The following discussion should be read in conjunction with our Consolidated
Financial Statements, including the notes to those statements, included
elsewhere in this Annual Report on Form 10-K, and the Section entitled "Special
Note Regarding Forward-Looking Statements" in this Annual Report on Form 10-K.
As discussed in more detail in the Section entitled "Special Note Regarding
Forward-Looking Statements," this discussion contains forward-looking
statements, which involve risks and uncertainties.  Our actual results may
differ materially from the results discussed in the forward-looking statements.
Factors that might cause those differences include those discussed in "Risk
Factors" and elsewhere in this Annual Report on Form 10-K.

We evaluate certain operating and financial measures on both an as-reported and
constant-currency basis. We calculate constant currency by converting our
current-year period financial results for transactions recorded in currencies
other than U.S. Dollars using the corresponding prior-year period monthly
average exchange rates rather than the current-year period monthly average
exchange rates.

Overview



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
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 cruise, flight, 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,
KAYAK, priceline, agoda, Rentalcars.com 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 are
increasing 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, restaurant reservations, tours and activities
reservations and other services, many of which are supported by our other
brands. Similarly, hotel reservations available through Booking.com are also
generally available through agoda and priceline. See Note 2 to the Consolidated
Financial Statements - Segment Reporting for information on our operating
segments.

Our results include FareHarbor and HotelsCombined since they were acquired in
April 2018 and November 2018, respectively. We refer to our company and all of
our subsidiaries and brands collectively as "Booking Holdings," the "Company,"
"we," "our" or "us."

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. In 2019, our
international business (the substantial majority of which is generated by
Booking.com) represented approximately 90% 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.

We derive substantially all of our revenues from enabling consumers to make
travel service reservations. We also earn revenues from credit card processing
rebates and customer processing fees, advertising services, restaurant
reservations and restaurant management services, and various other services,
such as travel-related insurance revenues.

Trends



The recent coronavirus outbreak has had a significant and negative impact on our
business during the first quarter of 2020, in particular in China and certain
other Asian markets, though concerns about the coronavirus are also negatively
impacting travel demand (and therefore our business) generally. In the more
affected markets like China, we have seen a significant increase in
cancellations and reduction in new bookings, and ADRs have also been negatively
affected. The ultimate impact of the outbreak on our business is impossible to
predict with certainty, and therefore the full extent to which the coronavirus
will impact our business and results of operations is unknown. However,
decreased travel demand resulting from the outbreak has had a negative impact,
and is likely to have a negative and material impact, on our business, growth
and results of operations. For more information, see Part I, Item 1A, Risk
Factors - "Declines or disruptions in the travel industry could adversely affect
our business and financial performance."

Over the last several years, we have experienced significant growth in our
accommodation reservation services. We believe this growth is the result of,
among other things, the broader shift of travel purchases from offline to
online, the widespread adoption of mobile devices and the growth of travel
overall. We also believe this growth is 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. These year-over-year growth rates have generally
decelerated. Given the size of our accommodation reservation business and the
general slowing growth rate of the online travel market discussed below, we
expect that our year-over-year growth rates will generally continue to
decelerate, though the rate of deceleration may fluctuate and there may be
periods of acceleration from time to time.

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.
Online travel growth rates have generally slowed in markets such as North
America and Europe where online activity is high and consumers have been
engaging in e-commerce transactions for many years, while online travel growth
rates remain relatively high in markets such as Asia-Pacific where incomes are
rising more quickly and the increased availability and use of mobile devices has
accelerated the growth of internet usage and travel e-commerce transactions.
Over the long-term, we expect online travel growth rates to slow as markets
continue to mature. However, we believe that the opportunity to continue to grow
our business exists for the markets in which we operate, including in both
mature and fast-growing markets. Further, we believe that this opportunity for
growth exists because we feel we provide significant value to travel service
providers, regardless of size or geography, due to our global reach and online
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.

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 2,580,000 properties on
its website at December 31, 2019, consisting of approximately 460,000 hotels,
motels and resorts and approximately 2,120,000 homes, apartments and other
unique places to stay, compared to approximately 2,180,000 properties (including
approximately 436,000 hotels, motels and resorts and approximately 1,744,000
homes, apartments, and other unique places to stay) at December 31, 2018.
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 growth rate of our accommodations may
vary in part as a result of removing accommodations from our platforms from time
to time. 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.

                                       37
--------------------------------------------------------------------------------

Further, to the extent these properties represent an increasing percentage of
the properties added to our platforms, we expect that our room nights growth
rate and property growth rate will continue to diverge over time (since each
such 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. We believe that
continuing to expand the number and variety of accommodations available through
our services, in particular Booking.com, will help us to continue to grow our
accommodation reservation business.

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." Although we expect our efforts to build the Connected Trip may 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." As this business continues to grow, we expect
these expenses to continue to increase, 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 and
integrating its hotel and restaurant meta-search products into its Google Maps
app, as well as Google Travel, a planning tool which aggregates its flight,
hotel and packages products in one website. Our markets are also subject to
rapidly changing conditions, including technological developments, consumer
behavior changes, regulatory changes and travel service provider consolidation.
We expect these trends to continue. For example, we have experienced a
significant shift of both direct and indirect business to mobile platforms and
our advertising partners are also seeing a rapid shift of traffic to mobile
platforms. Advertising and distribution opportunities may be more limited on
mobile devices given their smaller screen sizes. In addition, the revenue 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
accommodation average daily rates ("ADRs") and are not made as far in advance.
For more detail regarding the competitive trends and risks we face, see Part I,
Item 1, Business - "Competition," Part I, Item 1A, Risk Factors - "Intense
competition could reduce our market share and harm our financial performance."
and "Consumer adoption and use of mobile devices creates challenges and may
enable device companies such as Google and Apple to compete directly with us."
and "We may not be able to keep up with rapid technological or other market
changes."
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

                                       38
--------------------------------------------------------------------------------

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 observed a trend of declining constant-currency accommodation ADRs,
which we expect to continue, though the rate of decline may fluctuate and there
may be periods of stable or increasing ADRs. We believe the trend of declining
ADRs is 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 resulting from competitive conditions,
weakening economic conditions or changes in travel patterns. 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.

