The following discussion relates to our consolidated financial statements and
should be read in conjunction with the financial statements and notes thereto
appearing elsewhere in this report. The results of operations discussion is
combined for the Company and the Operating Partnership because there are no
material differences in the results of operations between the two reporting
entities.

Forward-Looking Statements



Statements contained in this "Item 2. Management's Discussion and Analysis of
Financial Condition and Results of Operations" that are not historical facts may
be forward-looking statements. Forward-looking statements include, among other
things, statements or information concerning our plans, objectives, capital
resources, portfolio performance, results of operations, projected future
occupancy and rental rates, lease expirations, debt maturities, potential
investments, strategies such as capital recycling, development and redevelopment
activity, projected construction costs, projected construction commencement and
completion dates, projected square footage of space that could be constructed on
undeveloped land that we own, projected rentable square footage of or number of
units in properties under construction or in the development pipeline,
anticipated proceeds from capital recycling activity or other dispositions and
anticipated dates of those activities or dispositions, projected increases in
the value of properties, dispositions, future executive incentive compensation,
pending, potential or proposed acquisitions, plans to grow our Net Operating
Income and FFO, our ability to re-lease properties at or above current market
rates, anticipated market conditions and demographics and other forward-looking
financial data, as well as the discussion in "-Factors That May Influence Future
Results of Operations," "-Liquidity and Capital Resource of the Company," and
"-Liquidity and Capital Resources of the Operating Partnership." Forward-looking
statements can be identified by the use of words such as "believes," "expects,"
"projects," "may," "will," "should," "seeks," "approximately," "intends,"
"plans," "pro forma," "estimates" or "anticipates" and the negative of these
words and phrases and similar expressions that do not relate to historical
matters. Forward-looking statements are based on our current expectations,
beliefs and assumptions, and are not guarantees of future performance.
Forward-looking statements are inherently subject to uncertainties, risks,
changes in circumstances, trends and factors that are difficult to predict, many
of which are outside of our control. Accordingly, actual performance, results
and events may vary materially from those indicated or implied in the
forward-looking statements, and you should not rely on the forward-looking
statements as predictions of future performance, results or events. Numerous
factors could cause actual future performance, results and events to differ
materially from those indicated in the forward-looking statements, including,
among others: global market and general economic conditions and their effect on
our liquidity and financial conditions and those of our tenants; adverse
economic or real estate conditions generally, and specifically, in the States of
California, Texas and Washington; risks associated with our investment in real
estate assets, which are illiquid and with trends in the real estate industry;
defaults on or non-renewal of leases by tenants; any significant downturn in
tenants' businesses; our ability to re-lease property at or above current market
rates; costs to comply with government regulations, including environmental
remediation; the availability of cash for distribution and debt service and
exposure to risk of default under debt obligations; increases in interest rates
and our ability to manage interest rate exposure; the availability of financing
on attractive terms or at all, which may adversely impact our future interest
expense and our ability to pursue development, redevelopment and acquisition
opportunities and refinance existing debt; a decline in real estate asset
valuations, which may limit our ability to dispose of assets at attractive
prices or obtain or maintain debt financing, and which may result in write-offs
or impairment charges; significant competition, which may decrease the occupancy
and rental rates of properties; potential losses that may not be covered by
insurance; the ability to successfully complete acquisitions and dispositions on
announced terms; the ability to successfully operate acquired, developed and
redeveloped properties; the ability to successfully complete development and
redevelopment projects on schedule and within budgeted amounts; delays or
refusals in obtaining all necessary zoning, land use and other required
entitlements, governmental permits and authorizations for our development and
redevelopment properties; increases in anticipated capital expenditures, tenant
improvement and/or leasing costs; defaults on leases for land on which some of
our properties are located; adverse changes to, or enactment or implementations
of, tax laws or other applicable laws, regulations or legislation, as well as
business and consumer reactions to such changes; risks associated with joint
venture investments, including our lack of sole decision-making authority, our
reliance on co-venturers' financial condition and disputes between us and our
co-venturers; environmental uncertainties and risks related to natural
disasters; our ability to maintain our status as a REIT; and uncertainties
regarding the impact of the COVID-19 pandemic, and restrictions intended to
prevent its spread, on our business and the economy generally. The factors
included in this report are not exhaustive and additional factors could
adversely affect our business and financial performance. For a discussion of
additional factors that could materially adversely affect the Company's and the
Operating Partnership's business and financial performance, see the discussion
below, as well as in "Part I, Item 1A. Risk Factors" and "Part II, Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations" in the Company's and the Operating Partnership's annual report on

SEC. All forward-looking statements are based on information that was available
and speak only as of the dates on which they were made. We assume no obligation
to update any forward-looking statement that becomes untrue because of
subsequent events, new information or otherwise, except to the extent we are
required to do so in connection with our ongoing requirements under federal

Overview and Background



We are a self-administered REIT active in premier office and mixed-use
submarkets in the United States. We own, develop, acquire and manage real estate
assets, consisting primarily of Class A properties in Greater Los Angeles,
San Diego County, the San Francisco Bay Area, the Pacific Northwest and Austin,
Texas, which we believe have strategic advantages and strong barriers to entry.
We own our interests in all of our real properties through the Operating
Partnership and generally conduct substantially all of our operations through
the Operating Partnership. We owned an approximate 99.0%, 99.0%, and 98.3%
general partnership interest in the Operating Partnership as of June 30, 2021,
December 31, 2020 and June 30, 2020. As of June 30, 2021, all of our properties
are held in fee except for the fifteen office buildings that are held subject to
long-term ground leases for the land.

COVID-19 Response



In accordance with local and state government guidance and social distancing
recommendations, the majority of our employees worked remotely beginning in
March 2020. Our employees began transitioning back to the office during the
three months ended March 31, 2021 and as of June 30, 2021, all of our employees
have returned to our offices on a full-time basis.

Since March 2020, we have been highly focused on 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.
We hold our occupants' health at the highest level of importance and have taken
extensive steps to facilitate safe work environments. We engaged an industrial
hygienist to assist us in designing new standard operating procedures for our
buildings that include, but are not limited to, air filtration, water quality,
janitorial products and procedures, social separation and screening during
building access and elevator use, the use of personal protective equipment,
signage, and management of construction activities. Our buildings have remained
open to tenants and we have begun to see certain tenants returning to the
workplace. We have been in communication with tenants regarding return to work
protocols and safety measures, which meet or exceed local and state government
guidelines. Our properties received the highest level of pandemic preparedness
review through a third-party who verified that all recommended CDC and WHO
measures have been successfully implemented, including on-site air, water and
germ testing.

