The following discussion should be read in conjunction with the financial
statements and notes thereto appearing elsewhere in this report.
Forward-Looking Statements
This Annual Report on Form 10-K, including the documents incorporated by
reference, contain forward-looking statements within the meaning of the federal
securities laws, Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended. We intend these
forward-looking statements to be covered by the safe harbor provisions for
forward-looking statements contained in the Private Securities Litigation Reform
Act of 1995 and are including this statement for purposes of complying with
those safe harbor provisions, in each case, to the extent applicable. Such
statements are contained principally, but not only, under the captions
"Business-Business and Growth Strategies," "Risk Factors" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations." We
caution investors that any such forward-looking statements are based on current
beliefs or expectations of future events and on assumptions made by, and
information currently available to, our management. When used, the words
"anticipate," "believe," "budget," "estimate," "expect," "intend," "may,"
"might," "plan," "project," "should," "will" and similar expressions that do not
relate solely to historical matters are intended to identify forward-looking
statements. Such statements are subject to risks, uncertainties and assumptions
and are not guarantees of future performance or occurrences, which may be
affected by known and unknown risks, trends, uncertainties and factors that are,
in some cases, beyond our control. Should one or more of these known or unknown
risks or uncertainties materialize, or should underlying assumptions prove
incorrect, actual results may vary materially from those expressed or implied by
the forward-looking statements. We caution you that, while forward-looking
statements reflect our good-faith beliefs when we make them, they are not
guarantees of future performance or occurrences and are impacted by actual
events when they occur after we make such statements. Accordingly, investors
should use caution in relying on forward-looking statements, which are based on
results and trends at the time they are made, to anticipate future results or
trends.
One of the most significant factors that may cause actual results to differ
materially from those expressed or implied by the forward-looking statements is
the ongoing impact of the global COVID-19 pandemic on the U.S. and global
economies, which has impacted, and is likely to continue to impact, us and,
directly or indirectly, many of the other important factors below and the risks
set forth in this Form 10-K in Part I, Item 1A.
Some of the risks and uncertainties that may cause our actual results,
performance or achievements to differ materially from those expressed or implied
by forward-looking statements include, among others, the following:
•the risks and uncertainties related to the impact of the COVID-19 global
pandemic, including the duration, scope and severity of the pandemic
domestically and internationally; federal, state and local government actions or
restrictive measures implemented in response to COVID-19, the effectiveness of
such measures, as well as the effect of any relaxation of current restrictions,
and the direct and indirect impact of such measures on our and our tenants'
businesses, financial condition, results of operations, cash flows, liquidity
and performance, and the U.S. and international economy and economic activity
generally; the speed, effectiveness and distribution of vaccines, whether new or
existing actions and measures continue to result in increasing unemployment that
impacts the ability of our residential tenants to generate sufficient income to
pay, or make them unwilling to pay rent in a timely manner, in full or at all;
the health, continued service and availability of our personnel, including our
key personnel and property management teams; and the effectiveness or lack of
effectiveness of governmental relief in providing assistance to individuals and
large and small businesses, including our tenants, that have suffered
significant adverse effects from COVID-19;
•volatile or adverse global economic and political conditions, health crises and
dislocations in the credit markets could adversely affect our access to
cost-effective capital and have a resulting material adverse effect on our
business opportunities, results of operations and financial condition;
•general risks affecting the real estate industry (including, without
limitation, the inability to enter into or renew leases, tenant space
utilization, dependence on tenants' financial condition, and competition from
other developers, owners and operators of real estate);
•failure to manage effectively our growth and expansion into new markets and
sub-markets or to integrate acquisitions and developments successfully;
•the ability of our joint venture partners to satisfy their obligations;

•risks and uncertainties affecting property development and construction
(including, without limitation, construction delays, increased construction
costs, cost overruns, inability to obtain necessary permits, tenant accounting
considerations that may result in negotiated lease provisions that limit a
tenant's liability during construction, and public opposition to such
activities);
•risks associated with the availability and terms of financing and the use of
debt to fund acquisitions and developments or refinance existing indebtedness,
including the impact of higher interest rates on the cost and/or availability of
financing;
•risks associated with forward interest rate contracts and the effectiveness of
such arrangements;

The risks set forth above are not exhaustive. Other sections of this report,
including "Part I, Item 1A-Risk Factors," include additional factors that could
adversely affect our business and financial performance. Moreover, we operate in
a very competitive and rapidly changing environment, particularly in light of
the circumstances relating to COVID-19. New risk factors emerge from time to
time and it is not possible for management to predict all risk factors, nor can
we assess the impact of all risk factors on our business or the extent to which
any factor, or combination of factors, may cause actual results to differ
materially from those contained in any forward-looking statements. Given these
risks and uncertainties, investors should not place undue reliance on
forward-looking statements as a prediction of actual results. Investors should
also refer to our Quarterly Reports on Form 10-Q for future periods and Current
Reports on Form 8-K as we file them with the SEC, and to other materials we may
furnish to the public from time to time through Current Reports on Form 8-K or
otherwise, for a discussion of risks and uncertainties that may cause actual
results, performance or achievements to differ materially from those expressed
or implied by forward-looking statements. We expressly disclaim any
responsibility to update any forward-looking statements to reflect changes in
underlying assumptions or factors, new information, future events, or otherwise,
and you should not rely upon these forward-looking statements after the date of
this report.
Overview
BXP is one of the largest publicly-traded office real estate investment trusts
(REITs) (based on total market capitalization as of December 31, 2020) in the
United States that develops, owns and manages primarily Class A office
properties. Our properties are concentrated in five markets in the United States
- Boston, Los Angeles, New York, San Francisco and Washington, DC. BPLP is the
entity through which BXP conducts substantially all of its business and owns
(either directly or through subsidiaries) substantially all of its assets. We
generate revenue and cash primarily by leasing Class A office space to our
tenants. When making leasing decisions, we consider, among other things, the
creditworthiness of the tenant and the industry in which it conducts business,
the length of the lease, the rental rate to be paid at inception and throughout
the lease term, the costs of tenant improvements, free rent period and other
landlord concessions, anticipated operating expenses and real estate taxes,
current and anticipated vacancy in our properties and the market overall
(including sublease space), current and expected future demand for the space,
the impact of any expansion rights and general economic factors.

Our core strategy has always been to develop, acquire and manage high-quality
properties in supply-constrained markets with high barriers-to-entry and to
focus on executing long-term leases with financially strong tenants. Our tenant
base is diverse across market sectors and the weighted-average lease term for
our in-place leases, excluding residential units, was approximately 7.4 years,
as of December 31, 2020, including leases signed by our unconsolidated joint
ventures. The weighted-average lease term for our top 20 office tenants was
approximately 10.4 years as of December 31, 2020. Historically, these factors
have minimized our exposure in weaker economic cycles and enhanced revenues as
market conditions improve. To be successful in any leasing environment, we
believe we must consider all aspects of the tenant-landlord relationship. In
this regard, we believe that our competitive advantage is based on the following
attributes:
•our understanding of tenants' short- and long-term space utilization and
amenity needs in the local markets;
•our reputation as a premier developer, owner and manager of primarily Class A
office properties;
•our financial strength and our ability to maintain high building standards;
•our focus on developing and operating in a sustainable and responsible manner;
and
•our relationships with local brokers.
Outlook
Starting in March 2020, the COVID-19 pandemic negatively impacted global
macroeconomic conditions. Following a drop in U.S. GDP of 31% in the second
quarter of 2020, GDP growth in each of the third and fourth quarters of 2020
showed sequential quarterly improvements after the enactment of federal stimulus
programs. While initial estimates indicate that GDP grew 4% in the fourth
quarter of 2020, this was a decline from the third quarter as many of the
stimulus programs began to expire toward the end of the year. U.S. stocks rose
in November of 2020 as news about vaccine efficacy provided optimism. As we
begin 2021, the U.S. economic recovery remains slow and operating conditions for
several sectors, including commercial real estate, continue to be negatively
impacted by the pandemic. The health of the overall economy and employment
trends among professional workers have been, and we expect will continue to be,
important drivers of office market conditions as vaccine distribution and
efficacy drives a return to normal.
Late in the first quarter of 2020, public health officials and governmental
authorities, including those in all of the markets in which we operate, reacted
to the spread of the COVID-19 pandemic by imposing various regulatory measures,
including quarantines, travel restrictions, issuing "stay-at-home" orders,
restricting the types of businesses that could continue to operate (including
the types of construction projects that could proceed), closing schools and
otherwise limiting the size of gatherings. Although the state and local
authorities in many of our regions eased those regulations in the second half of
2020 to allow for the return to work, the physical occupancy of our properties
remained well below capacity for the remainder of 2020 as infection rates
increased and most employers continued their COVID-19 response protocols and
encouraged employees to work from home when possible.
The future impact of the pandemic on the demand for office space is unclear as
companies consider the recessionary impact on their business and their demand
for labor while, at the same time, evaluate their space requirements in light of
their current and projected headcounts and the continued focus on social
distancing and employees' desire for more flexibility to work from home. Real
estate is by nature a long-term business and we do not believe these
considerations and ultimate decisions by tenants will evidence a clear trend in
the short term. In the meantime, we believe our strategically located, high
quality office properties will continue to be a component of today's
forward-thinking organizations that desire collaboration, innovation,
productivity and culture, and we expect tenants will take advantage of the
availability of Class A space and upgrade.
In the fourth quarter of 2020, we signed approximately 1.2 million square feet
of new leases and renewals with a weighted-average lease term of approximately
eight years, indicating that, despite headwinds, many prospective and existing
tenants continue to commit to the long-term use of space and view our properties
as their preferred choice for a premium Class A office environment. Included in
our fourth quarter 2020 leasing activity were (1) an approximately 196,000
square foot, 20-year lease for the U.S. headquarters of a multinational
automotive company at our Reston Next development in Reston, Virginia; (2) an
approximately 138,000 square-foot, 10-year lease with a biotechnology company at
200 West Street in Waltham, Massachusetts and (3) an approximately 75,000
square-foot, seven-year lease with a leading healthcare technology company at 20
CityPoint, a development in Waltham, Massachusetts that we fully placed-in
service in June 2020.

While the volume of leasing in the fourth quarter of 2020 was an improvement of
approximately 350,000 square feet of leasing from the third quarter of 2020, new
leasing activity in the fourth quarter of 2020 remained lower than it was prior
to the COVID-19 pandemic as many existing and prospective tenants deferred
decisions on their office space needs as they focused on their employees' safety
and managing their businesses through the recession and economic recovery.
The development of primarily pre-leased properties in supply-constrained markets
with the strongest economic growth over time continues to be a cornerstone of
our long-term growth strategy. As of December 31, 2020, we had approximately 3.7
million square feet of active developments and redevelopments in our pipeline,
which are 87% pre-leased, as of February 22, 2021, to predominately
credit-strong tenants with long-lease terms. Our development projects are
projected to meet required delivery milestones as defined in our leases.
The health and safety of our employees, tenants, service providers and visitors
continue to be our highest priorities. In the fourth quarter of 2020, we
continued to operate in accordance with our health safety protocols in all
in-service properties across our portfolio to provide a healthy and safe
environment in accordance with the policies and applicable legal requirements in
our regions.
Rent Collections
Cash rent payments for a particular month are generally due on the first day of
that month (although tenants have varying grace periods). Our reported rent
collection amounts are based on the total amount of rent billed by us, including
all amounts from consolidated operations and all unconsolidated joint ventures,
other than Gateway Commons, our residential properties and one hotel for which
we do not handle billing.
During the fourth quarter of 2020, our rent collections as a percentage of the
total amounts billed to all tenants were 99.1%.
•Approximately 96.2% of the total amounts billed were made to office tenants.
Our fourth quarter rent collections from office tenants continued to be strong
at 99.7%. Approximately 91.4% of our lease revenue in the fourth quarter of 2020
was generated by our office portfolio. Our office portfolio has long-term lease
contracts and modest rollover exposure over the next few years.
•Approximately 3.8% of the total amounts billed related to retail leases. Our
fourth quarter rent collections from retail tenants were 84.6%.
Revenue
As a result of the impact of the COVID-19 pandemic on the current economic
environment and on the commercial real estate sector in particular, our fourth
quarter 2020 revenues, when compared to fourth quarter 2019, continued to be
adversely affected due to (1) write-offs of accrued rent balances, (2) declines
in revenue from our retail tenants, parking and our single hotel, and (3) a
decline in occupancy in our in-service office and retail properties due to a
slowdown in new leasing activity for vacant and expiring space.
When evaluating the collectability of a tenant's accrued rent and accounts
receivable balances, management analyzes the tenant's creditworthiness, current
economic trends, including the impact of COVID-19 on a tenant's business, and
changes in the tenant's payment patterns on a lease-by-lease basis. In the
fourth quarter of 2020, we recorded write-offs totaling approximately $40.1
million, of which approximately $39.8 million were primarily associated with the
write-off of accrued rent of all tenants in the co-working sector and
approximately $0.3 million were associated with accounts receivable. These
amounts represent the write-offs in our consolidated portfolio, plus our share
of the write-offs from the unconsolidated joint ventures (calculated based on
our ownership percentage), minus our partners' share of write-offs from our
consolidated joint ventures (calculated based upon the partners' percentage
ownership interests). We will recognize lease revenue from tenants in the
co-working sector on a cash basis commencing in the first quarter of 2021.
Our retail tenants were materially and adversely affected by the COVID-19
pandemic in 2020. Lease revenue from our retail leases was approximately $46.7
million in the fourth quarter of 2020, a $6.3 million, or 12.0%, decrease
compared to $53.0 million during the fourth quarter of 2019.

