Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements for the three and nine months ended September 30, 2019 and 2018 have been prepared in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP") and are unaudited. We have condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with GAAP. Although we believe the disclosures made are adequate to prevent the information presented from being misleading, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018. Certain prior year amounts in our condensed consolidated balance sheets have been reclassified to conform to current year presentation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and, accordingly, ultimate results could differ from those estimates. Additionally, interim results are not necessarily indicative of full year performance. In our opinion, the accompanying condensed consolidated financial statements reflect all adjustments, including normal recurring items, considered necessary for a fair presentation of the interim periods. All material intercompany transactions have been eliminated in consolidation. Summary of Significant Accounting Policies Our significant accounting policies are detailed in Note 2: "Basis of Presentation and Summary of Significant Accounting Policies" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018. On January 1, 2019, we adopted the requirements of Accounting Standards Update ("ASU") No. 2016-02 ("ASU 2016-02"), Leases (Topic 842), and the significant accounting policies that changed as a result of the adoption are set forth below. Leases We determine if a contract is or contains a lease at the inception of the contract, and we classify that lease as a finance lease if it meets certain criteria or as an operating lease when it does not. We reassess if a contract is or contains a leasing arrangement upon modification of the contract. For a contract, in which we are a lessee, that contains fixed payments for both lease and non-lease components, we have elected to account for the components as a single lease component, as permitted. At the commencement date of a lease, we recognize a lease liability for future fixed lease payments and a right-of-use ("ROU") asset representing our right to use the underlying asset during the lease term. The lease liability is initially measured as the present value of the future fixed lease payments that will be made over the lease term. The lease term includes lessee options to extend the lease and periods occurring after a lessee early termination option, only to the extent it is reasonably certain that we will exercise such extension options and not exercise such early termination options, respectively. The future fixed lease payments are discounted using the rate implicit in the lease, if available, or our incremental borrowing rate. Our incremental borrowing rate is estimated on a portfolio basis and incorporates lease term, currency risk, credit risk and an adjustment for collateral. Upon adoption of ASU 2016-02, we elected to use the remaining lease term as of January 1, 2019 in our estimation of the applicable discount rate for leases that were in place at adoption. For the initial measurement of the lease liability for leases commencing after January 1, 2019, we use the discount rate as of the commencement date of the lease, incorporating the entire lease term. Additionally, we elected not to recognize leases with lease terms of 12 months or less at the commencement date in our consolidated balance sheets. Current maturities and long-term portions of operating lease liabilities are classified as accounts payable, accrued expenses and other and operating lease liabilities, respectively, and current maturities and long-term portions of finance lease liabilities are classified as current maturities of long-term debt and long-term debt, respectively, in our consolidated balance sheets. The ROU asset is measured at the amount of the lease liability with adjustments, if applicable, for lease prepayments made prior to or at lease commencement, initial direct costs incurred by us and lease incentives. We evaluate the carrying value of ROU assets if there are indicators of impairment and review the recoverability of the related asset group. If the carrying value of the asset group is determined to not be recoverable and is in excess of the estimated fair value, we record an impairment loss in our consolidated statements of operations. ROU assets of operating leases are classified as operating lease right-of-use assets and ROU assets of finance leases are classified as property and equipment, net in our consolidated balance sheets. Our operating leases require: (i) fixed lease payments, or minimum payments, as contractually stated in the lease agreement; (ii) variable lease payments, which, for our hotels, are generally based on a percentage of the underlying asset's revenues or profits, or are dependent on changes in an index; or (iii) lease payments equal to the greater of the fixed or variable lease payments. In addition, during the term of our hotel leases, we may be required to pay some, or all, of the capital costs for furniture, equipment and leasehold improvements in the hotel property. For operating leases, lease expense relating to fixed payments is recognized on a straight-line basis over the lease term, and lease expense related to variable payments is expensed as incurred, with amounts recognized in owned and leased hotel expenses, general and administrative expenses and other expenses from managed and franchised properties in our consolidated statements of operations. For finance leases, the amortization of the asset is recognized over the shorter of the lease term