Business Description and Basis of Presentation

NOTE 1: BUSINESS DESCRIPTION AND BASIS OF PRESENTATION

We refer to TripAdvisor, Inc. and our subsidiaries as “TripAdvisor”, “the Company”, “us”, “we” and “our” in these notes to the unaudited condensed consolidated financial statements.

Description of Business

TripAdvisor is an online travel company and our mission is to help people around the world plan, book and experience the perfect trip. We seek to achieve our mission by providing consumers and travel partners a global platform of rich content, price comparison tools and online reservation and related services for destinations, accommodations, travel activities and experiences, and restaurants.

TripAdvisor, Inc., by and through its subsidiaries, owns and operates a portfolio of leading online travel brands. Our flagship brand is TripAdvisor. TripAdvisor-branded websites include tripadvisor.com in the United States and localized versions of the website in 48 markets and 28 languages worldwide. TripAdvisor features approximately 830 million reviews and opinions on approximately 8.6 million places to stay, places to eat and things to do – including 1.4 million hotels, inns, B&Bs and specialty lodging, 885,000 rental properties, 5.1 million restaurants and 1.2 million travel activities and experiences worldwide. We also enable consumers to compare prices and book a number of these travel experiences on either a TripAdvisor website or mobile application (“mobile app”), or on the website or mobile app of one of our travel partners. In addition to the flagship TripAdvisor brand, we manage and operate the following other travel media brands: www.airfarewatchdog.com, www.bokun.io, www.bookingbuddy.com, www.cruisecritic.com, www.familyvacationcritic.com, www.flipkey.com, www.thefork.com (including www.lafourchette.com, www.eltenedor.com, and www.restorando.com), www.holidaylettings.co.uk, www.holidaywatchdog.com, www.housetrip.com, www.jetsetter.com, www.niumba.com, www.onetime.com, www.oyster.com, www.seatguru.com, www.smartertravel.com, www.tingo.com, www.vacationhomerentals.com, and www.viator.com.

During the first quarter of 2019, as part of our continuous review of the business, we evaluated our operations and realigned the reportable segment information which our chief operating decision maker, or CODM, regularly assesses to evaluate performance for operating decision-making purposes, including evaluation and allocation of resources. The CODM for the Company is our Chief Executive Officer. The revised segment reporting structure includes the following reportable segments: (1) Hotels, Media & Platform; and (2) Experiences & Dining. For further information on our segments, including the change in segments, and principal revenue streams within these segments refer to “Note 3: Revenue Recognition” and “Note 15: Segment Information,” in these notes to our unaudited condensed consolidated financial statements. All prior period segment disclosure information has been reclassified to conform to the current reporting structure in this Form 10-Q. These reclassifications had no effect on our unaudited condensed consolidated financial statements in any period.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements present our results of operations, financial position and cash flows on a consolidated basis. The unaudited condensed consolidated financial statements include TripAdvisor, our wholly-owned subsidiaries, and entities we control, or in which we have a variable interest and are the primary beneficiary of expected cash profits or losses. All inter-company accounts and transactions have been eliminated in consolidation. One of our subsidiaries that operates in China has 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 these 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 activity of these affiliates. Our variable interest entities’ financials were not material for all periods presented.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and include all normal and recurring adjustments that management of the Company considers necessary for a fair presentation of its financial position and operating results. We prepared the unaudited condensed consolidated financial statements following the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, we condensed or omitted certain footnotes or other financial information that are normally required by GAAP for annual financial statements. Additionally, certain prior period amounts have been reclassified for comparability with the current period presentation. Our interim unaudited condensed consolidated financial statements are not necessarily indicative of results that may be expected for any other interim period or for the full year. These interim unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2018, previously filed with the SEC. The

unaudited condensed consolidated balance sheet as of December 31, 2018 included herein was derived from the audited consolidated financial statements as of that date, but does not include all disclosures including notes required by GAAP.

Accounting Estimates

We use estimates and assumptions in the preparation of our unaudited condensed 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 unaudited condensed 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 unaudited condensed consolidated financial statements include: (i) recognition and recoverability of goodwill, definite-lived intangibles and other long-lived assets; and (ii) accounting for income taxes.

Seasonality

Global travel market expenditures tend to follow a seasonal pattern. Correspondingly, advertising investments made by travel partners and, therefore, our revenue and profits, also tend to follow a seasonal pattern. Our financial performance tends to be seasonally highest in the second and third quarters of a given year, which includes the seasonal peak in consumer demand, traveler hotel and rental stays, and travel activities and experiences taken, compared to the first and fourth quarters, which represent seasonal low points. Significant shifts in our business mix or adverse economic conditions could result in future seasonal patterns that are different from historical trends.

Significant Accounting Policies

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES

New Accounting Pronouncements Not Yet Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance which require a customer in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract to follow the internal-use software guidance to determine which implementation costs to capitalize as assets or expense as incurred. The accounting for the cost of the hosting component of the arrangement (i.e., service costs the customer pays for the cloud computing service) is not affected by this new guidance. The Company uses both internally-developed software and third-party software to operate its business. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted, including adoption in any interim period. Entities have the option to apply the guidance retrospectively or prospectively to all implementation costs incurred after the date of adoption. We plan on adopting this new guidance on January 1, 2020 on a prospective basis without adjusting the comparative periods presented. We do not expect the adoption of this new guidance will have a material impact on our consolidated financial statements and related disclosures.

In June 2016, the FASB issued new accounting guidance which replaces the existing incurred loss impairment model with an expected loss methodology on the measurement of credit losses for financial assets measured at amortized cost, which includes accounts receivable and available-for-sale debt securities. For financial assets measured at amortized cost, this new guidance requires an entity to: (1) estimate its lifetime expected credit losses upon recognition of the financial assets and establish an allowance to present the net amount expected to be collected; (2) recognize this allowance and changes in the allowance during subsequent periods through net income; and (3) consider relevant information about past events, current conditions and reasonable and supportable forecasts in assessing the lifetime expected credit losses. For available-for-sale debt securities, this new guidance made several targeted amendments to the existing other-than-temporary impairment model, including: (1) requiring disclosure of the allowance for credit losses; (2) allowing reversals of the previously recognized credit losses until the entity has the intent to sell, is more-likely-than-not required to sell the securities or the maturity of the securities; (3) limiting impairment to the difference between the amortized cost basis and fair value; and (4) not allowing entities to consider the length of time that fair value has been less than amortized cost as a factor in evaluating whether a credit loss exists. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted, including interim periods within those fiscal years beginning after December 15, 2018. Entities are required to adopt this new guidance on a modified retrospective basis with a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. We plan on adopting this new guidance on January 1, 2020. While we continue to evaluate the impact of adopting this new guidance, we currently do not expect it will have a material impact on our consolidated financial statements.

