Significant Accounting Policies [Abstract] |
SIGNIFICANT ACCOUNTING POLICIES | NOTE 2: SIGNIFICANT ACCOUNTING POLICIES Consolidation Our consolidated and combined 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 our investments in entities that we do not control, but over which we have the ability to exercise significant influence, using the equity method. We record noncontrolling interest in our consolidated and combined financial statements to recognize the minority ownership interest in our consolidated 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. Our variable interest entities are not material for all periods presented. Accounting Estimates We use estimates and assumptions in the preparation of our consolidated and combined financial statements in accordance with GAAP. Our estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our consolidated and combined financial statements. These estimates and assumptions also affect the reported amount of net income or loss during any period. Our actual financial results could differ significantly from these estimates. The significant estimates underlying our consolidated and combined financial statements include revenue recognition; recoverability of long-lived assets and investments, intangible assets and goodwill; income taxes; useful lives of property and equipment; purchase accounting and stock-based compensation. Reclassifications Certain reclassifications have been made to conform the prior period to the current presentation, which include the reclassifications of our redeemable noncontrolling interest on the consolidated balance sheets from accrued expenses and other current liabilities to the mezzanine section and the reclassification of accrued marketing costs from accounts payable to accrued expenses and other current liabilities on our consolidated balance sheets. These reclassifications had no net effect on our consolidated and combined financial statements. Revenue Recognition We recognize revenue from the advertising services rendered when the following four revenue recognition criteria are met: persuasive evidence of an arrangement exists, services have been rendered, the price is fixed or determinable, and collectability is reasonably assured. Click-based Advertising. Revenue is derived primarily from click-through fees charged to our travel partners for traveler leads sent to the travel partners’ website. We record revenue from click-through fees after the traveler makes the click-through to the travel partners’ websites. Display and Other Advertising. We recognize display advertising revenue ratably over the advertising period or upon delivery of advertising impressions, depending on the terms of the advertising contract. Subscription-based revenue is recognized ratably over the related subscription period. We recognize revenue from all other sources either upon delivery or when we provide the service. Deferred revenue, which primarily relates to our subscription-based programs, is recorded when payments are received in advance of our performance as required by the underlying agreements. Cost of Revenue Cost of revenue consists of expenses that are closely correlated or directly related to revenue generation, including ad serving fees, flight search fees, credit card fees and data center costs. Selling and Marketing Sales and marketing expenses primarily consist of direct costs, including search engine marketing, or SEM, other traffic acquisition costs, syndication costs and affiliate program commissions, brand advertising and public relations. In addition, our indirect sales and marketing expense consists of personnel and overhead expenses, including salaries, commissions, benefits, stock-based compensation expense and bonuses for sales, sales support, customer support and marketing employees. Technology and Content Technology and content expenses consist of personnel and overhead expenses, including salaries and benefits, stock-based compensation expense and bonuses for salaried employees and contractors engaged in the design, development, testing and maintenance of our website. Other costs include licensing and maintenance expense. General and Administrative General and administrative expenses consist primarily of personnel and related overhead costs, including executive leadership, finance, legal and human resource functions and stock-based compensation as well as professional service fees and other fees including audit, legal, tax and accounting, and other costs including bad debt expense and our charitable foundation costs. Cash, Cash Equivalents and Marketable Securities Our cash equivalents consist of highly liquid investments with maturities of 90 days or less at the date of purchase. Our marketable debt and equity securities have been classified and accounted for as available-for-sale. We determine the appropriate classification of our investments at the time of purchase and reevaluate the designations at each balance sheet date. We invest in highly-rated securities, and our investment policy limits the amount of credit exposure to any one issuer, industry group and currency. The policy requires investments to be investment grade, with the primary objective of minimizing the potential risk of principal loss and providing liquidity of investments sufficient to meet our operating and capital spending requirements and debt repayments. We classify our marketable debt securities as either short-term