Accounting Policies [Abstract]
Organization	Note 1: Organization Park Hotels & Resorts Inc. (“we,” “us,” “our” or the “Company”) is a Delaware corporation that owns a portfolio of premium-branded hotels and resorts primarily located in prime United States (“U.S.”) markets. On January 3, 2017, Hilton Worldwide Holdings Inc. (“Hilton” or “Parent”) completed the spin-off of a portfolio of hotels and resorts that established Park Hotels & Resorts Inc. as an independent, publicly traded company. The spin-off transaction was effected through a pro rata distribution of Park Hotels & Resorts Inc. stock to existing Hilton stockholders. As a result of the spin-off, each holder of Hilton common stock on the record date of December 15, 2016 received one share of our common stock for every five shares of Hilton common stock owned. For U.S. federal income tax purposes, we are taxed as a real estate investment trust (“REIT”). We are currently, and expect to continue to be, organized and operate in a REIT qualified manner. From the spin-off date, Park Intermediate Holdings LLC (our “Operating Company”), directly or indirectly, holds all of our assets and conducts all of our operations. We own 100% of the interests in our Operating Company.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Note 2: Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation Principles of Combination and Consolidation Subsequent to January 3, 2017, the consolidated financial statements include the accounts of the Company, our wholly owned subsidiaries and entities in which we have a controlling financial interest, including variable interest entities (“VIEs”) where we are the primary beneficiary. The pre-spin consolidated financial statements through January 3, 2017 represent the financial position and results of operations of entities held by us after the spin-off that had historically been under common control of the Parent. The pre-spin consolidated financial statements were prepared on a carve-out basis and reflect significant assumptions and allocations. The consolidated financial statements reflect our financial position, results of operations and cash flows, in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). All significant intercompany transactions and balances within these consolidated financial statements have been eliminated. On October 24, 2007, a predecessor to Hilton became a wholly owned subsidiary of an affiliate of The Blackstone Group L.P. (“Blackstone”) following the completion of a merger (“Merger”). Our consolidated financial statements reflect adjustments made as a result of applying push down accounting at the time of the Merger. The Company’s consolidated financial statements include certain assets and liabilities that have historically been held by Hilton but are specifically identifiable or otherwise attributable to the Company, including goodwill and intangibles. Allocations Through January 3, 2017, the pre-spin consolidated statements of comprehensive income included allocations of corporate general and administrative expenses from Hilton on the basis of financial and operating metrics that Hilton historically used to allocate resources and evaluate performance against its strategic objectives. We considered the basis on which expenses were allocated to be a reasonable reflection of the utilization of services provided to or the benefit received by us during the historical periods presented. However, the allocations may not include all of the actual expenses that would have been incurred by us and may not reflect our consolidated results of operations, financial position and cash flows had we been a stand-alone company during the historical periods presented. Actual costs that might have been incurred had we been a stand-alone company would depend on a number of factors, including the chosen organizational structure, what functions we might have performed ourselves or outsourced and strategic decisions we might have made in areas such as information technology and infrastructure. Following the spin-off, we performed these functions using our own resources or purchased services. For an interim period, some of these functions were provided by Hilton through a transition services agreement (“TSA”). The majority of the services provided pursuant to the TSA were terminated effective January 1, 2018 and the TSA expired on December 31, 2018. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Reclassifications Certain line items on the consolidated balance sheet as of December 31, 2017 and on the statements of comprehensive income and statements of cash flows for the years ended December 31, 2017 and 2016 have been reclassified to conform to the current period presentation. Summary of Significant Accounting Policies Property and Equipment Property and equipment are recorded at cost, and interest applicable to major construction or development projects is capitalized. Costs of improvements that extend the economic life or improve service potential are also capitalized. Capitalized costs are depreciated over their estimated useful lives. Costs for normal repairs and maintenance are expensed as incurred. Depreciation is recorded using the straight-line method over the assets’ estimated useful lives, which are generally as follows: buildings and improvements (8 to 40 years); furniture and equipment (3 to 8 years); and computer equipment and acquired software (3 years). Leasehold improvements are depreciated over the shorter of the estimated useful life, based on the estimates above, or the lease term. We evaluate the carrying value of our property and equipment if there are indicators of potential impairment. We perform an analysis to determine the recoverability of the asset’s carrying value by comparing the expected undiscounted future cash flows to the net book value of the asset. If it is determined that the expected undiscounted future cash flows are less than the net book value of the asset, the excess of the net book value over the estimated fair value is recorded in our consolidated statements of comprehensive income within impairment losses. Fair value is generally estimated using valuation techniques that consider the discounted cash flows of the asset using discount and capitalization rates deemed reasonable for the type of asset, as well as prevailing market conditions, appraisals, recent similar transactions in the market and, if appropriate and available, current estimated net sales proceeds from pending offers. If sufficient information exists to reasonably estimate the fair value of a conditional asset retirement obligation, including environmental remediation liabilities, we recognize the fair value of the obligation when the obligation is incurred, which is generally upon acquisition, construction or development and/or through the normal operation of the asset. Assets Held for Sale We classify a property as held for sale when we commit to a plan to sell the asset, the sale of the asset is probable within one year, and it is unlikely that action to complete the sale will change or that the sale will be withdrawn. When we determine that classification of an asset as held for sale is appropriate, we cease recording depreciation for the asset and value the property at the lower of depreciated cost or fair value, less costs to dispose. Further, the related assets and liabilities of the held for sale property will be classified as assets held for sale in our consolidated balance sheets. Any gains on sales of properties are recognized at the time of sale or deferred and recognized in net income (loss) Investments in Affiliates The consolidated financial statements include entities in which we have a controlling financial interest, including VIEs where we are the primary beneficiary. The determination of a controlling financial interest is based upon the terms of the governing agreements of the respective entities, including the evaluation of rights held by other interests. If the entity is considered to be a VIE, we determine whether we are the primary beneficiary, and then consolidate those VIEs for which we have determined we are the primary beneficiary. If the entity in which we hold an interest does not meet the definition of a VIE, we evaluate whether we have a controlling financial interest through our voting interests in the entity. We consolidate entities when we own more than 50 percent of the voting shares of a company or otherwise have a controlling financial interest. References in these financial statements to net income (loss) attributable to stockholders We hold investments in affiliates that primarily own or lease hotels. Investments in affiliates over which we exercise significant influence, but lack a controlling financial interest, are accounted for using the equity method. We account for investments using the equity method when we have the ability to exercise significant influence over the entity, typically through a more than minimal investment. Our proportionate share of earnings (losses) from our equity method investments is presented as equity in earnings (losses) from investments in affiliates We assess the recoverability of our equity method investments if there are indicators of potential impairment. If an identified event or change in circumstances requires an evaluation to determine if an investment may have an other-than-temporary impairment, we assess the fair value of the investment based on accepted valuation methodologies, which include discounted cash flows, estimates of sales proceeds and external appraisals. If an investment’s fair value is below its carrying value and the decline is considered to be other-than-temporary, we will recognize an impairment loss in equity in earnings (losses) from investments in affiliates Non-controlling Interests We present the portion of any equity that we do not own in entities that we have a controlling financial interest (and thus consolidate) as non-controlling interests and classify those interests as a component of total equity, separate from total stockholders’ equity, on our consolidated balance sheets. For consolidated joint ventures with pro rata distribution allocations, net income or loss is allocated between the joint venture partners based on their respective stated ownership