Basis of Presentation	'
	BASIS OF PRESENTATION
	The condensed consolidated financial statements present the results of operations, financial position, and cash flows of Marriott International, Inc. (“Marriott,” and together with its subsidiaries “we,” “us,” or the “Company”). In order to make this report easier to read, we refer throughout to (i) our Condensed Consolidated Financial Statements as our “Financial Statements,” (ii) our Condensed Consolidated Statements of Income as our “Income Statements,” (iii) our Condensed Consolidated Balance Sheets as our “Balance Sheets,” (iv) our properties, brands, or markets in the United States and Canada as “North America” or “North American,” and (v) our properties, brands, or markets outside of the United States and Canada as “International.” In addition, references throughout to numbered "Footnotes" refer to the numbered Notes in these Notes to Condensed Consolidated Financial Statements, unless otherwise noted.
	During the 2014 first quarter, we modified the information that our President and Chief Executive Officer, who is our "chief operating decision maker" ("CODM"), reviews to be consistent with our continent structure. This structure aligns our business around geographic regions and is designed to enable us to operate more efficiently and to accelerate worldwide growth. We changed our operating segments to reflect this continent structure and have revised our prior period business segment information accordingly. See Footnote No. 11, "Business Segments."
	Beginning with the 2014 first quarter, we reclassified amounts attributable to depreciation and amortization that we previously reported under the "General, administrative, and other" and "Owned, leased, and other-direct" captions of our Consolidated Statements of Income and presented these amounts in a separate "Depreciation and amortization" caption. We continue to report depreciation amounts that third party owners reimburse to us under "Reimbursed costs" in our Consolidated Statements of Income. In addition, in our Consolidated Statements of Cash Flows, we reclassified depreciation that third party owners reimburse to us from the "Depreciation and amortization" caption to the "Other" caption. We have reclassified the prior period amounts presented to conform to our 2014 first quarter presentation of these items.
	These condensed consolidated Financial Statements have not been audited. We have condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”). The financial statements in this report should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 (“2013 Form 10-K”). Certain terms not otherwise defined in this Form 10-Q have the meanings specified in our 2013 Form 10-K.
	Preparation of financial statements that conform with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements, the reported amounts of revenues and expenses during the reporting periods, and the disclosures of contingent liabilities. Accordingly, ultimate results could differ from those estimates.
	In 2013, we changed our financial reporting cycle to a calendar year-end reporting cycle and an end-of-month quarterly reporting cycle. Accordingly, our 2013 fiscal year began on December 29, 2012 (the day after the end of the 2012 fiscal year) and ended on December 31, 2013, and our 2013 quarters include the three month periods ended March 31, June 30, September 30, and December 31, except that the period ended March 31, 2013 also included December 29, 2012 through December 31, 2012.
	The table below shows the reporting periods as we refer to them in this report, their date ranges, and the number of days in each. As shown below, our 2014 first quarter had three fewer days of activity than our 2013 first quarter. Our 2014 calendar year will also have three fewer days of activity than our 2013 fiscal year.
	Reporting Period	Date Range	Number of Days
	2014 first quarter	January 1, 2014 - March 31, 2014	90
	2013 first quarter	December 29, 2012 - March 31, 2013	93
	2014	January 1, 2014 - December 31, 2014	365
	2013	December 29, 2012 - December 31, 2013	368
	Our Financial Statements reflect all normal and recurring adjustments necessary to present fairly our financial position as of March 31, 2014, and December 31, 2013, the results of our operations for the three months ended March 31, 2014, and March 31, 2013, and cash flows for the three months ended March 31, 2014, and March 31, 2013. Interim results may not be indicative of fiscal year performance because of seasonal and short-term variations. We have eliminated all material intercompany transactions and balances between entities consolidated in these Financial Statements.
	New Accounting Standards
	We do not expect that accounting standard updates issued to date and that are effective after March 31, 2014 will have a material effect on our Financial Statements.

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	INCOME TAXES
	Our effective tax rate decreased from 32.3% to 25.5% for the three months ended March 31, 2014 and included a $21 million favorable resolution of an issue with U.S. federal taxing authorities related to guest marketing. This benefit was partially offset by a $3 million benefit we recognized in the 2013 first quarter, which will not recur in 2014, due to retroactive provisions of the American Taxpayer Relief Act of 2012 and higher income before income taxes in the United States which were taxed at a higher rate.