We have established widely used and recognized e-commerce brands through
marketing and promotional campaigns. Historically our performance marketing
expenses have increased significantly, however, more recently, we have
experienced more moderate growth rates, a trend we expect to continue. Our
performance 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. More recently, growth
of some of these channels has slowed. Performance marketing expenses were $4.4
billion, $4.4 billion and $4.2 billion for the years ended December 31, 2019,
2018 and 2017, respectively. We also invested $548 million, $509 million and
$435 million in brand marketing for the years ended December 31, 2019, 2018 and
2017, respectively, 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. We intend
to continue a strategy of promoting brand awareness through both online and
offline marketing efforts, including by expanding brand campaigns into
additional markets, which we expect will increase our brand marketing expenses
over time. We have observed increased brand marketing by other OTCs, meta-search
services and travel service providers, which may make our brand marketing
efforts more expensive and less effective.

Performance marketing efficiency, expressed as performance 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 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 performance
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.

We have observed a long-term trend of decreasing performance marketing returns
on investment ("ROIs"). More recently, we have observed periods of stable or
increasing ROIs, however, it is uncertain whether this trend will continue or if
ROIs will return to the prior trend of declining over time. We may from time to
time, as we did beginning in the third quarter of 2017 through the fourth
quarter of 2018, pursue a strategy of improving our performance marketing ROIs,
which could negatively impact growth and positively impact performance marketing
efficiency and profitability. When evaluating our performance marketing spend,
we consider several factors for each channel, such as the customer experience on
the advertising platform, the incrementality of the traffic we receive and the
anticipated repeat rate from a particular platform, as well as other factors.
The amount of business we obtain through each performance marketing channel is
impacted by numerous factors, including bidding decisions by us and our
competitors (including decisions to optimize performance marketing ROIs) and the
marketing efforts and success of those channels to attract consumers and
generate demand. See Part I, Item 1A, Risk Factors - "We rely on performance and
brand marketing channels to generate a significant amount of traffic to our
platforms and grow our business." and "Our business could be negatively affected
by changes in online search and meta-search algorithms and dynamics or
traffic-generating arrangements."

In recent years, we experienced significant increases in our cancellation rates,
which negatively affected our marketing efficiency and results of operations.
Beginning in the third quarter of 2018, our cancellation rates have generally
decreased, which has benefited our marketing efficiency and results of
operations. We believe that many factors influence cancellation rates, and it is
uncertain whether future cancellation rates will continue to decrease, stabilize
or return to their prior trend of generally increasing over time.

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


                                       39
--------------------------------------------------------------------------------

tariffs and reduced government spending, could impair consumer spending and
adversely affect travel demand. Further, political uncertainty, conditions or
events, such as the United Kingdom's decision to leave the European Union
("Brexit"), including uncertainty in the implementation of Brexit and other
political concerns can also negatively affect consumer spending and adversely
affect travel demand. At times, we have experienced volatility in transaction
growth rates, increased cancellation rates and weaker trends in ADRs across many
regions of the world, particularly in those countries that appear to be most
affected by economic and political uncertainties, which we believe are due at
least in part to these macro-economic conditions and concerns. For more detail,
see Part I, Item 1A, Risk Factors - "Declines or disruptions in the travel
industry could adversely affect our business and financial performance."
These and other macro-economic uncertainties, such as 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.
As noted earlier, our international business represents a substantial majority
of our financial results. Therefore, because we report our results in U.S.
Dollars, we face exposure to movements in foreign currency exchange rates as the
financial results and the financial condition of our international businesses
are translated from local currency (principally Euros and British Pounds
Sterling) into U.S. Dollars. As a result, both the absolute amounts of and
percentage changes in our foreign-currency-denominated net assets, gross
bookings, revenues, operating expenses and net income as expressed in U.S.
Dollars are affected by foreign currency exchange rate changes. Our
foreign-currency-denominated gross bookings, revenues, operating expenses and
net income as expressed in U.S. Dollars are lower for the year ended
December 31, 2019 than they would have been had foreign currency exchange rates
remained where they were for the year ended December 31, 2018.  For example,
total revenues from our international operations grew 4.1% for the year ended
December 31, 2019 as compared to the year ended December 31, 2018, but, without
the impact of changes in foreign currency exchange rates, grew year-over-year on
a constant-currency basis by approximately 8%. Since our expenses are generally
denominated in foreign currencies on a basis similar to our revenues, our
operating margins have not been significantly impacted by currency fluctuations.
Historically, the aggregate principal value of our Euro-denominated long-term
debt, and accrued interest thereon, provided a hedge against the impact of
foreign currency exchange rate fluctuations on the net assets of one of our Euro
functional currency subsidiaries. Beginning in the second quarter of 2019, we
have only designated certain portions of the aggregate principal value of our
Euro-denominated debt as a hedge, and as a result we have recognized foreign
currency transaction gains or losses. The foreign currency transaction gains or
losses on the Euro-denominated debt that is not designated as a hedging
instrument for accounting purposes are recognized in "Foreign currency
transactions and other" in the Consolidated Statement of Operations (see Note 12
to our Consolidated Financial Statements). For more information, see Part I,
Item 1A, Risk Factors - "We are exposed to fluctuations in foreign currency
exchange rates."
We generally enter 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, such derivative
instruments are short-term in nature and not designed to hedge against currency
fluctuations that could impact growth rates for our gross bookings or revenues
(see Note 6 to our Consolidated Financial Statements for additional information
on our derivative contracts).