We implemented a rent relief program for the majority of our retail tenants
whereby we deferred rent from April 2020 to June 2021 in exchange for an
extension of their current lease term for an equivalent number of months at
future rental rates. We are no longer offering rent relief to the majority of
our retail tenants and we will evaluate any future retail rent relief requests
on a specific case by case basis and only consider those which have a
justifiable financial basis. Additionally, the form of relief provided to retail
tenants may vary in the future. We did not create a rent relief program for our
office tenants. Instead, we evaluate office rent relief requests on a specific
case by case basis and only consider those which have a justifiable financial
basis. For residential tenants, deferrals of gross rent billings have been
extended in accordance with the applicable local orders, which often require
repayment within 12 months if such local ordinances are not extended.

We analyze our total lease receivable balances, tenant creditworthiness,
specific industry trends and conditions, and current economic trends and
conditions in order to evaluate whether we believe substantially all of the
amounts due under a tenant's lease agreement are deemed probable of collection
over the term of the lease. For leases that are deemed probable of collection,
revenue continues to be recorded on a straight-line basis over the lease term.
For leases that are deemed not probable of collection, revenue is recorded as
the lesser of (i) the amount that would be recognized on a straight-line basis
or (ii) cash that has been received from the tenant, with any tenant and
deferred rent receivable balances charged as a direct write-off against rental
income in the period of the change in the collectability determination.

Deferrals of gross rent billings that have been extended to office and retail
tenants during the period have been formalized by the execution of lease
amendments that generally provide for repayment of deferred amounts through an
extension of the lease term by an equivalent period of months to the deferral
period. Not all tenant relief requests will ultimately result in lease
amendments and we have not relinquished our contractual rights under our lease
agreements where rent concessions have not yet been granted. Our rent
collections and rent relief requests to-date may not be indicative of
collections, concessions or requests in future periods.

                                       28
--------------------------------------------------------------------------------

For the three months ended June 30, 2021, we collected approximately 97% of our
gross rent billings, which is consistent with our 2020 collections. Gross rent
billings represents the total contractual base rent (including tenant
direct-billed parking) and CAM billings before any COVID-19 related rent
concessions for the three months ended June 30, 2021. We are continuing to
monitor the potential impact of the COVID-19 pandemic, and restrictions intended
to prevent its spread, on occupancy, rental rates and rent collections. Although
we are and will continue to be actively engaged in rent collection efforts
related to uncollected rent for such period, as well as working with certain
tenants who have requested rent deferrals, we can provide no assurance that such
efforts or our efforts in future periods will be successful, particularly in the
event that the COVID-19 pandemic, and restrictions intended to prevent its
spread, continue for a prolonged period. Several vaccines for COVID-19 have
received emergency use authorization from the FDA and are currently being
administered across the country. Despite growing vaccination rates, we believe
COVID-19 will continue to impact the normal operations of our tenants. The
continued impact of the pandemic on our and our tenants' businesses is largely
dependent on efforts to stem the spread of COVID-19, including governmental
efforts to distribute vaccines and overall vaccination rates in the areas in
which we own properties and/or have development projects. Refer to "Part I, Item
IA. Risk Factors" in our annual report on Form 10-K for the year ended December
31, 2020 for additional information about the potential impact of the COVID-19
pandemic, and restrictions intended to prevent its spread, on our business,
financial condition, results of operations, cash flows, liquidity and ability to
satisfy our debt service obligations and to pay dividends and distributions to
security holders.

Factors That May Influence Future Results of Operations

Development Program



We believe that a portion of our long-term future growth will continue to come
from the completion of our in-process development projects and, subject to
market conditions, executing on our future development pipeline, including
expanding entitlements. Over the past several years, we increased our focus on
development opportunities and expanded our future development pipeline through
targeted acquisitions of development opportunities on the West Coast and in June
2021 we expanded into Austin, Texas through our acquisition of the Indeed Tower,
which is in the tenant improvement phase.

We have a proactive planning process by which we continually evaluate the size,
timing, costs and scope of our development program and, as necessary, scale
activity to reflect the economic conditions and the real estate fundamentals
that exist in our submarkets. We expect to execute on our development program
with prudence and will be pursuing opportunities with attractive economic
returns in strategic locations with proximity to public transportation or
transportation access and retail amenities and in markets with strong
fundamentals and visible demand. We plan to develop in phases, as appropriate,
and we generally favor starting projects with pre-leasing activity.

Consistent with 2020, our development portfolio was largely unaffected by the
COVID-19 pandemic during the six months ended June 30, 2021; however, the
COVID-19 pandemic, and future restrictions intended to prevent its spread if
case rates surge again, may cause delays or increase costs associated with
building materials or construction services necessary for construction which
could adversely impact our ability to continue or complete construction as
planned, on budget or at all for our development projects, and may delay the
start of construction on our future development pipeline projects. Refer to
"Part I, Item IA. Risk Factors" in our annual report on Form 10-K for the year
ended December 31, 2020 for additional information about the potential impact of
the COVID-19 pandemic, and restrictions intended to prevent its spread, on our
business, financial condition, results of operations, cash flows, liquidity and
ability to satisfy our debt service obligations and to pay dividends and
distributions to security holders.

Stabilized Development Projects

During the six months ended June 30, 2021, we completed and added the following projects to our stabilized portfolio:



•9455 Towne Centre Drive, University Towne Center, San Diego, California. In
March 2019, we commenced construction on this project, which totals
approximately 160,444 square feet of office space at a total estimated
investment of $95.0 million. The project is 100% leased to a Fortune 50 publicly
traded company. We completed construction and commenced revenue recognition
during the three months ended March 31, 2021.

•12860 El Camino Real (One Paseo - Office Building 1), Del Mar, San Diego,
California. We commenced construction on the office component of this project in
December 2018, which encompasses 92,042 square feet of office space at a total
estimated investment of $65.0 million. We completed construction on the building
in June 2020. At June 30, 2021, the building was 100% leased and we had
commenced revenue recognition on approximately 82% of the building.

•Jardine, Hollywood, California. We commenced construction on the residential
component of this project in December 2018, which encompasses 193 residential
units at a total estimated investment of $185.0 million. We completed
construction and commenced revenue recognition during the three months ended
June 30, 2021.

