Organization and Business Description	12 Months Ended
Organization and Business Description	Dec. 31, 2013
Accounting Policies [Abstract]
Organization and Business Description	NOTE 1: ORGANIZATION AND BUSINESS DESCRIPTION We refer to TripAdvisor, Inc. and our wholly-owned subsidiaries as “TripAdvisor,” “the Company,” “us,” “we” and “our” in these notes to the consolidated and combined financial statements. During 2011, Expedia, Inc., or Expedia, announced its plan to separate into two independent public companies in order to better achieve certain strategic objectives of its various businesses. We refer to this transaction as the “Spin-Off.” On December 20, 2011, following the close of trading on the NASDAQ Global Select Market (“NASDAQ”), the Spin-Off was completed, and TripAdvisor began trading as an independent public company on December 21, 2011. Expedia effected the Spin-Off by means of a reclassification of its capital stock that resulted in the holders of Expedia capital stock immediately prior to the time of effectiveness of the reclassification having the right to receive a proportionate amount of TripAdvisor capital stock. In connection with the Spin-Off, Expedia contributed or transferred all of the subsidiaries and assets relating to Expedia’s TripAdvisor Media Group to TripAdvisor and TripAdvisor assumed all of the liabilities relating to Expedia’s TripAdvisor Media Group. On December 11, 2012, Liberty Interactive Corporation, or Liberty, purchased an aggregate of 4,799,848 shares of common stock of TripAdvisor from Barry Diller, our former Chairman of the Board of Directors and Senior Executive, and certain of his affiliates (the “Stock Purchase”). As a result, as of December 31, 2013, Liberty beneficially owned 18,159,752 shares of our common stock and 12,799,999 shares of our Class B common stock, which shares constitute 14.0% of the outstanding shares of Common Stock and 100% of the outstanding shares of Class B Common Stock. Assuming the conversion of all of the Liberty’s shares of Class B common stock into common stock, Liberty would beneficially own 21.8% of the outstanding common stock (calculated in accordance with Rule 13d-3). Because each share of Class B common stock generally is entitled to ten votes per share and each share of common stock is entitled to one vote per share, Liberty may be deemed to beneficially own equity securities representing approximately 56.8% of our voting power. Our common stock trades on the NASDAQ under the trading symbol “TRIP.” *Description of Business* TripAdvisor is an online travel company, empowering users to plan and have the perfect trip. TripAdvisor’s travel research platform aggregates reviews and opinions of members about destinations, accommodations (hotels, B&Bs, specialty lodging and vacation rentals), restaurants and activities throughout the world through our flagship TripAdvisor brand. TripAdvisor-branded websites include tripadvisor.com in the United States and localized versions of the website in 33 countries, including in China under the brand daodao.com. Beyond travel-related content, TripAdvisor websites also include links to the websites of our travel advertisers allowing travelers to directly book their travel arrangements. In addition to the flagship TripAdvisor brand, we manage and operate 20 other travel brands, connected by the common goal of providing comprehensive travel planning resources across the travel sector. We derive substantially all of our revenue from advertising, primarily through click-based advertising and display-based advertising sales. In addition, we earn revenue through a combination of subscription-based offerings from our Business Listings and Vacation Rental products, transaction revenue from making hotel room nights available for booking on our transactional sites, and other revenue including licensing our content to third-parties. We have one operating and reportable segment: TripAdvisor. The segment is determined based on how our chief operating decision maker manages our business, makes operating decisions and evaluates operating performance. *Seasonality* Expenditures by travel advertisers tend to be seasonal. Traditionally, our strongest quarter has been the third quarter, which is a key travel research period, with the weakest quarter being the fourth quarter. However, adverse economic conditions or continued growth of our international operations with differing holiday peaks may influence the typical trend of our seasonality in the future.

Significant Accounting Policies

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying consolidated and combined financial statements include TripAdvisor, our wholly-owned subsidiaries, and entities we control, or in which we have a variable interest and are the primary beneficiary of expected cash profits or losses. We record our investments in entities that we do not control, but over which we have the ability to exercise significant influence, using the equity method. We record noncontrolling interest in our consolidated and combined financial statements to recognize the minority ownership interest in our consolidated and combined subsidiaries. Noncontrolling interest in the earnings and losses of consolidated and combined subsidiaries represent the share of net income or loss allocated to members or partners in our consolidated and combined entities. We have eliminated significant intercompany transactions and accounts. The accounting for income taxes was computed for TripAdvisor on a separate tax return basis (see “Note 9—Income Taxes” for further information). The accompanying consolidated and combined financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”).

Certain of our subsidiaries that operate in China, have variable interests in affiliated entities in China in order to comply with Chinese laws and regulations, which restrict foreign investment in Internet content provision businesses. Although we do not own the capital stock of some of our Chinese affiliates, we consolidate their results as we are the primary beneficiary of the cash losses or profits of these variable interest affiliates and have the power to direct the activities of these affiliates. Our variable interest entities are not material for all periods presented.

The financial statements and related financial information pertaining to the period preceding December 21, 2011 have been presented on a combined basis and reflect the results of TripAdvisor that were ultimately transferred to us as part of the Spin-Off. The financial statements and related financial information pertaining to the period from December 21, 2011 onward have been presented on a consolidated basis. Prior to the Spin-Off, certain functions, including accounting, legal, tax, corporate development, treasury, employee benefits, financial reporting and real estate management, were historically managed by the corporate division of Expedia on behalf of its subsidiaries. The assets, liabilities and expenses related to the support of these centralized corporate functions have been allocated to us on a specific identification basis to the extent possible. Otherwise, allocations related to these services, in the form of a shared services fee, were primarily based upon an estimate of the proportion of corporate amounts applicable to us. These allocations were determined on a basis that Expedia and we considered to be a reasonable reflection of the cost of services provided or the benefit received by us. These expenses were allocated based on a number of factors including headcount, estimated time spent and operating expenses. In the opinion of management, the assumptions and allocations were made on a reasonable basis. Management believes that amounts allocated to TripAdvisor reflect a reasonable representation of the types of costs that would have been incurred if we had performed these functions as a stand-alone company. However, as estimation is inherent within the aforementioned allocation process, these combined financial statements do not include all of the actual amounts that would have been incurred had we been a stand-alone entity during the periods presented and also do not necessarily reflect our future financial position, results of operations and cash flows.

Accounting Estimates

We use estimates and assumptions in the preparation of our consolidated and combined financial statements in accordance with GAAP. Our estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our consolidated and combined financial statements. These estimates and assumptions also affect the reported amount of net income or loss during any period. Our actual financial results could differ significantly from these estimates. The significant estimates underlying our consolidated and combined financial statements include recoverability of long-lived assets and investments, recoverability of intangible assets and goodwill; income taxes; useful lives of property and equipment; purchase accounting and stock-based compensation.

Reclassifications

Certain reclassifications have been made to conform the prior period to the current presentation. These reclassifications had no net effect on our consolidated and combined financial statements and were not material.

Revenue Recognition

We recognize revenue from the advertising services rendered when the following four revenue recognition criteria are met: persuasive evidence of an arrangement exists, services have been rendered, the price is fixed or determinable, and collectability is reasonably assured.

Click-based Advertising. Revenue is derived primarily from click-through fees charged to our travel partners for traveler leads sent to the travel partners’ website. We record revenue from click-through fees after the traveler makes the click-through to the travel partners’ websites.

Display and Other Advertising. We recognize display advertising revenue ratably over the advertising period or upon delivery of advertising impressions, depending on the terms of the advertising contract. Subscription-based revenue is recognized ratably over the related subscription period. We recognize revenue from all other sources either upon delivery or when we provide the service.

Deferred revenue, which primarily relates to our subscription-based programs, is recorded when payments are received in advance of our performance as required by the underlying agreements.

Cost of Revenue

Cost of revenue consists of expenses that are closely correlated or directly related to revenue generation, including ad serving fees, flight search fees, credit card fees and data center costs.

Selling and Marketing

Sales and marketing expenses primarily consist of direct costs, including search engine marketing, or SEM, other traffic acquisition costs, syndication costs and affiliate program commissions, brand advertising and public relations. In addition, our indirect sales and marketing expense consists of personnel and overhead expenses, including salaries, commissions, benefits, stock-based compensation expense and bonuses for sales, sales support, customer support and marketing employees.

Technology and Content

Technology and content expenses consist of personnel and overhead expenses, including salaries and benefits, stock-based compensation expense and bonuses for salaried employees and contractors engaged in the design, development, testing, content support, and maintenance of our websites. Other costs include licensing and maintenance expense.

General and Administrative

General and administrative expenses consist primarily of personnel and related overhead costs, including executive leadership, finance, legal and human resource functions and stock-based compensation as well as professional service fees and other fees including audit, legal, tax and accounting, and other costs including bad debt expense and our charitable foundation costs.

Interest Income

Interest income primarily consists of interest earned and amortization of discounts and premiums on our marketable securities.

Interest Expense

Interest expense primarily consists of interest incurred, commitment fees and debt issuance cost amortization related to our Credit Agreement and Chinese Credit Facilities.

Cash, Cash Equivalents and Marketable Securities

Our cash equivalents consist of highly liquid investments with maturities of 90 days or less at the date of purchase. Our marketable debt and equity securities have been classified and accounted for as available-for-sale. We determine the appropriate classification of our investments at the time of purchase and reevaluate the designations at each balance sheet date. We invest in highly-rated securities, and our investment policy limits the amount of credit exposure to any one issuer, industry group and currency. The policy requires investments to be investment grade, with the primary objective of minimizing the potential risk of principal loss and providing liquidity of investments sufficient to meet our operating and capital spending requirements and debt repayments.

We classify our marketable debt securities as either short-term or long-term based on each instrument’s underlying contractual maturity date and as to whether and when we intend to sell a particular security prior to its maturity date. Marketable debt securities with maturities greater than 90 days at the date of purchase and 12 months or less remaining at the balance sheet date will be classified as short-term and marketable debt securities with maturities greater than 12 months from the balance sheet date will generally be classified as long-term. We classify our marketable equity securities, limited to money market funds and mutual funds, as either short-term or long-term based on the nature of each security and its availability for use in current operations. Our marketable debt and equity securities are carried at fair value, with the unrealized gains and losses, net of taxes, reported in accumulated other comprehensive income (loss) as a component of shareholders’ equity. Fair values are determined for each individual security in the investment portfolio.

