Overview

Airbnb is a community based on connection and belonging-a community that was
born in 2007 when two hosts welcomed three guests to their San Francisco home,
and has since grown to 4 million hosts who have welcomed over 800 million guest
arrivals to approximately 100,000 cities in almost every country and region
across the globe. Hosts on Airbnb are everyday people who share their worlds to
provide guests with the feeling of connection and being at home. Airbnb has five
stakeholders and is designed with all of them in mind. Along with employees and
shareholders, we serve hosts, guests, and the communities in which they live. We
intend to make long-term decisions considering all of our stakeholders because
their collective success is key for our business to thrive.

We operate a global marketplace, where hosts offer guests stays and experiences
on our platform. Our business model relies on the success of hosts and guests
who join our community and generate consistent bookings over time. As hosts
become more successful on our platform and as guests return over time, we
benefit from the recurring activity of our community.
Impact of COVID-19 on our Business

For almost a year, many travelers have avoided traveling long distance because
of COVID-19 concerns, quarantines, and travel restrictions.
During the first quarter of 2021, we continued to face lower demand for long
distance travel and overall depressed Nights and Experiences Booked compared to
2019. While the outlook for the entire year is unclear, we are seeing signs of
travel recovery as the rate of vaccinations increases and quarantine
requirements and travel restrictions are lifted. For example, during the first
quarter of 2021, we saw an increase in Nights and Experiences Booked compared to
the same prior year period. According to a survey conducted by us earlier this
year, more than half of the people surveyed said they either already booked
travel, are currently planning to travel, or expect to travel in 2021. We are
preparing for when travel rebounds as there will be a collective desire for two
things: travel and human connection.

Prior to the outbreak, we had seen strong year-over-year growth in Nights and
Experiences Booked during the first three weeks of 2020. However, by the end of
March 2020, COVID-19 had spread across the world and been declared a global
pandemic. In order to protect our business from these near-term market
disruptions and the prospect of a prolonged business impact, we raised
$2.0 billion in the form of term loans in April 2020 and took action to
dramatically reduce our operating expenses, which included suspending
substantially all discretionary marketing program spend, reducing full-time
employee headcount by approximately 25%, and suspending all facilities
build-outs and significantly reducing capital expenditures. These incremental
funds and our rapid management of expenses, in addition to our existing cash
position, helped us to prudently manage our business through the effects of the
COVID-19 pandemic during 2020.

While COVID-19 still plagues the world, for the three months ended March 31,
2021, GBV and revenue were $10.3 billion and $886.9 million, respectively, which
were both higher compared to the same prior year period. These improvements were
driven by fewer cancellations and stronger results in North America, in
particular with resilience in domestic and short-distance travel, with more
people gravitating toward Airbnb stays within driving distance of their homes.
Buoyed by the increased confidence in travel and overall market in the first few
months of 2021 compared to the same prior year period when the global pandemic
was announced, we were able to issue $2.0 billion aggregate principal amount of
0% convertible senior notes due 2026 in March 2021. In connection with the
pricing of the notes, we also entered into privately negotiated capped call
transactions. The net proceeds from issuance of the notes, together with
existing cash, were used to repay the remaining principal amount outstanding
under the term loans entered into in April 2020.

We believe that the recovery in GBV that we experienced in the first quarter of
2021 was attributable to the renewed ability and willingness for guests to
travel, fewer cancellations, the resilience of our hosts, and relative strength
of our business model. While we witnessed the way people travel change as a
result of COVID-19, the adaptability of our business suggests that we are
well-positioned to serve this dynamic market as it continues to evolve and
recover.

The extent and duration of the impact of the COVID-19 pandemic over the longer
term remain uncertain and dependent on future developments that cannot be
accurately predicted at this time, such as the severity and transmission rate of
COVID-19, the extent and effectiveness of containment actions taken, including
mobility restrictions, the timing, availability, and effectiveness of vaccines,
and the impact of these and other factors on travel behavior in general, and on
our business in particular.
Key Business Metrics and Non-GAAP Financial Measures
We track the following key business metrics and financial measures that are not
calculated and presented in accordance with GAAP ("non-GAAP financial measures")
to evaluate our performance, identify trends, formulate financial projections,
and make strategic decisions. Accordingly, we believe that these key business
metrics and non-GAAP financial measures provide useful information to investors
and others in understanding and evaluating our results of operations in the same
manner as our management team. These key business metrics
                                       25
--------------------------------------------------------------------------------


and non-GAAP financial measures are presented for supplemental informational
purposes only, should not be considered a substitute for financial information
presented in accordance with GAAP, and may be different from similarly titled
metrics or measures presented by other companies. A reconciliation of each
non-GAAP financial measure to the most directly comparable financial measure
stated in accordance with GAAP is provided under the subsection titled "-
Adjusted EBITDA" and "- Free Cash Flow" below.
Key Business Metrics

We review the following key business metrics to measure our performance,
identify trends, formulate financial projections, and make strategic decisions.
We are not aware of any uniform standards for calculating these key metrics,
which may hinder comparability with other companies that may calculate similarly
titled metrics in a different way.

Nights and Experiences Booked
Nights and Experiences Booked is a key measure of the scale of our platform,
which in turn drives our financial performance. Nights and Experiences Booked on
our platform in a period represents the sum of the total number of nights booked
for stays and the total number of seats booked for experiences, net of
cancellations and alterations that occurred in that period. For example, a
booking made on February 15 would be reflected in Nights and Experiences Booked
for our quarter ended March 31. If, in the example, the booking were canceled on
May 15, Nights and Experiences Booked would be reduced by the cancellation for
our quarter ended June 30. A night can include one or more guests and can be for
a listing with one or more bedrooms. A seat is booked for each participant in an
experience. Substantially all of the bookings on our platform to date have come
from nights. We believe Nights and Experiences Booked is a key business metric
to help investors and others understand and evaluate our results of operations
in the same manner as our management team, as it represents a single unit of
transaction on our platform.

In the first quarter of 2021, we had 64.4 million Nights and Experiences Booked,
a 13% increase from 57.1 million Nights and Experiences Booked in the same prior
year period. Nights and Experiences Booked grows as we attract new hosts and
guests to our platform and as repeat guests increase their activity on our
platform. Our Nights and Experiences Booked increased from prior levels
primarily as a result of continued increase in domestic travel on our platform.
This improvement was largely driven by stronger results in North America, in
particular with resilience in domestic and short-distance travel, with more
people gravitating toward Airbnb stays within driving distance of their homes.

Gross Booking Value
GBV represents the dollar value of bookings on our platform in a period and is
inclusive of host earnings, service fees, cleaning fees, and taxes, net of
cancellations and alterations that occurred during that period. The timing of
recording GBV and any related cancellations is similar to that described in the
subsection titled "- Key Business Metrics and Non-GAAP Financial Measures -
Nights and Experiences Booked" above. Revenue from the booking is recognized
upon check-in; accordingly, GBV is a leading indicator of revenue. The entire
amount of a booking is reflected in GBV during the quarter in which booking
occurs, whether the guest pays the entire amount of the booking upfront or
elects to use our Pay Less Upfront program.

Growth in GBV reflects our ability to attract and retain hosts and guests and
reflects growth in Nights and Experiences Booked. In the first quarter of 2021,
our GBV was $10.3 billion, a 52% increase from $6.8 billion in the same prior
year period. The increase in our GBV was primarily due to continued increase in
domestic travel on our platform. Similar to Nights and Experiences Booked, this
improvement was largely driven by stronger results in North America, in
particular with resilience in domestic and short-distance travel, with more
people gravitating toward Airbnb stays within driving distance of their homes.
On a constant currency basis, the increase in GBV was 48%.

