NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: ORGANIZATION AND BASIS OF PRESENTATION

We refer to TripAdvisor, Inc. and our wholly-owned subsidiaries as “TripAdvisor,” “the Company,” “us,” “we” and “our” in these notes to the unaudited consolidated 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.

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 (including hotels, bed and breakfasts, 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 media brands: www.airfarewatchdog.com, www.bookingbuddy.com, www.cruisecritic.com, www.everytrail.com, www.familyvacationcritic.com, www.flipkey.com, www.gateguru.com, www.holidaylettings.co.uk, www.holidaywatchdog.com, www.independenttraveler.com, www.jetsetter.com, www.niumba.com, www.onetime.com, www.seatguru.com, www.smartertravel.com, www.tingo.com, www.travelpod.com, www.virtualtourist.com, www.whereivebeen.com, and www.kuxun.cn, 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 selling room nights on our transactional sites, and other revenue including licensing our content to third-parties. We have one 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.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared by us in accordance with generally accepted accounting principles, or GAAP, for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in financial statements prepared under generally accepted accounting principles for complete periods have been condensed or omitted pursuant to such regulations. In the opinion of management, all adjustments considered necessary for a fair presentation of our financial position, results of operations and cash flows have been included. All such adjustments are of a normal recurring nature. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2012 in our Annual Report on Form 10-K. The results for interim periods are not necessarily indicative of the results to be expected for the full year. The financial statements and related financial disclosures have been presented on a consolidated basis.

Consolidation

Our consolidated financial statements include the accounts of 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 noncontrolling interest in our consolidated financial statements to recognize the minority ownership interest in our consolidated subsidiaries. Noncontrolling interest in the earnings and losses of consolidated subsidiaries represent the share of net income or loss allocated to members or partners in our consolidated entities. Significant intercompany transactions between the TripAdvisor consolidated entities and accounts have been eliminated.

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. Although we currently operate at a loss in the Chinese market, our variable interest entities are not material for all periods presented.

8

Accounting Estimates

We use estimates and assumptions in the preparation of our consolidated 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 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 financial statements include revenue recognition; recoverability of long-lived assets, valuation and impairment of marketable securities, intangible assets and goodwill; income taxes; useful lives of property and equipment; purchase accounting and stock-based compensation.

Reclassifications

We have reclassified certain amounts related to our prior period results to conform to our current period presentation.

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.

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES

Deferred Merchant Payables

We receive cash from travelers at the time of booking related to our 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 September 30, 2013, our deferred merchant payables balance was $28.6 million and for the nine months ended September 30, 2013, the related transactions generated positive operating cash flow of $12.8 million. A payable balance of $14.5 million was acquired with our business acquisitions during the nine months ended September 30, 2013. For additional information on our business acquisitions refer to “Note 6—Acquisitions” below. The deferred merchant payables balance at December 31, 2012 was $1.3 million.

There have been no material changes or other additions to our significant accounting policies since December 31, 2012. For additional information about our critical accounting policies and estimates, refer to “Note 2—Significant Accounting Policies,” included in our Annual Report on Form 10-K for the year ended December 31, 2012.

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 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 financial statements or related disclosures.

Stock-based compensation expense relates primarily to expense for restricted stock units (“RSUs”) and stock options. Our outstanding RSUs and stock options generally vest over four years.

For the three and nine months ended September 30, 2013, we recognized total stock-based compensation expense of $11.7 million and $35.5 million, respectively. The total income tax benefit related to stock-based compensation expense was $4.4 million and $13.8 million for the three and nine months ended September 30, 2013, respectively. For the three and nine months ended September 30, 2012, we recognized total stock-based compensation expense of $8.5 million and $19.9 million, respectively. The total income tax benefit related to stock-based compensation expense was $3.2 million and $7.2 million for the three and nine months ended September 30, 2012, respectively.

TripAdvisor, Inc. 2011 Stock and Annual Incentive Plan, As Amended

On December 20, 2011, our 2011 Stock and Annual Incentive Plan became effective. 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. 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.

2013 Stock Option Activity

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. Stock options granted during the first nine months of 2013 generally have a term of ten years from the date of grant and generally vest over a four-year service period.

During the nine months ended September 30, 2013, we granted 2,776,247 primarily service-based stock options under the 2011 Incentive Plan with a weighted average grant-date fair value per option of $28.11. We will amortize the fair value, 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. We use historical data to estimate pre-vesting option 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.

A summary of the status and activity for stock option awards relating to our common stock for the nine months ended September 30, 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		2,776		57.66
Exercised (1)		1,273		23.53			$	45,300
Cancelled		481		37.34
Options outstanding at September 30, 2013		9,676	$	39.69		6.1	$	349,716
Exercisable as of September 30, 2013		3,499	$	29.83		3.2	$	160,963
Vested and expected to vest after September 30, 2013		8,813	$	39.46		5.9	$	320,645

(1) Inclusive of 168,795 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 September 30, 2013 was $75.84.

The estimated fair value of the options granted under the 2011 Incentive Plan was 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 estimated the 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 of a peer group was based upon the relatively short period of availability of data on our common stock. We estimated 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.

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

	Three months ended September 30,						Nine months ended September 30,
	2013			2012			2013			2012
Risk free interest rate		1.83	%		0.90	%		1.40	%		1.03	%
Expected term (in years)		5.80			6.25			6.05			6.22
Expected volatility		49.62	%		54.78	%		50.81	%		53.54	%
Expected dividend yield		0	%		0	%		0	%		0	%

2013 RSU Activity

During the nine months ended September 30, 2013, we granted 1,083,082 primarily service-based RSUs under the 2011 Incentive Plan for which the fair value was measured based on the quoted price of our common stock at the date of grant. We will amortize the fair value, 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.

The following table presents a summary of RSU activity on our common stock:

	RSUs Outstanding		Weighted Average Grant- Date Fair Value Per Share		Aggregate Intrinsic Value
	(In thousands)				(In thousands)
Unvested RSUs outstanding as of January 1, 2013		446	$	26.11
Granted		1,083		48.84
Vested and released (1)		333		22.51
Cancelled		76		44.81
Unvested RSUs outstanding as of September 30, 2013		1,120	$	47.27	$	84,989

(1) Inclusive of 127,199 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.

A summary of the unrecognized compensation expense, net of estimated forfeitures, and the weighted average period remaining at September 30, 2013 related to our non-vested stock options and RSU awards is presented below (in thousands, except year information):

	Stock Options		RSUs
Unrecognized compensation expense (net of forfeitures)	$	100,509	$	32,061
Weighted average period remaining (in years)		3.46		3.29

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.

(1) Total cash does not include $40.4 million of marketable securities which were sold during the period, but had not yet settled on report date. This amount was recorded to Receivable—sale of marketable securities on our consolidated balance sheet at September 30, 2013. This cash was received on October 1, 2013.

12

Our cash and cash equivalents consist of cash on hand in global financial institutions, money market funds and marketable securities with contractual maturity dates of 90 days or less at the date purchased. The remaining contractual maturity dates of our long-term marketable securities range from one to three years and our short-term marketable securities include contractual maturity dates that were greater than 90 days at the date purchased and have 12 months or less remaining at September 30, 2013.

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 was derived from quoted prices in active markets for identical assets or liabilities. Investments in U.S. Treasury securities are considered “Level 2” valuations because we have access to quoted prices, but do not have visibility into the volume and frequency of trading for all investments. Fair values for our U.S. agency securities, commercial paper, corporate securities, certificates of deposit and municipal securities are considered “Level 2” valuations because they are obtained from pricing sources for identical or comparable instruments, rather than direct observations of quoted prices in active markets.

There were no material realized gains or losses related to sales of our marketable securities for the three and nine months ended September 30, 2013 and 2012.

As of September 30, 2013, we have marketable securities with a total fair value of $165.1 million in a total gross unrealized loss position of $0.4 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 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 nine months ended September 30, 2013 and 2012, we did not recognize any impairment charges. We did not have any investments in marketable securities that were in a continuous unrealized loss position for 12 months or greater at September 30, 2013 or December 31, 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 $1.2 million and $0.6 million for the three and nine month periods ended September 30, 2013, respectively, related to our forward contracts in our consolidated statement of operations in Other, net. We recorded a net loss of $0.3 million for the three and nine month periods ended September 30, 2012, respectively, related to our forward contracts in our consolidated statement 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.

The following tables show the fair value and notional principal amounts of our outstanding or unsettled derivative instruments that are not designated as hedging instruments (in thousands):

	Balance Sheet Caption	September 30, 2013

		Asset		Liability
Foreign exchange-forward contracts (current)	Accrued and other current liabilities (1)	$	—	$	64	$	2,710

(1) Derivative contracts address foreign exchange fluctuations for the Euro versus the U.S. dollar.

(2) The fair value of our derivatives are 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.

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, related party receivables, 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 our consolidated balance sheets as of September 30, 2013 and December 31, 2012. The carrying value of the long-term borrowings outstanding on our Credit Agreement bears interest at a variable rate and therefore is also considered to approximate fair value.

We did not have any Level 3 assets or liabilities for the periods ended September 30, 2013 and December 31, 2012.

NOTE 5: DEBT

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.

14

As of September 30, 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 $30 million were made during the nine months ended September 30, 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 September 30, 2013, there are no outstanding borrowings under our Revolving Credit Facility. During the three and nine months ended September 30, 2013, we recorded total interest and commitment fees on our Credit Agreement of $1.8 million and $5.9 million, respectively, to interest expense, on our consolidated statement of operations. During the three and nine months ended September 30, 2012, we recorded total interest and commitment fees on our Credit Agreement of $2.1 million and $6.5 million, respectively, to interest expense on our consolidated statements of operations. All unpaid interest and commitment fee amounts as of September 30, 2013 and December 31, 2012 were not material.

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.

15

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 September 30, 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 September 30, 2013 and December 31, 2012, we had short-term borrowings outstanding of $26.2 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 nine months ended September 30, 2013, we made a payment inclusive of interest of RMB 68,283,570 (approximately $10.9 million). We currently have $11.9 million of outstanding borrowings from the Chinese Credit Facility—BOA as of September 30, 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 September 30, 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 nine months ended September 30, 2013, we made a payment inclusive of interest of RMB 24,281,546 (approximately $3.9 million). We currently have $14.3 million of outstanding borrowings from the Chinese Credit Facility—JPM as of September 30, 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 September 30, 2013.

