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, 2018 and 2017 have been prepared in accordance with United States of America ("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, 2017 . 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. On January 1, 2018, we adopted the requirements of Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09") using the full retrospective approach as of January 1, 2016. All amounts and disclosures set forth in this Form 10-Q reflect the necessary adjustments required for the adoption of this standard, including the reclassification of prior year balances to conform to current year presentation. See "Summary of Significant Accounting Policies" below for additional information. 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, 2017 . The significant accounting policies that changed as a result of the adoption of ASU 2014-09 are set forth below. Revenue Recognition Revenues are primarily derived from management and franchise contracts with third-party hotel and resort owners, as well as from our owned and leased hotels. The majority of our performance obligations are a series of distinct goods or services, for which we receive variable consideration through our management and franchise fees or fixed consideration through our owned and leased hotels. We allocate the variable fees to the distinct services to which they relate applying the prescribed variable consideration allocation guidance, and we allocate fixed consideration to the related performance obligations based on the present value of the allocated variable cash flows. We do not adjust the promised amount of consideration for the effects of a significant financing component when we expect, at contract inception, that the period between our transfer of a promised good or service to a customer and when the customer pays for that good or service will be one year or less, which it is in substantially all cases. Additionally, we do not typically include extended payment terms in our contracts with customers. Management and franchise revenues We identified the following performance obligations in connection with our management and franchise contracts: • Intellectual Property ("IP") licenses grant the right to access our hotel system IP, including brand IP, reservations systems and property management systems. • Hotel management services include providing day-to-day management services of the hotels for the property owners. • Development services include providing consultative services (e.g., design assistance and contractor selection) to the property owner to assist with the construction of the hotel prior to the hotel opening. • Pre-opening services include providing services (e.g., advertising, budgeting, e-commerce strategies, food and beverage testing) to the property owner to assist in preparing for the hotel opening. • Material rights for free or discounted goods or services to hotel guests are satisfied at the earlier point in time of either when the material right expires or the underlying free or discounted good or service is provided to the hotel guest. Each of the identified performance obligations related to management and franchise revenues is considered to be a series of distinct services transferred over time. While the underlying activities may vary from day to day, the nature of the promises are the same each day, and the property owner can independently benefit from each day's services. Management and franchise fees are typically based on the sales or usage of the underlying hotel, with the exception of fixed upfront fees, which usually represent an insignificant portion of the transaction price. Franchise fees represent fees earned in connection with the licensing of one of our brands, usually under long-term contracts with the property owner, and include the following: • Royalty fees are generally based on a percentage of the hotel's monthly gross room revenue and, in some cases, may also include a percentage of gross food and beverage revenues and other revenues, as applicable. These fees are typically billed and collected monthly, and revenue is generally recognized as services are provided. • Application, initiation and other fees are charged when: (i) new hotels enter our system; (ii) there is a change of ownership of a hotel; or (iii) contracts with properties already in our system are extended. These fees are typically fixed and collected upfront and are recognized as revenue over the term of the franchise contract. We do not consider this advance consideration to include a significant financing component, since it is used to protect us from the property owner failing to adequately complete some or all of its obligations under the contract. • License fees are earned from: (i) a license agreement with HGV to use certain Hilton marks and IP in its timeshare business, which are typically billed and collected monthly, and revenue is generally recognized at the same time the fees are billed; and (ii) co-brand credit card arrangements, which are recognized as revenue when points for our guest loyalty program, Hilton Honors, are issued, generally as spend on the co-branded credit card occurs; see further discussion below under "Hilton Honors." Consideration paid or anticipated to be paid to incentivize hotel owners to enter into franchise contracts with us is amortized over the life of the applicable contract as a reduction to franchise fees. Management fees represent fees earned from hotels that we manage, usually under long-term contracts with the property owner, and include the following: • Base management fees are generally based on a percentage of the hotel's monthly gross revenue. Base fees are typically billed and collected monthly, and revenue is generally recognized as services are provided. • Incentive management fees are generally based on a percentage of the hotel's operating profits and in some cases may be subject to a stated return threshold to the property owner, normally over a one-calendar year period (the "incentive period"). Incentive fee revenue is recognized on a monthly basis, but only to the extent the cumulative fee earned does not exceed the probable fee for the incentive period. Incentive fee payment terms vary, but they are generally billed and collected monthly or annually upon completion of the incentive period. Consideration paid or anticipated to be paid to incentivize hotel owners to enter into management contracts with us is amortized over the life of the applicable contract as a reduction to base and other management fees. Other revenues from managed and franchised properties represent amounts that are contractually reimbursed to us by property owners, either directly as costs are incurred or indirectly through fees that are billed and collected in advance related to certain costs and expenses of the related properties, and include the following: • Direct reimbursements include payroll and related costs and certain other operating costs of the managed and franchised properties' operations, which are contractually reimbursed to us by the property owners as expenses are incurred. Revenue is recognized based on the amount of expenses incurred by Hilton, which are presented as other expenses from managed and franchised properties in our consolidated statements of operations, that are then reimbursed to us by the property owner typically on a monthly basis, which results in no net effect on operating income (loss) or net income (loss). • Indirect reimbursements include marketing expenses and other expenses associated with our brands and shared services, which are paid from fees collected by Hilton from the managed and franchised properties. Indirect reimbursements are typically billed and collected monthly, based on the underlying hotel's sales or usage (e.g., gross room revenues and number of reservations processed), and revenue is generally recognized as services are provided. System implementation fees charged to property owners are deferred and recognized as revenue over the term of the management or franchise contract. The corresponding expenses are expensed as incurred and are presented as other expenses from managed and franchised properties in our consolidated statements of operations and are expected to equal the revenues earned from indirect reimbursements over time. The management and franchise fees and reimbursements from third-party hotel owners are allocated to the performance obligations and the distinct services to which they relate using their estimated standalone selling prices. The terms of the fees earned under the contract relate to a specific outcome of providing the services (e.g., hotel room sales) or to Hilton's efforts (e.g., costs) to satisfy the performance obligations. We use time as the measure of progress to recognize as revenue the fees that are allocated to the period earned per the contract or to the period when the reimbursable costs are incurred. Owned and leased hotel revenues We identified the following performance obligations in connection with our owned and leased hotel revenues, for which revenue is recognized as the respective performance obligations are satisfied, which results in recognizing the amount we expect to be entitled to for providing the goods or services: • Cancellable room reservations or ancillary services are typically satisfied as the good or service is transferred to the hotel guest, which is generally when the room stay occurs. • Noncancellable room reservations and banquet or conference reservations represent a series of distinct goods or services provided over time and satisfied as each distinct good or service is provided, which is reflected by the duration of the room reservation. • Material rights for free or discounted goods or services are satisfied at the earlier point in time when the material right expires or the underlying free or discounted good or service is provided to the hotel guest. • Other ancillary goods and services are purchased independently of the room reservation at standalone selling prices and are considered separate performance obligations, which are satisfied when the related good or service is provided to the hotel guest. • Components of package reservations for which each component could be sold separately to other hotel guests are considered separate performance obligations and are satisfied as set forth above. Owned and leased hotel revenues primarily consist of hotel room rentals, revenue from accommodations sold in conjunction with other services (e.g., package reservations), food and beverage sales and other ancillary goods and services (e.g., parking) related to owned, leased and consolidated non-wholly owned hotel properties. Revenue is recognized when rooms are occupied or goods and services have been delivered or rendered, respectively. Payment terms typically align with when the goods and services are provided. Owned and leased hotel revenues are reduced upon issuance of Hilton Honors points for Hilton Honors members' paid stay transactions and are recognized when Hilton Honors points are redeemed for a free stay at an owned or leased hotel (see the "Hilton Honors" section below for additional information). Although the transaction prices of room rentals, goods and other services are generally fixed and based on the respective room reservation or other agreement, an estimate to reduce the transaction price is required if a discount is expected to be provided to the customer. For package reservations, the transaction price is allocated to the performance obligations within the package based on the estimated standalone selling prices of each component. On occasion, the hotel may also provide the customer with a material right to a free or discounted good or service in conjunction with a room reservation or banquet contract (e.g., free breakfast and free room night for every four nights booked). These material rights are considered separate performance obligations to which a portion of the transaction price is allocated based on the estimated standalone selling prices of the good