Many taxing authorities are increasingly focused on ways to increase tax
revenues and have targeted large multinational technology companies in these
efforts.  As a result, many countries have implemented or are considering
adoption of a digital services tax that imposes a tax on revenue earned from
digital advertisements and the use of online platforms, even when there is no
physical presence in the jurisdiction.  Currently rates for this tax range from
2% to 7.5% of revenue deemed generated in the jurisdiction. The digital services
taxes currently in effect have negatively impacted our results of operations and
if many other countries pass similar legislation, the collective impact of all
of these measures could have a materially adverse impact on our results of
operations and cash flows. For more information, see Note 16 to our Consolidated
Financial Statements and Part I, Item 1A, Risk Factors - "We may have exposure
to additional tax liabilities."

Many national governments have conducted or are conducting investigations into
competitive practices within the online travel industry, and we may be involved
or affected by such investigations and their results. Some countries have
adopted or proposed legislation that could also affect business practices within
the online travel industry. For example, France, Italy, Belgium and Austria have
passed legislation prohibiting parity contract clauses in their entirety. Also,
a number of governments are investigating or conducting information-gathering
exercises with respect to compliance by OTCs with consumer protection laws,
including practices related to the display of search results and search ranking
algorithms, claims regarding discounts, disclosure of charges and availability,
and similar messaging. For more information on these investigations and their
potential effects on our business, see Note 16 to our Consolidated Financial
Statements and Part I, Item 1A, Risk Factors - "Our business is subject to
various competition, anti-trust, consumer protection and online commerce laws,

                                       40
--------------------------------------------------------------------------------

rules and regulations around the world, and as the size of our business grows, scrutiny of our business by legislators and regulators in these areas may intensify." In addition to the price parity and consumer protection investigations, from time to time national competition authorities, other governmental agencies, trade associations and private parties take legal actions, including commencing legal proceedings, that may affect our operations. In general, increased regulatory focus on online businesses, including online travel businesses like ours, could result in increased compliance costs or otherwise adversely affect our business.

Seasonality



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 are booked. As a result of this potential timing
difference between when we record marketing expense and when we recognize
associated revenue, we experience our highest levels of profitability in the
third quarter of the year, which is when we experience the highest levels of
accommodation check-ins for the year for our European and North American
businesses. The first quarter of the year is typically our lowest level of
profitability and may experience additional volatility in earnings growth rates
due to these seasonal timing factors. For our Asia-Pacific business, we
experience the highest level of accommodation check-ins in the fourth quarter.
As the relative growth rates for our businesses fluctuate, the quarterly
distribution of our operating results may vary.

For several years, we experienced an expansion of the booking window (the
average time between the making of a travel reservation and the travel), 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. 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.

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.  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.

Other Factors

We believe that our future success depends in large part on our ability to
continue to profitably grow our brands worldwide, and, over time, to offer other
travel and travel-related services. Factors beyond our control, such as oil
prices, stock market volatility, terrorist attacks, unusual or extreme weather
or natural disasters such as earthquakes, hurricanes, tsunamis, floods, fires,
droughts and volcanic eruptions, 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
travel-related accidents or increased focus on the environmental impact of
travel, can disrupt travel, limit the ability or willingness of travelers to
visit certain locations or otherwise result in declines in travel demand. These
kinds of events have negatively affected our business and results of operations
in the past and may do so again in the future. 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

                                       41
--------------------------------------------------------------------------------

partners, any of which can adversely affect our business and results of operations. See Part I, Item 1A, Risk Factors - "Declines or disruptions in the travel industry could adversely affect our business and financial performance."



We intend to continue to invest in marketing and promotion, technology and
personnel within parameters consistent with attempts to improve long-term
operating results, even if those expenditures create pressure on operating
margins. We have experienced pressure on operating margins as we invest 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. As the overall size of our
business has grown, the 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 competitors have more resources or more
established or diversified relationships with consumers than we do, 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. For example, because consumers often utilize other
online services more frequently than online travel services, 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. Our goal is to
grow revenue and achieve healthy operating margins in an effort to maintain
profitability. The uncertain and highly competitive environment in which we
operate makes the prediction of future results of operations difficult, and
accordingly, we may not be able to sustain revenue growth and profitability.

Critical Accounting Policies and Estimates



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:

•            Valuation of Goodwill and Other Long-Lived Assets. 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.



We review goodwill for impairment annually and whenever events or changes in
circumstances indicate the carrying amount of goodwill may not be recoverable. A
substantial portion of our intangible assets and goodwill relates to the
acquisitions of OpenTable and KAYAK. At September 30, 2019, we performed our
annual goodwill impairment testing and concluded that there was no impairment of
goodwill and that the fair values of our reporting units substantially exceeded
their respective carrying values at September 30, 2019. Since the annual
impairment test, there have been no events or changes in circumstances to
indicate a potential impairment to our goodwill.

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 our 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. We did not identify any
impairment indicators for our long-lived assets at December 31, 2019.

•            Income Taxes. We determine our tax expense based on our 

income and


             statutory tax rates applicable in the various jurisdictions in which
             we operate. Due to the complex nature of tax legislation and
             frequent changes with such associated legislation, significant
             judgment is required in computing our tax expense and

determining


             our tax positions. In December 2017, the U.S. government 

enacted the

U.S. Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act made
             significant changes to U.S. federal tax law, including a reduction
             in the U.S. federal statutory tax rate from 35% to 21%, effective
             January 1, 2018. The Tax Act imposed a one-time deemed

repatriation


             tax on accumulated unremitted international earnings, to be paid
             over eight years.



