The following discussion should be read in conjunction with the financial
statements and notes thereto appearing elsewhere in this report.
This Quarterly Report on Form 10-Q, 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 "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
described in (i) our Annual Report on Form 10-K for the fiscal year ended
December 31, 2019 including those described under the caption "Risk Factors,"
(ii) our subsequent filings under the Exchange Act and (iii) the risk factors
set forth in this Form 10-Q in Part II, 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 and the direct and
             indirect impact of such measures on our and our tenants' businesses,
             financial condition, results of operation, cash flows,

liquidity and


             performance, and the U.S. and international economy and

economic


             activity generally; 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;

             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

             Report on Form 10-K for the fiscal year ended December 31, 2019 or
             described herein, including those under the caption "Risk Factors."


The risks set forth above are not exhaustive. Other sections of this report may
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 rapidly developing
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
most recent Annual Report on Form 10-K and 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
(REIT) (based on total market capitalization) as of March 31, 2020 in the United
States that develops, owns and manages primarily Class A office properties
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

                                       39

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

Table of Contents



creditworthiness of the tenant, the length of the lease, the rental rate to be
paid at inception and throughout the lease term, the costs of tenant
improvements and other landlord concessions, anticipated operating expenses and
real estate taxes, current and anticipated vacancy, 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 was approximately 8.3 years, as of March 31, 2020, including
leases at our unconsolidated joint ventures. The weighted-average lease term for
our top 20 office tenant leases was approximately 11.9 years. 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


In the first quarter of 2020 macroeconomic conditions were favorable and
positive until COVID-19 began to escalate into a national and global pandemic in
mid-March. In the first two months of the quarter, U.S. GDP remained stable and
job creation remained steady. Starting in March, COVID-19 caused a precipitous
drop in economic activity globally with significant negative impacts on
businesses across the U.S. As the number of unemployment claims rose and the
economy slowed, the Federal Reserve and U.S. Treasury implemented aggressive
monetary and fiscal stimulus policies, including the CARES Act, to bring needed
financial support to small businesses, individuals and industries most affected
by the crisis. Also, the Federal Reserve quickly reduced the federal funds rate
to zero.
The effects of COVID-19 began to have an impact on us and our tenants near the
end of the first quarter. As governments across all of our regions implemented
social distancing and stay-at-home policies, we and our tenants migrated
employees to a work-from-home model. All office properties throughout our
portfolio remain open for tenants, although physical occupancy remains low due
to these measures. By the end of March, construction of our development projects
paused in Boston, New York and San Francisco to comply with municipal social
distancing policies, although construction continued in the Washington, DC
region. Despite the work-stoppages at our development projects, we remain on
schedule to meet all required delivery milestones in our leases and within
budget. Our broad and deep experience as developers extends to our budgeting and
planning, which have left us with ample time in our development schedules.
However, we cannot be certain that work-stoppages will not extend beyond current
expectations or, if they do, that we will meet the milestones and budgets.
Leasing discussions remained active for leases that were in negotiation prior to
COVID-19, but we have experienced a decrease in new leasing requirements and
physical tours are on hold.
Our most important activity at this time is planning for the health and safety
of our tenants and employees and preparing our buildings in accordance with the
policies, protocols and applicable legal requirements in our regions. In early
April 2020, we formed an internal Health Security Task force composed of Boston
Properties' employees, as well as outside experts in health care, industrial
hygiene, cleaning and security. We designed standard operating procedures that
include, but are not limited to, air filtration, water quality, janitorial
products and procedures, social separation and screening during building access
and use of vertical transportation, the use of personal protective equipment,
signage, and management of construction activities. We began communicating the
operating procedures with tenants in early May.