or useful life of the underlying asset within depreciation and amortization expense and other expenses from managed and franchised properties in our consolidated statements of operations. The interest expense related to finance leases, including any variable lease payments, is recognized in interest expense in our consolidated statements of operations. Recently Issued Accounting Pronouncements In August 2018, the Financial Accounting Standards Board ("FASB") issued ASU No. 2018-15 ("ASU 2018-15"), Intangibles – Goodwill and Other – Internal-use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This ASU aligns guidance for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with guidance for capitalizing implementation costs to develop or obtain internal-use software. Capitalized implementation costs will be amortized over the term of the arrangement and presented in the same line item in the statement of operations as the fees associated with the service contract. We elected, as permitted by the standard, to early adopt ASU 2018-15 on a prospective basis as of January 1, 2019. The adoption did not have a material effect on our condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 , which supersedes existing guidance on accounting for leases in Leases (Topic 840) and generally requires all leases, including operating leases, to be recognized in the statement of financial position of lessees as ROU assets and lease liabilities, with certain practical expedients available. Subsequent to ASU 2016-02, the FASB issued related ASUs, including ASU No. 2018-11 ("ASU 2018-11"), Leases (Topic 842): Targeted Improvements, which provides for another transition method in addition to the modified retrospective approach required by ASU 2016-02. This option allows entities to initially apply the new leases standard at the adoption date and recognize a cumulative adjustment to the opening balance of retained earnings in the period of adoption. As described above, we adopted ASU 2016-02 on January 1, 2019 and applied the package of practical expedients included therein, as well as utilized the transition method included in ASU 2018-11. By applying ASU 2016-02 at the adoption date, as opposed to at the beginning of the earliest period presented, the presentation of financial information for periods prior to January 1, 2019 remain unchanged and in accordance with Leases (Topic 840) . On January 1, 2019, we recognized a $256 million cumulative adjustment to accumulated deficit, net of taxes of $81 million related to a decrease to our deferred tax liability, as a result of the impairment of ROU assets that occurred in periods prior to the adoption date.

As a result of the sale, we recognized a pre-tax gain of $81 million included in gain on sale of assets, net in our condensed consolidated statements of operations for the three and nine months ended September 30, 2019.

(2) Primarily the result of changes in estimated transaction prices for our performance obligations related to points issued under Hilton Honors, which had no effect on revenues. We recognized revenues that were previously deferred as contract liabilities of $62 million and $33 million du ring the three months ended September 30, 2019 and 2018, respectively, and $149 million during the nine months ended September 30, 2018. Performance Obligations As of September 30, 2019, we had $442 million of deferred revenues related to unsatisfied performance obligations related to Hilton Honors that will be recognized as revenues when the points are redeemed, which we estimate will occur over the next two years. Additionally, we had $625 million of deferred revenues related to application, initiation and licensing fees, which are expected to be recognized as revenues in future periods over the terms of the related contracts.

Variable Interest Entity, Primary Beneficiary, Does Not Hold Majority Voting Interest, Disclosures [Abstract]
Consolidated Variable Interest Entities	Consolidated Variable Interest Entities As of September 30, 2019 and December 31, 2018, we consolidated two variable interest entities ("VIEs") that lease hotel properties and, as of December 31, 2018, we also consolidated one VIE that is a management company. We consolidated these VIEs since we are the primary beneficiary, having the power to direct the activities that most significantly affect their economic performance. Additionally, we have the obligation to absorb their losses and the right to receive benefits that could be significant to them. The assets of our consolidated VIEs are only available to settle the obligations of the respective entities. In June 2019, the VIE that is a management company, which we had previously consolidated, sold its assets. As a result of the sale, we deconsolidated $7 million of total assets and $3 million of total liabilities, as we no longer had the power to direct the activities that most significantly affect the VIE's economic performance. See Note 13: "Stockholders' Equity (Deficit) and Accumulated Other Comprehensive Loss" for additional information. Our condensed consolidated balance sheets included the assets and liabilities of the VIEs that we consolidated as of the respective periods, which primarily comprised the following: September 30, December 31, 2019 2018 (in millions) Cash and cash equivalents $ 81 $ 71 Property and equipment, net 71 68 Deferred income tax assets 50 53 Other non-current assets 61 58 Accounts payable, accrued expenses and other 59 41 Long-term debt (1) 200 205 Other long-term liabilities 15 15 ____________ (1) Includes finance lease liabilities of $182 million and $187 million as of September 30, 2019 and December 31, 2018, respectively.