	For the 2014 first quarter, our unrecognized tax benefits balance was $14 million, decreasing $20 million from year-end 2013. The unrecognized tax benefits balance included $12 million of tax positions that, if recognized, would impact our effective tax rate.
	We file income tax returns, including returns for our subsidiaries, in various jurisdictions around the world. The Internal Revenue Service ("IRS") has examined our federal income tax returns, and we have settled all issues for tax years through 2009. We participate in the IRS Compliance Assurance Program, which accelerates IRS examination of key transactions with the goal of resolving any issues before the taxpayer files its return. As a result, the audits of our open tax years 2010 through 2012 are complete, including all matters that could affect the Company's cash tax benefits related to our spin-off in 2011 of our timeshare operations and timeshare development business, while the 2013 and 2014 tax year audits are currently ongoing. Various foreign, state, and local income tax returns are also under examination by the applicable taxing authorities.
	We paid cash for income taxes, net of refunds of $25 million in the 2014 first quarter and $15 million in the 2013 first quarter.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]	'
Share-Based Compensation	'
	SHARE-BASED COMPENSATION
	Under our Stock and Cash Incentive Plan (the “Stock Plan”), we award: (1) stock options (our "Stock Option Program") to purchase our Class A Common Stock (our “common stock”); (2) stock appreciation rights (“SARs”) for our common stock (our “SAR Program”); (3) restricted stock units (“RSUs”) of our common stock; and (4) deferred stock units. We grant awards at exercise prices or strike prices that equal the market price of our common stock on the date of grant.
	We recorded share-based compensation expense for award grants of $25 million for the 2014 first quarter and $30 million for the 2013 first quarter. Deferred compensation costs related to unvested awards totaled $195 million at March 31, 2014 and $108 million at December 31, 2013.
	RSUs
	We granted 1.9 million RSUs during the 2014 first quarter to certain officers and key employees, and those units vest generally over four years in equal annual installments commencing one year after the grant date. We also granted 0.2 million performance-based RSUs ("PSUs") during the 2014 first quarter to certain named executive officers and their direct reports, subject to the satisfaction of certain performance conditions over, or at the end of, a three-year vesting period. RSUs, including PSUs, granted in the 2014 first quarter had a weighted average grant-date fair value of $51.
	SARs and Stock Options
	We granted 0.3 million SARs and 0.1 million stock options to officers and key employees during the 2014 first quarter. These SARs and options generally expire ten years after the grant date and both vest and may be exercised in cumulative installments of one quarter at the end of each of the first four years following the grant date. The weighted average grant-date fair value of SARs granted in the 2014 first quarter was $17 and the weighted average exercise price was $53. The weighted average grant-date fair value of stock options granted in the 2014 first quarter was $17 and the weighted average exercise price was $53.
	On the grant date, we use a binomial lattice-based valuation model to estimate the fair value of each SAR and option granted. This valuation model uses a range of possible stock price outcomes over the term of the SAR and option, discounted back to a present value using a risk-free rate. Because of the limitations with closed-form valuation models, such as the Black-Scholes model, we have determined that this more flexible binomial model provides a better estimate of the fair value of our options and SARs because it takes into account employee exercise behavior based on changes in the price of our stock and also allows us to use other dynamic assumptions.
	We used the following assumptions to determine the fair value of the SARs and stock options we granted during the 2014 first quarter:
	Expected volatility	30	%
	Dividend yield	1.14	%
	Risk-free rate	2.3 - 2.5%
	Expected term (in years)	7
	In making these assumptions, we base expected volatility on the historical movement of Marriott's stock price. We base risk-free rates on the corresponding U.S. Treasury spot rates for the expected duration at the date of grant, which we convert to a continuously compounded rate. The dividend yield assumption takes into consideration both historical levels and expectations of future payout. The weighted average expected terms for SARs and options are an output of our valuation model which utilizes historical data in estimating the period of time that the SARs and options are expected to remain unexercised. We calculate the expected terms for SARs and options for separate groups of retirement eligible and non-retirement eligible employees. Our valuation model also uses historical data to estimate exercise behaviors, which includes determining the likelihood that employees will exercise their SARs and options before expiration at a certain multiple of stock price to exercise price.
	Other Information
	As of the end of the 2014 first quarter, we had reserved 29 million shares under the Stock Plan, including 9 million shares under the Stock Option Program and the SAR Program.