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). Cash rent amounts are
based on all rent billed by us, including all amounts from consolidated
operations and all unconsolidated joint ventures, other than Gateway Commons for
which we do not handle billing.
Our April 2020 rent collections among all tenants were approximately 93%, a
reduction from prior levels as a result of COVID-19, primarily due to certain
retail tenants.  Collections from our office tenants in April remained strong.
During the first quarter of 2020, approximately 87% of the aggregate amount of
our consolidated revenues were derived from office leases. For the month of
April, we collected approximately 97% of our total commercial rent payments due
April 1 from office tenants. In some of these cases, the tenant paid its rent,
but reserved its right to assert that the terms of its lease do not require the
tenant to pay. Office tenants in the flexible office use and
manufacturing/retail industries, which represent 3% and 5% of our office rents,
respectively, present a heightened concern for rent collection, as we collected
approximately 78% and 73%, respectively, from these tenants for the month of
April. Unpaid April rent was approximately $1.3 million and $2.9 million for
flexible office and manufacturing/retail, respectively. In addition, our share
of the accrued rent for tenants in these groups is approximately $3.9 million
and $7.2 million, respectively. For clarity, manufacturing/retail includes
retail and consumer products office tenants.
In addition, during the first quarter of 2020, approximately 7.2% of the
aggregate amount of our consolidated revenues were derived from retail leases.
For the month of April, we collected approximately 36% of our total commercial
rent payments due from retail tenants for rents due April 1. We are actively
working on lease amendments with retail tenants in this category that we believe
have justifiable financial needs.  Of the retail tenants that did not pay rent
for April, our share of the accrued rent balance for these tenants is
approximately $25.1 million.
We continue to analyze our accounts receivable, tenant creditworthiness and
current economic trends to evaluate the adequacy of the collectability of our
tenants' total accounts receivable balances, including lease revenue, and if
considered uncollectible, we will write-off the receivable and accrued rent
balances associated with the leases, and record future lease revenue on a cash
basis.
During 2019, our total parking revenue was approximately $100 million and our
share of total parking revenue from unconsolidated joint ventures was
approximately $13 million. Approximately $40 million of this aggregate amount of
consolidated and unconsolidated parking revenue was derived from hourly/daily
parking. The remainder of the aggregate amount of parking revenue was derived
from monthly parking revenues, some of which are contractual agreements embedded
in our leases, and some are at will individual agreements. In April, with
stay-at-home orders and business closures, we generated minimal hourly/daily
parking revenue and this trend may continue for as long as these stay-at-home
orders and business closures continue.
Approximately 2% of our total revenue in 2019 was from our hotel, the Boston
Marriott Cambridge. The hotel property has been closed since March 22, 2020 and
is currently running at a monthly deficit. It is unclear when the hotel will
open.
As a result of the impact of the current environment, we expect our 2020
revenues to be impacted from (1) lower collections, primarily from our retail
tenants, parking and hotel operators, (2) a slowdown in new leasing activity for
vacant and expiring space and (3) delayed revenue recognition related to tenants
who are currently building out space as a result of construction delays.
Despite the near-term challenges of COVID-19, we remain confident in our ability
to weather the current market downturn and manage our business throughout
uncertain future market conditions.
As a leading developer, owner and manager of marquee Class A office properties
in the U.S., our priorities during and following COVID-19 remain focused on the
following:
•            ensuring tenant satisfaction by keeping our properties safe, open
             and available for occupancy;

• implementing measures to ensure tenant and employee health security;




•            communicating openly with tenants to provide assurance 

before and


             during re-occupancy;


• leasing available space in our in-service and development properties;




•            resuming and completing the construction of our development
             properties as conditions allow;



                                       41

•            continuing and completing the redevelopment and 

repositioning of


             several key properties to increase future revenue and asset values
             over the long-term;


•            maintaining our conservative balance sheet and managing our
             near-term debt maturities;


•            actively managing our operations in a safe, sustainable and
             responsible manner; and

• maintaining discipline in our underwriting of investment opportunities.




Following is an overview of portfolio activity and leasing activity in the first
quarter of 2020, recognizing that both leasing activities and construction
activities had slowed in the majority of our regions by the end of the first
quarter due to COVID-19.
The overall occupancy of our in-service office and retail properties was 92.9%
at March 31, 2020, a slight decrease of 10 basis points as compared to December
31, 2019. During the first quarter of 2020, we signed leases across our
portfolio totaling approximately 702,000 square feet and we commenced revenue
recognition on approximately 995,000 square feet of leases in second generation
space. Of these second generation leases, approximately 727,000 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 93% over the prior leases. The increase in net rental obligations
included the commencement of a retail lease in the New York region that had a
significant impact on net rents. Excluding this lease, increase in net rental
obligations in the first quarter of 2020 was 25%.
A brief overview of each of our markets follows.
Boston
Our Boston central business district ("CBD") in-service portfolio was
approximately 99% leased as of March 31, 2020. During the first quarter of 2020,
we executed approximately 93,000 square feet of leases and had approximately
267,000 square feet of leases commence in the Boston region. Approximately
183,000 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
43% over the prior leases. For the majority of the first quarter of 2020, we
continued development of 100 Causeway Street, an approximately 632,000 net
rentable square foot office tower located in Boston, Massachusetts, of which we
own 50%, that is 95% pre-leased, as of May 5, 2020.
Our approximately 2.0 million square foot in-service office portfolio in
Cambridge was 99.5% leased, as of March 31, 2020. For the majority of the first
quarter of 2020, we continued the development of 325 Main Street at Kendall
Center in Cambridge, Massachusetts, which is 90% pre-leased to a tenant for a
term of 15 years.
In our suburban Waltham/Lexington portfolio, we continued the redevelopment of a
portion of 200 West Street, an approximately 261,000 net rentable square foot
Class A office property in Waltham, Massachusetts. The redevelopment is a
conversion of a portion of the property to laboratory space to meet growing
demand in the life sciences sector.
Construction of our Boston and Cambridge developments/redevelopments has
temporarily stopped to comply with the social distancing policies and directives
of the cities.
Los Angeles
Our Los Angeles ("LA") portfolio is currently focused on West LA and includes an
approximately 1.1 million square foot property, Colorado Center, 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%. We believe both properties provide us
with ample opportunity for future growth, as a majority of the current leases
are at below-market rents. As of March 31, 2020, our LA in-service properties
was approximately 96% leased. Depending on market conditions, we expect to
continue to explore opportunities to increase our presence in the LA market by
seeking investments where our financial, operational, redevelopment and
development expertise provide the opportunity to achieve accretive returns.