or service, adjusted for the likelihood the hotel guest will exercise the right. Other revenues Other revenues include revenues generated by the incidental support of hotel operations for owned, leased, managed and franchised hotels, including purchasing operations, and other operating income. Purchasing revenues include any amounts received for vendor rebate arrangements that we participate in as a manager of hotels. Taxes and fees collected on behalf of governmental agencies We are required to collect certain taxes and fees from customers on behalf of governmental agencies and remit these back to the applicable governmental agencies on a periodic basis. We have a legal obligation to act as a collection agent. We do not retain these taxes and fees and, therefore, they are not included in our measurement of transaction prices. We have elected to present revenue net of sales taxes and other similar taxes. We record a liability when the amounts are collected and relieve the liability when payments are made to the applicable taxing authority or other appropriate governmental agency. Contract Assets Contract assets relate to incentive management fees for which the period of service has passed, but for which our right to consideration is conditional upon completing the requirements of the incentive fee period. Contract assets are included in other current assets in our consolidated balance sheets and are reclassified as accounts receivable when our right to consideration becomes unconditional. Contract Liabilities Contract liabilities relate to: (i) advance consideration received from hotel owners at contract inception for services considered to be part of the contract performance obligations, such as application, initiation and other fees; (ii) advance consideration received for certain indirect reimbursements, such as system implementation fees; and (iii) amounts received when points are issued under Hilton Honors, but for which revenue is not yet recognized, since the related points are not yet redeemed. Contract liabilities related to advance consideration received for fees and certain indirect reimbursements are recognized as revenue over the term of the related contract. Contract liabilities related to amounts received for Hilton Honors are recognized as revenue when the points are redeemed for a free good or service by the Hilton Honors member, which, on average, occurs within two years of points issuance. Contract liabilities are included in deferred revenues in our consolidated balance sheets. Intangible Assets with Finite Useful Lives We have certain finite lived intangible assets that were initially recorded at their fair value in connection with the October 24, 2007 transaction whereby we became a wholly owned subsidiary of affiliates of The Blackstone Group L.P. ("Blackstone") (the "Merger"). These intangible assets consist of management contracts, franchise contracts, leases, certain proprietary technologies and our Hilton Honors guest loyalty program. Additionally, we capitalize cash consideration paid to incentivize hotel owners to enter into management and franchise contracts with us as contract acquisition costs and the incremental costs to obtain or fulfill the contracts as development commissions, which are generally fixed. We also capitalize costs incurred to develop internal-use computer software and costs to acquire software licenses, as well as internal and external costs incurred in connection with the development of upgrades or enhancements that result in additional information technology functionality. Intangible assets with finite useful lives are amortized using the straight-line method over their respective estimated useful lives, which for contract acquisition costs and development commissions is the contract term, including any renewal periods that are at our sole option. These estimated useful lives are generally as follows: management contracts recorded at the Merger ( 13 to 16 years); management contract acquisition costs and development commissions ( 20 to 30 years); franchise contracts recorded at the Merger ( 12 to 13 years); franchise contract acquisition costs and development commissions ( 10 to 20 years); leases ( 12 to 35 years); Hilton Honors ( 16 years); and capitalized software development costs ( 3 years). In our consolidated statements of operations, the amortization of these intangible assets, excluding contract acquisition costs, is included in depreciation and amortization expense, and the amortization of contract acquisition costs is recognized as a reduction to franchise fees and base and other management fees, based on contract type. Costs incurred prior to the acquisition of a contract, such as external legal costs, are expensed as incurred and included in general and administrative expenses in our consolidated statements of operations. Cash flows for contract acquisition costs and development commissions are included as operating activities in our consolidated statements of cash flows. We review all finite lived intangible assets for impairment when circumstances indicate that their carrying values may not be recoverable. If the carrying value of an asset group is not recoverable, we recognize an impairment loss for the excess carrying value over the fair value in our consolidated statements of operations. Hilton Honors Hilton Honors is our guest loyalty and marketing program provided to our hotel and resort properties. Nearly all of our owned, leased, managed and franchised properties participate in the Hilton Honors program. Hilton Honors members earn points based on their spending at our participating properties and through participation in affiliated partner programs. When points are earned by Hilton Honors members, they are provided with a material right to free or discounted goods or services in the future upon accumulation of the required level of Hilton Honors points. Points may be redeemed for the right to stay at participating properties, as well as for other goods and services from third parties, including, but not limited to, airlines, car rentals, cruises, vacation packages, shopping and dining. As points are issued to a Hilton Honors member, the property or program partner pays Hilton Honors based on an estimated cost per point for the costs of operating the program, which include marketing, promotion, communication and administrative expenses, as well as the estimated cost of award redemptions. When these payments are received we record amounts equal to the estimated cost per point of the future redemption obligation within the liability for guest loyalty program and any amounts received in excess of the estimated cost per point within deferred revenues in our consolidated balance sheets. We engage outside actuaries to assist in determining the fair value of the future redemption obligation using statistical formulas that project future point redemptions based on factors that include historical experience, an estimate of points that will eventually be redeemed, which includes an estimate of "breakage" for points that will never be redeemed, and the cost of reimbursing properties and other third parties with respect to other redemption opportunities available to Hilton Honors members. When points are issued as a result of a stay at an owned or leased hotel, we recognize a reduction in owned and leased hotel revenues, since we are also the guest loyalty program sponsor. For the Hilton Honors fees that are charged to the participating properties, we allocate the fees to the material right created by the Hilton Honors points that are issued using the variable consideration allocation guidance, since the fees are directly related to the issuance of Hilton Honors points to the Hilton Honors member and Hilton's efforts to satisfy the future redemption of those Hilton Honors points. The transaction prices for the Hilton Honors points are reduced by the expected payments to the third parties that will provide the free or discounted room or service using the actuarial projection of the cost per point. The remaining transaction price is then further allocated to the points that are expected to be redeemed, adjusting the points that are issued for estimated breakage, and recognized when those points are redeemed. While the points are outstanding, both the estimate of the expected payments to third parties (cost per point) and the estimated breakage are reevaluated, and the amount of revenue recognized when each point is redeemed is adjusted so that the final amount allocated to the material right is reflective of the amount retained for providing the free or discounted goods and services, net of the payments to third parties and points not redeemed. We also earn license fees from co-brand credit card arrangements (see "Management and franchise revenues" within the "Revenue Recognition" section above). The co-brand license fee is allocated between two performance obligations based on their estimated standalone selling prices: (i) an IP license using the relief-from-royalty method; and (ii) material rights for free or discounted goods or services to the credit card customers using a cost plus method based on an evaluation of other third-party administrators. We satisfy our performance obligation related to points issued under Hilton Honors when points are redeemed for a free good or service by the Hilton Honors member, and we satisfy our remaining performance obligations over time as the customer simultaneously receives and consumes the benefits of the goods or services provided. Hilton Honors reimburses participating properties and applicable third parties when points are redeemed by members, at which time the redemption obligation is reduced and the related deferred revenue is recognized in other revenues from managed and franchised properties in our consolidated statements of operations. Additionally, when Hilton Honors members redeem award certificates at our owned and leased hotels, we recognize room revenue, included in owned and leased hotel revenues in our consolidated statements of operations. Recently Issued Accounting Pronouncements Adopted Accounting Standards In March 2017, the Financial Accounting Standards Board ("FASB") issued ASU No. 2017-07 ("ASU 2017-07"), Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . This ASU requires employers to report the service cost component of net periodic pension cost in the same line item or items of the statement of operations as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net periodic pension cost must be presented separately from the service cost component and outside of a subtotal of income (loss) from operations. We adopted ASU 2017-07 on January 1, 2018 on a retrospective basis in our condensed consolidated statements of operations, which includes presenting: (i) the service cost component of net periodic pension cost in owned and leased hotel expenses and general and administrative expenses; and (ii) the other components of net periodic pension cost in other non-operating income (loss), net in our condensed consolidated statements of operations. Prior to adoption, all net periodic pension costs were presented in owned and leased hotel expenses and general and administrative expenses. We have applied the practical expedient permitting us to use the amounts disclosed in our "Employee Benefits Plans" note in our Annual Report on Form 10-K for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. See the "Prior Period Financial Information" below for the effect of the adoption of ASU 2017-07 on our condensed consolidated statements of operations for the three and nine months ended September 30, 2017 . In May 2014, the FASB issued ASU 2014-09. This ASU supersedes the revenue recognition requirements in Revenue Recognition (Topic 605) and requires entities to recognize revenue when a customer obtains control of promised goods or services and in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. Subsequent to ASU 2014-09, the FASB issued several related ASUs to clarify the application of the new revenue recognition