In-Process Development Projects - Tenant Improvement

As of June 30, 2021, the following projects were in the tenant improvement phase:



•333 Dexter, South Lake Union, Seattle, Washington. We commenced construction on
this project in June 2017. This project encompasses approximately 635,000 square
feet of office space at a total estimated investment of $410.0 million and 100%
of the project is leased to a Fortune 50 publicly traded company. In June 2020,
we completed construction and commenced revenue recognition on the first phase
of the project, representing approximately 49% of the project. The remaining two
phases are currently expected to reach stabilization in the second half of 2022.

•One Paseo - Office (Building 2), Del Mar, San Diego, California. We commenced
construction on the office component of this project in December 2018, which
encompasses 195,000 square feet of office space at a total estimated investment
of $145.0 million. At June 30, 2021, the building was 100% leased. We completed
construction in June 2020 and as of the date of this report, we have commenced
revenue recognition on approximately 89% of the project. We currently expect the
project to reach stabilization in the third quarter of 2021.

•Kilroy Oyster Point (Phase 1), South San Francisco, California. In March 2019,
we commenced construction on Phase 1 of this 39-acre life science campus
situated on the waterfront in South San Francisco. This first phase encompasses
approximately 656,000 square feet of office space at a total estimated
investment of $570.0 million and is 100% leased to two tenants. We currently
expect this project to reach stabilization in the fourth quarter of 2021.

•Indeed Tower, Austin CBD, Austin, Texas. We acquired this project upon
core/shell completion in June 2021. This project encompasses approximately
734,000 square feet of office space at a total estimated investment of $680.0
million and is 57% leased to four tenants with 42% of the space leased to
Indeed.com through 2034. We currently expect this project to reach stabilization
in the fourth quarter of 2022.

In-Process Development Projects - Under Construction

As of June 30, 2021, we had two projects in our in-process development pipeline that were under construction:



•2100 Kettner, Little Italy, San Diego, California. We commenced construction on
this project in September 2019. This project is comprised of approximately
235,000 square feet of office space for a total estimated investment of $140.0
million. We currently expect this project to progress to the tenant improvement
phase in the third quarter of 2021.

•Kilroy Oyster Point (Phase 2), South San Francisco, California. In June 2021,
we commenced construction on Phase 2 of this 39-acre life science campus
situated on the waterfront in South San Francisco. The second phase encompasses
approximately 875,000 square feet of office space at a total estimated
investment of $940.0 million.

                                       30
--------------------------------------------------------------------------------

In-Process Development Projects - Committed

As of June 30, 2021, the following project was committed for construction:



•9514 Towne Centre Drive, University Towne Center, San Diego, California. We
expect to commence construction on this project during the fourth quarter of
2021, which is comprised of approximately 71,000 square feet of office space at
a total estimated investment of $60.0 million. This project is currently
committed with an executed definitive agreement for 100% of the building.

Future Development Pipeline



As of June 30, 2021, our future development pipeline included six future
projects located in Greater Seattle, the San Francisco Bay Area and San Diego
County with an aggregate cost basis of approximately $1.0 billion at which we
believe we could develop more than 5.5 million rentable square feet for a total
estimated investment of approximately $5.0 billion to $7.0 billion, depending on
successfully obtaining entitlements and market conditions.

The following table sets forth information about our future development
pipeline.
                                                                                                                 Total Costs

(1)The developable square feet and scope of projects could change materially
from estimated data provided due to one or more of the following: any
significant changes in the economy, market conditions, our markets, tenant

(2)Represents cash paid and costs incurred, including accrued liabilities in
accordance with GAAP, as of June 30, 2021.

Fluctuations in our development activities could cause fluctuations in the
average development asset balances qualifying for interest and other carrying
cost and internal cost capitalization in future periods. During the three and
six months ended June 30, 2021, we capitalized interest on in-process
development projects and future development pipeline projects with an average
aggregate cost basis of approximately $1.8 billion, as it was determined these
projects qualified for interest and other carrying cost capitalization under
GAAP. During the three and six months ended June 30, 2020, we capitalized
interest on in-process development projects and future development pipeline
projects with an average aggregate cost basis of approximately $2.1 billion and
$2.2 billion, respectively, as it was determined these projects qualified for
interest and other carrying cost capitalization under GAAP. In the event of an
extended cessation of development activities, such projects may potentially no
longer qualify for capitalization of interest or other carrying costs. However,
a cessation of development activities caused by events outside of our control,
such as those as a result of government restrictions aimed at stopping the
spread of COVID-19, would not impact our ability to capitalize interest and
other carrying costs. For the three and six months ended June 30, 2021, we
capitalized $18.1 million and $35.0 million, respectively, of interest to our
qualifying development projects. For the three and six months ended June 30,
2020, we capitalized $20.5 million and $41.9 million, respectively, of interest
to our qualifying development projects. For the three and six months ended June
30, 2021, we capitalized $4.9 million and $10.4 million, respectively, of
internal costs to our qualifying development projects. For the three and six
months ended June 30, 2020, we capitalized $6.2 million and $11.3 million,
respectively, of internal costs to our qualifying development projects.

Capital Recycling Program. We continuously evaluate opportunities for the
potential disposition of non-core properties and undeveloped land in our
portfolio or the formation of strategic ventures with the intent of recycling
the proceeds generated into capital used to fund new operating and development
acquisitions, to finance development and redevelopment expenditures, to repay
long-term debt and for other general corporate purposes. As part of this
strategy, we attempt to enter into Section 1031 Exchanges and other tax deferred
transaction structures, when possible, to defer some or all of the taxable gains
on the sales, if
                                       31
--------------------------------------------------------------------------------

any, for federal and state income tax purposes. See the "Liquidity and Capital
Resources of the Operating Partnership - Liquidity Sources" section for further
discussion of our capital recycling activities.

In connection with our capital recycling strategy, during the six months ended
June 30, 2021, we completed the sale of one operating property in San Francisco,
California to an unaffiliated third party for gross proceeds of $1.08 billion,
or approximately $1,440 per square foot. A portion of the proceeds from the sale
were used to fund the acquisition of two development properties totaling $622.2
million. The timing of any potential future disposition or strategic venture
transactions will depend on market conditions and other factors, including but
not limited to our capital needs, the availability of financing for potential
buyers (which has been and may continue to be constrained for some potential
buyers due to the ongoing COVID-19 pandemic's impact on economic and market
conditions, including the financial markets), and our ability to defer some or
all of the taxable gains on the sales. We cannot assure that we will dispose of
any additional properties, enter into any additional strategic ventures, or that
we will be able to identify and complete the acquisition of a suitable
replacement property to effect a Section 1031 Exchange or be able to use other
tax deferred structures in connection with our strategy. See the "Liquidity and
Capital Resources of the Operating Partnership - Liquidity Sources" section for
further information.