Realized gains and losses on the sale of securities are determined by specific identification of each security’s cost basis. We may sell certain of our marketable securities prior to their stated maturities for strategic reasons including, but not limited to, anticipation of credit deterioration and liquidity and duration management. The weighted average maturity of our total invested cash shall not exceed 18 months, and no security shall have a final maturity date greater than three years.

We continually review our available for sale securities to determine whether a decline in fair value below the carrying value is other than temporary. When evaluating an investment for other-than-temporary impairment, we review factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer and any changes thereto, and our intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of the investment’s cost basis. Once a decline in fair value is determined to be other than temporary, an impairment charge is recorded and a new cost basis in the investment is established. If we do not intend to sell the debt security, but it is probable that we will not collect all amounts due, then only the impairment due to the credit risk would be recognized in earnings and the remaining amount of the impairment would be recognized in accumulated other comprehensive loss within stockholders’ equity.

Cash consists of cash deposits held in global financial institutions.

Fair Value Measurements

We apply fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. We measure assets and liabilities at fair value based on the expected exit price, which is the amount that would be received on the sale of an asset or amount paid to transfer a liability, as the case may be, in an orderly transaction between market participants in the principal or most advantageous market in which we would transact. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability at the measurement date. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs, used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value:

Level 1—Valuations are based on quoted prices for identical assets and liabilities in active markets.

Level 2—Valuations are based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3—Valuations are based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.

Derivative Financial Instruments

Our goal in managing our foreign exchange risk is to reduce, to the extent practicable, our potential exposure to the changes that exchange rates might have on our earnings, cash flows and financial position. We account for our derivative instruments as either assets or liabilities and carry them at fair value.

For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income (loss) in shareholders’ equity and reclassified into income in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument, if any, is recognized in current income. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions. For options designated as cash flow hedges, changes in the time value are excluded from the assessment of hedge effectiveness and are recognized in income. For derivative instruments that hedge the exposure to changes in the fair value of an asset or a liability and that are designated as fair value hedges, both the net gain or loss on the derivative instrument as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in earnings in the current period. The net gain or loss on the effective portion of a derivative instrument that is designated as an economic hedge of the foreign currency translation exposure of the net investment in a foreign operation is reported in the same manner as a foreign currency translation adjustment. For forward exchange contracts designated as net investment hedges, we exclude changes in fair value relating to changes in the forward carrying component from its definition of effectiveness. Accordingly, any gains or losses related to this component are recognized in current income. We have not entered into any cash flow, fair value or net investment hedges to date as of December 31, 2013.

Derivatives that do not qualify for hedge accounting must be adjusted to fair value through current income. In certain circumstances, we enter into foreign currency forward exchange contracts (“forward contracts”) to reduce the effects of fluctuating foreign currency exchange rates on our cash flows denominated in foreign currencies. Our derivative instruments or forward contracts that were entered into and are not designated as hedges as of December 31, 2013 are disclosed below in “Note 5—Financial Instruments” in the notes to the consolidated and combined financial statements. Monetary assets and liabilities denominated in a currency other than the functional currency of a given subsidiary are remeasured at spot rates in effect on the balance sheet date with the effects of changes in spot rates reported in Other, net on our consolidated and combined statements of operations. Accordingly, fair value changes in the forward contracts help mitigate the changes in the value of the remeasured assets and liabilities attributable to changes in foreign currency exchange rates, except to the extent of the spot-forward differences. These differences are not expected to be significant due to the short-term nature of the contracts, which typically have average maturities at inception of less than one year.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are generally due within 30 days and are recorded net of an allowance for doubtful accounts. We record accounts receivable at the invoiced amount and do not charge interest. Collateral is not required for accounts receivable. We consider accounts outstanding longer than the contractual payment terms as past due. We determine our allowance by considering a number of factors, including the length of time trade accounts receivable are past due, previous loss history, a specific customer’s ability to pay its obligations to us, and the condition of the general economy and industry as a whole.

The following table presents the changes in the allowance for doubtful accounts for the periods presented:


	December 31,
	2013			2012			2011
	(in thousands)
Allowance for doubtful accounts:
Balance, beginning of period	$	2,818		$	5,370		$	5,184
Charges (recoveries) to earnings		1,485			(1,050	)		909
Write-offs, net of recoveries and other adjustments		(1,003	)		(1,502	)		(723	)

Balance, end of period	$	3,300		$	2,818		$	5,370

Property and Equipment, Including Website and Software Development Costs

We record property and equipment at cost, net of accumulated depreciation. We capitalize certain costs incurred during the application development stage related to the development of websites and internal use software when it is probable the project will be completed and the software will be used as intended. Capitalized costs include internal and external costs, if direct and incremental, and deemed by management to be significant. We expense costs related to the planning and post-implementation phases of software and website development as these costs are incurred. Maintenance and enhancement costs (including those costs in the post-implementation stages) are typically expensed as incurred, unless such costs relate to substantial upgrades and enhancements to the website or software resulting in added functionality, in which case the costs are capitalized.

We compute depreciation using the straight-line method over the estimated useful lives of the assets, which is three to five years for computer equipment and purchased software, capitalized software and website development and furniture and other equipment. We depreciate leasehold improvements using the straight-line method, over the shorter of the estimated useful life of the improvement or the remaining term of the lease.

Leases

We lease office space in several countries around the world under non-cancelable lease agreements. We generally lease our office facilities under operating lease agreements. Office facilities subject to an operating lease and the related lease payments are not recorded on our balance sheet. The terms of certain lease agreements provide for rental payments on a graduated basis, however, we recognize rent expense on a straight-line basis over the lease period in accordance with authoritative accounting guidance. Any lease incentives are recognized as reductions of rental expense on a straight-line basis over the term of the lease. The lease term begins on the date we become legally obligated for the rent payments or when we take possession of the office space, whichever is earlier.

We establish assets and liabilities for the estimated construction costs incurred under lease arrangements where we are considered the owner for accounting purposes only, or build-to-suit leases, to the extent we are involved in the construction of structural improvements or take construction risk prior to commencement of a lease. Upon occupancy of facilities under build-to-suit leases, we assess whether these arrangements qualify for sales recognition under the sale-leaseback accounting guidance. If we continue to be the deemed owner, the facilities are accounted for as financing leases.

Recoverability of Goodwill and Indefinite-Lived Intangible Assets

Goodwill

We account for acquired businesses using the purchase method of accounting which requires that the assets acquired and liabilities assumed be recorded at the date of acquisition at their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. We assess goodwill, which is not amortized, for impairment annually as of October 1, or more frequently, if events and circumstances indicate impairment may have occurred. We test goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment). We have one reportable segment. The segment is determined based on how our chief operating decision maker manages our business, makes operating decisions and evaluates operating performance.

In the evaluation of goodwill for impairment, we first perform a qualitative assessment to determine whether it is more likely than not (i.e., a likelihood of more than 50%) that the fair value of the reporting unit is less than the carrying amount. If we determine that it is not more likely than not that the fair value of the goodwill is less than its carrying amount, no further testing is necessary. If, however, we determine that it is more likely than not that the fair value of the goodwill is less than its carrying amount, we then perform a quantitative assessment and compare the fair value of the reporting unit to the carrying value. If the carrying value of a reporting unit exceeds its fair value, the goodwill of that reporting unit is potentially impaired and we proceed to step two of the impairment analysis. In step two of the analysis, we will record an impairment loss equal to the excess of the carrying value of the reporting unit’s goodwill over its implied fair value should such a circumstance arise.

Indefinite-Lived Intangible Assets

Intangible assets that have indefinite lives are not amortized and are tested for impairment annually on October 1, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Similar to the qualitative assessment for goodwill, we may assess qualitative factors to determine if it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. If we determine that it is not more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount, no further testing is necessary. If, however, we determine that it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount, we compare the fair value of the indefinite-lived asset with its carrying amount. If the carrying value of an individual indefinite-lived intangible asset exceeds its fair value, the individual asset is written down by an amount equal to such excess. The assessment of qualitative factors is optional and at our discretion. We may bypass the qualitative assessment for any indefinite-lived intangible asset in any period and resume performing the qualitative assessment in any subsequent period.

As part of our qualitative assessment for our 2013 impairment analysis , the factors that we considered for our goodwill and indefinite-lived intangible assets included, but were not limited to: (a) changes in macroeconomic conditions in the overall economy and the specific markets in which we operate, (b) our ability to access capital, (c) changes in the online travel industry, (d) changes in the level of competition, (e) comparison of our current financial performance to historical and budgeted results, (f) changes in excess market capitalization over book value based on our current common stock price and latest consolidated balance sheet, and (g) comparison of the excess of the fair value of our trade names and trademarks to the carrying value of those same assets, using the results of our most recent quantitative assessment. After considering these factors and the impact that changes in such factors would have on the inputs used in our previous quantitative assessment, we determined for our goodwill and indefinite-lived intangible assets that it was more likely than not that these assets were not impaired.

Since the annual impairment tests in October 2013, there have been no events or changes in circumstances to indicate any potential impairment to goodwill or our indefinite lived intangible assets. In the event that future circumstances indicate that any portion of our goodwill or our indefinite-lived intangibles is impaired, an impairment charge would be recorded.

Recoverability of Intangible Assets with Definite Lives and Other Long-Lived Assets

Intangible assets with definite lives and other long-lived assets are carried at cost and are amortized on a straight-line basis over their estimated useful lives of two to eleven years. The straight-line method of amortization is currently used for our definite-lived intangible assets as it approximates, or is our best estimate, of the distribution of the economic use of our identifiable intangible assets. We review the carrying value of long-lived assets or asset groups, including property and equipment, to be used in operations whenever events or changes in circumstances indicate that the carrying amount of the assets might not be recoverable.

Factors that would necessitate an impairment assessment include a significant adverse change in the extent or manner in which an asset is used, a significant adverse change in legal factors or the business climate that could affect the value of the asset, or a significant decline in the observable market value of an asset, among others. If such facts indicate a potential impairment, we assess the recoverability of the asset by determining if the carrying value of the asset exceeds the sum of the projected undiscounted cash flows expected to result from the use and eventual disposition of the asset over the remaining economic life of the asset. If the recoverability test indicates that the carrying value of the asset is not recoverable, we will estimate the fair value of the asset using appropriate valuation methodologies which would typically include an estimate of discounted cash flows. Any impairment would be measured by the amount that the carrying value of such assets exceeds their fair value. We have not identified any circumstances that would warrant an impairment assessment as of December 31, 2013.

