Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Presentation	Basis of Presentation
	Wyndham Worldwide Corporation (“Wyndham” or the “Company”) is a global provider of hospitality services and products. The accompanying Consolidated Financial Statements include the accounts and transactions of Wyndham, as well as the entities in which Wyndham directly or indirectly has a controlling financial interest. The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America. All intercompany balances and transactions have been eliminated in the Consolidated Financial Statements.
	In presenting the Consolidated Financial Statements, management makes estimates and assumptions that affect the amounts reported and related disclosures. Estimates, by their nature, are based on judgment and available information. Accordingly, actual results could differ from those estimates. In management’s opinion, the Consolidated Financial Statements contain all normal recurring adjustments necessary for a fair presentation of annual results reported.
	Business Description
	The Company operates in the following business segments:
	•	Lodging—primarily franchises hotels in the upscale, upper midscale, midscale, economy and extended stay segments and provides hotel management services for full-service and select limited-service hotels.
	•	Vacation Exchange and Rentals—provides vacation exchange services and products to owners of intervals of vacation ownership interests (“VOIs”) and markets vacation rental properties primarily on behalf of independent owners.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	PRINCIPLES OF CONSOLIDATION
	When evaluating an entity for consolidation, the Company first determines whether an entity is within the scope of the guidance for consolidation of variable interest entities (“VIE”) and if it is deemed to be a VIE. If the entity is considered to be a VIE, the Company determines whether it would be considered the entity’s primary beneficiary. The Company consolidates those VIEs for which it has determined that it is the primary beneficiary. The Company will consolidate an entity not deemed a VIE upon a determination that it has a controlling financial interest. For entities where the Company does not have a controlling financial interest, the investments in such entities are classified as available-for-sale securities or accounted for using the equity or cost method, as appropriate.
	REVENUE RECOGNITION
	Lodging
	The principal source of revenues from franchising hotels is ongoing franchise fees, which are primarily comprised of royalty, marketing and reservation fees. Royalty, marketing and reservation fees are typically a percentage of gross room revenues of each franchised hotel and are recognized as revenue upon becoming due from the franchisee. An estimate of uncollectible ongoing royalty fees is charged to bad debt expense and included in operating expenses on the Consolidated Statements of Income. Lodging revenues also include initial franchise fees, which are recognized as revenues when all material services or conditions have been substantially performed, which is either when a franchised hotel opens for business or when a franchise agreement is terminated after it has been determined that the franchised hotel will not open.
	The Company’s franchise agreements also require the payment of marketing and reservation fees, which are intended to reimburse the Company for expenses associated with operating an international, centralized, brand-specific reservations system, e-commerce channels such as the Company’s brand.com websites, as well as access to third-party distribution channels, such as online travel agents, advertising and marketing programs, global sales efforts, operations support, training and other related services. Marketing and reservation fees are recognized as revenue upon becoming due from the franchisee. An estimate of uncollectible ongoing marketing and reservation fees is charged to bad debt expense and included in marketing and reservation expenses in the Consolidated Statements of Income.
	The Company is contractually obligated to expend the marketing and reservation fees it collects from franchisees in accordance with the franchise agreements; as such, revenues earned in excess of costs incurred are accrued as a liability for future marketing or reservation costs. Costs incurred in excess of revenues earned are expensed as incurred. In accordance with its franchise agreements, the Company includes an allocation of costs required to carry out marketing and reservation activities within marketing and reservation expenses.
	The Company also earns revenues from its Wyndham Rewards loyalty program when a member stays at a participating hotel. These revenues are derived from a fee the Company charges as a percentage of room revenues generated from such stay. This fee is recognized as revenue upon becoming due from the franchisee. Since the Company is obligated to expend the fees it collects from franchisees, revenues earned in excess of costs incurred are accrued as a liability for future costs to support the program.
	The Company also provides management services for hotels under management contracts, which offer all the benefits of a global brand and a full range of management, marketing and reservation services. In addition to the standard franchise services described above, the Company’s hotel management business provides hotel owners with professional oversight and comprehensive operations support services such as hiring, training and supervising the managers and employees that operate the hotels as well as annual budget preparation, financial analysis and extensive food and beverage services. The Company’s standard management agreement typically has a term of up to 25 years. The Company’s management fees are comprised of base fees, which are typically a specified percentage of gross revenues from hotel operations, and incentive fees, which are typically a specified percentage of a hotel’s gross operating profit. Management fee revenues are recognized when earned in accordance with the terms of the contract and recorded as a component of franchise fee revenues on the Consolidated Statements of Income. Management fee revenues were $11 million, $8 million and $7 million during 2014, 2013 and 2012, respectively. The Company also recognizes as revenue reimbursable payroll costs for operational employees at certain of the Company’s managed hotels. Although these costs are funded by hotel owners, accounting guidance requires the Company to report these fees on a gross basis as both revenues and expenses. The revenues are recorded as a component of service and membership fees while the offsetting expenses are reflected as a component of operating expenses on the Consolidated Statements of Income. As such, there is no effect on the Company’s operating income. Revenues related to these payroll costs were $148 million, $129 million and $91 million in 2014, 2013 and 2012, respectively.
	The Company also earns revenues from hotel ownership. The Company’s ownership portfolio is limited to two hotels in locations where we have developed or intend to develop timeshare units. Revenues earned from the Company’s owned hotels consist primarily of (i) gross room revenues, (ii) food and beverage services and (iii) on-site spa, casino, golf and shop revenues. These revenues are recognized upon the completion of services to its guests.
	Vacation Exchange and Rentals
	As a provider of vacation exchange services, the Company enters into affiliation agreements with developers of vacation ownership properties to allow owners of intervals of VOIs to trade their intervals for intervals at other properties affiliated with the Company’s vacation exchange business and, for some members, for other leisure-related services and products. Additionally, as a marketer of vacation rental properties, generally the Company enters into contracts for exclusive periods of time with property owners to market the rental of such properties to rental customers.
	The Company’s vacation exchange business derives a majority of its revenues from annual membership dues and exchange fees from members trading their intervals. Revenues from annual membership dues represent the annual fees from members who participate in the Company’s vacation exchange business and, for additional fees, have the right to exchange their intervals for intervals at other properties affiliated with the Company’s vacation exchange business and, for certain members, for other leisure-related services and products. The Company recognizes revenues from annual membership dues on a straight-line basis over the membership period during which delivery of publications, if applicable, and other services are provided to the members. Exchange fees are generated when members exchange their intervals for intervals at other properties affiliated with the Company’s vacation exchange business or for other leisure-related services and products. Exchange fees are recognized as revenues, net of expected cancellations, when the exchange requests have been confirmed to the member.
	The Company’s vacation rentals business primarily derives its revenues from fees, which generally average between 20% and 50% of the gross booking fees. For properties which the Company owns, manages or operates under long-term capital and operating leases (which represent less than 10% of the Company’s portfolio), the Company receives 100% of the revenues. The majority of the time, the Company acts on behalf of the owners of the rental properties to generate the Company’s fees. The Company provides reservation services to the independent property owners and receives the agreed-upon fee for the services provided. The Company remits the gross rental fee received from the renter to the independent property owner, net of the Company’s agreed-upon fee. Revenues from such fees that are recognized in the period that the rental reservation is made, are recorded net of expected cancellations.
	Cancellations for 2014, 2013 and 2012 each totaled less than 5% of rental transactions booked. Upon confirmation of the rental reservation, the rental customer and property owner generally have a direct relationship for additional services to be performed. The Company also earns rental fees in connection with properties which it owns, manages or operates and such fees are recognized ratably over the rental customer’s stay, as this is the point at which the service is rendered. The Company’s revenues are earned when evidence of an arrangement exists, delivery has occurred or the services have been rendered, the seller’s price to the buyer is fixed or determinable, and collectability is reasonably assured.
	Vacation Ownership
	The Company develops, markets and sells VOIs to individual consumers, provides property management services at resorts and provides consumer financing in connection with the sale of VOIs. The Company’s vacation ownership business derives the majority of its revenues from sales of VOIs and derives other revenues from consumer financing and property management. The Company’s sales of VOIs are either cash sales or developer-financed sales. In order for the Company to recognize revenues from VOI sales under the full accrual method of accounting described in the guidance for sales of real estate for fully constructed inventory, a binding sales contract must have been executed, the statutory rescission period must have expired (after which time the purchasers are not entitled to a refund except for non-delivery by the Company), receivables must have been deemed collectible and the remainder of the Company’s obligations must have been substantially completed. In addition, before the Company recognizes any revenues from VOI sales, the purchaser of the VOI must have met the initial investment criteria and, as applicable, the continuing investment criteria, by executing a legally binding financing contract. A purchaser has met the initial investment criteria when a minimum down payment of 10% is received by the Company.
	In accordance with the guidance for accounting for real estate time-sharing transactions, the Company must also take into consideration the fair value of certain incentives provided to the purchaser when assessing the adequacy of the purchaser’s initial investment. In those cases where financing is provided to the purchaser by the Company, the purchaser is obligated to remit monthly payments under financing contracts that represent the purchaser’s continuing investment.
	If all of the criteria for a VOI sale to qualify under the full accrual method of accounting have been met, as discussed above, except that construction of the VOI purchased is not complete, the Company recognizes revenues using the percentage-of-completion (“POC”) method of accounting provided that the preliminary construction phase is complete and that a minimum sales level has been met (to assure that the property will not revert to a rental property). The preliminary stage of development is deemed to be complete when the engineering and design work is complete, the construction contracts have been executed, the site has been cleared, prepared and excavated, and the building foundation is complete. The completion percentage is determined by the proportion of real estate inventory costs incurred to total estimated costs. These estimated costs are based upon historical experience and the related contractual terms. The remaining revenues and related costs of sales, including commissions and direct expenses, are deferred and recognized as the remaining costs are incurred. During 2014, $12 million of revenues were deferred under the POC method of accounting. During 2013, an immaterial amount of revenues were deferred under the POC method of accounting.
	The Company also offers consumer financing as an option to customers purchasing VOIs, which are typically collateralized by the underlying VOI. The contractual terms of Company-provided financing agreements require that the contractual level of annual principal payments be sufficient to amortize the loan over a customary period for the VOI being financed, which is generally 10 years and payments under the financing contracts begin within 45 days of the sale and receipt of the minimum down payment of 10%. An estimate of uncollectible amounts is recorded at the time of the sale with a charge to the provision for loan losses, which is classified as a reduction of VOI sales on the Consolidated Statements of Income. The interest income earned from the financing arrangements is earned on the principal balance outstanding over the life of the arrangement and is recorded within consumer financing on the Consolidated Statements of Income.
	The Company also provides day-to-day-management services, including oversight of housekeeping services, maintenance and certain accounting and administrative services for property owners’ associations and clubs. In some cases, the Company’s employees serve as officers and/or directors of these associations and clubs in accordance with their by-laws and associated regulations. The Company receives fees for such property management services which are generally based upon total costs to operate such resorts. Fees for property management services typically approximate 10% of budgeted operating expenses. Property management fee revenues are recognized when earned in accordance with the terms of the contract and are recorded as a component of service and membership fees on the Consolidated Statements of Income. Property management revenues, which are comprised of management fee revenue and reimbursable revenue, were $581 million, $567 million and $460 million during 2014, 2013 and 2012, respectively. Management fee revenues were $288 million, $290 million and $225 million during 2014, 2013 and 2012, respectively. Reimbursable revenues, which are based upon certain reimbursable costs with no added margin, were $293 million, $277 million and $235 million during 2014, 2013 and 2012, respectively. These reimbursable costs principally relate to the payroll costs for management of the associations, club and resort properties where the Company is the employer and are reflected as a component of operating expenses on the Consolidated Statements of Income. During each of 2014, 2013 and 2012, one of the associations that the Company manages paid Wyndham Exchange & Rentals $19 million for exchange services.
	Other Items
	The Company records marketing and reservation revenues, Wyndham Rewards revenues, RCI Elite Rewards revenues and hotel/property management services revenues for its Lodging, Vacation Ownership and Vacation Exchange and Rentals segments, in accordance with the guidance for reporting revenues gross as a principal versus net as an agent, which requires that these revenues be recorded on a gross basis.