Non-GAAP Financial Measures



In addition to our results determined in accordance with GAAP, we believe the
following non-GAAP measures are useful in evaluating our operating performance.
We use the following non-GAAP financial information, collectively, to evaluate
our ongoing operations and for internal planning and forecasting purposes. We
believe that non-GAAP financial information, when taken collectively, may be
helpful to investors because it provides consistency and comparability with past
financial performance, and assists in comparisons with other companies, some of
which use similar non-GAAP financial information to supplement their GAAP
results. The non-GAAP financial information is presented for supplemental
informational purposes only, should not be considered a substitute for financial
information presented in accordance with GAAP, and may be different from
similarly titled non-GAAP measures used by other companies. A reconciliation of
each non-GAAP financial measure to the most directly comparable financial
measure stated in accordance with GAAP is provided below. Investors are
encouraged to review the related GAAP financial measures and the reconciliation
of these non-GAAP financial measures to their most directly comparable GAAP
financial measures.

The following table summarizes our non-GAAP financial measures, along with the most directly comparable GAAP measure, for each period presented below.

Adjusted EBITDA                                                  $     (334,271)        $    (58,638)

Net cash provided by (used in) operating activities              $     (569,830)        $    494,368
Free Cash Flow                                                   $     (585,497)        $    486,662


Adjusted EBITDA

We define Adjusted EBITDA as net income or loss adjusted for (i) provision for
(benefit from) income taxes; (ii) interest income, interest expense, and other
income (expense), net; (iii) depreciation and amortization; (iv) stock-based
compensation expense and stock-settlement obligations related to the IPO; (v)
acquisition-related impacts consisting of gains (losses) recognized on changes
in the fair value of contingent consideration arrangements; (vi) net changes to
the reserves for lodging taxes for which management believes it is probable that
we may be held jointly liable with hosts for collecting and remitting such
taxes; and (vii) restructuring charges.

The above items are excluded from our Adjusted EBITDA measure because these
items are non-cash in nature, or because the amount and timing of these items is
unpredictable, not driven by core results of operations and renders comparisons
with prior periods and competitors less meaningful. We believe Adjusted EBITDA
provides useful information to investors and others in understanding and
evaluating our results of operations, as well as provides a useful measure for
period-to-period comparisons of our business performance. Moreover, we have
included Adjusted EBITDA in this Quarterly Report on Form 10-Q because it is a
key measurement used by our management internally to make operating decisions,
including those related to operating expenses, evaluating performance, and
performing strategic planning and annual budgeting.

Adjusted EBITDA also excludes certain items related to transactional tax matters, for which management believes it is probable that we may be held jointly liable with hosts in certain jurisdictions, and we urge investors to review the detailed disclosure regarding these matters included in the subsection titled "-Critical Accounting Policies and Estimates-Lodging Tax Obligations," as well as the notes to our consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Adjusted EBITDA has limitations as a financial measure, should be considered as supplemental in nature, and is not meant as a substitute for the related financial information prepared in accordance with GAAP. These limitations include the following:



•Adjusted EBITDA does not reflect interest income (expense) and other income
(expense), net, which include loss on extinguishment of debt and unrealized and
realized gains and losses on foreign currency exchange, investments, and
financial instruments, including the warrants issued in connection with a term
loan agreement entered into in April 2020. We amended the anti-dilution feature
in the warrant agreements in March 2021. The balance of the warrants of
$1.3 billion was reclassified from liability to equity as the amended warrants
met the requirements for equity classification and are no longer remeasured at
each reporting period;
•Adjusted EBITDA excludes certain recurring, non-cash charges, such as
depreciation of property and equipment and amortization of intangible assets,
and although these are non-cash charges, the assets being depreciated and
amortized may have to be replaced in the future, and Adjusted EBITDA does not
reflect all cash requirements for such replacements or for new capital
expenditure requirements;
•Adjusted EBITDA excludes stock-based compensation expense, which has been, and
will continue to be for the foreseeable future, a significant recurring expense
in our business and an important part of our compensation strategy as well as
stock-settlement obligations, which represent employer and related taxes related
to the IPO;
•Adjusted EBITDA excludes acquisition-related impacts consisting of gains
(losses) recognized on changes in the fair value of contingent consideration
arrangements. The contingent consideration, which was in the form of equity, was
valued as of the acquisition date and is marked-to-market at each reporting
period based on factors including our stock price. The changes in fair value of
contingent consideration were insignificant prior to the fourth quarter of 2020;
•Adjusted EBITDA does not reflect net changes to reserves for lodging taxes for
which management believes it is probable that we may be held jointly liable with
hosts for collecting and remitting such taxes; and
•Adjusted EBITDA does not reflect restructuring charges, which include severance
and other employee costs, lease impairments, and contract amendments and
terminations.

Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, including net loss and our other GAAP results.



For the three months ended March 31, 2021, Adjusted EBITDA was $(58.6) million
compared to Adjusted EBITDA for the three months ended March 31, 2020 of
$(334.3) million. This favorable change was due to several factors including
higher average daily rates ("ADRs"). Supporting our ADRs were a continuation of
trends that we saw in 2020, such as the strength of bookings in North America,
where ADRs tend to be higher than other parts of the world. This was also
supported by more guests booking entire homes, relative to private or shared
rooms, as well as booking in non-urban and low-density urban areas, where ADRs
tend to be higher. In addition, during the three months ended March 31, 2021,
there were fewer cancellations and a decrease in amounts paid to customers
compared to the same prior year period. In the first
                                       27
--------------------------------------------------------------------------------


quarter of 2020, due to the global pandemic, we had elevated cancellations and
we applied our extenuating circumstances policy to cancellations resulting from
COVID-19, which resulted in a significant reduction to revenue in March 2020.
Lastly, during the three months ended March 31, 2021, we reduced overall fixed
and variable costs, particularly our performance marketing expense as compared
to the same prior year period.

Free Cash Flow



We define Free Cash Flow as net cash provided by (used in) operating activities
less purchases of property and equipment. We believe that Free Cash Flow is a
meaningful indicator of liquidity that provides information to our management
and investors about the amount of cash generated from operations, after
purchases of property and equipment, that can be used for investment in our
business and for acquisitions as well as to strengthen our balance sheet. Our
Free Cash Flow is impacted by the timing of GBV because we collect our service
fees at the time of booking, which is generally before a stay or experience
occurs. Funds held on behalf of our hosts and guests and amounts payable to our
hosts and guests do not impact Free Cash Flow, except interest earned on these
funds. Free Cash Flow has limitations as an analytical tool and should not be
considered in isolation or as a substitute for analysis of other GAAP financial
measures, such as net cash provided by (used in) operating activities. Free Cash
Flow does not reflect our ability to meet future contractual commitments and may
be calculated differently by other companies in our industry, limiting its
usefulness as a comparative measure.

For the three months ended March 31, 2021, Free Cash Flow was $486.7 million,
representing 55% of revenue, compared to $(585.5) million for the three months
ended March 31, 2020. Free Cash Flow increased for the three months ended March
31, 2021 primarily due to the increase in Nights and Experiences Booked and GBV
supported by people yearning to travel and the rollout of vaccines, combined
with higher revenue and cost reductions.