or long-term based on each instrument’s underlying contractual maturity date and as to whether and when we intend to sell a particular security prior to its maturity date. Marketable debt securities with maturities greater than 90 days at the date of purchase and 12 months or less remaining at the balance sheet date will be classified as short-term and marketable debt securities with maturities greater than 12 months from the balance sheet date will generally be classified as long-term. We classify our marketable equity securities, limited to money market funds and mutual funds, as either short-term or long-term based on the nature of each security and its availability for use in current operations. Our marketable debt and equity securities are carried at fair value, with the unrealized gains and losses, net of taxes, reported in accumulated other comprehensive income (loss) as a component of shareholders’ equity. Fair values are determined for each individual security in the investment portfolio. Realized gains and losses on the sale of securities are determined by specific identification of each security’s cost basis. We may sell certain of our marketable securities prior to their stated maturities for strategic reasons including, but not limited to, anticipation of credit deterioration and liquidity and duration management. The weighted average maturity of our total invested cash shall not exceed 12 months, and no security shall have a final maturity date greater than three years. When evaluating an investment for other-than-temporary impairment, we review factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer and any changes thereto, and our intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of the investment’s cost basis. Once a decline in fair value is determined to be other than temporary, an impairment charge is recorded and a new cost basis in the investment is established. If we do not intend to sell the debt security, but it is probable that we will not collect all amounts due, then only the impairment due to the credit risk would be recognized in earnings and the remaining amount of the impairment would be recognized in accumulated other comprehensive loss within stockholders’ equity. Cash consists of cash deposits held in global financial institutions. Prior to Spin-Off, our domestic cash receipts had been transferred to Expedia, which had historically funded our domestic disbursement accounts as required. Transfers of cash between TripAdvisor and Expedia resulted in increases or decreases to our net related-party receivable. In connection with the Spin-Off any subsequent cash transfers related to business operations between TripAdvisor and Expedia ceased. Fair Value Measurements We apply fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. We measure assets and liabilities at fair value based on the expected exit price, which is the amount that would be received on the sale of an asset or amount paid to transfer a liability, as the case may be, in an orderly transaction between market participants in the principal or most advantageous market in which we would transact. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability at the measurement date. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs, used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value: Level 1—Valuations are based on quoted prices for identical assets and liabilities in active markets. Level 2—Valuations are based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3—Valuations are based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. Derivative Financial Instruments Our goal in managing our foreign exchange risk is to reduce, to the extent practicable, our potential exposure to the changes that exchange rates might have on our earnings, cash flows and financial position. We account for our derivative instruments as either assets or liabilities and carry them at fair value. For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income (loss) in shareholders’ equity and reclassified into income in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument, if any, is recognized in current income. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions. For options designated as cash flow hedges, changes in the time value are excluded from the assessment of hedge effectiveness and are recognized in income. For derivative instruments that hedge the exposure to changes in the fair value of an asset or a liability and that are designated as fair value hedges, both the net gain or loss on the derivative instrument as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in earnings in the current period. The net gain or loss on the effective portion of a derivative instrument that is designated as an economic hedge of the foreign currency translation exposure of the net investment in a foreign operation is reported in the same manner as a foreign currency translation adjustment. For forward exchange contracts designated as net investment hedges, we exclude changes in fair value relating to changes in the forward carrying component from its definition of effectiveness. Accordingly, any gains or losses related to this component are recognized in current income. We have not entered into any cash flow, fair value or net investment hedges to date as of December 31, 2012. Derivatives that do not qualify as hedges must be adjusted to fair value through current income. In