PART I Item 1. Business Our mission is to help people experience the world. We seek to achieve our mission by providing consumers, travel service providers and restaurantswith worldwide leadership in online reservation and related services. We operate six primary, independently managed brands:•Booking.com - the world’s leading brand for booking online accommodation reservations, based on room nights booked.•priceline.com - a leading hotel, rental car, airline ticket and vacation package reservation service in the United States.•KAYAK - a leading meta-search service allowing consumers to easily search and compare travel itineraries and prices, including airline ticket,accommodation and rental car reservation information.•agoda.com - a leading accommodation reservation service catering primarily to consumers in the Asia-Pacific region.•Rentalcars.com - a leading worldwide rental car reservation service.•OpenTable - a leading provider of restaurant reservation and information services to consumers and restaurant reservation management servicesto restaurants.Our business is driven primarily by international results, which consist of the results of Booking.com, agoda.com and Rentalcars.com and theinternational businesses of KAYAK and OpenTable (in each case regardless of where the consumer resides, where the consumer is physically located whileusing our services or the location of the travel service provider or restaurant). During the year ended December 31, 2016, our international business (thesubstantial majority of which is generated by Booking.com) represented approximately 88% of our consolidated gross profit. A significant majority of ourgross profit is earned in connection with facilitating accommodation reservations. See Note 16 to the Consolidated Financial Statements for more geographicinformation.The Priceline Group Inc. was formed as a Delaware limited liability company in 1997 and was converted into a Delaware corporation in July 1998. On April 1, 2014, the Company changed its name from priceline.com Incorporated to The Priceline Group Inc. Our common stock is listed on the NASDAQGlobal Select Market under the symbol "PCLN." Our principal executive offices are located at 800 Connecticut Avenue, Norwalk, Connecticut 06854. Werefer to our company and all of our subsidiaries and brands collectively as "The Priceline Group," the "Company," "we," "our" or "us."The Priceline Group Business Model We derive substantially all of our revenues and gross profit from the following sources:•Commissions earned from facilitating reservations of accommodations, rental cars, cruises and other travel services on an agency basis;•Transaction gross profit on a merchant basis and customer processing fees from our accommodation, rental car, airline ticket and vacationpackage reservation services;•Advertising revenues primarily earned by KAYAK from sending referrals to online travel companies ("OTCs") and travel service providers, aswell as from advertising placements on KAYAK's websites and mobile apps;1 •Beginning on July 24, 2014, reservation revenues paid by restaurants for diners seated through OpenTable's online reservation service,subscription fees for restaurant reservation management services provided by OpenTable and other OpenTable revenues; and•Damage excess waiver fees, travel insurance fees and global distribution system ("GDS") reservation booking fees, in each case related to certainof our travel services.Our priceline.com brand offers merchant Name Your Own Price® opaque travel services, which are recorded in revenue on a "gross" basis and haveassociated cost of revenue. All of our other services are recorded in revenue on a "net" basis and have no associated cost of revenue. Therefore, revenueincreases and decreases are impacted by changes in the mix of our revenues between Name Your Own Price® travel services and other services. Gross profitreflects the commission or net margin earned for all of our services. Consequently, gross profit is an important measure to evaluate growth in our businessbecause, in contrast to our revenues, it is not affected by the different methods of recording revenue and cost of revenue between our Name Your Own Price®travel reservation services and our other services. For the year ended December 31, 2016, we had gross profit of approximately $10.3 billion comprised of "agency" gross profit, "merchant" grossprofit, and "advertising and other" gross profit. Agency gross profit is derived from travel-related transactions where we do not facilitate payments for thetravel services provided. Agency gross profit, which represented the majority of our total gross profit in 2016, consists primarily of: (1) travel reservationcommissions; (2) certain GDS reservation booking fees and (3) travel insurance fees. Merchant gross profit is derived from services where we facilitatepayments for the travel services provided, and consists of: (1) transaction gross profit representing the amount charged to a consumer, less the amountcharged to us by travel service providers, and travel reservation commissions in connection with our merchant retail and Express Deals® travel reservationservices; (2) transaction revenues representing the price of Name Your Own Price® reservations charged to a customer (with a corresponding travel serviceprovider cost recorded in cost of revenues); (3) ancillary fees, including damage excess waiver and travel insurance fees and certain GDS reservation bookingfees and (4) customer processing fees. Advertising and other revenues are derived primarily from (1) revenues earned by KAYAK for (a) sending referrals toOTCs and travel service providers and (b) advertising placements on KAYAK's websites and mobile apps; (2) revenues earned by OpenTable for (a)reservation fees paid by restaurants for diners seated through OpenTable's online reservation service and (b) subscription fees earned by OpenTable forrestaurant reservation management services; (3) revenues earned by priceline.com for advertising on its websites; and (4) revenues generated byBooking.com's BookingSuite branded accommodation marketing and business analytics services. See Note 2 to our Consolidated Financial Statements formore information.The Priceline Group Strategy We aim to achieve our mission to help people experience the world through global leadership in online travel and restaurant reservation and relatedservices. We focus on relentless innovation and a commitment to serve both consumers and our travel service provider and restaurant partners withunmatched service and best-in-class digital technology. The online travel and dining categories continue to grow as consumer purchasing shifts fromtraditional offline channels to interactive online channels, including mobile channels. Our strategy is to continue to participate broadly in this online growthby expanding our service offerings and markets. In particular, we aim to be the world leader in online travel and restaurant reservation and related services by(a) providing consumers with the best experience, (b) partnering with travel service providers and restaurants to our mutual benefit, (c) operatingentrepreneurial, independent brands that share best practices, and (d) investing in profitable and sustainable growth.•Providing the best consumer experience. We believe that offering consumers an outstanding online experience is essential for our futuresuccess. To accomplish this, we focus on providing consumers with: (a) a variety of intuitive, easy-to-use online travel and restaurantreservation and search services; (b) a continually increasing number, location and variety of accommodations and restaurants available throughour services: (c) informative and useful content, such as pictures, accommodation and restaurant details and reviews; and (d) excellent customerservice. For example, Booking.com increasingly provides reservation services for accommodations other than hotels, such as vacation rentals.Booking.com included over 1,115,000 properties on its website as of December 31, 2016, which included over 568,000 vacation rentalproperties (updated property counts are available on the Booking.com website). Further, we endeavor to provide excellent customer service in avariety of ways, including through our call centers and websites, so that consumers can be confident that booking reservations through us willlead to a positive experience. We are constantly innovating in order to provide a best-in-class user experience with intuitive, easy-to-usewebsites and mobile apps to ensure that we are meeting the needs of online consumers while aiming to exceed their expectations.2 •Partnering with travel service providers and restaurants. We aim to establish mutually beneficial relationships with travel service providersand restaurants around the world. We believe that travel service providers and restaurants benefit from participating in our services byincreasing their distribution channels, demand and inventory utilization in an efficient and cost-effective manner. Travel service providers andrestaurants benefit from our well-known brands and online marketing efforts, expertise in offering an excellent consumer experience through ourwebsites and mobile apps and ability to offer their inventory in markets and to consumers that the travel service provider or restaurant may beunable or unlikely to reach. For example, an independent hotel may not have the means or expertise to market itself to international travelers,including in other languages, to build and operate effective desktop and mobile websites and online reservation services, or to engage insophisticated online marketing techniques. Further, we are increasingly providing services, other than reservations booked through our websitesand mobile apps, designed to help our partners grow their business. For example, Booking.com's BookingSuite services are designed to offeraccommodation providers with affordable marketing and business analytics tools to help them attract customers and more effectively managetheir properties. Similarly, OpenTable is continuously working to improve its reservation management software services to help restaurants moreeffectively manage their reservations and more efficiently market their available tables to diners.•Maintaining multiple, independently managed brands. We employ a strategy of operating multiple, independently managed brands, which webelieve allows us the opportunity to offer our reservation services in ways that appeal to different consumers while maintaining anentrepreneurial, competitive spirit among our brands. We intend to invest resources to support organic growth by all of our brands, whetherthrough increased advertising, geographic expansion, technology innovation or increased access to accommodations, rental cars, restaurants orother services. For example, we spend significant and increasing amounts on performance and brand advertising to acquire customers andestablish and strengthen our brands. We also believe that by operating independently managed brands, we encourage innovation andexperimentation by our brands, which allows us to more quickly discern and adapt to changing consumer behaviors and market dynamics.Although our brands are independently operated, we intend to continue efforts to share best practices, access to travel service provider offeringsand customers across our brands. We believe that by promoting our brands worldwide, sharing accommodation reservation availability andcustomer demand, and applying our industry experiences across brands and markets, we can more effectively expand our reservation servicesglobally and maintain and grow our position as a leading provider of worldwide online travel and restaurant reservation and related services.•Investing in profitable and sustainable growth. We seek to offer online services that meet the needs and the expectations of consumers, travelservice providers and restaurants and that we believe will result in long-term profitability and growth. We intend to accomplish this throughcontinuous investment and innovation, growing our businesses in new and current markets, expanding our services and ensuring that weprovide an appealing, intuitive and easy-to-use consumer experience through our websites and mobile apps. We also may pursue strategictransactions. For example, in 2013 we entered the meta-search business when we acquired KAYAK and in 2014 we entered the online restaurantreservation market when we acquired OpenTable. We regularly evaluate, and may pursue and consummate, other potential strategicacquisitions, partnerships, joint ventures or investments, whether to expand our businesses into complementary areas, expand our currentbusinesses, acquire innovative technology or for other reasons. For example, we have a commercial relationship with, and have made significantfinancial investments in, Ctrip, a leading OTC operating primarily in China.Service OfferingsThrough our online travel reservation services, we connect consumers wishing to make travel reservations with providers of travel services aroundthe world. We offer consumers a broad array of accommodation reservations (including hotels, bed and breakfasts, hostels, apartments, vacation rentals andother properties) through our Booking.com, priceline.com and agoda.com brands. Our priceline.com brand also offers consumers reservations for rental cars,airline tickets, vacation packages and cruises. We offer rental car reservations worldwide through Rentalcars.com. We also allow consumers to easily comparetravel reservation information, such as airline ticket, hotel reservation and rental car reservation information, from hundreds of travel websites at once throughKAYAK. We provide restaurants with reservation management services and consumers with the ability to make restaurant reservations at participatingrestaurants through OpenTable.Booking.com. Booking.com is the world's leading brand for booking online accommodation reservations, based on room nights booked, withoperations worldwide and headquarters in the Netherlands. As of December 31, 2016, Booking.com offered accommodation reservation services for over1,115,000 properties in over 220 countries and territories on its various websites and in over 40 languages, which includes over 568,000 vacation rentalproperties (updated property counts are3 available on the Booking.com website). Vacation rentals generally consist of, among others, properties categorized as single-unit and multi-unit villas,apartments, "aparthotels" (which are apartments with a front desk and cleaning service) and chalets and are generally self-catered (i.e., include a kitchen),directly bookable properties. Accommodation providers participate in Booking.com, which operates primarily under an agency model, by filing rates andinformation about the property in Booking.com's proprietary extranet. In addition, Booking.com offers website and other marketing services and businessanalytics to accommodation providers as part of its BookingSuite initiative.Priceline.com. Priceline.com offers online travel reservation services primarily in the United States and is headquartered in Norwalk, Connecticut.Through priceline.com, we offer consumers hotel, rental car and airline ticket reservation services, as well as vacation packages and cruises. Priceline.com is aleader in the discount travel reservation business, including through its pioneering Name Your Own Price® and Express Deals® "opaque" offerings wherecertain elements of the service, including the identity of the travel service provider, are not disclosed to the consumer prior to making a reservation. Webelieve that the combination of priceline.com's retail and opaque models allows it to provide a broad array of options to value-conscious consumers.Priceline.com operates under both a merchant and agency model.KAYAK. KAYAK, headquartered in Stamford, Connecticut, provides an online price comparison service (often referred to as "meta-search") thatallows consumers to easily search and compare travel itineraries and prices, including airline ticket, accommodation reservation and rental car reservationinformation, from hundreds of travel websites at once. KAYAK derives revenues from sending referrals to OTCs and travel service providers and fromadvertising placements on its websites and mobile apps. KAYAK offers its services in approximately 40 countries, with the United States being its largestmarket.Agoda.com. Agoda.com is a leading online accommodation reservation service catering primarily to consumers in the Asia-Pacific region, withheadquarters in Singapore and operations in Bangkok, Thailand and throughout the region. Accommodation providers participate in agoda.com, whichoperates primarily under a merchant model, by filing rates and information about the property in agoda.com's proprietary extranet. Rentalcars.com. Rentalcars.com is a leading worldwide online rental car reservation service and is headquartered in Manchester, England.Rentalcars.com, which operates primarily under a merchant model, offers online rental car reservation services allowing consumers to make rental carreservations in approximately 49,000 locations throughout the world, with customer support provided in 40 languages. Consumers using Rentalcars.com canbook a full range of vehicles online through Rentalcars.com's website or mobile app, or they can reserve their cars by phone. OpenTable. In July 2014, we acquired OpenTable, a leading brand for booking online restaurant reservations. Headquartered in San Francisco,California, OpenTable provides online restaurant reservation services to consumers and reservation management services to restaurants. OpenTable doesbusiness primarily in the United States, though it intends to continue to invest in expanding its international offerings.Marketing and Brand Awareness Booking.com, priceline.com, KAYAK, agoda.com, Rentalcars.com and OpenTable have established widely used and recognized e-commerce brandsthrough marketing and promotional campaigns. Both our performance advertising expense and brand advertising expense have increased significantly inrecent years, a trend we expect to continue. During 2016, our total performance advertising expense was approximately $3.5 billion, primarily related to theuse of online search engines (primarily Google), meta-search and travel research services and affiliate marketing to generate traffic to our websites. We alsoinvested approximately $296 million in brand advertising during 2016. We intend to continue a strategy of promoting brand awareness through both onlineand offline advertising efforts, including by expanding brand campaigns into additional markets. We expense the substantial majority of our advertisingactivities as the expense is incurred, which is typically in the quarter in which reservations are booked, but recognize most of our gross profit when theconsumer's travel or dining experience is completed. As a result, performance advertising expense may not be recognized in the same period as the associatedgross profit.Competition We compete globally with both online and traditional travel and restaurant reservation and related services. The markets for the services we offer areintensely competitive, a trend we expect to continue, and current and new competitors can launch new services at a relatively low cost. Some of our currentand potential competitors, such as Google, Apple, Alibaba, Tencent, Amazon and Facebook, have access to significantly greater and more diversifiedresources than we do, and they may be able to leverage other aspects of their businesses (e.g., search or mobile device businesses) to enable them to competemore effectively with us. For example, Google has entered various aspects of the online travel market, including by establishing a4 flight meta-search product (“Google Flights”) and a hotel meta-search business ("Hotel Ads") that are growing rapidly, as well as its "Book on Google"reservation functionality. We currently, or may potentially in the future, compete with a variety of companies, including:•online travel reservation services such as Expedia, Hotels.com, Hotwire, Orbitz, Travelocity, Wotif, Cheaptickets, ebookers, HotelClub, RatesToGoand CarRentals.com, which are owned by Expedia; Hotel Reservation Service (HRS) and hotel.de, which are owned by Hotel Reservation Service;and AutoEurope, CarTrawler, Ctrip (in which we hold a minority interest), eLong (in which Ctrip has acquired a significant minority ownershipinterest), Meituan, ezTravel, MakeMyTrip, OYO Rooms, Yatra, Cleartrip, Traveloka, Webjet, Rakuten, Jalan (which is owned by Recruit), ViajaNet,Submarino Viagens, Despegar/Decolar (in which Expedia holds a minority ownership interest), Fliggy (operated by Alibaba), 17u.com,HotelTonight, CheapOair, Mr. and Mrs. Smith and eDreams ODIGEO;•online accommodation search and/or reservation services, such as Airbnb and HomeAway (which is owned by Expedia), currently focused onvacation rental properties and other non-hotel accommodations, including individually owned properties;•large online companies, including search, social networking and marketplace companies such as Google, Facebook, Alibaba, Tencent, Amazon,Baidu and Groupon;•traditional travel agencies, travel management companies, wholesalers and tour operators, many of which combine physical locations, telephoneservices and online services, such as Carlson Wagonlit, American Express, BCD Travel, Concur, Thomas Cook, TUI, Hotelbeds and Tourico (whichhave agreed to merge) and Kuoni as well as thousands of individual travel agencies around the world;•travel service providers such as accommodation providers, rental car companies and airlines, many of which have their own branded websites towhich they drive business, including large hotel chains such as Marriott International, Hilton and Hyatt Hotels, as well as joint efforts by travelservice providers such as Room Key, an online hotel reservation service owned by several major hotel companies;•online travel search and price comparison services (generally referred to as "meta-search" services), such as TripAdvisor, trivago (in which Expediaholds a majority ownership interest), Qunar (which is controlled by Ctrip), Skyscanner (in which Ctrip holds a majority ownership interest), GoogleFlights, Google Hotel Ads and HotelsCombined;•online restaurant reservation services, such as TripAdvisor's LaFourchette, Yelp's SeatMe, Zomato, Bookatable (which is owned by Michelin),Quandoo (which is owned by Recruit) and Resy (in which Airbnb holds a minority investment); and•companies offering new rental car business models or car- or ride-sharing services that affect demand for rental cars, some of which have developedinnovative technologies to improve efficiency of point-to-point transportation and extensively utilize mobile platforms, such as Uber, Lyft, Gett,Zipcar (which is owned by Avis), BlaBlaCar, Didi Chuxing and Ola.TripAdvisor, a leading travel research and review website, Google, the world's largest search engine, and other large, established companies withsubstantial resources and expertise in developing online commerce and facilitating Internet traffic have launched search, meta-search and/or reservationbooking services and may create additional inroads into online travel, both in the United States and internationally. Meta-search services leverage theirsearch technology to aggregate travel search results for the consumer's specific itinerary across travel service provider (e.g., accommodations, rental carcompanies or airlines), OTC and other travel websites and, in many instances, compete directly with us for customers. Meta-search services intend to appealto consumers by showing broader travel search results than may be available through OTCs or other travel websites, which could lead to travel serviceproviders or others gaining a larger share of search traffic. TripAdvisor and trivago, two leading meta-search companies, support their meta-search serviceswith significant brand and performance advertising. Through our KAYAK meta-search service, we compete directly with other meta-search services.Further, meta-search services may evolve into more traditional OTCs by offering consumers the ability to make travel reservations directly throughtheir websites. For example, TripAdvisor allows consumers to make a reservation at some accommodations while staying on TripAdvisor through its "InstantBooking" offering, which includes participation by many of the leading global hotel chains, and facilitates hotel reservations on its transaction websitesTingo and Jetsetter.5 There has been a proliferation of new channels through which accommodation providers can offer reservations. For example, companies such asAirbnb and HomeAway (which is owned by Expedia) offer services providing vacation rental property owners, particularly individuals, an online place to listtheir accommodations where travelers can search and book such properties and compete directly with our vacation rental accommodation services. Airbnbmay also seek to further compete with us by offering hotel and other non-vacation rental accommodations through their online and mobile platforms.Travel service providers, including hotel chains, rental car companies and airlines with which we conduct business, compete with us in onlinechannels to drive consumers to their own websites in lieu of third-party distributors such as us. Travel service providers may charge lower prices and, in someinstances, offer advantages such as loyalty points or special discounts to members of closed user groups (such as loyalty program participants or customerswith registered accounts), any of which could make their offerings more attractive to consumers than our services. Further, consolidation among travel serviceproviders, such as Marriott International's acquisition of Starwood Hotels & Resorts, could result in lower rates of commission paid to OTCs, increaseddiscounting and greater incentives for consumers to join closed user groups as such travel service providers expand their offerings.Google's Android operating system is the leading smartphone operating system in the world. As a result, Google could leverage its Androidoperating system to give its travel services a competitive advantage, either technically or with prominence on its Google Play app store or within its mobilesearch results. Further, Google is the leading Internet search service and has leveraged its search popularity to promote its travel meta-search services.Similarly, Apple, the producer of, among other things, the iPhone and iPad, obtained a patent for "iTravel," a mobile app that would allow a traveler to checkin for a travel reservation. In addition, Apple's iPhone operating system includes "Wallet" (formerly known as "Passbook"), a virtual wallet app that holdstickets, boarding passes, coupons and gift cards, and, along with iTravel, may be indicative of Apple's intent to enter the travel reservations business in somecapacity. Apple has substantial market share in the smartphone category and controls integration of offerings, including travel services, into its mobileoperating system. Apple also has more experience producing and developing mobile apps and has access to greater resources than we have. Apple may use orexpand iTravel, Wallet, Siri (Apple's voice recognition "concierge" service), Apple Pay (Apple's mobile payment system) or another mobile app orfunctionality as a means of entering the travel reservations marketplace. To the extent Apple or Google use their mobile operating systems, app distributionchannels or, in the case of Google, search services, to favor their own travel service offerings, our business and results of operations could be harmed.Operations and Technology Our business is supported by multiple systems platforms, which were designed with an emphasis on scalability, performance and reliability. Theplatforms are largely independent among Booking.com, priceline.com, KAYAK, agoda.com, Rentalcars.com and OpenTable. The software platforms andarchitecture use a variety of tools within each corporate implementation, including server-side Java, C++, ASP, .Net, Perl, PHP, JavaScript and SQL scriptsintegrated with Oracle, MySQL, MongoDB, Cassandra and Microsoft SQL-server database systems. These internal platforms were designed to include openapplication protocol interfaces that can provide connectivity to vendors in the industries in which we operate. These include large global systems, such asaccommodation, airline ticket and rental car reservation systems and financial service providers, as well as individual accommodation service providers, suchas individual hotels. Our applications utilize digital certificates to help us conduct secure communications and transactions, as appropriate. The systems infrastructure and web and database servers of our worldwide operations are primarily hosted in the United Kingdom, Switzerland, theNetherlands, Germany, Singapore, Hong Kong and four locations in the United States, each of which provides network connectivity, networkinginfrastructure, UPS conditioned power and 24-hour monitoring and engineering support typical of hosted data centers. All data center facilities have acontinuous power supply system, generators, redundant servers and multiple back-up systems. Although we take steps to mitigate the effects of any loss orreduction in service at one of our hosting facilities, if a hosting facility were inaccessible or otherwise experienced a disruption in service for any reason, wecould experience a disruption to our services, loss of transactions and revenue and consumer complaints.We provide customer service through a mix of in-house call centers and outsourced third party services.Intellectual Property Over time and through acquisitions, we have assembled a portfolio of patents, trademarks, service marks, copyrights, domain names, and tradesecrets covering our services. We regard the protection of our intellectual property as critical to our success. We protect our intellectual property rights byrelying on national, federal, state and common law rights in the United6 States and internationally, as well as a variety of administrative procedures, regulations, conventions and treaties. We also rely on contractual restrictions toprotect our proprietary rights in our services. We enter into confidentiality and invention assignment agreements with employees and contractors andnondisclosure agreements with parties with whom we conduct business in order to limit access to and disclosure of our proprietary information.As we deem appropriate, we pursue the registration of our intellectual property, such as domain names, trademarks and service marks, in the UnitedStates and internationally. We currently hold various issued U.S. and international patents and pending U.S. and international patent applications. We fileadditional patent applications on new inventions, as we deem appropriate. Effective trademark, copyright, patent, domain name, trade dress and trade secretprotection is expensive to maintain and may require litigation. As we continue to expand internationally, protecting our intellectual property rights and otherproprietary rights involves an increasing number of jurisdictions, a process that is expensive and time-consuming and may not be successful in everylocation. See Part I Item 1A Risk Factors - "We face risks related to our intellectual property."SeasonalityA meaningful amount of our gross bookings are generated early in the year, as customers plan and reserve their spring and summer vacations inEurope and North America. However, we generally do not recognize revenue from these bookings until the travel occurs, which can be in a quarter other thanwhen the reservation is booked. In contrast, we expense the substantial majority of our advertising activities as the expense is incurred, which, in the case ofperformance advertising in particular, is typically in the quarter in which associated reservations are booked. As a result of this potential timing differencebetween when we record advertising expense and when we recognize associated revenue, we have historically experienced our highest levels of profitabilityin the second and third quarters of the year, which is when we experience the highest levels of accommodation checkouts for the year for our European andNorth American businesses. The first quarter of the year is typically our lowest level of profitability and may experience volatility in earnings growth ratesdue to these seasonal timing factors. For our Asia-Pacific business, we experience the highest levels of accommodation bookings in the third and fourthquarters of the year, and the highest levels of travel consumption in the fourth quarter. As the relative growth rates for these businesses fluctuate, the quarterlydistribution of our operating results may vary.In addition, the date on which certain holidays fall can have an impact on our quarterly results. For example, in 2016, our first quarter year-over-yeargrowth rates in revenue, gross profit, operating income and operating margins were positively impacted by Easter falling in the first quarter instead of thesecond quarter, as it did in 2015. Conversely, our second quarter 2016 year-over-year growth rates in revenue, gross profit, operating income and operatingmargins were adversely impacted by Easter falling in the first quarter instead of the second quarter, as it did in 2015. Similarly to 2015, in 2017 Easter willfall in the second quarter instead of the first quarter, and will therefore have a negative effect on our first quarter 2017 year-over-year growth rates and apositive effect on our second quarter 2017 year-over-year growth rates as compared to the same periods in 2016 when Easter fell in the first quarter. Thetiming of other holidays such as Chinese New Year, Carnival and Ramadan can also impact our quarterly year-over-year growth rates.The impact of seasonality can be exaggerated in the short term by the gross bookings growth rate of the business. For example, in periods where ourgross bookings growth rate substantially decelerates, our operating margins typically benefit from relatively less variable advertising expense. In addition,gross profit growth is typically less impacted by decelerating gross bookings growth in the near term due to the benefit of revenue related to reservationsbooked in previous quarters. Conversely, in periods where our gross bookings growth rate accelerates, our operating margins are typically negativelyimpacted by relatively more variable advertising expense. In addition, gross profit growth is typically less impacted by accelerating gross bookings growth inthe near term as a portion of the revenue recognized from such gross bookings will occur in future quarters.Employees As of December 31, 2016, we employed approximately 18,500 employees, of which approximately 3,600 were based in the United States andapproximately 14,900 were based outside the United States. We also retain independent contractors to support our customer service, website contenttranslation and system support functions. We have never had a work stoppage and we consider our relations with our employees to be good. Although we have works councils or employeerepresentatives in certain countries, our U.S. employees are not represented by a labor union and are not covered by a collective bargaining agreement. Ourfuture success will depend, in part, on our ability to continue to attract, integrate, retain and motivate highly qualified technical and managerial personnel,for whom competition is intense.7 See Part I Item 1A Risk Factors -"We rely on the performance of highly skilled personnel; and, if we are unable to retain or motivate key personnel or hire,retain and motivate qualified personnel, our business would be harmed."