Seasonality

Our business is seasonal, reflecting typical travel behavior patterns over the
course of the calendar year. In a typical year, the first, second,
and third quarters have higher Nights and Experiences Booked than the fourth
quarter, as guests plan for travel during the peak travel season, which is in
the third quarter for North America and EMEA. Our business metrics, including
GBV and Adjusted EBITDA, can also be impacted by the timing of holidays and
other events. We experience seasonality in our GBV that is generally consistent
with the seasonality of Nights and Experiences Booked. Revenue and Adjusted
EBITDA have historically been, and are expected to continue to be, highest in
the third quarter when we have the most check-ins, which is the point at which
we recognize revenue. Seasonal trends in our GBV impact Free Cash Flow for any
given quarter. Our costs are relatively fixed across quarters or vary in line
with the volume of transactions, and we historically achieve our highest GBV in
the first and second quarters of the year with comparatively lower check-ins. As
a result, increases in unearned fees make our Free Cash Flow and Free Cash Flow
as a percentage of revenue the highest in the first two quarters of the year. We
typically see a slight decline in GBV and a peak in check-ins in the third
quarter, which results in a decrease in unearned fees and lower sequential level
of Free Cash Flow, and a greater decline in GBV in the fourth quarter, where
Free Cash Flow is typically negative. As our business matures, other seasonal
trends may develop, or these existing seasonal trends may become more extreme.

We have seen COVID-19 overwhelm the historical patterns of seasonality in our
GBV, revenue, Adjusted EBITDA, and Free Cash Flow as a result of travel
restrictions and changing travel preferences relating to the COVID-19 pandemic.
While we expect this impact on seasonality to continue as long as COVID-19 is
impacting travel patterns globally, we have seen the time between when guests
make their bookings on our platform and when they expect to complete their stays
increase and return to pre-COVID levels. Typically, booking lead times
sequentially lengthen from the fourth quarter to the first quarter when guests
start to book travel for later in the year. Even taking normal seasonal patterns
into consideration, we have seen lead times lengthen during the first quarter of
2021. In March 2021, lead times were almost on par with those of the same period
in 2019.

Components of Results of Operations

Revenue



Our revenue consists of service fees, net of incentives and refunds, charged to
our customers. We consider both hosts and guests to be our customers. For stays,
service fees, which are charged to customers as a percentage of the value of the
booking, excluding taxes, vary based on factors specific to the booking, such as
booking value, the duration of the booking, geography, and host type. For
experiences, we only earn a host fee. Substantially all of our revenue comes
from stays booked on our platform. Incentives include our referral programs and
marketing promotions to encourage the use of our platform and attract new
customers, while our refunds to customers are part of our customer support
activities.
We experience a difference in timing between when a booking is made and when we
recognize revenue, which occurs upon check-in. We record the service fees that
we collect from customers prior to check-in on our balance sheet as unearned
fees. Revenue is net of incentives and refunds provided to customers totaling
$173.1 million and $25.9 million for the three months ended March 31, 2020 and
2021, respectively, representing 21% and 3% of revenue, respectively. The
elevated level of incentives and refunds provided to customers during the three
months ended March 31, 2020 was related to payments made to support hosts
impacted by increased guest cancellations and COVID-19 related guest
cancellation coupons.
Cost of Revenue
Cost of revenue includes payment processing costs, including merchant fees and
chargebacks, costs associated with third-party data centers used to host our
platform, and amortization of internally developed software and acquired
technology. Because we act as the merchant of record, we incur all payment
processing costs associated with our bookings, and we have chargebacks, which

account takeovers and other fraudulent activities. We expect our cost of revenue
will continue to increase on an absolute dollar basis for the foreseeable future
to the extent that we continue to see growth on our platform. Cost of revenue
may vary as a percentage of revenue from year to year based on activity on our
platform and may also vary from quarter to quarter as a percentage of revenue
based on the seasonality of our business and the difference in the timing of
when bookings are made and when we recognize revenue.
Operations and Support

Operations and support expense primarily consists of personnel-related expenses
and third-party service provider fees associated with community support provided
via phone, email, and chat to hosts and guests; customer relations costs, which
include refunds and credits related to customer satisfaction and expenses
associated with our host protection programs; and allocated costs for facilities
and information technology. We expect that operations and support expense will
continue to increase on an absolute dollar basis for the foreseeable future to
the extent that we continue to see growth on our platform. We also expect
operations and support expense as a percentage of revenue in the first half of
2021 will be higher than that of the second half, as we continue to invest in
trust and safety programs and scale our frontline community support staff in
preparation for the travel rebound. We are also investing in the near-term in
initiatives to reduce customer contact rates and improve the operational
efficiency of our operations and support organization, which we expect will
decrease operations and support expense as a percentage of revenue over the
longer term. We incurred additional operations and support expense during 2020,
specifically the fourth quarter of 2020 when we completed our IPO, as a result
of the stock-based compensation expense associated with our RSUs and anticipate
additional stock-based compensation expense going forward.

Product Development
Product development expense primarily consists of personnel-related expenses and
third-party service provider fees incurred in connection with the development of
our platform, and allocated costs for facilities and information technology. We
expect that our product development expense will increase on an absolute dollar
basis and will vary from period to period as a percentage of revenue for the
foreseeable future as we continue to invest in product development activities
relating to ongoing improvements to and maintenance of our technology platform
and other programs, including the hiring of personnel to support these efforts.
We incurred additional product development expense during 2020, specifically the
fourth quarter of 2020 when we completed our IPO, as a result of the stock-based
compensation expense associated with our RSUs and anticipate additional
stock-based compensation expense going forward.
Sales and Marketing
Sales and marketing expense primarily consists of brand and performance
marketing, personnel-related expenses, including those related to our field
operations, policy and communications, portions of referral incentives and
coupons, and allocated costs for facilities and information technology. We
expect our sales and marketing expense will vary from period to period as a
percentage of revenue for the foreseeable future, and over the long term, we
expect it will decline as a percentage of revenue relative to 2019. We expect
that sales and marketing expense as a percentage of revenue in the first half of
2021 will be higher than that of the second half. This is partially due to the
marketing campaign that we began running in February 2021 in advance of the
summer travel season. We incurred additional sales and marketing expense during
2020, specifically the fourth quarter of 2020 when we completed our IPO, as a
result of the stock-based compensation expense associated with our RSUs and
anticipate additional stock-based compensation expense going forward.
General and Administrative
General and administrative expense primarily consists of personnel-related
expenses for management and administrative functions, including finance and
accounting, legal, and human resources. General and administrative expense also
includes certain professional services fees, general corporate and director and
officer insurance, allocated costs for facilities and information technology,
indirect taxes, including lodging tax reserves for which we may be held jointly
liable with hosts for collecting and remitting such taxes, and bad debt expense.
We expect to incur additional general and administrative expense as a result of
operating as a public company, including expenses to comply with the rules and
regulations of the SEC and Listing Rules of Nasdaq, as well as higher expenses
for corporate insurance, director and officer insurance, investor relations, and
professional services. Overall, we expect our general and administrative expense
will vary from period to period as a percentage of revenue for the foreseeable
future. We incurred additional general and administrative expense during 2020,
specifically the fourth quarter of 2020 when we completed our IPO, as a result
of the stock-based compensation expense associated with our RSUs and anticipate
additional stock-based compensation expense going forward.
Restructuring Charges
Restructuring charges primarily consist of costs associated with a global
workforce reduction in May 2020, lease impairments, and costs associated with
amendments and terminations of contracts, including commercial agreements with
service providers.
Interest Income
Interest income consists primarily of interest earned on our cash, cash
equivalents, marketable securities, and amounts held on behalf of customers.