The Tax Act also introduced in 2018 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, and a base erosion and anti-abuse tax ("BEAT") aimed at
preventing the erosion of the U.S. tax base. We have adopted an accounting
policy to treat taxes on GILTI as period costs.

In December 2017, Staff Accounting Bulletin No. 118 ("SAB 118") was issued by
the Securities and Exchange Commission to address the application of U.S. GAAP
in situations when the registrant does not have all the necessary information
available, prepared or analyzed (including computations) in reasonable detail to
complete its accounting for the change in tax law. In accordance with SAB 118,
to the extent a registrant can reasonably estimate the effects of the Tax Act, a
provisional tax amount can be recorded, but must have been finalized prior to
December 22, 2018. In 2018, we completed our accounting for the income tax
effects of the Tax Act based on technical guidance issued by U.S. federal and
state tax authorities available at that time, which resulted in an income tax
benefit of $48 million. In 2019, as a result of additional technical guidance
issued by U.S. federal and state tax authorities, we recorded an additional
income tax benefit of $17 million to adjust our income tax expense relating to
the U.S federal one-time deemed repatriation liability, as well as U.S state
income taxes associated with the mandatory deemed repatriation.

We do not intend to indefinitely reinvest our international earnings that were subject to U.S. taxation pursuant to the mandatory deemed repatriation or subject to U.S. taxation as GILTI.



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. To date, we have been audited in several taxing jurisdictions
with no significant impact on our results of operations. Although we believe
that our tax filing positions comply with applicable laws, the final
determination of tax audits or tax disputes may be different from what is
reflected in our historical income tax provisions and accruals. Accordingly, we
may incur additional tax expense based upon our assessment of the
more-likely-than-not outcomes or we may adjust previously recorded tax expense
to reflect examination results. See Note 16 to our Consolidated Financial
Statements for further information.

Recent Accounting Pronouncements - See Note 2 to our Consolidated Financial Statements for details, which is incorporated into this Item 7 by reference thereto.

Results of Operations

Year Ended December 31, 2019 compared to Year Ended December 31, 2018



We evaluate certain operating and financial measures on both an as-reported and
constant-currency basis. We calculate constant currency by converting our
current-year period financial results for transactions recorded in currencies
other than U.S. Dollars using the corresponding prior-year period monthly
average exchange rates rather than the current-year period monthly average
exchange rates.

Operating and Statistical Metrics



Our financial results are driven by certain operating metrics that encompass the
booking and other business activity generated by our travel 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, 2019 and 2018 were as follows:
                      Year Ended December 31,
                           (in millions)
                           2019               2018    Increase
Room nights            845                     760       11.2 %
Rental car days         77                      73        4.6 %
Airline tickets          7                       7        3.7 %



Accommodation room night reservations increased by 11.2% for the year ended
December 31, 2019, compared to the year ended December 31, 2018, primarily due
to our investments in marketing channels, providing a continuously improving
consumer experience and improving the accommodation choices we offer consumers,
as well as the overall growth in the travel industry and the ongoing shift from
offline to online for travel bookings. The increase for the year ended
December 31, 2019, compared to the year ended December 31, 2018 was also
positively impacted by a decrease in cancellation rates.

Rental car day reservations increased by 4.6% for the year ended December 31,
2019, compared to the year ended December 31, 2018, due primarily to an increase
in rental car day reservations at Rentalcars.com as a result of the integration
with Booking.com.

Airline ticket reservations increased by 3.7% for the year ended December 31, 2019, compared to the year ended December 31, 2018, due to the growth of priceline's vacation packages product.



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, 2019 and 2018 were as follows (numbers may not total
due to rounding):

              Year Ended December 31,
                   (in millions)
                  2019              2018       Increase (decrease)
Agency   $      70,651            $ 73,919             (4.4 )%
Merchant        25,791              18,812             37.1  %
Total    $      96,443            $ 92,731              4.0  %



Gross bookings increased by 4.0% for the year ended December 31, 2019, compared
to the year ended December 31, 2018 (growth on a constant-currency basis was
approximately 8%), almost entirely due to growth of 11.2% in accommodation

                                       44
--------------------------------------------------------------------------------

room night reservations, partially offset by the negative impact of foreign
currency exchange rate fluctuations and a 2% decrease in accommodation ADRs on a
constant-currency basis for the year ended December 31, 2019, compared to the
year ended December 31, 2018. 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 4.4% for the year ended December 31, 2019, compared
to the year ended December 31, 2018, almost entirely due to a decrease in gross
bookings from agency accommodation room night reservations at Booking.com,
primarily resulting from the growth of its merchant accommodation reservation
services, as well as the aforementioned negative impact of foreign currency
exchange rate fluctuations.

Merchant gross bookings are derived from services where we facilitate payments
from travelers for the travel services provided. Merchant gross bookings
increased by 37.1% for the year ended December 31, 2019, compared to the year
ended December 31, 2018, almost entirely due to growth in gross bookings from
our merchant accommodation reservation services at Booking.com and agoda,
partially offset by the aforementioned negative impact of foreign currency
exchange rate fluctuations. Booking.com has been expanding its merchant
accommodation reservation services to, among other reasons, 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 its
in-destination activities businesses.

Revenues

Online travel reservation services

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:

• Agency. Agency revenues are derived from travel-related transactions

where we do not facilitate payments from travelers for the services

provided. Agency revenues consist almost entirely of travel reservation


          commissions. Substantially all of our agency revenue is from
          Booking.com agency accommodation reservations.