In the fourth quarter of 2020, our parking and other revenue was approximately
$15.9 million, representing a small decrease compared to $16.3 million of
parking and other revenue in the third quarter of 2020, but a decrease of
approximately $10.8 million, or 40%, compared to the fourth quarter of 2019. The
year-over-year decline was largely due to the decline in transient parking
revenue as employees continue to work from home amid safety concerns during the
pandemic.
Our hotel property, the Boston Marriott Cambridge, re-opened in October 2020 but
operated at diminished occupancy and generated only $0.5 million in revenue in
the fourth quarter of 2020. Although this was an improvement from the third
quarter of 2020 when the hotel was closed, our hotel revenue in the fourth
quarter of 2020 decreased $11.3 million as compared to the fourth quarter of
2019. We expect hotel occupancy to remain low until a sufficient number of
people have been vaccinated and the demand for travel and leisure returns to
historical levels.
The overall occupancy of our in-service office and retail properties was 90.1%
at December 31, 2020, a decrease of 290 basis points compared to 93.0% at
December 31, 2019. The decrease was primarily due to fully placing in-service
Dock 72, an approximately 669,000 square foot office property located in
Brooklyn, New York in which we have a 50% ownership interest, which was only 33%
leased, as of December 31, 2020, and a slowdown of leasing activity for
available space.
Despite the concerns of the COVID-19 pandemic and the negative impact on
economic conditions in our markets, we continue to be optimistic for our
industry generally and our company in particular, given low interest rates, the
high quality of our properties, the supply demand characteristics of our markets
and the success of our development efforts. In addition, we anticipate our
revenue from retail, parking and our hotel to improve as the pandemic subsides.
As a leading developer, owner and manager of marquee Class A office properties
in the United States, our priorities remain focused on the following:
•ensuring tenant health, safety and satisfaction;
•leasing available space in our in-service and development properties, as well
as proactively focusing on future lease expirations;
•completing the construction of our development properties;
•continuing and completing the redevelopment and repositioning of several key
properties to increase future revenue and asset values over the long-term;
•maintaining discipline in our underwriting of investment opportunities;
•managing our near-term debt maturities and maintaining our conservative balance
sheet; and
•actively managing our operations in a sustainable and responsible manner.
The following is an overview of portfolio activity and leasing activity in the
fourth quarter and full year 2020.
During the fourth quarter of 2020, we signed leases across our portfolio
totaling approximately 1.2 million square feet and we commenced revenue
recognition on approximately 935,000 square feet of leases in second generation
space, including lease renewals. Of these second generation leases,
approximately 869,000 square feet had been vacant for less than one year and, in
the aggregate, they represent an increase in net rental obligations (gross rent
less operating expenses) of approximately 11% over the prior leases.
Consistent with our long-term investment strategy to invest in high-yielding
development opportunities, in 2020, we completed and fully placed in-service
approximately 1.8 million square feet of new development, including two office
development properties that are each approximately 100% leased, including leases
with future commencement dates: 17Fifty Presidents Street, an approximately
276,000 square foot property in Reston, Virginia, and 20 CityPoint, an
approximately 211,000 square foot property in Waltham, Massachusetts. We also
fully placed in-service Dock 72, an approximately 669,000 square foot office
property located in Brooklyn, New York in which we have a 50% ownership
interest, which was 33% leased as of December 31, 2020. In addition, during 2020
we fully placed in-service two residential properties: Hub50House, a 440 unit
residential property in Boston, Massachusetts in which we have a 50% ownership
interest, and The Skylyne, a 402 unit residential property in Oakland,
California.
                                       61
--------------------------------------------------------------------------------
  Table of Contents
As of December 31, 2020, our construction/redevelopment pipeline consisted of
six properties that, when completed, we expect will total approximately 3.7
million net rentable square feet. Three of these development/redevelopment
projects are owned by joint ventures. Our share of the estimated total cost for
these projects is approximately $2.2 billion, of which approximately $849
million remains to be invested as of December 31, 2020. Approximately 87% of the
commercial space in these development projects was pre-leased as of February 22,
2021.
As we continue to focus on the development and acquisition of assets to enhance
our long-term growth, we also continually review our portfolio to identify
properties as potential sales candidates that either no longer fit within our
portfolio strategy or could attract premium pricing in the current market
environment. For example, during 2020, we completed the sale of several
properties and land parcels for aggregate net proceeds of $537.7 million (our
share), including New Dominion Technology Park in Herndon, Virginia;
approximately 455,000 square feet of Capital Gallery in Washington, DC;
Annapolis Junction Building Eight and two parcels of land at Annapolis Junction
Business Park in Annapolis, Maryland and a land parcel in Marlborough,
Massachusetts. We expect to continue to sell select assets from time to time,
subject to market conditions.
A brief overview of each of our markets follows.
Boston
Our Boston central business district ("CBD") in-service portfolio was
approximately 98% leased as of December 31, 2020. This includes approximately
225,000 square feet of retail leases, representing 2.3% of our Boston CBD
portfolio, that we terminated due to the nonpayment of rent, but where the
tenants have yet to vacate. During the fourth quarter of 2020, we executed
approximately 451,000 square feet of leases and had approximately 171,000 square
feet of leases commenced in the Boston region. Approximately 163,000 square feet
of the leases that commenced had been vacant for less than one year and
represent an increase in net rental obligations of approximately 54% over the
prior leases.
Our approximately 2.0 million square foot in-service office portfolio in
Cambridge was approximately 99% leased as of December 31, 2020. During the
fourth quarter of 2020, we continued our development of 325 Main Street at
Kendall Center in Cambridge, Massachusetts, which is 90% pre-leased to an office
tenant for a term of 15 years and we expect to deliver into service in 2022.
Waltham and the area surrounding the Route 128-Mass Turnpike interchange
continue to comprise a popular submarket of Boston for leading and emerging
companies in the life sciences, biotechnology and technology sectors. In our
suburban portfolio, we continued the redevelopment of 200 West Street, an
approximately 273,000 square feet Class A office property in Waltham,
Massachusetts. The redevelopment is a conversion of approximately 138,000 square
feet into life sciences space to meet growing demand in the life sciences
sector. In the fourth quarter of 2020, we signed a 10-year lease with a new
tenant for this life sciences space with occupancy expected by year-end 2021.
With this lease, the property, including the office space, is approximately 100%
leased. During the fourth quarter of 2020, we also signed a new 75,000
square-foot, seven-year lease with a leading healthcare technology company at 20
CityPoint, a Class A office property that was fully placed in-service in 2020.
With this lease, the office portion of the property is 100% leased.
Additionally, in the third quarter of 2020, we entered into an agreement with an
existing joint venture partner for the future development of a 1.2 million
square foot site in Waltham. The agreement allows for the phased development of
office and life sciences properties across 41-acres and builds on our current
footprint of approximately 4.3 million square feet of office and life sciences
properties in this submarket.
Los Angeles
Our Los Angeles ("LA") in-service portfolio of approximately 2.3 million square
feet is currently focused on West LA and includes Colorado Center, a 1.1 million
square foot property of which we own 50%, and Santa Monica Business Park, a
21-building, approximately 1.2 million square foot property of which we own 55%.
As of December 31, 2020, our LA in-service properties were approximately 94%
leased.
We continue to explore opportunities to increase our presence by seeking
investments where our financial, operational, redevelopment and development
expertise provide the opportunity, either alone or with partners, to achieve
accretive returns. In the third quarter of 2020, we acquired a 50% ownership
interest in Beach Cities Media Campus, a 6.4-acre land site on the Rosecrans
Corridor of the El Segundo submarket of Los Angeles. The site is fully entitled
to support the future development of approximately 275,000 square feet of Class
A creative office

space and is located in the South Bay of Los Angeles, a creative cluster where
several Fortune 500 and emerging office tenants in the technology, entertainment
and financial sectors are located.
New York
As of December 31, 2020, our New York CBD in-service portfolio was approximately
90% leased. In addition, we executed approximately 93,000 square feet of leases
and approximately 264,000 square feet of leases commenced in the fourth quarter
of 2020. Of these leases, approximately 239,000 square feet had been vacant for
less than one year and represent an increase in net rental obligations of
approximately 12% over the prior leases.
In the fourth quarter of 2020, we fully placed in-service Dock 72, an
unconsolidated joint venture development located in Brooklyn, New York in which
we own a 50% interest. The property consists of approximately 669,000 square
feet of Class A office space and was 33% leased as of December 31, 2020.
Excluding Dock 72, the remainder of the New York CBD in-service portfolio is
approximately 94% leased. We recognized a $60.5 million non-cash impairment
charge related to our investment in Dock 72 due to an increase in construction
costs and an extension of the projected period to fully lease the property due
to the COVID-19 pandemic, resulting in a lower current fair value.
San Francisco
In the fourth quarter of 2020, governmental authorities in San Francisco
extended travel quarantines, stay-at-home orders and restrictions on the types
of businesses that could continue to operate, including offices, except for
non-essential workers, which impacted the pace of new leasing activity.
Our San Francisco CBD in-service properties were approximately 95% leased as of
December 31, 2020. During the fourth quarter of 2020, we executed approximately
67,000 square feet of leases and we commenced approximately 50,000 square feet
of leases in the San Francisco region. Of these leases, approximately 39,000
square feet had been vacant for less than one year and represent an increase in
net rental obligations of approximately 22% over the prior leases.
Washington, DC
In the Washington, DC region, we remain focused on (1) expanding our development
potential in Reston, Virginia, where demand from technology and cybersecurity
tenants remains strong, (2) divesting of certain assets in Washington, DC and
select suburban markets and (3) matching development sites with tenants to begin
development with significant pre-leasing commitments. During the fourth quarter
of 2020, we executed approximately 547,000 square feet of leases and we
commenced approximately 229,000 square feet of leases in the Washington, DC
region. Of these leases, approximately 207,000 square feet had been vacant for
less than one year.
Our Washington, DC CBD in-service properties were approximately 84% leased, as
of December 31, 2020, with modest near-term exposure, and we have reduced our
exposure in the Washington, DC CBD market significantly over the past few years
through the dispositions of assets.
Our Washington, DC suburban properties, which includes our significant presence
in Reston, Virginia, were approximately 85% leased as of December 31, 2020.
During the fourth quarter of 2020, we signed an approximately 196,000 square
foot, 20-year lease with a tenant at Reston Next, our approximately 1.1 million
square foot development, the new phase of Reston Town Center in Reston,
Virginia. With this lease, the Reston Next development is 85% pre-leased, as of
February 22, 2021, and we expect to place this property in-service in 2022.

Critical Accounting Policies
The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America, or GAAP, requires management
to use judgment in the application of accounting policies, including making
estimates and assumptions. We base our estimates on historical experience and on
various other assumptions believed to be reasonable under the circumstances.
These judgments affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the financial
statements and the reported amounts of revenue and expenses during the reporting
periods. If our judgment or interpretation of the facts and circumstances
relating to various transactions had been different, it is possible that
different accounting policies would have been applied resulting in a different
presentation of our financial statements. From time to time, we evaluate our
estimates and assumptions. In the event estimates or assumptions prove to be
different from actual results, adjustments are made in subsequent periods to
reflect more current information. Below is a discussion of accounting policies
that we consider critical in that they may require complex judgment in their
application or require estimates about matters that are inherently uncertain.
Real Estate
Upon acquisitions of real estate, we assess whether the transaction should be
accounted for as an asset acquisition or as a business combination by applying a
screen to determine whether the integrated set of assets and activities acquired
meets the definition of a business. Acquisitions of integrated sets of assets
and activities that do not meet the definition of a business are accounted for
as asset acquisitions. Our acquisitions of real estate or in-substance real
estate generally will not meet the definition of a business because
substantially all of the fair value is concentrated in a single identifiable
asset or group of similar identifiable assets (i.e. land, buildings, and related
intangible assets) or because the acquisition does not include a substantive
process in the form of an acquired workforce or an acquired contract that cannot
be replaced without significant cost, effort or delay.
We assess the fair value of acquired tangible and intangible assets (including
land, buildings, tenant improvements, "above-" and "below-market" leases,
leasing and assumed financing origination costs, acquired in-place leases, other
identified intangible assets and assumed liabilities) and allocate the purchase
price to the acquired assets and assumed liabilities, including land and
buildings as if vacant. We assess fair value based on estimated cash flow
projections that utilize discount and/or capitalization rates that we deem
appropriate, as well as available market information. Estimates of future cash
flows are based on a number of factors including the historical operating
results, known and anticipated trends, and market and economic conditions.
The fair value of the tangible assets of an acquired property considers the
value of the property as if it were vacant. We also consider an allocation of
purchase price of other acquired intangibles, including acquired in-place leases
that may have a customer relationship intangible value, including (but not
limited to) the nature and extent of the existing relationship with the tenants,
the tenants' credit quality and expectations of lease renewals. Based on our
acquisitions to date, our allocation to customer relationship intangible assets
has been immaterial.
We record acquired "above-" and "below-market" leases at their fair values
(using a discount rate which reflects the risks associated with the leases
acquired) equal to the difference between (1) the contractual amounts to be paid
pursuant to each in-place lease and (2) management's estimate of fair market
lease rates for each corresponding in-place lease, measured over a period equal
to the remaining term of the lease for above-market leases and the initial term
plus the term of any below-market fixed rate renewal options for below-market
leases. Acquired "above-" and "below-market" lease values have been reflected
within Prepaid Expenses and Other Assets and Other Liabilities, respectively, in
our Consolidated Balance Sheets. Other intangible assets acquired include
amounts for in-place lease values that are based on our evaluation of the
specific characteristics of each tenant's lease. Factors to be considered
include estimates of carrying costs during hypothetical expected lease-up
periods considering current market conditions, and costs to execute similar
leases. In estimating carrying costs, we include real estate taxes, insurance
and other operating expenses and estimates of lost rentals at market rates
during the expected lease-up periods, depending on local market conditions. In
estimating costs to execute similar leases, we consider leasing commissions,
legal and other related expenses.

