Basis Of Presentation [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 interim results reported. The results of operations reported for interim periods are not necessarily indicative of the results of operations for the entire year or any subsequent interim period. These financial statements should be read in conjunction with the Company’s 2012 Consolidated Financial Statements included in its Annual Report filed on Form 10-K with the Securities and Exchange Commission on February 15, 2013.
	Business Description
	The Company operates in the following business segments:
	•	Lodging—primarily franchises hotels in the upper upscale, 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.
	•	Vacation Ownership—develops, markets and sells VOIs to individual consumers, provides consumer financing in connection with the sale of VOIs and provides property management services at resorts.
	Recently Issued Accounting Pronouncements
	Comprehensive Income. In February 2013, the Financial Accounting Standards Board ("FASB") issued guidance to improve the reporting of amounts reclassified out of accumulated other comprehensive income ("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 will adopt the guidance on January 1, 2014, as required, and it believes the adoption of this guidance will not have a material impact on its Consolidated Financial Statements.

Earnings Per Share Reconciliation [Abstract]
Earnings Per Share
		Earnings Per Share
	The computation of basic and diluted earnings per share (“EPS”) is based on net income attributable to Wyndham shareholders divided by the basic weighted average number of common shares and diluted weighted average number of common shares, respectively.
	The following table sets forth the computation of basic and diluted EPS (in millions, except per share data):
		Three Months Ended						Nine Months Ended
		September 30,						September 30,
		2013			2012			2013			2012
	Net income attributable to Wyndham shareholders	$	187		$	159		$	346		$	320

	Earnings per share:
	Basic	$	1.42		$	1.13		$	2.58		$	2.2
	Diluted	1.4			1.11			2.55			2.16
	(a)	Includes unvested dilutive restricted stock units (“RSUs”) which are subject to future forfeitures.
	(b)	Excludes 828,000 performance vested restricted stock units ("PSUs") for both the three and nine months ended September 30, 2013, respectively, and 607,000 PSUs for both the three and nine months ended September 30, 2012, respectively, as the Company has not met the required performance metrics.
	(c)	Represents the dilutive effect of warrants to purchase shares of the Company’s common stock related to the May 2009 issuance of the Company’s convertible notes.
	(d)	Excludes 69,000 stock-settled stock appreciation rights ("SSARs") for the nine months ended September 30, 2013, as their inclusion would have been anti-dilutive to EPS.
	Dividend Payments
	During each of the quarterly periods ended March 31, June 30 and September 30, 2013, the Company paid cash dividends of $0.29 per share ($119 million in the aggregate). During each of the quarterly periods ended March 31, June 30 and September 30, 2012, the Company paid cash dividends of $0.23 per share ($102 million in the aggregate).
	Stock Repurchase Program
	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, 2012	53		$	1,820		$	34.33
	For the nine months ended September 30, 2013	7.9		475			59.84
	As of September 30, 2013	60.9		$	2,295		37.65
	The Company had $782 million of remaining availability in its program as of September 30, 2013.

Acquisitions

Acquisitions [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.
	Vacation Ownership NYC Property. During January 2013, the Company entered into an agreement with a third party partner whereby the partner acquired the Alex hotel in New York City 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 hotel while the Company converts it into VOI inventory. The SPE's preliminary purchase price allocation for this hotel 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 the nine months ended September 30, 2013. This SPE transaction is consistent with the Company's strategy to replenish VOI inventory utilizing its Wyndham Asset Affiliation Model. The consolidation of the SPE was not material to the Company's results of operations, financial position or cash flows (see Note 8 - Variable Interest Entities for more detailed information).

