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 2013 Consolidated Financial Statements included in its Annual Report filed on Form 10-K with the Securities and Exchange Commission on February 14, 2014.
	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.
	•	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
	Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern. In August 2014, the Financial Accounting Standards Board (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 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.
	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.

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,

	Dividends:
	Aggregate dividends paid to shareholders	$	44		$	39		$	136		$	119
	(a)	Includes unvested dilutive restricted stock units (“RSUs”) which are subject to future forfeitures.
	(b)	Excludes 423,000 performance vested restricted stock units (“PSUs”) for both the three and nine months ended September 30, 2014 and 828,000 for both the three and nine months ended September 30, 2013, as the Company has not met the required performance metrics.
	(c)	Excludes 15,000 and 10,000 stock-settled stock appreciation rights (“SSARs”) for the three and nine months ended September 30, 2014, respectively, as their inclusion would have been anti-dilutive to EPS.
	(d)	Excludes 69,000 SSARs for the nine months ended September 30, 2013, as their inclusion would have been anti-dilutive to EPS.
	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, 2013	62.7		$	2,410		$	38.44
	For the nine months ended September 30, 2014	6.5		481			74.45
	As of September 30, 2014	69.2		$	2,891		41.8
	The Company had $187 million of remaining availability under its program as of September 30, 2014. The total capacity of the program was increased by proceeds received from stock option exercises.

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.
	During the nine months ended September 30, 2014, the Company completed three business acquisitions for $16 million in cash, net of cash acquired, and $2 million of contingent consideration, related to prior year acquisitions. The preliminary purchase price allocations resulted in the recognition of $9 million of inventory which was 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.

		Vacation Ownership Contract Receivables
	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,
		2014			2013
	Current vacation ownership contract receivables:
	Securitized	$	223		$	222
	Non-securitized	126			140

	Non-securitized	939			975
		2,935			2,957
	Less: Allowance for loan losses	524			509
	Long-term vacation ownership contract receivables, net	$	2,411		$	2,448
	During the three and nine months ended September 30, 2014, the Company’s securitized vacation ownership contract receivables generated interest income of $74 million and $217 million, respectively. During the three and nine months ended September 30, 2013, such amounts were $73 million and $226 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, 2014 and 2013, the Company originated vacation ownership contract receivables of $754 million and $785 million, respectively, and received principal collections of $598 million and $614 million, respectively. The weighted average interest rate on outstanding vacation ownership contract receivables was 13.6% and 13.5% as of September 30, 2014 and December 31, 2013, 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, 2013	$	566
	Provision for loan losses	200
	Contract receivables write-offs, net	(183		)
	Allowance for loan losses as of September 30, 2014	$	583
		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
	In accordance with the guidance for accounting for real estate timesharing transactions, the Company recorded a provision for loan losses of $70 million and $200 million as a reduction of net revenues during the three and nine months ended September 30, 2014, respectively, and $102 million and $275 million during the three and nine months ended September 30, 2013, 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 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, 2014
		700+			600-699		<600		No Score		Asia Pacific		Total
	Current	$	1,538		$	1,043	$	195	$	112	$	279	$	3,167
	31 - 60 days	11			22		16		3		3		55
	61 - 90 days	6			11		12		2		1		32
	91 - 120 days	5			10		11		2		2		30
	Total	$	1,560		$	1,086	$	234	$	119	$	285	$	3,284
		As of December 31, 2013
		700+			600-699		<600		No Score		Asia Pacific		Total
	Current	$	1,515		$	1,060	$	224	$	108	$	280	$	3,187
	31 - 60 days	10			24		20		4		4		62
	61 - 90 days	7			13		13		2		2		37
	91 - 120 days	5			11		13		3		1		33
	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.

	Inventory that the Company expects to sell within the next twelve months is classified as current on the Consolidated Balance Sheets. During 2014, the Company transferred $18 million from property and equipment to VOI inventory.
	Inventory Sale Transactions
	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 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. 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.
	During September 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 connection with such transactions, the Company had outstanding obligations of $103 million as of September 30, 2014, of which $27 million was included within accrued expenses and other current liabilities and $76 million was included within other non-current liabilities on the Consolidated Balance Sheet. As of December 31, 2013, the Company had outstanding obligations of $129 million, of which $47 million was included within accrued expenses and other current liabilities and $82 million was included within other non-current liabilities on the Consolidated Balance Sheet. As of December 31, 2013, the Company had a $30 million note receivable which was included within other current assets on the Consolidated Balance Sheet and accrued interest at 3% per annum (see Note 11 - Commitments and Contingencies for more detailed information).

