For the majority of our hotel and real estate investments, we consider those control rights to be (i) approval or amendment of developments plans, (ii) financing decisions, (iii) approval or amendments of operating budgets, and (iv) investment strategy decisions. We also evaluate our subsidiaries to determine if they are variable interest entities (“VIEs”). If a subsidiary is a VIE, it is subject to the consolidation framework specifically for VIEs. Typically, the entity that has the power to direct the activities that most significantly impact economic performance consolidates the VIE. We consider an entity to be a VIE if equity investors own an interest therein that does not have the characteristics of a controlling financial interest or if such investors do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. We review our subsidiaries and affiliates at least annually to determine if (i) they should be considered VIEs, and (ii) whether we should change our consolidation determination based on changes in the characteristics thereof. Three partnerships are considered VIE’s, as the general partner maintains control over the decisions that most significantly impact the partnerships. The first VIE is the operating partnership, Host L.P., which is consolidated by Host Inc., of which Host Inc. is the general partner and holds 99% of the limited partner interests. Host Inc.’s sole significant asset is its investment in Host L.P. and substantially all of Host Inc.’s assets and liabilities represent assets and liabilities of Host L.P. All of Host Inc.’s debt is an obligation of Host L.P. and may be settled only with assets of Host L.P. The consolidated partnership that owns the Houston Airport Marriott at George Bush Intercontinental, of which we are the general partner and hold 85% of the partnership interests, also is a VIE. The total assets of this VIE at December 31, 2018 are $48 million and consist primarily of cash and property and equipment. Liabilities for the VIE total $4 million and consist of accounts payable and deferred revenue. The unconsolidated partnership that owns the Philadelphia Marriott Downtown, of which we hold 11% of the limited partner interests, also is a VIE. The carrying amount of this investment at December 31, 2018 is $(6) million and is included in advances to and investments in affiliates. The mortgage debt held by this VIE is non-recourse to us. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents We consider all highly liquid investments with a maturity of three months or less at the date of purchase to be cash equivalents. Property and Equipment Generally, property and equipment is recorded at cost. For properties we develop, cost includes interest and real estate taxes incurred during construction. For property and equipment acquired in a business combination, we record the assets based on their fair value as of the acquisition date. Replacements and improvements and capital leases are capitalized, while repairs and maintenance are expensed as incurred. Properties acquired in an asset acquisition are recorded at cost, allocated using their relative fair values. We capitalize certain inventory (such as china, glass, silver, and linen) at the time of a hotel opening or acquisition, or when significant inventory is purchased (in conjunction with a major rooms renovation or when the number of rooms or meeting space at a hotel is expanded). These amounts then are amortized over the estimated useful life of three years. Subsequent replacement purchases are expensed when placed in service. We maintain a furniture, fixtures and equipment replacement fund for renewal and replacement capital expenditures at our hotels, which generally is funded with 5% of property revenues. Impairment testing. We analyze our consolidated properties for impairment throughout the year when events or circumstances occur that indicate the carrying value may not be recoverable. We test for impairment in several situations, including: • when a property has a current or projected loss from operations; • when it becomes more likely than not that a hotel will be sold before the end of its previously estimated useful life and the anticipated sales price is at or below the book value; or • when other events, trends, contingencies or changes in circumstances indicate that a triggering event has occurred and the carrying value of an asset may not be recoverable . To the extent that a property has a substantial remaining estimated useful life and management does not believe that it is more likely than not that the property will be sold prior to the end thereof, it would be unusual for undiscounted cash flows to be insufficient to recover the property’s carrying value. In the absence of other factors, we assume that the estimated useful life is equal to the remaining GAAP depreciable life because of the continuous property maintenance and improvement capital expenditures required under our management agreements. We adjust our assumptions with respect to the remaining useful life of the property if situations dictate otherwise, such as an expiring ground lease, or that it is more likely than not that the asset will be sold prior to the end of its previously expected useful life. We also consider the effect of regular renewal and replacement capital expenditures on the estimated useful life of our properties, including critical infrastructure, which regularly is maintained and then replaced at the end of its useful life. During 2018, due to a reduction in the estimated hold period of the assets, we impaired four assets, totaling $260 million. No other properties had triggering events warranting impairment testing. During 2017, we recognized impairment expense of $43 million on one property. Impairment expense is included in depreciation and amortization expense. No impairment was recorded in 2016. See Note 13. Fair Value Measurements. Classification of Assets as “Held for Sale”. We will classify a hotel as held for sale when its sale is probable, will be completed within one year and actions to complete the sale are unlikely to change or that the sale will not occur. This policy is consistent with our experience with real estate transactions under which the timing and final terms of a sale frequently are not known until purchase agreements are executed, the buyer has a significant deposit at risk and no financing contingencies exist which could prevent the transaction from being completed in a timely manner. We typically classify assets as held for sale when all the following conditions are met: • Host Inc.’s Board of Directors has approved the sale (to the extent that the dollar amount of the sale requires Board approval); • a binding agreement to sell the property has been signed under which the buyer has committed a significant amount of nonrefundable cash; and • no significant financing contingencies exist which could prevent the transaction from being completed in a timely manner. If these criteria are met, we will cease recording depreciation expense and will record an impairment expense if the fair value less costs to sell is less than the carrying amount of the hotel. We will classify the assets and related liabilities as held for sale on the balance sheet. Gains on sales of properties are recognized at the time of sale or are deferred and recognized as income in subsequent periods as conditions requiring deferral are satisfied or expire without further cost to us. Discontinued Operations. We generally include the operations of a hotel that was sold or a hotel that has been classified as held for sale in continuing operations, including the gain or loss on the sale, unless the sale represents a strategic shift that will have a major impact on our future operations and financial results. Asset retirement obligations. We recognize the fair value of any liability for conditional asset retirement obligations, including environmental remediation liabilities, when incurred, which generally is upon acquisition, construction, or development and/or through the normal operation of the asset, if information exists with which to reasonably estimate the fair value of the obligation. Depreciation and Amortization Expense. We depreciate our property and equipment using the straight-line method. Depreciation expense is based on the estimated useful life of our assets and amortization expense for leasehold improvements is based on the shorter of the lease term or the estimated useful life of the related assets. The useful lives of the assets are based on several assumptions, including cost and timing of capital expenditures to maintain and refurbish the assets, as well as specific market and economic conditions. While management believes its estimates are reasonable, a change in the estimated useful lives could affect depreciation expense and net income (loss) or the gain or loss on the sale of any of our hotels. Intangible Assets and Acquired Liabilities In conjunction with our acquisitions, we may identify intangible assets and other liabilities. These identifiable intangible assets and other liabilities typically include above and below market contracts, including ground and retail leases and management and franchise agreements, which are recorded at fair value in a business combination and at its relative fair value in an asset acquisition. These contract values are based on the present value of the difference between contractual amounts to be paid pursuant to the contracts acquired and our estimate of the fair value of rates for similar contracts measured over the period equal to the remaining non-cancelable term of the contract. Intangible assets and other liabilities are amortized using the straight-line method over the remaining non-cancelable term of the related agreements. Non-Controlling Interests Other Consolidated Partnerships. As of December 31, 2018, we consolidate three majority-owned partnerships that have third-party, non-controlling ownership interests. The third-party partnership interests are included in non-redeemable non-controlling interest-other consolidated partnerships on the consolidated balance sheets and totaled $72 million and $29 million as of December 31, 2018 and 2017, respectively. Approximately $66 million of the balance at December 31, 2018 relates to the partnership that owned the JW Marriott Hotel Mexico City that was sold in 2018, representing the portion of proceeds owed to the third-party interest that was paid in January 2019. Net income attributable to non-controlling interests of consolidated partnerships is included in our determination of net income. Net income attributable to non-controlling interests of third parties was $52 million for the year ended December 31, 2018, and immaterial for each of the years ended December 31, 2017 and 2016. Host Inc.’s treatment of the non-controlling interests of Host L.P. Host Inc. adjusts the non-controlling interests of Host L.P. each period so that the amount presented equals the greater of its carrying value based on its historical cost or its redemption value. The historical cost is based on the proportional relationship between the historical cost of equity held by our common stockholders relative to that of the unitholders of Host L.P. The redemption value is based on the amount of cash or Host Inc. common stock, at our option, that would be paid to the non-controlling interests of Host L.P. if it were terminated. We have estimated that the redemption value is equivalent to the number of shares issuable upon conversion of the OP units currently owned by unaffiliated limited partners (one OP unit may be exchanged for 1.021494 shares of Host Inc. common stock) valued at the market price of Host Inc. common stock at the balance sheet date. Redeemable non-controlling interests of Host L.P. are classified in the mezzanine section of the balance sheet as they do not meet the requirements for equity classification because the redemption feature requires the delivery of registered shares. The table below details the historical cost and redemption values for the non-controlling interests of Host L.P.: As of December 31, 2018 2017 OP units outstanding (millions) 7.5 8.2 Market price per Host Inc. common share $ 16.67 $ 19.85 Shares issuable upon conversion of one OP unit 1.021494 1.021494 Redemption value (millions) $ 128 $ 167 Historical cost (millions) 78 80 Book value (millions) (1) 128 167 ___________ (1) Net income is allocated to the non-controlling interests of Host L.P. based on their weighted average ownership percentage during the period. Net income attributable to Host Inc. has been reduced by the amount attributable to non-controlling interests in Host L.P., which totaled $12 million, $7 million, and $9 million for 2018, 2017, and 2016, respectively. Investments in Affiliates Other-than-Temporary Impairment of an Investment. We perform an analysis on each of our equity method investments for impairment based on the occurrence of triggering events that would indicate that the carrying amount of an investment exceeds its fair value on an other-than-temporary basis. Triggering events can include a decline in distributable cash flows from the investment, a change in the expected useful life or other significant events which would decrease the value of the investment. Our investments primarily consist of joint ventures which own hotels; therefore, generally we will have few observable inputs and will determine fair value based on a discounted cash flow analysis of the investment, as well as consideration of the impact of other elements (i.e. control premiums, etc.). We use certain inputs, such as available third-party appraisals and forecast net operating income for the hotels, to estimate the expected cash flows. If an equity method investment is impaired and that impairment is determined to be other than temporary, an expense is recorded for the difference between the fair value and the carrying amount of the investment. No other-than-temporary impairment expense was recorded in 2018, 2017 and 2016. Distributions from Investments in Affiliates. We classify the distributions from our equity investments in the statements of cash flows based upon an evaluation of the specific facts and circumstances of each distribution. For example, distributions from cash generated by property operations are classified as cash flows from operating activities. However, distributions received because of property sales are classified as cash flows from investing activities. Income Taxes Host Inc. elected to be treated as a REIT effective January 1, 1999, pursuant to the U.S. Internal Revenue Code of 1986, as amended. It is our intention to continue to comply with the REIT qualification requirements and to maintain our qualification for taxation as a REIT. A corporation that elects REIT status and meets certain tax law requirements regarding the distribution of its taxable income to its stockholders as prescribed by applicable tax laws and complies with certain other requirements (relating primarily to the composition of its assets and the sources of its gross income) generally is not subject to federal and state income taxation on its operating income that is distributed to its stockholders. As a partnership for federal income tax purposes, Host L.P. is not subject to federal income tax. Host L.P. is, however, subject to state, local and foreign income and franchise tax in certain jurisdictions. Additionally, each of the Host L.P. taxable REIT subsidiaries is taxable as a regular C corporation, subject to federal, state and foreign income tax. Our consolidated income tax provision includes the income tax provision related to the operations of our taxable REIT subsidiaries, federal and state corporate income taxes on certain items of capital gain generated by Host L.P., and state, local, and foreign income and franchise taxes incurred by Host L.P. and its subsidiaries. Deferred Pursuant to its partnership agreement, Host L.P. generally is required to reimburse Host Inc. for any tax payments it is required to make. Accordingly, the tax information included herein represents disclosures regarding Host Inc. and its subsidiaries. