	2	Summary of Significant Accounting Policies
	We have condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with GAAP in the accompanying unaudited condensed consolidated financial statements. We believe the disclosures made herein are adequate to prevent the information presented from being misleading. However, the financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10–K for the year ended December 31, 2013.
	The preparation of financial statements in conformity with 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.
	In our opinion, the accompanying financial statements reflect all adjustments necessary to present fairly our financial position as of September 30, 2014, and the results of our operations for the quarter and year-to-date periods ended September 30, 2014 and 2013, respectively, and cash flows for the year-to-date periods ended September 30, 2014 and 2013, respectively. Interim results are not necessarily indicative of full year performance because of the impact of seasonal variations.
	Reclassifications
	Certain prior year financial statement amounts have been reclassified to conform with the current year presentation.
	New Accounting Standards
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which affects virtually all aspects of an entity’s revenue recognition.  The core principle of the new standard is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  The standard is effective for annual reporting periods beginning after December 15, 2016.  We have not yet completed our assessment of the effect of the new standard on our financial statements, including possible transition alternatives.
	In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360) - Reporting Discontinued Operations and Disclosure of Disposal of Components of an Entity (“ASU 2014-08 Reporting for Discontinued Operations”). Under this standard, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations only if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results.  In addition, it requires an entity to present, for each comparative period, the assets and liabilities of a disposal group that includes a discontinued operation separately in the asset and liability sections, respectively, of the statement of financial position. As a result, the operations of sold properties through the date of their disposal will be included in continuing operations, unless the sale represents a strategic shift. We adopted this standard as of January 1, 2014. No prior year restatements are permitted for this change in policy.

	Host Inc. Earnings Per Common Share
	Basic earnings per common share is computed by dividing net income attributable to common stockholders by the weighted average number of shares of Host Inc. common stock outstanding. Diluted earnings per common share is computed by dividing net income attributable to common stockholders, as adjusted for potentially dilutive securities, by the weighted average number of shares of Host Inc. common stock outstanding plus other potentially dilutive securities. Dilutive securities may include shares granted under comprehensive stock plans, other non-controlling interests that have the option to convert their limited partnership interests to common OP units and convertible debt securities. No effect is shown for any securities that are anti-dilutive. The calculation of basic and diluted earnings per common share is shown below (in millions, except per share amounts):

Net income allocated to non-controlling interests of Host L.P. has been excluded from the numerator and common OP units in Host L.P. have been omitted from the denominator for the purpose of computing diluted earnings per share since the effect of including these amounts would have no impact.
	Host L.P. Earnings Per Common Unit
	Basic earnings per common unit is computed by dividing net income attributable to common unitholders by the weighted average number of common units outstanding. Diluted earnings per common unit is computed by dividing net income attributable to common unitholders, as adjusted for potentially dilutive securities, by the weighted average number of common units outstanding plus other potentially dilutive securities. Dilutive securities may include units issued to Host Inc. to support Host Inc. common shares granted under comprehensive stock plans, other non-controlling interests that have the option to convert their limited partnership interests to common OP units and convertible debt securities. No effect is shown for any securities that are anti-dilutive. The calculation of basic and diluted earnings per unit is shown below (in millions, except per unit amounts):

	On September 30, 2014, the Euro JV Fund II acquired a 90% ownership interest in the 394-room Grand Hotel Esplanade in Berlin. The hotel was acquired based on an aggregate gross value of €81 million ($102 million), and is subject to approximately €48 million ($61 million) of debt with a margin of 219 basis points over the Euro Interbank Offered Rate (“Euribor”), which is non-recourse to the Euro JV. We contributed approximately €10 million ($14 million) to the Euro JV in connection with this acquisition, partially funded through a draw on our credit facility.
	Subsequent to quarter end, on October 16, 2014, the Euro JV Fund I sold the 350-room Sheraton Skyline Hotel & Conference Centre for £33 million ($53 million).

As a result, operations and any gain or loss on sale of hotels sold subsequent to December 31, 2013 will continue to be reported in continuing operations. The results of properties sold in 2013, including the gain on sale, prior to adoption will continue to be reported in discontinued operations.
	On October 1, 2014, we sold the Tampa Marriott Waterside Hotel & Marina for approximately $199 million, which includes a $9 million FF&E replacement fund retained at the hotel. The hotel is classified as held for sale as of September 30, 2014. We will record a gain on sale of approximately $115 million in the fourth quarter. Additionally, during the first quarter of 2014, we sold an 89% controlling interest in the Philadelphia Marriott Downtown based on a gross sales price of $303 million and sold the Courtyard Nashua for approximately $10 million.