Income Taxes

We compute and account for our income taxes on a stand-alone basis. We record income taxes under the liability method. Deferred tax assets and liabilities reflect our estimation of the future tax consequences of temporary differences between the carrying amounts of assets and liabilities for book and tax purposes. We determine deferred income taxes based on the differences in accounting methods and timing between financial statement and income tax reporting. Accordingly, we determine the deferred tax asset or liability for each temporary difference based on the enacted tax rates expected to be in effect when we realize the underlying items of income and expense. We consider all relevant factors when assessing the likelihood of future realization of our deferred tax assets, including our recent earnings experience by jurisdiction, expectations of future taxable income, and the carryforward periods available to us for tax reporting purposes, as well as assessing available tax planning strategies. We may establish a valuation allowance to reduce deferred tax assets to the amount we believe is more likely than not to be realized. Due to inherent complexities arising from the nature of our businesses, future changes in income tax law, tax sharing agreements or variances between our actual and anticipated operating results, we make certain judgments and estimates. Therefore, actual income taxes could materially vary from these estimates.

We recognize in our consolidated and combined financial statements the impact of a tax position, if that position is more likely than not to be sustained upon an examination, based on the technical merits of the position.

Foreign Currency Translation and Transaction Gains and Losses

Our consolidated and combined financial statements are reported in U.S. dollars. Certain of our subsidiaries outside of the United States use the related local currency as their functional currency and not the U.S. dollar. Therefore assets and liabilities of our foreign subsidiaries are translated at the spot rate in effect at the applicable reporting date, and the consolidated and combined statements of operations are translated at the average exchange rates in effect during the applicable period. The resulting unrealized cumulative translation adjustment, net of applicable income taxes, is recorded as a component of accumulated other comprehensive earnings in stockholders’ equity.

Due to the nature of our operations and our corporate structure, we also have subsidiaries that have transactions in foreign currencies other than their functional currency. Transactions denominated in currencies other than the functional currency are recorded based on exchange rates at the time such transactions arise. Subsequent changes in exchange rates result in transaction gains and losses which are reflected in the accompanying consolidated and combined statements of operations as unrealized (based on the applicable period-end exchange rate) or realized upon settlement of the transactions.

Accordingly, we have recorded foreign exchange losses of $0.2 million, 3.2 million and $1.0 million for the years ended December 31, 2013, 2012 and 2011, respectively, in Other, net. These losses are net of those realized and unrealized on foreign currency forward contracts.

Advertising Expense

We incur advertising expense consisting of traffic generation costs from search engines and Internet portals, other online and offline (including television) advertising expense, promotions and public relations to promote our brands. We expense the costs associated with communicating the advertisements in the period in which the advertisement takes place. We expense the production costs associated with advertisements in the period in which the advertisement first takes place. For the years ended December 31, 2013, 2012 and 2011, our advertising expense was $236.5 million, $175.0 million, and $135.6 million, respectively. As of December 31, 2013 and 2012, we had $1.3 million and $1.4 million of prepaid marketing expenses included in prepaid expenses and other current assets.

Stock-Based Compensation

Stock Options. The exercise price for all stock options granted by us to date has been equal to the market price of the underlying shares of common stock at the date of grant. In this regard, when making stock option awards, our practice is to determine the applicable grant date and to specify that the exercise price shall be the closing price of our common stock on the date of grant.

The estimated fair value of stock options is calculated using a Black-Scholes Merton option-pricing model (“Black-Scholes model”). The Black-Scholes model incorporates assumptions to value stock-based awards, which includes the risk-free rate of return, expected volatility, expected term and expected dividend yield.

Our risk-free interest rate is based on the rates currently available on zero-coupon U.S. Treasury issues, in effect at the time of the grant, whose remaining maturity period most closely approximates the stock option’s expected term assumption. We estimate volatility of our common stock by using an average of our historical stock price volatility and of publicly traded companies that we consider peers based on daily price observations over a period equivalent to or approximate to the expected term of the stock option grants. The decision to use a weighted average volatility factor with a peer group was based upon the relatively short period of availability of data on our common stock. We estimate our expected term using the simplified method for all stock options as we do not have sufficient historical exercise data on our common stock. Our expected dividend yield is zero, as we have not paid any dividends on our common stock to date and do not expect to pay any cash dividends for the foreseeable future.

Restricted Stock Units. RSUs are stock awards that are granted to employees entitling the holder to shares of our common stock as the award vests. RSUs are measured at fair value based on the number of shares granted and the quoted price of our common stock at the date of grant. We amortize the fair value of stock options and RSUs, net of estimated forfeitures, as stock-based compensation expense over the vesting term of generally four years on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive these awards, and subsequent events are not indicative of the reasonableness of our original estimates of fair value. We use historical data to estimate pre-vesting stock option and RSU forfeitures and record share-based compensation expense only for those awards that are expected to vest. Changes in estimated forfeitures are recognized through a cumulative catch-up adjustment in the period of change which also impacts the amount of stock compensation expense to be recognized in future periods.

Performance-based stock options and RSUs vest upon achievement of certain company-based performance conditions and a requisite service period. On the date of grant, the fair value of performance-based awards is determined based on the fair value, which is calculated using the same method as our service based stock options and RSUs described above. We then assess whether it is probable that the performance targets would be achieved. If assessed as probable, compensation expense will be recorded for these awards over the estimated performance period. At each reporting period, we will reassess the probability of achieving the performance targets and the performance period required to meet those targets. The estimation of whether the performance targets will be achieved and of the performance period required to achieve the targets requires judgment, and to the extent actual results or updated estimates differ from our current estimates, the cumulative effect on current and prior periods of those changes will be recorded in the period estimates are revised, or the change in estimate will be applied prospectively depending on whether the change affects the estimate of total compensation cost to be recognized or merely affects the period over which compensation cost is to be recognized. The ultimate number of shares issued and the related compensation expense recognized will be based on a comparison of the final performance metrics to the specified targets.

Deferred Merchant Payables

We receive cash from travelers at the time of booking related to our vacation rental and transaction-based businesses and we record these amounts, net of commissions, on our consolidated balance sheets as deferred merchant payables. We pay the hotel or vacation rental owners after the travelers’ use and subsequent billing from the hotel or vacation rental owners. Therefore, we receive cash from the traveler prior to paying the hotel or vacation rental owners, and this operating cycle represents a working capital source of cash to us. As long as our transaction-based businesses grow, we expect that changes in working capital related to these transactions will positively impact operating cash flows. As of December 31, 2013, our deferred merchant payables balance was $29.6 million and for the year ended December 31, 2013, the related transactions generated positive operating cash flow of $16.8 million. A payable balance of $11.5 million was acquired with our business acquisitions during the year ended December 31, 2013, and therefore is included within investing activities in our consolidated and combined cashflow statements. For additional information on our business acquisitions refer to “Note 3—Acquisitions” below. The deferred merchant payables balance at December 31, 2012 was $1.3 million.

Credit Risk and Concentrations

Financial instruments, which potentially subject us to concentration of credit risk, consist primarily of cash and cash equivalents, corporate debt securities, foreign exchange contracts, accounts receivable and customer concentrations. We maintain some cash and cash equivalents balances with financial institutions that are in excess of Federal Deposit Insurance Corporation insurance limits. Our cash and cash equivalents are primarily composed of prime institutional money market funds as well as bank account balances primarily denominated in U.S. dollars, Euros, British pound sterling, Chinese renminbi and Singapore dollars. We invest in highly-rated corporate debt securities, and our investment policy limits the amount of credit exposure to any one issuer, industry group and currency. Our credit risk related to corporate debt securities is also mitigated by the relatively short maturity period required by our investment policy. Foreign exchange contracts are transacted with various international financial institutions with high credit standing.

Our business is also subject to certain risks due to concentrations related to dependence on our relationships with our customers. We are highly dependent on our advertising and media relationship with Expedia, (see “Note 15—Related Party Transactions”). For the years ended December 31, 2013, 2012 and 2011 our two most significant advertising customers, Expedia and Priceline, accounted for a combined 47%, 48% and 49% of total revenue, respectively. As of December 31, 2013 and 2012, there were no customers that accounted for 10% or more of our accounts receivable. Our overall credit risk related to accounts receivable is mitigated by the relatively short collection period.

Contingent Liabilities

Periodically, we review the status of all significant outstanding matters to assess any potential financial exposure. When (i) it is probable that an asset has been impaired or a liability has been incurred and (ii) the amount of the loss can be reasonably estimated, we record the estimated loss in our consolidated and combined statements of operations. We provide disclosure in the notes to the consolidated and combined financial statements for loss contingencies that do not meet both these conditions if there is a reasonable possibility that a loss may have been incurred that would be material to the financial statements. Significant judgment is required to determine the probability that a liability has been incurred and whether such liability is reasonably estimable. We base accruals made on the best information available at the time which can be highly subjective. The final outcome of these matters could vary significantly from the amounts included in the accompanying consolidated and combined financial statements.

Comprehensive Income (Loss)

Comprehensive loss currently consists of net income (loss), cumulative foreign currency translation adjustments, and unrealized gains and losses on available-for-sale securities, net of tax.

Earnings per Share (EPS)

In connection with the Spin-Off a one-for-two reverse stock split of outstanding Expedia capital stock occurred immediately prior to the Spin-Off, which resulted in 120,661,020 shares of common stock and 12,799,999 shares of Class B common stock outstanding immediately following the Spin-Off.

Basic Earnings Per Share

We compute basic earnings per share by dividing net income attributable to TripAdvisor by the weighted average number of common shares outstanding during the period. We compute the weighted average number of common shares outstanding during the reporting period using the total of common stock and Class B common stock outstanding as of the last day of the previous year end reporting period plus the weighted average of any additional shares issued and outstanding less the weighted average of any treasury shares repurchased during the reporting period.

For the year ended December 31, 2011, we computed basic earnings per share using the number of shares of common stock and Class B common stock outstanding immediately following the Spin-Off, as if such shares were outstanding for the entire period prior to the Spin-Off, plus the weighted average of any additional shares issued and outstanding following the Spin-Off date through December 31, 2011.

