Booking (BKNG) 10-K2020 FY Annual report

 

 

The COVID-19 pandemic has had a profound impact on our business, employees, partners, communities and stockholders. Although there was a significant decline in our business in 2020 as a result of the COVID-19 pandemic, we remain confident that the travel industry will recover when travelers feel safe to travel once again. In the beginning of the crisis, our priorities included the health and safety of our employees and stabilizing our business from the immediate shock of the pandemic by working with customers and partners to address unprecedented levels of cancellations. We also took numerous actions in response to the pandemic, including steps to increase our financial liquidity, reduce costs, restructure our operations to address our near- to medium-term business expectations and ensure we are well-positioned to capture travel demand when it returns so we can emerge from this crisis on a strong footing and work on extending our leadership position. While the timing of the recovery of the travel industry remains uncertain, we believe that demand for our services will return when government restrictions are lifted and people are confident it is once again safe to travel.

As a result, our mission to make it easier for everyone to experience the world remains unchanged. We seek to empower people to cut through travel barriers, such as money, time, language and overwhelming options, so they can use our services to easily and confidently get where they want to go, stay where they want to stay, dine where they want to dine, pay how they want to pay and experience what they want to experience. We connect consumers wishing to make travel reservations with providers of travel services around the world through our online platforms. Through one or more of our brands, consumers can: book a broad array of accommodations (including hotels, motels, resorts, homes, apartments, bed and breakfasts, hostels and other properties); make a car rental reservation or arrange for an airport taxi; make a dinner reservation; or book a flight, cruise, vacation package, tour or activity. Consumers can also use our meta-search services to easily compare travel reservation information, such as airline ticket, hotel reservation and rental car reservation information, from hundreds of online travel platforms at once. In addition, we offer various other services to consumers and partners, such as certain travel-related insurance products and restaurant management services to restaurants.

We offer these services through six primary consumer-facing brands: Booking.com, Priceline, agoda, Rentalcars.com, KAYAK and OpenTable. While historically our brands operated on a largely independent basis and many of them focused on a particular service (e.g., accommodation reservations) or geography, we continue to increase the collaboration, cooperation and interdependency among our brands in our efforts to provide consumers with the best and most comprehensive services. We also seek to maximize the benefits of our scale by sharing resources and technological innovations, co-developing new services and coordinating activities in key markets among our brands. For example, Booking.com, the world’s leading brand for booking online accommodation reservations (based on room nights booked), offers rental car and other ground transportation services, flights, tours and activities, restaurant reservations and other services, many of which are supported by our other

Our business is driven primarily by international results, which consist of the results of Booking.com, agoda and Rentalcars.com and the international businesses of KAYAK and OpenTable. This classification is independent of where the consumer resides, where the consumer is physically located while using our services or the location of the travel service provider or restaurant. For example, a reservation made through Booking.com at a hotel in New York by a consumer in the United States is part of our international results. During the year ended December 31, 2020, our international business (the substantial majority of which is generated by Booking.com) represented approximately 88% of our consolidated revenues. A significant majority of our revenues, including a significant majority of our international revenues, is earned in connection with facilitating accommodation reservations. See Note 18 to the Consolidated Financial Statements for more geographic information.

Our common stock is listed on the NASDAQ Global Select Market under the symbol "BKNG."  We refer to our company and all of our subsidiaries and brands collectively as "Booking Holdings," the "Company," "we," "our" or "us."

For the year ended December 31, 2020, we had revenues of $6.8 billion, which we classify as "agency" revenues, "merchant" revenues and "advertising and other" revenues.

We aim to achieve our mission to make it easier for everyone to experience the world through global leadership in online travel and restaurant reservation and related services by striving to:

We have established widely used and recognized e-commerce brands through marketing and promotional campaigns. Historically, our marketing expenses increased significantly, however, we experienced more moderate growth rates in recent years, and since the COVID-19 pandemic, our marketing expenses have declined significantly. We have invested considerable resources in the establishment and maintenance of our brands, and we intend to continue to invest resources in marketing and other brand building efforts to preserve and enhance consumer awareness of our brands when and to the extent we deem appropriate, in particular as the COVID-19 pandemic subsides and consumers begin to travel again.

We compete globally with both online and traditional travel and restaurant reservation and related services. The markets for the services we offer are intensely competitive, constantly evolving and subject to rapid change, and current and new competitors can launch new services at a relatively low cost. Some of our current and potential competitors, such as Google, Apple, Alibaba, Tencent, Amazon and Facebook, have significantly more customers or users, consumer data and financial and other resources 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 compete more effectively with us. For example, Google has entered various aspects of the online travel market and has grown rapidly in this area, including by offering a flight meta-search product ("Google Flights"), a hotel meta-search product ("Google Hotel Ads"), a vacation rental meta-search product, its "Book on Google" reservation functionality, Google Travel, a planning tool that aggregates its flight, hotel and packages products in one website and by integrating its hotel meta-search products and restaurant information and reservation products into its Google Maps app. In addition, Amazon has experimented with online travel in the past and continues to experiment in this area, such as by partnering with travel companies to offer its customers travel products, including a partnership with Booking.com to provide travel deals to Amazon Prime users in certain countries.

 

As a global online travel company, our ability to provide our services and any future services is affected by legal regulations (including laws, ordinances, rules, licensing requirements and other requirements and regulations) of national and local governments and regulatory authorities around the world, many of which are evolving and subject to the possibility of new or revised interpretations. Examples of these laws and regulations, which vary and sometimes conflict, include the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and local laws which also prohibit corrupt payments to governmental officials or third parties, data privacy requirements, labor relations laws, non-discrimination, human rights or anti-human trafficking laws and regulations, such as the U.K. Modern Slavery Act 2015, tax laws, anti-trust or competition laws, U.S., E.U. or U.N. sanctioned country or sanctioned persons mandates and consumer protection laws. Violations of these laws and regulations could result in fines, penalties and/or criminal sanctions against us, our officers or our employees and/or prohibitions on the conduct of our business. Any such violations could also result in prohibitions on our ability to offer our

Our business is supported by multiple systems and platforms, which were designed with an emphasis on scalability, performance, reliability, redundancy and security.  These systems and platforms are generally independent among our brands, though some have become increasingly connected or shared.  Our software systems, platforms and architecture use a variety of widely-used software tools and database systems. 

These internal systems and platforms are designed to include open application protocol interfaces that can provide connectivity to vendors in the industries in which we operate.  These include large global systems, such as accommodation, airline ticket and rental car reservation systems and financial service providers, as well as individual accommodation service providers, such as independent 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, the Netherlands, Germany, Singapore, Hong Kong and four locations in the United States, each of which provides network connectivity, networking infrastructure and 24-hour monitoring and engineering support typical of hosted data centers.  All data center facilities have a continuous power supply system, generators, redundant servers and multiple back-up systems.  Although we take steps to mitigate the effects of any loss or reduction in

We provide customer service through a mix of in-house call centers and outsourced third-party services.

 

In recent years, and prior to the COVID-19 pandemic, the majority of our gross bookings are generated in the first half of the year, as consumers plan and reserve their spring and summer vacations in Europe and North America. However, we generally recognize revenue from these bookings when the travel begins (at "check-in"), which can be in a quarter other than when the associated reservations are booked. In contrast, we expense the substantial majority of our marketing activities as the expense is incurred, which, in the case of performance marketing in particular, is typically in the quarter in which associated reservations were booked. As a result of this timing difference between when we recorded marketing expense and when we recognized associated revenue, we had our highest levels of profitability in the third quarter of the year, which is when there were the highest levels of accommodation check-ins for the year for our European and North American markets. The first quarter of the year was typically our lowest level of profitability and highest level of volatility in earnings growth rates due to these seasonal timing factors. The COVID-19 pandemic impacted seasonality in 2020; for example, we witnessed a higher share of travel being booked during the second and third quarters as well as a higher share of stays during the third quarter than in prior years. We cannot currently predict travel patterns given the COVID-19 pandemic, and we may not experience typical seasonality effects on our business in 2021. Additionally, in the third and fourth quarters, we saw a significant contraction of the booking window versus the comparable prior-year period as an increased percentage of newly-booked room nights were made for travel that was to occur close to the time of booking. We expect that the length of the booking window will be volatile and difficult to predict throughout the duration of the COVID-19 pandemic. Future changes in the length of the booking window will affect the degree to which our gross bookings and revenues occur in the same period and, as a result, whether our gross bookings growth rates and revenue growth rates converge or diverge. For additional information regarding factors affecting the seasonality of our business, see Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations - Seasonality and Other Timing Matters.

We believe our employees are one of the most important assets we have to further our mission to make it easier for everyone to experience the world. In order to continue to deliver on this mission, our goal is to attract, develop and retain highly-skilled talent with a significant focus on a diverse workforce operating in an inclusive environment. In the past year, the COVID-19 pandemic has had a significant impact on our workforce and our human capital management.

Part of our strategy is to operate multiple brands to appeal to different consumers, pursue different marketing and business strategies, encourage experimentation and innovation, provide different service offerings and focus on different markets. While we continue to increase the collaboration, cooperation and interdependency among our brands, this model inherently results in diversity of culture among our brands, which may manifest in different approaches to human capital management in certain areas.

At December 31, 2020, we employed approximately 20,300 employees, of which approximately 3,400 were based in the United States and approximately 16,900 were based outside the United States. Approximately 99% of our employees are full-time employees. We also retain independent contractors, including to support our customer service, website content translation and system support functions.

As a result of the COVID-19 pandemic, we made the difficult decision to restructure our workforce to align our total cost structure with our expectations of reduced near- to medium-term market demand for travel and restaurant reservation services. Although we took various steps to maintain jobs and reduce the need for workforce reductions, including participating in various wage assistance programs, our total workforce decreased by approximately 23% year-over-year as of December 31, 2020 primarily due to a combination of our restructuring actions and attrition. Throughout the restructuring process, we have prioritized treating our colleagues with fairness and respect by, among other things, offering severance packages, an Employee Assistance Program with access to counseling services and job placement support.

We believe that a diverse workforce operating in an inclusive environment is critical to leveraging our human capital to achieve our long-term strategic goals, particularly in the technology industry where many populations remain underrepresented. We strive for our leadership and workforce to reflect the broad spectrum of customers and partners we work with throughout the world because we believe this is the best way for us to connect with the broad viewpoints, backgrounds and experiences of our customers and partners. In addition, we maintain a workplace that embraces the different cultures and practices of our diverse employees and is consistent with our Code of Conduct. We believe we abide by the laws and regulations that govern our employment practices and we prohibit unlawful discrimination of any type.

As of December 31, 2020, approximately 50% of our employees were women, approximately 22% of our technology positions were filled by women and approximately 30% of our extended leadership team (which includes the Company's senior leadership and extends 1 to 4 levels below the chief executive officer of each brand company (depending on the number of employees within each brand)) were women. We are committed to pay equity, regardless of gender, race or ethnicity. With the help of our independent compensation consultant, Mercer, we conduct pay equity studies every other year, and in the off years, we work on remediation plans to address outliers.

We support equality and inclusiveness across our workforce through various initiatives at all the brand companies. For example, Booking.com has several employee resource groups including: B.Able to support employees with differing physical and mental abilities; B.Bold to support the Black and persons-of-color (POC) community; and B.Equal to support gender equality. Agoda supports employee resource groups aimed at fostering greater workplace inclusion with initiatives such as the Agoda Colors and Women at Agoda. At Priceline, the Women Impacting Priceline resource group is empowering women to champion their professional development and improve gender intelligence. We are proud of the progress we have made in this space and recognize we can always improve. Part of advancing these initiatives involves facilitating a pipeline of candidates for open positions that are representative of the spectrum of communities we serve. KAYAK and OpenTable are diversifying their job board postings and partnering with underrepresented groups such as historically Black colleges and universities in the United States. Priceline is also partnering with organizations to access more diverse candidates and has rewritten job descriptions to be more appealing to a broader audience of candidates. Additionally, we are entering our fifth year of operating our Women in Leadership program, which is a Company-wide initiative designed to support the advancement and development of high-performing women within the Company with the goal of building and enabling gender diversity in our executive pipeline.

We work diligently to attract the best and most innovative talent from a diverse range of sources to grow our business and achieve our long term strategic goals. We believe that we offer a rich culture where employees feel included and empowered to do their best work with opportunities to grow as well as competitive compensation and benefits. For example, while the specifics can vary by brand, in the United States our employee benefit plans generally include: coverage for infertility treatments, gender reassignment surgery, gender-neutral domestic partner benefits and paid parental leave.

Despite the challenges of shifting the vast majority of our workforce to work-from-home due to the COVID-19 pandemic, we continue to prioritize and invest in creating opportunities for employees to grow and build their careers through training and development programs. These include offering tailored learning opportunities to enable employees to upskill while at work and driving deliberate career conversations between employees and their managers, as well as executive talent and succession planning.

We measure organizational culture and engagement to build on the competencies that are important for our future success. The disruptions stemming from the COVID-19 pandemic have presented particularly unique challenges to keeping employees engaged and supported at work. We shifted our approach to employee engagement in response to changing employee needs in a mostly-virtual workplace, by, for example, providing regular video-based CEO updates and virtual mental wellness workshops. We regularly touch base with our employees through formal engagement surveys, work-from-home

Throughout the crisis of the COVID-19 pandemic, we have prioritized the health and safety of our employees. We recognize that our employees have been faced with unprecedented challenges both professionally and personally, and as a result, we have increased the frequency of scheduled communication between management and the workforce, offered additional unscheduled holidays, shifted the vast majority of our workforce to work-from-home, offered additional meditation and wellness benefits to support employee mental well-being, encouraged alterations to meeting schedules during the work week to combat “virtual meeting fatigue” and designated specific days or periods in the year as “quiet periods” in recognition of the need for employees to rest and recharge.

Although we have works councils or employee representatives in certain countries, our U.S. employees are not represented by a labor union and are not covered by a collective bargaining agreement. Throughout the restructuring process, we worked in close collaboration with works councils, employee representatives and other organizations in the relevant jurisdictions. We have never had a work stoppage and we consider our relations with our employees to be good.

In response to the outbreak of the novel strain of the coronavirus, COVID-19 (the "COVID-19 pandemic"), many governments around the world have implemented, and continue to implement, a variety of measures to reduce the spread of COVID-19, including travel restrictions and bans, instructions to residents to practice social distancing, curfews, quarantine advisories, including quarantine restrictions after travel in certain locations, shelter-in-place orders, required closures of non-essential businesses and additional restrictions on businesses as part of re-opening plans. These government mandates have forced many of the partners on whom our business relies, including hotels and other accommodation providers, airlines and

Our business is dependent on the availability of a large number of accommodations (particularly independently-owned accommodations) and restaurants, and on the ability of consumers to travel to such accommodations and restaurants on airlines, railways and rental cars. The ability of consumers to travel internationally has been significantly impacted by the various travel restrictions between countries, including for example, the restrictions on travel between the European Union and the United States. We do not expect economic and operating conditions for our business to improve until consumers are once again willing and able to travel, and our travel service provider and restaurant partners are once again willing and able to serve those

To the extent that the COVID-19 pandemic continues to adversely affect our business and financial performance, it may also have the effect of heightening many of the other risks identified in this section, such as those relating to our substantial amount of outstanding indebtedness.

Certain governments have passed or are considering legislation to help businesses during the COVID-19 pandemic through loans, wage subsidies, tax relief or other financial aid, and some of these governments have extended or are considering extending these programs. We have participated in several of these programs, including the Netherlands' wage subsidy program and the United Kingdom's job retention scheme. In some cases, these programs restrict the ability of participating companies to take certain actions, such as restructurings, while participating in the program, though we are not currently under any such restrictions. Additionally, in certain jurisdictions, there has been public scrutiny of government aid beneficiaries, including us, and as a result, our reputation could be harmed by having participated in these programs or participating in the future.

As a result of the deterioration of our business due to the COVID-19 pandemic, we evaluated goodwill, long-term investments and long-lived assets for possible impairment as of March 31, 2020. As a result of this evaluation, we determined that our goodwill relating to OpenTable and KAYAK experienced a decline in value due to the COVID-19 pandemic, and therefore we recognized a goodwill impairment charge of $489 million (which is non-deductible for income tax purposes) as of March 31, 2020. In addition, we recorded an impairment charge of $100 million at March 31, 2020 related to our investment in Didi Chuxing due to the impact of the COVID-19 pandemic on the business of the investee and our estimate of the resulting decline in the value of the investment. As of September 30, 2020, we performed our annual goodwill impairment testing. As a result of this testing, we recognized an additional goodwill impairment charge of $573 million (which is non-deductible for income tax purposes) for the three months ended September 30, 2020 relating to OpenTable and KAYAK. The determination of the fair value reflects numerous assumptions that are subject to various risks and uncertainties, including key assumptions regarding OpenTable and KAYAK’s expected growth rates and operating margins, expected length and severity of the impact from the COVID-19 pandemic and the shape and timing of the subsequent recovery, the performance of the businesses during and following the COVID-19 pandemic, as well as other key assumptions with respect to matters outside of our control, such as discount rates and market comparables. The evaluations required significant judgments and estimates and actual results could be materially different than those judgments and estimates utilized in the fair value estimates. Future events and changing market conditions may lead us to re-evaluate the assumptions reflected in the current forecast disclosed above, particularly the assumptions related to the length and severity of the COVID-19 pandemic, the shape and timing of the subsequent recovery and the performance of the businesses during and following the COVID-19 pandemic, which may result in a need to recognize an additional goodwill impairment charge, which could have a material adverse effect on our results of operations. See Notes 5, 6 and 11 to the Consolidated Financial Statements for additional information related to the impairment charges.

In addition, given the severe downturn in the global travel industry and the financial difficulties faced by many of our travel service provider and restaurant partners as a result of the COVID-19 pandemic, we have increased our provision for expected credit losses on receivables from and cash advances made to our travel service provider and restaurant partners. For the year ended December 31, 2020, there was a $161 million increase in expected credit loss expense compared to the same period in the prior year. Moreover, due to the high level of cancellations of existing reservations, we have incurred, and may continue to incur, higher than normal cash outlays to refund consumers for prepaid reservations. In some instances, we do not estimate a recovery of prepayment already made to a travel service provider where we have agreed to provide free cancellations to customers for non-refundable reservations, and this has resulted in an aggregate reduction in revenue of $44 million for the year ended December 31, 2020. Any additional significant increase in our provision for expected credit losses on receivables from and cash advances made to travel service provider and restaurant partners, and any additional significant increase in cash outlays to refund consumers, would have a corresponding negative effect on our results of operations and related cash flows.