Deferred VOI trial fees are payments received in advance for a trial VOI, which allows customers to utilize a VOI typically within one year of purchase. Deferred incentive fees represent payments received in advance for additional travel related services and products at the time of a VOI sale. Revenue is recognized when a customer utilizes the additional services and products, which is typically within two years of a VOI sale. Deferred vacation rental fees represent payments received in advance of a rental customer’s stay that are recognized as revenue when the rental stay occurs, which is typically within six months of the confirmation date. Deferred initial franchise fees are recognized when all material services or conditions have been performed which is typically within two years.
	INCOME TAXES
	The Company recognizes deferred tax assets and liabilities using the asset and liability method, under which deferred tax assets and liabilities are calculated based upon the temporary differences between the financial statement and income tax bases of assets and liabilities using currently enacted tax rates. These differences are based upon estimated differences between the book and tax basis of the assets and liabilities for the Company as of December 31, 2014 and 2013.
	The Company’s deferred tax assets are recorded net of a valuation allowance when, based on the weight of available evidence, it is more likely than not that some portion or all of the recorded deferred tax assets will not be realized in future periods. Decreases to the valuation allowance are recorded as reductions to the Company’s provision for income taxes and increases to the valuation allowance result in additional provision for income taxes. The realization of the Company’s deferred tax assets, net of the valuation allowance, is primarily dependent on estimated future taxable income. A change in the Company’s estimate of future taxable income may require an addition to or reduction from the valuation allowance.
	For tax positions the Company has taken or expects to take in a tax return, the Company applies a more likely than not threshold, under which the Company must conclude a tax position is more likely than not to be sustained, assuming that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information, in order to recognize or continue to recognize the benefit. In determining the Company’s provision for income taxes, the Company uses judgment, reflecting its estimates and assumptions, in applying the more likely than not threshold.
	CASH AND CASH EQUIVALENTS
	The Company considers highly-liquid investments purchased with an original maturity of three months or less to be cash equivalents.
	RESTRICTED CASH
	The largest portion of the Company’s restricted cash relates to securitizations. The remaining portion is comprised of cash held in escrow accounts primarily related to the Company’s vacation ownership business.
	Securitizations: In accordance with the contractual requirements of the Company’s various vacation ownership contract receivable securitizations, a dedicated lockbox account, subject to a blocked control agreement, is established for each securitization. At each month end, the total cash in the collection account from the previous month is analyzed and a monthly servicer report is prepared by the Company, which details how much cash should be remitted to the note holders for principal and interest payments, and any cash remaining is transferred by the trustee back to the Company. Additionally, as required by various securitizations, the Company holds an agreed-upon percentage of the aggregate outstanding principal balances of the VOI contract receivables collateralizing the asset-backed notes in a segregated trust (or reserve) account as credit enhancement. Each time a securitization closes and the Company receives cash from the note holders, a portion of the cash is deposited in the reserve account. Such amounts were $96 million and $92 million, of which $75 million and $64 million is recorded within other current assets and $21 million and $28 million is recorded within other non-current assets as of December 31, 2014 and 2013, respectively, on the Consolidated Balance Sheets.
	Escrow Deposits: Laws in most U.S. states require the escrow of down payments on VOI sales, with the typical requirement mandating that the funds be held in escrow until the rescission period expires. As sales transactions are consummated, down payments are collected and are subsequently placed in escrow until the rescission period has expired. Depending on the state, the rescission period can be as short as 3 calendar days or as long as 15 calendar days. In certain states, the escrow laws require that 100% of VOI purchaser funds (excluding interest payments, if any), be held in escrow until the deeding process is complete. Where possible, the Company utilizes surety bonds in lieu of escrow deposits. Escrow deposit amounts were $51 million and $57 million as of December 31, 2014 and 2013, respectively, which is recorded within other current assets on the Consolidated Balance Sheets.
	RECEIVABLE VALUATION
	Trade receivables
	The Company provides for estimated bad debts based on its assessment of the ultimate realizability of receivables, considering historical collection experience, the economic environment and specific customer information. When the Company determines that an account is not collectible, the account is written-off to the allowance for doubtful accounts. The following table illustrates the Company’s allowance for doubtful accounts activity for the year ended December 31:
		2014			2013			2012
	Beginning balance	$	209		$	213		$	207
	Bad debt expense	48			57			53
	Write-offs	(86		)	(64		)	(49		)
	Translation and other adjustments	(2		)	3			2
	Ending balance	$	169		$	209		$	213
	Vacation ownership contract receivables
	In the Company’s Vacation Ownership segment, the Company provides for estimated vacation ownership contract receivable defaults at the time of VOI sales by recording a provision for loan losses as a reduction of VOI sales on the Consolidated Statements of Income. The Company assesses the adequacy of the allowance for loan losses based on the historical performance of similar vacation ownership contract receivables. The Company uses a technique referred to as static pool analysis, which tracks defaults for each year’s sales over the entire life of those contract receivables. The Company considers current defaults, past due aging, historical write-offs of contracts and consumer credit scores (FICO scores) in the assessment of borrower’s credit strength and expected loan performance. The Company also considers whether the historical economic conditions are comparable to current economic conditions. If current or expected future conditions differ from the conditions in effect when the historical experience was generated, the Company adjusts the allowance for loan losses to reflect the expected effects of the current environment on the collectability of the Company’s vacation ownership contract receivables.
	LOYALTY PROGRAMS
	The Company operates a number of loyalty programs including Wyndham Rewards, RCI Elite Rewards and other programs. Wyndham Rewards members primarily accumulate points by staying in hotels franchised under one of the Company’s lodging brands. Wyndham Rewards and RCI Elite Rewards members accumulate points by purchasing everyday services and products from the various businesses that participate in the program.
	Members may redeem their points for hotel stays, airline tickets, rental cars, resort vacations, electronics, sporting goods, movie and theme park tickets, gift certificates, vacation ownership maintenance fees and annual membership dues and exchange fees for transactions. The points cannot be redeemed for cash. The Company earns revenue from these programs (i) when a member stays at a participating hotel, from a fee charged by the Company to the franchisee, which is based upon a percentage of room revenues generated from such stay or (ii) based upon a percentage of the members’ spending on the co-branded credit cards and such revenues are paid to the Company by a third-party issuing bank. The Company also incurs costs to support these programs, which primarily relate to marketing expenses to promote the programs, costs to administer the programs and costs of members’ redemptions.
	As members earn points through the Company’s loyalty programs, the Company records a liability of the estimated future redemption costs, which is calculated based on (i) an estimated cost per point and (ii) an estimated redemption rate of the overall points earned, which is determined through historical experience, current trends and the use of an actuarial analysis. Revenues relating to the Company’s loyalty programs are recorded in other revenues in the Consolidated Statements of Income and amounted to $142 million, $113 million and $78 million, while total expenses amounted to $112 million, $93 million and $73 million in 2014, 2013 and 2012, respectively. The liability for estimated future redemption costs as of December 31, 2014 and 2013 amounted to $62 million and $52 million, respectively, and is included in accrued expenses and other current liabilities and other non-current liabilities in the Consolidated Balance Sheets.
	INVENTORY
	Inventory primarily consists of real estate and development costs of completed VOIs, VOIs under construction, land held for future VOI development, vacation ownership properties, vacation credits and inventory sold subject to conditional repurchase. The Company applies the relative sales value method for relieving VOI inventory and recording the related cost of sales. Under the relative sales value method, cost of sales is calculated as a percentage of net sales using a cost-of-sales percentage ratio of total estimated development cost to total estimated VOI revenue, including estimated future revenue and incorporating factors such as changes in prices and the recovery of VOIs generally as a result of contract receivable defaults. The effect of such changes in estimates under the relative sales value method is accounted for on a retrospective basis through corresponding current-period adjustments to inventory and cost of sales. Inventory is stated at the lower of cost, including capitalized interest, property taxes and certain other carrying costs incurred during the construction process, or net realizable value. Capitalized interest was $2 million, less than $1 million and $1 million in 2014, 2013 and 2012, respectively.
	ADVERTISING EXPENSE
Advertising costs are generally expensed in the period incurred. Advertising expenses, which are primarily recorded within marketing and reservation expenses on the Consolidated Statements of Income, were $170 million, $146 million and $105 million in 2014, 2013 and 2012, respectively.
USE OF ESTIMATES AND ASSUMPTIONS
The preparation of the Consolidated Financial Statements requires the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in the Consolidated Financial Statements and accompanying notes. Although these estimates and assumptions are based on the Company’s knowledge of current events and actions the Company may undertake in the future, actual results may ultimately differ from estimates and assumptions.
DERIVATIVE INSTRUMENTS
The Company uses derivative instruments as part of its overall strategy to manage its exposure to market risks primarily associated with fluctuations in foreign currency exchange rates and interest rates. As a matter of policy, the Company does not use derivatives for trading or speculative purposes. All derivatives are recorded at fair value either as assets or liabilities. Changes in fair value of derivatives not designated as hedging instruments and of derivatives designated as fair value hedging instruments are recognized currently in operating income and net interest expense, based upon the nature of the hedged item, in the Consolidated Statements of Income. The effective portion of changes in fair value of derivatives designated as cash flow hedging instruments is recorded as a component of other comprehensive income. The ineffective portion is reported immediately in earnings as a component of operating expense, based upon the nature of the hedged item. Amounts included in other comprehensive income are reclassified into earnings in the same period during which the hedged item affects earnings.
PROPERTY AND EQUIPMENT
Property and equipment (including leasehold improvements) are recorded at cost, and presented net of accumulated depreciation and amortization. Depreciation, recorded as a component of depreciation and amortization on the Consolidated Statements of Income, is computed utilizing the straight-line method over the lesser of the lease terms or estimated useful lives of the related assets. Amortization of leasehold improvements, also recorded as a component of depreciation and amortization, is computed utilizing the straight-line method over the lesser of the estimated benefit period of the related assets or the lease terms. Useful lives are generally 30 years for buildings, up to 20 years for leasehold improvements, from 15 to 30 years for vacation rental properties and from 3 to 7 years for furniture, fixtures and equipment.
The Company capitalizes the costs of software developed for internal use in accordance with the guidance for accounting for costs of computer software developed or obtained for internal use. Capitalization of software developed for internal use commences during the development phase of the project. The Company generally amortizes software developed or obtained for internal use on a straight-line basis, from 3 to 5 years, commencing when such software is substantially ready for use. The net carrying value of software developed or obtained for internal use was $190 million and $158 million as of December 31, 2014 and 2013, respectively. Capitalized interest was $4 million, $5 million and $4 million in 2014, 2013 and 2012, respectively.
IMPAIRMENT OF LONG-LIVED ASSETS
The Company has goodwill and other indefinite-lived intangible assets recorded in connection with business combinations. The Company annually (during the fourth quarter of each year subsequent to completing the Company’s annual forecasting process), or more frequently if circumstances indicate that the value of goodwill may be impaired, reviews the reporting units’ carrying values as required by the guidance for goodwill and other indefinite-lived intangible assets. In accordance with the guidance, the Company has determined that its reporting units are the same as its reportable segments.
Under current accounting guidance, goodwill and other intangible assets with indefinite lives are not subject to amortization. However, goodwill and other intangibles with indefinite lives are subject to fair value-based rules for measuring impairment, and resulting write-downs, if any, are reflected in operating expense. The Company has goodwill recorded at its lodging, vacation exchange and rentals and vacation ownership reporting units. The Company completed its annual goodwill impairment test by performing a qualitative analysis for each of its reporting units as of October 1, 2014 and determined that no impairment exists.
The Company also evaluates the recoverability of its other long-lived assets, including property and equipment and amortizable intangible assets, if circumstances indicate impairment may have occurred, pursuant to guidance for impairment or disposal of long-lived assets. This analysis is performed by comparing the respective carrying values of the assets to the current and expected future cash flows, on an undiscounted basis, to be generated from such assets. Property and equipment is evaluated separately within each segment. If such analysis indicates that the carrying value of these assets is not recoverable, the carrying value of such assets is reduced to fair value.
ACCOUNTING FOR RESTRUCTURING ACTIVITIES
The Company’s restructuring actions require it to make significant estimates in several areas including (i) expenses for severance and related benefit costs, (ii) the ability to generate sublease income, as well as its ability to terminate lease obligations and (iii) contract terminations. The amount that the Company has accrued as of December 31, 2014 represents its best estimate of the obligations incurred in connection with these actions, but could be subject to change due to various factors including market conditions and the outcome of negotiations with third parties.
ACCUMULATED OTHER COMPREHENSIVE INCOME
Accumulated other comprehensive income (“AOCI”) consists of accumulated foreign currency translation adjustments, accumulated unrealized gains and losses on derivative instruments designated as cash flow hedges and pension related costs. Foreign currency translation adjustments exclude income taxes related to indefinite investments in foreign subsidiaries. Assets and liabilities of foreign subsidiaries having non-U.S.-dollar functional currencies are translated at exchange rates at the Consolidated Balance Sheet dates. Revenues and expenses are translated at average exchange rates during the periods presented. The gains or losses resulting from translating foreign currency financial statements into U.S. dollars, net of hedging gains or losses and taxes, are included in AOCI on the Consolidated Balance Sheets. Gains or losses resulting from foreign currency transactions are included in the Consolidated Statements of Income.
STOCK-BASED COMPENSATION
In accordance with the guidance for stock-based compensation, the Company measures all employee stock-based compensation awards using a fair value method and records the related expense in its Consolidated Statements of Income.
EQUITY EARNINGS AND OTHER INCOME
The Company applies the equity method of accounting when it has the ability to exercise significant influence over operating and financial policies of an investee. The Company recorded $2 million, $3 million and $0 of net earnings from such investments during 2014, 2013 and 2012, respectively, in other income, net on the Consolidated Statements of Income.
During 2014, the Company recorded $5 million of income primarily related to the sale of non-strategic assets and other miscellaneous royalties at its vacation ownership business. During 2013, the Company recorded $3 million of income primarily related to other miscellaneous royalties at its vacation ownership business. In addition, during 2012, the Company recorded $8 million of income primarily related to the settlement of a business disruption claim related to the Gulf of Mexico spill in 2010 and the reversal of allowance associated with previously divested asset.
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
Intangibles - Goodwill and Other. In July 2012, the Financial Accounting Standards Board (the “FASB”) issued guidance on the testing of indefinite-lived intangible assets for impairment, which is intended to reduce the cost and complexity of the impairment test for indefinite-lived intangible assets by providing an entity with the option to first assess qualitatively whether it is necessary to perform the impairment test that is currently in place. An entity would not be required to quantitatively calculate the fair value of an indefinite-lived intangible asset unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. This guidance was effective for interim and annual impairment tests beginning after September 15, 2012, with early adoption permitted. The Company adopted the guidance on October 1, 2012, as required. There was no material impact on the Consolidated Financial Statements resulting from the adoption.
Comprehensive Income. In February 2013, the FASB issued guidance to improve the reporting of amounts reclassified out of AOCI. The guidance amends the presentation of changes in AOCI and requires an entity to disaggregate the total change of each component of other comprehensive income either on the face of the statement of income or as a separate disclosure in the notes. This guidance is effective prospectively for fiscal years beginning after December 15, 2012. The Company adopted the guidance on January 1, 2013, as required. There was no material impact on its Consolidated Financial Statements resulting from the adoption.
Foreign Currency Matters. In March 2013, the FASB issued guidance on a parent’s accounting for the cumulative translation adjustment upon derecognition of a subsidiary or group of assets within a foreign entity. The guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. This guidance is effective prospectively for fiscal years beginning after December 15, 2013 and for interim periods within those fiscal years. The Company adopted the guidance on January 1, 2014, as required. There was no material impact on the Consolidated Financial Statements resulting from the adoption.
Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. In April 2014, the FASB issued guidance on reporting discontinued operations and disclosures of disposals of components of an entity. This guidance changes the criteria for determining which disposals can be presented as discontinued operations and enhances the related disclosure requirements. This guidance is effective for fiscal years beginning after December 15, 2014 and for interim periods within those fiscal years, with early adoption permitted. The Company will adopt this guidance on January 1, 2015, and it believes the adoption of this guidance will not have a material impact on the Consolidated Financial Statements.
Revenue from Contracts with Customers. In May 2014, the FASB issued guidance on revenue from contracts with customers. The guidance outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This guidance is effective for fiscal years beginning after December 15, 2016 and for interim periods within those fiscal years. The Company is currently evaluating the impact of the adoption of this guidance on the Consolidated Financial Statements.
Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern. In August 2014, the FASB issued guidance on disclosure of uncertainties about an entity’s ability to continue as a going concern. This guidance addresses management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. The guidance is effective for fiscal years ending after December 15, 2016 and for interim periods within those fiscal years, with early adoption permitted. The Company will adopt this guidance on January 1, 2015, and it believes the adoption of this guidance will not have an impact on the Consolidated Financial Statements.