percentages. In addition, we include net income (loss) attributable to the noncontrolling interest in net income (loss) Goodwill Goodwill represents the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. We do not amortize goodwill, but rather evaluate goodwill for potential impairment on an annual basis or at other times during the year if events or circumstances indicate that the carrying amount may not be recoverable. We have two reporting units, consolidated and unconsolidated hotels, to which goodwill has been allocated. Certain of the entities that are included in our consolidated financial statements were consolidated subsidiaries of our Parent at the time of the Merger. Our Parent allocated goodwill to us based on the relative fair value of our properties compared to that of Parent’s ownership segment as of the date of the Merger. We review the carrying value of goodwill by comparing the carrying value of a reporting unit to its fair value. In any year, we may elect to perform a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is in excess of its carrying value. If we cannot determine qualitatively that the fair value is in excess of the carrying value, or we decide to bypass the qualitative assessment, we proceed to the two-step quantitative process. In the first step, we determine the fair value of the reporting unit. The valuation is based on internal projections of expected future cash flows and operating plans, as well as market conditions relative to the operations of our reporting unit. If the estimated fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired and the second step of the impairment test is not necessary. However, if the carrying amount of the reporting unit exceeds its estimated fair value, then the second step must be performed. In the second step, we estimate the implied fair value of goodwill, which is determined by taking the fair value of the reporting unit and allocating it to all of its assets and liabilities (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, the excess is recognized within casualty (gain) loss and impairment loss, net Intangible Assets Intangible assets with finite useful lives primarily include ground and hotel operating lease contracts recorded by our Parent at the time of the Merger and allocated to us based on either specific identification or the relative fair values as of the date of the Merger. These contract values are based on the present value of the difference between contractual amounts to be paid pursuant to the contracts acquired and the estimate of the fair value of rates for corresponding contracts measured over the period equal to the remaining non-cancelable term of the contract. Intangible assets are amortized using the straight-line method over the remaining non-cancelable term of the contract. We review all finite lived intangible assets for impairment when circumstances indicate that their carrying amounts may not be recoverable. If the carrying value of an asset group is not recoverable, we recognize an impairment loss for the excess of the carrying value over the fair value in our consolidated statements of comprehensive income. Asset Acquisitions We consider an asset acquisition to occur when substantially all the fair value of an acquisition is concentrated in a single identifiable asset or a group of similar identifiable assets. In an acquisition of assets, we are not required to expense our acquisition-related costs, and goodwill is not assigned. We will account for the properties purchased as asset acquisitions by allocating the total cash consideration, including transaction costs, to the individual assets acquired and liabilities assumed, respectively, on a relative fair value basis. Business Combinations We consider a business combination to occur when we take control of a business by acquiring its net assets or equity interests. We record the assets acquired, liabilities assumed and non-controlling interests at fair value as of the acquisition date, including any contingent consideration. We evaluate factors, including market data for similar assets, expected future cash flows discounted at risk-adjusted rates and replacement cost for the assets to determine an appropriate fair value of the assets. Acquisition-related costs, such as due diligence, legal and accounting fees, are expensed in the period incurred and are not capitalized or applied in determining the fair value of the acquired assets. Cash and Cash Equivalents Cash and cash equivalents include all highly liquid investments with original maturities, when purchased, of three months or less. Restricted Cash Restricted cash includes cash balances established as lender reserves required by our debt agreements. For purposes of our consolidated statement of cash flows, changes in restricted cash caused by changes in lender reserves due to restrictions under our loan agreements are shown as financing activities and changes in deposits for assets we plan to acquire are shown as investing activities. Allowance for Doubtful Accounts An allowance for doubtful accounts is provided on accounts receivable when losses are probable based on historical collection activity and current business conditions. Fair Value Measurements—Valuation Hierarchy Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date (an exit price). We use the three-level valuation hierarchy for classification of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Inputs refer broadly to the assumptions that market participants would use in pricing an asset or liability. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-level hierarchy of inputs is summarized below: • Level 1—Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2—Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the instrument. • Level 3—Valuation is based upon other unobservable inputs that are significant to the fair value measurement. The classification of assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement in its entirety at the end of each reporting period. Derivative Instruments We may use derivative instruments as part of our overall strategy to manage our exposure to market risks associated with fluctuations in interest rates. We will regularly monitor the financial stability and credit standing of the counterparties to our derivative instruments. Under the terms of certain loan agreements, we may be required to maintain derivative financial instruments to manage interest rates. We do not enter into derivative financial instruments for trading or speculative purposes. We record all derivatives at fair value. On the date the derivative contract is entered, we designate the derivative as one of the following: a hedge of a forecasted transaction or the variability of cash flows to be paid (“cash flow hedge”); a hedge of the fair value of a recognized asset or liability (“fair value hedge”); or an undesignated hedge instrument. Changes in the fair value of a derivative that is qualified, designated and highly effective as a cash flow hedge or net investment hedge are recorded in Other comprehensive income (loss) in the consolidated statements of comprehensive income until they are reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Changes in the fair value of a derivative that is qualified, designated and highly effective as a fair value hedge, along with the gain or loss on the hedged asset or liability that is attributable to the hedged risk, are recorded in current period earnings. Changes in the fair value of undesignated derivative instruments and the ineffective portion of designated derivative instruments are reported in current period earnings. Cash flows from designated derivative financial instruments are classified within the same category as the item being hedged in the consolidated statements of cash flows. Cash flows from undesignated derivative financial instruments are included as an investing activity in our consolidated statements of cash flows. If we determine that we qualify for and will designate a derivative as a hedging instrument, at the designation date we formally document all relationships between hedging activities, including the risk management objective and strategy for undertaking various hedge transactions. This process includes matching all derivatives that are designated as cash flow hedges to specific forecasted transactions and linking all derivatives designated as fair value hedges to specific assets and liabilities in our consolidated balance sheets. To the extent we have designated a derivative as a hedging instrument, each reporting period we assess the effectiveness of our designated hedges in offsetting the variability in the cash flows or fair values of the hedged assets or obligations using the Hypothetical Derivative Method. This method compares the cumulative change in fair value of each hedging instrument to the cumulative change in fair value of a hypothetical hedging instrument, which has terms that identically match the critical terms of the respective hedged transactions. Thus, the hypothetical hedging instrument is presumed to perfectly offset the hedged cash flows. Ineffectiveness results when the cumulative change in the fair value of the hedging instrument exceeds the cumulative change in the fair value of the hypothetical hedging instrument. We discontinue hedge accounting prospectively, when the derivative is not highly effective as a hedge, the underlying hedged transaction is no longer probable, or the hedging instrument expires, is sold, terminated or exercised. Revenue Recognition Our results of operations primarily consist of room rentals, food and beverage sales and other ancillary goods and services from hotel properties. Other revenues are from our laundry business and service arrangements with Hilton Grand Vacations (“HGV”). Hotel operating revenues are disaggregated into room revenue, food and beverage revenue, ancillary hotel revenue and other revenue on the consolidated statements of comprehensive income to illustrate how economic factors affect the nature, amount and timing, and uncertainty of revenue and cash flows. Rooms revenue is recognized over time when rooms are occupied and food and beverage revenue is recognized at a point in time when goods and services have been delivered