Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Organization Wynn Resorts, Limited, a Nevada corporation (together with its subsidiaries, "Wynn Resorts" or the "Company") is a developer, owner and operator of destination casino resorts (integrated resorts). 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 Palace and Wynn Macau 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 Palace features a luxury hotel tower with 1,706 guest rooms, suites and villas, approximately 424,000 square feet of casino space, 13 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. 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, 12 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. Las Vegas Operations Wynn Las Vegas features two luxury hotel towers with a total of 4,748 guest rooms, suites and villas, approximately 192,000 square feet of casino space, 32 food and beverage outlets, approximately 290,000 square feet of meeting and convention space, approximately 106,000 square feet of retail space (the majority of which is owned and operated under a joint venture of which the Company owns 50.1% ), as well as two theaters, three nightclubs and a beach club and recreation and leisure facilities. In December 2016, the Company entered into a joint venture arrangement (the "Retail Joint Venture") with Crown Acquisitions Inc. ("Crown") to own and operate approximately 88,000 square feet of existing retail space. 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 fourth quarter of 2018. For more information on the Retail Joint Venture, see Note 12, "Retail Joint Venture." Development Projects The Company is currently constructing Encore Boston Harbor, an integrated resort in Everett, Massachusetts, adjacent to Boston along the Mystic River. The resort will contain a hotel, a waterfront boardwalk, meeting and convention space, casino space, a spa, retail offerings and food and beverage outlets. The Company expects to open Encore Boston Harbor in mid-2019. The Company is currently constructing approximately 430,000 square feet of additional meeting and convention space at Wynn Las Vegas and has begun design and site preparation for the reconfiguration of the Wynn Las Vegas golf course, which the Company closed in the fourth quarter of 2017. The Company expects to reopen the golf course in the fourth quarter of 2019 and open the additional meeting and convention space in the first quarter of 2020. Basis of Presentation The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures herein are adequate to make the information presented not misleading. In the opinion of management, all adjustments (which, except as otherwise described in Note 2 below, include only normal recurring adjustments) necessary for a fair presentation of the results for the interim periods have been made. The results for the three and nine months ended September 30, 2018 are not necessarily indicative of results to be expected for the full fiscal year. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 .

Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company, its majority-owned subsidiaries and entities the Company identifies as a variable interest entity ("VIE") for which the Company is determined to be the primary beneficiary. For information on the Company's VIEs, see Note 12, "Retail Joint Venture." All intercompany accounts and transactions have been eliminated. Certain prior period amounts have been reclassified to be consistent with current year presentation. Such reclassifications relate to the adoption of new accounting guidance as further described below in "Recently Adopted Accounting Standards" and had no effect on the previously reported net income. Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents consist of 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, cash equivalents and restricted cash consisted of the following (in thousands): September 30, December 31, Cash and cash equivalents: Cash (1) $ 1,521,691 $ 2,354,244 Cash equivalents (2) 427,562 450,230 1,949,253 2,804,474 Restricted cash (3) 3,747 2,160 Total cash, cash equivalents and restricted cash $ 1,953,000 $ 2,806,634 (1) Cash consists of cash on hand and bank deposits. (2) Cash equivalents consist of bank time deposits and money market funds. (3) Restricted cash consists of cash collateral associated with an obligation and cash held in a trust in accordance with WML's share award plan. Investment Securities Investment securities consist of domestic and foreign short-term and long-term investments in corporate 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. 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. Each quarter, the Company validates the fair value pricing methodology to determine if the fair value is consistent with applicable accounting guidance and to confirm that the securities are classified properly in the fair value hierarchy. The Company compares the pricing received from its vendors to independent sources for the same or similar 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 September 30, 2018 and December 31, 2017 , approximately 84.3% and 81.7% , 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): September 30, December 31, Casino $ 192,646 $ 173,664 Hotel 14,629 22,487 Other 55,782 58,577 263,057 254,728 Less: allowance for doubtful accounts (30,385 ) (30,600 ) $ 232,672 $ 224,128 Derivative Financial Instruments The Company uses derivative financial instruments to manage interest rate exposure. The fair value of derivative financial instruments is recognized as an asset or liability at each balance sheet date, with changes in fair value recorded in earnings as the Company's derivative financial instruments do not qualify for hedge accounting. In accordance with the terms of the Retail Term Loan Agreement (as defined in Note 6, "Long-Term Debt"), the Retail Borrowers (as defined in Note 6, "Long-Term Debt") entered into a five -year interest rate collar with a notional value of $615 million for a cash payment of $3.9 million in July 2018. The interest rate collar establishes a range whereby the Retail Borrowers will pay the counterparty if one-month LIBOR falls below the established floor rate of 1.00% , and the counterparty will pay the Retail Borrowers if one-month LIBOR exceeds the ceiling rate of 3.75% . The interest rate collar settles monthly commencing in August 2019 through the termination date in August 2024. No payments or receipts are exchanged on interest rate collar contracts unless interest rates rise above or fall below the pre-determined ceiling or floor rate, respectively. The Company measures the fair value of the interest rate collar at each balance sheet date based on a Black-Scholes option pricing model, which incorporates observable market inputs such as market volatility and interest rates, with changes in fair value recorded in earnings. As of September 30, 2018 , the fair value of the interest rate collar was $3.8 million and was recorded in other assets in the accompanying Condensed Consolidated Balance Sheet. Redemption Note On February 18, 2012, pursuant to its articles of incorporation, the Company redeemed and canceled all Aruze USA, Inc.’s ("Aruze") 24,549,222 shares of Wynn Resorts’ common stock. In connection with the redemption of the shares, the Company issued a promissory note (the "Redemption Note") with a principal amount of $1.94 billion , a maturity date of February 18, 2022 and an interest rate of 2% per annum, payable annually in arrears on each anniversary of the date of the Redemption Note. The Redemption Note was recorded at fair value in accordance with applicable accounting guidance. The Company repaid the principal amount in full on March 30, 2018. As of December 31, 2017, the fair value of the Redemption Note was $1.88 billion . 