	Debt Issuances
	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 September 30, 2014, the Company had $315 million of outstanding borrowings under these term notes.
	Sierra Timeshare 2014-2 Receivables Funding, LLC. During July 2014, the Company closed a series of term notes payable, Sierra Timeshare 2014-2 Receivables Funding LLC, with an initial principal amount of $350 million, which are secured by vacation ownership contract receivables and bear interest at a weighted average coupon rate of 2.12%. The advance rate for this transaction was 91%. As of September 30, 2014, the Company had $319 million of outstanding borrowings under these term notes.
	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.

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.
	Fair Value Hedges
	The Company has fixed to variable 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 September 30, 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 Company had a $6 million asset and a $12 million liability recorded as of September 30, 2014 and December 31, 2013, respectively, which represented the aggregate fair value of these interest rate swap agreements.

Variable Interest Entities	'
		Variable Interest Entities
	In accordance with the applicable accounting guidance for the consolidation of a variable interest entity (“VIE”), 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,
		2014			2013
	Securitized contract receivables, gross (a)	$	2,219		$	2,204
	Securitized restricted cash (b)	89			92

	(b)	Included in other current assets ($66 million and $64 million as of September 30, 2014 and December 31, 2013, respectively) and other non-current assets ($23 million and $28 million as of September 30, 2014 and December 31, 2013, 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, 2014 and December 31, 2013, related to securitized debt.
	(f)	Included in current ($192 million and $184 million as of September 30, 2014 and December 31, 2013, respectively) and long-term ($1,749 million and $1,726 million as of September 30, 2014 and December 31, 2013, respectively) securitized vacation ownership debt on the Consolidated Balance Sheets.
	(g)	Primarily includes accrued interest on securitized debt of $1 million and $2 million as of September 30, 2014 and December 31, 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 $1,065 million and $1,115 million as of September 30, 2014 and December 31, 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:
		September 30,			December 31,
		2014			2013
	SPE assets in excess of SPE liabilities	$	384		$	402
	Non-securitized contract receivables	1,065			1,115
	Less: Allowance for loan losses	583			566
	Total, net	$	866		$	951
	In addition to restricted cash related to securitizations, the Company had $61 million and $57 million of restricted cash related to escrow deposits as of September 30, 2014 and December 31, 2013, respectively, which are recorded within other current assets on the Consolidated Balance Sheets.
	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 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.
	The assets and liabilities of the SPE are as follows:
		September 30,			December 31,
		2014			2013
	Cash	$	—		$	4
	Property and equipment, net	66			111

	(*)	As of September 30, 2014, included $71 million for a four-year mortgage note and $6 million of mandatorily redeemable equity, of which $31 million was included in current portion of long-term debt on the Consolidated Balance Sheet. As of December 31, 2013, included $99 million for a four-year mortgage note and $8 million of mandatorily redeemable equity, of which $30 million was included in current portion of long-term debt on the Consolidated Balance Sheet.
	During 2014, the Company purchased $51 million of property and equipment from the SPE.

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, 2014						December 31, 2013
		Fair Value		Level 2		Level 3		Fair Value		Level 2		Level 3

	(b)	Included in other non-current assets on the Consolidated Balance Sheet.
	(c)	Included in accrued expenses and other current liabilities ($7 million and $2 million as of September 30, 2014 and December 31, 2013, respectively) and other non-current liabilities ($1 million and $13 million as of September 30, 2014 and December 31, 2013, 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, 2014				December 31, 2013
		Carrying		Estimated Fair Value		Carrying		Estimated Fair Value
		Amount				Amount
	Assets
	Vacation ownership contract receivables, net	$	2,701	$	3,298	$	2,753	$	3,326
	Debt
	Total debt	4,863		4,950		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
	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. Gains and losses relating to freestanding foreign currency contracts are included in operating expenses on the Company’s Consolidated Statements of Income and are substantially offset by the earnings effect from the underlying items that were economically hedged. The freestanding foreign currency contracts resulted in losses of $12 million and $11 million during the three and nine months ended September 30, 2014, respectively, and gains of $8 million and $6 million during the three and nine months ended September 30, 2013, respectively. The amount of gains or losses relating to contracts designated as cash flow hedges that the Company expects to reclassify from accumulated other comprehensive income (“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 the 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. The impact of the freestanding derivatives was not material to the Company’s Consolidated Statements of Income during both the three and nine months ended September 30, 2014 and 2013.
	Gains or losses recognized in AOCI for both the three and nine months ended September 30, 2014 and 2013 were not material.