Interest Expense
Interest expense consists primarily of interest associated with various indirect
tax reserves, amortization of debt issuance costs associated with our
$1.0 billion five-year unsecured revolving Credit and Guarantee Agreement (the
"2016 Credit Facility"), interest expense and
                                       30
--------------------------------------------------------------------------------


amortization of debt issuance costs associated with our term loan agreements
entered into in April 2020, and the loss on extinguishment of debt related to
the repayment of the first and second lien loans in March 2021.
Other Income (Expense), Net
Other income (expense), net consists primarily of realized and unrealized gains
and losses on foreign currency transactions and balances, the change in fair
value of investments and financial instruments, including the warrants issued in
connection with a term loan agreement entered into in April 2020, and our share
of income or loss from our equity method investments.
Our platform generally enables guests to make payments in the currency of their
choice to the extent that the currency is supported by Airbnb, which may not
match the currency in which the host elects to be paid. As a result, in those
cases, we bear the currency risk of both the guest payment as well as the host
payment due to timing differences in such payments. In 2019, we began entering
into derivative contracts to offset a portion of our exposure to the impact of
movements in currency exchange rates on our transactional balances denominated
in currencies other than the U.S. dollar. The effects of these derivative
contracts are reflected in other income (expense), net.
Provision for (Benefit from) Income Taxes
We are subject to income taxes in the United States and foreign jurisdictions in
which we do business. Foreign jurisdictions have different statutory tax rates
than those in the United States. Additionally, certain of our foreign earnings
may also be taxable in the United States. Accordingly, our effective tax rate is
subject to significant variation due to several factors, including variability
in our pre-tax and taxable income and loss and the mix of jurisdictions to which
they relate, intercompany transactions, changes in how we do business,
acquisitions, investments, tax audit developments, changes in our deferred tax
assets and liabilities and their valuation, foreign currency gains and losses,
changes in statutes, regulations, case law, and administrative practices,
principles, and interpretations related to tax, including changes to the global
tax framework, competition, and other laws and accounting rules in various
jurisdictions, and relative changes of expenses or losses for which tax benefits
are not recognized. Additionally, our effective tax rate can vary based on the
amount of pre-tax income or loss. For example, the impact of discrete items and
non-deductible expenses on our effective tax rate is greater when our pre-tax
income is lower.

We have a valuation allowance for our net deferred tax assets, including federal
and state net operating loss carryforwards, tax credits, and intangible assets.
We expect to maintain these valuation allowances until it becomes more likely
than not that the benefit of our deferred tax assets will be realized by way of
expected future taxable income in the United States. We recognize accrued
interest and penalties related to unrecognized tax benefits in the provision for
(benefit from) income taxes.

In the event that we experience an ownership change within the meaning of
Section 382 of the Internal Revenue Code, our ability to utilize net operating
losses, tax credits, and other tax attributes may be limited. The most recent
analysis of our historical ownership changes was completed through March 31,
2021. Based on the analysis, we do not anticipate a permanent limitation on the
existing tax attributes under Section 382, although subsequent changes in our
ownership structure may create such a limitation.

We are currently under examination for income taxes by the Internal Revenue
Service ("IRS") for the years 2013, 2016, 2017, and 2018. In December 2020, we
received a Notice of Proposed Adjustment from the IRS for the 2013 tax year
relating to the valuation of our international intellectual property which was
sold to a subsidiary in 2013. The notice proposes an increase to our U.S.
taxable income that could result in additional income tax expense and cash tax
liability of $1.35 billion, plus penalties and interest, which exceeds our
current reserve recorded in our consolidated financial statements by more than
$1.0 billion. We intend to vigorously contest the IRS's proposed adjustment,
including through all administrative and, if necessary, judicial remedies which
may include: entering into administrative settlement discussions with the IRS
Independent Office of Appeals ("IRS Appeals") in 2021, and if necessary
petitioning the U.S. Tax Court ("Tax Court") for redetermination if an
acceptable outcome cannot be reached with IRS Appeals, and finally, and if
necessary, appealing the Tax Court's decision to the appropriate appellate
court. If the IRS prevails in the assessment of additional tax due based on its
position and such tax and related interest and penalties, if any, exceeds our
current reserves, such outcome could have a material adverse impact on our
financial position and results of operations, and any assessment of additional
tax could require a significant cash payment and have a material adverse impact
on our cash flow.

Comparison of the Three Months Ended March 31, 2020 and 2021
Revenue
                 Three Months Ended March 31,
                                                     2020 to 2021 %

              (in thousands, except percentages)
Revenue     $       841,830             $ 886,936               5  %


Revenue increased $45.1 million, or 5%, for the three months ended March 31,
2021 compared to the three months ended March 31, 2020, primarily due to higher
ADRs, partially offset by a decrease in the number of check-ins related to
Nights and Experiences Booked on our platform. In addition, during the three
months ended March 31, 2020, we had higher reductions to revenue largely
attributable to payments made to customers related to our extenuating
circumstances policy for cancellations resulting from COVID-19 totaling $106.5
million, the majority of which was recorded as reduction to revenue. Service
fees as a percentage of booking value, exclusive of taxes, increased marginally
as compared to the same prior year period. On a constant currency basis, revenue
increased 3% compared to the three months ended March 31, 2020.
Cost of Revenue
                             Three Months Ended March 31,
                                                                 2020 to 2021 %
                                2020                2021             Change
                          (in thousands, except percentages)
Cost of revenue         $         277,772     $      254,515               (8) %
Percentage of revenue                  33   %             29  %


Cost of revenue decreased $23.3 million, or 8%, for the three months ended March
31, 2021 compared to the three months ended March 31, 2020. The change was
primarily due to a $14.1 million decrease in the cost of data hosting services,
a $11.9 million decrease in chargebacks and a $10.1 million decrease in
third-party outside support services, partially offset by a $8.8 million
increase in amortization expense for internally developed software and acquired
technology and a $5.3 million increase in merchant fees. For the three months
ended March 31, 2020 and 2021, payment processing costs, consisting of merchant
fees and chargebacks, totaled $191.9 million and $185.3 million, respectively,
which represented 3% and 2% of GBV, respectively. The decrease in data hosting
primarily resulted from lower usage. The decrease in payment processing costs
resulted from lower chargeback expense attributable to elevated chargeback
activity related to COVID-19 during the three months ended March 31, 2020.

Percentage of revenue                     26   %             21  %



Operations and support expense decreased $36.4 million, or 16%, for the three
months ended March 31, 2021 compared to the three months ended March 31, 2020.
The change was primarily due to a $53.9 million decrease in third-party
community support personnel and customer relations costs, partially offset by a
$14.3 million increase in payroll-related expenses, predominantly comprised of
stock-based compensation related to RSUs. The decrease in spending on
third-party community support personnel and customer relations costs was largely
due to fewer check-ins.
Product Development
                             Three Months Ended March 31,
                                                                 2020 to 2021 %

Product development     $         258,819     $      363,061               40  %
Percentage of revenue                  31   %             41  %


Product development expense increased $104.2 million, or 40%, for the three
months ended March 31, 2021 compared to the three months ended March 31, 2020.
The change was primarily due to a $129.6 million increase in payroll-related
expenses, predominantly comprised of stock-based compensation related to RSUs,
partially offset by a decrease in allocated costs for facilities and information
technology of $16.7 million primarily due to the reduction in headcount.

Sales and marketing expense decreased $88.1 million, or 28%, for the three
months ended March 31, 2021 compared to the three months ended March 31, 2020.
The change was primarily due to a $71.7 million decrease in marketing activities
and a $9.3 million decrease in expenses for third-party service providers,
partially offset by a $17.8 million increase in payroll-related expenses,
predominantly comprised of stock-based compensation related to RSUs. Total brand
and performance marketing decreased $98.6 million, driven by a reduction of
performance marketing, partially offset by an increase in brand marketing. In
March 2020, driven by COVID-19, we paused our sales and marketing investments in
new initiatives and our performance marketing spend. We implemented a marketing
strategy that shifted our marketing mix towards brand marketing spend and away
from spending on performance marketing. During the three months ended March 31,
2021, we launched our Made possible by Hosts television and digital channels
campaign in five of our largest markets. We also launched an accompanying
digital campaign focused on recruiting new hosts. Total field operations and
policy expense increased $10.6 million from the same period in 2020, which
included $3.0 million of changes in the fair value of contingent consideration
arrangements related to an acquisition completed in 2019.