Recently Adopted Accounting Pronouncements

In February 2016, the FASB issued new guidance which revises the accounting for leases (“ASC 842”). ASC 842 requires entities that lease assets to recognize right-of-use (ROU) assets representing its right to use the underlying asset for the lease term and lease liabilities related to the rights and obligations created by those leases on the balance sheet regardless of whether they are classified as finance or operating leases, with classification affecting the pattern and presentation of expenses and cash flows on our consolidated financial statements. In addition, new disclosures are required to meet the objective of enabling users of the financial statements to better understand the amount, timing, and uncertainty of cash flows arising from leases. We adopted ASC 842 on January 1, 2019 and elected the modified retrospective transition method that allowed for a cumulative-effect adjustment in the period of adoption. Financial results for reporting periods beginning after January 1, 2019 are presented under ASC 842, while prior period amounts were not adjusted and continue to be reported under the accounting standards in effect for those periods. The Company has also updated its accounting policies to reflect the new guidance and has implemented lease accounting software to support its accounting process, financial reporting, and new financial disclosure requirements.

We elected the following practical expedients available in transition upon adoption of ASC 842 and accounting policy updates: 1) the “practical expedients package of three”, which allows us to not reassess the following as of the adoption date: a) whether any expired or existing contracts are or contain a lease; b) the lease classification for any expired or existing leases ; and c) the accounting treatment for initial direct costs for existing leases ; 2) the “short-term lease recognition exemption”, which allows entities to forego recognition of ROU assets and lease liabilities for leases with a lease term of twelve months or less and which also do not include an option to renew the lease term that the entity is reasonably certain to exercise; 3) elect by asset class as an accounting policy, to combine lease and non-lease components as a single component and subsequently account for the combined single component as the lease component; and 4) apply the portfolio approach to similar types of leases where the Company does not reasonably expect the outcome to differ materially from applying the new guidance to individual leases.

The adoption of ASC 842 did not have a material impact to both our unaudited condensed consolidated statement of operations during the three and nine months ended September 30, 2019 and unaudited condensed consolidated statement of cash flows during the nine months ended September 30, 2019. The effect on our unaudited condensed consolidated balance sheet as of January 1, 2019 from the adoption of ASC 842 is as follows:

We lease office space in a number of countries around the world under non-cancelable lease agreements. Our corporate headquarters lease (“Headquarters Lease”) is our most significant office space lease. The Company has also entered into data center and certain equipment leases, such as network equipment and other leases, which are not material to our unaudited condensed consolidated financial statements. We determine whether a contract is or contains a lease at inception of a contract. We define a lease as a contract, or part of a contract, that conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. Control over the use of the identified asset means that we have both the right to obtain substantially all of the economic benefits from the use of the asset and the right to direct the use of the asset.

Our lease contracts contain both lease and non-lease components. We account separately for the lease and non-lease components of office space leases and certain other leases, such as data center leases. We allocate the consideration in the contract to the lease and non-lease components based on each component’s relative standalone price. We determine standalone prices for the lease components based on the prices for which other lessors lease similar assets on a standalone basis. We determine standalone prices for the non-lease component based on the prices that other suppliers charge for services for similar assets on a standalone basis. If observable standalone prices are not readily available, we estimate the standalone prices based on other available observable information. However, for certain categories of equipment leases, such as network equipment and others, we account for the lease and non-lease components as a single lease component. Additionally, for certain equipment leases that have similar characteristics, we apply a portfolio approach to effectively account for operating lease ROU assets and operating lease liabilities, hence we do not expect the outcome to differ materially from applying the new guidance to individual leases.

The Company uses its estimated incremental borrowing rate as the discount rate in measuring the present value of our lease payments given the rate implicit in our leases is not typically readily determinable. Given we do not currently borrow on a collateralized basis, our incremental borrowing rate is estimated to approximate the interest rate in which the Company would expect to pay on a collateralized basis over a similar term and payments, and in economic environments where the leased asset is located. We use the portfolio approach to determine the discount rate for leases with similar characteristics or when the Company is reasonably certain that doing so would not materially affect the accounting for those leases to which a single discount rate is applied.

Operating Leases

Our office space leases, exclusive of our Headquarters Lease, are operating leases, which expire at various dates with the latest maturity in June 2027. Based on the present value of remaining lease payments on the Company's existing leases, we recognized $88 million of both operating ROU assets and operating lease liabilities, respectively, on our unaudited condensed consolidated balance sheet upon adoption of ASC 842, as of January 1, 2019. These operating ROU assets were then reduced by a net deferred rent balance of $13 million as of January 1, 2019, which primarily consisted of existing deferred and prepaid rent balances.

Operating lease ROU assets and liabilities commencing after January 1, 2019 are recognized at lease commencement date, or the date the lessor makes the leased asset available for use, based on the present value of lease payments over the lease term using the Company’s estimated incremental borrowing rate. ROU assets related to operating leases comprise the initial lease liability, and are then adjusted for any prepaid or deferred rent payments, unamortized initial direct costs, and lease incentives received. Amortization expense for operating lease ROU assets and interest accretion on operating lease liabilities are recognized as a single operating lease cost in our consolidated statement of operations, which results effectively in recognition of rent expense on a straight-line basis over the lease period. The carrying amount of operating lease liabilities are (1) accreted to reflect interest using the incremental borrowing rate if the rate implicit in the lease is not readily determinable; and (2) reduced to reflect lease payments made during the period. We present the combination of both the amortization of operating lease ROU assets and the change in the operating lease liabilities in the same line item in the adjustments to reconcile net income to net cash provided by operating activities in our unaudited condensed consolidated statement of cash flows. Lease incentives are recognized as reductions of rental expense on a straight-line basis over the term of the lease. Certain of our operating leases include options to extend the lease terms for up to 6 years and/or terminate the leases within 1 year, which we include in our lease term if we are reasonably certain to exercise these options. Payments under our operating leases are primarily fixed, however, certain of our operating lease agreements include rental payments which are adjusted periodically for inflation. We recognize these costs as variable lease costs on our unaudited condensed consolidated statement of operations, which were not material during the three and nine months ended September 30, 2019 and 2018. In addition, our short-term lease costs were not material in any period. As of September 30, 2019, we had operating lease ROU assets of $76 million on our unaudited condensed consolidated balance sheet.

Finance Lease

In June 2013, we entered into our Headquarters Lease. Pursuant to the Headquarters Lease, the landlord built an approximately 280,000 square foot rental building in Needham, Massachusetts (the “Premises”), and leased the Premises to the Company as our new corporate headquarters for an initial term of 15 years and 7 months or through December 2030. The Company also has an option to extend the term of the Headquarters Lease for two consecutive terms of five years each. The Company was deemed to be the owner of the Premises for accounting purposes only during the construction period under legacy GAAP lease accounting rules, or ASC 840. Accordingly, the Company recorded project construction costs during the construction period incurred by the landlord as a construction-in-progress asset and a related construction financing obligation on our consolidated balance sheet. The amounts that the Company incurred for normal tenant improvements and structural improvements had also been recorded to the construction-in-progress asset. Upon completion of construction at the end of the second quarter of 2015, we evaluated the construction-in-progress asset and construction financing obligation for de-recognition under the criteria for “sale-leaseback” treatment under ASC 840. We concluded that it did not meet the provisions for sale-leaseback accounting. Therefore, the Headquarters Lease was accounted for as a

financing obligation through December 31, 2018, in which we depreciated the building asset over its estimated useful life and incurred interest expense related to the financing obligation, imputed using the effective interest rate method.