	(a)	Includes unvested dilutive restricted stock units (“RSUs”) which are subject to future forfeitures.
	(b)	Excludes 12,000, 74,000 and 98,000 stock options and stock-settled stock appreciation rights (“SSARs”) for the years ended 2014, 2013 and 2012, respectively, as they would have been anti-dilutive to EPS.
	(c)	Excludes 422,000, 492,000 and 606,000 performance vested restricted stock units (“PSUs”) for the years ended 2014, 2013 and 2012, respectively, as the Company had not met the required performance metrics.
	(d)	For each of the quarterly periods ended March 31, June 30, September 30 and December 31, 2014, 2013 and 2012, the Company paid cash dividends of $0.35, $0.29 and $0.23 per share, respectively.
	Stock Repurchase Program
	On October 22, 2014, the Company’s Board of Directors authorized an increase of $1.0 billion to the Company’s existing stock repurchase program. As of December 31, 2014, the total authorization of the program was $4.0 billion.
	The following table summarizes stock repurchase activity under the current stock repurchase program (in millions, except per share data):
		Shares		Cost			Average Price Per Share
	As of December 31, 2013	62.7		$	2,410		$	38.44
	For the year ended December 31, 2014	8.6		652			75.79
	As of December 31, 2014	71.3		$	3,062		42.94
	The Company had $1.0 billion remaining availability in its program as of December 31, 2014. The total capacity of the program was increased by proceeds received from stock option exercises.
	As of December 31, 2014, the Company has repurchased under its current and prior stock repurchase plans, a total of 96 million shares at an average price of $40.17 for a cost of $3.9 billion since its separation from Cendant (“Separation”).

Business Combinations [Abstract]
Acquistions	Acquisitions
	Assets acquired and liabilities assumed in business combinations were recorded on the Consolidated Balance Sheets as of the respective acquisition dates based upon their estimated fair values at such dates. The results of operations of businesses acquired by the Company have been included in the Consolidated Statements of Income since their respective dates of acquisition. The excess of the purchase price over the estimated fair values of the underlying assets acquired and liabilities assumed was allocated to goodwill. In certain circumstances, the allocations of the excess purchase price are based upon preliminary estimates and assumptions. Accordingly, the allocations may be subject to revision when the Company receives final information, including appraisals and other analyses. Any revisions to the fair values during the allocation period will be recorded by the Company as further adjustments to the purchase price allocations. Although, in certain circumstances, the Company has substantially integrated the operations of its acquired businesses, additional future costs relating to such integration may occur. These costs may result from integrating operating systems, relocating employees, closing facilities, reducing duplicative efforts and exiting and consolidating other activities. These costs will be recorded on the Consolidated Statements of Income as expenses.
	2014 ACQUISITIONS
	During 2014, the Company completed four acquisitions for $32 million in cash, net of cash acquired, and paid an additional $2 million of contingent consideration related to prior year acquisitions. The preliminary purchase price allocations resulted in the recognition of $14 million of property, $9 million of inventory and $3 million of definite-lived intangible assets with a weighted average life of 13 years, all of which were allocated to the Company’s Vacation Ownership segment. In addition, the Company recognized $2 million of goodwill, none of which is expected to be deductible for tax purposes, and $3 million of definite-lived intangible assets with a weighted average life of 12 years, both of which were allocated to the Company’s Vacation Exchange and Rentals segment. These acquisitions were not material to the Company’s results of operations, financial position or cash flows.
	2013 ACQUISITIONS
	Midtown 45, NYC Property. During January 2013, the Company entered into an agreement with a third-party partner whereby the partner acquired the Midtown 45 property in New York City (“Midtown 45”) for $115 million through a special purpose entity (“SPE”). The Company is considered to be the primary beneficiary of the SPE and therefore the Company consolidates the SPE within its financial statements. The Company is managing and operating the property for rental purposes while the Company converts it into VOI inventory. The SPE’s purchase price allocation for this property resulted in the recognition of $115 million of property and equipment, all of which was assigned to the Company’s Vacation Ownership segment. Acquisition-related costs of $2 million are included in operating expenses in the accompanying Consolidated Statement of Income for 2013. This SPE transaction is consistent with the Company’s strategy to replenish VOI inventory utilizing Wyndham Asset Affiliation Models (“WAAM”) Just-in-Time. The consolidation of the SPE was not material to the Company’s results of operations, financial position or cash flows (see Note 14 - Variable Interest Entities for more detailed information).
	In addition, during 2013, the Company completed two other acquisitions for $14 million in cash, net of cash acquired. The preliminary purchase price allocations resulted in the recognition of $12 million of goodwill, none of which is expected to be deductible for tax purposes, $8 million of definite-lived intangible assets with a weighted average life of 10 years and $1 million of trademarks, all of which were assigned to the Company’s Vacation Exchange and Rentals segment. These acquisitions were not material to the Company’s results of operations, financial position or cash flows.

	During 2013, the Company recorded $8 million of non-cash impairment charges at its lodging business primarily related to a partial write-down of the Hawthorn trademark resulting from slower than expected growth in the brand. As of December 31, 2013, the remaining $28 million carrying amount for the Hawthorn trademark was equal to its estimated fair value as of the date of impairment. The Company utilized a discounted cash flow model for the brand using assumptions of future operating performance, growth and discount rate. During 2012, the Company recorded an $8 million non-cash impairment charge resulting from the decision to rebrand the ResortQuest and Steamboat Resorts trade names to the Wyndham Vacation Rentals brand. Such amounts are included within loss on sale and asset impairments on the Consolidated Statements of Income (see Note 22 — Restructuring and Impairments for more information).
	Goodwill
	During the fourth quarters of 2014, 2013 and 2012, the Company performed its annual goodwill impairment test and determined that no impairment existed as the fair value of goodwill at its reporting units was in excess of the carrying value.
	The changes in the carrying amount of goodwill are as follows:

	Franchise fee revenues of $632 million, $599 million and $583 million on the Consolidated Statements of Income for 2014, 2013 and 2012, respectively, include initial franchise fees of $12 million during each year.
	As part of ongoing franchise fees, the Company receives marketing and reservation fees from its lodging franchisees, which generally are calculated based on a specified percentage of gross room revenues. Such fees totaled $294 million, $291 million and $282 million during 2014, 2013 and 2012, respectively, and are recorded within franchise fees on the Consolidated Statements of Income. In accordance with the franchise agreements, the Company is contractually obligated to expend the marketing and reservation fees it collects from franchisees for the operation of an international, centralized, brand-specific reservation system and for marketing purposes such as advertising, promotional and co-marketing programs, and training for the respective franchisees. Additionally, the Company is required to provide certain services to its franchisees, including referrals, technology and volume purchasing.
	The Company may, at its discretion, provide development advances to certain of its franchisees or hotel owners in its managed business in order to assist such franchisees/hotel owners in converting to one of the Company’s brands, building a new hotel to be flagged under one of the Company’s brands or in assisting in other franchisee expansion efforts. Provided the franchisee/hotel owner is in compliance with the terms of the franchise/management agreement, all or a portion of the development advance may be forgiven by the Company over the period of the franchise/management agreement, which typically ranges from 10 to 20 years. Otherwise, the related principal is due and payable to the Company. In certain instances, the Company may earn interest on unpaid franchisee development advances. Such interest was not significant during 2014, 2013 or 2012. Development advances recorded on the Consolidated Balance Sheets amounted to $94 million and $97 million as of December 31, 2014 and 2013, respectively and are classified within the other non-current assets line item on the Consolidated Balance Sheets. During 2014, 2013 and 2012, the Company recorded $9 million, $7 million and $4 million, respectively, related to the forgiveness of these advances. Such amounts are recorded as a reduction of franchise fees on the Consolidated Statements of Income. In addition, during 2014, the Company received $6 million for the repayment of development advances which are recorded in investing other, net on the Consolidated Statement of Cash Flows. The Company recorded less than $1 million during each of 2014 and 2013, and $2 million during 2012 of bad debt expenses related to development advances that were due and payable within its lodging business. Such expense is recorded within operating expenses on the Consolidated Statements of Income.

	(*)	The valuation allowance of $57 million at December 31, 2014 relates to foreign tax credits, net operating loss carryforwards and certain deferred tax assets of $34 million, $19 million and $4 million, respectively. The valuation allowance of $26 million at December 31, 2013 relates to net operating loss carryforwards and certain deferred tax assets of $22 million and $4 million, respectively. The valuation allowance will be reduced when and if the Company determines it is more likely than not that the related deferred income tax assets will be realized.
	As of December 31, 2014, the Company’s net operating loss carryforwards primarily relate to state net operating losses which are due to expire at various dates, but no later than 2034. As of December 31, 2014, the Company had $86 million of foreign tax credits. The foreign tax credits primarily expire between 2017 and 2024.
	No provision has been made for U.S. federal deferred income taxes on $760 million of accumulated and undistributed earnings of certain foreign subsidiaries as of December 31, 2014 since it is the present intention of management to reinvest the undistributed earnings indefinitely in those foreign operations. The determination of the amount of unrecognized U.S. federal deferred income tax liability for unremitted earnings is not practicable. These earnings could become subject to additional taxes if remitted as dividends; the resulting U.S. income tax liabilities could be offset, in whole or in part, by credits allowable for taxes paid to foreign jurisdictions.
	The Company’s effective income tax rate differs from the U.S. federal statutory rate as follows for the year ended December 31:
		2014		2013	2012
	Federal statutory rate	35.00%		35.00%	35.00%
	State and local income taxes, net of federal tax benefits	3		3.7	2.8
	Taxes on foreign operations at rates different than U.S. federal statutory rates	-1.9		-2.3	-0.7
	Taxes on foreign income, net of tax credits	-4.6		-1.4	-1.3
	Valuation allowance	4		0.1	-0.5
	Other	1.9		1.5	1.2
		37.40%		36.60%	36.50%
	The Company’s effective tax rate increased from 36.6% in 2013 to 37.4% in 2014 primarily due to the lack of a tax benefit from the loss on the sale of its U.K.-based camping business.
	The following table summarizes the activity related to the Company’s unrecognized tax benefits:
	Amount
Balance as of December 31, 2011	$	29

Increases related to tax positions taken during the current period	3

The gross amount of the unrecognized tax benefits as of December 31, 2014, 2013 and 2012 that, if recognized, would affect the Company’s effective tax rate was $35 million, $36 million and $36 million, respectively. The Company recorded both accrued interest and penalties related to unrecognized tax benefits as a component of provision for income taxes on the Consolidated Statements of Income. The Company also accrued potential penalties and interest of $4 million, $2 million and $2 million related to these unrecognized tax benefits during 2014, 2013 and 2012, respectively. As of December 31, 2014, 2013 and 2012, the Company had recorded a liability for potential penalties of $4 million, $3 million and $3 million, respectively, and interest of $5 million, $4 million and $4 million, respectively, as a component of accrued expenses and other current liabilities and other non-current liabilities on the Consolidated Balance Sheets. The Company does not expect the unrecognized tax benefits to change significantly over the next 12 months.
The Company files U.S., state and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2011 through 2014 tax years generally remain subject to examination by federal tax authorities. The 2008 through 2014 tax years generally remain subject to examination by many state tax authorities. In significant foreign jurisdictions, the 2006 through 2014 tax years generally remain subject to examination by their respective tax authorities. The statute of limitations is scheduled to expire within 12 months of the reporting date in certain taxing jurisdictions and the Company believes that it is reasonably possible that the total amount of its unrecognized tax benefits could decrease by $10 million to $13 million.
The Company made cash income tax payments, net of refunds, of $249 million, $175 million and $134 million during 2014, 2013 and 2012, respectively. Such payments exclude income tax related payments made to or refunded by former Parent.

	Principal payments that are contractually due on the Company’s vacation ownership contract receivables during the next 12 months are classified as current on the Consolidated Balance Sheets. Principal payments due on the Company’s vacation ownership contract receivables during each of the five years subsequent to December 31, 2014 and thereafter are as follows:
		Securitized			Non -		Total
					Securitized

	Thereafter	1,160			343		1,503
		$	2,512		$	760	$	3,272
	During 2014, 2013 and 2012, the Company’s securitized vacation ownership contract receivables generated interest income of $300 million, $297 million and $306 million, respectively.
	During 2014, 2013 and 2012, the Company originated vacation ownership contract receivables of $1,013 million, $1,064 million and $1,074 million, respectively, and received principal collections of $792 million, $809 million and $771 million, respectively. The weighted average interest rate on outstanding vacation ownership contract receivables was 13.6%, 13.5% and 13.4% as of December 31, 2014, 2013 and 2012, respectively.
	The activity in the allowance for loan losses on vacation ownership contract receivables was as follows:
		Amount
	Allowance for loan losses as of December 31, 2011	$	394
	Provision for loan losses	409
	Contract receivables written off, net	(306		)

	Allowance for loan losses as of December 31, 2014	$	581
	Credit Quality for Financed Receivables and the Allowance for Credit Losses
	The basis of the differentiation within the identified class of financed VOI contract receivable is the consumer’s FICO score. A FICO score is a branded version of a consumer credit score widely used within the U.S. by the largest banks and lending institutions. FICO scores range from 300 – 850 and are calculated based on information obtained from one or more of the three major U.S. credit reporting agencies that compile and report on a consumer’s credit history. The Company updates its records for all active VOI contract receivables with a balance due on a rolling monthly basis so as to ensure that all VOI contract receivables are scored at least every six months. The Company groups all VOI contract receivables into five different categories: FICO scores ranging from 700 to 850, 600 to 699, Below 600, No Score (primarily comprised of consumers for whom a score is not readily available, including consumers declining access to FICO scores and non U.S. residents) and Asia Pacific (comprised of receivables in the Company’s Wyndham Vacation Resort Asia Pacific business for which scores are not readily available).
	The following table details an aged analysis of financing receivables using the most recently updated FICO scores (based on the policy described above):
		As of December 31, 2014
		700+			600-699		<600		No Score		Asia Pacific		Total
	Current	$	1,556		$	1,028	$	191	$	115	$	261	$	3,151

	61 - 90 days	7			13		11		2		1		34
	91 - 120 days	5			10		11		2		1		29
	Total	$	1,580		$	1,074	$	229	$	123	$	266	$	3,272
		As of December 31, 2013
		700+			600-699		<600		No Score		Asia Pacific		Total
	Current	$	1,515		$	1,060	$	224	$	108	$	280	$	3,187

	Total	$	1,537		$	1,108	$	270	$	117	$	287	$	3,319
	The Company ceases to accrue interest on VOI contract receivables once the contract has remained delinquent for greater than 90 days. At greater than 120 days, the VOI contract receivable is written off to the allowance for loan losses. In accordance with its policy, the Company assesses the allowance for loan losses using a static pool methodology and thus does not assess individual loans for impairment separate from the pool.