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for net operating loss and capital loss carryovers. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which such amounts are expected to be realized or settled. The effect on deferred tax assets and liabilities from a change in tax rates is recognized in earnings in the period when the new rate is enacted. However, deferred tax assets are recognized only to the extent that it is more likely than not that they will be realized based on consideration of available evidence, including future reversals of existing taxable temporary differences, future projected taxable income and tax planning strategies. GAAP prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return. We must 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. Once it is determined that a position meets the more-likely-than-not recognition threshold, the position is measured at the largest amount of benefit that is greater than 50% likely of being realized upon settlement to determine the amount of benefit to recognize in the financial statements. This accounting standard applies to all tax positions related to income taxes. We recognize any accrued interest related to unrecognized tax benefits in interest expense and penalties in operating expenses. Deferred Charges Financing costs related to long-term debt are deferred and amortized over the remaining life of the debt using the effective interest method. These costs are presented as a direct deduction from the related long-term debt on the balance sheets. Foreign Currency Translation As of December 31, 2018, our international operations consist of hotels located in Brazil and Canada, as well as an investment in an Asia/Pacific joint venture. The financial statements of these hotels and our investments therein are maintained in their functional currency, which generally is the local currency, and their operations are translated to U.S. dollars using the average exchange rates for the period. The assets and liabilities of the hotels and the investments therein are translated to U.S. dollars using the exchange rate in effect at the balance sheet date. The resulting translation adjustments are reflected in other comprehensive income (loss). Foreign currency transactions are recorded in the functional currency for each applicable foreign entity using the exchange rates prevailing at the dates of the transactions. Assets and liabilities denominated in foreign currencies are remeasured at period end exchange rates. The resulting exchange differences are recorded in gain (loss) on foreign currency transactions and derivatives on the accompanying consolidated statements of operations, except when recorded in other comprehensive income (loss) as qualifying net investment hedges. Accumulated Other Comprehensive Income (Loss) The components of total accumulated other comprehensive income (loss) in the balance sheets are as follows (in millions): As of December 31, 2018 2017 Gain on foreign currency forward contracts $ 4 $ 26 Loss on interest rate swap cash flow hedges (4 ) (5 ) Foreign currency translation (60 ) (83 ) Other comprehensive loss attributable to non-controlling interests 1 2 Total accumulated other comprehensive loss $ (59 ) $ (60 ) During , Revenues Substantially all of our operating results represent revenues and expenses generated by property-level operations. Payments are due from customers when services are provided to them. Due to the short-term nature of our contracts and the almost concurrent receipt of payment, we have no material unearned revenue at year end. We collect sales, use, occupancy and similar taxes at our hotels, which we present on a net basis (excluded from revenues) on our statements of operations. Revenues are recognized, as follows: Income statement line item Recognition method Rooms revenues Rooms revenues represent revenues from the occupancy of our hotel rooms and are driven by the occupancy and average daily rate charged. Rooms revenues do not include ancillary services or fees charged. The contracts for room stays with customers generally are very short term in duration and revenues are recognized over the course of the hotel stay. Food and beverage revenues Food and beverage revenues consist of revenues from group functions, which may include banquet revenues and audio-visual revenues, as well as outlet revenues from the restaurants and lounges at our properties. Revenues are recognized as the services or products are provided. Our hotels may employ third parties to provide certain services at the property, for example, audio and visual services. We evaluate each of these contracts to determine if the hotel is the principal or the agent in the transaction and record the revenues as appropriate (i.e. gross vs. net). Other revenues Other revenues consist of ancillary revenues at the property, including attrition and cancelation fees, golf courses, resort and destination fees, spas, entertainment and other guest services, as well as rental revenues; primarily consisting of leased retail outlets. Other revenues generally are recognized as the services or products are provided. Attrition and cancelation fees are recognized for non-cancelable deposits when the customer provides notification of cancelation or is a no-show for the specified date, whichever comes first. Fair Value In evaluating the fair value of both financial and non-financial assets and liabilities, GAAP outlines a valuation framework and creates a fair value hierarchy that distinguishes between market assumptions based on market data (“observable inputs”) and a reporting entity’s own assumptions about market data (“unobservable inputs”). Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability at the measurement date in an orderly transaction (an “exit price”). Assets and liabilities are measured using inputs from three levels of the fair value hierarchy. The three levels are as follows: Level 1 — Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date. An active market is defined as a market in which transactions occur with sufficient frequency and volume to provide pricing on an ongoing basis. Level 2 — Inputs include quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active (markets with few transactions), inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data correlation or other means. Level 3 — Unobservable inputs reflect our assumptions about the pricing of an asset or liability when observable inputs are not available. Earnings Per Common Share (Unit) Basic earnings per common share (unit) is computed by dividing net income attributable to common stockholders (unitholders) by the weighted average number of shares of Host Inc. common stock or Host L.P. common units outstanding. Diluted earnings per common share (unit) is computed by dividing net income attributable to common stockholders (unitholders), as adjusted for potentially dilutive securities, by the weighted average number of shares of Host Inc. common stock or Host L.P. common units outstanding plus other potentially dilutive securities. Dilutive securities may include shares granted under comprehensive stock plans or the common OP units distributed to Host Inc. to support such shares granted, and other non-controlling interests that have the option to convert their limited partner interests to common OP units and convertible debt securities. No effect is shown for any securities that are anti-dilutive. The calculation of Host Inc. basic and diluted earnings per common share is shown below (in millions, except per share amounts): Year ended December 31, 2018 2017 2016 Net income $ 1,151 $ 571 $ 771 Less: Net income attributable to non-controlling interests (64 ) (7 ) (9 ) Net income attributable to Host Inc. $ 1,087 $ 564 $ 762 Basic weighted average shares outstanding 739.8 738.6 743.0 Assuming distribution of common shares granted under the comprehensive stock plans, less shares assumed purchased at market 0.8 0.5 0.7 Diluted weighted average shares outstanding 740.6 739.1 743.7 Basic earnings per common share $ 1.47 $ .76 $ 1.03 Diluted earnings per common share $ 1.47 $ .76 $ 1.02 The calculation of Host L.P. basic and diluted earnings per common unit is shown below (in millions, except per unit amounts): Year ended December 31, 2018 2017 2016 Net income $ 1,151 $ 571 $ 771 Less: Net income attributable to non-controlling interests (52 ) — — Net income attributable to Host L.P. $ 1,099 $ 571 $ 771 Basic weighted average units outstanding 732.2 731.5 736.3 Assuming distribution of common units to support shares granted under the comprehensive stock plans, less shares assumed purchased at market 0.8 0.5 0.6 Diluted weighted average units outstanding 733.0 732.0 736.9 Basic earnings per common unit $ 1.50 $ .78 $ 1.05 Diluted earnings per common unit $ 1.50 $ .78 $ 1.05 Share-Based Payments At December 31, 2018, Host Inc. maintained two stock-based employee compensation plans. Upon the issuance of Host’s common stock under the compensation plans, Host L.P. will issue to Host Inc. common OP units of an equivalent value. These liabilities are included in the consolidated financial statements for Host Inc. and Host L.P. We recognize costs resulting from Host Inc.’s share-based payment transactions over their vesting periods. We classify share-based payment awards granted in exchange for employee services either as equity-classified awards or liability-classified awards. Equity-classified awards are measured based on the fair value on the date of grant. Liability-classified awards are remeasured to fair value each reporting period. Effective January 1, 2017, we implemented a new stock-based employee compensation plan. In conjunction with the adoption of ASU No. 2016-09, the awards under the new plan are classified as equity. The plan includes awards that vest over a one-year, two-year and three-year period. For performance-based awards, compensation cost will be recognized when the achievement of the performance condition is considered probable. If a performance condition has more than one outcome that is probable, recognition of compensation cost will be based on the condition that is the most likely outcome. No compensation cost is recognized for awards for which employees do not render the requisite services. Concentrations of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents. We are exposed to credit risk with respect to cash held at various financial institutions and access to our credit facility, however, this cash balance is spread among a diversified group of investment grade financial institutions. Acquisitions and When acquiring an asset, we determine whether the acquisition is an asset acquisition or business combination based on whether the fair value of the gross assets acquired is concentrated in a single (group of similar) identifiable assets, resulting in an asset acquisition or not, resulting in a business combination. If an asset acquisition, the asset is recorded in accordance with our property and equipment policy and related acquisition costs are capitalized as part of the asset. In a business combination, we recognize identifiable assets acquired, liabilities assumed, and non-controlling interests at their fair values at the acquisition date based on the exit price (i.e. the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date). We evaluate several factors, including market data for similar assets, expected cash flows discounted at risk adjusted rates and replacement cost for the assets to determine an appropriate exit cost when evaluating the fair value of our assets and liabilities acquired. Property and equipment are recorded at fair value and such fair value is allocated to buildings, improvements, furniture, fixtures and equipment using appraisals and valuations performed by management and independent third parties. Acquisition-related costs, such as due diligence, legal and accounting fees, are not capitalized or applied in determining the fair value of the acquired assets. Other items that we evaluate in a business combination include identifiable intangible assets, capital lease assets and obligations and goodwill. Identifiable intangible assets typically consist of assumed contracts, including ground and retail leases and management and franchise agreements, which are recorded at fair value. Capital lease obligations that are assumed as part of the acquisition of a leasehold interest are measured at fair value and are included as debt on the accompanying balance sheet and we record the corresponding right-to-use assets. Classification of a lease does not change if it is part of a business combination. In making estimates of fair values for purposes of allocating purchase price, we may utilize a number of sources that arise in connection with the acquisition or financing of a property and other market data, including third-party appraisals and valuations. In certain situations, and usually only in connection with the acquisition of a foreign hotel, a deferred tax liability is recognized due to the difference between the fair value and the tax basis of the acquired assets at the acquisition date. Any consideration paid in excess of the net fair value of the identifiable assets and liabilities acquired would be recor