•         Merchant. Merchant revenues are derived from travel-related
          transactions where we facilitate payments from travelers for the
          services provided, generally at the time of booking. Merchant revenues
          include (1) travel reservation commissions and transaction net revenues
          (i.e., the amount charged to travelers less the amount owed to travel
          service providers) in connection with our merchant reservation

services; (2) credit card processing rebates and customer processing

fees; and (3) ancillary fees, including travel-related insurance

revenues and certain global distribution system ("GDS") reservation


          booking fees. Substantially all merchant revenues are derived from
          transactions where travelers book accommodation reservations or rental
          car reservations.


Advertising and other revenues



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.

                                    Year Ended December 31,
                                         (in millions)
                                        2019              2018       Increase (decrease)
Agency revenues                $      10,117            $ 10,480             (3.5 )%
Merchant revenues                      3,830               2,987             28.2  %
Advertising and other revenues         1,119               1,060              5.6  %
Total revenues                 $      15,066            $ 14,527              3.7  %




                                       45

--------------------------------------------------------------------------------

Total revenues for the year ended December 31, 2019, as compared to the year ended December 31, 2018, respectively, increased by 3.7% (growth on a constant-currency basis was approximately 7%). Substantially all of the year-over-year increase was related to revenues from our accommodation reservation services.



Agency revenues decreased by 3.5% for the year ended December 31, 2019, compared
to the year ended December 31, 2018, almost entirely due to decreased gross
bookings from agency accommodation room night reservations at Booking.com,
primarily resulting from the growth of its merchant accommodation reservation
services.

Merchant revenues increased by 28.2% for the year ended December 31, 2019, compared to the year ended December 31, 2018, primarily due to the increases in merchant accommodation reservation services.



Advertising and other revenues increased by 5.6% for the year ended December 31,
2019, compared to the year ended December 31, 2018, primarily due to the
inclusion of $67 million in revenue related to HotelsCombined for the year ended
December 31, 2019, compared to $4 million in revenue related to HotelsCombined
since its acquisition in November 2018 for the year ended December 31, 2018.

Total revenues as a percentage of gross bookings was 15.6% for the year ended December 31, 2019 as compared to 15.7% for the year ended December 31, 2018.



Our international businesses accounted for approximately $13.5 billion of our
total revenues for the year ended December 31, 2019, compared to $13.0 billion
for the year ended December 31, 2018. Total revenues attributable to our
international businesses for the year ended December 31, 2019 increased by 4.1%,
compared to the year ended December 31, 2018 (growth on a constant-currency
basis was approximately 8%). Total revenues attributable to our U.S. businesses
were relatively flat for the year ended December 31, 2019 compared to the year
ended December 31, 2018.

Operating Expenses

Performance marketing $     4,419       $     4,447              (0.6 )%
% of Total revenues          29.3 %            30.6 %
Brand marketing       $       548       $       509               7.5  %
% of Total revenues           3.6 %             3.5 %



We rely on performance marketing channels to generate a significant amount of
traffic to our websites. Performance 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; and (4) other
performance-based marketing and incentives. For the year ended December 31,
2019, our performance marketing expense growth rate was reduced by foreign
currency exchange rate fluctuations and slowing growth in performance marketing
channels. We adjust our performance marketing spend based on our growth and
profitability objectives and the expected ROIs in our performance marketing
channels. Performance marketing expense as a percentage of total revenues
decreased for the year ended December 31, 2019, compared to the year ended
December 31, 2018, due to changes in the share of traffic by channel, primarily
related to an increase in the share of direct traffic, and increased performance
marketing ROIs.

Brand marketing expenses consist primarily of television advertising and online
video and display advertising (including the airing of our television
advertising online), as well as other marketing spend such as public relations
and sponsorships. For the year ended December 31, 2019, brand marketing expenses
increased by 7.5% compared to the year ended December 31, 2018, primarily due to
increased brand marketing expenses at Booking.com in the first half of 2019 in
order to increase brand awareness and grow the number of customers that come
directly to the Booking.com platforms.

Sales and Other Expenses

                            Year Ended December 31,
                                 (in millions)

% of Total revenues              6.3 %           5.7 %



Sales and other expenses consist primarily of: (1) credit card and other payment
processing fees associated with merchant transactions; (2) fees paid to third
parties that provide call center, website content translations and other
services; (3) customer chargeback provisions and fraud prevention expenses
associated with merchant transactions; (4) customer relations costs; and (5)
provisions for bad debt, primarily related to agency accommodation commission
receivables. For the year ended December 31, 2019, sales and other expenses,
which are substantially variable in nature, increased compared to the year ended
December 31, 2018 due primarily to increases in our merchant transaction
volumes, partially offset by lower chargeback expense and lower bad debt
provisions.

Personnel

                        Year Ended December 31,
                             (in millions)

% of Total revenues        14.9 %            14.1 %



Personnel expenses consist of compensation to our personnel, including salaries,
stock-based compensation, bonuses, payroll taxes, and employee health and other
benefits. Personnel expenses increased during the year ended December 31, 2019,
compared to the year ended December 31, 2018, primarily due to an increase in
aggregate salaries of $132 million related to headcount growth to support our
businesses, partially offset by lower bonus expenses. The increase in personnel
expenses was also due to an accrual of $61 million recorded in 2019 to correct
an immaterial error related to the nonpayment in prior periods of a wage-related
tax under Netherlands' law on compensation paid to certain highly-compensated
former employees in the year of their separation from employment with
Booking.com. Stock-based compensation expense was $308 million for the year
ended December 31, 2019, compared to $317 million for the year ended
December 31, 2018. Headcount increased, primarily at agoda and Booking.com, in
the areas of customer service and information technology to support transaction
growth and various business initiatives, such as alternative accommodations,
marketing, payments and in-destination experiences.