Acquisitions. During the six months ended June 30, 2021, we acquired two
development properties in two transactions for a total cash purchase price of
$622.2 million. As part of our growth strategy, which is highly dependent on
market conditions and business cycles, among other factors, we continue to
evaluate strategic opportunities and remain a disciplined buyer of development
and redevelopment opportunities as well as value-add and strategic operating
properties.  We focus on growth opportunities primarily in markets populated by
knowledge and creative-based tenants in a variety of industries, including
technology, media, healthcare, life sciences, entertainment and professional
services.  Against the backdrop of market volatility, we expect to manage a
strong balance sheet, execute on our development program and selectively
evaluate opportunities that we believe have the potential to either add
immediate Net Operating Income to our portfolio or play a strategic role in our
future growth.

In connection with our growth strategy, we often have one or more potential
acquisitions of properties and/or undeveloped land under consideration that are
in varying stages of negotiation and due diligence review, or under contract, at
any point in time. However, we cannot provide assurance that we will enter into
any agreements to acquire properties or undeveloped land, or that the potential
acquisitions contemplated by any agreements we may enter into the future will be
completed. In addition, acquisitions are subject to various risks and
uncertainties and we may be unable to complete an acquisition after making a
nonrefundable deposit or incurring acquisition-related costs.

Incentive Compensation. Our Executive Compensation Committee determines
compensation, including cash bonuses and equity incentives, for our executive
officers, as defined in Rule 16 under the Exchange Act. For 2021, the annual
cash bonus program was structured to allow the Executive Compensation Committee
to evaluate a variety of key quantitative and qualitative metrics at the end of
the year and make a determination based on the Company's and management's
overall performance. Our Executive Compensation Committee also grants equity
incentive awards from time to time that include performance-based and/or
market-measure based vesting requirements and time-based vesting requirements.
As a result, accrued incentive compensation and compensation expense for future
awards may be affected by our operating and development performance, financial
results, stock price, performance against applicable performance-based vesting
goals, market conditions, liquidity measures, forfeitures and other factors.
Consequently, we cannot predict the amounts that will be recorded in future
periods related to such incentive compensation.

As of June 30, 2021, there was approximately $41.8 million of total unrecognized
compensation cost related to outstanding nonvested RSUs issued under share-based
compensation arrangements. Those costs are expected to be recognized over a
weighted-average period of 1.5 years. The ultimate amount of compensation cost
recognized related to outstanding nonvested RSUs issued under share-based
compensation arrangements may vary for performance-based RSUs that are still in
the performance period based on performance against applicable performance-based
vesting goals. The $41.8 million of unrecognized compensation cost does not
reflect the future compensation cost for any potential share-based awards that
may be issued subsequent to June 30, 2021. For additional information regarding
our equity incentive awards, see Note 9 "Share-Based Compensation" to our
consolidated financial statements included in this report.

Information on Leases Commenced and Executed



Leasing Activity and Changes in Rental Rates. The amount of net rental income
generated by our properties depends principally on our ability to maintain the
occupancy rates of currently leased space and to lease currently available
space, newly developed or redeveloped properties, newly acquired properties with
vacant space, and space available from unscheduled lease terminations. The
amount of rental income we generate also depends on our ability to maintain or
increase rental rates in our submarkets. Negative trends in one or more of these
factors could adversely affect our rental income in future periods. The
following tables set forth certain information regarding leasing activity for
our stabilized portfolio during the three and six months ended June 30, 2021.

(1)Includes 100% of consolidated property partnerships.
(2)First generation leasing includes space where we have made capital
expenditures that result in additional revenue generated when the space is
re-leased. Second generation leasing includes space where we have made capital
expenditures to maintain the current market revenue stream.
(3)Represents leasing activity for leases that commenced or were signed during
the period, including first and second generation space, net of month-to-month
leases. Excludes leasing on new construction.
(4)Calculated as the percentage of space either renewed or expanded into by
existing tenants or subtenants at lease expiration.
(5)Tenant improvements and leasing commissions per square foot exclude
tenant-funded tenant improvements.
(6)Calculated as the change between GAAP rents for new/renewed leases and the
expiring GAAP rents for the same space. Excludes leases for which the space was
vacant longer than one year or vacant when the property was acquired.
(7)Excludes commenced and executed leases of approximately 55,098 and 16,136
rentable square feet, respectively, for the three months ended June 30, 2021 and
commenced and executed leases of approximately 222,835 and 61,638 rentable
square feet, respectively, for the six months ended June 30, 2021, for which the
space was vacant longer than one year or being leased for the first time. Space
vacant for more than one year is excluded from our change in rents calculations
to provide a more meaningful market comparison.
(8)Calculated as the change between stated rents for new/renewed leases and the
expiring stated rents for the same space. Excludes leases for which the space
was vacant longer than one year or vacant when the property was acquired.
(9)During the three months ended June 30, 2021, 10 new leases totaling 137,438
rentable square feet were signed but not commenced as of June 30, 2021. During
the six months ended June 30, 2021, 12 new leases totaling 149,577 rentable
square feet were signed but not commenced as of June 30, 2021.

Our rental rates and occupancy are impacted by general economic conditions,
including the pace of regional economic growth and access to capital. Therefore,
we cannot give any assurance that leases will be renewed or that available space
will be re-leased at rental rates equal to or above the current market rates. In
addition, due to the low level of recent transaction volume as a result of the
COVID-19 pandemic, we are currently unable to provide meaningful information on
the weighted average cash rental rates for our total stabilized portfolio
compared to current market rates at June 30, 2021. As restrictions intended to
prevent the spread of COVID-19 began to be lifted during the six months ended
June 30, 2021, we saw an increase in prospective tenant tours and inquiries.
While we do not believe that our development leasing and ability to renew leases
scheduled to expire has been significantly impacted by the COVID-19 pandemic, we
do believe that the impact of the restrictions and social distancing guidelines
and the economic uncertainty caused by the COVID-19 pandemic has impacted the
timing and volume of leasing and may continue to do so in the future,
particularly if case rates surge again. Additionally, decreased demand,
increased competition (including sublease space available from our tenants) and
other negative trends or unforeseeable events that impair our ability to timely
renew or re-lease space could have further negative effects on our future
financial condition, results of operations, and cash flows.