Upon the adoption of ASC 842 on January 1, 2019, we derecognized the previous asset and liability recorded for the Headquarters Lease described above, with the exception of a net asset of $26 million, primarily related to structural improvements paid by the Company, net of tenant incentives and accumulated amortization, which is classified as prepaid rent under the new guidance. The Company then assessed the lease classification of our Headquarters Lease and concluded it should be classified and accounted for as a finance lease upon adoption on January 1, 2019. Accordingly, on January 1, 2019, we recognized a finance lease ROU asset and a finance lease liability of $114 million and $88 million, respectively, on our unaudited condensed consolidated balance sheet. The difference between the finance lease ROU asset and finance lease liability represents the aforementioned $26 million of net prepaid rent, and is being amortized straight-line over the remaining lease term. As of September 30, 2019, the ROU asset related to our Headquarters Lease was $107 million, net of accumulated amortization of $7 million, and is included in the property and equipment, net on our unaudited condensed consolidated balance sheet.

Finance lease ROU assets and finance lease liabilities commencing after January 1, 2019 are recognized similar to an operating lease, at the lease commencement date or the date the lessor makes the leased asset available for use. Finance lease ROU assets are generally amortized on a straight-line basis over the lease term, and the carrying amount of the finance lease liabilities are (1) accreted to reflect interest using the incremental borrowing rate if the rate implicit in the lease is not readily determinable, and (2) reduced to reflect lease payments made during the period. Amortization expense for finance lease ROU assets and interest accretion on finance lease liabilities are recorded to depreciation and interest expense, respectively, in our consolidated statement of operations.

We did not update any financial information or provide any disclosures required under the new guidance for the three and nine months ended September 30, 2018, respectively, or as of December 31, 2018. The disclosures provided below for the three and nine months ended September 30, 2018, respectively, or as of December 31, 2018 are based on the disclosure requirements under ASC 840.

Revenue Recognition

Sep. 30, 2019

Revenue From Contract With Customer [Abstract]

Revenue Recognition

NOTE 3: REVENUE RECOGNITION

We generate all of our revenue from contracts with customers. We recognize revenue when we satisfy a performance obligation by transferring control of the promised services to a customer in an amount that reflects the consideration that we expect to receive in exchange for those services. When we act as an agent in the transaction under Revenue from Contracts with Customers (“ASC 606”), we recognize revenue for only our commission on the arrangement. We determine revenue recognition through the following steps:

(1)	Identification of the contract, or contracts, with a customer

(2)	Identification of the performance obligations in the contract

(3)	Determination of the transaction price

(4)	Allocation of the transaction price to the performance obligations in the contract

(5)	Recognition of revenue when, or as, we satisfy a performance obligation

At contract inception, we assess the services promised in our contracts with customers and identify a performance obligation for each promise to transfer to the customer a service (or bundle of services) that is distinct. To identify the performance obligations, we consider all of the services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. We have provided qualitative information about our performance obligations for our principal revenue streams discussed below. There was no significant revenue recognized in the three and nine months ended September 30, 2019 related to performance obligations satisfied in prior periods. We have applied a practical expedient and do not disclose the value of unsatisfied performance obligations that have an original expected duration of less than one year, and we do not have any material unsatisfied performance obligations over one year. The value related to our remaining or partially satisfied performance obligations relates to subscription services that are satisfied over time or services that are recognized at a point in time, but not yet achieved. Our timing of services, invoicing and payments are discussed in more detail below and do not include a significant financing component. Our customer invoices are generally due 30 days from the time of invoicing. The application of our revenue recognition policies and a description of our principal activities, organized by reported segment, from which we generate our revenue, are presented below.

Hotels, Media & Platform Segment

TripAdvisor-branded Hotels Revenue. Our largest source of Hotels, Media & Platform segment revenue is generated from click-based advertising on TripAdvisor-branded websites, which is primarily comprised of contextually-relevant booking links to our travel partners’ websites. Our click-based travel partners are predominantly online travel agencies, or OTAs, and direct suppliers in

the hotel category. Click-based advertising is generally priced on a cost-per-click, or “CPC”, basis, with payments from travel partners determined by the number of travelers who click on a link multiplied by the CPC rate for each specific click. CPC rates that our travel partners pay are determined in a dynamic, competitive auction process, also known as our hotel metasearch auction, as travel partner CPC bids for rates and availability listed on our site are submitted. When a CPC bid is submitted, the partner agrees to pay us the bid amount each time a traveler clicks on the link to that partner’s website. Bids can be submitted periodically – as often as daily– on a property-by-property basis. We record click-based advertising revenue as the click occurs and traveler leads are sent to the travel partner websites as our performance obligation is fulfilled at that time. Click-based revenue is generally billed to our travel partners on a monthly basis consistent with the timing of the service. We also generate transaction revenue from our hotel instant booking feature, which enables hotel shoppers to book directly with a travel partner, with the latter serving as the merchant of record for the transaction, without leaving our website. We earn a commission from our travel partners for each traveler that completes a hotel reservation on our website based on a pre-determined commission rate. Our hotel instant booking revenue includes (i) arrangements where commissions are billable on all instant booking hotel reservations; and (ii) arrangements where the commissions are billable only upon the completion of each traveler’s stay resulting from the reservation. The travel partners provide the service to the travelers and we act as an agent under ASC 606. Our performance obligation in both arrangements is complete at the time of the booking and the commission earned is recognized upon booking, as we have no post-booking service obligations. The amount of revenue recognized for commissions that are billable contingent upon a traveler stay requires an estimate of the impact of cancellations using historical cancellation rates. Contract assets are recognized at the time of booking for commissions that are billable at the time of stay.

In addition, we offer subscription-based advertising to hoteliers, owners of B&Bs and other specialty lodging properties. Our performance obligation is generally to enable subscribers to advertise their businesses on our website, as well as manage and promote their website URL, email address, phone number, special offers and other information related to their business. Subscription-based advertising services are predominantly sold for a flat fee for a contracted period of time of one year or less and revenue is recognized on a straight-line basis over the period of the subscription service as efforts are expended evenly throughout the contract period. Subscription-based advertising services are generally billed at the inception of the service. When prepayments are received, we recognize deferred revenue for the amount of prepayment in excess of revenue recognized until the performance obligation is satisfied.

We also offer travel partners the opportunity to advertise and promote their business through hotel sponsored placements on our website. This service is generally priced on a CPC basis, with payments from travel partners determined by the number of travelers who click on the sponsored link multiplied by the CPC rate for each specific click. CPC rates that our travel partners pay are based on a pre-determined rate. We record click-based advertising revenue as the click occurs and traveler leads are sent to the travel partner as our performance obligation is fulfilled at that time. Click-based revenue is generally billed to our travel partners on a monthly basis consistent with the timing of the service.

TripAdvisor-branded Display and Platform Revenue. Travel partners can promote their brands through display-based advertising placements on our websites across all of our segments and business units. Our display-based advertising clients are predominantly direct suppliers of hotels, airlines and cruises, as well as destination marketing organizations. We also sell display-based advertising to OTAs and other travel related businesses, as well as advertisers from non-travel categories. Display-based advertising is sold predominantly on a cost per thousand impressions, or CPM, basis. The performance obligation in our display-based advertising arrangements is to display a number of advertising impressions on our websites and we recognize revenue for impressions as they are delivered. Services are generally billed monthly. We have applied the practical expedient to measure progress toward completion, as we have the right to invoice the customer in an amount that directly corresponds with the value to the customer of our performance to date, which is measured based on impressions delivered.