	The Company generates vacation ownership contract receivables by extending financing to the purchasers of its VOIs. Current and long-term vacation ownership contract receivables, net consisted of:
		September 30,			December 31,
		2013			2012
	Current vacation ownership contract receivables:

		2,950			3,016
	Less: Allowance for loan losses	503			445
	Long-term vacation ownership contract receivables, net	$	2,447		$	2,571
	During the three and nine months ended September 30, 2013, the Company’s securitized vacation ownership contract receivables generated interest income of $73 million and $226 million, respectively. During the three and nine months ended September 30, 2012, such amounts were $76 million and $229 million, respectively. Such interest income is included in consumer financing revenues on the Consolidated Statements of Income.
	Principal payments that are contractually due on the Company’s vacation ownership contract receivables during the next twelve months are classified as current on the Consolidated Balance Sheets. During the nine months ended September 30, 2013 and 2012, the Company originated vacation ownership contract receivables of $785 million and $822 million, respectively, and received principal collections of $614 million and $575 million, respectively. The weighted average interest rate on outstanding vacation ownership contract receivables was 13.5% and 13.4% as of September 30, 2013 and December 31, 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, 2012	$	497
	Provision for loan losses	275
	Contract receivables write-offs, net	(211		)
	Allowance for loan losses as of September 30, 2013	$	561
		Amount
	Allowance for loan losses as of December 31, 2011	$	394
	Provision for loan losses	320
	Contract receivables write-offs, net	(228		)
	Allowance for loan losses as of September 30, 2012	$	486
	In accordance with the guidance for accounting for real estate timesharing transactions, the Company recorded a provision for loan losses of $102 million and $275 million as a reduction of net revenues during the three and nine months ended September 30, 2013, respectively, and $124 million and $320 million during the three and nine months ended September 30, 2012, respectively.
	Credit Quality for Financed Receivables and the Allowance for Credit Losses
	The basis of the differentiation within the identified class of financed VOI contract receivables 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 September 30, 2013
		700+			600-699		<600		No Score		Asia Pacific		Total

	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.

	(c)	Vacation credits relate to both the Company’s vacation ownership and vacation exchange and rentals businesses of which $66 million and $69 million as of September 30, 2013 and December 31, 2012, respectively, related to the Company’s vacation exchange and rentals business.
	Inventory that the Company expects to sell within the next twelve months is classified as current on the Consolidated Balance Sheets.
	Inventory Sale Transaction
	During June 2013, the Company sold real property located in Las Vegas, Nevada, to a third party developer, consisting of $114 million of vacation ownership inventory and $3 million of property and equipment. Total consideration was $117 million, of which $87 million was cash and $30 million was a note receivable. The Company recognized no gain or loss on this transaction.
	In accordance with the agreement with the third party developer, the Company has conditional rights and a conditional obligation to repurchase the completed property from the 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 (see Note 12 - 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 this transaction as a sale. The property was sold to a variable interest entity (“VIE”) for which the Company is not the primary beneficiary as the Company does not control the entity's development activities and cannot prevent the entity from selling the property to another party. Accordingly, the Company does not consolidate the VIE.
	In connection with this transaction, the Company has an outstanding obligation of $118 million and a note receivable of $31 million as of September 30, 2013, which are recorded within other non-current liabilities and other non-current assets, respectively, on the Consolidated Balance Sheet. Interest on the note receivable accrues at 3% per annum and is expected to be paid with the principal at maturity in December 2014. The $87 million of cash consideration received is included in proceeds from vacation ownership inventory arrangement in the financing section on the Consolidated Statement of Cash Flows for the nine months ended September 30, 2013. The note receivable and corresponding long-term obligation were non-cash and as such, are excluded from the Company's Consolidated Statement of Cash Flows.