(1)For leases that have been renewed early with existing tenants, the expiration
date and annualized base rent information presented takes into consideration the
renewed lease terms. Excludes leases not commenced as of June 30, 2021, space
leased under month-to-month leases, storage leases, vacant space and future
lease renewal options not executed as of June 30, 2021.
(2)Annualized base rent includes the impact of straight-lining rent escalations
and the amortization of free rent periods and excludes the impact of the
following: amortization of deferred revenue related tenant-funded tenant
improvements, amortization of above/below market rents, amortization for lease
incentives due under existing leases and expense reimbursement revenue.
Additionally, the underlying leases contain various expense structures including
full service gross, modified gross and triple net. Percentages represent
percentage of total portfolio annualized contractual base rental revenue. For
additional information on tenant improvement and leasing commission costs
incurred by the Company for the current reporting period, please see further
discussion under the caption "Information on Leases Commenced and Executed."
(3)Includes 100% of annualized base rent of consolidated property partnerships.
(4)Adjusting for leases executed as of June 30, 2021 but not yet commenced, the
2021 and 2022 expirations would be reduced by 78,759 and 50,343 square feet,
respectively.

In addition to the 1.2 million rentable square feet, or 8.2%, of currently
available space in our stabilized portfolio, leases representing approximately
2.6% and 6.0% of the occupied square footage of our stabilized portfolio are
scheduled to expire during the remainder of 2021 and in 2022, respectively. The
leases scheduled to expire during the remainder of 2021 and in 2022 represent
approximately 1.1 million rentable square feet or 6.9% of our total annualized
base rental revenue. Adjusting for leases executed as of June 30, 2021 but not
yet commenced, the remaining 2021 and 2022 expirations would be 254,545 and
718,471 square feet, respectively.
Sublease Space. Of our leased space as of June 30, 2021, approximately 1,459,413
rentable square feet, or 10.3% of the square footage in our stabilized
portfolio, was available for sublease, primarily in the San Francisco Bay Area
region. Of the 10.3% of available sublease space in our stabilized portfolio as
of June 30, 2021, approximately 7.4% was vacant space, and the remaining 2.9%
was occupied. Of the approximately 1,459,413 rentable square feet available for
sublease as of June 30, 2021, approximately 12,146 rentable square feet
representing 4 leases are scheduled to expire in 2021, and approximately 50,465
rentable square feet representing 8 leases are scheduled to expire in 2022.

Stabilized Portfolio Information



As of June 30, 2021, our stabilized portfolio was comprised of 118 office
properties encompassing an aggregate of approximately 14.2 million rentable
square feet and 1,001 residential units. Our stabilized portfolio includes all
of our properties with the exception of development and redevelopment properties
currently committed for construction, under construction, or in the tenant
improvement phase, undeveloped land and real estate assets held for sale. We
define redevelopment properties as those properties for which we expect to spend
significant development and construction costs on the existing or acquired
buildings pursuant to a formal plan, the intended result of which is a higher
economic return on the property. We define properties in the tenant improvement
phase as office and life science properties that we are developing or
redeveloping where the project has reached cold shell condition and is ready for
tenant improvements, which may require additional major base building
construction before being placed in service. Projects in the tenant improvement
phase are added to our stabilized portfolio once the project reaches the earlier
of 95% occupancy or one year from the date of the cessation of major base
building construction activities. Costs capitalized to construction in progress
for development and redevelopment properties are transferred to land and
improvements, buildings and improvements, and deferred leasing costs on our
consolidated balance sheets as the historical cost of the property as the
projects or phases of projects are placed in service.

We did not have any redevelopment or held for sale properties at June 30, 2021.
Our stabilized portfolio also excludes our future development pipeline, which as
of June 30, 2021 was comprised of six potential development sites, representing
approximately 59 gross acres of undeveloped land on which we believe we have the
potential to develop more than 5.5 million rentable square feet, depending upon
economic conditions.

As of June 30, 2021, the following properties were excluded from our stabilized
portfolio:
                                                                   Number of                    Estimated Rentable

Results of Operations

Net Operating Income



Management internally evaluates the operating performance and financial results
of our stabilized portfolio based on Net Operating Income. We define
"Net Operating Income" as consolidated operating revenues (rental income and
other property income) less consolidated operating expenses (property expenses,
real estate taxes and ground leases).

Net Operating Income is considered by management to be an important and
appropriate supplemental performance measure to net income because we believe it
helps both investors and management to understand the core operations of our
properties excluding corporate and financing-related costs and non-cash
depreciation and amortization. Net Operating Income is an unlevered operating
performance metric of our properties and allows for a useful comparison of the
operating performance of individual assets or groups of assets. This measure
thereby provides an operating perspective not immediately apparent from GAAP
income from operations or net income. In addition, Net Operating Income is
considered by many in the real estate industry to be a useful starting point for
determining the value of a real estate asset or group of assets. Other real
estate companies may use different methodologies for calculating Net Operating
Income, and accordingly, our presentation of Net Operating Income may not be
comparable to other real estate companies. Because of the exclusion of the items
shown in the reconciliation below, Net Operating Income should only be used as a
supplemental measure of our financial performance and not as an alternative to
GAAP income from operations or net income.

Management further evaluates Net Operating Income by evaluating the performance from the following property groups:



•Same Store Properties - includes the consolidated results of all of the office
properties that were owned and included in our stabilized portfolio for two
comparable reporting periods, i.e., owned and included in our stabilized
portfolio as of January 1, 2020 and still owned and included in the stabilized
portfolio as of June 30, 2021, including our 200-unit residential tower in
Hollywood, California;

•Development Properties - includes the results generated by certain of our
in-process development projects, expenses for certain of our future development
project and the results generated by the following stabilized development
properties:

•One retail development project that was added to the stabilized portfolio in
the first quarter of 2020;
•One office development project that was added to the stabilized portfolio in
the fourth quarter of 2020;
•One office development project that was added to the stabilized portfolio in
the first quarter of 2021
•One office building that was added to the stabilized portfolio in the second
quarter of 2021;
•608 residential units at our One Paseo mixed-use project in Del Mar, California
that were added to the stabilized portfolio in the third quarter of 2020; and
•193 residential units at our Jardine project in Hollywood, California that were
added to the stabilized portfolio in the second quarter of 2021; and

•Disposition Properties- includes the results of one property disposed of in the fourth quarter of 2020 and one property disposed of in the first quarter of 2021.

