	1.	Organization
	Description of Business
	Host Hotels & Resorts, Inc. operates as a self-managed and self-administered real estate investment trust (“REIT”), with its operations conducted solely through Host Hotels & Resorts, L.P. and its subsidiaries. Host Hotels & Resorts, L.P., a Delaware limited partnership, operates through an umbrella partnership structure, with Host Hotels & Resorts, Inc., a Maryland corporation, as its sole general partner. In the notes to the condensed consolidated financial statements, we use the terms “we” or “our” to refer to Host Hotels & Resorts, Inc. and Host Hotels & Resorts, L.P. together, unless the context indicates otherwise. We also use the term “Host Inc.” specifically to refer to Host Hotels & Resorts, Inc. and the term “Host L.P.” specifically to refer to Host Hotels & Resorts, L.P. in cases where it is important to distinguish between Host Inc. and Host L.P. As of September 30, 2013, Host Inc. holds approximately 98.7% of Host L.P.’s OP units.
	Consolidated Portfolio
	As of September 30, 2013, our consolidated portfolio, primarily consisting of luxury and upper upscale hotels, is detailed below:
		Hotels
	United States	103
	Australia	1
	Brazil	1
	Canada	3
	Chile	2
	Mexico	1
	New Zealand	7
	Total	118
	Joint Ventures
	We own a non-controlling interest in a joint venture in Europe (“Euro JV”) that owns hotels in two separate funds. We own a 32.1% interest in the first fund (“Euro JV Fund I”) (11 hotels) and a 33.4% interest in the second fund (“Euro JV Fund II”) (9 hotels).
	As of September 30, 2013, the Euro JV owned hotels located in the following countries:
		Hotels
	Belgium	3
	France	5
	Germany	1
	Italy	3
	Poland	1
	Spain	2
	Sweden	1
	The Netherlands	2
	United Kingdom	2
	Total	20
	In addition, our joint venture in Asia (“Asia/Pacific JV”), in which we own a 25% non-controlling interest, owns one hotel in Australia and a non-controlling interest in an entity with two hotels in India.
	Change in Reporting Periods
	Effective January 1, 2013, we report quarterly operating results on a calendar cycle, which now is consistent across all of our hotel managers and the majority of companies in the lodging industry. Historically, our annual financial statements have been reported on a calendar basis and are unaffected by this change. However, our quarterly operating results had been reported based on a 52-53 week fiscal calendar used by Marriott International, Inc. (“Marriott”), the manager of approximately 50% of our properties. For 2013, Marriott converted to reporting results based on a 12-month calendar year. During 2012, Marriott used a fiscal year ending on the Friday closest to December 31 and reported twelve weeks of operations for the first three quarters and sixteen weeks for the fourth quarter of the year for its Marriott-managed hotels. Accordingly, our first three quarters of operations in 2012 ended on March 23, June 15 and September 7. In contrast, managers of our other hotels, such as Ritz-Carlton, Hyatt, and Starwood, reported results on a monthly basis. During 2012, we did not report the month of operations that ended after our fiscal quarter until the following quarter for those hotels using a monthly reporting period because these hotel managers did not make mid-month results available to us. Accordingly, the month of operations that ended after our fiscal quarter was included in our quarterly results of operations in the following quarter for those calendar reporting hotel managers. As a result, our 2012 quarterly results of operations include results from hotel managers reporting results on a monthly basis as follows: first quarter (January, February), second quarter (March to May), third quarter (June to August) and fourth quarter (September to December).
	We will not restate the previously filed 2012 quarterly financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) because certain property-level operating expenses for our Marriott-managed properties necessary to restate operations are unavailable on a daily basis. Because we rely upon our operators for the hotel operating results used in our financial statements, the unavailability of this information on a calendar quarter basis for 2012 made restating our financial statements in accordance with GAAP unfeasible. Accordingly, the corresponding 2012 quarterly historical operating results are not comparable to our 2013 quarterly operating results.

Summary of Significant Accounting Policies	'
	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 unaudited condensed consolidated 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, 2012.
	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 unaudited condensed consolidated financial statements reflect all adjustments necessary to present fairly our financial position as of September 30, 2013, and the results of our operations for the quarter and year-to-date periods ended September 30, 2013 and September 7, 2012, respectively, and cash flows for the year-to-date periods ended September 30, 2013 and September 7, 2012. Interim results are not necessarily indicative of full year performance because of the impact of seasonal and short-term variations.