Experiences & Dining Segment

We provide information and services for consumers to research, book and experience activities and attractions in popular travel destinations both through Viator, our dedicated Experiences offering, and on our TripAdvisor website and mobile apps. We also power travel activities and experiences booking capabilities to consumers on affiliate partner websites, including some of the world’s top airlines, hotel chains, and online and offline travel agencies. We work with local tour or travel activities/experiences operators (“the supplier”) to provide consumers the ability to book tours, activities and experiences (“the activity”) in popular destinations worldwide. We generate commissions for each booking transaction we facilitate through our online reservation system. We provide post-booking service to the customer until the time of the activity, which is the completion of the performance obligation. Revenue is recognized at the time that the activity occurs. We do not control the activity before the supplier provides it to our customer and therefore act as agent for nearly all of these transactions under ASC 606. We generally collect payment from the customer at the time of booking that includes both our commission revenue and the amount due to the supplier. Our commission revenue is recorded as deferred revenue until the activity occurs and revenue is recognized, and the amount due to the supplier is recorded as deferred merchant payables on our consolidated balance sheet until completion of the activity and payment is made to the supplier. To a lesser extent, we earn commissions from affiliate partners, or third-party merchant partners who display and promote on their websites the

supplier activities available on our platform to generate bookings. In these transactions, where we are not the merchant of record, we generally invoice and receive commissions directly from the third-party merchant partners. Our performance obligation is to allow the third-party merchant partners to display and promote on their website suppliers who utilize our platform and we earn a commission when consumers book and complete an activity. We do not control the service and act as an agent for these transactions under ASC 606. Our performance obligation is complete and revenue is recognized at the time of the booking, as we have no post-booking obligations. We recognize this revenue net of an estimate of the impact of cancellations using historical cancellation rates. Contract assets are recognized for commissions that are billable contingent upon completion of the activity.

We also provide information and services for consumers to research and book restaurants in popular travel destinations through our dedicated restaurant reservations offering, TheFork, and on our TripAdvisor-branded websites and mobile apps. TheFork is an online restaurant booking platform operating on a number of websites (including www.thefork.com, www.lafourchette.com, www.eltenedor.com, and www.restorando.com), with a network of restaurant partners located primarily across Europe, Australia, and South America. We primarily generate transaction fees (or per seated diner fees) that are paid by restaurants for diners seated primarily from bookings through TheFork’s online reservation system. The transaction fee is recognized as revenue after the reservation is fulfilled, or as diners are seated by our restaurant customers. We invoice restaurants monthly for transaction fees. To a lesser extent, we also generate subscription fees for subscription-based advertising to restaurants, access to certain online reservation management services and marketing analytic tools provided by TheFork and TripAdvisor. As the performance obligation is to provide restaurants with access to these services over the subscription period, subscription fee revenue is recognized over the period of the subscription service on a straight-line basis as efforts are expended evenly throughout the contract period. Subscription fees are generally billable in advance of service. When prepayments are received, we recognize deferred revenue for the amount of prepayment in excess of revenue recognized until the performance obligation is satisfied. In addition, we also offer restaurant partners the opportunity to advertise and promote their business through restaurant media advertising placements on our website. This service is generally priced on a CPC basis, with payments from restaurant partners determined by the number of users who click on the sponsored link multiplied by the CPC rate for each specific click. CPC rates that our restaurant partners pay are based on a pre-determined rate. We record click-based advertising revenue as the click occurs and diner leads are sent to the restaurant partner as our performance obligation is fulfilled at that time. Click-based revenue is generally billed to our restaurant partners on a monthly basis consistent with the timing of the service.

Other

We provide information and services for travelers to research and book vacation and short-term rental properties, including full homes, condominiums, villas, beach properties, cabins and cottages. Our Rentals offering generates revenue primarily by offering individual property owners and managers the ability to list their properties on our websites and mobile apps thereby connecting with travelers through a free-to-list, commission-based option or, to a lesser extent, by an annual subscription-based fee structure. These properties are listed on www.flipkey.com, www.holidaylettings.co.uk, www.housetrip.com, www.niumba.com, and www.vacationhomerentals.com, and on our TripAdvisor-branded websites and mobile apps. We earn commissions associated with rental transactions through our free-to-list model from both the traveler and the property owner or manager. We provide post-booking service to the travelers, property owners and managers until the time the rental commences, which is the time the performance obligation is completed. Revenue from transaction fees is recognized at the time that the rental commences. We act as an agent, under ASC 606, in the transactions as we do not control any properties before the property owner provides the accommodation to the traveler and do not have inventory risk. We generally collect from the traveler at the time of booking payment representing the amount due to the property owner or manager, as well as our commission. That portion of the payment representing our commission is recorded as deferred revenue until revenue is recognized, and that portion of the payment representing the amount due to the property owner is recorded as deferred merchant payables until payment is made to the property owner after the completion of the rental. Payments for term-based subscription fees related to online advertising services for the listing of rental properties are generally due in advance. As the performance obligation is the listing service provided to the property owner or manager over the subscription period, revenue is recognized over the period of the subscription service on a straight-line basis as efforts are expended evenly throughout the contract period. We recognize deferred revenue for the amount of prepayment in excess of revenue recognized until the performance obligation is satisfied.

In addition, Other includes revenue generated from our flights, cruise, and rental car offerings on TripAdvisor, as well as revenue from non-TripAdvisor-branded websites not otherwise described above, such as www.bookingbuddy.com, www.cruisecritic.com, www.onetime.com and www.smartertravel.com, and TripAdvisor China, which primarily includes click-based advertising and display-based advertising revenue. The performance obligations, timing of customer payments for these brands, and methods of revenue recognition are generally consistent with click-based advertising and display-based advertising revenue, as described above.

We disaggregate revenue from contracts with customers into major products/revenue sources. We have determined that disaggregating revenue into these categories achieves the disclosure objective to depict how the nature, amount, timing, and

uncertainty of revenue and cash flows are affected by economic factors. As noted in “Note 15: Segment Information”, our business consists of two reportable segments – Hotels, Media & Platform and Experiences & Dining. A reconciliation of disaggregated revenue to segment revenue is also included below.

Our revenue is recognized primarily at a point in time for all reported segments.

The following table provides information about the opening and closing balances of accounts receivable and contract assets from contracts with customers (in millions):

	September 30, 2019		December 31, 2018
Accounts receivable		212		205
Contract assets		6		7
Total	$	218	$	212

Accounts receivable are recognized when the right to consideration becomes unconditional. Contract assets are rights to consideration in exchange for services that we have transferred to a customer when that right is conditional on something other than the passage of time, such as commission payments that are contingent upon the completion of the service by the principal in the transaction. Contract liabilities generally include payments received in advance of performance under the contract, and are realized as revenue as the performance obligation to the customer is satisfied, which we present as deferred revenue on our consolidated balance sheets. As of January 1, 2019, we had $63 million recorded as deferred revenue on our unaudited condensed consolidated balance sheet, of which $10 million and $56 million was recognized into revenue, during the three and nine months ended September 30, 2019, respectively. As of January 1, 2018, we had $59 million recorded as deferred revenue on our unaudited condensed consolidated balance sheet, of which $8 million and $53 million was recognized in revenue, during the three and nine months ended September 30, 2018, respectively. The difference between the opening and closing balances of our deferred revenue primarily results from the timing differences between when we receive customer payments and the time in which we satisfy our performance obligations. The difference between the opening and closing balances of our contract assets primarily results from the timing difference between when we satisfy our performance obligations and the time when the principal completes the service in the transaction. There were no significant changes in contract assets or deferred revenue during the nine months ended September 30, 2019 and 2018 related to business combinations, impairments, cumulative catch-ups or other material adjustments.