Risk Factors The following risk factors and other information included in this Annual Report should be carefully considered. The risks and uncertaintiesdescribed below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe are immaterialmay also impair our business, results of operations or financial condition. If any of the following risks occur, our business, financial condition, operatingresults and cash flows could be materially adversely affected.Declines or disruptions in the travel industry could adversely affect our business and financial performance.Our financial results and prospects are almost entirely dependent upon the sale of travel services. Travel, including accommodation (includinghotels, bed and breakfasts, hostels, apartments, vacation rentals and other properties), rental car and airline ticket reservations, is significantly dependent ondiscretionary spending levels. As a result, sales of travel services tend to decline during general economic downturns and recessions when consumers engagein less discretionary spending, are concerned about unemployment or inflation, have reduced access to credit or experience other concerns or effects thatreduce their ability or willingness to travel. For example, the worldwide recession that began in 2007 led to a weakening in the fundamental demand for ourtravel reservation services and an increase in the number of consumers who canceled existing travel reservations with us. Also during the recession, theaccommodation industry experienced a significant decrease in occupancy rates and average daily rates ("ADRs"). While lower occupancy rates havehistorically resulted in accommodation providers increasing their distribution of accommodation reservations through third-party intermediaries such as us,our remuneration for accommodation reservation transactions changes proportionately with price, and therefore, lower ADRs generally have a negative effecton our accommodation reservation business and a negative effect on our gross profit.Concerns persist about the outlook for the global economy in general, including uncertainty in the European Union and China. Perceived or actualadverse economic conditions, including slow, slowing or negative economic growth, unemployment rates and weakening currencies and concerns overgovernment responses such as higher taxes and reduced government spending, could impair consumer spending and adversely affect travel demand. Further,uncertainty regarding the future of the European Union following the United Kingdom's vote to leave ("Brexit") and concerns regarding certain E.U. memberswith sovereign debt default risks could also negatively affect consumer spending and adversely affect travel demand. At times, we have experiencedvolatility in transaction growth rates, increased cancellation rates and weaker trends in hotel ADRs across many regions of the world, particularly in thosecountries that appear to be most affected by economic uncertainties, which we believe are due at least in part to macro-economic conditions and concerns.Disruptions in the economies of such countries could cause, contribute to or be indicative of deteriorating macro-economic conditions, which in turn couldnegatively affect travel to or from such countries or the travel industry in general and therefore have an adverse impact on our results of operations.These and other macro-economic uncertainties, such as sovereign default risk becoming more widespread, declining oil prices, geopolitical tensionsand differing central bank monetary policies, have led to significant volatility in the exchange rates between the U.S. Dollar and the Euro, the British PoundSterling and other currencies. Significant fluctuations in currency exchange rates, stock markets and oil prices can also impact consumer travel behavior. Forexample, although lower oil prices may lead to increased travel activity as consumers have more discretionary funds and airline fares decrease, recentdeclines in oil prices and stock market volatility may be indicative of broader macro-economic weakness, which in turn could negatively affect the travelindustry and our business.Since the United Kingdom's Brexit vote, global markets and foreign exchange rates have experienced increased volatility, including a sharp declinein the value of the British Pound Sterling as compared to the U.S. Dollar. Upon leaving the European Union, among other things, the United Kingdom couldlose access to the single European Union market and travel between the United Kingdom and European Union countries could be restricted. We could facenew regulatory costs and challenges if U.K. regulations and policies diverge from those of the European Union. Since the timing and terms of the UnitedKingdom's exit from the European Union are unknown, we are unable to predict the effect Brexit will have on our business and results of operations. TheUnited Kingdom's decision to leave the European Union could result in other member countries also determining to leave, which could lead to addedeconomic and political uncertainty and further devaluation or eventual abandonment of the Euro common currency, any of which could have a negativeimpact on travel and therefore our business and results of operations. For the twelve months ended June 30, 2016, U.K. destination gross profit and U.K.source market gross bookings were 10% or less as a share of our business.The uncertainty of macro-economic factors and their impact on consumer behavior, which may differ across regions, makes it more difficult toforecast industry and consumer trends and the timing and degree of their impact on our markets and business, which in turn could adversely affect our abilityto effectively manage our business and adversely affect our results of9 operations. For example, we have experienced an increase in cancellation rates, which we expect to continue and which we believe is due in part to thesemacro-economic factors and a resulting lack of consumer confidence. Increased cancellation rates negatively affect our advertising efficiency and our resultsof operations.In addition, other unforeseen events beyond our control, such as worldwide recession, oil prices, terrorist attacks, unusual or extreme weather ornatural disasters such as earthquakes, hurricanes, tsunamis, floods, droughts and volcanic eruptions, travel-related health concerns including pandemics andepidemics such as Ebola, Zika, Influenza H1N1, avian bird flu, SARS and MERS, political instability, regional hostilities, imposition of taxes or surchargesby regulatory authorities, changes in trade or immigration policies or travel-related accidents, can disrupt travel or otherwise result in declines in traveldemand. Because these events or concerns are largely unpredictable, they can dramatically and suddenly affect travel behavior by consumers, and thereforedemand for our services, which can adversely affect our business and results of operations. For example, our business and operations were negativelyimpacted by the terrorist attacks in Paris in November 2015, Brussels in March 2016, Orlando in June 2016, Nice in July 2016, and Istanbul in July 2016 andJanuary 2017; the coup attempt in Turkey in July 2016; Hurricane Sandy, which disrupted travel in the northeastern United States in late 2012; a majorearthquake, tsunami and nuclear emergency in Japan in 2011; severe flooding in Thailand in October 2011; and disruptive civil unrest in Thailand in 2014.In addition, MERS had an adverse impact on our business in northeast Asia in 2015. Also, since 2015, regional hostilities in the Middle East have spurred anunprecedented flow of migrants from that region to Europe and other areas. As countries respond to the migrant crisis, travel between countries within theEuropean Union and to and from the region could be subject to increased restrictions or the closing of borders, which could negatively impact travel to, fromor within the European Union and adversely affect our business and results of operations. In the United States, the Trump administration has proposed or isconsidering various actions that could affect U.S. trade policy or practices, which in turn could adversely affect travel to or from the United States. Futureterrorist attacks, natural disasters, health concerns, civil or political unrest or other events out of our control such as the ones described above could disruptour business and operations and adversely affect our results of operations.Intense competition could reduce our market share and harm our financial performance.We compete globally with both online and traditional travel and restaurant reservation and related services. The markets for the services we offer areintensely competitive, and current and new competitors can launch new services at a relatively low cost. Some of our current and potential competitors, suchas Google, Apple, Alibaba, Tencent, Amazon and Facebook, have access to significantly greater and more diversified resources than we do, and they may beable to leverage other aspects of their businesses (e.g., search or mobile device businesses) to enable them to compete more effectively with us. For example,Google has entered various aspects of the online travel market, including by establishing a flight meta-search product ("Google Flights") and a hotel meta-search business ("Hotel Ads") that are growing rapidly, as well as its "Book on Google" reservation functionality.We currently, or may potentially in the future, compete with a variety of companies, including:•online travel reservation services such as Expedia, Hotels.com, Hotwire, Orbitz, Travelocity, Wotif, Cheaptickets, ebookers, HotelClub, RatesToGoand CarRentals.com, which are owned by Expedia; Hotel Reservation Service (HRS) and hotel.de, which are owned by Hotel Reservation Service;and AutoEurope, Car Trawler, Ctrip (in which we hold a minority interest), eLong (in which Ctrip has acquired a significant minority ownershipinterest), Meituan, ezTravel, MakeMyTrip, OYO Rooms, Yatra, Cleartrip, Traveloka, Webjet, Rakuten, Jalan (which is owned by Recruit), ViajaNet,Submarino Viagens, Despegar/Decolar (in which Expedia holds a minority interest), Fliggy (operated by Alibaba), 17u.com, HotelTonight,CheapOair, Mr. and Mrs. Smith and eDreams ODIGEO;•online accommodation search and/or reservation services, such as Airbnb and HomeAway (which is owned by Expedia), currently focused onvacation rental properties and other non-hotel accommodations, including individually owned properties;•large online companies, including search, social networking and marketplace companies such as Google, Facebook, Alibaba, Tencent, Amazon,Baidu and Groupon;•traditional travel agencies, travel management companies, wholesalers and tour operators, many of which combine physical locations, telephoneservices and online services, such as Carlson Wagonlit, American Express, BCD Travel, Concur, Thomas Cook, TUI, Hotelbeds and Tourico (whichhave agreed to merge) and Kuoni, as well as thousands of individual travel agencies around the world;10 •travel service providers such as accommodation providers, rental car companies and airlines, many of which have their own branded websites towhich they drive business, including large hotel chains such as Marriott International, Hilton and Hyatt Hotels, as well as joint efforts by travelservice providers such as Room Key, an online hotel reservation service owned by several major hotel companies;•online travel search and price comparison services (generally referred to as "meta-search" services), such as TripAdvisor, trivago (in which Expediaholds a majority ownership interest), Qunar (which is controlled by Ctrip), Skyscanner (in which Ctrip holds a majority interest), Google Flights,Google Hotel Ads and HotelsCombined;•online restaurant reservation services, such as TripAdvisor's LaFourchette, Yelp's SeatMe, Zomato, Bookatable (which is owned by Michelin),Quandoo (which is owned by Recruit) and Resy (in which Airbnb holds a minority interest); and•companies offering new rental car business models or car- or ride-sharing services that affect demand for rental cars, some of which have developedinnovative technologies to improve efficiency of point-to-point transportation and extensively utilize mobile platforms, such as Uber, Lyft, Gett,Zipcar (which is owned by Avis), BlaBlaCar, Didi Chuxing and Ola.TripAdvisor, a leading travel research and review website, Google, the world's largest search engine, and other large, established companies withsubstantial resources and expertise in developing online commerce and facilitating Internet traffic have launched search, meta-search and/or reservationbooking services and may create additional inroads into online travel, both in the United States and internationally. Meta-search services leverage theirsearch technology to aggregate travel search results for the consumer's specific itinerary across travel service provider (e.g., accommodations, rental carcompanies or airlines), online travel company ("OTC") and other travel websites and, in many instances, compete directly with us for customers. Meta-searchservices intend to appeal to consumers by showing broader travel search results than may be available through OTCs or other travel websites, which couldlead to travel service providers or others gaining a larger share of search traffic. TripAdvisor and trivago, two leading meta-search companies, support theirmeta-search services with significant brand and performance advertising. Through our KAYAK meta-search service, we compete directly with other meta-search services. KAYAK depends on access to information related to travel service pricing, schedules, availability and other related information from OTCsand travel service providers. To the extent OTCs or travel service providers do not provide such information to KAYAK, KAYAK's business and results ofoperations could be harmed.Consumers may favor travel services offered by meta-search websites or search companies over OTCs, which could reduce traffic to our travelreservation websites, increase consumer awareness of our competitors' brands and websites and increase our advertising and other customer acquisition costs.To the extent any such consumer behavior leads to growth in our KAYAK meta-search business, such growth may not result in sufficient increases in profitsfrom our KAYAK meta-search business to offset any related decrease in profits experienced by our travel service reservation brands. Further, meta-searchservices may evolve into more traditional OTCs by offering consumers the ability to make travel reservations directly through their websites. For example,TripAdvisor allows consumers to make a reservation at some accommodations while staying on TripAdvisor through its "Instant Booking" offering, whichincludes participation by many of the leading global hotel chains, and facilitates hotel reservations on its transaction websites Tingo and Jetsetter. We havebeen participating in Instant Booking since 2015, however such participation may not result in substantial incremental bookings and could cannibalizebusiness that would otherwise come to us through other ad offerings on TripAdvisor, directly (including after a consumer first visits TripAdvisor) or throughother channels, some of which may be more profitable to us than reservations generated through "Instant Booking." To the extent consumers book travelservices through a service such as Google's "Book on Google," a meta-search website or directly with a travel service provider after visiting a meta-searchwebsite or meta-search utility on a traditional search engine without using an OTC like us, or if meta-search services limit our participation within theirsearch results or evolve into more traditional OTCs, we may need to increase our advertising or other customer acquisition costs to maintain or grow ourreservation bookings and our business and results of operations could be adversely affected.There has been a proliferation of new channels through which accommodation providers can offer reservations. For example, companies such asAirbnb and HomeAway (which is owned by Expedia) offer services providing vacation rental property owners, particularly individuals, an online place to listtheir accommodations where travelers can search and book such properties and compete directly with our vacation rental accommodation services. Airbnbmay also seek to further compete with us by offering hotel and other accommodations through their online and mobile platforms. Further, meta-searchservices may lower the cost for new companies to enter the market by providing a distribution channel without the cost of promoting the new entrant's brandto drive consumers directly to its website. If any of these services are successful in attracting consumers who would otherwise use our services, our businessand results of operations would be harmed.11 Travel service providers, including hotel chains, rental car companies and airlines with which we conduct business, compete with us in onlinechannels to drive consumers to their own websites in lieu of third-party distributors such as us. Travel service providers may charge lower prices and, in someinstances, offer advantages such as loyalty points or special discounts to members of closed user groups (such as loyalty program participants or consumerswith registered accounts), any of which could make their offerings more attractive to consumers than our services. For example, Marriott International, Hilton,Hyatt Hotels, Intercontinental Hotel Group and Choice Hotels International have announced additional initiatives to encourage consumers to bookaccommodations directly through their websites, with increased discounting and incentives. Discounting may increase as competition authorities seek toallow increased pricing flexibility among providers of travel service reservations. We may need to offer similar advantages to maintain or grow ourreservation bookings, which could adversely impact our profitability. Further, consolidation among travel service providers, such as Marriott International'sacquisition of Starwood Hotels & Resorts, could result in lower rates of commission paid to OTCs, increased discounting and greater incentives for consumersto join closed user groups as such travel service providers expand their offerings. If we are not as effective as our competitors (including hotel chains) inoffering discounted prices to closed user groups or if we are unable to entice members of our competitors' closed user groups to use our services, our ability togrow and compete could be harmed.We are exposed to fluctuations in currency exchange rates.We conduct a substantial majority of our business outside the United States but we report our results in U.S. Dollars. As a result, we face exposure toadverse movements in currency exchange rates as the financial results of our international businesses are translated from local currency (principally Eurosand British Pounds Sterling) into U.S. Dollars. Throughout 2015, the U.S. Dollar strengthened significantly year-over-year relative to substantially allcurrencies in which we transact, most notably the Euro, Brazilian Real, British Pound Sterling, Russian Ruble and Australian Dollar. In 2016, the U.S. Dollarcontinued to be stronger year-over-year relative to the British Pound Sterling, Russian Ruble and many other major currencies in which we transact. Since the“Brexit” referendum in the United Kingdom in June 2016, the U.S. Dollar has strengthened significantly against the British Pound Sterling. Potential tax lawchanges, such as a U.S. border adjustment tax on imported goods, could, if implemented, lead to additional foreign exchange rate volatility and potentiallyadditional strengthening of the U.S. dollar. As a result of these currency exchange rate changes, our foreign currency denominated net assets, gross bookings,gross profit, operating expenses and net income have been negatively impacted as expressed in U.S. Dollars, although to a much lesser extent in 2016 than in2015. For example, gross profit from our international operations grew 22.3% for the year ended December 31, 2016 compared to the year endedDecember 31, 2015, but, without the negative impact of changes in currency exchange rates, grew year-over-year on a constant-currency basis byapproximately 25%. If the U.S. dollar strengthens further, our foreign currency denominated net assets, gross bookings, gross profit, operating expenses andnet income when expressed in U.S. dollars would be adversely affected.Recent macro-economic conditions, such as sovereign default risk of certain European Union countries with high levels of sovereign debt, concernaround devaluation or abandonment of the Euro common currency, declining oil prices, Brexit, geopolitical tensions and differing central bank monetarypolicies, have led to significant volatility in the exchange rate between the Euro, the British Pound Sterling, the U.S. Dollar and other currencies. Significantfluctuations in currency exchange rates can affect consumer travel behavior. For example, the strengthening of the U.S. Dollar relative to the Euro in 2015made it more expensive for Europeans to travel to the United States, and dramatic depreciation of the Russian Ruble in 2014 and 2015 made it moreexpensive for Russians to travel to Europe and most other non-Ruble destinations. Consumers traveling from a country whose currency has weakened againstother currencies may book lower ADR accommodations, choose to shorten or cancel their international travel plans or choose to travel domestically ratherthan internationally, any of which could adversely affect our gross bookings, revenues and results of operations, in particular when expressed in U.S. Dollars.Additionally, foreign exchange rate fluctuations on transactions denominated in currencies other than the functional currency result in gains andlosses that are reflected in our financial results.Volatility in foreign exchange rates and its impact on consumer behavior, which may differ across regions, make it more difficult to forecast industryand consumer trends and the timing and degree of their impact on our markets and business, which in turn could adversely affect our ability to effectivelymanage our business and adversely affect our results of operations.We face risks related to the growth rate and the global expansion of our business.We derive a substantial portion of our revenues, and have significant operations, outside the United States. Our international operations include theNetherlands-based accommodation reservation service Booking.com, the Asia-based12 accommodation reservation service agoda.com, the U.K.-based rental car reservation service Rentalcars.com and, to a lesser extent, KAYAK's internationalmeta-search services and OpenTable's international restaurant reservation business. Our international OTC operations have achieved significant year-over-year growth in their gross bookings (an operating and statistical metric referring to the total dollar value, generally inclusive of all taxes and fees, of all travelservices booked by our customers, net of cancellations). This growth rate, which has contributed significantly to our growth in consolidated revenue, grossprofit and earnings, has declined, a trend we expect to continue as the absolute level of our gross bookings increases. Other factors may also slow the growthrates of our international businesses, including, for example, worldwide or regional economic conditions, any strengthening of the U.S. Dollar versus theEuro, the British Pound Sterling and other currencies, declines in ADRs, increases in cancellations, adverse changes in travel market conditions and thecompetitiveness of the market. A decline in the growth rates of our international businesses could have a negative impact on our future consolidated revenue,gross profit and earnings growth rates and, as a consequence, our stock price.Our strategy involves continued expansion in regions throughout the world. Many of these regions have different economic conditions, customs,languages, currencies, consumer expectations, levels of consumer acceptance and use of the Internet for commerce, legislation, regulatory environments(including labor laws and customs), tax laws and levels of political stability, and we are subject to associated risks typical of international businesses.International markets may have strong local competitors with an established brand and travel service provider or restaurant relationships that may makeexpansion in that market difficult and costly and take more time than anticipated. In addition, compliance with legal, regulatory or tax requirements inmultiple jurisdictions places demands on our time and resources, and we may nonetheless experience unforeseen and potentially adverse legal, regulatory ortax consequences. In some markets such as China, legal and other regulatory requirements may prohibit or limit participation by foreign businesses, such asby making foreign ownership or management of Internet or travel-related businesses illegal or difficult, or may make direct participation in those marketsuneconomic, which could make our entry into and expansion in those markets difficult or impossible, require that we work with a local partner or result inhigher operating costs. If we are unsuccessful in rapidly expanding in new and existing markets and effectively managing that expansion, our business,results of operations and financial condition could be adversely affected.Certain markets in which we operate that are in earlier stages of development have lower operating margins compared to more mature markets, whichcould have a negative impact on our overall margins as these markets increase in size over time. Also, we intend to continue to invest in addingaccommodations available for reservation on our websites, including hotels, bed and breakfasts, hostels and vacation rentals. Vacation rentals generallyconsist of, among others, properties categorized as single-unit and multi-unit villas, apartments, "aparthotels" (which are apartments with a front desk andcleaning service) and chalets and are generally self-catered (i.e., include a kitchen), directly bookable properties. Many of the newer accommodations we addto our travel reservation services, especially in highly penetrated markets, may have fewer rooms or higher credit risk and may appeal to a smaller subset ofconsumers (e.g., hostels and bed and breakfasts). Because a vacation rental is typically either a single unit or a small collection of independent units, vacationrental properties represent more limited booking opportunities than non-vacation rental properties, which generally have more units to rent per property. Ourvacation rental accommodations in general may be subject to increased seasonality due to local tourism seasons, weather or other factors. Our vacation rentalaccommodation business may also experience lower profit margins due to certain additional costs related to offering these accommodations on our websites.As we increase our vacation rental accommodation business, these different characteristics could negatively impact our profit margins; and, to the extentthese properties represent an increasing percentage of the properties added to our websites, we expect that our gross bookings growth rate and propertygrowth rate will continue to diverge over time (since each such property has fewer booking opportunities). As a result of the foregoing, as the percentage ofvacation rental properties increases, the number of reservations per property will likely continue to decrease.In addition, as our vacation rental reservation business grows, we may incur increasing numbers of complaints related to non-existent properties orproperties that are significantly different than as described in the listing, as well as claims of liability based on events occurring at such properties such asrobbery, injury, death and other similar events. Such complaints or claims could result in negative publicity and increased costs, which could adversely affectour business and results of operations. Further, the regulatory environment related to vacation rentals is evolving and laws, regulations or propertyassociation rules could impose restrictions or burdens on vacation rental property owners that limit or negatively affect their ability to rent their properties.Some jurisdictions have adopted or are considering statutes or ordinances that prohibit owners and managers from renting certain properties for fewer than astated number of consecutive days or for more than an aggregate total number of days per year. Such regulations could negatively impact the growth of ourvacation rental reservation business.We believe that the increase in the number of accommodation providers that participate on our websites, and the corresponding access toaccommodation room nights, has been a key driver of the growth of our accommodation reservation business. The growth in our accommodation bookingstypically makes us an attractive source of consumer demand for our accommodation providers. However, accommodation providers may wish to limit theamount of business that flows through a13 single distribution channel. As a result, we may experience constraints on the number of accommodation room nights available to us, which could negativelyimpact our growth rate and results of operations.The number of our employees worldwide has grown from less than 700 in the first quarter of 2007 to approximately 18,500 as of December 31, 2016,which growth is mostly comprised of hires by our international operations. We may not be able to hire, train, retain, motivate and manage required personnel,which may limit our growth, damage our reputation, negatively affect our financial performance, and otherwise harm our business. In addition, expansionincreases the complexity of our business and places additional strain on our management, operations, technical performance, financial resources and internalfinancial control and reporting functions. Our current and planned personnel, systems, procedures and controls may not be adequate to support andeffectively manage this growth and our future operations, especially as we employ personnel in multiple geographic locations around the world.We rely on performance and brand advertising channels to generate a significant amount of traffic to our websites and grow our business.We believe that maintaining and strengthening our brands are important aspects of our efforts to attract and retain customers. We have investedconsiderable money and resources in the establishment and maintenance of our brands, and we will continue to invest resources in brand advertising,marketing and other brand building efforts to preserve and enhance consumer awareness of our brands. In addition, effective performance advertising hasbeen an important factor in our growth, and we believe it will continue to be important to our future success. As our competitors spend increasingly more onadvertising, we are required to spend more in order to maintain our brand recognition and, in the case of performance advertising, to maintain and grow trafficto our websites. We may not be able to successfully maintain or enhance consumer awareness and acceptance of our brands, and, even if we are successful inour branding efforts, such efforts may not be cost-effective. If we are unable to maintain or enhance consumer awareness and acceptance of our brands in acost-effective manner, our business, market share and results of operations would be materially adversely affected.Our online performance advertising efficiency, expressed as performance advertising expense as a percentage of gross profit, is impacted by anumber of factors that are subject to variability and that are, in some cases, outside of our control, including ADRs, costs per click, cancellation rates, foreignexchange rates, our ability to convert paid traffic to booking customers and the extent to which consumers come directly to our websites or mobile apps forbookings. For example, competition for desired rankings in search results and/or a decline in ad clicks by consumers could increase our costs-per-click andreduce our performance advertising efficiency. We use third-party websites, including online search engines (primarily Google), meta-search and travelresearch services and affiliate marketing as primary means of generating traffic to our websites. Our performance advertising expense has increasedsignificantly and our performance advertising efficiency has declined in recent years, a trend we expect to continue. In 2016, performance advertisingefficiency declined compared to the prior year, mainly due to growth of paid traffic channels, lower ROIs and timing of booking versus travel resulting fromaccelerating gross bookings growth during the year. Any reduction in our performance advertising efficiency could have an adverse effect on our businessand results of operations, whether through reduced gross profit or gross profit growth or through advertising expenses increasing faster than gross profit andthereby reducing margins and earnings growth.We believe that a number of factors could cause consumers to increase their shopping activity before making a travel purchase. Increased shoppingactivity reduces our performance advertising efficiency and effectiveness because traffic becomes less likely to result in a purchase on our website, and suchtraffic is more likely to be obtained through paid performance advertising channels than through free direct channels. Further, consumers may favor travelservices offered by search or meta-search companies over OTCs, which could reduce traffic to our travel reservation websites, increase consumer awareness ofour competitors' brands and websites, increase our advertising and other customer acquisition costs and adversely affect our business, margins and results ofoperations. To the extent any such increased shopping behavior leads to growth in our KAYAK meta-search business, such growth may not result in sufficientincreases in revenues from our KAYAK meta-search business to offset any related decrease in gross profit or increase in advertising and other customeracquisition costs experienced by our OTC brands.Our business could be negatively affected by changes in Internet search engine algorithms and dynamics or traffic-generating arrangements.We use Google to generate a significant portion of the traffic to our websites, and, to a lesser extent, we use other search engines and meta-searchwebsites to generate traffic to our websites, principally through pay-per-click advertising campaigns. The pricing and operating dynamics on these searchengines can experience rapid change commercially, technically and competitively. For example, Google frequently updates and changes the logic whichdetermines the placement and display of results of a consumer's search, such that the placement of links to our websites can be negatively affected and ourcosts to improve or maintain our placement in search results can increase. Changes by Google in how it presents travel14 search results,including its promotion of its travel meta-search services, or the manner in which it conducts the auction for placement among search resultsmay be competitively disadvantageous to us and may impact our ability to efficiently generate traffic to our websites, which in turn would have an adverseeffect on our business, market share and results of operations.In addition, we purchase website traffic from a number of other sources, including some operated by our competitors, in the form of pay-per-clickarrangements that can be terminated with little or no notice. If one or more of such arrangements is terminated, our business, market share and results ofoperations could be adversely affected. Lastly, we rely on various third-party distribution channels (i.e., marketing affiliates) to distribute accommodation,rental car and airline ticket reservations. Should one or more of such third parties cease distribution of reservations made through us, or suffer deterioration inits search engine ranking, due to changes in search engine algorithms or otherwise, our business, market share and results of operations could be negativelyaffected.Consumer adoption and use of mobile devices creates new challenges and may enable device companies such as Apple to compete directly with us.Widespread adoption of mobile devices, such as the iPhone, Android-enabled smartphones and tablets such as the iPad, coupled with the webbrowsing functionality and development of thousands of useful apps available on these devices, is driving substantial online traffic and commerce to mobileplatforms. We have experienced a significant shift of business, both direct and indirect, to mobile platforms and our advertising partners are also seeing arapid shift of traffic to mobile platforms. Our major competitors and certain new market entrants are offering mobile apps for travel products and otherfunctionality, including proprietary last-minute discounts for accommodation reservations. Advertising and distribution opportunities may be more limitedon mobile devices given their smaller screen sizes. The gross profit earned on a mobile transaction may be less than a typical desktop transaction due todifferent consumer purchasing patterns. For example, accommodation reservations made on a mobile device typically are for shorter lengths of stay and arenot made as far in advance. Further, given the device sizes and technical limitations of tablets and smartphones, mobile consumers may not be willing todownload multiple apps from multiple companies providing a similar service and instead prefer to use one or a limited number of apps for their mobile traveland restaurant research and reservation activity. As a result, the consumer experience with mobile apps as well as brand recognition and loyalty are likely tobecome increasingly important. Our mobile offerings have received generally strong reviews and are driving a material and increasing share of our business.We believe that mobile bookings present an opportunity for growth and are necessary to maintain and grow our business as consumers increasingly turn tomobile devices instead of a personal computer. As a result, it is increasingly important for us to develop and maintain effective mobile apps and websitesoptimized for mobile devices to provide consumers with an appealing, easy-to-use mobile experience. If we are unable to continue to rapidly innovate andcreate new, user-friendly and differentiated mobile offerings and efficiently and effectively advertise and distribute on these platforms, or if our mobileofferings are not used by consumers, we could lose market share to existing competitors or new entrants and our business, future growth and results ofoperations could be adversely affected.Google's Android operating system is the leading smartphone operating system in the world. As a result, Google could leverage its Androidoperating system to give its travel services a competitive advantage, either technically or with prominence on its Google Play app store or within its mobilesearch results. Further, Google is the leading Internet search service and has leveraged its search popularity to promote its travel meta-search services.Similarly, Apple, the producer of, among other things, the iPhone and iPad, obtained a patent for "iTravel," a mobile app that would allow a traveler to checkin for a travel reservation. In addition, Apple's iPhone operating system includes "Wallet" (formerly known as "Passbook"), a virtual wallet app that holdstickets, boarding passes, coupons and gift cards, and, along with iTravel, may be indicative of Apple's intent to enter the travel reservations business in somecapacity. Apple has substantial market share in the smartphone category and controls integration of offerings, including travel services, into its mobileoperating system. Apple also has more experience producing and developing mobile apps and has access to greater resources than we have. Apple may use orexpand iTravel, Wallet, Siri (Apple's voice recognition "concierge" service), Apple Pay (Apple's mobile payment system) or another mobile app orfunctionality as a means of entering the travel reservations marketplace. To the extent Apple or Google use their mobile operating systems, app distributionchannels or, in the case of Google, search services, to favor their own travel service offerings, our business and results of operations could be harmed.We may not be able to keep up with rapid technological changes.The markets in which we compete are characterized by rapidly changing technology, evolving industry standards, consolidation, frequent newservice announcements, introductions and enhancements and changing consumer demands. We may not be able to keep up with these rapid changes. Inaddition, these market characteristics are heightened by the progress of technology adoption in various markets, including the continuing adoption of theInternet and online commerce in certain geographies and the emergence and growth of the use of smartphones and tablets for mobile e-commercetransactions, including through the increasing use of mobile apps. As a result, our future success will depend on our ability to adapt to15 rapidly changing technologies, to adapt our services to evolving industry standards and to continually innovate and improve the performance, features andreliability of our services in response to competitive service offerings and the evolving demands of the marketplace. In particular, we believe that it isincreasingly important for us to effectively offer our services through mobile apps and mobile-optimized websites on smartphones and tablets. Any failure byus to successfully develop and achieve customer adoption of our mobile apps and mobile-optimized websites would likely have a material and adverse effecton our growth, market share, business and results of operations. Further, to the extent mobile devices enable users to block advertising content on theirdevices, our advertising revenue and our ability to market our brands and acquire new customers may be negatively affected. We believe that ease-of-use,comprehensive functionality and the look and feel of our mobile apps and mobile-optimized websites increasingly will be competitively critical asconsumers obtain more of their travel and restaurant services through mobile devices. As a result, we intend to continue to spend significant resourcesmaintaining, developing and enhancing our websites and mobile platforms, including our mobile-optimized websites and mobile apps, and othertechnologies.In addition, the widespread adoption of new Internet, networking or telecommunications technologies or other technological changes (includingnew devices and services, such as Amazon's Echo and Alexa and Google Home, and developing technologies, such as artificial intelligence and chatbottechnologies) could require us to incur substantial expenditures to modify or adapt our services or infrastructure to those new technologies, which couldadversely affect our results of operations or financial condition. For example, KAYAK generates revenues, in part, by allowing consumers to compare searchresults that appear in additional "pop-under" windows. Changes in browser functionality, such as changes that either block or otherwise limit the use of "pop-under" windows, at times have had a negative impact on our revenues. Any failure to implement or adapt to new technologies in a timely manner or at allcould adversely affect our ability to compete, increase our customer acquisition costs or otherwise adversely affect our business, and therefore adverselyaffect our brand, market share and results of operations.Our processing, storage, use and disclosure of personal data exposes us to risks of internal or external security breaches and could give rise toliabilities.The security of data when engaging in electronic commerce is essential to maintaining consumer and travel service provider confidence in ourservices. Any security breach whether instigated internally or externally on our systems or other Internet-based systems could significantly harm ourreputation and therefore our business, brand, market share and results of operations. We currently require consumers who use certain of our services toguarantee their offers with their credit card. We require user names and passwords in order to access our information technology systems. We also useencryption and authentication technologies to secure the transmission and storage of data and prevent unauthorized access to our data or accounts. It ispossible that computer circumvention capabilities, new discoveries or advances or other developments, including our own acts or omissions, could result in acompromise or breach of consumer data. For example, third parties may attempt to fraudulently induce employees or customers to disclose user names,passwords or other sensitive information ("phishing"), which may in turn be used to access our information technology systems or to defraud our customers.We have experienced targeted and organized phishing attacks and may experience more in the future. Our efforts to protect information from unauthorizedaccess may be unsuccessful or may result in the rejection of legitimate attempts to book reservations through our services, any of which could result in lostbusiness and materially adversely affect our business, reputation and results of operations.Our existing security measures may not be successful in preventing security breaches. A party (whether internal, external, an affiliate or unrelatedthird party) that is able to circumvent our security systems could steal consumer information or transaction data or other proprietary information. In the lastfew years, several major companies, including Yahoo!, Sony, Home Depot, JPMorgan, Target, Zappos, Apple, AOL, LinkedIn and Google experienced high-profile security breaches that exposed their customers' and/or employees' personal information. We expend significant resources to protect against securitybreaches, and we may need to increase our security-related expenditures to maintain or increase our systems' security or to address problems caused andliabilities incurred by breaches. These issues are likely to become more difficult to manage as we expand the number of places where we operate and as thetools and techniques used in such attacks become more advanced. As experienced by Sony, security breaches could result in severe damage to ourinformation technology infrastructure, including damage that could impair our ability to offer our services or the ability of consumers to make reservations orconduct searches through our services, as well as loss of customer, financial or other data that could materially and adversely affect our ability to conduct ourbusiness, satisfy our commercial obligations or meet our public reporting requirements in a timely fashion or at all. Security breaches could also result innegative publicity, damage our reputation, expose us to risk of loss or litigation and possible liability, subject us to regulatory penalties and sanctions, orcause consumers to lose confidence in our security and choose to use the services of our competitors, any of which would have a negative effect on the valueof our brand, our market share and our results of operations. Our insurance policies carry low coverage limits, and would likely not be adequate to reimburseus for all losses caused by security breaches.16 We also face risks associated with security breaches affecting third parties conducting business over the Internet. Consumers generally are concernedwith security and privacy on the Internet, and any publicized security problems could negatively affect consumers' willingness to provide private informationor effect commercial transactions on the Internet generally, including through our services. Some of our business is conducted with third-party marketingaffiliates, which may generate travel reservations through our infrastructure or through other systems. Additionally, consumers using our services could beaffected by security breaches at third parties such as travel service providers, payroll providers, health plan providers, payment processors or globaldistribution systems ("GDSs") upon which we rely. A security breach at any such third-party marketing affiliate, travel service provider, GDS or other thirdparty on which we rely could be perceived by consumers as a security breach of our systems and in any event could result in negative publicity, damage ourreputation, expose us to risk of loss or litigation and possible liability and subject us to regulatory penalties and sanctions. In addition, such third parties maynot comply with applicable disclosure requirements, which could expose us to liability.In our processing of travel transactions, we receive and store a large volume of personally identifiable data. This data is increasingly subject tolegislation and regulations in numerous jurisdictions around the world, such as the European Union's Data Protection Directive and variations andimplementations of that directive in the member states of the European Union. In addition, in April 2016 the European Union adopted a new General DataProtection Regulation designed to unify data protection within the European Union under a single law, which may result in significantly greater complianceburdens and costs for companies with users and operations in the European Union. Under the General Data Protection Regulation, fines of up to 20 millionEuros or up to 4% of the annual global turnover of the infringer, whichever is greater, could be imposed. This government action is typically intended toprotect the privacy of personal data that is collected, processed and transmitted in or from the governing jurisdiction. In many cases, these laws apply notonly to third-party transactions, but also to transfers of information between us and our subsidiaries, including employee information. The new General DataProtection Regulation is not expected to apply to us until May 2018. In February 2016, E.U. and U.S. authorities announced that they had reached agreementon a new data transfer framework, called the E.U.-U.S. Privacy Shield, which was formally adopted by the European Commission on July 12, 2016. TheEuropean Union and the United States are implementing the new framework, but it is expected to be subject to legal challenge. These laws and theirinterpretations continue to develop and may be inconsistent from jurisdiction to jurisdiction. Non-compliance with these laws could result in penalties orsignificant legal liability. We could be adversely affected if legislation or regulations are expanded to require changes in our business practices or ifgoverning jurisdictions interpret or implement their legislation or regulations in ways that negatively affect our business, results of operations or financialcondition.We are also subject to payment card association rules and obligations under our contracts with payment card processors. Under these rules andobligations, if information is compromised, we could be liable to payment card issuers for associated expenses and penalties. In addition, if we fail to followpayment card industry security standards, even if no customer information is compromised, we could incur significant fines or experience a significantincrease in payment card transaction costs.System capacity constraints, system failures or "denial-of-service" or other attacks could harm our business.We have experienced rapid growth in consumer traffic to our websites and through our mobile apps, the number of accommodations on our extranetsand the geographic breadth of our operations. If our systems cannot be expanded to cope with increased demand or fail to perform, we could experienceunanticipated disruptions in service, slower response times, decreased customer service and customer satisfaction and delays in the introduction of newservices, any of which could impair our reputation, damage our brands and materially and adversely affect our results of operations. Further, as an onlinebusiness, we are dependent on the Internet and maintaining connectivity between ourselves and consumers, sources of Internet traffic, such as Google, andour travel service providers. As consumers increasingly turn to mobile devices, we also become dependent on consumers' access to the Internet throughmobile carriers and their systems. Disruptions in Internet access, such as the denial of service attack against Dyn in October 2016 that resulted in a serviceoutage for a number of major Internet companies, whether generally, in a specific market or otherwise, especially if widespread or prolonged, could materiallyadversely affect our business and results of operations. While we do maintain redundant systems and hosting services, it is possible that we could experiencean interruption in our business, and we do not carry business interruption insurance sufficient to compensate us for all losses that may occur.Our computer hardware for operating our services is currently located at hosting facilities around the world. These systems and operations arevulnerable to damage or interruption from human error, floods, fires, power loss, telecommunication failures and similar events. They are also subject tobreak-ins, sabotage, intentional acts of vandalism, terrorism and similar misconduct. Despite any precautions we may take, the occurrence of any disruptionof service due to any such misconduct, natural disaster or other unanticipated problems at such facilities, or the failure by such facilities to provide ourrequired data communications capacity could result in lengthy interruptions or delays in our services. Any system failure17 that causes an interruption or delay in service could impair our reputation, damage our brands or result in consumers choosing to use a competitive service,any of which could have a material adverse effect on our business and results of operations.Our existing security measures may not be successful in preventing attacks on our systems, and any such attack could cause significant interruptionsin our operations. For instance, from time to time, we have experienced "denial-of-service" type attacks on our systems that have made portions of ourwebsites slow or unavailable for periods of time. There are numerous other potential forms of attack, such as "phishing" (where a third party attempts toinfiltrate our systems or acquire information by posing as a legitimate inquiry or electronic communication), SQL injection (where a third party attempts toinsert malicious code into our software through data entry fields in our websites in order to gain control of the system) and attempting to use our websites as aplatform to launch a "denial-of-service" attack on another party, each of which could cause significant interruptions in our operations and potentiallyadversely affect our brand, operations and results of operations or involve us in legal or regulatory proceedings. We expend significant resources in anattempt to prepare for and mitigate the effects of any such attacks. Reductions in website availability and response time could cause loss of substantialbusiness volumes during the occurrence of any such attack on our systems, and measures we may take to divert suspect traffic in the event of such an attackcould result in the diversion of bona fide customers. These issues are likely to become more difficult to manage as we expand the number of places where weoperate and as the tools and techniques used in such attacks become more advanced. Successful attacks could result in negative publicity, damage ourreputation and prevent consumers from booking travel services, researching travel services or making restaurant reservations through us during the attack,any of which could cause consumers to use the services of our competitors, which would have a negative effect on the value of our brands, our market share,business and results of operations.We rely on certain third-party computer systems and third-party service providers, including GDSs and computerized central reservation systems ofthe accommodation, rental car and airline industries in connection with providing some of our services. Any interruption in these third-party services andsystems or deterioration in their performance could prevent us from booking related accommodation, rental car and airline reservations and have a materialadverse effect on our business, brands and results of operations. Our agreements with some third-party service providers are terminable upon short notice andoften do not provide recourse for service interruptions. In the event our arrangement with any such third party is terminated, we may not be able to find analternative source of systems support on a timely basis or on commercially reasonable terms and, as a result, it could have a material adverse effect on ourbusiness and results of operations.We depend upon various third parties to process payments, including credit cards, for our merchant transactions around the world. In addition, werely on third parties to provide credit card numbers which we use as a payment mechanism for merchant transactions. If any such third party were wholly orpartially compromised, our cash flows could be disrupted or we may not be able to generate merchant transactions (and related revenues) until such a time asa replacement process could be put in place with a different vendor.We do not have a completely formalized or comprehensive disaster recovery plan in every geographic region in which we conduct business. In theevent of certain system failures, we may not be able to switch to back-up systems immediately and the time to full recovery could be prolonged. Like manyonline businesses, we have experienced system failures from time to time. In addition to placing increased burdens on our engineering staff, these outagescreate a significant amount of consumer questions and complaints that need to be addressed by our customer support personnel. Any unscheduledinterruption in our service could result in an immediate loss of revenues that could be substantial, increase customer service costs, harm our reputation andresult in some consumers switching to our competitors. If we experience frequent or persistent system failures, our reputation and brand could be permanentlyand significantly harmed. We have taken and continue to take steps to increase the reliability and redundancy of our systems. These steps are expensive, mayreduce our margins and may not be successful in reducing the frequency or duration of unscheduled downtime.We use both internally developed systems and third-party systems to operate our services, including transaction processing, order management andfinancial systems. If the number of consumers using our services increases substantially, or if critical third-party systems stop operating as designed, we willneed to significantly expand and upgrade our technology, transaction processing systems, financial and accounting systems and other infrastructure. We maynot be able to upgrade our systems and infrastructure to accommodate such conditions in a timely manner, and, depending on the third-party systemsaffected, our transactional, financial and accounting systems could be impacted for a meaningful amount of time before upgrade, expansion or repair.We may have exposure to additional tax liabilities.As an international business providing reservation and advertising services around the world, we are subject to income taxes and non-income-basedtaxes in the United States and various international jurisdictions. Due to economic and political conditions, tax rates and tax regimes in various jurisdictionsmay be subject to significant change. Our future effective tax rates18 could be affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets or changes intax laws or their interpretation. If our effective tax rates were to increase, our results of operations, financial condition and cash flows would be adverselyaffected.Although we believe that our tax filing positions are reasonable and comply with applicable law, the final determination of tax audits or tax disputesmay be different from what is reflected in our historical income tax provisions and accruals. To date, we have been audited in many taxing jurisdictions withno significant impact on our results of operations, financial condition or cash flows. If future audits find that additional taxes are due, we may be subject toincremental tax liabilities, possibly including interest and penalties, which could have a material adverse effect on our results of operations, financialcondition and cash flows.For example, French tax authorities recently concluded an audit that started in 2013 of the tax years 2003 through 2012. The French authorities areasserting that Booking.com has a permanent establishment in France and are seeking to recover what they claim are unpaid income taxes and value-addedtaxes. In December 2015, the French tax authorities issued assessments for approximately 356 million Euros, the majority of which represents penalties andinterest. We believe that Booking.com has been, and continues to be, in compliance with French tax law, and we intend to contest the assessments. If we areunable to resolve the matter with the French authorities, we would expect to challenge the assessments in the French courts. We may be required to pay,upfront, the full amount or a significant part of any such assessments, though any such payment would not constitute an admission by us that we owe thetaxes. At the end of 2016, the French authorities announced their intent to also audit the tax years 2013 to 2015, which could result in additionalassessments.Italian tax authorities have initiated a process to determine whether we should be subject to additional tax obligations in Italy. Italian tax authoritiesmay determine that we owe additional taxes, and may also assess penalties and interest. We believe that we have been, and continue to be, in compliancewith Italian tax law. In general, governments in the United States and Europe are increasingly focused on ways to increase tax revenues, which hascontributed to an increase in audit activity and harsher stances taken by tax authorities. Any such additional taxes or other assessments may be in excess ofour current tax provisions or may require us to modify our business practices in order to reduce our exposure to additional taxes going forward, any of whichcould have a material adverse effect on our business, results of operations and financial condition.As of December 31, 2016, we held approximately $12.6 billion of cash, cash equivalents, short-term investments and long-term investments outsideof the United States. We currently intend to use our cash held outside the United States to reinvest in our international operations. If that intention changesand we decide to repatriate that cash to the United States, whether due to cash needs in the United States or otherwise, we would incur related U.S. income taxexpense, and we would only make income tax payments when we repatriate the cash. We would pay only U.S. federal alternative minimum tax and certainU.S. state income taxes as long as we have net operating loss carryforwards available to offset our U.S. taxable income. If our foreign earnings wererepatriated, this could result in us being subject to a cash income tax liability on the earnings of our U.S. businesses sooner than would otherwise have beenthe case. After our net operating loss carryforwards have been fully utilized, foreign tax credits associated with the repatriation of international cash may beused to reduce U.S. federal taxes on the repatriation.Various proposals have been put forward to reform U.S. corporate income tax law, including proposals that would significantly impact how and atwhat rates U.S. multinationals are taxed on international earnings. These proposals range from changing the U.S. worldwide tax system to a territorial taxsystem on the one hand to eliminating the current tax deferral system altogether on the other, introducing a border-adjustment tax that exempts exports buttaxes imports, and permitting the expensing of the full cost of certain tangible and intangible property in the year of investment, but limiting interestdeductions to interest income with any excess deduction being carried forward to the following year. Other tax reform proposals advanced include limitinginterest deductions in thin capitalization circumstances or eliminating all interest deductions, eliminating all business tax expenditures includingdeductions, exemptions and most credits (excluding R&D credits), changing the rules on the use of net operating losses, potential reduction of U.S. corporatetax rates and allowing international earnings accumulated under the current system to be repatriated to the U.S. at a favorable tax rate. We cannot determinewhether some or all of these or other proposals will be enacted into law or what, if any, changes may be made to such proposals prior to being enacted intolaw. If U.S. tax laws change in a manner that increases our tax obligations, our financial position and results of operations could be adversely impacted.Additionally, in October 2015, the Organisation for Economic Co-operation and Development ("OECD") issued "final reports" in connection with its"base erosion and profit shifting" ("BEPS") project. The OECD, with the support of the G20, initiated this project in 2013 in response to concerns thatinternational tax standards have not kept pace with changes in global business practices and that changes are needed to international tax laws to addresssituations where multinational businesses may pay little or no tax in certain jurisdictions by shifting profits away from jurisdictions where the activitiescreating those19 profits may take place. The final reports were endorsed by the G20 leaders in November 2015. The final reports propose 15 actions the OECD determined areneeded to address base erosion and profit shifting, including: (a) enhancing transparency through the sharing of tax information between countries; (b)prescribing standardized country-by-country reporting and other documentation requirements aimed at identifying where profits, tax and economic activitiesoccur; (c) preventing harmful tax practices including the use of preferential tax regimes; (d) modernizing the OECD's transfer pricing rules related tointangibles; (e) changing the definition of permanent establishment to prevent artificial avoidance of tax nexus; and (f) limiting tax base erosion throughinterest deductions and other financial payments. The measures have resulted in the development of a multilateral instrument to incorporate and facilitatechanges to tax treaties. On January 28, 2016, the European Commission unveiled a new package of proposals aimed at providing a framework for fairertaxation and to provide a coordinated European Union response to combating corporate tax avoidance. Following agreement among the European Unionmember states on the final content of the package, the European Council formally adopted an Anti-Tax Avoidance Directive on July 12, 2016. The Directiveis aimed at preventing aggressive tax planning, increasing tax transparency and creating a fairer tax environment for all businesses in the European Union.We expect many countries to change their tax laws in response to these developments, and several countries have already changed or proposed changes totheir tax laws in response to the final BEPS reports and/or the developments in the European Union. Any changes to international tax laws, including newdefinitions of permanent establishment or changes affecting the benefits of preferential tax regimes such as the Dutch "Innovation Box Tax" (discussedbelow), could impact the tax treatment of our foreign earnings and adversely impact our effective tax rate. Further, changes to tax laws and additionalreporting requirements could increase the complexity, burden and cost of compliance. Due to the large and expanding scale of our international businessactivities, any changes in U.S. or international taxation of our activities may increase our worldwide effective tax rate, increase the complexity and costsassociated with tax compliance (especially if changes are implemented or interpreted inconsistently across tax jurisdictions) and adversely affect ourfinancial position and results of operations.We are also subject to non-income-based taxes, such as value-added, payroll, sales, use, net worth, property and goods and services taxes, in theUnited States and various international jurisdictions, as well as the potential for travel transaction taxes in the United States as discussed below and in Note14 to our Consolidated Financial Statements. From time to time, we are under audit by tax authorities with respect to these non-income-based taxes and mayhave exposure to additional non-income-based tax liabilities.We may not be able to maintain our "Innovation Box Tax" benefit.The Netherlands corporate income tax law provides that income generated from qualifying innovative activities is taxed at the rate of 5%("Innovation Box Tax") rather than the Dutch statutory rate of 25%. A portion of Booking.com's earnings currently qualifies for Innovation Box Taxtreatment. In the year ended December 31, 2016, the Innovation Box Tax benefit reduced our consolidated income tax expense by approximately $324.6million.In order to be eligible for Innovation Box Tax treatment, Booking.com must, among other things, apply for and obtain a research and development("R&D") certificate from a Dutch governmental agency every six months confirming that the activities that Booking.com intends to be engaged in over thesubsequent six-month period are "innovative." The R&D certificate is current but should Booking.com fail to secure such a certificate in any future period -for example, because the governmental agency does not view Booking.com's new or anticipated activities as innovative - or should this agency determinethat the activities contemplated to be performed in a prior period were not performed as contemplated or did not comply with the agency's requirements,Booking.com may lose its certificate and, as a result, the Innovation Box Tax benefit may be reduced or eliminated. Booking.com intends to apply forcontinued Innovation Box Tax treatment for future periods. However, Booking.com's application may not be accepted, or, if accepted, the amount ofqualifying earnings may be reduced.In addition, tax laws may change resulting in a reduction or elimination of the tax benefit. As discussed above, the OECD's action plan involves, inpart, evaluation of preferential tax regimes such as the Innovation Box Tax. The European Union Council of Economics and Finance Ministers ("ECOFIN")has endorsed changes to limit member states' existing innovation and patent box tax regimes providing benefits related to profits derived from intangibleassets such as intellectual property. The OECD's October 2015 final reports recommend that intellectual property qualifying for such tax regimes generally belimited to patents and other intellectual property assets that are functionally equivalent to patents (such as copyrighted software) if those other assets are bothlegally protected and subject to similar approval and registration processes as apply to patents. ECOFIN has endorsed the OECD's modified nexus approachand the European Union Code of Conduct Group will monitor legislative processes in 2016 necessary for European Union member states to change theirexisting "IP box" regimes to conform to the modified nexus approach, which requires full implementation in member states no later than July 2021. On May19, 2016, the Dutch government launched a public Internet consultation process on proposed legislative changes to the Dutch Innovation Box Tax regimebased on the above-mentioned recommendations made in the OECD's final BEPS report and recent evaluations on the working of the Dutch Innovation BoxTax. The proposed legislative changes were20 introduced in the Dutch Parliament in September 2016 and approved in December 2016. The new innovation tax rules took effect on January 1, 2017, butalso include transition rules. We do not expect the new legislation to have a significant impact on Booking.com's eligibility for the Innovation Box Tax.The loss of the Innovation Box Tax benefit (or any material portion thereof), whether due to a change in tax law or a determination by the Dutchgovernment that Booking.com's activities are not "innovative" or for any other reason, would substantially increase our effective tax rate and adverselyimpact our results of operations.Adverse application of U.S. state and local tax laws could have an adverse effect on our business and results of operations.A number of jurisdictions in the United States have initiated lawsuits against online travel companies, including us, related to, among other things,the payment of travel transaction taxes (e.g., hotel occupancy taxes, excise taxes, sales taxes, etc.). In addition, a number of U.S. states, counties andmunicipalities have initiated audit proceedings, issued proposed tax assessments or started inquiries relating to the payment of travel transaction taxes.Additional state and local jurisdictions may assert that we are subject to, among other things, travel transaction taxes and could seek to collect such taxes,either retroactively or prospectively, or both.In many of the judicial and other proceedings initiated to date, the taxing jurisdictions seek not only historical taxes that are claimed to be owed onour gross profit, but also, among other things, interest, penalties, punitive damages and/or attorneys' fees and costs. To date, many of the taxing jurisdictionsin which we facilitate travel reservations have not asserted that taxes are due and payable on our travel services. With respect to taxing jurisdictions thathave not initiated proceedings to date, it is possible that they will do so in the future or that they will seek to amend their tax statutes and seek to collecttaxes from us only on a prospective basis.In connection with some travel transaction tax audits and assessments, we may be required to pay any assessed taxes, which amounts may besubstantial, prior to being allowed to contest the assessments and the applicability of the laws in judicial proceedings. Payment of these amounts, if any, isnot an admission that we believe that we are subject to such taxes and, even if we make such payments, we intend to continue to assert our position that weshould not be subject to such taxes.Litigation is subject to uncertainty and there could be adverse developments in these pending or future cases and proceedings. Adverse taxdecisions could have a material adverse effect on our business, margins and results of operations. An unfavorable outcome or settlement of pending litigationmay encourage the commencement of additional litigation, audit proceedings or other regulatory inquiries. In addition, an unfavorable outcome orsettlement of these actions or proceedings could result in substantial liabilities for past and/or future bookings, including, among other things, interest,penalties, punitive damages and/or attorneys' fees and costs.We are dependent on providers of accommodations, rental cars and airline tickets and on restaurants.We rely on providers of accommodations, rental cars and airline tickets and on restaurants to make their services available to consumers through us.Our arrangements with travel service providers generally do not require them to make available any specific quantity of accommodation reservations, rentalcars or airline tickets, or to make accommodation reservations, rental cars or airline tickets available in any geographic area, for any particular route or at anyparticular price. Similarly, our arrangements with restaurants generally do not require them to provide all of their available tables and reservations tocustomers through us. During the course of our business, we are in continuous dialogue with our major travel service providers about the nature and extent oftheir participation in our services. A significant reduction on the part of any of our major travel service providers or providers that are particularly popularwith consumers in their participation in our services for a sustained period of time or their complete withdrawal could have a material adverse effect on ourbusiness, market share and results of operations. To the extent any of those major or popular travel service providers ceased to participate in our services infavor of one of our competitors' systems or decided to require consumers to purchase services directly from them, our business, market share and results ofoperations could be harmed. During periods of higher occupancy rates, accommodation providers may decrease their distribution of accommodationreservations through third-party intermediaries like us, in particular through our discount services such as priceline.com's Name Your Own Price® and ExpressDeals® services. Further, as consolidation among travel service providers increases, the potential adverse effect of a decision by any particular significanttravel service provider (such as a large hotel chain, airline or rental car company) to withdraw from or reduce its participation in our services also increases.To the extent restaurants limit the availability of reservations through OpenTable, consumers may not continue to use our services and/or our revenues couldbe adversely affected, especially if reservations during highly desirable times on high volume days are not made available through us.21 Further, KAYAK, a meta-search service, depends on access to information related to travel service pricing, schedules, availability and other relatedinformation from OTCs and travel service providers to attract consumers. To obtain this information, KAYAK maintains relationships with travel serviceproviders and OTCs. Many of KAYAK's agreements with travel service providers and OTCs are short-term agreements that may be terminated on 30 days'notice. To the extent OTCs or travel service providers no longer provide such information to KAYAK, KAYAK's ability to provide comprehensive travelservice information to consumers could be diminished and its brand, business and results of operations could be harmed. To the extent consumers do notview KAYAK as a reliable source of comprehensive travel service information, fewer consumers would likely visit its websites, which would also likely havea negative impact on KAYAK's advertising revenue and results of operations. In addition, if travel service providers or OTCs choose not to advertise withKAYAK or choose to reduce or eliminate the fees paid to KAYAK for referrals from query results, KAYAK's business and results of operations could beadversely affected.We rely on the performance of highly skilled personnel; and, if we are unable to retain or motivate key personnel or hire, retain and motivatequalified personnel, our business would be harmed.Our performance is largely dependent on the talents and efforts of highly skilled individuals. Our future success depends on our continuing abilityto identify, hire, develop, motivate and retain highly skilled personnel for all areas of our organization. In particular, the contributions of key seniormanagement in the United States, Europe and Asia are critical to the overall management of our business. We may not be able to retain the services of anymembers of our senior management or other key employees, the loss of whom could harm our business and competitive position.In addition, competition for well-qualified employees in all aspects of our business, including software engineers, mobile communication talent andother technology professionals, is intense both in the United States and abroad. Our international success in particular has led to increased efforts by ourcompetitors and others to hire our international employees. Our continued ability to compete effectively depends on our ability to attract new employees andto retain and motivate existing employees. If we do not succeed in attracting well-qualified employees or retaining and motivating existing employees, ourbusiness, competitive position and results of operations would be adversely affected. We do not maintain any key person life insurance policies.As the size of our business grows, we may become increasingly subject to the scrutiny of anti-trust and competition regulators.The online travel industry has become the subject of investigations by various national competition authorities ("NCAs"), particularly in Europe.We are or have been involved in investigations predominately related to whether Booking.com's contractual parity arrangements with accommodationproviders, sometimes also referred to as "most favored nation" or "MFN" provisions, are anti-competitive because they require accommodation providers toprovide Booking.com with room rates that are at least as low as those offered to other OTCs or through the accommodation provider's website.Investigations into Booking.com's parity provisions were initiated in 2013 and 2014 by NCAs in France, Germany, Italy, Austria, Sweden, Irelandand Switzerland. A number of other NCAs have also looked at these issues. On April 21, 2015, the French, Italian and Swedish NCAs, working in closecooperation with the European Commission, announced that they had accepted "commitments" offered by Booking.com to resolve and close theinvestigations in France, Italy and Sweden. Under the commitments, Booking.com replaced its existing price parity agreements with accommodationproviders with "narrow" price parity agreements. Under a "narrow" price parity agreement, subject to certain exceptions, an accommodation provider is stillrequired to offer the same or better rates on Booking.com as it offers to a consumer directly online, but it is no longer required to offer the same or better rateson Booking.com as it offers to other OTCs. The commitments also allow an accommodation provider to, among other things, offer different terms andconditions (e.g., free WiFi) and availability to consumers that book with online travel companies that offer lower rates of commission or other benefits, offerlower rates to consumers that book through offline channels and continue to discount through, among other things, accommodation loyalty programs, aslong as those rates are not published or marketed online. The commitments apply to accommodations in France, Italy and Sweden and were effective on July1, 2015. The foregoing description is a summary only and is qualified in its entirety by reference to the commitments published by the NCAs on April 21,2015.On July 1, 2015, Booking.com voluntarily implemented the commitments given to the French, Italian and Swedish NCAs throughout the EuropeanEconomic Area and Switzerland. Nearly all NCAs in the European Economic Area have now closed their investigations following Booking.com'simplementation of the commitments in their jurisdictions. Booking.com has also recently resolved the concerns of the NCAs in Australia, New Zealand andGeorgia by agreeing to implement the "narrow" price parity clause in these countries. The Turkish NCA recently imposed fines on Booking.com following aninvestigation into Booking.com's "wide" parity clauses. We are in ongoing discussions with various NCAs in other countries22 regarding their concerns. We are currently unable to predict the long-term impact the implementation of these commitments will have on Booking.com'sbusiness, on investigations by other countries, or on industry practice more generally.On December 23, 2015, the German NCA issued a final decision prohibiting Booking.com's "narrow" price parity agreements with accommodationsin Germany. The German NCA did not issue a fine, but has reserved its position regarding an order for disgorgement of profits. Booking.com is appealing theGerman NCA's decision. An Italian hotel association has appealed the Italian NCA's decision to accept the commitments by Booking.com.A working group of 10 European NCAs (France, Germany, Belgium, Hungary, Ireland, Italy, the Netherlands, Czech Republic, the United Kingdomand Sweden) was established by the European Commission in December 2015 to monitor the effects of the narrow price parity clause in Europe. This workinggroup (the "ECN Working Group") issued questionnaires during 2016 to online travel agencies, including Booking.com and Expedia, meta-search sites andhotels about the narrow price parity clause. On February 17, 2017 the ECN Working Group issued a statement that it would publish its report soon and that ithad decided to keep the sector under review and re-assess the competitive situation in due course. Separately, the French NCA, which is conducting its ownreview of the effects of the narrow price parity clause, issued a report on February 9, 2017, stating that it has not ruled out the possibility of issuing anopinion at its own initiative if a change in competition requires it, and that it would continue to contribute actively to the ECN Working Group process.We are unable to predict how these appeals and the remaining investigations in other countries will ultimately be resolved, or whether further actionin Europe will be taken as a result of the working group's findings. Possible outcomes include requiring Booking.com to amend or remove its rate parityclause from its contracts with accommodation providers in those jurisdictions and/or the imposition of fines.In August 2015, French legislation known as the "Macron Law" became effective. Among other things, the Macron Law makes price parityagreements illegal, including the "narrow" price parity agreements agreed to by the French NCA in April 2015. Legislation in Austria prohibiting "narrow"price parity agreements (including the narrow parity clause) became effective on December 31, 2016. Similar legislation was approved by the Italian Senatein June 2016 but not ultimately passed, and could be introduced again in 2017. A motion to prohibit the narrow price parity clause has also been proposed inSwitzerland. It is not yet clear how the Macron Law and the Austrian legislation or the proposed Italian and Swiss legislation may affect our business in thelong term in France, Austria, Italy and Switzerland, respectively.Further, the European Commission published a communication on online platforms and the digital single market in May 2016 in which it stated thatit will engage in targeted fact-finding to investigate concerns raised in a recent public consultation regarding potential unfair terms imposed by onlineplatforms, including price parity clauses. The European Commission plans to report on its findings in the spring of 2017. We are unable to predict what, ifany, effect this inquiry will have on our business, industry practices or online commerce more generally.To the extent that regulatory authorities impose fines on us or require changes to our business practices or to those currently common to theindustry, our business, competitive position and results of operations could be materially and adversely affected. Negative publicity regarding competitioninvestigations could adversely affect our brands and therefore our market share and results of operations. Further, the Macron Law, the Italian and Austrianlaws and any similar legislation enacted by other countries, and the decision by the German NCA to prohibit "narrow" price parity agreements, could have amaterial adverse effect on our business and our results of operations, in particular if consumers use our services to shop for accommodation reservations butmake their reservations directly with an accommodation provider.Competition-related investigations, legislation or issues could also give rise to private litigation. For example, Booking.com is involved in privatelitigation in Sweden related to its "narrow" price parity provisions. We are unable to predict how this litigation will be resolved, or whether it will impactBooking.com's business in Sweden.In addition, as our business grows, we may increasingly become the target of competition investigations or be limited by anti-trust or competitionlaws. For example, our size and market share may negatively affect our ability to obtain regulatory approval of proposed acquisitions, our ability to expandinto complementary businesses or our latitude in dealing with travel service providers (such as by limiting our ability to provide discounts, rebates orincentives or to exercise contractual rights), any of which could adversely affect our business, results of operations or ability to grow and compete.23 Regulatory and legal requirements and uncertainties could harm our business.The services we offer are subject to legal regulations (including laws, ordinances, rules and other requirements and regulations) of national and localgovernments and regulatory authorities around the world, many of which are evolving and subject to the possibility of new or revised interpretations. Ourability to provide our services is and will continue to be affected by such regulations. For example, laws and proposed legislation relating to data localizationin some countries could adversely affect our ability to conduct business in those countries. The implementation of unfavorable regulations or unfavorableinterpretations of existing regulations by judicial or regulatory bodies could require us to incur significant compliance costs, cause the development of theaffected markets to become impractical and otherwise have a material adverse effect on our business and results of operations.Compliance with the laws and regulations of multiple jurisdictions increases our cost of doing business. These laws and regulations, which vary andsometimes conflict, include the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and local laws which also prohibit corrupt payments to governmentalofficials or third parties, data privacy requirements, labor relations laws, tax laws, anti-trust or competition laws, U.S., E.U. or U.N. sanctioned country orsanctioned persons mandates, and consumer protection laws. Violations of these laws and regulations could result in fines and/or criminal sanctions againstus, our officers or our employees and/or prohibitions on the conduct of our business. Any such violations could result in prohibitions on our ability to offerour services in one or more countries, could delay or prevent potential acquisitions, and could also materially damage our reputation, our brands, ourinternational expansion efforts, our ability to attract and retain employees, our business and our operating results. Even if we comply with these laws andregulations, doing business in certain jurisdictions could harm our reputation and brands, which could adversely affect our results of operations or stockprice. In addition, these restrictions may provide a competitive advantage to our competitors unless they are also subject to comparable restrictions. Oursuccess depends, in part, on our ability to anticipate these risks and manage these difficulties. We are also subject to a variety of other regulatory and legalrisks and challenges in managing an organization operating in various countries, including those related to:•regulatory changes or other government actions;•additional complexity to comply with regulations in multiple jurisdictions, as well as overlapping or inconsistent legal regimes, in particular withrespect to tax, labor, consumer protection, digital content, advertising, promotions, privacy and anti-trust laws;•our ability to repatriate funds held by our international subsidiaries to the United States at favorable tax rates;•difficulties in transferring funds from or converting currencies in certain countries; and•reduced protection for intellectual property rights in some countries.Our business has grown substantially over the last several years and continues to expand into new geographic locations. In addition, we have madeefforts and expect to make further efforts to integrate access to travel services across our various brands. These changes add complexity to legal and taxcompliance, and our increased size and operating history may increase the likelihood that we will be subject to audits by tax authorities in variousjurisdictions.We face increased risks as the level of our debt increases.We have a substantial amount of outstanding indebtedness and we may incur substantial additional indebtedness in the future, including throughpublic or private offerings of debt securities. Our outstanding indebtedness and any additional indebtedness we incur may have significant consequences,which could include:•requiring the dedication of a portion of our cash flow from operations to service our indebtedness, thereby reducing the amount of cash flowavailable for other purposes, including capital expenditures, share repurchases and acquisitions;•increased vulnerability to downturns in our business, to competitive pressures and to adverse changes in general economic and industry conditions;•decreased, or loss of, the ability to obtain additional financing on terms acceptable to us for working capital, capital expenditures, acquisitions,share repurchases or other general corporate purposes; and•decreased flexibility when planning for or reacting to changes in our business and industry.24 Our ability to make payments of principal of and interest on our indebtedness depends upon our future performance, which will be subject to generaleconomic conditions, industry cycles and financial, business and other factors affecting our consolidated results of operations and financial condition, manyof which are beyond our control. Further, we may not have access to equity or debt markets or other sources of financing, or such financing may not beavailable to us on commercially reasonable terms, to repay or refinance our debt as it comes due or, in the case of our convertible notes, upon conversion. Ifwe are unable to generate sufficient cash flow from our U.S. operations in the future to service our debt, we may be required to, among other things, repatriatefunds to the United States at substantial tax cost.Our stock price is highly volatile.The market price of our common stock is highly volatile and is likely to continue to be subject to wide fluctuations in response to factors such as thefollowing, some of which are beyond our control:•operating results that vary from the expectations of securities analysts and investors;•quarterly variations in our operating results;•changes in expectations as to our future financial performance, including financial estimates by securities analysts and investors;•worldwide economic conditions in general and in Europe in particular;•fluctuations in currency exchange rates, particularly between the U.S. Dollar and the Euro;•announcements of technological innovations or new services by us or our competitors;•changes in our capital structure;•changes in market valuations of other Internet or online service companies;•announcements by us or our competitors of price reductions, promotions, significant contracts, acquisitions, strategic partnerships, joint ventures orcapital commitments;•loss of a major travel service provider participant, such as a hotel chain, rental car company or airline, from our services;•changes in the status of our intellectual property rights;•lack of success in the expansion of our business models geographically;•announcements by third parties of significant claims or initiation of litigation proceedings against us or adverse developments in pendingproceedings;•occurrences of a significant security breach;•additions or departures of key personnel; and•trading volume fluctuations.Sales of a substantial number of shares of our common stock, including through the conversion of our convertible notes, could adversely affect themarket price of our common stock by introducing a large number of sellers to the market. Given the volatility that exists for our shares, such sales could causethe market price of our common stock to decline significantly. In addition, fluctuations in our stock price and our price-to-earnings multiple may have madeour stock attractive to momentum, hedge or day-trading investors who often shift funds into and out of stocks rapidly, exacerbating price fluctuations ineither direction, particularly when viewed on a quarterly basis.The trading prices of Internet company stocks in general, including ours, have experienced extreme price and volume fluctuations. To the extentthat the public's perception of the prospects of Internet or e-commerce companies is negative, our25 stock price could decline, regardless of our results. Other broad market and industry factors may decrease the market price of our common stock, regardless ofour operating performance. Market fluctuations, as well as general political and economic conditions, such as a recession, interest rate or currency ratefluctuations, political instability (e.g., "Brexit" or the recent coup attempt in Turkey) or a natural disaster or terrorist attack affecting a significant market forour business, such as Europe or the United States, could cause our stock price to decline. Negative market conditions could adversely affect our ability toraise additional capital or the value of our stock for purposes of acquiring other companies or businesses.We have, in the past, been a defendant in securities class action litigation. Securities class action litigation has often been brought against acompany following periods of volatility in the market price of its securities. To the extent our stock price declines or is volatile, we may in the future be thetarget of additional litigation. This additional litigation could result in substantial costs and divert management's attention and resources, either of whichcould adversely affect our business, financial condition and results of operations."Cookie" laws could negatively impact the way we do business.A "cookie" is a text file that is stored on a user's web browser by a website. Cookies are common tools used by thousands of websites, including ours,to, among other things, store or gather information (e.g., remember log-on details so a user does not have to re-enter them when revisiting a website), marketto consumers and enhance the user experience on a website. Cookies are valuable tools for websites like ours to improve the customer experience andincrease conversion on their websites.The European Union's ePrivacy Directive requires member countries to adopt regulations governing the use of "cookies" by websites servicingconsumers in the European Union. For example, a June 2012 amendment to the Dutch Telecommunications Act requires websites, including Booking.com, toprovide Dutch users with clear and comprehensive information about the storage and use of certain cookies and obtain prior consent from the user beforeplacing certain cookies on a user's web browser. To the extent any such regulations require "opt-in" consent before certain cookies can be placed on a user'sweb browser, our ability, in particular Booking.com's ability, to serve certain customers in the manner we currently do might be adversely affected and ourability to continue to improve and optimize performance on our websites might be impaired, either of which could negatively affect a consumer's experienceusing our services and our business, market share and results of operations.We face risks related to our intellectual property.We regard our intellectual property as critical to our success, and we rely on domain name, trademark, copyright and patent law, trade secretprotection and confidentiality and/or license agreements with our employees, travel service providers, partners and others to protect our proprietary rights.We have filed various applications for protection of certain aspects of our intellectual property in the United States and other jurisdictions, and we currentlyhold a number of issued patents in several jurisdictions. Further, in the future we may acquire additional patents or patent portfolios, which could requiresignificant cash expenditures. However, we may choose not to patent or otherwise register some of our intellectual property and instead rely on trade secret orother means of protecting our intellectual property. We have licensed in the past, and may license in the future, certain of our proprietary rights, such astrademarks or copyrighted material, to third parties, and these licensees may take actions that diminish the value of our proprietary rights or harm ourreputation. In addition, effective intellectual property protection may not be available in every country in which our services are made available online. Wemay be required to expend significant time and resources to prevent infringement or to enforce our intellectual property rights.We believe that our intellectual property rights, including our issued patents and pending patent applications, help to protect our business.However, we may not be able to successfully defend our intellectual property rights or they may not be sufficient to effectively protect our business.If we are not successful in protecting our intellectual property or if our intellectual property is ineffective in protecting our business, our business,brands and results of operations could be materially adversely affected.From time to time, in the ordinary course of our business, we have been subject to, and are currently subject to, legal proceedings and claims relatingto the intellectual property rights of others, and we expect that third parties will continue to assert intellectual property claims, in particular patent claims,against us, particularly as we expand the complexity and scope of our business. For example, in February 2015, IBM sued us and certain of our subsidiariesasserting that we infringed certain IBM patents and claiming damages and injunctive relief. While we believe the suit to be without merit and are contestingit, litigation is uncertain and we may not be successful. We endeavor to defend our intellectual property rights diligently, but intellectual property litigationis extremely expensive and time-consuming, and may divert managerial attention and resources from our business objectives. Successful infringement claimsagainst us could result in a significant monetary liability or26 prevent us from operating our business, or portions of our business. In addition, resolution of claims may require us to obtain licenses to use intellectualproperty rights belonging to third parties, which may be expensive to procure, or possibly to cease using those rights altogether. Any of these events couldhave a material adverse effect on our business, results of operations and financial condition.The success of our acquisition of OpenTable is subject to numerous risks and uncertainties.On July 24, 2014, we acquired OpenTable, a leading brand for booking online restaurant reservations. We believe that the online restaurantreservation business is complementary to our online travel businesses, and that both OpenTable and our travel businesses will benefit from the addition ofOpenTable to The Priceline Group. As a result of our acquisition of OpenTable, we are subject to risks associated with OpenTable's business, many of whichare the same risks that our other businesses face. Other risks include: OpenTable's ability to increase the number of restaurants and diners using its productsand services and retain existing restaurants and diners; OpenTable's ability to expand internationally; competition both to provide reservation managementservices to restaurants and to attract diners to make reservations through OpenTable's websites and apps; OpenTable's ability to effectively and efficientlymarket to new restaurants and diners; and any risks that cause people to refrain from dining at restaurants, such as economic downturns, severe weather,outbreaks of pandemic or contagious diseases, or threats of terrorist attacks.OpenTable's post-acquisition strategy was premised on significant and rapid investment in international expansion and various other growthinitiatives, resulting in near-term reduced earnings and profit margins but with the goal of achieving significantly increased revenues and profitability in thelong term. As this strategy was achieving limited progress, in the third quarter of 2016 OpenTable modified its strategy. As a result, while OpenTable intendsto continue to pursue and invest in international expansion and its other growth initiatives, it intends to do so in a more measured and deliberate manner.This change in strategy resulted in OpenTable updating its forecasted financial results to reflect (a) a material reduction in forecasted long-term financialresults from these initiatives, partially offset by (b) improved earnings and profit margins in the near term as a result of the reduced investments. As previouslydisclosed, based on the updated forecast, we estimated a significant reduction in the fair value of the OpenTable business and, for the quarter endedSeptember 30, 2016, recognized a non-deductible goodwill impairment charge of $940.7 million.Future events and changing market conditions may lead us to again re-evaluate the assumptions reflected in the updated forecast, including keyassumptions regarding OpenTable's expected growth rates and operating margins and the success and timing of its international expansion and other growthinitiatives, as well as other key assumptions with respect to matters outside of our control, such as discount rates, currency exchange rates, market EBITDAcomparables, and changes in accounting policies or practices, including proposed changes affecting measurement of goodwill and/or impairment testingmethodology. If OpenTable does not achieve the results currently expected, if its investments, in particular its investments in its international expansionefforts and other growth initiatives, are not successful, or if any of the assumptions underlying our estimate of the value of the OpenTable business, includingthose mentioned above, prove to be incorrect, we may further refine our forecast for the OpenTable business and recognize an additional goodwillimpairment and an impairment of intangible assets, which could have a material adverse effect on our results of operations.The value of our investments could decline, which could adversely affect our financial condition and results of operations.We maintain an investment portfolio of various holdings, types and maturities. These securities are predominantly classified as available-for-saleand, consequently, are recorded in our Consolidated Balance Sheets at fair value with unrealized gains or losses reported as a component of accumulatedother comprehensive income, net of tax. Our portfolio includes fixed-income securities and equity securities of publicly traded companies, the values ofwhich are subject to market price volatility. If such investments suffer market price declines, we may recognize in earnings the decline in the fair value of ourinvestments below their cost basis when the decline is judged to be other than temporary. We have invested a significant amount in Ctrip convertible notesand ADSs. See Note 4 to our Consolidated Balance Sheets for more information regarding our investments in Ctrip securities. The value of these securities issubject to the risks associated with Ctrip's business, as well as any changes by the Chinese government in foreign investment laws or elevated scrutiny orregulation of foreign investments in Chinese companies. For example, because of foreign ownership restrictions applicable to its business, Ctrip is a CaymanIslands company operating in China through what is commonly referred to as a variable interest entity, or VIE, structure where it conducts part of its businessthrough contractual relationships with affiliated Chinese entities. Although VIE structures are commonly used by Chinese Internet and e-commercecompanies, there are substantial uncertainties regarding the interpretation and application of PRC laws and regulations to VIE structures, and it is possiblethat the PRC government may view the VIE structure as in violation of PRC law. VIE contractual relationships are not as effective in providing control overthe affiliated Chinese companies as direct ownership, and Ctrip would have to rely on the PRC legal system to enforce those contracts in the event of a breachby one of these entities. Further, conflicts of interest could arise to the extent Ctrip's officers or directors are27 also shareholders, officers or directors of the affiliated Chinese entities. Any of these risks could materially and adversely affect Ctrip's business and thereforethe value of our investment in Ctrip.We also invest from time to time in private companies and these investments are generally accounted for under the cost method. Such investmentsare inherently risky in that such companies are typically at an early stage of development, may have no or limited revenues, may not be or ever becomeprofitable, may not be able to secure additional funding or their technologies, services or products may not be successfully developed or introduced to themarket. Further, our ability to liquidate any such investments is typically dependent on a liquidity event, such as a public offering or acquisition, as nopublic market exists for such securities. Valuations of privately-held companies are inherently complex and uncertain due to the lack of a liquid market forthe company's securities. If we determine that any of our investments in such companies have experienced a decline in value, we may be required to record another-than-temporary impairment. For example, during the first quarter of 2016, we recognized an other-than-temporary impairment of approximately $50million related to our cost-method investment in Hotel Urbano, and in the second quarter of 2016, after discussions with Hotel Urbano's management, werecognized a further impairment of approximately $10 million to write-off the remainder of our investment in Hotel Urbano. In addition, during the secondquarter of 2016 we recognized an impairment of approximately $3 million for an investment in another private company. See Note 4 to the ConsolidatedFinancial Statements.We could lose the full amount of any of our investments, and any impairment of our investments could have a material adverse effect on ourfinancial condition and results of operations.Investment in new business strategies and acquisitions could disrupt our ongoing business and present risks not originally contemplated.We have invested, and in the future may invest, in new business strategies and acquisitions. Such endeavors may involve significant risks anduncertainties, including distraction of management from current operations, greater than expected liabilities and expenses, inadequate return on capital, andunidentified issues not discovered in our investigations and evaluations of those strategies and acquisitions. We may decide to make minority investments,including through joint ventures, in which we have limited or no management or operational control. The controlling person in such a case may havebusiness interests, strategies or goals that are inconsistent with ours, and decisions of the company or venture in which we invested may result in harm to ourreputation or adversely affect the value of our investment. A substantial portion of our goodwill and intangible assets were acquired in acquisitions. If wedetermine that any of the goodwill and intangible assets, or any goodwill or intangible assets acquired in future transactions, experiences a decline in value,we may be required to record an other-than-temporary impairment, which could materially adversely affect our results of operations. Further, we may issueshares of our common stock in these transactions, which could result in dilution to our stockholders.Our use of "open source" software could adversely affect our ability to protect our proprietary software and subject us to possible litigation.We use open source software in connection with our software development. From time to time, companies that use open source software have facedclaims challenging the use of open source software and/or compliance with open source license terms. We could be subject to suits by parties claimingownership of what we believe to be open source software, or claiming non-compliance with open source licensing terms. Some open source licenses requireusers who distribute software containing open source to make available all or part of such software, which in some circumstances could include valuableproprietary code of the user. While we monitor our use of open source software and try to ensure that none is used in a manner that would require us todisclose our proprietary source code or that would otherwise breach the terms of an open source agreement, such use could inadvertently occur, in partbecause open source license terms are often ambiguous. Any requirement to disclose our proprietary source code or pay damages for breach of contract couldbe harmful to our business, results of operations or financial condition, and could help our competitors develop services that are similar to or better than ours.Our business is exposed to risks associated with processing credit card transactions.Our results have been negatively impacted by purchases made using fraudulent credit cards. Because we facilitate the processing of customer creditcards in many of our transactions, including a majority of our priceline.com, agoda.com and Rentalcars.com transactions, we may be held liable for acceptingfraudulent credit cards on our websites as well as other payment disputes with our customers. Additionally, we may be held liable for accepting fraudulentcredit cards in certain transactions when we do not facilitate the processing of customer credit cards. Accordingly, we calculate and record an allowance forthe resulting customer chargebacks. If we are unable to combat the use of fraudulent credit cards on our websites, our business, results of operations andfinancial condition could be materially adversely affected.28 In addition, in the event that one of our major travel service providers voluntarily or involuntarily declares bankruptcy, we could experience anincrease in chargebacks from customers with travel reservations with such travel service provider. For example, airlines that participate in our services anddeclare bankruptcy or cease operations may be unable or unwilling to honor tickets sold for their flights. Our policy in such event is to direct customersseeking a refund or exchange to the airline, and not to provide a remedy ourselves. Because we process sales of Express Deals® airline tickets on a merchantbasis, we could experience a significant increase in demands for refunds or credit card chargebacks from customers, which could materially adversely affectour results of operations and financial condition. We have in the past experienced an increase in chargebacks from customers with tickets on airlines thatceased operations. We process credit card transactions and operate in numerous currencies. Credit card and other payment processing costs are typicallyhigher for foreign currency transactions and in instances where cancellations occur.Item 1B. Unresolved Staff Comments None. Item 2.