NOTE 6: ACQUISITIONS

During the nine months ended September 30, 2013, we completed five acquisitions for total cash consideration paid of $31.5 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; and GateGuru, a mobile app with flight and airport information around the world, 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. Acquisition-related costs were expensed as incurred and were not significant.

The following table presents the summary purchase price allocation initially recorded for all 2013 acquisitions on our consolidated balance sheets at the respective acquisition dates (in thousands):

	Total
Net liabilities (1)	$	(14,195	)
Goodwill (2)		34,137
Intangible assets (3)		16,944
Deferred tax liability		(1,352	)
Total purchase price consideration (4)	$	35,534

(1) Includes cash acquired of $2.9 million.

(2) 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 $17.4 million is expected to be deductible for tax purposes.

(3) Identifiable definite-lived intangible assets were comprised of developed technology of $1.6 million, trade names of $7.0 million, customer relationships of $7.9 million, and non-compete agreements of $0.4 million. The overall weighted-average life of the identifiable definite-lived intangible assets acquired in the purchase of the companies was 8.3 years, which will be amortized on a straight-line basis over their estimated useful lives from acquisition date.

(4) Subject to adjustment based on (i) final working capital adjustment calculations, and (ii) indemnification obligations of the acquired company stockholders.

Our consolidated financial statements include the operating results of all acquired businesses from the date of each acquisition. Pro forma results of operations for all 2013 acquisitions have not been presented in our consolidated financial statements as the financial impact to our consolidated financial statements both individually and in aggregate, are not material. There were no acquisitions completed during the nine months ended September 30, 2012.

NOTE 9: COMMITMENTS AND CONTINGENCIES

Office Lease Commitments

On June 20, 2013, TripAdvisor LLC (“TA LLC”), our indirect, wholly owned subsidiary, entered into a lease (the “Lease”), with Normandy Gap-V Needham Building 3, LLC, as landlord (the “Landlord”). 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.

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, and $123.9 million for 2018 and thereafter. The Lease has escalating rental payments and initial periods of free rent and therefore the effects of variable rent payments will be expensed on a straight-line basis over the life of the Lease in accordance with GAAP. All real estate taxes and other building operating costs paid during the term of the Lease will be expensed as incurred. TA LLC is 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. 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. TA LLC also has an option to extend the term of the Lease for two consecutive terms of five years each.

In connection with the Lease, on June 20, 2013, 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.

The following table presents our estimated future minimum rental payments under all operating leases with non-cancelable lease terms having initial terms in excess of one year as of September 30, 2013 (in thousands):

	Total Payments
2013 (remaining three months)	$	2,679
2014		10,221
2015		8,879
2016		12,951
2017		13,358
2018 and thereafter		149,643
Total (1)	$	197,731

(1) Excludes spending on anticipated leasehold improvements on our Needham, Massachusetts lease, including design, development, construction costs, the purchase and installation of equipment, and receipt of related Landlord incentives which we estimate will begin in October 2014.

There have been no other material changes outside the normal course of business to our contractual obligations and commercial commitments since December 31, 2012. (Refer to “Note 12—Commitments and Contingencies,” in the Notes to our Consolidated Financial Statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2012.)

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 U.S. Securities and Exchange Commission 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 claims for damages 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.

NOTE 10: INCOME TAXES

Each interim period is considered an integral part of the annual period and, accordingly, we measure our tax expense using an estimated annual effective tax rate. An enterprise is required, at the end of each interim reporting period, to make its best estimate of the annual effective tax rate for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, as adjusted for discrete taxable events that occur during the interim period.

Our effective tax rate for the three and nine months ended September 30, 2013 was 33.2% and 28.2%, respectively. Our effective tax rate for the three and nine months ended September 30, 2012 was 34.4% and 32.6%, respectively. For the three and nine months ended September 30, 2013, the effective tax rate is less than the federal statutory rate primarily due to earnings in jurisdictions outside the United States, where our effective tax rate is lower, which was partially offset by state income taxes, non-deductible stock compensation and accruals on uncertain tax positions. The decrease in the effective tax rate for 2013 compared to the 2012 rate was primarily due to an increase in earnings in jurisdictions outside the United States as well as an internal restructuring that occurred during the fourth quarter of 2012. This restructuring was undertaken within our non-US operations to align our global structure for more efficient treasury management and global cash deployment. Additionally, the rate for the three months ended September 30, 2013 includes a release of an accrual for uncertain tax benefits in the amount of $1.8 million as a result of receiving a Private Letter Ruling from a taxing authority.

Our policy is to recognize accrued interest and penalties related to unrecognized tax benefits and income tax liabilities as part of our income tax expense. As of September 30, 2013, accrued interest is $0.9 million, net of federal benefit, and no penalties have been accrued.

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 will file as part of a unitary combined group with Expedia for certain state tax returns for the 2012 tax period.

As of September 30, 2013, the Company’s tax years for 2009 through 2012 are subject to examination by the tax authorities in the United States, various states, and foreign jurisdictions. By virtue of previously filed consolidated income tax returns filed with Expedia, we are routinely under audit. We are currently under an IRS audit for the 2009 and 2010 tax years, and have various ongoing state income tax audits. As of September 30, 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.

NOTE 11: STOCKHOLDERS’ EQUITY

Common Stock and Class B Common Stock

Our authorized common stock consists of 1.6 billion shares of common stock with par value of $0.001 per share, and 400 million shares of Class B common stock with par value of $0.001 per share. Both classes of common stock qualify for and share equally in dividends, if declared by our Board of Directors. Common stock is entitled to one vote per share and Class B common stock is entitled to 10 votes per share on most matters. Holders of TripAdvisor common stock, acting as a single class, are entitled to elect a number of directors equal to 25% percent of the total number of directors, rounded up to the next whole number, which was three directors as of September 30, 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 131,372,883 and 129,289,174 shares of common stock issued and outstanding, respectively, at September 30, 2013 and 12,799,999 shares of Class B common stock issued and outstanding at September 30, 2013.

Preferred Stock

In addition to common stock, we are authorized to issue up to 100 million preferred shares, with $ 0.001 par value per share, with terms determined by our Board of Directors, without further action by our stockholders. At September 30, 2013, no preferred shares had been issued.

Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss is primarily comprised of accumulated foreign currency translation adjustments, as follows (in thousands):

	September 30, 2013			December 31, 2012
Net unrealized loss on securities, net of tax (1)	$	(151	)	$	(104	)
Cumulative foreign currency translation adjustments (2)		(1,157	)		(765	)
Total accumulated other comprehensive loss	$	(1,308	)	$	(869	)

(1) Net of unrealized tax benefits of $0.1 million and $0.1 million at September 30, 2013 and December 31, 2012, respectively.

(2) Our foreign subsidiary earnings are considered indefinitely reinvested; therefore; deferred taxes are not provided on foreign currency translation adjustments.

Treasury Stock

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. The repurchase program has no expiration date but may be suspended or terminated by the Board of Directors at any time. Our Board of Directors will determine the price, timing, amount and method of such repurchases based on its evaluation of market conditions and other factors, and any shares repurchased will be in compliance with applicable legal requirements, at prices determined to be attractive and in the best interests of both the Company and its stockholders.

During the nine month period ended September 30, 2013, we repurchased 2,083,709 shares of outstanding common stock under the share repurchase program at an aggregate cost of $142.3 million, of which $4.8 million remains payable at September 30, 2013. As of September 30, 2013, from the authorized share repurchase program granted by the Board of Directors we have remaining $107.7 million to repurchase shares of our common stock.

Dividends

During the period January 1, 2013 through September 30, 2013, our Board of Directors did not declare any dividends on our outstanding common stock and do not expect to pay any cash dividends for the foreseeable future.

NOTE 12: SEGMENT INFORMATION

We have one reportable segment: TripAdvisor. We determined our segment based on how our chief operating decision maker manages our business, makes operating decisions and evaluates operating performance. 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 Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” below.

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 (in thousands):

	Three months ended September 30,						Nine months ended September 30,
	2013			2012			2013			2012
Adjusted EBITDA	$	104,422		$	107,059		$	326,601		$	288,169
Depreciation (1)		(7,634	)		(5,037	)		(20,834	)		(14,033	)
Amortization of intangible assets		(1,443	)		(1,310	)		(4,182	)		(4,909	)
Stock-based compensation		(11,651	)		(8,463	)		(35,470	)		(19,923	)
Other expense, net		(71	)		(1,439	)		(8,154	)		(10,619	)
Provision for income taxes		(27,741	)		(31,275	)		(72,792	)		(77,814	)
Net income	$	55,882		$	59,535		$	185,169		$	160,871

(1) Includes amortization of internal use software and website development costs.

NOTE 13: EARNINGS PER SHARE

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. For the three and nine months ended September 30, 2013 and 2012, we computed the weighted average number of common shares outstanding during the period using the total of common stock and Class B common stock outstanding as of December 31, 2012 and 2011, respectively, plus the weighted average of any additional shares issued and outstanding less the weighted average of any treasury shares repurchased, during the three and nine months ended September 30, 2013 and 2012, respectively.

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. For the three and nine months ended September 30, 2013 and 2012, 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, (ii) if dilutive, the incremental weighted average common stock that we would issue upon the assumed exercise of common equivalent shares related to stock options and stock warrants and the vesting of restricted stock units using the treasury stock method during the three and nine months ended September 30, 2013 and 2012, respectively, 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.

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):

	Three months ended September 30,				Nine months ended September 30,
	2013		2012		2013		2012
Numerator:

Denominator:
Weighted average shares used to compute Basic EPS		142,690		142,342		143,095		138,458

Diluted EPS	$	0.38	$	0.41	$	1.27	$	1.14

22

The following potential common shares related to stock options 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 (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2013(1)		2012(2)		2013(1)		2012(2)
Stock options		1,360		4,921		2,559		3,584
RSUs		47		—		32		20
Total		1,407		4,921		2,591		3,604

(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 as of September 30, 2013; 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 and RSUs representing the right to acquire 110,000 shares and 400,000 shares of common stock for which all targets required to trigger vesting had not been achieved as of September 30, 2012; 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.