Earnings Per Share [Abstract]

Earnings Per Share

NOTE 4: EARNINGS PER SHARE

Basic Earnings Per Share Attributable to Common Stockholders

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

Diluted Earnings Per Share Attributable to Common Stockholders

Diluted earnings per share, or Diluted EPS, includes the potential dilution of common equivalent shares outstanding that could occur from stock-based awards and other stock-based commitments using the treasury stock method. We compute Diluted EPS by dividing net income (loss) by the sum of the weighted average number of common and common equivalent shares outstanding during the period. We computed the weighted average number of common and common equivalent shares outstanding during the period using the sum of (i) the number of shares of common stock and Class B common stock used in the Basic EPS calculation as indicated

above; and (ii) if dilutive, the incremental weighted average common stock that we would issue upon the assumed exercise of outstanding common equivalent shares, primarily related to stock options and the vesting of restricted stock units using the treasury stock method; and (iii) if dilutive, performance-based and market-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 of outstanding equity awards and the average unrecognized compensation cost during the period. The treasury stock method assumes that a company uses the proceeds from the exercise of an equity award to repurchase common stock at the average market price for the reporting period.

Below is a reconciliation of the weighted average number of shares of common stock outstanding in calculating Diluted EPS (shares in thousands and dollars in millions, except per share amounts) for the periods presented:

	Three months ended September 30,				Nine months ended September 30,
	2019		2018		2019		2018

Basic EPS	$	0.36	$	0.50	$	0.79	$	0.76
Diluted EPS	$	0.36	$	0.49	$	0.78	$	0.75

Potential common shares, consisting of outstanding stock options, service and performance-based restricted stock units (“RSUs”) and market-based restricted stock units (“MSUs”), totaling approximately 7.9 million shares and 5.8 million shares for the three and nine months ended September 30, 2019, respectively, and approximately 3.4 million shares and 7.1 million shares for the three and nine months ended September 30, 2018, respectively, have been excluded from the calculation of Diluted EPS because their effect would have been antidilutive. In addition, potential common shares of certain performance-based awards of approximately 0.7 million shares for both the three and nine months ended September 30, 2019, and approximately 0.5 million shares for both the three and nine months ended September 30, 2018, for which all targets required to trigger vesting had not been achieved, were excluded from the calculation of weighted average shares used to compute Diluted EPS 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.

Stock-Based Award Activity and Valuation

2019 Stock Option Activity

During the nine months ended September 30, 2019, we granted 687,000 service-based non-qualified stock options under the TripAdvisor, Inc. 2018 Stock and Annual Incentive Plan (the “2018 Plan”). Our stock options generally have a term of ten years from the date of grant and typically vest equally over a four-year requisite service period.

A summary of our stock option activity during the nine months ended September 30, 2019, is presented below:

				Weighted		Weighted
				Average		Average
				Exercise		Remaining		Aggregate
	Options			Price Per		Contractual		Intrinsic
	Outstanding			Share		Life		Value

(1)

Inclusive of 120,000 of options which were not converted into shares due to net share settlement in order to cover the aggregate exercise price and the required amount of employee withholding taxes. Potential shares which had been convertible under stock options that were withheld under net share settlement remain in the authorized but unissued pool under the 2018 Plan and can be reissued by the Company. Total payments for the employees’ tax obligations to the taxing authorities due to net share settlements are reflected as a financing activity within the unaudited condensed consolidated statements of cash flows.

(2)

The Company accounts for forfeitures as they occur, rather than estimate expected forfeitures as allowed under GAAP and therefore do not include a forfeiture rate in our vested and expected to vest calculation unless necessary for a performance condition award.

Aggregate intrinsic value represents the difference between the closing stock price of our common stock and the exercise price of outstanding, in-the-money options. Our closing stock price as reported on NASDAQ as of September 30, 2019 was $38.68. The total intrinsic value of stock options exercised for the nine months ended September 30, 2019 and 2018 was $2 million and $7 million, respectively.

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

MSUs provide for vesting based upon the Company’s total shareholder return, or TSR, performance over the period commencing January 1, 2019 through December 31, 2021 relative to the TSR performance of the Nasdaq Composite Total Return Index. Based upon actual attainment relative to the target performance metric, the grantee has the ability to receive up to 200% of the target number of MSUs originally granted, or to be issued none at all. These MSUs were granted under the 2018 Plan.

A Monte-Carlo simulation model, which simulated the present value of the potential outcomes of future stock prices and TSR of the Company and the Nasdaq Composite Total Return Index over the performance period, was used to calculate the grant-date fair value of our MSU awards. The estimated grant-date fair value of these awards is being amortized on a straight-line basis over the requisite service period through December 31, 2021.

Total current income tax benefits associated with the exercise or settlement of TripAdvisor stock-based awards held by our employees was $1 million and $23 million during the three and nine months ended September 30, 2019, respectively, and $1 million and $10 million during the three and nine months ended September 30, 2018, respectively.

(1)	As of September 30, 2019 and December 31, 2018, our restricted cash, which primarily consists of escrowed security deposits, was not material and is included in other long-term assets on our unaudited condensed consolidated balance sheets.

(2)	As of September 30, 2019 and December 31, 2018, any unrealized gains or losses related to our marketable securities were not material.

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 of purchase. 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 September 30, 2019 and December 31, 2018, respectively.

For assets and liabilities required to be reported at fair value, GAAP provides a hierarchy that prioritizes inputs to valuation techniques used to measure fair value into three broad levels:

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

Level 2—Valuations are based on observable inputs other than quoted market 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.

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

There were no material realized gains or losses related to the sales of our marketable securities for both the three and nine months ended September 30, 2019 and 2018. Realized gains and losses on the sale of securities are determined by specific identification of each security’s cost basis. We consider any unrealized loss position in our available-for-sale marketable debt securities to be temporary in nature and do not consider any of these investments other-than-temporarily impaired as of both September 30, 2019 and December 31, 2018.

Derivative Financial Instruments

We typically use forward contracts to reduce the effects of foreign currency exchange rate fluctuations on our cash flows primarily for the Euro versus the U.S. Dollar. Counterparties to our forward contracts 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. For the three and nine months ended September 30, 2019 and 2018, respectively, our forward contracts have not been designated as hedges and generally had maturities of less than 90 days. We do not use derivatives for trading or speculative purposes.