                                                                       2020 to 2021 %

Percentage of revenue                       11    %             21  %


General and administrative expense increased $98.0 million, or 107%, for the
three months ended March 31, 2021 compared to the three months ended March 31,
2020. The change was primarily due to a prior year $81.7 million reduction in
our reserve for lodging taxes in jurisdictions in which management no longer
believed a liability was probable following a favorable outcome in a related
legal proceeding, and an increase of $46.6 million in payroll-related expenses,
predominantly comprised of stock-based compensation related to RSUs. These
movements were partially offset by a $19.8 million decrease in bad debt expense
and a $13.3 million reduction in certain employee benefits and related
employment taxes and associated penalties, resulting from a settlement
agreement.
Restructuring Charges
                              Three Months Ended March 31,
                                                                   2020 to 2021 %

Restructuring charges totaled $112.0 million for the three months ended March
31, 2021. During the period, we ceased use of a leased office and made available
for sublease resulting in an additional lease impairment.
Interest Income and Expense
                             Three Months Ended March 31,

Percentage of revenue                 -    %             (48) %


*Not meaningful

Interest income decreased $10.6 million, or 78%, for the three months ended
March 31, 2021 compared to the three months ended March 31, 2020. The decrease
was primarily due to a decline in interest rates and our investment portfolio
mix, which was largely invested in short-term, high-quality bonds. Interest
expense increased $423.4 million for the three months ended March 31, 2021
compared to the three months ended March 31, 2020 primarily due to the interest
of $41.5 million owed on the term loans issued in April 2020 and the $377.2
million loss on extinguishment of debt resulting from retirement of these term
loans in March 2021. Refer to the section titled "Liquidity and Capital
Resources - Loan Agreements" below for further information.

Other expense, net increased $253.3 million for the three months ended March 31,
2021 compared to the three months ended March 31, 2020. The change was primarily
driven by $292.0 million of fair value remeasurement on our warrants issued in
connection with our second lien loan and a $36.7 million increase in net
realized and unrealized foreign exchange losses, partially offset by a $26.2
million increase in net realized and unrealized gains on our investments and
impairment charges recorded during 2020 totaling $45.6 million. During the
quarter ended March 31, 2021, the warrants issued in connection with our second
lien loan were reclassified to equity and will no longer require fair value
remeasurement.
Provision for (Benefit from) Income Taxes
                                                       Three Months Ended March 31,

*Not meaningful

The provision for income taxes in the three months ended March 31, 2021
increased $22.8 million, compared to the same period in 2020, primarily due to
the benefit recognized in the prior year quarter from the five-year net
operating loss carryback provision of the CARES Act and increased foreign taxes.
Liquidity and Capital Resources
In December 2020, upon the completion of our IPO, we received net proceeds of
$3.7 billion after deducting underwriting discounts and commissions of $79.3
million and offering expenses of $9.8 million. We used a portion of these net
proceeds to satisfy the tax withholding and remittance obligations of
approximately $1.6 billion related to the settlement of our outstanding RSUs in
connection with our IPO.

As of March 31, 2021, our principal sources of liquidity were cash and cash
equivalents and marketable securities totaling $6.6 billion. As of March 31,
2021, cash and cash equivalents of $4.5 billion included $1.4 billion held by
foreign subsidiaries. Cash and cash equivalents consist of checking and
interest-bearing accounts and highly-liquid securities with an original maturity
of 90 days or less. As of March 31, 2021, marketable securities of $2.1 billion
included an immaterial amount held by foreign subsidiaries. Marketable
securities consist of corporate debt securities, mutual funds, highly-liquid
debt instruments of the U.S. government and its agencies, and certificates of
deposit. These amounts do not include funds of $4.0 billion as of March 31, 2021
that we held for bookings in advance of guests completing check-ins that we
record separately on our balance sheet in funds receivable and amounts held on
behalf of customers with a corresponding liability in funds payable and amounts
payable to customers.

Cash, cash equivalents, and marketable securities held outside the United States
may be repatriated, subject to certain limitations, and would be available to be
used to fund our domestic operations. However, repatriation of such funds may
result in additional tax liabilities. We believe that our existing cash, cash
equivalents, and marketable securities balances in the United States are
sufficient to fund our working capital needs in the United States.

Convertible Senior Notes

On March 8, 2021, we issued $2.0 billion aggregate principal amount of 0% convertible senior notes due 2026 (the "2026 Notes") pursuant to an indenture, dated March 8, 2021 (the "Indenture"), between us and U.S. Bank National Association, as trustee. The 2026 Notes were offered and sold in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act").

The 2026 Notes are senior unsecured obligations and will not bear regular interest. The 2026 Notes mature on March 15, 2026, unless earlier converted, redeemed or repurchased. The net proceeds from the 2026 Notes were $1,979.0 million, after deducting the initial purchasers' discounts and commissions and debt issuance costs.



The initial conversion rate for the 2026 Notes is 3.4645 shares of our Class A
common stock per $1,000 principal amount of 2026 Notes, which is equivalent to
an initial conversion price of approximately $288.64 per share of the Class A
common stock. The conversion rate is subject to adjustment under certain
circumstances in accordance with the terms of the Indenture.
                                       36
--------------------------------------------------------------------------------



The 2026 Notes will be convertible at the option of the holders prior to the
close of business on the business day immediately preceding March 15, 2026 only
under the following circumstances:

•during any calendar quarter (and only during such calendar quarter) commencing
after the calendar quarter ending on June 30, 2021, if the last reported sale
price per share of our common stock exceeds 130% of the conversion price for
each of at least 20 trading days, whether or not consecutive, during the 30
consecutive trading days ending on, and including, the last trading day of the
immediately preceding calendar quarter;
•during the five consecutive business days immediately after any 10 consecutive
trading day period (such 10 consecutive trading day period, the "measurement
period") if the trading price per $1,000 principal amount of notes for each
trading day of the measurement period is less than 98% of the product of the
last reported sale price per share of our common stock on such trading day and
the conversion rate on such trading day;
•upon the occurrence of certain corporate events or distributions on our common
stock, as described in this offering memorandum;
•or if we call such notes for redemption; and
•at any time from, and including, December 15, 2025 until the close of business
on the second scheduled trading day immediately before the maturity date.

Upon conversion, we may satisfy our conversion obligation by paying or
delivering, as applicable, cash, shares of our Class A common stock or a
combination of cash and shares of our Class A common stock, at our election,
based on the applicable conversion rate. Holders of the 2026 Notes who convert
their 2026 Notes in connection with certain corporate events that constitute a
make-whole fundamental change (as defined in the Indenture) are, under certain
circumstances, entitled to an increase in the conversion rate. Additionally in
the event of a corporate event constituting a fundamental change (as defined in
the Indenture), holders of the 2026 Notes may require us to repurchase all or a
portion of their 2026 Notes at a repurchase price equal to 100% of the principal
amount of the Notes being repurchased.