Earnings Per Common Share (Unit)	'
	3.	Earnings (Loss) Per Common Share (Unit)
	Host Inc. Earnings (Loss) Per Common Share
	Basic earnings (loss) per common share is computed by dividing net income (loss) attributable to common stockholders by the weighted average number of shares of Host Inc. common stock outstanding. Diluted earnings (loss) per common share is computed by dividing net income (loss) 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 (loss) per common share is shown below (in millions, except per share amounts):

	Host L.P. Earnings (Loss) Per Common Unit
	Basic earnings (loss) per common unit is computed by dividing net income (loss) attributable to common unitholders by the weighted average number of common units outstanding. Diluted earnings (loss) per common unit is computed by dividing net income (loss) 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 (loss) per unit is shown below (in millions, except per unit amounts):

	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 accumulated other comprehensive income (loss) within the equity portion of our balance sheets. The hedges were fully effective as of September 30, 2013.
	The following table summarizes our interest rate swap derivatives designated as cash flow hedges (in millions):
																	Change in Fair Value
	Transaction		Total			Maturity		Swapped		All-in Rate							Gain (Loss)															Gain (Loss)

	(2)              The swap was entered into in connection with the NZ$105 million ($87 million) mortgage loan on seven properties in New Zealand.
	Interest rate swap derivatives designated as fair value hedges. We have designated our fixed-to-floating interest rate swap derivatives as fair value hedges. We enter into these derivative instruments to hedge changes in the fair value of fixed-rate debt that occur as a result of changes in market interest rates. The derivatives are valued based on the prevailing market yield curve on the date of measurement. We also evaluate counterparty credit risk in the calculation of the fair value of the swaps. The changes in the fair value of the derivatives largely are offset by corresponding changes in the fair value of the underlying debt due to changes in the 3-month LIBOR rate, which change is recorded as an adjustment to the carrying amount of the debt. Any difference between the change in the fair value of the swap and the change in the fair value of the underlying debt, which difference was not significant for the periods presented, is considered the ineffective portion of the hedging relationship and is recognized in net income (loss).
	We have three fixed-to-floating interest rate swap agreements for an aggregate notional amount totaling $300 million. During both the quarters ended September 30, 2013 and September 7, 2012, the fair value of the swaps decreased $1 million. During the year-to-date periods ended September 30, 2013 and September 7, 2012, the fair value of the swaps decreased $4 million and $2 million, respectively.
	Foreign Investment Hedging Instruments. We have five 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 accumulated other comprehensive income (loss) within the equity portion of our balance sheets. 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):
	Currently Outstanding													Change in Fair Value – All Contracts
	Transaction		Total				Total					Forward		Gain (Loss)										Gain (Loss)

	In addition to the forward sale contracts, we have designated a portion of the foreign currency draws on our credit facility as hedges of net investments in foreign operations. Changes in fair value in the designated credit facility draws are recorded to accumulated other comprehensive income (loss) within the equity portion of our balance sheets.
	The following table summarizes the draws on our credit facility that are designated as hedges of net investments in international operations (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.

	Other Consolidated Partnerships. We consolidate five 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 $36 million and $34 million as of September 30, 2013 and December 31, 2012, respectively. Three 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, 2013 and December 31, 2012, the fair values of the non-controlling interests in the partnerships with finite lives were approximately $71 million and approximately $65 million, respectively.
	Net income (loss) attributable to non-controlling interests of consolidated partnerships is included in our determination of net income (loss). Net income (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, 2013 and September 7, 2012.  Net income (loss) attributable to non-controlling interests of third parties was $2 million and $1 million for the year-to-date periods ended September 30, 2013 and September 7, 2012, 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 issuable 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 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:

Legal Proceedings	'
	13.	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.
	Excluding the San Antonio litigation discussed below, 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 $11 million as of September 30, 2013 for liabilities related to legal proceedings and estimate that, in the aggregate, our losses related to these proceedings could be as much as $53 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.
	We also have accrued a loss contingency of approximately $68 million related to the litigation concerning the ground lease for the San Antonio Marriott Rivercenter. On June 28, 2013, the Texas Supreme Court issued an order denying our Petition for Review. The Court's procedures provide for the right to seek rehearing of such an order, and we have exercised that right. No assurances can be given as to the outcome of this appeal. In relation to this legal proceeding, we previously funded a court-ordered $25 million escrow reserve, which is included in restricted cash. For further detail on this legal proceeding, see Part II, Item 1, Legal Proceedings of this filing and Part I, Item 3, Legal Proceedings, of our Annual Report on Form 10-K for the year ended December 31, 2012.

	Host Inc. Earnings (Loss) Per Common Share
	Basic earnings (loss) per common share is computed by dividing net income (loss) attributable to common stockholders by the weighted average number of shares of Host Inc. common stock outstanding. Diluted earnings (loss) per common share is computed by dividing net income (loss) 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 (loss) per common share is shown below (in millions, except per share amounts):

	On May 31, 2013, we acquired the 426-room Hyatt Place Waikiki Beach in Honolulu, Hawaii for approximately $138.5 million. In connection with the acquisition, we incurred $1 million of acquisition costs and acquired a $0.5 million FF&E replacement fund.