Our outstanding or unsettled forward contracts were carried at fair value on our unaudited condensed consolidated balance sheets at September 30, 2019 and December 31, 2018. We measure the fair value of our outstanding or unsettled derivatives 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. We recognize any gain or loss resulting from the change in fair value of our foreign currency forward contracts in interest income and other, net on our unaudited condensed consolidated statement of operations. We recorded a net gain of $1 million for both the three and nine months ended September 30, 2019, respectively, and a net loss of $3 million for the nine months ended September 30, 2018, related to our forward contracts.

The following table shows the notional principal amounts of our outstanding derivative instruments as of the periods presented:

	September 30, 2019		December 31, 2018
	(in millions)
Foreign currency exchange - forward contracts (1) (2)	$	35	$	13

(1)	Our derivative contracts address foreign currency exchange fluctuations for the Euro versus the U.S. dollar. The Company had five outstanding derivative contracts as of September 30, 2019 and two outstanding derivative contracts as of December 31, 2018.

(2)

The fair value of our outstanding derivatives as of September 30, 2019 was not material and is included in prepaid expenses and other current assets on our unaudited condensed consolidated balance sheets. The fair value of our outstanding derivatives as of December 31, 2018 was not material and is included in accrued expenses and other current liabilities on our unaudited condensed consolidated balance sheets.

Other Financial Instruments

Other financial instruments not measured at fair value on a recurring basis include accounts receivable and contract assets, accounts payable, deferred merchant payables, and accrued and other current liabilities. The carrying amount of these financial instruments approximate their fair value because of the short maturity of these instruments as reported on our unaudited condensed consolidated balance sheets as of September 30, 2019 and December 31, 2018.

In addition, we hold investments in equity securities of privately-held companies that do not have a readily determinable fair value. As of September 30, 2019 and December 31, 2018, the total carrying value of our equity investments in these privately-held companies was $14 million and $12 million, respectively, and is included in other long-term assets on our unaudited condensed consolidated balance sheets. Our policy is to measure these investments at cost less impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Such observable price changes may include instances where the investee issues equity securities to new investors, thus creating a new indicator of fair value, as an example. On a quarterly basis, we perform a qualitative assessment considering impairment indicators to evaluate whether these investments are impaired and also monitor for any observable price changes. During the three and nine months ended September 30, 2019 and 2018, we did not record any impairment loss on these equity investments or identify any observable price change indicators.

The Company did not have any material assets or liabilities measured at fair value on a recurring basis using the Level 3 unobservable inputs at both September 30, 2019 and December 31, 2018.

Goodwill And Intangible Assets Disclosure [Abstract]

Goodwill

NOTE 8: GOODWILL

We assess goodwill, which is not amortized, for impairment annually during the fourth quarter, or more frequently, if events and circumstances indicate impairment may have occurred. We test goodwill for impairment at the reporting unit level. Goodwill is assigned to reporting units that are expected to benefit from the synergies of the business combination as of the acquisition date. Once goodwill has been allocated to the reporting units, it no longer retains its identification with a particular acquisition and becomes identified with the reporting unit in its entirety. Accordingly, the fair value of the reporting unit as a whole is available to support the recoverability of its goodwill. We evaluate our reporting units when changes in our operating structure occur, and if necessary, reassign goodwill using a relative fair value allocation approach.

Subsequent to our prior annual impairment test in the fourth quarter of 2018 the composition of our reportable segments has been revised, as discussed in “Note 15: Segment Information.” Prior to implementing the revised segment reporting structure in the first quarter of 2019, our previously disclosed Hotel segment was considered a single reporting unit. Following the change in reportable segments, our legacy Hotel reporting unit was split into four distinct reporting units – (1) Hotels, Media & Platform, (2) SmarterTravel, (3) Flights, Cruises and Car Rentals; and (4) TripAdvisor China for the purposes of goodwill impairment testing. As a result, we first performed a qualitative assessment on our previous Hotel reporting unit prior to implementing the revised segment reporting structure and determined that it was more likely than not that the fair value of this reporting unit was greater than the carrying value; which was consistent with our conclusion in the fourth quarter of 2018. We then performed a goodwill impairment test for each of the new reporting units upon the change in reportable segments using a quantitative assessment. We concluded the estimated fair values were significantly in excess of the carrying values for these reporting units. We also performed sensitivity analyses, such as calculating estimated fair values using different rates for the weighted-average cost of capital and long-term rates of growth in the income approach and different revenue/income multiples in our market approach and the estimated fair values remained in excess of the carrying values. Therefore, no indications of impairment were identified as a result of these changes in the first quarter of 2019.

Management exercised significant judgment related to the above assessment, including the identification of reporting units, reassignment of assets and liabilities to the new reporting units, reassignment of goodwill to the new reporting units using the relative fair value method, and determination of the fair value of new reporting units. The fair value of our reporting units are generally estimated using an equal weighting of a market approach by using public company multiples and/or other precedent transactions; and a discounted cash flow methodology. The discounted cash flows model indicates the fair value of the reporting units based on the present value of the cash flows that we expect the reporting units to generate in the future. This analysis requires significant judgment, including estimation of future cash flows, which is dependent on internal forecasts, the estimation of the long-term growth rate and profitability of the reporting unit, determination of the Company's weighted average cost of capital and income tax rates. Our significant estimates in the market approach model include identifying similar companies with comparable business factors such as size, growth, profitability, risk and return on investment and assessing comparable revenue and/or income multiples in estimating the fair value of the reporting units. Changes in these estimates and assumptions could materially affect the estimated fair value of the reporting unit, potentially resulting in a non-cash impairment charge.

The following table summarizes our goodwill activity by reportable segment for the periods presented:

	Hotel			Non-Hotel			Hotels, Media & Platform		Experiences & Dining			Other (3)			Total

NOTE 9: DEBT

2015 Credit Facility

We are party to a credit agreement with a group of lenders which, among other things, provides for a $1.2 billion unsecured revolving credit facility (the “2015 Credit Facility”) with a maturity date of May 12, 2022. Borrowings under the 2015 Credit Facility generally bear interest, at the Company’s option, at a rate per annum equal to either (i) the Eurocurrency Borrowing rate, or the adjusted LIBO rate for the interest period in effect for such borrowing; plus an applicable margin ranging from 1.25% to 2.00% (“Eurocurrency Spread”), based on the Company’s leverage ratio; or (ii) the Alternate Base Rate (“ABR”) Borrowing, which is the greatest of (a) the Prime Rate in effect on such day, (b) the New York Fed Bank Rate in effect on such day plus 1/2 of 1.00% per annum and (c) the Adjusted LIBO Rate (or LIBO rate multiplied by the Statutory Reserve Rate) for an interest period of one month plus 1.00%; in addition to an applicable margin ranging from 0.25% to 1.00% (“ABR Spread”), based on the Company’s leverage ratio. The Company may borrow from the 2015 Credit Facility in U.S. dollars, Euros and British pound sterling. In addition, our 2015 Credit Facility includes $15 million of borrowing capacity available for letters of credit and $40 million for Swing Line borrowings on same-day notice. As of September 30, 2019, we had issued $3 million of outstanding letters of credit under the 2015 Credit Facility. We are also required to pay a quarterly commitment fee, at an applicable rate ranging from 0.15% to 0.30%, on the daily unused portion of the revolving credit facility for each fiscal quarter and additional fees in connection with the issuance of letters of credit. As of September 30, 2019, our unused revolver capacity was subject to a commitment fee of 0.15%, given the Company’s leverage ratio.