NOTE 14: RELATED PARTY TRANSACTIONS

Expedia

Subsequent to the Spin-Off, we remained a related party with Expedia due to common ownership of our shares and shares of Expedia by Liberty Interactive Corporation.

Related-party revenue from Expedia was $56.2 million and $171.0 million for the three and nine months ended September 30, 2013, respectively, and was $56.9 million and $164.2 million for the three and nine months ended September 30, 2012, 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. Related-party revenue represented 22.0% and 23.4% of our total revenue for the three and nine months ended September 30, 2013, respectively, and 26.7% and 27.7% of our total revenue for the three and nine months ended September 30, 2012, respectively. Other related-party operating expenses which were included within selling and marketing expense were $1.8 million and $4.9 million for the three and nine months ended September 30, 2013, respectively, and were $1.7 million and $5.2 million for the three and nine months ended September 30, 2012, respectively, which primarily consisted of marketing expense for exit windows. The net related party receivable balances with Expedia reflected in our consolidated balance sheets as of September 30, 2013 and December 31, 2012 were $33.9 million and $24.0 million, respectively.

Liberty Interactive Corporation

As of September 30, 2013, Liberty Interactive Corporation, or 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 as of September 30, 2013.

We had no related party transactions with Liberty during the nine months ended September 30, 2013 and 2012, respectively.

Overview

We are the world’s largest online travel company, empowering users to plan and have the perfect trip. Our travel research platform aggregates reviews and opinions from our community about destinations, accommodations (including hotels, resorts, motels, B&Bs, specialty lodging and vacation rentals), restaurants and activities throughout the world through our flagship TripAdvisor brand. Our branded websites include tripadvisor.com in the United States and localized versions of the website in 33 other countries, including China under the brand daodao.com. Our TripAdvisor branded websites globally averaged more than 260 million monthly unique visitors for the quarter ended September 30, 2013, according to Google Analytics. We feature over 125 million reviews and opinions and we have built a base of approximately 57 million marketable members. Marketable members are members that have registered on our site and given us permission to email them. While we believe growth in marketable members increases user engagement and traffic to our site, we do not consider it to be a key driver of our overall revenue. Beyond travel-related content, our websites also include links to the websites of our customers, including travel advertisers, allowing travelers to directly book their travel arrangements. In addition to the flagship TripAdvisor brand, we now manage and operate 20 other travel media brands: www.airfarewatchdog.com, www.bookingbuddy.com, www.cruisecritic.com, www.everytrail.com, www.familyvacationcritic.com, www.flipkey.com, www.gateguru.com, www.holidaylettings.co.uk, www.holidaywatchdog.com, www.independenttraveler.com, www.jetsetter.com, www.niumba.com, www.onetime.com, www.seatguru.com, www.smartertravel.com, www.tingo.com, www.travelpod.com, www.virtualtourist.com, www.whereivebeen.com, and www.kuxun.cn, connected by the common goal of providing comprehensive travel planning resources across the travel sector.

Business Model

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. The remainder of our revenue is generated through a combination of subscription-based offerings, selling room nights on our transactional sites, and other revenue including content licensing. For the nine months ended September 30, 2013, we earned $552 million in revenue from click-based advertising, $86 million in revenue from display-based advertising and $94 million in revenue from subscription-based offerings, transaction revenue and other revenue.

• Click-Based Advertising Revenue. Our largest source of revenue is click-based advertising, which includes links to our partners’ booking sites and contextually-relevant branded and unbranded textlinks. Our click-based advertising partners are predominantly online travel agencies and direct suppliers in the hotel, airline and cruise product categories. Click-based advertising is generally priced on a cost-per-click, or CPC, basis, with payments from advertisers based on the number of users who click on each type of link. Most of our click-based advertising contracts can be terminated by the advertisers at will or on short notice.

• Display-Based Advertising Revenue. We earn revenue from a variety of display-based advertising placements on our websites through which our advertising partners can promote their brands in a contextually-relevant manner. While our display-based advertising clients are predominately direct suppliers in the hotel, airline and cruise categories and online travel agencies, we also accept display advertising from marketing organizations, casinos, resorts and attractions, as well as advertisers from non-travel categories. We generally sell our display-based advertising on a cost per thousand impressions, or CPM, basis. Our display-based advertising products also include a number of custom-built products including the sponsorship of certain site features and functionality, as well as certain customized co-branded features.

• Subscription-Based, Transaction and Other Revenue. We offer advertising via a subscription model that is sold for a flat fee per time period. Managed by our TripAdvisor for Business division, this advertising product, Business Listings, is currently offered to hotels, B&Bs and other specialty lodging properties and allows subscribers to list a website URL, email address and phone number on TripAdvisor-branded websites as well as to post special offers for travelers. Our Vacation Rentals product allows individual vacation property owners and property managers to pay a subscription fee or to use a new free-to-list option to list properties on our U.K.-based Holiday Lettings, U.S.-based FlipKey and our recently-acquired Spain-based Niumba websites, as well as on select TripAdvisor-branded websites. Other sources of revenue include selling room nights on our transactional sites, including our recently-acquired Jetsetter business and Tingo, as well as content licensing arrangements with third-party sites.

Executive Summary

Our financial results are currently principally dependent on our ability to drive our click-based advertising revenue. We continue to invest in areas of potential click-based revenue growth, including our social, mobile and global initiatives, while also focusing on growing both our subscription-based products, such as Vacation Rentals and Business Listings, and our transaction-based businesses. We have leveraged our position as the largest online travel company to become an important partner for online advertisers—including hotels, online travel agencies and other travel-related service providers—by providing our customers with access to our large audience of highly-qualified, highly-engaged users. The key drivers of our click-based and display-based advertising revenue are described below, as well as a summary of our key growth areas and the current trends impacting our business.

Key Drivers of Click-Based Advertising Revenue

For the three and nine months ended September 30, 2013, 74% and 75%, respectively, of our total revenue came from our core CPC-based lead generation product. For the three and nine months ended September 30, 2012, 79% and 78%, respectively, of our total revenue came from our CPC-based lead generation product. The key drivers of our click-based advertising revenue include the growth in monthly unique hotel shoppers and revenue per hotel shopper.

• Hotel shoppers: Total traffic growth, or growth in monthly visits from unique visitors, is reflective of our overall brand growth. We track and analyze sub-segments of traffic and their correlation to revenue generation and utilize hotel shoppers as an indicator of revenue growth. We use the term “hotel shoppers” to refer to users who view a listing of hotels in a city or visitors who view a specific hotel page. Hotel shoppers tend to be seasonal and also tend to vary based on general economic conditions. Our number of hotel shoppers increased 37% and 40% for the three and nine month periods ended September 30, 2013, respectively, and increased 29% and 31% for the three and nine months ended September 30, 2012, respectively, according to our log files.

• Revenue per hotel shopper: Revenue per hotel shopper is a metric we use to analyze how effectively we are able to monetize hotel shoppers based on a combination of user conversion and pricing. User conversion is a measure of how many hotel shoppers ultimately click on a CPC link that generates revenue for us. User conversion on our site is primarily driven by three factors: merchandising, commerce coverage and choice. We define merchandising as the number and location of ads that are available on a page; we define commerce coverage as whether we have a client who can take an online booking for a particular property; and we define choice as the number of clients available for any given property, allowing the user to shop for the best price. Pricing is the effective CPC that online travel agencies and hoteliers are willing to pay us for a hotel shopper lead. Revenue per hotel shopper decreased 19% and 15% for the three and nine months ended September 30, 2013, respectively, and decreased 9% for both the three and nine month periods ended September 30, 2012.

25

In summary, our CPC revenue depends on the number of hotel shoppers that are interested in a property, whether there is a commerce link available for that hotel shopper to click on for that property, whether there are several commerce choices available for that property so the hotel shopper can shop around and what our customers are willing to pay us for the lead.

Key Drivers of Display-Based Advertising Revenue

For both the three and nine months ended September 30, 2013, 12% of our total revenue came from our display-based advertising product. The key drivers of our display-based advertising revenue include the growth in number of impressions, or the number of times an ad is displayed on our site, and the cost per thousand impressions, or CPM (or pricing). Our number of impressions increased 36% and 27% for the three and nine months ended September 30, 2013, respectively, and decreased 2% and increased 7% for the three and nine months ended September 30, 2012, respectively, while pricing decreased 4% and 6% for the three and nine months ended September 30, 2013, respectively, and increased 9% and 3% for the three and nine months ended September 30, 2012, respectively.

Key Growth Areas

We continue to invest in areas of potential growth, including our social, mobile and global initiatives as well as our subscription-based products, such as Vacation Rentals and Business Listings.

Social. Our Wisdom of Friends initiative is a core component of our strategic growth plan; 76% of respondents to a recent Nielsen study cited “recommendations from people I know” as the information source that they trust most. We believe that having a strong social presence improves engagement on our sites and improves the sites’ “stickiness” amongst the users. As a result, we continue to deepen our integration with Facebook. As of September 30, 2013, and according to AppData, an independent application tracking traffic service, TripAdvisor has averaged more than 39 million monthly Facebook users via its TripAdvisor Facebook application id. We offer these Facebook users a more personalized and social travel planning experience that enables travelers to engage with their own Facebook friends’ reviews and opinions when planning their perfect trip on TripAdvisor.

Mobile. Mobile is an investment area that is geared towards creating a more complete user experience by reinforcing the TripAdvisor brand when users are in-market. In the quarter ended September 30, 2013, we saw strong mobile user uptake, as aggregate downloads of our TripAdvisor, City Guides, SeatGuru, Jetsetter and GateGuru mobile apps reached 69 million downloads and average unique monthly visitors via smartphone and tablet devices grew 177% year-over-year from 39.2 million to 108.4 million, according to company logs. We believe that travelers will increasingly use mobile devices, including smartphones and tablets, to conduct travel research and planning.