The following table sets forth certain information regarding the property groups within our stabilized office portfolio as of June 30, 2021:

•An increase in total operating revenues of $10.2 million primarily due to:

•$6.2 million increase due to lower charges against rental income in 2021 related to tenant creditworthiness considerations primarily as a result of COVID-19, predominantly for retail tenants, of which $1.5 million was related to payments of past due amounts from tenants on a cash basis of revenue recognition;



•A net $1.9 million increase resulting from a $2.7 million increase from new
leases and renewals at higher rates primarily in the San Francisco Bay Area and
San Diego County regions, offset by a $0.8 million decrease due to lower

•$1.4 million increase in property expenses including repairs and maintenance,
engineering, utilities, security, parking, and various other recurring expenses
as tenants begin returning to the office;

across the portfolio; partially offset by a property tax exemption related to
one tenant;

severance costs in 2020 related to the departure of an executive officer and
certain other employees; and

ended June 30, 2020 primarily due to a decrease in the average development asset
balances qualifying for interest capitalization during the three months ended
June 30, 2021. During the three months ended June 30, 2021 and 2020, we
capitalized interest on in-process development projects and future development
pipeline projects with an average aggregate cost basis of approximately $1.8
billion and $2.1 billion, respectively, as it was determined these projects
qualified for interest and other carrying cost capitalization under GAAP. In the
event of an extended cessation of development activities to get any of these
projects ready for its intended use, such projects could potentially no longer
qualify for capitalization of interest or other carrying costs. However, a
cessation of development activities caused by events outside of our control,
such as those as a result of government restrictions aimed at stopping the
spread of COVID-19, would not impact our ability to capitalize interest and
other carrying costs.

Net Income Attributable to Noncontrolling Interests in Consolidated Property Partnerships



Net income attributable to noncontrolling interests in consolidated property
partnerships increased $2.3 million or 53.1% or the three months ended June 30,
2021 compared to the three months ended June 30, 2020 primarily due to new
leases at higher rates at two properties held in two property partnerships. The
amounts reported for the three months ended June 30, 2021 and 2020 are comprised
of the noncontrolling interest's share of net income for 100 First Street
Member, LLC ("100 First LLC") and 303 Second Street Member, LLC ("303 Second
LLC") and the noncontrolling interest's share of net income for Redwood City
Partners, LLC ("Redwood LLC").

Net Operating Income increased $15.8 million, or 5.0%, for the six months ended June 30, 2021 as compared to the six months ended June 30, 2020 primarily resulting from:

•An increase of $5.5 million attributable to the Same Store Properties primarily resulting from:

•An increase in total operating revenues of $5.2 million primarily due to:



•$7.9 million increase primarily due to lower charges against rental income
related to tenant creditworthiness considerations primarily as a result of the
COVID-19 pandemic;

•$0.8 million increase in the tenant reimbursements component of rental income
due to higher operating expenses, higher occupancy, and base year adjustments
for certain properties, partially offset by a property tax exemption for one
tenant and abatements related to one tenant; and

•$0.4 million increase due to early lease termination fees received in 2021 primarily related to one tenant; partially offset by



•$3.6 million decrease due to lower parking income, of which $2.4 million
relates to a reduction in the number of monthly parking spaces rented as a
result of COVID-19 stay-at-home orders and $1.2 million relates to lower
transient and special event parking income at a number of properties in the San
Francisco Bay Area, Greater Seattle and Greater Los Angeles regions. We expect
daily, special event and transient parking to be impacted while restrictions
intended to prevent the spread of COVID-19 remain in effect; and

•$0.2 million decrease primarily due to lower occupancy in the Greater Los Angeles region;

•$0.4 million decrease in property expenses primarily due to a decrease in reimbursable expenses such as utilities, parking, and janitorial, partially offset by an increase in various non-recurring expenses; and

•$0.8 million decrease in ground rent due to reductions in property taxes related to two ground lease land parcels and lower percentage rent; partially offset by



•$1.0 million increase in real estate taxes due to an increase in annual taxes
across the portfolio, refunds received in 2020 related to a reduced assessed
value for one property, partially offset by a property tax exemption related to
one property;


•An increase of $27.2 million attributable to the Development Properties; partially offset by

•A decrease of $16.9 million attributable to the Disposition Properties.

Other Expenses and Income

General and Administrative Expenses



General and administrative expenses decreased $11.1 million, or 19.3%, for the
six months ended June 30, 2021 compared to the six months ended June 30, 2020
primarily due to the following:

•A decrease of $12.6 million in compensation related expenses, primarily due to
severance costs related to the departure of an executive officer and certain
other employees in 2020; partially offset by

•An increase of $1.5 million related to the mark-to-market adjustment for the
Company's deferred compensation plan, which is offset by gains on the underlying
marketable securities included in interest income and other net investment gains
in the consolidated statements of operations.

Leasing Costs



Leasing costs decreased by $1.2 million or 43.5%, for the six months ended
June 30, 2021 compared to the six months ended June 30, 2020 primarily due to
changes in personnel and a lower level of leasing activity during the six months
ended June 30, 2021.

Depreciation and Amortization

Depreciation and amortization decreased $4.9 million, or 3.2%, for the six months ended June 30, 2021 compared to the six months ended June 30, 2020 primarily due to the following:

•A decrease of $9.8 million attributable to the Same Store Properties; and

•A decrease of $7.7 million attributable to the Disposition Properties; partially offset by

•An increase of $12.6 million attributable to the Development Properties.

June 30, 2021 as compared to the six months ended June 30, 2020 primarily due to
an increase in our average debt balance for the six months ended June 30, 2021.


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

Capitalized interest and deferred financing costs decreased $7.0 million or
16.6%, for the six months ended June 30, 2021 compared to the six months ended
June 30, 2020 primarily due to a decrease in the average development asset
balances qualifying for interest capitalization for the six months ended
June 30, 2021. During the six months ended June 30, 2021 and 2020, we
capitalized interest on in-process development projects and future development
pipeline projects with an average aggregate cost basis of approximately $1.8
billion and $2.2 billion, respectively.

Net Income Attributable to Noncontrolling Interests in Consolidated Property Partnerships



Net income attributable to noncontrolling interests in consolidated property
partnerships increased $2.3 million or 25.0% for the six months ended June 30,
2021 compared to the six months ended June 30, 2020 primarily due to new leases
at higher rates at two properties held in two property partnerships. The amounts
reported for the six months ended June 30, 2021 and 2020 are comprised of the
noncontrolling interest's share of net income for 100 First Street Member, LLC
("100 First LLC"), 303 Second Street Member ("303 Second LLC") and Redwood City
Partners, LLC ("Redwood LLC").