In June 2019, we amended the Term Loans to extend the maturity date to June 2026 with a discount of 0.25 percent. In June 2019, we also amended the Revolving Credit Facility to increase the borrowing capacity to $1.75 billion, $250 million of which is available in the form of letters of credit, and extended the maturity date to June 2024. In connection with this amendment, we incurred $7 million of debt issuance costs, which were included in other non-current assets in our condensed consolidated balance sheet as of September 30, 2019. As of September 30, 2019, we had $59 million of outstanding letters of credit, resulting in an available borrowing capacity under the Revolving Credit Facility of $1.69 billion. We are required to pay a commitment fee of 0.125 percent per annum under the Revolving Credit Facility in respect of the unused commitments thereunder. In June 2019, we issued $1.0 billion aggregate principal amount of 4.875% Senior Notes due 2030 (the "2030 Senior Notes") and incurred $15 million of debt issuance costs. Interest on the 2030 Senior Notes is payable semi-annually in arrears on January 15 and July 15 of each year, beginning January 2020. We used a portion of the net proceeds from the issuance of the 2030 Senior Notes to repay $500 million outstanding on our Term Loans and to repay $225 million outstanding under our Revolving Credit Facility. In connection with the amendment and the repayment of the Term Loans, we recognized $10 million of fees and unamortized deferred financing costs and discount, which were included in other non-operating income, net in our condensed consolidated statement of operations for the nine months ended September 30, 2019. The 4.250% Senior Notes due 2024 (the "2024 Senior Notes"), the 4.625% Senior Notes due 2025 (the "2025 Senior Notes"), the 5.125% Senior Notes due 2026 (the "2026 Senior Notes"), the 4.875% Senior Notes due 2027 (the "2027 Senior Notes") and the 2030 Senior Notes are guaranteed on a senior unsecured basis by the Parent and substantially all of its direct and indirect wholly owned domestic subsidiaries that are themselves not issuers of the applicable series of senior notes.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At the end of each quarter, we estimate the effective income tax rate expected to be applied for the full year. The effective income tax rate is determined by the level and composition of income (loss) before income taxes, which is subject to federal, state, local and foreign income taxes. We file income tax returns, including returns for our subsidiaries, with federal, state, local and foreign tax jurisdictions. We are under regular and recurring audit by the Internal Revenue Service ("IRS") and other taxing authorities on open tax positions. The timing of the resolution of tax audits is highly uncertain, as are the amounts, if any, that may ultimately be paid upon such resolution. Changes may result from the conclusion of ongoing audits, appeals or litigation in federal, state, local and foreign tax jurisdictions or from the resolution of various proceedings between the U.S. and foreign tax authorities. As of September 30, 2019, we remain subject to federal and state examinations of our income tax returns for tax years from 2005 through 2018 and foreign examinations of our income tax returns for tax years from 1996 through 2018. Our total unrecognized tax benefits as of September 30, 2019 and December 31, 2018 were $330 million and $318 million, respectively. As of September 30, 2019 and December 31, 2018, we had accrued approximately $46 million and $40 million, respectively, for interest and penalties related to our unrecognized tax benefits in our condensed consolidated balance sheets. Included in the balances of unrecognized tax benefits as of September 30, 2019 and December 31, 2018 was $318 million and $310 million, respectively, associated with positions that, if favorably resolved, would provide a benefit to our effective income tax rate. In April 2014, we received 30-day Letters from the IRS and the Revenue Agents Report ("RAR") for the 2006 and October 2007 tax years. We disagreed with several of the proposed adjustments in the RAR, filed a formal appeals protest with the IRS and did not make any tax payments related to this audit. The issues being protested in appeals relate to assertions by the IRS that: (i) certain foreign currency denominated intercompany loans from our foreign subsidiaries to certain U.S. subsidiaries should be recharacterized as equity for U.S. federal income tax purposes and constitute deemed dividends from such foreign subsidiaries to our U.S. subsidiaries; (ii) in calculating the amount of U.S. taxable income resulting from Hilton Honors, we should not reduce gross income by the estimated costs of future redemptions, but rather such costs would be deductible at the time the points are redeemed; and (iii) certain foreign currency denominated loans issued by one of our Luxembourg subsidiaries whose functional currency is the U.S. dollar ("USD"), should instead be treated as issued by one of our Belgian subsidiaries whose functional currency is the euro ("EUR"), and thus foreign currency gains and losses with respect to such loans should have been measured in