Investments in Affiliates	4. Investments in Affiliates We own investments in joint ventures for which the equity method of accounting is used. The debt of our joint ventures is non-recourse to, and not guaranteed by, us, and a default of such debt does not trigger a default under any of our debt instruments. We carry our investments at historical cost, which due to debt restructuring or distributions, may result in a negative investment balance. However, the negative balances due not represent obligations for us or the partners. Investments in affiliates consist of the following (in millions): As of December 31, 2018 Ownership Interests Our Investment Our Portion of Debt Total Debt Distributions received in 2018 (1) Assets Asia/Pacific JV 25 % $ 14 $ — $ — $ — A 36% interest in seven hotels in India Maui JV 67 % 70 22 32 17 131-unit vacation ownership project in Maui, HI Hyatt Place JV 50 % (13 ) 30 60 3 One hotel in Nashville, TN Harbor Beach JV 49.9 % (30 ) 75 150 8 One hotel in Fort Lauderdale, FL Philadelphia Marriott Downtown JV 11 % (6 ) 23 213 2 One hotel in Philadelphia, PA Other investments 13 — — — Total $ 48 $ 150 $ 455 $ 30 As of December 31, 2017 Ownership Interests Our Investment Our Portion of Debt Total Debt Distributions received in 2017 (1) Assets Euro JV (2) (3) 32.1 - 33.4% $ 271 $ 316 $ 1,029 $ 31 Eleven hotels in Europe Asia/Pacific JV 25 % 15 — — — A 36% interest in seven hotels in India Maui JV 67 % 83 27 41 7 131-unit vacation ownership project in Maui, HI Hyatt Place JV 50 % (13 ) 30 60 3 One hotel in Nashville, TN Harbor Beach JV 49.9 % (28 ) 75 149 7 One hotel in Fort Lauderdale, FL Philadelphia Marriott Downtown JV 11 % (6 ) 24 217 1 One hotel in Philadelphia, PA Other investments 5 — — — Total $ 327 $ 472 $ 1,496 $ 49 ___________ (1) Distributions received were funded by cash from operations unless otherwise noted. (2) Our interests in the Euro JV were sold in December 2018. (3) Distributions received from Euro JV in 2017 include $9 million of loan refinancing proceeds. European Joint Venture On December 21, 2018 we sold our approximate one-third interest in the Euro JV to the existing partners thereof, APG Strategic Real Estate Pool NV, an affiliate of a Dutch Pension Fund, and Jasmine Hotels Pte Ltd, an affiliate of the real estate investment company of the Government of Singapore Investment Corporation Pte Ltd (“GIC RE”). We received net proceeds of approximately €435 million ($496 million) and recorded a gain on sale of approximately $238 million. A portion of the proceeds was used to repay the €207 million ($237 million) draw on the credit facility. Asia/Pacific Joint Venture We own a 25% interest in the Asia/Pacific JV, the other owner of which is RECO Hotels JV Private Limited, an affiliate of the Government of Singapore Investment Corporation Pte Ltd. The Asia/Pacific JV may be terminated by the owners at any time. Due to the ownership structure and the substantive participating rights of the non-Host owner, including approval over financing, acquisitions and dispositions, and annual operating and capital expenditures budgets, the Asia/Pacific JV is not consolidated in our financial statements. The commitment period for the equity contributions to the joint venture has expired. Certain funding commitments remain, however, related to its existing investment in India. As of December 31, 2018, the Asia/Pacific JV has invested approximately $106 million (of which our share is $27 million) in a joint venture in India with Accor S.A. and InterGlobe Enterprises Limited, in which the Asia/Pacific JV holds a 36% interest. On November 12, 2017, the joint venture opened the Novotel & ibis Chennai OMR. Maui Joint Venture We have a 67% non-controlling interest in a joint venture that owns a 131-unit vacation ownership development in Maui, Hawaii adjacent to our Hyatt Regency Maui Resort & Spa (the “Maui JV”). The project opened in December 2014. During 2017, the Maui JV repaid its outstanding construction loan, releasing us of our guarantees. Additionally, the joint venture has $32 million of outstanding debt used to facilitate the sales of the vacation ownership units, which is not guaranteed by us. Hyatt Place Joint Venture We own a 50% interest in a joint venture with White Lodging Services that owns the 255-room Hyatt Place Nashville Downtown in Tennessee. The Hyatt Place joint venture has an outstanding $60 million mortgage loan due August 2019, with two 12-month extension options. The loan bears interest at 1-month USD LIBOR plus 300 basis points, or 5.5%, at December 31, 2018. Harbor Beach Joint Venture We have a non-controlling 49.9% interest in a joint venture with R/V-C Association that owns the 650-room Fort Lauderdale Marriott Harbor Beach Resort & Spa in Florida. The joint venture has a $150 million mortgage loan with a maturity date of January 1, 2024. The loan bears interest at 4.75%. Only monthly interest payments are being made on the loan. No principal payments are due until the loan matures.

Under the terms of our senior notes indenture, our senior notes are equal in right of payment with all of our unsubordinated indebtedness and senior to all our subordinated obligations. The face amount of our senior notes at both December 31, 2018 and 2017 was $2.8 billion. The senior notes balances as of December 31, 2018 and 2017 are net of unamortized discounts and deferred financing costs of approximately $18 million and $22 million, respectively. We pay interest on each series of our senior notes semi-annually in arrears at the respective annual rates indicated in the table above. Under the terms of the senior notes indenture, our ability to incur indebtedness and pay dividends is subject to restrictions and the satisfaction of various conditions. As of December 31, 2018, we are in compliance with all of these covenants. On March 20, 2017, we issued $400 million of 3.875% Series G senior notes due April 2024 for proceeds of approximately $395 million, net of discounts, underwriting fees and expenses. Interest is payable semi-annually in arrears on May 15 and November 15, commencing November 15, 2017. The net proceeds were used to repay $250 million that had been drawn under the revolver portion of our credit facility and for general corporate purposes. Authorization for Repurchase of Senior Notes. In February 2019, Host Inc.’s Board of Directors authorized repurchases of up to $250 million of senior notes (other than in accordance with their terms). No repurchases occurred in 2018. Credit Facility. On May 31, 2017 we entered into the fourth amended and restated senior revolving credit facility with Bank of America, N.A., as administrative agent, JPMorgan Chase Bank, N.A., as syndication agent, and certain other agents and lenders. The credit facility allows for revolving borrowings in an aggregate principal amount of up to $1 billion, including a foreign currency subfacility for Canadian dollars, Australian dollars, Euros, British pound sterling and, if available to the lenders, Mexican pesos, of up to the foreign currency equivalent of $500 million, subject to a lower amount in the case of Mexican peso borrowings. The credit facility also provides for the existing term loan facility of $1 billion (which is fully utilized), a subfacility of up to $100 million for swingline borrowings in U.S. dollars, Canadian dollars, Euros and British pound sterling and a subfacility of up to $100 million for issuances of letters of credit. Host L.P. also has the option to increase the aggregate principal amount of the credit facility by up to $500 million, subject to obtaining additional loan commitments and satisfaction of certain conditions. The revolving credit facility has an initial scheduled maturity date of May 2021, with the option for Host L.P. to extend the term for two additional six-month terms, subject to certain conditions, including the payment of an extension fee and the accuracy of representations and warranties, and $500 million of term loans (“2017 Term Loan”) have an initial scheduled maturity of May 2021, with an option for Host L.P. to extend the term for one additional year, subject to similar conditions. We pay interest on revolver borrowings under the credit facility at floating rates equal to LIBOR plus a margin ranging from 82.5 to 155 basis points (depending on Host L.P.’s unsecured long-term debt rating). We also pay a facility fee ranging from 12.5 to 30 basis points, depending on our rating and regardless of usage. Based on Host L.P.’s unsecured long-term debt rating as of December 31, 2018, we are able to borrow at a rate of LIBOR plus 100 basis points and pay a facility fee of 20 basis points. On September 10, 2015, we closed on a $500 million term loan (“2015 Term Loan”) by exercising the accordion feature of our existing credit facility. On that same day, we drew $300 million on the 2015 Term Loan and the remaining $200 million on December 29, 2015. The proceeds were used to repay outstanding amounts on the revolver. The loan has a five-year maturity and its interest rate spread depends on our unsecured debt rating. Based on our unsecured debt rating at December 31, 2018, both the 2017 Term Loan and 2015 Term Loan have a floating interest rate of LIBOR plus 110 bps (or approximately a 3.6% all-in interest rate). Net repayments under the credit facility were $102 million and $55 million in 2018 and 2017, respectively. As of December 31, 2018, we have $945 million of available capacity under the revolver portion of our credit facility. Financial Covenants . The credit facility contains covenants concerning allowable leverage, fixed charge coverage and unsecured interest coverage (as defined in our credit facility). Currently, we are permitted to borrow and maintain amounts outstanding under the credit facility so long as our leverage ratio is not in excess of 7.25x, our unsecured coverage ratio is not less than 1.75x and our fixed charge coverage ratio is not less than 1.25x. The financial covenants for the credit facility do not apply when there are no borrowings thereunder. Therefore, so long as there are no amounts outstanding, we would not be in default if we do not satisfy the financial covenants and we do not lose the potential to draw under the credit facility in the future if we were to regain compliance with the financial covenants. These calculations are performed based on pro forma results for the prior four fiscal quarters, giving effect to transactions such as acquisitions, dispositions and financings as if they had occurred at the beginning of the period. Under the terms of the credit facility, interest expense excludes items such as gains and losses on the extinguishment of debt, deferred financing costs related to the senior notes or the credit facility, amortization of debt premiums or discounts that were recorded at issuance of a loan in order to establish the debt at fair value and non-cash interest expense due to the implementation in 2009 of accounting standards related to our exchangeable debentures, all of which are or have been included in interest expense on our consolidated statements of operations. Additionally, total debt used in the calculation of our leverage ratio is based on a “net debt” concept, under which cash and cash equivalents in excess of $100 million are deducted from our total debt balance. As of December 31, 2018, we are in compliance with the financial covenants under our credit facility. Guarantees . The credit facility requires all Host L.P. subsidiaries which guaranty Host L.P. debt to similarly guarantee obligations under the credit facility but otherwise removed the requirement under the prior agreement that guarantees and pledges are required in the event that Host L.P.’s leverage ratio exceeds 6.0x for two consecutive fiscal quarters at a time when Host L.P. does not have an investment grade long-term unsecured debt rating. Other Covenants and Events of Default . The credit facility contains restrictive covenants on customary matters. Certain covenants are less restrictive at any time that our leverage ratio is below 6.0x. In particular, at any time that our leverage ratio is below 6.0x, we will not be subject to limitations on capital expenditures, and the limitations on acquisitions, investments and dividends contained in the credit facility will be superseded by the generally less restrictive corresponding covenants in our senior notes indenture. Additionally, the credit facility’s restrictions on the incurrence of debt and the payment of dividends generally are consistent with our senior notes indenture for our Series D senior notes. These provisions, under certain circumstances, limit debt incurrence to debt incurred under the credit facility or in connection with a refinancing, and limit dividend payments to those necessary to maintain Host Inc.’s tax status as a REIT. Our senior notes and credit facility have cross default provisions that would trigger a default under those agreements if we were to have a payment default or an acceleration prior to maturity of other debt of Host L.P. or its subsidiaries. The amount of other debt in default needs to exceed certain thresholds in order to trigger a cross default and the thresholds are greater for secured debt than for unsecured debt. The credit facility also includes usual and customary events of default for facilities of this nature, and provides that, upon the occurrence and continuance of an event of default, payment of all amounts owed under the credit facility may be accelerated, and the lenders’ commitments may be terminated. In addition, upon the occurrence of certain insolvency or bankruptcy related events of default, all amounts owed under the credit facility will become due and payable and the lenders’ commitments will terminate.