	2.50% Senior Unsecured Notes. During February 2013, the Company issued senior unsecured notes, with face value of $450 million and bearing interest at a rate of 2.50%, for net proceeds of $447 million. Interest began accruing on February 22, 2013 and is payable semi-annually in arrears on March 1 and September 1 of each year, commencing on September 1, 2013. The notes will mature on March 1, 2018 and 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 date. These notes rank equally in right of payment with all of the Company’s other senior unsecured indebtedness.
	3.90% Senior Unsecured Notes. During February 2013, the Company issued senior unsecured notes, with face value of $400 million and bearing interest at a rate of 3.90%, for net proceeds of $397 million. Interest began accruing on February 22, 2013 and is payable semi-annually in arrears on March 1 and September 1 of each year, commencing on September 1, 2013. The notes will mature on March 1, 2023 and 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 date. These notes rank equally in right of payment with all of the Company’s other senior unsecured indebtedness.
	Sierra Timeshare 2013-1 Receivables Funding, LLC. During March 2013, the Company closed a series of term notes payable, Sierra Timeshare 2013-1 Receivables Funding LLC, in the initial principal amount of $300 million at an advance rate of 91%. These borrowings bear interest at a weighted average coupon rate of 1.77% and are secured by vacation ownership contract receivables. As of September 30, 2013, the Company had $213 million of outstanding borrowings under these term notes.
	Sierra Timeshare 2013-2 Receivables Funding, LLC. During July 2013, the Company closed a series of term notes payable, Sierra Timeshare 2013-2 Receivables Funding LLC, in the initial principal amount of $325 million at an advance rate of 98%. These borrowings bear interest at a weighted average coupon rate of 2.68% and are secured by vacation ownership contract receivables. As of September 30, 2013, the Company had $294 million of outstanding borrowings under these term notes.
	Revolving Credit Facility. On May 22, 2013, the Company replaced its $1.0 billion revolving credit facility with a $1.5 billion revolving credit facility that expires on July 15, 2018. This facility is subject to a facility 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 upon the Company's credit ratings. The available capacity of the facility also supports the Company's commercial paper program.
	Commercial Paper. On May 22, 2013, the Company increased its existing commercial paper program by $250 million to a maximum of $750 million. The maturities of the commercial paper notes will vary, but may not exceed 366 days from the date of issue. 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, 2012, the Company classified its outstanding commercial paper borrowings within current portion of long-term debt due to its inability to refinance, if necessary, the outstanding borrowings on a long-term basis due to restrictions contained in the prior revolving credit facility.
	Sierra Timeshare Conduit Receivables Funding II, LLC. On August 29, 2013, the Company renewed its securitized timeshare receivables conduit facility for a two-year period through August 2015. The facility bears interest at variable rates based on commercial paper rates and LIBOR rates plus a spread and the capacity remained at $650 million.
	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 the investing and financing activities within the Company's Consolidated Statement of Cash Flows.
	Other. During January 2013, the Company entered into an agreement with a third party partner whereby the partner acquired a hotel through an SPE. The SPE financed the hotel acquisition 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 is classified as long-term debt (see Note 8 - Variable Interest Entities for more detailed information).
	Fair Value Hedges. During the third quarter of 2013, the Company entered into fixed to variable interest rate swap agreements with notional amounts of $400 million of its 3.90% senior unsecured notes and $100 million of its 4.25% senior unsecured notes. As a result of such interest rate swap agreements, the fixed interest rates on these notes were effectively modified to a variable LIBOR-based index. As of September 30, 2013, the variable interest rates were 2.36% and 2.27% for the 3.90% and 4.25% senior unsecured notes, respectively.
	3.50% Convertible Notes
	During the second quarter of 2012, the Company repaid its 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 call options for proceeds of $33 million. As a result of these transactions, the Company made a net payment of $12 million.
	Concurrent with the issuance of its convertible notes, the Company entered into warrant transactions (“Warrants”) with certain counterparties. The Warrants were separate contracts entered into by the Company and were not part of its convertible notes. During the third quarter of 2012, the Company net share settled all of the outstanding warrants by issuing 613,000 shares of its common stock. As of September 30, 2012, there were no warrants outstanding.
	Early Extinguishment of Debt
	During the first quarter of 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, the Company repurchased a total of $531 million of its outstanding senior unsecured notes and incurred expenses of $111 million during the nine months ended September 30, 2013, which is included within early extinguishment of debt on the Consolidated Statement of Income.
	During the first quarter of 2012, the Company repurchased a portion of its 9.875% and 6.00% senior unsecured notes through tender offers totaling $650 million. In connection with these tender offers, the Company incurred expenses of $2 million and $108 million during the three and nine months ended September 30, 2012, which is included within early extinguishment of debt on the Consolidated Statement of Income.

