Organization and Basis of Presentation [Abstract]

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 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. A one-for-two reverse stock split of outstanding Expedia capital stock occurred immediately prior to the Spin-Off, with cash paid in lieu of fractional shares. In connection with the Spin-Off, Expedia contributed or transferred all of the subsidiaries and assets relating to Expedia’s TripAdvisor Media Group, which were comprised of the TripAdvisor Holdings, LLC combined financial statements, to TripAdvisor and TripAdvisor or one of its subsidiaries 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 (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 29 countries, including in China under the brand daodao.com. Beyond travel-related content, TripAdvisor websites also include links to the websites of our travel advertisers allowing travelers to directly book their travel arrangements. In addition to the flagship TripAdvisor brand, we manage and operate 20 other travel brands, connected by the common goal of providing comprehensive travel planning resources across the travel sector. We derive substantially all of our revenue from advertising, primarily through click-based advertising and display-based advertising sales. In addition, we earn revenue through a combination of subscription-based offerings from our Business Listings and Vacation Rental products, transaction revenue from selling room nights on our transactional sites, including SniqueAway and Tingo, 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 filed with the Securities and Exchange Commission (“SEC”) in our Annual Report on Form 10-K on February 15, 2013. 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.

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.

The entire disclosure for organization, consolidation and basis of presentation of financial statements disclosure.

SIGNIFICANT ACCOUNTING POLICIES

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES

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 disclosure.

There have been no material changes 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 filed on February 15, 2013 for the year ended December 31, 2012.

Stock Based Awards and Other Equity Instruments [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 months ended March 31, 2013 and 2012, we recognized total stock-based compensation expense of $13.6 million and $4.7 million, respectively. The total income tax benefit related to stock-based compensation expense was $5.3 million and $1.6 million for the three months ended March 31, 2013 and 2012, respectively.

TripAdvisor, Inc. 2011 Stock and Annual Incentive Plan

On December 20, 2011, the 2011 Incentive Plan became effective. A summary of certain important features of the 2011 Incentive Plan can be found in “Note 4—Stock Based Awards and Other Equity Instruments,” in the Notes to our Consolidated Financial Statements in Item 8 of our Annual Report on Form 10-K filed on February 15, 2013 for the year ended December 31, 2012. 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 which is incorporated by reference in our Annual Report on Form 10-K as Exhibit 4.3.

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 three months of 2013 have a term of ten years from the date of grant and generally vest over a four-year service period.

During the three months ended March 31, 2013, we granted 1,414,861 primarily service based stock options under the 2011 Incentive Plan with a weighted average grant-date fair value per option of $22.68. 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 three months ended March 31, 2013, is presented below:


	Options Outstanding		Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Life		Aggregate Intrinsic Value
	(In thousands)				(In years)		(In thousands)
Options outstanding at January 1, 2013		8,654	$	31.41
Granted		1,415		45.42
Exercised		302		21.39			$	7,059
Cancelled		123		33.34


Options outstanding at March 31, 2013		9,644	$	33.76		6.2	$	180,944


Exercisable as of March 31, 2013		4,313	$	28.29		3.9	$	104,492


Vested and expected to vest after March 31, 2013		9,010	$	33.19		6.2	$	172,052

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 March 28, 2013 was $52.52.

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 historical stock price volatility 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.

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


	Three months ended March 31, 2013
Risk free interest rate		1.07	%
Expected term (in years)		6.25
Expected volatility		51.72	%
Expected dividend yield		0	%

There were no stock options granted in the first three months ending March 31, 2012.

2013 RSU Activity

During the three months ended March 31, 2013, we granted 860,072 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 of $45.26. 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
	(In thousands)
Unvested RSUs outstanding as of January 1, 2013		446	$	26.11
Granted		860		45.26
Vested and released (1)		296		21.70
Cancelled		15		34.22


Unvested RSUs outstanding as of March 31, 2013		995	$	42.99

(1)	Inclusive of 111,918 RSUs withheld to satisfy minimum tax withholding requirements.

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


	Stock Options		RSUs
Unrecognized compensation expense (net of forfeitures)	$	82,187	$	30,558
Weighted average period remaining (in years)		3.1		3.7

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.

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

As of March 31, 2013, we have marketable securities with a total fair value of $214.7 million in a total gross unrealized loss position of $0.2 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 three months ended March 31, 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 March 31, 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 gain in Other, net of $0.8 million for the three months ended March 31, 2013 related to our forward contracts in our consolidated statement of operations. The net cash received or paid related to our derivative instruments are classified as operating in our consolidated statements of cash flows, which is based on the objective of the derivative instruments. No derivative instruments were entered into or settled during the three months ended March 31, 2012.