standard, collectively referred to herein as ASU 2014-09. We adopted the requirements of ASU 2014-09 on January 1, 2018 using the full retrospective approach, as permitted by the standard, resulting in a cumulative adjustment to accumulated deficit of $212 million as of January 1, 2016. The provisions of ASU 2014-09 affected our revenue recognition as follows: • Application, initiation and other fees are recognized over the term of the franchise contract, rather than upon execution of the contract and the unamortized portion of these fees is included in deferred revenues in our consolidated balance sheets. • Contract acquisition costs related to our management and franchise contracts are recognized over the term of the contracts as a reduction to revenue, instead of as amortization expense. This change does not affect net income (loss). • Incentive management fees are recognized to the extent that it is probable that a significant reversal will not occur as a result of future hotel profits or cash flows, as opposed to recognizing amounts that would be due if the management contract was terminated at the end of the reporting period. This change does not affect net income (loss) for any full year period. • Revenue related to our Hilton Honors guest loyalty program is recognized upon point redemption, net of any reward reimbursement paid to a third party, as opposed to recognized on a gross basis at the time points are issued in conjunction with the accrual of the expected future cost of the reward reimbursement. Additionally, points issued at owned and leased hotels are accounted for as a reduction of owned and leased hotel revenues, as opposed to owned and leased hotel expenses. Fees received in excess of the estimated liability for guest loyalty program are included in deferred revenues in our consolidated balance sheets. • Reimbursable fees related to our management and franchise contracts are recognized as they are billed, as opposed to when we incur the related expenses. Timing differences related to the receipt and spend of these fees will no longer be recorded in other assets and other liabilities in our consolidated balance sheets. We have not retrospectively restated for contract modifications of management and franchise contracts that occurred before January 1, 2016. Instead, we have reflected the aggregate effect of all contract modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price. The estimated effect of applying this practical expedient is to use a longer period over which to straight line any fixed consideration either received from the customer or paid to the customer, since all fees will be amortized over the full contract term beginning on the date of initial execution, rather than amortizing fees received upon contract modifications prospectively from the contract modification date. We do not anticipate that this effect is material given the insignificance of the fixed consideration compared to the overall consideration we expect to earn over the term of the contract. See the "Prior Period Financial Information" below for the effect of the adoption of ASU 2014-09 on our condensed consolidated balance sheet as of December 31, 2017 and our condensed consolidated statements of operations for the three and nine months ended September 30, 2017 .

Revenue from Contract with Customer [Abstract]
Revenues from Contracts with Customers	Revenues from Contracts with Customers Contract Liabilities Our contract liabilities, which are classified as a component of current and long-term deferred revenues, decreased $34 million during the nine months ended September 30, 2018 , from $1,087 million as of December 31, 2017 to $1,053 million as of September 30, 2018 . The change included a $167 million decrease, which had no effect on revenues, resulting from changes in estimated transaction prices for our performance obligations related to points issued under Hilton Honors. This decrease was partially offset by a $135 million net increase from cash received in advance, for which revenue recognition was deferred, and revenue recognized during the period, mostly related to Hilton Honors. We recognized revenues that were previously deferred as contract liabilities of $33 million and $31 million during the three months ended September 30, 2018 and 2017 , respectively, and $149 million and $105 million during the nine months ended September 30, 2018 and 2017 , respectively. Performance Obligations As of September 30, 2018 , we had $478 million of deferred revenues related to unsatisfied performance obligations under Hilton Honors that will be recognized as revenues when the points are redeemed, which is expected to occur over the next two years . Additionally, we had $575 million of deferred revenues related to application, initiation and other fees, which are expected to be recognized as revenues in future periods over the terms of the related contracts. We did not estimate revenues expected to be recognized related to our unsatisfied performance obligations for our: (i) royalty fees, since they are considered sales-based royalty fees recognized as hotel room sales occur in exchange for licenses of our brand names over the terms of the franchise contracts; and (ii) base management fees and incentive management fees, since they are allocated entirely to the wholly unsatisfied promise to transfer management services, which form part of a single performance obligation in a series, over the term of the individual management contract. As part of the adoption of ASU 2014-09, we elected not to disclose the amount of the transaction price allocated to our remaining performance obligations as of December 31, 2017 or provide an explanation of when we expect to recognize that amount as revenue.

Consolidated Variable Interest Entities	Consolidated Variable Interest Entities As of September 30, 2018 and December 31, 2017 , we consolidated three variable interest entities ("VIEs"): two entities that lease hotel properties and one management company. We are the primary beneficiaries of these consolidated VIEs as we have 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. Our condensed consolidated balance sheets included the assets and liabilities of these entities, which primarily comprised the following: September 30, December 31, 2018 2017 (in millions) Cash and cash equivalents $ 66 $ 73 Accounts receivable, net 11 16 Property and equipment, net 67 57 Deferred income tax assets 56 56 Other non-current assets 58 57 Accounts payable, accrued expenses and other 41 43 Long-term debt (1) 202 212 Other long-term liabilities 13 13 ____________ (1) Includes capital lease obligations of $186 million and $191 million as of September 30, 2018 and December 31, 2017 , respectively. During the nine months ended September 30, 2018 and 2017 , we did not provide any financial or other support to any VIEs that we were not previously contractually required to provide, nor do we intend to provide such support in the future.

Senior Notes In April 2018, we issued $1.5 billion aggregate principal amount of 5.125% Senior Notes due 2026 (the "2026 Senior Notes"), and incurred $21 million of debt issuance costs. Interest on the 2026 Senior Notes is payable semi-annually in arrears on May 1 and November 1 of each year, beginning November 2018. We used a portion of the net proceeds from the issuance of the 2026 Senior Notes, together with borrowings under our senior secured revolving credit facility (the "Revolving Credit Facility") and available cash, to repurchase 16.5 million shares of our common stock from a former stockholder for $1,171 million and repay $500 million outstanding under our senior secured term loan facility (the "Term Loans"). See "Senior Secured Credit Facility" below for additional information. In March 2017, we used the proceeds from issuances of the 4.625% Senior Notes due 2025 (the "2025 Senior Notes") and the 4.875% Senior Notes due 2027 (the "2027 Senior Notes") to redeem in full $1.5 billion of Senior Notes due 2021 (the "2021 Senior Notes"). In connection with the repayment, we paid a redemption premium of $42 million and accelerated the recognition of $18 million of unamortized deferred financing costs, which were included in loss on debt extinguishment in our condensed consolidated statement of operations for the nine months ended September 30, 2017 . The 4.250% Senior Notes due 2024 (the "2024 Senior Notes"), the 2025 Senior Notes, the 2026 Senior Notes and the 2027 Senior Notes are guaranteed on a senior unsecured basis by the Parent and substantially all of its direct and indirect wholly owned domestic subsidiaries. See Note 15 : " Condensed Consolidating Guarantor Financial Information " for additional details. Senior Secured Credit Facility Our senior secured credit facility consists of a $1.0 billion Revolving Credit Facility and the Term Loans. The obligations of our senior secured credit facility are unconditionally and irrevocably guaranteed by the Parent and substantially all of its direct and indirect wholly owned domestic subsidiaries. During the nine months ended September 30, 2018, we borrowed $150 million under the Revolving Credit Facility and all amounts borrowed were repaid in the same period. In connection with the $500 million repayment of the Term Loans in April 2018, we accelerated the recognition of $5 million of 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, 2018 . Additionally, the interest rate on the remaining balance of the Term Loans was reduced by 25 basis points to LIBOR plus 175 basis points . As of September 30, 2018 , we had $64 million of letters of credit outstanding under our Revolving Credit Facility and a borrowing capacity of $936 million .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities Cash Flow Hedges In May 2017, we began hedging foreign exchange-based cash flow variability in certain of our foreign currency denominated management and franchise fees using forward contracts (the "Fee Forward Contracts"). We elected to designate these Fee Forward Contracts as cash flow hedges for accounting purposes. As of September 30, 2018 , the Fee Forward Contracts had an aggregate notional amount of $73 million and maturities of 24 months or less. In March 2017, we entered into two interest rate swap agreements with notional amounts of $1.6 billion and $750 million to swap one-month LIBOR on the Term Loans to fixed rates of 1.98 percent and 2.02 percent, respectively, through March 2022 . In May 2018, we settled the interest rate swap with a notional amount of $750 million and received $18 million from the counterparty. Concurrently, we entered into an interest rate swap agreement with a notional amount of $1.6 billion , which swaps one-month LIBOR on the Term Loans to a fixed rate of 3.03 percent, for a term from March 2022 to March 2023 . We elected to designate these interest rate swaps as cash flow hedges for accounting purposes. Non-designated Hedges As of September 30, 2018 , we held short-term forward contracts with an aggregate notional amount of $383 million to offset exposure to fluctuations in certain of our foreign currency denominated cash balances. We elected not to designate these forwar d contracts as hedging instruments. Depending on the fair value of each contract, we classify it as an asset or liability. Fair Value of Derivative Instruments We measure our derivative instruments at fair value, which is estimated using a discounted cash flow analysis, and we consider the inputs used to measure the fair value as Level 2 within the fair value hierarchy. The discounted cash flow analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs of similar instruments, including interest rate curves and spot and forward rates, as applicable, as well as option volatility. The fair values of our derivative instruments in our condensed consolidated balance sheets were as follows: September 30, December 31, Balance Sheet Classification 2018 2017 (in millions) Cash Flow Hedges: Interest rate swaps Other non-current assets $ 48 $ 11 Forward contracts Other current assets 1 — Forward contracts Accounts payable, accrued expenses and other — 1 Non-designated Hedges: Forward contracts Other current assets 1 4 Forward contracts Accounts payable, accrued expenses and other 2 1 Earnings Effect of Derivative Instruments The gains and losses recognized in our condensed consolidated statements of operations and condensed consolidated statements of comprehensive income before any effect for income taxes were as follows: Three Months Ended Nine Months Ended September 30, September 30, Classification of Gain (Loss) Recognized 2018 2017 2018 2017 (in millions) Cash Flow Hedges (1) : Interest rate swaps Other comprehensive income (loss) $ 8 $ (2 ) $ 53 $ (26 ) Interest rate swaps (2) Interest expense — (5 ) (2 ) (13 ) Forward contracts (3) Other comprehensive income (loss) (1 ) (1 ) 2 (1 ) Non-designated Hedges: Interest rate swaps Other non-operating income, net N/A — N/A 2 Interest rate swaps (4) Interest expense (1 ) (3 ) (6 ) (8 ) Forward contracts Gain (loss) on foreign currency transactions (2 ) 3 (8 ) 10 ____________ (1) There were no amounts recognized in earnings related to hedge ineffectiveness or amounts excluded from hedge effectiveness testing during the three and nine months ended September 30, 2018 and 2017 .