Variable Interest Entities
		Variable Interest Entities
	In accordance with the applicable accounting guidance for the consolidation of VIEs, the Company analyzes its variable interests, including loans, guarantees, SPEs and equity investments to determine if an entity in which the Company has a variable interest is 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 into its financial statements those VIEs for which it has determined that it is the primary beneficiary.
	Vacation Ownership Contract Receivables Securitizations
	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:
		September 30,		December 31,
		2013		2012
	Securitized contract receivables, gross (a)	$	2,187	$	2,401

	(b)	Included in other current assets ($66 million and $65 million as of September 30, 2013 and December 31, 2012, respectively) and other non-current assets ($35 million and $56 million as of September 30, 2013 and December 31, 2012, respectively) on the Consolidated Balance Sheets.
	(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 $28 million as of both September 30, 2013 and December 31, 2012 related to securitized debt.
	(f)	Included in current ($186 million and $218 million as of September 30, 2013 and December 31, 2012, respectively) and long-term ($1,702 million and $1,742 million as of September 30, 2013 and December 31, 2012, respectively) securitized vacation ownership debt on the Consolidated Balance Sheets.
	(g)	Primarily includes interest rate derivative contracts and accrued interest on securitized debt; included in accrued expenses and other current liabilities ($2 million as of both September 30, 2013 and December 31, 2012) and other non-current liabilities ($3 million as of December 31, 2012) 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 $1,129 million and $985 million as of September 30, 2013 and December 31, 2012, 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:
		September 30,		December 31,
		2013		2012
	SPE assets in excess of SPE liabilities	$	416	$	578

	Less: Allowance for loan losses	561		497
	Total, net	$	984	$	1,066
	In addition to restricted cash related to securitizations, the Company had $61 million and $56 million of restricted cash related to escrow deposits as of September 30, 2013 and December 31, 2012, respectively, which are recorded within other current assets on the Consolidated Balance Sheets.
	Vacation Ownership NYC Property
	During January 2013, the Company entered into an agreement with a third party partner whereby the partner acquired the Alex hotel in New York City through an SPE. The Company is managing and operating the hotel while the Company converts it into VOI inventory. The SPE financed the hotel 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. The Company has 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.
	The assets and liabilities of the SPE are as follows:
		September 30,
		2013
	Cash	$	4
	Property and equipment, net	112
	Total SPE assets	116

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
		September 30, 2013						December 31, 2012

	(b)	Included in other non-current assets on the Consolidated Balance Sheets; carrying value is equal to estimated fair value.
	(c)	Included in accrued expenses and other current liabilities ($1 million as of both September 30, 2013 and December 31, 2012) and other non-current liabilities ($2 million and $3 million as of September 30, 2013 and December 31, 2012, respectively) on the Consolidated Balance Sheets; carrying value is equal to estimated fair value.
	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. 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:
		September 30, 2013				December 31, 2012

	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
		Derivative Instruments and Hedging Activities
	Foreign Currency Risk
	The Company uses freestanding foreign currency forward contracts and foreign currency forward contracts designated as cash flow hedges to manage its exposure to changes in foreign currency exchange rates associated with its foreign currency denominated receivables, forecasted earnings of foreign subsidiaries and forecasted foreign currency denominated vendor payments. The amount of gains or losses the Company expects to reclassify from AOCI to earnings over the next 12 months is not material. The impact of the freestanding foreign currency forward contracts resulted in a gain of $8 million and $6 million during the three and nine months ended September 30, 2013, respectively, and such gains were included in operating expenses on the Company’s Consolidated Statements of Income. The impact of the freestanding foreign currency forward contracts was not material to the Company’s Consolidated Statements of Income during the three and nine months ended September 30, 2012.
	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 the fair value of the derivatives are recorded in income with offsetting adjustments to the carrying amount of the hedged debt. The amount of losses that the Company expects to reclassify from AOCI to earnings during the next 12 months is not material. The impact of the freestanding derivatives was not material to the Company’s Consolidated Statements of Income during the three and nine months ended September 30, 2013 and 2012.
	Gains or losses recognized in AOCI for both the three and nine months ended September 30, 2013 and 2012 were not material.