Management's Discussion and Analysis of Financial Condition and Results of Operations The following discussion should be read in conjunction with our Consolidated Financial Statements, including the notes to those statements,included elsewhere in this Annual Report on Form 10-K, and the Section entitled "Special Note Regarding Forward-Looking Statements" in this AnnualReport on Form 10-K. As discussed in more detail in the Section entitled "Special Note Regarding Forward-Looking Statements," this discussioncontains forward-looking statements which involve risks and uncertainties. Our actual results may differ materially from the results discussed in theforward-looking statements. Factors that might cause those differences include those discussed in "Risk Factors" and elsewhere in this Annual Report onForm 10-K.We evaluate certain operating and financial measures on both an as-reported and constant-currency basis. We calculate constant currency byconverting our current-year period financial results for transactions recorded in currencies other than U.S. Dollars using the corresponding prior-yearperiod monthly average exchange rates rather than the current-year period monthly average exchange rates.OverviewOur mission is to help people experience the world. We seek to achieve our mission by providing consumers, travel service providers and restaurantswith worldwide leadership in online reservation and related services. We operate six primary, independently managed brands:•Booking.com - the world’s leading brand for booking online accommodation reservations, based on room nights booked.•priceline.com - a leading hotel, rental car, airline ticket and vacation package reservation service in the United States.•KAYAK - a leading meta-search service allowing consumers to easily search and compare travel itineraries and prices, including airline ticket,accommodation and rental car reservation information.•agoda.com - a leading accommodation reservation service catering primarily to consumers in the Asia-Pacific region.•Rentalcars.com - a leading worldwide rental car reservation service.•OpenTable - a leading provider of restaurant reservation and information services to consumers and restaurant reservation management servicesto restaurants.We refer to our company and all of our subsidiaries and brands collectively as "The Priceline Group," the "Company," "we," "our" or "us."Our business is driven primarily by international results, which consist of the results of Booking.com, agoda.com and Rentalcars.com and theinternational businesses of KAYAK and OpenTable (in each case regardless of where the consumer resides, where the consumer is physically located whileusing our services or the location of the travel service provider or restaurant). During the year ended December 31, 2016, our international business (thesubstantial majority of which is generated by Booking.com) represented approximately 88% of our consolidated gross profit. A significant majority of ourgross profit is earned in connection with facilitating accommodation reservations. See Note 16 to the Consolidated Financial Statements for more geographicinformation.We derive substantially all of our gross profit from the following sources:•Commissions earned from facilitating reservations of accommodations, rental cars, cruises and other travel services on an agency basis;•Transaction gross profit on a merchant basis and customer processing fees from our accommodation, rental car, airline ticket and vacationpackage reservation services;•Advertising revenues primarily earned by KAYAK from sending referrals to OTCs and travel service providers, as well as from advertisingplacements on KAYAK's websites and mobile apps;•Beginning on July 24, 2014, reservation revenues paid by restaurants for diners seated through OpenTable's online reservation services,subscription fees for restaurant reservation management services provided by OpenTable and other OpenTable revenues; and•Damage excess waiver fees, travel insurance fees and global distribution system ("GDS") reservation booking fees, in each case related to certainof our travel services.34 Our priceline.com brand offers merchant Name Your Own Price® opaque travel services, which are recorded in revenue on a "gross" basis and haveassociated cost of revenue. All of our other services are recorded in revenue on a "net" basis and have no associated cost of revenue. Therefore, revenueincreases and decreases are impacted by changes in the mix of our revenues between Name Your Own Price® travel services and other services. Gross profitreflects the commission or net margin earned for all of our services. Consequently, gross profit is an important measure to evaluate growth in our businessbecause, in contrast to our revenues, it is not affected by the different methods of recording revenue and cost of revenue between our Name Your Own Price®travel reservation services and our other services.TrendsOver the last several years we have experienced strong growth in our accommodation reservation services. We believe this growth is the result of,among other things, the broader shift of travel purchases from offline to online, the widespread adoption of mobile devices, the high growth of travel overallin emerging markets such as Asia-Pacific and South America, and the continued innovation and execution by our teams around the world to buildaccommodation supply, content and distribution and to improve the consumer experience on our websites and mobile apps. These year-over-year growthrates have generally decelerated. Given the size of our accommodation reservation business, we expect that our year-over-year growth rates will generallycontinue to decelerate, though the rate of deceleration may fluctuate and there may be periods of acceleration from time to time. For example, for the yearended December 31, 2016, our accommodation room night reservation growth was 29%, as compared to 25% in 2015, 28% in 2014, 37% in 2013 and 40% in2012.Our international business represents the substantial majority of our financial results, and we expect our operating results and other financial metricsto continue to be largely driven by international performance. The size of the travel market outside of the United States is substantially greater than thatwithin the United States. Historically, Internet use and e-commerce activity of international consumers have trailed that of consumers in the United States.However, international consumers are increasingly moving to online means for purchasing travel. Accordingly, recent international online travel growth rateshave substantially exceeded, and are expected to continue to exceed, the growth rates within the United States. We expect that over the long term,international online travel growth rates will follow a similar trend to that experienced in the United States. In addition, the base of hotel properties in Europeand Asia is particularly fragmented compared to that in the United States, where the hotel market is dominated by large hotel chains. We believe onlinereservation systems like ours may be more appealing to small chains and independent hotels more commonly found outside of the United States. We believethese trends and factors have enabled us to become the leading online accommodation reservation service provider in the world as measured by room nightsbooked. We believe that the opportunity to continue to grow our business exists for the markets in which we operate.Our growth has primarily been generated by our worldwide accommodation reservation service brand, Booking.com, which is our most significantbrand, and has been due, in part, to the availability of a large and growing number of directly bookable properties through Booking.com. Booking.comincluded over 1,115,000 properties on its website as of December 31, 2016, which included over 568,000 vacation rental properties (updated property countsare available on the Booking.com website), and compares to over 852,000 properties (including over 390,000 vacation rental properties) as of December 31,2015.We intend to continue to invest in adding accommodations available for reservation on our websites, including hotels, bed and breakfasts, hostelsand vacation rentals. Vacation rentals generally consist of, among others, properties categorized as single-unit and multi-unit villas, apartments, "aparthotels"(which are apartments with a front desk and cleaning service) and chalets and are generally self-catered (i.e., include a kitchen), directly bookable properties.Many of the newer accommodations we add to our travel reservation services, especially in highly penetrated markets, may have fewer rooms or higher creditrisk and may appeal to a smaller subset of consumers (e.g., hostels and bed and breakfasts). Because a vacation rental is typically either a single unit or asmall collection of independent units, vacation rental accommodations represent more limited booking opportunities than non-vacation rental properties,which generally have more units to rent per property. Our vacation rental accommodations in general may be subject to increased seasonality due to localtourism seasons, weather or other factors. Our vacation rental accommodation business may also experience lower profit margins due to certain additionalcosts related to offering these accommodations on our websites. As we increase our vacation rental accommodation business, these different characteristicscould negatively impact our profit margins; and, to the extent these properties represent an increasing percentage of the properties added to our websites, weexpect that our gross bookings growth rate and property growth rate will continue to diverge over time (since each such property has fewer bookingopportunities). As a result of the foregoing, as the percentage of vacation rental properties increases, we expect that the number of reservations per propertywill likely continue to decrease. We believe that continuing to expand the number and variety of accommodations available through our services, inparticular Booking.com, will help us to continue to grow our accommodation reservation business.35 As part of our strategy to increase the number and variety of accommodations available on Booking.com, Booking.com is increasingly processingtransactions on a merchant basis where it facilitates payments on behalf of customers. This allows Booking.com to process transactions for properties that donot accept credit cards and to increase its ability to offer flexible transaction terms to consumers, such as the form and timing of payment. Although we willincur additional payment processing costs and chargebacks related to these transactions, which are recorded as sales and marketing expenses in our statementof operations and which will negatively impact our operating margins, we believe that adding these types of properties and service offerings will benefit ourcustomers and our gross bookings, room night and earnings growth rates.Concerns persist about the outlook for the global economy in general, including uncertainty in the European Union and China. Perceived or actualadverse economic conditions, including slow, slowing or negative economic growth, unemployment rates and weakening currencies and concerns overgovernment responses such as higher taxes and reduced government spending, could impair consumer spending and adversely affect travel demand. Further,uncertainty regarding the future of the European Union following the United Kingdom’s vote to leave (“Brexit”) and concerns regarding certain E.U.members with sovereign debt default risks could also negatively affect consumer spending and adversely affect travel demand. At times, we have experiencedvolatility in transaction growth rates, increased cancellation rates and weaker trends in hotel ADRs across many regions of the world, particularly in thosecountries that appear to be most affected by economic uncertainties, which we believe are due at least in part to macro-economic conditions and concerns.For more detail, see Part I Item 1A Risk Factors - "Declines or disruptions in the travel industry could adversely affect our business and financialperformance."These and other macro-economic uncertainties, such as sovereign default risk becoming more widespread, declining oil prices, geopolitical tensionsand differing central bank monetary policies, have led to significant volatility in the exchange rates between the U.S. Dollar and the Euro, the British PoundSterling and other currencies. Significant fluctuations in currency exchange rates, stock markets and oil prices can also impact consumer travel behavior.As noted earlier, our international business represents a substantial majority of our financial results. Therefore, because we report our results in U.S.Dollars, we face exposure to adverse movements in currency exchange rates as the financial results of our international businesses are translated from localcurrency (principally Euros and British Pounds Sterling) into U.S. Dollars. Throughout 2015, the U.S. Dollar strengthened significantly year-over-yearrelative to substantially all currencies in which we transact, most notably the Euro, Brazilian Real, British Pound Sterling, Russian Ruble and AustralianDollar. In 2016, the U.S. Dollar continued to be stronger year-over-year relative to the British Pound Sterling, Russian Ruble and many other major currenciesin which we transact. Since the "Brexit" referendum in the United Kingdom in June 2016, the U.S. Dollar has strengthened significantly against the BritishPound Sterling. As a result of these currency exchange rate changes, our foreign currency denominated net assets, gross bookings, gross profit, operatingexpenses and net income have been negatively impacted as expressed in U.S. Dollars, although to a much lesser extent in 2016 than in 2015. For example,gross profit from our international operations grew 22.3% for the year ended December 31, 2016 compared to the year ended December 31, 2015, but, withoutthe negative impact of changes in currency exchange rates, grew year-over-year on a constant-currency basis by approximately 25%. Since our expenses aregenerally denominated in foreign currencies on a basis similar to our revenues, our operating margins are not significantly impacted by currency fluctuations.The aggregate principal value of our Euro-denominated 2022 Notes, 2024 Notes and 2027 Notes, and accrued interest thereon, provide a natural hedge of thenet assets of certain of our Euro functional currency subsidiaries. For more information, see Part I Item 1A Risk Factors - "We are exposed to fluctuations incurrency exchange rates."We generally enter into derivative instruments to minimize the impact of short-term currency fluctuations on the translation of our consolidatedoperating results into U.S. Dollars. However, such derivative instruments are short term in nature and not designed to hedge against currency fluctuations thatcould impact growth rates for our gross bookings, revenues or gross profit (see Note 5 to the Consolidated Financial Statements for additional information onour derivative contracts).We compete globally with both online and traditional providers of travel and restaurant reservation and related services. The markets for the serviceswe offer are intensely competitive and current and new competitors can launch new services at a relatively low cost. Some of our current and potentialcompetitors, such as Google, Apple, Alibaba, Amazon and Facebook, have access to significantly greater and more diversified resources than we do, and theymay be able to leverage other aspects of their businesses (e.g., search or mobile device businesses) to enable them to compete more effectively with us. Forexample, Google has entered various aspects of the online travel market, including by establishing a flight meta-search product (“Google Flights”) and ahotel meta-search business ("Hotel Ads") that are growing rapidly, as well as its "Book on Google" reservation functionality. Our markets are also subject torapidly changing conditions, including technological developments, consumer behavior changes, regulatory changes and travel service providerconsolidation. We expect these trends to continue. For example, we have experienced a significant shift of both direct and indirect business to mobileplatforms and our advertising partners are also seeing a rapid shift of traffic to mobile platforms. Advertising and distribution36 opportunities may be more limited on mobile devices given their smaller screen sizes. In addition, the gross profit earned on a mobile transaction may be lessthan a typical desktop transaction due to different consumer purchasing patterns. For example, accommodation reservations made on a mobile devicetypically are for shorter lengths of stay and are not made as far in advance. For more detail regarding the competitive trends and risks we face, see Part I Item 1Business - "Competition", Part I Item 1A Risk Factors - "Intense competition could reduce our market share and harm our financial performance." and"Consumer adoption and use of mobile devices creates new challenges and may enable device companies such as Apple to compete directly with us." and"We may not be able to keep up with rapid technological changes."We have observed an increase in promotional pricing to closed user groups (such as loyalty program participants or consumers with registeredaccounts), including through mobile apps. For example, Marriott International, Hilton, Hyatt Hotels, InterContinental Hotel Group and Choice HotelsInternational have launched additional initiatives to encourage consumers to book accommodations directly through their websites, with increaseddiscounting and incentives.In addition to providing retail travel reservation services, our priceline.com brand is a leading provider of discounted opaque travel reservationservices in the United States through its Name Your Own Price® and Express Deals® offerings. These discounted services are referred to as "opaque" becausecertain elements of the reservation, including the name of the travel service provider, are not made known to the traveler until after the reservation is made. Ingeneral, we expect that over time our opaque services will continue to decrease in relative importance to our overall business due, we believe, to a variety offactors, including the growth rates of our retail businesses, competition, relative complexity, travel restrictions often required by the travel service provider,difficulty in offering these services on mobile devices, increased discounts available to consumers through closed user groups, and limited availability ofdiscounted travel reservations from travel service providers, particularly during periods of high consumer demand.We have established widely used and recognized e-commerce brands through marketing and promotional campaigns. Both our performance andbrand advertising expenses have increased significantly in recent years, a trend we expect to continue. For the years ended December 31, 2016, 2015 and2014, our total performance advertising expense was approximately $3.5 billion, $2.7 billion and $2.3 billion, respectively, primarily related to the use ofonline search engines (primarily Google), meta-search and travel research services and affiliate marketing to generate traffic to our websites. We also investedapproximately $296 million, $274 million and $257 million in brand advertising during 2016, 2015 and 2014, respectively, primarily related to costsassociated with producing and airing television advertising, online video advertising (for example, on YouTube and Facebook) and online displayadvertising. We intend to continue a strategy of promoting brand awareness through both online and offline advertising efforts, including by expandingbrand campaigns into additional markets. We have observed increased brand advertising by OTCs, meta-search services and travel service providers,particularly in North America and Europe, which may make our brand advertising efforts more expensive and less effective.Performance advertising efficiency, expressed as performance advertising expense as a percentage of gross profit, is impacted by a number of factorsthat are subject to variability and that are, in some cases, outside of our control, including ADRs, costs per click, cancellation rates, foreign exchange rates,our ability to convert paid traffic to booking customers and the extent to which consumers come directly to our websites or mobile apps for bookings. Forexample, competition for desired rankings in search results and/or a decline in ad clicks by consumers could increase our costs-per-click and reduce ourperformance advertising efficiency. We have also experienced increasing cancellation rates, which we expect to continue and which negatively affects ouradvertising efficiency and results of operations. Changes by Google in how it presents travel search results, including by placing its own offerings at or nearthe top of search results, or the manner in which it conducts the auction for placement among search results may be competitively disadvantageous to us andmay impact our ability to efficiently generate traffic to our websites. We have observed a long-term trend of decreasing performance advertising returns oninvestment ("ROIs"), a trend we expect to continue, though the rate of decrease may fluctuate and there may be periods of stable or increasing ROIs from timeto time. See Part I Item 1A Risk Factors - "We rely on performance and brand advertising channels to generate a significant amount of traffic to our websitesand grow our business." and "Our business could be negatively affected by changes in Internet search engine algorithms and dynamics or traffic-generatingarrangements."The national competition authorities ("NCAs") of many governments have conducted or are conducting investigations into competitive practiceswithin the online travel industry, and we may be involved or affected by such investigations and their results. Some countries have adopted or proposedlegislation that could also affect business practices within the online travel industry. For example, in August 2015, France adopted legislation known as the"Macron Law" making price parity agreements illegal, including those that had been approved by the French NCA, and similar legislation may be enacted inother counties. For more information on these investigations and their potential effects on our business, see Note 14 to our Consolidated Financial Statementsand Part I Item 1A Risk Factors - "As the size of our business grows, we may become increasingly subject to the scrutiny of anti-trust and competitionregulators."37 SeasonalityA meaningful amount of our gross bookings are generated early in the year, as customers plan and reserve their spring and summer vacations inEurope and North America. However, we generally do not recognize revenue from these bookings until the travel occurs, which can be in a quarter other thanwhen the reservation is booked. In contrast, we expense the substantial majority of our advertising activities as the expense is incurred, which, in the case ofperformance advertising in particular, is typically in the quarter in which associated reservations are booked. As a result of this potential timing differencebetween when we record advertising expense and when we recognize associated revenue, we have historically experienced our highest levels of profitabilityin the second and third quarters of the year, which is when we experience the highest levels of accommodation checkouts for the year for our European andNorth American businesses. The first quarter of the year is typically our lowest level of profitability and may experience volatility in earnings growth ratesdue to these seasonal timing factors. For our Asia-Pacific business, we experience the highest levels of accommodation bookings in the third and fourthquarters of the year, and the highest levels of travel consumption in the fourth quarter. As the relative growth rates for these businesses fluctuate, the quarterlydistribution of our operating results may vary.In addition, the date on which certain holidays fall can have an impact on our quarterly results. For example, in 2016, our first quarter year-over-yeargrowth rates in revenue, gross profit, operating income and operating margins were positively impacted by Easter falling in the first quarter instead of thesecond quarter, as it did in 2015. Conversely, our second quarter 2016 year-over-year growth rates in revenue, gross profit, operating income and operatingmargins were adversely impacted by Easter falling in the first quarter instead of the second quarter, as it did in 2015. Similarly to 2015, in 2017 Easter willfall in the second quarter instead of the first quarter, and will therefore have a negative effect on our first quarter 2017 year-over-year growth rates and apositive effect on our second quarter 2017 year-over-year growth rates as compared to the same periods in 2016 when Easter fell in the first quarter. Thetiming of other holidays such as Chinese New Year, Carnival and Ramadan can also impact our quarterly year-over-year growth rates.The impact of seasonality can be exaggerated in the short term by the gross bookings growth rate of the business. For example, in periods where ourgross bookings growth rate substantially decelerates, our operating margins typically benefit from relatively less variable advertising expense. In addition,gross profit growth is typically less impacted by decelerating gross bookings growth in the near term due to the benefit of revenue related to reservationsbooked in previous quarters. Conversely, in periods where our gross bookings growth rate accelerates, our operating margins are typically negativelyimpacted by relatively more variable advertising expense. In addition, gross profit growth is typically less impacted by accelerating gross bookings growth inthe near term as a portion of the revenue recognized from such gross bookings will occur in future quarters.Other FactorsWe believe that our future success depends in large part on our ability to continue to profitably grow our brands worldwide, and, over time, to offerother travel and travel-related services. Factors beyond our control, such as worldwide recession, oil prices, terrorist attacks, unusual or extreme weather ornatural disasters such as earthquakes, hurricanes, tsunamis, floods, droughts and volcanic eruptions, travel-related health concerns including pandemics andepidemics such as Ebola, Zika, Influenza H1N1, avian bird flu, SARS and MERS, political instability, regional hostilities, imposition of taxes or surchargesby regulatory authorities or travel-related accidents, can disrupt travel or otherwise result in declines in travel demand. Because these events or concerns arelargely unpredictable, they can dramatically and suddenly affect travel behavior by consumers, and therefore demand for our services, which can adverselyaffect our business and results of operations. See Part I Item 1A Risk Factors - “Declines or disruptions in the travel industry could adversely affect ourbusiness and financial performance.”We intend to continue to invest in marketing and promotion, technology and personnel within parameters consistent with attempts to improve long-term operating results, even if those expenditures create pressure on operating margins. We have experienced pressure on operating margins as we prioritizeinitiatives that drive growth. We also intend to broaden the scope of our business, and to that end, we explore strategic alternatives from time to time in theform of, among other things, mergers and acquisitions. Our goal is to grow gross profit and achieve healthy operating margins in an effort to maintainprofitability. The uncertain and highly competitive environment in which we operate makes the prediction of future results of operations difficult, andaccordingly, we may not be able to sustain gross profit growth and profitability.Critical Accounting Policies and EstimatesManagement's Discussion and Analysis of Financial Condition and Results of Operations is based upon our Consolidated Financial Statements,which have been prepared in accordance with accounting principles generally accepted in the United States. Our significant accounting policies andestimates are more fully described in Note 2 to the Consolidated38 Financial Statements. Certain of our accounting estimates are particularly important to our financial position and results of operations and require us to makedifficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Our management uses its judgmentto determine the appropriate assumptions to be used in the determination of certain estimates. We evaluate our estimates on an ongoing basis. Estimates arebased on, among other things, historical experience, terms of existing contracts, our observance of trends in the travel industry and on various otherassumptions that we believe to be reasonable under the circumstances. Our actual results may differ from these estimates under different assumptions orconditions. Our critical accounting policies that involve significant estimates and judgments of management include the following:•Stock-Based Compensation. We record stock-based compensation expense for equity-based awards over the recipient's service period basedupon the grant date fair value of the award. A number of our equity awards have performance targets (a performance "contingency") which,if satisfied, can increase the number of shares issued to the recipients at the end of the performance period or, in certain instances, if notsatisfied, reduce the number of shares issued to the recipients, sometimes to zero, at the end of the performance period. The performanceperiods for our performance based equity awards are typically three years. We record stock-based compensation expense for theseperformance-based awards based upon our estimate of the probable outcome at the end of the performance period (i.e., the estimatedperformance against the performance targets). We periodically adjust the cumulative stock-based compensation expense recorded when theprobable outcome for these performance-based awards is updated based upon changes in actual and forecasted operating results. Stock-based compensation expense for the years ended December 31, 2016, 2015 and 2014 includes charges amounting to $20.7 million, $22.6million and $20.6 million, respectively, representing the impact of adjusting the estimated probable outcome of unvested performanceshare units. Our actual performance against the performance targets could differ materially from our estimates.We record stock-based compensation expense net of estimated forfeitures. In determining the estimated forfeiture rates, we periodicallyreview actual forfeitures and update our estimates for future forfeitures, if necessary. To the extent that actual forfeiture rates differ fromcurrent estimates, a cumulative expense adjustment is recorded in the period in which the estimate is revised (see "Recent AccountingPronouncements" described in Note 2 to the Consolidated Financial Statements for accounting changes that are effective January 1, 2017).•Valuation of Goodwill, Long-Lived Assets and Intangibles. The application of the purchase method of accounting for businesscombinations requires the use of significant estimates and assumptions to determine the fair value of the assets acquired and liabilitiesassumed. Our estimates of the fair value are based upon assumptions that we believe are reasonable and, when we deem appropriate, includeassistance from a third party valuation firm. The purchase price consideration is allocated to the assets acquired and liabilities assumedbased on their respective fair values at the acquisition date. The excess of the purchase price consideration over the net of the amountsallocated to the assets acquired and liabilities assumed is recognized as goodwill. Goodwill is assigned to reporting units that are expectedto benefit from the synergies of the business combination as of the acquisition date.We review goodwill for impairment annually and whenever events or changes in circumstances indicate the carrying amount of goodwillmay not be recoverable. A substantial portion of our intangibles and goodwill relates to the acquisitions of OpenTable in July 2014 andKAYAK in May 2013. As of September 30, 2016, we performed our annual goodwill impairment testing. Other than OpenTable, the fairvalues of our reporting units substantially exceeded their respective carrying values. For OpenTable, we recognized a non-cash impairmentcharge for goodwill of $940.7 million, which is not tax deductible, resulting in an adjusted carrying value of OpenTable goodwill of$580.1 million as of September 30, 2016. The goodwill impairment charge was included in operating expenses in the ConsolidatedStatement of Operations for the year ended December 31, 2016. OpenTable’s estimated fair value was determined using a combination ofstandard valuation techniques, including an income approach (discounted cash flows) and market approaches (EBITDA multiples ofcomparable publicly-traded companies and precedent transactions). Since the annual impairment test as of September 30, 2016, there havebeen no further events or changes in circumstances to indicate a potential impairment.The goodwill impairment is primarily the result of a change in OpenTable’s business strategy that occurred during the third quarter of 2016.OpenTable’s post-acquisition strategy was premised on significant and rapid investment in international expansion and various othergrowth initiatives, resulting in near-term reduced earnings and profit margins but with the goal of achieving significantly increasedrevenues and profitability39 in the long term. This strategy has resulted in limited progress to date. As a result, while OpenTable intends to continue to pursue and investin international expansion and its other growth initiatives, it intends to do so in a more measured and deliberate manner. This change instrategy resulted in OpenTable updating its forecasted financial results to reflect (a) a material reduction in forecasted long-term financialresults from these initiatives, partially offset by (b) improved earnings and profit margins in the near term as a result of the reducedinvestments. Based on the updated forecast, we estimated a significant reduction in the fair value of the OpenTable business and recordedthe goodwill impairment discussed above.Future events and changing market conditions may lead us to again re-evaluate the assumptions reflected in the updated forecast, includingkey assumptions regarding OpenTable's expected growth rates and operating margins and the success and timing of its internationalexpansion and other growth initiatives, as well as other key assumptions with respect to matters outside of our control, such as discountrates, currency exchange rates, market EBITDA comparables, and changes in accounting policies or practices, including the January 2017accounting update that changes the goodwill impairment testing methodology (see Note 2 to the Consolidated Financial Statements). IfOpenTable does not achieve the results currently expected, its investments, in particular its investments in its international expansionefforts and other growth initiatives, are not successful, or any of the assumptions underlying our estimate of the value of the OpenTablebusiness, including those mentioned above, prove to be incorrect, we may further refine our forecast for the OpenTable business andrecognize an additional goodwill impairment, which could have a material adverse effect on our results of operations.Additionally, we evaluate whether events or circumstances have occurred which indicate that the carrying amounts of long-lived assets andintangibles may not be recoverable. The significant factors that are considered that could trigger an impairment review include changes inbusiness strategies, market conditions, or the manner of use of an asset; under performance relative to historical or expected future operatingresults; and negative industry or economic trends. In evaluating an asset for possible impairment, management estimates that asset's futureundiscounted cash flows to measure whether the carrying value of the asset is recoverable. If it is determined that the asset is notrecoverable, we measure the impairment based upon the fair value of the asset compared to its carrying value. The fair value represents theprojected discounted cash flows of the asset over its remaining life. We tested the recoverability of OpenTable’s other long-lived assets andconcluded there was no impairment as of September 30, 2016.•Income Taxes. We determine our tax expense based on our income and statutory tax rates applicable in the various jurisdictions in whichwe operate. Due to the complex nature of tax legislation and frequent changes with such associated legislation, significant judgment isrequired in computing our tax expense and determining our tax positions. We regularly review our deferred tax assets for recoverabilityconsidering historical profitability, projected future taxable income, the expected timing of the reversals of temporary differences and taxplanning strategies and record valuation allowances as required.We are subject to ongoing tax examinations and assessments in various jurisdictions. To date, we have been audited in several taxingjurisdictions with no significant impact on our financial condition, results of operations or cash flows. Although we believe that our taxfiling positions are reasonable, the final determination of tax audits or tax disputes may be different from what is reflected in our historicalincome tax provisions and accruals. Accordingly, we may incur additional tax expense based upon our assessment of the more likely thannot outcomes or we may adjust previously recorded tax expense to reflect examination results.We intend to indefinitely reinvest the unremitted earnings of our international subsidiaries outside of the United States. At December 31,2016 and 2015, we had approximately $13.0 billion and $9.9 billion, respectively, of cumulative unremitted international earnings. Weestimate that the deferred tax liability we would record if such earnings were not indefinitely reinvested internationally is approximately$2.3 billion as of December 31, 2016.Recent Accounting Pronouncements - See Note 2 to the Consolidated Financial Statements for details, which is incorporated into this Item 7 byreference thereto.40 Results of Operations Year Ended December 31, 2016 compared to Year Ended December 31, 2015 Operating and Statistical Metrics Our financial results are driven by certain operating metrics that encompass the booking and other business activity generated by our travel andtravel-related services. Specifically, reservations of accommodation room nights, rental car days and airline tickets capture the volume of units bookedthrough our OTC brands by our travel reservation services customers. Gross bookings is an operating and statistical metric that captures the total dollarvalue, generally inclusive of taxes and fees, of all travel services booked through our OTC brands by our customers, net of cancellations, and is widely usedin the travel business. Our non-OTC brands (KAYAK and OpenTable) have different business metrics from those of our OTC brands and therefore searchqueries through KAYAK and restaurant reservations through OpenTable do not contribute to our gross bookings.Gross bookings resulting from reservations of accommodation room nights, rental car days and airline tickets made through our agency andmerchant models for the years ended December 31, 2016 and 2015 were as follows (numbers may not total due to rounding): Year Ended December 31, (in millions) 2016 2015 ChangeAgency$58,638 $47,969 22.2%Merchant9,449 7,559 25.0%Total$68,087 $55,528 22.6% Gross bookings increased by 22.6% for the year ended December 31, 2016, compared to the year ended December 31, 2015 (growth on a constant-currency basis was approximately 25%), principally due to growth of 28.7% in accommodation room night reservations and growth of 11.2% in rental carday reservations, partially offset by the impact of foreign exchange rate fluctuations, a slight decrease in accommodation ADRs (the decline on a constant-currency basis was less than 1%) and decreases in airfares and airline ticket reservations. We believe that unit growth rates and total gross bookings and grossprofit growth on a constant-currency basis, each of which exclude the impact of foreign exchange rate fluctuations, are important measures to understand thefundamental performance of the business.Agency gross bookings are derived from travel-related transactions where we do not facilitate payments for the travel services provided. Agencygross bookings increased by 22.2% for the year ended December 31, 2016, compared to the year ended December 31, 2015, primarily due to growth in grossbookings from Booking.com agency retail accommodation room night reservations.Merchant gross bookings are derived from services where we facilitate payments for the travel services provided. Merchant gross bookings increasedby 25.0% for the year ended December 31, 2016, compared to the year ended December 31, 2015, primarily due to growth in gross bookings from themerchant accommodation reservation services for Booking.com and agoda.com, the merchant rental car reservation service for Rentalcars.com and themerchant airline ticket reservation service for priceline.com.Accommodation room nights, rental car days and airline tickets reserved through our services for the years ended December 31, 2016 and 2015 wereas follows:Year Ended December 31, (in millions) 2016 2015 ChangeRoom Nights556.6 432.3 28.7 %Rental Car Days66.6 59.9 11.2 %Airline Tickets7.3 7.7 (5.2)% Accommodation room night reservations increased by 28.7% for the year ended December 31, 2016, compared to the year ended December 31,2015, primarily due to strong execution by our brand teams to add accommodations to our websites,41 advertise our brands to consumers and provide a continuously improving experience for customers on our desktop and mobile platforms.Rental car day reservations increased by 11.2% for the year ended December 31, 2016, compared to the year ended December 31, 2015, due to anincrease in rental car day reservations for Rentalcars.com.Airline ticket reservations decreased by 5.2% for the year ended December 31, 2016, compared to the year ended December 31, 2015, due to adecline in priceline.com's retail airline ticket reservations and the discontinuation on September 1, 2016 of priceline.com’s Name Your Own Price® airlineticket reservation offering, partially offset by an increase in priceline.com's Express Deals® airline ticket reservations. RevenuesWe classify our revenue into three categories: •Agency revenues are derived from travel-related transactions where we do not facilitate payments for the travel services provided. Agencyrevenues consist primarily of travel reservation commissions, as well as certain GDS reservation booking fees and travel insurance fees, and arereported at the net amounts received, without any associated cost of revenue. Substantially all of the revenue for Booking.com is agencyrevenue comprised of accommodation reservation commissions. •Merchant revenues are derived from services where we facilitate payments for the travel services provided. Merchant revenues include (1)transaction net revenues (i.e., the amount charged to a customer, less the amount charged to us by travel service providers) and travel reservationcommissions in connection with (a) the accommodation reservations provided through our merchant retail accommodation reservation servicesat agoda.com, Booking.com and priceline.com and (b) the reservations provided through our merchant rental car service at Rentalcars.com andpriceline.com’s Express Deals® reservation services; (2) transaction revenues representing the price of Name Your Own Price® reservationscharged to a customer (with a corresponding travel service provider cost recorded in cost of revenues); (3) ancillary fees, including damageexcess waiver and travel insurance fees and certain GDS reservation booking fees; and (4) customer processing fees charged in connection with(a) priceline.com's opaque reservation services and (b) the merchant retail accommodation reservation services at priceline.com and agoda.com. •Advertising and other revenues are derived primarily from (1) revenues earned by KAYAK for (a) sending referrals to OTCs and travel serviceproviders and (b) advertising placements on KAYAK's websites and mobile apps; (2) revenues earned by OpenTable for (a) reservation fees (feespaid by restaurants for diners seated through OpenTable's online reservation service) and (b) subscription fees earned by OpenTable forrestaurant reservation management services; (3) revenues earned by priceline.com for advertising on its websites; and (4) revenues generated byBooking.com's BookingSuite branded accommodation marketing and business analytics services.Year Ended December 31, (in thousands) 2016 2015 ChangeAgency Revenues$7,982,116 $6,527,898 22.3 %Merchant Revenues2,048,005 2,082,973 (1.7)%Advertising and Other Revenues712,885 613,116 16.3 %Total Revenues$10,743,006 $9,223,987 16.5 %Agency RevenuesAgency revenues increased by 22.3% for the year ended December 31, 2016, compared to the year ended December 31, 2015, primarily as a result ofgrowth in agency accommodation room night reservations at Booking.com.Merchant RevenuesMerchant revenues decreased by 1.7% for the year ended December 31, 2016, compared to the year ended December 31, 2015, primarily due todecreases in revenues from priceline.com's Name Your Own Price® reservation services,42 partially offset by increases in our merchant price-disclosed accommodation reservation services, particularly at Booking.com, as well as our merchant price-disclosed rental car and airline ticket reservation services. On September 1, 2016, priceline.com’s Name Your Own Price® airline ticket reservation offeringwas discontinued. Our priceline.com Name Your Own Price® reservation services, which declined year-over-year, are recorded "gross" with a correspondingtravel service provider cost recorded in cost of revenues. Our other merchant revenues, which in total grew year-over-year, are recorded in revenue "net" oftravel service provider costs. As a result, changes in Name Your Own Price® reservation revenue disproportionately affect merchant revenues as compared toour other merchant revenues.Advertising and Other RevenuesAdvertising and other revenues during the year ended December 31, 2016 consisted primarily of advertising revenues, restaurant reservationrevenues and subscription revenues for restaurant reservation management services. Advertising and other revenues increased by 16.3% for the year endedDecember 31, 2016, compared to the year ended December 31, 2015, primarily due to growth in our KAYAK business, reservation fees at OpenTable,advertising revenue at priceline.com and subscription revenue at OpenTable. Cost of Revenues Year Ended December 31, (in thousands) 2016 2015 ChangeCost of Revenues$428,314 $632,180 (32.2)% For the year ended December 31, 2016, cost of revenues consisted primarily of: (1) the cost paid to travel service providers for priceline.com's NameYour Own Price® and vacation package reservation services, net of applicable taxes and charges; and (2) fees paid to third parties by KAYAK andpriceline.com to return travel itinerary information for consumer search queries. Cost of revenues decreased by 32.2% for the year ended December 31, 2016,compared to the year ended December 31, 2015, primarily due to a decrease in priceline.com's Name Your Own Price® reservation services. Cost of revenuesfor the year ended December 31, 2016 was positively impacted by a reduction of travel transaction taxes of $5.1 million recorded in the third quarter of 2016related to a cash refund from the State of Hawaii based on a favorable ruling in the first quarter of 2015. Cost of revenues for the year ended December 31,2015 was positively impacted by a reversal of previously accrued travel transaction taxes of $16.4 million (including estimated interest and penalties)recorded in the first quarter of 2015 and a reduction of travel transaction taxes of $13.7 million (including estimated interest and penalties) recorded in thethird quarter of 2015, principally related to a cash refund from the State of Hawaii, in both cases based on the aforementioned favorable ruling.Agency revenues have no cost of revenue.Gross Profit Year Ended December 31, (in thousands) 2016 2015 ChangeGross Profit$10,314,692 $8,591,807 20.1%Gross Margin96.0% 93.1% Total gross profit increased by 20.1% for the year ended December 31, 2016, compared to the year ended December 31, 2015 (growth on a constant-currency basis was approximately 23%), primarily as a result of the increased revenue discussed above. Total gross margin (gross profit as a percentage oftotal revenue) increased during the year ended December 31, 2016, compared to the year ended December 31, 2015, because our revenues aredisproportionately affected by priceline.com's Name Your Own Price® reservation services. Name Your Own Price® revenues are recorded "gross" with acorresponding travel service provider cost recorded in cost of revenues, and in the year ended December 31, 2016 these revenues represented a smallerpercentage of total revenues than in the year ended December 31, 2015. Our price-disclosed reservation services, which are recorded in revenue "net" of travelservice provider costs, have been growing and priceline.com's Name Your Own Price® reservation services have been declining. As a result, we believe thatgross profit is an important measure for evaluating growth in our business.43 Gross profit for the year ended December 31, 2016 was positively impacted by a reduction of travel transaction taxes of $5.1 million recorded in thethird quarter of 2016 related to a cash refund from the State of Hawaii based on a favorable ruling in the first quarter of 2015. Gross profit for the year endedDecember 31, 2015 was positively impacted by a reversal of previously accrued travel transaction taxes of $16.4 million (including estimated interest andpenalties) recorded in the first quarter of 2015 and a reduction of travel transaction taxes of $13.7 million (including estimated interest and penalties)recorded in the third quarter of 2015, principally related to a cash refund from the State of Hawaii, in both cases based on the aforementioned favorableruling.Gross profit as a percentage of gross bookings was 15.1% for the year ended December 31, 2016, as compared to 15.5% for the year ended December31, 2015. The decrease is due in part to the timing of booking versus travel resulting from the impact of accelerating gross bookings growth in the year endedDecember 31, 2016 and an expanding booking window (a lengthening of the average time between the making of a travel reservation and the travel). Othercontributing factors to the variance are business mix impacts and the use of discounted closed user group rates.Our international operations accounted for approximately $9.1 billion of our gross profit for the year ended December 31, 2016, compared to $7.4billion for the year ended December 31, 2015. Gross profit attributable to our international operations increased by 22.3% for the year ended December 31,2016 compared to the year ended December 31, 2015 (growth on a constant-currency basis was approximately 25%). Gross profit attributable to our U.S.businesses increased by 5.7% for the year ended December 31, 2016, compared to the year ended December 31, 2015 due to growth in gross profit for the U.S.businesses of KAYAK and OpenTable, partially offset by a decrease in gross profit for priceline.com resulting from higher favorable travel transaction taxadjustments recorded in 2015 as compared to 2016.Operating Expenses Advertising Year Ended December 31, (in thousands) 2016 2015 ChangePerformance Advertising$3,479,287 $2,738,218 27.1%% of Total Gross Profit33.7% 31.9% Brand Advertising$295,698 $273,704 8.0%% of Total Gross Profit2.9% 3.2% Performance advertising expenses consist primarily of the costs of (1) search engine keyword purchases; (2) referrals from meta-search and travelresearch websites; (3) affiliate programs; and (4) other performance-based advertisements. For the year ended December 31, 2016, performance advertisingexpenses increased compared to the year ended December 31, 2015, primarily to generate increased gross bookings and gross profit. Performance advertisingas a percentage of gross profit for the year ended December 31, 2016 increased compared to the year ended December 31, 2015 due to growth of paid trafficchannels, a year-over-year decline in advertising ROIs and timing of booking versus travel resulting from acceleration in gross bookings growth during theyear.Brand advertising expenses are primarily related to our Booking.com, KAYAK, priceline.com and agoda.com businesses and consist mainly oftelevision advertising, online video advertising (including the airing of our television advertising online) and online display advertising. For the year endedDecember 31, 2016, brand advertising expenses increased compared to the year ended December 31, 2015, primarily due to increased online video andtelevision advertising, including associated production costs, at Booking.com, partially offset by lower television advertising at KAYAK and priceline.com.In January 2016, we changed the presentation of advertising expenses in the Consolidated Statements of Operations (see Note 2 to the ConsolidatedFinancial Statements).44 Sales and Marketing Year Ended December 31, (in thousands) 2016 2015 ChangeSales and Marketing$435,225 $353,221 23.2%% of Total Gross Profit4.2% 4.1% Sales and marketing expenses consist primarily of (1) credit card and other payment processing fees associated with merchant transactions; (2) feespaid to third parties that provide call center, website content translations and other services; (3) customer relations costs; (4) provisions for customerchargebacks associated with merchant transactions; (5) provisions for bad debt, primarily related to agency accommodation commission receivables; and (6)promotional and trade show costs. For the year ended December 31, 2016, sales and marketing expenses, which are substantially variable in nature, increasedcompared to the year ended December 31, 2015 due primarily to increased transaction volumes and a higher provision for customer chargebacks associatedwith merchant transactions.Personnel Year Ended December 31, (in thousands) 2016 2015 ChangePersonnel$1,350,032 $1,166,226 15.8%% of Total Gross Profit13.1% 13.6% Personnel expenses consist of compensation to our personnel, including salaries, stock-based compensation, bonuses, payroll taxes, and employeehealth and other benefits. Personnel expenses increased during the year ended December 31, 2016, compared to the year ended December 31, 2015, dueprimarily to increased headcount to support the growth of our businesses.General and Administrative Year Ended December 31, (in thousands) 2016 2015 ChangeGeneral and Administrative$455,909 $415,420 9.7%% of Total Gross Profit4.4% 4.8% General and administrative expenses consist primarily of: (1) occupancy and office expenses; (2) personnel-related expenses such as travel,recruiting and training expenses; and (3) fees for outside professionals, including litigation expenses. General and administrative expenses increased duringthe year ended December 31, 2016, compared to the year ended December 31, 2015, due primarily to higher occupancy and office expenses related to theexpansion of our international businesses, higher fees for outside professionals and higher personnel-related expenses related to increased headcount in ourbusinesses. These increases were partially offset by $7.7 million of expense recognized in 2015 for a fair value adjustment to the contingent liability relatedto an acquisition.45 Information TechnologyYear Ended December 31, (in thousands) 2016 2015 ChangeInformation Technology$142,393 $113,617 25.3%% of Total Gross Profit1.4% 1.3% Information technology expenses consist primarily of: (1) software license and system maintenance fees; (2) data communications and otherexpenses associated with operating our services; (3) outsourced data center costs; and (4) payments to outside consultants. Information technology expensesincreased during the year ended December 31, 2016, compared to the year ended December 31, 2015, due primarily to growth in our worldwide operations.Depreciation and Amortization Year Ended December 31, (in thousands) 2016 2015 ChangeDepreciation and Amortization$309,135 $272,494 13.4%% of Total Gross Profit3.0% 3.2% Depreciation and amortization expenses consist of: (1) amortization of intangible assets with determinable lives; (2) depreciation on computerequipment; (3) depreciation of internally developed and purchased software; and (4) depreciation of leasehold improvements, furniture and fixtures andoffice equipment. Depreciation and amortization expenses increased during the year ended December 31, 2016, compared to the year ended December 31,2015, primarily as a result of increased depreciation expenses due to capital expenditures for additional data center capacity and office build-outs to supportgrowth and geographic expansion, as well as increased capitalized software development costs.Impairment of Goodwill Year Ended December 31, (in thousands) 2016 2015 ChangeImpairment of Goodwill$940,700 $— N/A% of Total Gross Profit9.1% —% During the year ended December 31, 2016, we recognized a non-cash impairment charge for goodwill related to OpenTable, which is not taxdeductible, of $940.7 million (see Note 9 to the Consolidated Financial Statements and Critical Accounting Policies and Estimates included in thisManagement's Discussion and Analysis of Financial Condition and Results of Operations).Other Income (Expense) Year Ended December 31, (in thousands) 2016 2015 ChangeInterest Income$94,946 $55,729 70.4 %Interest Expense(207,900) (160,229) 29.8 %Foreign Currency Transactions and Other(16,913) (26,087) (35.2)%Impairment of Cost-method Investments(63,208) — N/ATotal$(193,075) $(130,587) 47.9 % For the year ended December 31, 2016, interest income on cash and marketable securities increased compared to the year ended December 31, 2015,primarily due to an increase in the average invested balance and higher yields. Interest46 expense increased for the year ended December 31, 2016, compared to the year ended December 31, 2015, primarily due to interest expense attributable toour Senior Notes issued in March 2015, November 2015 and May 2016, partially offset by the maturity of our 1.25% Convertible Senior Notes in March2015. See Note 10 to our Consolidated Financial Statements."Foreign currency transactions and other" includes foreign exchange gains or losses on derivative contracts, foreign exchange transaction gains orlosses, including costs related to foreign exchange transactions, and net realized gains or losses on investments.Derivative contracts that hedge our exposure to the impact of currency fluctuations on the translation of our international operating results into U.S.Dollars upon consolidation resulted in foreign exchange gains of $3.4 million for the year ended December 31, 2016, compared to foreign exchange losses of$6.6 million for the year ended December 31, 2015.Foreign exchange transaction losses, including costs related to foreign exchange transactions, resulted in foreign exchange losses of $19.6 millionand $21.0 million for the years ended December 31, 2016 and 2015, respectively. Foreign exchange losses for the year ended December 31, 2015 includedapproximately $5.7 million of hedging cost and a foreign exchange loss related to the devaluation of the Argentine Peso.For the year ended December 31, 2016 and 2015, we recognized $1.1 million and $2.2 million, respectively, of net realized gains related toinvestments.During the year ended December 31, 2016, we recognized impairments of $63.2 million, most of which was not tax deductible, related to cost-method investments (see Note 4 to the Consolidated Financial Statements).Income Taxes Year Ended December 31, (in thousands) 2016 2015 ChangeIncome Tax Expense$578,251 $576,960 0.2% Our effective tax rates for the years ended December 31, 2016 and 2015 were 21.3% and 18.4%, respectively. Our 2016 effective tax rate differs fromthe U.S. federal statutory tax rate of 35%, due to lower international tax rates, partially offset by the non-deductible impairment charge for goodwill of $940.7million related to OpenTable recognized in 2016 (see Note 9 to the Consolidated Financial Statements) and the non-deductible impairment of our cost-method investment in Hotel Urbano recognized in 2016 (see Note 4 to the Consolidated Financial Statements). Our 2015 effective tax rate differed from theU.S. federal statutory rate as a result of lower international tax rates, partially offset by U.S. state income taxes.The non-deductible impairment charges referred to above have caused our effective tax rate to be higher for the year ended December 31, 2016compared to the year ended December 31, 2015. The increase has been partially offset by the favorable impact of an increased proportion of our incomebeing taxed at lower international tax rates due to the growth of our international businesses and the tax benefits recorded in 2016 arising from U.S. state taxlaw changes resulting in a net decrease to deferred tax liabilities, mostly associated with acquired intangible assets.A portion of Booking.com's earnings during the years ended December 31, 2016 and 2015 qualified for Innovation Box Tax treatment, which had asignificant beneficial impact on the Company's effective tax rate for those periods. While we expect Booking.com to continue to qualify for Innovation BoxTax treatment with respect to a portion of its earnings for the foreseeable future, the loss of the Innovation Box Tax benefit, whether due to a change in taxlaw or a determination by the Dutch government that Booking.com's activities are not "innovative" or for any other reason, would substantially increase oureffective tax rate and adversely impact our results of operations. See Part I Item 1A Risk Factors - "We may not be able to maintain our 'Innovation Box Tax'benefit."Until our U.S. net operating loss carryforwards are utilized or expire, most of our U.S. income will not be subject to a cash tax liability, other thanU.S. federal alternative minimum tax and state income taxes. However, we expect to pay foreign taxes on our international income except in countries wherewe have net operating loss carryforwards. We expect that our international operations will grow their pretax income faster than our U.S. businesses over thelong term and, therefore, it is our expectation that our cash tax payments will increase as our international businesses generate an increasing share of ourpretax income and as our U.S. net operating loss carryforwards are utilized or expire.47 As of December 31, 2016, we held approximately $12.6 billion of cash, cash equivalents, short-term investments and long-term investments outsideof the United States. We intend to indefinitely reinvest the earnings of our international subsidiaries outside of the United States. If that intention changesand we decide to repatriate that cash to the United States, whether due to cash needs in the United States or otherwise, we would incur related U.S. income taxexpense, but we would only make income tax payments when we repatriate the cash. We would pay only U.S. federal alternative minimum tax and U.S. stateincome taxes as long as we have net operating loss carryforwards available to offset our U.S. taxable income. As of December 31, 2016, we had net operatingloss carryforwards of $727.8 million and $583.9 million for U.S. federal and state tax purposes, respectively. If our foreign earnings were repatriated, we couldbe subject to a cash income tax liability on the earnings of our U.S. businesses sooner than would otherwise have been the case.