Diluted Earnings Per Share

We compute diluted earnings per share by dividing net income attributable to TripAdvisor by the sum of the weighted average number of common and common equivalent shares outstanding during the period. We computed the weighted average number of common and common equivalent shares outstanding during the period using the sum of (i) the number of shares of common stock and Class B common stock used in the basic earnings per share calculation as indicated above, and (ii) if dilutive, the incremental weighted average common stock that we would issue upon the assumed exercise of outstanding common equivalent shares related to stock options, stock warrants and the vesting of restricted stock units using the treasury stock method, and (iii) if dilutive, performance based awards based on the number of shares that would be issuable as of the end of the reporting period assuming the end of the reporting period was also the end of the contingency period.

We treated all outstanding equity awards assumed at Spin-Off as if they were granted as of the Spin-Off and we included them in our diluted earnings per share calculation for the year ended December 31, 2011, based on the number of days they were outstanding.

Under the treasury stock method, the assumed proceeds calculation includes the actual proceeds to be received from the employee upon exercise, the average unrecognized compensation cost during the period and any tax benefits credited upon exercise to additional paid-in-capital. The treasury stock method assumes that a company uses the proceeds from the exercise of an award to repurchase common stock at the average market price for the period. Windfall tax benefits created upon the exercise of an award would be added to assumed proceeds, while shortfalls charged to additional paid-in-capital would be deducted from assumed proceeds. Any shortfalls not covered by the windfall tax pool would be charged to the income statement and would be excluded from the calculation of assumed proceeds, if any.

Below is a reconciliation of the weighted average number of shares of common stock outstanding in calculating diluted earnings per share (in thousands, except for per share information) for the periods presented:


	Year Ended December 31,
	2013		2012		2011

The following potential common shares related to stock options, stock warrants and RSUs were excluded from the calculation of diluted net income per share because their effect would have been anti-dilutive for the periods presented:


	December 31,
	2013 (1)		2012 (2)(3)		2011 (3)
	(In thousands)

RSUs		27		21		80
Warrants		—		—		8,047

Total		2,271		3,965		10,388

(1)

These totals do not include 155,000 performance based options and 44,000 performance based RSUs representing the right to acquire 199,000 shares of common stock for which all targets required to trigger vesting have not been achieved; therefore, such awards were excluded from the calculation of weighted average shares used to compute diluted earnings per share for those reporting periods.

(2)

These totals do not include performance based options representing the right to acquire 110,000 shares of common stock, respectively, for which all targets required to trigger vesting had not been achieved; therefore, such awards were excluded from the calculation of weighted average shares used to compute diluted earnings per share for those reporting periods.

(3)

These totals do not include performance based RSUs representing the right to acquire 200,000 and 400,000 shares of common stock at December 31, 2012 and 2011, respectively, for which all targets required to trigger vesting had not been achieved; therefore, such awards were excluded from the calculation of weighted average shares used to compute diluted earnings per share for those reporting periods.

The earnings per share amounts are the same for common stock and Class B common stock because the holders of each class are legally entitled to equal per share distributions whether through dividends or in liquidation.

Recently Adopted Accounting Pronouncements

Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income

In February 2013, the Financial Accounting Standards Board, or FASB, issued new accounting guidance which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. The new guidance requires that companies present, either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified based on its source and is effective for public companies in interim and annual reporting periods beginning after December 15, 2012. Accordingly, we have adopted these presentation requirements during the first quarter of 2013. The adoption of this new guidance did not have a material impact on our consolidated and combined financial statements or related disclosures.

New Accounting Pronouncements Not Yet Adopted

Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists

In July 2013, the FASB issued new accounting guidance on the presentation of unrecognized tax benefits. The new guidance requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows: to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2013, with early adoption permitted. Accordingly, we plan to adopt these presentation requirements during the first quarter of 2014. The adoption of this new guidance is not expected to have a material impact on our consolidated and combined financial statements or related disclosures.

Business Combinations [Abstract]

Acquisitions

NOTE 3: ACQUISITIONS

During the year ended December 31, 2013, we completed six acquisitions for total cash consideration paid of $34.8 million, net of cash acquired. The total cash consideration is subject to adjustment based on the finalization of working capital adjustments and amounts retained with payment subject to certain indemnification obligations by the respective sellers for our benefit in future periods. We acquired TinyPost, the developer of a product that enables users to write over photos and turn them into stories, Jetsetter, a members-only private sale site for hotel bookings; CruiseWise, a cruise research and planning site; Niumba, a Spain-based vacation rental site; GateGuru, a mobile app with flight and airport information around the world; Oyster, a hotel review website featuring expert reviews and photos covering about 150 cities, all of which complement our existing brands in those areas of the travel ecosystem.

The total purchase price of these acquisitions, all of which were accounted for as purchases of businesses under the acquisition method, have been allocated to the tangible and identifiable intangible assets acquired and the net liabilities assumed based on their respective fair values on the acquisition date. The purchase price allocation of our 2013 acquisitions are preliminary and subject to revision as more information becomes available, but in any case will not be revised beyond 12 months after the acquisition date and any change to the fair value of net liabilities acquired will lead to a corresponding change to the purchase price allocable to goodwill on a retroactive basis. The primary areas of the purchase price allocation that are not yet finalized are related to the fair values of certain liabilities and income tax balances. Acquisition-related costs were expensed as incurred and were $1.6 million during the year ended December 31, 2013 and were not material during the years ended December 31, 2012 and 2011. All acquisition related expenses were included in general and administrative expenses on our consolidated and combined statements of operations.

As no individual acquisition was material, the following table presents the aggregate components of the purchase prices initially recorded for all businesses on our consolidated balance sheets at the respective acquisition dates for the periods presented:


	December 31,
	2013			2012		2011
	(In thousands)
Goodwill (1)	$	29,551		$	3,043	$	6,390
Intangible assets (2)		19,195			—		1,642
Net (liabilities)/assets (3)		(9,936	)		7		(16	)
Deferred tax assets		693			—		—

Total (4)	$	39,503		$	3,050	$	8,016

(1)

The goodwill represents the excess value over both tangible and intangible assets acquired. The goodwill in these transactions is primarily attributable to expected operational synergies, the assembled workforces, and the future development initiatives of the assembled workforces. Goodwill in the amount of $14.1 million is expected to be deductible for tax purposes.

(2)

Identifiable definite-lived intangible assets acquired during 2013 were comprised of developed technology of $2.4 million, trade names of $7.6 million, customer relationships of $8.0 million, and other intangibles of $1.2 million. The overall weighted-average life of the identifiable definite-lived intangible assets acquired in the purchase of the companies during 2013 was 8.0 years, which will be amortized on a straight-line basis over their estimated useful lives from acquisition date. The overall weighted average life of acquired intangible assets during 2011 was 2.8 years.

(3)	Includes cash acquired of $2.9 million, $0 million and $0.1 million during 2013, 2012 and 2011, respectively.

(4)	Subject to adjustment based on (i) final working capital adjustment calculations to be determined, and (ii) indemnification obligations of the acquired company stockholders that remains to be paid of $1.8 million at December 31, 2013.

Our consolidated and combined financial statements include the operating results of all acquired businesses from the date of each acquisition. We did not have any material acquisitions, individually or in the aggregate, during the years 2013, 2012 and 2011; therefore no pro-forma results have been provided.

Other Acquisition Activity

During 2012 we also paid $22.3 million for the remaining noncontrolling interest subsidiary shares related to a 2008 acquisition, which brought our ownership to 100%. This amount is included in financing activities in the consolidated statement of cash flows for 2012.

During 2011, we paid $13 million of contingent purchase consideration under prior acquisitions. The amount in 2011 represented an earn-out payment, of which approximately $10 million and $3 million are recorded to financing activities and operating activities, respectively, in the consolidated and combined statement of cash flows. All contingent consideration accrued and paid was calculated based on the financial performance of the acquired entity to which it relates. We also purchased a subsidiary in China from Expedia for $37 million, or $28 million net of acquired cash. This acquisition was accounted for as a common control transaction, with net liabilities recorded at a carrying value of $4 million, including an additional $7 million of short term borrowings from the Chinese Credit Facilities (refer to “Note 8—Debt” below for further information on the Chinese Credit Facilities). No goodwill or other intangibles were recorded as a result of this acquisition and no contingent payments are outstanding. The difference between the purchase price and the carrying value of the net liabilities was recorded to additional paid in capital. The results of operations from this business are included in our consolidated and combined financial statements from the transaction closing date.

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Stock Based Awards and Other Equity Instruments

NOTE 4: STOCK BASED AWARDS AND OTHER EQUITY INSTRUMENTS

Stock-based Compensation Expense

The following table presents the amount of stock-based compensation related to stock-based awards, primarily stock options and RSUs, on our consolidated and combined statements of operations during the periods presented:


	Year Ended December 31,
	2013			2012			2011
	(In thousands)
Selling and marketing	$	10,643		$	4,622		$	3,216
Technology and content		21,053			11,400			3,931
General and administrative		17,257			14,080			10,197

Total stock-based compensation		48,953			30,102			17,344
Income tax benefit from stock-based compensation		(18,014	)		(10,648	)		(6,504	)

Total stock-based compensation, net of tax effect	$	30,939		$	19,454		$	10,840

The year ended December 31, 2011 includes a one-time modification charge of $8.0 million related to the Spin-Off, primarily due to the modification of vested stock options that remained unexercised at the date of the Spin-Off, which the majority of was recorded to general and administrative expense. There were no material modifications to stock based awards for the years ended December 31, 2013 or 2012, respectively.

Prior to the Spin-Off, we participated in the Amended and Restated Expedia, Inc. 2005 Stock and Annual Incentive Plan, under which we, through Expedia, granted RSUs, stock options, and other stock-based awards to our directors, officers, employees and consultants. At Spin-Off, these existing Expedia stock-based awards were converted into TripAdvisor stock-based equity awards and resulted in approximately 6,575,000 stock options (of which approximately 3,548,000 were fully vested at Spin-Off) and 893,000 RSU’s outstanding. These awards accounted for our 2011 stock-based compensation expense. We will continue to amortize the fair value, net of estimated forfeitures, over the remaining vesting term on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date. All remaining unrecognized stock-based compensation expense related to these awards is included in “Unrecognized Stock-Based Compensation” below.