Equity [Abstract]
Equity of Host Inc. and Capital of Host L.P.	6. Equity of Host Inc. and Capital of Host L.P. Equity of Host Inc. Host Inc. has authorized 1,050 million shares of common stock, with a par value of $0.01 per share, of which 740.4 million and 739.1 million were outstanding as of December 31, 2018 and 2017, respectively. Fifty million shares of no par value preferred stock are authorized; none of such preferred shares was outstanding as of December 31, 2018 and 2017. Capital of Host L.P. As of December 31, 2018, Host Inc. is the owner of approximately 99% of Host L.P.’s common OP units. The remaining 1% of Host L.P.’s common OP units are held by various unaffiliated limited partners. Each common OP unit may be redeemed for cash or, at the election of Host Inc., Host Inc. common stock, based on the conversion ratio of 1.021494 shares of Host Inc. common stock for each OP unit. In connection with the issuance of shares by Host Inc., Host L.P. will issue OP units based on the same conversion ratio. As of December 31, 2018 and 2017, Host L.P. had 732.4 million and 731.7 million OP units outstanding, respectively, of which Host Inc. held 724.8 million and 723.5 million, respectively. Repurchases and Issuances of Common Stock and Common OP Units Pursuant to a distribution agreement entered into in May 2018, we may issue and sell, from time to time, shares of common stock having a combined aggregate offering price of up to $500 million. Additionally, in February 2017, the Board of Directors authorized a program to repurchase up to $500 million of common stock . Dividends/Distributions Host Inc. is required to distribute at least 90% of its annual taxable income, excluding net capital gains, to its stockholders in order to maintain its qualification as a REIT. Funds used by Host Inc. to pay dividends on its common stock are provided by distributions from Host L.P. The amount of any future dividends will be determined by Host Inc.’s Board of Directors. The dividends that were taxable to our stockholders in 2018 were considered 99.7% ordinary income, and 0.3% unrecaptured Section 1250 gain. The 2018 ordinary income dividends are eligible for the 20% deduction provided by Section 199A for qualified REIT dividends. The dividends that were taxable to our stockholders in 2017 were considered 88% ordinary income (non-qualified dividend income), 1% qualified dividend income, 8% capital gain distribution and 3% unrecaptured Section 1250 gain. The table below presents the amount of common dividends declared per share and common distributions per unit as follows: Year ended December 31, 2018 2017 2016 Common stock $ .85 $ .85 $ .85 Common OP units .868 .868 .868 On February 19, 2019, Host Inc.’s Board of Directors authorized a regular quarterly cash dividend of $0.20 per share on Host Inc.’s common stock.

Income Tax Disclosure [Abstract]
Income Taxes	7. Income Taxes We elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code commencing with our taxable year beginning January 1, 1999. To qualify as a REIT, we must meet a number of organizational and operational requirements, including a requirement that we distribute at least 90% of our taxable income to our stockholders, excluding net capital gain. As a REIT, generally we will not be subject to federal and state corporate income tax on that portion of our taxable income that currently is distributed to our stockholders. If we fail to qualify for taxation as a REIT in any taxable year, we will be subject to federal and state corporate income taxes at regular corporate rates and may not be able to qualify as a REIT for four subsequent taxable years. Even if we qualify for taxation as a REIT, we may be subject to certain state, local and foreign taxes on our income and property, and to federal and state income and excise taxes on our undistributed taxable income. Our 2018 tax provision includes approximately $77 million of U.S. federal and state corporate income tax that we paid on long-term capital gain generated in 2018 that we chose to retain rather than distribute to our stockholders. We have recorded a 100% valuation allowance of approximately $9 million against the deferred tax asset related to our domestic capital loss carryover as of December 31, 2018. The net decrease of our valuation allowance for the year ending December 31, 2018 is approximately $16 million from the year ending December 31, 2017. The primary components of our net deferred tax assets are as follows (in millions): As of December 31, 2018 2017 Deferred tax assets Net operating loss and capital loss carryovers $ 17 $ 34 Property and equipment 3 3 Deferred revenue and expenses 23 27 Foreign exchange net losses (AOCI) 12 12 Total gross deferred tax assets 55 76 Less: Valuation allowance (11 ) (27 ) Total deferred tax assets, net of valuation allowance $ 44 $ 49 Deferred tax liabilities Investments in domestic affiliates (5 ) (8 ) Total gross deferred tax liabilities (5 ) (8 ) Net deferred tax assets $ 39 $ 41 At December 31, 2018, we have aggregate gross domestic and foreign net operating loss and capital loss carryovers of approximately $60 million. We have deferred tax assets related to these domestic and foreign loss carryovers of approximately $17 million, with a valuation allowance of approximately $11 million. Our Canadian net operating loss carryovers expire through 2035, and our Canadian capital loss carryover has no expiration date. Our domestic capital loss carryover expires in 2023. Our Brazil net operating loss carryovers have no expiration date. We believe that it is more likely than not that the results of future operations will generate sufficient taxable income in order to realize our total deferred tax assets, net of a valuation allowance of $11 million, of $44 million. Our U.S. and foreign income from continuing operations before income taxes was as follows (in millions): Year ended December 31, 2018 2017 2016 U.S. income $ 887 $ 593 $ 763 Foreign income 414 58 48 Total $ 1,301 $ 651 $ 811 The provision for income taxes from continuing operations consists of (in millions): Year ended December 31, 2018 2017 2016 Current —Federal $ 79 $ 17 $ — —State 30 6 1 —Foreign 37 19 12 146 42 13 Deferred —Federal 2 32 24 —State 1 4 6 —Foreign 1 2 (3 ) 4 38 27 Income tax provision – continuing operations $ 150 $ 80 $ 40 The differences between the income tax provision calculated at the statutory U.S. federal income tax rate of 21% in 2018 (35% in 2017 and 2016) and the actual income tax provision recorded for continuing operations are as follows (in millions): Year ended December 31, 2018 2017 2016 Statutory federal income tax provision $ 273 $ 228 $ 284 Adjustment for nontaxable income of Host Inc.

A reconciliation of the beginning and ending balances of our unrecognized tax benefits is as follows (in millions): 2018 2017 Balance at January 1 $ 11 $ 11 Balance at December 31 $ 11 $ 11 All of such uncertain tax position amounts, if recognized, would impact our reconciliation between the income tax provision calculated at the statutory U.S. federal income tax rate of 21% (35% in 2017) and the actual income tax provision recorded each year. We expect a decrease to the balance of unrecognized tax benefits within 12 months of the reporting date of approximately $3 million. As of December 31, 2018, the tax years that remain subject to examination by major tax jurisdictions generally include 2015-2018. There were no material interest or penalties recorded for the years ended December 31, 2018, 2017, and 2016.