or rendered. Ancillary hotel revenue and other revenue is generally recognized at a point in time as goods and services are delivered or rendered. We assess if we are the principal or agent for certain ancillary services provided by third parties. If we are the principal, we recognize revenue based on the gross sales price. If we are the agent, we recognize revenue net of costs paid to service providers. Payment received for a future stay or event is recognized as an advance deposit, which is included in other liabilities Currency Translation The United States dollar (“USD”) is our reporting currency and is the functional currency of our consolidated and unconsolidated entities operating in the U.S. The functional currency for our consolidated and unconsolidated entities operating outside of the U.S. is the currency of the primary economic environment in which the respective entity operates. Assets and liabilities measured in foreign currencies are translated into USD at the prevailing exchange rates in effect as of the financial statement date and the related gains and losses, net of applicable deferred income taxes, are reflected in accumulated other comprehensive income (loss) (loss) gain on foreign currency transactions Share-based Compensation We recognize the cost of services received in share-based payment transactions with employees and non-employee directors as services are received and recognize a corresponding increase in additional paid-in capital for equity classified awards. We account for any forfeitures when they occur. The measurement objective for these equity awards is the estimated fair value at the grant date of the equity instruments that we will be obligated to issue when employees have rendered the requisite service and satisfied any other conditions necessary to earn the right to benefit from the instruments. The compensation expense for an award classified as an equity instrument is recognized ratably over the requisite service period. The requisite service period is the period during which an employee is required to provide service in exchange for an award. Income Taxes We are a REIT for U.S. federal income tax purposes, and we expect to continue to be organized and operate so as to qualify as a REIT. To qualify as a REIT, we must continually satisfy tests concerning, among other things, the real estate qualification of sources of our income, the real estate composition and values of our assets, the amounts we distribute to our stockholders annually and the diversity of ownership of our stock. To the extent we continue to qualify as a REIT, we generally will not be subject to U.S. federal income tax on taxable income generated by our REIT activities that we distribute to our stockholders. Accordingly, no provision for U.S. federal income taxes has been included in our accompanying consolidated financial statements for the years ended December 31, 2018 and 2017 related to our REIT activities, other than the derecognition and remeasurement of deferred tax assets and liabilities associated with our election to be taxed as a REIT and taxes associated with built-in gains related to our assets owned at the date of our spin-off. In addition, we are subject to non-U.S. income tax on foreign held REIT activities. Further, our taxable REIT subsidiaries (“TRSs”) are generally subject to U.S. federal, state and local, and foreign income taxes (as applicable). Through January 3, 2017, we had been included in the consolidated U.S. federal income tax return of Hilton, as well as certain state tax returns where Hilton files on a consolidated or combined basis, and foreign tax returns, as applicable. For purposes of our pre-spin consolidated financial statements, we have recorded deferred tax balances as if we filed tax returns on a stand-alone basis separate from Hilton, but not as a REIT. The separate return method applies the accounting guidance for income taxes to the stand-alone financial statements as if we were a separate taxpayer and a standalone enterprise for the periods presented. The calculation of our income taxes on a separate return basis requires a considerable amount of judgment and use of both estimates and allocations. We believe that the assumptions and estimates used to determine these tax amounts are reasonable. However, our consolidated financial statements may not necessarily reflect what our tax amounts would have been if we had been a stand-alone enterprise during the periods presented. We account for income taxes using the asset and liability method. The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current year, to recognize the deferred tax assets and liabilities that relate to tax consequences in future years, which result from differences between the respective tax basis of assets and liabilities and their financial reporting amounts, and tax loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which the respective temporary differences or operating loss or tax credit carry forwards are expected to be recovered or settled. The realization of deferred tax assets and tax loss and tax credit carry forwards is contingent upon the generation of future taxable income and other restrictions that may exist under the tax laws of the jurisdiction in which a deferred tax asset exists. Valuation allowances are provided to reduce such deferred tax assets to amounts more likely than not to be ultimately realized. We use a prescribed recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return. For all income tax positions, we first determine whether it is “more-likely-than-not” that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. If it is determined that a position meets the more-likely-than-not recognition threshold, the benefit recognized in the financial statements is measured as the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement.

Depreciation of property and equipment, including capital lease assets, was $273 million, $283 million and $295 million during the years ended December 31, 2018, 2017 and 2016, respectively. As of December 31, 2018 and 2017, property and equipment included approximately $1 million and $20 million, respectively, of capital lease assets primarily consisting of buildings and leasehold improvements, net of $0 million and $10 million, respectively, of accumulated depreciation. Certain capital lease assets were disposed of in connection with the sale of our UK portfolio in February 2018. Additionally, the City of Chicago did not extend the ground lease for the Hilton Chicago O’Hare Airport, which ended on December 31, 2018. Accordingly, the city of Chicago assumed ownership of the hotel as of the end of the contract term. Transactions with HGV In October 2016, we completed the sale of 600 rooms at the Hilton Waikoloa Village to HGV in connection with timeshare projects. The net book value of these assets was approximately $177 million. Due to our continuing involvement, this transaction was not recognized as a sale and was accounted for as a sales-leaseback liability under the financing method. The assets will be derecognized at the end of lease term. Pursuant to an arrangement representing a lease, we reserved exclusive rights to occupy and operate these rooms beginning on the date of transfer and continuing until the end of the lease term. The lease term expires December 2019, but may be extended if mutually agreed to by all parties. During 2017, 134 of the 600 rooms at the Hilton Waikoloa Village previously transferred to HGV and leased back by us were released to HGV; accordingly, we derecognized $38 million of property and equipment, net, and the related $39 million liability due to HGV. During 2018, we transferred a restaurant at the Hilton Waikoloa Village to HGV and derecognized $3 million of property and equipment, net and $3 million of the related liability due to HGV. In June 2016, we transferred assets, including legal title, related to certain floors at the Embassy Suites Washington, D.C. to HGV in connection with a timeshare project. The net book value of these assets was approximately $40 million. No cash consideration was received for this transfer; therefore, the net book value of the assets was recognized as a $33 million non-cash equity distribution to Parent for the year ended December 31, 2016. Hurricanes Irma and Maria In September 2017, Hurricanes Irma and Maria caused damage and disruption at certain of our hotels in Florida and the Caribe Hilton in Puerto Rico. Our insurance coverage provides us with reimbursement for the replacement cost for the damage to these hotels, which includes certain clean-up and repair costs, exceeding the applicable deductibles, in addition to loss of business. During the year ended December 31, 2017 , we incurred $20 million of expenses and recognized a loss of $54 million for property and equipment that was damaged during the hurricanes, both of which are included in casualty (gain) loss and impairment loss, net in our consolidated statement of comprehensive income. We received $2 million of insurance proceeds, none of which related to business interruption insurance. The insurance receivable as of December 31, 2017 was $56 million, which is included within other assets in our consolidated balance sheets. During the year ended December 31, 2018 , we incurred an additional 35 million of expenses, and based upon additional information, we recognized an additional loss of $22 million for property and equipment that was damaged during the hurricanes. These amounts were offset by the recognition of an additional insurance receivable of $ 57 million. We received $ 119 million of insurance proceeds, of which $ 25 million related to business interruption and $6 million related to expense reimbursements. Business interruption proceeds are included within ancillary hotel revenue in our consolidated statements of comprehensive income.

Consolidated Variable Interest Entities ("VIEs") and Investments in Affiliates	Note 5: Consolidated Variable Interest Entities ("VIEs") and Investments in Affiliates Consolidated VIEs We consolidate three VIEs that own hotels in the U.S. We are the primary beneficiary of these 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 VIEs are only available to settle the obligations of these entities.