General and Administrative

                              Year Ended December 31,
                                   (in millions)

% of Total revenues                5.3 %           4.8 %



General and administrative expenses consist primarily of: (1) occupancy and
office expenses; (2) personnel-related expenses such as travel, relocation,
recruiting and training expenses; (3) fees for outside professionals, including
litigation expenses; and (4) indirect taxes such as travel transaction taxes and
digital services taxes. General and administrative expenses increased during the
year ended December 31, 2019, compared to the year ended December 31, 2018, due
to increased professional fees, increased indirect taxes including $36 million
related to French digital service taxes, higher occupancy and office expenses
and personnel-related expenses associated with increased headcount and outside
consultants to support the expansion of our international businesses.

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, 2019, compared to the year ended
December 31, 2018, due to increased outsourced data center and cloud computing
costs to support the growth in our businesses, software fees and payments to
contractors.

Depreciation and Amortization



                                 Year Ended December 31,
                                      (in millions)
                                   2019             2018      Increase

Depreciation and amortization $ 469 $ 426 10.0 % % of Total revenues

                   3.1 %           2.9 %



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 increased during the year
ended December 31, 2019, compared to the year ended December 31, 2018, primarily
as a result of increases of $22 million in data center equipment depreciation
expenses and $18 million of internally-developed software amortization expenses
due to higher capital expenditures and capitalized software development costs to
support growth and geographic expansion.

Interest income decreased for the year ended December 31, 2019, compared to the
year ended December 31, 2018, primarily due to lower average invested balances
of marketable securities and lower yields as well as increased usage of
investments classified as cash equivalents.

Net unrealized gains (losses) on marketable equity securities for the year ended December 31, 2019 and December 31, 2018 principally related to our equity investments in Trip.com Group and Meituan Dianping (see Note 5 to our Consolidated Financial Statements for further information).



Foreign currency transactions and other includes foreign currency gains or
losses on derivative contracts, foreign currency transaction gains or losses,
including costs related to foreign currency transactions, and net realized gains
or losses on investments and other income or expense. Foreign currency
transactions and other includes foreign currency losses on derivative contracts
of $19 million and $44 million and foreign currency transaction losses of $13
million and $9 million for

                                       48

the years ended December 31, 2019 and 2018, respectively. In addition, foreign
currency transactions and other includes a net realized gain of $11 million for
the year ended December 31, 2019 from sales of investments in debt securities.

Income Taxes

                                     Year Ended December 31,
                                          (in millions)
                                       2019             2018       Increase
Income tax expense                $      1,093       $     837        30.6 %

% of Earnings before income taxes 18.3 % 17.3 %





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
(discussed below), partially offset by the effect of higher international tax
rates and U.S. federal and state tax associated with our current year
international earnings, resulting from the enactment of the Tax Act, as well as
certain non-deductible expenses. Our 2018 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 and the $46 million benefit resulting from the
adjustment to our 2017 provisional income tax expense due to our completion of
the accounting for the income tax effects of the Tax Act, partially offset by
the effect of higher international tax rates and U.S. federal and state tax
associated with our 2018 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, 2019, compared
to the year ended December 31, 2018, primarily as a result of (1) higher U.S.
gains from equity securities that contributed to a lower international
jurisdictional earnings mix, which lessened the impact of the benefit of the
Netherlands Innovation Box Tax, and (2) the effect of the higher tax benefit
recorded during the year ended December 31, 2018 to adjust our 2017 provisional
income tax expense related to the Tax Act. These increases in our effective tax
rate were partially offset by higher U.S. federal tax credits, lower U.S.
federal and state tax associated with our current year international earnings,
and certain lower non-deductible expenses.

A portion of Booking.com's earnings during the years ended December 31, 2019 and
2018 qualified for Innovation Box Tax treatment under Dutch tax law, which had a
significant beneficial impact on our effective tax rates for those periods. In
2019, the Dutch government approved a reduction in its corporate income tax rate
from 25% to 21.7%, effective in 2021. Furthermore, the Dutch government has
proposed an increase in the Innovation Box Tax rate from 7% to 9%, which, if
enacted, could be effective beginning in 2021. While we expect Booking.com to
continue to qualify for Innovation Box Tax treatment with respect to a portion
of its earnings for the foreseeable future, the loss of the Innovation Box Tax
benefit, whether due to a change in tax law or a determination by the Dutch
government that Booking.com's activities are not innovative or for any other
reason, would substantially increase our effective tax rate and adversely impact
our results of operations and cash flows. See Part I, Item 1A, Risk Factors -
"We may not be able to maintain our 'Innovation Box Tax' benefit."

Results of Operations

Year Ended December 31, 2018 compared to Year Ended December 31, 2017



For a comparison of our results of operations for the fiscal years ended
December 31, 2018 and 2017, see   Item 7. Management's Discussion and Analysis
of Financial Condition and Results of Operations  , of our Annual Report on Form
10-K for the fiscal year ended December 31, 2018, filed with the SEC on February

--------------------------------------------------------------------------------

Liquidity and Capital Resources



At December 31, 2019, we had $11.8 billion in cash, cash equivalents and
short-term and long-term investments, of which approximately $4.7 billion is
held by our international subsidiaries and is denominated primarily in U.S.
Dollars, Euros and, to a lesser extent, British Pounds Sterling and other
currencies. Cash equivalents and short-term and long-term investments are
principally comprised of U.S. and international corporate bonds, U.S. and
international government securities, money market funds, time deposits and
certificates of deposit, convertible debt securities and American Depositary
Shares ("ADSs") of Trip.com Group, Meituan Dianping equity securities and our
investments in private companies. In August 2019, $500 million of Trip.com Group
convertible notes were repaid on maturity. See Notes 5 and 6 to our Consolidated
Financial Statements for further information.

In the first quarter of 2020 and 2019, we made prepayments of $717 million and
$774 million, respectively, which represent a portion of our Dutch income tax
liability, to earn prepayment discounts.