Liquidity and Capital Resources of the Company



In this "Liquidity and Capital Resources of the Company" section, the term the
"Company" refers only to Kilroy Realty Corporation on an unconsolidated basis
and excludes the Operating Partnership and all other subsidiaries.

The Company's business is operated primarily through the Operating Partnership.
Distributions from the Operating Partnership are the Company's primary source of
capital. The Company believes the Operating Partnership's sources of working
capital, specifically its cash flow from operations and borrowings available
under its unsecured revolving credit facility and funds from its capital
recycling program, including strategic ventures, are adequate for it to make its
distribution payments to the Company and, in turn, for the Company to make its
dividend payments to its common stockholders for the next twelve months. Cash
flows from operating activities generated by the Operating Partnership for the
six months ended June 30, 2021 were sufficient to cover the Company's payment of
cash dividends to its stockholders. However, there can be no assurance that the
Operating Partnership's sources of capital will continue to be available at all
or in amounts sufficient to meet its needs, including its ability to make
distributions to the Company. The unavailability of capital could adversely
affect the Operating Partnership's ability to make distributions to the Company,
which would in turn, adversely affect the Company's ability to pay cash
dividends to its stockholders.

The Company is a well-known seasoned issuer and the Company and the Operating
Partnership have an effective shelf registration statement that provides for the
public offering and sale from time to time by the Company of its preferred
stock, common stock, depositary shares, warrants and guarantees of debt
securities and by the Operating Partnership of its debt securities, in each case
in unlimited amounts. The Company evaluates the capital markets on an ongoing
basis for opportunities to raise capital, and, as circumstances warrant, the
Company and the Operating Partnership may issue securities of all of these types
in one or more offerings at any time and from time to time on an opportunistic
basis, depending upon, among other things, market conditions, available pricing
and capital needs. When the Company receives proceeds from the sales of its
preferred or common stock, it generally contributes the net proceeds from those
sales to the Operating Partnership in exchange for corresponding preferred or
common partnership units of the Operating Partnership. The Operating Partnership
may use these proceeds and proceeds from the sale of its debt securities to
repay debt, including borrowings under its unsecured revolving credit facility,
to develop new or existing properties, to make acquisitions of properties or
portfolios of properties, or for general corporate purposes.

As the sole general partner with control of the Operating Partnership, the
Company consolidates the Operating Partnership for financial reporting purposes,
and the Company does not have significant assets other than its investment in
the Operating Partnership. Therefore, the assets and liabilities and the
revenues and expenses of the Company and the Operating Partnership are
substantially the same on their respective financial statements. The section
entitled "Liquidity and Capital Resources of the Operating Partnership" should
be read in conjunction with this section to understand the liquidity and capital
resources of the Company on a consolidated basis and how the Company is operated
as a whole.

Liquidity Highlights

As of June 30, 2021, we had approximately $519.3 million in cash and cash
equivalents and approximately $450.5 million of restricted cash, of which $431.5
million is remaining from the operating property disposition completed during
the six months ended June 30, 2021 and may be released from the qualified
intermediary at our direction, should we choose not to complete a Section 1031
Exchange. As of the date of this report, we had $1.1 billion available under our
unsecured revolving credit facility and our next material debt maturity occurs
in January 2023. We believe that our available liquidity demonstrates a strong
balance sheet and makes us well positioned to navigate any additional future
uncertainties. In addition, the Company is a well-known seasoned issuer and has
historically been able to raise capital on a timely basis in the public markets,
as well as the private markets. Any future financings, however, will depend on
market conditions for both capital raises and the investment of such proceeds,
and there can be no assurances that we will successfully obtain such financings.


                                       46
--------------------------------------------------------------------------------

Distribution Requirements



The Company is required to distribute 90% of its taxable income (subject to
certain adjustments and excluding net capital gains) on an annual basis to
maintain qualification as a REIT for federal income tax purposes and is required
to pay income tax at regular corporate rates to the extent it distributes less
than 100% of its taxable income (including capital gains). As a result of these
distribution requirements, the Operating Partnership cannot rely on retained
earnings to fund its on-going operations to the same extent as other companies
whose parent companies are not REITs. In addition, the Company may be required
to use borrowings under the Operating Partnership's revolving credit facility,
if necessary, to meet REIT distribution requirements and maintain its REIT
status. The Company may also need to continue to raise capital in the equity
markets to fund the Operating Partnership's working capital needs, as well as
potential developments of new or existing properties or acquisitions.

The Company intends to continue to make, but has not committed to make, regular
quarterly cash distributions to common stockholders, and through the Operating
Partnership, to common unitholders from the Operating Partnership's cash flow
from operating activities. All such distributions are at the discretion of the
Board of Directors. As the Company intends to maintain distributions at a level
sufficient to meet the REIT distribution requirements and minimize its
obligation to pay income and excise taxes, it will continue to evaluate whether
the current levels of distribution are appropriate to do so throughout 2021. In
addition, in the event the Company is unable to identify and complete the
acquisition of suitable replacement properties to effect Section 1031 Exchanges
to defer some or all of the taxable gains related to the disposition completed
during the six months ended June 30, 2021 for gross proceeds of $1.08 billion or
any future dispositions (or in the event additional legislation is enacted that
further modifies or repeals laws with respect to Section 1031 Exchanges), the
Company may be required to distribute a special dividend to its common
stockholders and common unitholders in order to minimize or eliminate income
taxes on such gains. The Company considers market factors and its performance in
addition to REIT requirements in determining its distribution levels. Amounts
accumulated for distribution to stockholders are invested primarily in
interest-bearing accounts and short-term interest-bearing securities, which is
consistent with the Company's intention to maintain its qualification as a REIT.
Such investments may include, for example, obligations of the Government
National Mortgage Association, other governmental agency securities,
certificates of deposit, and interest-bearing bank deposits.

On May 20, 2021, the Board of Directors declared a regular quarterly cash
dividend of $0.50 per share of common stock. The regular quarterly cash dividend
is payable to stockholders of record on June 30, 2021 and a corresponding cash
distribution of $0.50 per Operating Partnership unit is payable to holders of
the Operating Partnership's common limited partnership interests of record on
June 30, 2021, including those owned by the Company. The total cash quarterly
dividends and distributions paid on July 14, 2021 were $58.8 million.

Debt Covenants



The covenants contained within certain of our unsecured debt obligations
generally prohibit the Company from paying dividends during an event of default
in excess of an amount which results in distributions to us in an amount
sufficient to permit us to pay dividends to our stockholders that we reasonably
believe are necessary to (a) maintain our qualification as a REIT for federal
and state income tax purposes and (b) avoid the payment of federal or state
income or excise tax.