Management reviews its long-lived assets for indicators of impairment following
the end of each quarter and when events or changes in circumstances indicate
that the carrying amount of the asset may not be recoverable. This evaluation of
long-lived assets is dependent on a number of factors, including when there is
an event or adverse change in the operating performance of the long-lived asset
or a current expectation that, more likely than not, a long-lived asset will be
sold or otherwise disposed of significantly before the end of its previously
estimated useful life or hold period. An impairment loss is recognized if the
carrying amount of an asset is not recoverable and exceeds its fair value. The
evaluation of anticipated cash flows is subjective and is based in part on
assumptions regarding anticipated hold periods, future occupancy, future rental
rates, future capital requirements, discount rates and capitalization rates that
could differ materially from actual results in future periods. Because cash
flows on properties considered to be "long-lived assets to be held and used" are
considered on an undiscounted basis to determine whether an asset may be
impaired, our established strategy of holding properties over the long term
directly decreases the likelihood of recording an impairment loss. If our hold
strategy changes or market conditions otherwise dictate an earlier sale date, an
impairment loss may be recognized and such loss could be material. If we
determine that an impairment has occurred, the affected assets must be reduced
to their fair value.
Guidance in Accounting Standards Codification ("ASC") 360 "Property Plant and
Equipment" requires that qualifying assets and liabilities and the results of
operations that have been sold, or otherwise qualify as "held for sale," be
presented as discontinued operations in all periods presented if the property
operations are expected to be eliminated and we will not have significant
continuing involvement following the sale. Discontinued operations presentation
applies only to disposals representing a strategic shift that has (or will have)
a major effect on an entity's operations and financial results (e.g., a disposal
of a major geographical area, a major line of business, a major equity method
investment or other major parts of an entity). The components of the property's
net income that are reflected as discontinued operations include the net gain
(or loss) upon the disposition of the property held for sale, operating results,
depreciation and interest expense (if the property is subject to a secured
loan). We generally consider assets to be "held for sale" when the transaction
has been approved by BXP's Board of Directors, or a committee thereof, and there
are no known significant contingencies relating to the sale, such that a sale of
the property within one year is considered probable. Following the
classification of a property as "held for sale," no further depreciation is
recorded on the assets, and the asset is written down to the lower of carrying
value or fair market value, less cost to sell.
Real estate is stated at depreciated cost. A variety of costs are incurred in
the acquisition, development and leasing of properties. The cost of buildings
and improvements includes the purchase price of property, legal fees and other
acquisition costs. We capitalize acquisition costs that we incur to effect an
asset acquisition and expense acquisition costs that we incur to effect a
business combination, including legal, due diligence and other closing related
costs. Costs directly related to the development of properties are capitalized.
Capitalized development costs include interest, internal wages, property taxes,
insurance, and other project costs incurred during the period of development.
After the determination is made to capitalize a cost, it is allocated to the
specific component of the project that benefited from the investment.
Determination of when a development project commences and capitalization begins,
and when a development project is substantially complete and held available for
occupancy and capitalization must cease, involves a degree of judgment. Our
capitalization policy on development properties follows the guidance in ASC
835-20 "Capitalization of Interest" and ASC 970 "Real Estate-General." The costs
of land and buildings under development include specifically identifiable costs.
Capitalized costs include pre-construction costs necessary to the development of
the property, development costs, construction costs, interest costs, real estate
taxes, salaries and related costs and other costs incurred during the period of
development. We begin the capitalization of costs during the pre-construction
period, which we define as activities that are necessary for the development of
the property. We consider a construction project as substantially complete and
held available for occupancy upon the completion of tenant improvements, but no
later than one year from cessation of major construction activity. We cease
capitalization on the portion (1) substantially completed, (2) occupied or held
available for occupancy, and capitalize only those costs associated with the
portion under construction or (3) if activities necessary for the development of
the property have been suspended.
Investments in Unconsolidated Joint Ventures
We consolidate variable interest entities ("VIEs") in which we are considered to
be the primary beneficiary. VIEs are entities in which the equity investors do
not have sufficient equity at risk to finance their endeavors without additional
financial support or that the holders of the equity investment at risk do not
have substantive participating rights. The primary beneficiary is defined by the
entity having both of the following characteristics: (1) the power to direct the
activities that, when taken together, most significantly impact the variable
interest entity's performance, and (2) the obligation to absorb losses and the
right to receive the returns from the variable interest entity that could
                                       66
--------------------------------------------------------------------------------
  Table of Contents
potentially be significant to the VIE. For ventures that are not VIEs, we
consolidate entities for which we have significant decision making control over
the ventures' operations. Our judgment with respect to our level of influence or
control of an entity involves the consideration of various factors including the
form of our ownership interest, our representation in the entity's governance,
the size of our investment (including loans), estimates of future cash flows,
our ability to participate in policy making decisions and the rights of the
other investors to participate in the decision making process and to replace us
as manager and/or liquidate the venture, if applicable. Our assessment of our
influence or control over an entity affects the presentation of these
investments in our consolidated financial statements. In addition to evaluating
control rights, we consolidate entities in which the outside partner has no
substantive kick-out rights to remove us as the managing member.
Accounts of the consolidated entity are included in our accounts and the
noncontrolling interest is reflected on the Consolidated Balance Sheets as a
component of equity or in temporary equity between liabilities and equity.
Investments in unconsolidated joint ventures are recorded initially at cost, and
subsequently adjusted for equity in earnings and cash contributions and
distributions. Any difference between the carrying amount of these investments
on the balance sheet and the underlying equity in net assets is amortized as an
adjustment to equity in earnings of unconsolidated joint ventures over the life
of the related asset. Under the equity method of accounting, our net equity
investment is reflected within the Consolidated Balance Sheets, and our share of
net income or loss from the joint ventures is included within the Consolidated
Statements of Operations. The joint venture agreements may designate different
percentage allocations among investors for profits and losses; however, our
recognition of joint venture income or loss generally follows the joint
venture's distribution priorities, which may change upon the achievement of
certain investment return thresholds. We may account for cash distributions in
excess of our investment in an unconsolidated joint venture as income when we
are not the general partner in a limited partnership and when we have neither
the requirement nor the intent to provide financial support to the joint
venture. We classify distributions received from equity method investees within
our Consolidated Statements of Cash Flows using the nature of the distribution
approach, which classifies the distributions received on the basis of the nature
of the activity or activities of the investee that generated the distribution as
either a return on investment (classified as cash inflows from operating
activities) or a return of investment (classified as cash inflows from investing
activities). Our investments in unconsolidated joint ventures are reviewed for
indicators of impairment on a quarterly basis and we record impairment charges
when events or circumstances change indicating that a decline in the fair values
below the carrying amounts has occurred and such decline is
other-than-temporary. This evaluation of the investments in unconsolidated joint
ventures is dependent on a number of factors, including the performance of each
investment and market conditions. We will record an impairment charge if we
determine that a decline in the fair value below the carrying amount of an
investment in an unconsolidated joint venture is other-than-temporary. The fair
value is calculated using discounted cash flows which is subjective and
considers assumptions regarding future occupancy, future rental rates, future
capital requirements, discount rates and capitalization rates that could differ
materially from actual results in future periods.
To the extent that we contribute assets to a joint venture, our investment in
the joint venture is recorded at our cost basis in the assets that were
contributed to the joint venture. To the extent that our cost basis is different
than the basis reflected at the joint venture level, the basis difference is
amortized over the life of the related asset and included in our share of equity
in net income of the joint venture. In accordance with the provisions of ASC
610-20 "Gains and Losses from the Derecognition of Nonfinancial Assets" ("ASC
610-20"), we will recognize a full gain on both the retained and sold portions
of real estate contributed or sold to a joint venture by recognizing our new
equity method investment interest at fair value.
The combined summarized financial information of the unconsolidated joint
ventures is disclosed in Note 6 to the Consolidated Financial Statements.
Revenue Recognition
In general, we commence lease/rental revenue recognition when the tenant takes
possession of the leased space and the leased space is substantially ready for
its intended use. Contractual lease/rental revenue is reported on a
straight-line basis over the terms of the respective leases. We recognize
acquired in-place "above-" and "below-market" leases at their fair values as
lease/rental revenue over the original term of the respective leases. Accrued
rental income as reported on the Consolidated Balance Sheets represents
cumulative lease/rental income earned in excess of rent payments received
pursuant to the terms of the individual lease agreements.
For the year ended December 31, 2020, the impact of the net adjustments of rents
from "above-" and "below-market" leases increased lease revenue by approximately
$6.5 million. For the year ended December 31, 2020, the impact of the
straight-line rent adjustment increased lease revenue by approximately $104.9
million. Those
                                       67

amounts exclude the adjustment of rents from "above-" and "below-market" leases
and straight-line income from unconsolidated joint ventures, which are disclosed
in Note 6 to the Consolidated Financial Statements.
Our leasing strategy is generally to secure creditworthy tenants that meet our
underwriting guidelines. Furthermore, following the initiation of a lease, we
continue to actively monitor the tenant's creditworthiness to ensure that all
tenant related assets are recorded at their realizable value. When assessing
tenant credit quality, we:
•review relevant financial information, including:
•financial ratios;
•net worth;
•revenue;
•cash flows;
•leverage; and
•liquidity;
•evaluate the depth and experience of the tenant's management team; and
•assess the strength/growth of the tenant's industry.
As a result of the underwriting process, tenants are then categorized into one
of three categories:
(1)acceptable-risk tenants;
(2)the tenant's credit is such that we may require collateral, in which case we:
•may require a security deposit; and/or
•may reduce upfront tenant improvement investments; or
(3)the tenant's credit is below our acceptable parameters.
We must make estimates as to the collectability of our accrued rent and accounts
receivable related to lease revenue. Management analyzes accrued rent and
accounts receivable by considering tenant creditworthiness, current economic
trends, including the impact of the novel coronavirus ("COVID-19") pandemic on
tenants' businesses, and changes in tenants' payment patterns when evaluating
the collectability of the tenant's receivable balance, including the accrued
rent receivable, on a lease-by-lease basis. We write-off the tenant's receivable
balance, including the accrued rent receivable, if we consider the balances no
longer probable of collection. In addition, tenants in bankruptcy are analyzed
and considerations are made in connection with the expected recovery of
pre-petition and post-petition claims If the balances are considered no longer
probable of collection and therefore written off, we will cease to recognize
lease income, including straight-line rent, unless cash is received. If we
subsequently determine that we are probable we will collect substantially all
the remaining lessee's lease payments under the lease term, we will then
reinstate the straight-line balance, adjusting for the amount related to the
period when the lease payments were considered not probable. If our estimate of
collectability differ from the cash received, then the timing and amount of our
reported revenue could be impacted. The credit risk is mitigated by the high
quality of our existing tenant base, reviews of prospective tenants' risk
profiles prior to lease execution and consistent monitoring of our portfolio to
identify potential problem tenants.
The weighted-average term of our in-place leases, excluding residential units,
was approximately 7.4 years, as of December 31, 2020, including leases signed by
our unconsolidated joint ventures. The credit risk is mitigated by the high
quality of our existing tenant base, reviews of prospective tenants' risk
profiles prior to lease execution and consistent monitoring of our portfolio to
identify potential problem tenants.
Recoveries from tenants, consisting of amounts due from tenants for common area
maintenance, real estate taxes and other recoverable costs, are recognized as
revenue in the period during which the expenses are incurred (See "Leases" ). We
recognize these reimbursements on a gross basis, as we obtain control of the
goods and services before they are transferred to the tenant. We also receive
reimbursements of payroll and payroll related costs from unconsolidated joint
venture entities and third party property owners in connection with management
services contracts which we reflect on a gross basis instead of on a net basis
as we have determined that we are the principal and not the agent under these
arrangements in accordance with the guidance in ASC 606 "Revenue from Contracts
with Customers" ("ASC 606").