		Income Taxes
	The Company files income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. The Company is no longer subject to U.S. federal income tax examinations for years prior to 2008. In addition, with few exceptions, the Company is no longer subject to state and local, or non-U.S. income tax examinations for years prior to 2004.
	The Company’s effective tax rate declined from 37.9% during the three months ended September 30, 2012 to 36.8% during the three months ended September 30, 2013 primarily due to the release of a reserve resulting from the expiration of certain statutes of limitation.
	The Company’s effective tax rate declined from 37.0% during the nine months ended September 30, 2012 to 36.7% during the nine months ended September 30, 2013.
	The Company made cash income tax payments, net of refunds, of $134 million and $105 million during the nine months ended September 30, 2013 and 2012, respectively.

	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, Wyndham Hotels & Resorts Inc. and Wyndham Hotel Management Inc., 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 disputes the allegations in the lawsuit and is 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 motion to transfer venue of the lawsuit from Arizona to the Federal District Court for the District of New Jersey was granted. The Company has filed motions to dismiss the FTC's lawsuit, which are pending before the court. 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 $32 million and $42 million as of September 30, 2013 and December 31, 2012, respectively. Such reserve is exclusive of matters relating to the Company’s 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 September 30, 2013, the potential exposure resulting from adverse outcomes of such legal proceedings could, in the aggregate, range up to approximately $13 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.
	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 September 30, 2013, 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.
	In connection with such performance guarantees, as of September 30, 2013, the Company maintained a liability of $39 million, of which $36 million was included in other non-current liabilities and $3 million was included in accrued expenses and other current liabilities on its Consolidated Balance Sheet. As of September 30, 2013, the Company also had a corresponding $44 million asset related to these guarantees, of which $40 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 $1 million and $2 million for the three and nine months ended September 30, 2013, respectively.
	Under such performance guarantees, the Company also had receivables of $18 million and $5 million as of September 30, 2013 and December 31, 2012, respectively, resulting from payments made to date which are subject to recapture and which the Company believes will be recoverable from future operating performance. Such receivables were included in other non-current assets on the Company's Consolidated Balance Sheets.
	Vacation Ownership
	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 this commitment was $309 million as of September 30, 2013.
	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.

Stock-Based Compensation
		Stock-Based Compensation
	The Company has a stock-based compensation plan available to grant RSUs, SSARs, PSUs and other stock or cash-based awards to key employees, non-employee directors, advisors and consultants. Under the Wyndham Worldwide Corporation 2006 Equity and Incentive Plan, as amended, a maximum of 36.7 million shares of common stock may be awarded. As of September 30, 2013, 16.6 million shares remained available.
	Incentive Equity Awards Granted by the Company
	The activity related to incentive equity awards granted by the Company for the nine months ended September 30, 2013 consisted of the following:
		RSUs					SSARs
		Number of RSUs			Weighted Average Grant Price		Number of SSARs		Weighted Average Exercise Price
	Balance as of December 31, 2012	3.1			$	32.41	1.1		$	17.13