	(b)	Represents inventory that the Company expects to sell within the next 12 months.
	During 2014, the Company transferred $65 million from property and equipment to VOI inventory. In addition, the Company accrued $58 million for inventory purchases of which $46 million is included in other non-current liabilities and $12 million is included in accrued expenses and other current liabilities as of December 31, 2014.
	Inventory Sale Transaction
	During 2013, the Company sold real property located in Las Vegas, Nevada and Avon, Colorado, to a third-party developer, consisting of $123 million of vacation ownership inventory and $3 million of property and equipment. Total consideration was $126 million, of which $96 million was cash and $30 million was a note receivable. The Company recognized no gain or loss on these transactions.
	In accordance with the agreements with the third party developer, the Company has conditional rights and a conditional obligation to repurchase the completed properties from the developer subject to the properties conforming to the Company’s vacation ownership resort standards and provided that the third-party developer has not sold the properties to another party (see Note 17 - Commitments and Contingencies for more detailed information). Under the sale of real estate accounting guidance, the conditional rights and obligation of the Company constitute continuing involvement and thus the Company was unable to account for these transactions as a sale. The properties were sold to VIEs for which the Company is not the primary beneficiary as the Company does not control the entity’s development activities and cannot prevent the entities from selling the properties to other parties. Accordingly, the Company does not consolidate the VIEs.
	As of December 31, 2013, the Company had an outstanding obligation of $129 million, of which $47 million was recorded in accrued expenses and other current liabilities and $82 million was recorded in other non-current liabilities, and a note receivable of $30 million, which was recorded within other current assets on the Consolidated Balance Sheet. Interest on the note receivable accrued at 3% per annum. The $96 million of cash consideration received is included in (repayments of)/proceeds from vacation ownership inventory arrangements in the financing section on the Consolidated Statement of Cash Flows for the year ended December 31, 2013.
	During 2014, the Company reacquired a portion of the real property located in Las Vegas, Nevada from the third-party developer for $30 million in exchange for cancellation of the $30 million note receivable. In addition, the Company received $1 million of accrued interest on such note. The Company recognized no gain or loss on this transaction. In addition, during the fourth quarter of 2014, the Company paid $59 million to the third-party developer, of which $36 million was for vacation ownership inventory located in Las Vegas, Nevada and Avon, Colorado, $15 million was for its obligation under the vacation ownership inventory arrangements and $8 million was for accrued interest. The $15 million reduction in its obligation is included in (repayments of)/proceeds from vacation ownership inventory arrangements in the financing section on the Consolidated Statement of Cash Flows for the year ended December 31, 2014. The Company had an outstanding obligation of $81 million as of December 31, 2014, of which $7 million was recorded in accrued expenses and other current liabilities and $74 million was recorded in other non-current liabilities on the Consolidated Balance Sheet (see Note 17 - Commitments and Contingencies for more detailed information).

	Sierra Timeshare 2014-1 Receivables Funding, LLC. During March 2014, the Company closed a series of term notes payable, Sierra Timeshare 2014-1 Receivables Funding LLC, with an initial principal amount of $425 million, which are secured by vacation ownership contract receivables and bear interest at a weighted average coupon rate of 2.15%. The advance rate for this transaction was 88%. As of December 31, 2014, the Company had $274 million of outstanding borrowings under these term notes.
	Sierra Timeshare 2014-2 Receivables Funding, LLC.

The advance rate for this transaction was 91%. As of December 31, 2014, the Company had $278 million of outstanding borrowings under these term notes.
	Premium Yield Facility 2014-A, LLC. During October 2014, the Company closed a securitization facility, Premium Yield Facility 2014-A, LLC, in the initial principal amount of $204 million, utilizing previously non-securitized vacation ownership contract receivables. The advance rate for this transaction was 58%. These borrowings bear interest at a coupon rate of 3.00% and are secured by vacation ownership contract receivables. As of December 31, 2014, the Company has $186 million of outstanding borrowings under this facility.
	Sierra Timeshare 2014-3 Receivables Funding, LLC. During November 2014, the Company closed a series of term notes payable, Sierra Timeshare 2014-3 Receivables Funding LLC, with an initial principal amount of $325 million, which are secured by vacation ownership contract receivables and bear interest at a weighted average coupon rate of 2.41%. The advance rate for this transaction was 88.5%. As of December 31, 2014, the Company had $302 million of outstanding borrowings under these term notes.
	As of December 31, 2014, the Company had $922 million of outstanding borrowings under term notes entered into prior to December 31, 2013.
	The Company’s securitized term notes include fixed and floating rate term notes for which the weighted average interest rate was 3.7%, 4.2% and 4.9% during 2014, 2013 and 2012, respectively.
	Sierra Timeshare Conduit Receivables Funding II, LLC. During August 2014, the Company renewed its securitized timeshare receivables conduit facility for a two-year period through August 2016. The facility has a total capacity of $650 million and bears interest at variable rates based on commercial paper rates and LIBOR rates plus a spread. The bank conduit facility had a weighted average interest rate of 3.4%, 3.9% and 3.8% during 2014, 2013 and 2012, respectively.
	As of December 31, 2014, the Company’s securitized vacation ownership debt of $2,165 million is collateralized by $2,629 million of underlying gross vacation ownership contract receivables and related assets. Additional usage of the capacity of the Company’s bank conduit facility is subject to the Company’s ability to provide additional assets to collateralize such facility. The combined weighted average interest rate on the Company’s total securitized vacation ownership debt was 3.7%, 4.2% and 4.8% during 2014, 2013 and 2012, respectively.
	Long-Term Debt
	Revolving Credit Facility. During May 2013, the Company replaced its $1.0 billion revolving credit facility with a $1.5 billion five-year revolving credit facility that expires on July 15, 2018. This facility is subject to a fee of 20 basis points based on total capacity and bears interest at LIBOR plus 130 basis points on outstanding borrowings. The facility fee and interest rate are dependent on the Company’s credit ratings. The available capacity of the facility also supports the Company’s commercial paper programs.
	Commercial Paper. The Company maintains U.S. and European commercial paper programs with a total capacity of $750 million and $500 million, respectively. The maturities of U.S. and European commercial paper notes will vary, but may not exceed 366 days and 364 days, respectively, from the date of issue. As of December 31, 2014, the Company had outstanding borrowings of $189 million at a weighted average rate of 0.89%, all of which was under its U.S. commercial paper program. As of December 31, 2013, the Company had $210 million of outstanding borrowings at a weighted average interest rate of 0.74% under its commercial paper programs. The Company considers outstanding borrowings under its commercial paper programs to be a reduction of available capacity on its revolving credit facility.
The commercial paper notes are sold at a discount from par or will bear interest at a negotiated rate. While outstanding commercial paper borrowings generally have short-term maturities, the Company classifies the outstanding borrowings as long-term debt based on its intent and ability to refinance the outstanding borrowings on a long-term basis with its revolving credit facility.
As of December 31, 2014, the Company had $2,423 million of outstanding senior unsecured notes issued prior to December 31, 2013. Interest is payable semi-annually in arrears on the notes. The notes are redeemable at the Company’s option at any time, in whole or in part, at the stated redemption prices plus accrued interest through the redemption dates. These notes rank equally in right of payment with all of the Company’s other senior unsecured indebtedness.
Vacation Rental Capital Leases. The Company leases vacation homes located in European holiday parks as part of its vacation exchange and rentals business. The majority of these leases are recorded as capital lease obligations with corresponding assets classified within property and equipment, net on the Consolidated Balance Sheets. Such capital lease obligations had a weighted average interest rate of 4.5% during each of 2014, 2013 and 2012.
Capital Lease. During the first quarter of 2013, the Company extended the lease on its Corporate headquarters. As a result of this extension, the Company classified the lease as a capital lease and recorded a capital lease obligation of $85 million with a corresponding capital lease asset which was recorded net of deferred rent. Such transaction was non-cash and as such, is excluded from both investing and financing activities within the Company’s Consolidated Statement of Cash Flows. Such capital lease had an interest rate of 4.5% during both 2014 and 2013.
Other. During January 2013, the Company entered into an agreement with a third-party partner whereby the partner acquired Midtown 45 through an SPE. The SPE financed the purchase with a $115 million four-year mortgage note, provided by related parties of such partner. The note accrues interest at 4.5% and the principal and interest are payable semi-annually, commencing on July 24, 2013. In addition, $9 million of mandatorily redeemable equity of the SPE was classified as long-term debt. As of December 31, 2014, $71 million of the four-year mortgage note and $6 million of mandatorily redeemable equity were outstanding. As of December 31, 2013, $99 million of the four-year mortgage note and $8 million of mandatorily redeemable equity were outstanding. See Note 14 - Variable Interest Entities for more detailed information.
Fair Value Hedges. The Company has pay-variable/receive-fixed interest rate swap agreements on its 3.90% and 4.25% senior unsecured notes with notional amounts of $400 million and $100 million, respectively. The fixed interest rates on these notes were effectively modified to a variable LIBOR-based index. As of December 31, 2014, the variable interest rates on the notional portion of the 3.90% and 4.25% senior unsecured notes were 2.38% and 2.29%, respectively. The aggregate fair value of these interest rate swap agreements resulted in $18 million of assets and $12 million of liabilities as of December 31, 2014 and 2013, respectively. Such assets and liabilities are included in other non-current assets and in other non-current liabilities, respectively, on the Consolidated Balance Sheets.
3.50% Convertible Notes. During May 2009, the Company issued convertible notes (“Convertible Notes”) with face value of $230 million and bearing interest at a rate of 3.50%, for net proceeds of $224 million. The Company accounted for the conversion feature as a derivative instrument under the guidance for derivatives and bifurcated such conversion feature from the Convertible Notes for accounting purposes. The fair value of the Bifurcated Conversion Feature on the issuance date of the Convertible Notes was recorded as original issue discount for purposes of accounting for the debt component of the Convertible Notes. Therefore, interest expense greater than the coupon rate of 3.50% was recognized by the Company primarily resulting from the accretion of the discounted carrying value of the Convertible Notes to their face amount over the term of the Convertible Notes. Concurrent with the issuance of the Convertible Notes, the Company entered into convertible note hedge and warrant transactions with certain counterparties. During 2012, the Company repaid upon maturity, its remaining Convertible Notes with a carrying value of $45 million ($12 million for the Convertible Notes and $33 million for a related Bifurcated Conversion Feature). Concurrent with the repayment, the Company settled the Call Options for proceeds of $33 million. As a result of these transactions, the Company made a net payment of $12 million.
Early Extinguishment of Debt
During 2013, the Company repurchased a portion of its 5.75% and 7.375% senior unsecured notes totaling $446 million through tender offers, repurchased $42 million of its 6.00% senior unsecured notes on the open market and executed a redemption option for the remaining $43 million outstanding on its 9.875% senior unsecured notes. As a result, during 2013, the Company repurchased a total of $531 million of its outstanding senior unsecured notes and incurred expenses of $111 million which is included within early extinguishment of debt on the Consolidated Statement of Income.
During 2012, the Company repurchased $443 million of its 6.00% and $207 million of its 9.875% senior unsecured notes totaling $650 million through tender offers. In connection with these tender offers, the Company incurred a loss of $108 million, which is included within early extinguishment of debt on the Consolidated Statement of Income.
Interest Expense
The Company incurred non-securitized interest expense of $113 million during 2014. Such amount consisted primarily of interest on long-term debt, partially offset by $6 million of capitalized interest and $2 million of gains resulting from the ineffectiveness of the fair value hedges. Such amounts are included within interest expense on the Consolidated Statement of Income. Cash paid related to interest on the Company’s non-securitized debt was $119 million.
The Company incurred non-securitized interest expense of $131 million during 2013. Such amount consisted primarily of interest on long-term debt, partially offset by $5 million of capitalized interest and is recorded within interest expense on the Consolidated Statement of Income. Cash paid related to interest on the Company’s non-securitized debt was $127 million.
The Company incurred non-securitized interest expense of $132 million during 2012. Such amount consisted primarily of interest on long-term debt, partially offset by $5 million of capitalized interest and is recorded within interest expense on the Consolidated Statement of Income. Cash paid related to interest on the Company’s non-securitized debt was $120 million.
Interest expense incurred in connection with the Company’s securitized vacation ownership debt was $71 million, $78 million and $90 million during 2014, 2013 and 2012, respectively, and is recorded within consumer financing interest on the Consolidated Statements of Income. Cash paid related to such interest was $53 million, $61 million and $73 million during 2014, 2013 and 2012, respectively.

Variable Interest Entity, Classification of Carrying Amount, Assets and Liabilities, Net [Abstract]
Variable Interest Entities	Variable Interest Entities
	The Company pools qualifying vacation ownership contract receivables and sells them to bankruptcy-remote entities. Vacation ownership contract receivables qualify for securitization based primarily on the credit strength of the VOI purchaser to whom financing has been extended. Vacation ownership contract receivables are securitized through bankruptcy-remote SPEs that are consolidated within the Consolidated Financial Statements. As a result, the Company does not recognize gains or losses resulting from these securitizations at the time of sale to the SPEs. Interest income is recognized when earned over the contractual life of the vacation ownership contract receivables. The Company services the securitized vacation ownership contract receivables pursuant to servicing agreements negotiated on an arms-length basis based on market conditions. The activities of these SPEs are limited to (i) purchasing vacation ownership contract receivables from the Company’s vacation ownership subsidiaries, (ii) issuing debt securities and/or borrowing under a conduit facility to fund such purchases and (iii) entering into derivatives to hedge interest rate exposure. The bankruptcy-remote SPEs are legally separate from the Company. The receivables held by the bankruptcy-remote SPEs are not available to creditors of the Company and legally are not assets of the Company. Additionally, the creditors of these SPEs have no recourse to the Company for principal and interest.
	The assets and liabilities of these vacation ownership SPEs are as follows:
		December 31,			December 31,
		2014			2013
	Securitized contract receivables, gross (a)	$	2,512		$	2,204

	(c)	Included in trade receivables, net on the Consolidated Balance Sheets.
	(d)	Includes interest rate derivative contracts and related assets; included in other non-current assets on the Consolidated Balance Sheets.
	(e)	Excludes deferred financing costs of $30 million and $28 million as of December 31, 2014 and 2013, respectively, related to securitized debt.
	(f)	Included in current ($214 million and $184 million as of December 31, 2014 and 2013, respectively) and long-term ($1,951 million and $1,726 million as of December 31, 2014 and 2013, respectively) securitized vacation ownership debt on the Consolidated Balance Sheets.
	(g)	Primarily includes accrued interest on securitized debt ($1 million and $2 million as of December 31, 2014 and 2013, respectively) which is included in accrued expenses and other current liabilities on the Consolidated Balance Sheets.
	In addition, the Company has vacation ownership contract receivables that have not been securitized through bankruptcy-remote SPEs. Such gross receivables were $760 million and $1,115 million as of December 31, 2014 and 2013, respectively. A summary of total vacation ownership receivables and other securitized assets, net of securitized liabilities and the allowance for loan losses, is as follows:
		December 31,			December 31,