On January 21, 2014, we acquired the 151-room Powell Hotel in San Francisco, California, including retail space, for approximately $75 million. Accounting for acquisitions requires an allocation of the purchase price to the assets acquired and the liabilities assumed at their respective estimated fair values. The purchase price allocation for the b2 miami downtown hotel is estimated based on currently available information; however, we still are in the process of obtaining appraisals and finalizing the accounting for this acquisition.

	Derivatives and Hedging
	Interest rate swap derivatives designated as cash flow hedges. We have designated our floating-to-fixed interest rate swap derivatives as cash flow hedges. The purpose of the interest rate swaps is to hedge against changes in cash flows (interest payments) attributable to fluctuations in variable rate debt. The derivatives are valued based on the prevailing market yield curve on the date of measurement. We also evaluate counterparty credit risk when we calculate the fair value of the swaps. Changes in the fair value of the derivatives are recorded to other comprehensive income (loss). The hedges were fully effective as of September 30, 2014.
	The following table summarizes our interest rate swap derivatives designated as cash flow hedges (in millions):

	-2	The swap was entered into in connection with the NZ$105 million ($82 million) mortgage loan on seven properties in New Zealand.
	Foreign Investment Hedging Instruments. We have four foreign currency forward sale contracts that hedge a portion of the foreign currency exposure resulting from the eventual repatriation of our net investment in foreign operations. These derivatives are considered hedges of the foreign currency exposure of a net investment in a foreign operation and are marked-to-market with changes in fair value recorded to other comprehensive income (loss). The forward sale contracts are valued based on the forward yield curve of the foreign currency to U.S. dollar forward exchange rate on the date of measurement. We also evaluate counterparty credit risk when we calculate the fair value of the derivatives.
	The following table summarizes our foreign currency sale contracts (in millions):

	Other Liabilities
	Fair Value of Other Financial Liabilities. We did not elect the fair value measurement option for any of our other financial liabilities. Valuations for secured debt and our credit facility are determined based on the expected future payments discounted at risk-adjusted rates. Senior Notes and the Exchangeable Senior Debentures are valued based on quoted market prices. The fair values of financial instruments not included in this table are estimated to be equal to their carrying amounts.
	The fair value of certain financial liabilities is shown below (in millions):

Impairment
During the third quarter, an impairment loss of $6 million was triggered for one property due to a change in its expected hold period.  The fair value of the property of $18 million is based on the expected cash flows over the remaining life of the property. The loss is included in depreciation expense.

	We consider each 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 office buildings and apartments) are immaterial and, with our operating segments, meet the aggregation criteria, and thus, we report one segment: hotel ownership. Our consolidated foreign operations consist of hotels in six countries. There were no intersegment sales during the periods presented.

	Other Consolidated Partnerships. We consolidate six majority-owned partnerships that have third-party, non-controlling ownership interests. The third-party partnership interests are included in non-controlling interests — other consolidated partnerships on the condensed consolidated balance sheets and totaled $35 million and $34 million as of September 30, 2014 and December 31, 2013, respectively. Two of the partnerships have finite lives that terminate between 2081 and 2095, and the associated non-controlling interests are mandatorily redeemable at our option at the end of, but not prior to, the finite life. At September 30, 2014 and December 31, 2013, the fair values of the non-controlling interests in the partnerships with finite lives were approximately $70 million and $68 million, respectively.
	Net income attributable to non-controlling interests of consolidated partnerships is included in our determination of net income. Net loss attributable to non-controlling interests of third parties, which is included in the determination of net income (loss) attributable to Host Inc. and Host L.P., was $(1) million for both the quarters ended September 30, 2014 and 2013, respectively. Net income attributable to non-controlling interests of third parties was $4 million and $2 million for the year-to-date periods ended September 30, 2014 and 2013, respectively.
	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 accumulated 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. Therefore, the redemption value of the common OP units is equivalent to the number of shares that would be issued upon conversion of the common OP units held by third parties valued at the market price of Host Inc. common stock at the balance sheet date. One common OP unit may be exchanged into 1.021494 shares of Host Inc. common stock. Non-controlling interests of Host L.P. are classified in the mezzanine section of our balance sheets 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:
			September 30,		December 31,
			2014		2013
	OP units outstanding (millions)			9.4		9.5
	Market price per Host Inc. common share		$	21.33	$	19.44

	Historical cost (millions)			94		95
	Book value (millions) (1)			204		190
	-1	The book value recorded is equal to the greater of redemption value or historical cost.
	Net income is allocated to the non-controlling interests of Host L.P. based on their weighted average ownership interest during the period. The net income attributable to the non-controlling interests of Host L.P. for the quarter and year-to-date ended September 30, 2014 was $2 million and $7 million, respectively. The income attributable to the non-controlling interests of Host L.P. was immaterial for the quarter ended September 30, 2013 and $3 million for the year-to-date ended September 30, 2013.