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 litigation with Aruze, Universal Entertainment Corporation and Mr. Kazuo Okada (collectively, the "Okada Parties") (see Note 13, "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. Revenue Recognition The Company’s revenue contracts with customers consist of casino wagers and sales of rooms, food and beverage, entertainment, retail and other goods and services. Gross casino revenues are measured by the aggregate net difference between gaming wins and losses. The Company applies a practical expedient by accounting for its casino wagering transactions on a portfolio basis versus an individual basis as all wagers have similar characteristics. Commissions rebated to customers either directly or indirectly through games promoters and cash discounts and other cash incentives earned by customers are recorded as a reduction of casino revenues. In addition to the wager, casino transactions typically include performance obligations related to complimentary goods or services provided to incentivize future gaming or in exchange for points earned under the Company’s loyalty programs. For casino transactions that include complimentary goods or services provided by the Company to incentivize future gaming, the Company allocates the standalone selling price of each good or service to the appropriate revenue type based on the good or service provided. Complimentary goods or services that are provided under the Company’s control and discretion and supplied by third parties are recorded as an operating expense. 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 goods or services provided by the Company. 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. For casino transactions that include points earned under the Company’s loyalty programs, the Company defers a portion of the revenue by recording the estimated standalone selling price of the earned points that are expected to be redeemed as a liability. Upon redemption of the points for Company-owned goods or services, the standalone selling price of each good or service is allocated to the appropriate revenue type based on the good or service provided. Upon the redemption of the points with third parties, the redemption amount is deducted from the liability and paid directly to the third party. After allocating amounts to the complimentary goods or services provided and to the points earned under the Company’s loyalty programs, the residual amount is recorded as casino revenue when the wager is settled. The transaction price for rooms, food and beverage, entertainment, retail and other transactions is the net amount collected from the customer for such goods and services and is recorded as revenue when the goods are provided, services are performed or events are held. Sales tax and other applicable taxes collected by the Company are excluded from revenues. Advance deposits on rooms and advance ticket sales are performance obligations that are recorded as customer deposits until services are provided to the customer. Revenues from contracts with multiple goods or services are allocated to each good or service based on its relative standalone selling price. Entertainment, retail and other revenue also includes lease revenue, which is recognized on a time proportion basis over the lease term. Contingent lease revenue is recognized when the right to receive such revenue is established according to the lease agreements. 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 Condensed Consolidated Statements of Income. These taxes totaled $638.4 million and $544.7 million for the three months ended September 30, 2018 and 2017 , respectively, and $1.81 billion and $1.56 billion for the nine months ended September 30, 2018 and 2017 , respectively. Comprehensive Income and Accumulated Other Comprehensive 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 Condensed Consolidated Statements of Stockholders' Equity and Condensed Consolidated Statements of Comprehensive Income. The following table presents the changes by component, net of tax and noncontrolling interests, in accumulated other comprehensive loss of the Company (in thousands): Foreign Unrealized Redemption Note Accumulated January 1, 2018 $ (553 ) $ (1,292 ) $ — $ (1,845 ) Cumulative credit risk adjustment (1) — — (9,211 ) (9,211 ) Change in net unrealized gain (loss) (1,530 ) (1,510 ) 7,690 4,650 Amounts reclassified to net income (2) — 2,802 1,521 4,323 Other comprehensive income (loss) (1,530 ) 1,292 9,211 8,973 September 30, 2018 $ (2,083 ) $ — $ — $ (2,083 ) (1) On January 1, 2018, the Company adopted Accounting Standards Update ("ASU") No. 2016-01, Financial Instruments . The adjustment to the beginning balance represents the cumulative effect of the change in instrument-specific credit risk on the Redemption Note. See "Recently Adopted Accounting Standards—Financial Instruments" below for additional information. (2) The amounts reclassified to net income include $1.8 million for other-than-temporary impairment losses and $1.0 million in realized losses, both related to investment securities, and a $1.5 million realized gain related to the repayment of the Redemption Note. 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 tables present assets and liabilities carried at fair value (in thousands): Fair Value Measurements Using: September 30, Quoted Other Unobservable Assets: Cash equivalents $ 427,562 $ — $ 427,562 — Restricted cash $ 3,747 $ 2,007 $ 1,740 — Interest rate collar $ 3,845 — $ 3,845 — Fair Value Measurements Using: December 31, 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 — Recently Adopted Accounting Standards Revenue Recognition Standard In May 2014, the Financial Accounting Standards Board ("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 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 substantially revises required interim and annual disclosures. The Company adopted the guidance on January 1, 2018, which resulted in the following significant impacts on its Condensed Consolidated Financial Statements: • The promotional allowances line item was eliminated from the Condensed Consolidated Statements of Income with the majority of the amount being netted against casino revenues. • The estimated cost of providing complimentary goods or services will no longer be allocated primarily to casino expenses from other operating departments as the new guidance requires revenues and expenses associated with providing complimentary goods or services to be classified based on the goods or services provided. • The portion of junket commissions previously recorded as a casino expense is now recorded as a reduction of casino revenue. • Mandatory service charges on food and beverage are now recorded on a gross basis with the amount received from the customer recorded as food and beverage revenue and the corresponding amount paid to employees recorded as food and beverage expense. Certain prior period amounts have been adjusted to reflect the full retrospective adoption of the guidance. There was no impact on the Company’s financial condition, operating income or net income. The table below provides a reconciliation of amounts previously reported and the resulting impacts from the adoption of the new revenue recognition guidance (in thousands): Three Months Ended September 30, 2017 As Previously Reported Adoption of ASC 606 As Adjusted Gross revenues $ 1,728,064 $ (176,717 ) $ 1,551,347 Promotional allowances (115,733 ) 115,733 — Operating revenues 1,612,331 (60,984 ) 1,551,347 Operating expenses 1,355,004 (60,984 ) 1,294,020 Operating income $ 257,327 $ — $ 257,327 Nine Months Ended September 30, 2017 As Previously Reported Adoption of ASC 606 As Adjusted Gross revenues $ 4,954,060 $ (506,064 ) $ 4,447,996 Promotional allowances (336,788 ) 336,788 — Operating revenues 4,617,272 (169,276 ) 4,447,996 Operating expenses 3,863,126 (169,276 ) 3,693,850 Operating income $ 754,146 $ — $ 754,146 Financial Instruments 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 Company adopted this guidance on January 1, 2018, which resulted in a $9.2 million cumulative unrealized loss, net of tax, being recorded to accumulated other comprehensive loss with a corresponding increase to retained earnings. The adjustment represents the portion of the cumulative change in the Redemption Note fair value resulting from the change in the instrument-specific credit risk previously included in other income (expense) on the Condensed Consolidated Statements of Income. Restricted Cash 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 Company adopted this guidance on January 1, 2018 on a retrospective basis and the updated disclosures are reflected for the periods presented in the Condensed Consolidated Statements of Cash Flows. For the nine months ended September 30, 2017 , the change in restricted cash of $190.1 million was previously reported within net cash used in financing activities. Accounting Standards Issued But Not Yet Adopted Leases In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , and subsequent amendments to the initial guidance: ASU No. 2017-13, ASU No. 2018-10, and ASU No. 2018-11 (collectively, "Topic 842"). Topic 842 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 are currently 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. Entities are required to adopt Topic 842 using a modified retrospective transition method at one of the following application dates: (1) the later of the beginning of the earliest period presented in the financial statements and the lease commencement date or (2) on the effective date. The Company will adopt Topic 842 on January 1, 2019 using the effective date transition approach, which will result in a balance sheet presentation that is not comparable to the prior period in the first year of adoption. Topic 842 provides for transition relief by permitting the election of certain practical expedients. The Company is electing the reassessment package of practical expedients, which permits the Company not to reassess whether (1) any expired or existing contracts as of the adoption date are or contain a lease, (2) lease classification remains appropriate for any expired or existing leases as of the adoption date and (3) previously capitalized costs continue to qualify as initial direct costs on expired or existing leases as of the adoption date. While the Company is currently assessing the quantitative impact the guidance will have on its Consolidated Financial Statements and related disclosures, the Company expects the most significant changes will be related to the recognition of right-of-use assets and lease liabilities for operating leases on the Company's Consolidated Balance Sheet, with no material impact to net income or cash flows. Cloud Computing Arrangement Implementation Costs In August 2018, the FASB issued ASU No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract . The ASU is intended to eliminate potential diversity in practice in accounting for costs incurred to implement cloud computing arrangements that are service contracts by requiring customers in such arrangements to follow internal-use software guidance with respect to such costs, with any resulting deferred implementation costs recognized over the term of the contract in the same income statement line item as the fees associated with the hosting element of the arrangement. The ASU will be effective for the Company on January 1, 2020, with early adoption permitted. The Company is currently assessing the impact the guidance will have on its Consolidated Financial Statements and related disclosures.

The ground lease has annual payments of $3.8 million until 2023 and total payments of $370.7 million thereafter. The Company expects to use this land for future development. In accordance with asset acquisition accounting standards, the Company allocated the purchase price to the identifiable assets acquired based on the relative fair value of each component. As a result, the Company recorded $89.1 million of the purchase price as a definite-lived intangible asset, which represents the favorable terms of the assumed ground lease relative to the market.

As of September 30, 2018 and December 31, 2017 , the weighted average interest rate was 3.99% and 3.16% , respectively. As of September 30, 2018 , the Company had $123.9 million of available borrowing capacity under the Wynn Macau Senior Revolving Credit Facility. WML Finance Revolving Credit Facility The Company's credit facilities include a HK$ 3.87 billion (approximately $ 495.1 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. The WML Finance Credit Facility bore interest initially at 1.50% per annum, such rate calculated as the interest rate paid by the lender as the deposit bank for the cash collateral deposited and pledged with the lender plus a margin of 0.40% . On July 18, 2018, the WML Finance Credit Facility matured with no outstanding borrowings. U.S. and Corporate Related Debt Bridge Facility On March 28, 2018, the Company entered into a credit agreement to provide for an $800 million 364 -day term loan (the "Bridge Facility").

The Bridge Facility bore interest at either LIBOR plus 2.75% per annum or base rate plus 1.75% per annum. Redemption Price Promissory Note On March 30, 2018, the Company used the net proceeds from the Bridge Facility, along with cash on hand and borrowings under its WA Senior Revolving Credit Facility (defined below) to repay the Redemption Note principal amount of $1.94 billion pursuant to the Settlement Agreement and Mutual Release ("Settlement Agreement"). See Note 13, "Commitments and Contingencies—Litigation—Redemption Action and Counterclaim" for additional information on the Settlement Agreement. Commitment Letter On September 19, 2018, the Company entered into a commitment letter (as subsequently amended and restated to add additional lenders, the “Commitment Letter”) to provide for a 364 -day term loan facility to the Company in an aggregate principal amount of up to $750 million , which remained fully available as of September 30, 2018. On October 24, 2018, the Company agreed to terminate $500 million of the lenders’ commitments under the Commitment Letter, in anticipation of entering into the new Credit Agreement discussed below. Accordingly, the lenders' remaining commitments under the Commitment Letter are $250 million and expire on December 19, 2018, with an option to extend to April 5, 2019, subject to certain conditions. Wynn Resorts Term Loan On October 30, 2018, the Company and certain subsidiaries of the Company entered into a credit agreement (the "Credit Agreement") to provide for a $500 million six -year term loan facility (the “Term Loan”). The Term Loan matures on October 30, 2024 and bears interest at a rate of LIBOR plus 2.25% per year. The Company intends to use the net proceeds of the Term Loan for general corporate purposes, including, without limitation, repurchases of the Company’s common stock, investments in subsidiaries and/or capital expenditures. Wynn Group Asia, Inc. and Wynn Resorts Holdings, LLC, each a direct, wholly owned subsidiary of the Company (collectively, the “Guarantors”), guarantee the obligations of the Company under the Credit Agreement.

