition until the asset is sold to an outside party. The ASU will be effective for the Company on January 1, 2018, with early adoption permitted. The amendments in the new guidance should be adopted on a retrospective basis. The Company will adopt this ASU in the first quarter of 2018 and does not expect a material impact on its Consolidated Financial Statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments (Topic 230), which clarifies the classification of certain cash receipts and cash payments on the statement of cash flows. In particular, the new guidance clarifies the classification related to several types of cash flows, including items such as debt extinguishment costs and distributions received from equity method investees. The new guidance also provides a three-step approach for classifying cash receipts and payments that have aspects of more than one class of cash flows. The ASU will be effective for the Company on January 1, 2018, with early adoption permitted. The Company will adopt this ASU in the first quarter of 2018 and does not expect a material impact on its Consolidated Statements of Cash Flows. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which amends the existing guidance relating to the definition of a lease, recognition of lease assets and lease liabilities on the balance sheet, and the disclosure of key information about leasing activities. Under the new guidance, lessees will be required to recognize a right-of-use asset and lease liability on the balance sheet, measured on a discounted basis. Operating leases were previously not recognized on the balance sheet. Lessor accounting will remain largely unchanged, other than certain targeted improvements intended to align lessor accounting with the lessee accounting model and with the updated revenue recognition guidance issued in 2014. Lessees and lessors are required to apply a modified retrospective transition approach for leases existing at the beginning of the earliest comparative period presented in the adoption-period financial statements. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. The ASU will be effective for the Company on January 1, 2019, with early adoption permitted. The Company is currently assessing the impact the guidance will have on its Consolidated Financial Statements and related disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 824-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which requires equity investments to be measured at fair value with changes in fair value recognized through net income (other than those accounted for under the equity method of accounting or those that result in consolidation of the investee). The update also requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. This update eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. The ASU will be effective for the Company on January 1, 2018 with early adoption permitted. The Company will adopt this ASU in the first quarter of 2018 and is currently assessing the impact the adoption of this standard will have on its Consolidated Financial Statements. The Company expects a portion of the change in its Redemption Note fair value currently included in the Consolidated Statements of Income will be recorded in Accumulated Other Comprehensive Income (Loss) on its Consolidated Balance Sheet. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing revenue recognition guidance and creates a new topic for Revenue from Contracts with Customers. The new guidance is expected to clarify the principles for revenue recognition and to develop a common revenue standard for GAAP applicable to revenue transactions. This guidance provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. This guidance also provides substantial revision of interim and annual disclosures. The update allows for either full retrospective adoption, meaning the guidance is applied for all periods presented, or modified retrospective adoption, meaning the guidance is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the guidance recognized at the date of initial application. The Company will adopt this ASU in the first quarter of 2018 on a full retrospective basis. The Company continues to assess the impact this ASU will have on its Consolidated Financial Statements. Adoption of this standard will change the presentation of, and accounting for, goods and services provided to customers without charge currently included in both gross revenues and promotional allowances in the Consolidated Statements of Income. The total promotional allowances will be netted against gross revenues with the majority of the impact resulting in a decrease in casino revenues and the estimated cost of providing the promotional allowances will no longer be allocated primarily to casino expenses. Additionally, certain commission arrangements with third parties will be reclassified out of operating expenses and netted against revenue. Upon retrospective application on January 1, 2018, management estimates the previously reported net revenue and operating expense amounts for the years ended December 31, 2017 and 2016, will decrease by amounts not expected to exceed $240.0 million and $130.0 million , respectively, primarily due to changes in the accounting for certain commissions. The adoption of this guidance is not expected to have a material impact on the Company's financial condition or net income.
Redemption Price Promissory Note Policy [Policy Text Block]	Redemption Price Promissory Note The Redemption Price Promissory Note (the "Redemption Note") is recorded at fair value in accordance with applicable accounting guidance. As of December 31, 2017 and 2016, the fair value of the Redemption Note was $1.88 billion and $1.82 billion , respectively. In determining this fair value, the Company estimated the Redemption Note's present value using discounted cash flows with a probability weighted expected return for redemption assumptions and a discount rate, which included time value and non-performance risk adjustments commensurate with the risk of the Redemption Note. Considerations for the redemption assumptions included the stated maturity of the Redemption Note, uncertainty of the related cash flows, as well as potential effects of the following: uncertainties surrounding the potential outcome and timing of pending litigation with Aruze USA, Inc. ("Aruze"), Universal Entertainment Corporation and Mr. Kazuo Okada (collectively, the "Okada Parties") (see Note 14, "Commitments and Contingencies"); the outcome of ongoing investigations of Aruze by the U.S. Attorney's Office, the U.S. Department of Justice and the Nevada Gaming Control Board; and other potential legal and regulatory actions. In addition, in the furtherance of various future business objectives, the Company considered its ability, at its sole option, to prepay the Redemption Note at any time in accordance with its terms without penalty. Accordingly, the Company reasonably determined that the estimated life of the Redemption Note could be less than its contractual life. In determining the appropriate discount rate to be used to calculate the estimated present value, the Company considered the Redemption Note's subordinated position and credit risk relative to all other debt in the Company's capital structure and credit ratings associated with the Company's traded debt. Observable inputs for the risk free rate were based on Federal Reserve rates for U.S. Treasury securities and the credit risk spread was based on a yield curve index of similarly rated debt.