certain circumstances, we enter into foreign currency forward exchange contracts (“forward contracts”) to reduce the effects of fluctuating foreign currency exchange rates on our cash flows denominated in foreign currencies. Our derivative instruments or forward contracts that were entered into and are not designated as hedges as of December 31, 2012 are disclosed below in “Note 5—Financial Instruments” in the notes to the consolidated and combined financial statements. Monetary assets and liabilities denominated in a currency other than the functional currency of a given subsidiary are remeasured at spot rates in effect on the balance sheet date with the effects of changes in spot rates reported in Other, net on our consolidated and combined statement of operations. Accordingly, fair value changes in the forward contracts help mitigate the changes in the value of the remeasured assets and liabilities attributable to changes in foreign currency exchange rates, except to the extent of the spot-forward differences. These differences are not expected to be significant due to the short-term nature of the contracts, which typically have average maturities at inception of less than one year. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are generally due within 30 days and are recorded net of an allowance for doubtful accounts. We consider accounts outstanding longer than the contractual payment terms as past due. We determine our allowance by considering a number of factors, including the length of time trade accounts receivable are past due, previous loss history, a specific customer’s ability to pay its obligations to us, and the condition of the general economy and industry as a whole. Property and Equipment, Including Website and Software Development Costs We record property and equipment at cost, net of accumulated depreciation. We capitalize certain costs incurred during the application development stage related to the development of websites and internal use software. Capitalized costs include internal and external costs, if direct and incremental, and deemed by management to be significant. We expense costs related to the planning and post-implementation phases of software and website development as these costs are incurred. Maintenance and enhancement costs (including those costs in the post-implementation stages) are typically expensed as incurred, unless such costs relate to substantial upgrades and enhancements to the website or software resulting in added functionality, in which case the costs are capitalized. We compute depreciation using the straight-line method over the estimated useful lives of the assets, which is three to five years for computer equipment, capitalized software and website development and furniture and other equipment. We depreciate leasehold improvement using the straight-line method, over the shorter of the estimated useful life of the improvement or the remaining term of the lease. Leases We lease facilities in several countries around the world and certain equipment under non-cancelable lease agreements. The terms of some of the lease agreements provide for rental payments on a graduated basis. Rent expense is recognized on a straight-line basis over the lease period and accrued as rent expense incurred but not paid. Recoverability of Goodwill and Indefinite-Lived Intangible Assets Goodwill: We account for acquired businesses using the purchase method of accounting which requires that the assets acquired and liabilities assumed be recorded at the date of acquisition at their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. We assess goodwill, which is not amortized, for impairment annually as of October 1, or more frequently, if events and circumstances indicate impairment may have occurred. We test goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment). We have one reportable segment. The segment is determined based on how our chief operating decision maker manages our business, makes operating decisions and evaluates operating performance. In the evaluation of goodwill for impairment, we first perform a qualitative assessment to determine whether it is more likely than not (i.e., a likelihood of more than 50%) that the fair value of the reporting unit is less than the carrying amount. If we determine that it is not more likely than not that the fair value of the goodwill is less than its carrying amount, no further testing is necessary. If, however, we determine that it is more likely than not that the fair value of the goodwill is less than its carrying amount, we then perform a quantitative assessment and compare the fair value of the reporting unit to the carrying value. If the carrying value of a reporting unit exceeds its fair value, the goodwill of that reporting unit is potentially impaired and we proceed to step two of the impairment analysis. In step two of the analysis, we will record an impairment loss equal to the excess of the carrying value of the reporting unit’s goodwill over its implied fair value should such a circumstance arise. Indefinite-Lived Intangible Assets: Intangible assets that have indefinite lives are not amortized and are tested for impairment annually on October 1, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Similar to the qualitative assessment for goodwill, we may assess qualitative factors to determine if it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. If we determine that it is