In connection with the amendment, the Company recorded a loss on extinguishment of debt of $1.5 million . Wynn Las Vegas Senior Notes During the first quarter of 2018, Wynn Resorts purchased $20 million principal amount of the 5 1/2% Senior Notes due 2025 (the "2025 Notes") and $20 million principal amount of the 5 1/4% Senior Notes due 2027 (the "2027 Notes") through open market purchases. As of September 30, 2018 , Wynn Resorts holds this debt and has not contributed it to its wholly owned subsidiary, Wynn Las Vegas, LLC. On March 20, 2018, Wynn Las Vegas, LLC and Wynn Las Vegas Capital Corp. (the "Issuers"), wholly owned subsidiaries of the Company, executed a second supplemental indenture (the "Supplemental Indenture") to the Indenture dated May 22, 2013, as supplemented by that certain Supplemental Indenture dated as of February 18, 2015 (the "Indenture"), relating to the Issuers’ 4 1/4% Senior Notes due 2023 (the "2023 Notes"). The Supplemental Indenture amended the Indenture by conforming the definition of "Change of Control" relating to ownership of equity interests in the Company in the Indenture to the terms of the indentures governing the Issuers’ other outstanding notes. As part of executing the Supplemental Indenture, the Issuers paid $25 million to consenting holders of the 2023 Notes. The Company accounted for this transaction as a modification and recorded the $25 million as debt issuance costs on the Condensed Consolidated Balance Sheet. In the second quarter of 2017, the Issuers issued the 2027 Notes and executed a cash tender offer and subsequent redemption for the 5 3/8% First Mortgage Notes due 2022 (the "2022 Notes"). In connection with these transactions, the Company recorded a loss on extinguishment of debt of $20.8 million . Retail Term Loan On July 25, 2018, Wynn/CA Plaza Property Owner, LLC and Wynn/CA Property Owner, LLC (collectively, the "Retail Borrowers"), subsidiaries of the Retail Joint Venture, entered into a term loan agreement (the "Retail Term Loan Agreement"). The Retail Term Loan Agreement provides a term loan facility to the Retail Borrowers of $615 million (the "Retail Term Loan"). The Retail Term Loan is secured by substantially all of the assets of the Retail Borrowers. The Retail Term Loan matures on July 24, 2025 and bears interest at a rate of LIBOR plus 1.70% per annum. As of September 30, 2018 , the interest rate was 3.96% . In accordance with the Retail Term Loan Agreement, the Retail Borrowers entered into an interest rate collar agreement with a LIBOR floor of 1.00% and a ceiling of 3.75% . See Note 2, “Summary of Significant Accounting Policies”, for additional information on the interest rate collar. The Retail Borrowers distributed approximately $589 million of the net proceeds of the Retail Term Loan to their members on a proportionate basis to each member’s ownership percentage. The Retail Borrowers may prepay the Retail Term Loan, in whole but not in part, with a premium of 1.70% of the principal amount prorated for the number of days between the prepayment date and July 25, 2019. Any time subsequent to July 25, 2019, the Retail Borrowers may prepay the Retail Term Loan, in whole or in part, with no premium above the principal amount. The Retail Term Loan Agreement contains customary representations and warranties, events of default and affirmative and negative covenants for debt facilities of this type, including, among other things, limitations on leasing matters, incurrence of indebtedness, distributions and transactions with affiliates. The Retail Term Loan Agreement also provides for customary sweeps of the Retail Borrowers' excess cash in the event of a default or in the event the Retail Borrowers fail to maintain certain financial ratios as defined in the Retail Term Loan Agreement. In addition, the Company will indemnify the lenders under the Retail Term Loan and be liable, in each case, for certain customary environmental and non-recourse carve out matters pursuant to a hazardous materials indemnity agreement and a recourse indemnity agreement, each entered into concurrently with the execution of the Retail Term Loan Agreement. Debt Covenant Compliance Management believes that as of September 30, 2018 , the Company was in compliance with all debt covenants. Fair Value of Long-Term Debt The estimated fair value of the Company's long-term debt as of September 30, 2018 and December 31, 2017 was $8.80 billion and $7.95 billion , respectively, compared to its carrying value of $9.04 billion and $ 7.85 billion . The estimated fair value as of December 31, 2017 excludes the Redemption Note. See Note 2, "Summary of Significant Accounting Policies" for discussion of the estimated fair value of the Redemption Note. The estimated fair value of the Company's long-term debt is based on recent trades, if available, and indicative pricing from market information (Level 2 inputs).

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. The Company recorded stock-based compensation expense associated with these awards of $1.3 million and $4.9 million , for the three months ended September 30, 2018 and 2017 , respectively, and $5.5 million and $14.8 million for the nine months ended September 30, 2018 and 2017 , respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended September 30, 2018 and 2017 , the Company recorded an income tax benefit of $3.9 million and an income tax benefit of $0.5 million , respectively. For the nine months ended September 30, 2018 and 2017, the Company recorded an income tax benefit of $124.6 million and an income tax expense of $5.0 million , respectively. The 2018 income tax benefit primarily related to the settlement of the Redemption Note. The 2017 income tax expense and benefit for these periods primarily related to changes in the domestic valuation allowance for U.S. foreign tax credits ("FTCs"). The Company recorded valuation allowances on certain of its U.S. and foreign deferred tax assets. 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. Wynn Macau SA has received a five -year exemption from complementary tax on profits generated by gaming operations through December 31, 2020. For the three months ended September 30, 2018 and 2017 , the Company was exempt from the payment of such taxes totaling $26.8 million and $15.0 million , respectively. For the nine months ended September 30, 2018 and 2017, the Company was exempt from the payment of such taxes totaling $73.7 million and $41.6 million , respectively. Wynn Macau SA also entered into an agreement with the Macau government that provides for an annual payment of 12.8 million Macau patacas (approximately $1.6 million ) as complementary tax otherwise due by stockholders of Wynn Macau SA on dividend distributions through 2020. 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, which allowed 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 based on the Company's initial analysis of the U.S. tax reform. The Company continues to collect additional information and evaluate regulatory or other guidance that may impact the use of its FTC carryovers, including the treatment of foreign-sourced royalties and the allocation of interest expense and other expenses to foreign source income. The Company may adjust its valuation allowance for FTC carryovers and the provisional net tax benefit over the next three months. Any subsequent adjustment to this amount will be recorded to income tax expense in the period in which the amount is determined, and such adjustments may be significant. During the three and nine months ended September 30, 2018 , no adjustments have been made to the provisional net tax benefit recorded for the year ended December 31, 2017.