	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 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 September 30, 2014 and December 31, 2013, respectively. Such reserves are exclusive of matters relating to the Company’s separation from Cendant (“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, 2014, the potential exposure resulting from adverse outcomes of such legal proceedings could, in the aggregate, range up to $28 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, 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 September 30, 2014, the Company maintained a liability of $35 million, of which $4 million was included in accrued expenses and other current liabilities and $31 million was included in other non-current liabilities on its Consolidated Balance Sheet. As of September 30, 2014, the Company also had a corresponding $40 million asset related to these guarantees, of which $4 million was included in other current assets and $36 million was included in other non-current assets on its Consolidated Balance Sheet. As of December 31, 2013, the Company maintained a liability of $45 million, of which $8 million was included in accrued expenses and other current liabilities and $37 million was included in other non-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 $4 million was included in other current assets and $39 million was included in other non-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 $3 million for the three and nine months ended September 30, 2014, respectively, and $1 million and $2 million for the three and nine months ended September 30, 2013, respectively.
	For guarantees subject to recapture provisions, the Company had a receivable of $31 million as of September 30, 2014, of which $6 million was included in other current assets and $25 million was included in other non-current assets on the Company’s Consolidated Balance Sheet. As of December 31, 2013, the Company had a receivable of $24 million which was included in other non-current assets on the Company’s Consolidated Balance Sheet. 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
	The Company guarantees its vacation ownership subsidiary’s obligations to repurchase completed property in Las Vegas, Nevada and Avon, Colorado from a third party developer subject to the properties meeting the Company’s vacation ownership resort standards and provided that the third party developer has not sold the properties to another party. The maximum potential future payments that the Company could be required to make under these commitments were $365 million as of September 30, 2014.
	The Company entered into a management agreement that provides a guarantee of a certain level of profitability based upon various metrics. As of September 30, 2014, the maximum potential amount of future payments that may be made under this guarantee was $11 million with an annual cap of $1 million.
	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 16 - Separation Adjustments and Transactions with Former Parent and Subsidiaries regarding contingent litigation liabilities resulting from 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, 2014, 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, 2014 consisted of the following:
		RSUs					PSUs					SSARs
		Number of RSUs			Weighted Average Grant Price		Number of PSUs			Weighted Average Grant Price		Number of SSARs			Weighted Average Exercise Price
	Balance as of December 31, 2013	2.6			$	43.11	0.8			$	43.36	1.1			$	21.43

	(a)	Primarily represents awards granted by the Company on February 27, 2014.
	(b)	Aggregate unrecognized compensation expense related to RSUs and SSARs was $95 million as of September 30, 2014, which is expected to be recognized over a weighted average period of 2.7 years.
	(c)	Approximately 2.0 million RSUs outstanding as of September 30, 2014 are expected to vest over time.
	(d)	Maximum aggregate unrecognized compensation expense was $23 million as of September 30, 2014.
	(e)	Approximately 487,000 SSARs are exercisable as of September 30, 2014. The Company assumes that all unvested SSARs are expected to vest over time. SSARs outstanding as of September 30, 2014 had an intrinsic value of $30 million and have a weighted average remaining contractual life of 2.8 years.
	On February 27, 2014, the Company granted 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 four years. In addition, on February 27, 2014, 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.
	The fair value of SSARs granted by the Company on February 27, 2014 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.

	Expected volatility	35.86		%
	Expected life	5.1 years
	Risk free interest rate	1.54		%
	Projected dividend yield	1.92		%
	Stock-Based Compensation Expense

The Company recognized a net tax benefit of $5 million and $17 million during the three and nine months ended September 30, 2014, respectively, and $5 million and $15 million during the three and nine months ended September 30, 2013, respectively, for stock-based compensation arrangements on the Consolidated Statements of Income. During the nine months ended September 30, 2014, the Company increased its pool of excess tax benefits available to absorb tax deficiencies (“APIC Pool”) by $34 million due to the vesting of RSUs, PSUs and SSARS. As of September 30, 2014, the Company’s APIC Pool balance was $112 million.
	The Company paid $63 million and $26 million of taxes for the net share settlement of incentive equity awards during the nine months ended September 30, 2014 and 2013, respectively. Such amounts are included within financing activities on the Consolidated Statements of Cash Flows.

	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 $40 million and $39 million as of September 30, 2014 and December 31, 2013, respectively. 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 (formerly known as Cendant) to satisfy its obligations for the Cendant legacy contingent liabilities. As of September 30, 2014, the letter of credit was $53 million.
	As of September 30, 2014, the $40 million of Separation related liabilities is comprised of $36 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, $26 million is included within current due to former Parent and subsidiaries and $12 million is included within long-term due to former Parent and subsidiaries as of September 30, 2014 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 included within other current liabilities as of September 30, 2014 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, the Company had $1 million of receivables due from former Parent and subsidiaries primarily relating to income taxes, as of both September 30, 2014 and December 31, 2013, which is included within other current assets on the Consolidated Balance Sheets.