EUR, instead of USD. In January 2016, we received a 30-day Letter from the IRS and the RAR for the December 2007 through 2010 tax years, which included proposed adjustments that reflect the carryover effect of the three protested issues from the 2006 through October 2007 tax years. These proposed adjustments are also being protested in appeals and formal appeals protests have been submitted. In April 2016, we requested a Technical Advice Memorandum ("TAM") from the IRS with respect to the treatment of the gains and losses recognized as a result of changes in foreign currency exchange rates on loans issued by our Luxembourg subsidiary. We received a taxpayer favorable TAM in October 2018 and this issue is no longer being pursued by the IRS for any of the open tax years. In September 2018, we received a 30-day Letter from the IRS and the RAR for the 2011 through 2013 tax years, which reflects proposed adjustments for the carryover effect of the two remaining protested issues from the 2006 through October 2007 tax years. The adjustments for the 2011 through 2013 tax years will also be protested in appeals and formal protests have been submitted. After receipt of the TAM relating to the Luxembourg subsidiary, the two remaining proposed adjustments sought by the IRS would result in additional U.S. federal tax owed of approximately $817 million, excluding interest and penalties and potential state income

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation We grant time-vesting restricted stock units and restricted stock (collectively, "RSUs"), nonqualified stock options ("options") and performance-vesting RSUs ("performance shares") to our employees and deferred share units ("DSUs") to members of our board of directors. We recognized share-based compensation expense of $42 million and $35 million during the three months ended September 30, 2019 and 2018, respectively, and $123 million and $103 million during the nine months ended September 30, 2019 and 2018, respectively. As of September 30, 2019, unrecognized compensation costs for unvested awards was approximately $153 million, which are expected to be recognized over a weighted-average period of 1.8 years on a straight-line basis. As of September 30, 2019, there were 14.2 million shares of common stock available for future issuance under the Hilton 2017 Omnibus Incentive Plan, plus any shares subject to awards outstanding under our 2013 Omnibus Incentive Plan, which will become available for issuance under the Hilton 2017 Omnibus Incentive Plan if such outstanding awards expire or are terminated or are canceled or forfeited. RSUs During the nine months ended September 30, 2019, we granted 1.0 million RSUs with a weighted average grant date fair value per share of $83.41, which generally vest in equal annual installments over two Options During the nine months ended September 30, 2019, we granted 0.8 million options with a weighted average exercise price per share of $83.11, which vest over three years from the date of grant in equal annual installments and terminate 10 years from the date of grant or earlier if the individual’s service terminates under certain circumstances. The weighted average grant date fair value per share of the options granted during the nine months ended September 30, 2019 was $21.08, which was determined using the Black-Scholes-Merton option-pricing model with the following assumptions: Expected volatility (1) 23.51 % Dividend yield (2) 0.81 % Risk-free rate (3) 2.47 % Expected term (in years) (4) 6.0 ____________ (1) Estimated using historical movement of Hilton's stock price. (2) Estimated based on the quarterly dividend and the three-month average stock price at the date of grant. (3) Based on the yields of U.S. Department of Treasury instruments with similar expected lives. (4) Estimated using the average of the vesting periods and the contractual term of the options. As of September 30, 2019, 1.5 million options were exercisable. Performance Shares During the nine months ended September 30, 2019, we granted 0.4 million performance shares with a weighted average grant date fair value per share of $83.11. The performance shares are settled at the end of the three-year performance period with: (i) 50 percent of the awards subject to achievement based on the compound annual growth rate ("CAGR") of the Company's earnings before interest expense, a provision for income taxes and depreciation and amortization ("EBITDA"), adjusted to exclude certain items ("Adjusted EBITDA"), referred to as EBITDA CAGR and (ii) 50 percent of the awards subject to achievement based on the Company’s free cash flow ("FCF") per share CAGR, referred to as FCF CAGR. The total number of performance shares that vest related to each performance measure is based on an achievement factor that ranges from a zero percent to 200 percent payout, with 100 percent being the target. As of September 30, 2019, we determined that the performance conditions for the performance shares are probable of achievement, and we recognized compensation expense, for both our outstanding EBITDA CAGR and FCF CAGR performance shares, at the maximum achievement percentage for the 2017 and 2018 performance shares and at target for the 2019 performance shares.