Leases [Abstract]
Leases	8. Leases Taxable REIT Subsidiaries Leases We lease substantially all of our hotels to a wholly owned subsidiary that qualifies as a taxable REIT subsidiary due to federal income tax restrictions on a REIT’s ability to derive revenue directly from the operation and management of a hotel. Ground Leases As of December 31, 2018, all or a portion of 25 of our hotels are subject to ground leases, generally with multiple renewal options, all of which are accounted for as operating leases. For lease agreements with scheduled rent increases, we recognize the fixed portion of the lease expense ratably over the term of the lease. Certain of these leases contain provisions for the payment of contingent rentals based on a percentage of sales in excess of stipulated amounts. Other Lease Information We also have leases on facilities used in our former restaurant business, all of which we subsequently subleased. These leases and subleases contain one or more renewal options, generally for five- or ten-year periods. The restaurant leases are accounted for as operating leases. Our contingent liability related to these leases is $7 million as of December 31, 2018. We, however, consider the likelihood of any material funding related to these leases to be remote. Our leasing activity also includes those entered into by our hotels for various types of equipment, such as computer equipment, vehicles and telephone systems. Equipment leases are accounted for either as operating or capital leases, depending upon the characteristics of the particular lease arrangement. Equipment leases that are characterized as capital leases are classified as furniture and equipment and are depreciated over the life of the lease. The amortization expense applicable to capitalized leases is included in depreciation expense. The following table presents the future minimum annual rental commitments required under non-cancelable operating leases for which we are the lessee (in millions): As of December 31, 2018 2019 $ 46 2020 44 2021 43 2022 40 2023 37 Thereafter 1,309 Total minimum lease payments $ 1,519 Minimum payments for the operating leases have not been reduced by aggregate minimum sublease rentals from restaurants of approximately $6 million that are payable to us under non-cancelable subleases.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Employee Stock Plans	9. Employee Stock Plans Upon the issuance of Host Inc.’s common stock under either of the two stock-based compensation plans described below, Host L.P. will issue to Host Inc. common OP units of an equivalent value. Accordingly, these awards and related disclosures are included in both Host Inc.’s and Host L.P.’s consolidated financial statements. Host Inc. maintains two stock-based compensation plans, the Comprehensive Stock and Cash Incentive Plan (the “2009 Comprehensive Plan”), under which Host Inc. may award to participating employees restricted stock units (“RSUs”), and the Employee Stock Purchase Plan. At December 31, 2018, there were approximately 13 million shares of Host Inc.’s common stock reserved and available for issuance under the 2009 Comprehensive Plan. We recognize costs resulting from share-based payments in our financial statements over their vesting periods. No compensation cost is recognized for awards for which employees do not render the requisite services. We classify share-based payment awards granted in exchange for employee services as either equity-classified or liability-classified awards. Equity-classified awards are measured based on their fair value as of the date of grant. In contrast, liability-classified awards are re-measured to fair value each reporting period. During 2018, 2017 and 2016, we recorded stock-based compensation expense of approximately $14 million, $11 million and $12 million, respectively. Shares granted in 2018, 2017 and 2016 totaled 1.2 million, 1.5 million and 2.3 million, respectively, while 0.8 million, 0.6 million and 1.2 million shares, respectively, vested during those years. Senior Executive Plan During 2018, Host Inc. granted 1.1 million RSU awards under the 2009 Comprehensive Plan, which amount represents the maximum number of RSUs that can be earned during the period of 2018 through 2020 if performance is at the “high” level of achievement and, for time based awards, the executive remains employed. The RSUs vest over a one, two or three-year period and 0.9 million RSUs were unvested at December 31, 2018. Total unrecognized compensation cost related to unvested RSU awards that vest through 2020 is approximately $9 million. Prior to 2017, all restricted stock awards were fully vested. RSU awards Vesting of RSUs awarded in 2018 is based on (1) continued employment on the vesting date (“Time-Based Award”); (2) the achievement of relative total shareholder return (“TSR”); and (3) our performance against certain annual strategic objectives. Approximately 33% of the RSUs are Time-Based Awards and vest on an annual basis over three years; approximately 33% of the RSUs are based on the satisfaction of the TSR compared to (i) the NAREIT index, (ii) the Standard & Poor’s index, and (iii) a Selected Lodging Company index that serves as a relevant industry/asset specific measurement to our competitors and vest following a three year performance period; and the remaining 34% are based on our performance against certain strategic objectives and vest on an annual basis. The RSUs granted are considered equity-classified awards. As a result, the fair value of these awards is based on the fair value on the grant date, and such grant date fair value is not adjusted for subsequent movements thereof. We value the time based awards using the closing stock price on the grant date multiplied by the percentage of shares expected to be released, which is 100% of the time based awards. We also value the strategic objective awards using the closing stock price on the grant date multiplied by the percentage of shares expected to be released; however, as a result of the strategic objective awards’ performance conditions, we reevaluate the percentage based on the probability of meeting the performance conditions each period. We value the TSR awards using the economic theory 2018 Award Grants NAREIT index Standard & Poor's index Selected Lodging Company index Grant date stock price $ 18.75 $ 18.75 $ 18.75 Volatility 26.2 % 26.2 % 26.2 % Beta 1.149 1.214 1.016 Risk-free rate - three year award 2.32 % 2.32 % 2.32 % 2017 Award Grants NAREIT index Standard & Poor's index Selected Lodging Company index Grant date stock price $ 18.56 $ 18.56 $ 18.56 Volatility 25.2 % 25.2 % 25.2 % Beta 1.178 1.182 1.006 Risk-free rate - one year award 0.82 % 0.82 % 0.82 % Risk-free rate - two year award 1.20 % 1.20 % 1.20 % Risk-free rate - three year award 1.48 % 1.48 % 1.48 % In making these assumptions, we base the expected volatility on the historical volatility over three years using daily stock price observations. The beta is calculated by comparing the risk of our stock to the risk of the applicable peer group index, using three years of daily price data. We base the risk-free rate on the Treasury bond yields corresponding to the length of each performance period as reported by the Federal Reserve.

Accordingly, the 0.3 million shares issued in 2018 include shares vested at December 31, 2017, after adjusting for shares withheld to meet employee tax requirements. The shares withheld for employee tax requirements were valued at $4.8 million, $4.9 million and $2.4 million for 2018, 2017 and 2016, respectively. Stock Option Awards Beginning in 2017, we no longer grant stock option awards as part of the 2009 Comprehensive Plan. As of December 31, 2018, 0.4 million shares of stock option awards were outstanding and exercisable, with a weighted average remaining life of 6 years and a weighted average exercise price of $19.35 per share. During 2018, 2017 and 2016, we received proceeds of $3 million, $7 million and $4 million, respectively, from the exercise of stock options. During 2016, stock option compensation expense was $1.5 million and all stock option awards outstanding are fully vested. Other Stock Plans In addition to the share-based plans described above, we maintain an upper-middle management plan and an employee stock purchase plan. The upper-middle management awards are time-based, equity-classified awards that vest within three years of the grant date and compensation expense is recognized over the life of the award based on the grant date fair value. Through the employee stock purchase plan, employees can purchase stock at a discount of 10% of the lower of the beginning and ending stock price each quarter. During 2018, 2017 and 2016, we granted 136,000 shares, 69,000 shares and 118,000 shares, respectively, under both of these programs and recorded expense of $1.9 million, $1.7 million and $1.6 million, respectively.

Dispositions	11. Dispositions We disposed of four hotels in 2018, four hotels in 2017 and ten hotels in 2016 and recorded gains on sales of approximately $279 million, $99 million and $243 million, respectively. In connection with the sale of the Hilton Melbourne South Wharf in 2017, we recorded Australian capital gain tax of $17 million that was paid on the gain on sale. Additionally, on September 21, 2018, we sold the New York Marriott Marquis retail and theater commercial units and the related signage areas of the hotel (the “Retail”) to Vornado Realty Trust for a sale price of $442 million and recorded a gain of approximately $386 million, which is net of the non-cash incurrence of a liability of approximately $35 million related to Vornado’s contractual right to future real estate tax rebates. Substantially all of the net proceeds from the sale of the Retail were used to close out a reverse like-kind exchange structure established in connection with the acquisition of the Hyatt portfolio in March 2018. We elected to pay U.S. and applicable state capital gain tax of approximately $16 million on the capital gain generated by the sale proceeds not used to close out the reverse like-kind exchange rather than distribute the capital gain to our stockholders. A t December 31, 2018, the Westin New York Grand Central was classified as held for sale. Subsequent to year end, we sold the hotel for $302 million, including approximately $20 million of FF&E replacement funds that were retained by us.

Fair Value Measurements	13. Fair Value Measurements Impairment During 2018, we recorded an impairment expense of $8 million related to the W New York, $13 million related to the W New York – Union Square and $23 million related to the Westin New York Grand Central based on the expected sale proceeds of the properties, which is considered an observable input other than quoted prices (Level 2) in the GAAP fair value hierarchy. The W New York and W New York – Union Square hotels were sold during 2018 and the Westin New York Grand Central is classified as held-for-sale as of December 31, 2018. The fair value of the Westin New York Grand Central, less costs to sell, at December 31, 2018 was $270 million. During 2018, we also recorded an impairment expense of $216 million related to the Sheraton New York Times Square Hotel based on a range of sale prices currently being negotiated with a potential buyer, which is considered an observable input other than quoted prices (Level 2) in the GAAP fair value hierarchy. The fair value of the Sheraton New York Times Square Hotel following the impairment was $495 million. In 2017, we recorded an impairment expense of $43 million related to the W New York. The fair value was based on the expected sale proceeds of the property, which is considered an observable input other than quoted prices (Level 2) in the GAAP fair value hierarchy. The property was sold in 2018. Impairment expense for 2018 and 2017 is recorded in depreciation and amortization on the Consolidated Statements of Operations. Other Liabilities Fair Value of Other Financial Liabilities. We did not elect the fair value measurement option for any of our other financial liabilities.

Relationship with Marriott International We have entered into various agreements with Marriott, including those for the management or franchise of approximately 75% of our hotels (as measured by revenues) and certain limited administrative services. In 2018, 2017 and 2016, we paid Marriott $200 million, $199 million and $159 million, respectively, of hotel management fees and approximately $11.7 million, $9.7 million and $4.6 million, respectively, of franchise fees.