Stock and Incentive Plan

On December 20, 2011, our 2011 Stock and Annual Incentive Plan became effective. On December 20, 2011, we filed Post-Effective Amendment No. 1 on Form S-8 to Registration Statement on Form S-4 (File No. 333-178637) (the “Prior Registration Statement”) with the Securities and Exchange Commission (the “Commission”), registering a total of 17,500,000 shares of our common stock, of which 17,400,000 shares were issuable in connection with grants of equity-based awards under our 2011 Incentive Plan (7,400,000 of which shares were originally registered on the Form S-4 and 10,000,000 of which shares were first registered on the Prior Registration Statement) and 100,000 shares were issuable under our Deferred Compensation Plan for Non-Employee Directors (refer to “Note 13—Employee Benefit Plans” below for information on our Deferred Compensation Plan for Non-Employee Directors).

At our annual meeting of stockholders held on June 28, 2013 (the “Annual Meeting”), our stockholders approved an amendment to our 2011 Stock and Annual Incentive Plan to, among other things, increase the aggregate number of shares of common stock authorized for issuance thereunder by 15,000,000 shares. We refer to our 2011 Stock and Annual Incentive Plan, as amended by the amendment as the “2011 Incentive Plan.” A summary of the material terms of the 2011 Incentive Plan can be found in “Proposal 3: Approval of the 2011 Stock and Annual Incentive Plan, as amended” in our Proxy Statement for the Annual Meeting.

Pursuant to the 2011 Stock and Annual Incentive Plan, we may, among other things, grant RSUs, restricted stock, stock options and other stock-based awards to our directors, officers, employees and consultants. The summary of the material terms of the 2011 Incentive Plan is qualified in its entirety by the full text of the 2011 Incentive Plan previously filed.

As of December 31, 2013, the total number of shares available under the 2011 Incentive Plan is 18,085,169 shares. All shares of common stock issued in respect of the exercise of options or other equity awards since Spin-Off have been issued from authorized, but unissued common stock.

Stock Based Award Activity and Valuation

2013 Stock Option Activity:

During the year ended December 31, 2013, we have issued 2,824,583 of primarily service based non-qualified stock options under the 2011 Incentive Plan. These stock options generally have a term of ten years from the date of grant and vest over a four-year requisite service period. We will amortize the fair value of the 2013 grants, net of estimated forfeitures, as stock-based compensation expense over the vesting term on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date.

A summary of the status and activity for stock option awards relating to our common stock for the year ended December 31, 2013, is presented below:


	Options Outstanding		Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Life		Aggregate Intrinsic Value
	(In thousands)				(In years)		(In thousands)
Options outstanding at January 1, 2013		8,654	$	31.41
Granted		2,825		58.03
Exercised (1)		1,487		23.81
Cancelled or expired		522		38.09

Options outstanding at December 31, 2013		9,470	$	40.18		5.9	$	403,828

Exercisable as of December 31, 2013		3,533	$	30.11		3.0	$	186,273

Vested and expected to vest after December 31, 2013		8,731	$	39.94		5.7	$	374,487

(1)

Inclusive of 242,767 options which were not converted into shares due to net share settlement in order to cover the aggregate exercise price and the minimum amount of required employee withholding taxes. Potential shares which had been convertible under stock options that were withheld under net share settlement remain in the authorized but unissued pool under the 2011 Incentive Plan and can be reissued by the Company. We began net-share settling the majority of our stock option exercises during the third quarter of 2013. Total payments for the employees’ tax obligations to the taxing authorities due to net share settlements are reflected as a financing activity within the consolidated statements of cash flows.

Aggregate intrinsic value represents the difference between the closing stock price of our common stock and the exercise price of outstanding, in-the-money options. Our closing stock price as reported on NASDAQ as of December 31, 2013 was $82.83. The total intrinsic value of stock options exercised for the years ended December 31, 2013 and 2012 were $58.2 million and $25.1 million, respectively. No stock options were exercised between Spin-Off and December 31, 2011.

The fair value of stock option grants under the 2011 Incentive Plan has been estimated at the date of grant using the Black–Scholes option pricing model with the following weighted average assumptions for the periods presented:


	December 31,
	2013			2012
Risk free interest rate		1.41	%		1.03	%
Expected term (in years)		6.06			6.21
Expected volatility		50.78	%		53.46	%
Expected dividend yield		—	%		—	%

The weighted-average grant date fair value of options granted was $28.30 and $20.36 for the years ended December 31, 2013 and 2012, respectively. No stock options were granted under the 2011 Incentive Plan for the year ended December 31, 2011. The total fair value of stock options vested for the years ended December 31, 2013 and 2012 were $26.6 million and $9.8 million, respectively. No stock options were vested between Spin-Off and December 31, 2011.

2013 RSU Activity:

During the year ended December 31, 2013, we issued 1,148,976 RSUs under the 2011 Incentive Plan for which the fair value was measured based on the quoted price of our common stock. These RSUs generally vest over a four-year requisite service period. We will amortize the fair value of the 2013 grants, net of estimated forfeitures, as stock-based compensation expense over the vesting term on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date.

The following table presents a summary of RSU activity on our common stock during the year ended December 31, 2013:


	RSUs Outstanding		Weighted Average Grant- Date Fair Value Per Share		Aggregate Intrinsic Value
	(In thousands)
Unvested RSUs outstanding as of January 1, 2013		446	$	26.11
Granted		1,149		50.72
Vested and released (1)		363		22.95
Cancelled		97		46.80

Unvested RSUs outstanding as of December 31, 2013		1,135	$	49.64	$	94,125

(1)

Inclusive of 133,449 RSUs withheld to satisfy employee minimum tax withholding requirements due to net share settlement. Potential shares which had been convertible under RSUs that were withheld under net share settlement remain in the authorized but unissued pool under the 2011 Incentive Plan and can be reissued by the Company. Total payments for the employees’ tax obligations to the taxing authorities due to net share settlements are reflected as a financing activity within the consolidated statements of cash flows.

Other Equity Activity:

Upon Spin-Off, we entered into a warrant agreement (the “Warrant Agreement”) with Mellon Investor Services LLC and issued warrants exercisable for TripAdvisor common stock in respect of previously outstanding warrants exercisable for Expedia common stock that were adjusted on account of Expedia’s reverse stock split and the Spin-Off. In total, at Spin-Off, the warrants could have been converted into a maximum of 8,046,698 shares of our common stock without any further adjustments to the Warrant Agreement and had an expiration date of May 7, 2012.

One tranche of warrants (issued in respect of Expedia warrants that had featured an exercise price of $12.23 per warrant prior to adjustment) were exercisable for 0.25 (one-quarter) of a share of TripAdvisor common stock at an exercise price equal to $6.48 per warrant, and the other tranche of warrants (issued in respect of Expedia warrants that had featured an exercise price of $14.45 per warrant prior to adjustment) were exercisable for 0.25 (one-quarter) of a share of TripAdvisor common stock at an exercise price equal to $7.66 per warrant. The exercise price could have been paid in cash or via “cashless exercise” as set forth in the Warrant Agreement.

During the year ended December 31, 2012, and prior to the expiration date, there were a total of 32,186,791 warrants exercised which resulted in a total of 7,952,456 shares of our common stock being issued during that period, which included 31,641,337 warrants for which the exercise price was paid in cash at a weighted average price of $27.11. We received total exercise proceeds of $214.5 million related to these warrant exercises, which is reflected as a financing activity within the consolidated statement of cash flows. In addition there were 545,454 cashless warrants exercised with a weighted average exercise price of $25.92 of which we did not receive any exercise proceeds. As a result, we currently have no outstanding warrants remaining which could be convertible to shares of our common stock.

Unrecognized Stock-Based Compensation

A summary of our remaining unrecognized compensation expense, net of estimated forfeitures, and the weighted average remaining amortization period at December 31, 2013 related to our non-vested stock options and RSU awards is presented below (in thousands, except per year information):


	Stock Options		RSUs
Unrecognized compensation expense (net of forfeitures)	$	93,696	$	33,200

Our cash and cash equivalents consist of cash on hand in global financial institutions, money market funds and marketable securities, with maturities of 90 days or less at the date purchased. The remaining maturities of our long-term marketable securities range from one to three years and our short-term marketable securities include maturities that were greater than 90 days at the date purchased and have 12 months or less remaining at December 31, 2013 and 2012, respectively.

We classify our cash equivalents and marketable securities within Level 1 and Level 2 as we value our cash equivalents and marketable securities using quoted market prices (Level 1) or alternative pricing sources (Level 2). The valuation technique we used to measure the fair value of money market funds were derived from quoted prices in active markets for identical assets or liabilities. Fair values for Level 2 investments are considered “Level 2” valuations because they are obtained from independent pricing sources for identical or comparable instruments, rather than direct observations of quoted prices in active markets. Our procedures include controls to ensure that appropriate fair values are recorded, including comparing the fair values obtained from our independent pricing services against fair values obtained from another independent source.

There were no material realized gains or losses related to sales of our marketable securities for the years ended December 31, 2013, 2012 and 2011.

As of December 31, 2013, we have marketable securities with a total fair value of $168.8 million in a total gross unrealized loss position of $0.3 million. We consider the declines in market value of our marketable securities investment portfolio to be temporary in nature and do not consider any of our investments other-than-temporarily impaired. When evaluating an investment for other-than-temporary impairment, we review factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer and any changes thereto, and the our intent to sell, or whether it is more likely than not we will be required to sell the investment before recovery of the investment’s cost basis. During the years ended December 31, 2013, 2012 and 2011, we did not recognize any impairment charges. We did not have any material investments in marketable securities that were in a continuous unrealized loss position for 12 months or greater at December 31, 2013 or 2012.

Derivative Financial Instruments

In the normal course of business, we are exposed to the impact of foreign currency fluctuations, which we attempt to mitigate through the use of derivative instruments. Accordingly, we have entered into forward contracts to reduce the effects of fluctuating foreign currency exchange rates on our cash flows denominated in foreign currencies. We do not use derivatives for trading or speculative purposes. In accordance with current accounting guidance on derivative instruments and hedging activities, we record all our derivative instruments as either an asset or liability measured at their fair value. Our derivative instruments are typically short-term in nature.

Our current forward contracts are not designated as hedges. Consequently, any gain or loss resulting from the change in fair value is recognized in the current period earnings. These gains or losses are offset by the exposure related to receivables and payables with our foreign subsidiaries. We recorded a net loss of $0.3 million and $0.7 million for the years ended December 31, 2013 and 2012, respectively, related to our forward contracts in our consolidated statements of operations in Other, net. The net cash received or paid related to our derivative instruments are classified as operating in our consolidated statements of cash flows, which is based on the objective of the derivative instruments. No derivative instruments were entered into or settled during the year ended December 31, 2011.