Our parking revenue is derived primarily from monthly and transient daily
parking. In addition, we have certain lease arrangements for parking accounted
for under the guidance in ASC 842 "Leases" ("ASC 842"). The monthly and
transient daily parking revenue falls within the scope of ASC 606 and is
accounted for at the point in time when control of the goods or services
transfers to the customer and our performance obligation is satisfied.
Our hotel revenue is derived from room rentals and other sources such as charges
to guests for telephone service, movie and vending commissions, meeting and
banquet room revenue and laundry services. Hotel revenue is recognized as the
hotel rooms are occupied and the services are rendered to the hotel customers.
We earn management and development fees. Development and management services
revenue is earned from unconsolidated joint venture entities and third-party
property owners. We determined that the performance obligations associated with
our development services contracts are satisfied over time and that we would
recognize our development services revenue under the output method evenly over
time from the development commencement date through the substantial completion
date of the development management services project due to the stand-ready
nature of the contracts. Significant judgments impacting the amount and timing
of revenue recognized from our development services contracts include estimates
of total development project costs from which the fees are typically derived and
estimates of the period of time until substantial completion of the development
project, the period of time over which the development services are required to
be performed. We recognize development fees earned from unconsolidated joint
venture projects equal to its cost plus profit to the extent of the third party
partners' ownership interest. Property management fees are recorded and earned
based on a percentage of collected rents at the properties under management, and
not on a straight-line basis, because such fees are contingent upon the
collection of rents.
Gains on sales of real estate are recognized pursuant to the provisions included
in ASC 610-20. Under ASC 610-20, we must first determine whether the transaction
is a sale to a customer or non-customer. We typically sell real estate on a
selective basis and not within the ordinary course of our business and therefore
expects that our sale transactions will not be contracts with customers. We next
determine whether we have a controlling financial interest in the property after
the sale, consistent with the consolidation model in ASC 810 "Consolidation"
("ASC 810"). If we determine that we do not have a controlling financial
interest in the real estate, we evaluate whether a contract exists under ASC 606
and whether the buyer has obtained control of the asset that was sold. We
recognize a full gain on sale of real estate when the derecognition criteria
under ASC 610-20 have been met.
Leases
Lessee
For leases in which we are the lessee (generally ground leases), in accordance
with ASC 842 we recognize a right-of-use asset and a lease liability. We made
the policy election to not apply the revenue recognition requirements of ASC 842
to short-term leases. This policy election is made by class of underlying assets
and as described below, we consider real estate to be a class of underlying
assets, and will not be further delineating it into specific uses of the real
estate asset as the risk profiles are similar in nature. We will recognize the
lease payments in net income on a straight-line basis over the lease term.
The lease liability is equal to the present value of the minimum lease payments
in accordance with ASC 842. We will use our incremental borrowing rate ("IBR")
to determine the net present value of the minimum lease payments. In order to
determine the IBR, we utilized a market-based approach to estimate the
incremental borrowing rate for each individual lease. The approach required
significant judgment. Therefore, we utilized different data sets to estimate
base IBRs via an analysis of the following weighted-components:
•the interpolated rates from yields on outstanding U.S. Treasury issuances for
up to 30 years and for years 31 and beyond, longer-term publicly traded
educational institution debt issued by high credit quality educational
institutions with maturity dates exceeding 31 years,
•observable mortgage rates spread over U.S. Treasury issuances, and
•unlevered property yields and discount rates.

We then applied adjustments to account for considerations related to term and interpolated the IBR.

Lessor
We lease primarily Class A office, life sciences, retail and residential space
to tenants. These leases may contain extension and termination options that are
predominately at the sole discretion of the tenant, provided certain conditions
are satisfied. In a few instances, the leases also contain purchase options,
which would be exercisable at fair market value. Also, certain of our leases
include rental payments that are based on a percentage of the tenant sales in
excess of contractual amounts.
Per ASC 842, lessors do not need to separate nonlease components from the
associated lease component if certain criteria stated above are met for each
class of underlying assets. The guidance in ASC 842 defines "underlying asset"
as "an asset that is the subject of a lease for which a right to use that asset
has been conveyed to a lessee. The underlying asset could be a physically
distinct portion of a single asset." Based on the above guidance, we consider
real estate assets as a class of underlying assets and will not be further
delineating it into specific uses of the real estate asset as the risk profiles
are similar in nature.
Lease components are elements of an arrangement that provide the customer with
the right to use an identified asset. Nonlease components are distinct elements
of a contract that are not related to securing the use of the leased asset and
revenue is recognized in accordance with ASC 606. We consider common area
maintenance (CAM) and service income associated with tenant work orders to be
nonlease components because they represent delivery of a separate service but
are not considered a cost of securing the identified asset. In the case of our
business, the identified asset would be the leased real estate (office, life
sciences, retail or residential).
We assessed and concluded that the timing and pattern of transfer for nonlease
components and the associated lease component are the same. We determined that
the predominant component was the lease component and as such our leases will
continue to qualify as operating leases and we have made a policy election to
account for and present the lease component and the nonlease component as a
single component in the revenue section of the Consolidated Statements of
Operations labeled Lease. Prior to the January 1, 2019 adoption of ASC 842,
nonlease components had been included within Recoveries from Tenants Revenue,
Parking and Other Revenue and Development and Management Services Revenue on our
Consolidated Statements of Operations.
Recoveries from tenants, consisting of amounts due from tenants for common area
maintenance, real estate taxes and other recoverable costs, are recognized as
revenue in the period during which the expenses are incurred.
In addition, in accordance with ASC 842, lessors will only capitalize
incremental direct leasing costs. As a result, upon adoption of ASC 842 on
January 1, 2019, we no longer capitalizes non-incremental legal costs and
internal leasing wages. These costs are expensed as incurred. The expensing of
these items is included within General and Administrative Expense on the
Consolidated Statements of Operations.
Depreciation and Amortization
We compute depreciation and amortization on our properties using the
straight-line method based on estimated useful asset lives. We allocate the
acquisition cost of real estate to its components and depreciate or amortize
these assets (or liabilities) over their useful lives. The amortization of
acquired "above-" and "below-market" leases and acquired in-place leases is
recorded as an adjustment to revenue and depreciation and amortization,
respectively, in the Consolidated Statements of Operations.
Fair Value of Financial Instruments
The carrying values of cash and cash equivalents, marketable securities,
escrows, receivables, accounts payable, accrued expenses and other assets and
liabilities are reasonable estimates of their fair values because of the short
maturities of these instruments.
We follow the authoritative guidance for fair value measurements when valuing
our financial instruments for disclosure purposes The table below presents the
financial instruments that are being valued for disclosure purposes as well as
the Level at which they are categorized as defined in ASC 820 "Fair Value
Measurements and Disclosures".

(1) If trading volume for the period is low, the valuation could be categorized
as Level 2.
Because our valuations of our financial instruments are based on the above
Levels and involve the use of estimates, the actual fair values of our financial
instruments may differ materially from those estimates.
Derivative Instruments and Hedging Activities
Derivative instruments and hedging activities require management to make
judgments on the nature of its derivatives and their effectiveness as hedges.
These judgments determine if the changes in fair value of the derivative
instruments are reported in the Consolidated Statements of Operations as a
component of net income or as a component of comprehensive income and as a
component of equity on the Consolidated Balance Sheets. While management
believes its judgments are reasonable, a change in a derivative's effectiveness
as a hedge could materially affect expenses, net income and equity. We account
for both the effective and ineffective portions of changes in the fair value of
a derivative in other comprehensive income (loss) and subsequently reclassify
the fair value of the derivative to earnings over the term that the hedged
transaction affects earnings and in the same line item as the hedged transaction
within the statements of operations
Income Taxes
Boston Properties Inc.
BXP has elected to be treated as a REIT under Sections 856 through 860 of the
Internal Revenue Code of 1986, as amended (the "Code"), commencing with its
taxable year ended December 31, 1997. As a result, it generally will not be
subject to federal corporate income tax on its taxable income that is
distributed to its stockholders. A REIT is subject to a number of organizational
and operational requirements, including a requirement that it currently
distribute at least 90% of its annual taxable income (with certain adjustments).
BXP's policy is to distribute at least 100% of its taxable income. Accordingly,
the only provision for federal income taxes in the accompanying consolidated
financial statements relates to BXP's consolidated taxable REIT subsidiaries.
BXP's taxable REIT subsidiaries did not have significant tax provisions or
deferred income tax items. BXP had no uncertain tax positions recognized as of
December 31, 2020 and 2019. At December 31, 2020, BXP's tax returns for the
years 2017 forward remain subject to examination by the major tax jurisdictions
under the statute of limitations.
We own a hotel property that we lease to one of our taxable REIT subsidiaries
and that is managed by Marriott International, Inc. The hotel taxable REIT
subsidiary, a wholly owned subsidiary of BPLP, is the lessee pursuant to the
lease for the hotel property. As lessor, BPLP is entitled to a percentage of
gross receipts from the hotel property. Marriott International, Inc. continues
to manage the hotel property under the Marriott name and under terms of a
management agreement. The hotel taxable REIT subsidiary is subject to tax at the
federal and state level and, accordingly, BXP has recorded a tax provision in
its Consolidated Statements of Operations for the years ended December 31, 2020,
2019 and 2018.
The net difference between the tax basis and the reported amounts of BXP's
assets and liabilities was approximately $2.0 billion and $1.7 billion as of
December 31, 2020 and 2019, respectively, which was primarily related to the
difference in basis of contributed property and accrued rental income.
Certain entities included in BXP's Consolidated Financial Statements are subject
to certain state and local taxes. These taxes are recorded as operating expenses
in the accompanying consolidated financial statements.

Form 10-K for the year ended December 31, 2019, which was filed with the SEC on
March 2, 2020.
The impact that COVID-19 has had on our business, financial position and results
of operations during the year ended December 31, 2020 is discussed throughout
this Annual Report on Form 10-K. The full extent of the impact of COVID-19 on
our business, operations and financial results will depend on numerous evolving
factors that we may not be able to accurately predict. In addition, we cannot
predict the impact that COVID-19 will have on our tenants, employees,
contractors, lenders, suppliers, vendors and joint venture partners and any
material adverse effect on these parties could also have a material adverse
effect on us. The situation surrounding COVID-19 remains fluid, and we are
actively managing our response in collaboration with tenants, government
officials and joint venture partners and assessing potential impacts to our
financial position and operating results, as well as potential adverse
developments in our business. See Item 1A: "Risk Factors" for additional
details.

At each of December 31, 2020 and 2019, we owned or had joint venture interests
in a portfolio of 196 commercial real estate properties (in each case, the
"Total Property Portfolio"). As a result of changes within our Total Property
Portfolio, the financial data presented below shows significant changes in
revenue and expenses from period-to-period. Accordingly, we do not believe that
our period-to-period financial data with respect to the Total Property Portfolio
is meaningful. Therefore, the comparison of operating results for the years
ended December 31, 2020 and 2019 show separately the changes attributable to the
properties that were owned by us and in-service throughout each period compared
(the "Same Property Portfolio") and the changes attributable to the properties
included in the Acquired, Placed In-Service, Development or Redevelopment or
Sold Portfolios.
In our analysis of operating results, particularly to make comparisons of net
operating income between periods meaningful, it is important to provide
information for properties that were in-service and owned by us throughout each
period presented. We refer to properties acquired or placed in-service prior to
the beginning of the earliest period presented and owned by us and in-service
through the end of the latest period presented as our Same Property Portfolio.
The Same Property Portfolio therefore excludes properties acquired, placed
in-service or in development or redevelopment after the beginning of the
earliest period presented or disposed of prior to the end of the latest period
presented.