not more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount, no further testing is necessary. If, however, we determine that it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount, we compare the fair value of the indefinite-lived asset with its carrying amount. If the carrying value of an individual indefinite-lived intangible asset exceeds its fair value, the individual asset is written down by an amount equal to such excess. The assessment of qualitative factors is optional and at our discretion. We may bypass the qualitative assessment for any indefinite-lived intangible asset in any period and resume performing the qualitative assessment in any subsequent period. As part of our qualitative assessment for our 2012 impairment analysis , the factors that we considered for our goodwill and indefinite-lived intangible assets included, but were not limited to: (a) changes in macroeconomic conditions in the overall economy and the specific markets in which we operate, (b) our ability to access capital, (c) changes in the online travel industry, (d) changes in the level of competition, (e) comparison of our current financial performance to historical and budgeted results, (f) changes in excess market capitalization over book value based on our current common stock price and latest consolidated balance sheet, and (g) comparison of the excess of the fair value of our of trade names and trademarks to the carrying value of those same assets, using the results of our most recent quantitative assessment. After considering these factors and the impact that changes in such factors would have on the inputs used in our previous quantitative assessment, we determined for our goodwill and indefinite-lived intangible assets that it was more likely than not that these assets were not impaired. Since the annual impairment tests in October 2012, there have been no events or changes in circumstances to indicate any potential impairment to goodwill or our indefinite lived intangible assets. In the event that future circumstances indicate that any portion of our goodwill or our indefinite-lived intangibles is impaired, an impairment charge would be recorded. Recoverability of Intangible Assets with Definite Lives and Other Long-Lived Assets Intangible assets with definite lives and other long-lived assets are carried at cost and are amortized on a straight-line basis over their estimated useful lives of two to ten years. We review the carrying value of long-lived assets or asset groups, including property and equipment, to be used in operations whenever events or changes in circumstances indicate that the carrying amount of the assets might not be recoverable. Factors that would necessitate an impairment assessment include a significant adverse change in the extent or manner in which an asset is used, a significant adverse change in legal factors or the business climate that could affect the value of the asset, or a significant decline in the observable market value of an asset, among others. If such facts indicate a potential impairment, we assess the recoverability of the asset by determining if the carrying value of the asset exceeds the sum of the projected undiscounted cash flows expected to result from the use and eventual disposition of the asset over the remaining economic life of the asset. If the recoverability test indicates that the carrying value of the asset is not recoverable, we will estimate the fair value of the asset using appropriate valuation methodologies which would typically include an estimate of discounted cash flows. Any impairment would be measured as the difference between the asset’s carrying amount and its estimated fair value. We have not identified any circumstances that would warrant an impairment assessment as of December 31, 2012. Income Taxes We compute and account for our income taxes on a stand-alone basis. We record income taxes under the liability method. Deferred tax assets and liabilities reflect our estimation of the future tax consequences of temporary differences between the carrying amounts of assets and liabilities for book and tax purposes. We determine deferred income taxes based on the differences in accounting methods and timing between financial statement and income tax reporting. Accordingly, we determine the deferred tax asset or liability for each temporary difference based on the enacted tax rates expected to be in effect when we realize the underlying items of income and expense. We consider all relevant factors when assessing the likelihood of future realization of our deferred tax assets, including our recent earnings experience by jurisdiction, expectations of future taxable income, and the carryforward periods available to us for tax reporting purposes, as well as assessing available tax planning strategies. We may establish a valuation allowance to reduce deferred tax assets to the amount we believe is more likely than not to be realized. Due to inherent complexities arising from the nature of our businesses, future changes in income tax law, tax sharing agreements or variances between our actual and anticipated operating results, we make certain judgments and estimates. Therefore, actual income taxes could materially vary from these estimates. We recognize in our consolidated and combined financial statements the impact of a tax position, if that position is more likely than not to be sustained upon an examination, based on the