We believe that unitgrowth rates and total gross bookings and gross profit growth on a constant-currency basis, each of which exclude the impact of foreign exchange ratefluctuations, are important measures to understand the fundamental performance of the business.Agency gross bookings are derived from travel-related transactions where we do not facilitate payments for the travel services provided. Agencygross bookings increased 11.8% for the year ended December 31, 2015, compared to the year ended December 31, 2014, primarily due to growth in grossbookings from Booking.com agency accommodation room night reservations, as well as growth in gross bookings by priceline.com and Rentalcars.comagency retail rental car reservation services, and priceline.com and agoda.com agency retail hotel reservation services, partially offset by lower retail airfares.Merchant gross bookings are derived from services where we facilitate payments for the travel services provided. Merchant gross bookings increased2.0% for the year ended December 31, 2015, compared to the year ended December 31, 2014, primarily due to increases in gross bookings by merchant retailhotel reservation services for Booking.com and priceline.com, Rentalcars.com's rental car reservation service, and priceline.com's Express Deals® hotelreservation service as well as the inclusion of our Rocketmiles hotel reservation service since its acquisition in February 2015. These increases were partiallyoffset by declines in gross bookings by priceline.com's Name Your Own Price® reservation services and the impact of the stronger U.S. Dollar on agoda.com'smerchant retail hotel reservation service. The U.S. Dollar was significantly stronger against the Euro and many other currencies throughout 2015 compared to2014, which significantly adversely affected the growth of our agency and merchant gross bookings, expressed in U.S. Dollars.Accommodation room nights, rental car days and airline tickets reserved through our services for the years ended December 31, 2015 and 2014 wereas follows:Year Ended December 31, (in millions) 2015 2014 ChangeRoom Nights432.3 346.0 24.9 %Rental Car Days59.9 51.8 15.6 %Airline Tickets7.7 7.8 (1.6)% Accommodation room night reservations increased by 24.9% for the year ended December 31, 2015, compared to the year ended December 31,2014, due to an increase in Booking.com, agoda.com and priceline.com accommodation room night reservations and the inclusion of Rocketmilesaccommodation room night reservations since its acquisition in February 2015. Booking.com included over 850,000 properties on its website as of February15, 2016, which included approximately 390,000 vacation rental properties (updated property counts are available on the Booking.com website), comparedto over 635,000 properties (including approximately 269,000 vacation rental properties) a year ago. In September 2015, Booking.com changed the way itcalculates property counts. As a result, properties that are contracted with Booking.com but temporarily do not have availability on Booking.com (forexample properties that are closed during their off-peak season or for renovations) will remain49 included in Booking.com's property counts during these temporary periods. Booking.com previously excluded properties that were temporarily unavailablefor booking. We believe that continuously including them provides a more consistent and useful property count.Rental car day reservations increased by 15.6% for the year ended December 31, 2015, compared to the year ended December 31, 2014, due to anincrease in price-disclosed rental car day reservations for Rentalcars.com and priceline.com, partially offset by a decline in priceline.com's Name Your OwnPrice® rental car day reservations.Airline ticket reservations decreased by 1.6% for the year ended December 31, 2015, compared to the year ended December 31, 2014, due to adecline in priceline.com's Name Your Own Price® airline ticket reservations.