Due to the impact of the COVID-19 pandemic on our business volumes, we took actions to reduce the size of our workforce, and there could be further reductions in the size of our workforce and/or consolidations to optimize efficiency and reduce costs. See Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations - Trends for more information on the workforce reductions. We have incurred and expect to incur charges related to the reductions in our workforce, changes in our facilities requirements, contract terminations and other non-cash charges, and there could be unanticipated costs in the future. Implementation of these restructuring actions presents several significant risks, including the potential negative impact on employee morale and productivity, the loss of talented employees that we would not otherwise want to lose, difficulty retaining valuable key employees that have not been terminated, adverse impact on our culture, diversion of attention away from operating our business, public scrutiny, personnel capacity constraints, adverse effects on our internal control environment, actual or perceived disruption of service to our customers and hampering of our ability to grow, develop innovative products and compete, any of which could adversely impact our business and reputation. If we do not successfully manage the restructurings, the anticipated efficiencies and cost savings may be delayed or not realized. Risks associated with managing any restructurings effectively include unforeseen delays in the implementation of workforce reductions, delays in completing required consultations with works councils or other relevant organizations or in obtaining any required approvals, regulatory impediments or litigation. Any of these risks associated with the implementation or management of the restructurings could adversely impact our business, results of operations and/or reputation.

Our financial results and prospects are almost entirely dependent upon the sale of travel services. Travel, including accommodation (including hotels, motels, resorts, homes, apartments and other unique places to stay), rental car and airline ticket reservations, is significantly dependent on discretionary spending levels. As a result, sales of travel services decline during general economic downturns and recessions and times of political or economic uncertainty, such as currently being experienced due to the COVID-19 pandemic, as consumers engage in less discretionary spending, are concerned about unemployment or inflation, have reduced access to credit or experience other concerns or effects that reduce their ability or willingness to travel.

Perceived or actual adverse economic conditions, including slow, slowing or negative economic growth, high or rising unemployment rates, inflation and weakening currencies, and concerns over government responses such as higher taxes or tariffs, increased interest rates and reduced government spending have impaired and could in the future impair consumer spending and adversely affect travel demand.

Political uncertainty, conditions or events can also negatively affect consumer spending and adversely affect travel demand. In the past, and prior to the significantly changed circumstances brought on by the onset of the COVID-19 pandemic, we experienced volatility in transaction growth rates, increased cancellation rates and weaker trends in accommodation average daily rates ("ADRs") across many regions of the world, particularly in those countries that appear to be most affected by economic and political uncertainties, which we believed were due at least in part to these macro-economic conditions and concerns. Further economic or political disruptions beyond those resulting from the COVID-19 pandemic could cause, contribute to or be indicative of deteriorating macro-economic conditions, which in turn could negatively affect travel or the travel industry in general and therefore have an adverse impact on our results of operations. While lower occupancy rates have historically 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 effect on our accommodation reservation business and on our revenues and results of operations. As a result of the COVID-19 pandemic and its material adverse impact on travel, we have generally seen a significant decrease in occupancy rates and ADRs.

These and other macro-economic uncertainties, such as oil prices, geopolitical tensions and differing central bank monetary policies, have led to significant volatility in the exchange rates between the U.S. Dollar and the Euro, the British Pound Sterling and other currencies. Significant fluctuations in foreign currency exchange rates, stock markets and oil prices can also impact consumer travel behavior. For example, although lower oil prices may lead to increased travel activity as consumers could have more discretionary funds and airline fares decrease, declines in oil prices may be indicative of broader macro-economic weakness, which in turn could negatively affect the travel industry, our business and results of operations. Conversely, higher oil prices may result in higher airfares and decreased travel activity, which can negatively affect our business and results of operations.

As a result of the United Kingdom leaving the European Union ("Brexit"), we anticipate that we will face new regulatory costs and challenges as U.K. regulations and policies diverge from those of the European Union or if additional business licenses are required. Since some of the details of the United Kingdom's exit from the European Union continue to unfold, we are unable to predict all of the effects Brexit will have on our business and results of operations.

The uncertainty of macro-economic factors and their impact on consumer behavior, which may differ across regions, makes it more difficult to forecast industry and consumer trends and the timing and degree of their impact on our markets and business, which in turn could adversely affect our ability to effectively manage our business and adversely affect our results of operations.

In addition to the impact of the COVID-19 pandemic described earlier in these Risk Factors, other events beyond our control, such as oil prices, stock market volatility, terrorist attacks, changing, unusual or extreme weather or natural disasters such as earthquakes, hurricanes, tsunamis, floods, fires, droughts and volcanic eruptions (whether due to climate change or otherwise), travel-related health concerns including pandemics and epidemics such as coronaviruses, Ebola and Zika, political instability, changes in economic conditions, wars and regional hostilities, imposition of taxes, tariffs or surcharges by regulatory authorities, changes in trade policies or trade disputes, changes in immigration policies or other travel restrictions, travel-related accidents or increased focus on the environmental impact of travel, have previously and may in the future disrupt travel, limit the ability or willingness of travelers to visit certain locations or otherwise result in declines in travel demand and adversely affect our business and results of operations. Because these events or concerns, and the full impact of their effects, are largely unpredictable, they can dramatically and suddenly affect travel behavior by consumers, and therefore demand for our services and our relationships with travel service providers and other partners, any of which can adversely affect our business and results of operations.

We compete globally with both online and traditional travel and restaurant reservation and related services. The markets for the services we offer are intensely competitive, constantly evolving and subject to rapid change, and current and new competitors can launch new services at a relatively low cost. Some of our current and potential competitors, such as Google, Apple, Alibaba, Tencent, Amazon and Facebook, have significantly more customers or users, consumer data and financial and other resources 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 compete more effectively with us. For example, Google has entered various aspects of the online travel market and has grown rapidly in this area, including by offering a flight meta-search product ("Google Flights"), a hotel meta-search product ("Google Hotel Ads"), a vacation rental meta-search product, its "Book on Google" reservation functionality, Google Travel, a planning tool that aggregates its flight, hotel and packages products in one website, and by integrating its hotel meta-search products and restaurant information and reservation products into its Google Maps app. In addition, Amazon has experimented with online travel in the past and continues to experiment in this area, such as by partnering with travel companies to offer its customers travel products, including a partnership with Booking.com to provide travel deals to Amazon Prime users in certain countries. Moreover, as the economy and the travel industry recover from the impact of the COVID-19 pandemic, the structure of the travel industry or consumer preferences could change in ways that could disadvantage us and benefit certain of our existing competitors or new entrants. For example, as a result of the COVID-19 pandemic and the resulting international travel restrictions and social distancing practices, there has been a shift in favor of domestic travel and alternative accommodations. This shift could benefit competitors that are more well established in domestic markets and alternative accommodations than we are. As a result, our historical strengths may not provide the competitive advantages that they did prior to the pandemic. If we are unable to successfully adapt to any changes in how the travel industry operates or to changes in the ways in which consumers purchase travel services, our ability to compete, and therefore our business and results of operations, would be adversely affected.

Google, the world's largest search engine and one of the world's largest companies and other large, established companies with substantial resources and expertise in developing online commerce and facilitating internet traffic offer travel or travel-related search, meta-search and/or reservation booking services and may create additional inroads into online travel. Google's travel meta-search services, Google Hotel Ads and Google Flights, have grown rapidly and have achieved significant market share in a relatively short time. Meta-search services leverage their search technology to aggregate travel search results for the consumer's specific itinerary across travel service providers (e.g., accommodations, rental car companies or airlines), online travel companies ("OTCs") and other online platforms and, in many instances, compete directly with us for customers. Meta-search services intend to appeal to consumers by showing broader travel search results than may be available through OTCs or other online platforms, which could lead to travel service providers or others gaining a larger share of search traffic. Google leverages its general search business to promote its meta-search offerings by showing meta-search results at the top of its organic search results. Further, TripAdvisor and trivago, two other leading meta-search companies, support their meta-search services with significant marketing efforts. Through our KAYAK meta-search service, we compete directly with these and other meta-search services. If we are unable to effectively compete with these companies, our business and results of operations could be harmed.

Meta-search services may evolve into more traditional OTCs by offering consumers the ability to make travel reservations directly through their platforms. For example, TripAdvisor allows consumers to make a reservation at some accommodations while staying on TripAdvisor through its "Instant Booking" offering, which includes participation by many of the leading global hotel chains. Google also provides reservation services through "Book on Google." To the extent we participate in any such offerings provided by meta-search services, resulting reservations could be less profitable and could cannibalize business that would otherwise come directly to us or through other more profitable channels. If consumers book travel services through a service such as TripAdvisor's Instant Booking, Google's "Book on Google," a meta-search website or directly with a travel service provider after visiting a meta-search platform or using a meta-search utility on a traditional search

Over the years, there has been a proliferation of new channels through which accommodation providers can offer reservations as the market for travel services has evolved. For example, companies such as Airbnb and Expedia Group offer services providing alternative accommodation property owners, particularly individuals, an online place to list their accommodations where travelers can search and book such properties and compete directly with our alternative accommodation services. In addition, Airbnb, which owns HotelTonight, offers some hotel reservations through its online platforms. Companies specializing in one type of travel service or product could expand their offerings to compete with us more broadly. Further, meta-search services 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 brand to drive consumers directly to its platform. New travel-related services are frequently being introduced to the market. For example, in 2019, Google launched Google Travel, which combines its hotel, flight and packages offerings into one website with trip-planning tools. Some of our competitors and potential competitors offer a variety of online services, such as food delivery, shopping, gaming or search services, many of which are used by consumers more frequently than online travel services. As a result, a competitor or potential competitor that has established other, more frequent online interactions with consumers may be able to more easily or cost-effectively acquire customers for its online travel services than we can. For example, some competitors or potential competitors with more frequent online interactions with consumers are seeking to create "super-apps" where consumers can use many online services without leaving that company's app, in particular in markets such as Asia where online activity (including e-commerce) is conducted primarily through apps on mobile devices. If any of these platforms are successful in offering new travel-related services or services similar to ours to consumers who would otherwise use our platforms or if we are unable to offer our services to consumers within these super-apps, our customer acquisition efforts could be less effective and our customer acquisition costs, including our marketing expenses, could increase, either of which would harm our business and results of operations.

Although we believe that providing an extensive collection of properties, excellent customer service and an intuitive, easy-to-use consumer experience are important factors influencing a consumer's decision to make a reservation, for many consumers, particularly in certain markets, the price of the travel service is the primary factor determining whether a consumer will book a reservation. As a result, it is increasingly important to offer travel services, such as accommodation reservations, at competitive prices, whether through discounts, coupons, closed-user group rates or loyalty programs, or otherwise. Discounting and couponing coupled with a high degree of consumer shopping behavior is particularly common in Asian markets. In some cases, our competitors are willing to make little or no profit on a transaction, or offer travel services at a loss, in order to gain market share. As a result, in certain markets we may need to provide discounts or other incentives in order to be competitive, which may make it difficult for us to maintain or grow market share and to maintain historical profit margins. These initiatives may also result in lower ADRs and lower revenues as a percentage of gross bookings. As part of our strategy to provide more payment options to consumers and travel service providers, Booking.com is increasingly processing transactions on a merchant basis, where it facilitates payments on behalf of customers. This allows Booking.com to present consumers with more pricing options. If we are unable to effectively offer competitive prices, our market share, business and results of operations could be materially adversely affected.

Travel service providers, including hotel chains, rental car companies and airlines with which we conduct business, compete with us in online channels to drive consumers to their own platforms in lieu of third-party distributors such as us. Travel service providers may charge lower prices and, in some instances, offer advantages such as loyalty points or special discounts to members of closed-user groups (such as loyalty program participants or consumers with registered accounts), any of which could make their offerings more attractive to consumers than our services. For example, many large hotel chains have instituted additional initiatives, such as increased discounting and incentives, to encourage consumers to book accommodations directly through their online platforms. We also offer various incentives to consumers and may need to offer additional or increased advantages to maintain or grow our reservation bookings, which adversely impacts our profit margins. Further, consolidation among travel service providers, such as Marriott International's acquisition of Starwood Hotels & Resorts in 2017, could result in lower rates of commission paid to OTCs, increased discounting and greater incentives for consumers to join closed-user groups as such travel service providers expand their offerings. If we are not as effective as our competitors (including hotel chains) in offering discounted prices and other incentives to consumers, our ability to grow and compete and our results of operations could be harmed.

We derive a substantial portion of our revenues, and have significant operations, outside the United States. Our international businesses include our Netherlands-based OTC brand Booking.com (including Rentalcars.com, based in the United Kingdom), our Asia-based OTC brand agoda and, to a lesser extent, KAYAK's international meta-search services and OpenTable's international restaurant reservation services. Before the COVID-19 pandemic, our international OTC operations historically had achieved significant year-over-year growth in their gross bookings, in particular with respect to their accommodation reservation services. Without taking into consideration the recent declines caused by the COVID-19 pandemic, these growth rates, which contributed significantly to our historical growth in consolidated revenues and earnings, had generally declined over time as the absolute level of our gross bookings increased and online travel growth rates declined. In addition to the general slowing growth rates of online travel and the effects of the COVID-19 pandemic, other factors may also slow the growth rates of our international businesses, including, for example, worldwide or regional economic conditions, strengthening of the U.S. Dollar versus the Euro, the British Pound Sterling and other currencies, declines in ADRs, increases in cancellations, adverse changes in travel market conditions and the competitiveness of the market. Any decline in the growth rates of our international businesses negatively impacts our revenue and earnings growth rates and, as a consequence, our stock price.

Our long-term strategy involves continued expansion throughout the world. Many regions have different economic conditions, customs, languages, currencies, consumer expectations, levels of consumer acceptance and use of online platforms 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 make expansion in that market difficult or costly and take more time than anticipated. In addition, compliance with legal, regulatory or tax requirements in multiple jurisdictions places demands on our time and resources, and we may nonetheless experience unforeseen and potentially adverse legal, regulatory or tax consequences. In some markets such as China, legal and other regulatory requirements may prohibit or limit participation by foreign businesses, such as by making foreign ownership or management of internet or travel-related businesses illegal or difficult, or may make direct participation in those markets uneconomic, which could make our entry into and expansion in those markets difficult or impossible, require that we work with a local partner or result in higher operating costs. Certain markets in which we operate that are in earlier stages of development have lower operating margins compared to more mature markets, which could have a negative impact on our overall profit margins as these markets increase in size over time. If we are unsuccessful in expanding in new and existing markets and effectively managing that expansion, our business and results of operations could be adversely affected.

We intend to continue to improve the accommodation choices available for reservation on our platforms, however the growth rate of the number of accommodations on our platforms may vary in part as a result of removing accommodations from our platforms from time to time. We have seen a year-over-year increase in the number of accommodations removed from our platform during and resulting from the impacts of the COVID-19 pandemic, and we expect to see further accommodation removals in the future primarily due to properties not providing availability on our platforms, non-payment of invoices or property closures. Many of the newer accommodations we add to our travel reservation services, especially in highly-penetrated markets, may have fewer rooms or higher credit risk and may appeal to a smaller subset of consumers (e.g., hostels and bed and breakfasts). Because alternative accommodations are often either a single unit or a small collection of independent units, these properties generally represent more limited booking opportunities than hotels, motels and resorts, which generally have more units to rent per property. Further, alternative accommodations in general may be subject to increased seasonality due to local tourism seasons, weather or other factors or may not be available at peak times due to use by the property owners. Lower profit margins are associated with alternative accommodation properties due to certain additional costs related to offering these accommodations on our platforms. As we increase our alternative accommodation business, these different characteristics negatively impact our profit margins; and, to the extent these properties represent an increasing percentage of the properties added to our platforms, we expect that our room-night growth rate and property growth rate will continue to diverge over time (since each such alternative accommodation property has fewer booking opportunities). As a result of the foregoing, as the percentage of alternative accommodation properties increases, the number of reservations per property will likely continue to decrease.

In addition, as our alternative accommodation reservation business grows, we may incur increasing numbers of complaints related to non-existent properties or properties that are significantly different than as described in the listing, as well as claims of liability based on events occurring at such properties such as robbery, injury, death and other similar events. Such complaints or claims could result in negative publicity and increased costs, which could adversely affect our reputation, business and results of operations. Further, the regulatory environment related to some alternative accommodations such as homes and apartments is evolving, and laws, regulations or property association rules could impose restrictions or burdens on these property owners and managers 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

We believe that the number, variety and quality of accommodations on our platforms, and the corresponding access to accommodation room nights, had been a key driver of the growth of our accommodation reservation business prior to the COVID-19 pandemic. The breadth of our accommodation bookings typically made us an attractive source of consumer demand for our accommodation providers, and we believe it will continue to do so as the travel industry recovers. However, after accommodation providers recover from the COVID-19 pandemic, they may wish to limit the amount of business that flows through a single distribution channel. Also, certain jurisdictions, particularly in Europe, are considering regulations intended to address the issue of "overtourism," including by restricting accommodation offerings in city centers or near popular tourist destinations, such as by restricting construction of new hotels or the renting of homes or apartments. Such restrictions could also include limiting the number of tourists permitted to visit and stay near popular areas during peak seasons or as a general matter. As a result, we may experience constraints on the number of listings, or accommodation room nights, actually available to us, which could negatively impact our business growth rate and results of operations.

The number of our employees worldwide has grown from approximately 15,500 at December 31, 2015 to approximately 20,300 at December 31, 2020, which growth is mostly comprised of hires by our international operations. Changes in our workforce may make it more difficult to hire, train, retain, motivate and manage the required employees. Historically, our brands operated on a largely independent basis and many of them focused on particular services or geographies. As we look to develop the Connected Trip and pursue our other strategic objectives, we are increasing the collaboration, cooperation and interdependency among our brands. As we manage this shift, in addition to managing any changes in our workforce, whether due to organic growth, growth through acquisitions, workforce reductions or restructurings, we may find it difficult to maintain the beneficial aspects of our corporate culture at the brand companies and throughout the organization as a whole. In addition, as travel recovers from the COVID-19 pandemic, any future expansion or shift increases the complexity of our business and places additional strain on our management, operations, technical performance, financial resources and administrative, legal, tax, internal control and financial reporting functions. Our current and planned employees, systems, procedures and controls may not be adequate to support and effectively manage growth and increased complexity, especially as we employ employees in multiple geographic locations around the world and increase the number and variety of our products and payment systems. The implementation of new information technology, payment, enterprise resource planning (ERP) or other systems could be disruptive and/or costly or we may experience difficulty successfully integrating new systems into existing systems or migrating to new systems from existing systems, any of which could adversely affect our business and results of operations.