The carrying values and fair values exclude capital lease obligations and other debt. The fair values of financial instruments not included in these tables are estimated to be equal to their carrying values as of September 30, 2018 and December 31, 2017 . Our estimates of the fair values were determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop the estimated fair values. Cash equivalents and restricted cash equivalents primarily consisted of short-term interest-bearing money market funds and commercial paper with maturities of less than 90 days, and time deposits. The estimated fair values were based on available market pricing information of similar financial instruments. The estimated fair values of our Level 1 long-term debt were based on prices in active debt markets. The estimated fair values of our Level 3 long-term debt were based on indicative quotes received for similar issuances.

Income Tax Disclosure [Abstract]
Income taxes	Income Taxes Restructuring During September of 2018, one of our controlled foreign corporations ("CFC") distributed the stock of a subsidiary that owned multiple other subsidiaries (the "September Distribution"). The distributed subsidiaries will now be includible in our U.S. federal and state income tax filings. As a result of the September Distribution, we incurred deferred income tax expense of $29 million , including: (i) U.S. deferred tax liabilities related to the distributed subsidiaries of $32 million ; and (ii) remeasuring our existing deferred tax assets and liabilities and other tax liabilities at the effective tax rates at which they will reverse in future periods, resulting in a reduction of liabilities of $3 million . Tax Cuts and Jobs Act of 2017 On December 22, 2017, the TCJ Act, which permanently reduces the federal corporate income tax rate from a graduated 35 percent to a flat 21 percent rate and imposes a one-time transition tax on earnings of foreign subsidiaries that were previously deferred, was signed into law. As of September 30, 2018 , we had not completed our accounting for the tax effects of enactment of the TCJ Act; however, as described below, we made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. We recognized a provisional benefit at December 31, 2017 of $665 million , of which $517 million was the result of the remeasurement of U.S. deferred tax assets and other tax liabilities. The provisional benefit of $517 million recorded at December 31, 2017 on our existing deferred tax balances excludes the income tax impact of the adoption of ASU 2014-09. As of September 30, 2018 , we made adjustments to the provisional amounts recorded at December 31, 2017 , as described below. Provisional Amounts • Deferred tax assets and liabilities and other tax liabilities. We remeasured deferred tax assets and liabilities and other tax liabilities based on the rates at which they are expected to reverse in the future, which is generally 21 percent . The provisional amounts recorded at December 31, 2017 related to the remeasurement of our deferred tax assets and liabilities, uncertain tax position reserves, and other tax liabilities were income tax benefits of $517 million , $33 million and $84 million , respectively. However, this remeasurement was based on estimates as of the enactment date of the TCJ Act and our existing analysis of the numerous complex tax law changes in the TCJ Act. Upon refinement of our calculations, we adjusted our provisional amount by recording additional tax benefits of $2 million and $10 million , during the three and nine months ended September 30, 2018, respectively, which are included as components of income tax expense. We will continue to analyze the tax law changes in the TCJ Act, including the impact on our 2017 tax return filing positions throughout the 2018 fiscal year, and update our provisional amounts related to the remeasurement of these balances. • Foreign taxation changes. A one-time transition tax is applied to foreign earnings previously not subjected to U.S. tax. The one-time transition tax is based on our total post-1986 earnings and profits ("E&P") that were previously deferred from U.S. income taxes, but is assessed at a lower tax rate than the federal corporate tax rate of 35 percent . We recorded a provisional amount for our one-time transition tax liability for our foreign subsidiaries based on estimates, as of the enactment date of the TCJ Act, for our controlled foreign subsidiaries and estimates of the total post-1986 E&P for noncontrolled foreign subsidiaries. We previously recorded a federal deferred tax liability for our deferred earnings at the statutory 35 percent rate. The application of the transition tax results in the deferred earnings previously recorded at 35 percent being subjected to a lower rate, resulting in a provisional income tax benefit at December 31, 2017 of $15 million . As a result of additional guidance issued by the U.S. Treasury Department, we refined our calculations and recorded additional tax expense of $1 million and tax benefit of $2 million during the three and nine months ended September 30, 2018, respectively. Additionally, we had not recorded certain deferred tax assets, related primarily to E&P deficits, for some foreign subsidiaries based upon an expectation that no tax benefit from such assets would be realized within the foreseeable future. The recognition of tax benefits from the deferred tax assets previously not recorded resulted in a provisional income tax benefit at December 31, 2017 of $16 million . We will continue to update our provisional amounts related to the transition tax as the U.S. Treasury Department provides further guidance. With the changes made to the U.S. taxation of foreign entities, including the change to a territorial system of taxation, the introduction of a dividend participation exemption and the changes to the current taxation of global intangible low-taxed income ("GILTI"), we determined our current method of calculating CFC outside basis should be revised to incorporate the TCJ Act changes. As of September 30, 2018, we were able to determine a reasonable estimate of the TCJ Act’s effects on our recognition of deferred tax assets and liabilities for outside basis differences in our investments in foreign subsidiaries. As permitted, we recorded provisional deferred tax liabilities of $31 million for the three and nine months ended September 30, 2018 within income tax expense in our condensed consolidated statements of operations. We will further analyze the impact of the TCJ Act on foreign earnings and on our tax positions throughout fiscal year 2018 as the U.S. Treasury Department provides further guidance to allow us to complete the required accounting for our outside basis differences in our investments in foreign subsidiaries. GILTI and Foreign Derived Intangible Income ("FDII") The TCJ Act subjects a U.S. stockholder to current tax on GILTI earned by certain foreign subsidiaries. In addition, the TCJ Act provides for FDII to be taxed at a lower effective rate than the statutory rate by allowing a tax deduction against the income. Interpretive guidance on the accounting for GILTI states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred as a period expense only. As of September 30, 2018, we have elected to recognize the current tax on GILTI as a period expense in the period the tax is incurred. We have included the current tax impact of both GILTI and the FDII deduction in our estimated annual effective tax rate as of September 30, 2018. Income Tax Provision 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 pre-tax income or loss, which is subject to federal, state, local and foreign income taxes. The September Distribution increased our effective tax rate above the statutory tax rate by 10 percent percent and 4 percent for the three and nine months ended September 30, 2018, respectively. Additionally, updates to our provisional amounts related to the TCJ Act increased our effective tax rate above the statutory rate by 10 percent and 2 percent for the three and nine months ended September 30, 2018, respectively. Our total unrecognized tax benefits as of September 30, 2018 and December 31, 2017 were $311 million and $283 million , respectively. We have also accrued a cumulative total of approximately $39 million and $33 million for the payment of interest and penalties as of September 30, 2018 and December 31, 2017 , respectively. Included in the balances of unrecognized tax benefits as of September 30, 2018 and December 31, 2017 were $307 million and $285 million , respectively, associated with positions that, if favorably resolved, would provide a benefit to our effective income tax rate. During the three and nine months ended September 30, 2018, we increased our reserve for tax uncertainties by $26 million and $28 million , respectively, for positions that we determined were not more likely than not to receive a full benefit upon audit. In April 2014, we received 30-day Letters from the Internal Revenue Service ("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 our Hilton Honors guest loyalty program, 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, and thus foreign currency gains and losses with respect to such loans should have been measured in euros, 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 2006 through October 2007. 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 foreign currency gains and losses 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 IRS Appeals 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 2006 through October 2007. The adjustments for tax years 2011 through 2013 will also be protested in appeals and formal protests will be submitted during the fourth quarter of 2018. After receipt of the TAM relating to the Luxembourg subsidiary, in total, 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 taxes. The portion of this amount related to Hilton Honors would result in a decrease to our future tax liability when the points are redeemed. We disagree with the IRS's position on each of these assertions and intend to vigorously contest them. However, based on continuing appeals process discussions with the IRS, we believe that it is more likely than not that we will not recognize the full benefit related to certain of the issues being appealed. Accordingly, we have recorded $50 million of unrecognized tax benefits related to these issues. 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 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. We are no longer subject to U.S. federal income tax examination for years through 2004. As of September 30, 2018 , we remain subject to federal examinations from 2005 through 2017, state examinations from 2005 through 2017 and foreign examinations of our income tax returns for the years 1996 through 2017.