Capped Calls



On March 3, 2021, in connection with the pricing of the 2026 Notes, we entered
into privately negotiated capped call transactions (the "Capped Calls") with
certain of the initial purchasers and other financial institutions (the "option
counterparties") at a cost of approximately $100.2 million. The Capped Calls
cover, subject to anti-dilution adjustments, the number of shares of Class A
common stock initially underlying the 2026 Notes sold in the offering. By
entering into the Capped Calls, we expect to reduce the potential dilution to
our common stock (or, in the event a conversion of the 2026 Notes is settled in
cash, to reduce our cash payment obligation) in the event that at the time of
conversion of the 2026 Notes our common stock price exceeds the conversion price
of the 2026 Notes. The cap price of the Capped Calls will initially be $360.80
per share of Class A common stock, which represents a premium of 100% over the
last reported sale price of the Class A common stock of $180.40 per share on
March 3, 2021, and is subject to certain customary adjustments under the terms
of the Capped Call Transactions.

The Capped Calls meet the criteria for classification in equity, are not remeasured each reporting period and included as a reduction to additional paid-in-capital within stockholders' equity.

Loan Agreements



In April 2020, we entered into a $1.0 billion First Lien Credit and Guaranty
Agreement (the "First Lien Credit Agreement," and the loans thereunder, the
"First Lien Loan"), resulting in proceeds of $961.4 million, net of debt
discount and issuance costs. The loan is due and payable in April 2025. The
underlying loan can be repaid in whole or in part prior to April 2025 at our
option, subject to applicable prepayment premiums and make-whole premiums.
Beginning in September 2020, we are required to repay the First Lien Loan in
quarterly installments equal to 0.25% of the $1.0 billion aggregate principal
amount of the First Lien Loan, with the remaining principal amount payable on
the maturity date.

In April 2020, we entered into a $1.0 billion Second Lien Credit and Guaranty
Agreement (the "Second Lien Credit Agreement," and the loans thereunder, the
"Second Lien Loan"), resulting in proceeds of $967.5 million, net of debt
discount and issuance costs. The loan is due and payable in July 2025. The
underlying loan can be repaid in whole or in part prior to July 2025 at our
option, subject to applicable prepayment premiums and make-whole premiums and
the priority of lenders under the First Lien Credit Agreement over any proceeds
we receive from the sale of collateral.

In connection with the Second Lien Loan, we issued warrants to purchase
7,934,794 shares of Class A common stock with an initial exercise price of
$28.355 per share, subject to adjustments upon the occurrence of certain
specified events, to the Second Lien Loan lenders. The warrants expire on
April 17, 2030 and the exercise price can be settled in cash or in net shares at
the holder's option. The fair value of the warrants of $116.6 million at
issuance was recorded as a liability on the condensed consolidated balance
sheet, and the warrant liability is remeasured to fair value at each reporting
date as long as the warrants remain outstanding and unexercised with changes in
fair value recorded in other income (expense), net in the condensed consolidated
statements of operations. As of December 31, 2020, the fair value of the warrant
totaled $985.2 million. We amended the anti-dilution feature in the warrant
agreements in March 2021, which resulted in a change in classification from
liability to equity. Accordingly, we recorded $292.0 million in other expense
through March 30, 2021, the modification date. The balance of $1.3 billion was
then reclassified from liability to equity as the amended warrants met the
requirements for equity classification.

The First Lien Credit Agreement and Second Lien Credit Agreement included
customary conditions to borrowing, events of default, and covenants, including
those that restrict our and our subsidiaries' ability to, among other things,
incur additional indebtedness, create or incur liens, merge or consolidate with
other companies, liquidate or dissolve, sell or transfer assets, pay dividends
or make distributions, make acquisitions, investments, loans or advances, or
payments and prepayments of junior or unsecured indebtedness, subject to certain
exceptions. As of December 31, 2020, we were in compliance with all covenants of
the First Lien Credit Agreement and Second Lien Credit Agreement.
                                       37
--------------------------------------------------------------------------------

On March 8, 2021, we repaid the principal of the First Lien and Second Lien loans of $1,995 million, which resulted in a loss of extinguishment of debt of $377.2 million, including early redemption premiums of $212.9 million and a write-off of $164.3 million of unamortized debt discount and debt issuance costs. Additionally, we incurred third-party costs, principally legal and administrative fees, of $0.1 million relating to the extinguishment of the loans.

2020 Credit Facility



In November 2020, we entered into a $500.0 million five-year senior secured
revolving Credit and Guarantee Agreement (the "Revolving Credit Agreement"),
which provides for an initial borrowing commitment by a group of lenders led by
Morgan Stanley Senior Funding, Inc. of $500.0 million (the "2020 Credit
Facility"). The 2020 Credit Facility provides a $200.0 million sub-limit for the
issuance of letters of credit. The 2020 Credit Facility has a commitment fee of
0.15% per annum on any undrawn amounts, payable quarterly in arrears. Interest
on borrowings is equal to (i) in the case of LIBOR borrowings, 1.5% plus LIBOR,
subject to a floor of 0%, or (ii) in the case of base rate borrowings, 0.5% plus
the greatest of (a) the federal funds effective rate plus 0.5%, (b) the prime
rate, and (c) LIBOR for a one-month period plus 1%, in each case subject to a
floor of 1%.

The Revolving Credit Agreement includes customary conditions to borrowing,
events of default, and covenants, including a minimum liquidity covenant
requiring us to have liquidity of at least $200.0 million as of the last day of
each fiscal quarter and those that restrict our and our subsidiaries' ability
to, among other things, incur additional indebtedness, create or incur liens,
merge or consolidate with other companies, liquidate or dissolve, sell or
transfer assets, pay dividends or make distributions, subject to certain
exceptions.

As of March 31, 2021, there were no borrowings outstanding on the 2020 Credit Facility and outstanding letters of credit totaled approximately $18.4 million.

2016 Credit Facility



In April 2020, we terminated our 2016 Credit Facility, which provided an initial
borrowing commitment by a group of lenders led by Bank of America, N.A. of
$1.0 billion. The 2016 Credit Facility also provided a $100.0 million sub-limit
for the issuance of letters of credit.

As of December 31, 2019, there were no borrowings outstanding on the 2016 Credit
Facility and outstanding letters of credit totaled $53.0 million. The 2016
Credit Facility contained customary affirmative and negative covenants,
including restrictions on our and certain of our subsidiaries' ability to incur
debt and liens, undergo fundamental changes, and pay dividends or other
distributions, as well as certain financial covenants. On April 17, 2020, we
terminated the 2016 Credit Facility. Certain letters of credit under the 2016
Credit Facility were transferred to new issuers upon the termination of the 2016
Credit Facility. As of March 31, 2021, letters of credit formerly under the 2016
Credit Facility totaled $19.3 million and were collateralized by $19.9 million
of restricted cash on the condensed consolidated balance sheet.
We believe that our current available cash, cash equivalents, and marketable
securities will be sufficient to meet our operational cash needs for the
foreseeable future. Our future capital requirements, however, will depend on
many factors, including, but not limited to our growth, headcount, ability to
attract and retain hosts and guests on our platform, capital expenditures,
acquisitions, introduction of new products and offerings, timing and extent of
spending to support our efforts to develop our platform, and expansion of sales
and marketing activities. Additionally, we may in the future raise additional
capital or incur additional indebtedness to continue to fund our strategic
initiatives. In the event that additional financing is required from outside
sources, we may seek to raise additional funds at any time through equity,
equity-linked arrangements, and/or debt, which may not be available on favorable
terms, or at all. If we are unable to raise additional capital when desired and
at reasonable rates, our business, results of operations, and financial
condition could be materially adversely affected. We expect our capital
expenditures in 2021 will be higher than that of 2020, but significantly lower
than 2019. The majority of our expected investments are related to offices in
North America, many of which were delayed in 2020.