Wynn, former Chairman of the Board of Directors and Chief Executive Officer ("Mr. Wynn"), resigned as Chairman of the Board of Directors and Chief Executive Officer of Wynn Resorts 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 terminated Mr. Wynn’s employment agreement with the Company and confirmed 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 agreed 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 provided that (i) Mr. Wynn’s lease of his personal residence at Wynn Las Vegas would terminate not later than June 1, 2018 and until such date Mr. Wynn would continue to pay rent at its fair market value, unless Mr. Wynn elected 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 would terminate on May 31, 2018. Additionally, in order to conduct sales of Company shares in an orderly fashion, the Company agreed to enter into a registration rights agreement with Mr. Wynn, with Mr. Wynn to reimburse the Company for its reasonable expenses. On March 20, 2018, the Company entered into a registration rights agreement with Mr. Wynn, the Wynn Family Limited Partnership, a Delaware limited partnership (together with Mr. Wynn, the "Selling Stockholder") and each holder from time to time a party thereto (the "Registration Rights Agreement"), pursuant to the Separation Agreement. The Selling Stockholder subsequently sold all of its holdings of the Company's common stock through open market transactions pursuant to Rule 144 under the Securities Act of 1933, as amended, and certain privately negotiated transactions. Pursuant to the Registration Rights Agreement, without the Company's prior written consent, the Selling Stockholder was not permitted to sell more than an aggregate of 4,043,903 shares of Common Stock in any quarter. The Company provided written consent permitting the Selling Stockholder to undertake the registered sales. Cooperation Agreement On August 3, 2018, the Company entered into a Cooperation Agreement (the "Cooperation Agreement") with Elaine P. Wynn regarding the composition of the Company’s Board of Directors and certain other matters, including, among other things, the appointment of Mr. Philip G. Satre to the Company's Board of Directors, standstill restrictions, releases, non-disparagement and reimbursement of expenses. The term of the Cooperation Agreement expires on the day after the conclusion of the 2020 annual meeting of the Company’s stockholders, unless earlier terminated pursuant to the circumstances described in the Cooperation Agreement. Amounts Due to Officers The Company periodically provides services to certain executive officers and directors of the Company, including the personal use of employees, construction work and other personal services, for which the officers and directors reimburse the Company. Certain officers and directors have deposits with the Company to prepay any such items, which are replenished on an ongoing basis as needed. As of September 30, 2018 , these net deposit balances with the Company were immaterial.

Retail Joint Venture	Retail Joint Venture In December 2016, the Company sold Crown a 49.9% ownership interest in the Retail Joint Venture for $217.0 million in cash and a $75.0 million interest-free note, which was paid in full on January 3, 2018. As of December 31, 2017, the note was recorded at its present value of $75.0 million in prepaid expenses and other on the Condensed Consolidated Balance Sheet. The Company maintains a 50.1% ownership in the Retail Joint Venture and is 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 September 30, 2018 and December 31, 2017 , the Retail Joint Venture had total assets of $93.5 million and $59.7 million , respectively, and total liabilities of $618.1 million and $0.9 million , respectively.

Commitments and Contingencies	Commitments and Contingencies Encore Boston Harbor Development On April 28, 2017, Wynn MA, LLC ("Wynn MA"), an indirect wholly owned subsidiary of the Company, and Suffolk Construction Company, Inc. (the "Construction Manager"), entered into an agreement concerning the construction of Encore Boston Harbor, which, among other things, confirmed the guaranteed maximum price for the construction work undertaken by the Construction Manager. The Construction Manager is obligated to substantially complete the project by June 24, 2019, for a guaranteed maximum price of $1.32 billion . Both the contract time and guaranteed maximum price are subject to further adjustment under certain conditions. The performance of the Construction Manager is backed by a payment and performance bond in the amount of $350.0 million . 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 were "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. 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 sought 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") purporting to assert claims against the Company, certain individuals who are or were members of the Company's Board of Directors (other than Mr. Okada) and Wynn Resorts' former General Counsel, Kimmarie Sinatra ("Ms. Sinatra"). The Counterclaim alleged, 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 sought 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 March 8, 2018, the Company entered into the Settlement Agreement by and between the Company, Mr. Wynn, Linda Chen, Russell Goldsmith, Ray R. Irani, Robert J. Miller, John A. Moran, Marc D. Schorr, Alvin V. Shoemaker, D. Boone Wayson, Allan Zeman, and Ms. Sinatra (collectively, the "Wynn Parties"), and Universal Entertainment Corp. and Aruze (collectively with Universal Entertainment Corp., the "Universal Parties"). The Settlement Agreement resolved legal proceedings pending in the Redemption Action as well as other claims. Pursuant to the Settlement Agreement, the Company paid the principal amount of the $1.94 billion Redemption Note on March 30, 2018. On March 30, 2018, the Company also paid an additional $463.6 million with respect to the Universal Parties’ claims related to the allegedly below-market interest rate of the Redemption Note and stipulated to the release to Aruze of $232.4 million in accrued interest held in escrow. The Company recorded the $463.6 million as a litigation settlement expense on the Condensed Consolidated Statements of Income. Under the Settlement Agreement, the Wynn Parties and the Universal Parties mutually agreed to unconditionally release all claims against each other relating to or arising out of the Redemption Action, as well as any claims which relate to or arise out of any other litigation or claims in any other jurisdiction. As a result, the Universal Parties will not claim that Aruze remains a party to the Stockholders Agreement. The Universal Parties further released any claims against the Wynn Parties and their affiliates in any other jurisdiction, including but not limited to the proceeding pending in Macau against Wynn Resorts (Macau) S.A. and certain related individuals ("Macau Litigation"). As a result of the Settlement Agreement, the parties to the agreement dismissed all litigation between the Universal Parties and the Company and its then-directors and executives with respect to the redemption, including the Redemption Action and the Macau Litigation, but the Settlement Agreement did not release claims against any parties to such litigation who are not parties to the Settlement Agreement, including but not limited to Kazuo Okada and Elaine P. Wynn. On March 12, 2018, the Company voluntarily dismissed its claim for breach of fiduciary duty against Kazuo Okada, which was the last and only remaining claim between Wynn Resorts, Kazuo Okada, and the Universal Parties in the Redemption Action. 