Fair Value of Financial Instruments	'
	FAIR VALUE OF FINANCIAL INSTRUMENTS
	We believe that the fair values of our current assets and current liabilities approximate their reported carrying amounts. We show the carrying values and the fair values of noncurrent financial assets and liabilities that qualify as financial instruments, determined under current guidance for disclosures on the fair value of financial instruments, in the following table:
		At March 31, 2014						At December 31, 2013
	($ in millions)	Carrying			Fair Value			Carrying			Fair Value
		Amount						Amount
	Senior, mezzanine, and other loans	$	141		$	142		$	142		$	145
	Marketable securities and other debt securities	111			111			111			111
	Total long-term financial assets	$	252		$	253		$	253		$	256
	Senior Notes	$	(2,186	)	$	(2,310	)	$	(2,185	)	$	(2,302	)
	Commercial paper	(984		)	(984		)	(834		)	(834		)
	Other long-term debt	(121		)	(124		)	(123		)	(124		)
	Total long-term financial liabilities	$	(3,291	)	$	(3,418	)	$	(3,142	)	$	(3,260	)
	We estimate the fair value of our senior, mezzanine, and other loans, including the current portion, by discounting cash flows using risk-adjusted rates, both of which are Level 3 inputs.
	We carry our marketable securities at fair value. Our marketable securities include debt securities of the U.S. Government, its sponsored agencies and other U.S. corporations invested for our self-insurance programs, as well as shares of a publicly traded company, which we value using directly observable Level 1 inputs. The carrying value of these marketable securities at the end of our 2014 first quarter was $111 million. We also have a $65 million mandatorily redeemable preferred equity ownership interest in an entity that owns three hotels that we manage. We account for this investment as a debt security (with an amortized cost of $71 million at the end of the 2014 first quarter, including accrued interest income), and we included it in the "Marketable securities and other debt securities" caption in the preceding table. We estimated the $71 million fair value of this debt security by discounting cash flows using risk-adjusted rates, both of which are Level 3 inputs. The debt security matures in 2015 subject to annual extensions through 2018. We do not intend to sell the debt security and it is not more likely than not that we will be required to sell the investment before recovery of the amortized cost basis, which may be maturity.
	We estimate the fair value of our other long-term debt, including the current portion and excluding leases, using expected future payments discounted at risk-adjusted rates, both of which are Level 3 inputs. We determine the fair value of our senior notes using quoted market prices, which are directly observable Level 1 inputs. As noted in Footnote No. 8, "Long-term Debt," even though our commercial paper borrowings generally have short-term maturities of 30 days or less, we classify outstanding commercial paper borrowings as long-term based on our ability and intent to refinance them on a long-term basis. As we are a frequent issuer of commercial paper, we use pricing from recent transactions as Level 2 inputs in estimating fair value. At the end of the 2014 first quarter and year-end 2013, we determined that the carrying value of our commercial paper approximated its fair value due to the short maturity.
	See the “Fair Value Measurements” caption of Footnote No. 1, “Summary of Significant Accounting Policies” of our 2013 Form 10-K for more information on the input levels we use in determining fair value.

	We compute the effect of dilutive securities using the treasury stock method and average market prices during the period. We have excluded the following antidilutive stock options and SARs in our calculation of diluted earnings per share because their exercise prices were greater than the average market prices for the applicable periods:
	(a)	for the 2014 first quarter, 0.2 million options and SARs; and
	(b)	for the 2013 first quarter, 0.4 million options and SARs.

	All of our long-term debt was, and to the extent currently outstanding is, recourse to us but unsecured. Other debt in the preceding table includes capital leases, among other items.
	We are a party to a multicurrency revolving credit agreement (the “Credit Facility”) that provides for $2,000 million of aggregate borrowings to support general corporate needs, including working capital, capital expenditures, share repurchases, and letters of credit. The availability of the Credit Facility also supports our commercial paper program. Borrowings under the Credit Facility generally bear interest at LIBOR (the London Interbank Offered Rate) plus a spread, based on our public debt rating. We also pay quarterly fees on the Credit Facility at a rate based on our public debt rating. While any outstanding commercial paper borrowings and/or borrowings under our Credit Facility generally have short-term maturities, we classify the outstanding borrowings as long-term based on our ability and intent to refinance the outstanding borrowings on a long-term basis. The Credit Facility expires on July 18, 2018. See the “Cash Requirements and Our Credit Facilities” caption later in this report in the “Liquidity and Capital Resources” section for information on our available borrowing capacity at March 31, 2014.