We believe that maintaining and strengthening our brands are important aspects of our efforts to attract and retain customers. We have invested considerable resources in the establishment and maintenance of our brands, and we intend to continue to invest resources in marketing and other brand building efforts to preserve and enhance consumer awareness of our brands when and to the extent we deem appropriate, in particular as the COVID-19 pandemic subsides and consumers begin to travel again. Effective marketing has been an important factor in our growth, and we believe it will continue to be important to our future success. Our marketing spend is influenced by the marketing spend of our competitors as we seek to maintain and increase our brand recognition among consumers and to maintain and grow traffic to our platforms through performance marketing channels. We may not be able to successfully maintain or enhance consumer awareness and acceptance of our brands, and, even if we are successful in our branding efforts, such efforts may not be cost-effective. For instance, increased marketing by OTCs, meta-search services and travel service providers, which we saw prior to the COVID-19 pandemic and would expect to see again as the COVID-19 pandemic subsides, make our marketing efforts more expensive and less effective. If we are unable to maintain or enhance consumer awareness and acceptance of our brands in a cost-effective manner, our business, market share and results of operations would be materially adversely affected.

Our marketing efficiency, expressed as marketing expense as a percentage of revenues, is impacted by a number of factors that are subject to variability and that are, in some cases, outside of our control, including ADRs, costs per click, cancellation rates, foreign currency 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. For example, competition for desired rankings in search results and/or a decline in ad clicks by consumers could increase our costs-per-click and reduce our marketing efficiency. We use third-party websites, including online search engines (primarily Google), meta-search and travel research services and

We believe that a number of factors could cause consumers to increase their shopping activity before making a travel purchase. Increased shopping activity reduces our marketing efficiency and effectiveness because traffic becomes less likely to result in a reservation through our platforms, and such traffic is more likely to be obtained through paid marketing channels than through direct channels. Further, consumers may favor travel services offered by search or meta-search companies over OTCs, which could reduce traffic to our travel reservation platforms, increase consumer awareness of our competitors' brands and platforms, increase our marketing and other customer acquisition costs and adversely affect our business, margins and results of operations. To the extent any such increased shopping behavior leads to growth in our KAYAK meta-search business, such growth may not result in sufficient increases in revenues from our KAYAK meta-search business to offset any related decrease in revenues or increase in marketing and other customer acquisition costs experienced by our OTC brands.

The markets in which we compete are characterized by rapidly changing technology, evolving industry standards, consolidation, frequent new service announcements, introductions and enhancements and changing consumer demands and preferences. These characteristics are changing at an even greater pace as OTCs and travel service providers seek to address consumer needs and preferences resulting from the COVID-19 pandemic. We may not be able to keep up with these rapid changes. In addition, these market characteristics are heightened by the progress of technology adoption in various markets, including the continuing adoption of the internet and online commerce in certain geographies and the emergence and growth of the use of smartphones, tablets and other smart devices, including those with voice and artificial intelligence capabilities, for mobile e-commerce transactions. New developments in other areas, such as cloud computing, could make entering our markets easier for competitors due to lower upfront technology costs. As a result, our future success will depend on our ability to adapt to rapidly changing technologies, to adapt our services and online platforms to evolving industry standards and local preferences and to continually innovate and improve the performance, features and reliability of our services and online platforms in response to competitive service offerings and the evolving demands of the marketplace. In particular, it is increasingly important for us to effectively offer our services on mobile devices through mobile apps and mobile-optimized websites and to tailor our services to varying devices and platforms. Any failure by us to successfully develop and achieve consumer adoption of our mobile platforms would have a material and adverse effect on our growth, market share, business and results of operations. Further, to the extent mobile devices or platforms enable users to block advertising content, our advertising revenue and our ability to market our brands and acquire new consumers may be negatively affected. We believe that ease-of-use, comprehensive functionality and the look and feel of our mobile platforms are increasingly competitively critical as consumers obtain more of their travel and restaurant services through mobile devices and platforms. As a result, we intend to continue to spend significant resources maintaining, developing and enhancing our mobile platforms and other technologies and platforms in the long term. Additionally, our ability to achieve our long-term strategy to build the Connected Trip depends on successfully integrating and developing new and evolving technologies, which is likely to require increased financial and personnel investments that could have an adverse impact on our results of operations until we achieve the expected return on these investments. However, these efforts may not be successful in improving the travel experience or retaining and attracting new customers, which would harm our business and results of operations. Further, technical innovation often results in bugs, vulnerabilities and other system failures. Any such bug, vulnerability or failure, especially in connection

We believe that another critical component to our future success will be our ability to enhance our payments capabilities, including by offering alternative payment solutions to consumers even when those payment solutions may not be accepted by the travel service provider or restaurant. Alternate payment providers such as Alipay, Paytm and WeChat Pay operate closed-loop payments systems with direct connections to both consumers and merchants. In many markets, particularly in Asia where credit cards are not readily available and/or e-commerce is largely carried out through mobile devices, these and other emerging alternative payment methods are the exclusive or preferred means of payment for many consumers. Therefore, if we are unable to offer consumers their preferred method of payment by integrating new or emerging payment methods into our platforms, we may not be able to effectively offer our services to these consumers, which would limit our growth opportunities in these markets and our business and results of operations could be harmed.

Furthermore, in the future the competitive pressure to innovate could encompass a wider range of services and technologies, including services and technologies that may be outside of our historical core business, and our ability to keep pace may slow. Our current and potential competitors range from large and established companies to emerging start-ups. Emerging start-ups may be able to innovate and focus on developing a particularly new product or service faster than we can or may foresee consumer need for new services or technologies before we do. Some of our larger competitors or potential competitors have more resources or more established or varied relationships with consumers than we have, and they could use these advantages in ways that could affect our competitive position, including by making acquisitions, entering or investing in travel reservation businesses, investing in research and development and competing aggressively for highly-skilled employees.

In addition, the widespread adoption of new internet, networking or telecommunications technologies or other technological changes (including new devices and services, such as Amazon's Echo and Alexa and Google Home and Google Assistant, developing technologies, such as artificial intelligence, chatbot and virtual reality technologies, and the creation of "super-apps" where consumers can use many online services without leaving a particular app) could require us to incur substantial expenditures to modify or adapt our services or infrastructure to these new technologies, which could adversely affect our results of operations or financial condition. Any failure to implement or adapt to new technologies in a timely manner or at all could adversely affect our ability to compete, increase our consumer acquisition costs or otherwise adversely affect our business, and therefore adversely affect our brand, market share and results of operations.

We use Google to generate a significant portion of the traffic to our platforms, and, to a lesser extent, we use other search and meta-search services to generate traffic to our platforms, principally through pay-per-click marketing campaigns. The pricing and operating dynamics on these search and meta-search platforms can experience rapid change commercially, technically and competitively. For example, Google frequently updates and changes the logic which determines the placement and display of results of a consumer's search, such that the placement of links to our platforms can be negatively affected and our costs to improve or maintain our placement in search results can increase. The European Commission has fined Google significant amounts for anti-competitive behavior relating to its comparison-shopping service and online search advertising services. Changes by Google in how it presents travel search results, including its promotion of its travel meta-search services, or the manner in which it conducts the auction for placement among search results, whether as a result of a court order, investigation or other reason, may be competitively disadvantageous to us and may impact our ability to efficiently generate traffic to our platforms, which in turn would have an adverse effect on our business, market share and results of operations. In January 2020, Google announced modifications to its flights display model, including that it would not be charging airlines and OTCs for sending referrals from Google Flights. As a result, certain airline and OTC partners have limited or eliminated their use of other meta-search services and have demanded cost savings from their other meta-search services. Further, Google may receive access to certain discounted fares not provided to meta-search services that charge for referrals. These modifications could adversely affect our meta-search business, profit margins and results of operations. Similarly, changes by our other search and meta-search partners in how they present travel search results or the manner in which they conduct the auction for placement among search results may be competitively disadvantageous to us and may impact our ability to efficiently generate traffic to our platforms. In addition, a decline or slowing growth in travel search traffic negatively impacts our ability to efficiently generate traffic to our platforms through performance marketing on general search platforms, which could have an adverse effect on our business and results of operations.

In addition, we purchase online traffic from a number of other sources, including some operated by our competitors, in the form of pay-per-click arrangements that can be terminated with little or no notice. If one or more of such arrangements is terminated, our business, market share and results of operations could be adversely affected. We rely on various third-party

Widespread adoption of mobile devices, such as the iPhone and Android-enabled smartphones, coupled with the web browsing functionality and development of thousands of apps available on these devices, continues to drive substantial online traffic and commerce to mobile platforms. We have experienced a significant shift of business, both direct and indirect, to mobile platforms and our advertising partners are also seeing a rapid shift of traffic to mobile platforms. Some competitors offer last-minute discounts for mobile accommodation reservations. The revenues earned on a mobile transaction may be less than a typical desktop transaction due to different consumer purchasing patterns. For example, accommodation reservations made on a mobile device typically are for shorter lengths of stay, have lower ADRs and are not made as far in advance. Further, given the device sizes and technical limitations of smartphones, mobile consumers may not be willing to download multiple apps from multiple companies providing a similar service and instead prefer to use one or a limited number of apps for their mobile travel and restaurant research and reservation activity. As a result, the consumer experience with mobile apps as well as brand recognition and loyalty continue to be 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 to mobile devices instead of a personal computer. As a result, it is increasingly important for us to develop and maintain effective mobile platforms to provide consumers with an appealing, easy-to-use mobile experience. If we are unable to continue to rapidly innovate and create new, user-friendly and differentiated mobile offerings and efficiently and effectively advertise and distribute on these platforms, or if our mobile offerings are not used by consumers, we could lose market share and our business, future growth and results of operations could be adversely affected.

Google's Android operating system is the leading smartphone operating system in the world. As a result, Google has the ability to leverage its Android operating system to give its travel services a competitive advantage, either technically or with prominence on its Google Play app store or within its mobile search results. Further, Google is the leading internet search service and has leveraged its search popularity to promote its travel services. The European Commission has fined Google significant amounts and the U.S. Justice Department (the "U.S. DOJ") has sued Google for breaching antitrust rules by imposing restrictions on Android device manufacturers and mobile network operators, including by mandating the pre-installation of Google apps and limiting access to its Google Play app store. The European Commission's decision requires Google to end those practices or face penalty payments of up to 5% of the average daily worldwide turnover of Alphabet, Google's parent company. Google has appealed the European Commission's decision and refutes the U.S. DOJ's claims, and it is not yet clear how or whether these actions will affect Google's business, including its travel services.

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 check in for a travel reservation. In addition, Apple's iPhone operating system includes "Wallet," a virtual wallet app that holds tickets, boarding passes, coupons and gift cards, and, along with iTravel, may be indicative of Apple's intent to enter the travel reservations business in some capacity. Apple has substantial market share in the smartphone market and controls integration of offerings, including travel services, into its mobile operating system. Apple also has more experience producing and developing mobile apps and has access to greater resources than we have. Apple may use or expand iTravel, Wallet, Siri (Apple's voice recognition "concierge" service), Apple Pay (Apple's mobile payment system) or another mobile app or functionality as a means of entering the online travel reservations marketplace. To the extent Google or Apple use their mobile operating systems, app distribution channels 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 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, rental cars or airline tickets, or to make accommodation reservations, rental cars or airline tickets available in any geographic area, for any particular route or at any particular price. Similarly, our arrangements with restaurants generally do not require them to provide all of their available tables and reservations to customers through us. We are in regular dialogue with our major travel service providers about the nature and extent of their participation in our services. A significant reduction on the part of any of our major travel service providers or providers that are particularly popular with consumers in their participation in our services for a sustained period of time or

KAYAK, a meta-search service, depends on access to information related to travel service pricing, schedules, availability and other related information from OTCs and travel service providers to attract consumers. Many of KAYAK's agreements with OTCs and travel service providers 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 travel service information to consumers could be diminished and its brand, business and results of operations could be harmed. To the extent consumers do not view KAYAK as a reliable source of comprehensive travel service information, fewer consumers would likely visit its websites, which would also likely have a negative impact on KAYAK's advertising revenue and results of operations. In addition, if OTCs or travel service providers choose not to advertise with KAYAK or choose to reduce or eliminate the fees paid to KAYAK for referrals from query results, KAYAK's business and results of operations could be adversely affected.

Our performance is largely dependent on the talents and efforts of highly skilled individuals. Our future success depends on our continuing ability to identify, hire, develop, motivate and retain highly skilled employees for all areas of our organization. In particular, the contributions of key senior management 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 any members of our senior management or other key employees, the loss of whom could harm our business and competitive position. We do not maintain any key person life insurance policies.

In addition, competition for well-qualified employees in all aspects of our business, including software engineers, mobile communication talent and other technology professionals, is intense. Our international success in particular has led to increased efforts by our competitors and others to hire our international employees. These difficulties may be amplified by evolving restrictions on immigration, travel or availability of visas or work permits for skilled technology workers. Further, as a result of the COVID-19 pandemic, the potential for a long recovery period for the travel industry and our workforce reductions and restructurings, employees may not view employment with us as positively as they did prior to the pandemic, all of which makes attraction and retention of well-qualified employees more difficult. The competition for talent in our industry has in the past and may in the future increase our personnel expenses, which may adversely affect our results of operations. Our continued ability to compete effectively and to innovate and develop products, services, technologies and enhancements depends on our ability to attract, retain and motivate well-qualified employees. If we do not succeed in attracting well-qualified employees or retaining, training, managing and motivating existing employees, our business, competitive position, reputation and results of operations would be adversely affected.

Our mission is to make it easier for everyone to experience the world. As a result, our strategy involves evaluating and potentially entering complementary businesses in furtherance of that mission. We have invested, and in the future may invest, in new business strategies and acquisitions. For example, we acquired FareHarbor in April 2018 to increase our ability to offer local activities and experiences (such as tours and attractions). We also have acquired, and in the future may acquire,

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 have business 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 our reputation or business or adversely affect the value of our investment. A substantial portion of our goodwill and intangible assets were acquired in acquisitions. If we determine that any of our 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, as we did in the first and third quarters of 2020, an impairment (see Note 11 to our Consolidated Financial Statements), which could materially adversely affect our results of operations. Further, we may issue shares of our common stock in these transactions, which could result in dilution to our stockholders.

The integration of acquired businesses requires significant time and resources, and we may not manage these processes successfully. Further, as our businesses developed, our strategy evolved and market conditions changed, we have integrated businesses that had been managed independently, integrated certain functions across businesses and restructured or ceased operating certain assets or businesses, and we may do so in the future, including through divestitures. These integrations may be of varying degree, depending on many factors such as business compatibility, strategic goals or geographic location, among others. Integrations are complex, often involve additional or unexpected costs and create a variety of issues and risks, including:

We may not successfully integrate companies or achieve the strategic, financial or operating objectives of the acquisition or integration, any of which could adversely affect our business, results of operations or the value of our acquisitions.

party systems could significantly harm our reputation and therefore our business, brand, market share and results of operations. Consumers who use certain of our services provide us with their credit card information. We require user names and passwords in order to access our information technology systems. We also use encryption and authentication technologies to secure the transmission and storage of data and prevent unauthorized access to our data or accounts. Computer circumvention capabilities, new discoveries or advances or other developments, including our own acts or omissions, could result in a compromise or breach of consumer data. For example, third parties may attempt to fraudulently induce employees, travel service provider partners or consumers 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 partners or consumers. Third parties may also attempt to take over consumer accounts by using passwords, usernames and other personal information obtained elsewhere to attempt to unlawfully access consumer accounts on our platforms. We have experienced targeted and organized phishing and account takeover attacks, which have increased during the COVID-19 pandemic, and we expect to continue to experience these events in the future. These risks are likely to increase as we expand our offerings, integrate our products and services, and store and process more data, including personal information. Our efforts to protect information from unauthorized access may be unsuccessful or may result in the rejection of legitimate attempts to book reservations through our services, any of which could result in lost business and could materially and adversely affect our business, reputation and results of operations.

Our existing technical, administrative and physical security measures may not be successful in preventing security breaches. A party (whether internal, external, an affiliate or unrelated third party) that is able to circumvent our security systems could steal consumer information or transaction data or other proprietary information. As a result of increased numbers of employee exits due to the restructuring actions or otherwise, we face heightened risks related to the loss or unauthorized use of or access to our systems, intellectual property or other protected data. In the last few years, several major companies experienced high-profile security breaches that exposed their systems and information and/or their consumers' or employees' personal information, and it is expected that these types of events will continue to occur. We have a heightened risk of security breaches due to some of our operations being located in certain international jurisdictions. We expend significant resources to protect against security breaches, and regularly increase our security-related expenditures to maintain or increase our systems' security. We have experienced and responded to cyberattacks, which we believe have not had a significant impact on the integrity of our systems or the security of data, including personal information maintained by us. These issues are likely to become more difficult to manage as we expand the number of places where we operate and the number and variety of services we offer, and as the tools and techniques used in such attacks increasingly become more sophisticated. Security breaches could result in severe damage to our information technology infrastructure, including damage that could impair our ability to offer our services or the ability of consumers to make reservations or conduct searches through our services, as well as loss of consumer, financial or other data that could materially and adversely affect our ability to conduct our business, satisfy our commercial obligations or meet our public reporting requirements in a timely fashion or at all. Security breaches could also result in negative publicity, damage our reputation, expose us to risk of loss or litigation and possible liability, subject us to regulatory penalties and sanctions, or cause 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 our brands, market share, results of operations and financial condition. Our insurance policies have coverage limits and may not be adequate to reimburse us for all losses caused by security breaches.

We also face risks associated with security breaches affecting third parties conducting business over the internet. Consumers generally are concerned with security and privacy on the internet, and any publicized security problems could negatively affect consumers' willingness to provide private information or effect online commercial transactions generally, including through our services. Some of our business is conducted with third-party marketing affiliates, which may generate travel reservations through our infrastructure or through other systems. Additionally, our consumers' personal data could be affected by security breaches at third parties upon which we rely, such as travel service providers, connectivity partners, payroll providers, health plan providers, payment processors or GDSs. A security breach at any such third-party marketing affiliate, travel service provider, payment processor, GDS or other third party on which we rely, such as the security breach experienced by MGM Resorts International in 2020, could be perceived by consumers as a security breach of our systems and in any event could result in negative publicity, subject us to notification requirements, damage our reputation, expose us to risk of loss or litigation and possible liability and subject us to regulatory penalties and sanctions. In addition, such third parties may not comply with applicable disclosure requirements or with parameters within which we permit them to process data, which could expose us to liability.