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 should be discharged; (2) the Stockholders Agreement was subject to rescission and is rescinded; (3) the Stockholders Agreement was an unreasonable restraint on alienation in violation of public policy; and/or (4) the restrictions on sale of shares should be construed as inapplicable to Elaine P. Wynn. On March 28, 2016, Elaine P Wynn filed an amended cross claim against Mr. Wynn, as well as Wynn Resorts and Wynn Resorts' former General Counsel (together with Mr. Wynn, the "Wynn Cross Defendants") as cross defendants. The amended cross claim substantially repeated its earlier allegations and further alleged 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 Wynn Resorts' directors. In addition to continuing to seek the declarations asserted under the original cross claim, the amended cross claim sought 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 sought unspecified monetary damages from Mr. Wynn and the Wynn Cross Defendants. Elaine P. Wynn’s amended cross claim was later dismissed as to Wynn Resorts and Wynn Resorts' former General Counsel. On May 17, 2017, Elaine P. Wynn filed another amended cross claim against the Wynn Cross Defendants, which substantially repeated its earlier allegations and again named Wynn Resorts and Wynn Resorts' former General Counsel as cross defendants. On March 14, 2018, Mr. Wynn and Elaine P. Wynn entered into a stipulation declaring the Stockholders Agreement invalid and unenforceable, and on April 16, 2018, the Company entered into a Settlement Agreement and Mutual Release by and between the Company, Mr. Wynn, Elaine P. Wynn, and the Company’s former General Counsel, which, among other things, resolved and unconditionally released the parties from all claims and cross claims asserted among the parties in a legal proceeding involving the Stockholders Agreement. Neither the Company nor the Company’s former General Counsel made any payment under the terms of such settlement agreement. Litigation Commenced by Kazuo Okada 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, 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. In March 2018, pursuant to the Settlement Agreement, the Universal Parties voluntarily withdrew from the Macau Litigation, leaving Mr. Okada as the sole claimant. The Company believes this action is without merit and will vigorously defend itself against the claims pleaded against it by Mr. Okada. 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. In May 2018, the parties (except Elaine P. Wynn) filed a joint report given the conclusion of the Redemption Action. On May 14, 2018, the court stayed the case due to plaintiff Danny Hinson’s claim that he intended to send a demand letter to the Company. On May 30, 2018, plaintiff Danny Hinson sent a demand letter to the Company requesting the Board to investigate the University of Macau Development Foundation donation, the removal of Mr. Okada from the Board and the terms of the Redemption Note. The Company is reviewing the letter. 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 Actions 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. Suffolk Action: On September 17, 2018, Sterling Suffolk Racecourse, LLC, owner of the property proposed for location of a casino by an unsuccessful bidder for the Greater Boston (Region) A gaming license filed a complaint in the United States District Court, District of Massachusetts, against Wynn Resorts, Wynn MA, certain current and former officers of Wynn Resorts, FBT Everett Realty, LLC, former owner of the land on which Encore Boston Harbor is located (“FBT”) and Paul Lohnes, a member of FBT. The complaint alleges, among other things, the defendants engaged in conduct in violation of Racketeer Influenced Corrupt Organization Act (“RICO”), conspired to circumvent the application process for the Greater Boston (Region A) gaming license and violated Massachusetts’ law with respect to unfair methods of competition. The plaintiff seeks $1 billion in compensatory damages and treble damages pursuant to applicable law. The Company will vigorously defend against the claims asserted. This action is 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 this action or the range of reasonably possible loss, if any. Revere Action: 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 being re-scheduled from its originally scheduled date of 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 Revere Action. 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 amended and restated its charter to provide for a review of various governance issues regarding knowledge of the allegations and 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. On August 3, 2018, the Board received the final presentation from the Special Committee. The Special Committee provided the presentation to the Company's gaming regulators in Massachusetts and Nevada, which 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. In deference to the ongoing regulatory investigations, the Board and the Company intends to not make any further public statement on the results of the Special Committee presentation until the regulatory investigations are completed. Derivative Litigation: A number of stockholder derivative actions have been filed purportedly on behalf of the Company in state and federal court located in Clark County, Nevada against certain current and former members of the Company’s Board of Directors and, in some cases, the Company’s current and former officers. 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. On September 19, 2018, the Board established a Special Litigation Committee (the “SLC”) to investigate the allegations in the State Derivative Case (as defined below). The actions filed in the Eighth Judicial District Court of Clark County, Nevada have been consolidated as In re Wynn Resorts, Ltd. Derivative Litigation (“State Derivative Case”). In September 2018, the court denied the Company’s motion to dismiss, and the Company filed a writ petition appealing the denial to the Nevada Supreme Court. In October 2018, the Nevada Supreme Court denied the Company’s writ petition. The SLC has filed a motion to intervene and stay the case. The actions filed in the United States District Court, District of Nevada have been consolidated as In re Wynn Resorts, Ltd. Derivative Litigation (“Federal Derivative Case”), which also claim corporate waste and violation of Section 14(a) of the Exchange Act. In June 2018, the Company filed a motion to dismiss and a motion to stay pending resolution of the Securities Action. The motions are fully-briefed and awaiting a decision from the court. 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. Additional demands have been made to the Company that it commence similar actions and additional lawsuits may be filed in the future. Securities Action: 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 (which was subsequently transferred to the United States District Court, District of Nevada) 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 parties are awaiting an order from the court appointing a lead plaintiff’s counsel. 