	We show future principal payments for our debt as of the end of the 2014 first quarter in the following table:

	CONTINGENCIES
	Guarantees
	We issue guarantees to certain lenders and hotel owners, chiefly to obtain long-term management contracts. The guarantees generally have a stated maximum funding amount and a term of four to ten years. The terms of guarantees to lenders generally require us to fund if cash flows from hotel operations are inadequate to cover annual debt service or to repay the loan at the end of the term. The terms of the guarantees to hotel owners generally require us to fund if the hotels do not attain specified levels of operating profit. Guarantee fundings to lenders and hotel owners are generally recoverable as loans repayable to us out of future hotel cash flows and/or proceeds from the sale of hotels. We also enter into project completion guarantees with certain lenders in conjunction with hotels that we or our joint venture partners are building.
	We measure and record our liability for the fair value of a guarantee on a nonrecurring basis, that is when we issue or modify a guarantee, using Level 3 internally developed inputs. We generally base our calculation of the estimated fair value of a guarantee on the income approach or the market approach, depending on the type of guarantee. For the income approach, we use internally developed discounted cash flow and Monte Carlo simulation models that include the following assumptions, among others: projections of revenues and expenses and related cash flows based on assumed growth rates and demand trends; historical volatility of projected performance; the guaranteed obligations; and applicable discount rates. We base these assumptions on our historical data and experience, industry projections, micro and macro general economic condition projections, and our expectations. For the market approach, we use primarily market comparable data and assumptions about market capitalization rates, credit spreads, growth rates, and inflation. We show the maximum potential amount of our future guarantee fundings and the carrying amount of our liability for guarantees for which we are the primary obligor at March 31, 2014 in the following table:
	($ in millions)	Maximum Potential		Liability for  Guarantees
	Guarantee Type	Amount  of Future Fundings
	Debt service	$	77	$	3
	Operating profit	92		34
	Other	330		4
	Total guarantees where we are the primary obligor	$	499	$	41
	We included our liability at March 31, 2014 for guarantees for which we are the primary obligor on our Balance Sheet in “Other long-term liabilities.”
	Our guarantees listed in the preceding table that will not be in effect until the underlying properties open and we begin to operate the properties or certain other events occur consist of $20 million of debt service guarantees, $12 million of operating profit guarantees, and $315 million of other guarantees.
	Other guarantees that were not currently in effect include a "put option" agreement we entered into in the 2014 first quarter with the lenders for a construction loan. In conjunction with entering into a management agreement for the Times Square EDITION hotel in New York City (currently projected to open in 2017), and the hotel's ownership group obtaining acquisition financing and entering into agreements concerning future construction financing for the mixed use project (which includes both the hotel and adjacent retail space), we agreed in the first quarter of 2014 to provide credit support to the lenders through a "put option" agreement. Under this agreement, we granted the lenders the right, upon an uncured event of default by the hotel owner under, and an acceleration of, the mortgage loan, to require us to purchase the hotel component of the property during the first two years after opening for $315 million. The lenders may extend this period for up to three years to complete foreclosure if the loan has been accelerated and certain other conditions are met. We do not expect that the lenders will exercise this "put option." We have no ownership interest in this hotel.
	The preceding table does not include the following guarantees:
	•	$97 million of guarantees for Senior Living Services lease obligations of $71 million (expiring in 2018) and lifecare bonds of $26 million (estimated to expire in 2016), for which we are secondarily liable. Sunrise Senior Living, Inc. (“Sunrise”) is the primary obligor on both the leases and $4 million of the lifecare bonds; HCP, Inc., as successor by merger to CNL Retirement Properties, Inc. (“CNL”), is the primary obligor on $21 million of the lifecare bonds; and Five Star Senior Living is the primary obligor on the remaining $1 million of lifecare bonds. Before we sold the Senior Living Services business in 2003, these were our guarantees of obligations of our then consolidated Senior Living Services subsidiaries. Sunrise and CNL have indemnified us for any fundings we may be called upon to make under these guarantees. Our liability for these guarantees had a carrying value of $3 million at March 31, 2014. Sunrise previously provided us $5 million of cash collateral to cover potential exposure under the existing lease and bond obligations for 2012 and 2013. In conjunction with our consent of the extension in 2011 of certain lease obligations for an additional five-year term until 2018, Sunrise provided us an additional $1 million of cash collateral and an $85 million letter of credit issued by Key Bank to secure our exposure under the lease guarantees and certain other obligations of Sunrise. The letter of credit balance was $81 million at the end of the 2014 first quarter, which decreased as a result of lease payments made and lifecare bonds redeemed. During the extension term, Sunrise agreed to make an annual payment to us from the cash flow of the continuing lease facilities, subject to a $1 million annual minimum.