Disclosure of Compensation Related Costs, Share-based Payments [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 restricted stock units and restricted stock (collectively, "performance shares") to our employees and deferred share units ("DSUs") to members of our board of directors. We recognized share-based compensation expense of $35 million and $32 million during the three months ended September 30, 2018 and 2017 , respectively, and $103 million and $91 million during the nine months ended September 30, 2018 and 2017 , respectively. As of September 30, 2018 , unrecognized compensation costs for unvested awards was approximately $151 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, 2018 , there were 16.1 million shares of common stock available for future issuance under our 2017 Omnibus Incentive Plan, plus any shares subject to awards outstanding under our 2013 Omnibus Incentive Plan, which will become available for issuance under our 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, 2018 , we granted 0.9 million RSUs with a weighted average grant date fair value per share of $79.31 , which generally vest in equal annual installments over two or three years from the date of grant. Options During the nine months ended September 30, 2018 , we granted 0.6 million options with a weighted average exercise price per share of $79.36 , 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, 2018 was $23.72 , which was determined using the Black-Scholes-Merton option-pricing model with the following assumptions: Expected volatility (1) 27.91 % Dividend yield (2) 0.74 % Risk-free rate (3) 2.73 % 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, 2018 , 1.2 million options were exercisable. Performance Shares During the nine months ended September 30, 2018 , we granted 0.3 million performance shares with a weighted average grant date fair value per share of $79.36 . The performance shares are settled at the end of the three-year performance period with 50 percent of the awards subject to achievement based on the compound annual growth rate ("CAGR") of the Company's adjusted earnings before interest expense, a provision for income taxes and depreciation and amortization ("Adjusted EBITDA"), referred to as EBITDA CAGR, and the other 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. We determined that the performance conditions for performance shares issued in 2018 and 2017 are probable of achievement and, as of September 30, 2018 , we recognized compensation expense based on the following anticipated achievement percentages for these performance shares: EBITDA CAGR FCF CAGR 2017 performance shares 200 % 200 % 2018 performance shares 150 % 150 %

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, 2018 , this segment included 670 managed hotels and 4,768 franchised hotels consisting of 864,071 total rooms. This segment also earns license fees from HGV and co-brand credit card arrangements, as well as fees for managing properties in our ownership segment. As of September 30, 2018 , the ownership segment included 71 properties totaling 21,720 rooms, comprising 62 hotels that we wholly owned or leased, one hotel owned by a consolidated non-wholly owned entity, two hotels leased by consolidated VIEs and six hotels owned or leased by unconsolidated affiliates. The performance of our operating segments is evaluated primarily on operating income, without allocating corporate and other revenues and expenses or general and administrative expenses. The following table presents revenues for our reportable segments, reconciled to consolidated amounts: Three Months Ended Nine Months Ended September 30, September 30, 2018 2017 2018 2017 (in millions) Franchise fees $ 409 $ 359 $ 1,147 $ 998 Base and other management fees (1) 95 99 286 284 Incentive management fees 57 53 171 159 Management and franchise 561 511 1,604 1,441 Ownership 373 383 1,099 1,052 Segment revenues 934 894 2,703 2,493 Amortization of contract acquisition costs (6 ) (4 ) (20 ) (12 ) Other revenues 27 21 72 78 Direct reimbursements from managed and franchised properties 710 626 2,139 1,925 Indirect reimbursements from managed and franchised properties 599 566 1,754 1,608 Intersegment fees elimination (1) (11 ) (12 ) (30 ) (29 ) Total revenues $ 2,253 $ 2,091 $ 6,618 $ 6,063 ____________ (1) Includes management, royalty and IP fees charged to our ownership segment by our management and franchise segment, which were eliminated in our condensed consolidated statements of operations.

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. We may enter into new contracts containing performance guarantees in the future, which could increase our possible cash outlays. As of September 30, 2018 , we had four performance guarantees, with expirations ranging from 2019 to 2030 , and possible cash outlays totaling approximately $44 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. We do not have any letters of credit pledged as collateral against these guarantees. As of September 30, 2018 and December 31, 2017 , we recorded $10 million and $12 million , respectively, in accounts payable, accrued expenses and other and $2 million and $9 million , respectively, in other liabilities in our condensed consolidated balance sheets for one and two outstanding performance guarantees, respectively, that are related to VIEs for which we are not the primary beneficiary. We receive fees from managed and franchised properties to operate our marketing, sales and brand programs on behalf of hotel and resort owners. As of September 30, 2018 and December 31, 2017 , we had collected an aggregate of $401 million and $402 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 ultimate resolution of all pending or threatened claims and litigation as of September 30, 2018 will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Condensed Consolidating Guarantor Financial Information [Abstract]
Condensed Consolidating Guarantor Financial Information	Condensed Consolidating Guarantor Financial Information In April 2018, Hilton Domestic Operating Company Inc. ("HOC"), which is 100 percent owned by Hilton Worldwide Finance LLC, issued the 2026 Senior Notes. In March 2017, Hilton Worldwide Finance LLC and Hilton Worldwide Finance Corp. (the "HWF Issuers"), entities that are 100 percent owned by Hilton Worldwide Parent LLC ("HWP"), which is 100 percent owned by the Parent, issued the 2025 Senior Notes and 2027 Senior Notes. In September 2016, HOC assumed the 2024 Senior Notes that were issued in August 2016 by escrow issuers. The HWF Issuers are guarantors of the 2026 Senior Notes and the 2024 Senior Notes. HOC is a guarantor of the 2025 Senior Notes and the 2027 Senior Notes. The 2024 Senior Notes, 2025 Senior Notes, 2026 Senior Notes and 2027 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 100 percent 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 facility will guarantee the Senior Notes. As of September 30, 2018 , none of our foreign subsidiaries or U.S. subsidiaries owned by foreign subsidiaries or conducting foreign operations or our non-wholly owned subsidiaries guarantee the Senior Notes (collectively, the "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, 2018 . 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 facility; (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, 2018 and December 31, 2017 , and for the three and nine months ended September 30, 2018 and 2017 , for the Parent, HWF Issuers, HOC, Guarantors and Non-Guarantors.