The U.S. Dollar was significantly stronger against the Euro and many other currencies throughout 2015 compared to 2014,which significantly adversely affected the growth of our agency revenues, expressed in U.S. Dollars.Merchant RevenuesMerchant revenues for the year ended December 31, 2015 decreased 4.7% compared to the year ended December 31, 2014, primarily due todecreases in revenues from priceline.com's Name Your Own Price® hotel, airline ticket and rental car reservation services, partially offset by increases in ourmerchant price-disclosed hotel and rental car businesses. Our priceline.com Name Your Own Price® reservation services, which declined year-over-year, arerecorded "gross" with a corresponding travel service provider cost recorded in cost of revenues. Our other merchant revenues, which in total grew year-over-year, are recorded in revenue "net" of travel service provider costs. As a result, changes in Name Your Own Price® reservation revenue disproportionatelyaffect merchant revenues as compared to our other merchant revenues. The U.S. Dollar was significantly stronger against the Euro and many other currenciesthroughout 2015 compared to 2014, which significantly adversely affected the growth of our merchant revenues, expressed in U.S. Dollars.Advertising and Other RevenuesAdvertising and other revenues during the year ended December 31, 2015 consisted primarily of advertising revenues, restaurant reservationrevenues and subscription revenues for restaurant reservation management services. Advertising and other revenues for the year ended December 31, 2015increased 49.5% compared to the year ended December 31, 2014, primarily as a result of the inclusion of a full year of OpenTable revenues in 2015 comparedto only a partial year's results in 2014, as well as growth in our KAYAK business. Cost of Revenues Year Ended December 31, (in thousands) 2015 2014 ChangeCost of Revenues$632,180 $857,841 (26.3)% 50 For the year ended December 31, 2015, cost of revenues consisted primarily of: (1) the cost paid to travel service providers for priceline.com's NameYour Own Price® and vacation package reservation services, net of applicable taxes and charges; and (2) fees paid to third parties by KAYAK andpriceline.com to return travel itinerary information for consumer search queries. Cost of revenues for the year ended December 31, 2015 decreased by 26.3%,compared to the year ended December 31, 2014, primarily due to a decrease in priceline.com's Name Your Own Price® reservation services. For the yearended December 31, 2015, cost of revenue benefited from a reversal of previously accrued travel transaction taxes of $16.4 million (including estimatedinterest and penalties) recorded in the first quarter of 2015 related to a favorable ruling in the State of Hawaii. In addition, for the year ended December 31,2015, we recognized a net reduction in cost of revenue in the third quarter of 2015 of $13.7 million related to travel transaction taxes, principally due to acash refund from the State of Hawaii for the aforementioned favorable ruling.Agency revenues have no cost of revenue.Gross Profit Year Ended December 31, (in thousands) 2015 2014 ChangeGross Profit$8,591,807 $7,584,130 13.3%Gross Margin93.1% 89.8% Total gross profit for the year ended December 31, 2015 increased by 13.3% compared to the year ended December 31, 2014 (growth on a constant-currency basis was approximately 27%), primarily as a result of the increased revenue discussed above. Total gross margin (gross profit as a percentage oftotal revenue) increased during the year ended December 31, 2015, compared to the year ended December 31, 2014, because our revenues aredisproportionately affected by priceline.com's Name Your Own Price® reservation services. Name Your Own Price® revenues are recorded "gross" with acorresponding travel service provider cost recorded in cost of revenues, and in the year ended December 31, 2015 these revenues represented a smallerpercentage of total revenues than in the year ended December 31, 2014. Our price-disclosed reservation services, which are recorded in revenue "net" of travelservice provider costs, have been growing faster than priceline.com's Name Your Own Price® reservation services. As a result, we believe that gross profit is animportant measure for evaluating growth in our business.Our international operations accounted for approximately $7.4 billion of our gross profit for the year ended December 31, 2015, compared to $6.6billion for the year ended December 31, 2014. Gross profit attributable to our international operations increased by 11.6% for the year ended December 31,2015 compared to the year ended December 31, 2014 (growth on a constant-currency basis was approximately 28%). Gross profit attributable to our U.S.businesses increased by 25.0% for the year ended December 31, 2015, compared to the year ended December 31, 2014. Gross profit for the year endedDecember 31, 2015 was positively impacted by the inclusion of OpenTable, which benefited year-over-year comparisons through the anniversary of theacquisition on July 24, 2015. In addition, gross profit for the year ended December 31, 2015 was positively impacted by a reversal of previously accruedtravel transaction taxes of $16.4 million (including estimated interest and penalties) recorded in the first quarter of 2015 related to a favorable ruling in theState of Hawaii. Gross profit for the year ended December 31, 2015 was also positively impacted by a net reduction in cost of revenue in the third quarter of2015 of $13.7 million related to travel transaction taxes, principally due to a cash refund from the State of Hawaii for the aforementioned favorable ruling.The U.S. Dollar was significantly stronger against the Euro and many other currencies throughout 2015 compared to 2014. At these exchange rates,the growth of our total and international gross bookings, expressed in U.S. Dollars, was significantly adversely impacted in 2015.51 Operating Expenses Advertising Year Ended December 31, (in thousands) 2015 2014 ChangePerformance Advertising$2,738,218 $2,334,453 17.3%% of Total Gross Profit31.9% 30.8% Brand Advertising$273,704 $257,077 6.5%% of Total Gross Profit3.2% 3.4% Performance advertising expenses consist primarily of the costs of (1) search engine keyword purchases; (2) referrals from meta-search and travelresearch websites; (3) affiliate programs; and (4) banner, pop-up and other Internet and mobile advertisements. For the year ended December 31, 2015,performance advertising expenses increased 17.3%, compared to the year ended December 31, 2014, primarily due to increased spending on onlineperformance marketing to generate increased gross bookings. Performance advertising as a percentage of gross profit for the year ended December 31, 2015benefited from the inclusion of OpenTable because OpenTable spends a lower percentage of gross profit on performance advertising relative to our otherbrands. In addition, the share of our business coming directly to our websites with no associated performance advertising expense increased during the yearended December 31, 2015 compared to the year ended December 31, 2014. These favorable impacts were more than offset for the year ended December 31,2015 by a year-over-year decline in advertising ROIs.Brand advertising expenses are primarily related to our Booking.com, KAYAK and priceline.com businesses and primarily consist of televisionadvertising. For the year ended December 31, 2015, brand advertising increased 6.5% compared to the year ended December 31, 2014, primarily due toincreased online video and television advertising, including associated production costs, at Booking.com, partially offset by lower television advertising atKAYAK and, to a lesser extent, priceline.com.Sales and Marketing Year Ended December 31, (in thousands) 2015 2014 ChangeSales and Marketing$353,221 $310,910 13.6%% of Total Gross Profit4.1% 4.1% Sales and marketing expenses consist primarily of (1) credit card and other payment processing fees associated with merchant transactions; (2) feespaid to third parties that provide call center, website content translations and other services; (3) customer relations costs; (4) public relations costs; (5)provisions for bad debt, primarily related to agency accommodation commission receivables; and (6) provisions for customer chargebacks. For the year endedDecember 31, 2015, sales and marketing expenses, which are substantially variable in nature, increased compared to the year ended December 31, 2014 dueprimarily to increased gross booking volumes, customer relations costs and the inclusion of a full year of OpenTable's results as compared to only a partialyear's results in 2014.Personnel Year Ended December 31, (in thousands) 2015 2014 ChangePersonnel$1,166,226 $950,191 22.7%% of Total Gross Profit13.6% 12.5% 52 Personnel expenses consist of compensation to our personnel, including salaries, stock-based compensation, bonuses, payroll taxes and employeehealth benefits. Personnel expenses increased during the year ended December 31, 2015, compared to the year ended December 31, 2014, due primarily toincreased headcount to support the growth of our businesses. Additionally, the inclusion of a full year of OpenTable's results in our 2015 consolidated resultsas compared to only a partial year's results in 2014 contributed to the increase in personnel expenses for the year ended December 31, 2015 compared to theyear ended December 31, 2014.General and Administrative Year Ended December 31, (in thousands) 2015 2014 ChangeGeneral and Administrative$415,420 $352,869 17.7%% of Total Gross Profit4.8% 4.7% General and administrative expenses consist primarily of: (1) occupancy and office expenses; (2) personnel-related expenses such as travel,recruiting and training expenses; and (3) fees for outside professionals, including litigation expenses.