Net cash used in investing activities for the three months ended March 31, 2021
was $1.2 billion, which was primarily used to purchase marketable securities of
$1.6 billion, partially offset by proceeds from sales and maturities of
marketable securities of $248.2 million and $168.7 million, respectively.
Net cash provided by investing activities for the three months ended March 31,
2020 was $2.3 million, which was primarily provided by proceeds from sales and
maturities of marketable securities of $69.3 million and $225.5 million,
respectively, partially offset by cash used to purchase marketable securities of
$277.3 million and property and equipment of $15.7 million.
Cash Provided by (Used in) Financing Activities
Net cash provided by financing activities for the three months ended March 31,
2021 was $1.6 billion, primarily reflecting proceeds from the issuance of
convertible senior notes, net of issuance costs, of $1,979 million and change in
funds payable and amounts payable to customers of $1.9 billion, partially offset
by the repayment of long-term debt and related prepayment penalty of $1,995
million and $212.9 million, respectively.
Net cash used in financing activities for the three months ended March 31, 2020
was $339.2 million, primarily reflecting the change in funds payable and amounts
payable to customers of $339.4 million.
Effect of Exchange Rates
The effect of exchange rate changes on cash, cash equivalents, and restricted
cash on our condensed consolidated statements of cash flows relates to certain
of our assets, principally cash balances held on behalf of hosts and guests,
that are denominated in currencies other than the functional currency of certain
of our subsidiaries. For the three months ended March 31, 2020 and 2021, we
recorded a $97.1 million and $72.3 million reduction in cash, cash equivalents,
and restricted cash, respectively, primarily due to the strengthening of the
U.S. dollar. The impact of exchange rate changes on cash balances can serve as a
natural hedge for the effect of exchange rates on our liabilities to our guests
and hosts.
Off-Balance Sheet Arrangements
As of March 31, 2021, we did not have any off-balance sheet arrangements, as
defined in Regulation S-K, that have or are reasonably likely to have a current
or future effect on our financial condition, results of operations, or cash
flows.
Contractual Obligations and Commitments
As of March 31, 2021, there were no material changes outside the ordinary course
of business to the contractual obligations, as disclosed in our 2020 Annual
Report, except for the repayment of the First Lien Loan and Second Lien Loan and
issuance of the 2026 Notes.
Critical Accounting Policies and Estimates
Our condensed consolidated financial statements are prepared in accordance with
accounting principles generally accepted in the United States. The preparation
of these condensed consolidated financial statements requires us to make
estimates and assumptions that affect the reported amounts of assets,
liabilities, revenue, costs, and expenses, and related disclosures. On an
ongoing basis, we evaluate our estimates and assumptions. Our actual results may
differ from these estimates under different assumptions or conditions.

We believe that of our significant accounting policies, which are described in
Note 2 to our condensed consolidated financial statements included elsewhere in
this Quarterly Report on Form 10-Q, the following accounting policies involve a
greater degree of judgment and complexity. Accordingly, these are the policies
we believe are the most critical to aid in fully understanding and evaluating
our condensed consolidated financial condition, results of operations, and cash
flows.

Revenue Recognition

We recognize revenue in accordance with ASC Topic 606, which we adopted as of
January 1, 2018 on a full retrospective basis. We generate substantially all of
our revenue from facilitating guest stays at accommodations offered by hosts on
the Airbnb platform. We consider both hosts and guests to be our customers. Our
revenue is comprised of service fees from our customers. Our single performance
obligation is identified as the facilitation of a stay, which occurs upon the
completion of a check-in event. Revenue is recognized at a point in time when
the performance obligation is satisfied upon check-in.

We evaluate the presentation of revenue on a gross versus net basis based on
whether or not we are the principal in the transaction (gross) or whether we
arrange for other parties to provide the service to guests and are the agent
(net) in the transaction. We determined that we
                                       39
--------------------------------------------------------------------------------


do not control the right to use the accommodations provided by us either before
or after completion of our service. Accordingly, we concluded that we are acting
in an agent capacity and revenue is presented net reflecting the service fees
received from our customers to facilitate a stay.

Revenue is presented net of certain payments we make to customers as part of our
referral programs and marketing promotions, collectively referred to as our
incentive programs, and refund activities. The payments are generally in the
form of coupon credits to be applied toward future bookings or as cash refunds.
We encourage the use of our platform and attract new customers through our
incentive programs. Under the referral program, the referring party ("referrer")
earns a coupon when the new host or guest ("referee") completes their first stay
on our platform. We record the incentive as a liability at the time the
incentive is earned by the referrer with the corresponding charge recorded to
sales and marketing expense. Any amounts paid in excess of the fair value of the
referral service received are recorded as a reduction of revenue. Through
marketing promotions, we issue customer coupon credits to encourage the use of
our platform. After a customer redeems such incentives, we record a reduction to
revenue at the date we record the corresponding revenue transaction. From time
to time, we issue refunds to customers in the form of cash or credits to be
applied toward a future booking. We reduce the transaction price by the
estimated amount of the payments by applying the most likely outcome method
based on known facts and circumstances and historical experience. These refunds
are recorded as a reduction to revenue.

We evaluate whether the cumulative amount of payments made to customers that are
not in exchange for a distinct good or service received from a customer exceeds
the cumulative revenue earned since inception of the customer relationship. Any
cumulative payments in excess of cumulative revenue are presented as operating
expenses in our condensed consolidated statements of operations.
Lodging Tax Obligations

Some states, cities, and localities in the United States and elsewhere in the
world impose transient occupancy or lodging accommodations taxes ("lodging
taxes") on the use or occupancy of lodging accommodations or other traveler
services. We collect and remit lodging taxes in more than 29,800 jurisdictions
on behalf of our hosts, and lodging taxes are primarily collected in the United
States. Such lodging taxes are generally remitted to tax jurisdictions within a
30 to 90-day period following the end of each month.
In jurisdictions where we do not collect and remit lodging taxes, the
responsibility for collecting and remitting these taxes, if applicable,
generally rests with hosts. We estimate liabilities for a certain number of
jurisdictions with respect to state, city, and local taxes related to lodging
where we believe it is probable that Airbnb could be held jointly liable with
hosts for collecting and remitting such taxes and the related amounts can be
reasonably estimated. Our accrued obligations related to lodging taxes,
including estimated penalties and taxes, totaled $52.9 million and $53.7 million
as of December 31, 2020 and March 31, 2021, respectively, and changes to this
reserve are recorded in general and administrative expense in our condensed
consolidated statements of operations.
We are currently involved in a number of lawsuits brought by certain states and
localities involving the payment of lodging taxes. These jurisdictions are
asserting that we are liable or jointly liable with hosts to collect and remit
lodging taxes. These lawsuits are in various stages and we continue to
vigorously defend these claims. We believe that the statutes at issue impose a
lodging tax obligation on the person exercising the taxable privilege of
providing accommodations, our hosts. The ultimate resolution of these lawsuits
cannot be determined at this time.
Evaluating potential outcomes for lodging taxes is inherently uncertain and
requires us to utilize various judgments, assumptions and estimates in
determining our reserves. A variety of factors could affect our potential
obligation for collecting and remitting such taxes which include, but are not
limited to, whether we determine, or any tax authority asserts, that we have a
responsibility to collect lodging and related taxes on either historic or future
transactions; the introduction of new ordinances and taxes which subject our
operations to such taxes; or the ultimate resolution of any historic claims that
may be settled through negotiation. Accordingly, the ultimate resolution of
lodging taxes may be greater or less than reserve amounts we have established.
Income Taxes

We are subject to income taxes in the United States and foreign jurisdictions.
We account for income taxes using the asset and liability method. We account for
uncertainty in tax positions by recognizing a tax benefit from uncertain tax
positions when it is more likely than not that the position will be sustained
upon examination. Evaluating our uncertain tax positions, determining our
provision for (benefit from) income taxes, and evaluating the impact of the Tax
Cuts and Jobs Act, are inherently uncertain and require making judgments,
assumptions, and estimates.
While we believe that we have adequately reserved for our uncertain tax
positions, no assurance can be given that the final tax outcome of these matters
will not be different. We adjust these reserves in light of changing facts and
circumstances, such as the closing of a tax audit. To the extent that the final
tax outcome of these matters is different than the amounts recorded, such
differences will impact the provision for (benefit from) income taxes and the
effective tax rate in the period in which such determination is made.
The provision for (benefit from) income taxes includes the impact of reserve
provisions and changes to reserves as well as the related net interest and
penalties. In addition, we are subject to the continuous examination of our
income tax returns by the United States Internal Revenue Service and other tax
authorities that may assert assessments against us. We regularly assess the
likelihood of adverse outcomes resulting from these examinations and assessments
to determine the adequacy of our provision for (benefit from) income taxes.