(2) $1 billion available. (3) Capital lease obligations of $15 million were disposed of in connection with the sale of our UK portfolio in February 2018. CMBS Loans and Mortgage Loans In October 2016, we entered into a $725 million CMBS loan secured by the Hilton San Francisco Union Square and the Parc 55 Hotel San Francisco (“SF CMBS Loan”) and a $1.275 billion CMBS loan secured by the Hilton Hawaiian Village Waikiki Beach Resort (“HHV CMBS Loan”). Both the SF CMBS Loan and the HHV CMBS Loan bear interest at a fixed-rate and require interest-only payments through their respective maturity dates. At any time after the permitted release date of May 1, 2019, or earlier subject to certain conditions, the SF CMBS Loan and HHV CMBS Loan may be partially or fully prepaid, subject to prepayment penalties. Our mortgage loans, which are associated with our three consolidated VIEs, bear interest at either a fixed-rate or variable rate. We are required to deposit with lenders certain cash reserves for restricted uses. As of December 31, 2018 and 2017, our consolidated balance sheets included $15 million and $14 million, respectively, of restricted cash related to our CMBS loans and mortgage loans. Credit Facilities In December 2016, we entered into a credit agreement (“Credit Agreement”) with Wells Fargo Bank, National Association as administrative agent, and certain others financial institutions party thereto as lenders. The facility includes a $1 billion revolving credit facility (“Revolver”), which has a scheduled maturity date of December 24, 2020 with two, six-month extension options if certain conditions are satisfied, and a $750 million term loan (“Term Loan”). The Credit Agreement includes the option to increase the size of the Revolver and enter into additional incremental term loan credit facilities, subject to certain limitations, in an aggregate commitment or principal amount not to exceed $500 million for all such increases. The Revolver permits one or more standby letters of credit, up to a maximum aggregate outstanding balance of $50 million, to be issued on behalf of us. Any outstanding standby letters of credit reduce the available borrowings on the Revolver by a corresponding amount. Revolver and Term Loan borrowings bear interest at variable rates at our option, based upon either a base rate or LIBOR rate, plus an applicable margin based on our leverage ratio. We incur an unused facility fee on the Revolver of between 0.2% and 0.3%, based on our level of usage. The Credit Agreement contains certain financial covenants relating to our maximum leverage ratio, minimum fixed charge coverage ratio, maximum secured indebtedness, maximum unsecured indebtedness and minimum unsecured interest coverage ratio. If an event of default exists, we are not permitted to make distributions to shareholders, other than those required to qualify for and maintain REIT status. Debt Maturities The contractual maturities of our debt, assuming the exercise of all extensions that are exercisable solely at our option, as of December 31, 2018 were: Year (in millions) 2019 $ — 2020 12 2021 751 2022 32 2023 729 Thereafter (1) 1,434 $ 2,958 (1) Assumes the exercise of all extensions that are exercisable solely at our option.

We are subject to ground leases for 14 of our consolidated properties and 3 of our unconsolidated joint ventures. Our leases expire at various dates through 2071, with varying renewal options, and the majority expire before 2026. Our operating leases may require minimum rent payments, contingent rent payments based on a percentage of revenue or income or rent payments equal to the greater of a minimum rent or contingent rent. In addition, we may be required to pay some, or all, of the capital costs for property and equipment in the hotel during the term of the lease.

Income Taxes	Note 10: Income Taxes We are a REIT for U.S. federal income tax purposes, and we expect to continue to be organized and operate so as to continue to qualify as a REIT. To qualify as a REIT, we must satisfy requirements related to, among other things, the real estate qualification of sources of our income, the real estate composition and values of our assets, the amounts we distribute to our stockholders annually and the diversity of ownership of our stock. To the extent we continue to qualify as a REIT, we generally will not be subject to U.S. federal income tax on taxable income generated by our REIT activities that we distribute annually to our stockholders. Accordingly, no provision for U.S. federal income taxes has been included in our accompanying consolidated financial statements for the years ended December 31, 2018 and 2017 related to our REIT activities, other than taxes associated with built-in gains related to our assets owned at the date of our spin-off and the remeasurement of deferred tax assets and liabilities. H.R. 1, commonly referred to as The Tax Cuts and Jobs Act of 2017 (the “Act”) was enacted on December 22, 2017. The Act, which amended the Internal Revenue Code of 1986, was the most significant tax legislative development in decades. Major elements of the Act from our perspective include reducing the corporate tax rate; restricting the eligibility for tax deferred like-kind exchange treatment solely to real property; limiting the deductibility of interest expense; the one-time transition tax on foreign cash and unremitted earnings; and the treatment of global intangible low-taxed income for REIT gross income purposes. We completed our analysis, and as a result of the changes in the Act, we recognized a $25 million income tax benefit for the year ended December 31, 2017 and an additional $8 million of income tax expense for the year ended December 31, 2018 when our analysis of the effects of the Act was completed. We will be subject to U.S. federal income tax on taxable sales of built-in gain property (representing property with an excess of fair value over tax basis held by us on January 4, 2017) during the five-year period following the date of our spin-off. In addition, we are subject to non-U.S. income tax on foreign held REIT activities. Further, our taxable REIT subsidiaries (“TRSs”) are generally subject to U.S. federal, state and local, and foreign income taxes (as applicable). Our tax provision includes U.S. federal, state and foreign income taxes payable. The domestic and foreign components of income before income taxes were: Year Ended December 31, 2018 2017 2016 (in millions) U.S. income before tax $ 498 $ 279 $ 188 Foreign income before tax 2 6 33 Income before income taxes $ 500 $ 285 $ 221 The components of our (benefit) provision for income taxes were: Year Ended December 31, 2018 2017 2016 (in millions) Current: U.S. Federal $ 34 $ 21 $ 130 State 6 2 16 Foreign 3 9 2 Total current 43 32 148 Deferred: U.S. Federal (18 ) (2,373 ) (60 ) State — — (7 ) Foreign (2 ) (5 ) 1 Total deferred (20 ) (2,378 ) (66 ) Total provision (benefit) for income taxes $ 23 $ (2,346 ) $ 82 Reconciliations of our tax provision at the U.S. statutory rate to the (benefit) provision for income taxes were: Year Ended December 31, 2018 2017 2016 (in millions) Statutory U.S. federal income tax provision $ 105 $ 100 $ 77 State income taxes, net of U.S. federal tax benefit 3 2 9 Foreign income tax expense 2 4 5 U.S. benefit of foreign taxes — — (3 ) Change in deferred tax asset valuation allowance — 3 (2 ) Change in basis difference in foreign subsidiaries — — (5 ) Tax rate change (2 ) (25 ) — Non-deductible transaction costs — — 3 REIT income not subject to tax (92 ) (83 ) — Derecognition and remeasurement of deferred taxes 7 (2,347 ) — Other, net — — (2 ) Provision (benefit) for income taxes $ 23 $ (2,346 ) $ 82 Through January 3, 2017, we had been included in the consolidated U.S. federal income tax return of Hilton, as well as certain state tax returns where Hilton filed on a consolidated or combined basis, and foreign tax returns, as applicable. During the year ended December 31, 2016, Hilton paid $146 million of income tax liabilities related to us. Deferred income taxes represent the tax effect of the differences between the book and tax bases of assets and liabilities plus carryforward items. The composition of net deferred tax balances were as follows: December 31, 2018 2017 (in millions) Deferred income tax assets ( 1) $ 3 $ 6 Deferred income tax liabilities (42 ) (65 ) Net deferred tax liability $ (39 ) $ (59 ) (1) Included within other assets The tax effects of the temporary differences and carryforwards that give rise to our net deferred tax liability were: December 31, 2018 2017 (in millions) Deferred tax assets: Net operating loss carryforwards $ 8 $ 10 Other reserves — 1 Capital lease obligations — 2 Deferred income 3 3 Property and equipment 1 7 Accrued compensation 3 2 Other 3 2 Total gross deferred tax assets 18 27 Less: valuation allowance (4 ) (4 ) Deferred tax assets $ 14 $ 23 Deferred tax liabilities: Property and equipment $ (44 ) $ (77 ) Investments (9 ) (4 ) Other — (1 ) Deferred tax liabilities (53 ) (82 ) Net deferred tax liability $ (39 ) $ (59 ) As of December 31, 2018, we had U.S. federal, state and foreign net operating loss carryforwards of $58 million, which resulted in deferred tax assets of $8 million. Our U.S. federal and state net operating loss carryforwards of approximately $10 million and $19 million begin to expire in 2038 and 2025, respectively and our foreign net operating loss carryforwards of approximately $29 million are not subject to expiration. There was no change to our valuation allowance during the year ended December 31, 2018. For periods ended prior to January 4, 2017, Hilton filed income tax returns, including returns for us, with U.S. federal, state and foreign jurisdictions. Hilton is under regular and recurring audit by the Internal Revenue Service 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 state, local, U.S. federal and foreign tax jurisdictions or from the resolution of various proceedings between the U.S. and foreign tax authorities. Hilton is no longer subject to U.S. federal income tax examination for years through 2005. As of December 31, 2018, Hilton remains subject to U.S. federal examinations from 2006 through 2016, state examinations from 2006 through 2016 and foreign examinations of their income tax returns for the years 1997 through 2016. We will be subject to U.S. federal, state and foreign examinations for periods ending after January 4, 2017. For U.S. federal income tax purposes, the cash distributions to stockholders are characterized as follows: For the Year Ended For the Year Ended December 31, 2018 December 31, 2017 Common distributions (per share): Ordinary dividends $ 1.64 $ 4.41 Qualified dividends — 2.62 Capital gain distributions 1.32 —