	During January 2013, the Company entered into an agreement with a third-party partner whereby the partner acquired Midtown 45 through an SPE. The Company is managing and operating the property for rental purposes while the Company converts it into VOI inventory. The SPE financed the acquisition and planned renovations with a $115 million four-year mortgage note and $9 million of mandatorily redeemable equity provided by related parties of such partner. At the time of the agreement, the Company committed to purchase such VOI inventory from the SPE over a four-year period in the amount of $146 million, of which $124 million will be used to repay the four-year mortgage note and the mandatorily redeemable equity of the SPE. The Company is considered to be the primary beneficiary of the SPE and therefore, the Company consolidated the SPE within its financial statements.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value
	The following table presents information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair values. Financial assets and liabilities carried at fair value are classified and disclosed in one of the following three categories:
	Level 1: Quoted prices for identical instruments in active markets.
	Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value driver is observable.
	Level 3: Unobservable inputs used when little or no market data is available.
	In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement falls has been determined based on the lowest level input (closest to Level 3) that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
	The following table summarizes information regarding assets and liabilities that are measured at fair value on a recurring basis:
		As of						As of
		December 31, 2014						December 31, 2013

	(b)	Included in other non-current assets on the Consolidated Balance Sheets.
	(c)	Included in accrued expenses and other current liabilities ($7 million and $2 million as of December 31, 2014 and 2013, respectively) and other non-current liabilities ($13 million as of December 31, 2013) on the Consolidated Balance Sheets; carrying value is equal to estimated fair value.
	(d)	The $4 million liability as of December 31, 2014, represents interest rate swap locks for an anticipated 2015 transaction.
	The Company’s derivative instruments primarily consist of pay-fixed/receive-variable interest rate swaps, pay-variable/receive-fixed interest rate swaps, interest rate caps, foreign exchange forward contracts and foreign exchange average rate forward contracts (see Note 16 – Financial Instruments for more detail). For assets and liabilities that are measured using quoted prices in active markets, the fair value is the published market price per unit multiplied by the number of units held without consideration of transaction costs. Assets and liabilities that are measured using other significant observable inputs are valued by reference to similar assets and liabilities. For these items, a significant portion of fair value is derived by reference to quoted prices of similar assets and liabilities in active markets. For assets and liabilities that are measured using significant unobservable inputs, fair value is primarily derived using a fair value model, such as a discounted cash flow model.
	The fair value of financial instruments is generally determined by reference to market values resulting from trading on a national securities exchange or in an over-the-counter market. In cases where quoted market prices are not available, fair value is based on estimates using present value or other valuation techniques, as appropriate. The carrying amounts of cash and cash equivalents, restricted cash, trade receivables, accounts payable and accrued expenses and other current liabilities approximate fair value due to the short-term maturities of these assets and liabilities. The carrying amounts and estimated fair values of all other financial instruments are as follows:
		December 31, 2014				December 31, 2013
		Carrying		Estimated Fair Value		Carrying		Estimated Fair Value
		Amount				Amount
	Assets
	Vacation ownership contract receivables, net	$	2,691	$	3,284	$	2,753	$	3,326
	Debt
	Total debt	5,053		5,140		4,841		4,928
	The Company estimates the fair value of its vacation ownership contract receivables using a discounted cash flow model which it believes is comparable to the model that an independent third-party would use in the current market. The model uses Level 3 inputs consisting of default rates, prepayment rates, coupon rates and loan terms for the contract receivables portfolio as key drivers of risk and relative value that, when applied in combination with pricing parameters, determines the fair value of the underlying contract receivables.
	The Company estimates the fair value of its securitized vacation ownership debt by obtaining Level 2 inputs comprised of indicative bids from investment banks that actively issue and facilitate the secondary market for timeshare securities. The Company estimates the fair value of its other long-term debt, excluding capital leases, using Level 2 inputs based on indicative bids from investment banks and determines the fair value of its senior notes using quoted market prices (such senior notes are not actively traded).

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	Financial Instruments
	The designation of a derivative instrument as a hedge and its ability to meet the hedge accounting criteria determine how the change in fair value of the derivative instrument will be reflected in the Consolidated Financial Statements. A derivative qualifies for hedge accounting if, at inception, the derivative is expected to be highly effective in offsetting the underlying hedged cash flows or fair value and the hedge documentation standards are fulfilled at the time the Company enters into the derivative contract. A hedge is designated as a cash flow hedge based on the exposure being hedged. The asset or liability value of the derivative will change in tandem with its fair value. Changes in fair value, for the effective portion of qualifying hedges, are recorded in AOCI. The derivative’s gain or loss is released from AOCI to match the timing of the underlying hedged cash flows effect on earnings.
	The Company reviews the effectiveness of its hedging instruments on an ongoing basis, recognizes current period hedge ineffectiveness immediately in earnings and discontinues hedge accounting for any hedge that it no longer considers to be highly effective. The Company recognizes changes in fair value for derivatives not designated as hedges or those not qualifying for hedge accounting in current period earnings. Upon termination of cash flow hedges, the Company releases gains and losses from AOCI based on the timing of the underlying cash flows, unless the termination results from the failure of the intended transaction to occur in the expected time frame. Such untimely transactions require the Company to immediately recognize in earnings gains and losses previously recorded in AOCI.
	Changes in interest rates and foreign exchange rates expose the Company to market risk. The Company also uses cash flow hedges as part of its overall strategy to manage its exposure to market risks associated with fluctuations in interest rates and foreign currency exchange rates. As a matter of policy, the Company only enters into transactions that it believes will be highly effective at offsetting the underlying risk and it does not use derivatives for trading or speculative purposes.
	The Company uses the following derivative instruments to mitigate its foreign currency exchange rate and interest rate risks:
	Foreign Currency Risk
	The Company has foreign currency rate exposure to exchange rate fluctuations worldwide with particular exposure to the British pound, Euro, Canadian and Australian dollar. The Company uses freestanding foreign currency forward contracts to manage a portion of its exposure to changes in foreign currency exchange rates associated with its foreign currency denominated receivables and forecasted earnings of foreign subsidiaries. Additionally, the Company uses foreign currency forward contracts designated as cash flow hedges to manage a portion of its exposure to changes in forecasted foreign currency denominated vendor payments. The amount of gains or losses relating to contracts designated as cash flow hedges that the Company expects to reclassify from AOCI to earnings over the next 12 months is not material.
	Interest Rate Risk
	A portion of the debt used to finance the Company’s operations is exposed to interest rate fluctuations. The Company uses various hedging strategies and derivative financial instruments to create a desired mix of fixed and floating rate assets and liabilities. Derivative instruments currently used in these hedging strategies include swaps and interest rate caps. The derivatives used to manage the risk associated with the Company’s floating rate debt include freestanding derivatives and derivatives designated as cash flow hedges. The Company also uses swaps to convert specific fixed-rate debt into variable-rate debt (i.e., fair value hedges) to manage the overall interest cost. For relationships designated as fair value hedges, changes in fair value of the derivatives are recorded in income with offsetting adjustments to the carrying amount of the hedged debt. The amount of gains or losses that the Company expects to reclassify from AOCI to earnings during the next 12 months is not material.

	(a)	Included within operating expenses on the Consolidated Statements of Income, which is primarily offset by changes in the value of the underlying assets and liabilities.
	(b)	Included within consumer financing interest expense on the Consolidated Statements of Income.
	Credit Risk and Exposure
	The Company is exposed to counterparty credit risk in the event of nonperformance by counterparties to various agreements and sales transactions. The Company manages such risk by evaluating the financial position and creditworthiness of such counterparties and by requiring collateral in instances in which financing is provided. The Company mitigates counterparty credit risk associated with its derivative contracts by monitoring the amounts at risk with each counterparty to such contracts, periodically evaluating counterparty creditworthiness and financial position, and where possible, dispersing its risk among multiple counterparties.
	As of December 31, 2014, there were no significant concentrations of credit risk with any individual counterparty or groups of counterparties. However, approximately 19% of the Company’s outstanding vacation ownership contract receivables portfolio relates to customers who reside in California. With the exception of the financing provided to customers of its vacation ownership businesses, the Company does not normally require collateral or other security to support credit sales.
	Market Risk
	The Company is subject to risks relating to the geographic concentrations of (i) areas in which the Company is currently developing and selling vacation ownership properties, (ii) sales offices in certain vacation areas and (iii) customers of the Company’s vacation ownership business, which in each case, may result in the Company’s results of operations being more sensitive to local and regional economic conditions and other factors, including competition, natural disasters and economic downturns, than the Company’s results of operations would be, absent such geographic concentrations. Local and regional economic conditions and other factors may differ materially from prevailing conditions in other parts of the world. Florida, California and Nevada are examples of areas with concentrations of sales offices. For the year ended December 31, 2014, approximately 14%, 11% and 11% of the Company’s VOI sales revenues were generated in sales offices located in Florida, California and Nevada, respectively.
	Included within the Consolidated Statements of Income is approximately 14%, 10% and 11% of net revenues generated from transactions in the state of Florida during 2014, 2013 and 2012, respectively, and 12% of net revenues generated from transactions in the state of California in 2014.