Contractors [Abstract]
Hotel Management Agreements and Operating and License Agreements	15. Hotel Management Agreements and Operating and License Agreements All of our hotels are managed by third parties pursuant to management or operating agreements, with some of our hotels also being subject to separate license agreements addressing matters pertaining to operations under the designated brand. Hotels managed or franchised by Marriott and Hyatt represent 75% and 17% of our total revenues, respectively. Under these agreements, the managers generally have sole responsibility for all activities necessary for the day-to-day operation of the hotels, including establishing room rates, processing reservations and promoting and publicizing the hotels. The managers also provide all employees for the hotels, prepare reports, budgets and projections, control the working capital, and provide other administrative and accounting support services to the hotels. We have approval rights over budgets, capital expenditures, significant leases and contractual commitments, and various other matters. The initial term of our agreements generally is 10 to 25 years, with one or more renewal terms at the option of the manager. The majority of our agreements condition the manager’s right to exercise options for renewal upon the satisfaction of specified economic performance criteria. The manager typically receives a base management fee, which is calculated as a percentage (generally 2-3%) of annual gross revenues, and an incentive management fee, which typically is calculated as a percentage (generally 10-20%) of operating profit after the owner has received a priority return on its investment. In the case of our hotels operating under the W ® ® ® ® ® Pursuant to the agreements, the manager furnishes the hotels with certain chain services, which generally are provided on a central or regional basis to all hotels in the manager’s hotel system. Chain services include central training, advertising and promotion, national reservation systems, computerized payroll and accounting services, and such additional services as needed which may be more efficiently performed on a centralized basis. Costs and expenses incurred in providing such services are allocated among the hotels managed, owned or leased by the manager on a fair and equitable basis. In addition, our managers generally sponsor a guest rewards program, the costs of which are charged to all of the hotels that participate in such program. We are obligated to provide the manager with sufficient funds, generally 4-5% of the revenue generated at the hotel, to cover the cost of (a) certain non-routine repairs and maintenance to the hotels which normally are capitalized, and (b) replacements and renewals to the hotels’ furniture, fixtures and equipment. Under certain circumstances, we will be required to establish escrow accounts for such purposes under terms outlined in the agreements. We generally are limited in our ability to sell, lease or otherwise transfer the hotels unless the transferee assumes the related management agreement. However, most agreements include owner rights to terminate the agreements on the basis of the manager’s failure to meet certain performance-based metrics. Typically, these criteria are subject to the manager’s ability to ‘cure’ and avoid termination by payment to us of specified deficiency amounts (or, in some instances, waiver of the right to receive specified future management fees). In addition to any performance-based or other termination rights, we have negotiated with Marriott and some of our other managers specific termination rights related to specific agreements. These termination rights can take a number of different forms, including termination of agreements upon sale that leave the property unencumbered by any agreement; termination upon sale provided that the property continues to be operated under a license or franchise agreement with continued brand affiliation; as well as termination without sale or other condition, which may require the payment of a fee. These termination rights also may restrict the number of agreements that may be terminated over any annual or other period; impose limitations on the number of agreements terminated as measured by EBITDA; require that a certain number of properties continue to maintain the brand affiliation; or be restricted to a specific pool of assets.

Segment Reporting [Abstract]
Geographic and Business Segment Information	16. Geographic and Business Segment Information We consider each one of our hotels to be an operating segment, none of which meets the threshold for a reportable segment. We also allocate resources and assess operating performance based on individual hotels. All of our other real estate investment activities (primarily our retail and office spaces) are immaterial and, with our operating segments, meet the aggregation criteria, and thus, we report one segment: hotel ownership. Our international operations consist of hotels in two countries as of December 31, 2018. There were no intersegment sales during the periods presented. The following table presents revenues and long-lived assets for each of the geographical areas in which we operate (in millions): 2018 2017 2016 Revenues Property and Equipment, net Revenues Property and Equipment, net Revenues Property and Equipment, net United States $ 5,417 $ 9,651 $ 5,260 $ 9,548 $ 5,259 $ 9,913 Australia — — 19 — 34 85 Brazil 19 49 22 59 34 63 Canada 67 60 59 71 54 71 Chile — — — — 9 — Mexico 21 — 27 14 29 13 New Zealand — — — — 11 — Total $ 5,524 $ 9,760 $ 5,387 $ 9,692 $ 5,430 $ 10,145

Commitments And Contingencies Disclosure [Abstract]
Legal Proceedings, Guarantees and Contingencies	17. Legal Proceedings, Guarantees and Contingencies We are involved in various legal proceedings in the ordinary course of business regarding the operation of our hotels and company matters. To the extent not covered by insurance, these lawsuits generally fall into the following broad categories: disputes involving hotel-level contracts, employment litigation, compliance with laws such as the Americans with Disabilities Act, tax disputes and other general matters. Under our management agreements, our operators have broad latitude to resolve individual hotel-level claims for amounts generally less than $150,000. However, for matters exceeding such threshold, our operators may not settle claims without our consent. Based on our analysis of legal proceedings with which we currently are involved or of which we are aware and our experience in resolving similar claims in the past, we have recorded minimal accruals as of December 31, 2018 related to such claims. We have estimated that, in the aggregate, our losses related to these proceedings would not be material. We are not aware of any other matters with a reasonably possible unfavorable outcome for which disclosure of a loss contingency is required. No assurances can be given as to the outcome of any pending legal proceedings. Hurricane Loss Contingency All of our hotels in Houston and Florida were affected by Hurricanes Harvey and Irma in August and September 2017, respectively. All four of our hotels in Houston were able to remain operational during the hurricane. In Florida, due to evacuation mandates and loss of commercial power, seven of our nine properties were closed for a period of time. We still are evaluating the property and business interruption impact to our hotels. However, our current estimate of the book value of the property and equipment written off, and the related repairs and cleanup costs, is approximately $33 million and have recorded a corresponding insurance receivable of $33 million. We believe our insurance coverage should be sufficient to cover a substantial portion of the property damage to the hotels and the near-term loss of business. As of December 31, 2018, we have received $14 million of property insurance proceeds related to these claims, reducing the receivable to $19 million. Additionally, in 2018 and 2017, we received $7 million and $8 million of business interruption proceeds, respectively, related to the disruption from the hurricanes, which is included in gain on insurance and business interruption settlements on our consolidated statements of operations. Guarantees and Contingencies We have entered into certain guarantees which consist of commitments made to third parties for leases or debt that are not recognized in our consolidated financial statements due to various dispositions, spin-offs and contractual arrangements, but that we have agreed to pay in the event of certain circumstances, including the default by an unrelated party. We also may have contingent environmental liabilities related to the presence of hazardous or toxic substances. We consider the likelihood of any material payments under these guarantees and contingencies to be remote.

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include the consolidated accounts of Host Inc., Host L.P. and their subsidiaries and controlled affiliates, including joint ventures and partnerships. We consolidate subsidiaries when we have the ability to control them. For the majority of our hotel and real estate investments, we consider those control rights to be (i) approval or amendment of developments plans, (ii) financing decisions, (iii) approval or amendments of operating budgets, and (iv) investment strategy decisions. We also evaluate our subsidiaries to determine if they are variable interest entities (“VIEs”). If a subsidiary is a VIE, it is subject to the consolidation framework specifically for VIEs. Typically, the entity that has the power to direct the activities that most significantly impact economic performance consolidates the VIE. We consider an entity to be a VIE if equity investors own an interest therein that does not have the characteristics of a controlling financial interest or if such investors do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. We review our subsidiaries and affiliates at least annually to determine if (i) they should be considered VIEs, and (ii) whether we should change our consolidation determination based on changes in the characteristics thereof. Three partnerships are considered VIE’s, as the general partner maintains control over the decisions that most significantly impact the partnerships. The first VIE is the operating partnership, Host L.P., which is consolidated by Host Inc., of which Host Inc. is the general partner and holds 99% of the limited partner interests. Host Inc.’s sole significant asset is its investment in Host L.P. and substantially all of Host Inc.’s assets and liabilities represent assets and liabilities of Host L.P. All of Host Inc.’s debt is an obligation of Host L.P. and may be settled only with assets of Host L.P. The consolidated partnership that owns the Houston Airport Marriott at George Bush Intercontinental, of which we are the general partner and hold 85% of the partnership interests, also is a VIE. The total assets of this VIE at December 31, 2018 are $48 million and consist primarily of cash and property and equipment. Liabilities for the VIE total $4 million and consist of accounts payable and deferred revenue. The unconsolidated partnership that owns the Philadelphia Marriott Downtown, of which we hold 11% of the limited partner interests, also is a VIE. The carrying amount of this investment at December 31, 2018 is $(6) million and is included in advances to and investments in affiliates. The mortgage debt held by this VIE is non-recourse to us.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments with a maturity of three months or less at the date of purchase to be cash equivalents.
Property and Equipment	Property and Equipment Generally, property and equipment is recorded at cost. For properties we develop, cost includes interest and real estate taxes incurred during construction. For property and equipment acquired in a business combination, we record the assets based on their fair value as of the acquisition date. Replacements and improvements and capital leases are capitalized, while repairs and maintenance are expensed as incurred. Properties acquired in an asset acquisition are recorded at cost, allocated using their relative fair values. We capitalize certain inventory (such as china, glass, silver, and linen) at the time of a hotel opening or acquisition, or when significant inventory is purchased (in conjunction with a major rooms renovation or when the number of rooms or meeting space at a hotel is expanded). These amounts then are amortized over the estimated useful life of three years. Subsequent replacement purchases are expensed when placed in service. We maintain a furniture, fixtures and equipment replacement fund for renewal and replacement capital expenditures at our hotels, which generally is funded with 5% of property revenues. Impairment testing. We analyze our consolidated properties for impairment throughout the year when events or circumstances occur that indicate the carrying value may not be recoverable. We test for impairment in several situations, including: • when a property has a current or projected loss from operations; • when it becomes more likely than not that a hotel will be sold before the end of its previously estimated useful life and the anticipated sales price is at or below the book value; or • when other events, trends, contingencies or changes in circumstances indicate that a triggering event has occurred and the carrying value of an asset may not be recoverable . To the extent that a property has a substantial remaining estimated useful life and management does not believe that it is more likely than not that the property will be sold prior to the end thereof, it would be unusual for undiscounted cash flows to be insufficient to recover the property’s carrying value. In the absence of other factors, we assume that the estimated useful life is equal to the remaining GAAP depreciable life because of the continuous property maintenance and improvement capital expenditures required under our management agreements. We adjust our assumptions with respect to the remaining useful life of the property if situations dictate otherwise, such as an expiring ground lease, or that it is more likely than not that the asset will be sold prior to the end of its previously expected useful life. We also consider the effect of regular renewal and replacement capital expenditures on the estimated useful life of our properties, including critical infrastructure, which regularly is maintained and then replaced at the end of its useful life. During 2018, due to a reduction in the estimated hold period of the assets, we impaired four assets, totaling $260 million. No other properties had triggering events warranting impairment testing. During 2017, we recognized impairment expense of $43 million on one property. Impairment expense is included in depreciation and amortization expense. No impairment was recorded in 2016. See Note 13. Fair Value Measurements. Classification of Assets as “Held for Sale”. We will classify a hotel as held for sale when its sale is probable, will be completed within one year and actions to complete the sale are unlikely to change or that the sale will not occur. This policy is consistent with our experience with real estate transactions under which the timing and final terms of a sale frequently are not known until purchase agreements are executed, the buyer has a significant deposit at risk and no financing contingencies exist which could prevent the transaction from being completed in a timely manner. We typically classify assets as held for sale when all the following conditions are met: • Host Inc.’s Board of Directors has approved the sale (to the extent that the dollar amount of the sale requires Board approval); • a binding agreement to sell the property has been signed under which the buyer has committed a significant amount of nonrefundable cash; and • no significant financing contingencies exist which could prevent the transaction from being completed in a timely manner. If these criteria are met, we will cease recording depreciation expense and will record an impairment expense if the fair value less costs to sell is less than the carrying amount of the hotel. We will classify the assets and related liabilities as held for sale on the balance sheet. Gains on sales of properties are recognized at the time of sale or are deferred and recognized as income in subsequent periods as conditions requiring deferral are satisfied or expire without further cost to us. Discontinued Operations. We generally include the operations of a hotel that was sold or a hotel that has been classified as held for sale in continuing operations, including the gain or loss on the sale, unless the sale represents a strategic shift that will have a major impact on our future operations and financial results. Asset retirement obligations. We recognize the fair value of any liability for conditional asset retirement obligations, including environmental remediation liabilities, when incurred, which generally is upon acquisition, construction, or development and/or through the normal operation of the asset, if information exists with which to reasonably estimate the fair value of the obligation. Depreciation and Amortization Expense. We depreciate our property and equipment using the straight-line method. Depreciation expense is based on the estimated useful life of our assets and amortization expense for leasehold improvements is based on the shorter of the lease term or the estimated useful life of the related assets. The useful lives of the assets are based on several assumptions, including cost and timing of capital expenditures to maintain and refurbish the assets, as well as specific market and economic conditions. While management believes its estimates are reasonable, a change in the estimated useful lives could affect depreciation expense and net income (loss) or the gain or loss on the sale of any of our hotels.