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, Encore, an expansion at Wynn Las Vegas, and the Retail Joint Venture 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 assets for its Encore 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): Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 (as adjusted) (as adjusted) Operating revenues Macau Operations: Wynn Palace $ 730,572 $ 525,029 $ 2,017,004 $ 1,373,742 Wynn Macau 579,620 562,049 1,741,145 1,753,241 Total Macau Operations 1,310,192 1,087,078 3,758,149 3,126,983 Las Vegas Operations 398,880 464,269 1,271,925 1,321,013 Total $ 1,709,072 $ 1,551,347 $ 5,030,074 $ 4,447,996 Adjusted Property EBITDA (1) Macau Operations: Wynn Palace $ 226,141 $ 138,228 $ 617,317 $ 337,487 Wynn Macau 182,928 183,219 565,677 574,723 Total Macau Operations 409,069 321,447 1,182,994 912,210 Las Vegas Operations 95,298 151,509 362,051 418,296 Total 504,367 472,956 1,545,045 1,330,506 Other operating expenses Litigation settlement — — 463,557 — Pre-opening 13,714 6,908 35,255 19,445 Depreciation and amortization 137,458 137,982 411,685 415,488 Property charges and other 18,830 28,293 30,672 38,494 Corporate expenses and other 31,763 31,943 86,350 73,643 Stock-based compensation 11,619 10,503 28,265 29,290 Total other operating expenses 213,384 215,629 1,055,784 576,360 Operating income 290,983 257,327 489,261 754,146 Other non-operating income and expenses Interest income 6,948 8,447 21,029 21,998 Interest expense, net of amounts capitalized (93,007 ) (95,874 ) (281,132 ) (291,875 ) Change in derivatives fair value (54 ) (2 ) (54 ) (1,056 ) Change in Redemption Note fair value — (41,718 ) (69,331 ) (69,982 ) (Loss) gain on extinguishment of debt (198 ) (20,774 ) 2,131 (43,061 ) Other 11,216 (1,894 ) 1,039 (19,840 ) Total other non-operating income and expenses (75,095 ) (151,815 ) (326,318 ) (403,816 ) Income before income taxes 215,888 105,512 162,943 350,330 Benefit (provision) for income taxes 3,884 457 124,631 (5,040 ) Net income 219,772 105,969 287,574 345,290 Net income attributable to noncontrolling interests (63,657 ) (26,202 ) (180,010 ) (89,791 ) Net income attributable to Wynn Resorts, Limited $ 156,115 $ 79,767 $ 107,564 $ 255,499 (1) "Adjusted Property EBITDA" is net income before interest, income taxes, depreciation and amortization, litigation settlement expense, 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) gain on extinguishment of debt, change in derivatives fair value, change in Redemption Note fair value and other non-operating income and expenses. 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. We also present 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 us, 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 our 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. We have 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, our 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 Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2018
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company, its majority-owned subsidiaries and entities the Company identifies as a variable interest entity ("VIE") for which the Company is determined to be the primary beneficiary. For information on the Company's VIEs, see Note 12, "Retail Joint Venture." All intercompany accounts and transactions have been eliminated. Certain prior period amounts have been reclassified to be consistent with current year presentation. Such reclassifications relate to the adoption of new accounting guidance as further described below in "Recently Adopted Accounting Standards" and had no effect on the previously reported net income.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents consist of 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.
Investment Securities	Investment Securities Investment securities consist of domestic and foreign short-term and long-term investments in corporate 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. 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. Each quarter, the Company validates the fair value pricing methodology to determine if the fair value is consistent with applicable accounting guidance and to confirm that the securities are classified properly in the fair value hierarchy. The Company compares the pricing received from its vendors to independent sources for the same or similar 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 September 30, 2018 and December 31, 2017 , approximately 84.3% and 81.7% , 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.
Derivative Financial Instruments	Derivative Financial Instruments The Company uses derivative financial instruments to manage interest rate exposure. The fair value of derivative financial instruments is recognized as an asset or liability at each balance sheet date, with changes in fair value recorded in earnings as the Company's derivative financial instruments do not qualify for hedge accounting.
Redemption Note	Redemption Note On February 18, 2012, pursuant to its articles of incorporation, the Company redeemed and canceled all Aruze USA, Inc.’s ("Aruze") 24,549,222 shares of Wynn Resorts’ common stock. In connection with the redemption of the shares, the Company issued a promissory note (the "Redemption Note") with a principal amount of $1.94 billion , a maturity date of February 18, 2022 and an interest rate of 2% per annum, payable annually in arrears on each anniversary of the date of the Redemption Note. The Redemption Note was recorded at fair value in accordance with applicable accounting guidance. The Company repaid the principal amount in full on March 30, 2018. As of December 31, 2017, the fair value of the Redemption Note was $1.88 billion . 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 litigation with Aruze, Universal Entertainment Corporation and Mr. Kazuo Okada (collectively, the "Okada Parties") (see Note 13, "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.
Revenue Recognition	Revenue Recognition The Company’s revenue contracts with customers consist of casino wagers and sales of rooms, food and beverage, entertainment, retail and other goods and services. Gross casino revenues are measured by the aggregate net difference between gaming wins and losses. The Company applies a practical expedient by accounting for its casino wagering transactions on a portfolio basis versus an individual basis as all wagers have similar characteristics. Commissions rebated to customers either directly or indirectly through games promoters and cash discounts and other cash incentives earned by customers are recorded as a reduction of casino revenues. In addition to the wager, casino transactions typically include performance obligations related to complimentary goods or services provided to incentivize future gaming or in exchange for points earned under the Company’s loyalty programs. For casino transactions that include complimentary goods or services provided by the Company to incentivize future gaming, the Company allocates the standalone selling price of each good or service to the appropriate revenue type based on the good or service provided. Complimentary goods or services that are provided under the Company’s control and discretion and supplied by third parties are recorded as an operating expense. 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 goods or services provided by the Company. 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. For casino transactions that include points earned under the Company’s loyalty programs, the Company defers a portion of the revenue by recording the estimated standalone selling price of the earned points that are expected to be redeemed as a liability. Upon redemption of the points for Company-owned goods or services, the standalone selling price of each good or service is allocated to the appropriate revenue type based on the good or service provided. Upon the redemption of the points with third parties, the redemption amount is deducted from the liability and paid directly to the third party. After allocating amounts to the complimentary goods or services provided and to the points earned under the Company’s loyalty programs, the residual amount is recorded as casino revenue when the wager is settled. The transaction price for rooms, food and beverage, entertainment, retail and other transactions is the net amount collected from the customer for such goods and services and is recorded as revenue when the goods are provided, services are performed or events are held. Sales tax and other applicable taxes collected by the Company are excluded from revenues. Advance deposits on rooms and advance ticket sales are performance obligations that are recorded as customer deposits until services are provided to the customer. Revenues from contracts with multiple goods or services are allocated to each good or service based on its relative standalone selling price. Entertainment, retail and other revenue also includes lease revenue, which is recognized on a time proportion basis over the lease term. Contingent lease revenue is recognized when the right to receive such revenue is established according to the lease agreements.