	Balance as of September 30, 2013 (a)	2.7		(c)	42.97		1.2	(d)	20.24
	(a)	Aggregate unrecognized compensation expense related to RSUs and SSARs was $93 million as of September 30, 2013, which is expected to be recognized over a weighted average period of 2.7 years.
	(b)	Primarily represents awards granted by the Company on February 28, 2013.
	(c)	Approximately 2.6 million RSUs outstanding as of September 30, 2013 are expected to vest over time.
	(d)	Approximately 1 million SSARs are exercisable as of September 30, 2013. The Company assumes that all unvested SSARs are expected to vest over time. SSARs outstanding as of September 30, 2013 had an intrinsic value of $50 million and have a weighted average remaining contractual life of 1.9 years.
	On February 28, 2013, the Company approved grants of incentive equity awards totaling $54 million to key employees and senior officers of Wyndham in the form of RSUs and SSARs. These awards will vest ratably over a period of 4 years. In addition, on February 28, 2013, the Company approved a grant of incentive equity awards totaling $14 million to key employees and senior officers of Wyndham 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. As of September 30, 2013, there were 828,000 PSUs outstanding with an aggregate unrecognized compensation expense of $20 million.
	The fair value of SSARs granted by the Company on February 28, 2013 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.

	Stock-Based Compensation Expense
	The Company recorded stock-based compensation expense of $13 million and $38 million during the three and nine months ended September 30, 2013, respectively, and $10 million and $31 million during the three and nine months ended September 30, 2012, respectively, related to the incentive equity awards granted by the Company. The Company recognized a net tax benefit of $5 million and $15 million during the three and nine months ended September 30, 2013, respectively, and $4 million and $12 million during the three and nine months ended September 30, 2012, respectively, for stock-based compensation arrangements on the Consolidated Statements of Income. During the nine months ended September 30, 2013, the Company increased its pool of excess tax benefits available to absorb tax deficiencies (“APIC Pool”) by $13 million due to the vesting of RSUs. As of September 30, 2013, the Company’s APIC Pool balance was $75 million.
	The Company paid $26 million and $44 million of taxes for the net share settlement of incentive equity awards during the nine months ended September 30, 2013 and 2012, respectively. Such amounts are included within financing activities on the Consolidated Statements of Cash Flows.

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’s presentation of EBITDA may not be comparable to similarly-titled measures used by other companies.

	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 Vacations Club acquisition. During the nine months ended September 30, 2013, the Company recorded $3 million of facility-related costs, reduced its liability with $5 million of cash payments and reversed $1 million of previously recorded personnel-related costs. The remaining liability of $3 million as of September 30, 2013 is expected to be paid in cash; $1 million of personnel-related by the end of 2013 and $2 million of facility-related by January 2017. From the commencement of the 2012 restructuring plan through September 30, 2013, the Company has incurred a total of $9 million of expenses in connection with such plan.
	In addition to the restructuring plan implemented during 2012, the table below includes activity for prior restructuring plans that are immaterial to the Company. The activity related to costs associated with the Company's restructuring plans is summarized by category as follows:

	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 certain 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 $41 million as of both September 30, 2013 and December 31, 2012. These amounts were comprised of certain 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 certain unresolved contingent matters and certain 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 certain deferred compensation arrangements related to certain 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 (formally known as Cendant) to satisfy its obligations for the Cendant legacy contingent liabilities. As of September 30, 2013, the letter of credit was $53 million.
	As of September 30, 2013, the $41 million of Separation related liabilities is comprised of $36 million for tax liabilities, $1 million for liabilities of previously sold businesses of Cendant, $2 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, $22 million is recorded in current due to former Parent and subsidiaries and $17 million is recorded in long-term due to former Parent and subsidiaries as of September 30, 2013 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 $2 million relating to guarantees is recorded in other current liabilities as of September 30, 2013 on the Consolidated Balance Sheet. The actual timing of payments relating to these liabilities is dependent on a variety of factors beyond the Company’s control. In addition, as of September 30, 2013 and December 31, 2012, the Company had $1 million and $2 million, respectively, of receivables due from former Parent and subsidiaries primarily relating to income taxes, which is recorded in other current assets on the Consolidated Balance Sheets.