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 at March 31, 2013 and December 31, 2012 (in thousands):


	Balance Sheet Caption	March 31, 2013
	Balance Sheet Caption	Fair Value of Derivative (2)				U.S. Dollar Notional

		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, short-term debt, accrued and other current liabilities and long-term debt. With the exception of long-term debt, the carrying amount approximates fair value because of the short maturity of these instruments as reported on the unaudited consolidated balance sheet as of March 31, 2013 and December 31, 2012. The carrying value of the long-term borrowings outstanding on our Credit Agreement bear interest at a variable rate and therefore is also considered to approximate fair value.

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

NOTE 5: DEBT

Term Loan Facility Due 2016 and Revolving Credit Facility

Overview

On December 20, 2011, in connection with the Spin-Off, we entered into 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 175 basis points, or the Eurocurrency Spread, or the alternate base rate (“ABR”) plus 75 basis points, and undrawn amounts are currently subject to a commitment fee of 30 basis points.

As of March 31, 2013 we are using a one-month interest period Eurocurrency Spread which is approximately 2.0% 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. A principal payment of $10 million was made during the three months ended March 31, 2013.

The Revolving Credit Facility includes $40 million of borrowing capacity available for letters of credit and $40 million for borrowings on same-day notice. Immediately following the Spin-Off, $10 million was drawn down under the Revolving Credit Facility, which was repaid during the three months ended March 31, 2012. As of March 31, 2013, there are no outstanding borrowings under our Revolving Credit Facility.

During the three months ended March 31, 2013 and 2012, we recorded total interest and commitment fees on our Credit Agreement of $2.1 million and $2.3 million, respectively, to interest expense on our consolidated statement of operations. All unpaid interest and commitment fee amounts as of March 31, 2013 and December 31, 2012 were not material.

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


	March 31, 2013
Short-Term Debt:
Revolving Credit Facility	$	—
Term Loan		40,000


Total Short-Term Borrowings	$	40,000


Long-Term Debt:
Term Loan	$	330,000


Total Long-Term Borrowings	$	330,000

The remaining future minimum principal payment obligations due under the Credit Agreement related to our Term Loan is as follows as of March 31, 2013 (in thousands):


	Payment Amount
2013	$	30,000
2014	$	40,000
2015	$	40,000
2016	$	260,000


Total	$	370,000

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 or repurchase our capital stock, 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 March 31, 2013 we believe we are in compliance with all of our debt covenants.

The full text of the Credit Agreement is incorporated by reference to Exhibit 4.2 of our Annual Report on Form 10-K filed on February 15, 2013 for the year ending December 31, 2012.

Chinese Credit Facilities

In addition to our borrowings under the Credit Agreement, we maintain our Chinese Credit Facilities. As of March 31, 2013 and December 31, 2012, we had $21.3 million and $32.1 million of short term borrowings outstanding, 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 three months ended March 31, 2013, we made a payment inclusive of interest of RMB 68,283,570 (approximately $10.9 million). We currently have $11.0 million of outstanding borrowings from this credit facility as of March 31, 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 March 31, 2013.

In addition, during April 2012, certain of our Chinese subsidiaries entered into a RMB 125,000,000 (approximately $20 million) one-year revolving credit facility with J.P. Morgan Chase Bank (“Chinese Credit Facility-JPM”). During the three months ended March 31, 2013, we made a payment inclusive of interest of RMB 24,281,546 (approximately $3.9 million). We currently have $10.3 million of outstanding borrowings from this credit facility as of March 31, 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 March 31, 2013.

Commitments and Contingencies [Abstract]

COMMITMENTS AND CONTINGENCIES

NOTE 6: COMMITMENTS AND CONTINGENCIES

There have been no material changes to our commitments and contingencies 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 filed on February 15, 2013 for the year ended December 31, 2012.)

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

Income Taxes [Abstract]

INCOME TAXES

NOTE 7: 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 months ended March 31, 2013 and 2012 was 26.2% and 32.3%, respectively. For the three months ended March 31, 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.

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 March 31, 2013, accrued interest is $0.7 million, net of federal benefit, and no penalties have been accrued. We do not anticipate any material releases in the next twelve months.

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 may be considered to have a unitary relationship with Expedia from January 1, 2012 through December 11, 2012 for state income tax purposes. Consequently, we may file as part of a unitary combined group with Expedia for certain state tax returns for 2012.