Share-Based Compensation	Note 11: Share-Based Compensation We issue equity-based awards to our employees pursuant to the 2017 Omnibus Incentive Plan (“2017 Employee Plan”) and our non-employee directors pursuant to the 2017 Stock Plan for Non-Employee Directors (“2017 Director Plan”). The 2017 Employee Plan provides that a maximum of 8,000,000 shares of our common stock may be issued, and as of December 31, 2018, 6,059,579 shares of common stock remain available for future issuance. The 2017 Director Plan provides that a maximum of 450,000 shares of our common stock may be issued, and as of December 31, 2018, 345,768 shares of common stock remain available for future issuance. For the years ended December 31, 2018 and 2017, we recognized $16 and $15 million of share-based compensation expense. As of December 31, 2018, unrecognized compensation expense was $17 million, which is expected to be recognized over a weighted-average period of 1.2 years. The total fair value of shares vested during each of the years ended December 31, 2018 and 2017 was $9 million. Restricted Stock Awards Restricted Stock Awards (“RSAs”) generally vest in annual installments between one and three years from each grant date. The following table provides a summary of RSAs for the years ended December 31, 2018 and 2017: Number of Shares Weighted-Average Grant Date Fair Value Unvested at January 1, 2017 — $ — Granted 594,213 26.52 Vested (106,795 ) 26.85 Forfeited (25,779 ) 26.22 Unvested at December 31, 2017 461,639 26.47 Granted 367,463 27.34 Vested (214,208 ) 26.67 Forfeited (29,788 ) 27.48 Unvested at December 31, 2018 585,106 $ 26.89 Performance Stock Units Performance Stock Units (“PSUs”) generally vest at the end of a two or three-year performance period and are subject to the achievement of a market condition based on a measure of our total shareholder return relative to the total shareholder return of the companies that comprise the FTSE NAREIT Lodging Resorts Index (that have a market capitalization in excess of $1 billion as of the first day of the applicable performance period). The number of PSUs that may become vested ranges from zero to 200% of the number of PSUs granted to an employee, based on the level of achievement of the foregoing performance measure. The following table provides a summary of PSUs for the years ended December 31, 2018 and 2017: Number of Shares Weighted-Average Grant Date Fair Value Unvested at January 1, 2017 — $ — Granted 387,642 31.95 Vested — — Forfeited (16,085 ) 31.73 Unvested at December 31, 2017 371,557 31.96 Granted 179,774 29.47 Vested — — Forfeited (13,395 ) 30.48 Unvested at December 31, 2018 537,936 $ 31.16 The grant date fair values of these awards were determined using a Monte Carlo simulation valuation model with the following assumptions: Year Ended December 31, 2018 2017 Expected volatility (1) 20.0% - 24.0% 25.5% - 29.5% Dividend yield (2) — — Risk-free rate 2.4% - 2.7% 1.2% - 1.5% Expected term 3 years 2 - 3 years (1) Due to limited trading history of our common stock, we used the historical and implied volatilities of our peer group in addition to our historical and implied volatilities over the performance period to estimate appropriate expected volatilities.

Hotel Management Operating And License Agreements [Abstract]
Hotel Management Operating and License Agreements	Note 13: Hotel Management Operating and License Agreements Management and Franchise Fees We have management agreements, whereby we pay a base fee equal to a percentage of total revenues, as defined, as well as an incentive fee if specified financial performance targets are achieved. Our managers generally have sole responsibility for all activities necessary for the operation of the hotels, including establishing room rates, processing reservations and promoting and publicizing the hotels. Our managers also generally provide all employees for the hotels, prepare reports, budgets and projections, and provide other administrative and accounting support services to the hotels. We have consultative and limited approval rights with respect to certain actions of our managers, including entering into long-term or high value contracts, engaging in certain actions relating to legal proceedings, approving the operating budget, making certain capital expenditures and the hiring of certain management personnel. Our management agreements that were entered into in connection with the spin-off have terms ranging from 20 to 30 years and allow for one or more renewal periods at the option of our hotel managers. Assuming all renewal periods are exercised by our hotel managers, the total term of our management agreements range from 30 to 70 years. We also have franchise agreements for four hotels that we operate without a management agreement. The franchise agreements have an initial term of 20 years and cannot be extended without the franchisor’s consent. Marketing Fees Additionally, the management and franchise agreements generally require a marketing fee equal to a percentage of rooms revenues. Total marketing fees were $53 million, $55 million and $56 million for the years ended December 31, 2018, 2017 and 2016, respectively, and were included in other departmental and support expense Employee Cost Reimbursements We are responsible for reimbursing our managers for certain employee related costs outside of payroll. These costs include contributions to a defined contribution 401(k) Retirement Savings Plan administered by our managers, union-sponsored pension plans and other post-retirement plans. All of these plans are the responsibility of our managers and our obligation is only for the reimbursement of these costs for individuals who work at our hotel properties. Total employee cost reimbursements were $134 million, $131 million and $130 million for the years ended December 31, 2018, 2017 and 2016, respectively, and were included in the respective operating expenses line item in our consolidated statements of comprehensive income based upon the nature of services provided by such employees.

Net transfers from Parent net transfers (to) from Parent Year Ended December 31, 2017 2016 (in millions) Cash pooling and general financing activities $ (9 ) $ (172 ) Corporate allocations — 66 Income taxes (4 ) 146 Net transfers (to) from Parent $ (13 ) $ 40 Cash Management Hilton uses a centralized approach for cash management. Transfers of cash both to and from Hilton are included within Net transfer from Parent on the consolidated statements of cash flows and consolidated statements of equity. Historically, Hilton has not charged us interest expense and we have not earned interest revenue on our net cash balance due to or from Hilton, respectively. Prior to 2017, cash at certain of our properties secured by our 2013 CMBS loans coupled with our non-wholly owned entities and VIEs (“Restricted Subsidiaries”) would only be transferred to the extent the Restricted Subsidiaries declare a dividend. During the year ended December 31, 2016, the Restricted Subsidiaries paid cash dividends which are presented in the consolidated statements of cash flows and consolidated statements of equity as cash dividends paid to Parent Corporate Allocations Our historical consolidated statements of comprehensive income include allocations of costs from certain corporate and shared functions provided to us by Hilton. Refer to Note 2: “Basis of Presentation and Summary of Significant Accounting Policies” for additional information. During the year ended December 31, 2016 we recognized $66 million of costs within corporate general and administrative Borrowings from Parent In 2015, we borrowed $45 million from Hilton with an interest rate of 1.82%. The note and accrued interest was forgiven in September 2016 and we recognized $45 million as a non-cash contribution from Hilton. Non-cash Distribution to and Contribution from Parent In December 2016, the $450 million loan on the Hilton Orlando Bonnet Creek was repaid in full. We repaid $158 million of the loan and the remaining $292 million was repaid by a wholly owned subsidiary of Hilton and recognized as a non-cash equity contribution from Parent. In September 2016, we distributed interests in entities with ownership interests in the DoubleTree Hotel Missoula/Edgewater and the Hilton Templepatrick Hotel & Country Club to Hilton as these two hotels were not retained by us. The amount of the non-cash equity distribution, representing the carrying value of the assets and liabilities associated with these entities, was $20 million.