Vacation Rentals. Our Vacation Rentals product addresses a highly-fragmented $85 billion per-year vacation rental industry, according to a 2010 Radius Global Market study. As of December 31, 2012, we had amassed over 300,000 properties, up more than 50% during the year, across our TripAdvisor Vacation Rentals, U.S.-based FlipKey, and U.K.-based Holiday Lettings, as well as through partnership agreements with other vacation rental businesses. We offer individual property owners and property managers the ability to list using a subscription-based fee structure or a free-to-list, commission-based option and we believe our highly-engaged and motivated user community creates a competitive advantage for us in this market.

Business Listings. Our Business Listings product enables hotel and accommodation owners to list pertinent property information on TripAdvisor, bringing them closer to potential customers and thereby increasing direct bookings. In the year ended December 31, 2012, we grew our Business Listings customer base over 40% to 50,000 subscribers, representing just over 7% of our current hotel and accommodation listings on TripAdvisor branded sites. We continue to expand our sales force and introduce new product features and functionality to grow our subscriber base.

Current Trends Affecting Our Business

Increasing Competition. The travel review industry and, more generally, the business of collecting and aggregating travel-related resources and information, continues to be increasingly competitive. In recent years, an increasing number of companies, such as search companies Google Inc. and Baidu.com, Inc. and several large online travel agencies, have begun to collect and aggregate travel information and resources. We plan to continue to invest in order to remain the leading source of travel reviews as well as continue to enhance our content and user experience.

26

Increasing Use of Internet and Social Media to Access Travel Information. Commerce, information and advertising continue to migrate to the Internet and away from traditional media outlets. We believe that this trend will create strategic growth opportunities, allowing us to attract new consumers and develop unique and effective advertising solutions. Consumers are increasingly using online social media, such as Facebook, as a means to communicate and exchange information, including travel information and opinions. We have made significant efforts related to social networking in order to leverage the expanding use of this channel and enhance traffic diversification and user engagement. We are also continually adapting our user experience in response to a changing Internet environment and usage trends. For example, in 2012 we invested in building and introducing to users hotel metasearch functionality for our smartphone platforms and in early June 2013 completed the process of implementing hotel metasearch functionality on our desktop and tablet platforms. Refer to our metasearch discussion below in “Our Strategy” in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section for additional information on our hotel metasearch transition.

Increasing Mobile Usage. Users are increasingly using smartphone and tablet computing devices to access the Internet. To address these growing user demands, we continue to extend our platform to develop smartphone and tablet applications to deliver travel information and resources. Although the substantial majority of our smartphone users also access and engage with our websites on personal computers and tablets where we display advertising, our users could decide to access our products primarily through smartphone devices. We have just begun to display graphic advertising on smartphones, however, our smartphone monetization strategies are still developing, as smartphone monetization was less than 20% of desktop monetization of hotel shoppers during the nine months ended September 30, 2013 while tablets monetize more closely to desktops. Mobile growth and development remains a key company priority and we will continue to invest and innovate in this growing platform to help us maintain and grow our user base and engagement over the long term.

Click-Based Advertising Revenue. In recent years, the majority of our revenue growth resulted from higher click-based advertising revenue due to increased traffic on our websites and an increase in the volume of clicks on our advertisers’ placements. Although click-based advertising revenue growth has generally been driven by traffic volume, we remain focused on the various factors that could impact revenue growth, including, but not limited to, the growth in hotel shoppers, CPC pricing fluctuations, the overall economy, the ability of advertisers to monetize our traffic, the quality and mix of traffic to our websites, and the quality and mix of traffic from our advertising placements to advertisers, as well as advertisers’ evolving approach to transaction attribution models and return on investment targets. We monitor and regularly respond to changes in these factors in order to strategically improve our user experience, customer satisfaction and monetization in this dynamic environment. For example, in order to improve user experience, we introduced metasearch functionality to our hotel shoppers as discussed below in “—Our Strategy.”

Global Economic Conditions. In late 2008 and throughout 2009, weak global economic conditions created uncertainty for travelers and suppliers, and put pressure on discretionary spending on travel and advertising. Since 2010, the travel industry has been gradually improving. However, global economic conditions remain uncertain, and in particular, we anticipate travel expenditures in Europe to continue to be adversely effected by the economic issues overseas.

27

Our Strategy

In expanding our global reach, we leverage significant investments in technology, operations, brand-building, and advertiser and other partner relationships. For example, we are able to aggregate a large base of consumer reviews, in a variety of languages, across our global core platform. We expect to continue leveraging this investment when launching additional points of sale in new countries, introducing new product features and adding new business model offerings.

• Investment in Technology. We believe that our ability to continue to innovate by providing additional functionality to our main Internet sites, while at the same time continuing to extend that functionality to additional platforms such as smartphones and tablets, will enable us to continue providing an industry-leading user experience. We have a strong culture of speed-to-market with our innovations. By innovating and releasing updates quickly, we believe that we can continue to grow our site visitors and over 125 million reviews and opinions, increase revenue and effectively compete with our competitors.

• Social Platform. We intend to continue to expand our social integration and member acquisition efforts with social media, including Facebook, Twitter and other social sharing platforms. We believe that this integration will enable us to continue to grow and maintain engagement with our user base and increase our content. For example, when searching for a hotel on TripAdvisor, users can see which hotels their Facebook friends and friends-of-friends have visited and reviewed. Users can share their reviews and ratings with their friends and publish their activity to their timelines. Users can also update their travel map and rate new experiences on Facebook.

• Metasearch. A metasearch display is an interface that shows hotel or flight availability and pricing information from multiple sources, without requiring the user to visit another website. We have offered a flight metasearch product since 2009, expanding internationally to 19 points of sale in 2012 and increasing to 29 points of sale as of September 30, 2013. In 2012, we invested in building hotel metasearch functionality for our smartphone platforms and introducing it to 100% of our global smartphone traffic. In early June 2013, we completed the process of fully implementing hotel metasearch functionality onto our desktop and tablet platforms. We believe metasearch functionality provides a better user experience while delivering more valuable leads to advertising partners, however at a lower volume per session. Click-based advertising customers are receiving higher converting leads and therefore are paying higher per-unit prices, which we expect will offset the decreased lead volume. We expect to continue to invest in evolving our metasearch functionality on our site, because we believe that providing hotel and flight pricing and availability deliver a better user experience.

• Investment in Search Engine Marketing. One of the ways that we look to penetrate new markets is to leverage our expertise in search engine marketing, or SEM. SEM is a form of Internet marketing that involves the promotion of websites by increasing their visibility in search engine results pages through the use of paid placement, contextual advertising, and paid inclusion. In certain markets we may bid on keywords to break even or at a loss in order to drive traffic, build our brand, gain more users to our product, collect content and scale more quickly. We think SEM is an important channel because it delivers a significant number of brand impressions and can be a cost-effective method to get people to try our sites.

• Enhance International Offerings. We are focused on strengthening our broad global footprint. We are continuing to improve localization and grow our user base in Europe, Asia and South America, especially in emerging markets, such as Brazil, Russia and China. These and the other newer sites in Asia-Pacific represent a longer-term opportunity for us. We believe that China represents a large international opportunity for our business. We currently have two lead product offerings in the Chinese market—DaoDao and Kuxun—both headquartered in Beijing. We continue to invest heavily and operate at a loss in the Chinese market.

• Acquisitions. We have a history of successfully acquiring and integrating companies that expand our footprint either geographically or in market sectors that are complementary to our flagship properties. We intend to continue to seek acquisition targets.

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.

Employees

As of September 30, 2013, we had 1,939 employees. Of these employees, 1,118 were based in the United States. None of our employees are represented by a labor union or are subject to a collective bargaining agreement. We believe that relations with our employees are good.

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 historically 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.

28

Critical Accounting Policies and Estimates

Critical accounting policies and estimates are those that we believe are important in the preparation of our consolidated financial statements because they require that management use judgment and estimates in applying those policies. We prepare our consolidated financial statements and accompanying notes in accordance with GAAP. Preparation of the consolidated financial statements and accompanying notes requires that management make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements as well as revenue and expenses during the periods reported. Management bases its estimates on historical experience, where applicable and other assumptions that it believes are reasonable under the circumstances. Actual results may differ from estimates under different assumptions or conditions.

There are certain critical estimates that we believe require significant judgment in the preparation of our consolidated financial statements. We consider an accounting estimate to be critical if:

• It requires us to make an assumption because information was not available at the time or it included matters that were highly uncertain at the time we were making the estimate; and

• Changes in the estimate or different estimates that we could have selected may have had a material impact on our financial condition or results of operations.

There have been no material changes to our critical accounting policies and estimates as compared to the critical accounting policies and estimates described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012. Refer to “Note 2—Significant Accounting Policies,” for additions to our critical accounting policies for the nine months ended September 30, 2013.

New Accounting Pronouncements

For a discussion of new accounting pronouncements, see “Note 2—Significant Accounting Policies,” in the notes to the consolidated financial statements in this Quarterly Report on Form 10-Q. We are an “issuer” (as defined in Section 2(a) of the Sarbanes-Oxley Act of 2002), and, as such, are required to comply with all new and revised accounting standards applicable to public companies.

Adjusted EBITDA

To provide investors with additional information regarding our financial results, we have disclosed Adjusted EBITDA in this Quarterly Report on Form 10-Q, a non-GAAP financial measure. We have provided reconciliations below of Adjusted EBITDA to net income, the most directly comparable GAAP financial measure. A “non-GAAP financial measure” refers to a numerical measure of a company’s historical or future financial performance, financial position, or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP in such company’s financial statements.

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. Adjusted EBITDA is the primary metric by which management evaluates the performance of its business and on which internal budgets are based. In particular, the exclusion of certain expenses in calculating Adjusted EBITDA facilitates operating performance comparisons on a period-to-period basis. Adjusted EBITDA eliminates items that are either not part of our core operations, such as non-recurring expenses, or those costs that do not require a cash outlay, such as stock-based compensation. Adjusted EBITDA also excludes depreciation and amortization expense, which is based on our estimates of the useful life of tangible and intangible assets. These estimates could vary from actual performance of the asset, are based on historical costs and other factors and may not be indicative of current or future capital expenditures. We believe that by excluding certain items, such as stock-based compensation and non-recurring expenses, Adjusted EBITDA corresponds more closely to the cash that operating income generated from our business and allows investors to gain an understanding of the factors and trends affecting the ongoing cash earnings capabilities of our business, from which capital investments are made and debt is serviced.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results reported in accordance with GAAP. Some of these limitations are:

• Adjusted EBITDA does not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments;

• Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

• Adjusted EBITDA does not consider the potentially dilutive impact of stock-based compensation;

• Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements;

• Adjusted EBITDA does not reflect tax payments that may represent a reduction in cash available to us; and

• Other companies, including companies in our own industry, may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, including various cash flow metrics, net income and our other GAAP results.