At December 31, 2019, we had a remaining transition tax liability of $1.1
billion as a result of the Tax Act, which included $1.0 billion reported as
"Long-term U.S. transition tax liability" and $53 million included in "Accrued
expenses and other current liabilities" in the Consolidated Balance Sheet. This
liability will be paid over the next seven years. Generally, in accordance with
the Tax Act, 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. See Note 15 to our Consolidated Financial Statements for further
information.

In August 2019, we entered into a $2.0 billion five-year unsecured revolving
credit facility with a group of lenders. The revolving credit facility provides
for the issuance of up to $80 million of letters of credit as well as borrowings
of up to $100 million on same-day notice, referred to as swingline loans. The
proceeds of loans made under the facility can be used for working capital and
general corporate purposes, including acquisitions, share repurchases and debt
repayments. At December 31, 2019, there were no borrowings outstanding and $5
million of letters of credit issued under the facility. Upon entering into the
new revolving credit facility in August 2019, we terminated the $2.0 billion
five-year revolving credit facility entered into in June 2015. We made several
short-term borrowings under this prior revolving credit facility in the first
half of 2019 totaling $400 million, all of which were repaid prior to June 30,
2019. See Note 12 to our Consolidated Financial Statements for further
information.

Our Convertible Senior Notes due June 2020 (the "2020 Notes") are reported as
current liabilities in the Consolidated Balance Sheet at December 31, 2019. The
holders will have the right to convert all or any portion of the 2020 Notes
starting on March 15, 2020 regardless of our stock price (see Note 12 to the
Consolidated Financial Statements).

During the year ended December 31, 2019, we repurchased 4,444,944 shares of our
common stock for an aggregate cost of $8.2 billion. At December 31, 2019, we had
a remaining aggregate amount of $11.5 billion authorized by our Board of
Directors to repurchase our common stock. We have continued to make repurchases
of our common stock in the first quarter of 2020 and may continue to make
additional repurchases of our common stock from time to time, depending on
prevailing market conditions, alternate uses of capital and other factors.

In September 2016, we signed a turnkey agreement to construct an office building
for Booking.com's future headquarters in the Netherlands for 270 million Euros.
Upon signing this agreement, we paid 43 million Euros for the acquired land-use
rights. In addition, since signing the turnkey agreement we have made several
progress payments principally related to the construction of the building. At
December 31, 2019, we have a remaining obligation of 109 million Euros ($123
million) related to the building construction, which will be paid through
mid-2022, when we anticipate construction will be complete. In addition to the
turnkey agreement, we have a remaining obligation at December 31, 2019 to pay 71
million Euros ($80 million) over the remaining term of the acquired land lease.
We will also make additional capital expenditures to fit out and furnish the
office space. See Note 16 to our Consolidated Financial Statements.

Cash Flow Analysis



Net cash provided by operating activities decreased by $473 million, for the
year ended December 31, 2019, compared to the year ended December 31, 2018,
primarily due to the payment of $403 million in 2019 to French tax authorities
to preserve our right in order to contest certain tax assessments in court (see
Note 16 to our Consolidated Financial Statements).

Net cash provided by operating activities for the year ended December 31, 2019,
was $4.9 billion, resulting from net income of $4.9 billion and a favorable
impact from adjustments for non-cash items of $541 million, partially offset by
an unfavorable net change in working capital and long-term assets and
liabilities of $541 million. Non-cash items were

                                       50
--------------------------------------------------------------------------------

principally associated with net unrealized gains on marketable equity
securities, depreciation and amortization, stock-based compensation expense,
operating lease amortization and the provision for uncollectible accounts and
chargebacks. The changes in working capital for the year ended December 31,
2019, reflecting the increase in business volume and growth in Booking.com's
merchant transactions, were primarily related to a $480 million increase in
accounts payable, accrued expenses and other current liabilities, offset by a
$323 million increase in accounts receivable and $263 million increase in
prepaid expenses and other current assets. Net change in other long-term assets
and liabilities of $399 million was primarily due to the increase in other
long-term assets related to the payment of $403 million to French tax
authorities in order to preserve our right to contest the assessments in court
(see Note 16 to our Consolidated Financial Statements).

Net cash provided by operating activities for the year ended December 31, 2018
was $5.3 billion, resulting from net income of $4.0 billion, a favorable impact
from adjustments for non-cash items of $1.2 billion and a favorable net change
in working capital and long-term assets and liabilities of $125 million.
Non-cash items were principally associated with net unrealized losses on
marketable equity securities, stock-based compensation expense, depreciation and
amortization and the provision for uncollectible accounts and chargebacks. The
changes in working capital for the year ended December 31, 2018, reflecting the
increase in business volume and growth in Booking.com's merchant transactions,
were primarily related to a $635 million increase in accounts payable, accrued
expenses and other current liabilities, offset by a $319 million increase in
accounts receivable and a $201 million increase in prepaid expenses and other
current assets.

Net cash provided by investing activities for the year ended December 31, 2019
was $7.1 billion, principally resulting from the proceeds from sales and
maturities of investments of $8.1 billion, net of purchases of $0.7 billion. Net
cash provided by investing activities for the year ended December 31, 2018 was
$2.2 billion, principally resulting from the proceeds from sales and maturities
of investments of $5.6 billion, net of purchases of $2.7 billion, partially
offset by acquisitions and other investments, net of cash acquired, of $273
million. Cash invested in the purchase of property and equipment was $368
million and $442 million for the years ended December 31, 2019 and 2018,
respectively, which primarily related to additional data center capacity and new
offices to support growth and geographic expansion related to our Booking.com
and agoda brands. Cash invested in the purchase of property and equipment for
the years ended December 31, 2019 and 2018 includes payments of $51 million and
$78 million, respectively, related to the turnkey agreement for constructing
Booking.com's future headquarters.