Segment Reporting [Abstract]
Geographic and Business Segment Information	Note 15: Geographic and Business Segment Information As of December 31, 2018, we have two operating segments, our consolidated hotels and unconsolidated hotels. Our unconsolidated hotels operating segment does not meet the definition of a reportable segment, thus our consolidated hotels is our only reportable segment. We evaluate our consolidated hotels primarily based on hotel adjusted earnings before interest expense, taxes and depreciation and amortization (“EBITDA”). Hotel Adjusted EBITDA is calculated as EBITDA from hotel operations, adjusted to exclude: • Gains or losses on sales of assets for both consolidated and unconsolidated investments; • Gains or losses on foreign currency transactions; • Share-based compensation expense; • Non-cash impairment losses; and • Other items that we believe are not representative of our current or future operating performance. The following table presents revenues for our consolidated hotels reconciled to our consolidated amounts and Hotel Adjusted EBITDA to net income: Year Ended December 31, 2018 2017 2016 (in millions) Revenues: Total consolidated hotel revenue $ 2,665 $ 2,727 $ 2,704 Other revenues 72 64 23 Total revenues $ 2,737 $ 2,791 $ 2,727 Hotel Adjusted EBITDA $ 761 $ 758 $ 804 Other revenues 72 64 23 Casualty gain (loss) and impairment loss, net 1 (26 ) (15 ) Depreciation and amortization expense (277 ) (288 ) (300 ) Corporate general and administrative expense (65 ) (68 ) (71 ) Other expenses (73 ) (63 ) (19 ) Gain on sales of assets, net 96 1 1 Interest income 6 2 2 Interest expense (127 ) (124 ) (181 ) Equity in earnings from investments in affiliates 18 40 3 (Loss) gain on foreign currency transactions (3 ) (4 ) 3 Income tax (expense) benefit (23 ) 2,346 (82 ) Other gain (loss), net 102 — (25 ) Other items (11 ) (7 ) (4 ) Net income $ 477 $ 2,631 $ 139 The following table presents total assets for our consolidated hotels, reconciled to consolidated amounts: December 31, 2018 2017 (in millions) Consolidated hotels $ 9,305 $ 9,623 All other 58 91 $ 9,363 $ 9,714 The following table presents total revenues and property and equipment, net for each of the geographical areas in which we operate: As of and for the Year Ended December 31, 2018 2017 2016 Revenues Property and Equipment, net Revenues Property and Equipment, net Revenues Property and Equipment, net (in millions) United States (1)(2) $ 2,676 $ 7,906 $ 2,618 $ 8,089 $ 2,580 $ 8,300 All other 61 69 173 222 147 241 $ 2,737 $ 7,975 $ 2,791 $ 8,311 $ 2,727 $ 8,541 (1) Includes revenues of $14 million for the year ended December 31, 2018 and $13 million for each of the years ended December 31, 2017 and 2016 from our laundry operations which is not part of our segment.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 16: Commitments and Contingencies We expect that insurance proceeds, excluding any applicable insurance deductibles, will be sufficient to cover a significant portion of the property damage to our two hotels in Key West, Florida and the Caribe Hilton from Hurricanes Irma and Maria in September 2017 and the resulting loss of business. We have estimated the total amount of damages and insurance proceeds based on all information available to date. As a result, we have recognized a total loss of $16 million representing losses up to the amount of our deductibles; r efer to Note 4: “Property and Equipment.” The amount of the loss for property damage and insurance proceeds could change as more information becomes available about the nature and extent of damage. As of December 31, 2018, we had outstanding commitments under third-party contracts of approximately $34 million for capital expenditures at certain owned and leased hotels. Our contracts contain clauses that allow us to cancel all or some portion of the work. If cancellation of a contract occurred, our commitment would be any costs incurred up to the cancellation date, in addition to any costs associated with the discharge of the contract. We may make certain indemnifications or guarantees to select buyers of our hotels as part of the sale process. In addition, losses related to certain contingent liabilities could be apportioned to us under the distribution and tax matters agreements related to the spin-off transaction. We are involved in litigation arising from the normal course of business, some of which includes claims for substantial sums. We are also involved in litigation that is not in the ordinary course of business, for which we are indemnified under the distribution agreement with Hilton. While the ultimate results of claims and litigation relating to assets retained by Hilton in connection with the spin-off cannot be predicted with certainty, we expect that the ultimate resolution of all pending or threatened claims and litigation as of December 31, 2018 will not have a material effect on our consolidated results of operations, financial position or cash flows.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Principles of Combination and Consolidation	Principles of Combination and Consolidation Subsequent to January 3, 2017, the consolidated financial statements include the accounts of the Company, our wholly owned subsidiaries and entities in which we have a controlling financial interest, including variable interest entities (“VIEs”) where we are the primary beneficiary. The pre-spin consolidated financial statements through January 3, 2017 represent the financial position and results of operations of entities held by us after the spin-off that had historically been under common control of the Parent. The pre-spin consolidated financial statements were prepared on a carve-out basis and reflect significant assumptions and allocations. The consolidated financial statements reflect our financial position, results of operations and cash flows, in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). All significant intercompany transactions and balances within these consolidated financial statements have been eliminated. On October 24, 2007, a predecessor to Hilton became a wholly owned subsidiary of an affiliate of The Blackstone Group L.P. (“Blackstone”) following the completion of a merger (“Merger”). Our consolidated financial statements reflect adjustments made as a result of applying push down accounting at the time of the Merger. The Company’s consolidated financial statements include certain assets and liabilities that have historically been held by Hilton but are specifically identifiable or otherwise attributable to the Company, including goodwill and intangibles.
Allocations	Allocations Through January 3, 2017, the pre-spin consolidated statements of comprehensive income included allocations of corporate general and administrative expenses from Hilton on the basis of financial and operating metrics that Hilton historically used to allocate resources and evaluate performance against its strategic objectives. We considered the basis on which expenses were allocated to be a reasonable reflection of the utilization of services provided to or the benefit received by us during the historical periods presented. However, the allocations may not include all of the actual expenses that would have been incurred by us and may not reflect our consolidated results of operations, financial position and cash flows had we been a stand-alone company during the historical periods presented. Actual costs that might have been incurred had we been a stand-alone company would depend on a number of factors, including the chosen organizational structure, what functions we might have performed ourselves or outsourced and strategic decisions we might have made in areas such as information technology and infrastructure. Following the spin-off, we performed these functions using our own resources or purchased services. For an interim period, some of these functions were provided by Hilton through a transition services agreement (“TSA”). The majority of the services provided pursuant to the TSA were terminated effective January 1, 2018 and the TSA expired on December 31, 2018.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications	Reclassifications Certain line items on the consolidated balance sheet as of December 31, 2017 and on the statements of comprehensive income and statements of cash flows for the years ended December 31, 2017 and 2016 have been reclassified to conform to the current period presentation.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost, and interest applicable to major construction or development projects is capitalized. Costs of improvements that extend the economic life or improve service potential are also capitalized. Capitalized costs are depreciated over their estimated useful lives. Costs for normal repairs and maintenance are expensed as incurred. Depreciation is recorded using the straight-line method over the assets’ estimated useful lives, which are generally as follows: buildings and improvements (8 to 40 years); furniture and equipment (3 to 8 years); and computer equipment and acquired software (3 years). Leasehold improvements are depreciated over the shorter of the estimated useful life, based on the estimates above, or the lease term. We evaluate the carrying value of our property and equipment if there are indicators of potential impairment. We perform an analysis to determine the recoverability of the asset’s carrying value by comparing the expected undiscounted future cash flows to the net book value of the asset. If it is determined that the expected undiscounted future cash flows are less than the net book value of the asset, the excess of the net book value over the estimated fair value is recorded in our consolidated statements of comprehensive income within impairment losses. Fair value is generally estimated using valuation techniques that consider the discounted cash flows of the asset using discount and capitalization rates deemed reasonable for the type of asset, as well as prevailing market conditions, appraisals, recent similar transactions in the market and, if appropriate and available, current estimated net sales proceeds from pending offers. If sufficient information exists to reasonably estimate the fair value of a conditional asset retirement obligation, including environmental remediation liabilities, we recognize the fair value of the obligation when the obligation is incurred, which is generally upon acquisition, construction or development and/or through the normal operation of the asset.