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 (in thousands):

Revenue

We derive substantially all of our revenue through the sale of advertising, primarily through click-based advertising and, to a lesser extent, display-based advertising. In addition, we earn revenue through a combination of subscription-based offerings related to our Business Listings and Vacation Rentals products, transaction revenue from selling room nights on our transactional sites, and other revenue including content licensing.

Total revenue	$	255	$	213		20	%	$	732	$	594		23	%

Revenue increased $42 million and $138 million during the three and nine months ended September 30, 2013, respectively, when compared to the same periods in 2012, primarily due to an increase in click-based advertising revenue of $21 million and $88 million, respectively. The primary driver of the increase in click-based advertising revenue was an increase in hotel shoppers of 37% and 40% for the three and nine months September 30, 2013, respectively, partially offset by lower revenue per hotel shopper of 19% and 15% for the three and nine months ended September 30, 2013, respectively, primarily due to a combination of lower user conversion related to our transition to hotel metasearch, growth in hotel shoppers on smartphones, which have a lower monetization rate than desktops and tablets, and growth in emerging international markets that are currently monetizing at lower levels than our mature markets. We expect the lower user conversion trend to continue due to our recent transition to hotel metasearch, which we anticipate will negatively impact revenue growth over the balance of the year. Display-based advertising increased by $7 million and $14 million during the three and nine months ended September 30, 2013, respectively, primarily as a result of a 36% and 27% increase in the number of impressions during the three and nine months ended September 30, 2013, respectively, when compared to the same periods in 2012, partially offset by a decrease in pricing by 4% and 6% for the three and nine months ended September 30, 2013, respectively. Subscription, transaction and other revenue increased by $14 million and $36 million during the three and nine month periods ended September 30, 2013, respectively, primarily due to growth in Business Listings.

The following table presents our revenue by geographic region, which reflects how we measure our business internally. Revenue by geography is based on the location of our websites:

International revenue increased $27 million and $79 million during the three and nine months ended September 30, 2013, respectively, compared to the same periods in 2012. International revenue represented 53% and 51% of total revenue during the three and nine months ended September 30, 2013, and represented 50% and 49% of total revenue during the three and nine months ended September 30, 2012, respectively. The increase in international revenue, in absolute dollars and as a percentage of total revenue, is primarily due to additional investment in international expansion and growth in international hotel shoppers.

In addition to the product and geographic revenue discussion above, related-party revenue from Expedia, which consists primarily of click-based advertising, is as follows:

Related-party revenue from Expedia increased $7 million during the nine months ended September 30, 2013 when compared to the same period in 2012, primarily due to lower click volume sent to Expedia, primarily related to our transition to hotel metasearch which was more than offset by higher CPC pricing paid by Expedia during this time period. For information on our relationship with Expedia, including recent material transactions, refer to “Note 14—Related Party Transactions” in the notes to our consolidated financial statements.

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.

Cost of revenue increased $2 million and $4 million during the three and nine month periods ended September 30, 2013, respectively, when compared to the same periods in 2012, primarily due to increased data center costs, driven by higher site traffic and merchant credit card fees.

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.

33

Direct selling and marketing costs increased $21 million and $36 million during the three and nine month periods ended September 30, 2013, respectively, when compared to the same periods in 2012, primarily due to increased SEM costs, other traffic acquisition costs, and brand advertising costs, partially offset by a decrease in spending in social media costs. Personnel and overhead costs increased $9 million and $25 million during the three and nine month periods ended September 30, 2013, respectively, when compared to the same periods in 2012, primarily due to an increase in headcount to support business growth, including international expansion, and employees joining us through recent business acquisitions.

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 and maintenance of our websites. Other costs include licensing and maintenance expense.

Technology and content costs increased $10 million and $32 million during the three and nine months ended September 30, 2013, respectively, when compared to the same periods in 2012, primarily due to increased personnel costs from increased headcount to support business growth, including international expansion, enhanced site features, extending our products onto smartphone and tablet platforms, and development of our new hotel metasearch product, as well as an increase in stock based compensation and additional personnel costs related to employees joining us through recent business acquisitions.

General and Administrative

General and administrative expense consists 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.

General and administrative costs increased $5 million and $18 million during the three and nine months ended September 30, 2013, respectively, when compared to the same periods in 2012, primarily due to increased personnel costs related to an increase in stock-based compensation, as well as increased headcount to support business growth and additional professional service fees in order to support our operations as a standalone public company and an increase in our bad debt provision.

The change in intangible asset amortization is not material for the periods presented. Refer to “Note 7—Goodwill and Intangible Assets, Net” for estimated remaining intangible amortization for the year ending December 31, 2013.

Interest Income

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

The increase in interest income is primarily due to the fact that we began investing in marketable securities during the fourth quarter of 2012. Refer to “Note 4—Financial Instruments” for additional information on our current portfolio as of September 30, 2013.

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.

The decrease in interest expense is primarily due to the slightly lower outstanding borrowings and interest rates for the three and nine month periods ended September 30, 2013 over the same periods during 2012. Refer to “Note 5—Debt” for additional information on our outstanding borrowings at September 30, 2013.

Effective tax rate		33.2	%		34.4	%					28.2	%		32.6	%

For the three and nine months ended September 30, 2013, our effective tax rate is less than the federal statutory tax rate primarily due to earnings in jurisdictions outside the United States, where our effective tax rate is lower, which was partially offset by state income taxes, non-deductible stock compensation and accruals on uncertain tax positions. The change in the effective tax rate for 2013 compared to the 2012 rate was primarily due to an increase in earnings in jurisdictions outside the United States as well as the internal restructuring that was implemented in the last quarter of 2012. Additionally, the rate for the quarter includes a release of an accrual for uncertain tax benefits in the amount of $1.8 million as a result of receiving a Private Letter Ruling from a taxing authority.

Related Party Transactions

For information on our relationships with Expedia and Liberty Interactive Corporation, including recent material transactions, refer to “Note 14—Related Party Transactions” in the notes to our consolidated financial statements.

Stock-Based Compensation

Refer to “Note 3—Stock Based Awards and Other Equity Instruments” for further information on current year equity award activity, including the issuance of 2,776,247 primarily service based stock options with a weighted average grant-date fair value per option of $28.11 and 1,083,082 RSUs with a weighted average grant-date fair value of $48.84 during the nine months ended September 30, 2013.

Financial Position, Liquidity and Capital Resources

Our principal sources of liquidity are cash flows generated from operations. At September 30, 2013 and December 31, 2012, we had $596 million, which does not include $40.4 million of cash related to unsettled sales of marketable securities which was received subsequent to report date, and $586 million, respectively, of cash, cash equivalents and short and long-term available-for-sale marketable securities. As of September 30, 2013, approximately $374 million of our cash, cash equivalents, and short and long-term marketable securities were held by our international subsidiaries, primarily in the United Kingdom, and are related to earnings we intend to reinvest permanently outside the United States. Should we distribute earnings of foreign subsidiaries in the form of dividends or otherwise, we may be subject to U.S. income taxes. Cumulative undistributed earnings of foreign subsidiaries that we intend to indefinitely reinvest outside of the United States totaled approximately $466 million as of September 30, 2013. Should we distribute, or be treated under certain U.S. tax rules as having distributed, the earnings of foreign subsidiaries in the form of dividends or otherwise, we may be subject to U.S. income taxes. Determination of the amount of any unrecognized deferred income tax liability on this temporary difference is not practicable because of the complexities of the hypothetical calculation. Cash held is primarily denominated in U.S. dollars.

Historically, the cash we generate has been sufficient to fund our working capital requirements, capital expenditures and to meet our long-term debt obligations and commitments. Management believes that our cash and cash equivalents and available-for-sale marketable securities, combined with expected cash flows generated by operating activities and available cash from our credit facilities will be sufficient to fund our ongoing working capital requirements, capital expenditures, business growth initiatives, meet our long term debt obligations and commitments, share repurchases and fund any potential acquisitions for at least the next twelve months. However, if during that period or thereafter, we are not successful in generating sufficient cash flow from operations or in raising additional capital when required in sufficient amounts and on terms acceptable to us, we may be required to reduce our planned capital expenditures and scale back the scope of our business growth initiatives, either of which could have a material adverse effect on our future financial condition or results of operations.

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 September 30, 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. A 25 basis point change in the interest rate on the current Term Loan balance would result in an increase or decrease to interest expense of approximately $0.9 million per annum.

36

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 $30 million were made during the nine months ended September 30, 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 September 30, 2013, there are no outstanding borrowings under our Revolving Credit Facility.

During the three and nine months ended September 30, 2013, we recorded total interest and commitment fees on our Credit Agreement of $1.8 million and $5.9 million, respectively, to interest expense on our consolidated statement of operations. During the three and nine months ended September 30, 2012, we recorded total interest and commitment fees on our Credit Agreement of $2.1 million and $6.5 million, respectively, to interest expense on our consolidated statements of operations. All unpaid interest and commitment fee amounts as of September 30, 2013 and December 31, 2012 were not material.

The remaining future minimum principal payment obligations due under the Credit Agreement related to our Term Loan is as follows as of September 30, 2013 (in millions):

	Payment Amount
2013 (remaining three months)	$	10
2014	$	40
2015	$	40
2016	$	260
Total	$	350

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 contain 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 September 30, 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 September 30, 2013 and December 31, 2012, we had short term borrowings outstanding of $26.2 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 nine months ended September 30, 2013, we made a payment inclusive of interest of RMB 68,283,570 (approximately $10.9 million). We currently have $11.9 million of outstanding borrowings from this credit facility as of September 30, 2013. Our Chinese Credit Facility—BOA currently bears interest based at 100% of the People’s Bank of China’s base rate and was 5.6% as of September 30, 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 nine months ended September 30, 2013, we made a payment inclusive of interest of RMB 24,281,546 (approximately $3.9 million). We currently have $14.3 million of outstanding borrowings from this credit facility as of September 30, 2013. Our Chinese Credit Facility—JPM currently bears interest based at 100% of the People’s Bank of China’s base rate and was 5.6% as of September 30, 2013.