	COMMITMENTS
	Leases
	The Company is committed to making rental payments under noncancelable operating leases covering various facilities and equipment. Future minimum lease payments required under noncancelable operating leases as of December 31, 2014 are as follows:
		Noncancelable
		Operating
		Leases
	2015	$	94
	2016	66
	2017	55
	2018	48
	2019	41
	Thereafter	200
		$	504
	During 2014, 2013 and 2012, the Company incurred total rental expense of $83 million, $80 million and $80 million, respectively.
	Purchase Commitments
	In the normal course of business, the Company makes various commitments to purchase goods or services from specific suppliers, including those related to vacation ownership resort development and other capital expenditures. Purchase commitments made by the Company as of December 31, 2014 aggregated $361 million. Approximately $71 million and $65 million of the commitments relate to information technology and the development of vacation ownership properties, respectively.
	Letters of Credit
	As of December 31, 2014, the Company had $69 million of irrevocable standby letters of credit outstanding, of which $2 million were under its revolving credit facility. As of December 31, 2013, the Company had $55 million of irrevocable standby letters of credit outstanding, of which $9 million were under its revolving credit facility. Such letters of credit issued during 2014 and 2013 primarily supported the securitization of vacation ownership contract receivables fundings, certain insurance policies and development activity at the Company’s vacation ownership business.
	Surety Bonds
	Some of the Company’s vacation ownership sales and developments are supported by surety bonds provided by affiliates of certain insurance companies in order to meet regulatory requirements of certain states. In the ordinary course of the Company’s business, it has assembled commitments from 13 surety providers in the amount of $1.3 billion, of which the Company had $406 million outstanding as of December 31, 2014. The availability, terms and conditions and pricing of bonding capacity are dependent on, among other things, continued financial strength and stability of the insurance company affiliates providing the bonding capacity, general availability of such capacity and the Company’s corporate credit rating. If the bonding capacity is unavailable or, alternatively, the terms and conditions and pricing of the bonding capacity are unacceptable to the Company, the cost of development of the Company’s vacation ownership units could be negatively impacted.
	LITIGATION
	The Company is involved in claims, legal and regulatory proceedings and governmental inquiries related to the Company’s business.
	Wyndham Worldwide Corporation Litigation
	The Company is involved in claims, legal and regulatory proceedings and governmental inquiries arising in the ordinary course of its business including but not limited to: for its lodging business-breach of contract, fraud and bad faith claims between franchisors and franchisees in connection with franchise agreements and with owners in connection with management contracts, negligence, breach of contract, fraud, employment, consumer protection and other statutory claims asserted in connection with alleged acts or occurrences at owned, franchised or managed properties or in relation to guest reservations and bookings; for its vacation exchange and rentals business-breach of contract, fraud and bad faith claims by affiliates and customers in connection with their respective agreements, negligence, breach of contract, fraud, consumer protection and other statutory claims asserted by members and guests for alleged injuries sustained at affiliated resorts and vacation rental properties and consumer protection and other statutory claims asserted by consumers; for its vacation ownership business-breach of contract, bad faith, conflict of interest, fraud, consumer protection and other statutory claims by property owners’ associations, owners and prospective owners in connection with the sale or use of VOIs or land, or the management of vacation ownership resorts, construction defect claims relating to vacation ownership units or resorts, and negligence, breach of contract, fraud, consumer protection and other statutory claims by guests for alleged injuries sustained at vacation ownership units or resorts; and for each of its businesses, bankruptcy proceedings involving efforts to collect receivables from a debtor in bankruptcy, employment matters which may include claims of retaliation, discrimination, harassment and wage and hour claims, claims of infringement upon third parties’ intellectual property rights, claims relating to information security, privacy and consumer protection, tax claims and environmental claims.
	On June 26, 2012, the U.S. Federal Trade Commission (“FTC”) filed a lawsuit in Federal District Court for the District of Arizona against the Company and its subsidiaries, Wyndham Hotel Group, LLC (“WHG”), Wyndham Hotels & Resorts Inc. (“WHR”) and Wyndham Hotel Management Inc. (“WHM”), alleging unfairness and deception-based violations of Section 5 of the FTC Act in connection with three prior data breach incidents involving a group of Wyndham brand hotels. The Company, WHG, WHR and WHM dispute the allegations in the lawsuit and are defending this lawsuit vigorously. The Company does not believe that the data breach incidents were material, nor does it expect that the outcome of the FTC litigation will have a material effect on the Company’s results of operations, financial position or cash flows. On March 26, 2013, the Company’s, WHG’s, WHR’s and WHM’s motion to transfer venue of the lawsuit from Arizona to the Federal District Court for the District of New Jersey was granted. WHR’s motion to dismiss the lawsuit was denied on April 7, 2014. The Court granted WHR’s motion to certify its order denying WHR’s motion to dismiss for interlocutory appeal on June 23, 2014. The motion to dismiss filed by the Company, WHG and WHM was denied on June 23, 2014. On July 29, 2014, the Third Circuit Court of Appeals granted WHR’s request to file an interlocutory appeal of the District Court’s denial of its motion to dismiss. WHR filed its brief in support of its interlocutory appeal on October 6, 2014. The FTC filed its opposition brief on November 5, 2014, and WHR filed its reply brief on December 8, 2014. The Company is unable at this time to estimate any loss or range of reasonably possible loss.
	The Company records an accrual for legal contingencies when it determines, after consultation with outside counsel, that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In making such determinations, the Company evaluates, among other things, the degree of probability of an unfavorable outcome and, when it is probable that a liability has been incurred, the Company’s ability to make a reasonable estimate of loss. The Company reviews these accruals each reporting period and makes revisions based on changes in facts and circumstances including changes to its strategy in dealing with these matters.
	The Company believes that it has adequately accrued for such matters with reserves of $24 million and $22 million as of December 31, 2014 and 2013, respectively. Such reserves are exclusive of matters relating to the Separation. For matters not requiring accrual, the Company believes that such matters will not have a material effect on its results of operations, financial position or cash flows based on information currently available. However, litigation is inherently unpredictable and, although the Company believes that its accruals are adequate and/or that it has valid defenses in these matters, unfavorable results could occur. As such, an adverse outcome from such proceedings for which claims are awarded in excess of the amounts accrued, if any, could be material to the Company with respect to earnings and/or cash flows in any given reporting period. As of December 31, 2014, the potential exposure resulting from adverse outcomes of such legal proceedings could, in the aggregate, range up to approximately $22 million in excess of recorded accruals. However, the Company does not believe that the impact of such litigation should result in a material liability to the Company in relation to its consolidated financial position or liquidity.
	Cendant Litigation
	Under the Separation agreement, the Company agreed to be responsible for 37.5% of certain of Cendant’s contingent and other corporate liabilities and associated costs, including certain contingent litigation. Since the Separation, Cendant settled the majority of the lawsuits pending on the date of the Separation. See also Note 23 - Separation Adjustments and Transactions with Former Parent and Subsidiaries regarding contingent litigation liabilities resulting from the Separation.
	GUARANTEES/INDEMNIFICATIONS
	Standard Guarantees/Indemnifications
	In the ordinary course of business, the Company enters into agreements that contain standard guarantees and indemnities whereby the Company indemnifies another party for specified breaches of or third-party claims relating to an underlying agreement. Such underlying agreements are typically entered into by one of the Company’s subsidiaries. The various underlying agreements generally govern purchases, sales or outsourcing of products or services, leases of real estate, licensing of software and/or development of vacation ownership properties, access to credit facilities, derivatives and issuances of debt securities. While a majority of these guarantees and indemnifications extend only for the duration of the underlying agreement, some survive the expiration of the agreement. The Company is not able to estimate the maximum potential amount of future payments to be made under these guarantees and indemnifications as the triggering events are not predictable. In certain cases, the Company maintains insurance coverage that may mitigate any potential payments.
	Other Guarantees/Indemnifications
	Lodging
	From time to time, the Company may enter into a hotel management agreement that provides the hotel owner with a guarantee of a certain level of profitability based upon various metrics. Under such an agreement, the Company would be required to compensate such hotel owner for any profitability shortfall over the life of the management agreement up to a specified aggregate amount. For certain agreements, the Company may be able to recapture all or a portion of the shortfall payments in the event that future operating results exceed targets. The terms of such guarantees generally range from 7 to 10 years and certain agreements may provide for early termination provisions under certain circumstances. As of December 31, 2014, the maximum potential amount of future payments that may be made under these guarantees was $136 million with a combined annual cap of $39 million. The Company had an additional guarantee of $30 million with a $3 million cap for 2014 with no annual cap thereafter.
	In connection with such performance guarantees, as of December 31, 2014, the Company maintained a liability of $32 million, of which $31 million was included in other non-current liabilities and $1 million was included in accrued expenses and other current liabilities on its Consolidated Balance Sheet. As of December 31, 2014, the Company also had a corresponding $39 million asset related to these guarantees, of which $35 million was included in other non-current assets and $4 million was included in other current assets on its Consolidated Balance Sheet. As of December 31, 2013, the Company maintained a liability of $45 million, of which $37 million was included in other non-current liabilities and $8 million was included in accrued expenses and other current liabilities on its Consolidated Balance Sheet. As of December 31, 2013, the Company also had a corresponding $43 million asset related to the guarantees, of which $39 million was included in other non-current assets and $4 million was included in other current assets on its Consolidated Balance Sheet. Such assets are being amortized on a straight-line basis over the life of the agreements. The amortization expense for the performance guarantees noted above was $4 million and $3 million for the years ended December 31, 2014 and 2013, respectively.
	For guarantees subject to recapture provisions, the Company had a receivable of $26 million and $24 million which was included in other non-current assets on the Company’s Consolidated Balance Sheets for the years ended December 31, 2014 and 2013, respectively. Such receivables were the result of payments made to date which are subject to recapture and which the Company believes will be recoverable from future operating performance.
	Vacation Ownership
	In the ordinary course of business, the Company’s vacation ownership business provides guarantees to certain owners’ associations for funds required to operate and maintain vacation ownership properties in excess of assessments collected from owners of the VOIs. The Company may be required to fund such excess as a result of unsold Company-owned VOIs or failure by owners to pay such assessments. In addition, from time to time, the Company will agree to reimburse certain owner associations up to 75% of their uncollected assessments. These guarantees extend for the duration of the underlying subsidy or similar agreement (which generally approximate one year and are renewable at the discretion of the Company on an annual basis). The maximum potential future payments that the Company could be required to make under these guarantees were approximately $328 million as of December 31, 2014. The Company would only be required to pay this maximum amount if none of the assessed owners paid their assessments. Any assessments collected from the owners of the VOIs would reduce the maximum potential amount of future payments to be made by the Company. Additionally, should the Company be required to fund the deficit through the payment of any owners’ assessments under these guarantees, the Company would be permitted access to the property for its own use and may use that property to engage in revenue-producing activities, such as rentals. During 2014, 2013 and 2012, the Company made payments related to these guarantees of $17 million, $18 million and $18 million, respectively. As of December 31, 2014 and 2013, the Company maintained a liability in connection with these guarantees of $25 million and $30 million, respectively, on its Consolidated Balance Sheets.
	The Company guarantees its vacation ownership subsidiary’s obligation to repurchase completed property in Las Vegas, Nevada from a third-party developer subject to the property meeting the Company’s vacation ownership resort standards and provided that the third-party developer has not sold the property to another party. The maximum potential future payments that the Company could be required to make under these commitments was $262 million as of December 31, 2014.
	The Company entered into a management agreement that provides a guarantee of a certain level of profitability based upon various metrics. As of December 31, 2014, the maximum potential amount of future payments that may be made under this guarantee was $10 million with an annual cap of $1 million.
	As part of WAAM Fee-for-Service, the Company may guarantee to reimburse the developer a certain payment or to purchase from the developer, inventory associated with the developer’s resort property for a percentage of the original sale price if certain future conditions exist. The maximum potential future payments that the Company could be required to make under these guarantees were approximately $49 million as of December 31, 2014. As of both December 31, 2014 and 2013, the Company had no recognized liabilities in connection with these guarantees.

	(a)	Primarily represents awards granted by the Company on February 27, 2014.
	(b)	Aggregate unrecognized compensation expense related to RSUs and SSARs was $83 million as of December 31, 2014, which is expected to be recognized over a weighted average period of 2.5 years.
	(c)	Approximately 1.9 million RSUs outstanding as of December 31, 2014 are expected to vest over time.
	(d)	Maximum aggregate unrecognized compensation expense was $20 million as of December 31, 2014.
	(e)	Approximately 0.5 million SSARs are exercisable as of December 31, 2014. The Company assumes that all unvested SSARs are expected to vest over time. SSARs outstanding as of December 31, 2014 had an intrinsic value of $33 million and have a weighted average remaining contractual life of 2.6 years.
	During 2014, 2013 and 2012, the Company granted incentive equity awards totaling $54 million, $54 million and $51 million, respectively, to the Company’s key employees and senior officers in the form of RSUs and SSARs. The 2014, 2013 and 2012 awards will vest ratably over a period of four years. In addition, during 2014, 2013 and 2012, the Company approved grants of incentive equity awards totaling $14 million, $14 million and $12 million respectively, to key employees and senior officers of the Company in the form of PSUs. These awards cliff vest on the third anniversary of the grant date, contingent upon the Company achieving certain performance metrics.
	The fair value of SSARs granted by the Company during 2014, 2013 and 2012 was estimated on the date of the grant using the Black-Scholes option-pricing model with the relevant weighted average assumptions outlined in the table below. Expected volatility is based on both historical and implied volatilities of the Company’s stock over the estimated expected life of the SSARs. The expected life represents the period of time the SSARs are expected to be outstanding and is based on historical experience given consideration to the contractual terms and vesting periods of the SSARs. The risk free interest rate is based on yields on U.S. Treasury strips with a maturity similar to the estimated expected life of the SSARs. The projected dividend yield was based on the Company’s anticipated annual dividend divided by the price of the Company’s stock on the date of the grant.

	The Company recorded stock-based compensation expense of $57 million, $53 million and $41 million during 2014, 2013 and 2012, respectively, related to the incentive equity awards granted to employees by the Company. The Company recognized a net tax benefit of $23 million, $21 million and $16 million during 2014, 2013 and 2012, respectively, for stock-based compensation arrangements on the Consolidated Statements of Income. During 2014, 2013 and 2012, the Company increased its pool of excess tax benefits available to absorb tax deficiencies (“APIC Pool”) by $34 million, $15 million and $33 million, respectively, due to the vesting of RSUs, PSUs and SSARs.

Segment Reporting [Abstract]
Segment Information	Segment Information
	The reportable segments presented below represent the Company’s operating segments for which separate financial information is available and which is utilized on a regular basis by its chief operating decision maker to assess performance and to allocate resources. In identifying its reportable segments, the Company also considers the nature of services provided by its operating segments. Management evaluates the operating results of each of its reportable segments based upon net revenues and “EBITDA”, which is defined as net income before depreciation and amortization, interest expense (excluding consumer financing interest), early extinguishment of debt, interest income (excluding consumer financing interest) and income taxes, each of which is presented on the Consolidated Statements of Income. The Company believes that EBITDA is a useful measure of performance for its industry segments which, when considered with GAAP measures, the Company believes gives a more complete understanding of its operating performance. The Company’s presentation of EBITDA may not be comparable to similarly-titled measures used by other companies.

During 2014, the Company reduced its liability with $5 million of cash payments and reversed $1 million of previously recorded contract termination costs.
	2012 Restructuring Plans
	During 2012, the Company committed to an organizational realignment initiative at its vacation exchange and rentals business, primarily focused on consolidating existing processes and optimizing its structure. Also during 2012, the Company implemented an organizational realignment initiative at its vacation ownership business, targeting the elimination of business function redundancies resulting from the Shell acquisition. During 2012, the Company incurred costs of $7 million and reduced its liability with cash payments of $1 million. During 2013, the Company (i) reduced its liability with $5 million of cash payments, (ii) recorded $2 million of additional facility-related expenses, (iii) increased its liability with $1 million of a non-cash adjustment associated with a facility closure and (iv) reversed $1 million of previously recorded personnel costs. During 2014, the Company reduced its liability with cash payments of $1 million. As of December 31, 2014, the Company had a liability of $2 million, which is expected to be paid in cash by January 2017. From the commencement of the 2012 restructuring plans through December 31, 2014, the Company has incurred a total of $8 million of expenses in connection with such plans.
	As of December 31, 2014, the Company had a remaining liability of $2 million related to its 2010 restructuring plan, all of which is facility-related.

	Loss on Sale
	During 2014, the Company sold its U.K.-based camping business at its vacation exchange and rentals business resulting in a $20 million loss. As a result of this transaction, the Company received $1 million of cash, net, reduced its net assets by $11 million, wrote-off $6 million of foreign currency translation adjustments and recorded a $4 million indemnification liability. Such loss is recorded within loss on sale and asset impairments on the Consolidated Statement of Income.
	Impairments
	During 2014, the Company recorded a $7 million non-cash impairment charge related to the write-down of an equity investment at its vacation exchange and rentals business which was the result of a reduction in the fair value of the entity in which the Company has a minority ownership position. In addition, the Company recorded an $8 million non-cash impairment charge at its lodging business related to the write-down of an investment in a joint venture, which was the result of the joint venture’s recurring losses and negative operating cash flows. Such amounts are recorded within loss on sale and asset impairments on the Consolidated Statement of Income.
	During 2013, the Company recorded $8 million of non-cash impairment charges at its lodging business primarily related to a partial write-down of its Hawthorn trademark due to lower than anticipated growth in the brand. Such amount is recorded within loss on sale and asset impairments on the Consolidated Statement of Income.
	During 2012, the Company recorded an $8 million non-cash impairment charge at its vacation exchange and rentals business resulting from the decision to rebrand the ResortQuest and Steamboat Resorts trade names to the Wyndham Vacation Rentals brand. Such amount is recorded within loss on sale and asset impairments on the Consolidated Statement of Income.

Separation Adjustments And Transactions With Former Parent And Subsidiaries	Separation Adjustments and Transactions with Former Parent and Subsidiaries
	Transfer of Cendant Corporate Liabilities and Issuance of Guarantees to Cendant and Affiliates
	Pursuant to the Separation and Distribution Agreement, upon the distribution of the Company’s common stock to Cendant shareholders, the Company entered into certain guarantee commitments with Cendant (pursuant to the assumption of certain liabilities and the obligation to indemnify Cendant and Realogy and travel distribution services (“Travelport”) for such liabilities) and guarantee commitments related to deferred compensation arrangements with each of Cendant and Realogy. These guarantee arrangements primarily relate to contingent litigation liabilities, contingent tax liabilities, and Cendant contingent and other corporate liabilities, of which the Company assumed and is responsible for 37.5% while Realogy is responsible for the remaining 62.5%. The remaining amount of liabilities which were assumed by the Company in connection with the Separation was $38 million and $39 million as of December 31, 2014 and 2013, respectively. These amounts were comprised of Cendant corporate liabilities which were recorded on the books of Cendant as well as additional liabilities which were established for guarantees issued at the date of Separation, related to unresolved contingent matters and others that could arise during the guarantee period. Regarding the guarantees, if any of the companies responsible for all or a portion of such liabilities were to default in its payment of costs or expenses related to any such liability, the Company would be responsible for a portion of the defaulting party or parties’ obligation(s). The Company also provided a default guarantee related to deferred compensation arrangements related to current and former senior officers and directors of Cendant, Realogy and Travelport. These arrangements were valued upon the Separation in accordance with the guidance for guarantees and recorded as liabilities on the Consolidated Balance Sheets. To the extent such recorded liabilities are not adequate to cover the ultimate payment amounts, such excess will be reflected as an expense to the results of operations in future periods.
	As a result of the sale of Realogy on April 10, 2007, Realogy was required to post a letter of credit in an amount acceptable to the Company and Avis Budget Group (formerly known as Cendant) to satisfy its obligations for the Cendant legacy contingent liabilities. As of December 31, 2014, the letter of credit was $53 million.
	As of December 31, 2014, the $38 million of Separation related liabilities is comprised of $34 million for tax liabilities, $1 million for liabilities of previously sold businesses of Cendant, $1 million for other contingent and corporate liabilities and $2 million of liabilities where the calculated guarantee amount exceeded the contingent liability assumed at the Separation Date. In connection with these liabilities, as of December 31, 2014, $26 million is recorded in accrued expenses and other current liabilities and $12 million is recorded in other non-current liabilities on the Consolidated Balance Sheet. The Company will indemnify Cendant for these contingent liabilities and therefore any payments made to the third-party would be through the former Parent. The actual timing of payments relating to these liabilities is dependent on a variety of factors beyond the Company’s control. In addition, the Company had $1 million of receivables due from former Parent and subsidiaries primarily relating to income taxes, as of both December 31, 2014 and 2013, which is recorded in other current assets on the Consolidated Balance Sheets.
	Prior to the Separation, the Company and Realogy were included in the consolidated federal and state income tax returns of Cendant through the Separation date for the 2006 period then ended. The Company is generally liable for 37.5% of certain contingent tax liabilities. In addition, each of the Company, Cendant and Realogy may be responsible for 100% of certain of Cendant’s tax liabilities that will provide the responsible party with a future, offsetting tax benefit.