In the operation of our business, we receive and store a large volume of personally identifiable data and payment information. This data is increasingly subject to legislation and regulations in numerous jurisdictions around the world. The European Union's General Data Protection Regulation (the "GDPR") imposes significant compliance obligations and costs for us. Under the GDPR, violations could result in fines of up to 20 million Euros or up to 4% of the annual global revenues of the infringer, whichever is greater. Several data protection authorities have imposed significant fines on companies of various sizes across industry sectors for violations of the GDPR. The California Consumer Privacy Act (the "CCPA") became operative in

Prior to the COVID-19 pandemic, we experienced rapid growth in consumer traffic to our online platforms, the number of accommodations on our extranets and the geographic breadth of our operations. Once consumers begin to travel again, if our systems cannot be expanded to cope with increased demand or fail to perform, we could experience unanticipated disruptions in service, slower response times, decreased customer service and customer satisfaction and delays in the introduction of new services, any of which could impair our reputation, damage our brands and materially and adversely affect our results of operations. Further, as an online business, we are dependent on the internet and maintaining connectivity between ourselves and consumers, sources of internet traffic, such as Google, and our travel service providers and restaurants. As consumers increasingly turn to mobile and other smart devices, we also become dependent on consumers' access to the internet through mobile carriers and their systems. Disruptions in internet access, whether generally, in a specific market or otherwise, especially if widespread or prolonged, could materially adversely affect our business and results of operations. While we do maintain redundant systems and hosting services, it is possible that we could experience an 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 are vulnerable to damage or interruption from human error, computer viruses, floods, fires, power loss, telecommunication failures and similar events. They are also subject to break-ins, sabotage, intentional acts of vandalism, terrorism and similar misconduct. Despite any precautions we may take, the occurrence of any disruption of service due to any such misconduct, natural disaster or other unanticipated problems at such facilities, or the failure by such facilities to provide our required data communications capacity could result in lengthy interruptions or delays in our services. Any system failure that causes an interruption or delay in service could impair our reputation, damage our brands, result in lost business 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 interruptions in our operations. For instance, from time to time, we have experienced denial-of-service type attacks on our systems that have made portions of our websites slow or unavailable for periods of time. There are numerous other potential forms of attack, such as phishing, ransomware, account takeover attacks, SQL injection (where a third party attempts to insert 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 a platform to launch a denial-of-service attack on another party, each of which could cause significant interruptions in our operations and potentially adversely affect the value of our brands, operations and results of operations or involve us in legal or regulatory proceedings. We expend significant resources in an attempt to prepare for and mitigate the effects of any such attacks. Reductions in the availability and response time of our online services could cause loss of substantial business 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 attack could result in the diversion of bona fide customers. These issues are more difficult to manage during any expansion of the number of places where we operate and the variety of services we offer, and as the tools and techniques used in such attacks become more advanced. Successful attacks could result in negative publicity, damage our reputation 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 of the accommodation, rental car and airline industries in connection with providing some of our services. Any damage to, breach of or interruption in these third-party services and systems or deterioration in their performance could prevent us from booking related accommodation, rental car and airline reservations and have a material adverse effect on our business, brands and results of operations. Our agreements with some third-party service providers are terminable upon short notice and often 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 an alternative 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 our business and results of operations. Further, as a result of the COVID-19 pandemic, some of our third-party service providers may go out of business, suspend operations, reduce their support services or system maintenance activities, any of which could adversely affect our business and reputation.

We depend upon various third parties to process payments, including credit cards, for our merchant transactions around the world. In addition, we rely 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 or partially compromised or ceased or suspended operations (whether due to the COVID-19 pandemic or otherwise), our cash flows could be disrupted or we may not be able to generate merchant transactions (and related revenues) until such a time as a replacement process could be put in place with a different vendor, and this could have a negative effect on our business, reputation and results of operations and, in certain cases of the insolvency of such a partner, could result in additional payments by us and loss of the total transaction value, which would negatively affect our results of operations and financial condition.

We do not have a completely formalized or comprehensive disaster recovery plan in every geographic region in which we conduct business. In the event 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 many online businesses, we have experienced system failures from time to time. In addition to placing increased burdens on our engineering staff, these outages create a significant amount of consumer questions and complaints that need to be addressed by our customer support employees. Any unscheduled interruption in our service could result in an immediate loss of revenues that could be substantial, increase customer service costs, harm our reputation and result in some consumers switching to our competitors. If we experience frequent or persistent system failures, our reputation and brand could be permanently and significantly harmed. We have taken and continue to take steps to increase the reliability and redundancy of our systems. These steps are expensive, may reduce 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 and financial and accounting systems. If the number of consumers using our services increases substantially, or if critical third-party systems stop operating as designed, we may need to significantly expand and upgrade our technology, transaction processing systems, financial and accounting systems or other infrastructure. We may not be able to upgrade our systems and infrastructure to accommodate such conditions in a timely manner, and, depending on the systems affected, our transactional, financial and accounting systems could be impacted for a meaningful amount of time before upgrade, expansion or repair. Many of our processes and systems, including those related to processing and recording revenue, are highly automated and involve multiple inputs from various IT systems, which can mitigate the risk of human error but which can also make testing, troubleshooting and auditing more difficult. As a result, it may be difficult to quickly detect and correct errors embedded in these processes or systems.

As an international business providing reservation and marketing services around the world, we are subject to income taxes and non-income-based taxes in the United States and various international jurisdictions. Due to economic and political conditions, tax rates and tax regimes in various jurisdictions may be subject to significant change. Our future effective tax rates 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 in tax laws or their interpretation. If our effective tax rates were to increase, our results of operations and cash flows would be adversely affected.

Although we believe that our tax filing positions are reasonable and comply with applicable law, we regularly review our tax filing positions, especially in light of tax law or business practice changes, and we may change our positions or determine that previous positions should be amended, either of which could result in additional tax liabilities. The final determination of tax audits or tax disputes may be different from what is reflected in our historical income tax provisions and

In general, governments are increasingly focused on ways to increase tax revenues, which has contributed to an increase in audit activity, more aggressive positions taken by tax authorities, more time and difficulty to resolve any audits or disputes and an increase in new tax legislation. Any such additional taxes or other assessments may be in excess of our 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 which could have a material adverse effect on our business, results of operations and financial condition.

In December 2017, the Tax Cuts and Jobs Act (the "Tax Act") was enacted into law in the United States. The Tax Act introduced a tax on 50% of global intangible low-taxed income ("GILTI"), which is income determined to be in excess of a specified routine rate of return on qualifying business assets. The Tax Act further introduced a base erosion and anti-abuse tax ("BEAT") aimed at preventing the erosion of the U.S. tax base and a new tax deduction with respect to certain foreign-derived intangible income. If we are unable to operate our business so that BEAT does not impact us, our effective tax rate, results of operations and cash flows would be adversely affected. The interpretation and implementation of the Tax Act and regulations, rules or guidance that have been or may be adopted under, or result from, the Tax Act have had and could have a negative impact on our results of operations and cash flows. During the 2020 U.S. presidential campaign, then presidential candidate Joseph Biden proposed making significant corporate income tax changes including raising the U.S. corporate income tax rate to 28% and increasing the percentage of GILTI subject to tax in the United States to 75%. Increases in the U.S. corporate income tax rate or increasing the percentage of GILTI subject to tax in the United States could have a negative impact on our results of operations and cash flows.

Additionally, there have been significant changes made and proposed to international tax laws that increase the complexity, burden and cost of tax compliance. The Organisation for Economic Co-operation and Development ("OECD") initiated the "base erosion and profit shifting" ("BEPS") project to ensure international tax standards keep pace with changes in global business practices and to address situations where multinational businesses may pay little or no tax in certain jurisdictions by shifting profits away from jurisdictions in which the profit generating activities take place. The OECD is working towards a consensus-based solution by the middle of 2021 to address the challenges posed to the current tax system by the digitalization of the economy. The OECD Secretariat's current proposal aims to ensure that multinational businesses are taxed in jurisdictions where they are conducting significant business but do not have a physical presence by establishing new nexus rules determining where tax should be paid and new profit allocation rules determining what portion of profits should be taxed.

Certain countries have taken steps to unilaterally introduce a digital services tax to address the issue of multinational businesses carrying on business in their jurisdiction without a physical presence and therefore generally not subject to income tax in those jurisdictions. These digital services taxes are calculated as a percentage of revenue rather than income or profits. As a result, with the exception of the U.K digital services tax, these taxes apply even in situations where the business may be operating at an overall loss. In most cases, since these digital services taxes are based on revenue and not income, they cannot be credited against taxes paid on income in another jurisdiction for the same revenue. The interpretation and implementation of the various digital services taxes (especially if there is inconsistency in the application of these taxes across tax jurisdictions) could have a materially adverse impact on our results of operations and cash flows. Further, digital services taxes may not apply to our competitors such as hotel chains and smaller OTCs, which harms our business and competitive position. Any changes to international tax laws, including new definitions of permanent establishment, new nexus and profit allocation rules, or changes affecting the benefits of preferential tax regimes such as the Dutch "Innovation Box Tax" (discussed below), could impact the tax treatment of our foreign earnings and adversely impact our effective tax rate. Further, changes to tax laws and additional reporting requirements could increase the complexity, burden and cost of compliance. Due to the large scale of our international business activities, any changes in U.S. or international taxation of our activities or the combined effect of tax laws in multiple jurisdictions may increase our worldwide effective tax rate, increase the complexity and costs associated with tax compliance (especially if changes are implemented or interpreted inconsistently across tax jurisdictions) and adversely affect our cash flows and results of operations.

We are also subject to other non-income-based taxes, such as value-added, payroll, sales, use, excise, net worth, property, hotel occupancy and goods and services taxes. We refer generally to taxes on travel transactions (e.g., value-added taxes, sales taxes, excise taxes, hotel occupancy taxes, etc.) as "travel transaction taxes." From time to time, we are under audit or investigation by tax authorities or involved in legal proceedings related to these non-income-based taxes or we may revise or amend our tax positions, which may result in additional non-income-based tax liabilities. A number of jurisdictions in the United States have initiated lawsuits against OTCs, including us, related to, among other things, the payment of certain travel transaction taxes (such as hotel occupancy taxes) that could include historical taxes that are claimed to be owed, interest, penalties, punitive damages and/or attorney's fees and costs. In addition, a number of jurisdictions have initiated audit proceedings, issued proposed tax assessments or started inquiries relating to the payment of travel transaction taxes. Additional jurisdictions may assert that we are subject to, among other things, travel transaction taxes and could seek to collect such taxes, either retroactively, prospectively or both. Jurisdictions could also seek to amend their tax statutes in order to collect travel transaction taxes from us on a prospective basis. Litigation is subject to uncertainty and there could be adverse developments in these pending or future cases and proceedings. Additionally, a number of jurisdictions have adopted or may adopt laws that require us to collect and remit sales tax on behalf of travel service providers, which in some instances may negatively impact our revenue. Adverse tax decisions or new laws could have a material adverse effect on our business, margins, cash flows and results of operations. An unfavorable outcome or settlement of pending litigation may encourage the commencement of additional litigation, audit proceedings or other regulatory inquiries. In addition, an unfavorable outcome or settlement 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.

The Netherlands corporate income tax law provides that income generated from qualifying innovative activities is taxed at the rate of 7% prior to 2021 and 9% beginning in January 2021 ("Innovation Box Tax") rather than the Dutch statutory rate of 25%. A portion of Booking.com's earnings historically has qualified for Innovation Box Tax treatment. In 2020, the Innovation Box Tax benefit reduced our consolidated income tax expense by $79 million.

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 the subsequent 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 determine that the activities 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 for continued Innovation Box Tax treatment for future periods. However, Booking.com's application may not be accepted, or, if accepted, the amount of qualifying earnings may be reduced.

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 Dutch government that Booking.com's activities are not innovative or for any other reason, could substantially increase our effective tax rate and adversely impact our results of operations and cash flows in the future.

We, the travel industry and the technology industry generally are subject to competition/anti-trust and consumer protection laws and regulations around the world. These laws and regulations evolve and change, and their interpretation, application and enforcement can also change, be unpredictable or be affected by changing political or social pressures. As we expand our business into new areas, including our evolution towards the Connected Trip, we may become subject to additional laws and regulations. At times, online travel platforms, including us, have been the subject of investigations or inquiries by various national competition authorities ("NCAs") or other governmental authorities. For example, we have been and continue to be involved in investigations related to whether Booking.com's contractual parity arrangements with accommodation providers, sometimes also referred to as "most favored nation" or "MFN" provisions, are anti-competitive because they require accommodation providers to provide Booking.com with room rates, conditions or availability that are at least as favorable as those offered to other OTCs or through the accommodation provider's website. To resolve and close certain of the investigations, we have from time to time made commitments to the investigating authorities regarding future business practices or activities. For example, Booking.com has made commitments to several NCAs, including agreeing to narrow the scope of its parity arrangements, in order to resolve parity-related investigations. In August 2020, Booking.com voluntarily extended its

We have also been involved in investigations or inquiries involving consumer protection matters. For example, the United Kingdom's NCA (the Competition and Markets Authority, or CMA) launched a consumer protection law investigation into the clarity, accuracy and presentation of information on hotel booking sites. In connection with this investigation, in 2019, Booking.com, agoda and KAYAK, along with a number of other OTCs, voluntarily agreed to certain commitments with the CMA, which resolved the CMA's investigation without a finding by the CMA of an infringement or an admission of wrongdoing by the OTCs involved. Among other things, the commitments provided to the CMA include showing prices inclusive of all mandatory taxes and charges, providing information about the effect of money earned on search result rankings on or before the search results page and making certain adjustments to how discounts and statements concerning popularity or availability are shown to consumers. The CMA has stated that it expects all market participants to adhere to the same standards, regardless of whether they formally signed the commitments. As a result of additional inquiries from other NCAs in the European Union, Booking.com has made similar commitments with the Consumer Protection Cooperation Network that became applicable in the European Union in June 2020. There are consumer protection investigations or inquiries in other countries as well, including in Brazil, and other countries may decide to investigate these or similar issues generally or with respect to specific businesses, including ours, and we are unable to predict the outcome of any such other investigations or inquiries. To the extent that any such other investigations or inquiries result in additional commitments, fines, damages or other remedies, our business, financial condition and results of operations could be harmed.

As markets evolve and NCAs or other governmental authorities continue to monitor our industry, new investigations of the industry generally or of us specifically could and have occurred, including revisiting issues that were the subject of prior investigations. For example, in July 2020, the European Commission announced that it will study the marketing and sale of hotel accommodations in six E.U. countries in 2021. Also, while we believe that we are complying with our commitments, investigating authorities or third parties may determine that we are not complying with the commitments we have made and decide to pursue legal action to compel compliance or seek other remedies. Further, in September 2017 the Swiss Price Surveillance Office opened an investigation into the level of commissions of Booking.com in Switzerland and the investigation is ongoing. If there is an adverse outcome and Booking.com is unsuccessful in any appeal, Booking.com could be required to reduce its commissions in Switzerland.

We are cooperating with regulators where applicable, but we are unable to predict what, if any, effect any investigations or resolutions thereof, including the effect of any commitments we might make, 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 the industry, our business, competitive position and results of operations could be materially and adversely affected. Negative publicity regarding competition and/or consumer law investigations could adversely affect our brands and therefore our business, market share and results of operations. Competition and consumer law-related investigations, legislation or issues have and could in the future result in private litigation.

Another area of regulatory inquiry involves contractual search term bidding restrictions where one contracting party agrees not to bid on certain key search terms related to the other party (e.g., such other party’s name). Although we are generally moving away from these types of agreements, in some of our contracts, we or the other party have agreed to bidding restrictions. If bidding restrictions are held to be illegal or otherwise unenforceable or if we remove them from all of our contracts, our performance marketing costs may increase if bidding on affected key words (especially those related to us) becomes more expensive, which could adversely affect our performance marketing efficiency, business and results of operations.

There is significant legislative and public focus on the technology industry, especially as technology companies become larger. In some instances, countries have passed legislation that goes further to restrict business activities than actions taken by NCAs or other regulatory authorities. For example, France, Italy, Belgium and Austria have passed legislation prohibiting parity contract clauses in their entirety. Additionally, the EU's Platform to Business Regulation regulates the relationship between online platforms such as Booking.com and European business users of online platforms. This new regulation requires online platforms to provide additional disclosure to European business partners, such as terms related to

With additional attention on the size of travel or technology companies generally, our size and market share may negatively affect our ability to obtain regulatory approval of proposed acquisitions, our ability to expand into complementary businesses or our latitude in dealing with travel service providers (such as by limiting our ability to provide discounts, rebates or incentives or to exercise contractual rights), any of which could adversely affect our business, results of operations or ability to grow and compete.

Our ability to provide our services and any future services is and will continue to be affected by legal regulations (including laws, ordinances, rules, licensing requirements and other requirements and regulations) of national and local governments and regulatory authorities around the world, many of which are evolving and subject to the possibility of new or revised interpretations. For example, we offer optional rental car-related insurance products to customers protecting them against accidental damage to their rental vehicles, which subjects us to certain insurance regulations and related increased compliance costs and complexities, any of which could negatively impact our business and results of operations. Laws in some countries relating to data localization, registration as a travel agent and other local requirements could, if applicable to us, adversely affect our ability to conduct business in those countries. Any increase in the number or complexity of the laws and regulations applicable to us and our businesses could increase our compliance costs and burdens and negatively affect our business and results of operations.

For example, in the European Union, the Package Travel Directive (the "Package Directive") sets out broad requirements such as local registration, certain mandatory financial guarantees, disclosure requirements and other rules regulating the provision of travel packages and linked travel arrangements. The Package Directive also creates additional liability for a provider of travel packages, which could be the OTC, for performance of the travel services within a packaged trip under certain circumstances. Some parts of our business are already subject to the broad scope of the Package Directive, and as our offerings continue to diversify and expand, we may become subject to additional requirements of the Package Directive. Compliance with this directive could be costly and complex or, as a result of these requirements, we could choose to limit offerings that would otherwise be beneficial for the business, any of which could adversely affect our business, results of operations or ability to grow and compete.