Contractual Obligations, Commercial Commitments and Off-Balance Sheet Arrangements

Office Lease Commitments

On June 20, 2013, TripAdvisor LLC (“TA LLC”), our indirect, wholly owned subsidiary, entered into a lease (the “Lease”), with Normandy Gap-V Needham Building 3, LLC, as landlord (the “Landlord”). 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.

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, and $123.9 million for 2018 and thereafter. The Lease has escalating rental payments and initial periods of free rent and therefore the effects of variable rent payments will be expensed on a straight-line basis over the life of the Lease in accordance with GAAP. All real estate taxes and other building operating costs paid during the term of the Lease will be expensed as incurred. TA LLC is 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. 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. TA LLC also has an option to extend the term of the Lease for two consecutive terms of five years each.

In connection with the Lease, on June 20, 2013, 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.

The following table presents our estimated future minimum rental payments under all operating leases with non-cancelable lease terms having initial terms in excess of one year as of September 30, 2013 (in millions):

	Total Payments
2013 (remaining three months)	$	3
2014		10
2015		9
2016		13
2017		13
2018 and thereafter		150
Total (1)	$	198

(1) Excludes spending on anticipated leasehold improvements on our Needham, Massachusetts lease, including design, development, construction costs, and the purchase and installation of equipment, and the receipt of related Landlord incentives, which we estimate will begin in October 2014.

There have been no other material changes outside the normal course of business to our contractual obligations and commercial commitments since December 31, 2012. Refer to “Contractual Obligations, Commercial Commitments and Off-Balance Sheet Arrangements” in Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations of our Annual Report on Form 10-K for the year ended December 31, 2012.

Off-Balance Sheet Arrangements

As of September 30, 2013, we did not have any off-balance sheet arrangements 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.

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 claims for damages 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.

Consolidated Cash Flow Statements Discussion

Our cash flows are as follows (in millions):

	Nine months ended September 30,
	2013			2012
Net cash provided by (used in):
Operating activities	$	278		$	168
Investing activities	$	(216	)	$	(14	)
Financing activities	$	(154	)	$	213

Operating Activities

For the nine months ended September 30, 2013, net cash provided by operating activities increased by $110 million or 65% when compared to the same period in 2012, primarily due to an increase in net income of $24 million, an increase in non-cash items not affecting cash flows of $21 million, which is primarily related to increased stock based compensation and depreciation. Working capital movements increased $65 million for the period ending September 30, 2013 when compared to the same period in 2012, primarily due to an increase in 2013 related to positive operating cashflow from deferred merchant payables of $14 million with the remaining increase related to the timing of customer receipts, related party cash receipts, and tax and vendor payments.

Investing Activities

For the nine months ended September 30, 2013, net cash provided by investing activities decreased by $202 million when compared to the same period in 2012, primarily due to a net increase in marketable securities purchase activity of $146 million, cash paid for 2013 business acquisitions of $32 million, net of cash acquired, and an increase in capital expenditures of $19 million. In addition, we received $7 million during the three months ended March 31, 2012 from Expedia related to the Spin-Off, which did not reoccur in 2013.

Financing Activities

For the nine months ended September 30, 2013, net cash provided by financing activities decreased by $367 million when compared to the same period in 2012 primarily due to an increase of $15 million in principal payments on our term loan, payments of $138 million for common stock share repurchases under our authorized share repurchase program, a reduction of $205 million in proceeds related to the exercise of our stock options and warrants, as all remaining warrants were settled in the first nine months of 2012, and a $15 million repayment of our outstanding borrowings on our Chinese Credit Facilities in 2013. This was offset a $10 million repayment of our outstanding borrowing on our Revolving Credit Facility in 2012 that did not reoccur in 2013.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market Risk Management

We are exposed to certain market risks, including changes in interest rates and foreign currency exchange rates that could adversely affect our results of operations or financial condition. We manage our exposure to these risks through established policies and procedures and by assessing the anticipated near-term and long-term fluctuations in interest rates and foreign currency exchange rates. Our objective is to mitigate potential income statement, cash flow and market exposures from changes in interest and foreign exchange rates.

There has been no material change in our market risk profile during the nine months ended September 30, 2013. For additional information, see Item 7A, Quantitative and Qualitative Disclosures About Market Risk, in Part II of our Annual Report on Form 10-K for the year ended December 31, 2012.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of September 30, 2013, our management, with the participation of our President and Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(b) promulgated under the Securities Exchange Act of 1934, as amended, or the Exchange Act. Based upon that evaluation, our President and Chief Executive Officer and our Chief Financial Officer concluded that, as of September 30, 2013, our disclosure controls and procedures were effective in ensuring that material information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s, or the SEC’s, rules and forms, including ensuring that such material information is accumulated and communicated to our management, including our President and Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes to our internal control over financial reporting that occurred during the quarter ended September 30, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. 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 TripAdvisor and our 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.

Item 1A. Risk Factors

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in Part I—Item 1A., “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2012 which could materially affect our business, financial condition or future results. There have been no material changes in our risk factors from those disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Unregistered Sales of Equity Securities

During the quarter ended September 30, 2013, we did not issue or sell any shares of our common stock, Class B common stock or other equity securities pursuant to unregistered transactions in reliance upon an exemption from the registration requirements of the Securities Act of 1933, as amended.

Share Repurchases

In February 2013, we announced that our Board of Directors authorized the repurchase of $250 million of shares of our 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. The repurchase program has no expiration date but may be suspended or terminated by the Board of Directors at any time. Our Board of Directors will determine the price, timing, amount and method of such repurchases based on its evaluation of market conditions and other factors, and any shares repurchased will be in compliance with applicable legal requirements, at prices determined to be attractive and in the best interests of both the company and its stockholders.

Commitments and Contingencies

NOTE 9: COMMITMENTS AND CONTINGENCIES

Office Lease Commitments

On June 20, 2013, TripAdvisor LLC (“TA LLC”), our indirect, wholly owned subsidiary, entered into a lease (the “Lease”), with Normandy Gap-V Needham Building 3, LLC, as landlord (the “Landlord”). 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.

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, and $123.9 million for 2018 and thereafter. The Lease has escalating rental payments and initial periods of free rent and therefore the effects of variable rent payments will be expensed on a straight-line basis over the life of the Lease in accordance with GAAP. All real estate taxes and other building operating costs paid during the term of the Lease will be expensed as incurred. TA LLC is 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. 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. TA LLC also has an option to extend the term of the Lease for two consecutive terms of five years each.

In connection with the Lease, on June 20, 2013, 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.

The following table presents our estimated future minimum rental payments under all operating leases with non-cancelable lease terms having initial terms in excess of one year as of September 30, 2013 (in thousands):

	Total Payments
2013 (remaining three months)	$	2,679
2014		10,221
2015		8,879
2016		12,951
2017		13,358
2018 and thereafter		149,643
Total (1)	$	197,731

(1) Excludes spending on anticipated leasehold improvements on our Needham, Massachusetts lease, including design, development, construction costs, the purchase and installation of equipment, and receipt of related Landlord incentives which we estimate will begin in October 2014.

There have been no other material changes outside the normal course of business to our contractual obligations and commercial commitments since December 31, 2012. (Refer to “Note 12—Commitments and Contingencies,” in the Notes to our Consolidated Financial Statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2012.)

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 U.S. Securities and Exchange Commission 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 claims for damages 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.

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES

Deferred Merchant Payables

We receive cash from travelers at the time of booking related to our 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 September 30, 2013, our deferred merchant payables balance was $28.6 million and for the nine months ended September 30, 2013, the related transactions generated positive operating cash flow of $12.8 million. A payable balance of $14.5 million was acquired with our business acquisitions during the nine months ended September 30, 2013. For additional information on our business acquisitions refer to “Note 6—Acquisitions” below. The deferred merchant payables balance at December 31, 2012 was $1.3 million.

There have been no material changes or other additions to our significant accounting policies since December 31, 2012. For additional information about our critical accounting policies and estimates, refer to “Note 2—Significant Accounting Policies,” included in our Annual Report on Form 10-K for the year ended December 31, 2012.

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 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 financial statements or related disclosures.

Income Tax Disclosure [Abstract]

Income Taxes

NOTE 10: INCOME TAXES

Each interim period is considered an integral part of the annual period and, accordingly, we measure our tax expense using an estimated annual effective tax rate. An enterprise is required, at the end of each interim reporting period, to make its best estimate of the annual effective tax rate for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, as adjusted for discrete taxable events that occur during the interim period.

Our effective tax rate for the three and nine months ended September 30, 2013 was 33.2% and 28.2%, respectively. Our effective tax rate for the three and nine months ended September 30, 2012 was 34.4% and 32.6%, respectively. For the three and nine months ended September 30, 2013, the effective tax rate is less than the federal statutory rate primarily due to earnings in jurisdictions outside the United States, where our effective tax rate is lower, which was partially offset by state income taxes, non-deductible stock compensation and accruals on uncertain tax positions. The decrease in the effective tax rate for 2013 compared to the 2012 rate was primarily due to an increase in earnings in jurisdictions outside the United States as well as an internal restructuring that occurred during the fourth quarter of 2012. This restructuring was undertaken within our non-US operations to align our global structure for more efficient treasury management and global cash deployment. Additionally, the rate for the three months ended September 30, 2013 includes a release of an accrual for uncertain tax benefits in the amount of $1.8 million as a result of receiving a Private Letter Ruling from a taxing authority.

Our policy is to recognize accrued interest and penalties related to unrecognized tax benefits and income tax liabilities as part of our income tax expense. As of September 30, 2013, accrued interest is $0.9 million, net of federal benefit, and no penalties have been accrued.

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 will file as part of a unitary combined group with Expedia for certain state tax returns for the 2012 tax period.