Intangible Assets and Acquired Liabilities	Intangible Assets and Acquired Liabilities In conjunction with our acquisitions, we may identify intangible assets and other liabilities. These identifiable intangible assets and other liabilities typically include above and below market contracts, including ground and retail leases and management and franchise agreements, which are recorded at fair value in a business combination and at its relative fair value in an asset acquisition. These contract values are based on the present value of the difference between contractual amounts to be paid pursuant to the contracts acquired and our estimate of the fair value of rates for similar contracts measured over the period equal to the remaining non-cancelable term of the contract. Intangible assets and other liabilities are amortized using the straight-line method over the remaining non-cancelable term of the related agreements.
Non-Controlling Interests	Non-Controlling Interests Other Consolidated Partnerships. As of December 31, 2018, we consolidate three majority-owned partnerships that have third-party, non-controlling ownership interests. The third-party partnership interests are included in non-redeemable non-controlling interest-other consolidated partnerships on the consolidated balance sheets and totaled $72 million and $29 million as of December 31, 2018 and 2017, respectively. Approximately $66 million of the balance at December 31, 2018 relates to the partnership that owned the JW Marriott Hotel Mexico City that was sold in 2018, representing the portion of proceeds owed to the third-party interest that was paid in January 2019. Net income attributable to non-controlling interests of consolidated partnerships is included in our determination of net income. Net income attributable to non-controlling interests of third parties was $52 million for the year ended December 31, 2018, and immaterial for each of the years ended December 31, 2017 and 2016. Host Inc.’s treatment of the non-controlling interests of Host L.P. Host Inc. adjusts the non-controlling interests of Host L.P. each period so that the amount presented equals the greater of its carrying value based on its historical cost or its redemption value. The historical cost is based on the proportional relationship between the historical cost of equity held by our common stockholders relative to that of the unitholders of Host L.P. The redemption value is based on the amount of cash or Host Inc. common stock, at our option, that would be paid to the non-controlling interests of Host L.P. if it were terminated. We have estimated that the redemption value is equivalent to the number of shares issuable upon conversion of the OP units currently owned by unaffiliated limited partners (one OP unit may be exchanged for 1.021494 shares of Host Inc. common stock) valued at the market price of Host Inc. common stock at the balance sheet date. Redeemable non-controlling interests of Host L.P. are classified in the mezzanine section of the balance sheet as they do not meet the requirements for equity classification because the redemption feature requires the delivery of registered shares. The table below details the historical cost and redemption values for the non-controlling interests of Host L.P.: As of December 31, 2018 2017 OP units outstanding (millions) 7.5 8.2 Market price per Host Inc. common share $ 16.67 $ 19.85 Shares issuable upon conversion of one OP unit 1.021494 1.021494 Redemption value (millions) $ 128 $ 167 Historical cost (millions) 78 80 Book value (millions) (1) 128 167 ___________ (1) Net income is allocated to the non-controlling interests of Host L.P. based on their weighted average ownership percentage during the period. Net income attributable to Host Inc. has been reduced by the amount attributable to non-controlling interests in Host L.P., which totaled $12 million, $7 million, and $9 million for 2018, 2017, and 2016, respectively.
Investments in Affiliates	Investments in Affiliates Other-than-Temporary Impairment of an Investment. We perform an analysis on each of our equity method investments for impairment based on the occurrence of triggering events that would indicate that the carrying amount of an investment exceeds its fair value on an other-than-temporary basis. Triggering events can include a decline in distributable cash flows from the investment, a change in the expected useful life or other significant events which would decrease the value of the investment. Our investments primarily consist of joint ventures which own hotels; therefore, generally we will have few observable inputs and will determine fair value based on a discounted cash flow analysis of the investment, as well as consideration of the impact of other elements (i.e. control premiums, etc.). We use certain inputs, such as available third-party appraisals and forecast net operating income for the hotels, to estimate the expected cash flows. If an equity method investment is impaired and that impairment is determined to be other than temporary, an expense is recorded for the difference between the fair value and the carrying amount of the investment. No other-than-temporary impairment expense was recorded in 2018, 2017 and 2016. Distributions from Investments in Affiliates. We classify the distributions from our equity investments in the statements of cash flows based upon an evaluation of the specific facts and circumstances of each distribution. For example, distributions from cash generated by property operations are classified as cash flows from operating activities. However, distributions received because of property sales are classified as cash flows from investing activities.
Income Taxes	Income Taxes Host Inc. elected to be treated as a REIT effective January 1, 1999, pursuant to the U.S. Internal Revenue Code of 1986, as amended. It is our intention to continue to comply with the REIT qualification requirements and to maintain our qualification for taxation as a REIT. A corporation that elects REIT status and meets certain tax law requirements regarding the distribution of its taxable income to its stockholders as prescribed by applicable tax laws and complies with certain other requirements (relating primarily to the composition of its assets and the sources of its gross income) generally is not subject to federal and state income taxation on its operating income that is distributed to its stockholders. As a partnership for federal income tax purposes, Host L.P. is not subject to federal income tax. Host L.P. is, however, subject to state, local and foreign income and franchise tax in certain jurisdictions. Additionally, each of the Host L.P. taxable REIT subsidiaries is taxable as a regular C corporation, subject to federal, state and foreign income tax. Our consolidated income tax provision includes the income tax provision related to the operations of our taxable REIT subsidiaries, federal and state corporate income taxes on certain items of capital gain generated by Host L.P., and state, local, and foreign income and franchise taxes incurred by Host L.P. and its subsidiaries. Deferred Pursuant to its partnership agreement, Host L.P. generally is required to reimburse Host Inc. for any tax payments it is required to make. Accordingly, the tax information included herein represents disclosures regarding Host Inc. and its subsidiaries. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for net operating loss and capital loss carryovers. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which such amounts are expected to be realized or settled. The effect on deferred tax assets and liabilities from a change in tax rates is recognized in earnings in the period when the new rate is enacted. However, deferred tax assets are recognized only to the extent that it is more likely than not that they will be realized based on consideration of available evidence, including future reversals of existing taxable temporary differences, future projected taxable income and tax planning strategies. GAAP prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return. We must 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. Once it is determined that a position meets the more-likely-than-not recognition threshold, the position is measured at the largest amount of benefit that is greater than 50% likely of being realized upon settlement to determine the amount of benefit to recognize in the financial statements. This accounting standard applies to all tax positions related to income taxes. We recognize any accrued interest related to unrecognized tax benefits in interest expense and penalties in operating expenses.
Deferred Charges	Deferred Charges Financing costs related to long-term debt are deferred and amortized over the remaining life of the debt using the effective interest method. These costs are presented as a direct deduction from the related long-term debt on the balance sheets.
Foreign Currency Translation	Foreign Currency Translation As of December 31, 2018, our international operations consist of hotels located in Brazil and Canada, as well as an investment in an Asia/Pacific joint venture. The financial statements of these hotels and our investments therein are maintained in their functional currency, which generally is the local currency, and their operations are translated to U.S. dollars using the average exchange rates for the period. The assets and liabilities of the hotels and the investments therein are translated to U.S. dollars using the exchange rate in effect at the balance sheet date. The resulting translation adjustments are reflected in other comprehensive income (loss). Foreign currency transactions are recorded in the functional currency for each applicable foreign entity using the exchange rates prevailing at the dates of the transactions. Assets and liabilities denominated in foreign currencies are remeasured at period end exchange rates. The resulting exchange differences are recorded in gain (loss) on foreign currency transactions and derivatives on the accompanying consolidated statements of operations, except when recorded in other comprehensive income (loss) as qualifying net investment hedges.
Accumulated Other Comprehensive Income (Loss)	Accumulated Other Comprehensive Income (Loss) The components of total accumulated other comprehensive income (loss) in the balance sheets are as follows (in millions): As of December 31, 2018 2017 Gain on foreign currency forward contracts $ 4 $ 26 Loss on interest rate swap cash flow hedges (4 ) (5 ) Foreign currency translation (60 ) (83 ) Other comprehensive loss attributable to non-controlling interests 1 2 Total accumulated other comprehensive loss $ (59 ) $ (60 ) During ,
Revenues	Revenues Substantially all of our operating results represent revenues and expenses generated by property-level operations. Payments are due from customers when services are provided to them. Due to the short-term nature of our contracts and the almost concurrent receipt of payment, we have no material unearned revenue at year end. We collect sales, use, occupancy and similar taxes at our hotels, which we present on a net basis (excluded from revenues) on our statements of operations. Revenues are recognized, as follows: Income statement line item Recognition method Rooms revenues Rooms revenues represent revenues from the occupancy of our hotel rooms and are driven by the occupancy and average daily rate charged. Rooms revenues do not include ancillary services or fees charged. The contracts for room stays with customers generally are very short term in duration and revenues are recognized over the course of the hotel stay. Food and beverage revenues Food and beverage revenues consist of revenues from group functions, which may include banquet revenues and audio-visual revenues, as well as outlet revenues from the restaurants and lounges at our properties. Revenues are recognized as the services or products are provided. Our hotels may employ third parties to provide certain services at the property, for example, audio and visual services. We evaluate each of these contracts to determine if the hotel is the principal or the agent in the transaction and record the revenues as appropriate (i.e. gross vs. net). Other revenues Other revenues consist of ancillary revenues at the property, including attrition and cancelation fees, golf courses, resort and destination fees, spas, entertainment and other guest services, as well as rental revenues; primarily consisting of leased retail outlets. Other revenues generally are recognized as the services or products are provided. Attrition and cancelation fees are recognized for non-cancelable deposits when the customer provides notification of cancelation or is a no-show for the specified date, whichever comes first.