The implementation of unfavorable regulations or unfavorable interpretations of existing regulations by judicial or regulatory bodies could require us to incur significant compliance costs, cause the development of the affected markets to become impractical and otherwise have a material adverse effect on our business and results of operations. For example, in connection with a lawsuit begun in 2015 by the Association of Turkish Travel Agencies, a Turkish court ordered in 2019 that Booking.com must meet certain registration requirements in order to offer Turkish hotels and accommodations to Turkish residents. If Booking.com does not successfully appeal this decision or meet the Turkish registration requirements, Booking.com will be unable to resume offering Turkish hotels and accommodations to Turkish residents, which would continue to negatively impact our results of operations. Another example is that the U.S. Government announced in May 2019 that it will no longer suspend the right of private parties to bring litigation under Title III of the Cuban Liberty and Solidarity (Libertad) Act of 1996, popularly known as the Helms-Burton Act, allowing certain individuals whose property was confiscated by the Cuban government beginning in 1959 to sue anyone who "traffics" in the property in question in U.S. courts. We are a defendant in a number of these lawsuits, which seek remedies including the value of the expropriated property (generally, the applicable hotel), plus interest, treble damages, attorneys' fees and costs. We believe that we have meritorious defenses to existing and potential claims and that the results of any related litigation will not be material to our business, financial condition or results of operations. However, litigation is uncertain and there is little judicial history or interpretation of the relevant

Certain jurisdictions, particularly in Europe, are considering regulations intended to address the issue of "overtourism," including restrictions that may adversely affect our ability to offer accommodations, in particular, alternative accommodations, near city centers or popular tourist destinations. To the extent any such regulations require online platforms such as ours to comply with additional restrictions related to offering reservations for accommodations, tours and activities or other travel services in such areas, we could be subject to increased legal and compliance costs, and our business, growth and results of operations could be adversely affected.

Compliance with the laws and regulations of multiple jurisdictions increases our cost of doing business. Examples of these laws and regulations, which vary and sometimes conflict, include the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and local laws which also prohibit corrupt payments to governmental officials or third parties, data privacy requirements, labor relations laws, non-discrimination, human rights or anti-human trafficking laws and regulations, such as the U.K. Modern Slavery Act 2015, tax laws, anti-trust or competition laws, U.S., E.U. or U.N. sanctioned country or sanctioned persons mandates and consumer protection laws. Violations of these laws and regulations could result in fines, penalties and/or criminal sanctions against us, our officers or our employees and/or prohibitions on the conduct of our business. Any such violations could also result in prohibitions on our ability to offer our services in one or more countries, delay or prevent potential acquisitions, and materially damage our reputation, our brands, our global expansion efforts, our ability to attract and retain employees and business partners, our business and our operating results. Even if we comply with these laws and regulations, doing business in certain jurisdictions or violations of these laws and regulations by the accommodations, restaurants, travel service providers or other parties with whom we conduct business could harm our reputation and brands, which could adversely affect our results of operations or stock price. In addition, these restrictions may provide a competitive advantage to our competitors unless they are also subject to comparable restrictions. Our success depends, in part, on our ability to anticipate these risks and manage these difficulties. We are also subject to a variety of other regulatory, legal and public policy risks and challenges in managing an organization operating in various countries, including those related to:

Prior to the COVID-19 pandemic, our business had grown substantially over the last several years as we expanded into new geographies and added new services. In addition, we have made efforts and expect to make further efforts to integrate access to travel services across our various brands. These changes add complexity to legal and tax compliance and our internal controls, and our size and operating history may increase the likelihood that we will be subject to regulatory scrutiny or audits by tax authorities in various jurisdictions. In addition, by virtue of Booking.com's size and presence in the Netherlands, it is required to have a supervisory board to oversee the strategy and operations of Booking.com. While the existence of the supervisory board has not had a significant impact on our operations, under certain circumstances, this governance structure could require Booking.com to obtain supervisory board approval in order to take certain actions, which could result in delays or other unanticipated strategic or operational challenges.

Our results have been and will likely continue to be negatively impacted by consumer purchases made using fraudulent credit cards, claims the consumer did not authorize the purchase or consumers who have closed bank accounts or have insufficient funds in their bank accounts to satisfy payments. We may be held liable for accepting fraudulent credit cards on our platforms or in connection with other fraudulent transactions on our platforms, as well as other payment disputes with consumers. Accordingly, we calculate and record an allowance for the resulting chargebacks. We must also continually implement and evolve measures to detect and reduce the risk of fraud, in particular as these methods become increasingly

We believe that an important component of our future success will be our ability to offer consumers their preferred method of payment in the most efficient manner on all our platforms, and, as a result, we are processing more of our transactions on a merchant basis where we facilitate payments from travelers through the use of credit cards and other payment methods (such as PayPal, Alipay, Paytm and WeChat Pay). While processing transactions on a merchant basis allows us to process transactions for properties that do not otherwise accept credit cards and to increase our ability to offer a variety of payment methods and flexible transaction terms to consumers, we incur additional payment processing costs (which are typically higher for foreign currency transactions) and other costs related to these transactions, such as costs related to fraudulent payments and transactions and fraud detection. As we expand our payments services to consumers and business partners, in addition to the revenues from these transactions, we may experience a significant increase in these costs, and our results of operations and profit margins could be materially adversely affected, in particular if we experience a significant increase in non-variable costs related to fraudulent payments and transactions.

As a greater percentage of our transactions involve us processing payments, our global systems and processes must be managed on a larger scale, which adds complexity, administrative burdens and costs and increases the demands on our systems and controls, which could adversely affect our results of operations. In addition, as our payment processing activities continue to develop, we expect to be subject to additional regulations, including financial services regulations, which we expect to result in increased compliance costs and complexities, including those associated with the implementation of new or advanced internal controls. For example, the E.U.'s Payment Services Directive 2 has further complicated the authentication process for accepting credit cards. As a result of this directive, payments made on our platforms by consumers in the European Economic Area are subject to Strong Customer Authentication, which requires the consumer to engage in additional steps to authenticate their transaction. This new requirement could cause consumer transactions to take longer to process or otherwise inconvenience the consumer, which could result in consumers choosing not to utilize our platforms as often or at all. The implementation of this process has resulted and may continue to result in increased compliance costs and administrative burdens for us. Other new or expanded regulations that could apply to us as our payments activities evolve include those relating to money transmission licenses, anti-money laundering, card scheme associations, sanctions, banking, privacy and security of our processes, among others. Compliance with this changing regulatory environment creates significant additional compliance costs and burdens or it could lead us to modify our business plans or operations, any of which could negatively impact our business, results of operations and profit margins.

We are also subject to payment card association rules and obligations under our contracts with the card schemes and our payment card processors, including the Payment Card Industry Data Security Standard (the "Standard"). Under the Standard and these association rules and obligations, if information is compromised, we could be liable to payment card issuers for associated expenses and penalties, and in some cases, we could be restricted in our ability to accept payment cards. Under certain circumstances in our agreements with the card schemes and in relation to the Standard, we are also subject to periodic audits, self-assessments and other assessments of our compliance with the rules and obligations of the payment card associations and the Standard, which could result in additional expenses and administrative burdens. In addition, if we fail to follow payment card industry security standards, even if no consumer information is compromised, we could incur significant fines or experience a significant increase in payment card transaction costs. Additionally, compliance with the Standard may not prevent all security incidents. If we are fined or required to pay additional processing fees or if our ability to accept payment cards is restricted in any way as a result of our failure to comply with these payment card industry rules, or otherwise, it could adversely impact our business, results of operations and profit margins.

We rely on banks, card schemes and other payment processors to execute certain components of the payments process. We generally pay these third parties interchange fees and other processing and gateway fees to help facilitate payments from consumers to travel service providers. As a result, if we are unable to maintain our relationships with these third parties on favorable terms or if these fees are increased for any reason, our profit margin, business and results of operations could be harmed. Additionally, if these third parties experience service disruptions or if they cease operations (whether as a result of the COVID-19 pandemic or otherwise), consumers and travel service providers could have difficulty making or receiving payments, which could adversely impact our reputation, business and results of operations.

In addition, in the event that one of our major travel service providers voluntarily or involuntarily declares bankruptcy or otherwise ceases or limits operations, we could experience an increase in chargebacks from customers with travel reservations with such travel service provider and we could experience financial loss from certain prepayments made to such travel service provider if we are not able to recover the prepayment. The COVID-19 pandemic and its resulting impact on travel demand, the travel industry and the economy increases the risk of insolvency or disruption to the ability of our travel service providers to provide services, and in some cases, has already resulted in the insolvency or closure of travel service

We regard our intellectual property as critical to our success, and we rely on domain name, trademark, copyright and patent law, trade secret protection 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 currently hold a number of issued patents in several jurisdictions. Further, in the future we may acquire additional patents or patent portfolios, which could require significant cash expenditures. However, we may choose not to patent or otherwise register some of our intellectual property and instead rely on trade secret or other means of protecting our intellectual property. We have licensed in the past, and may license in the future, certain of our proprietary rights, such as trademarks or copyrighted material, to third parties, and these licensees may take actions that diminish the value of our proprietary rights or harm our reputation. We also have procured various intellectual property licenses from third parties. In addition, effective intellectual property protection may not be available in every country in which our services are made available online, particularly in certain jurisdictions in which we operate in which theft of intellectual property may be more prevalent. We may 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 help to protect our business. We endeavor to defend our intellectual property rights diligently, but intellectual property litigation is extremely expensive and time-consuming, and may divert managerial attention and resources from our business objectives. We may not be able to successfully defend our intellectual property rights or they may not be sufficient to effectively protect our business, which could materially adversely affect our business, brands and results of operations.

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 relating to 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. Successful infringement claims against us could result in a significant monetary liability or prevent us from operating our business, or portions of our business, or require us to change business practices or develop non-infringing intellectual property, which could require significant effort and expense. In addition, resolution of claims may require us to obtain licenses to use intellectual property rights belonging to third parties, which may be expensive to procure, or possibly to cease using those rights altogether. Any of these events could have a material adverse effect on our business, results of operations and financial condition.

We use open source software in connection with our software development. From time to time, companies that use open source software have faced claims challenging the use of open source software and/or compliance with open source license terms. We could be subject to suits by parties claiming ownership of what we believe to be open source software, or claiming non-compliance with open source licensing terms. Some open source licenses require users who distribute software containing open source to make available all or part of such software, which in some circumstances could include valuable proprietary 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 to disclose our proprietary source code or that would otherwise breach the terms of an open source agreement, such use could inadvertently occur, in part because open source license terms are often ambiguous. Any requirement to disclose our proprietary source code or pay damages for breach of contract could be 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 continued access to sources of liquidity depends on multiple factors, including global economic conditions, the condition of global financial markets, the availability of sufficient amounts of financing, our ability to meet debt covenant requirements, our operating performance and our credit ratings. Since the COVID-19 pandemic, there has been increased volatility in the financial and securities markets, which has generally made access to capital less certain and increased the cost of obtaining new capital. Further, if our credit ratings were to be downgraded or if financing sources were to ascribe higher risk to our rating levels, our industry or us, our access to capital and the cost of any financing would be negatively impacted. We currently have $2.0 billion available under our revolving credit facility, which provides an additional potential source of liquidity. The revolving credit facility contains a maximum leverage ratio covenant, compliance with which is a condition to our ability to borrow thereunder. In April 2020, we amended the revolving credit facility, pursuant to which the maximum leverage ratio covenant was suspended through and including the three months ending March 31, 2021, and has been replaced with a $4.5 billion minimum liquidity covenant based on unrestricted cash, cash equivalents, short-term investments and unused capacity under this revolving credit facility. At December 31, 2020, we were in compliance with the minimum liquidity covenant. In October 2020, we amended the revolving credit facility to extend the suspension of the maximum leverage ratio covenant and the related replacement with the minimum liquidity covenant through and including the three months ending March 31, 2022 and increase the permitted maximum leverage ratio for a period of time following the three months ending March 31, 2022. There can be no assurance that we will be able to meet either the minimum liquidity covenant or the maximum leverage ratio covenant, as applicable, at any particular time, and our ability to borrow under the revolving credit facility depends on compliance with the applicable covenant. Further, the lenders have the right to require repayment of any amounts borrowed under the facility if we are not in compliance with the applicable covenant.

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 to movements in foreign currency exchange rates as the financial results of our international businesses are translated from local currency (principally Euros and British Pounds Sterling) into U.S. Dollars. When the U.S. Dollar strengthens against other currencies in which we transact, as it generally did in 2015, our foreign-currency-denominated net assets, gross bookings, revenues, operating expenses and net income are lower as expressed in U.S. Dollars. When the U.S. Dollar weakens against other currencies in which we transact, as it generally did in 2017 and 2018, our foreign-currency-denominated net assets, gross bookings, revenues, operating expenses and net income are higher as expressed in U.S. Dollars. Foreign currency exchange rate fluctuations on transactions denominated in currencies other than the functional currency result in gains and losses that are reflected in our financial results.

Recent years have seen significant volatility in the exchange rate between the Euro, the British Pound Sterling, the U.S. Dollar and other currencies. Significant fluctuations in foreign currency exchange rates can affect consumer travel behavior. For example, the strengthening of the U.S. Dollar relative to the Euro in 2015 made it more expensive for Europeans to travel to the United States. Consumers traveling from a country whose currency has weakened against other currencies may book lower ADR accommodations, choose to shorten or cancel their international travel plans or choose to travel domestically rather than internationally, any of which could adversely affect our gross bookings, revenues and results of operations, in particular when expressed in U.S. Dollars. Since the beginning of the COVID-19 pandemic, there has been an overall strengthening of the Euro and the British Pound Sterling relative to the U.S. Dollar. However, as a result of the travel restrictions and health concerns arising from the COVID-19 pandemic, we do not believe exchange rates have significantly altered consumer behavior since the pandemic began.

Volatility in foreign currency exchange rates and its impact on consumer behavior, which may differ across regions, make it more difficult to forecast industry and consumer trends and the timing and degree of their impact on our markets and business, which in turn makes it more difficult to manage our business and forecast our financial and operational performance.

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 the following, some of which are beyond our control:

Sales of a substantial number of shares of our common stock, including through the conversion of our convertible notes, could adversely affect the market price of our common stock by introducing a large number of sellers or short sellers to the market. Given the volatility that exists for our shares, such sales could cause the market price of our common stock to decline significantly. In addition, fluctuations in our stock price and our price-to-earnings multiple may have made or may make our stock attractive to momentum, hedge or day-trading investors who often shift funds into and out of stocks rapidly, exacerbating price fluctuations in either 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 extent that the public's perception of the prospects of internet or e-commerce or travel companies is negative, our stock price could decline, regardless of our results. Other broad market and industry factors may decrease the market price of our common stock, regardless of our operating performance. Market fluctuations, as well as general political and economic conditions, such as a recession, interest rate or foreign currency exchange rate fluctuations, political instability, changes in trade policy, trade disputes or a natural disaster, health concerns such as the COVID-19 pandemic, including any resurgences and the perceived pace or scale of any recovery from the pandemic, or a terrorist attack affecting a significant market for our business, such as Europe or the United States, could cause our stock price to decline. Negative market conditions could adversely affect our ability to raise 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 a company 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 the target of additional litigation. This additional litigation could result in substantial costs and divert management's attention and resources, either of which could adversely affect our business, financial condition and results of operations.

We have a substantial amount of outstanding indebtedness and we may incur substantial additional indebtedness in the future, including through public or private offerings of debt securities. Our outstanding indebtedness and any additional indebtedness we incur may have significant consequences, which may be amplified as our cash flow and earnings have decreased as a result of the COVID-19 pandemic and which could include:

Our ability to make payments of principal and interest on our indebtedness depends upon our future performance, which will be subject to the rate of economic and travel industry recovery as a result of the COVID-19 pandemic, general economic conditions, industry cycles and financial, business and other factors affecting our results of operations and financial condition, many of 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 be available 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.

We maintain an investment portfolio of various holdings, types and maturities. Our portfolio typically includes marketable debt securities, equity securities of publicly-traded companies, the values of which are subject to market price volatility, and investments in private companies. Investments in government and corporate debt securities and preferred stock classified as debt securities for accounting purposes are generally classified as available-for-sale and, consequently, are recorded in our balance sheets at fair value with unrealized gains or losses, net of tax, reported in "Accumulated other comprehensive loss" in the Consolidated Balance Sheets. Credit losses on such investments are recorded in the Consolidated Statement of Operations (see Notes 2 and 5 to our Consolidated Financial Statements). Changes in the fair values of our investments in publicly-traded equity securities are recognized in the Consolidated Statement of Operations. These changes could be volatile and they have had, and are likely to continue to have, a significant impact on our quarterly net income (or loss). Our investments in equity securities (other than those classified as debt securities for accounting purposes) of private companies are primarily measured at cost, less impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer, with changes in value also recognized in the Consolidated Statement of Operations (see Notes 2 and 5 to our Consolidated Financial Statements).

We have invested in Trip.com Group convertible notes. We have also invested in other Chinese internet companies (i.e., Meituan and Didi Chuxing). See Notes 5 and 6 to our Consolidated Financial Statements for more information regarding our investments in Trip.com Group, Meituan and Didi Chuxing securities. The value of these securities is subject to the risks associated with Trip.com Group's, Meituan's and Didi Chuxing's respective businesses, as well as any changes by the Chinese government in foreign investment laws or elevated scrutiny or regulation of foreign investments in Chinese companies. For example, Trip.com Group is a Cayman Islands company operating in China through what is commonly referred to as a variable interest entity, or VIE, structure where it conducts part of its business through contractual relationships with affiliated Chinese entities. Although VIE structures are commonly used by Chinese internet and e-commerce companies, there are substantial uncertainties regarding the interpretation and application of People's Republic of China ("PRC") laws and regulations to VIE structures, and it is possible that the PRC government may view the VIE structure as a violation of PRC law. VIE contractual relationships are not as effective in providing control over the affiliated Chinese companies as direct ownership, and Trip.com Group would have to rely on the PRC legal system to enforce those contracts in the event of a breach by one of these entities. Further, conflicts of interest could arise to the extent Trip.com Group's officers or directors are also shareholders, officers or directors of the affiliated Chinese entities. Any of these risks could materially and adversely affect Trip.com Group's business and therefore the value of our investment in Trip.com Group. Similar VIE-structure considerations and risks apply with respect to our investments in securities of Meituan and Didi Chuxing, each of which is a Cayman Islands company operating in China through a VIE structure.

Our investments in private companies are 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 become profitable, may not be able to secure additional funding or their technologies, services or products may not be successfully developed or introduced to the market. Further, our ability to liquidate any such investments is typically dependent on a liquidity event, such as a public offering or acquisition, as no public market exists for such securities. Valuations of privately-held companies are inherently complex and uncertain due to the lack of a liquid market for such securities. If we determine that any of our equity investments in such companies have experienced a decline in value, we are required to recognize the change in net income. For example, in the first quarter of 2020, we recognized an impairment of $100 million related to our investment in Didi Chuxing that resulted from the negative impact of the COVID-19 pandemic on Didi Chuxing's business. For investments classified as debt securities, any decline in value attributed to credit losses is also recognized in the Consolidated Statements of Operations.