As of September 30, 2013, the Company’s tax years for 2009 through 2012 are subject to examination by the tax authorities in the United States, various states, and foreign jurisdictions. By virtue of previously filed consolidated income tax returns filed with Expedia, we are routinely under audit. We are currently under an IRS audit for the 2009 and 2010 tax years, and have various ongoing state income tax audits. As of September 30, 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.

The following table presents the summary purchase price allocation initially recorded for all 2013 acquisitions on our consolidated balance sheets at the respective acquisition dates (in thousands):

	Total
Net liabilities (1)	$	(14,195	)
Goodwill (2)		34,137
Intangible assets (3)		16,944
Deferred tax liability		(1,352	)
Total purchase price consideration (4)	$	35,534

(1) Includes cash acquired of $2.9 million.

(2) 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 $17.4 million is expected to be deductible for tax purposes.

(3) Identifiable definite-lived intangible assets were comprised of developed technology of $1.6 million, trade names of $7.0 million, customer relationships of $7.9 million, and non-compete agreements of $0.4 million. The overall weighted-average life of the identifiable definite-lived intangible assets acquired in the purchase of the companies was 8.3 years, which will be amortized on a straight-line basis over their estimated useful lives from acquisition date.

(4) Subject to adjustment based on (i) final working capital adjustment calculations, and (ii) indemnification obligations of the acquired company stockholders.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]

Stock Based Awards and Other Equity Instruments

NOTE 3: STOCK BASED AWARDS AND OTHER EQUITY INSTRUMENTS

Stock-based compensation expense relates primarily to expense for restricted stock units (“RSUs”) and stock options. Our outstanding RSUs and stock options generally vest over four years.

For the three and nine months ended September 30, 2013, we recognized total stock-based compensation expense of $11.7 million and $35.5 million, respectively. The total income tax benefit related to stock-based compensation expense was $4.4 million and $13.8 million for the three and nine months ended September 30, 2013, respectively. For the three and nine months ended September 30, 2012, we recognized total stock-based compensation expense of $8.5 million and $19.9 million, respectively. The total income tax benefit related to stock-based compensation expense was $3.2 million and $7.2 million for the three and nine months ended September 30, 2012, respectively.

TripAdvisor, Inc. 2011 Stock and Annual Incentive Plan, As Amended

On December 20, 2011, our 2011 Stock and Annual Incentive Plan became effective. 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. 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.

2013 Stock Option Activity

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. Stock options granted during the first nine months of 2013 generally have a term of ten years from the date of grant and generally vest over a four-year service period.

During the nine months ended September 30, 2013, we granted 2,776,247 primarily service-based stock options under the 2011 Incentive Plan with a weighted average grant-date fair value per option of $28.11. We will amortize the fair value, 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. We use historical data to estimate pre-vesting option 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.

A summary of the status and activity for stock option awards relating to our common stock for the nine months ended September 30, 2013, is presented below:

(1) Inclusive of 168,795 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 September 30, 2013 was $75.84.

The estimated fair value of the options granted under the 2011 Incentive Plan was 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 estimated the 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 of a peer group was based upon the relatively short period of availability of data on our common stock. We estimated 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.

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

	Three months ended September 30,						Nine months ended September 30,
	2013			2012			2013			2012
Risk free interest rate		1.83	%		0.90	%		1.40	%		1.03	%
Expected term (in years)		5.80			6.25			6.05			6.22
Expected volatility		49.62	%		54.78	%		50.81	%		53.54	%
Expected dividend yield		0	%		0	%		0	%		0	%

2013 RSU Activity

During the nine months ended September 30, 2013, we granted 1,083,082 primarily service-based RSUs under the 2011 Incentive Plan for which the fair value was measured based on the quoted price of our common stock at the date of grant. We will amortize the fair value, 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.

The following table presents a summary of RSU activity on our common stock:

	RSUs Outstanding		Weighted Average Grant- Date Fair Value Per Share		Aggregate Intrinsic Value
	(In thousands)				(In thousands)
Unvested RSUs outstanding as of January 1, 2013		446	$	26.11

(1) Inclusive of 127,199 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.

A summary of the unrecognized compensation expense, net of estimated forfeitures, and the weighted average period remaining at September 30, 2013 related to our non-vested stock options and RSU awards is presented below (in thousands, except year information):

Organization and Basis of Presentation

NOTE 1: ORGANIZATION AND BASIS OF PRESENTATION

We refer to TripAdvisor, Inc. and our wholly-owned subsidiaries as “TripAdvisor,” “the Company,” “us,” “we” and “our” in these notes to the unaudited consolidated 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.

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 (including hotels, bed and breakfasts, 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 media brands: www.airfarewatchdog.com, www.bookingbuddy.com, www.cruisecritic.com, www.everytrail.com, www.familyvacationcritic.com, www.flipkey.com, www.gateguru.com, www.holidaylettings.co.uk, www.holidaywatchdog.com, www.independenttraveler.com, www.jetsetter.com, www.niumba.com, www.onetime.com, www.seatguru.com, www.smartertravel.com, www.tingo.com, www.travelpod.com, www.virtualtourist.com, www.whereivebeen.com, and www.kuxun.cn, 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 selling room nights on our transactional sites, and other revenue including licensing our content to third-parties. We have one 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.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared by us in accordance with generally accepted accounting principles, or GAAP, for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in financial statements prepared under generally accepted accounting principles for complete periods have been condensed or omitted pursuant to such regulations. In the opinion of management, all adjustments considered necessary for a fair presentation of our financial position, results of operations and cash flows have been included. All such adjustments are of a normal recurring nature. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2012 in our Annual Report on Form 10-K. The results for interim periods are not necessarily indicative of the results to be expected for the full year. The financial statements and related financial disclosures have been presented on a consolidated basis.

Consolidation

Our consolidated financial statements include the accounts of 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 noncontrolling interest in our consolidated financial statements to recognize the minority ownership interest in our consolidated subsidiaries. Noncontrolling interest in the earnings and losses of consolidated subsidiaries represent the share of net income or loss allocated to members or partners in our consolidated entities. Significant intercompany transactions between the TripAdvisor consolidated entities and accounts have been eliminated.

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. Although we currently operate at a loss in the Chinese market, our variable interest entities are not material for all periods presented.

Accounting Estimates

We use estimates and assumptions in the preparation of our consolidated 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 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 financial statements include revenue recognition; recoverability of long-lived assets, valuation and impairment of marketable securities, intangible assets and goodwill; income taxes; useful lives of property and equipment; purchase accounting and stock-based compensation.

Reclassifications

We have reclassified certain amounts related to our prior period results to conform to our current period presentation.

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.

Acquisitions

NOTE 6: ACQUISITIONS

During the nine months ended September 30, 2013, we completed five acquisitions for total cash consideration paid of $31.5 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; and GateGuru, a mobile app with flight and airport information around the world, 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. Acquisition-related costs were expensed as incurred and were not significant.

The following table presents the summary purchase price allocation initially recorded for all 2013 acquisitions on our consolidated balance sheets at the respective acquisition dates (in thousands):

	Total
Net liabilities (1)	$	(14,195	)
Goodwill (2)		34,137
Intangible assets (3)		16,944
Deferred tax liability		(1,352	)
Total purchase price consideration (4)	$	35,534

(1) Includes cash acquired of $2.9 million.

(2) 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 $17.4 million is expected to be deductible for tax purposes.

(3) Identifiable definite-lived intangible assets were comprised of developed technology of $1.6 million, trade names of $7.0 million, customer relationships of $7.9 million, and non-compete agreements of $0.4 million. The overall weighted-average life of the identifiable definite-lived intangible assets acquired in the purchase of the companies was 8.3 years, which will be amortized on a straight-line basis over their estimated useful lives from acquisition date.

(4) Subject to adjustment based on (i) final working capital adjustment calculations, and (ii) indemnification obligations of the acquired company stockholders.

Our consolidated financial statements include the operating results of all acquired businesses from the date of each acquisition. Pro forma results of operations for all 2013 acquisitions have not been presented in our consolidated financial statements as the financial impact to our consolidated financial statements both individually and in aggregate, are not material. There were no acquisitions completed during the nine months ended September 30, 2012.

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 (including hotels, bed and breakfasts, 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 media brands: www.airfarewatchdog.com, www.bookingbuddy.com, www.cruisecritic.com, www.everytrail.com, www.familyvacationcritic.com, www.flipkey.com, www.gateguru.com, www.holidaylettings.co.uk, www.holidaywatchdog.com, www.independenttraveler.com, www.jetsetter.com, www.niumba.com, www.onetime.com, www.seatguru.com, www.smartertravel.com, www.tingo.com, www.travelpod.com, www.virtualtourist.com, www.whereivebeen.com, and www.kuxun.cn, 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 selling room nights on our transactional sites, and other revenue including licensing our content to third-parties. We have one 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.

Basis of Presentation

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared by us in accordance with generally accepted accounting principles, or GAAP, for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in financial statements prepared under generally accepted accounting principles for complete periods have been condensed or omitted pursuant to such regulations. In the opinion of management, all adjustments considered necessary for a fair presentation of our financial position, results of operations and cash flows have been included. All such adjustments are of a normal recurring nature. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2012 in our Annual Report on Form 10-K. The results for interim periods are not necessarily indicative of the results to be expected for the full year. The financial statements and related financial disclosures have been presented on a consolidated basis.

Consolidation

Consolidation

Our consolidated financial statements include the accounts of 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 noncontrolling interest in our consolidated financial statements to recognize the minority ownership interest in our consolidated subsidiaries. Noncontrolling interest in the earnings and losses of consolidated subsidiaries represent the share of net income or loss allocated to members or partners in our consolidated entities. Significant intercompany transactions between the TripAdvisor consolidated entities and accounts have been eliminated.

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. Although we currently operate at a loss in the Chinese market, our variable interest entities are not material for all periods presented.

Accounting Estimates

Accounting Estimates

We use estimates and assumptions in the preparation of our consolidated 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 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 financial statements include revenue recognition; recoverability of long-lived assets, valuation and impairment of marketable securities, intangible assets and goodwill; income taxes; useful lives of property and equipment; purchase accounting and stock-based compensation.

Reclassifications

Reclassifications

We have reclassified certain amounts related to our prior period results to conform to our current period presentation.

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.