New York
As of March 31, 2020, our New York CBD in-service portfolio was approximately
96% leased. In the first quarter of 2020, we commenced approximately 263,000
square feet of leases in the New York region. Of these leases, approximately
143,000 square feet had been vacant for less than one year and represent an
increase in net rental obligations of approximately 205% over the prior leases.
Excluding the commencement of a retail lease that had a significant impact on
leases, the increase in net rental obligations was 3.9%. Although the pace of
new leasing activities in our New York region slowed by the end of the first
quarter due to COVID-19, in April 2020, we signed an approximately 24,000 square
foot lease at 399 Park Avenue bringing the office portion of that property to
100% leased, and we also signed an approximately 27,000 square foot lease at
Times Square Tower with a law firm.
San Francisco
Our San Francisco CBD in-service properties were approximately 98% leased as of
March 31, 2020. During the first quarter of 2020, we commenced approximately
169,000 square feet of leases in the San Francisco region. Of these leases,
approximately 111,000 square feet had been vacant for less than one year and
represent an increase in net rental obligations of approximately 50% over the
prior leases.
In our Silicon Valley portfolio, on February 20, 2020, we completed the
acquisition of land underlying the ground lease at Platform 16 in San Jose.
Platform 16 is a joint venture in which we own 55% and consists of a parcel of
land totaling approximately 5.6 acres that is expected to support the
development of approximately 1.1 million square feet of commercial office space.
On January 28, 2020, the joint venture commenced site preparation work at
Platform 16. Due to the uncertainty related to COVID-19, and in consultation
with our partner, the joint venture has paused construction activities and will
revisit its plans once the economic impact of COVID-19 becomes clearer.
On January 28, 2020, we entered into a joint venture with a partner to own,
operate and develop approximately 1.1 million square feet of existing office and
lab properties in South San Francisco, California, with the opportunity for
approximately 640,000 square feet of additional future development.  Upon
completion, the joint venture is expected to own an approximately 1.7 million
square foot life sciences campus, including a mix of office and lab buildings.
Under the joint venture agreement, we contributed 601, 611 and 651 Gateway
Boulevard, three existing office properties that total approximately 768,000 net
rentable square feet, and developable land for our 50% ownership interest in the
joint venture.  The partner contributed approximately 313,000 square feet of
properties (including one property under construction) consisting of lab, office
and amenity buildings, and developable land and will contribute cash totaling
approximately $69.2 million in the future for its 50% ownership interest in the
joint venture.  As a result of the partner's deferred contribution, we have an
initial approximately 55% interest in the joint venture. The South San Francisco
market has experienced strong demand from companies in the life sciences sector.
Depending on market conditions, we expect this joint venture will allow us to
expand the amount of developable land on the combined site and efficiently
capitalize on tenant demand in the life sciences sector.
Washington, DC
In the Washington, DC region, our focus remains on (1) expanding our development
potential in Reston, Virginia, where demand from technology and cybersecurity
tenants remains strong, (2) divesting of 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 first quarter
of 2020, we commenced approximately 600,000 square feet of leases in the
Washington, DC region. Of these leases, approximately 275,000 square feet had
been vacant for less than one year and represent an increase in net rental
obligations of approximately 13% over the prior leases.
In our Reston, Virginia portfolio, in the first quarter of 2020, we placed in
service 17Fifty Presidents Street, a build-to-suit project with approximately
276,000 net rentable square feet of Class A office space that is 100% leased to
an affiliate of Leidos Holdings, Inc. We also continued development of Reston
Gateway, our mixed-use development project, which will consist of an aggregate
of approximately 4.5 million net rentable square feet. The initial phase is
approximately 1.1 million net rentable square feet, of which approximately 72%
is pre-leased to Fannie Mae. Our Reston, Virginia in-service portfolio was
approximately 87% leased as of March 31, 2020 and continues to be the strongest
submarket in the region.

In the first quarter of 2020, we completed the sale of New Dominion Technology
Park located in Herndon, Virginia for a gross sale price of $256.0 million,
resulting in net proceeds of approximately $254.0 million and reported gain on
sale of approximately $192.3 million for BXP and approximately $197.1 million
for BPLP. New Dominion Technology Park is comprised of two Class A office
properties aggregating approximately 493,000 net rentable square feet.
Our Washington, DC CBD in-service properties were approximately 85% leased, as
of March 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 dispositions of assets.

Development/redevelopment
•          On January 28, 2020, we exercised our option to acquire real property
           at 425 Fourth Street located in San Francisco, California for a
           purchase price totaling approximately $134.1 million. 425 Fourth
           Street is expected to support the development of approximately 804,000
           square feet of primarily commercial office space. There can be no
           assurance that the acquisition will be consummated on the terms
           currently contemplated or at all.