technical merits of the position. Foreign Currency Translation and Transaction Gains and Losses Certain of our operations outside of the United States use the related local currency as their functional currency. We translate revenue and expense at average rates of exchange during the period. We translate assets and liabilities at the rates of exchange as of the consolidated balance sheet dates and include foreign currency translation gains and losses as a component of accumulated other comprehensive income. Due to the nature of our operations and our corporate structure, we also have subsidiaries that have transactions in foreign currencies other than their functional currency. We record transaction gains and losses in our consolidated and combined statements of operations related to the recurring re-measurement and settlement of such transactions. Accordingly, we have recorded foreign exchange losses of $3.2 million, 1.0 million and $1.6 million for the years ended December 31, 2012, 2011 and 2010, respectively, in Other, net. Advertising Expense We incur advertising expense consisting of traffic generation costs from search engines and Internet portals, other online and offline advertising expense, promotions and public relations to promote our brands. We expense the costs associated with advertisements in the period in which the advertisement takes place. For the years ended December 31, 2012, 2011 and 2010, our advertising expense was $175.0 million, $135.6 million, and $86.3 million, respectively. Stock-Based Compensation TripAdvisor Equity Grants Assumed at Spin-Off All stock-based compensation included in our consolidated and combined financial statements prior to the Spin-Off relates to Expedia common stock options and restricted stock units (“RSUs”) held by TripAdvisor employees prior to the Spin-Off. The following methods were used to measure the fair value of these awards and we will continue to amortize the fair value thereof as follows for all pre-Spin-Off equity grants: Stock Options. The value of stock options issued or modified, including unvested options assumed in acquisitions, on the grant date (or modification or acquisition dates, if applicable) were measured at fair value, using the Black-Scholes option valuation model. The Black-Scholes model incorporates various assumptions including expected volatility, expected term, dividend yield and risk-free interest rates. The expected volatility was based on historical volatility of Expedia’s common stock and other relevant factors. The expected term assumptions were based on historical experience and on the terms and conditions of the stock awards granted to employees. We will continue to amortize the fair value, net of estimated forfeitures, over the remaining vesting term on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date. The majority of these stock options vest over four years. Restricted Stock Units. RSUs are stock awards granted to employees entitling the holder to shares of common stock as the award vests, typically over a five-year period. RSUs were measured at fair value based on the number of shares granted and the quoted price of Expedia’s common stock at the date of grant. We will continue to amortize the fair value of these awards, net of estimated forfeitures, as stock-based compensation expense over the vesting term on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date. TripAdvisor Equity Grants Awards Issued Subsequent to the Spin-Off We adopted the TripAdvisor, Inc. 2011 Stock and Annual Incentive Plan, or the 2011 Incentive Plan, as of December 21, 2011, under which we may grant restricted stock, restricted stock awards, RSUs, stock options and other stock-based awards to our directors, officers, employees and consultants. Refer to “Note 4—Stock Based Awards and Other Equity Instruments” below for further information on the 2011 Incentive Plan and our stock based award activity. Stock Options. The exercise price for all stock options granted by us to date has been equal to the market price of the underlying shares of common stock at the date of grant. In this regard, when making stock option awards, our practice is to determine the applicable grant date and to specify that the exercise price shall be the closing price of our common stock on the date of grant. Stock options granted during the year ended December 31, 2012 had a term of ten years from the date of grant and generally vest over a four-year period. The estimated fair value of the options granted under the 2011 Incentive Plan to date, have been 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, 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 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. We amortize the fair value, net of estimated forfeitures, as stock-based compensation expense over the vesting term on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date. Restricted Stock Units. RSUs are stock awards that are granted to employees entitling the holder to shares of our common stock as the award vests. RSUs are measured at fair value based on the number of shares granted and the quoted price of our common stock at the date of grant. We amortize the fair value, net of estimated forfeitures, as stock-based compensation expense over the vesting term on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date. Performance-based stock options and RSUs vest upon achievement of certain company-based