The following table shows the fair value and notional principal amounts of our outstanding or unsettled derivative instruments that are not designated as hedging instruments for the periods presented:

(1)	Current derivative contracts address foreign exchange fluctuations for the Euro versus the U.S. Dollar.

(2)	The fair value of our derivative liability is measured using Level 2 fair value inputs as we use a pricing model that takes into account the contract terms as well as current foreign currency exchange rates in active markets, or observable market inputs.

Concentration of Credit Risk

Counterparties to currency exchange derivatives consist of major international financial institutions. We monitor our positions and the credit ratings of the counterparties involved and, by policy limits, the amount of credit exposure to any one party. While we may be exposed to potential losses due to the credit risk of non-performance by these counterparties, losses are not anticipated.

Other Financial Instruments

Other financial instruments not measured at fair value on a recurring basis include trade receivables, receivables from Expedia, trade payables, deferred merchant payables, short-term debt, accrued and other current liabilities and long-term debt. With the exception of long-term debt, the carrying amount approximates fair value because of the short maturity of these instruments as reported on the consolidated balance sheets as of December 31, 2013 and December 31, 2012. The carrying value of the long-term borrowings outstanding on our Credit Agreement bear interest at a variable rate and therefore is also considered to approximate fair value.

We did not have any Level 3 assets or liabilities at December 31, 2013 or 2012.

Term Loan Facility Due 2016 and Revolving Credit Facility

Overview

On December 20, 2011, we entered into a credit agreement, dated as of December 20, 2011, by and among TripAdvisor, TripAdvisor Holdings, LLC, and TripAdvisor LLC, the lenders party thereto, JPMorgan Chase Bank, N.A., as administrative agent, and J.P. Morgan Europe Limited, as London agent (this credit agreement, together with all exhibits, schedules, annexes, certificates, assignments and related documents contemplated thereby, is referred to herein as the “Credit Agreement”), which provides $600 million of borrowing including:

•

the Term Loan Facility, or Term Loan, in an aggregate principal amount of $400 million with a term of five years due December 2016; and

•

the Revolving Credit Facility in an aggregate principal amount of $200 million available in U.S. dollars, Euros and British pound sterling with a term of five years expiring December 2016.

The Term Loan and any loans under the Revolving Credit Facility bear interest by reference to a base rate or a Eurocurrency rate, in either case plus an applicable margin based on our leverage ratio. We are also required to pay a quarterly commitment fee, on the average daily unused portion of the Revolving Credit Facility for each fiscal quarter and fees in connection with the issuance of letters of credit. The Term Loan and loans under the Revolving Credit Facility currently bear interest at LIBOR plus 150 basis points, or the Eurocurrency Spread, or the alternate base rate (“ABR”) plus 50 basis points, and undrawn amounts are currently subject to a commitment fee of 22.5 basis points. As of December 31, 2013 we are using a one-month interest period Eurocurrency Spread which is approximately 1.7% per annum. Interest is currently payable on a monthly basis while we are borrowing under the one-month interest rate period. The current interest rates are based on current assumptions, leverage and LIBOR rates and do not take into account that rates will reset periodically.

The Term Loan principal is currently repayable in quarterly installments on the last day of each calendar quarter equal to 2.5% of the original principal amount with the balance due on the final maturity date. Principal payments aggregating $40 million were made during the year ended December 31, 2013.

The Revolving Credit Facility includes $40 million of borrowing capacity available for letters of credit and $40 million for borrowings on same-day notice. As of December 31, 2013 there are no outstanding borrowings under our Revolving Credit Facility.

During the years ended December 31, 2013, 2012 and 2011, we recorded total interest and commitment fees on our Credit Agreement of $7.5 million, $8.7 million and $0.3 million, respectively, to interest expense on our consolidated and combined statements of operations. All unpaid interest and commitment fee amounts as of December 31, 2013 and 2012 were not material.

In connection with the Credit Agreement, we also incurred debt financing costs totaling $3.5 million, which were capitalized as deferred financing costs. Approximately $0.7 million, recorded in other current assets, and approximately $ 1.1 million, reported in other long term assets, remain on the consolidated balance sheet as of December 31, 2013, net of amortization. During the years ended December 31, 2013, 2012 and 2011, we recorded amortization expense of $0.8 million, $0.9 million and $0 million, respectively, to interest expense on our consolidated and consolidated statements of operations. These costs will continue to be amortized over the remaining term of the Term Loan using the effective interest rate method.

Total outstanding borrowings under the Credit Agreement consist of the following:

Prepayments

We may voluntarily repay any outstanding borrowing under the Credit Agreement at any time without premium or penalty, other than customary breakage costs with respect to eurocurrency loans.

Guarantees

All obligations under the Credit Agreement are unconditionally guaranteed by us and each of our existing and subsequently acquired or organized direct or indirect wholly-owned domestic and foreign restricted subsidiaries, subject to certain exceptions for subsidiaries that are controlled foreign corporations, foreign subsidiaries in jurisdictions where applicable law would otherwise be violated, and non-material subsidiaries.

Covenants

The Credit Agreement contains a number of covenants that, among other things, restrict our ability to: incur additional indebtedness, create liens, enter into sale and leaseback transactions, engage in mergers or consolidations, sell or transfer assets, pay dividends and distributions, make investments, loans or advances, prepay certain subordinated indebtedness, make certain acquisitions, engage in certain transactions with affiliates, amend material agreements governing certain subordinated indebtedness, and change our fiscal year. The Credit Agreement also requires us to maintain a maximum leverage ratio and a minimum cash interest coverage ratio, and contains certain customary affirmative covenants and events of default, including a change of control. If an event of default occurs, the lenders under the Credit Agreement will be entitled to take various actions, including the acceleration of all amounts due under Credit Agreement and all actions permitted to be taken by a secured creditor.

As of December 31, 2013 we believe we are in compliance with all of our debt covenants.

Chinese Credit Facilities

In addition to our borrowings under the Credit Agreement, we maintain our Chinese Credit Facilities. As of December 31, 2013 and December 31, 2012, we had short-term borrowings outstanding of $28.5 million and $32.1 million, respectively.

Certain of our Chinese subsidiaries entered into a RMB 138,600,000 (approximately $22 million), one-year revolving credit facility with Bank of America (the “Chinese Credit Facility—BOA”) that is currently subject to review on a periodic basis with no-specific expiration period. During the third quarter of 2012, this credit line was increased to RMB 189,000,000 (approximately $30 million). During the year ended December 31, 2013, we made a payment inclusive of interest of RMB 68,283,570 (approximately $10.9 million). We currently have $12.7 million of outstanding borrowings from the Chinese Credit Facility—BOA as of December 31, 2013. Our Chinese Credit Facility—BOA currently bears interest at a rate based on 100% of the People’s Bank of China’s base rate and was 5.6% as of December 31, 2013.

In addition, during April 2012, certain of our Chinese subsidiaries entered into a RMB 125,000,000 (approximately $20 million) one-year revolving credit facility with J.P. Morgan Chase Bank (“Chinese Credit Facility-JPM”). This credit facility was renewed for an additional year in April 2013. During the year ended December 31, 2013, we made a payment inclusive of interest of RMB 24,281,546 (approximately $3.9 million). We currently have $15.8 million of outstanding borrowings from the Chinese Credit Facility—JPM as of December 31, 2013. Our Chinese Credit Facility—JPM currently bears interest at a rate based on 100% of the People’s Bank of China’s base rate and was 5.6% as of December 31, 2013.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

For all periods presented, current and deferred tax expense has been computed using our stand-alone effective rate. As of December 31, 2013, our current income tax receivable and income tax payable balances represent amounts that we will receive and pay, respectively, to the Internal Revenue Service and other tax authorities.

For all periods prior to and through the Spin-Off date, we were a member of the Expedia consolidated tax group. Accordingly, Expedia filed a consolidated federal income tax return and certain state income tax returns with us for that period. Expedia has paid the entire income tax liability associated with these filings. As such, our income tax liability for this period was transferred to Expedia upon Spin-Off and was not included in income taxes payable as of December 31, 2011. Additionally, due to continuing ownership and business relationships after the Spin-Off, we have filed as part of a unitary combined group with Expedia for certain state tax returns for the 2012 and 2011 tax years. During 2013, we plan to file our state tax returns on a stand-alone basis, separate from Expedia, as our ownership and business relationships likely will not constitute a unitary relationship after 2012.

Our deferred tax assets and deferred tax liabilities as of December 31, 2013 and 2012 are as follows:

At December 31, 2013, we had federal, state and foreign net operating loss carryforwards (“NOLs”) of approximately $ 12.5 million, $12.4 million and $51.0 million. If not utilized, the federal and state NOLs will expire at various times between 2020 and 2033 and the foreign NOLs will expire at various times between 2013 and 2031.

At December 31, 2013, we had a valuation allowance of $13.3 million primarily related to foreign net operating loss carryforwards for which it is more likely than not that the tax benefit will not be realized. This amount represented an overall increase of $1.6 million over the amount recorded as of December 31, 2012.

We have not provided for deferred U.S. income taxes on undistributed earnings of our foreign subsidiaries that we intend to reinvest permanently outside the United States; the total amount of such earnings as of December 31, 2013 was $481.0 million. Should we distribute or be treated under certain U.S. tax rules as having distributed earnings of foreign subsidiaries in the form of dividends or otherwise, we may be subject to U.S. income taxes. Due to complexities in tax laws and various assumptions that would have to be made, it is not practicable at this time to estimate the amount of unrecognized deferred U.S. taxes on these earnings.

A reconciliation of the provision for income taxes to the amounts computed by applying the statutory federal income tax rate to income before income taxes is as follows:


	Year Ended December 31,
	2013			2012			2011
	(In thousands)

During the fourth quarter of 2012, we restructured our non-U.S. operations to align our global structure for more efficient treasury management and global cash deployment. As a result, and due to the continued expansion of our non-U.S. operations, we expect our effective tax rate to continue to decrease.

During 2011, the Singapore Economic Development Board accepted our application to receive a tax incentive under the International Headquarters Award. This incentive provides for a reduced tax rate on qualifying income of 5% as compared to Singapore’s statutory tax rate of 17% and is conditional upon our meeting certain employment and investment thresholds. This agreement is set to expire on June 30, 2016, with the ability to extend for another five years. This benefit resulted in a decrease to the 2013 tax provision of $4.3 million.