Assets Held for Sale	Assets Held for Sale We classify a property as held for sale when we commit to a plan to sell the asset, the sale of the asset is probable within one year, and it is unlikely that action to complete the sale will change or that the sale will be withdrawn. When we determine that classification of an asset as held for sale is appropriate, we cease recording depreciation for the asset and value the property at the lower of depreciated cost or fair value, less costs to dispose. Further, the related assets and liabilities of the held for sale property will be classified as assets held for sale in our consolidated balance sheets. Any gains on sales of properties are recognized at the time of sale or deferred and recognized in net income (loss)
Investments in Affiliates	Investments in Affiliates The consolidated financial statements include entities in which we have a controlling financial interest, including VIEs where we are the primary beneficiary. The determination of a controlling financial interest is based upon the terms of the governing agreements of the respective entities, including the evaluation of rights held by other interests. If the entity is considered to be a VIE, we determine whether we are the primary beneficiary, and then consolidate those VIEs for which we have determined we are the primary beneficiary. If the entity in which we hold an interest does not meet the definition of a VIE, we evaluate whether we have a controlling financial interest through our voting interests in the entity. We consolidate entities when we own more than 50 percent of the voting shares of a company or otherwise have a controlling financial interest. References in these financial statements to net income (loss) attributable to stockholders We hold investments in affiliates that primarily own or lease hotels. Investments in affiliates over which we exercise significant influence, but lack a controlling financial interest, are accounted for using the equity method. We account for investments using the equity method when we have the ability to exercise significant influence over the entity, typically through a more than minimal investment. Our proportionate share of earnings (losses) from our equity method investments is presented as equity in earnings (losses) from investments in affiliates We assess the recoverability of our equity method investments if there are indicators of potential impairment. If an identified event or change in circumstances requires an evaluation to determine if an investment may have an other-than-temporary impairment, we assess the fair value of the investment based on accepted valuation methodologies, which include discounted cash flows, estimates of sales proceeds and external appraisals. If an investment’s fair value is below its carrying value and the decline is considered to be other-than-temporary, we will recognize an impairment loss in equity in earnings (losses) from investments in affiliates
Non-controlling Interests	Non-controlling Interests We present the portion of any equity that we do not own in entities that we have a controlling financial interest (and thus consolidate) as non-controlling interests and classify those interests as a component of total equity, separate from total stockholders’ equity, on our consolidated balance sheets. For consolidated joint ventures with pro rata distribution allocations, net income or loss is allocated between the joint venture partners based on their respective stated ownership percentages. In addition, we include net income (loss) attributable to the noncontrolling interest in net income (loss)
Goodwill	Goodwill Goodwill represents the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. We do not amortize goodwill, but rather evaluate goodwill for potential impairment on an annual basis or at other times during the year if events or circumstances indicate that the carrying amount may not be recoverable. We have two reporting units, consolidated and unconsolidated hotels, to which goodwill has been allocated. Certain of the entities that are included in our consolidated financial statements were consolidated subsidiaries of our Parent at the time of the Merger. Our Parent allocated goodwill to us based on the relative fair value of our properties compared to that of Parent’s ownership segment as of the date of the Merger. We review the carrying value of goodwill by comparing the carrying value of a reporting unit to its fair value. In any year, we may elect to perform a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is in excess of its carrying value. If we cannot determine qualitatively that the fair value is in excess of the carrying value, or we decide to bypass the qualitative assessment, we proceed to the two-step quantitative process. In the first step, we determine the fair value of the reporting unit. The valuation is based on internal projections of expected future cash flows and operating plans, as well as market conditions relative to the operations of our reporting unit. If the estimated fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired and the second step of the impairment test is not necessary. However, if the carrying amount of the reporting unit exceeds its estimated fair value, then the second step must be performed. In the second step, we estimate the implied fair value of goodwill, which is determined by taking the fair value of the reporting unit and allocating it to all of its assets and liabilities (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, the excess is recognized within casualty (gain) loss and impairment loss, net
Intangible Assets	Intangible Assets Intangible assets with finite useful lives primarily include ground and hotel operating lease contracts recorded by our Parent at the time of the Merger and allocated to us based on either specific identification or the relative fair values as of the date of the Merger. These contract values are based on the present value of the difference between contractual amounts to be paid pursuant to the contracts acquired and the estimate of the fair value of rates for corresponding contracts measured over the period equal to the remaining non-cancelable term of the contract. Intangible assets are amortized using the straight-line method over the remaining non-cancelable term of the contract. We review all finite lived intangible assets for impairment when circumstances indicate that their carrying amounts may not be recoverable. If the carrying value of an asset group is not recoverable, we recognize an impairment loss for the excess of the carrying value over the fair value in our consolidated statements of comprehensive income.
Asset Acquisitions	Asset Acquisitions We consider an asset acquisition to occur when substantially all the fair value of an acquisition is concentrated in a single identifiable asset or a group of similar identifiable assets. In an acquisition of assets, we are not required to expense our acquisition-related costs, and goodwill is not assigned. We will account for the properties purchased as asset acquisitions by allocating the total cash consideration, including transaction costs, to the individual assets acquired and liabilities assumed, respectively, on a relative fair value basis.
Business Combinations	Business Combinations We consider a business combination to occur when we take control of a business by acquiring its net assets or equity interests. We record the assets acquired, liabilities assumed and non-controlling interests at fair value as of the acquisition date, including any contingent consideration. We evaluate factors, including market data for similar assets, expected future cash flows discounted at risk-adjusted rates and replacement cost for the assets to determine an appropriate fair value of the assets. Acquisition-related costs, such as due diligence, legal and accounting fees, are expensed in the period incurred and are not capitalized or applied in determining the fair value of the acquired assets.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include all highly liquid investments with original maturities, when purchased, of three months or less.
Restricted Cash	Restricted Cash Restricted cash includes cash balances established as lender reserves required by our debt agreements. For purposes of our consolidated statement of cash flows, changes in restricted cash caused by changes in lender reserves due to restrictions under our loan agreements are shown as financing activities and changes in deposits for assets we plan to acquire are shown as investing activities.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts An allowance for doubtful accounts is provided on accounts receivable when losses are probable based on historical collection activity and current business conditions.
Fair Value Measurements Valuation Hierarchy	Fair Value Measurements—Valuation Hierarchy Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date (an exit price). We use the three-level valuation hierarchy for classification of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Inputs refer broadly to the assumptions that market participants would use in pricing an asset or liability. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-level hierarchy of inputs is summarized below: • Level 1—Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2—Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the instrument. • Level 3—Valuation is based upon other unobservable inputs that are significant to the fair value measurement. The classification of assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement in its entirety at the end of each reporting period.