Fair Value Measurement	Fair Value In evaluating the fair value of both financial and non-financial assets and liabilities, GAAP outlines a valuation framework and creates a fair value hierarchy that distinguishes between market assumptions based on market data (“observable inputs”) and a reporting entity’s own assumptions about market data (“unobservable inputs”). Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability at the measurement date in an orderly transaction (an “exit price”). Assets and liabilities are measured using inputs from three levels of the fair value hierarchy. The three levels are as follows: Level 1 — Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date. An active market is defined as a market in which transactions occur with sufficient frequency and volume to provide pricing on an ongoing basis. Level 2 — Inputs include quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active (markets with few transactions), inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data correlation or other means. Level 3 — Unobservable inputs reflect our assumptions about the pricing of an asset or liability when observable inputs are not available.
Earnings Per Common Share (Unit)	Earnings Per Common Share (Unit) Basic earnings per common share (unit) is computed by dividing net income attributable to common stockholders (unitholders) by the weighted average number of shares of Host Inc. common stock or Host L.P. common units outstanding. Diluted earnings per common share (unit) is computed by dividing net income attributable to common stockholders (unitholders), as adjusted for potentially dilutive securities, by the weighted average number of shares of Host Inc. common stock or Host L.P. common units outstanding plus other potentially dilutive securities. Dilutive securities may include shares granted under comprehensive stock plans or the common OP units distributed to Host Inc. to support such shares granted, and other non-controlling interests that have the option to convert their limited partner interests to common OP units and convertible debt securities. No effect is shown for any securities that are anti-dilutive. The calculation of Host Inc. basic and diluted earnings per common share is shown below (in millions, except per share amounts): Year ended December 31, 2018 2017 2016 Net income $ 1,151 $ 571 $ 771 Less: Net income attributable to non-controlling interests (64 ) (7 ) (9 ) Net income attributable to Host Inc. $ 1,087 $ 564 $ 762 Basic weighted average shares outstanding 739.8 738.6 743.0 Assuming distribution of common shares granted under the comprehensive stock plans, less shares assumed purchased at market 0.8 0.5 0.7 Diluted weighted average shares outstanding 740.6 739.1 743.7 Basic earnings per common share $ 1.47 $ .76 $ 1.03 Diluted earnings per common share $ 1.47 $ .76 $ 1.02 The calculation of Host L.P. basic and diluted earnings per common unit is shown below (in millions, except per unit amounts): Year ended December 31, 2018 2017 2016 Net income $ 1,151 $ 571 $ 771 Less: Net income attributable to non-controlling interests (52 ) — — Net income attributable to Host L.P. $ 1,099 $ 571 $ 771 Basic weighted average units outstanding 732.2 731.5 736.3 Assuming distribution of common units to support shares granted under the comprehensive stock plans, less shares assumed purchased at market 0.8 0.5 0.6 Diluted weighted average units outstanding 733.0 732.0 736.9 Basic earnings per common unit $ 1.50 $ .78 $ 1.05 Diluted earnings per common unit $ 1.50 $ .78 $ 1.05
Share-Based Payments	Share-Based Payments At December 31, 2018, Host Inc. maintained two stock-based employee compensation plans. Upon the issuance of Host’s common stock under the compensation plans, Host L.P. will issue to Host Inc. common OP units of an equivalent value. These liabilities are included in the consolidated financial statements for Host Inc. and Host L.P. We recognize costs resulting from Host Inc.’s share-based payment transactions over their vesting periods. We classify share-based payment awards granted in exchange for employee services either as equity-classified awards or liability-classified awards. Equity-classified awards are measured based on the fair value on the date of grant. Liability-classified awards are remeasured to fair value each reporting period. Effective January 1, 2017, we implemented a new stock-based employee compensation plan. In conjunction with the adoption of ASU No. 2016-09, the awards under the new plan are classified as equity. The plan includes awards that vest over a one-year, two-year and three-year period. For performance-based awards, compensation cost will be recognized when the achievement of the performance condition is considered probable. If a performance condition has more than one outcome that is probable, recognition of compensation cost will be based on the condition that is the most likely outcome. No compensation cost is recognized for awards for which employees do not render the requisite services.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents. We are exposed to credit risk with respect to cash held at various financial institutions and access to our credit facility, however, this cash balance is spread among a diversified group of investment grade financial institutions.
Acquisitions and Business Combinations	Acquisitions and When acquiring an asset, we determine whether the acquisition is an asset acquisition or business combination based on whether the fair value of the gross assets acquired is concentrated in a single (group of similar) identifiable assets, resulting in an asset acquisition or not, resulting in a business combination. If an asset acquisition, the asset is recorded in accordance with our property and equipment policy and related acquisition costs are capitalized as part of the asset. In a business combination, we recognize identifiable assets acquired, liabilities assumed, and non-controlling interests at their fair values at the acquisition date based on the exit price (i.e. the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date). We evaluate several factors, including market data for similar assets, expected cash flows discounted at risk adjusted rates and replacement cost for the assets to determine an appropriate exit cost when evaluating the fair value of our assets and liabilities acquired. Property and equipment are recorded at fair value and such fair value is allocated to buildings, improvements, furniture, fixtures and equipment using appraisals and valuations performed by management and independent third parties. Acquisition-related costs, such as due diligence, legal and accounting fees, are not capitalized or applied in determining the fair value of the acquired assets. Other items that we evaluate in a business combination include identifiable intangible assets, capital lease assets and obligations and goodwill. Identifiable intangible assets typically consist of assumed contracts, including ground and retail leases and management and franchise agreements, which are recorded at fair value. Capital lease obligations that are assumed as part of the acquisition of a leasehold interest are measured at fair value and are included as debt on the accompanying balance sheet and we record the corresponding right-to-use assets. Classification of a lease does not change if it is part of a business combination. In making estimates of fair values for purposes of allocating purchase price, we may utilize a number of sources that arise in connection with the acquisition or financing of a property and other market data, including third-party appraisals and valuations. In certain situations, and usually only in connection with the acquisition of a foreign hotel, a deferred tax liability is recognized due to the difference between the fair value and the tax basis of the acquired assets at the acquisition date. Any consideration paid in excess of the net fair value of the identifiable assets and liabilities acquired would be recorded to goodwill. In very limited circumstances, we may record a bargain purchase gain if the consideration paid is less than the net fair value of the assets and liabilities acquired.
Reclassifications	Reclassifications Certain prior year financial statement amounts have been reclassified to conform with the current year presentation.
New Accounting Standards	New Accounting Standards Leases. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which affects aspects of accounting for lease agreements. Under the new standard, all leases, including operating leases, will require recognition of the lease assets and lease liabilities by lessees on the balance sheet. However, the effect on the statement of operations and the statement of cash flows largely is unchanged. The standard is effective for fiscal years beginning after December 15, 2018. The standard requires adoption using a modified retrospective approach, with the option of restatement of the comparative periods presented in the year of adoption or applying the new standard only in the year of adoption with a cumulative-effect adjustment in the period of adoption. The primary impact of the new standard on us will be to the treatment of our 25 ground leases, which represent approximately 85% of our annual operating lease payments. We believe that application of this standard will result in us recording a right of use asset and the related lease liability of between $500 million and $600 million for the ground leases, although changes in discount rates, ground lease terms or other variables may have a significant effect on the calculation of this recorded amount. As noted above, we expect that the adoption of this standard will have minimal impact on our income statement, including our revenues Business Combinations. We adopted ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business on January 1, 2018. The standard adopts a two-step approach wherein, if substantially all of the fair value of the gross assets acquired is concentrated in a single (group of similar) identifiable asset(s), then the transaction will be considered an asset purchase. We anticipate that most of our future hotel purchases will be considered asset purchases as opposed to business combinations, although this determination will be made on a transaction-by-transaction basis. This standard was adopted on a prospective basis and, therefore, it did not affect the accounting for any of our previous acquisitions. Revenue Recognition. We adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), on January 1, 2018 . The standard sets forth steps to determine the timing and amount of revenue to be recognized to depict the transfer of goods or services in an amount that reflects the consideration that an entity expects in exchange. We also adopted ASU No. 2017-05, Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) , which provides further guidance on accounting for the derecognition and partial sales of a non-financial asset. This standard may allow for earlier gain recognition for certain sale transactions pursuant to which we have continuing involvement with the asset that was sold. We adopted these standards using a modified retrospective approach with a cumulative effect recognized in our equity balance on the date of adoption and no restatements of prior period amounts. When applying the new standard for the cumulative effect, we elected to apply the new standard only to contracts that were not considered completed as of the date of adoption. Transition adjustment. As a result of the adoption of this standard on January 1, 2018, total liabilities were reduced by $4.5 million, and total equity of Host Inc. stockholders and total Host L.P. partner capital increased by $4.5 million. This adjustment is related to a previously deferred gain on the sale of the Atlanta Marriott Marquis in 2013 that would have qualified for recognition under the new standard. Our balance sheet as of December 31, 2018 includes $0.4 million retained as a contingent liability for potential environmental liabilities at the Atlanta Marriott Marquis; however, our potential exposure related to the guarantee can be up to $5 million. Adoption did not have an effect on our income statement for 2018. Policy Disclosure. There has been no significant change to our method of revenue recognition for our primary operations; however, we have updated our accounting policy and disclosures for the revenue recognition standard. See above for this policy and Note 2. Revenues for a disaggregation of revenues.