Accounting Policies [Abstract]
Revenue Recognition	Revenue Recognition Revenues are primarily derived from management and franchise contracts with third-party hotel and resort owners, as well as from our owned and leased hotels. The majority of our performance obligations are a series of distinct goods or services, for which we receive variable consideration through our management and franchise fees or fixed consideration through our owned and leased hotels. We allocate the variable fees to the distinct services to which they relate applying the prescribed variable consideration allocation guidance, and we allocate fixed consideration to the related performance obligations based on the present value of the allocated variable cash flows. We do not adjust the promised amount of consideration for the effects of a significant financing component when we expect, at contract inception, that the period between our transfer of a promised good or service to a customer and when the customer pays for that good or service will be one year or less, which it is in substantially all cases. Additionally, we do not typically include extended payment terms in our contracts with customers. Management and franchise revenues We identified the following performance obligations in connection with our management and franchise contracts: • Intellectual Property ("IP") licenses grant the right to access our hotel system IP, including brand IP, reservations systems and property management systems. • Hotel management services include providing day-to-day management services of the hotels for the property owners. • Development services include providing consultative services (e.g., design assistance and contractor selection) to the property owner to assist with the construction of the hotel prior to the hotel opening. • Pre-opening services include providing services (e.g., advertising, budgeting, e-commerce strategies, food and beverage testing) to the property owner to assist in preparing for the hotel opening. • Material rights for free or discounted goods or services to hotel guests are satisfied at the earlier point in time of either when the material right expires or the underlying free or discounted good or service is provided to the hotel guest. Each of the identified performance obligations related to management and franchise revenues is considered to be a series of distinct services transferred over time. While the underlying activities may vary from day to day, the nature of the promises are the same each day, and the property owner can independently benefit from each day's services. Management and franchise fees are typically based on the sales or usage of the underlying hotel, with the exception of fixed upfront fees, which usually represent an insignificant portion of the transaction price. Franchise fees represent fees earned in connection with the licensing of one of our brands, usually under long-term contracts with the property owner, and include the following: • Royalty fees are generally based on a percentage of the hotel's monthly gross room revenue and, in some cases, may also include a percentage of gross food and beverage revenues and other revenues, as applicable. These fees are typically billed and collected monthly, and revenue is generally recognized as services are provided. • Application, initiation and other fees are charged when: (i) new hotels enter our system; (ii) there is a change of ownership of a hotel; or (iii) contracts with properties already in our system are extended. These fees are typically fixed and collected upfront and are recognized as revenue over the term of the franchise contract. We do not consider this advance consideration to include a significant financing component, since it is used to protect us from the property owner failing to adequately complete some or all of its obligations under the contract. • License fees are earned from: (i) a license agreement with HGV to use certain Hilton marks and IP in its timeshare business, which are typically billed and collected monthly, and revenue is generally recognized at the same time the fees are billed; and (ii) co-brand credit card arrangements, which are recognized as revenue when points for our guest loyalty program, Hilton Honors, are issued, generally as spend on the co-branded credit card occurs; see further discussion below under "Hilton Honors." Consideration paid or anticipated to be paid to incentivize hotel owners to enter into franchise contracts with us is amortized over the life of the applicable contract as a reduction to franchise fees. Management fees represent fees earned from hotels that we manage, usually under long-term contracts with the property owner, and include the following: • Base management fees are generally based on a percentage of the hotel's monthly gross revenue. Base fees are typically billed and collected monthly, and revenue is generally recognized as services are provided. • Incentive management fees are generally based on a percentage of the hotel's operating profits and in some cases may be subject to a stated return threshold to the property owner, normally over a one-calendar year period (the "incentive period"). Incentive fee revenue is recognized on a monthly basis, but only to the extent the cumulative fee earned does not exceed the probable fee for the incentive period. Incentive fee payment terms vary, but they are generally billed and collected monthly or annually upon completion of the incentive period. Consideration paid or anticipated to be paid to incentivize hotel owners to enter into management contracts with us is amortized over the life of the applicable contract as a reduction to base and other management fees. Other revenues from managed and franchised properties represent amounts that are contractually reimbursed to us by property owners, either directly as costs are incurred or indirectly through fees that are billed and collected in advance related to certain costs and expenses of the related properties, and include the following: • Direct reimbursements include payroll and related costs and certain other operating costs of the managed and franchised properties' operations, which are contractually reimbursed to us by the property owners as expenses are incurred. Revenue is recognized based on the amount of expenses incurred by Hilton, which are presented as other expenses from managed and franchised properties in our consolidated statements of operations, that are then reimbursed to us by the property owner typically on a monthly basis, which results in no net effect on operating income (loss) or net income (loss). • Indirect reimbursements include marketing expenses and other expenses associated with our brands and shared services, which are paid from fees collected by Hilton from the managed and franchised properties. Indirect reimbursements are typically billed and collected monthly, based on the underlying hotel's sales or usage (e.g., gross room revenues and number of reservations processed), and revenue is generally recognized as services are provided. System implementation fees charged to property owners are deferred and recognized as revenue over the term of the management or franchise contract. The corresponding expenses are expensed as incurred and are presented as other expenses from managed and franchised properties in our consolidated statements of operations and are expected to equal the revenues earned from indirect reimbursements over time. The management and franchise fees and reimbursements from third-party hotel owners are allocated to the performance obligations and the distinct services to which they relate using their estimated standalone selling prices. The terms of the fees earned under the contract relate to a specific outcome of providing the services (e.g., hotel room sales) or to Hilton's efforts (e.g., costs) to satisfy the performance obligations. We use time as the measure of progress to recognize as revenue the fees that are allocated to the period earned per the contract or to the period when the reimbursable costs are incurred. Owned and leased hotel revenues We identified the following performance obligations in connection with our owned and leased hotel revenues, for which revenue is recognized as the respective performance obligations are satisfied, which results in recognizing the amount we expect to be entitled to for providing the goods or services: • Cancellable room reservations or ancillary services are typically satisfied as the good or service is transferred to the hotel guest, which is generally when the room stay occurs. • Noncancellable room reservations and banquet or conference reservations represent a series of distinct goods or services provided over time and satisfied as each distinct good or service is provided, which is reflected by the duration of the room reservation. • Material rights for free or discounted goods or services are satisfied at the earlier point in time when the material right expires or the underlying free or discounted good or service is provided to the hotel guest. • Other ancillary goods and services are purchased independently of the room reservation at standalone selling prices and are considered separate performance obligations, which are satisfied when the related good or service is provided to the hotel guest. • Components of package reservations for which each component could be sold separately to other hotel guests are considered separate performance obligations and are satisfied as set forth above. Owned and leased hotel revenues primarily consist of hotel room rentals, revenue from accommodations sold in conjunction with other services (e.g., package reservations), food and beverage sales and other ancillary goods and services (e.g., parking) related to owned, leased and consolidated non-wholly owned hotel properties. Revenue is recognized when rooms are occupied or goods and services have been delivered or rendered, respectively. Payment terms typically align with when the goods and services are provided. Owned and leased hotel revenues are reduced upon issuance of Hilton Honors points for Hilton Honors members' paid stay transactions and are recognized when Hilton Honors points are redeemed for a free stay at an owned or leased hotel (see the "Hilton Honors" section below for additional information). Although the transaction prices of room rentals, goods and other services are generally fixed and based on the respective room reservation or other agreement, an estimate to reduce the transaction price is required if a discount is expected to be provided to the customer. For package reservations, the transaction price is allocated to the performance obligations within the package based on the estimated standalone selling prices of each component. On occasion, the hotel may also provide the customer with a material right to a free or discounted good or service in conjunction with a room reservation or banquet contract (e.g., free breakfast and free room night for every four nights booked). These material rights are considered separate performance obligations to which a portion of the transaction price is allocated based on the estimated standalone selling prices of the good or service, adjusted for the likelihood the hotel guest will exercise the right. Other revenues Other revenues include revenues generated by the incidental support of hotel operations for owned, leased, managed and franchised hotels, including purchasing operations, and other operating income. Purchasing revenues include any amounts received for vendor rebate arrangements that we participate in as a manager of hotels. Taxes and fees collected on behalf of governmental agencies We are required to collect certain taxes and fees from customers on behalf of governmental agencies and remit these back to the applicable governmental agencies on a periodic basis. We have a legal obligation to act as a collection agent. We do not retain these taxes and fees and, therefore, they are not included in our measurement of transaction prices. We have elected to present revenue net of sales taxes and other similar taxes. We record a liability when the amounts are collected and relieve the liability when payments are made to the applicable taxing authority or other appropriate governmental agency. Contract Assets Contract assets relate to incentive management fees for which the period of service has passed, but for which our right to consideration is conditional upon completing the requirements of the incentive fee period. Contract assets are included in other current assets in our consolidated balance sheets and are reclassified as accounts receivable when our right to consideration becomes unconditional. Contract Liabilities Contract liabilities relate to: (i) advance consideration received from hotel owners at contract inception for services considered to be part of the contract performance obligations, such as application, initiation and other fees; (ii) advance consideration received for certain indirect reimbursements, such as system implementation fees; and (iii) amounts received when points are issued under Hilton Honors, but for which revenue is not yet recognized, since the related points are not yet redeemed. Contract liabilities related to advance consideration received for fees and certain indirect reimbursements are recognized as revenue over the term of the related contract. Contract liabilities related to amounts received for Hilton Honors are recognized as revenue when the points are redeemed for a free good or service by the Hilton Honors member, which, on average, occurs within two years of points issuance. Contract liabilities are included in deferred revenues in our consolidated balance sheets.