Net cash used in financing activities for the year ended December 31, 2019 was
$8.2 billion, almost entirely resulting from payments for the repurchase of
common stock. Net cash used in financing activities for the year ended
December 31, 2018 was $7.4 billion, which primarily consisted of payments for
the repurchase of common stock of $6.0 billion and payments for the conversion
of senior notes of $1.5 billion.

For a discussion of our liquidity and capital resources as of and our cash flow activities for the fiscal year ended December 31, 2017, see Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations , of our Annual Report on Form 10-K for the fiscal year ended December 31, 2018, filed with the SEC on February 27, 2019.

Contingencies



French tax authorities conducted an audit of Booking.com for the years 2003
through 2012 and are conducting audits for the years 2013 through 2018. They are
asserting that Booking.com has a permanent establishment in France and are
seeking to recover what they claim are unpaid income and value-added taxes. In
December 2015, the French tax authorities issued Booking.com assessments related
to tax years 2003 through 2012 for approximately 356 million Euros, the majority
of which represents penalties and interest.  As a result of a formal demand from
the French tax authorities for payment of the amounts assessed for the years
2003 through 2012, in January 2019, we paid the assessments of approximately 356
million Euros ($403 million) in order to preserve our right to contest those
assessments in court. The payment, which is included in "Other assets" in the
Consolidated Balance Sheet at December 31, 2019, does not constitute an
admission that we owe the taxes and will be refunded (with interest) to us to
the extent we prevail. If we are unable to resolve the matter with the French
tax authorities, we plan to challenge the assessments in the French courts. In
December 2019, the French tax authorities issued an additional assessment of 70
million Euros ($79 million), including interest and penalties, for the 2013 year
asserting that Booking.com has taxable income in France attributable to a
permanent establishment in France. Furthermore, the French tax authorities have
issued assessments totaling 39 million Euros ($44 million), including interest
and penalties, for certain tax years between 2011 and 2015 on Booking.com's
French subsidiary asserting that the subsidiary did not receive sufficient
compensation for the services it rendered to Booking.com in the Netherlands. We
have not recorded a liability in connection with any of the French tax
assessments as we believe that Booking.com has been, and continues to be, in
compliance with French tax law, and we are contesting the assessments.
Additional assessments could result when the French tax authorities complete the
outstanding audits. See Note 16 to our Consolidated Financial Statements and
Part I, Item 1A, Risk Factors - "We may have exposure to additional tax
liabilities."

Contractual Obligations and Commercial Commitments

The following table represents our material contractual obligations and commercial commitments at December 31, 2019:

(1) Includes the land lease for Booking.com's future headquarters. See Notes 10

and 16 to our Consolidated Financial Statements for further details.

(2) See Note 16 to our Consolidated Financial Statements for further details.

(3) Represents significant noncancellable contractual obligations individually

greater than $10 million. The obligations are primarily related to

sponsorship and cloud hosting arrangements.

(4) Represents the aggregate principal amount of our senior notes outstanding at

December 31, 2019 and cumulative interest to maturity of $928 million.

Convertible debt does not reflect the market value in excess of the

outstanding principal amount because we can settle the conversion premium

amount in cash or shares of common stock at our option. See Note 12 to our

Consolidated Financial Statements.

(5) Standby letters of credit and bank guarantees issued on behalf of the Company

at December 31, 2019 are primarily related to payment guarantees to

third-party payment processors (see Notes 12 and 16).

(6) Represents commitment fees on undrawn balances available under the revolving

credit facility and fees on outstanding letters of credit at December 31,

2019.

(7) We reported "Other long-term liabilities" of $104 million in the Consolidated

Balance Sheet at December 31, 2019, the majority of which relates to

unrecognized tax benefits of $51 million (see Note 15 to our Consolidated

Financial Statements). We have excluded these long-term liabilities from the

contractual obligations table above as a variety of factors could affect the

timing of payments for the liabilities; therefore, we cannot reasonably

estimate the timing of such payments. We believe that these matters will

likely not be resolved in the next twelve months and, accordingly, we have

classified the estimated liability as non-current in the Consolidated Balance


    Sheet.



In 2018, we entered into an agreement to sign a future lease related to
approximately 222,000 square feet of office space in the city of Manchester in
the United Kingdom for the future headquarters of Rentalcars.com. Our obligation
to execute the lease is conditional upon the lessor completing certain
activities, which are expected to be completed in 2021. If these activities are
completed, the lease will commence for a term of approximately 13 years and we
will have a lease obligation of approximately 65 million British Pounds Sterling
($86 million), excluding lease incentives. We will also make capital
expenditures to fit out and furnish the office space. The obligation is not
included in the table of contractual obligations presented above.

We believe that our existing cash balances and liquid resources will be
sufficient to fund our operating activities, capital expenditures and other
obligations through at least the next twelve months. However, if during that
period or thereafter, we are not successful in generating sufficient cash flow
from operations or in raising additional capital when required in sufficient
amounts and on terms acceptable to us, we may be required to reduce our planned
capital expenditures and scale back the scope of our business plans, either of
which could have a material adverse effect on our future financial condition or
results of operations. If additional funds were raised through the issuance of
equity securities, the percentage ownership of our then current stockholders
would be diluted. We may not generate sufficient cash flow from operations in
the future, revenue growth

or sustained profitability may not be realized, and future borrowings or equity
sales may not be available in amounts sufficient to make anticipated capital
expenditures, finance our strategies or repay our indebtedness.

Off-Balance Sheet Arrangements



At December 31, 2019, we did not have any off-balance sheet arrangements that
have, or are reasonably likely to have, a current or future effect on our
financial condition, results of operations, liquidity, capital expenditures or
capital resources.