Net operating income ("NOI") is a non-GAAP financial measure equal to net income
attributable to Boston Properties, Inc. common shareholders and net income
attributable to Boston Properties Limited Partnership common unitholders, as
applicable, the most directly comparable GAAP financial measures, plus (1)
preferred dividends/distributions, net income attributable to noncontrolling
interests, interest expense, loss from early extinguishment of debt, impairment
loss, depreciation and amortization expense, transaction costs, payroll and
related costs from management services contracts and corporate general and
administrative expense less (2) gains from investments in securities, interest
and other income (loss), gains on sales of real estate, income (loss) from
unconsolidated joint ventures, direct reimbursements of payroll and related
costs from management services contracts and development and management services
revenue. We use NOI internally as a performance measure and believe it provides
useful information to investors regarding our results of operations and
financial condition because, when compared across periods, it reflects the
impact on operations from trends in occupancy rates, rental rates, operating
costs and acquisition and development activity on an unleveraged basis,
providing perspective not immediately apparent from net income attributable to
Boston Properties, Inc. common shareholders and net income attributable to
Boston Properties Limited Partnership common unitholders. For example, interest
expense is not necessarily linked to the operating performance of a real estate
asset and is often incurred at the corporate level as opposed to the property
level. Similarly, interest expense may be incurred at the property level even
though the financing proceeds may be used at the corporate level (e.g., used for
other investment activity). In addition, depreciation and amortization expense,
because of historical cost accounting and useful life estimates, may distort
operating performance measures at the property level. NOI presented by us may
not be comparable to NOI reported by other REITs or real estate companies that
define NOI differently.
We believe that, in order to facilitate a clear understanding of our operating
results, NOI should be examined in conjunction with net income attributable to
Boston Properties, Inc. common shareholders and net income attributable to
Boston Properties Limited Partnership common unitholders as presented in our
Consolidated Financial Statements. NOI should not be considered as a substitute
for net income attributable to Boston Properties, Inc. common shareholders or
net income attributable to Boston Properties Limited Partnership common
unitholders (determined in accordance with GAAP) or any other GAAP financial
measures and should only be considered together with and as a supplement to our
financial information prepared in accordance with GAAP.
The gains on sales of real estate, depreciation expense and impairment losses
may differ between BXP and BPLP as a result of previously applied acquisition
accounting by BXP for the issuance of common stock in connection with
non-sponsor OP Unit redemptions by BPLP. This accounting resulted in a step-up
of the real estate assets at BXP that was allocated to certain properties. The
difference between the real estate assets of BXP as compared to BPLP for certain
properties having an allocation of the real estate step-up will result in a
corresponding difference in gains on sales of real estate, depreciation expense
and impairment losses, when those properties are sold. For additional
information see the Explanatory Note that follows the cover page of this Annual
Report on Form 10-K.
Comparison of the year ended December 31, 2020 to the year ended December 31,
2019
The table below shows selected operating information for the Same Property
Portfolio and the Total Property Portfolio. The Same Property Portfolio consists
of 139 properties totaling approximately 38.6 million net rentable square feet,
excluding unconsolidated joint ventures. The Same Property Portfolio includes
properties acquired or placed in-service on or prior to January 1, 2019 and
owned and in service through December 31, 2020. The Total Property Portfolio
includes the effects of the other properties either acquired, placed in-service,
in development or redevelopment after January 1, 2019 or disposed of on or prior
to December 31, 2020. This table includes a reconciliation from the Same
Property Portfolio to the Total Property Portfolio by also providing information
for the years ended December 31, 2020 and 2019 with respect to the properties
that were acquired, placed in-service, in development or redevelopment or sold.

(1)Rental Revenue is equal to Revenue less Development and Management Services
Revenue and Direct Reimbursements of Payroll and Related Costs from Management
Services Revenue per the Consolidated Statements of Operations, excluding the
residential and hotel revenue that is noted below. We use Rental Revenue
internally as a performance measure and in calculating other non-GAAP financial
measures (e.g., NOI), which provides investors with information regarding our
performance that is not immediately apparent from the comparable non-GAAP
measures and allows investors to compare operating performance between periods.
(2)For a detailed discussion of NOI, including the reasons management believes
NOI is useful to investors, see page 76. Residential Net Operating Income for
the year ended December 31, 2020 and 2019 is comprised of Residential Revenue of
$38,146 and $36,914 less Residential Expenses of $18,739 and $15,985,
respectively. Hotel Net Operating Income for the year ended December 31, 2020
and 2019 is comprised of Hotel Revenue of $7,478 and $48,589 less Hotel Expenses
of $13,136 and $34,004, respectively, per the Consolidated Statements of
Operations.

Same Property Portfolio
Lease Revenue (Excluding Termination Income)
Lease revenue from the Same Property Portfolio decreased by approximately $101.5
million for the year ended December 31, 2020 compared to 2019. Approximately
$87.3 million of the decrease was related to write-offs, which are discussed
below. In addition to the impact of the write-offs, we experienced an
approximately $14.2 million decrease due to our average occupancy decreasing
from 93.9% to 93.2%. Average revenue per square foot was approximately the same
for both years.
Under ASC 842, the write-off for bad debt, including accrued rent, is recorded
as a reduction to lease revenue. As a result, during the year ended December 31,
2020, for our Same Property Portfolio, we wrote off approximately $65.4 million
and $21.9 million of accrued rent and accounts receivable balances,
respectively. These write-offs related to tenants, primarily in the retail,
entertainment and co-working sectors, that either terminated their leases or for
which we determined that substantially all of their amount owed, related to
accrued rent and/or accounts receivable balances, were no longer probable of
collection.
In addition, as a result of COVID-19, for the Same Property Portfolio, during
2020, we executed lease modification agreements for approximately 3.5 million
square feet and granted approximately $63.9 million of cash rent abatements and
deferrals, of which approximately $50.0 million related to rental charges for
2020. Although some of the lease modifications were deferrals under which we
expect the tenant will pay us in full primarily in 2021, the majority of the
lease modifications involved extending the lease term (in some cases for a year
or more) or providing for a period of time where the tenant will only pay
percentage rent. As a result of the lease modification agreements that extended
the lease term, we expect to see an increase in the cash rent we will receive in
the future.
In April 2020, the Financial Accounting Standards Board ("FASB") staff issued a
question and answer document ("Lease Modification Q & A") related to the
application of lease accounting guidance for lease concessions, in accordance
with ASC 842, as a result of COVID-19. We did not utilize the guidance provided
in the Lease Modification Q & A and instead elected to continue to account for
the COVID-19 lease concessions on a lease-by-lease basis in accordance with the
existing lease modification accounting framework (See Note 4 to the Consolidated
Financial Statements). As such, our accrued rent balances, which are a component
of lease revenue, include the accounting impact (adjusted for write-offs) from
the rent abatements, deferrals and extensions that were executed during 2020.
We expect the volume of lease modifications as a result of COVID-19 to decrease
as vaccines are rolled out and the pandemic subsides. However, the degree to
which our tenants' businesses are negatively impacted by COVID-19 may leave some
tenants still unable to meet their rental payment obligations and result in a
reduction in our cash flows. We may write off additional accrued rent or
accounts receivable balances and this could have a material adverse effect on
lease revenue. See Item 1A: "Risk Factors" for additional details.
Termination Income
Termination income decreased by approximately $5.7 million for the year ended
December 31, 2020 compared to 2019.
Termination income for the year ended December 31, 2020 related to 38 tenants
across the Same Property Portfolio and totaled approximately $8.9 million, which
was primarily related to tenants that terminated leases early in the New York
region.
Termination income for the year ended December 31, 2019 related to 39 tenants
across the Same Property Portfolio and totaled approximately $14.6 million, of
which approximately $8.2 million is from two tenants that terminated leases
early at 399 Park Avenue in New York City.
Parking and Other Revenue
Parking and other revenue decreased by approximately $33.1 million for the year
ended December 31, 2020 compared to 2019. Parking revenue decreased by
approximately $34.7 million while other revenue increased by approximately $1.6
million. The decrease in parking revenue was primarily due to a decrease in
transient and monthly parking.

  Table of Contents
During the majority of 2020, with stay-at-home orders in effect, business
closures and people working remotely in a majority of regions in which our
properties are located, we generated minimal hourly/daily parking revenue. As a
result, for the year ended December 31, 2020, transient and monthly parking
decreased by approximately $24.1 million and $8.0 million, respectively,
compared to 2019. However, as these conditions shifted, and stay-at-home orders
were partially or fully lifted, businesses began to open, people began to return
to working in an office setting, and, as we expected, we have begun to see, an
increase in parking revenue. Some of our monthly parking revenues are
contractual agreements embedded in our leases, and some are at will individual
agreements.
Real Estate Operating Expenses
Real estate operating expenses from the Same Property Portfolio decreased by
approximately $24.2 million, or 2.4%, for the year ended December 31, 2020
compared to 2019, due primarily to decreases in utility and cleaning expense of
approximately $11.9 million, or 13.7%, and $20.8 million, or 19.1%,
respectively, partially offset by an increase in other real estate operating
expenses of $8.5 million, or 1.1%. The decreases in utility and cleaning expense
were experienced across the portfolio and were primarily driven by a decrease in
physical tenant occupancy, which led to lower demand for electricity, HVAC, and
cleaning.
Properties Acquired Portfolio
The table below lists the properties acquired between January 1, 2019 and
December 31, 2020. Rental revenue and real estate operating expenses increased

(1)Average Monthly Rental Rate is calculated as the average of the quotients
obtained by dividing (A) rental revenue as determined in accordance with GAAP,
by (B) the number of occupied units for each month within the applicable fiscal
period.
(2)Average Physical Occupancy is defined as (1) the average number of occupied
units divided by (2) the total number of units, expressed as a percentage.
(3)Average Economic Occupancy is defined as (1) total possible revenue less
vacancy loss divided by (2) total possible revenue, expressed as a percentage.
Total possible revenue is determined by valuing average occupied units at
contract rates and average vacant units at Market Rents. Vacancy loss is
determined by valuing vacant units at current Market Rents. By measuring vacant
units at their Market Rents, Average Economic Occupancy takes into account the
fact that units of different sizes and locations within a residential property
have different economic impacts on a residential property's total possible gross
revenue. Market Rents used by us in calculating Economic Occupancy are based on
the current market rates set by the managers of our residential properties based
on their experience in renting their residential property's units and publicly
available market data. Actual market rents and trends in such rents for a region
as reported by others may vary materially from Market Rents used by us. Market
Rents for a period are based on the average Market Rents during that period and
do not reflect any impact for cash concessions.
Hotel Net Operating Income
Net operating income for the Boston Marriott Cambridge hotel property decreased
by approximately $20.2 million for the year ended December 31, 2020 compared to
2019.
The Boston Marriott Cambridge closed in March 2020 due to COVID-19. The hotel
re-opened on October 2, 2020 and has been operating at a diminished occupancy
due to the continued impacts that COVID-19 has had on business and leisure
travel. The closing of the hotel for more than two fiscal quarters, weak demand
and low occupancy since its re-opening, have had, and are expected to continue
to have, a material adverse effect on the hotel's operations. We expect hotel
occupancy to remain low until a sufficient number of people have been vaccinated
and the demand for travel and leisure returns to historical levels. See Item 1A:
"Risk Factors" for additional details.
The following reflects our occupancy and rate information for the Boston
Marriott Cambridge hotel for the year ended December 31, 2020 and 2019.

Other Operating Revenue and Expense Items
Development and Management Services Revenue
Development and management services revenue decreased by approximately $10.4
million for the year ended December 31, 2020 compared to 2019. Development and
management services revenue decreased by approximately $10.0 million and $0.4
million, respectively. The decrease in development services revenue was
primarily related to a decrease of approximately $10.7 million in development
fees from the completion of development projects in the Boston and Washington,
DC regions and fees associated with tenant improvement projects earned in the
Boston region, partially offset by an increase of approximately $0.7 million in
fees associated with tenant improvement projects earned in the Washington, DC
region. The decrease in management services revenue was primarily related to a
decrease in leasing commissions earned from our unconsolidated joint ventures in
the Boston region, partially offset by property management fees earned from
third-party owned buildings in the Washington, DC region and our Gateway Commons
unconsolidated joint venture, which was deconsolidated on January 28, 2020.
General and Administrative Expense
General and administrative expense decreased by approximately $7.7 million for
the year ended December 31, 2020 compared to 2019 primarily due to a decrease in
compensation expense of approximately $7.4 million and an approximately $0.3
million decrease in other general and administrative expenses. The decrease in
compensation expense was related to (1) an approximately $2.5 million increase
in capitalized wages, which decreases general and administrative expenses, (2)
an approximately $1.1 million decrease in the value of our deferred compensation
plan, (3) an approximately $0.6 million decrease in health care costs and (3) an
approximately $3.2 million decrease in other compensation-related expenses. The
increase in capitalized wages is shown as an decrease to general and
administrative expense as some of these costs were capitalized and included in
real estate assets on our Consolidated Balance Sheets (see below).
Wages directly related to the development of rental properties are capitalized
and included in real estate assets on our Consolidated Balance Sheets and
amortized over the useful lives of the applicable asset or lease term.
Capitalized wages for the year ended December 31, 2020 and 2019 were
approximately $12.9 million and $10.4 million, respectively. These costs are not
included in the general and administrative expenses discussed above.
Transaction Costs
Transaction costs decreased by approximately $0.5 million for the year ended
December 31, 2020 compared to 2019 due primarily to costs incurred in connection
with the pursuit and formation of new joint ventures. In general, transaction
costs relating to the formation of new and pending joint ventures and the
pursuit of other transactions are expensed as incurred.
Depreciation and Amortization Expense
Depreciation expense may differ between BXP and BPLP as a result of previously
applied acquisition accounting by BXP for the issuance of common stock in
connection with non-sponsor OP Unit redemptions by BPLP.  This accounting
resulted in a step-up of the real estate assets at BXP that was allocated to
certain properties.  The difference between the real estate assets of BXP as
compared to BPLP for certain properties having an allocation of the real estate
step-up will result in a corresponding difference in depreciation expense. For
additional information see the Explanatory Note that follows the cover page of
this Annual Report on Form 10-K.

Direct Reimbursements of Payroll and Related Costs From Management Services
Contracts and Payroll and Related Costs From Management Service Contracts
We have determined that amounts reimbursed for payroll and related costs
received from third parties in connection with management services contracts
should be reflected on a gross basis instead of on a net basis as we have
determined that we are the principal under these arrangements. We anticipate
that these two financial statement line items will generally offset each other.