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 Condensed Consolidated Statements of Income.
Comprehensive Income (Loss) and Accumulated Other Comprehensive Loss	Comprehensive Income and Accumulated Other Comprehensive 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 Condensed Consolidated Statements of Stockholders' Equity and Condensed Consolidated Statements of Comprehensive Income.
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.
Recently Issued and Adopted Accounting Standards	Recently Adopted Accounting Standards Revenue Recognition Standard In May 2014, the Financial Accounting Standards Board ("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 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 substantially revises required interim and annual disclosures. The Company adopted the guidance on January 1, 2018, which resulted in the following significant impacts on its Condensed Consolidated Financial Statements: • The promotional allowances line item was eliminated from the Condensed Consolidated Statements of Income with the majority of the amount being netted against casino revenues. • The estimated cost of providing complimentary goods or services will no longer be allocated primarily to casino expenses from other operating departments as the new guidance requires revenues and expenses associated with providing complimentary goods or services to be classified based on the goods or services provided. • The portion of junket commissions previously recorded as a casino expense is now recorded as a reduction of casino revenue. • Mandatory service charges on food and beverage are now recorded on a gross basis with the amount received from the customer recorded as food and beverage revenue and the corresponding amount paid to employees recorded as food and beverage expense. Certain prior period amounts have been adjusted to reflect the full retrospective adoption of the guidance. There was no impact on the Company’s financial condition, operating income or net income. The table below provides a reconciliation of amounts previously reported and the resulting impacts from the adoption of the new revenue recognition guidance (in thousands): Three Months Ended September 30, 2017 As Previously Reported Adoption of ASC 606 As Adjusted Gross revenues $ 1,728,064 $ (176,717 ) $ 1,551,347 Promotional allowances (115,733 ) 115,733 — Operating revenues 1,612,331 (60,984 ) 1,551,347 Operating expenses 1,355,004 (60,984 ) 1,294,020 Operating income $ 257,327 $ — $ 257,327 Nine Months Ended September 30, 2017 As Previously Reported Adoption of ASC 606 As Adjusted Gross revenues $ 4,954,060 $ (506,064 ) $ 4,447,996 Promotional allowances (336,788 ) 336,788 — Operating revenues 4,617,272 (169,276 ) 4,447,996 Operating expenses 3,863,126 (169,276 ) 3,693,850 Operating income $ 754,146 $ — $ 754,146 Financial Instruments 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 Company adopted this guidance on January 1, 2018, which resulted in a $9.2 million cumulative unrealized loss, net of tax, being recorded to accumulated other comprehensive loss with a corresponding increase to retained earnings. The adjustment represents the portion of the cumulative change in the Redemption Note fair value resulting from the change in the instrument-specific credit risk previously included in other income (expense) on the Condensed Consolidated Statements of Income. Restricted Cash 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 Company adopted this guidance on January 1, 2018 on a retrospective basis and the updated disclosures are reflected for the periods presented in the Condensed Consolidated Statements of Cash Flows. For the nine months ended September 30, 2017 , the change in restricted cash of $190.1 million was previously reported within net cash used in financing activities. Accounting Standards Issued But Not Yet Adopted Leases In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , and subsequent amendments to the initial guidance: ASU No. 2017-13, ASU No. 2018-10, and ASU No. 2018-11 (collectively, "Topic 842"). Topic 842 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 are currently 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. Entities are required to adopt Topic 842 using a modified retrospective transition method at one of the following application dates: (1) the later of the beginning of the earliest period presented in the financial statements and the lease commencement date or (2) on the effective date. The Company will adopt Topic 842 on January 1, 2019 using the effective date transition approach, which will result in a balance sheet presentation that is not comparable to the prior period in the first year of adoption. Topic 842 provides for transition relief by permitting the election of certain practical expedients. The Company is electing the reassessment package of practical expedients, which permits the Company not to reassess whether (1) any expired or existing contracts as of the adoption date are or contain a lease, (2) lease classification remains appropriate for any expired or existing leases as of the adoption date and (3) previously capitalized costs continue to qualify as initial direct costs on expired or existing leases as of the adoption date. While the Company is currently assessing the quantitative impact the guidance will have on its Consolidated Financial Statements and related disclosures, the Company expects the most significant changes will be related to the recognition of right-of-use assets and lease liabilities for operating leases on the Company's Consolidated Balance Sheet, with no material impact to net income or cash flows. Cloud Computing Arrangement Implementation Costs In August 2018, the FASB issued ASU No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract . The ASU is intended to eliminate potential diversity in practice in accounting for costs incurred to implement cloud computing arrangements that are service contracts by requiring customers in such arrangements to follow internal-use software guidance with respect to such costs, with any resulting deferred implementation costs recognized over the term of the contract in the same income statement line item as the fees associated with the hosting element of the arrangement. The ASU will be effective for the Company on January 1, 2020, with early adoption permitted. The Company is currently assessing the impact the guidance will have on its Consolidated Financial Statements and related disclosures.

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. We also present 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 us, 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 our 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. We have 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, our calculation of Adjusted Property EBITDA may be different from the calculation methods used by other companies and, therefore, comparability may be limited.

Adjusted Property EBITDA	[1]	$ 95,298	$ 151,509	$ 362,051	$ 418,296
[1]	"Adjusted Property EBITDA" is net income before interest, income taxes, depreciation and amortization, litigation settlement expense, 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) gain on extinguishment of debt, change in derivatives fair value, change in Redemption Note fair value and other non-operating income and expenses. 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. We also present 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 us, 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 our 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. We have 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, our calculation of Adjusted Property EBITDA may be different from the calculation methods used by other companies and, therefore, comparability may be limited.