	•	Lease obligations, for which we became secondarily liable when we acquired the Renaissance Hotel Group in 1997, consisting of annual rent payments of approximately $6 million and total remaining rent payments through the initial term of approximately $34 million. Most of these obligations expire by the end of 2020. CTF Holdings Ltd. (“CTF”) had originally provided €35 million in cash collateral in the event that we are required to fund under such guarantees, approximately $4 million (€3 million) of which remained at March 31, 2014. Our exposure for the remaining rent payments through the initial term will decline to the extent that CTF obtains releases from the landlords or these hotels exit the system. Since the time we assumed these guarantees, we have not funded any amounts, and we do not expect to fund any amounts under these guarantees in the future.
	•	Certain guarantees and commitments relating to the timeshare business, which were outstanding at the time of the 2011 Timeshare spin-off and for which we became secondarily liable as part of the spin-off. These Marriott Vacations Worldwide Corporation ("MVW") payment obligations, for which we currently have a total exposure of $16 million, relate to various letters of credit and several other guarantees. MVW has indemnified us for these obligations. At the end of the 2014 first quarter, we expect these obligations will expire as follows: $1 million in 2014, $3 million in 2017, and $12 million (14 million Singapore Dollars) in 2022. We have not funded any amounts under these obligations, and do not expect to do so in the future. Our liability for these obligations had a carrying value of $2 million at March 31, 2014.
	•	A guarantee for a lease, originally entered into in 2000, for which we became secondarily liable in 2012 as a result of our sale of the ExecuStay corporate housing business to Oakwood Worldwide ("Oakwood"). Oakwood has indemnified us for the obligations under this guarantee. Our total exposure at the end of the 2014 first quarter for this guarantee is $6 million in future rent payments through the end of the lease in 2019. Our liability for this guarantee had a carrying value of $1 million at March 31, 2014.
	In addition to the guarantees described in the preceding paragraphs, in conjunction with financing obtained for specific projects or properties owned by joint ventures in which we are a party, we may provide industry standard indemnifications to the lender for loss, liability, or damage occurring as a result of the actions of the other joint venture owner or our own actions.
	Commitments and Letters of Credit
	In addition to the guarantees we note in the preceding paragraphs, as of March 31, 2014, we had the following commitments outstanding:
	•	A commitment to invest up to $10 million of equity for a noncontrolling interest in a partnership that plans to purchase North American full-service and limited-service properties, or purchase or develop hotel-anchored mixed-use real estate projects. We expect to fund $8 million of this commitment in 2014. We do not expect to fund the remaining $2 million of this commitment.
	•	A commitment to invest up to $22 million of equity for noncontrolling interests in a partnership that plans to purchase or develop limited-service properties in Asia. We expect to fund this commitment as follows: $10 million in 2014 and $12 million in 2015.
	•	A commitment, with no expiration date, to invest up to $11 million in a joint venture for development of a new property. We expect to fund this commitment as follows: $6 million in 2014 and $5 million in 2015.
	•	A commitment to invest $18 million in the renovation of a leased hotel. We expect to fund this commitment by the end of 2014.
	•	We have a right and under certain circumstances an obligation to acquire our joint venture partner’s remaining 45 percent interest in two joint ventures over the next seven years at a price based on the performance of the ventures. We made a $12 million (€9 million) deposit in conjunction with this contingent obligation in 2011 and $8 million (€6 million) in deposits in 2012. In the 2013 first quarter we acquired an additional five percent noncontrolling interest in each venture, applying $5 million (€4 million) of those deposits. The remaining deposits are refundable to the extent we do not acquire our joint venture partner’s remaining interests.
	•	Various commitments for the purchase of information technology hardware, software, as well as accounting, finance, and maintenance services in the normal course of business totaling $85 million. We expect to fund these commitments as follows: $78 million in 2014, $5 million in 2015, and $2 million in 2016. The majority of these commitments will be recovered through cost reimbursement charges to properties in our system.