performance conditions and a requisite service period. On the date of grant, the fair value of performance-based awards is determined based on the fair value, which is calculated using the same method as our service based stock options and RSUs described above. We then assess whether it is probable that the performance targets would be achieved. If assessed as probable, compensation expense will be recorded for these awards over the estimated performance period on a straight-line basis. At each reporting period, we will reassess the probability of achieving the performance targets and the performance period required to meet those targets. The estimation of whether the performance targets will be achieved and of the performance period required to achieve the targets requires judgment, and to the extent actual results or updated estimates differ from our current estimates, the cumulative effect on current and prior periods of those changes will be recorded in the period estimates are revised, or the change in estimate will be applied prospectively depending on whether the change affects the estimate of total compensation cost to be recognized or merely affects the period over which compensation cost is to be recognized. The ultimate number of shares issued and the related compensation expense recognized will be based on a comparison of the final performance metrics to the specified targets. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive these awards, and subsequent events are not indicative of the reasonableness of our original estimates of fair value. We have considered many factors when estimating expected forfeitures, including our historical attrition rates, the employee class and historical experience. The estimate of stock awards that will ultimately be forfeited requires significant judgment and, to the extent that actual results or updated estimates differ from our current estimates, such amounts will be recorded as a cumulative adjustment in the period such estimates are revised. Certain Risks and Concentrations Our business is subject to certain risks and concentrations including dependence on relationships with our customers. We are highly dependent on our advertising and media relationship with Expedia, (see “Note 16—Related Party Transactions”), which accounted for approximately 27%, 33% and 35% of our total revenue in 2012, 2011 and 2010, respectively. In addition, another customer accounted for approximately 21%, 16% and 11% of our revenue in 2012, 2011 and 2010, respectively. As of December 31, 2012 and 2011, there were no customers that accounted for 10% or more of our trade receivables. Contingent Liabilities Periodically, we review the status of all significant outstanding matters to assess any potential financial exposure. When (i) it is probable that an asset has been impaired or a liability has been incurred and (ii) the amount of the loss can be reasonably estimated, we record the estimated loss in our consolidated and combined statements of operations. We provide disclosure in the notes to the consolidated and combined financial statements for loss contingencies that do not meet both these conditions if there is a reasonable possibility that a loss may have been incurred that would be material to the financial statements. Significant judgment is required to determine the probability that a liability has been incurred and whether such liability is reasonably estimable. We base accruals made on the best information available at the time which can be highly subjective. The final outcome of these matters could vary significantly from the amounts included in the accompanying consolidated and combined financial statements. Comprehensive Loss Comprehensive loss consists of net income (loss), cumulative foreign currency translation adjustments, and unrealized gains and losses on available-for-sale securities, net of tax. Earnings per Share (EPS) As discussed above in “Note 1—Organization and Basis of Presentation”, in connection with the Spin-Off a one-for-two reverse stock split of outstanding Expedia capital stock occurred immediately prior to the Spin-Off, which resulted in 120,661,020 shares of common stock and 12,799,999 shares of Class B common stock outstanding immediately following the Spin-Off. Basic Earnings Per Share For the year ending ended December 31, 2012, we computed basic earnings per share using the number of shares of common stock and Class B common stock outstanding as of December 31, 2011 plus the weighted average of any additional shares issued and outstanding during the year ended December 31, 2012. For the year ended December 31, 2011, we computed basic earnings per share using the number of shares of common stock and Class B common stock outstanding immediately following the Spin-Off, as if such shares were outstanding for the entire period prior to the Spin-Off, plus the weighted average of any additional shares issued and outstanding following the Spin-Off date through December 31, 2011. For the year ended December 31, 2010, we computed basic earnings per share using the number of shares of common stock and Class B common stock outstanding immediately following the Spin-Off, as if such shares were outstanding for the entire period. Diluted Earnings Per Share For the year ended December 31, 2012, we computed diluted earnings per share using (i) the number of shares of common stock and Class B common stock outstanding at December 31, 