We could lose the full amount of any of our investments, and any impairment of our investments have previously and could in the future have a material adverse effect on our financial condition and results of operations.

None.

 

 

We believe that our existing facilities are adequate to meet our current requirements, and that suitable additional or substitute space will be available as needed to accommodate any further expansion of corporate operations. Due to the impact of the COVID-19 pandemic on our business volumes, we took actions to reduce the size of our workforce to optimize efficiency and reduce costs. As a result of such actions, we have made and expect to make further changes to our facilities requirements.

The following table sets forth information relating to repurchases of our equity securities during the three months ended December 31, 2020:

On November 19, 2020, the SEC issued final rules to amend Regulation S-K. These changes are effective for annual filings for the first fiscal year ending on or after August 9, 2021 and early adoption is permitted. We elected to adopt the amendments to Item 301 of Regulation S-K in their entirety, which removed the requirement to furnish selected financial data for each of the last five fiscal years.

Our mission is to make it easier for everyone to experience the world. We seek to empower people to cut through travel barriers, such as money, time, language and overwhelming options, so they can use our services to easily and confidently go where they want to go, stay where they want to stay, dine where they want to dine, pay how they want to pay and experience what they want to experience. We connect consumers wishing to make travel reservations with providers of travel services around the world through our online platforms. Through one or more of our brands, consumers can: book a broad array of accommodations (including hotels, motels, resorts, homes, apartments, bed and breakfasts, hostels and other properties); make a car rental reservation or arrange for an airport taxi; make a dinner reservation; or book a flight, cruise, vacation package, tour or activity. Consumers can also use our meta-search services to easily compare travel reservation information, such as airline ticket, hotel reservation and rental car reservation information, from hundreds of online travel platforms at once. In addition, we offer various other services to consumers and partners, such as certain travel-related insurance products and restaurant management services to restaurants.

In response to the outbreak of the novel strain of the coronavirus, COVID-19 (the "COVID-19 pandemic"), many governments around the world have implemented, and continue to implement, a variety of measures to reduce the spread of COVID-19, including travel restrictions and bans, instructions to residents to practice social distancing, curfews, quarantine advisories, shelter-in-place orders and required closures of non-essential businesses. These government mandates have forced many of the partners on whom our business relies, including hotels and other accommodation providers, airlines and restaurants, to seek government support in order to continue operating, to curtail drastically their service offerings or to cease operations entirely. Further, these measures have materially adversely affected, and may further adversely affect, consumer sentiment and discretionary spending patterns, economies and financial markets, and our workforce, operations and customers. The COVID-19 pandemic and the resulting economic conditions and government orders have resulted in a material decrease in consumer spending and an unprecedented decline in travel and restaurant activities and consumer demand for related services. Our financial results and prospects are almost entirely dependent on the sale of travel-related services. Our results for the year ended December 31, 2020 have been materially and negatively impacted, with a material decline in gross travel bookings, room nights booked, total revenues, net income and cash flow from operations as compared to the year ended December 31, 2019. Newly-booked room night reservations, excluding the impact of cancellations, declined rapidly as the COVID-19 pandemic spread in the first quarter and the beginning of the second quarter of 2020, but then steadily improved through the end of the second quarter and into the summer travel period in the third quarter of 2020. However, in the fourth quarter of 2020, we saw an increased decline in newly-booked room night reservations, due in part to increased COVID-19 case counts and reimposed or additional government-imposed travel restrictions, particularly in Europe. In September 2020, a variant of COVID-19 that spreads more easily and quickly than other variants was first discovered in the United Kingdom, and has since spread across the country and to other countries, including the United States and in Europe. Another variant of COVID-19 that also appears to spread more easily and quickly than other variants was detected in South Africa in October 2020. In the fourth quarter of 2020, multiple COVID-19 vaccines were approved for widespread distribution throughout various parts of the world, including the United States and in Europe. While this news is encouraging, it is still unknown when these vaccines will be available to broader populations and whether they will be as effective against variants of COVID-19, including the variants mentioned above. We believe that as effective vaccines become widely distributed, people will feel it is safe to travel again and government restrictions will be relaxed, although the timing remains uncertain.

Since April 2020, we have seen a substantial year-over-year increase in the share of newly booked room nights booked for domestic travel (travelers booking a stay within their own country) while bookings for international travel have remained very limited throughout the pandemic. Over this same time period, we have seen a year-over-year increase in the share of our newly-booked room nights made on a mobile device. Also, while we saw an increase in the share of newly-booked room nights for alternative accommodation properties in the early months of the pandemic, more recently the share has been consistent with pre-pandemic levels. In addition, we have observed an improvement in cancellation rates since the high in April, though we have seen additional periods of highly elevated cancellation rates typically coinciding with newly imposed travel restrictions. The overall improvement in cancellation rates since April benefits our room nights booked including cancellations but does not impact newly-booked room nights.

Our revenue decline in 2020 was impacted to a greater extent than newly-booked room night growth due to the impact of higher cancellations and lower accommodation average daily rates ("ADRs") as compared to 2019. We expect to continue to see severely reduced new travel and restaurant reservation bookings as compared to 2019 levels for the foreseeable future, which will have a materially adverse impact on our business, financial condition, results of operations and cash flows. Further, given the volatility in the global travel industry and the financial difficulties faced by many of our travel service provider and restaurant partners, we have increased our provision for expected credit losses on receivables from and cash advances made to our travel service provider and restaurant partners.

Due to the uncertain and rapidly evolving nature of current conditions around the world, we are unable to predict accurately the impact that the COVID-19 pandemic will have on our business going forward. The approval and distribution of COVID-19 vaccines throughout the world is encouraging, however, the COVID-19 pandemic continues to impact global travel and travel restrictions remain in place, particularly in Europe. In the fourth quarter of 2020, we saw room nights decline further, as well as an increase in cancellation rates, in each case as compared to the third quarter of 2020. In January 2021, room nights declined slightly more than the decline in the fourth quarter of 2020, however, we have seen some improvement in these booking trends in recent weeks. If these recent trends were to continue, we currently expect that room nights and gross bookings in the first quarter of 2021 will decline relative to the first quarter of 2019 by a few percentage points less than those metrics declined in the fourth quarter of 2020 relative to the fourth quarter of 2019. We currently expect revenue in the first quarter of 2021 to decline by a similar amount as our expected decline in gross bookings in the first quarter of 2021, both relative to the first quarter of 2019. The comparison of the first quarter of 2021 to the first quarter of 2019 avoids the distortion created from comparing to the initial spread of the COVID-19 pandemic late in the first quarter of 2020. In addition, we

In response to the COVID-19 pandemic, we have taken and are taking various actions to address the impact of the pandemic on our business. Among other actions, we have:

Further, our Chief Executive Officer and the Chief Executive Officers of our brands voluntarily declined their salaries, certain other senior managers voluntarily reduced their salaries and our non-employee Directors voluntarily waived their cash fees for most of 2020.

In response to the reduction in our business volumes as a result of the impact of the COVID-19 pandemic, during the year ended December 31, 2020, we took actions at all of our brands to reduce the size of our workforce to optimize efficiency and reduce costs, which we expect to result in annualized cost savings of approximately $370 million in personnel-related expenses. In addition to the restructuring expenses recorded during the year ended December 31, 2020 and included in “Restructuring and other exit costs” in the Consolidated Statements of Operations, we estimate that we will record approximately $40 million of additional restructuring expenses in early 2021 (see Note 20 to our Consolidated Financial Statements). Our headcount decreased 23% year-over-year as of December 31, 2020, primarily due to the restructuring activities and attrition.

We have also been working with travelers and our travel service provider partners to deal with reservation cancellations and other disruptions arising from the impact of the pandemic. For example, when the pandemic started, Booking.com committed to allow cancellations of certain non-refundable bookings that were impacted by government travel restrictions and OpenTable has waived fees payable by restaurants for diners seated through OpenTable's online reservation service and subscription fees for many restaurants. The impacts of the COVID-19 pandemic are wide-ranging and affect all aspects of our business. As a result, the pandemic has negatively affected our financial results and condition as described throughout this Annual Report on Form 10-K. We anticipate that we will continue to make decisions and take actions to address the impacts of the pandemic on our business, including additional efforts to reduce costs while preserving our ability to offer valuable services to consumers and partners when the industry recovers. The full impact of the pandemic on our business is impossible to predict, and therefore we may recognize additional negative impacts to our operating results and financial condition in future periods as a result of the pandemic.

Certain governments have passed or are considering modifying legislation to help businesses during the COVID-19 pandemic through loans, wage subsidies, tax relief or other financial aid, and some of these governments have extended or are considering extending these programs. We have participated in several of these programs, including the Netherlands' wage subsidy program and the United Kingdom's job retention scheme. In addition, certain governments have extended support for the travel and tourism industry through special programs whereby discounts are extended to travelers through travel service providers or through travel agents for reservations facilitated by them. We have participated in Japan's Go To Travel program and Thailand's We Travel Together program.

Prior to the COVID-19 pandemic, we experienced many years of significant growth in our accommodation reservation services. We believe this growth was the result of, among other things, the broader shift of travel purchases from offline to online, the widespread adoption of mobile devices and the growth of travel overall. We also believe this growth was the result of the continued innovation and execution by our teams around the world to increase the number and the variety of accommodations we offer consumers, increase and improve content, build distribution and improve the consumer experience on our online platforms, as well as consistently and effectively marketing our brands through performance and brand marketing efforts. Prior to the COVID-19 pandemic, these year-over-year growth rates generally decelerated due to the size of our accommodation reservation business and the generally slowing growth rate of the online travel market. As the travel market recovers from the impact of the COVID-19 pandemic, we expect to see higher than pre-COVID-19 pandemic growth rates until we return to the level of travel market demand that we observed prior to the COVID-19 pandemic, after which we expect prior trends to generally resume.

We are a global business, and online travel growth rates vary across the world depending on numerous factors, including local and regional economic conditions, individual disposable income, access to the internet and adoption of e-commerce. Over the last several years, and prior to the COVID-19 pandemic, online travel growth rates had generally slowed in markets such as North America and Europe where online activity was high and consumers had been engaging in e-commerce transactions for many years, while online travel growth rates remained relatively high in markets such as Asia-Pacific where incomes were rising more quickly and the increased availability and use of mobile devices had accelerated the growth of internet usage and travel e-commerce transactions. Over the long term, we expect the broader global economy and online travel market to recover from the COVID-19 pandemic, and following the recovery of the travel industry to the level of pre-COVID-19 pandemic demand, we would expect online travel growth rates will slow as markets continue to mature. However, we believe that the opportunity to grow our business beyond pre-COVID-19 pandemic levels exists for the markets in which we operate, including in both mature and less mature markets. Further, we believe that this opportunity for growth exists because we believe we provide significant value to travel service providers, regardless of size or geography, due to our global reach and marketing expertise. For example, we believe that accommodation providers of all sizes, from large hotel chains to small, independent hotels and alternative accommodations such as homes and apartments, benefit from using our services, which enable them to reach a broader audience of potential customers.

Historically, our growth has primarily been generated by the worldwide accommodation reservation business of Booking.com, which is our most significant brand, and has been due, in part, to the availability of a large number of properties through Booking.com. Booking.com included approximately 2,373,000 properties on its website at December 31, 2020, consisting of approximately 434,000 hotels, motels and resorts and approximately 1,939,000 homes, apartments and other unique places to stay, compared to approximately 2,580,000 properties (including approximately 460,000 hotels, motels and resorts and approximately 2,120,000 homes, apartments, and other unique places to stay) at December 31, 2019. Booking.com categorizes properties listed on its website as either (a) hotels, motels and resorts, which groups together more traditional accommodation types (including hostels and inns), or (b) homes, apartments and other unique places to stay, also referred to as alternative accommodations, which encompasses all other types of accommodations, including bed and breakfasts, villas, apart-hotels and beyond.

We intend to continue to improve the accommodation choices available for reservation on our platforms, however, the number of accommodations on our platforms may vary in part as a result of removing accommodations from time to time. At December 31, 2020, we saw a year-over-year decrease in the number of properties on Booking.com’s website, as compared to December 31, 2019, driven by an elevated number of accommodations removed from the platform due primarily to the properties not providing availability on our platforms, non-payment of invoices, or property closures. We have continued to see a year-over-year increase in the number of accommodations removed from our platform during the COVID-19 pandemic, and we expect to see further accommodation removals in the future due to increases in property closures or changes in ownership.

Many of the newer accommodations we add to our travel reservation services, especially in highly-penetrated markets, may have fewer rooms or higher credit risk and may appeal to a smaller subset of consumers (e.g., hostels and bed and breakfasts). Because alternative accommodations are often either a single unit or a small collection of independent units, these properties generally represent more limited booking opportunities than hotels, motels and resorts, which generally have more units to rent per property. Further, alternative accommodations in general may be subject to increased seasonality due to local tourism seasons or other factors or may not be available at peak times due to use by the property owners. We may also experience lower profit margins with respect to these properties due to certain additional costs, such as increased customer service costs, related to offering these accommodations on our platforms. As our alternative accommodation business has grown, these different characteristics have negatively impacted our profit margins and we expect this trend to continue. Further, to the extent that these properties represent an increasing percentage of the properties on our platforms, the number of reservations per property will likely continue to decrease since alternative accommodation properties typically have fewer

We are constantly innovating to grow our business by, among other things, providing a best-in-class user experience with intuitive, easy-to-use online platforms (i.e., websites and mobile apps) to ensure that we are meeting the needs of online consumers while aiming to exceed their expectations. As part of these ongoing efforts, we have a long-term strategy to build a more integrated offering of multiple elements of travel, which we refer to as the "Connected Trip", and we expect these efforts to increase room night growth and revenue growth over time. Although we expect our efforts to build the Connected Trip will increase revenue growth over time, we may see a negative impact on our operating margins in the near term as we incur the expenses associated with these investments. Further, to the extent our non-accommodation services grow faster than our accommodation services, whether as part of the Connected Trip or otherwise, our operating margins may be negatively affected if we experience an increasing mix of revenues from lower-margin services.

As part of our strategy to provide more payment options to consumers and travel service providers, increase the number and variety of accommodations available on Booking.com and enable the growth of our in-destination activities businesses, Booking.com is increasingly processing transactions on a merchant basis, where it facilitates payments from travelers for the services provided. This allows Booking.com to process transactions for travel service providers and to increase its ability to offer secure and flexible transaction terms to consumers, such as the form and timing of payment. We believe that adding these types of service offerings will benefit consumers and travel service providers, as well as our gross bookings, room night and earnings growth rates. However, this results in additional expenses for personnel, payment processing, customer chargebacks (including those related to fraud) and other expenses related to these transactions, which are recorded in "Personnel" and "Sales and other expenses" in our Consolidated Statements of Operations, as well as associated incremental revenues in the form of credit card rebates, for example, which are recorded in "Merchant revenues." To the extent more of our business is generated on a merchant basis, we will incur a greater level of these merchant-related expenses, which would negatively impact our operating margins despite increases in associated incremental revenues. Components of revenues and expenses related to our merchant business may be recognized in different periods. These timing factors could impact our operating margins as well as the relationship between our gross bookings and revenues in a particular period, especially as our merchant business increases as a percentage of our overall business.

We compete globally with both online and traditional providers of travel and restaurant reservation and related services. The markets for the services we offer are intensely competitive, constantly evolving and subject to rapid change, and current and new competitors can launch new services at relatively low cost. Some of our current and potential competitors, such as Google, Apple, Alibaba, Tencent, Amazon and Facebook, have significantly more customers or users, consumer data and financial and other resources 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 compete more effectively with us. For example, Google has entered various aspects of the online travel market and has grown rapidly in this area, including by offering a flight meta-search product (Google Flights), a hotel meta-search product (Google Hotel Ads), a vacation rental meta-search product, its "Book on Google" reservation functionality, Google Travel, a planning tool that aggregates its flight, hotel and packages products in one website and by integrating its hotel meta-search products and restaurant information and reservation products into its Google Maps app. Moreover, as the economy and the travel industry recover from the impact of the COVID-19 pandemic, the structure of the travel industry could change in unexpected ways, which could advantage or disadvantage us and benefit certain of our existing competitors or new entrants. As a result, our historical strengths may not provide the competitive advantages that they did prior to the pandemic. If we are unable to successfully adapt to any changes in how the travel industry operates or to changes in the ways in which consumers purchase travel services, our ability to compete, and therefore our business and results of operations, would be adversely affected.

Although we believe that providing an extensive collection of properties, excellent customer service and an intuitive, easy-to-use consumer experience are important factors influencing a consumer's decision to make a reservation, for many consumers, particularly in certain markets, the price of the travel service is the primary factor determining whether a consumer will book a reservation. As a result, it is increasingly important to offer travel services, such as accommodation reservations, at competitive prices, whether through discounts, coupons, closed-user group rates or loyalty programs, or otherwise. These initiatives have resulted and in the future may result in lower ADRs and lower revenue as a percentage of gross bookings. Discounting and couponing coupled with a high degree of consumer shopping behavior is particularly common in Asian markets. In some cases, our competitors are willing to make little or no profit on a transaction, or offer travel services at a loss, in order to gain market share.

We have experienced a meaningful decline in constant-currency accommodation ADRs since the outbreak of the COVID-19 pandemic and it is uncertain how long the COVID-19 pandemic will impact our ADRs. These declining ADR trends have resulted in and may continue to result in our gross bookings growing at a lower rate of growth than our accommodation room nights. Prior to the outbreak, we observed a trend of declining constant-currency accommodation ADRs. We believe the trend of declining ADRs, observed prior to the outbreak, was partially driven by the negative impact of the changing geographical mix of our business (e.g., lower ADR regions like Asia-Pacific are generally growing faster than higher ADR regions like Western Europe) as well as pricing pressures within local markets from time to time which resulted from competitive conditions, weakening economic conditions or changes in travel patterns. As the travel market recovers from the impact of the COVID-19 pandemic, we expect travel industry ADRs generally to increase and, as a result, we expect our ADRs similarly to increase during the recovery, however, it is uncertain whether industry ADRs will improve at the same pace as travel demand. In addition, we expect the ADR trends we observed before the COVID-19 pandemic will generally resume after the recovery, which would negatively pressure our ADRs, however, there may also be periods of stable or increasing ADRs.