By virtue of previously filed consolidated income tax returns filed with Expedia, we are routinely under audit by federal, state and foreign tax authorities. We are currently under an IRS audit for the 2009 and 2010 tax years, and have various ongoing state income tax audits. As of December 31, 2013, no material assessments have resulted from these audits. These audits include questioning the timing and the amount of income and deductions and the allocation of income among various tax jurisdictions. Annual tax provisions include amounts considered sufficient to pay assessments that may result from the examination of prior year returns. We are no longer subject to tax examinations by tax authorities for years prior to 2007.

A reconciliation of the beginning and ending amount of gross unrecognized tax benefits (excluding interest and penalties) is as follows:


	December 31,
	2013			2012			2011
	(In thousands)
Balance, beginning of year	$	24,049		$	12,900		$	6,342

Balance, end of year	$	36,427		$	24,049		$	12,900

As of December 31, 2013, we had $36.4 million of unrecognized tax benefits, which is classified as long-term and included in other long-term liabilities. Included in this balance at December 31, 2013 was $19.0 million of liabilities for uncertain tax positions that, if recognized, would decrease our provision for income taxes. We recognize interest and penalties related to unrecognized tax benefits in income tax expense. As of December 31, 2013 and 2012, total gross interest and penalties accrued was $1.7 million and $1.0 million, respectively.

Commitments And Contingencies Disclosure [Abstract]

Commitments and Contingencies

NOTE 12: COMMITMENTS AND CONTINGENCIES

We have commitments and obligations that include office space leases, vendor purchase obligations and expected interest on long-term debt, which are not accrued on the consolidated balance sheet at December 31, 2013 but we expect to require future cash outflows and in some cases may be accelerated upon demand of a third party upon certain contingent events.

Office Lease Commitments

We have contractual obligations in the form of operating leases for office space for which we record the related expense on a monthly basis. Certain leases contain periodic rent escalation adjustments and renewal options. Rent expense related to such leases is recorded on a straight-line basis. Operating lease obligations expire at various dates with the latest maturity in December 2030. For the years ended December 31, 2013, 2012 and 2011, we recorded rental expense of $10.9 million, $7.8 million and $6.0 million, respectively.

We currently lease approximately 119,000 square feet for our corporate headquarters in Newton, Massachusetts, pursuant to a lease with an expiration date of April 2015. We also lease an aggregate of approximately 382,000 square feet at approximately 30 other locations across North America, Europe and Asia Pacific, primarily for our international management teams, sales offices, and subsidiary headquarters, pursuant to leases with expiration dates through December 2030.

In June 2013, TripAdvisor LLC (“TA LLC”), our indirect, wholly owned subsidiary, entered into a lease (the “Lease”), for a new corporate headquarters. Pursuant to the Lease, the landlord will build an approximately 280,000 square foot rental building in Needham, Massachusetts (the “Premises”), and thereafter lease the Premises to TA LLC as TripAdvisor’s new corporate headquarters for an initial term of 15 years and 7 months. If the landlord fails to deliver the Premises according to the schedule, subject to certain conditions, TA LLC may be entitled to additional free rent, or in extreme cases, a right to terminate the Lease. Under the Lease, TA LLC is required to pay an initial base rent of $33.00 per square foot per year, increasing to $34.50 per square foot by the final year of the initial term, as well as all real estate taxes and other building operating costs. TA LLC also has an option to extend the term of the Lease for two consecutive terms of five years each.

The aggregate future minimum lease payments are $143.5 million and are currently scheduled to be paid, beginning in November 2015, as follows: $1.1 million for 2015, $9.3 million for 2016, $9.3 million for 2017, $9.3 million for 2018 and $114.6 million for 2019 and thereafter. The Lease has escalating rental payments and initial periods of free rent. TA LLC was also obligated to deliver a letter of credit to the Landlord in the amount of $0.8 million as security deposit, which amount is subject to increase under certain circumstances. TA LLC also has an option to extend the term of the Lease for two consecutive terms of five years each. Subject to certain conditions, TA LLC has certain rights under the Lease, including rights of first offer to lease additional space or to purchase the Premises if the Landlord elects to sell. In connection with the Lease, TripAdvisor entered into a Guaranty (the “Guaranty”), pursuant to which TripAdvisor provides full payment and performance guaranty for all of TA LLC’s obligations under the Lease.

We have concluded we are the deemed owner (for accounting purposes only) of the Premises during the construction period under build to suit lease accounting. As building construction began in the fourth quarter of 2013, we recorded estimated project construction costs incurred by the landlord as an asset and a corresponding long term liability in “Property and equipment, net” and “Other long-term liabilities,” respectively, on our consolidated balance sheets. We will increase the asset and corresponding long term liability as additional building costs are incurred by the landlord during the construction period.

Once the landlord completes the construction of the Premises (estimated to be May 2015), we will evaluate the Lease in order to determine whether or not the Lease meets the criteria for “sale-leaseback” treatment. If the Lease meets the “sale-leaseback” criteria, we will remove the asset and the related liability from its consolidated balance sheet and treat the Lease as either an operating or capital lease based on the our assessment of the accounting guidance.

If the Lease does not meet “sale-leaseback” criteria, we will treat the Lease as a financing obligation and lease payments will be attributed to (1) a reduction of the principal financing obligation; (2) imputed interest expense; and (3) land lease expense (which is considered an operating lease) representing an imputed cost to lease the underlying land of the facility. In addition, the underlying building asset will be depreciated over the building’s estimated useful life. And at the conclusion of the lease term, we would de-recognize both the net book values of the asset and financing obligation. Although we will not begin making lease payments pursuant to the Lease until November 2015, the portion of the lease obligations allocated to the land is treated for accounting purposes as an operating lease that commenced in 2013.

Purchase Obligations

As of December 31, 2013, we had minimum non-cancelable purchase obligations with certain of our vendors, which we expect to utilize in the ordinary course of business. The expected timing and payment amounts are listed in the table below.

The following table summarizes our material commitments and obligations as of December 31, 2013 and excludes amounts already recorded on the consolidated balance sheet:


			By Period
	Total		Less than 1 year		1 to 3 years		3 to 5 years		More than 5 years
	(In thousands)

(1)	Estimated future minimum rental payments under operating leases with non-cancelable lease terms.

(2)	Estimated future minimum rental payments for our future corporate headquarters in Needham, MA.

(3)

The amounts included as expected interest payments on the Term Loan in this table are based on the current effective interest rate and payment terms as of December 31, 2013, but, could change significantly in the future. Amounts assume that our existing debt is repaid at maturity and do not assume additional borrowings or refinancings of existing debt. Refer to “Note 8—Debt” above for additional information, including principal payments expected to be paid over the next three years, on our Term Loan.

(4)

Excluded from the table was $38 million of unrecognized tax benefits, including interest and penalties, that we have recorded in other long-term liabilities for which we cannot make a reasonably reliable estimate of the amount and period of payment. We estimate that none of these amounts will be paid within the next twelve months.

(5)

In connection with the Spin-Off, we assumed Expedia’s obligation to fund a charitable foundation. The Board of Directors of the charitable foundation is currently comprised of Stephen Kaufer- President and Chief Executive Officer, Julie M.B. Bradley-Chief Financial Officer and Seth J. Kalvert- Senior Vice President, General Counsel and Secretary. Our obligation was calculated at 2.0% of OIBA in 2013. For a discussion regarding OIBA see “Note 16—Segment Information” in the notes to the consolidated and combined financial statements. This future commitment has been excluded from the table above.

(6)

Excludes spending on anticipated leasehold improvements on our Needham, Massachusetts lease, including design, development, construction costs, and the purchase and installation of equipment, net of related Landlord incentives, which we estimate will begin in the fourth quarter of 2014 thru the second quarter of 2015 and currently estimate will cost in the range of $35-$40 million.

Letters of Credit

As of December 31, 2013, we have issued unused letters of credit totaling $1 million, related to our property leases.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of Regulation S-K of the SEC, that have, or are reasonably likely to have, a current or future effect on our financial condition, results of operations, liquidity, capital expenditures or capital resources at December 31, 2013.

Legal Proceedings

In the ordinary course of business, we and our subsidiaries are parties to legal proceedings and claims involving alleged infringement of third-party intellectual property rights, defamation, and other claims. Rules of the SEC require the description of material pending legal proceedings, other than ordinary, routine litigation incident to the registrant’s business, and advise that proceedings ordinarily need not be described if they primarily involve damages claims for amounts (exclusive of interest and costs) not individually exceeding 10% of the current assets of the registrant and its subsidiaries on a consolidated basis. In the judgment of management, none of the pending litigation matters that the Company and its subsidiaries are defending involves or is likely to involve amounts of that magnitude. There may be claims or actions pending or threatened against us of which we are currently not aware and the ultimate disposition of which could have a material adverse effect on us.

The entire disclosure for commitments and contingencies.