•          On March 26, 2020, we completed and fully placed in-service 17Fifty
           Presidents Street located in Reston, Virginia. 17Fifty

Presidents


           Street is a build-to-suit project with approximately 276,000 net
           rentable square feet of Class A office space that is 100% leased.

Dispositions


•          On January 28, 2020, we entered into a joint venture with a third
           party to own, operate and develop properties at our Gateway Commons
           complex located in South San Francisco, California. We

contributed our


           601, 611 and 651 Gateway properties and development rights with an
           agreed upon value aggregating approximately $350.0 million for our 50%
           interest in the joint venture. 601, 611 and 651 Gateway consist of
           three Class A office properties aggregating approximately

768,000 net


           rentable square feet. The partner contributed three properties 

and


           development rights with an agreed upon value aggregating 

approximately

$280.8 million at closing and will contribute cash totaling
           approximately $69.2 million in the future for its 50% ownership
           interest in the joint venture. As a result of the partner's deferred
           contribution, we have an initial approximately 55% interest in the
           joint venture. Future development projects will be owned 49% by us and
           51% by the partner. We recognized a gain on the retained and sold
           interest in the real estate contributed to the joint venture totaling
           approximately $217.7 million for BXP and $222.4 million for BPLP
           during the three months ended March 31, 2020, within Gains

(Losses) on


           Sales of Real Estate on the respective Consolidated Statements of
           Operations, as the fair value of the real estate exceeded its carrying
           value (See Notes 3 and 5 to the Consolidated Financial

Statements).

• On February 20, 2020, we completed the sale of New Dominion Technology


           Park located in Herndon, Virginia for a gross sale price of

$256.0


           million. Net cash proceeds totaled approximately $254.0 million,
           resulting in a gain on sale of real estate totaling 

approximately

$192.3 million for BXP and approximately $197.1 million for

BPLP. New


           Dominion Technology Park is comprised of two Class A office

properties


           aggregating approximately 493,000 net rentable square feet.


Unconsolidated joint venture activities
•          On January 28, 2020, we entered into a joint venture with a third
           party to own, operate and develop properties at its Gateway Commons
           complex located in South San Francisco, California. We will have a 50%
           interest in the joint venture. See "Dispositions" above for

additional


           information.


• On January 28, 2020, a joint venture in which we have a 55% interest


           commenced development of the first phase of its Platform 16

project


           located in San Jose, California. The first phase of the Platform 

16


           development project consists of an approximately 390,000 net 

rentable


           square foot Class A office building and a below-grade parking 

garage.


           Though the joint venture has completed site preparation work, in
           consultation with our partner, the joint venture has paused
           construction activities and it will revisit its plans once the
           economic impact of COVID-19 becomes clearer. On February 20, 

2020, the


           joint venture acquired the land underlying the ground lease for a
           purchase price totaling approximately $134.8 million. The joint
           venture had previously made a deposit totaling $15.0 million,

which deposit was credited against the purchase price. Platform 16 consists of a
parcel of land totaling approximately 5.6 acres that is expected to support the
development of approximately 1.1 million square feet of commercial office space.
•          On March 18, 2020, a joint venture in which we have a 50% interest
           extended the mortgage loan collateralized by Annapolis Junction
           Building Seven and Building Eight. At the time of the extension, the
           outstanding balance of the loan totaled approximately $34.6 million,
           bore interest at a variable rate equal to LIBOR plus 2.35% per annum
           and matured on March 6, 2020. The extended loan matures on June 30,
           2020. Annapolis Junction Building Seven and Building Eight are Class A
           office properties with approximately 127,000 and 126,000 net rentable
           square feet, respectively, located in Annapolis, Maryland.


Transactions completed subsequent to March 31, 2020 included the following:
•          On April 22, 2020, a joint venture in which we have a 20% interest
           extended the mortgage loan collateralized by Metropolitan Square
           located in Washington, DC. At the time of the extension, the
           outstanding balance of the loan totaled approximately $156.4 million
           and was scheduled to mature on May 5, 2020. The extended loan
           continues to bear interest at a fixed rate of 5.75% per annum and
           matures on August 5, 2020. Metropolitan Square is a Class A office
           property with approximately 654,000 net rentable square feet.

• 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 estimated transaction expenses.