Accounting Policies [Abstract]
Principles Of Consolidation	PRINCIPLES OF CONSOLIDATION
	When evaluating an entity for consolidation, the Company first determines whether an entity is within the scope of the guidance for consolidation of variable interest entities (“VIE”) and if it is deemed to be a VIE. If the entity is considered to be a VIE, the Company determines whether it would be considered the entity’s primary beneficiary. The Company consolidates those VIEs for which it has determined that it is the primary beneficiary. The Company will consolidate an entity not deemed a VIE upon a determination that it has a controlling financial interest. For entities where the Company does not have a controlling financial interest, the investments in such entities are classified as available-for-sale securities or accounted for using the equity or cost method, as appropriate.
Revenue Recognition	REVENUE RECOGNITION
	Lodging
	The principal source of revenues from franchising hotels is ongoing franchise fees, which are primarily comprised of royalty, marketing and reservation fees. Royalty, marketing and reservation fees are typically a percentage of gross room revenues of each franchised hotel and are recognized as revenue upon becoming due from the franchisee. An estimate of uncollectible ongoing royalty fees is charged to bad debt expense and included in operating expenses on the Consolidated Statements of Income. Lodging revenues also include initial franchise fees, which are recognized as revenues when all material services or conditions have been substantially performed, which is either when a franchised hotel opens for business or when a franchise agreement is terminated after it has been determined that the franchised hotel will not open.
	The Company’s franchise agreements also require the payment of marketing and reservation fees, which are intended to reimburse the Company for expenses associated with operating an international, centralized, brand-specific reservations system, e-commerce channels such as the Company’s brand.com websites, as well as access to third-party distribution channels, such as online travel agents, advertising and marketing programs, global sales efforts, operations support, training and other related services. Marketing and reservation fees are recognized as revenue upon becoming due from the franchisee. An estimate of uncollectible ongoing marketing and reservation fees is charged to bad debt expense and included in marketing and reservation expenses in the Consolidated Statements of Income.
	The Company is contractually obligated to expend the marketing and reservation fees it collects from franchisees in accordance with the franchise agreements; as such, revenues earned in excess of costs incurred are accrued as a liability for future marketing or reservation costs. Costs incurred in excess of revenues earned are expensed as incurred. In accordance with its franchise agreements, the Company includes an allocation of costs required to carry out marketing and reservation activities within marketing and reservation expenses.
	The Company also earns revenues from its Wyndham Rewards loyalty program when a member stays at a participating hotel. These revenues are derived from a fee the Company charges as a percentage of room revenues generated from such stay. This fee is recognized as revenue upon becoming due from the franchisee. Since the Company is obligated to expend the fees it collects from franchisees, revenues earned in excess of costs incurred are accrued as a liability for future costs to support the program.
	The Company also provides management services for hotels under management contracts, which offer all the benefits of a global brand and a full range of management, marketing and reservation services. In addition to the standard franchise services described above, the Company’s hotel management business provides hotel owners with professional oversight and comprehensive operations support services such as hiring, training and supervising the managers and employees that operate the hotels as well as annual budget preparation, financial analysis and extensive food and beverage services. The Company’s standard management agreement typically has a term of up to 25 years. The Company’s management fees are comprised of base fees, which are typically a specified percentage of gross revenues from hotel operations, and incentive fees, which are typically a specified percentage of a hotel’s gross operating profit. Management fee revenues are recognized when earned in accordance with the terms of the contract and recorded as a component of franchise fee revenues on the Consolidated Statements of Income. Management fee revenues were $11 million, $8 million and $7 million during 2014, 2013 and 2012, respectively. The Company also recognizes as revenue reimbursable payroll costs for operational employees at certain of the Company’s managed hotels. Although these costs are funded by hotel owners, accounting guidance requires the Company to report these fees on a gross basis as both revenues and expenses. The revenues are recorded as a component of service and membership fees while the offsetting expenses are reflected as a component of operating expenses on the Consolidated Statements of Income. As such, there is no effect on the Company’s operating income. Revenues related to these payroll costs were $148 million, $129 million and $91 million in 2014, 2013 and 2012, respectively.
	The Company also earns revenues from hotel ownership. The Company’s ownership portfolio is limited to two hotels in locations where we have developed or intend to develop timeshare units. Revenues earned from the Company’s owned hotels consist primarily of (i) gross room revenues, (ii) food and beverage services and (iii) on-site spa, casino, golf and shop revenues. These revenues are recognized upon the completion of services to its guests.
	Vacation Exchange and Rentals
	As a provider of vacation exchange services, the Company enters into affiliation agreements with developers of vacation ownership properties to allow owners of intervals of VOIs to trade their intervals for intervals at other properties affiliated with the Company’s vacation exchange business and, for some members, for other leisure-related services and products. Additionally, as a marketer of vacation rental properties, generally the Company enters into contracts for exclusive periods of time with property owners to market the rental of such properties to rental customers.
	The Company’s vacation exchange business derives a majority of its revenues from annual membership dues and exchange fees from members trading their intervals. Revenues from annual membership dues represent the annual fees from members who participate in the Company’s vacation exchange business and, for additional fees, have the right to exchange their intervals for intervals at other properties affiliated with the Company’s vacation exchange business and, for certain members, for other leisure-related services and products. The Company recognizes revenues from annual membership dues on a straight-line basis over the membership period during which delivery of publications, if applicable, and other services are provided to the members. Exchange fees are generated when members exchange their intervals for intervals at other properties affiliated with the Company’s vacation exchange business or for other leisure-related services and products. Exchange fees are recognized as revenues, net of expected cancellations, when the exchange requests have been confirmed to the member.
	The Company’s vacation rentals business primarily derives its revenues from fees, which generally average between 20% and 50% of the gross booking fees. For properties which the Company owns, manages or operates under long-term capital and operating leases (which represent less than 10% of the Company’s portfolio), the Company receives 100% of the revenues. The majority of the time, the Company acts on behalf of the owners of the rental properties to generate the Company’s fees. The Company provides reservation services to the independent property owners and receives the agreed-upon fee for the services provided. The Company remits the gross rental fee received from the renter to the independent property owner, net of the Company’s agreed-upon fee. Revenues from such fees that are recognized in the period that the rental reservation is made, are recorded net of expected cancellations.
	Cancellations for 2014, 2013 and 2012 each totaled less than 5% of rental transactions booked. Upon confirmation of the rental reservation, the rental customer and property owner generally have a direct relationship for additional services to be performed. The Company also earns rental fees in connection with properties which it owns, manages or operates and such fees are recognized ratably over the rental customer’s stay, as this is the point at which the service is rendered. The Company’s revenues are earned when evidence of an arrangement exists, delivery has occurred or the services have been rendered, the seller’s price to the buyer is fixed or determinable, and collectability is reasonably assured.
	Vacation Ownership
	The Company develops, markets and sells VOIs to individual consumers, provides property management services at resorts and provides consumer financing in connection with the sale of VOIs. The Company’s vacation ownership business derives the majority of its revenues from sales of VOIs and derives other revenues from consumer financing and property management. The Company’s sales of VOIs are either cash sales or developer-financed sales. In order for the Company to recognize revenues from VOI sales under the full accrual method of accounting described in the guidance for sales of real estate for fully constructed inventory, a binding sales contract must have been executed, the statutory rescission period must have expired (after which time the purchasers are not entitled to a refund except for non-delivery by the Company), receivables must have been deemed collectible and the remainder of the Company’s obligations must have been substantially completed. In addition, before the Company recognizes any revenues from VOI sales, the purchaser of the VOI must have met the initial investment criteria and, as applicable, the continuing investment criteria, by executing a legally binding financing contract. A purchaser has met the initial investment criteria when a minimum down payment of 10% is received by the Company.
	In accordance with the guidance for accounting for real estate time-sharing transactions, the Company must also take into consideration the fair value of certain incentives provided to the purchaser when assessing the adequacy of the purchaser’s initial investment. In those cases where financing is provided to the purchaser by the Company, the purchaser is obligated to remit monthly payments under financing contracts that represent the purchaser’s continuing investment.
	If all of the criteria for a VOI sale to qualify under the full accrual method of accounting have been met, as discussed above, except that construction of the VOI purchased is not complete, the Company recognizes revenues using the percentage-of-completion (“POC”) method of accounting provided that the preliminary construction phase is complete and that a minimum sales level has been met (to assure that the property will not revert to a rental property). The preliminary stage of development is deemed to be complete when the engineering and design work is complete, the construction contracts have been executed, the site has been cleared, prepared and excavated, and the building foundation is complete. The completion percentage is determined by the proportion of real estate inventory costs incurred to total estimated costs. These estimated costs are based upon historical experience and the related contractual terms. The remaining revenues and related costs of sales, including commissions and direct expenses, are deferred and recognized as the remaining costs are incurred. During 2014, $12 million of revenues were deferred under the POC method of accounting. During 2013, an immaterial amount of revenues were deferred under the POC method of accounting.
	The Company also offers consumer financing as an option to customers purchasing VOIs, which are typically collateralized by the underlying VOI. The contractual terms of Company-provided financing agreements require that the contractual level of annual principal payments be sufficient to amortize the loan over a customary period for the VOI being financed, which is generally 10 years and payments under the financing contracts begin within 45 days of the sale and receipt of the minimum down payment of 10%. An estimate of uncollectible amounts is recorded at the time of the sale with a charge to the provision for loan losses, which is classified as a reduction of VOI sales on the Consolidated Statements of Income. The interest income earned from the financing arrangements is earned on the principal balance outstanding over the life of the arrangement and is recorded within consumer financing on the Consolidated Statements of Income.
	The Company also provides day-to-day-management services, including oversight of housekeeping services, maintenance and certain accounting and administrative services for property owners’ associations and clubs. In some cases, the Company’s employees serve as officers and/or directors of these associations and clubs in accordance with their by-laws and associated regulations. The Company receives fees for such property management services which are generally based upon total costs to operate such resorts. Fees for property management services typically approximate 10% of budgeted operating expenses. Property management fee revenues are recognized when earned in accordance with the terms of the contract and are recorded as a component of service and membership fees on the Consolidated Statements of Income. Property management revenues, which are comprised of management fee revenue and reimbursable revenue, were $581 million, $567 million and $460 million during 2014, 2013 and 2012, respectively. Management fee revenues were $288 million, $290 million and $225 million during 2014, 2013 and 2012, respectively. Reimbursable revenues, which are based upon certain reimbursable costs with no added margin, were $293 million, $277 million and $235 million during 2014, 2013 and 2012, respectively. These reimbursable costs principally relate to the payroll costs for management of the associations, club and resort properties where the Company is the employer and are reflected as a component of operating expenses on the Consolidated Statements of Income. During each of 2014, 2013 and 2012, one of the associations that the Company manages paid Wyndham Exchange & Rentals $19 million for exchange services.
	Other Items
	The Company records marketing and reservation revenues, Wyndham Rewards revenues, RCI Elite Rewards revenues and hotel/property management services revenues for its Lodging, Vacation Ownership and Vacation Exchange and Rentals segments, in accordance with the guidance for reporting revenues gross as a principal versus net as an agent, which requires that these revenues be recorded on a gross basis.
	Deferred Income
	Deferred income, as of December 31, consisted of:
		2014			2013
	Membership and exchange fees	$	275		$	298
	VOI trial and incentive fees	160			149
	Vacation rental fees	104			109
	Initial franchise fees	49			42
	Other fees	75			45
	Total deferred income	663			643
	Less: Current deferred income	464			451
	Non-current deferred income	$	199		$	192
	Deferred membership and exchange fees consist primarily of payments made in advance for annual memberships that are recognized over the term of the membership period, which is typically one to three years. Deferred VOI trial fees are payments received in advance for a trial VOI, which allows customers to utilize a VOI typically within one year of purchase. Deferred incentive fees represent payments received in advance for additional travel related services and products at the time of a VOI sale. Revenue is recognized when a customer utilizes the additional services and products, which is typically within two years of a VOI sale. Deferred vacation rental fees represent payments received in advance of a rental customer’s stay that are recognized as revenue when the rental stay occurs, which is typically within six months of the confirmation date. Deferred initial franchise fees are recognized when all material services or conditions have been performed which is typically within two years.
Income Taxes	INCOME TAXES
	The Company recognizes deferred tax assets and liabilities using the asset and liability method, under which deferred tax assets and liabilities are calculated based upon the temporary differences between the financial statement and income tax bases of assets and liabilities using currently enacted tax rates. These differences are based upon estimated differences between the book and tax basis of the assets and liabilities for the Company as of December 31, 2014 and 2013.
	The Company’s deferred tax assets are recorded net of a valuation allowance when, based on the weight of available evidence, it is more likely than not that some portion or all of the recorded deferred tax assets will not be realized in future periods. Decreases to the valuation allowance are recorded as reductions to the Company’s provision for income taxes and increases to the valuation allowance result in additional provision for income taxes. The realization of the Company’s deferred tax assets, net of the valuation allowance, is primarily dependent on estimated future taxable income. A change in the Company’s estimate of future taxable income may require an addition to or reduction from the valuation allowance.
	For tax positions the Company has taken or expects to take in a tax return, the Company applies a more likely than not threshold, under which the Company must conclude a tax position is more likely than not to be sustained, assuming that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information, in order to recognize or continue to recognize the benefit. In determining the Company’s provision for income taxes, the Company uses judgment, reflecting its estimates and assumptions, in applying the more likely than not threshold.
Cash And Cash Equivalents	CASH AND CASH EQUIVALENTS
	The Company considers highly-liquid investments purchased with an original maturity of three months or less to be cash equivalents.
Restricted Cash	RESTRICTED CASH
	The largest portion of the Company’s restricted cash relates to securitizations. The remaining portion is comprised of cash held in escrow accounts primarily related to the Company’s vacation ownership business.