Derivative Instruments	Derivative Instruments We may use derivative instruments as part of our overall strategy to manage our exposure to market risks associated with fluctuations in interest rates. We will regularly monitor the financial stability and credit standing of the counterparties to our derivative instruments. Under the terms of certain loan agreements, we may be required to maintain derivative financial instruments to manage interest rates. We do not enter into derivative financial instruments for trading or speculative purposes. We record all derivatives at fair value. On the date the derivative contract is entered, we designate the derivative as one of the following: a hedge of a forecasted transaction or the variability of cash flows to be paid (“cash flow hedge”); a hedge of the fair value of a recognized asset or liability (“fair value hedge”); or an undesignated hedge instrument. Changes in the fair value of a derivative that is qualified, designated and highly effective as a cash flow hedge or net investment hedge are recorded in Other comprehensive income (loss) in the consolidated statements of comprehensive income until they are reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Changes in the fair value of a derivative that is qualified, designated and highly effective as a fair value hedge, along with the gain or loss on the hedged asset or liability that is attributable to the hedged risk, are recorded in current period earnings. Changes in the fair value of undesignated derivative instruments and the ineffective portion of designated derivative instruments are reported in current period earnings. Cash flows from designated derivative financial instruments are classified within the same category as the item being hedged in the consolidated statements of cash flows. Cash flows from undesignated derivative financial instruments are included as an investing activity in our consolidated statements of cash flows. If we determine that we qualify for and will designate a derivative as a hedging instrument, at the designation date we formally document all relationships between hedging activities, including the risk management objective and strategy for undertaking various hedge transactions. This process includes matching all derivatives that are designated as cash flow hedges to specific forecasted transactions and linking all derivatives designated as fair value hedges to specific assets and liabilities in our consolidated balance sheets. To the extent we have designated a derivative as a hedging instrument, each reporting period we assess the effectiveness of our designated hedges in offsetting the variability in the cash flows or fair values of the hedged assets or obligations using the Hypothetical Derivative Method. This method compares the cumulative change in fair value of each hedging instrument to the cumulative change in fair value of a hypothetical hedging instrument, which has terms that identically match the critical terms of the respective hedged transactions. Thus, the hypothetical hedging instrument is presumed to perfectly offset the hedged cash flows. Ineffectiveness results when the cumulative change in the fair value of the hedging instrument exceeds the cumulative change in the fair value of the hypothetical hedging instrument. We discontinue hedge accounting prospectively, when the derivative is not highly effective as a hedge, the underlying hedged transaction is no longer probable, or the hedging instrument expires, is sold, terminated or exercised.
Revenue Recognition	Revenue Recognition Our results of operations primarily consist of room rentals, food and beverage sales and other ancillary goods and services from hotel properties. Other revenues are from our laundry business and service arrangements with Hilton Grand Vacations (“HGV”). Hotel operating revenues are disaggregated into room revenue, food and beverage revenue, ancillary hotel revenue and other revenue on the consolidated statements of comprehensive income to illustrate how economic factors affect the nature, amount and timing, and uncertainty of revenue and cash flows. Rooms revenue is recognized over time when rooms are occupied and food and beverage revenue is recognized at a point in time when goods and services have been delivered or rendered. Ancillary hotel revenue and other revenue is generally recognized at a point in time as goods and services are delivered or rendered. We assess if we are the principal or agent for certain ancillary services provided by third parties. If we are the principal, we recognize revenue based on the gross sales price. If we are the agent, we recognize revenue net of costs paid to service providers. Payment received for a future stay or event is recognized as an advance deposit, which is included in other liabilities
Currency Transactions	Currency Translation The United States dollar (“USD”) is our reporting currency and is the functional currency of our consolidated and unconsolidated entities operating in the U.S. The functional currency for our consolidated and unconsolidated entities operating outside of the U.S. is the currency of the primary economic environment in which the respective entity operates. Assets and liabilities measured in foreign currencies are translated into USD at the prevailing exchange rates in effect as of the financial statement date and the related gains and losses, net of applicable deferred income taxes, are reflected in accumulated other comprehensive income (loss) (loss) gain on foreign currency transactions
Share-based Compensation	Share-based Compensation We recognize the cost of services received in share-based payment transactions with employees and non-employee directors as services are received and recognize a corresponding increase in additional paid-in capital for equity classified awards. We account for any forfeitures when they occur. The measurement objective for these equity awards is the estimated fair value at the grant date of the equity instruments that we will be obligated to issue when employees have rendered the requisite service and satisfied any other conditions necessary to earn the right to benefit from the instruments. The compensation expense for an award classified as an equity instrument is recognized ratably over the requisite service period. The requisite service period is the period during which an employee is required to provide service in exchange for an award.
Income Taxes	Income Taxes We are a REIT for U.S. federal income tax purposes, and we expect to continue to be organized and operate so as to qualify as a REIT. To qualify as a REIT, we must continually satisfy tests concerning, among other things, the real estate qualification of sources of our income, the real estate composition and values of our assets, the amounts we distribute to our stockholders annually and the diversity of ownership of our stock. To the extent we continue to qualify as a REIT, we generally will not be subject to U.S. federal income tax on taxable income generated by our REIT activities that we distribute to our stockholders. Accordingly, no provision for U.S. federal income taxes has been included in our accompanying consolidated financial statements for the years ended December 31, 2018 and 2017 related to our REIT activities, other than the derecognition and remeasurement of deferred tax assets and liabilities associated with our election to be taxed as a REIT and taxes associated with built-in gains related to our assets owned at the date of our spin-off. In addition, we are subject to non-U.S. income tax on foreign held REIT activities. Further, our taxable REIT subsidiaries (“TRSs”) are generally subject to U.S. federal, state and local, and foreign income taxes (as applicable). Through January 3, 2017, we had been included in the consolidated U.S. federal income tax return of Hilton, as well as certain state tax returns where Hilton files on a consolidated or combined basis, and foreign tax returns, as applicable. For purposes of our pre-spin consolidated financial statements, we have recorded deferred tax balances as if we filed tax returns on a stand-alone basis separate from Hilton, but not as a REIT. The separate return method applies the accounting guidance for income taxes to the stand-alone financial statements as if we were a separate taxpayer and a standalone enterprise for the periods presented. The calculation of our income taxes on a separate return basis requires a considerable amount of judgment and use of both estimates and allocations. We believe that the assumptions and estimates used to determine these tax amounts are reasonable. However, our consolidated financial statements may not necessarily reflect what our tax amounts would have been if we had been a stand-alone enterprise during the periods presented. We account for income taxes using the asset and liability method. The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current year, to recognize the deferred tax assets and liabilities that relate to tax consequences in future years, which result from differences between the respective tax basis of assets and liabilities and their financial reporting amounts, and tax loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which the respective temporary differences or operating loss or tax credit carry forwards are expected to be recovered or settled. The realization of deferred tax assets and tax loss and tax credit carry forwards is contingent upon the generation of future taxable income and other restrictions that may exist under the tax laws of the jurisdiction in which a deferred tax asset exists. Valuation allowances are provided to reduce such deferred tax assets to amounts more likely than not to be ultimately realized. We use a prescribed recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return. For all income tax positions, we first determine whether it is “more-likely-than-not” that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. If it is determined that a position meets the more-likely-than-not recognition threshold, the benefit recognized in the financial statements is measured as the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement.

[1]	Fair value for the year ended December 31, 2016, is measured using significant unobservable inputs (Level 3). We estimated fair value of the assets using discounted cash flow analyses, with estimated stabilized growth rates ranging from 1% to 3%, a discounted cash flow term between 10 to 15 years, terminal capitalization rates ranging from 5% to 8% percent, and discount rates ranging from 7% to 10%. The discount and terminal capitalization rates used for the fair value of the assets reflect the risk profile of the market where the property is located and are not necessarily indicative of our hotel portfolio as a whole
[2]	Fair value for the year ended December 31, 2017, was based upon the contracted sales price for a property, less costs to sell, as applicable (Level 2).