Goodwill and Impairment of Long-Lived Assets

Goodwill represents the excess of the purchase price over the fair value of net
assets acquired in a business combination. We have one reporting unit. We test
goodwill for impairment at least annually, in the fourth quarter, and whenever
events or changes in circumstances indicate that goodwill might be impaired. As
a result of the goodwill impairment assessment, management concluded goodwill
was not impaired as of December 31, 2020 and does not believe that its reporting
unit is at risk of failing the impairment test since the fair value of the
reporting unit substantially exceeded the carrying value.
Long-lived assets that are held and used by us are reviewed for impairment when
events or changes in circumstances indicate that the carrying amount of the
asset may not be recoverable. Determination of recoverability of long-lived
assets is based on an estimate of the undiscounted cash flows resulting from the
use of the asset group and its eventual disposition. If the carrying value of
the long-lived asset group is not recoverable on an undiscounted cash flow
basis, we recognize impairment to the extent that the carrying value exceeds its
fair value. We determine fair value through various valuation techniques
including discounted cash flow models, quoted market values, and third-party
independent appraisals.
Any impairments to right-of-use ("ROU") assets, leasehold improvements, or other
assets as a result of a sublease, abandonment, or other similar factor are
initially recognized when a decision to do so is made and recorded as an
operating expense. Similar to other long-lived assets, management tests ROU
assets for impairment whenever events or changes in circumstances occur that
could impact the recoverability of these assets. For lease assets, such
circumstances would include subleases that do not fully recover the costs of the
associated leases or a decision to abandon the use of all or part of an asset.
For the three months ended March 31, 2021, we recorded $75.3 million of ROU
asset impairment charges and $37.2 million leasehold improvements impairment
charges within restructuring charges in the condensed consolidated statement of
operations.
Significant judgment and estimates are required in assessing impairment of
goodwill and long-lived assets, including identifying whether events or changes
in circumstances require an impairment assessment, estimating future cash flows,
and determining appropriate discount rates. Our estimates of fair value are
based on assumptions believed to be reasonable, but which are inherently
uncertain and unpredictable and, as a result, actual results may differ from
estimates.
Recent Accounting Pronouncements
See Note 2 to our condensed consolidated financial statements for a description
of recently adopted accounting pronouncements and recently issued accounting
pronouncements not yet adopted.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
Our substantial operations around the world expose us to various market risks.
These risks primarily include foreign currency risk and investment risk.
Foreign Currency Exchange Risk
We offer the ability to transact on our platform in over 40 currencies, of which
the most significant foreign currencies to our operations in the first quarter
of 2021 were the Euro, British Pound, Australian Dollar, Canadian Dollar,
Brazilian Real, Chinese Yuan and Mexican Peso. Our international revenue, as
well as costs and expenses denominated in foreign currencies, expose us to the
risk of fluctuations in foreign currency exchange rates against the U.S. dollar.
Accordingly, we are subject to foreign currency risk, which may adversely impact
our financial results.
We have foreign currency exchange risks related primarily to:

•revenue and cost of revenue associated with bookings on our platform
denominated in currencies other than the U.S. dollar;
•balances held as funds receivable and amounts held on behalf of customers and
funds payable and amounts payable to customers;
•unbilled amounts for confirmed bookings under the terms of our Pay Less Upfront
program; and
•intercompany balances primarily related to our payment entities that process
customer payments.
For revenue and cost of revenue associated with bookings on our platform outside
of the United States, we generally receive net foreign currency amounts and
therefore benefit from a weakening of the U.S. dollar and are adversely affected
by a strengthening of the U.S. dollar. Movements in foreign exchange rates are
recorded in other income (expense), net in our condensed consolidated statements
of operations. Furthermore, our platform generally enables guests to make
payments in the currency of their choice to the extent that the currency is
supported by Airbnb, which may not match the currency in which the host elects
to be paid. As a result, in those cases, we bear the currency risk of both the
guest payment as well as the host payment due to timing differences in such
payments.
In 2019, we began entering into foreign currency derivative contracts to protect
against foreign exchange risks. Presently, these hedges are primarily designed
to manage foreign exchange risk associated with balances held as funds payable
and amounts payable to customers and unbilled amounts for confirmed bookings
under the terms of our Pay Less Upfront program. These contracts reduce, but do
not entirely eliminate, the impact of currency exchange rate movements on our
assets and liabilities.
We may choose not to hedge the risk associated with our foreign currency
exposures, primarily if such exposure acts as a natural hedge for offsetting
amounts denominated in the same currency or if the currency is too difficult or
too expensive to hedge.
                                       41
--------------------------------------------------------------------------------


We have experienced and will continue to experience fluctuations in foreign
exchange gains and losses related to changes in exchange rates. If our
foreign-currency denominated assets, liabilities, revenues, or expenses
increase, our results of operations may be more significantly impacted by
fluctuations in the exchange rates of the currencies in which we do business.
If an adverse 10% foreign currency exchange rate change was applied to total net
monetary assets and liabilities denominated in currencies other than the local
currencies as of March 31, 2021, it would not have had a material impact on our
consolidated financial statements.
Investment and Interest Rate Risk
We are exposed to interest rate risk related primarily to our investment
portfolio and outstanding debt. Changes in interest rates affect the interest
earned on our total cash, cash equivalents, and marketable securities and the
fair value of those securities, as well as interest paid on our debt.
We had cash and cash equivalents of $4.5 billion and marketable securities of
$2.1 billion as of March 31, 2021, which consisted of corporate debt securities,
mutual funds, highly-liquid debt instruments of the U.S. government and its
agencies, and certificates of deposit. As of March 31, 2021, we had an
additional $4.0 billion that we held for bookings in advance of guests
completing check-ins, which we record separately on our condensed consolidated
balance sheets as funds receivable and amounts held on behalf of customers. The
primary objective of our investment activities is to preserve capital and meet
liquidity requirements without significantly increasing risk. We invest
primarily in highly-liquid, investment grade debt securities, and we limit the
amount of credit exposure to any one issuer. We do not enter into investments
for trading or speculative purposes and have not used any derivative financial
instruments to manage our interest rate risk exposure. Because our cash
equivalents and marketable securities generally have short maturities, the fair
value of our portfolio is relatively insensitive to interest rate fluctuations.
Due to the short-term nature of our investments, we have not been exposed to,
nor do we anticipate being exposed to, material risks due to changes in interest
rates. A hypothetical 100 basis points increase or decrease in interest rates
would not have had a material impact on our consolidated financial statements as
of March 31, 2021.
As we repaid our floating-rate loans, subject to LIBOR floors, totaling $1,995.0
million in March 2021, we are no longer exposed to the risk related to
fluctuations in interest rates to the extent LIBOR exceeds the floors.