Intangible Assets, Finite-Lived	Intangible Assets with Finite Useful Lives We have certain finite lived intangible assets that were initially recorded at their fair value in connection with the October 24, 2007 transaction whereby we became a wholly owned subsidiary of affiliates of The Blackstone Group L.P. ("Blackstone") (the "Merger"). These intangible assets consist of management contracts, franchise contracts, leases, certain proprietary technologies and our Hilton Honors guest loyalty program. Additionally, we capitalize cash consideration paid to incentivize hotel owners to enter into management and franchise contracts with us as contract acquisition costs and the incremental costs to obtain or fulfill the contracts as development commissions, which are generally fixed. We also capitalize costs incurred to develop internal-use computer software and costs to acquire software licenses, as well as internal and external costs incurred in connection with the development of upgrades or enhancements that result in additional information technology functionality. Intangible assets with finite useful lives are amortized using the straight-line method over their respective estimated useful lives, which for contract acquisition costs and development commissions is the contract term, including any renewal periods that are at our sole option. These estimated useful lives are generally as follows: management contracts recorded at the Merger ( 13 to 16 years); management contract acquisition costs and development commissions ( 20 to 30 years); franchise contracts recorded at the Merger ( 12 to 13 years); franchise contract acquisition costs and development commissions ( 10 to 20 years); leases ( 12 to 35 years); Hilton Honors ( 16 years); and capitalized software development costs ( 3 years). In our consolidated statements of operations, the amortization of these intangible assets, excluding contract acquisition costs, is included in depreciation and amortization expense, and the amortization of contract acquisition costs is recognized as a reduction to franchise fees and base and other management fees, based on contract type. Costs incurred prior to the acquisition of a contract, such as external legal costs, are expensed as incurred and included in general and administrative expenses in our consolidated statements of operations. Cash flows for contract acquisition costs and development commissions are included as operating activities in our consolidated statements of cash flows. We review all finite lived intangible assets for impairment when circumstances indicate that their carrying values may not be recoverable. If the carrying value of an asset group is not recoverable, we recognize an impairment loss for the excess carrying value over the fair value in our consolidated statements of operations.
Hilton Honors	Hilton Honors Hilton Honors is our guest loyalty and marketing program provided to our hotel and resort properties. Nearly all of our owned, leased, managed and franchised properties participate in the Hilton Honors program. Hilton Honors members earn points based on their spending at our participating properties and through participation in affiliated partner programs. When points are earned by Hilton Honors members, they are provided with a material right to free or discounted goods or services in the future upon accumulation of the required level of Hilton Honors points. Points may be redeemed for the right to stay at participating properties, as well as for other goods and services from third parties, including, but not limited to, airlines, car rentals, cruises, vacation packages, shopping and dining. As points are issued to a Hilton Honors member, the property or program partner pays Hilton Honors based on an estimated cost per point for the costs of operating the program, which include marketing, promotion, communication and administrative expenses, as well as the estimated cost of award redemptions. When these payments are received we record amounts equal to the estimated cost per point of the future redemption obligation within the liability for guest loyalty program and any amounts received in excess of the estimated cost per point within deferred revenues in our consolidated balance sheets. We engage outside actuaries to assist in determining the fair value of the future redemption obligation using statistical formulas that project future point redemptions based on factors that include historical experience, an estimate of points that will eventually be redeemed, which includes an estimate of "breakage" for points that will never be redeemed, and the cost of reimbursing properties and other third parties with respect to other redemption opportunities available to Hilton Honors members. When points are issued as a result of a stay at an owned or leased hotel, we recognize a reduction in owned and leased hotel revenues, since we are also the guest loyalty program sponsor. For the Hilton Honors fees that are charged to the participating properties, we allocate the fees to the material right created by the Hilton Honors points that are issued using the variable consideration allocation guidance, since the fees are directly related to the issuance of Hilton Honors points to the Hilton Honors member and Hilton's efforts to satisfy the future redemption of those Hilton Honors points. The transaction prices for the Hilton Honors points are reduced by the expected payments to the third parties that will provide the free or discounted room or service using the actuarial projection of the cost per point. The remaining transaction price is then further allocated to the points that are expected to be redeemed, adjusting the points that are issued for estimated breakage, and recognized when those points are redeemed. While the points are outstanding, both the estimate of the expected payments to third parties (cost per point) and the estimated breakage are reevaluated, and the amount of revenue recognized when each point is redeemed is adjusted so that the final amount allocated to the material right is reflective of the amount retained for providing the free or discounted goods and services, net of the payments to third parties and points not redeemed. We also earn license fees from co-brand credit card arrangements (see "Management and franchise revenues" within the "Revenue Recognition" section above). The co-brand license fee is allocated between two performance obligations based on their estimated standalone selling prices: (i) an IP license using the relief-from-royalty method; and (ii) material rights for free or discounted goods or services to the credit card customers using a cost plus method based on an evaluation of other third-party administrators. We satisfy our performance obligation related to points issued under Hilton Honors when points are redeemed for a free good or service by the Hilton Honors member, and we satisfy our remaining performance obligations over time as the customer simultaneously receives and consumes the benefits of the goods or services provided. Hilton Honors reimburses participating properties and applicable third parties when points are redeemed by members, at which time the redemption obligation is reduced and the related deferred revenue is recognized in other revenues from managed and franchised properties in our consolidated statements of operations. Additionally, when Hilton Honors members redeem award certificates at our owned and leased hotels, we recognize room revenue, included in owned and leased hotel revenues in our consolidated statements of operations.