Segment Reporting [Abstract]
Business Segments	Business Segments We are a hospitality company with operations organized in two distinct operating segments: (i) management and franchise and (ii) ownership. These segments are managed and reported separately because of their distinct economic characteristics. The management and franchise segment includes all of the hotels we manage for third-party owners, as well as all franchised hotels operated or managed by someone other than us. As of September 30, 2019, this segment included 706 managed hotels and 5,154 franchised hotels consisting of 925,458 total rooms. This segment also earns licensing fees from Hilton Grand Vacations and co-brand credit card arrangements for the exclusive right to use certain Hilton marks and IP, as well as fees for managing properties in our ownership segment. As of September 30, 2019, the ownership segment included 65 properties totaling 20,481 rooms, comprising 57 hotels that we wholly owned or leased, one hotel owned by a consolidated non-wholly owned entity, two hotels leased by consolidated VIEs and five hotels owned or leased by unconsolidated affiliates. The performance of our operating segments is evaluated primarily on operating income, without allocating other revenues and expenses or general and administrative expenses.

Commitments and Contingencies

Commitments and Contingencies	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We provide performance guarantees to certain owners of hotels that we operate under management contracts. Most of these guarantees allow us to terminate the contract, rather than fund shortfalls, if specified operating performance levels are not achieved. However, in limited cases, we are obligated to fund performance shortfalls. As of September 30, 2019, we had six performance guarantees, with expirations ranging from December 2019 to 2039, and possible cash outlays totaling approximately $38 million. Our obligations under these guarantees in future periods are dependent on the operating performance level of the related hotel over the remaining term of the performance guarantee. As of September 30, 2019 and December 31, 2018, we accrued current liabilities of $3 million and $12 million, respectively, for one performance guarantee related to a hotel owned by a VIE for which we were not the primary beneficiary. We may enter into new contracts containing performance guarantees in the future, which could increase our possible cash outlays. We do not have any letters of credit pledged as collateral against our performance guarantees. As of September 30, 2019, we guaranteed two loans for three hotels that we franchise or will franchise for a total of $30 million. One of the loans has an initial maturity date in 2022 with two one-year extension options and the other loan will mature in 2023. Although we believe it is unlikely that material payments will be required under these guarantees, there can be no assurance that this will be the case. We do not have any letters of credit pledged as collateral against these guarantees. We hold interests in VIEs, for which we are not the primary beneficiary, that have entered into loan agreements with third parties. Under the terms of our contractual arrangements with certain of these VIEs, we may provide financial support to such entities under specified circumstances, including default of such a VIE under a third-party loan agreement, and may have the option to acquire a controlling financial interest in such an entity at a predetermined amount. In a circumstance that we provide financial support or exercise our option to acquire an additional interest in a VIE, we may be required to reassess whether we are the primary beneficiary of the VIE. If we determine that we are the primary beneficiary of the VIE, we would be required to consolidate the total assets, liabilities and results of operations of the VIE, which may be material upon consolidation. We have