Employee Benefit Plans	12 Months Ended
Employee Benefit Plans	Dec. 31, 2013
Compensation And Retirement Disclosure [Abstract]
Employee Benefit Plans	NOTE 13: EMPLOYEE BENEFIT PLANS *Expedia 401(k) Plan* Our U.S. employees were generally eligible to participate in Expedia’s retirement and savings plan (the “Expedia 401(k) Plan”) that qualified under Section 401(k) of the Internal Revenue Code until October 31, 2011. Our employees ceased to participate in the Expedia 401(k) Plan after our retirement savings plan was established on November 1, 2011 as described below. Within the Expedia 401(k) Plan, participating employees could contribute up to 50% of their pretax salary, but not more than statutory limits. We matched 50% of the first 6% of employee contributions to the plan for a maximum employer contribution of 3% of a participant’s eligible earnings. Our employer matching contributions vested after two years of continuous service. Participating employees had the option to invest in Expedia’s common stock, but there was no requirement for participating employees to invest their contribution or our matching contribution in Expedia’s common stock. Expedia also had various defined contribution plans for our international employees. Contributions to these benefit plans for our employees were $2 million for the year ended December 31, 2011, respectively. *TripAdvisor Retirement Savings Plan* Effective November 1, 2011, most of our U.S. employees were eligible to participate in a new retirement and savings plan, the TripAdvisor Retirement Savings Plan (the “401(k) Plan”), that qualifies under Section 401(k) of the Internal Revenue Code. The 401(k) Plan is similar to and replaced the Expedia 401(k) Plan, allowing participating employees to make contributions of a specified percentage of their eligible compensation. Participating employees may contribute up to 50% of their eligible salary on a pre-tax basis, but not more than statutory limits. Employee-participants age 50 and over may also contribute an additional amount of their salary on a pre-tax tax basis up to the IRS Catch-Up Provision Limit. Employees may also contribute into the 401(k) Plan on an after-tax basis up to an annual maximum of 10%. The 401(k) Plan has an automatic enrollment feature at 3% pre-tax. We match 50% of the first 6% of employee contributions to the plan for a maximum employer contribution of 3% of a participant’s eligible earnings. The “catch up contributions”, are not eligible for employer matching contributions. The matching contributions portion of an employee’s account, vests after two years of service. Effective June 8, 2012 the 401(k) Plan permits certain after-tax Roth 401(k) contributions. Additionally, at the end of the 401 (k) Plan year, we make a discretionary matching contribution to eligible participants. This additional discretionary matching employer contribution referred to as “true up” is limited to match only contributions up to 3% of eligible compensation. Our employee’s interests were rolled into the 401(k) Plan from the Expedia 401(k) Plan in connection with the creation of our new plan on November 1, 2011. We also have various defined contribution plans for our international employees. Our contribution to the 401(k) Plan and our international defined contribution plans was not material for the period from November 1, 2011 through December 31, 2011 and $4.8 million and $3.1 million for the years ended December 31, 2013 and 2012, respectively. *TripAdvisor, Inc. Deferred Compensation Plan for Non-Employee Directors* On December 20, 2011, the TripAdvisor, Inc. Deferred Compensation Plan for Non-Employee Directors (the “Plan”) became effective. Under the Plan, eligible directors who defer their directors’ fees may elect to have such deferred fees (i) applied to the purchase of share units, representing the number of shares of our common stock that could have been purchased on the date such fees would otherwise be payable, or (ii) credited to a cash fund. The cash fund will be credited with interest at an annual rate equal to the weighted average prime or base lending rate of a financial institution selected in accordance with the terms of the Plan and applicable law. Upon termination of service as a director of TripAdvisor, a director will receive (i) with respect to share units, such number of shares of our common stock as the share units represent, and (ii) with respect to the cash fund, a cash payment. Payments upon termination will be made in either one lump sum or up to five annual installments, as elected by the eligible director at the time of the deferral election. Under the 2011 Incentive Plan, 100,000 shares of TripAdvisor common stock are available for issuance to non-employee directors. There have been no shares of common stock issued from the inception of the Plan through December 31, 2013.

Class B common stockholders may, at any time, convert their shares into common stock, on a one for one share basis. Upon conversion, the Class B common stock is retired and is not available for reissue. In the event of liquidation, dissolution, distribution of assets or winding-up of TripAdvisor the holders of both classes of common stock have equal rights to receive all the assets of TripAdvisor after the rights of the

holders of the preferred stock have been satisfied. There were 131,537,798 and 129,417,089 shares of common stock issued and outstanding, respectively, at December 31, 2013 and 12,799,999 shares of Class B common stock issued and outstanding at December 31, 2013.

On February 15, 2013, our Board of Directors authorized the repurchase of $250 million of our shares of common stock under a share repurchase program. We intend to use available cash and future cash from operations to fund repurchases under the share repurchase program.

Related Party Transactions	12 Months Ended
Related Party Transactions	Dec. 31, 2013
Related Party Transactions [Abstract]
Related Party Transactions	NOTE 15: RELATED PARTY TRANSACTIONS *Relationship between Expedia and TripAdvisor* Upon consummation of the Spin-Off, Expedia was considered a related party under GAAP based on a number of factors, including, among others, common ownership of our shares and those of Expedia. A number of those factors no longer exist; as a result, we no longer consider Expedia a related party however, due to the importance of our relationship with Expedia, for purposes of these financial statements for the year ended December 31, 2013, we have continued to list separately in our consolidated and combined financial statements revenue and receivables from Expedia. Revenue from Expedia was $217.4 million, 203.8 million and $211.0 million for the years ended December 31, 2013, 2012 and 2011, respectively, which primarily consists of click-based advertising and other advertising services provided to Expedia and its subsidiaries and is recorded at contract value, which we believe is a reasonable reflection of the value of the services provided. Revenue represented 23%, 27% and 33% of our total revenue for the years ended December 31, 2013, 2012 and 2011, respectively. Other operating expenses which were included primarily within selling and marketing expense were $6.0 million, $6.4 million, and $4.3 million for the years ended December 31, 2013, 2012 and 2011, respectively, primarily consisted of marketing expense for exit windows. The receivable balances with Expedia reflected in our consolidated balance sheets as of December 31, 2013 and December 31, 2012 were $15.8 million and $24.0 million, respectively. Prior to the Spin-Off, our operating expenses included a shared services fee, which was $9.2 million for the year ended December 31, 2011, which was comprised of allocations from Expedia for accounting, legal, tax, corporate development, financial reporting, treasury and real estate functions and included an allocation of employee compensation within these functions. These allocations were determined on a basis that Expedia and we considered to be a reasonable reflection of the cost of services provided or the benefit received by us. These expenses were allocated based on a number of factors including headcount, estimated time spent and operating expenses. It was not practicable to determine the amounts of these expenses that would have been incurred had we operated as an unaffiliated entity. In the opinion of our management, the allocation method was reasonable. We transferred $405.5 million in cash to Expedia in the form of a dividend, prior to completion of the Spin-Off. Per the Separation Agreement we were to retain $165 million in cash on hand immediately following the Spin-off and the agreement also provided for a subsequent reconciliation process to ensure the appropriate amount was retained. The completion of this reconciliation resulted in us recording an additional receivable from Expedia of $7 million at December 31, 2011, which was subsequently received by us during 2012. For purposes of governing certain of the ongoing relationships between us and Expedia at and after the Spin-Off, and to provide for an orderly transition, we and Expedia entered into various agreements, including, among others, the Separation Agreement, the Tax Sharing Agreement, the Employee Matters Agreement and Transition Services Agreement, and commercial agreements. The full texts of the Separation Agreement, the Tax Sharing Agreement, the Employee Matters Agreement and the Transition Services Agreement are incorporated by reference in this Annual Report on Form 10-K as Exhibits 2.1, 10.2, 10.3 and 10.4. TripAdvisor has satisfied its obligations under the Separation Agreement, the Employee Matters Agreement and the Transition Services Agreement. TripAdvisor continues to be subject to certain post-spin obligations under the Tax Sharing Agreement. *Relationship between Liberty and TripAdvisor* On December 11, 2012, Liberty Interactive Corporation, or Liberty, purchased an aggregate of 4,799,848 shares of common stock of TripAdvisor from Barry Diller, our former Chairman of the Board of Directors and Senior Executive, and certain of his affiliates (the “Stock Purchase”). As of December 31, 2013, Liberty beneficially owned 18,159,752 shares of our common stock and 12,799,999 shares of our Class B common stock, which shares constitute 14.0% of the outstanding shares of Common Stock and 100% of the outstanding shares of Class B Common Stock. Assuming the conversion of all of the Liberty’s shares of Class B common stock into common stock, Liberty would beneficially own 21.8% of the outstanding common stock (calculated in accordance with Rule 13d-3). Because each share of Class B common stock generally is entitled to ten votes per share and each share of common stock is entitled to one vote per share, Liberty may be deemed to beneficially own equity securities representing approximately 56.8% of our voting power. We had no other material related party transactions with Liberty during the years ended December 31, 2013, 2012 or 2011.

Segment Reporting [Abstract]

NOTE 16: SEGMENT AND GEOGRAPHIC INFORMATION

Segment Information

We have one operating and reportable segment: TripAdvisor. We determined our segment based on how our chief operating decision maker manages our business, makes operating decisions, evaluates operating performance and allocates resources. The chief operating decision maker for the Company is our Chief Executive Officer.

Our primary operating metric for evaluating segment performance is Adjusted EBITDA. We define Adjusted EBITDA as net income (loss) plus: (1) provision for income taxes; (2) other (income) expense, net; (3) depreciation of property and equipment, including internal use software and website development; (4) amortization of intangible assets; (5) stock-based compensation; and (6) non-recurring expenses. Such amounts are detailed in our segment reconciliation below. In addition, please see our discussion of Adjusted EBITDA in the section of this Annual Report on Form 10-K entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

The following table is a reconciliation of Adjusted EBITDA to net income, the most directly comparable financial measure calculated and presented in accordance with GAAP, for the periods presented:

(2)

We define OIBA as net income (loss) plus: (1) provision for income taxes; (2) other (income) expense, net; (3) amortization of intangible assets; (4) stock-based compensation; and (5) non-recurring expenses. This operating metric is only used by our management to calculate our annual obligation for our charitable foundation. Refer to “Note 12—Commitments and Contingencies” above for a discussion of our charitable foundation.

Revenue and Geographic Information

We derive substantially all of our revenue from the sale of advertising, primarily through click-based advertising and, to a lesser extent, display-based advertising.

Description of Business

Description of Business

TripAdvisor is an online travel company, empowering users to plan and have the perfect trip. TripAdvisor’s travel research platform aggregates reviews and opinions of members about destinations, accommodations (hotels, B&Bs, specialty lodging and vacation rentals), restaurants and activities throughout the world through our flagship TripAdvisor brand. TripAdvisor-branded websites include tripadvisor.com in the United States and localized versions of the website in 33 countries, including in China under the brand daodao.com. Beyond travel-related content, TripAdvisor websites also include links to the websites of our travel advertisers allowing travelers to directly book their travel arrangements. In addition to the flagship TripAdvisor brand, we manage and operate 20 other travel brands, connected by the common goal of providing comprehensive travel planning resources across the travel sector. We derive substantially all of our revenue from advertising, primarily through click-based advertising and display-based advertising sales. In addition, we earn revenue through a combination of subscription-based offerings from our Business Listings and Vacation Rental products, transaction revenue from making hotel room nights available for booking on our transactional sites, and other revenue including licensing our content to third-parties. We have one operating and reportable segment: TripAdvisor. The segment is determined based on how our chief operating decision maker manages our business, makes operating decisions and evaluates operating performance.

Seasonality

Seasonality

Expenditures by travel advertisers tend to be seasonal. Traditionally, our strongest quarter has been the third quarter, which is a key travel research period, with the weakest quarter being the fourth quarter. However, adverse economic conditions or continued growth of our international operations with differing holiday peaks may influence the typical trend of our seasonality in the future.