Additionally, the inclusion of afull year of OpenTable's results in our 2015 consolidated results as compared to only a partial year's results in 2014 contributed to the increase in general andadministrative expenses for the year ended December 31, 2015 compared to the year ended December 31, 2014.Information TechnologyYear Ended December 31, (in thousands) 2015 2014 ChangeInformation Technology$113,617 $97,498 16.5%% of Total Gross Profit1.3% 1.3% Information technology expenses consist primarily of: (1) software license and system maintenance fees; (2) data communications and otherexpenses associated with operating our services; (3) outsourced data center costs; and (4) payments to outside consultants.

For the year ended December 31, 2015, depreciation and amortization expense increased, compared to the year ended December 31, 2014,due primarily to increased intangible amortization from the OpenTable acquisition and increased depreciation expense due to capital expenditures foradditional data center capacity and office build-outs to support growth and geographic expansion, principally related to our Booking.com53 business. Additionally, the inclusion of OpenTable in our consolidated results since its acquisition on July 24, 2014 contributed to the increase indepreciation expense for the year ended December 31, 2015 compared to the year ended December 31, 2014.Other Income (Expense) Year Ended December 31, (in thousands) 2015 2014 ChangeInterest Income$55,729 $13,933 300.0%Interest Expense(160,229) (88,353) 81.4%Foreign Currency Transactions and Other(26,087) (9,444) 176.2%Total$(130,587) $(83,864) 55.7% For the year ended December 31, 2015, interest income on cash and marketable securities increased compared to the year ended December 31, 2014,primarily due to an increase in the average invested balance and higher yields. Interest expense increased for the year ended December 31, 2015, compared tothe year ended December 31, 2014, primarily due to interest expense attributable to our Senior Notes issued in August 2014, September 2014, March 2015and November 2015, partially offset by the maturity of our 1.25% Convertible Senior Notes in March 2015. See Note 10 to our Consolidated FinancialStatements.Derivative contracts that hedge our exposure to the impact of currency fluctuations on the translation of our international operating results into U.S.Dollars upon consolidation resulted in foreign exchange losses of $6.6 million for the year ended December 31, 2015 compared to foreign exchange gains of$13.7 million for the year ended December 31, 2014, and are recorded in "Foreign currency transactions and other" in the Consolidated Statements ofOperations.Foreign exchange transaction losses, including costs related to foreign exchange transactions, resulted in losses of $21.0 million for the year endedDecember 31, 2015, which includes approximately $5.7 million of hedging cost and a foreign exchange loss recorded in the fourth quarter of 2015 related tothe devaluation of the Argentine Peso, compared to foreign exchange losses of $17.6 million for the year ended December 31, 2014, and are recorded in"Foreign currency transactions and other" in the Consolidated Statements of Operations.For the year ended December 31, 2015, we recognized $2.2 million of net realized gains related to investments, which are recorded in "Foreigncurrency transactions and other" in the Consolidated Statement of Operations.The conversion of our convertible debt prior to maturity in the year ended December 31, 2014 resulted in non-cash losses of $6.3 million, which arerecorded in "Foreign currency transactions and other" in the Consolidated Statement of Operations.Income Taxes Year Ended December 31, (in thousands) 2015 2014 ChangeIncome Tax Expense$576,960 $567,695 1.6% Our effective tax rates for the years ended December 31, 2015 and 2014 were 18.4% and 19.0%, respectively. Our effective tax rate differs from theU.S. federal statutory tax rate of 35%, due to lower tax rates outside the United States, partially offset by U.S. state income taxes and certain non-deductibleexpenses. Our effective tax rate was lower for the year ended December 31, 2015, compared to the year ended December 31, 2014, due to an increasedproportion of our income being taxed at lower international tax rates. A portion of Booking.com's earnings during the year ended December 31, 2015 and2014 qualified for Innovation Box Tax treatment, which had a significant beneficial impact on the Company's effective tax rate for those periods.54 Liquidity and Capital Resources As of December 31, 2016, we had $13.9 billion in cash, cash equivalents, short-term investments and long-term investments. Approximately $12.6billion is held by our international subsidiaries and is denominated primarily in U.S. Dollars, Euros and, to a lesser extent, British Pounds Sterling and othercurrencies.

At December 31, 2016, wehad approximately $13.0 billion cumulative unremitted international earnings. We estimate that the deferred tax liability we would record if such earningswere not indefinitely reinvested internationally is approximately $2.3 billion as of December 31, 2016. If we repatriate cash to the United States, we wouldutilize our net operating loss carryforwards and beyond that amount incur additional tax payments in the United States.In May 2016, we issued Senior Notes due June 1, 2026, with an interest rate of 3.6% (the "2026 Notes") for an aggregate principal amount of $1.0billion. Interest on the 2026 Notes is payable semi-annually on June 1 and December 1, beginning December 1, 2016. The net proceeds of these notes may beused for general corporate purposes, which may include share repurchases, repayment of debt and acquisitions. See Note 10 to the Consolidated FinancialStatements for further details on the 2026 Notes.In June 2015, we entered into a $2.0 billion five-year unsecured revolving credit facility with a group of lenders. Borrowings under the revolvingcredit facility will bear interest, at our option, at a rate per annum equal to either (i) the adjusted LIBOR for the interest period in effect for such borrowingplus an applicable margin ranging from 0.875% to 1.50%; or the greatest of (a) Bank of America, N.A.'s prime lending rate, (b) the federal funds rate plus0.5%, and (c) an adjusted LIBOR for an interest period of one month plus 1.00%, plus an applicable margin ranging from 0.00% to 0.50%. Undrawn balancesavailable under the revolving credit facility are subject to commitment fees at the applicable rate ranging from 0.085% to 0.20%. The revolving creditfacility provides for the issuance of up to $70.0 million of letters of credit as well as borrowings of up to $50.0 million on same-day notice, referred to asswingline loans. Borrowings under the revolving credit facility may be made in U.S. Dollars, Euros, British Pounds Sterling and any other foreign currencyagreed to by the lenders. The proceeds of loans made under the facility will be used for working capital and general corporate purposes. As of December 31,2016, there were no borrowings outstanding and approximately $3.8 million of letters of credit issued under the facility.Our Convertible Senior Notes due March 15, 2018, with an interest rate of 1.0% (the "2018 Notes"), are convertible at the option of the holders as ofDecember 31, 2016, and, accordingly, we reported the carrying value of the 2018 Notes as a current liability in our Consolidated Balance Sheet as ofDecember 31, 2016. We have received a notice for conversion of $3 thousand aggregate principal amount for the 2018 Notes through February 24, 2017. Ifnote holders exercise their option to convert, we would be required to repay the principal amount of the 2018 Notes in cash and may deliver shares ofcommon stock or cash, at our option, to satisfy the conversion value in excess of the principal amount. We may borrow under the revolving credit facility tosatisfy our obligation.In September 2016, we invested $25 million in a Ctrip six-year senior convertible note issued at par value and $25 million in Ctrip ordinary shares.In September 2016, we signed a turnkey agreement to construct an office building in the Netherlands for the future headquarters of Booking.com forapproximately 270 million Euros. Upon signing the agreement, we paid approximately 48 million Euros to the developer, principally related to acquiredland use rights, and we expect to pay approximately 34 million Euros related to building construction during 2017, with the remainder of payments beingpaid periodically beginning in 2018 until the expected completion of the building in late 2020. We will also incur capital expenditures to fit out and furnishthe office space. We utilized international cash for the September 2016 payment and we expect all future payments to be made from international cash. SeeNote 14 to the Consolidated Financial Statements.During the year ended December 31, 2016, we repurchased 762,984 shares of our common stock for an aggregate cost of $1.0 billion, which includesstock repurchases in December 2016 of 10,215 shares for an aggregate cost of $15.0 million that were settled in January 2017. As of December 31, 2016, theCompany had a remaining authorization of $2.1 billion to purchase its common stock. In the first quarter of 2017, the Board of Directors authorized aprogram to repurchase up to $2.0 billion of our common stock, in addition to amounts previously authorized. We may from time to time make additionalrepurchases of our common stock, depending on prevailing market conditions, alternate uses of capital and other factors. We55 may use cash-on-hand and cash generated by our operations in the United States to fund our share repurchases. We may also utilize our revolving creditfacility or raise funds through the debt capital markets to fund share repurchases.On February 7, 2017, we signed a definitive agreement to acquire the Momondo Group. We will use approximately $550 million of our internationalcash to fund this acquisition. The deal is expected to close later in the year, subject to regulatory approval. Our merchant transactions are structured such that we collect cash up front from consumers and then we pay most of our travel service providers at asubsequent date. We therefore tend to experience significant swings in accounts receivable, deferred merchant bookings and travel service provider payablesseasonally depending on the absolute level of our merchant transactions during the last few weeks of every quarter.Net cash provided by operating activities for the year ended December 31, 2016, was $3.9 billion, resulting from net income of $2.1 billion, afavorable impact of $1.6 billion for non-cash items not affecting cash flows and net favorable changes in working capital and other assets and liabilities of$215.9 million.

Cash provided by financing activities for theyear ended December 31, 2016 primarily consisted of net proceeds of $994.7 million from the issuance of Senior Notes, excess tax benefits on stock-basedawards and other equity deductions of $61.0 million and the exercise of employee stock options of $15.6 million, partially offset by treasury stock purchasesof $1.0 billion. Net cash used in financing activities was $730.0 million for the year ended December 31, 2015. Cash used in financing activities for the yearended December 31, 2015 primarily consisted of treasury stock purchases of $3.1 billion, payments of $147.6 million related to56 the conversion of Senior Notes and payment of $10.7 million related to the settlement of the acquisition-date estimated contingent liability related to anacquisition, primarily offset by the total proceeds of $2.4 billion from the issuance of Senior Notes, excess tax benefits on stock-based awards of $101.5million and the exercise of employee stock options of $20.9 million. Net cash provided by financing activities was approximately $1.4 billion for the yearended December 31, 2014. Cash provided by financing activities for the year ended December 31, 2014 primarily consisted of total proceeds of $2.3billion from the issuance of Convertible Senior Notes and Euro denominated Senior Notes, excess tax benefits on stock-based awards of $23.4 million andthe exercise of employee stock options of $16.4 million, partially offset by treasury stock purchases of $750.4 million and payments of $125.1million related to the conversion of Senior Notes.ContingenciesFrench tax authorities recently concluded an audit that started in 2013 of the years 2003 through 2012 to determine whether Booking.com is incompliance with its tax obligations in France. Booking.com received formal assessments in December 2015 in which the French tax authorities claim thatBooking.com has a permanent establishment in France and seek to recover unpaid income taxes and value-added taxes of approximately 356 million Euros,the majority of which would represent penalties and interest. We believe that Booking.com has been, and continues to be, in compliance with French tax lawand we intend to contest the assessments. If we are unable to resolve the matter with the French authorities, we would expect to challenge the assessments inthe French courts. In order to contest the assessments in court, we may be required to pay, upfront, the full amount or a significant part of any suchassessments, though any such payment would not constitute an admission by us that we owe the taxes. At the end of 2016, French authorities announcedtheir intention to also audit the tax years 2013 to 2015, which could result in additional assessments. See Part I Item IA Risk Factors - "We may have exposureto additional tax liabilities."A number of U.S. jurisdictions have initiated lawsuits against online travel companies, including us, related to, among other things, the payment oftravel transaction taxes (e.g., hotel occupancy taxes, excise taxes, sales taxes, etc.). In addition, a number of U.S. states, counties and municipalities haveinitiated audit proceedings, issued proposed tax assessments or started inquiries relating to the payment of travel transaction taxes. For additionalinformation, see Note 14 to the Consolidated Financial Statements and Part I Item 1A Risk Factors - "Adverse application of U.S. state and local tax lawscould have an adverse effect on our business and results of operations." in this Annual Report.As a result of this litigation and other attempts by U.S. jurisdictions to levy similar taxes, we have established an accrual (including estimatedinterest and penalties) for the potential resolution of issues related to travel transaction taxes in the amount of approximately $27 million as of bothDecember 31, 2016 and 2015. The accrual is based on our estimate of the probable cost of resolving these issues. Our legal expenses for these matters areexpensed as incurred and are not reflected in the amount accrued. The actual cost may be less or greater, potentially significantly, than the liabilitiesrecorded. An estimate for a reasonably possible loss or range of loss in excess of the amount accrued cannot be reasonably made. If we were to suffer adversedeterminations in the near term in more of the pending proceedings than currently anticipated given results to date, because of our available cash we believethat it would not have a material impact on our liquidity.The following table represents our material contractual obligations and commitments as of December 31, 2016: Payments due by Period (in thousands)Contractual Obligations Total Less than1 Year 1 to 3Years 3 to 5 Years More than 5 YearsOperating lease obligations(1) $523,820 $102,339 $193,885 $134,124 $93,472Land lease obligation(1) 63,851 1,317 2,633 2,633 57,268Building construction obligation(1) 233,385 34,860 136,516 62,009 —Senior Notes(2) 8,481,228 137,794 1,260,587 2,250,337 4,832,510Revolving credit facility(3) 9,447 3,188 5,075 1,184 —Earnout - acquisition 9,170 — 9,170 — —Total(4) $9,320,901 $279,498 $1,607,866 $2,450,287 $4,983,250(1)See the section on "Operating Leases" and "Building Construction" section of Note 14 to the Consolidated Financial Statements for more details.(2)Represents the aggregate principal amount of our Senior Notes outstanding as of December 31, 2016 and cumulative interest to maturity of $1.1 billion. Convertible debt does not reflect the market value in excess of the outstanding57 principal amount because we can settle the conversion premium amount in cash or shares of common stock at our option. See Note 10 to theConsolidated Financial Statements.(3)Represents fees on uncommitted funds and outstanding letters of credit as of December 31, 2016.(4)We reported "Other long-term liabilities" of $139 million on the Consolidated Balance Sheet at December 31, 2016, of which approximately $53 millionrelated to deferred rents, approximately $30 million related to unrecognized tax benefits (see Note 13 to the Consolidated Financial Statements) andapproximately $27 million related to our accrual for the potential resolution of issues related to travel transaction taxes (see Note 14 to the ConsolidatedFinancial Statements). A variety of factors could affect the timing of payments for the liabilities related to travel transaction taxes and unrecognized taxbenefits. We believe that these matters will likely not be resolved in the next twelve months and accordingly we have classified the estimated liability asnon-current in the Consolidated Balance Sheet. Therefore, we have excluded long-term liabilities of $130 million from the contractual obligations tableabove because we cannot reasonably estimate the timing of such payments or the liability is related to deferred rents, which represents the difference inrent expense recognized in the income statements and rent payments related to operating leases.We believe that our existing cash balances and liquid resources will be sufficient to fund our operating activities, capital expenditures and otherobligations through at least the next twelve months. However, if during that period or thereafter, we are not successful in generating sufficient cash flow fromoperations or in raising additional capital when required in sufficient amounts and on terms acceptable to us, we may be required to reduce our plannedcapital expenditures and scale back the scope of our business plan, either of which could have a material adverse effect on our future financial condition orresults of operations. If additional funds were raised through the issuance of equity securities, the percentage ownership of our then current stockholderswould be diluted. We may not generate sufficient cash flow from operations in the future, revenue growth or sustained profitability may not be realized, andfuture borrowings or equity sales may not be available in amounts sufficient to make anticipated capital expenditures, finance our strategies or repay ourindebtedness. Off-Balance Sheet Arrangements. As of December 31, 2016, we did not have any off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect onour financial condition, results of operations, liquidity, capital expenditures or capital resources.Item 7A. Quantitative and Qualitative Disclosures About Market Risk We manage our exposure to interest rate risk and foreign currency risk through internally established policies and procedures and, when deemedappropriate, through the use of derivative financial instruments. We use currency exchange derivative contracts to manage short-term foreign currency risk.The objective of our policies is to mitigate potential income statement, cash flow and fair value exposures resulting from possible future adversefluctuations in rates. We evaluate our exposure to market risk by assessing the anticipated near-term and long-term fluctuations in interest rates and foreignexchange rates. This evaluation includes the review of leading market indicators, discussions with financial analysts and investment bankers regardingcurrent and future economic conditions and the review of market projections as to expected future rates. We utilize this information to determine our owninvestment strategies as well as to determine if the use of derivative financial instruments is appropriate to mitigate any potential future market exposure thatwe may face. Our policy does not allow speculation in derivative instruments for profit or execution of derivative instrument contracts for which there are nounderlying exposures. We do not use financial instruments for trading purposes and are not a party to any leveraged derivatives. To the extent that changes ininterest rates and currency exchange rates affect general economic conditions, we would also be affected by such changes.We did not experience any material changes in interest rate exposures during the year ended December 31, 2016. Based upon economic conditionsand leading market indicators at December 31, 2016, we do not foresee a significant adverse change in interest rates in the near future.Fixed rate investments are subject to unrealized gains and losses due to interest rate volatility. We performed a sensitivity analysis to determine theimpact a change in interest rates would have on the fair value of our available-for-sale investments assuming an adverse change of 100 basis points. As ofDecember 31, 2016, a hypothetical 100 basis point (1.0%) increase in interest rates would have resulted in a decrease in the fair values of our investments indebt securities by approximately $204 million. These hypothetical losses would only be realized if we sold the investments prior to their maturity. Thisamount excludes our investment in Ctrip.com International Ltd. ("Ctrip") senior convertible notes, which are also subject to market price risk, which couldpotentially have a more significant impact on the change in fair value. The fair58 value of our Ctrip senior convertible notes will likely increase as the market price of Ctrip's American Depositary Shares ("ADSs") increase and decrease as theprice of Ctrip's ADSs fall.As of December 31, 2016, the outstanding aggregate principal amount of our debt was approximately $7.4 billion. We estimate that the market valueof such debt was approximately $8.4 billion as of December 31, 2016. A substantial portion of the market value of our debt in excess of the outstandingprincipal amount is related to the conversion premium on our outstanding convertible notes.We conduct a significant portion of our business outside the United States through subsidiaries with functional currencies other than the U.S. Dollar(primarily Euros). As a result, we face exposures to adverse movements in currency exchange rates as the operating results of our international operations aretranslated from local currencies into U.S. Dollars upon consolidation. If the U.S. Dollar weakens against the local currencies, the translation of these foreign-currency-denominated balances will result in increased net assets, gross bookings, gross profit, operating expenses, and net income. Similarly, our net assets,gross bookings, gross profit, operating expenses, and net income will decrease if the U.S. Dollar strengthens against the local currency. Additionally, foreignexchange rate fluctuations on transactions, denominated in currencies other than the functional currency, result in gains and losses that are reflected in theConsolidated Statements of Operations.Throughout 2015, the U.S. Dollar strengthened significantly year-over-year relative to substantially all currencies in which we transact, mostnotably the Euro, Brazilian Real, British Pound Sterling, Russian Ruble and Australian Dollar. In 2016, the U.S. Dollar continued to be stronger year-over-year relative to the British Pound Sterling, Russian Ruble and many other major currencies in which we transact. Since the “Brexit” referendum in the UnitedKingdom in June 2016, the U.S. Dollar has strengthened significantly against the British Pound Sterling. As a result of these currency exchange rate changes,our foreign currency denominated net assets, gross bookings, gross profit, operating expenses and net income have been negatively impacted as expressed inU.S. Dollars, although to a much lesser extent in 2016 than in 2015. Since our expenses are generally denominated in foreign currencies on a basis similar toour revenues, our operating margins are not significantly impacted by currency fluctuations. The aggregate principal value of our Euro-denominated 2022Notes, 2024 Notes and 2027 Notes, and accrued interest thereon, provide a natural hedge of the net assets of certain of our Euro functional currencysubsidiaries.From time to time, we enter into foreign exchange derivative contracts to minimize the impact of short-term foreign currency fluctuations in ourconsolidated operating results. Our derivative contracts principally address foreign exchange fluctuation risk for the Euro, the British Pound Sterling andcertain other currencies versus the U.S. Dollar. As of December 31, 2016 and 2015, there were no such outstanding derivative contracts. Foreign exchangegains of $3.4 million for the year ended December 31, 2016, foreign exchange losses of $6.6 million for the year ended December 31, 2015 and foreignexchange gains of $13.7 million for the year ended December 31, 2014 were recorded in "Foreign currency transactions and other" in the ConsolidatedStatements of Operations.Item 8.

Under the supervision and with the participation of our management, including our principal executive officerand our principal financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Exchange Act Rule13a-15(e). Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedureswere effective as of the end of the period covered by this Annual Report on Form 10-K.59 Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, we include a report of our management's assessment of the design and effectiveness ofour internal controls over financial reporting for the year ended December 31, 2016.Management's Report on Internal Control Over Financial Reporting. Our management is responsible for establishing and maintaining adequateinternal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of ourmanagement, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal controlover financial reporting based on the framework in the Internal Control - Integrated Framework (2013) issued by the Committee of SponsoringOrganizations of the Treadway Commission.Based on our evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2016. Ourindependent registered public accounting firm also attested to, and reported on the effectiveness of internal control over financial reporting.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluationof effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree ofcompliance with the policies or procedures may deteriorate.Changes in Internal Controls. No change in our internal control over financial reporting (as such term is defined in Exchange Act Rule 13a-15(f))occurred during the three months ended December 31, 2016 that materially affected, or is reasonably likely to materially affect, our internal control overfinancial reporting.60 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Stockholders ofThe Priceline Group Inc.Norwalk, Connecticut We have audited the internal control over financial reporting of The Priceline Group Inc. and subsidiaries (the "Company") as of December 31, 2016,based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the TreadwayCommission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of theeffectiveness of internal control over financial reporting, included in the accompanying "Management's Report on Internal Control Over FinancialReporting" appearing in Item 9A. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standardsrequire that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained inall material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weaknessexists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures aswe considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive andprincipal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel toprovide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordancewith generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertainto the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generallyaccepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of managementand directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or dispositionof the company's assets that could have a material effect on the financial statements. Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper managementoverride of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation ofthe effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because ofchanges in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, basedon the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the TreadwayCommission. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidatedfinancial statements as of and for the year ended December 31, 2016 of the Company and our report dated February 27, 2017 expressed an unqualifiedopinion on those financial statements. /s/ DELOITTE & TOUCHE LLP Stamford, ConnecticutFebruary 27, 2017 61 Item 9B.