	•	Several commitments aggregating $35 million with no expiration date and which we do not expect to fund.
	•	A commitment to invest up to $10 million under certain circumstances for additional mandatorily redeemable preferred equity ownership interest in an entity that owns three hotels. We may fund this commitment, which expires in 2015 subject to annual extensions through 2018; however, we have not yet determined the amount or timing of any potential funding.
	•	A $9 million loan commitment that we extended to the owner of a property to cover the cost of renovation shortfalls which we expect to fund in 2015. The commitment will expire at the end of the 2016 second quarter.
	At March 31, 2014, we had $78 million of letters of credit outstanding ($77 million outside the Credit Facility and $1 million under our Credit Facility), the majority of which were for our self-insurance programs. Surety bonds issued as of March 31, 2014, totaled $123 million, the majority of which federal, state and local governments requested in connection with our self-insurance programs.
	Legal Proceedings
	On January 19, 2010, several former Marriott employees (the "plaintiffs") filed a putative class action complaint against us and the Stock Plan (the "defendants"), alleging that certain equity awards of deferred bonus stock granted to the plaintiffs and other current and former employees for fiscal years 1963 through 1989 are subject to vesting requirements under the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), that are in certain circumstances more rapid than those set forth in the awards. The plaintiffs seek damages, class attorneys' fees and interest, with no amounts specified. The action is proceeding in the United States District Court for the District of Maryland (Greenbelt Division) and Dennis Walter Bond Sr. and Michael P. Steigman are the current named plaintiffs. The parties completed limited discovery concerning Marriott's defense of statute of limitations with respect to Mr. Bond and Mr. Steigman and completed discovery concerning class certification. We opposed plaintiffs' motion for class certification and sought summary judgment on the issue of statute of limitations in 2012. On August 9, 2013, the court denied our motion for summary judgment on the issue of statute of limitations and deferred its ruling on class certification. We moved to amend the court's judgment on our motion for summary judgment in order to certify an interlocutory appeal, which was denied. On January 7, 2014, the court denied plaintiffs' motion for class certification, and issued a Scheduling Order for full discovery of the remaining issues in this case. The parties filed a joint motion to modify the Scheduling Order on March 26, 2014. We and the Stock Plan have denied all liability, and while we intend to vigorously defend against the claims being made by the plaintiffs, we can give you no assurance about the outcome of this lawsuit. We currently cannot estimate the range of any possible loss to the Company because an amount of damages is not claimed, there is uncertainty as to the number of parties for whom the claims may be pursued, and the possibility of our prevailing on our statute of limitations defense on appeal may significantly limit any claims for damages.
	In March 2012, the Korea Fair Trade Commission ("KFTC") obtained documents from two of our managed hotels in Seoul, Korea in connection with an investigation which we believe is focused on pricing of hotel services within the Seoul region. Since then, the KFTC has conducted additional fact-gathering at those two hotels and also has collected information from another Marriott managed hotel located in Seoul. We understand that the KFTC also has sought documents from numerous other hotels in Seoul and other parts of Korea that we do not operate, own or franchise. We have not yet received a complaint or other legal process. We are cooperating with this investigation.

Segment Reporting [Abstract]	'
Business Segments	'
	BUSINESS SEGMENTS
	We are a diversified global lodging company. During the 2014 first quarter, we modified the information that our President and Chief Executive Officer, who is our CODM, reviews to be consistent with our continent structure. This structure aligns our business around geographic regions and is designed to enable us to operate more efficiently and to accelerate worldwide growth. As a result of modifying our reporting information, we revised our operating segments to eliminate our former Luxury segment, which we allocated between our existing North American Full-Service operating segment, and the following four new operating segments: Asia Pacific, Caribbean and Latin America, Europe, and Middle East and Africa.
	Although our North American Full-Service and North American Limited-Service segments meet the applicable accounting criteria to be reportable business segments, our four new operating segments do not meet the criteria for separate disclosure as reportable business segments. Accordingly, we combined our four new operating segments into an "all other" category which we refer to as "International" and have revised our prior period business segment information to conform to our new business segment presentation.