As of March 31, 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 March 31, 2013, no material assessments have resulted from these audits. These audits include questioning the timing and the amount of income and deductions and the allocation of income among various tax jurisdictions. Annual tax provisions include amounts considered sufficient to pay assessments that may result from the examination of prior year returns. We are no longer subject to tax examinations by tax authorities for years prior to 2005.

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 is currently two directors. 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 130,544,816 shares of common stock and 12,799,999 shares of Class B common stock issued and outstanding at March 31, 2013.

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 but may be suspended or terminated by the Board of Directors at any time. The Executive Committee of 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.

As of March 31, 2013, we have not repurchased any shares of outstanding common stock.

We define Adjusted EBITDA as net income (loss) plus: (1) provision for income taxes; (2) other (income) expense, net; (3) depreciation of property and equipment, including internal use software and website development; (4) amortization of intangible assets; (5) stock-based compensation; and (6) non-recurring expenses. Such amounts are detailed in our segment reconciliation below. In addition, please see our discussion of Adjusted EBITDA in the section entitled “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

3 Months Ended

Mar. 31, 2013

Earnings Per Share [Abstract]

EARNINGS PER SHARE

NOTE 10: 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 months ended March 31, 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 during the three months ended March 31, 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 months ended March 31, 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 months ended March 31, 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 March 31,
	2013		2012
Numerator:
Net income attributable to TripAdvisor	$	62,299	$	48,111
Denominator:
Weighted average shares used to compute Basic EPS		143,063		133,754
Weighted average effect of dilutive securities:
Stock options		1,401		1,132
RSUs		191		194
Stock warrants		—		1,078


Weighted average shares used to compute Diluted EPS		144,655		136,158


Basic EPS	$	0.44	$	0.36
Diluted EPS	$	0.43	$	0.35

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 March 31,
	2013(1)		2012(2)
Stock options		4,577		1,821

RSUs		—		60


Total		4,577		1,881

(1)

These totals do not include performance based options representing the right to acquire 210,000 shares of common stock for which all targets required to trigger vesting have not been achieved as of March 31, 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 RSUs representing the right to acquire 400,000 shares of common stock for which all targets required to trigger vesting had not been achieved as of March 31, 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.

RELATED PARTY TRANSACTIONS

NOTE 11: RELATED PARTY TRANSACTIONS

Expedia

Subsequent to the Spin-Off, we remain a related party with Expedia due to common ownership, and continue to work together pursuant to various commercial agreements between subsidiaries of TripAdvisor, on the one hand, and subsidiaries of Expedia, on the other hand.

Related-party revenue from Expedia of $60.5 million and $51.6 million for the three months ended March 31, 2013 and 2012, respectively, 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 26.3% and 28.1% of our total revenue for the three months ended March 31, 2013 and 2012, respectively. Other related-party operating expenses which were included within selling and marketing expense were $1.8 million and $2.0 million for the three months ended March 31, 2013 and 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 March 31, 2013 and December 31, 2012 were $37.9 million and $24.0 million, respectively.

Liberty Interactive Corporation

As of March 31, 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 13.9% 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 21.6% 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 56.5% of our voting power.

We had no related party transactions with Liberty during the three months ended March 31, 2013 and 2012, respectively.

Organization and Basis of Presentation (Policies)	3 Months Ended
Organization and Basis of Presentation (Policies)	Mar. 31, 2013
Organization and Basis of Presentation [Abstract]
Description of Business	*Description of Business* TripAdvisor is an online travel company, empowering users to plan and have the perfect trip. TripAdvisor’s travel research platform aggregates reviews and opinions of members about destinations, accommodations (hotels, 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 29 countries, including in China under the brand daodao.com. Beyond travel-related content, TripAdvisor websites also include links to the websites of our travel advertisers allowing travelers to directly book their travel arrangements. In addition to the flagship TripAdvisor brand, we manage and operate 20 other travel brands, connected by the common goal of providing comprehensive travel planning resources across the travel sector. We derive substantially all of our revenue from advertising, primarily through click-based advertising and display-based advertising sales. In addition, we earn revenue through a combination of subscription-based offerings from our Business Listings and Vacation Rental products, transaction revenue from selling room nights on our transactional sites, including SniqueAway and Tingo, 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 filed with the Securities and Exchange Commission (“SEC”) in our Annual Report on Form 10-K on February 15, 2013. 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.
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.
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 disclosure. There have been no material changes 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 filed on February 15, 2013 for the year ended December 31, 2012.

- Definition

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.