We have established widely used and recognized e-commerce brands through marketing and promotional campaigns. Historically, our marketing expenses increased significantly, however, we experienced more moderate growth rates in recent years, and since the COVID-19 pandemic, our marketing expenses have declined significantly. Our marketing expense is comprised of performance marketing and brand marketing expenses. Our performance marketing expense, which represents a substantial majority of our marketing expense, is primarily related to the use of online search engines (primarily Google), meta-search and travel research services and affiliate marketing to generate traffic to our websites. Our brand marketing expense is primarily related to costs associated with producing and airing television advertising, online video advertising (for example, on YouTube and Facebook), online display advertising and other brand marketing. Total marketing expenses were $2.2 billion and $5.0 billion for the years ended December 31, 2020 and 2019, respectively. We expect that our marketing expenses in 2021 will remain significantly below 2019 levels.

Marketing efficiency, expressed as marketing expense as a percentage of total revenues, is impacted by a number of factors that are subject to variability and that are, in some cases, outside of our control, including ADRs, costs per click, cancellation rates, foreign currency exchange rates, our ability to convert paid traffic to booking customers, the timing difference between when revenue is recognized and when marketing expense is recorded, the timing and effectiveness of our brand marketing campaigns and the extent to which consumers come directly to our platforms for bookings. For example, competition for desired rankings in search results and/or a decline in ad clicks by consumers could increase our costs per click and reduce our marketing efficiency. Changes by Google or any of our other search or meta-search partners in how it presents travel search results, including, if applicable, by placing its own offerings at or near the top of search results, or the manner in which it conducts the auction for placement among search results may be competitively disadvantageous to us and may impact our ability to efficiently generate traffic to our websites.

In recent years, we experienced significant increases in our cancellation rates, which negatively affected our marketing efficiency and results of operations. However, from the third quarter of 2018 until the fourth quarter of 2019, our cancellation rates generally decreased, which benefited our marketing efficiency and results of operations. Since the COVID-19 pandemic we have experienced unprecedented increases in cancellation rates, which negatively impacted our marketing efficiency and results of operations. For example, increased cancellations, especially early in the pandemic, have resulted in increased customer service costs, as well as higher than normal cash outlays to refund consumers for prepaid reservations. However, in the second and third quarters of 2020, we saw a steady improvement in cancellation rates, which trended towards levels that we observed prior to the COVID-19 pandemic. In the fourth quarter of 2020, we saw a reversal of the improving cancellation rate trend. We expect to continue to see volatility in cancellation rates due to any resurgences of the pandemic leading to reinstituted or additional travel restrictions, shelter-in-place rules and reduced willingness to travel. Further, in the fourth quarter of 2020, a higher share of our newly-booked room night reservations were made with flexible cancellation policies, as compared to the corresponding period in 2019, which could result in higher than normal cancellation rates in future quarters.

We generally enter into derivative instruments to minimize the impact of foreign currency exchange rate fluctuations on our transactional balances denominated in currencies other than the functional currency. In periods prior to the second quarter of 2020, we also entered into derivative instruments to minimize the impact of short-term foreign currency exchange rate fluctuations on the translation of our consolidated operating results into U.S. Dollars. However, these instruments were short-term in nature and not designed to hedge against currency fluctuations that could impact growth rates for our gross bookings or revenues. Since the first quarter of 2020, we have not entered into such derivative instruments as the impact of the

In recent years, the majority of our gross bookings have been generated in the first half of the year, as consumers planned and reserved their spring and summer vacations in Europe and North America. However, we would generally recognize revenue from these bookings when the travel begins (at "check-in"), which can be in a quarter other than when the associated reservations are booked. In contrast, we expensed the substantial majority of our marketing activities as the expense is incurred, which, in the case of marketing in particular, is typically in the quarter in which associated reservations were booked. As a result of this timing difference between when we recorded marketing expense and when we recognized associated revenue, we have experienced our highest levels of profitability in the third quarter of the year, which is when we experienced the highest levels of accommodation check-ins for the year for our European and North American markets. The first quarter of the year was typically the quarter in which we recognized the lowest amount of revenue as well as the lowest level of profitability and highest level of volatility in earnings growth rates due to these seasonal timing factors. The COVID-19 pandemic impacted seasonality in 2020; for example, we witnessed a higher share of travel being booked during the second and third quarters as well as a higher share of stays during the third quarter than in prior years. We cannot currently predict travel patterns given the COVID-19 pandemic, and we may not experience typical seasonality effects on our business in 2021.

For several years, we experienced an expansion of the booking window (the average time between the booking of a travel reservation and when the travel begins), which impacts the relationship between our gross bookings (recognized at the time of booking) and our revenues (recognized at the time of check-in).  However, we saw a contraction of the booking window throughout 2018 and 2019. Due to the impact of the COVID-19 pandemic on our booking trends, we saw an initial expansion in the booking window in the second quarter versus the comparable prior-year period as an increased percentage of newly-booked room nights were made for travel occurring in the third quarter. However, in the third and fourth quarters, we saw a significant contraction of the booking window versus the comparable prior-year period as an increased percentage of newly-

In addition, the date on which certain holidays fall can have an impact on our quarterly results. For example, in 2019, Easter fell on April 21 and Easter-related travel began in the second quarter, when the associated revenue was recognized. By comparison, in 2018, Easter was on April 1 and a meaningful amount of Easter-related travel began in the week leading up to the holiday with the associated revenue being recognized in the first quarter of 2018.  As a result of the shift in Easter timing relative to 2018, our first quarter 2019 year-over-year growth rates in revenue, operating income and operating margins were negatively impacted and our second quarter 2019 year-over-year growth rates were positively impacted.  In 2020, Easter fell on April 12, in the second quarter as it did in 2019, and as a result we did not experience a meaningful impact to our year-over-year growth rates in 2020 from the Easter holiday. Due to the significant reduction in travel demand related to the COVID-19 pandemic, we do not expect the timing of the Easter holiday to have a meaningful impact on our growth rates in 2021. The timing of other holidays such as 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 our gross bookings growth rate substantially decelerates, our operating margins typically benefit from relatively less variable marketing expense. In addition, revenue growth is typically less impacted by decelerating gross bookings growth in the near term due to the benefit of revenue related to reservations booked in previous quarters, but any such deceleration would negatively impact revenue growth in subsequent periods. Conversely, in periods where our gross bookings growth rate accelerates, our operating margins are typically negatively impacted by relatively more variable marketing expense. In addition, revenue growth is typically less impacted by accelerating gross bookings growth in the near term, but any such acceleration would positively impact revenue growth in subsequent periods as a portion of the revenue recognized from such gross bookings will occur in future quarters. As the travel market recovers from the impact of the COVID-19 pandemic, we expect to see higher than pre-COVID-19 pandemic growth rates, which will likely result in periods where our operating margins are negatively impacted due to the timing difference of when marketing expense is recorded and when revenue is recognized.

The extent of the effects of the COVID-19 pandemic on our business, results of operations, cash flows and growth prospects is highly uncertain and will ultimately depend on future developments. We expect the pandemic and its effects to continue to have a significant adverse impact on our business for the duration of the pandemic and during the subsequent economic recovery, which could be an extended period of time. Over the long-term, 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. In recent years, we have experienced pressure on operating margins as we invested in initiatives to drive future growth. We also intend to broaden the scope of our business, and to that end, we explore strategic alternatives from time to time in the form of, among other things, acquisitions. We believe competitive pressure to innovate will encompass a wider range of services and technologies, including services and technologies that may be outside of our historical core business, and our ability to keep pace may slow. Potential competitors, such as emerging start-ups, may be able to innovate and focus on developing a particularly new product or service faster than we can or may foresee consumer need for new services or technologies before us. Some of our larger competitors or potential

Management'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 ("U.S. GAAP"). Our significant accounting policies and estimates are more fully described in Note 2 to our Consolidated Financial Statements. Certain of our accounting estimates are particularly important to our financial position and results of operations and require us to make difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Our management uses its judgment to determine the appropriate assumptions to be used in the determination of certain estimates. We evaluate our estimates on an ongoing basis. Estimates are based on, among other things, historical experience, terms of existing contracts, our observance of trends in the travel industry and on various other assumptions that we believe to be reasonable under the circumstances. Our actual results may differ from these estimates under different assumptions or conditions. Our critical accounting policies that involve significant estimates and judgments of management include the following:

The application of the acquisition accounting for business combinations requires the use of significant estimates and assumptions to determine the fair value of the assets acquired and liabilities assumed. Our estimates of the fair value are based upon assumptions that we believe are reasonable. When we deem appropriate, we utilize assistance from a third-party valuation firm. The consideration transferred is allocated to the assets acquired and liabilities assumed based on their respective fair values at the acquisition date. The excess of the consideration transferred over the net of the amounts allocated to the identifiable assets acquired and liabilities assumed is recognized as goodwill. Goodwill is assigned to reporting units that are expected to benefit from the synergies of the business combination as of the acquisition date.

A substantial portion of our intangible assets and goodwill relates to the acquisitions of OpenTable and KAYAK.

We review long-lived assets whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable.  The assessment of possible impairment is based upon the ability to recover the carrying value of the assets from the estimated undiscounted future net cash flows, before interest and taxes, of the related asset group.

Due to the significant and negative financial impact of the COVID-19 pandemic, we performed the recoverability test of our long-lived assets and concluded there was no impairment at March 31, 2020. For OpenTable and KAYAK, we tested the recoverability of the long-lived assets and concluded there was no impairment at September 30, 2020. We did not identify any additional impairment indicators for our long-lived assets at December 31, 2020.

We test goodwill for impairment annually and whenever an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. We test goodwill at a reporting unit level. Our annual goodwill impairment tests are performed as of September 30.

Due to the significant and negative financial impact of the COVID-19 pandemic, we performed an interim period goodwill impairment test at March 31, 2020. Under the current goodwill impairment standard adopted in the first quarter of 2020, a goodwill impairment loss is measured at the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill (see Note 2 to our Consolidated Financial Statements).

As of March 31, 2020, the estimated fair value of each of our reporting units, except the OpenTable and KAYAK reporting unit, substantially exceeded its respective carrying value. For the OpenTable and KAYAK reporting unit, we recognized a goodwill impairment charge of $489 million for the three months ended March 31, 2020, which is not tax-

The estimated fair value of OpenTable and KAYAK was determined using a combination of standard valuation techniques, including an income approach (discounted cash flows) and a market approach (applying the recent decline in enterprise values of comparable publicly-traded companies to the recently calculated fair value for OpenTable and KAYAK as well as applying comparable company multiples).

The income approach estimates fair value utilizing long-term growth rates and discount rates applied to the cash flow projections. In the cash flow projections, we assumed that OpenTable and KAYAK will experience a significant decline in near-term cash flows with a recovery to 2019 levels of financial performance (including profitability) occurring in 2023. The shape and timing of the recovery was a key assumption in our fair value calculation (both in the income and market approaches).

As of September 30, 2020, we performed our annual goodwill impairment test. Other than the OpenTable and KAYAK reporting unit, the fair values of our reporting units substantially exceeded their respective carrying values.

For the OpenTable and KAYAK reporting unit, we recognized a goodwill impairment charge of $573 million for the three months ended September 30, 2020, which is not tax-deductible, resulting in an adjusted carrying value of goodwill for OpenTable and KAYAK of $1.0 billion at September 30, 2020. The goodwill impairment was primarily driven by a significant reduction in the forecasted cash flows of OpenTable and KAYAK, reflecting a longer assumed recovery period to 2019 levels of profitability, mainly due to the continued material adverse impact of the COVID-19 pandemic, including its impact on the flight vertical at KAYAK, and the lowered outlook for monetization opportunities in restaurant reservation services.

The estimated fair value of OpenTable and KAYAK was determined using a combination of standard valuation techniques, including an income approach (discounted cash flows) and a market approach (applying comparable company multiples).

The income approach estimates fair value utilizing long-term growth rates and discount rates applied to the cash flow projections. The income approach, applied as of September 30, 2020, reflected a reduction in the forecasted cash flows of OpenTable and KAYAK and a longer assumed recovery period to 2019 levels of profitability, driven primarily by a lowered outlook for monetization opportunities in restaurant reservation services and slower than previously expected recovery trends for airline travel, which is a key vertical for KAYAK. For the interim goodwill impairment test at March 31, 2020, we expected a recovery to 2019 levels of financial performance occurring in 2023 for OpenTable and KAYAK. Based on our evaluation of all relevant information available as of September 30, 2020 for the annual goodwill impairment test, we expected that OpenTable and KAYAK would not return to the 2019 level of profitability within the next five years, and that it was uncertain whether the shape of the recovery would ultimately match our expectations. An increase or decrease of one percentage point to the profitability growth rates used in the cash flow projections would result in an increase or decrease of approximately $100 million to the estimated fair value of OpenTable and KAYAK at September 30, 2020. The discount rate is determined based on the reporting unit’s estimated weighted-average cost of capital and adjusted to reflect the risks inherent in its cash flows, which requires significant judgments. The discount rate used for the annual goodwill impairment test as of September 30, 2020 is higher than the discount rate used for the interim goodwill impairment test as of March 31, 2020. If the discount rate used in the income approach increases or decreases by 0.5%, the impact to the estimated fair value of OpenTable and KAYAK, at September 30, 2020, ranges from a decrease of approximately $65 million to an increase of approximately $70 million.

The estimation of fair value reflects numerous assumptions that are subject to various risks and uncertainties, including key assumptions regarding OpenTable and KAYAK’s expected growth rates and operating margin, expected length and severity of the impact from the COVID-19 pandemic, the shape and timing of the subsequent recovery and the competitive environment, as well as other key assumptions with respect to matters outside of our control, such as discount rates and market comparables. It requires significant judgments and estimates and actual results could be materially different than the judgments and estimates used to estimate fair value. Future events and changing market conditions may lead us to re-evaluate the assumptions reflected in the current forecast disclosed above, particularly the assumptions related to the length and severity of the COVID-19 pandemic and the shape and timing of the subsequent recovery, which may result in a need to recognize an additional goodwill impairment charge that could have a material adverse effect on our results of operations.

See Note 5 to our Consolidated Financial Statements for additional information related to the investments in private companies. The fair value of these investments are measured using unobservable inputs when little or no market data is available ("Level 3 inputs"). See Note 6 to our Consolidated Financial Statements for additional information.

Our investments measured using Level 3 inputs primarily consist of preferred stock investments in privately-held companies that are classified as either debt securities or equity securities without readily determinable fair values. Fair values of privately held securities are estimated using a variety of valuation methodologies, including both market and income approaches. We have used valuation techniques appropriate for the type of investment and the information available about the investee as of the valuation date to determine fair value. Recent financing transactions in the investee, such as new investments in preferred stock, are generally considered the best indication of the enterprise value and therefore used as a basis to estimate fair value. However, based on a number of factors, such as the proximity in timing to the valuation date or the volume or other terms of these financing transactions, we may also use other valuation techniques to supplement this data, including the income approach. In addition, an option-pricing model (“OPM”) is utilized to allocate value to the various classes of securities of the investee, including the class owned by us. The model includes assumptions around the investees’ expected time to liquidity and volatility.

Our investment in Grab, which is classified as a debt security for accounting purposes, had an aggregate estimated fair value of $200 million at December 31, 2020 and 2019. We measured this investment using "Level 3" inputs and management's estimates that incorporate current market participant expectations of future cash flows considered alongside recent financing transactions of the investee and other relevant information.

We performed an impairment analysis on the investment in Didi Chuxing at March 31, 2020 considering the impact of the COVID-19 pandemic, which resulted in an adjusted carrying value of $400 million at March 31, 2020 and December 31, 2020. No additional impairment indicators were identified as of December 31, 2020. As discussed below, we used unobservable inputs in order to determine fair value. We used an income approach in estimating the fair value of Didi Chuxing as of March 31, 2020. The income approach estimates value based on the expectation of future cash flows that a company will generate. These future cash flows are discounted to their present values using a discount rate based on a company’s weighted- average cost of capital, and is adjusted to reflect the risks inherent in its cash flows. The key unobservable inputs and ranges used include the weighted average cost of capital (12%-14%), terminal Earnings before interest, taxes, depreciation and amortization (“EBITDA”) multiple (13x-15x), volatility (60%-70%) and an estimated time to liquidity of 4 years. Significant changes in any of these inputs in isolation would result in significantly different fair value measurements. Generally, a change in the assumption used for terminal EBITDA multiples would result in a directionally similar change in the fair value and a change in the assumption used for weighted average cost of capital or volatility would result in a directionally opposite change in the fair value.

We regularly review our deferred tax assets for recoverability considering historical profitability, projected future taxable income, the expected timing of the reversals of temporary differences and tax planning strategies and record valuation allowances as required.

We are subject to ongoing tax examinations and assessments in various jurisdictions. We have been audited in many jurisdictions and, from time to time, face challenges from the tax authorities regarding the amount of taxes due. These challenges include questions regarding the timing and amount of deductions that we have taken on our tax returns. Although we believe that our tax filing positions are reasonable and comply with applicable law, we regularly review our tax filing positions, especially in light of tax law or business practice changes, and we may change our positions or determine that previous positions should be amended, either of which could result in additional tax liabilities. The final determination of tax audits or tax disputes may be different from what is reflected in our historical income tax provisions and accruals.

The evaluation of tax positions and recognition of income tax benefits require significant judgment and we consult with external tax and legal counsel, as appropriate. We consider the technical merits of our tax positions along with the applicable tax statutes, related interpretations and precedents and our expectation of the outcome of proceedings (or negotiations) with tax authorities. We recognize liabilities when we believe that uncertain positions may not be fully sustained upon audit by the tax authorities, including any related appeals or litigation processes. Liabilities recognized for uncertain tax positions are based on a two-step approach for recognition and measurement. First, we evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained based on its technical merits. Second, we measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Interest and penalties attributable to uncertain tax positions, if any, are recognized as a component of income tax expense. The tax benefits ultimately realized by us may be different than what is recorded in the financial statements due to future events such as our settling the matter with the tax authorities and our success in sustaining our tax positions.

See Notes 15 and 16 to our Consolidated Financial Statements for further information.

Loss contingencies (other than income tax-related contingencies disclosed above) arise from actual or possible claims and assessments and pending or threatened litigation that may be brought against us by individuals, governments or other entities. Based on our assessment of loss contingencies at each balance sheet date, a loss is recorded in the financial statements if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. If the amount of the loss cannot be reasonably estimated, we disclose information about the contingency in the financial statements. We also disclose information in our financial statements about reasonably possible loss contingencies.

The determination of whether a loss is probable and whether the amount of the loss can be reasonably estimated requires significant judgment and evaluation of all the underlying facts and circumstances, including judgments about the potential actions of third-party claimants, regulatory authorities and courts. Claims, assessments and litigations involve significant uncertainties such as the complexity of the facts, the legal theories involved, the nature of the claims, the judgment of the courts, the applicable methodology for determining potential damages and, in the case of class actions, whether a class action can be certified, the extent to which members of a class would or would not file a claim and the uncertainty inherent in class actions.