Deferred Merchant Payables

Deferred Merchant Payables

We receive cash from travelers at the time of booking related to our 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 September 30, 2013, our deferred merchant payables balance was $28.6 million and for the nine months ended September 30, 2013, the related transactions generated positive operating cash flow of $12.8 million. A payable balance of $14.5 million was acquired with our business acquisitions during the nine months ended September 30, 2013. For additional information on our business acquisitions refer to “Note 6—Acquisitions” below. The deferred merchant payables balance at December 31, 2012 was $1.3 million.

There have been no material changes or other additions to our significant accounting policies since December 31, 2012. For additional information about our critical accounting policies and estimates, refer to “Note 2—Significant Accounting Policies,” included in our Annual Report on Form 10-K for the year ended December 31, 2012.

Recently Adopted Accounting Pronouncements

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 financial statements or related disclosures.

NOTE 5: DEBT

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 September 30, 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 $30 million were made during the nine months ended September 30, 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 September 30, 2013, there are no outstanding borrowings under our Revolving Credit Facility. During the three and nine months ended September 30, 2013, we recorded total interest and commitment fees on our Credit Agreement of $1.8 million and $5.9 million, respectively, to interest expense, on our consolidated statement of operations. During the three and nine months ended September 30, 2012, we recorded total interest and commitment fees on our Credit Agreement of $2.1 million and $6.5 million, respectively, to interest expense on our consolidated statements of operations. All unpaid interest and commitment fee amounts as of September 30, 2013 and December 31, 2012 were not material.

Total outstanding borrowings under the Credit Agreement consist of the following (in thousands):

2014	$	40,000
2015	$	40,000

Total	$	350,000

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 September 30, 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 September 30, 2013 and December 31, 2012, we had short-term borrowings outstanding of $26.2 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 nine months ended September 30, 2013, we made a payment inclusive of interest of RMB 68,283,570 (approximately $10.9 million). We currently have $11.9 million of outstanding borrowings from the Chinese Credit Facility—BOA as of September 30, 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 September 30, 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 nine months ended September 30, 2013, we made a payment inclusive of interest of RMB 24,281,546 (approximately $3.9 million). We currently have $14.3 million of outstanding borrowings from the Chinese Credit Facility—JPM as of September 30, 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 September 30, 2013.

(1) Total cash does not include $40.4 million of marketable securities which were sold during the period, but had not yet settled on report date. This amount was recorded to Receivable—sale of marketable securities on our consolidated balance sheet at September 30, 2013. This cash was received on October 1, 2013.

Our cash and cash equivalents consist of cash on hand in global financial institutions, money market funds and marketable securities with contractual maturity dates of 90 days or less at the date purchased. The remaining contractual maturity dates of our long-term marketable securities range from one to three years and our short-term marketable securities include contractual maturity dates that were greater than 90 days at the date purchased and have 12 months or less remaining at September 30, 2013.

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 was derived from quoted prices in active markets for identical assets or liabilities. Investments in U.S. Treasury securities are considered “Level 2” valuations because we have access to quoted prices, but do not have visibility into the volume and frequency of trading for all investments. Fair values for our U.S. agency securities, commercial paper, corporate securities, certificates of deposit and municipal securities are considered “Level 2” valuations because they are obtained from pricing sources for identical or comparable instruments, rather than direct observations of quoted prices in active markets.

There were no material realized gains or losses related to sales of our marketable securities for the three and nine months ended September 30, 2013 and 2012.

As of September 30, 2013, we have marketable securities with a total fair value of $165.1 million in a total gross unrealized loss position of $0.4 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 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 nine months ended September 30, 2013 and 2012, we did not recognize any impairment charges. We did not have any investments in marketable securities that were in a continuous unrealized loss position for 12 months or greater at September 30, 2013 or December 31, 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 $1.2 million and $0.6 million for the three and nine month periods ended September 30, 2013, respectively, related to our forward contracts in our consolidated statement of operations in Other, net. We recorded a net loss of $0.3 million for the three and nine month periods ended September 30, 2012, respectively, related to our forward contracts in our consolidated statement 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.

The following tables show the fair value and notional principal amounts of our outstanding or unsettled derivative instruments that are not designated as hedging instruments (in thousands):

	Balance Sheet Caption	September 30, 2013
		Fair Value of Derivative(2)				U.S. Dollar Notional
		Asset		Liability
Foreign exchange-forward contracts (current)	Accrued and other current liabilities (1)	$	—	$	160	$	6,604

		Asset		Liability
Foreign exchange-forward contracts (current)	Accrued and other current liabilities (1)	$	—	$	64	$	2,710

(1) Derivative contracts address foreign exchange fluctuations for the Euro versus the U.S. dollar.

(2) The fair value of our derivatives are 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.

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, related party receivables, 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 our consolidated balance sheets as of September 30, 2013 and December 31, 2012. The carrying value of the long-term borrowings outstanding on our Credit Agreement bears interest at a variable rate and therefore is also considered to approximate fair value.

We did not have any Level 3 assets or liabilities for the periods ended September 30, 2013 and December 31, 2012.

Equity [Abstract]

Stockholders' Equity

NOTE 11: STOCKHOLDERS’ EQUITY

Common Stock and Class B Common Stock

Our authorized common stock consists of 1.6 billion shares of common stock with par value of $0.001 per share, and 400 million shares of Class B common stock with par value of $0.001 per share. Both classes of common stock qualify for and share equally in dividends, if declared by our Board of Directors. Common stock is entitled to one vote per share and Class B common stock is entitled to 10 votes per share on most matters. Holders of TripAdvisor common stock, acting as a single class, are entitled to elect a number of directors equal to 25% percent of the total number of directors, rounded up to the next whole number, which was three directors as of September 30, 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 131,372,883 and 129,289,174 shares of common stock issued and outstanding, respectively, at September 30, 2013 and 12,799,999 shares of Class B common stock issued and outstanding at September 30, 2013.

Preferred Stock

In addition to common stock, we are authorized to issue up to 100 million preferred shares, with $ 0.001 par value per share, with terms determined by our Board of Directors, without further action by our stockholders. At September 30, 2013, no preferred shares had been issued.

Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss is primarily comprised of accumulated foreign currency translation adjustments, as follows (in thousands):

	September 30, 2013			December 31, 2012
Net unrealized loss on securities, net of tax (1)	$	(151	)	$	(104	)
Cumulative foreign currency translation adjustments (2)		(1,157	)		(765	)

(1) Net of unrealized tax benefits of $0.1 million and $0.1 million at September 30, 2013 and December 31, 2012, respectively.

(2) Our foreign subsidiary earnings are considered indefinitely reinvested; therefore; deferred taxes are not provided on foreign currency translation adjustments.

Treasury Stock

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. The repurchase program has no expiration date but may be suspended or terminated by the Board of Directors at any time. Our Board of Directors will determine the price, timing, amount and method of such repurchases based on its evaluation of market conditions and other factors, and any shares repurchased will be in compliance with applicable legal requirements, at prices determined to be attractive and in the best interests of both the Company and its stockholders.

During the nine month period ended September 30, 2013, we repurchased 2,083,709 shares of outstanding common stock under the share repurchase program at an aggregate cost of $142.3 million, of which $4.8 million remains payable at September 30, 2013. As of September 30, 2013, from the authorized share repurchase program granted by the Board of Directors we have remaining $107.7 million to repurchase shares of our common stock.

Dividends

During the period January 1, 2013 through September 30, 2013, our Board of Directors did not declare any dividends on our outstanding common stock and do not expect to pay any cash dividends for the foreseeable future.

NOTE 14: RELATED PARTY TRANSACTIONS

Expedia

Subsequent to the Spin-Off, we remained a related party with Expedia due to common ownership of our shares and shares of Expedia by Liberty Interactive Corporation.

Related-party revenue from Expedia was $56.2 million and $171.0 million for the three and nine months ended September 30, 2013, respectively, and was $56.9 million and $164.2 million for the three and nine months ended September 30, 2012, 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. Related-party revenue represented 22.0% and 23.4% of our total revenue for the three and nine months ended September 30, 2013, respectively, and 26.7% and 27.7% of our total revenue for the three and nine months ended September 30, 2012, respectively. Other related-party operating expenses which were included within selling and marketing expense were $1.8 million and $4.9 million for the three and nine months ended September 30, 2013, respectively, and were $1.7 million and $5.2 million for the three and nine months ended September 30, 2012, respectively, which primarily consisted of marketing expense for exit windows. The net related party receivable balances with Expedia reflected in our consolidated balance sheets as of September 30, 2013 and December 31, 2012 were $33.9 million and $24.0 million, respectively.

Liberty Interactive Corporation

As of September 30, 2013, Liberty Interactive Corporation, or 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 as of September 30, 2013.

We had no related party transactions with Liberty during the nine months ended September 30, 2013 and 2012, respectively.

Segment Reporting [Abstract]

Segment Information

NOTE 12: SEGMENT INFORMATION

We have one reportable segment: TripAdvisor. We determined our segment based on how our chief operating decision maker manages our business, makes operating decisions and evaluates operating performance. 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 Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” below.

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 (in thousands):

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

NOTE 13: EARNINGS PER SHARE

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. For the three and nine months ended September 30, 2013 and 2012, we computed the weighted average number of common shares outstanding during the period using the total of common stock and Class B common stock outstanding as of December 31, 2012 and 2011, respectively, plus the weighted average of any additional shares issued and outstanding less the weighted average of any treasury shares repurchased, during the three and nine months ended September 30, 2013 and 2012, respectively.

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. For the three and nine months ended September 30, 2013 and 2012, 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, (ii) if dilutive, the incremental weighted average common stock that we would issue upon the assumed exercise of common equivalent shares related to stock options and stock warrants and the vesting of restricted stock units using the treasury stock method during the three and nine months ended September 30, 2013 and 2012, respectively, 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.

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):

Diluted EPS	$	0.38	$	0.41	$	1.27	$	1.14

The following potential common shares related to stock options 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 (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2013(1)		2012(2)		2013(1)		2012(2)

RSUs		47		—		32		20
Total		1,407		4,921		2,591		3,604

(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 as of September 30, 2013; 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 and RSUs representing the right to acquire 110,000 shares and 400,000 shares of common stock for which all targets required to trigger vesting had not been achieved as of September 30, 2012; 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.