("OpenTable") since its acquisition in July 2014. All intercompany accounts and transactions have been eliminatedin consolidation. Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States ofAmerica requires management to make estimates and assumptions that affect the amounts reported in the financial statements and footnotes thereto. Actualresults may differ significantly from those estimates. The estimates underlying the Company's Consolidated Financial Statements relate to, among otherthings, stock-based compensation, the allowance for doubtful accounts, the valuation of goodwill, long-lived assets and intangibles, income taxes, theaccrual for loyalty programs and the accrual for travel transaction taxes. Reclassifications — Certain amounts from prior periods have been reclassified to conform to the current year presentation.Fair Value of Financial Instruments — The Company's financial instruments, including cash, restricted cash, accounts receivable, accounts payable,accrued expenses and deferred merchant bookings, are carried at cost which approximates their fair value because of the short-term nature of these financialinstruments. See Notes 4, 5 and 10 for information on fair value for investments, derivatives, and the Company's outstanding Senior Notes. Cash and Cash Equivalents — Cash and cash equivalents consists primarily of cash and highly liquid investment grade securities with an originalmaturity of three months or less. Cash equivalents are recognized based on settlement date. Restricted Cash — Restricted cash at December 31, 2016 and 2015 collateralizes office leases. In 2016, the Company changed the presentation ofrestricted cash on the balance sheet to include it in "Prepaid expenses and other current assets." The Consolidated Balance Sheet as of December 31, 2015 wasadjusted to conform with this change.The following table shows a reconciliation of cash, cash equivalent and restricted cash reported in the Consolidated Balance Sheets to the totalamount shown in the Consolidated Statements of Cash Flows: December 31, 2016 2015 2014As included in the Consolidated Balance Sheets: Cash and cash equivalents $2,081,075 $1,477,265 $3,148,651Restricted cash 932 806 843Total cash, cash equivalents and restricted cash as shown in the Consolidated Statements of Cash Flows $2,082,007 $1,478,071 $3,149,49475 Investments — The Company has classified its investments in debt securities and equity securities with readily determinable fair value as available-for-sale securities. These securities are recognized based on trade date and carried at estimated fair value with the aggregate unrealized gains and lossesrelated to these investments, net of taxes, reflected as a part of "Accumulated other comprehensive income (loss)" within stockholders' equity. The fair value of the investments is based on the specific quoted market price of the securities or comparable securities at the balance sheet dates. Investments in debt securities are considered to be impaired when a decline in fair value is judged to be other than temporary because the Company eitherintends to sell or it is more-likely-than not that it will have to sell the impaired security before recovery. Once a decline in fair value is determined to be otherthan temporary, an impairment charge is recorded and a new cost basis in the investment is established. If the Company does not intend to sell the debtsecurity, but it is probable that the Company will not collect all amounts due, then only the impairment due to the credit risk would be recognized inearnings and the remaining amount of the impairment would be recognized in "Accumulated other comprehensive income (loss)" within stockholders' equity.Marketable securities are presented as current assets on the Company's Consolidated Balance Sheets if they are available to meet short-term working capitalneeds of the Company. Marketable debt securities not held to meet short-term working capital needs of the Company are classified as short-term or long-terminvestments on the Company's Consolidated Balance Sheets based on the maturity date of the debt security. See Notes 4 and 5 for further detail ofinvestments.Equity investments without readily determinable fair values, in companies over which the Company does not have the ability to exercise significantinfluence, are accounted for using the cost method of accounting and classified within "Other assets" in the Consolidated Balance Sheets. Under the costmethod, investments are carried at cost and are adjusted to fair value only for other-than-temporary declines in fair value.Property and Equipment — Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed on a straight-linebasis over the estimated useful lives of the assets or, when applicable, the life of the lease related to leasehold improvements, whichever is shorter.Building Construction-in-progress — Building construction-in-progress is associated with the construction of an office building in the Netherlandsand is included in “Property and equipment, net” in the Consolidated Balance Sheet at December 31, 2016. Depreciation of the building and its relatedcomponents will commence once it is ready for the Company’s use.Website and Internal-use Software Capitalization — Certain direct development costs associated with website and internal-use software arecapitalized and include external direct costs of services and payroll costs for employees devoting time to the software projects principally related to websiteand mobile app development, including support systems, software coding, designing system interfaces and installation and testing of the software. Thesecosts are recorded as property and equipment and are generally amortized over a period of two to five years beginning when the asset is substantially readyfor use. Costs incurred for enhancements that are expected to result in additional features or functionality are capitalized and amortized over the estimateduseful life of the enhancements. Costs incurred during the preliminary project stage, as well as maintenance and training costs, are expensed as incurred.Additions to capitalized costs during the years ended December 31, 2016, 2015 and 2014 were $54.2 million, $44.2 million and $20.9 million, respectively.Costs capitalized in 2016 were higher than in 2015 primarily related to activity for agoda.com. Costs for 2015 reflect a full year of activity for OpenTablecompared to a partial year's activity in 2014 and higher development costs for priceline.com. Land use rights — Land use rights represent prepayments for the lease of land where the Company is constructing an office building in theNetherlands. The land use rights are recorded as rent expense in "General and administrative" expense in the Consolidated Statement of Operations on astraight-line basis over the lease period. At December 31, 2016, the Company had approximately $45.3 million associated with land use rights recorded in“Other assets” in the Consolidated Balance Sheet. See Note 14 for further details.Goodwill — The Company accounts for acquired businesses using the purchase method of accounting which requires that the assets acquired andliabilities 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 thenet assets acquired is recorded as goodwill. The Company's Consolidated Financial Statements reflect an acquired business starting at the date of theacquisition. Goodwill is not subject to amortization and is reviewed at least annually for impairment, or earlier if an event occurs or circumstances change andthere is an indication of impairment. The Company tests goodwill at a reporting unit level. The fair value of the reporting unit is compared to its carryingvalue, including goodwill. Fair values are determined using a76 combination of standard valuation techniques, including an income approach (discounted cash flows) and market approaches (EBITDA multiples ofcomparable publicly-traded companies and precedent transactions) and based on market participant assumptions. An impairment is recorded to the extentthat the implied fair value of goodwill is less than the carrying value of goodwill. See Note 9 for further information.Impairment of Long-Lived Assets and Intangible Assets — The Company reviews long-lived assets and amortizable intangible assets for impairmentwhenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The assessment of possible impairment isbased upon the Company's ability to recover the carrying value of the assets from the estimated undiscounted future net cash flows, before interest and taxes,of the related operations. The amount of impairment loss, if any, is measured as the excess of the carrying value of the asset over the present value ofestimated future cash flows, using a discount rate commensurate with the risks involved and based on assumptions representative of market participants.Agency Revenues Agency revenues are derived from travel-related transactions where the Company does not facilitate payments for the travel services provided.Agency revenues consist primarily of accommodation reservation commissions, as well as certain global distribution system ("GDS") reservation bookingfees and travel insurance fees, and are reported at the net amounts received, without any associated cost of revenue. Such revenues are primarily recognizedby the Company when the customer's travel is completed.Merchant RevenuesMerchant revenues are derived from services where the Company facilitates payments for the travel services provided. Name Your Own Price® travelreservation services are presented in the income statement on a gross basis so merchant revenue and costs of revenues include the reservation price to thecustomer and the cost charged by the service provider, respectively. For all other merchant transactions, the Company presents merchant revenue on a netbasis in the income statement.Merchant revenue also includes ancillary fees, including damage excess waiver and travel insurance and certain GDS reservation booking fees,customer processing fees associated with priceline.com's opaque reservation services and merchant retail accommodation reservation services atpriceline.com and agoda.com and are generally recognized by the Company when the customer completes his/her travel.Merchant Retail Services: Merchant revenues for the Company's merchant retail services are derived from transactions where customers bookaccommodation reservations or rental car reservations from travel service providers at disclosed rates which are subject to contractual arrangements. TheCompany charges the customer at the time of booking and any amounts owed to the travel service provider along with the Company's deferred revenue areincluded in deferred merchant bookings. Reservations are generally refundable upon cancellation, subject to cancellation penalties in certain cases. Merchant revenue and the cost charged by travel service provider for priceline.com, agoda.com and Rentalcars.com are recognized when the customercompletes their travel. Revenue for Booking.com's merchant transactions is comprised of accommodation reservation commissions which are recognizedwhen the customer completes their travel.Merchant Opaque Services: The Company describes its priceline.com Name Your Own Price® and Express Deals® travel services as "opaque"because certain elements of the service, including the identity of the travel service provider, are not disclosed to the consumer prior to making a reservation.The Name Your Own Price® service connects consumers that are willing to accept a level of flexibility regarding their travel itinerary with travel serviceproviders that are willing to accept a lower price in order to sell their excess capacity without disrupting their existing distribution channels or retail pricingstructures. The Company's Name Your Own Price® services use a pricing system that allows consumers to "bid" the price they are prepared to pay whensubmitting an offer for a particular travel service. The Company accesses databases in which participating travel service providers file secure discountedrates, not generally available to the public, to determine whether it can fulfill the consumer's offer. The Company selects the travel service provider anddetermines the price it will accept from the consumer. Express Deals® allows consumers to select hotel, rental car and airline ticket reservations with price andcertain information regarding amenities disclosed prior to making the reservation. The Company recognizes revenues and costs for these services when itconfirms the customer's non-refundable offer. In circumstances where the Company makes certain customer concessions, the Company accrues for suchestimated losses. Pursuant to the terms of the Company's retail and opaque merchant services, its travel service providers are permitted to bill the Company for theunderlying cost of the service during a specified period of time. In the event that the Company is not billed by the travel provider within the specified timeperiod, the Company reduces its cost by the unbilled amounts.77 Advertising and Other RevenuesAdvertising and other revenues are primarily earned by KAYAK and OpenTable and to a lesser extent by priceline.com for advertising placementson its website and Booking.com's BookingSuite branded accommodation marketing and business analytics services. KAYAK earns advertising revenueprimarily by sending referrals to OTCs and travel service providers and from advertising placements on its websites and mobile apps. Revenue related toreferrals is earned when a customer clicks on a referral placement or upon completion of the travel. Revenue for advertising placements is earned based uponwhen a customer clicks on an advertisement or when KAYAK displays an advertisement. OpenTable earns reservation fees when diners are seated through itsonline restaurant reservation service and subscription fees for restaurant management services on a straight-line basis over the contractual period that theservice is provided.Cost of RevenuesCost of revenues consists primarily of the cost paid to travel service providers for priceline.com's Name Your Own Price® and vacation packagereservation services, net of applicable taxes and charges, and fees paid to third parties by KAYAK and priceline.com to return travel itinerary information forconsumer search queries.Loyalty ProgramsThe Company provides various loyalty programs. Participating customers earn loyalty points on current transactions that can be redeemed for futurequalifying transactions. When the points are earned, the Company estimates the amount of loyalty points expected to be redeemed and records a reduction inrevenue. At December 31, 2016 and 2015, a liability of $84.4 million and $71.1 million, respectively, for loyalty points programs was included in "Accruedexpenses and other current liabilities" in the Consolidated Balance Sheets.Tax Recovery Charge, Occupancy Taxes and State and Local Taxes The Company provides an online travel service to facilitate online travel purchases by consumers from travel service providers, includingaccommodation, rental car and airline ticket reservations, and sometimes as part of a vacation package reservation. For merchant transactions, the Companycharges the consumer an amount intended to cover the taxes that the Company anticipates the travel service provider will owe and remit to the local taxingauthorities ("tax recovery charge"). Tax rate information for calculating the tax recovery charge is provided to the Company by the travel service providers. In certain taxing jurisdictions, the Company is required by statute or court order to collect and remit certain taxes (local occupancy tax, generalexcise and/or sales tax) imposed upon its margin and/or service fee. The tax recovery charge and occupancy and other related taxes collected from customersand remitted to those jurisdictions are reported on a net basis in the Consolidated Statement of Operations. Except in those jurisdictions, the Company doesnot charge the customer or remit occupancy or other related taxes based on its margin or service fee (see Note 14).Performance Advertising — Advertising expenses classified as performance advertising are generally managed by the Company by monitoringreturn on investment. These expenses primarily consist of: (1) search engine keyword purchases; (2) referrals from meta-search and travel research websites;(3) affiliate programs; and (4) other performance-based advertisements. Performance advertising expense is recognized as incurred. Included in "Accruedexpenses and other current liabilities" in the Consolidated Balance Sheets are accrued performance advertising liabilities of $267.5 million and $188.2million at December 31, 2016 and 2015, respectively.Brand Advertising — Advertising expenses classified as brand advertising are generally managed by the Company to a targeted spending level todrive brand awareness. This includes both online and offline activities such as online videos (for example, on YouTube and Facebook), televisionadvertising, billboards and subway and bus advertisements. Brand advertising expense is generally recognized as incurred with the exception of advertisingproduction costs, which are expensed the first time the advertisement is displayed or broadcast.In 2016, the Company changed the presentation of advertising expenses from "Advertising - Online" and "Advertising - Offline" to "Performanceadvertising" and "Brand advertising" in the Consolidated Statements of Operations. This change in presentation had no impact on total advertising expenses,operating income or net income. As a result, for the years ended December 31, 2015 and 2014, brand advertising in online channels of $59.0 million and$25.8 million , respectively, is now recorded in "Brand advertising" rather than "Advertising - Online". The Company believes its new presentation is helpfulbecause it separates performance advertising that is typically managed on a return on investment basis from brand advertising78 that is generally spent to build brand awareness and managed to a targeted spending level. See above for the descriptions and accounting policies ofperformance advertising and brand advertising. Sales and Marketing — Sales and marketing expenses consist primarily of (1) credit card and other payment processing fees associated withmerchant transactions; (2) fees paid to third parties that provide call center, website content translations and other services; (3) customer relations costs; (4)public relations costs; (5) provisions for bad debt, primarily related to agency accommodation commission receivables; and (6) provisions for customerchargebacks. Personnel — Personnel expenses consist of compensation to the Company's personnel, including salaries, stock-based compensation, bonuses,payroll taxes and employee health benefits. Included in "Accrued expenses and other current liabilities" in the Consolidated Balance Sheets are accruedcompensation liabilities of $242.6 million and $186.1 million at December 31, 2016 and 2015, respectively. Stock-Based Compensation — Stock-based compensation is recognized in the financial statements based upon fair value. The fair value ofperformance share units and restricted stock units is determined based on the number of units granted and the quoted price of the Company's common stockas of the grant date or acquisition date. Stock-based compensation related to performance share units reflects the estimated probable outcome at the end ofthe performance period. The fair value of employee stock options assumed in acquisitions was determined using the Black Scholes model and the marketvalue of the Company's common stock at the respective acquisition dates. Fair value is recognized as expense on a straight line basis, net of estimatedforfeitures, over the employee requisite service period (see "Recent Accounting Pronouncements" described later in this footnote for accounting changes thatare effective January 1, 2017). The benefits of tax deductions in excess of recognized compensation costs are reported as a credit to additional paid-in capital and as financing cashflows, but only when such excess tax benefits are realized by a reduction to current taxes payable. See Note 3 for further information on stock-based awards. Information Technology — Information technology expenses consist primarily of: (1) software license and system maintenance fees; (2) datacommunications and other expenses associated with operating our services; (3) outsourced data center costs; and (4) payments to outside consultants. Income Taxes — The Company accounts for income taxes under the asset and liability method. The Company records the estimated future taxeffects of temporary differences between the tax bases of assets and liabilities and amounts reported in the Consolidated Balance Sheets, as well as operatingloss and tax credit carryforwards. Deferred taxes are classified as noncurrent on the balance sheet. The Company records deferred tax assets to the extent it believes these assets will more likely than not be realized. The Company regularly reviewsits deferred tax assets for recoverability considering historical profitability, projected future taxable income, the expected timing of the reversals of existingtemporary differences, the carryforward periods available for tax reporting purposes, and tax planning strategies. A valuation allowance is provided when itis more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on thegeneration of future taxable income during the period in which related temporary differences become deductible. In determining the future tax consequencesof events that have been recognized in the financial statements or tax returns, significant judgments, estimates, and interpretation of statutes are required.Deferred taxes are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences areexpected to be recovered or settled. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactmentdate of such change. Income taxes are not accrued for unremitted earnings of international subsidiaries that have been or are intended to be indefinitely reinvestedoutside of the United States. The Company recognizes liabilities when it believes that uncertain positions may not be fully sustained upon review by the tax authorities. Liabilities recognized for uncertain tax positions are based on a two step approach for recognition and measurement. First, the Company evaluates the taxposition for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on auditbased on its technical merits. Secondly, the Company measures the tax benefit as the largest amount that is more than 50% likely of being realized uponultimate settlement. Interest and penalties attributable to uncertain tax positions, if any, are recognized as a component of income tax expense. See Note 13for further details on income taxes. 79 Segment Reporting — The Company determined that its brands constitute its operating segments. The Company's Booking.com brand represents asubstantial majority of gross profit and net income. Based on similar economic characteristics and other similar operating factors, the Company hasaggregated the operating segments into one reportable segment. For geographic information, see Note 16. Foreign Currency Translation — The functional currency of the Company's foreign subsidiaries is generally their respective local currency. Assetsand liabilities are translated into U.S. Dollars at the rate of exchange existing at the balance sheet date. Income statement amounts are translated at averagemonthly exchange rates applicable for the period. Translation gains and losses are included as a component of "Accumulated other comprehensive income(loss)" in the Company's Consolidated Balance Sheets. Foreign currency transaction gains and losses are included in "Foreign currency transactions andother" in the Company's Consolidated Statements of Operations.In November 2015, the Company issued Senior Notes due November 25, 2022 for an aggregate principal amount of 750 million Euros. In March2015, the Company issued Senior Notes due March 3, 2027 for an aggregate principal amount of 1.0 billion Euros. In September 2014, the Company issuedSenior Notes due September 23, 2024 for an aggregate principal amount of 1.0 billion Euros. The Company designated the carrying value, plus accruedinterest, of these Euro-denominated Senior Notes as a hedge of the Company's net investment in Euro functional currency subsidiaries. The foreign currencytransaction gains or losses on these liabilities and the foreign currency translation gains or losses from translating the Euro-denominated net assets of thesesubsidiaries into U.S. Dollars are included as a component of "Accumulated other comprehensive income (loss)" in the Company's Consolidated BalanceSheets (see Notes 10 and 12).Derivative Financial Instruments — As a result of the Company's international operations, it is exposed to various market risks that may affect itsconsolidated results of operations, cash flow and financial position. These market risks include, but are not limited to, fluctuations in currency exchangerates. The Company's primary foreign currency exposures are in Euros and British Pound Sterling, in which it conducts a significant portion of its businessactivities. As a result, the Company faces exposure to adverse movements in currency exchange rates as the financial results of its international operationsare translated from local currencies into U.S. Dollars upon consolidation. Additionally, foreign exchange rate fluctuations on transactions denominated incurrencies other than the functional currency result in gains and losses that are reflected in income. The Company may enter into derivative instruments to hedge certain net exposures of nonfunctional currency denominated assets and liabilities andthe volatility associated with translating earnings for its international businesses into U.S. Dollars, even though it does not elect to apply hedge accountingor hedge accounting does not apply. Gains and losses resulting from a change in fair value for these derivatives are reflected in income in the period in whichthe change occurs and are recognized in the Consolidated Statements of Operations in "Foreign currency transactions and other." Cash flows related to thesecontracts are classified within "Net cash provided by operating activities" on the cash flow statement. The Company, from time to time, utilizes derivative instruments to hedge the impact of changes in currency exchange rates on the net assets of itsforeign subsidiaries. These instruments are designated as net investment hedges. Hedge ineffectiveness is assessed and measured based on changes in forwardexchange rates. The Company records gains and losses on these derivative instruments as currency translation adjustments, which offset a portion of thetranslation adjustments related to the foreign subsidiaries' net assets. Gains and losses are recognized in the Consolidated Balance Sheet in "Accumulatedother comprehensive income (loss)" and will be realized upon a partial sale or liquidation of the investment. The Company formally documents allderivatives designated as hedging instruments for accounting purposes, both at hedge inception and on an on-going basis. These net investment hedgesexpose the Company to liquidity risk as the derivatives have an immediate cash flow impact upon maturity, which is not offset by the translation of theunderlying hedged equity. The cash flows from these contracts are classified within "Net cash used in investing activities" on the cash flow statement. The Company does not use derivative instruments for trading or speculative purposes. The Company recognizes all derivative instruments on thebalance sheet at fair value and its derivative instruments are generally short-term in duration. The derivative instruments do not contain leverage features. The Company is exposed to the risk that counterparties to derivative instruments may fail to meet their contractual obligations. The Companyregularly reviews its credit exposure as well as assessing the creditworthiness of its counterparties. See Note 5 for further detail on derivatives. 80 Recent Accounting PronouncementsSimplifying the Test for Goodwill ImpairmentIn January 2017, the Financial Accounting Standards Board ("FASB") issued a new accounting update to simplify the test for goodwill impairmentby eliminating Step 2, which measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill, which requires ahypothetical purchase price allocation, with the carrying amount of that reporting unit’s goodwill. Under this update, an entity would perform its quantitativeannual, or interim, goodwill impairment test using the current Step 1 test and recognize an impairment charge for the excess of the carrying value of areporting unit over its fair value.For public business entities, this update is effective for their annual or any interim goodwill impairment tests in fiscal years beginning afterDecember 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests occurring after January 1, 2017. The accounting update willbe applied prospectively. The Company is currently evaluating when it will adopt this update and what the impact upon adoption will be, if any.Definition of a BusinessIn January 2017, the FASB issued a new accounting update to clarify the definition of a business and provide additional guidance to assist entitieswith evaluating whether transactions should be accounted for as asset acquisitions (or disposals) or business combinations (or disposals of a business). Underthis update, an entity first determines whether substantially all of the fair value of the assets acquired is concentrated in a single identifiable asset or a groupof similar identifiable assets. If this criterion is met, the transaction should be accounted for as an asset acquisition as opposed to a business combination.This distinction is important because the accounting for an asset acquisition significantly differs from the accounting for a business combination. This updateeliminates the requirement to evaluate whether a market participant could replace missing elements (e.g. inputs or processes), narrows the definition ofoutputs and requires that a business include, at a minimum, an input and a substantive process that together significantly contribute to the ability to createoutputs. For public business entities, this update is effective for annual reporting periods beginning after December 15, 2017, including interim periodswithin those annual reporting periods. The accounting update will be applied prospectively and early adoption is permitted. The Company expects to earlyadopt this update in the first quarter of 2017 and does not expect a significant impact to its Consolidated Financial Statements.Restricted CashIn November 2016, the FASB issued a new accounting update on the classification and presentation of restricted cash in the statement of cash flowsto address the diversity in practice. This accounting update requires entities to show changes in cash, cash equivalents and restricted cash on a combinedbasis in the statement of cash flows. In addition, this accounting guidance requires a reconciliation of the total cash, cash equivalent and restricted cash in thestatement of cash flows to the related captions in the balance sheet if cash, cash equivalents and restricted cash are presented in more than one line item in thebalance sheet.This accounting update is effective for public business entities for fiscal years beginning after December 15, 2018, including those interim periodswithin those fiscal years. The Company early adopted this accounting update in the fourth quarter of 2016 and applied it retrospectively to all prior periodspresented, therefore, the Consolidated Statements of Cash Flows for the years ended December 31, 2015 and 2014 were adjusted. See the section above onaccounting policies related to "Restricted Cash" for the reconciliation of cash, cash equivalent and restricted cash reported in the Consolidated BalanceSheets to the total shown in the Consolidated Statements of Cash Flows.Intra-entity Transfers of Assets Other Than InventoryIn October 2016, the FASB issued new accounting guidance on income tax accounting associated with intra-entity transfers of assets other thaninventory. This accounting update, which is part of the FASB's simplification initiative, is intended to reduce diversity in practice and the complexity of taxaccounting, particularly for those transfers involving intellectual property. This new guidance requires an entity to recognize the income tax consequences ofan intra-entity transfer of an asset other than inventory when the transfer occurs.For public business entities, this update is effective for annual reporting periods beginning after December 15, 2017. Entities are required to applythis accounting update on a modified retrospective basis with a cumulative-effect adjustment to81 retained earnings as of the beginning of the period of adoption. The Company expects to early adopt this update in the first quarter of 2017 and the adoptionof this accounting update will have an insignificant impact to the Company's Consolidated Financial Statements.Measurement of Credit Losses on Financial InstrumentsIn June 2016, the FASB issued new accounting guidance on the measurement of credit losses for financial assets measured at amortized cost, whichincludes 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 becollected, (2) recognize this allowance and changes in the allowance during subsequent periods through net income and (3) consider relevant informationabout past events, current conditions and reasonable and supportable forecasts in assessing the lifetime expected credit losses. For available-for-sale debtsecurities, this new guidance made several targeted amendments to the existing other-than-temporary impairment model, including (1) requiring disclosure ofthe 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-notrequired 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 update is effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscalyears. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Entities are requiredto apply this accounting update on a modified retrospective basis with a cumulative-effect adjustment to retained earnings as of the beginning of the periodof adoption. The Company is currently evaluating the impact to its Consolidated Financial Statements of adopting this new guidance.Share-based CompensationIn March 2016, the FASB issued new accounting guidance to improve the accounting for certain aspects of share-based payment transactions as partof its simplification initiative. The key provisions of this accounting update are: (1) recognizing current excess tax benefits in the income statement in theperiod the benefits are deducted on the income tax return as opposed to an adjustment to additional paid-in capital in the period the benefits are realized byreducing a current income tax liability; (2) allowing an entity-wide election to account for forfeitures related to service conditions as they occur instead ofestimating the total number of awards that will be forfeited because the requisite service period will not be rendered; (3) allowing the net settlement of anequity award for employee statutory tax withholding purposes to not exceed the maximum statutory tax rate by relevant tax jurisdiction instead ofwithholding taxes for each employee based on a minimum statutory withholding tax rate; and (4) requiring the presentation of excess tax benefits asoperating cash flow and cash payments for employee statutory tax withholding related to vested stock awards as financing cash flow in the ConsolidatedStatements of Cash Flows. Under this new accounting standard, all previously unrecognized equity deductions will be recognized as a deferred tax asset, netof any valuation allowance, with a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption of this standard.For public business entities, this update is effective for annual reporting periods beginning after December 15, 2016, including interim periodswithin those annual reporting periods. Early adoption was permitted. The Company will adopt this accounting update in the first quarter of 2017. TheCompany will record a deferred tax asset of approximately $300 million related to previously unrecognized U.S. equity deductions, with an offsettingcumulative-effect adjustment to retained earnings as of January 1, 2017. The Company will elect to account for forfeitures related to service conditions asthey occur, as a result, there will be a cumulative net charge to retained earnings for $7.0 million (forfeiture true-up adjustment less deferred tax benefit) andrecognition of deferred tax assets for $2.0 million, with an offsetting credit to additional paid-in capital for $9.0 million. In addition, the Company will electto change the presentation of excess tax benefits in the consolidated statements of cash flows for periods prior to January 1, 2017 to reflect these excess taxbenefits in operating cash flows instead of financing cash flows.LeasesIn February 2016, the FASB issued a new accounting standard intended to improve the financial reporting of lease transactions. The newaccounting standard requires lessees to recognize an asset and a liability on the balance sheet for the right and obligation created by entering into a leasetransaction for all leases with the exception of short-term leases. The new standard retains the dual-model concept by requiring entities to determine if a leaseis an operating or financing lease and the82 current "bright line" percentages could be used as guidance in applying the new standard. The lessor accounting model remains largely unchanged. The newstandard significantly expands qualitative and quantitative disclosures for lessees.The update is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is allowed. Entities are required to recognize and measure leases at the beginning of the earliest period presented using a modifiedretrospective approach. The Company is currently evaluating the impact to its Consolidated Financial Statements of adopting this new guidance.Recognition and Measurement of Financial InstrumentsIn January 2016, the FASB issued a new accounting update which amends the guidance on the recognition and measurement of financialinstruments. The update requires (1) an entity to measure equity investments (except those accounted for under the equity method or those that result inconsolidation of the investee) at fair value with changes in fair value recognized in net income rather than accumulated other comprehensive income (loss);(2) allows an entity to elect to measure those equity investments that do not have a readily determinable fair value at cost less impairment, if any, plus orminus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer; (3) simplifies theimpairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; and (4)clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination withthe entity’s evaluation of their other deferred tax assets.This update is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption,although allowed in certain circumstances, is not applicable to the Company. An entity would apply this update by a cumulative-effect adjustment to thebalance sheet as of the beginning of the fiscal year of adoption. After the adoption of this new accounting guidance, in the first quarter of 2018, the Companywill record fair value changes in its investments in Ctrip equity securities in net income, which could vary significantly quarter to quarter (see Note 4 for theircarrying values and fair values of these equity investments). In addition, the Company intends to continue to use the cost method of accounting for equityinvestments without a readily determinable fair value.Revenue from Contracts with CustomersIn May 2014, the FASB issued a new accounting standard on the recognition of revenue from contracts with customers that was designed to creategreater comparability for financial statement users across industries and jurisdictions. The core principle of this standard is that an "entity recognizes revenueto depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled inexchange for those goods or services." The new standard also requires enhanced disclosures on the nature, amount, timing and uncertainty of revenue fromcontracts with customers. Since May 2014, the FASB has issued several amendments to this standard, including additional guidance, and deferred theeffective date for public business entities to annual and interim periods beginning after December 15, 2017.The Company will adopt this new standard in the first quarter of 2018 by applying the modified retrospective transition approach, which means thatrevenues for 2016 and 2017 will be reported on a historical basis and revenues for 2018 will be reported on the new basis and historical basis. Based on theCompany's preliminary analysis, the revenue standard is expected to change the timing of revenue recognition for travel reservation services, but theCompany does not currently expect material impacts to its annual gross profit or net income, although the effects on quarterly gross profit and net incomemay be more significant. In addition, the adoption of the revenue standard is expected to change the presentation of Name Your Own Price® revenue from"gross" to "net" reporting, which will decrease revenue and cost of revenue equally, but have no impact on gross profit or net income.3.

As a result, the Company analyzed all informationavailable and based on the best estimate of the fair value of this investment, recognized an impairment of approximately $50 million for the three monthsended March 31, 2016. In the second quarter of 2016, after discussions with Hotel Urbano's management, the Company reviewed their additional fundingneeds and based on its business prospects, the Company recognized an impairment of approximately $10 million for the three months ended June 30, 2016 towrite-off the remainder of its investment in Hotel Urbano.

The definition of each input is described below:Level 1:Quoted prices in active markets that are accessible by the Company at the measurement date for identical assets and liabilities.Level 2:Inputs that are observable, either directly or indirectly. Such prices may be based upon quoted prices for identical or comparablesecurities in active markets or inputs not quoted on active markets, but corroborated by market data.Level 3:Unobservable inputs are used when little or no market data is available. Investments in corporate debt securities, U.S. and international government securities, commercial paper, government agency securities, convertibledebt securities and municipal securities are considered "Level 2" valuations because the Company has access to quoted prices, but does not have visibility tothe volume and frequency of trading for all of these investments. For the Company's investments, a market approach is used for recurring fair valuemeasurements and the valuation techniques use inputs that are observable, or can be corroborated by observable data, in an active marketplace. The Company's derivative instruments are valued using pricing models. Pricing models take into account the contract terms as well as multipleinputs where applicable, such as interest rate yield curves, option volatility and currency rates. Derivatives are considered "Level 2" fair value measurements.The Company's derivative instruments are typically short-term in nature.90 As of December 31, 2016 and 2015, the Company's cash consisted of bank deposits. Other financial assets and liabilities, including restricted cash,accounts receivable, accounts payable, accrued expenses and deferred merchant bookings are carried at cost which approximates their fair value because ofthe short-term nature of these items. As of December 31, 2016 and 2015, the Company held investments in equity securities of private companies ofapproximately $7.6 million and $62.3 million, respectively, and these investments are accounted for under the cost method of accounting (see Note 4). SeeNote 4 for information on the carrying value of available-for-sale investments, Note 10 for the estimated fair value of the Company's outstanding SeniorNotes and Note 18 for the Company's contingent liabilities associated with business acquisitions.In the normal course of business, the Company is exposed to the impact of foreign currency fluctuations. The Company limits these risks byfollowing established risk management policies and procedures, including the use of derivatives. See Note 2 for the Company's accounting policy onderivative financial instruments. Derivatives Not Designated as Hedging Instruments — The Company is exposed to adverse movements in currency exchange rates as the operatingresults of its international operations are translated from local currency into U.S. Dollars upon consolidation. The Company enters into average-ratederivative contracts to hedge translation risk from short-term foreign exchange rate fluctuations for the Euro, British Pound Sterling and certain othercurrencies versus the U.S. Dollar. As of December 31, 2016 and 2015, there were no outstanding derivative contracts related to foreign currency translationrisk. Foreign exchange gains of $3.4 million for the year ended December 31, 2016, foreign exchange losses of $6.6 million for the year ended December 31,2015 and foreign exchange gains of $13.7 million for the year ended December 31, 2014, were recorded related to these derivatives in "Foreign currencytransactions and other" in the Consolidated Statements of Operations.The Company also enters into foreign currency forward contracts to hedge its exposure to the impact of movements in currency exchange rates on itstransactional balances denominated in currencies other than the functional currency. Currency exchange derivatives outstanding as of December 31, 2016associated with foreign currency transaction risks resulted in a net liability of $0.3 million, with a liability in the amount of $1.0 million recorded in"Accrued expenses and other current liabilities" and an asset in the amount of $0.7 million recorded in "Prepaid expenses and other current assets" in theConsolidated Balance Sheet.

Derivatives associated withthese transaction risks resulted in foreign exchange losses of $15.8 million, $15.3 million and $21.8 million for the years ended December 31, 2016, 2015and 2014, respectively. These mark-to-market adjustments on the derivative contracts, offset by the effect of changes in currency exchange rates ontransactions denominated in currencies other than the functional currency, resulted in net losses of $13.9 million, $13.8 million and $11.8 million for theyears ended December 31, 2016, 2015 and 2014, respectively. These net impacts are reported in “Foreign currency transactions and other” in theConsolidated Statements of Operations.

Diluted net income per share is based upon the weighted-average number of common and common equivalentshares outstanding during the period. Common equivalent shares related to stock options, restricted stock units, and performance share units are calculated using the treasury stockmethod. Performance share units are included in the weighted-average common equivalent shares based on the number of shares that would be issued if theend of the reporting period were the end of the performance period, if the result would be dilutive. The Company's convertible notes have net share settlement features requiring the Company upon conversion to settle the principal amount of thedebt for cash and the conversion premium for cash or shares of the Company's common stock, at the Company's option. The convertible notes are included inthe calculation of diluted net income per share if their inclusion is dilutive under the treasury stock method.A reconciliation of the weighted-average number of shares outstanding used in calculating diluted earnings per share is as follows (in thousands): For the Year Ended December 31,2016 2015 2014Weighted-average number of basic common shares outstanding49,491 50,940 52,301Weighted-average dilutive stock options, restricted stock units and performanceshare units238 395 340Assumed conversion of Convertible Senior Notes334 258 382Weighted-average number of diluted common and common equivalent sharesoutstanding50,063 51,593 53,023Anti-dilutive potential common shares2,443 2,563 2,574 Anti-dilutive potential common shares for the years ended December 31, 2016, 2015 and 2014 include approximately 2.0 million shares, 2.1million shares and 2.1 million shares, respectively, that could be issued under the Company's outstanding convertible notes. Under the treasury stockmethod, the convertible notes will generally have an anti-dilutive impact on net income per share if the conversion prices for the convertible notes exceedthe Company's average stock price.92 8.PROPERTY AND EQUIPMENT Property and equipment at December 31, 2016 and 2015 consisted of the following (in thousands): 2016 2015 EstimatedUseful Lives(years)Computer equipment and software$522,675 $396,961 2 to 5 yearsLeasehold improvements143,191 109,724 2 to 11 yearsOffice equipment, furniture and fixtures34,176 28,447 2 to 10 yearsBuilding construction-in-progress5,945 — Total705,987 535,132 Less: accumulated depreciation(358,970) (260,346) Property and equipment, net$347,017 $274,786 Fixed asset depreciation expense was approximately $140.1 million, $101.5 million and $78.2 million for the years ended December 31, 2016, 2015and 2014, respectively.9.INTANGIBLE ASSETS AND GOODWILL The Company's intangible assets at December 31, 2016 and 2015 consisted of the following (in thousands): December 31, 2016 December 31, 2015 Gross CarryingAmount AccumulatedAmortization Net CarryingAmount Gross CarryingAmount AccumulatedAmortization Net CarryingAmount AmortizationPeriod WeightedAverage UsefulLife Supply and distributionagreements$809,287 $(270,813) $538,474 $824,932 $(227,994) $596,938 10 - 20 years 16 years Technology112,141 (80,549) 31,592 112,639 (61,404) 51,235 1 - 5 years 5 years Patents1,623 (1,598) 25 1,623 (1,562) 61 15 years 15 years Internet domain names39,495 (25,089) 14,406 40,352 (20,954) 19,398 2 - 20 years 8 years Trade names1,667,221 (261,412) 1,405,809 1,671,356 (183,101) 1,488,255 4-20 years 20 years Non-competeagreements21,900 (18,321) 3,579 22,847 (11,201) 11,646 3-4 years 3 years Other— — — 135 (135) — Total intangible assets$2,651,667 $(657,782) $1,993,885 $2,673,884 $(506,351) $2,167,533 Intangible assets are amortized on a straight-line basis.