2011, (ii) the weighted average of any additional shares issued and outstanding for the year ended December 31, 2012, and (iii) if dilutive, the incremental weighted average common stock that we would issue upon the assumed exercise of common equivalent shares related to stock options, stock warrants and the vesting of restricted stock units using the treasury stock method during the year ended December 31, 2012, and (iv) 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. For the year ended December 31, 2011, we computed diluted earnings per share using (i) the number of shares of common stock and Class B common stock outstanding immediately following the Spin-Off, (ii) the weighted average of any additional shares issued and outstanding shares outstanding following the Spin-Off date through December 31, 2011, and (iii) if dilutive, the incremental weighted average common stock that we would issue upon the assumed exercise of common equivalent shares related to stock options, stock warrants and the vesting of restricted stock units using the treasury stock method during the year ended December 31, 2011, and (iv) if dilutive, performance based awards based on the number of shares that would be issuable as of the end of the reporting period assuming the end of the reporting period was also the end of the contingency period. We treated all outstanding equity awards assumed at Spin-Off as if they were granted as of the Spin-Off and we included them in our diluted earnings per share calculation for the year ended December 31, 2011, based on the number of days they were outstanding. For the year ended December 31, 2010, we computed diluted earnings per share using (i) the number of shares of common stock and Class B common stock outstanding immediately following the Spin-Off, as no TripAdvisor equity awards were outstanding prior to the Spin-Off. 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):

RSUs |  |  | 161 |  |  |  | 240 |  |  |  | — |
Stock warrants |  |  | 511 |  |  |  | — |  |  |  | — |
Weighted average shares used to compute Diluted EPS |  |  | 141,341 |  |  |  | 134,865 |  |  |  | 133,461 |

The following potential common shares related to stock options, stock warrants and RSUs were excluded from the calculation of diluted net income per share because their effect would have been anti-dilutive for the periods presented (in thousands):
|  | During the Year Ended December 31, |
|  | 2012(1)(2) |  |  | 2011(2) |  |  | 2010 |
Stock options |  |  | 3,944 |  |  |  | 2,261 |  |  |  | — |
RSUs |  |  | 21 |  |  |  | 80 |  |  |  | — |
Warrants |  |  | — |  |  |  | 8,047 |  |  |  | — |
Total |  |  | 3,965 |  |  |  | 10,388 |  |  |  | — |
(1) | These totals do not include performance based options representing the right to acquire 110,000 shares of common stock, respectively, for which all targets required to trigger vesting have not been achieved; therefore, such awards were excluded from the calculation of weighted average shares used to compute diluted earnings per share for those reporting periods.
(2) | These totals do not include performance based RSUs representing the right to acquire 200,000 and 400,000 shares of common stock at December 31, 2012 and 2011, respectively, for which all targets required to trigger vesting have not been achieved; therefore, such awards were excluded from the calculation of weighted average shares used to compute diluted earnings per share for those reporting periods.
The earnings per share amounts are the same for common stock and Class B common stock because the holders of each class are legally entitled to equal per share distributions whether through dividends or in liquidation. Recently Adopted Accounting Pronouncements Testing Indefinite-lived Intangibles for Impairment In July 2012, the FASB issued ASU 2012-02, which amends ASC Topic 350, “Intangibles—Goodwill and Other.” The guidance amends the impairment test for indefinite lived intangible assets other than goodwill by allowing companies to first assess qualitative factors to determine if it is more likely than not that an indefinite lived intangible asset is impaired and whether it is necessary to perform the impairment test of comparing the carrying amount with the recoverable amount of the indefinite lived intangible asset. This guidance is effective for interim and annual periods beginning after September 15, 2012, however, we have decided to early adopt and make it effective for our 2012 impairment review. Accordingly, we have adopted the presentation requirements of ASU 2012-02 during the fourth quarter of 2012. The adoption of ASU 2012-02 did not have a material impact on our consolidated and combined financial statements. New Accounting Pronouncements Not Yet Adopted Disclosure about Offsetting Assets and Liabilities In December 2011, the FASB issued ASU 2011-11, which amends ASC Subtopic 210-20, “Offsetting.” The guidance requires enhanced disclosures with improved information about financial instruments and derivative instruments that are either (i) offset in accordance with current guidance or (ii) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in accordance with current guidance. This guidance is effective for interim and annual periods beginning after January 1, 2013. The guidance is limited to the form and content of disclosures, and we do not anticipate that the adoption of this guidance will have an impact on our consolidated and combined financial statements.