	Securitizations: In accordance with the contractual requirements of the Company’s various vacation ownership contract receivable securitizations, a dedicated lockbox account, subject to a blocked control agreement, is established for each securitization. At each month end, the total cash in the collection account from the previous month is analyzed and a monthly servicer report is prepared by the Company, which details how much cash should be remitted to the note holders for principal and interest payments, and any cash remaining is transferred by the trustee back to the Company. Additionally, as required by various securitizations, the Company holds an agreed-upon percentage of the aggregate outstanding principal balances of the VOI contract receivables collateralizing the asset-backed notes in a segregated trust (or reserve) account as credit enhancement. Each time a securitization closes and the Company receives cash from the note holders, a portion of the cash is deposited in the reserve account. Such amounts were $96 million and $92 million, of which $75 million and $64 million is recorded within other current assets and $21 million and $28 million is recorded within other non-current assets as of December 31, 2014 and 2013, respectively, on the Consolidated Balance Sheets.
	Escrow Deposits: Laws in most U.S. states require the escrow of down payments on VOI sales, with the typical requirement mandating that the funds be held in escrow until the rescission period expires. As sales transactions are consummated, down payments are collected and are subsequently placed in escrow until the rescission period has expired. Depending on the state, the rescission period can be as short as 3 calendar days or as long as 15 calendar days. In certain states, the escrow laws require that 100% of VOI purchaser funds (excluding interest payments, if any), be held in escrow until the deeding process is complete. Where possible, the Company utilizes surety bonds in lieu of escrow deposits. Escrow deposit amounts were $51 million and $57 million as of December 31, 2014 and 2013, respectively, which is recorded within other current assets on the Consolidated Balance Sheets.
Receivable Valuation	RECEIVABLE VALUATION
	Trade receivables
	The Company provides for estimated bad debts based on its assessment of the ultimate realizability of receivables, considering historical collection experience, the economic environment and specific customer information. When the Company determines that an account is not collectible, the account is written-off to the allowance for doubtful accounts. The following table illustrates the Company’s allowance for doubtful accounts activity for the year ended December 31:
		2014			2013			2012
	Beginning balance	$	209		$	213		$	207
	Bad debt expense	48			57			53
	Write-offs	(86		)	(64		)	(49		)
	Translation and other adjustments	(2		)	3			2
	Ending balance	$	169		$	209		$	213
	Vacation ownership contract receivables
	In the Company’s Vacation Ownership segment, the Company provides for estimated vacation ownership contract receivable defaults at the time of VOI sales by recording a provision for loan losses as a reduction of VOI sales on the Consolidated Statements of Income. The Company assesses the adequacy of the allowance for loan losses based on the historical performance of similar vacation ownership contract receivables. The Company uses a technique referred to as static pool analysis, which tracks defaults for each year’s sales over the entire life of those contract receivables. The Company considers current defaults, past due aging, historical write-offs of contracts and consumer credit scores (FICO scores) in the assessment of borrower’s credit strength and expected loan performance. The Company also considers whether the historical economic conditions are comparable to current economic conditions. If current or expected future conditions differ from the conditions in effect when the historical experience was generated, the Company adjusts the allowance for loan losses to reflect the expected effects of the current environment on the collectability of the Company’s vacation ownership contract receivables.
Loyalty Programs	LOYALTY PROGRAMS
	The Company operates a number of loyalty programs including Wyndham Rewards, RCI Elite Rewards and other programs. Wyndham Rewards members primarily accumulate points by staying in hotels franchised under one of the Company’s lodging brands. Wyndham Rewards and RCI Elite Rewards members accumulate points by purchasing everyday services and products from the various businesses that participate in the program.
	Members may redeem their points for hotel stays, airline tickets, rental cars, resort vacations, electronics, sporting goods, movie and theme park tickets, gift certificates, vacation ownership maintenance fees and annual membership dues and exchange fees for transactions. The points cannot be redeemed for cash. The Company earns revenue from these programs (i) when a member stays at a participating hotel, from a fee charged by the Company to the franchisee, which is based upon a percentage of room revenues generated from such stay or (ii) based upon a percentage of the members’ spending on the co-branded credit cards and such revenues are paid to the Company by a third-party issuing bank. The Company also incurs costs to support these programs, which primarily relate to marketing expenses to promote the programs, costs to administer the programs and costs of members’ redemptions.
	As members earn points through the Company’s loyalty programs, the Company records a liability of the estimated future redemption costs, which is calculated based on (i) an estimated cost per point and (ii) an estimated redemption rate of the overall points earned, which is determined through historical experience, current trends and the use of an actuarial analysis. Revenues relating to the Company’s loyalty programs are recorded in other revenues in the Consolidated Statements of Income and amounted to $142 million, $113 million and $78 million, while total expenses amounted to $112 million, $93 million and $73 million in 2014, 2013 and 2012, respectively. The liability for estimated future redemption costs as of December 31, 2014 and 2013 amounted to $62 million and $52 million, respectively, and is included in accrued expenses and other current liabilities and other non-current liabilities in the Consolidated Balance Sheets.
Inventory	INVENTORY
	Inventory primarily consists of real estate and development costs of completed VOIs, VOIs under construction, land held for future VOI development, vacation ownership properties, vacation credits and inventory sold subject to conditional repurchase. The Company applies the relative sales value method for relieving VOI inventory and recording the related cost of sales. Under the relative sales value method, cost of sales is calculated as a percentage of net sales using a cost-of-sales percentage ratio of total estimated development cost to total estimated VOI revenue, including estimated future revenue and incorporating factors such as changes in prices and the recovery of VOIs generally as a result of contract receivable defaults. The effect of such changes in estimates under the relative sales value method is accounted for on a retrospective basis through corresponding current-period adjustments to inventory and cost of sales. Inventory is stated at the lower of cost, including capitalized interest, property taxes and certain other carrying costs incurred during the construction process, or net realizable value. Capitalized interest was $2 million, less than $1 million and $1 million in 2014, 2013 and 2012, respectively.
Advertising Expense	ADVERTISING EXPENSE
	Advertising costs are generally expensed in the period incurred. Advertising expenses, which are primarily recorded within marketing and reservation expenses on the Consolidated Statements of Income, were $170 million, $146 million and $105 million in 2014, 2013 and 2012, respectively.
Use Of Estimates and Assumptions	USE OF ESTIMATES AND ASSUMPTIONS
	The preparation of the Consolidated Financial Statements requires the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in the Consolidated Financial Statements and accompanying notes. Although these estimates and assumptions are based on the Company’s knowledge of current events and actions the Company may undertake in the future, actual results may ultimately differ from estimates and assumptions.
Derivatives Instruments	DERIVATIVE INSTRUMENTS
	The Company uses derivative instruments as part of its overall strategy to manage its exposure to market risks primarily associated with fluctuations in foreign currency exchange rates and interest rates. As a matter of policy, the Company does not use derivatives for trading or speculative purposes. All derivatives are recorded at fair value either as assets or liabilities. Changes in fair value of derivatives not designated as hedging instruments and of derivatives designated as fair value hedging instruments are recognized currently in operating income and net interest expense, based upon the nature of the hedged item, in the Consolidated Statements of Income. The effective portion of changes in fair value of derivatives designated as cash flow hedging instruments is recorded as a component of other comprehensive income. The ineffective portion is reported immediately in earnings as a component of operating expense, based upon the nature of the hedged item. Amounts included in other comprehensive income are reclassified into earnings in the same period during which the hedged item affects earnings.
Property And Equipment	PROPERTY AND EQUIPMENT
	Property and equipment (including leasehold improvements) are recorded at cost, and presented net of accumulated depreciation and amortization. Depreciation, recorded as a component of depreciation and amortization on the Consolidated Statements of Income, is computed utilizing the straight-line method over the lesser of the lease terms or estimated useful lives of the related assets. Amortization of leasehold improvements, also recorded as a component of depreciation and amortization, is computed utilizing the straight-line method over the lesser of the estimated benefit period of the related assets or the lease terms. Useful lives are generally 30 years for buildings, up to 20 years for leasehold improvements, from 15 to 30 years for vacation rental properties and from 3 to 7 years for furniture, fixtures and equipment.
	The Company capitalizes the costs of software developed for internal use in accordance with the guidance for accounting for costs of computer software developed or obtained for internal use. Capitalization of software developed for internal use commences during the development phase of the project. The Company generally amortizes software developed or obtained for internal use on a straight-line basis, from 3 to 5 years, commencing when such software is substantially ready for use. The net carrying value of software developed or obtained for internal use was $190 million and $158 million as of December 31, 2014 and 2013, respectively. Capitalized interest was $4 million, $5 million and $4 million in 2014, 2013 and 2012, respectively.
Impairment Of Long-Lived Assets	IMPAIRMENT OF LONG-LIVED ASSETS
	The Company has goodwill and other indefinite-lived intangible assets recorded in connection with business combinations. The Company annually (during the fourth quarter of each year subsequent to completing the Company’s annual forecasting process), or more frequently if circumstances indicate that the value of goodwill may be impaired, reviews the reporting units’ carrying values as required by the guidance for goodwill and other indefinite-lived intangible assets. In accordance with the guidance, the Company has determined that its reporting units are the same as its reportable segments.
	Under current accounting guidance, goodwill and other intangible assets with indefinite lives are not subject to amortization. However, goodwill and other intangibles with indefinite lives are subject to fair value-based rules for measuring impairment, and resulting write-downs, if any, are reflected in operating expense. The Company has goodwill recorded at its lodging, vacation exchange and rentals and vacation ownership reporting units. The Company completed its annual goodwill impairment test by performing a qualitative analysis for each of its reporting units as of October 1, 2014 and determined that no impairment exists.
	The Company also evaluates the recoverability of its other long-lived assets, including property and equipment and amortizable intangible assets, if circumstances indicate impairment may have occurred, pursuant to guidance for impairment or disposal of long-lived assets. This analysis is performed by comparing the respective carrying values of the assets to the current and expected future cash flows, on an undiscounted basis, to be generated from such assets. Property and equipment is evaluated separately within each segment. If such analysis indicates that the carrying value of these assets is not recoverable, the carrying value of such assets is reduced to fair value.
Accounting For Restructuring Activities	ACCOUNTING FOR RESTRUCTURING ACTIVITIES
	The Company’s restructuring actions require it to make significant estimates in several areas including (i) expenses for severance and related benefit costs, (ii) the ability to generate sublease income, as well as its ability to terminate lease obligations and (iii) contract terminations. The amount that the Company has accrued as of December 31, 2014 represents its best estimate of the obligations incurred in connection with these actions, but could be subject to change due to various factors including market conditions and the outcome of negotiations with third parties.
Accumulated Other Comprehensive Income	ACCUMULATED OTHER COMPREHENSIVE INCOME
	Accumulated other comprehensive income (“AOCI”) consists of accumulated foreign currency translation adjustments, accumulated unrealized gains and losses on derivative instruments designated as cash flow hedges and pension related costs. Foreign currency translation adjustments exclude income taxes related to indefinite investments in foreign subsidiaries. Assets and liabilities of foreign subsidiaries having non-U.S.-dollar functional currencies are translated at exchange rates at the Consolidated Balance Sheet dates. Revenues and expenses are translated at average exchange rates during the periods presented. The gains or losses resulting from translating foreign currency financial statements into U.S. dollars, net of hedging gains or losses and taxes, are included in AOCI on the Consolidated Balance Sheets. Gains or losses resulting from foreign currency transactions are included in the Consolidated Statements of Income.
Stock-Based Compensation	STOCK-BASED COMPENSATION
	In accordance with the guidance for stock-based compensation, the Company measures all employee stock-based compensation awards using a fair value method and records the related expense in its Consolidated Statements of Income.
Equity Earnings And Other Income	EQUITY EARNINGS AND OTHER INCOME
	The Company applies the equity method of accounting when it has the ability to exercise significant influence over operating and financial policies of an investee. The Company recorded $2 million, $3 million and $0 of net earnings from such investments during 2014, 2013 and 2012, respectively, in other income, net on the Consolidated Statements of Income.
	During 2014, the Company recorded $5 million of income primarily related to the sale of non-strategic assets and other miscellaneous royalties at its vacation ownership business. During 2013, the Company recorded $3 million of income primarily related to other miscellaneous royalties at its vacation ownership business. In addition, during 2012, the Company recorded $8 million of income primarily related to the settlement of a business disruption claim related to the Gulf of Mexico spill in 2010 and the reversal of allowance associated with previously divested asset.
Recently Issued Accounting Pronouncements	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
	Intangibles - Goodwill and Other. In July 2012, the Financial Accounting Standards Board (the “FASB”) issued guidance on the testing of indefinite-lived intangible assets for impairment, which is intended to reduce the cost and complexity of the impairment test for indefinite-lived intangible assets by providing an entity with the option to first assess qualitatively whether it is necessary to perform the impairment test that is currently in place. An entity would not be required to quantitatively calculate the fair value of an indefinite-lived intangible asset unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. This guidance was effective for interim and annual impairment tests beginning after September 15, 2012, with early adoption permitted. The Company adopted the guidance on October 1, 2012, as required. There was no material impact on the Consolidated Financial Statements resulting from the adoption.
	Comprehensive Income. In February 2013, the FASB issued guidance to improve the reporting of amounts reclassified out of AOCI. The guidance amends the presentation of changes in AOCI and requires an entity to disaggregate the total change of each component of other comprehensive income either on the face of the statement of income or as a separate disclosure in the notes. This guidance is effective prospectively for fiscal years beginning after December 15, 2012. The Company adopted the guidance on January 1, 2013, as required. There was no material impact on its Consolidated Financial Statements resulting from the adoption.
	Foreign Currency Matters. In March 2013, the FASB issued guidance on a parent’s accounting for the cumulative translation adjustment upon derecognition of a subsidiary or group of assets within a foreign entity. The guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. This guidance is effective prospectively for fiscal years beginning after December 15, 2013 and for interim periods within those fiscal years. The Company adopted the guidance on January 1, 2014, as required. There was no material impact on the Consolidated Financial Statements resulting from the adoption.
	Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. In April 2014, the FASB issued guidance on reporting discontinued operations and disclosures of disposals of components of an entity. This guidance changes the criteria for determining which disposals can be presented as discontinued operations and enhances the related disclosure requirements. This guidance is effective for fiscal years beginning after December 15, 2014 and for interim periods within those fiscal years, with early adoption permitted. The Company will adopt this guidance on January 1, 2015, and it believes the adoption of this guidance will not have a material impact on the Consolidated Financial Statements.
	Revenue from Contracts with Customers. In May 2014, the FASB issued guidance on revenue from contracts with customers. The guidance outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This guidance is effective for fiscal years beginning after December 15, 2016 and for interim periods within those fiscal years. The Company is currently evaluating the impact of the adoption of this guidance on the Consolidated Financial Statements.
	Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern. In August 2014, the FASB issued guidance on disclosure of uncertainties about an entity’s ability to continue as a going concern. This guidance addresses management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. The guidance is effective for fiscal years ending after December 15, 2016 and for interim periods within those fiscal years, with early adoption permitted. The Company will adopt this guidance on January 1, 2015, and it believes the adoption of this guidance will not have an impact on the Consolidated Financial Statements.