Income (loss) from Unconsolidated Joint Ventures
For the year ended December 31, 2020 compared to 2019, income (loss) from
unconsolidated joint ventures decreased by approximately $131.7 million
primarily due to, (1) a $60.5 million non-cash impairment charge at our Dock 72
joint venture during the year ended December 31, 2020, (2) a $47.5 million gain
on sale of real estate from the sale of 540 Madison Avenue during the year ended
December 31, 2019 and the resulting loss of income thereafter, (3) our share of
the write-off of accrued rent and accounts receivable of approximately $16.2
million and $1.5 million, respectively for the year ended December 31, 2020, (4)
an approximately $3.3 million net loss from our
                                       83
--------------------------------------------------------------------------------

Gateway Commons joint venture, primarily due to depreciation and amortization
expense and (5) the fully placing in-service of the Hub50House residential
property, which is not expected to be stabilized until the first quarter of
2022, decreased our net income by approximately $3.4 million. These decreases
were partially offset by an approximately $5.8 million gain on sale of real
estate from the sale of Annapolis Junction Building Eight and two undeveloped
land parcels during the year ended December 31, 2020.
Under ASC 842, the write-off for bad debt, including accrued rent, is recorded
as a reduction to lease revenue. As a result, during the year ended December 31,
2020, for our unconsolidated joint ventures, we wrote off our share of the
accrued rent and accounts receivable balances of approximately $16.2 million and
$1.5 million, respectively. These write-offs related to tenants that either
terminated their leases or for which we determined that their accrued rent
and/or accounts receivable balances were no longer probable of collection.
In addition, as a result of COVID-19, for properties owned by our unconsolidated
joint ventures, during 2020, the joint ventures executed lease modification
agreements for approximately 1.1 million square feet. As a result of these lease
modification agreements, our share of the total cash rent abatements and
deferrals granted was approximately $9.5 million, of which approximately $7.5
million was related to rental charges for 2020. Although some of the lease
modifications were deferrals where we expect the tenant will pay the joint
venture in full primarily in 2021, the majority of the lease modifications
involved extending the lease term (in some cases for longer than a year). As a
result of the lease modification agreements that extended the lease term, we
expect to see an increase in the cash rent we will receive in the future.
In April 2020, the FASB staff issued the Lease Modification Q & A related to the
application of lease accounting guidance for lease concessions, in accordance
with ASC 842, as a result of COVID-19. We did not utilize the guidance provided
in the Lease Modification Q & A and instead elected to continue to account for
the COVID-19 lease concessions on a lease-by-lease basis in accordance with the
existing lease modification accounting framework (See Note 4 to the Consolidated
Financial Statements). As such, the accrued rent balances, which are a component
of lease revenue, include the accounting impact (adjusted for write-offs) from
the rent abatements, deferrals and extensions that were executed during 2020.
The joint ventures expect the volume of lease modifications as a result of
COVID-19 to start to decrease. However, the degree to which tenants' businesses
are negatively impacted by COVID-19 could leave some tenants still unable to
meet their rental payment obligations and result in a reduction in cash flows.
Our unconsolidated joint ventures may write-off additional accrued rent or
accounts receivable balances and this could have a material adverse effect on
lease revenue. See Item 1A: "Risk Factors" for additional details.
Gains on Sales of Real Estate
Gains on sales of real estate may differ between BXP and BPLP as a result of
previously applied acquisition accounting by BXP for the issuance of common
stock in connection with non-sponsor OP Unit redemptions by BPLP. This
accounting resulted in a step-up of the real estate assets at BXP that was
allocated to certain properties. The difference between the real estate assets
of BXP as compared to BPLP for certain properties having an allocation of the
real estate step-up will result in a corresponding difference in the gains on
sales of real estate when those properties are sold. For additional information,
see the Explanatory Note that follows the cover page of this Annual Report on
Form 10-K.

Interest and Other Income (Loss)
Interest and other income (loss) decreased by approximately $13.0 million for
the year ended December 31, 2020 compared to 2019, due primarily to a decrease
of approximately $11.2 million in interest income which was primarily due to a
decrease in interest rates.
On January 1, 2020, we adopted ASU 2016-13, "Financial Instruments - Credit
Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" ("ASU
2016-13") and, as a result, we were required to record an allowance for current
expected credit losses related to our outstanding (1) related party note
receivable, (2) notes receivable and (3) off-balance sheet credit exposures (See
Note 2 to the Consolidated Financial Statements). For the year ended
December 31, 2020 the allowance for current expected credit losses was $1.8
million.
Gains from Investments in Securities
Gains from investments in securities for the year ended December 31, 2020 and
2019 related to investments that we have made to reduce our market risk relating
to deferred compensation plans that we maintain for BXP's officers and former
non-employee directors. Under the deferred compensation plans, each officer or
non-employee director who is eligible to participate is permitted to defer a
portion of the officer's current income or the non-employee director's
compensation on a pre-tax basis and receive a tax-deferred return on these
deferrals based on the performance of specific investments selected by the
officer or non-employee director. In order to reduce our
                                       86
--------------------------------------------------------------------------------
  Table of Contents
market risk relating to these plans, we typically acquire, in a separate account
that is not restricted as to its use, similar or identical investments as those
selected by each officer or non-employee director. This enables us to generally
match our liabilities to BXP's officers or former non-employee directors under
our deferred compensation plans with equivalent assets and thereby limit our
market risk. The performance of these investments is recorded as gains from
investments in securities. During the year ended December 31, 2020 and 2019, we
recognized gains of approximately $5.3 million and $6.4 million, respectively,
on these investments. By comparison, our general and administrative expense
increased by approximately $5.3 million and $6.4 million during the year ended
December 31, 2020 and 2019, respectively, as a result of increases in our
liability under our deferred compensation plans that was associated with the
performance of the specific investments selected by officers and former
non-employee directors of BXP participating in the plans.
Impairment Loss
Impairment loss may differ between BXP and BPLP as a result of previously
applied acquisition accounting by BXP for the issuance of common stock in
connection with non-sponsor OP Unit redemptions by BPLP.  This accounting
resulted in a step-up of the real estate assets at BXP that was allocated to
certain properties.  The difference between the real estate assets of BXP as
compared to BPLP for certain properties having an allocation of the real estate
step-up will result in a corresponding difference in depreciation expense. For
additional information see the Explanatory Note that follows the cover page of
this Annual Report on Form 10-K.
At March 31, 2019, we evaluated the expected hold period of our One Tower Center
property located in East Brunswick, New Jersey and, based on a
shorter-than-expected hold period, we reduced the carrying value of the property
to its estimated fair value at March 31, 2019 and recognized an impairment loss
totaling approximately $24.0 million for BXP and approximately $22.3 million for
BPLP. Our estimated fair value was based on a pending offer from a third party
to acquire the property and the subsequent execution of a purchase and sale
agreement on April 18, 2019 for a gross sale price of approximately $38.0
million. On June 3, 2019, we completed the sale of the property. One Tower
Center is an approximately 410,000 net rentable square foot Class A office
property. We did not have any impairments during the year ended December 31,
2020.
Loss From Early Extinguishment of Debt
On September 18, 2019, BPLP completed the redemption of $700.0 million in
aggregate principal amount of its 5.625% senior notes due November 15, 2020. The
redemption price was approximately $740.7 million. The redemption price included
approximately $13.5 million of accrued and unpaid interest to, but not
including, the redemption date. Excluding the accrued and unpaid interest, the
redemption price was approximately 103.90% of the principal amount being
redeemed. We recognized a loss from early extinguishment of debt totaling
approximately $28.0 million, which amount included the payment of the redemption
premium totaling approximately $27.3 million.
On December 19, 2019, we used available cash to repay the bond financing
collateralized by our New Dominion Technology Park, Building One property
totaling approximately $26.5 million. The bond financing bore interest at a
weighted-average fixed rate of approximately 7.69% per annum and was scheduled
to mature on January 15, 2021. We recognized a loss from early extinguishment of
debt totaling approximately $1.5 million, which amount included the payment of a
prepayment penalty totaling approximately $1.4 million. New Dominion Technology
Park, Building One is an approximately 235,000 net rentable square foot Class A
office property located in Herndon, Virginia.

Interest expense directly related to the development of rental properties is
capitalized and included in real estate assets on our Consolidated Balance
Sheets and amortized over the useful lives of the real estate or lease term. As
portions of properties are placed in-service, we cease capitalizing interest on
that portion and interest is then expensed. Interest capitalized for the years
ended December 31, 2020 and 2019 was approximately $53.9 million and $54.9
million, respectively. These costs are not included in the interest expense
referenced above.
On May 5, 2020, BPLP completed a public offering of $1.25 billion in aggregate
principal amount of its 3.250% unsecured senior notes due 2031 (See Note 8 to
the Consolidated Financial Statements). We used a portion of the net proceeds
from this offering for the repayment of borrowings outstanding under the
Revolving Facility.
On February 14, 2021, BPLP completed the redemption of $850.0 million in
aggregate principal amount of its 4.125% senior notes due May 15, 2021. The
redemption price was approximately $858.7 million, which was equal to par plus
approximately $8.7 million of accrued and unpaid interest to, but not including,
the redemption date.
At December 31, 2020, our variable rate debt consisted of BPLP's $2.0 billion
unsecured revolving credit facility (the "2017 Credit Facility"), which includes
the $500.0 million delayed draw term loan facility (the "Delayed Draw Facility")
and the $1.5 billion revolving line of credit (the "Revolving Facility"). The
Delayed Draw Facility had $500.0 million outstanding as of December 31, 2020.
The Revolving Facility did not have an outstanding balance as of December 31,
2020. For a summary of our consolidated debt as of December 31, 2020 and
December 31, 2019 refer to the heading "Liquidity and Capital
Resources-Capitalization-Debt Financing" within "Item 7-Management's Discussion
and Analysis of Financial Condition and Results of Operations."

_______________
(1)On April 1, 2019, we acquired our partner's 5% interest and subsequently own
100%.
(2)The increase during the year ended December 31, 2020 was related to
above-/below-market lease assets that were fully amortized in 2020.
(3)During the year ended December 31, 2020, we wrote off approximately $26.8
million of accrued rent and accounts receivable balances for tenants that either
terminated their leases or for which we determined their accrued rent and/or
accounts receivable balances, primarily retail tenants, were no longer probable
of collection. Approximately $14.7 million represents our share of the
write-offs. As a result of these terminations, lease revenue decreased for the
year ended December 31, 2020.
(4)During the year ended December 31, 2020, we wrote off approximately $2.9
million of accrued rent and accounts receivable balances for tenants that either
terminated their leases or for which we determined their accrued rent and/or
accounts receivable balances, primarily tenants in the retail sector, were no
longer probable of collection. Approximately $1.6 million represents our share
of the write-offs. As a result of these terminations, lease revenue decreased
for the year ended December 31, 2020.
(5)The increase was primarily due to an increase in lease revenue from our
tenants.
(6)During the year ended December 31, 2020, we wrote off approximately $0.5
million of accrued rent and accounts receivable balances for tenants whose
balances we determined were no longer probable of collection. Approximately $0.3
million represents our share of the write-offs.
Noncontrolling Interest-Common Units of the Operating Partnership
For BXP, noncontrolling interest-common units of the Operating Partnership
increased by approximately $38.4 million for the year ended December 31, 2020
compared to 2019 due primarily to an increase in allocable income, which was the
result of recognizing a greater gain on sales of real estate amount during 2020
partially offset by a decrease in the noncontrolling interest's ownership
percentage. Due to our ownership structure, there is no corresponding line item
on BPLP's financial statements.
Liquidity and Capital Resources
General
Our principal liquidity needs for the next twelve months and beyond are to:
•fund normal recurring expenses;
•meet debt service and principal repayment obligations, including balloon
payments on maturing debt;
•fund development/redevelopment costs;
•fund capital expenditures, including major renovations, tenant improvements and
leasing costs;
•fund planned and possible acquisitions of properties, either directly or
indirectly through the acquisition of equity interests therein;
•fund dividend requirements on BXP's Series B Preferred Stock; and
•make the minimum distribution required to enable BXP to maintain its REIT
qualification under the Internal Revenue Code of 1986, as amended.
                                       89
--------------------------------------------------------------------------------
  Table of Contents
We expect to satisfy these needs using one or more of the following:
•cash flow from operations;
•distribution of cash flows from joint ventures;
•cash and cash equivalent balances;
•BPLP's 2017 Credit Facility;
•short-term bridge facilities;
•construction loans;
•long-term secured and unsecured indebtedness (including unsecured exchangeable
indebtedness);
•sales of real estate; and
•issuances of BXP equity securities and/or additional preferred or common units
of partnership interest in BPLP.
We draw on multiple financing sources to fund our long-term capital needs. Our
current development properties are expected to be primarily funded with our
available cash balances, construction loans and BPLP's Revolving Facility. We
use BPLP's Revolving Facility primarily as a bridge facility to fund acquisition
opportunities, refinance outstanding indebtedness and meet short-term
development and working capital needs. Although we may seek to fund our
development projects with construction loans, which may require guarantees by
BPLP, the financing for each particular project ultimately depends on several
factors, including, among others, the project's size and duration, the extent of
pre-leasing and our available cash and access to cost effective capital at the
given time.