Critical Accounting Policies
Management's Discussion and Analysis of Financial Condition and Results of
Operations discuss our Consolidated Financial Statements, which have been
prepared in accordance with generally accepted accounting principles ("GAAP").
The preparation of these financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and the disclosure of contingent liabilities at the date
of the financial statements and the reported amounts of revenue and expenses
during the reporting period. Certain accounting policies are considered to be
critical accounting policies, as they require management to make assumptions
about matters that are highly uncertain at the time the estimate is made and
changes in accounting estimate are reasonably likely to occur from period to
period. Management bases its estimates and assumptions on historical experience
and current economic conditions. On an on-going basis, management evaluates its
estimates and assumptions including those related to revenue, impairment of
long-lived assets and the allowance for doubtful accounts. Actual results may
differ from those estimates and assumptions.
Our Annual Report on Form 10-K for the year ended December 31, 2019 contains a
discussion of our critical accounting policies, except for our policies
established following the adoption of Accounting Standards Update ("ASU") ASU
2016-13, ASU 2018-13, ASU 2018-17 and ASU 2020-04. The adoption of each of the
pronouncements is discussed in Note 2 to our Consolidated Financial Statements.
Management discusses and reviews our critical accounting policies and
management's judgments and estimates with BXP's Audit Committee.
Results of Operations for the Three Months Ended March 31, 2020 and 2019
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 effect on these parties could
also have a material adverse effect on us. The impact of COVID-19 on our
revenue, in particular lease and parking revenue for the second quarter of 2020
and thereafter, also cannot be determined at present. 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 March 31, 2020 and 2019, we owned or had 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 three months ended
March 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, 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
(losses) from investments in securities, interest and other income, gains
(losses) 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
Quarterly Report on Form 10-Q.
Comparison of the three months ended March 31, 2020 to the three months ended
March 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 140 properties totaling approximately 39.1 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 March 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 March 31, 2020. This table includes a reconciliation from the Same Property
Portfolio to the Total Property Portfolio by also providing information for the
three months ended March 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 49. Residential Net
       Operating Income for the three months ended March 31, 2020 and 2019 is

comprised of Residential Revenue of $9,956 and $7,715 less Residential

Expenses of $4,064 and $3,774, respectively. Hotel Net Operating Income

for the three months ended March 31, 2020 and 2019 is comprised of Hotel

Revenue of $6,825 and $8,938 less Hotel Expenses of $6,821 and $7,863,


       respectively, per the Consolidated Statements of Operations.

Same Property Portfolio
Lease Revenue (Excluding Termination Income)
Lease revenue from the Same Property Portfolio increased by approximately $27.8
million for the three months ended March 31, 2020 compared to 2019. The increase
was a result of our average revenue per square foot increasing by approximately
$2.32, contributing approximately $22.4 million, and an approximately $5.4
million increase due to our average occupancy increasing from 93.6% to 94.4%.
Upon the adoption of Accounting Standards Codification ("ASC") 842 - Leases, any
write-off for bad debt, including accrued rent, will be shown as a reduction to
lease revenue. However, the degree to which our tenants' businesses are
negatively impacted by COVID-19 could result in a reduction in our cash flows or
require that we write-off a tenant's accrued rent balance 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 $4.6 million for the three months
ended March 31, 2020 compared to 2019.
Termination income for the three months ended March 31, 2020 related to 15
tenants across the Same Property Portfolio and totaled approximately $2.4
million, which was primarily related to tenants that terminated leases early in
New York City and the Boston region.
Termination income for the three months ended March 31, 2019 related to 11
tenants across the Same Property Portfolio and totaled approximately $7.0
million, of which approximately $4.9 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 $0.9 million for the three
months ended March 31, 2020 compared to 2019, primarily due to a decrease in
transient parking. Due to COVID-19, we expect to see a decrease in parking
revenue, for fiscal year 2020, as a result of mandatory business closures and
"stay-at-home" orders. See Item 1A: "Risk Factors" for additional details.
Parking revenue generally consists of two primary components: revenue from
monthly passes and hourly/daily parking revenue. During 2019, total parking
revenue was approximately $100 million and our share of total parking revenue
from unconsolidated joint ventures was approximately $13 million. Approximately
$40 million of this aggregate amount of consolidated and unconsolidated parking
revenue was derived from hourly/daily parking. In April,
with stay-at-home orders and business closures, we generated minimal
hourly/daily parking revenue and this trend may continue for as long as
these stay-at-home orders and business closures continue. 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 increased by
approximately $6.1 million, or 2.5%, for the three months ended March 31, 2020
compared to 2019, due primarily to increases in real estate taxes and other real
estate operating expenses of approximately $5.3 million, or 4.2%, and $0.8
million, or 0.7%, respectively. The increase in real estate taxes was primarily
experienced in the New York CBD properties.
Properties Acquired Portfolio
The table below lists the properties acquired between January 1, 2019 and
March 31, 2020. Rental revenue and real estate operating expenses increased by
approximately $3.6 million and $1.5 million, respectively, for the three months
ended March 31, 2020 compared to 2019, as detailed below.

_______________

(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 $1.1 million for the three months ended March 31, 2020 compared
to 2019.
The following reflects our occupancy and rate information for the Boston
Marriott Cambridge hotel for the three months ended March 31, 2020 and 2019.