New Accounting Pronouncements	Recently Issued Accounting Pronouncements Adopted Accounting Standards In March 2017, the Financial Accounting Standards Board ("FASB") issued ASU No. 2017-07 ("ASU 2017-07"), Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . This ASU requires employers to report the service cost component of net periodic pension cost in the same line item or items of the statement of operations as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net periodic pension cost must be presented separately from the service cost component and outside of a subtotal of income (loss) from operations. We adopted ASU 2017-07 on January 1, 2018 on a retrospective basis in our condensed consolidated statements of operations, which includes presenting: (i) the service cost component of net periodic pension cost in owned and leased hotel expenses and general and administrative expenses; and (ii) the other components of net periodic pension cost in other non-operating income (loss), net in our condensed consolidated statements of operations. Prior to adoption, all net periodic pension costs were presented in owned and leased hotel expenses and general and administrative expenses. We have applied the practical expedient permitting us to use the amounts disclosed in our "Employee Benefits Plans" note in our Annual Report on Form 10-K for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. See the "Prior Period Financial Information" below for the effect of the adoption of ASU 2017-07 on our condensed consolidated statements of operations for the three and nine months ended September 30, 2017 . In May 2014, the FASB issued ASU 2014-09. This ASU supersedes the revenue recognition requirements in Revenue Recognition (Topic 605) and requires entities to recognize revenue when a customer obtains control of promised goods or services and in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. Subsequent to ASU 2014-09, the FASB issued several related ASUs to clarify the application of the new revenue recognition standard, collectively referred to herein as ASU 2014-09. We adopted the requirements of ASU 2014-09 on January 1, 2018 using the full retrospective approach, as permitted by the standard, resulting in a cumulative adjustment to accumulated deficit of $212 million as of January 1, 2016. The provisions of ASU 2014-09 affected our revenue recognition as follows: • Application, initiation and other fees are recognized over the term of the franchise contract, rather than upon execution of the contract and the unamortized portion of these fees is included in deferred revenues in our consolidated balance sheets. • Contract acquisition costs related to our management and franchise contracts are recognized over the term of the contracts as a reduction to revenue, instead of as amortization expense. This change does not affect net income (loss). • Incentive management fees are recognized to the extent that it is probable that a significant reversal will not occur as a result of future hotel profits or cash flows, as opposed to recognizing amounts that would be due if the management contract was terminated at the end of the reporting period. This change does not affect net income (loss) for any full year period. • Revenue related to our Hilton Honors guest loyalty program is recognized upon point redemption, net of any reward reimbursement paid to a third party, as opposed to recognized on a gross basis at the time points are issued in conjunction with the accrual of the expected future cost of the reward reimbursement. Additionally, points issued at owned and leased hotels are accounted for as a reduction of owned and leased hotel revenues, as opposed to owned and leased hotel expenses. Fees received in excess of the estimated liability for guest loyalty program are included in deferred revenues in our consolidated balance sheets. • Reimbursable fees related to our management and franchise contracts are recognized as they are billed, as opposed to when we incur the related expenses. Timing differences related to the receipt and spend of these fees will no longer be recorded in other assets and other liabilities in our consolidated balance sheets. We have not retrospectively restated for contract modifications of management and franchise contracts that occurred before January 1, 2016. Instead, we have reflected the aggregate effect of all contract modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price. The estimated effect of applying this practical expedient is to use a longer period over which to straight line any fixed consideration either received from the customer or paid to the customer, since all fees will be amortized over the full contract term beginning on the date of initial execution, rather than amortizing fees received upon contract modifications prospectively from the contract modification date. We do not anticipate that this effect is material given the insignificance of the fixed consideration compared to the overall consideration we expect to earn over the term of the contract. See the "Prior Period Financial Information" below for the effect of the adoption of ASU 2014-09 on our condensed consolidated balance sheet as of December 31, 2017 and our condensed consolidated statements of operations for the three and nine months ended September 30, 2017 . Prior Period Financial Information The following table presents the effect of the adoption of ASU 2014-09 for the line items affected in our condensed consolidated balance sheet: December 31, 2017 As Previously Reported Adoption of ASU 2014-09 As Adjusted (in millions) ASSETS Accounts receivable, net $ 998 $ 7 $ 1,005 Prepaid expenses 111 16 127 Other current assets 171 (2 ) 169 Management and franchise contracts, net 909 44 953 Deferred income tax assets 113 (2 ) 111 Other non-current assets 434 (143 ) 291 TOTAL ASSETS 14,308 (80 ) 14,228 LIABILITIES AND EQUITY Current liabilities: Accounts payable, accrued expenses and other (1)(2) 1,487 (71 ) 1,416 Current portion of deferred revenues (1) 41 325 366 Deferred revenues 97 732 829 Deferred income tax liabilities 1,063 (132 ) 931 Other non-current liabilities 1,470 (550 ) 920 Total liabilities 12,233 304 12,537 Equity: Accumulated deficit (6,596 ) (385 ) (6,981 ) Accumulated other comprehensive loss (742 ) 1 (741 ) Total equity 2,075 (384 ) 1,691 TOTAL LIABILITIES AND EQUITY 14,308 (80 ) 14,228 ____________ (1) The current portion of deferred revenues has been separated from accounts payable, accrued expenses and other in the "As Previously Reported" column to conform with current presentation.

The balance was $622 million as of December 31, 2017 and did not change as a result of the adoption of ASU 2014-09. The following tables present the effect of the adoption of ASU 2014-09 and ASU 2017-07 on our condensed consolidated statements of operations: Three Months Ended September 30, 2017 As Previously Reported Adoption of ASU 2014-09 Adoption of ASU 2017-07 As Adjusted (in millions) Revenues Franchise fees $ 373 $ (15 ) $ — $ 358 Base and other management fees 87 (3 ) — 84 Incentive management fees 52 1 — 53 Owned and leased hotels 388 (5 ) — 383 Other revenues 21 — — 21 921 (22 ) — 899 Other revenues from managed and franchised properties 1,433 (241 ) — 1,192 Total revenues 2,354 (263 ) — 2,091 Expenses Owned and leased hotels 345 (5 ) — 340 Depreciation and amortization 83 — — 83 General and administrative 104 — 2 106 Other expenses 7 — — 7 539 (5 ) 2 536 Other expenses from managed and franchised properties 1,433 (210 ) — 1,223 Total expenses 1,972 (215 ) 2 1,759 Operating income 382 (48 ) (2 ) 332 Interest expense (100 ) 15 — (85 ) Gain on foreign currency transactions 2 — — 2 Other non-operating income, net 5 — 2 7 Income before income taxes 289 (33 ) — 256 Income tax expense (108 ) 12 — (96 ) Net income 181 (21 ) — 160 Net income attributable to noncontrolling interests (2 ) — — (2 ) Net income attributable to Hilton stockholders $ 179 $ (21 ) $ — $ 158 Earnings per share: Basic $ 0.56 $ 0.49 Diluted $ 0.55 $ 0.49 Nine Months Ended September 30, 2017 As Previously Reported Adoption of ASU 2014-09 Adoption of ASU 2017-07 As Adjusted (in millions) Revenues Franchise fees $ 1,039 $ (44 ) $ — $ 995 Base and other management fees 255 (9 ) — 246 Incentive management fees 160 (1 ) — 159 Owned and leased hotels 1,065 (13 ) — 1,052 Other revenues 78 — — 78 2,597 (67 ) — 2,530 Other revenues from managed and franchised properties 4,264 (731 ) — 3,533 Total revenues 6,861 (798 ) — 6,063 Expenses Owned and leased hotels 947 (13 ) 1 935 Depreciation and amortization 259 (7 ) — 252 General and administrative 326 — 4 330 Other expenses 41 — — 41 1,573 (20 ) 5 1,558 Other expenses from managed and franchised properties 4,264 (632 ) — 3,632 Total expenses 5,837 (652 ) 5 5,190 Operating income 1,024 (146 ) (5 ) 873 Interest expense (304 ) 44 — (260 ) Gain on foreign currency transactions 3 — — 3 Loss on debt extinguishment (60 ) — — (60 ) Other non-operating income, net 11 — 5 16 Income before income taxes 674 (102 ) — 572 Income tax expense (251 ) 38 — (213 ) Net income 423 (64 ) — 359 Net income attributable to noncontrolling interests (4 ) — — (4 ) Net income attributable to Hilton stockholders $ 419 $ (64 ) $ — $ 355 Earnings per share: Basic $ 1.29 $ 1.09 Diluted $ 1.28 $ 1.08 Accounting Standards Not Yet Adopted In August 2018, the 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 expensed 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. The provisions of ASU 2018-15 are effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years; early adoption is permitted. We are currently evaluating the effect that ASU 2018-15 will have on our consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02 ("ASU 2018-02"), Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . This ASU permits a reclassification from accumulated other comprehensive income (loss) to retained earnings (deficit) for stranded tax effects that do not reflect the appropriate tax rates as a result of the Tax Cuts and Jobs Act of 2017 (the "TCJ Act"). The provisions of ASU 2018-02 are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years and should be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the tax rate in the TCJ Act is recognized; early adoption is permitted. We plan to early adopt the provisions of ASU 2018-02 during the fourth quarter of 2018 and expect to reclassify approximately $10 million to $20 million from accumulated other comprehensive loss to accumulated deficit as of January 1, 2018. In February 2016, the FASB issued ASU No. 2016-02 ("ASU 2016-02"), Leases (Topic 842), 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 right-of-use 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-effect adjustment to the opening balance of retained earnings in the period of adoption. We intend to adopt ASU 2016-02 on January 1, 2019 and apply the package of practical expedients included therein, as well as utilize 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, our reporting for periods prior to January 1, 2019 will continue to be in accordance with Leases (Topic 840) . We are continuing to evaluate the effect that ASU 2016-02 will have on our consolidated financial statements, but we expect it to have a material effect on our consolidated balance sheet.