Lease revenue (which includes recoveries from tenants), other income from
operations, available cash balances, mortgage financings, unsecured indebtedness
and draws on BPLP's Revolving Facility are the principal sources of capital that
we use to fund operating expenses, debt service, maintenance and repositioning
capital expenditures, tenant improvements and the minimum distribution required
to enable BXP to maintain its REIT qualification. We seek to maximize income
from our existing properties by maintaining quality standards for our properties
that promote high occupancy rates and permit increases in rental rates while
reducing tenant turnover and controlling operating expenses. Our sources of
revenue also include third-party fees generated by our property management,
leasing and development and construction businesses, as well as the sale of
assets from time to time. We believe these sources of capital will continue to
provide the funds necessary for our short-term liquidity needs, including our
properties under development and redevelopment.
Material adverse changes in one or more sources of capital, including from the
impacts of COVID-19, may adversely affect our net cash flows. During the fourth
quarter of 2020, our rent collections remained strong as we collected 99.7% of
rents from our office tenants and 99.1% of rents from all tenants, including
retail tenants. However, COVID-19 resulted in the write-off of accrued rent
balances for all remaining co-working tenants. Decreases in parking and other
revenue and the continued disruption in operations for our hotel reduced our
revenue for the fourth quarter of 2020.
Cash rent abatements and deferrals primarily related to COVID-19 were
approximately $19.2 million in the fourth quarter. This amount represents our
consolidated cash rent abatements and deferrals plus our share of the cash rent
abatements and deferrals from the unconsolidated joint ventures (calculated
based on our ownership percentage) minus our partners' share of cash rent
abatements and deferrals from our consolidated joint ventures (calculated based
upon the partners' percentage ownership interests).
To date, these impacts have not adversely affected our ability to fund operating
expenses, dividends and distributions, debt service payments, maintenance and
repositioning capital expenditures and tenant improvements. Any future material
adverse change in the cash provided by our operations may affect our ability to
comply with the financial covenants under BPLP's 2017 Credit Facility or its
unsecured senior notes.
Our primary uses of capital over the next twelve months will be the completion
of our current and committed development and redevelopment projects. Following
the redemption of the $850 million aggregate principal amount of BPLP's 4.125%
senior unsecured notes on February 14, 2021, we have no further 2021 debt
maturities, other than three loans borrowed by our unconsolidated joint ventures
of which our share is approximately $102 million. As of December 31, 2020, our
share of the remaining development and redevelopment costs that we expect to
fund through 2024 was approximately $849 million. In addition, we anticipate
development/redevelopment starts in 2021 of over $700 million, the majority of
which are new life sciences developments and conversions.
To satisfy these capital needs, as of February 22, 2021, we had approximately
$517 million of cash and cash equivalents, of which approximately $155 million
is attributable to our consolidated joint venture partners.
Although the full impact of COVID-19 on our liquidity and capital resources, as
well as the duration of such impact, will depend on a wide range of factors, all
of which are highly uncertain and cannot be predicted with confidence at this
time, we believe that our strong liquidity, including the approximately $1.5
billion available under the Revolving Facility and available cash, as of
February 22, 2021, is sufficient to fund our remaining capital requirements on
existing development and redevelopment projects, repay our maturing indebtedness
when due, satisfy our REIT distribution requirements and still allow us to act
opportunistically on attractive investment opportunities.
We have not sold any shares under BXP's $600.0 million "at the market" equity
offering program.
During 2020 we continued to access various sources of capital, including the
sale of more than $920 million of assets generating approximately $538 million
of proceeds, the issuance by BPLP in May 2020 of $1.25 billion in aggregate
principal amount of its 3.25% senior unsecured notes due 2031 and the completion
of $731.6 million of secured debt transactions to refinance maturing debt, of
which our share of the aggregate principal is $268.3 million. The refinancing
transactions included the following:
•A $250.0 million mortgage loan collateralized by Dock 72, a 669,000 square-foot
Class A office property in Brooklyn, New York in which we have a 50% interest.
The new loan matures on December 18, 2023.
                                       92
--------------------------------------------------------------------------------
  Table of Contents
•A $125.0 million mortgage loan collateralized by Market Square North, a 418,000
square foot Class A office property in Washington, DC in which we have a 50%
interest. The new loan matures on November 10, 2025.
•A $325.0 million mortgage loan collateralized by Metropolitan Square, a 654,000
square foot Class A office property in Washington, DC, in which we have a 20%
interest. The new loan matures on July 7, 2022.
We may seek to enhance our liquidity to fund our foreseeable potential
development activity, pursue additional attractive investment opportunities and
refinance or repay indebtedness. Depending on interest rates and overall
conditions in the debt and equity markets, we may decide to access either or
both of these markets in advance of the need for the funds. Doing so may result
in us carrying additional cash and cash equivalents pending our use of the
proceeds, which would increase our net interest expense and be dilutive to our
earnings.
REIT Tax Distribution Considerations
Dividend
BXP as a REIT is subject to a number of organizational and operational
requirements, including a requirement that BXP currently distribute at least 90%
of its annual taxable income (excluding capital gains and with certain other
adjustments). Our policy is for BXP to distribute at least 100% of its taxable
income, including capital gains, to avoid paying federal tax. On December 17,
2019, the Board of Directors of BXP increased our regular quarterly dividend
from $0.95 per common share to $0.98 per common share, or 3%, beginning with the
fourth quarter of 2019. Common and LTIP unitholders of limited partnership
interest in BPLP, received the same total distribution per unit.
BXP's Board of Directors will continue to evaluate BXP's dividend rate in light
of our actual and projected taxable income (including gains on sales), liquidity
requirements and other circumstances, including the impact of COVID-19, and
there can be no assurance that the future dividends declared by BXP's Board of
Directors will not differ materially from the current quarterly dividend amount.
Sales
To the extent that we sell assets at a gain and cannot efficiently use the
proceeds in a tax deferred manner for either our development activities or
attractive acquisitions, BXP would, at the appropriate time, decide whether it
is better to declare a special dividend, adopt a stock repurchase program,
reduce indebtedness or retain the cash for future investment opportunities. Such
a decision will depend on many factors including, among others, the timing,
availability and terms of development and acquisition opportunities, our
then-current and anticipated leverage, the cost and availability of capital from
other sources, the price of BXP's common stock and REIT distribution
requirements. At a minimum, we expect that BXP would distribute at least that
amount of proceeds necessary for BXP to avoid paying corporate level tax on the
applicable gains realized from any asset sales.
From time to time in selected cases, whether due to a change in use, structuring
issues to comply with applicable REIT regulations or other reasons, we may sell
an asset that is held by a taxable REIT subsidiary ("TRS"). Such a sale by a TRS
would be subject to federal and local taxes.
Cash Flow Summary
The following summary discussion of our cash flows is based on the Consolidated
Statements of Cash Flows and is not meant to be an all-inclusive discussion of
the changes in our cash flows for the periods presented below.
Cash and cash equivalents and cash held in escrows aggregated approximately $1.7
billion and $0.7 billion at December 31, 2020 and 2019, respectively,
representing an increase of approximately $1.0 billion. The following table sets
forth changes in cash flows:

Our principal source of cash flow is related to the operation of our properties.
The weighted-average term of our in-place leases, excluding residential units,
was approximately 7.4 years, as of December 31, 2020, including leases signed by
our unconsolidated joint ventures, with occupancy rates historically in the
range of 90% to 94%. Generally, our properties generate a relatively consistent
stream of cash flow that provides us with resources to pay operating expenses,
debt service and fund regular quarterly dividend and distribution payment
requirements. In addition, over the past several years, we have raised capital
through the sale of some of our properties and through secured and unsecured
borrowings.
The full extent of the impact of COVID-19 on our business, operations and
financial results will depend on numerous evolving factors that we may not be
able to accurately predict. In addition, we cannot predict the impact that
COVID-19 will have on our tenants, employees, contractors, lenders, suppliers,
vendors and joint venture partners; any material adverse effect on these parties
could also have a material adverse effect on us. See Item 1A: "Risk Factors" for
additional details.
Cash is used in investing activities to fund acquisitions, development, net
investments in unconsolidated joint ventures and maintenance and repositioning
capital expenditures. We selectively invest in new projects that enable us to
take advantage of our development, leasing, financing and property management
skills and invest in existing buildings to enhance or maintain their market
position. Cash used in investing activities for the year ended December 31, 2020
consisted primarily of acquisitions of real estate, development projects,
building and tenant improvements and capital contributions to unconsolidated
joint ventures, partially offset by the proceeds from the sales of real estate
and capital distributions from unconsolidated joint ventures. Cash used in
investing activities for the year ended December 31, 2019 consisted primarily of
the acquisition of real estate, development projects, building and tenant
improvements and capital contributions to unconsolidated joint ventures,
partially offset by the proceeds from the sale of real estate and capital
distributions from unconsolidated joint ventures, as detailed below:

Consolidated Debt to Consolidated Market Capitalization Ratio is a measure of
leverage commonly used by analysts in the REIT sector. We present this measure
as a percentage and it is calculated by dividing (A) our consolidated debt by
(B) our consolidated market capitalization, which is the market value of our
outstanding equity securities plus our consolidated debt. Consolidated market
capitalization is the sum of:
(1)   our consolidated debt; plus
(2)   the product of (x) the closing price per share of BXP common stock on
December 31, 2020, as reported by the New York Stock Exchange, multiplied by (y)
the sum of:
(i)   the number of outstanding shares of common stock of BXP,
(ii)   the number of outstanding OP Units in BPLP (excluding OP Units held by
BXP),
(iii)   the number of OP Units issuable upon conversion of all outstanding LTIP
Units, assuming all conditions have been met for the conversion of the LTIP
Units, and
(iv)   the number of OP Units issuable upon conversion of 2012 OPP Units, 2013 -
2017 MYLTIP Units that were issued in the form of LTIP Units; plus
(3)   the aggregate liquidation preference ($2,500 per share) of the outstanding
shares of BXP's 5.25% Series B Cumulative Redeemable Preferred Stock.
The calculation of consolidated market capitalization does not include LTIP
Units issued in the form of MYLTIP Awards unless and until certain performance
thresholds are achieved and they are earned. Because their three-year
performance periods have not yet ended, 2018 - 2020 MYLTIP Units are not
included in this calculation as of December 31, 2020.

  Table of Contents
We also present BXP's Share of Market Capitalization and BXP's Share of
Debt/BXP's Share of Market Capitalization, which are calculated in the same
manner, except that BXP's Share of Debt is utilized instead of our consolidated
debt in both the numerator and the denominator. BXP's Share of Debt is defined
as our consolidated debt plus our share of debt from our unconsolidated joint
ventures (calculated based upon our ownership percentage), minus our partners'
share of debt from our consolidated joint ventures (calculated based upon the
partners' percentage ownership interests adjusted for basis differentials).
Management believes that BXP's Share of Debt provides useful information to
investors regarding our financial condition because it includes our share of
debt from unconsolidated joint ventures and excludes our partners' share of debt
from consolidated joint ventures, in each case presented on the same basis. We
have several significant joint ventures and presenting various measures of
financial condition in this manner can help investors better understand our
financial condition and/or results of operations after taking into account our
economic interest in these joint ventures.  We caution investors that the
ownership percentages used in calculating BXP's Share of Debt may not completely
and accurately depict all of the legal and economic implications of holding an
interest in a consolidated or unconsolidated joint venture. For example, in
addition to partners' interests in profits and capital, venture agreements vary
in the allocation of rights regarding decision making (both for routine and
major decisions), distributions, transferability of interests, financing and
guarantees, liquidations and other matters.  Moreover, in some cases we exercise
significant influence over, but do not control, the joint venture in which case
GAAP requires that we account for the joint venture entity using the equity
method of accounting and we do not consolidate it for financial reporting
purposes. In other cases, GAAP requires that we consolidate the venture even
though our partner(s) own(s) a significant percentage interest.  As a result,
management believes that the presentation of BXP's Share of a financial measure
should not be considered a substitute for, and should only be considered with
and as a supplement to our financial information presented in accordance with
GAAP.
We present these supplemental ratios because our degree of leverage could affect
our ability to obtain additional financing for working capital, capital
expenditures, acquisitions, development or other general corporate purposes and
because different investors and lenders consider one or both of these ratios.
Investors should understand that these ratios are, in part, a function of the
market price of the common stock of BXP and as such will fluctuate with changes
in such price, and they do not necessarily reflect our capacity to incur
additional debt to finance our activities or our ability to manage our existing
debt obligations. However, for a company like BXP, whose assets are primarily
income-producing real estate, these ratios may provide investors with an
alternate indication of leverage, so long as they are evaluated along with the
ratio of indebtedness to other measures of asset value used by financial
analysts and other financial ratios, as well as the various components of our
outstanding indebtedness.

"Liquidity and Capital Resources-Capitalization-Off-Balance Sheet

and Analysis of Financial Condition and Results of Operations" and for a

Debt Financing
As of December 31, 2020, we had approximately $13.0 billion of outstanding
consolidated indebtedness, representing approximately 44.07% of our Consolidated
Market Capitalization as calculated above consisting of approximately (1) $9.6
billion (net of discount and deferred financing fees) in publicly traded
unsecured senior notes having a GAAP weighted-average interest rate of 3.71% per
annum and maturities in 2021 through 2031 (See Notes 8 and 18 to the
Consolidated Financial Statements), (2) $2.9 billion (net of deferred financing
fees) of property-specific mortgage debt having a GAAP weighted-average interest
rate of 3.89% per annum and a weighted-average term of 5.3 years and (3) $499.4
million (net of deferred financing fees) outstanding under BPLP's 2017 Credit
Facility that matures on April 24, 2022.