See Note 18for further information on the acquisition of OpenTable.As of September 30, 2016, the Company performed its annual goodwill impairment testing. Other than OpenTable, the fair values of the Company’sreporting units substantially exceeded their respective carrying values. For OpenTable, the Company recognized a non-cash impairment charge to goodwillof $940.7 million, which is not tax deductible, resulting in an adjusted carrying value of OpenTable goodwill of $580.1 million as of September 30, 2016.The goodwill impairment charge was included in operating expenses in the Consolidated Statement of Operations for the year ended December 31, 2016.OpenTable’s estimated fair value was determined using a combination of standard valuation techniques, including an income approach (discounted cashflows) and market approaches (EBITDA multiples of comparable publicly-traded companies and precedent transactions). Also, the Company tested therecoverability of OpenTable’s other long-lived assets and concluded there was no impairment as of September 30, 2016. Since the annual impairment test,there have been no further events or changes in circumstances to indicate a potential impairment.The goodwill impairment was primarily the result of a change in OpenTable’s business strategy that occurred during the third quarter 2016.OpenTable’s post-acquisition strategy was premised on significant and rapid investment in international expansion and various other growth initiatives,resulting in near-term reduced earnings and profit margins but with the goal of achieving significantly increased revenues and profitability in the long term.This strategy had resulted in limited progress as of September 30, 2016. As a result, while OpenTable intends to continue to pursue and invest in internationalexpansion and its other growth initiatives, it intends to do so in a more measured and deliberate manner. This change in strategy resulted in OpenTableupdating its forecasted financial results to reflect (a) a material reduction in forecasted long-term financial results from these initiatives, partially offset by (b)improved earnings and profit margins in the near term as a result of the reduced investments. Based on the updated forecast, the Company estimated asignificant reduction in the fair value of the OpenTable business and recorded the goodwill impairment discussed above.10. DEBT Revolving Credit FacilityIn June 2015, the Company entered into a $2.0 billion five-year unsecured revolving credit facility with a group of lenders. Borrowings under therevolving credit facility will bear interest, at the Company’s option, at a rate per annum equal to either (i) the adjusted LIBOR for the interest period in effectfor such borrowing plus an applicable margin ranging from 0.875% to 1.50%; or (ii) the greatest of (a) Bank of America, N.A.'s prime lending rate, (b) thefederal funds rate plus 0.5%, and (c) an adjusted LIBOR for an interest period of one month plus 1.00%, plus an applicable margin ranging from 0.00% to94 0.50%. Undrawn balances available under the revolving credit facility are subject to commitment fees at the applicable rate ranging from 0.085% to 0.20%.The revolving credit facility provides for the issuance of up to $70.0 million of letters of credit as well as borrowings of up to $50.0 million on same-day notice, referred to as swingline loans. Borrowings under the revolving credit facility may be made in U.S. Dollars, Euros, British Pounds Sterling and anyother foreign currency agreed to by the lenders. The proceeds of loans made under the facility would be used for working capital and general corporatepurposes, which could include acquisitions, share repurchases or debt repayments. The Company paid $4.0 million in debt issuance costs related to therevolving credit facility during the year ended December 31, 2015. As of December 31, 2016 and 2015, there were no borrowings outstanding andapproximately $3.8 million and $2.5 million of letters of credit issued under this facility.Upon entering into this new revolving credit facility, the Company terminated its $1.0 billion five-year revolving credit facility entered into inOctober 2011 and recognized interest expense of $1.0 million related to the write-off of the remaining unamortized debt issuance costs in 2015.Outstanding Debt Outstanding debt as of December 31, 2016 consisted of the following (in thousands): December 31, 2016 OutstandingPrincipalAmount Unamortized DebtDiscount and Debt Issuance Cost CarryingValueShort-term debt: 1.0% Convertible Senior Notes due March 2018 $1,000,000 $(32,266) $967,734Long-term debt: 0.35% Convertible Senior Notes due June 2020 $1,000,000 $(90,251) $909,7490.9% Convertible Senior Notes due September 2021 1,000,000 (104,592) 895,4082.15% (€750 Million) Senior Notes due November 2022 791,063 (5,336) 785,7272.375% (€1 Billion) Senior Notes due September 2024 1,054,750 (12,861) 1,041,8893.65% Senior Notes due March 2025 500,000 (3,727) 496,2733.6% Senior Notes due June 2026 1,000,000 (7,619) 992,3811.8% (€1 Billion) Senior Notes due March 2027 1,054,750 (5,655) 1,049,095Total long-term debt $6,400,563 $(230,041) $6,170,522 Outstanding debt as of December 31, 2015 consisted of the following (in thousands): December 31, 2015 OutstandingPrincipalAmount Unamortized DebtDiscount and Debt Issuance Cost CarryingValueLong-term debt: 1.0% Convertible Senior Notes due March 2018 $1,000,000 $(58,929) $941,0710.35% Convertible Senior Notes due June 2020 1,000,000 (114,898) 885,1020.9% Convertible Senior Notes due September 2021 1,000,000 (125,258) 874,7422.15% (€750 Million) Senior Notes due November 2022 815,217 (6,555) 808,6622.375% (€1 Billion) Senior Notes due September 2024 1,086,957 (14,688) 1,072,2693.65% Senior Notes due March 2025 500,000 (4,160) 495,8401.8% (€1 Billion) Senior Notes due March 2027 1,086,957 (6,200) 1,080,757Total long-term debt $6,489,131 $(330,688) $6,158,443 Based upon the closing price of the Company's common stock for the prescribed measurement periods during the three months ended December 31,2016, the contingent conversion threshold on the 2018 Notes (as defined below) was exceeded. Therefore, the 2018 Notes are currently convertible at theoption of the holders, and, accordingly, the Company reported the carrying value of the 2018 Notes as a current liability in the Company's ConsolidatedBalance Sheet as of December 31, 2016.95 Since these notes are convertible at the option of the holders and the principal amount is required to be paid in cash, the Company reclassified theunamortized debt discount for the 2018 Notes in the amount of $28.5 million before tax as of December 31, 2016 from additional paid-in-capital toconvertible debt in the mezzanine section in the Company's Consolidated Balance Sheet. The contingent conversion threshold on the 2018 Notes was notexceeded at December 31, 2015, therefore, the 2018 Notes were reported as a non-current liability in the Consolidated Balance Sheet. The determination ofwhether or not the 2018 Notes are convertible is performed on a quarterly basis. Consequently, the 2018 Notes may not be convertible in future quarters.The contingent conversion thresholds on the 2020 Notes (as defined below) and the 2021 Notes (as defined below) were not exceeded atDecember 31, 2016 and December 31, 2015, and therefore these notes were reported as a non-current liability in the Consolidated Balance Sheets.Fair Value of DebtAs of December 31, 2016 and 2015, the estimated fair value of the outstanding Senior Notes was approximately $8.4 billion and $7.0 billion,respectively, and was considered a "Level 2" fair value measurement (see Note 5). Fair value was estimated based upon actual trades at the end of thereporting period or the most recent trade available as well as the Company's stock price at the end of the reporting period. A substantial portion of the marketvalue of the Company's debt in excess of the outstanding principal amount relates to the conversion premium on the Convertible Senior Notes.Convertible DebtIf the note holders exercise their option to convert, the Company delivers cash to repay the principal amount of the notes and delivers shares ofcommon stock or cash, at its option, to satisfy the conversion value in excess of the principal amount. In cases where holders decide to convert prior to thematurity date, the Company charges the proportionate amount of remaining debt issuance costs to interest expense.

The value assigned to the debt component is the estimated fair value, as of the issuance date, of a similar bond without theconversion feature. The difference between the bond cash proceeds and this estimated fair value, representing the value assigned to the equity component, isrecorded as a debt discount. Debt discount is amortized using the effective interest rate method over the period from the origination date through the statedmaturity date. The Company estimated the straight debt borrowing rates at debt origination to be 3.50% for the 2018 Notes, 3.13% for the 2020 Notes and3.18% for the 2021 Notes. The yield to maturity was estimated at an at-market coupon priced at par.

Debt discount after tax of $69.1 million ($115.2 million before tax) less financing costs associated with the equity component of convertible debt of$1.6 million after tax was recorded in additional paid-in capital related to the 2015 Notes at March 31, 2010.For the years ended December 31, 2016, 2015 and 2014, the Company recognized interest expense of $94.5 million, $92.7 million and $75.3million, respectively, related to convertible notes, comprised of $22.5 million, $22.6 million and $17.1 million, respectively, for the contractual couponinterest, $67.5 million, $65.6 million and $54.4 million, respectively, related to the amortization of debt discount and $4.5 million, $4.5 million and $3.8million, respectively, related to the amortization of debt issuance costs. For the years ended December 31, 2016, 2015 and 2014, included in theamortization of debt discount mentioned above was $2.8 million, $2.7 million and $2.6 million, respectively, of original issuance discount amortizationrelated to the 2020 Notes. In addition, the Company incurred interest expense for the write-off of unamortized debt issuance costs related to debt conversionsof $0.5 million for the year ended December 31, 2014. The remaining period for amortization97 of debt discount and debt issuance costs is the period until the stated maturity date for the respective debt. The weighted-average effective interest rates forthe years ended December 31, 2016, 2015, and 2014 are 3.4%, 3.4% and 3.5%, respectively. In addition, if the Company's convertible debt is redeemed or converted prior to maturity, a gain or loss on extinguishment is recognized. The gainor loss is the difference between the fair value of the debt component immediately prior to extinguishment and its carrying value. To estimate the fair valueof the debt at the conversion date, the Company estimated its straight debt borrowing rate, considering its credit rating and straight debt of comparablecorporate issuers. For the year ended December 31, 2014 the Company recognized non-cash losses of $6.3 million ($3.8 million after tax) in "Foreigncurrency transactions and other" in the Consolidated Statement of Operations in connection with the conversion of the 2015 Notes.Other Long-term DebtIn May 2016, the Company issued Senior Notes due June 1, 2026, with an interest rate of 3.6% (the "2026 Notes") for an aggregate principalamount of $1.0 billion.

The foreign currency transaction gains or losses on these liabilities are measuredbased upon changes in spot rates and are recorded in "Accumulated other comprehensive income (loss)" in the Consolidated Balance Sheets. The Euro-denominated net assets of these subsidiaries are translated into U.S. Dollars at each balance sheet date, with effects of foreign currency changes also reportedin "Accumulated other comprehensive income (loss)" in the Consolidated Balance Sheets. Since the notional amount of the recorded Euro-denominated debtand related interest are not greater than the notional amount of the Company's net investment, the Company does not expect to incur any ineffectiveness onthis hedge.Debt discount is amortized using the effective interest rate method over the period from the origination date through the stated maturity date. TheCompany estimated the effective interest rates at debt origination to be 3.62% for the 2026 Notes, 2.20% for the 2022 Notes, 3.68% for the 2025 Notes,1.80% for the 2027 Notes and 2.48% for the 2024 Notes.For the years ended December 31, 2016 and 2015, the Company recognized interest expense of $108.0 million and $61.5 million, respectively,related to other long-term debt which was comprised of $104.1 million and $59.0 million, respectively, for the contractual coupon interest, $1.5 million and$1.1 million, respectively, related to the amortization of debt discount and $2.4 million and $1.4 million, respectively, related to the amortization of debtissuance costs. The remaining98 period for amortization of debt discount and debt issuance costs is the period until the stated maturity dates for the respective debt.In March 2016, the Company received a ten-year loan from the State of Connecticut in the amount of $2.5 million with an interest rate of 1% inconnection with the construction of office space in Connecticut. As of December 31, 2016, the loan is reported in "Other long-term liabilities" in theConsolidated Balance Sheet. The loan will be forgiven if certain employment and salary conditions are met in 2017 for a portion of the loan and in 2019 forthe remaining balance of the loan.11.TREASURY STOCK In the first quarter of 2016, the Company's Board of Directors authorized a program to repurchase up to $3.0 billion of the Company's common stock,in addition to amounts previously authorized. In the year ended December 31, 2016, the Company repurchased 635,877 shares of its common stock in theopen market for an aggregate cost of $861.5 million, which included stock repurchases in December 2016 of 10,215 shares for an aggregate cost of $15.0million that were settled in January 2017. As a result, the Consolidated Balance Sheet at December 31, 2016 includes $15.0 million in "Accrued expensesand other current liabilities" for these unsettled stock repurchases. The Consolidated Statement of Cash Flows for the year ended December 31, 2016 excludesthe impact of these stock repurchases settled in January 2017. As of December 31, 2016, the Company had a remaining authorization of $2.1 billion to purchase its common stock. In the first quarter of 2017, theCompany's Board of Directors authorized a program to repurchase up to $2.0 billion of the Company's common stock, in addition to amounts previouslyauthorized. The Company may make additional repurchases of shares under its stock repurchase program, depending on prevailing market conditions,alternate uses of capital and other factors. Whether and when to initiate and/or complete any purchase of common stock and the amount of common stockpurchased will be determined at the Company's discretion.In the first quarter of 2015, the Company's Board of Directors authorized the repurchase of up to $3.0 billion of the Company's common stock, inaddition to amounts previously authorized. In the year ended December 31, 2015, the Company repurchased 2,468,259 shares of its common stock in theopen market for an aggregate cost of $3.0 billion related to this authorization and 5,813 shares for an aggregate cost of $7.2 million covered under theremaining authorization as of December 31, 2014 to repurchase common stock.In 2014, the Company repurchased 114,645 share of its common stock in privately negotiated, off-market transactions and 438,897 shares of itscommon stock in the open market for aggregate costs of $147.3 million and $500.0 million, respectively. All these shares were covered under the Company'sremaining authorizations as of December 31, 2013 to repurchase common stock.The Board of Directors has given the Company the general authorization to repurchase shares of its common stock to satisfy employee withholdingtax obligations related to stock-based compensation. In the years ended December 31, 2016, 2015 and 2014, the Company repurchased 127,107, 65,849, and77,761 shares at an aggregate cost of $167.0 million, $81.9 million and $103.1 million, respectively, to satisfy employee withholding taxes related to stock-based compensation. As of December 31, 2016, there were 13,190,929 shares of the Company's common stock held in treasury.99 12.ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) The table below provides the balances for each classification of accumulated other comprehensive income (loss) as of December 31, 2016 and 2015(in thousands): December 31,2016 December 31,2015Foreign currency translation adjustments, net of tax (1)$(311,247) $(217,263)Net unrealized gain on marketable securities, net of tax (2)176,563 462,115Accumulated other comprehensive income (loss)$(134,684) $244,852(1) Foreign currency translation adjustments, net of tax, include net losses from fair value adjustments of $35.0 million after tax ($52.6 million beforetax) and $34.8 million after tax ($52.6 million before tax) at December 31, 2016 and 2015, respectively, associated with settled derivatives thatpreviously had been designated as net investment hedges (see Note 5).Foreign currency translation adjustments, net of tax, include foreign currency transaction gains of $182.6 million after tax ($310.4 million beforetax) and $126.8 million after tax ($220.5 million before tax) at December 31, 2016 and 2015, respectively, associated with the Company's 2022Notes, 2024 Notes and 2027 Notes. The 2022 Notes, 2024 Notes and 2027 Notes are Euro-denominated debt and are designated as hedges of certainof the Company's Euro-denominated net assets (see Note 10).The remaining balance in foreign currency translation adjustments excludes income taxes as a result of the Company's intention to indefinitelyreinvest the earnings of its international subsidiaries outside of the United States.(2) The unrealized gains before tax at December 31, 2016 and 2015 were $185.9 million and $456.1 million, respectively, of which unrealized gains of$148.5 million and $481.3 million, respectively, were exempt from tax in the Netherlands and unrealized gains of $37.4 million and unrealizedlosses of $25.2 million, respectively, were taxable.13.INCOME TAXES International pre-tax income was $3.7 billion, $3.1 billion and $2.9 billion for the years ended December 31, 2016, 2015 and 2014, respectively.U.S. pre-tax loss was $983.1 million for the year ended December 31, 2016 and U.S. pre-tax income was $35.4 million and $98.4 million for the years endedDecember 31, 2015 and 2014, respectively.Provision for Income TaxesThe income tax expense (benefit) for the year ended December 31, 2016 is as follows (in thousands): Current Deferred TotalInternational$627,718 $(14,359) $613,359U.S. Federal63,613 (32,405) 31,208U.S. State(1,175) (65,141) (66,316)Total$690,156 $(111,905) $578,251 The income tax expense (benefit) for the year ended December 31, 2015 is as follows (in thousands): Current Deferred TotalInternational$526,052 $(17,789) $508,263U.S. Federal88,237 (68,696) 19,541U.S. State24,006 25,150 49,156Total$638,295 $(61,335) $576,960 100 The income tax expense (benefit) for the year ended December 31, 2014 is as follows (in thousands): Current Deferred TotalInternational$496,719 $(10,613) $486,106U.S. Federal10,316 47,847 58,163U.S. State28,953 (5,527) 23,426Total$535,988 $31,707 $567,695The U.S. pre-tax loss for the year ended December 31, 2016 compared to the pre-tax income for the year December 31, 2015 is primarily due to theimpairment charge for goodwill of $940.7 million related to OpenTable (see Note 9) and increased interest expense in 2016. Income tax expense on theCompany’s U.S. pre-tax loss for the year ended December 31, 2016 includes the impact of the non-deductible impairment charge of OpenTable goodwill, U.S.income tax on the Company’s international interest income, which increased during the year, and the tax benefits arising from U.S. state tax law changesresulting in a net decrease to deferred tax liabilities, mostly associated with acquired intangible assets.The U.S. pre-tax income for the year ended December 31, 2015, decreased compared to the year ended December 31, 2014, primarily due to higherinterest expense and increased intangible amortization from the OpenTable acquisition. Income tax expense on the Company's U.S. pre-tax income for theyear ended December 31, 2015, includes the impact of increases in state income tax rates on the Company's deferred tax liabilities and U.S. income tax on theCompany's international interest income which increased during the year.Deferred Income TaxesAt December 31, 2016, the Company had approximately $727.8 million of available net operating loss carryforwards ("NOLs") for U.S. federalincome tax purposes, comprised of approximately $22.8 million of NOLs generated from operating losses and approximately $705.0 million of NOLsgenerated from equity-related transactions, including equity-based compensation and stock warrants. The NOLs mainly expire from December 31, 2019 toDecember 31, 2021 and an additional $207 million expires at December 31, 2033. The Company also had approximately $583.9 million of U.S. state NOLs,the majority of which were generated from equity related transactions and mainly expire between December 31, 2020 and December 31, 2034. In addition,the Company has $133.5 million of non-U.S. NOLs, of which $66.1 million expire between December 31, 2019 and December 31, 2023. Further atDecember 31, 2016, the Company had approximately $34.3 million of U.S. research tax credit carryforwards, subject to annual limitation, that mainly expirebetween December 31, 2028 and December 31, 2034, and $26.0 million of federal alternative minimum tax credit carryforwards, that do not expire, that areavailable to reduce future tax liabilities.The utilization of these NOLs, allowances and credits is dependent upon the Company's ability to generate sufficient future taxable income and thetax laws in the jurisdictions where the losses were generated. Because of a 2016 change in state tax law, the Company estimates that approximately $230million of unrecognized state NOLs ($20.7 million tax-effected) generated from equity-related transactions will expire before the Company has the capacityto utilize them. The Company periodically evaluates the likelihood of the realization of deferred tax assets, and reduces the carrying amount of these deferredtax assets by a valuation allowance to the extent it believes a portion will not be realized. The Company considers many factors when assessing thelikelihood of future realization of the deferred tax assets, including its recent cumulative earnings experience by taxing jurisdiction, expectations of futureincome, tax planning strategies, the carryforward periods available for tax reporting purposes, and other relevant factors.101 The tax effects of temporary differences that give rise to significant portions of deferred tax assets and liabilities at December 31, 2016 and 2015 areas follows (in thousands): 2016 2015Deferred tax assets/(liabilities): Net operating loss carryforward — U.S.$15,977 $59,220Net operating loss carryforward — International18,371 18,153Accrued expenses72,631 61,703Stock-based compensation and other stock based payments60,937 77,761Other— 8,001Subtotal167,916 224,838 Discount on convertible notes(77,845) (112,886)Intangible assets and other(740,329) (822,685)Euro denominated debt(117,737) (92,230)Fixed assets(2,245) (3,658)Other(3,958) —Less valuation allowance on deferred tax assets(24,475) (64,845)Net deferred tax liabilities (1)$(798,673) $(871,466) (1) Includes deferred tax assets of $23.7 million and $21.1 million as of December 31, 2016 and 2015, respectively, reported in "Other assets" in theConsolidated Balance Sheets.The valuation allowance on deferred tax assets of $24.5 million at December 31, 2016 includes $4.1 million related to U.S. federal net operating losscarryforwards derived from equity transactions, $18.5 million related to international operations and $1.9 million related to U.S. research credits and capitalloss carryforwards. During the year ended December 31, 2016, the Company utilized the majority of its pre-2006 federal equity NOLs resulting in a $40million decrease in the valuation allowance. Additionally, since January 1, 2006, the Company has generated tax benefits arising from equity transactionsthat are not included in the deferred tax table above in accordance with current accounting principles. Pursuant to the adoption of an accounting updateissued in March 2016, the Company will record a deferred tax asset for approximately $300 million, net of valuation allowances, with a corresponding creditto retained earnings on January 1, 2017, representing the previously unrecognized tax benefit related to equity transactions (see Note 2). It is the practice and intention of the Company to indefinitely reinvest the unremitted earnings of its international subsidiaries outside of the UnitedStates, therefore, at December 31, 2016, no provision has been made for U.S. taxes on approximately $13.0 billion of cumulative unremitted internationalearnings. The Company estimates that the deferred tax liability it would record if such earnings were not indefinitely reinvested internationally isapproximately $2.3 billion as of December 31, 2016.Reconciliation of U.S. Federal Statutory Income Tax Rate to Effective Income Tax RateA significant portion of the Company's taxable earnings are generated in the Netherlands. According to Dutch corporate income tax law, incomegenerated from qualifying innovative activities is taxed at a rate of 5% ("Innovation Box Tax") rather than the Dutch statutory rate of 25%. A portion ofBooking.com's earnings during the years ended December 31, 2016, 2015 and 2014 qualifies for Innovation Box Tax treatment, which had a significantbeneficial impact on the Company's effective tax rate for those years. 102 The effective income tax rate of the Company is different from the amount computed using the expected U.S. statutory federal rate of 35% as a resultof the following items (in thousands): 2016 2015 2014Income tax expense at federal statutory rate$949,633 $1,094,912 $1,046,307Adjustment due to: Foreign rate differential(377,542) (316,078) (289,692)Innovation Box Tax benefit(324,633) (260,193) (233,545)Impairment of goodwill and cost-method investment343,484 — —Other(12,691) 58,319 44,625Income tax expense$578,251 $576,960 $567,695 Uncertain Tax PositionsSee Note 2 for the Company's accounting policy on uncertain tax positions.

The Company does not expect further significant changes in the amount of unrecognized tax benefitsduring the next twelve months. The Company's Netherlands, U.S. federal, Connecticut, Singapore, and U.K. income tax returns, constituting the returns of the major taxingjurisdictions, are subject to examination by the taxing authorities as prescribed by applicable statute. The statute of limitations remains open for: theCompany's Netherlands returns from 2010 and forward; the Company's Singapore returns from 2012 and forward; the Company's U.S. Federal andConnecticut returns from 2013 and forward; and the Company's U.K. returns for the tax years 2008, 2015, and 2016. No income tax waivers have beenexecuted that would extend the period subject to examination beyond the period prescribed by statute in the major taxing jurisdictions in which thecompany is a taxpayer. See Note 14 for more information regarding tax contingencies.14.COMMITMENTS AND CONTINGENCIES Competition ReviewsThe online travel industry has become the subject of investigations by various national competition authorities ("NCAs"), particularly in Europe.The Company is or has been involved in investigations predominately related to whether Booking.com's contractual parity arrangements withaccommodation providers, sometimes also referred to as "most favored nation" or "MFN" provisions, are anti-competitive because they requireaccommodation providers to provide Booking.com with room rates that are at least as low as those offered to other online travel companies ("OTCs") orthrough the accommodation provider's website.In Europe, investigations into Booking.com's price parity provisions were initiated in 2013 and 2014 by NCAs in France, Germany, Italy, Austria,Sweden, Ireland and Switzerland. A number of other NCAs have also looked at these issues. On April 21, 2015, the French, Italian and Swedish NCAs,working in close cooperation with the European Commission, announced that they had accepted "commitments" offered by Booking.com to resolve andclose the investigations in France,103 Italy and Sweden. Under the commitments, Booking.com replaced its existing price parity agreements with accommodation providers with "narrow" priceparity agreements. Under a "narrow" price parity agreement, subject to certain exceptions, an accommodation provider is still required to offer the same orbetter rates on Booking.com as it offers to a consumer directly online, but it is no longer required to offer the same or better rates on Booking.com as it offersto other OTCs. The commitments also allow an accommodation provider to, among other things, offer different terms and conditions (e.g., free WiFi) andavailability to consumers that book with online travel companies that offer lower rates of commission or other benefits, offer lower rates to consumers thatbook through offline channels and continue to discount through, among other things, accommodation loyalty programs, as long as those rates are notpublished or marketed online. The commitments apply to accommodations in France, Italy and Sweden and were effective on July 1, 2015. The foregoingdescription is a summary only and is qualified in its entirety by reference to the commitments published by the NCAs on April 21, 2015.On July 1, 2015, Booking.com voluntarily implemented the commitments given to the French, Italian and Swedish NCAs throughout the EuropeanEconomic Area and Switzerland. Nearly all NCAs in the European Economic Area have now closed their investigations following Booking.com'simplementation of the commitments in their jurisdictions. Booking.com has also recently resolved the concerns of the NCAs in Australia, New Zealand andGeorgia further to agreeing to implement the "narrow" price parity clause in these countries. The Turkish NCA recently imposed fines on Booking.comfollowing an investigation into Booking.com's "wide" parity clauses. Booking.com is in ongoing discussions with various NCAs in other countries regardingtheir concerns. The Company is currently unable to predict the long-term impact the implementation of these commitments will have on Booking.com'sbusiness, on investigations by other countries, or on industry practice more generally.On December 23, 2015, the German NCA issued a final decision prohibiting Booking.com's "narrow" price parity agreements with accommodationsin Germany. The German NCA did not issue a fine, but has reserved its position regarding an order for disgorgement of profits. Booking.com is appealing theGerman NCA's decision. An Italian hotel association has appealed the Italian NCA's decision to accept the commitments by Booking.com.A working group of 10 European NCAs (France, Germany, Belgium, Hungary, Ireland, Italy, the Netherlands, Czech Republic, the United Kingdomand Sweden) was established by the European Commission in December 2015 to monitor the effects of the narrow price parity clause in Europe. This workinggroup (the "ECN Working Group") issued questionnaires during 2016 to online travel agencies, including Booking.com and Expedia, meta-search sites andhotels about the narrow price parity clause. On February 17, 2017 the ECN Working Group issued a statement that it would publish its report soon and that ithad decided to keep the sector under review and re-assess the competitive situation in due course. Separately, the French NCA, which is conducting its ownreview of the effects of the narrow price parity clause, on February 9, 2017, issued a report stating that it has not ruled out the possibility of issuing anopinion at its own initiative if a change in competition requires it, and that it would continue to contribute actively to the ECN Working Group process.The Company is unable to predict how these appeals and the remaining investigations in other countries will ultimately be resolved, or whetherfurther action in Europe will be taken as a result of the working group's findings. Possible outcomes include requiring Booking.com to amend or remove itsrate parity clause from its contracts with accommodation providers in those jurisdictions and/or the imposition of fines. The Company is unable to predict theimpact these possible outcomes might have on its business.In August 2015, French legislation known as the "Macron Law" became effective. Among other things, the Macron Law makes price parityagreements illegal, including the "narrow" price parity agreements agreed to by the French NCA in April 2015. Legislation in Austria prohibiting "narrow"price parity agreements (including the narrow parity clause) became effective on December 31, 2016. Similar legislation was approved by the Italian Senatein June 2016 but not ultimately passed, and could be introduced again in 2017. A motion to prohibit the narrow price parity clause has also been proposed inSwitzerland. It is not yet clear how the Macron Law and the Austrian legislation or the proposed Italian and Swiss legislation may affect the Company'sbusiness in the long term in France, Austria, Italy and Switzerland, respectively.Competition-related investigations, legislation or issues could also give rise to private litigation. For example, Booking.com is involved in privatelitigation in Sweden related to its "narrow" price parity provisions. We are unable to predict how this litigation will be resolved, or whether it will impactBooking.com's business in Sweden.Litigation Related to Travel Transaction Taxes The Company and certain third-party OTCs are currently involved in approximately thirty lawsuits, including certified and putative class actions,brought by or against U.S. states, cities and counties over issues involving the payment of travel transaction taxes (e.g., hotel occupancy taxes, excise taxes,sales taxes, etc.) related to the priceline.com business. Generally,104 the complaints allege, among other things, that the OTCs violated each jurisdiction's respective relevant travel transaction tax ordinance with respect to thecharge and remittance of amounts to cover taxes under each law. The Company believes that the laws at issue generally do not apply to the services itprovides, namely the facilitation of travel reservations, and, therefore, that it does not owe the taxes that are claimed to be owed. However, the Company hasbeen involved in this type of litigation for many years, and state and local jurisdictions where these issues have not been resolved could assert that theCompany is subject to travel transaction taxes and could seek to collect such taxes, retroactively and/or prospectively. From time to time, the Company hasfound it expedient to settle claims pending in these matters without conceding that the claims at issue are meritorious or that the claimed taxes are in fact dueto be paid. The Company may also settle current or future travel transaction tax claims.On August 5, 2016, the tax appeal court of the State of Hawaii ruled that online travel companies, including the Company, owe General Excise Tax(GET) on the gross amounts collected from consumers on rental car reservations. The tax appeal court rejected the online travel companies’ arguments thatGET applies only to amounts retained by online travel companies and does not include amounts paid to rental car company suppliers. The online travelcompanies argued that GET should not apply to gross amounts charged to consumers for rental car reservations pursuant to the 2015 decision of the HawaiiSupreme Court in Travelocity.com, L.P., et al. v. Director of Taxation that GET applies to amounts retained by online travel companies for hotel reservationsand not for gross amounts charged to consumers. The Company intends to appeal the tax appeal court decision to the Hawaii appellate courts. The Companymust pay the amount of the judgment, which has not yet been entered and which we believe will be immaterial to our financial condition, results ofoperations and cash flows, in order to appeal the decision.Litigation is subject to uncertainty and there could be adverse developments in these pending or future cases and proceedings. An unfavorableoutcome or settlement of pending litigation may encourage the commencement of additional litigation, audit proceedings or other regulatory inquiries andalso could result in substantial liabilities for past and/or future bookings, including, among other things, interest, penalties, punitive damages and/orattorneys’ fees and costs. An adverse outcome in one or more of these unresolved proceedings could have an adverse effect on the Company's results ofoperations or cash flows in any given operating period. However, the Company believes that even if the Company were to suffer adverse determinations inthe near term in more of the pending proceedings than currently anticipated, given results to date it would not have a material impact on its liquidity orfinancial condition.As a result of the travel transaction tax litigation generally and other attempts by U.S. jurisdictions to levy similar taxes, the Company hasestablished an accrual (including estimated interest and penalties) for the potential resolution of issues related to travel transaction taxes in the amount ofapproximately $27 million at both December 31, 2016 and 2015. The Company's legal expenses for these matters are expensed as incurred and are notreflected in the amount accrued. The actual cost may be less or greater, potentially significantly, than the liabilities recorded. An estimate for a reasonablypossible loss or range of loss in excess of the amount accrued cannot be reasonably made.Patent InfringementOn February 9, 2015, International Business Machines Corporation ("IBM") filed a complaint in the U.S. District Court for the District of Delawareagainst The Priceline Group Inc. and its subsidiaries KAYAK Software Corporation, OpenTable, Inc. and priceline.com LLC (the "Subject Companies"). In thecomplaint, IBM alleges that the Subject Companies have infringed and continue to willfully infringe certain IBM patents that IBM claims relate to thepresentation of applications and advertising in an interactive service, preserving state information in online transactions and single sign-on processes in acomputing environment and seeks unspecified damages (including a request that the amount of compensatory damages be trebled), injunctive relief andcosts and reasonable attorneys’ fees. The Subject Companies believe the claims to be without merit and are contesting them. The Subject Companies askedthe court to dismiss the case due to lack of patentable subject matter in the asserted patents, and on March 30, 2016 that motion was denied without prejudiceto refiling later in the case. Concurrently with the litigation, the Subject Companies filed two Inter Partes Review ("IRP") petitions and four Covered BusinessMethod (“CBM”) petitions for the patents-in-suit with the U.S. Patent and Trademark Office (the "PTAB"). The PTAB denied one of the IPR petitions andgranted one of the IPR petitions, and denied the four CBM petitions. Expert discovery has concluded and summary judgment briefing has begun. Trial in theDistrict Court is scheduled for August 2017. The Company does not believe a loss contingency is probable or reasonably estimable and therefore has notrecorded a liability for this matter.105 French and Italian Tax MattersFrench tax authorities recently concluded an audit of Booking.com that started in 2013 of the years 2003 through 2012. They are asserting thatBooking.com has a permanent establishment in France and are seeking to recover what they claim are unpaid income taxes and value-added taxes. InDecember 2015, the French tax authorities issued Booking.com assessments for approximately 356 million Euros, the majority of which would representpenalties and interest. The Company believes that Booking.com has been, and continues to be, in compliance with French tax law, and the Company intendsto contest the assessments. If the Company is unable to resolve the matter with the French authorities, it would expect to challenge the assessments in theFrench courts. In order to contest the assessments in court, the Company may be required to pay, upfront, the full amount or a significant part of any suchassessments, though any such payment would not constitute an admission by it that it owes the taxes. At the end of 2016, French authorities announced theirintention to also audit the tax years 2013 to 2015, which could result in additional assessments.Italian tax authorities have initiated a process to determine whether Booking.com should be subject to additional tax obligations in Italy. Italian taxauthorities may determine that the Company owes additional taxes, and may also assess penalties and interest. The Company believes that it has been, andcontinues to be, in compliance with Italian tax law.OtherThe Company accrues for certain legal contingencies where it is probable that a loss has been incurred and the amount can be reasonably estimated.Such accrued amounts are not material to the Company's consolidated balance sheets and provisions recorded have not been material to the Company'sconsolidated results of operations or cash flows. An estimate for a reasonably possible loss or range of loss in excess of the amount accrued cannot bereasonably made.From time to time, the Company has been, and expects to continue to be, subject to legal proceedings and claims in the ordinary course of business,including claims of alleged infringement of third-party intellectual property rights. Such claims, even if not meritorious, could result in the expenditure ofsignificant financial and managerial resources, divert management's attention from the Company's business objectives and adversely affect the Company'sbusiness, results of operations, financial condition and cash flows.Contingent Consideration for Business Acquisitions (see Note 18)Employment Contracts The Company has employment agreements with certain members of senior management that provide for cash severance payments of up toapproximately $17.8 million, accelerated vesting of equity instruments, including without limitation, stock options, restricted stock units and performanceshare units upon, among other things, death or termination without "cause" or "good reason," as those terms are defined in the agreements. In addition, certainof the agreements provide for the extension of health and insurance benefits after termination for periods up to two years. Building ConstructionIn September 2016, the Company signed a turnkey agreement to construct an office building in the Netherlands, which will be the futureheadquarters of the Booking.com business.