Occupancy                59.6 %       80.2 %      (25.7 )%
Average daily rate   $ 211.35     $ 221.39         (4.5 )%
REVPAR               $ 126.00     $ 177.63        (29.1 )%



As a result of COVID-19, the Boston Marriott Cambridge was closed in March 2020
and is running at a monthly deficit. We do not know when the hotel will re-open
and its closure will have a material adverse effect on the hotel's contribution
to our results of operations during the closure. See Item 1A: "Risk Factors" for
additional details.
Other Operating Revenue and Expense Items
Development and Management Services Revenue
Development and management services revenue decreased by approximately $1.4
million for the three months ended March 31, 2020 compared to 2019. Development
services revenue decreased by approximately $1.5 million while management
services revenue increased by approximately $0.1 million. The decrease in
development services revenue was primarily related to a decrease of
approximately $2.7 million in development fees and fees associated with tenant
improvement projects earned in the Boston region offset by an increase of $0.6
million in development fees earned in the San Francisco region and an increase
of $0.6 million in development fees associated with a tenant improvement project
earned in the Washington, DC region. The increase in management services revenue
was primarily related to an increase in property management fees earned from the
Los Angeles region.
General and Administrative Expense
General and administrative expense decreased by approximately $5.3 million for
the three months ended March 31, 2020 compared to 2019 primarily due to a
decrease in compensation expense. The decrease in compensation expense was
related to an approximately $8.4 million decrease in the value of our deferred
compensation plan partially offset by an approximately $3.1 million increase in
other compensation expense, which includes the expense associated with our
equity compensation programs, which includes the acceleration of amortization
that occurred for employees that reached a certain age and number of years of
service and therefore became vested in these awards sooner.
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 three months ended March 31, 2020 and 2019 were
approximately $2.8 million and $2.9 million, respectively. These costs are not
included in the general and administrative expenses discussed above.
Transaction Costs
Transaction costs increased by approximately $0.2 million for the three months
ended March 31, 2020 compared to 2019 due primarily to transaction costs related
to 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
Quarterly Report on Form 10-Q.

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.
Other Income and Expense Items
Income (Loss) from Unconsolidated Joint Ventures
For the three months ended March 31, 2020 compared to 2019, income (loss) from
unconsolidated joint ventures decreased by approximately $0.6 million primarily
due to the addition of our Gateway Commons joint venture and the partial placing
in-service of the Hub50House joint venture in South San Francisco, CA and
Boston, MA, respectively. These joint ventures reduced our net income by
approximately $1.4 million for the three months ended March 31, 2020. At March
31, 2020, the Hub50House was only 28% leased and is not expected to be
stabilized until the first quarter of 2022. The decrease in net income from the
Gateway Commons joint venture was primarily related to depreciation and
amortization. These decreases were offset by an approximately $0.8 million
increase related to our share of net income from our other unconsolidated joint
ventures.

Gains (Losses) 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 Quarterly Report on

      amounts from sales of real estate occurring in the prior year.

      recognized during the three months ended March 31, 2019 related to loss
      amounts from sales of real estate occurring in prior years.


Interest and Other Income
Interest and other income decreased by approximately $0.7 million for the three
months ended March 31, 2020 compared to 2019 due primarily to a decrease in
interest rates.
Gains (Losses) from Investments in Securities
Gains (losses) from investments in securities for the three months ended
March 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 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 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 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 (losses) from investments
in securities. During the three months ended March 31, 2020 and 2019, we
recognized gains (losses) of approximately $(5.4) million and $3.0 million,
respectively, on these investments. By comparison, our general and
administrative expense increased (decreased) by approximately $(5.4) million and
$3.0 million during the three months ended March 31, 2020 and 2019,
respectively, as a result of increases (decreases) in our liability under our
deferred compensation plans that was associated with the performance of the
specific investments selected by officers and 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

                                       57

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 Quarterly Report on Form 10-Q.
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.
Interest Expense
Interest expense increased by approximately $0.6 million for the three months
ended March 31, 2020 compared to 2019, as detailed below.

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 three
months ended March 31, 2020 and 2019 was approximately $14.1 million and $11.8
million, respectively. These costs are not included in the interest expense
referenced above.
At March 31, 2020, our outstanding 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 and Revolving Facility had $500.0 million
and $250.0 million outstanding as of March 31, 2020, respectively. For a summary
of our consolidated debt as of March 31, 2020 and March 31, 2019 refer to the
heading "Liquidity and Capital Resources-Capitalization-Debt Financing" within
"Item 2-Management's Discussion and Analysis of Financial Condition and Results
of Operations."

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 12 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.
Noncontrolling Interests in Property Partnerships

_______________

(1) On April 1, 2019, we acquired our partner's 5% interest and subsequently


      own 100%.


(2)   The decrease was primarily due to a decrease in lease revenue from our
      tenants.


(3)   The increase was primarily due to an increase in lease revenue from our
      tenants.


Noncontrolling Interest-Common Units of the Operating Partnership
For BXP, noncontrolling interest-common units of the Operating Partnership
increased by approximately $45.9 million for the three months ended March 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;

• 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.

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 and other 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.