	As of the end the 2014 first quarter, our three business segments include the following brands:
	•	North American Full-Service: Marriott Hotels, Marriott Conference Centers, JW Marriott, Renaissance Hotels, Renaissance ClubSport, Gaylord Hotels, The Ritz-Carlton (together with residential properties associated with some of The Ritz-Carlton hotels), and Autograph Collection properties located in the United States and Canada;
	•	North American Limited-Service: Courtyard, Fairfield Inn & Suites, SpringHill Suites, Residence Inn, and TownePlace Suites properties located in the United States and Canada;
	•	International: Marriott Hotels, JW Marriott, Renaissance Hotels, Autograph Collection, Courtyard, AC Hotels by Marriott, Fairfield Inn & Suites, Residence Inn, The Ritz-Carlton (together with residential properties associated with some The Ritz-Carlton hotels), Bulgari Hotels & Resorts, EDITION and Marriott Executive Apartments properties located outside the United States and Canada.
	We evaluate the performance of our business segments based largely on the results of the segment without allocating corporate expenses, income taxes, or indirect general, administrative, and other expenses. We allocate gains and losses, equity in earnings or losses from our joint ventures, and divisional general, administrative, and other expenses to each of our segments. “Other unallocated corporate” represents a portion of our revenues, general, administrative, and other expenses, equity in earnings or losses, and other gains or losses that we do not allocate to our segments. It also includes license fees we receive from our credit card programs and license fees from MVW. Our CODM monitors assets for the consolidated company but does not use assets by business segment when assessing performance or making business segment resource allocations.

		ACQUISITIONS AND DISPOSITIONS
	2014 Acquisitions
	On the first day of our 2014 second quarter, we acquired Protea Hotels' brands and hotel management business ("Protea Hotels") for $193 million (ZAR 2.046 billion) in cash and recognized approximately: $183 million (ZAR 1.931 billion) in intangible assets consisting of deferred contract acquisition costs, a brand intangible, and goodwill; and $10 million (ZAR 115 million) of tangible assets consisting of property and equipment, equity method investments, and other current assets at the acquisition date. At the end of the 2014 first quarter, we transferred $192 million in cash to a third party in the form of an escrow deposit. As part of the transaction, Protea Hospitality Holdings created an independent property ownership company that retained ownership of the hotels Protea Hospitality Holdings formerly owned, and entered into long-term management and lease agreements with Marriott for these hotels. The property ownership company also retained a number of minority interests in other Protea-managed hotels. As a result of the transaction, we added over 100 hotels (over 10,000 rooms) across three brands in South Africa and six other Sub-Saharan African countries to our International segment portfolio and currently manage approximately 45 percent, franchise approximately 39 percent, and lease approximately 16 percent of those rooms.
	2014 Dispositions
	In the 2014 first quarter, we sold The London EDITION to a third party, received approximately $230 million in cash, and simultaneously entered into definitive agreements to sell The Miami and The New York EDITION hotels that we are currently developing to the same third party. The total sales price for the three EDITION hotels will be approximately $816 million. We expect to sell The Miami EDITION in the second half of 2014 and The New York EDITION in the first half of 2015, when we anticipate that construction will be complete. We will retain long-term management agreements for each of the three hotels sold. We did not reclassify The Miami EDITION or The New York EDITION assets and liabilities as held for sale because the hotels are under construction and not available for immediate sale in their present condition. In the 2014 first quarter, we evaluated the three hotels for recovery and subsequently recorded a $10 million impairment charge in the "Depreciation and amortization" caption of our Income Statement as our current cost estimates exceed our total fixed sales price. We did not allocate that charge to any of our segments.
	In the 2014 first quarter, we sold our right to acquire the landlord’s interest in a leased real estate property and certain attached assets of the property, consisting of $106 million (€77 million) in property and equipment and $48 million (€35 million) in liabilities. We received $62 million (€45 million) in cash and transferred $45 million (€33 million) of related obligations. We continue to operate the property under a long-term management agreement.

Fiscal Period	'
	In 2013, we changed our financial reporting cycle to a calendar year-end reporting cycle and an end-of-month quarterly reporting cycle. Accordingly, our 2013 fiscal year began on December 29, 2012 (the day after the end of the 2012 fiscal year) and ended on December 31, 2013, and our 2013 quarters include the three month periods ended March 31, June 30, September 30, and December 31, except that the period ended March 31, 2013 also included December 29, 2012 through December 31, 2012.
	The table below shows the reporting periods as we refer to them in this report, their date ranges, and the number of days in each. As shown below, our 2014 first quarter had three fewer days of activity than our 2013 first quarter. Our 2014 calendar year will also have three fewer days of activity than our 2013 fiscal year.