On a quarterly basis, we update our analysis and estimates considering all available information, including the impact of negotiations, settlements, rulings and advice of legal counsel. Changes in our assessment of whether a loss is probable, our estimate of the loss, or our determination of whether the amount of loss can be reasonably estimated could have a material impact on our results of operations and financial position. Changes in our assumptions regarding a particular matter or the effectiveness of our strategies related to legal and other proceedings could also have a material impact on our results of operations and financial position. For all loss contingencies, until a matter is finally resolved, there may be an exposure to loss in excess of the liability accrued for the matter and such amounts could be material.

See Note 16 to our Consolidated Financial Statements for further information.

 

 

Our financial results are driven by certain operating metrics that encompass the booking and other business activity generated by our travel and travel-related services.  Specifically, reservations of accommodation room nights, rental car days and airline tickets capture the volume of units booked through our OTC brands by our travel reservation services customers.  Gross bookings is an operating and statistical metric that captures the total dollar value, generally inclusive of taxes and fees, of all travel services booked through our OTC brands by our customers, net of cancellations, and is widely used in the travel business. Our non-OTC brands (KAYAK and OpenTable) have different business metrics from those of our OTC brands and therefore search queries through KAYAK and restaurant reservations through OpenTable do not contribute to our gross bookings.

Accommodation room nights, rental car days and airline tickets reserved through our services for the years ended December 31, 2020 and 2019 were as follows:

 

Accommodation room nights, rental car days and airline tickets reserved through our services each declined for the year ended December 31, 2020, compared to the year ended December 31, 2019, due to the COVID-19 pandemic, which drove a substantial decline in new travel bookings and increased cancellation rates.

Gross bookings resulting from reservations of accommodation room nights, rental car days and airline tickets made through our agency and merchant models for the years ended December 31, 2020 and 2019 were as follows (numbers may not total due to rounding): 

Gross bookings decreased by 63.3% for the year ended December 31, 2020, compared to the year ended December 31, 2019 (decreased on a constant-currency basis by approximately 63%), almost entirely due to the 58.0% decline in accommodation room night reservations, as well as a decline in accommodation ADRs of approximately 14% on a constant-currency basis for the year ended December 31, 2020, compared to the year ended December 31, 2019. We believe that unit growth rates and growth in total gross bookings on a constant-currency basis, which excludes the impact of foreign currency exchange rate fluctuations, 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 from travelers for the travel services provided. Agency gross bookings decreased by 65.4% for the year ended December 31, 2020, compared to the year ended December 31, 2019, almost entirely due to a decrease in gross bookings from agency accommodation room night reservations at Booking.com.

Merchant gross bookings are derived from services where we facilitate payments from travelers for the travel services provided. Merchant gross bookings decreased by 57.7% for the year ended December 31, 2020, compared to the year ended December 31, 2019, principally due to a decrease in gross bookings from our merchant accommodation reservation services at Booking.com, agoda and Priceline. Merchant gross bookings for the year ended December 31, 2020, compared to the year ended December 31, 2019, declined less than agency gross bookings due to the stronger growth of merchant gross bookings early in the year as Booking.com had been expanding its merchant accommodation reservation services prior to the COVID-19 pandemic, as well as due to relatively better performance from our merchant travel reservation services at Priceline.

 

Substantially all of our revenues are generated by providing online travel reservation services, which facilitate online travel purchases between travel service providers and travelers.

Revenues from online travel reservation services are classified into two categories:

 

 

Advertising and other revenues are derived primarily from (1) revenues earned by KAYAK for (a) sending referrals to OTCs and travel service providers and (b) advertising placements on its platforms; and (2) revenues earned by OpenTable for (a) restaurant reservation services (fees paid by restaurants for diners seated through OpenTable's online reservation service) and (b) subscription fees for restaurant management services.

Total revenues for the year ended December 31, 2020, as compared to the year ended December 31, 2019, respectively, decreased by 54.9% (decreased on a constant-currency basis by approximately 55%). A significant majority of the year-over-year decrease was related to revenues from our accommodation reservation services. Total revenues for the year ended December 31, 2020 were negatively impacted by a reduction in revenue of $44 million for refunds paid or estimated to be payable to travelers as a result of the COVID-19 pandemic where we agreed to provide free cancellation for certain non-refundable reservations without a corresponding estimated expected recovery from the travel service providers (see Notes 2 and 3 to the Consolidated Financial Statements). In addition, total revenues for the year ended December 31, 2020 were negatively impacted by additional rebates of approximately $100 million offered to travel service providers meeting certain eligibility requirements under an incentive program that ended in 2020 (see Note 3 to the Consolidated Financial Statements).

Agency revenues decreased by 57.4% for the year ended December 31, 2020, compared to the year ended December 31, 2019, due to the ongoing impacts of the COVID-19 pandemic.

Merchant revenues decreased by 44.7% for the year ended December 31, 2020, compared to the year ended December 31, 2019, due primarily to decreases in gross bookings from our merchant accommodation reservation services and merchant rental car reservation services due to the ongoing impacts of the COVID-19 pandemic.

Advertising and other revenues decreased by 67.3% for the year ended December 31, 2020, compared to the year ended December 31, 2019, primarily due to the COVID-19 pandemic, which resulted in a decline in consumer demand for the travel and restaurant-related services offered by KAYAK and OpenTable. In addition, advertising and other revenue related to OpenTable has been further impacted by a program that waived fees payable by restaurants for diners seated through OpenTable's online reservation service and subscription fees for many restaurants.

Total revenues as a percentage of gross bookings was 19.2% for the year ended December 31, 2020 as compared to 15.6% for the year ended December 31, 2019 due primarily to timing of booking versus travel as revenue benefited from travel early in the year ended December 31, 2020 before the COVID-19 pandemic, while gross bookings were negatively impacted by cancellations of bookings made in 2019.

Our international businesses accounted for approximately $6.0 billion of our total revenues for the year ended December 31, 2020, compared to $13.5 billion for the year ended December 31, 2019. Total revenues attributable to our international businesses for the year ended December 31, 2020 decreased by 55.6%, compared to the year ended December 31, 2019 (decreased on a constant-currency basis by approximately 55%). Total revenues attributable to our U.S. businesses decreased 49.0% for the year ended December 31, 2020 compared to the year ended December 31, 2019.

We rely on marketing channels to generate a significant amount of traffic to our websites. Marketing expenses consist primarily of the costs of: (1) search engine keyword purchases; (2) referrals from meta-search and travel research websites; (3) affiliate programs; (4) offline and online brand marketing; and (5) other performance-based marketing and incentives. For the year ended December 31, 2020, our marketing expense declined significantly due to reduced travel demand as a result of the COVID-19 pandemic. We adjust our marketing spend based on our growth and profitability objectives, as well as the travel demand and expected ROIs in our marketing channels. Marketing expenses as a percentage of total revenues decreased for the year ended December 31, 2020, compared to the year ended December 31, 2019, primarily due to actions we took to reduce our brand and performance marketing spend in response to the reduced travel demand.

 

Sales and other expenses consist primarily of: (1) credit card and other payment processing fees associated with merchant transactions; (2) provisions for expected credit losses, primarily related to accommodation commission receivables and prepayments to certain customers; (3) fees paid to third parties that provide call center, website content translations and other services; (4) customer relations costs; and (5) customer chargeback provisions and fraud prevention expenses associated with merchant transactions. For the year ended December 31, 2020, sales and other expenses, which are substantially variable in nature, decreased compared to the year ended December 31, 2019, due primarily to decreases in expenses related to

 

Personnel expenses consist of compensation to our personnel, including salaries, stock-based compensation, bonuses, payroll taxes, and employee health and other benefits. Personnel expenses decreased during the year ended December 31, 2020, compared to the year ended December 31, 2019, primarily due to $126 million of government aid benefit and approximately $110 million of savings resulting from restructuring activities at all our brands, as well as a decrease in stock-based compensation expense and lower bonus accruals, both of which were impacted by reduced financial performance and reduced headcount as a result of the COVID-19 pandemic. Stock-based compensation expense was $233 million for the year ended December 31, 2020, compared to $308 million for the year ended December 31, 2019. Headcount decreased 23% year-over-year to approximately 20,300 as of December 31, 2020, compared to approximately 26,400 as of December 31, 2019, primarily due to restructuring actions and attrition, as well as a general temporary company-wide hiring freeze. Given the timing of our restructuring actions, the average quarter-end headcount for 2020 only decreased 6% compared to 2019.

General and administrative expenses consist primarily of: (1) occupancy and office expenses; (2) fees for outside professionals, including litigation expenses; (3) indirect taxes such as travel transaction taxes and digital services taxes; and (4) personnel-related expenses such as travel, relocation, recruiting and training expenses. General and administrative expenses decreased during the year ended December 31, 2020, compared to the year ended December 31, 2019, due to lower personnel-related expenses associated with a general company-wide freeze on non-essential travel and entertainment and employee hiring due to the COVID-19 pandemic, lower office and occupancy expenses due to employees working remotely, and lower professional service fees.

Information technology expenses consist primarily of: (1) software license and system maintenance fees; (2) outsourced data center and cloud computing costs; (3) payments to contractors; and (4) data communications and other expenses associated with operating our services. Information technology expenses increased during the year ended December 31, 2020, compared to the year ended December 31, 2019, due to increased software license fees related to cyber security and data privacy software, as well as increased outsourced data center costs.

 

Depreciation and amortization expenses consist of: (1) amortization of intangible assets with determinable lives; (2) depreciation of computer equipment; (3) amortization of internally-developed and purchased software; and (4) depreciation of leasehold improvements, furniture and fixtures and office equipment. Depreciation and amortization expenses decreased during the year ended December 31, 2020, compared to the year ended December 31, 2019, as a result of decreased depreciation of computer equipment, amortization of intangible assets and depreciation of leasehold improvements, partially offset by increased internally-developed software amortization expenses.

 

During the year ended December 31, 2020, we took restructuring actions at all our brands in response to the impact of the COVID-19 pandemic on our business, and as a result incurred restructuring charges amounting to $149 million. These restructuring charges are primarily related to employee severance and benefits (see Note 20 to the Consolidated Financial Statements).

 

During the year ended December 31, 2020, we recorded impairment charges to goodwill related to OpenTable and KAYAK, which are not tax-deductible, of $1.1 billion (see Note 11 to our Consolidated Financial Statements and Critical Accounting Policies and Estimates included in this Management's Discussion and Analysis of Financial Condition and Results of Operations).

 

Interest expense increased for the year ended December 31, 2020, compared to the year ended December 31, 2019, primarily due to interest expense attributable to our Senior Notes and Convertible Senior Notes issued in April 2020.

Interest and dividend income decreased for the year ended December 31, 2020, compared to the year ended December 31, 2019, primarily due to lower average invested balances and lower yields as well as increased usage of investments classified as cash equivalents.

Impairment of investment for the year ended December 31, 2020 related to our investment in Didi Chuxing (see Notes 5 and 6 to our Consolidated Financial Statements and Critical Accounting Policies and Estimates included in this Management's Discussion and Analysis of Financial Condition and Results of Operations for additional information).

 

Our 2020 effective tax rate differs from the U.S. federal statutory tax rate of 21%, primarily due to the non-deductible goodwill impairment charges related to OpenTable and KAYAK, U.S. federal tax associated with our 2020 international earnings, and an increase in unrecognized tax benefits, partially offset by the benefit of the Netherlands Innovation Box Tax (discussed below). Our 2019 effective tax rate differs from the U.S. federal statutory tax rate of 21%, primarily due to the benefit of the Netherlands Innovation Box Tax, partially offset by the effect of higher international tax rates and U.S. federal and state tax associated with our 2019 international earnings, resulting from the enactment of the Tax Act, as well as certain non-deductible expenses.

Our effective tax rate was higher for the year ended December 31, 2020, compared to the year ended December 31, 2019, primarily due to the non-deductible goodwill impairment charges related to OpenTable and KAYAK, an increase in U.S. federal tax associated with our 2020 international earnings, and an increase in unrecognized tax benefits.

The COVID-19 pandemic and the resulting economic conditions and government orders have resulted in a material decrease in consumer spending and an unprecedented decline in travel and restaurant activities and consumer demand for related services. Our financial results and prospects are almost entirely dependent on the sale of travel-related services.

The extent of the effects of the COVID-19 pandemic on our business, results of operations, cash flows and growth prospects is highly uncertain and will ultimately depend on future developments. These include, but are not limited to, the severity, extent and duration of the COVID-19 pandemic, including as a result of any new variants of COVID-19 and any resurgences of the pandemic, and its impact on the travel and restaurant industries and consumer spending more broadly. Even if economic and operating conditions for our business improve, we cannot predict the long-term effects of the pandemic on our business or the travel and restaurant industries as a whole. If the travel and restaurant industries are fundamentally changed by the COVID-19 pandemic in ways that are detrimental to our operating model, our business may continue to be adversely affected even as the broader global economy recovers.

During the year ended December 31, 2020, we realized $2.2 billion in cash from sales and maturities of our investments in government and corporate debt securities. In addition, we sold our entire investment in Trip.com Group ADSs, with a cost basis of $655 million for $525 million.

At December 31, 2020, we had a remaining transition tax liability of $1.0 billion as a result of the Tax Act, which included $923 million reported as "Long-term U.S. transition tax liability" and $90 million included in "Accrued expenses and other current liabilities" in the Consolidated Balance Sheet. This liability will be paid over the next six years. In accordance with the Tax Act, generally, future repatriation of our international cash will not be subject to a U.S. federal income tax liability as a dividend, but will be subject to U.S. state income taxes and international withholding taxes, which have been accrued by us.

French tax authorities conducted audits of Booking.com for the years 2003 through 2012 and years 2013 through 2015 and currently are conducting an audit for the years 2016 through 2018. In December 2015, the French tax authorities issued Booking.com assessments for unpaid income and value added taxes ("VAT") related to tax years 2006 through 2012 for approximately 356 million Euros ($403 million), the majority of which represents penalties and interest.  The assessments assert that Booking.com had a permanent establishment in France. In December 2019, the French tax authorities issued an additional assessment of 70 million Euros ($86 million), including interest and penalties, for the 2013 year asserting that Booking.com had taxable income attributable to a permanent establishment in France. The French tax authorities also have issued assessments totaling 39 million Euros ($48 million), including interest and penalties, for certain tax years between 2011

Beginning in 2014, Booking.com received several letters from the Netherlands Pension Fund for the Travel Industry (Reiswerk) (“BPF”) claiming that Booking.com is required to participate in the mandatory pension scheme of the BPF with retroactive effect to 1999, which has a higher contribution rate than the pension scheme in which Booking.com is currently participating. BPF instituted legal proceedings against Booking.com and in 2016 the District Court of Amsterdam rejected all of BPF’s claims. BPF appealed the decision to the Court of Appeal, and, in May 2019, the Court of Appeal also rejected all of BPF’s claims, in each case by ruling that Booking.com does not meet the definition of a travel intermediary for purposes of the mandatory pension scheme. BPF has appealed to the Netherlands Supreme Court. In October 2020, the Dutch Advocate General issued an opinion to the Supreme Court stating that the Dutch Advocate General believes the decision of the Court of Appeal to be incorrect based on her interpretation of the pension scheme requirements. We have submitted to the Supreme Court a response to the Advocate General's opinion. While we continue to believe that Booking.com is in compliance with its pension obligations and that the Dutch Supreme Court should uphold the ruling of the Court of Appeal, based on the significant influence the Dutch Advocate General’s opinion typically has on the Supreme Court, we have reevaluated the probability of a loss and believe it is probable that we have incurred a loss related to this matter. We expect the Dutch Supreme Court to rule in the first quarter of 2021. In the event the Supreme Court overturns the decision of the Court of Appeal and remands the case to a lower court, we intend to pursue a number of defenses in any subsequent proceedings and may ultimately prevail in whole or in part. We are not able to reasonably estimate a loss or a range of loss because the litigation is ongoing and there are significant factual and legal questions yet to be determined. As a result, as of December 31, 2020, we have not recorded a liability in connection with a potential adverse outcome to this litigation. However, if Booking.com were to ultimately lose and all of BPF’s claims were to be accepted (including with retroactive effect to 1999), we estimate that as of December 31, 2020, the maximum loss, not including any potential interest or penalties, would be approximately $290 million. Such estimated potential loss increases as Booking.com continues not to contribute to the BPF and depends on Booking.com’s applicable employee compensation after December 31, 2020.

For additional information related to the pension matter and our other contingent liabilities, see Note 16 to our Consolidated Financial Statements.

The following table represents our material contractual obligations and commercial commitments at December 31, 2020: 

At December 31, 2020, we did not have any off-balance sheet arrangements that have, or are reasonably likely to have, a material current or future effect on our financial condition, results of operations, liquidity, capital expenditures or capital resources.

We have exposure to several types of market risk: changes in interest rates, foreign currency exchange rates and equity prices.

We manage our exposure to interest rate risk and foreign currency risk through internally established policies and procedures and, when deemed appropriate, through the use of derivative financial instruments. We use foreign 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 adverse fluctuations in rates. We evaluate our exposure to market risk by assessing the anticipated near-term and long-term fluctuations in interest rates and foreign currency exchange rates. This evaluation includes the review of leading market indicators, discussions with financial analysts and investment bankers regarding current and future economic conditions and the review of market projections as to expected future rates. We utilize this information to determine our own investment strategies as well as to determine if the use of derivative financial instruments is appropriate to mitigate any potential future market exposure that we may face. Our policy does not allow speculation in derivative instruments for profit or execution of derivative instrument contracts for which there are no underlying exposures. We do not use financial instruments for trading purposes and are not a party to any leveraged derivatives. To the extent that changes in interest rates and foreign currency exchange rates affect general economic conditions, we would also be affected by such changes.

net assets of the Euro functional currency subsidiary, the amount of the Euro-denominated debt that is designated as a hedge and fluctuations in foreign currency exchange rates.

We enter into foreign currency forward contracts to hedge our exposure to the impact of movements in foreign currency exchange rates on our transactional balances denominated in currencies other than the functional currency. In periods prior to the second quarter of 2020, we also entered into foreign currency derivative contracts to hedge translation risks from short-term foreign currency exchange rate fluctuations for the Euro, British Pound Sterling and certain other currencies versus the U.S. Dollar. Since the first quarter of 2020, we have not entered into such derivative instruments as the impact of the COVID-19 pandemic on our operating results are highly uncertain. We will continue to evaluate the use of derivative instruments in the future. See Note 6 to our Consolidated Financial Statements for further information.