Table of Contents



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 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. For example, we
may experience a decrease in cash rent collections resulting from restrictions
implemented to limit the spread of COVID-19, including delays in tenant
improvements and decreases in parking and hotel revenue. In turn, these changes
could adversely affect our ability to fund operating expenses, dividends and
distributions, debt service payments, maintenance and repositioning capital
expenditures and tenant improvements. In addition, a 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 and unsecured senior
notes.
Our primary uses of capital will be the completion of our current and committed
development and redevelopment projects. As of March 31, 2020, our share of the
remaining development and redevelopment costs that we expect to fund through
2024 is approximately $1.2 billion.
As of May 5, 2020, we have approximately $1.6 billion of cash and cash
equivalents, of which approximately $124 million is attributable to our
consolidated joint venture partners, as well as approximately $151 million held
in escrow for 1031 exchanges. Our cash and cash equivalents balance includes the
proceeds from BPLP's issuance of $1.25 billion of 3.250% unsecured senior notes
due 2031, which generated net proceeds of approximately $1.24 billion. We used
$250.0 million of the net proceeds from this offering for the repayment of
borrowings outstanding under the Revolving Facility. In addition, during the
first quarter of 2020, we enhanced our liquidity with the sale of our New
Dominion Technology Park property located in Herndon, Virginia, which generated
net cash proceeds of approximately $254 million.
Although the full extent to which COVID-19 impacts our liquidity and capital
resources will depend on future developments, which are highly uncertain and
cannot be predicted with confidence at this time, we believe that our strong
liquidity, including, as of May 5, 2020, the approximately $1.5 billion
available under the Revolving Facility, and proceeds from debt financings and
asset sales will provide sufficient liquidity to fund our remaining capital
requirements on existing development and redevelopment projects, fund pending
new developments and still be able to act opportunistically on attractive
investment opportunities.
We have not sold any shares under BXP's $600.0 million at the market (ATM)
program and intend to renew the program prior to its expiration in June 2020.
We may seek to enhance our liquidity to provide sufficient capacity to fund our
remaining capital requirements on existing development/redevelopment projects,
fund our foreseeable potential development activity, pursue additional
attractive investment opportunities and refinance or repay indebtedness. Our
unconsolidated joint ventures have approximately $498.8 million of debt maturing
in 2020, of which our share is approximately $202.5 million. We have no debt
maturing until BPLP's $850 million of 4.125% senior unsecured notes mature in
May 2021, and we intend to continue to evaluate the costs associated with an
early refinancing or redemption of all or a portion of this maturity. 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 BPLP's 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

                                       62

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

Table of Contents



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, 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
$858.6 million and $432.3 million at March 31, 2020 and 2019, respectively,
representing an increase of approximately $426.3 million. The following table
sets forth changes in cash flows:

255,900




Our principal source of cash flow is related to the operation of our properties.
The weighted-average term of our in-place tenant leases, including our
unconsolidated joint ventures, is approximately 8.3 years 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 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 three months ended March 31,
2020 consisted primarily of development projects, building and tenant
improvements and capital contributions to unconsolidated joint ventures,
partially offset by the proceeds from the sales of real estate. Cash

$ (223,515 )

Cash used in investing activities changed primarily due to the following:



(1)    On January 10, 2019, we acquired land parcels at our Carnegie Center
       property located in Princeton, New Jersey for a gross purchase price of
       approximately $51.5 million, which includes an aggregate of
       approximately $8.6 million of additional amounts that are payable in the

future to the seller upon the development or sale of each of the parcels.


       The land parcels will support approximately 1.7 million square feet of
       development.


(2)    Construction in progress for the three months ended March 31, 2020

includes ongoing expenditures associated with 17Fifty Presidents Street,

which was completed and placed in-service during the three months ended

March 31, 2020 and 20 CityPoint, which was partially placed in-service


       during the year ended December 31, 2019. In addition, we incurred costs
       associated with our continued development/redevelopment of One Five Nine
       East 53rd Street, Reston Gateway, 2100 Pennsylvania Avenue, 200 West
       Street, The Skylyne and 325 Main Street.


Construction in progress for the three months ended March 31, 2019 includes
ongoing expenditures associated with Salesforce Tower, which was placed
in-service during the year ended December 31, 2018. In addition, we incurred
costs associated with our continued development/redevelopment of One Five Nine
East 53rd Street, 145 Broadway, 20 CityPoint, 17Fifty Presidents Street, Reston
Gateway and The Skylyne.
(3)    On February 20, 2020, we completed the sale of New Dominion Technology

Park located in Herndon, Virginia for a gross sale price of $256.0

million. Net cash proceeds totaled approximately $254.0 million, resulting

in a gain on sale of real estate totaling approximately $192.3 million for

BXP and approximately $197.1 million for BPLP. New Dominion Technology

Park is comprised of two Class A office properties aggregating

approximately 493,000 net rentable square feet.




On January 24, 2019, we completed the sale of our 2600 Tower Oaks Boulevard
property located in Rockville, Maryland for a gross sale price of approximately
$22.7 million. Net cash proceeds totaled approximately $21.4 million, resulting
in a loss on sale of real estate totaling approximately $0.6 million. 2600 Tower
Oaks Boulevard is an approximately 179,000 net rentable square foot Class A
office property.
(4)    Capital contributions to unconsolidated joint ventures for the three

months ended March 31, 2020 consisted primarily of cash contributions of

approximately $64.5 million, $16.8 million and $4.0 million to our

Platform 16, 3 Hudson Boulevard and Metropolitan Square joint ventures,

respectively.