As of both September 30, 2019 and December 31, 2018, the Company had no outstanding borrowings under the 2015 Credit Facility. During the nine months ended September 30, 2018, the Company made a net repayment of $230 million on our 2015 Credit Facility. These net repayments were primarily made from a one-time cash repatriation of $325 million of foreign earnings to the United States during the first quarter of 2018. Total interest and commitment fees recorded on our 2015 Credit Facility were not material for both the three months ended September 30, 2019 and 2018, respectively. We recorded total interest and commitment fees on our 2015 Credit Facility of $1 million and $2 million for the nine months ended September 30, 2019 and 2018, respectively, to interest expense on our unaudited condensed consolidated statements of operations.

There is no specific repayment date prior to the maturity date for any borrowings under this credit agreement. We may voluntarily repay any outstanding borrowing under the 2015 Credit Facility at any time without premium or penalty, other than customary breakage costs with respect to Eurocurrency loans. Additionally, the Company believes that the likelihood of the lender exercising any subjective acceleration rights, which would permit the lenders to accelerate repayment of any outstanding borrowings, is remote. As such, we classify any borrowings under this facility as long-term debt. The 2015 Credit Facility contains a number of covenants that, among other things, restrict our ability to: incur additional indebtedness, create liens, enter into sale and leaseback transactions, engage in mergers or consolidations, sell or transfer assets, pay dividends and distributions, make investments, loans or advances, prepay certain subordinated indebtedness, make certain acquisitions, engage in certain transactions with affiliates, amend material agreements governing certain subordinated indebtedness, and change our fiscal year. The 2015 Credit Facility also requires us to maintain a maximum leverage ratio and contains certain customary affirmative covenants and events of default, including a change of control. If an event of default occurs, the lenders under the 2015 Credit Facility will be entitled to take various actions, including the acceleration of all amounts due under the 2015 Credit Facility. As of September 30, 2019 and December 31, 2018, we were in compliance with all of our debt covenants.

Chinese Credit Facilities

We are party to a $30 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. This credit facility generally bears interest at a rate based on the People’s Bank of China benchmark, including certain adjustments, which may be made in accordance with market

conditions at the time of borrowing. As of both September 30, 2019 and December 31, 2018, there were no outstanding borrowings under this credit facility.

In September 2019, the Company did not renew our RMB 70,000,000 (approximately $10 million) one-year revolving credit facility with J.P. Morgan Chase Bank (“Chinese Credit Facility—JPM”). We had no outstanding borrowings under this credit facility at the time of termination or at December 31, 2018.

Income Taxes

NOTE 10: INCOME TAXES

Each interim period is considered an integral part of the annual period and, accordingly, we measure our income 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.

The Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”) introduced significant changes to U.S. income tax law. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, and a one-time tax on the mandatory deemed repatriation of cumulative foreign earnings (the “Transition Tax”) as of December 31, 2017.

Our effective tax rate for the three and nine months ended September 30, 2019 was 31.5% and 36.4%, respectively. Our effective tax rate for the three and nine months ended September 30, 2018 was 20.7% and 30.0%, respectively. The change in our effective tax rate during the three months ended September 30, 2019, when compared to the same period in 2018, was primarily due to changes in foreign valuation allowances, a lower benefit from the recognition of excess tax benefits of stock-based compensation, and a change in the relative mix of pretax income among jurisdictions. The change in our effective tax rate during the nine months ended September 30, 2019, when compared to the same period in 2018, was primarily due to the recognition in the second quarter of 2019 of a cumulative income tax expense of $15 million related to the cumulative benefit taken for excluding stock-based compensation from our inter-company cost-sharing arrangements (refer to the discussion below of Altera Corporation (“Altera”) litigation with the Internal Revenue Service (“IRS”) for more information regarding this adjustment), offset by a higher benefit from the recognition of excess tax benefits of stock-based compensation.

Our policy is to recognize accrued interest and penalties related to unrecognized tax benefits and income tax liabilities as part of our income tax expense. As of September 30, 2019, we had an accrued interest liability of $19 million, net of federal and state benefit, and no penalties have been accrued.

By virtue of consolidated income tax returns previously filed with Expedia, we are currently under an IRS audit for the 2009, 2010 and short-period 2011 tax years. We are separately under examination by the IRS for the short-period 2011 and 2012-2016 tax years, under an employment tax audit by the IRS for the 2013 and 2014 tax years, and have various ongoing audits for state income tax returns. These audits include questioning of the timing and the amount of income and deductions and the allocation of income among various tax jurisdictions. These examinations may lead to proposed or ordinary course adjustments to our taxes. We are no longer subject to tax examinations by tax authorities for years prior to 2009. As of September 30, 2019, no material assessments have resulted, except as noted below regarding our 2009, 2010, and 2011 IRS audit with Expedia and our 2012 and 2013 standalone IRS audit.

In January 2017 and April 2019, as part of the IRS audit of Expedia, we received Notices of Proposed Adjustment from the IRS for the 2009, 2010, and 2011 tax years. Subsequently, in September 2019, as part of TripAdvisor’s standalone audit, we received Notices of Proposed Adjustment from the IRS for the 2012 and 2013 tax years. These proposed adjustments are related to certain transfer pricing arrangements with our foreign subsidiaries, and would result in an increase to our worldwide income tax expense in an estimated range of $50 million to $55 million at the close of the audit if the IRS prevails, after consideration of competent authority relief, exclusive of interest and penalties and potential reductions in transition tax, as part of the 2017 Tax Act, which could be significant. We disagree with the proposed adjustments and we intend to defend our position through applicable administrative and, if necessary, judicial remedies. Our policy is to review and update tax reserves as facts and circumstances change. Based on our interpretation of the regulations and available case law, we believe the position we have taken with regard to transfer pricing with our foreign subsidiaries is sustainable. In addition to the risk of additional tax for 2009 through 2013 transactions, if the IRS were to seek transfer pricing adjustments of a similar nature for transactions in subsequent years, we would be subject to significant additional tax liabilities.

In July 2015, the United States Tax Court (the “Court”) issued an opinion favorable to Altera with respect to Altera’s litigation with the IRS. This opinion was submitted as a final decision under Tax Court Rule 155 during December 2015. The litigation relates to the treatment of stock-based compensation expense in an inter-company cost-sharing arrangement with Altera’s foreign subsidiary. In its opinion, the Court accepted Altera’s position of excluding stock-based compensation from its inter-company cost-sharing

arrangement. The IRS appealed the Court decision on February 19, 2016. On June 7, 2019, a three-judge panel from the Ninth Circuit Court of Appeals reversed the Court’s decision and upheld the validity of the Treasury regulation (Reg. sec. 1.482-7A(d)(2)) requiring stock-based compensation costs to be included in the costs shared in a cost-sharing arrangement. Based on this Ninth Circuit Court of Appeals decision, we recorded a cumulative income tax expense of $15 million during the three months ended June 30, 2019, which was a reversal of income tax benefits taken by the Company since the Court’s 2015 opinion. On July 22, 2019, Altera requested a rehearing before the full Ninth Circuit. As a result, the final outcome of the case is uncertain. If the June 7, 2019 Ninth Circuit Court of Appeals decision is reversed, we would anticipate recording an income tax benefit at that time. The Company will continue to monitor this matter and related potential impacts to its consolidated financial statements.