entered into agreements with owners of certain hotels that we currently manage or will franchise to finance capital expenditures at the hotels. As of September 30, 2019, we had remaining possible cash outlays of approximately $25 million, of which we expect to fund $15 million in the remainder of 2019 and $10 million in 2020. We receive fees from managed and franchised properties to operate our marketing, sales and brand programs on behalf of hotel owners. As of September 30, 2019 and December 31, 2018, we had collected an aggregate of $397 million and $375 million in excess of amounts expended, respectively, across all programs. We are involved in various claims and lawsuits arising in the ordinary course of business, some of which include claims for substantial sums. While the ultimate results of claims and litigation cannot be predicted with certainty, we expect that the

Condensed Consolidating Guarantor Financial Information [Abstract]
Condensed Consolidating Guarantor Financial Information	Condensed Consolidating Guarantor Financial Information Hilton Worldwide Finance LLC and Hilton Worldwide Finance Corp. (together, the "HWF Issuers"), which are 100 percent owned by Hilton Worldwide Parent LLC ("HWP"), which is 100 percent owned by the Parent, issued the 2025 Senior Notes and the 2027 Senior Notes. Hilton Domestic Operating Company Inc. ("HOC"), which is 100 percent owned by Hilton Worldwide Finance LLC, assumed the 2024 Senior Notes, issued the 2026 Senior Notes and, in June 2019, issued the 2030 Senior Notes. The 2024 Senior Notes, 2025 Senior Notes, 2026 Senior Notes, 2027 Senior Notes and 2030 Senior Notes are collectively referred to as the Senior Notes. The HWF Issuers and HOC are collectively referred to as the Subsidiary Issuers. The Senior Notes are guaranteed jointly and severally on a senior unsecured basis by HWP, the Parent and certain of the Parent's wholly owned domestic restricted subsidiaries that are themselves not issuers of the applicable series of Senior Notes (together, the "Guarantors''). The indentures that govern the Senior Notes provide that any subsidiary of the Company that provides a guarantee of our senior secured credit facilities will guarantee the Senior Notes. Additionally, the HWF Issuers are guarantors of the 2024 Senior Notes, the 2026 Senior Notes and the 2030 Senior Notes, and HOC is a guarantor of the 2025 Senior Notes and the 2027 Senior Notes. As of September 30, 2019, none of our foreign subsidiaries or U.S. subsidiaries owned by foreign subsidiaries or conducting foreign operations or our non-wholly owned subsidiaries guaranteed the Senior Notes (collectively, the "Non-Guarantors"). The guarantees are full and unconditional, subject to certain customary release provisions. The indentures that govern the Senior Notes provide that any Guarantor may be released from its guarantee so long as: (i) the subsidiary is sold or sells all of its assets; (ii) the subsidiary is released from its guaranty under our senior secured credit facilities; (iii) the subsidiary is declared "unrestricted" for covenant purposes; (iv) the subsidiary is merged with or into the applicable Subsidiary Issuers or another Guarantor or the Guarantor liquidates after transferring all of its assets to the applicable Subsidiary Issuers or another Guarantor; or (v) the requirements for legal defeasance or covenant defeasance or to discharge the indenture have been satisfied, in each case in compliance with applicable provisions of the indentures. The following tables present the condensed consolidating financial information as of September 30, 2019 and December 31, 2018, and for the three and nine months ended September 30, 2019 and 2018, for the Parent, HWF Issuers, HOC, Guarantors and Non-Guarantors. The condensed consolidating financial information presents the financial information for all periods based on the composition of the Guarantors and Non-Guarantors as of September 30, 2019.