Capital contributions to unconsolidated joint ventures for the three months
ended March 31, 2019 consisted primarily of cash contributions of approximately
$23.3 million to our 100 Causeway Street joint venture.
Cash provided by financing activities for the three months ended March 31, 2020
totaled approximately $65.3 million. This consisted primarily of the proceeds
from borrowing under the Revolving Facility, partially offset by the payment of
our regular dividends and distributions to our shareholders and unitholders.
Future debt payments are discussed below under the heading "Capitalization-Debt
Financing."

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
March 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 March 31, 2020.
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.

Debt Financing
As of March 31, 2020, we had approximately $12.1 billion of outstanding
consolidated indebtedness, representing approximately 42.73% of our Consolidated
Market Capitalization as calculated above consisting of approximately (1) $8.4
billion (net of discount and deferred financing fees) in publicly traded
unsecured senior notes having a GAAP weighted-average interest rate of 3.76% per
annum and maturities in 2021 through 2030 (See Note 12 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
3.90% per annum and weighted-average term of 6.1 years and (3) $749.1 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 82.5 basis points and 90 basis
points, respectively, and (2) the facility fee on the Revolving Facility
commitment is 0.125% per annum.

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

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 March 31, 2020 credit
rating and matures on April 24, 2022.
As of March 31, 2020, BPLP had $500.0 million of borrowings outstanding under
its Delayed Draw Facility, $250.0 million borrowings under its Revolving
Facility and letters of credit totaling approximately $2.5 million outstanding
with the ability to borrow approximately $1.2 billion under the Revolving
Facility. As of May 5, 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.

_______________


(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 March 31, 2020, the maximum

funding obligation under the guarantee was approximately $57.1 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 6 to the Consolidated


       Financial Statements).


(5)    This property is owned by a consolidated entity in which we have a 55%
       interest.


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 5 to the Consolidated Financial Statements.
At March 31, 2020, the aggregate carrying amount of debt, including both our and
our partners' share, incurred by these ventures was approximately $2.3 billion
(of which our proportionate share is approximately $1.0 billion). The table
below summarizes the outstanding debt of these joint venture properties at
March 31, 2020. In addition to other guarantees specifically noted in the table,
we have agreed to customary environmental indemnifications and nonrecourse
carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) as
well as the completion of development projects on certain of the loans.

State and Local Tax Matters
Because BXP is organized and qualifies as a REIT, it is generally not subject to
federal income taxes, but is subject to certain state and local taxes. In the
normal course of business, certain entities through which we own real estate
either have undergone, or are currently undergoing, tax audits or other
inquiries. Although we believe that we have substantial arguments in favor of
our position in the ongoing audits, in some instances there is no controlling
precedent or interpretive guidance on the specific point at issue. Collectively,
tax deficiency notices received to date from the jurisdictions conducting the
ongoing audits have not been material. However, there can be no assurance that
future audits will not occur with increased frequency or that the ultimate
result of such audits will not have a material adverse effect on our results of
operations.
Insurance
For information concerning our insurance program, see Note 6 to the Consolidated
Financial Statements.
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, has
improved the understanding of operating results of REITs among the investing
public and has helped 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 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.

During the three months ended March 31, 2020, we paid approximately $81.9
million to fund tenant-related obligations, including tenant improvements and
leasing commissions.
In addition, during the three months ended March 31, 2020, we and our
unconsolidated joint venture partners incurred approximately $36 million of new
tenant-related obligations associated with approximately 702,000 square feet of
second generation leases, or approximately $52 per square foot. We did not sign
any first generation leases. The tenant-related obligations for the development
properties are included within the projects' "Estimated Total Investment"
referred to in "Item 2-Management's Discussion and Analysis of Financial
Condition and Results of Operations-Liquidity and Capital Resources."
ITEM 3-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 March 31,
2020. As of March 31, 2020, approximately $11.3 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 March 31, 2020, the weighted-average
interest rate on our variable rate debt was LIBOR plus 0.85% (2.07%) 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
discussion concerning our unconsolidated joint venture debt, see Note 5 to the
Consolidated Financial Statements and "Item 2-Management's Discussion and
Analysis of Financial Condition and Results of
Operations-Capitalization-Off-Balance Sheet Arrangements-Joint Venture
Indebtedness."

At March 31, 2020, the weighted-average coupon/stated rates on the fixed rate
debt stated above was 3.69% per annum. At March 31, 2020, our outstanding
variable rate debt based on LIBOR totaled approximately $750.0 million. At
March 31, 2020, the coupon/stated rate on our variable rate debt was
approximately 2.07% per annum. If market interest rates on our variable rate
debt had been 100 basis points greater, total interest expense would have
increased approximately $1.9 million for the three months ended March 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. 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.