Commitments And Contingencies Disclosure [Abstract]	'
Legal Proceedings	'
	12	Legal Proceedings
	We are involved in various legal proceedings in the normal course of business regarding the operation of our hotels and company matters. To the extent not covered by insurance, these legal proceedings 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 accrued approximately $31 million as of September 30, 2014 for liabilities related to legal proceedings and estimate that, in the aggregate, our losses related to these proceedings could be as much as $50 million. We believe this range represents the maximum potential loss for all of our legal proceedings. 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.
	On October 3, 2014, the final motion for rehearing by Keystone-Texas Property Holding Corporation (“Keystone”) to the Texas Supreme Court was denied, finalizing the court’s decision. As a result, we have reversed the $69 million loss contingency previously recorded related to this litigation in the third quarter of 2014, which is included in corporate and other expenses. In addition, a court-ordered bond of $25 million was released October 17, 2014, which is included in restricted cash as of September 30, 2014. For further details on this legal proceeding, see Part II, Item 1, Legal Proceedings.

New Accounting Standards	'
	New Accounting Standards
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which affects virtually all aspects of an entity’s revenue recognition.  The core principle of the new standard is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  The standard is effective for annual reporting periods beginning after December 15, 2016.  We have not yet completed our assessment of the effect of the new standard on our financial statements, including possible transition alternatives.
	In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360) - Reporting Discontinued Operations and Disclosure of Disposal of Components of an Entity (“ASU 2014-08 Reporting for Discontinued Operations”). Under this standard, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations only if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results.  In addition, it requires an entity to present, for each comparative period, the assets and liabilities of a disposal group that includes a discontinued operation separately in the asset and liability sections, respectively, of the statement of financial position. As a result, the operations of sold properties through the date of their disposal will be included in continuing operations, unless the sale represents a strategic shift. We adopted this standard as of January 1, 2014. No prior year restatements are permitted for this change in policy.

Earnings Per Common Share (Unit)	'
	Basic earnings per common share is computed by dividing net income attributable to common stockholders by the weighted average number of shares of Host Inc. common stock outstanding. Diluted earnings per common share is computed by dividing net income attributable to common stockholders, as adjusted for potentially dilutive securities, by the weighted average number of shares of Host Inc. common stock outstanding plus other potentially dilutive securities. Dilutive securities may include shares granted under comprehensive stock plans, other non-controlling interests that have the option to convert their limited partnership interests to common OP units and convertible debt securities. No effect is shown for any securities that are anti-dilutive. The calculation of basic and diluted earnings per common share is shown below (in millions, except per share amounts):

Net income allocated to non-controlling interests of Host L.P. has been excluded from the numerator and common OP units in Host L.P. have been omitted from the denominator for the purpose of computing diluted earnings per share since the effect of including these amounts would have no impact.

Earnings Per Common Share (Unit)	'
	Basic earnings per common unit is computed by dividing net income attributable to common unitholders by the weighted average number of common units outstanding. Diluted earnings per common unit is computed by dividing net income attributable to common unitholders, as adjusted for potentially dilutive securities, by the weighted average number of common units outstanding plus other potentially dilutive securities. Dilutive securities may include units issued to Host Inc. to support Host Inc. common shares granted under comprehensive stock plans, other non-controlling interests that have the option to convert their limited partnership interests to common OP units and convertible debt securities. No effect is shown for any securities that are anti-dilutive. The calculation of basic and diluted earnings per unit is shown below (in millions, except per unit amounts):

	On August 11, 2014, we acquired the 242-room b2 miami downtown hotel for approximately $58 million. On January 21, 2014, we acquired the 151-room Powell Hotel in San Francisco, California, including retail space, for approximately $75 million. Accounting for acquisitions requires an allocation of the purchase price to the assets acquired and the liabilities assumed at their respective estimated fair values. The purchase price allocation for the b2 miami downtown hotel is estimated based on currently available information; however, we still are in the process of obtaining appraisals and finalizing the accounting for this acquisition. The following table summarizes the estimated fair value of the assets acquired and liabilities assumed related to these acquisitions (in millions):