Legal Proceedings

In the ordinary course of business, we are parties to regulatory and legal matters, including threats thereof, arising out of our operations. These matters may involve claims involving patent and intellectual property rights (including alleged infringement of third-party intellectual property rights), tax matters (including value-added, excise, transient occupancy and accommodation taxes), regulatory compliance (including competition, consumer matters and data privacy), defamation and other claims. 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 statements of operations. We provide disclosures in the notes to the consolidated financial statements for loss contingencies that do not meet both of these conditions if there is a reasonable possibility that a loss may have been incurred that would be material to the consolidated financial statements. We base accruals on the best information available at the time which can be highly subjective. Although occasional adverse decisions or settlements may occur, we do not believe that the final disposition of any of these matters will have a material adverse effect on our business. However, the final outcome of these matters could vary significantly from our estimates. Finally, 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. All legal fees incurred by the Company related to any regulatory and legal matters are expensed in the period incurred.

Income Taxes

We are under audit by the IRS and various other domestic and foreign tax authorities with regards to income tax matters. We have reserved for potential adjustments to our provision for income taxes that may result from examinations by, or any negotiated agreements with, these tax authorities. Although we believe our tax estimates are reasonable, the final determination of audits could be materially different from our historical income tax provisions and accruals. The results of an audit could have a material effect on our financial position, results of operations, or cash flows in the period for which that determination is made. Refer to “Note 10: Income Taxes” for further information on potential contingencies surrounding income taxes.

We intend to indefinitely reinvest the remaining foreign undistributed earnings although we will continue to evaluate the impact of the 2017 Tax Act on our capital deployment within and outside the U.S. Should we distribute, or be treated under certain U.S. tax rules as having distributed, the earnings of foreign subsidiaries in the form of dividends or otherwise, we may be subject to certain

income taxes or tax benefits, which are not expected to be material.

Equity [Abstract]

Stockholders' Equity

NOTE 13: STOCKHOLDERS’ EQUITY

On January 31, 2018, our Board of Directors authorized a repurchase of up to $250 million of our shares of common stock under a share repurchase program. This share repurchase program has no expiration date but may be suspended or terminated by our Board of Directors at any time. Our Board of Directors authorized and directed management, working with the Executive Committee of our Board of Directors, to affect the share repurchase program in compliance with applicable legal requirements.

The Company did not repurchase any shares of outstanding common stock during the three and nine months ended September 30, 2019, respectively, and during the three months ended September 30, 2018 under the share repurchase program. During the nine months ended September 30, 2018, we repurchased 2,582,198 shares of outstanding common stock under the share repurchase program at an aggregate cost of $100 million, or an average share price of $38.73, exclusive of fees and commissions. As of both September 30, 2019 and December 31, 2018, there were 12,056,688 shares of the Company’s common stock held in treasury with an aggregate cost of $547 million. As of September 30, 2019, we had a remaining $150 million available to repurchase shares of our common stock under this share repurchase program.

On November 1, 2019, our Board of Directors authorized the repurchase of an additional $100 million of shares of our common stock under our existing share repurchase program, which increased the amount available to the Company under this share repurchase program to $250 million.

Related Party Transactions

NOTE 14: RELATED PARTY TRANSACTIONS

We consider Liberty TripAdvisor Holdings, Inc. (“LTRIP”) a related party. As of September 30, 2019, LTRIP beneficially owned approximately 18.2 million shares of our common stock and 12.8 million shares of our Class B common stock, which constitute 14.3% of the outstanding shares of common stock and 100% of the outstanding shares of Class B common stock. Assuming the conversion of all of LTRIP’s shares of Class B common stock into common stock, LTRIP would beneficially own 22.2% of the outstanding common stock. Because each share of Class B common stock is entitled to ten votes per share and each share of common stock is entitled to one vote per share, LTRIP may be deemed to beneficially own equity securities representing 57.4% of our voting power.

We had no related party transactions with LTRIP during both the three and nine months ended September 30, 2019 and 2018.

Segment Reporting [Abstract]

Segment Information

NOTE 15: SEGMENT INFORMATION

Beginning in the first quarter of 2019 we have two reportable segments: (1) Hotels, Media & Platform; and (2) Experiences & Dining. Our Hotels, Media & Platform reportable segment includes the following revenue sources: (1) TripAdvisor-branded hotels revenue – primarily consisting of TripAdvisor-branded hotel metasearch auction-based revenue, transaction revenue from our hotel instant booking feature, subscription-based advertising and hotel sponsored placements advertising revenue; and (2) TripAdvisor-branded display and platform revenue – consisting of TripAdvisor-branded display-based revenue. Our focus within the Hotels, Media & Platform reportable segment is to generate profit while driving increased customer and client engagement with, and high-margin media advertising revenue from, the TripAdvisor platform. Our Experiences & Dining reportable segment, which includes an aggregation of our Experiences and Restaurants operating segments, reflects our ongoing investment focus to drive revenue growth and to reinforce our market leading position in these growing offerings. All remaining business units have been combined into and reported as “Other”, which includes Rentals, Flights/Cruises/Car Rentals, SmarterTravel, and TripAdvisor China, as none of these businesses meet the quantitative thresholds and other criteria to qualify as reportable segments, and therefore are combined and disclosed as Other.

All direct general and administrative costs are included in the applicable segments and business units; however, all corporate general and administrative costs are included in the Hotels, Media & Platform reportable segment. In addition, the Hotels, Media & Platform reportable segment includes all TripAdvisor-related brand advertising expenses (primarily television advertising), and technical infrastructure and other costs supporting the TripAdvisor platform.

The nature of the services provided and revenue recognition policies are summarized by reported segment in “Note 3: Revenue Recognition.” All prior period segment disclosure information has been reclassified to conform to the current reporting structure in this Form 10-Q. These reclassifications had no effect on our unaudited condensed consolidated financial statements in any period.

Adjusted EBITDA is our segment profit measure and a key measure used by our management and Board of Directors to understand and evaluate the operating performance of our business and on which internal budgets and forecasts are based and approved. 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 amortization of internal use software and website development; (4) amortization of intangible assets; (5) stock-based compensation and other stock-settled obligations; (6) goodwill, long-lived asset and intangible asset impairments; (7) legal reserves and settlements; and (8) non-recurring expenses and income.

The following tables present our segment information for the three and nine months ended September 30, 2019 and 2018 and includes a reconciliation of Adjusted EBITDA to Net Income. We record depreciation of property and equipment, including amortization of internal-use software and website development, amortization of intangible assets, stock-based compensation and other stock-settled obligations, legal reserves and settlements, other income (expense), net, other non-recurring expenses and income, net, and income taxes, which are excluded from segment operating performance, in corporate and unallocated. In addition, we do not report our assets, capital expenditures and related depreciation expense by segment as our CODM does not use this information to evaluate operating segments. Accordingly, we do not regularly provide such information by segment to our CODM. Intersegment revenue is not material and is included in Other.