Accounting Policies [Abstract]
Leases	Leases We determine if a contract is or contains a lease at the inception of the contract, and we classify that lease as a finance lease if it meets certain criteria or as an operating lease when it does not. We reassess if a contract is or contains a leasing arrangement upon modification of the contract. For a contract, in which we are a lessee, that contains fixed payments for both lease and non-lease components, we have elected to account for the components as a single lease component, as permitted. At the commencement date of a lease, we recognize a lease liability for future fixed lease payments and a right-of-use ("ROU") asset representing our right to use the underlying asset during the lease term. The lease liability is initially measured as the present value of the future fixed lease payments that will be made over the lease term. The lease term includes lessee options to extend the lease and periods occurring after a lessee early termination option, only to the extent it is reasonably certain that we will exercise such extension options and not exercise such early termination options, respectively. The future fixed lease payments are discounted using the rate implicit in the lease, if available, or our incremental borrowing rate. Our incremental borrowing rate is estimated on a portfolio basis and incorporates lease term, currency risk, credit risk and an adjustment for collateral. Upon adoption of ASU 2016-02, we elected to use the remaining lease term as of January 1, 2019 in our estimation of the applicable discount rate for leases that were in place at adoption. For the initial measurement of the lease liability for leases commencing after January 1, 2019, we use the discount rate as of the commencement date of the lease, incorporating the entire lease term. Additionally, we elected not to recognize leases with lease terms of 12 months or less at the commencement date in our consolidated balance sheets. Current maturities and long-term portions of operating lease liabilities are classified as accounts payable, accrued expenses and other and operating lease liabilities, respectively, and current maturities and long-term portions of finance lease liabilities are classified as current maturities of long-term debt and long-term debt, respectively, in our consolidated balance sheets. The ROU asset is measured at the amount of the lease liability with adjustments, if applicable, for lease prepayments made prior to or at lease commencement, initial direct costs incurred by us and lease incentives. We evaluate the carrying value of ROU assets if there are indicators of impairment and review the recoverability of the related asset group. If the carrying value of the asset group is determined to not be recoverable and is in excess of the estimated fair value, we record an impairment loss in our consolidated statements of operations. ROU assets of operating leases are classified as operating lease right-of-use assets and ROU assets of finance leases are classified as property and equipment, net in our consolidated balance sheets. Our operating leases require: (i) fixed lease payments, or minimum payments, as contractually stated in the lease agreement; (ii) variable lease payments, which, for our hotels, are generally based on a percentage of the underlying asset's revenues or profits, or are dependent on changes in an index; or (iii) lease payments equal to the greater of the fixed or variable lease payments. In addition, during the term of our hotel leases, we may be required to pay some, or all, of the capital costs for furniture, equipment and leasehold improvements in the hotel property. For operating leases, lease expense relating to fixed payments is recognized on a straight-line basis over the lease term, and lease expense related to variable payments is expensed as incurred, with amounts recognized in owned and leased hotel expenses, general and administrative expenses and other expenses from managed and franchised properties in our consolidated statements of operations. For finance leases, the amortization of the asset is recognized over the shorter of the lease term or useful life of the underlying asset within depreciation and amortization expense and other expenses from managed and franchised properties in our consolidated statements of operations. The interest expense related to finance leases, including any variable lease payments, is recognized in interest expense in our consolidated statements of operations.
New Accounting Pronouncements	Recently Issued Accounting Pronouncements In August 2018, the Financial Accounting Standards Board ("FASB") issued ASU No. 2018-15 ("ASU 2018-15"), Intangibles – Goodwill and Other – Internal-use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This ASU aligns guidance for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with guidance for capitalizing implementation costs to develop or obtain internal-use software. Capitalized implementation costs will be amortized over the term of the arrangement and presented in the same line item in the statement of operations as the fees associated with the service contract. We elected, as permitted by the standard, to early adopt ASU 2018-15 on a prospective basis as of January 1, 2019. The adoption did not have a material effect on our condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 , which supersedes existing guidance on accounting for leases in Leases (Topic 840) and generally requires all leases, including operating leases, to be recognized in the statement of financial position of lessees as ROU assets and lease liabilities, with certain practical expedients available. Subsequent to ASU 2016-02, the FASB issued related ASUs, including ASU No. 2018-11 ("ASU 2018-11"), Leases (Topic 842): Targeted Improvements, which provides for another transition method in addition to the modified retrospective approach required by ASU 2016-02. This option allows entities to initially apply the new leases standard at the adoption date and recognize a cumulative adjustment to the opening balance of retained earnings in the period of adoption. As described above, we adopted ASU 2016-02 on January 1, 2019 and applied the package of practical expedients included therein, as well as utilized the transition method included in ASU 2018-11. By applying ASU 2016-02 at the adoption date, as opposed to at the beginning of the earliest period presented, the presentation of financial information for periods prior to January 1, 2019 remain unchanged and in accordance with Leases (Topic 840) . On January 1, 2019, we recognized a $256 million cumulative adjustment to accumulated deficit, net of taxes of $81 million related to a decrease to our deferred tax liability, as a result of the impairment of ROU assets that occurred in periods prior to the adoption date.