Unsecured Credit Facility
On April 24, 2017, BPLP entered into the 2017 Credit Facility. Among other
things, the 2017 Credit Facility (1) increased the total commitment of the
Revolving Facility from $1.0 billion to $1.5 billion, (2) extended the maturity
date from July 26, 2018 to April 24, 2022, (3) reduced the per annum variable
interest rates, and (4) added a $500.0 million Delayed Draw Facility that
permitted BPLP to draw until the first anniversary of the closing date. Based on
BPLP's current credit rating, (1) the applicable Eurocurrency margins for the
Revolving Facility and Delayed Draw Facility are 87.5 basis points and 95 basis
points, respectively, and (2) the facility fee on the Revolving Facility
commitment is 0.15% per annum.
                                       99
--------------------------------------------------------------------------------
  Table of Contents
On April 24, 2018, BPLP exercised its option to draw $500.0 million on its
Delayed Draw Facility. The Delayed Draw Facility bears interest at a variable
rate equal to LIBOR plus 0.90% per annum based on BPLP's December 31, 2020
credit rating and matures on April 24, 2022.
As of December 31, 2020, BPLP had $500.0 million of borrowings outstanding under
its Delayed Draw Facility, no borrowings under its Revolving Facility and
letters of credit totaling approximately $2.5 million outstanding with the
ability to borrow approximately $1.5 billion under the Revolving Facility. As of
February 22, 2021, BPLP had $500.0 million of borrowings outstanding under its
Delayed Draw Facility, no borrowings under its Revolving Facility and letters of
credit totaling approximately $2.3 million outstanding with the ability to
borrow approximately $1.5 billion under the Revolving Facility.
Unsecured Senior Notes, Net
For a description of BPLP's outstanding unsecured senior notes as of
December 31, 2020, see Notes 8 and 18 to the Consolidated Financial Statements.
On May 5, 2020, BPLP completed a public offering of $1.25 billion in aggregate
principal amount of its 3.250% unsecured senior notes due 2031. The notes were
priced at 99.850% of the principal amount to yield an effective rate (including
financing fees) of approximately 3.343% per annum to maturity. The notes will
mature on January 30, 2031, unless earlier redeemed. The aggregate net proceeds
from the offering were approximately $1.24 billion after deducting underwriting
discounts and transaction expenses.
The indenture relating to the unsecured senior notes contains certain financial
restrictions and requirements, including (1) a leverage ratio not to exceed 60%,
(2) a secured debt leverage ratio not to exceed 50%, (3) an interest coverage
ratio of greater than 1.50, and (4) an unencumbered asset value of not less than
150% of unsecured debt. At December 31, 2020, BPLP was in compliance with each
of these financial restrictions and requirements.

(1)GAAP interest rate differs from the stated interest rate due to the inclusion
of the amortization of financing charges and the effects of hedging transactions
(if any).
(2)The mortgage loan requires interest only payments with a balloon payment due
at maturity.
(3)This property is owned by a consolidated entity in which we have a 60%
interest. The partners' share of the carrying amount has been adjusted for basis
differentials.
(4)In connection with the refinancing of the loan, we guaranteed the
consolidated entity's obligation to fund various reserves for tenant improvement
costs and allowances, leasing commissions and free rent obligations in lieu of
cash deposits. As of December 31, 2020, the maximum funding obligation under the
guarantee was approximately $30.6 million. We earn a fee from the joint venture
for providing the guarantee and have an agreement with our partners to reimburse
the joint venture for their share of any payments made under the guarantee (See
Note 10 to the Consolidated Financial Statements).
(5)This property is owned by a consolidated entity in which we have a 55%

financial instruments are dependent upon prevalent market interest rates. Our
primary market risk results from our indebtedness, which bears interest at fixed
and variable rates. The fair value of our debt obligations are affected by
changes in the market interest rates. We manage our market risk by matching
long-term leases with long-term, fixed-rate, non-recourse debt of similar
duration. We continue to follow a conservative strategy of generally pre-leasing
development projects on a long-term basis to creditworthy tenants in order to
achieve the most favorable construction and permanent financing terms.
Approximately 96.2% of our outstanding debt, excluding our unconsolidated joint
ventures, has fixed interest rates, which minimizes the interest rate risk
through the maturity of such outstanding debt. We also manage our market risk by
entering into hedging arrangements with financial institutions. Our primary
objectives when undertaking hedging transactions and derivative positions is to
reduce our floating rate exposure and to fix a portion of the interest rate for
anticipated financing and refinancing transactions. This in turn, reduces the
risks that the variability of cash flows imposes on variable rate debt. Our
strategy mitigates against future increases in our interest rates.
At December 31, 2020, our weighted-average coupon/stated rate on our fixed rate
outstanding Consolidated Debt was 3.65% per annum. At December 31, 2020, we had
$500.0 million outstanding of consolidated variable rate debt. At December 31,
2020, the GAAP interest rate on our variable rate debt was approximately 1.19%
per annum. If market interest rates on our variable rate debt had been 100 basis
points greater, total interest expense would have increased approximately $5.0
million, on an annualized basis, for the year ended December 31, 2020.
Funds from Operations
Pursuant to the revised definition of Funds from Operations adopted by the Board
of Governors of the National Association of Real Estate Investment Trusts
("Nareit"), we calculate Funds from Operations, or "FFO," for each of BXP and
BPLP by adjusting net income (loss) attributable to Boston Properties, Inc.
common shareholders and net income (loss) attributable to Boston Properties
Limited Partnership common unitholders (computed in accordance with GAAP),
respectively, for gains (or losses) from sales of properties, impairment losses
on depreciable real estate consolidated on our balance sheet, impairment losses
on our investments in unconsolidated joint ventures driven by a measurable
decrease in the fair value of depreciable real estate held by the unconsolidated
joint ventures and our share of real estate-related depreciation and
amortization. FFO is a non-GAAP financial measure. We believe the presentation
of FFO, combined with the presentation of required GAAP financial measures,
improves the understanding of operating results of REITs among the investing
public and helps make comparisons of REIT operating results more meaningful.
Management generally considers FFO to be useful measures for understanding and
comparing our operating results because, by excluding gains and losses related
to sales of previously depreciated operating real estate assets, impairment
losses and real estate asset depreciation and amortization (which can differ
across owners of similar assets in similar condition based on historical cost
accounting and useful life estimates), FFO can help investors compare the
operating performance of a company's real estate across reporting periods and to
the operating performance of other companies.
Our computation of FFO may not be comparable to FFO reported by other REITs or
real estate companies that do not define the term in accordance with the current
Nareit definition or that interpret the current Nareit definition differently.
We believe that in order to facilitate a clear understanding of our operating
results, FFO should be examined in conjunction with net income attributable to
Boston Properties, Inc. common shareholders and net
                                      101

  Table of Contents
income attributable to Boston Properties Limited Partnership as presented in our
Consolidated Financial Statements. FFO should not be considered as a substitute
for net income attributable to Boston Properties, Inc. common shareholders or
net income attributable to Boston Properties Limited Partnership common
unitholders (determined in accordance with GAAP) or any other GAAP financial
measures and should only be considered together with and as a supplement to our
financial information prepared in accordance with GAAP.
The impact that COVID-19 has had on our business, financial position and results
of operations during 2020 is discussed throughout this report. The full extent
of the impact of COVID-19 on our business, operations and financial results will
depend on numerous evolving factors that we may not be able to accurately
predict. The impact of COVID-19 on our revenue, in particular lease, parking and
hotel revenue was negatively impacted by COVID-19 for the year ended
December 31, 2020, thus negatively impacting our FFO. These decreases are
discussed under the heading "Comparison of the year ended December 31, 2020 to
the year ended December 31, 2019" within "Item 7-Management's Discussion and
Analysis of Financial Condition and Results of Operations."

(1)Amounts include principal and interest payments.
(2)Interest payments are calculated using the December 31, 2020 interest rate of
1.10%.
(3)Committed tenant-related obligations based on executed leases as of
December 31, 2020 (tenant improvements and lease commissions).
(4)Finance lease payments in 2024 include approximately $38.7 million related to
a purchase option that we are reasonably certain we will exercise.
We have various service contracts with vendors related to our property
management. In addition, we have certain other contracts we enter into in the
ordinary course of business that may extend beyond one year. These contracts
include terms that provide for cancellation with insignificant or no
cancellation penalties. Contract terms are generally between three and five
years.
During 2020, we paid approximately $314.2 million to fund tenant-related
obligations, including tenant improvements and leasing commissions.
In addition, we and our unconsolidated joint venture partners incurred
approximately $248 million of new tenant-related obligations associated with
approximately 3.7 million square feet of second generation leases, which
included approximately 340,000 square feet of lease modifications related to
COVID-19, or approximately $66 per square foot. In addition, we signed leases
for approximately 276,000 square feet at our development properties.  The
tenant-related obligations for the development properties are included within
the projects' "Estimated Total Investment" referred to in "Item 7-Management's
Discussion and Analysis of Financial Condition and Results of
Operations-Liquidity and Capital Resources." In the aggregate, during 2020, we
signed leases for approximately 4.0 million square feet of space, including
approximately 340,000 square feet of lease modifications related to COVID-19,
and incurred aggregate tenant-related obligations of approximately $293 million,
or approximately $72 per square foot.
Off-Balance Sheet Arrangements-Joint Venture Indebtedness
We have investments in unconsolidated joint ventures with our effective
ownership interests ranging from 20% to 60%. Fourteen of these ventures have
mortgage indebtedness. We exercise significant influence over, but do not
control, these entities. As a result, we account for them using the equity
method of accounting. See also Note 6 to the Consolidated Financial Statements.
At December 31, 2020, the aggregate carrying amount of debt, including both our
and our partners' share, incurred by these ventures was approximately $2.6
billion (of which our proportionate share is approximately $1.2 billion). The
table below summarizes the outstanding debt of these joint venture properties at
December 31, 2020. In addition to other guarantees specifically noted in the
table, we have

New Accounting Pronouncements
For a discussion of the new accounting pronouncements that may have an effect on
our Consolidated Financial Statements (See Note 2 to the Consolidated Financial
Statements).
Inflation
Most of our leases provide for separate real estate tax and operating expense
escalations over a base amount. In addition, many of our leases provide for
fixed base rent increases or indexed increases. We believe that inflationary
increases in costs may be at least partially offset by the contractual rent
increases and operating expense escalations.

Item 7A-Quantitative and Qualitative Disclosures about Market Risk.
The following table presents the aggregate carrying value of our mortgage notes
payable, net, unsecured senior notes, net, unsecured line of credit, unsecured
term loan, net and our corresponding estimate of fair value as of December 31,
2020. As of December 31, 2020, approximately $12.5 billion of these borrowings
bore interest at fixed rates and therefore the fair value of these instruments
is affected by changes in the market interest rates. As of December 31, 2020,
the weighted-average interest rate on our variable rate debt was LIBOR plus
0.95% (1.10%) per annum. The following table presents our aggregate fixed rate
debt obligations with corresponding weighted-average interest rates sorted by
maturity date and our aggregate variable rate debt obligations sorted by
maturity date.
The table below does not include our unconsolidated joint venture debt. For a

On February 14, 2021, BPLP completed the redemption of $850.0 million in
aggregate principal amount of its 4.125% senior notes due May 15, 2021. The
redemption price was approximately $858.7 million, which was equal to par plus
approximately $8.7 million of accrued and unpaid interest to, but not including,
the redemption date.
At December 31, 2020, the weighted-average coupon/stated rates on the fixed rate
debt stated above was 3.65% per annum. At December 31, 2020, our outstanding
variable rate debt based on LIBOR totaled approximately $500.0 million. At
December 31, 2020, the coupon/stated rate on our variable rate debt was
approximately 1.10% per annum. If market interest rates on our variable rate
debt had been 100 basis points greater, total interest expense would have
increased approximately $5.0 million for the year ended December 31, 2020.

The fair value amounts were determined solely by considering the impact of
hypothetical interest rates on our financial instruments. Due to the uncertainty
of specific actions we may undertake to minimize possible effects of market
interest rate increases, this analysis assumes no changes in our financial
structure.
Due to the uncertainty of specific actions we may undertake to minimize possible
effects of market interest rate increases, this analysis assumes no changes in
our financial structure. In the event that LIBOR is discontinued, the interest
rate for our variable rate debt and our unconsolidated joint ventures' variable
rate debt and the swap rate for our unconsolidated joint ventures' interest rate
swaps following such event will be based on an alternative variable rate as
specified in the applicable documentation governing such debt or swaps or as
otherwise agreed upon. Such an event would not affect our ability to borrow or
maintain already outstanding borrowings or our unconsolidated joint ventures'
ability to maintain its outstanding swaps, but the alternative variable rate
could be higher and more volatile than LIBOR prior to its discontinuance. We
understand that LIBOR is expected to remain available through the end of 2021,
but may be discontinued or otherwise become unavailable thereafter.

Additional disclosure about market risk is incorporated herein by reference from
"Item 7-Management's Discussion and Analysis of Financial Condition and Results
of Operations-Liquidity and Capital Resources-Market Risk."