Capitalization



As of June 30, 2021, our total debt as a percentage of total market
capitalization was 32.5%, which was calculated based on the closing price per
share of the Company's common stock of $69.64 on June 30, 2021 as shown in the
following table:

Liquidity and Capital Resources of the Operating Partnership

In this "Liquidity and Capital Resources of the Operating Partnership" section, the terms "we," "our," and "us" refer to the Operating Partnership or the Operating Partnership and the Company together, as the context requires.

General

Our primary liquidity sources and uses are as follows:

Liquidity Sources



•Net cash flow from operations;
•Borrowings under the Operating Partnership's unsecured revolving credit
facility;
•Proceeds from our capital recycling program, including the disposition of
assets and the formation of strategic ventures;
•Proceeds from additional secured or unsecured debt financings; and
•Proceeds from public or private issuance of debt, equity or preferred equity
securities.

Liquidity Uses

•Development and redevelopment costs;
•Operating property or undeveloped land acquisitions;
•Property operating and corporate expenses;
•Capital expenditures, tenant improvement and leasing costs;
•Debt service and principal payments, including debt maturities;
•Distributions to common security holders;
•Repurchases and redemptions of outstanding common stock of the Company; and
•Outstanding debt repurchases, redemptions and repayments.

General Strategy



Our general strategy is to maintain a conservative balance sheet with a strong
credit profile and to maintain a capital structure that allows for financial
flexibility and diversification of capital resources. We manage our capital
structure to reflect a long-term investment approach and utilize multiple
sources of capital to meet our long-term capital requirements. We believe that
our current projected liquidity requirements for the next twelve-month period,
as set forth above under the caption "-Liquidity Uses," will be satisfied using
a combination of the liquidity sources listed above, although there can be no
assurance in this regard. We believe our conservative leverage and staggered
debt maturities provide us with financial flexibility and enhance our ability to
obtain additional sources of liquidity if necessary, and, therefore, we are
well-positioned to refinance or repay maturing debt and to pursue our strategy
of seeking attractive acquisition opportunities, which we may finance, as
necessary, with future public and private issuances of debt and equity
securities, although there can be no assurance in this regard.

Liquidity Sources

Unsecured Revolving Credit Facility



In April 2021, the Operating Partnership amended and restated the terms of its
unsecured revolving credit facility. The amendment and restatement increased the
size of the unsecured revolving credit facility from $750.0 million to
$1.1 billion, reduced the borrowing costs, extended the maturity date of the
unsecured revolving credit facility to July 2025, with two six-month extension
options, and added a sustainability-linked pricing component whereby the
interest rate is lowered by 0.01% if certain sustainability performance targets
are met. The LIBOR replacement provisions of the unsecured revolving credit
facility permit the use of rates based on the secured overnight financing rate
("SOFR") administered by the Federal Reserve Bank of New York.

The following table summarizes the balance and terms of our unsecured revolving credit facility as of June 30, 2021 and December 31, 2020:


                                June 30, 2021      December 31, 2020

Interest rate (2)                      1.00  %                1.14  %

Maturity date                     July 2025            July 2022


________________________
(1)We may elect to borrow, subject to bank approval and obtaining commitments
for any additional borrowing capacity, up to an additional $500.0 million and
$600.0 million as of June 30, 2021 and December 31, 2020, respectively, under an
accordion feature under the terms of the unsecured revolving credit facility.
(2)Our unsecured revolving credit facility interest rate was calculated based on
the contractual rate of LIBOR plus 0.900% and LIBOR plus 1.000% as of June 30,
2021 and December 31, 2020, respectively.
(3)Our facility fee is paid on a quarterly basis and is calculated based on the
total borrowing capacity. In addition to the facility fee, we incurred debt
origination and legal costs. As of June 30, 2021 and December 31, 2020, $8.3
million and $2.1 million of unamortized deferred financing costs, respectively,
which are included in prepaid expenses and other assets, net on our consolidated
balance sheets, remained to be amortized through the respective maturity dates
presented of our unsecured revolving credit facility.

We intend to borrow under the unsecured revolving credit facility as necessary
for general corporate purposes, to finance development and redevelopment
expenditures, to fund potential acquisitions and to potentially repay long-term
debt to supplement cash balances given uncertainties and volatility in market
conditions.

Capital Recycling Program

As discussed in the section "Factors That May Influence Future Results of
Operations - Capital Recycling Program," we continuously evaluate opportunities
for the potential disposition of properties and undeveloped land in our
portfolio or the formation of strategic ventures with the intent of recycling
the proceeds generated from the disposition of less strategic or core assets
into capital used to finance development expenditures, to fund new acquisitions,
to repay long-term debt and for other general corporate purposes. As part of
this strategy, we attempt to enter into Section 1031 Exchanges, when possible,
to defer some or all of the taxable gains on the sales, if any, for federal and
state income tax purposes.

In connection with our capital recycling strategy, during the six months ended
June 30, 2021, we completed the sale of one operating property in San Francisco,
California to an unaffiliated third party for gross proceeds of $1.08 billion,
or approximately $1,440 per square foot. During the three months ended June 30,
2021, a portion of the proceeds from the sale were used to fund two development
acquisitions totaling $622.2 million and as of June 30, 2021, $431.5 million of
the proceeds from the sale are still temporarily being held by a qualified
intermediary, at our direction, for the purpose of facilitating a Section 1031
Exchange. Any potential future disposition transactions and the timing of any
potential future capital recycling transactions will depend on market conditions
and other factors, including but not limited to our capital needs, the
availability of financing for potential buyers (which has been and may continue
to be constrained for some potential buyers due to the ongoing COVID-19
pandemic's impact on economic and market conditions, including the financial
markets), and our ability to defer some or all of the taxable gains on the
sales. In addition, we cannot assure you that we will dispose of any additional
properties, or that we will be able to identify and complete the acquisitions of
suitable replacement properties to effect Section 1031 Exchanges to defer some
or all of the taxable gains related to our capital recycling program. In the
event we are unable to complete dispositions as planned, we may raise capital
through other sources of liquidity including our available unsecured revolving
credit facility or the public or private issuance of unsecured debt.

At-The-Market Stock Offering Program



Under our current at-the-market stock offering program, which commenced June
2018, we may offer and sell shares of our common stock with an aggregate gross
sales price of up to $500.0 million from time to time in "at-the-market"
offerings. In connection with the at-the-market program, the Company may enter
into forward equity sale agreements with certain financial institutions acting
as forward purchasers whereby, at our discretion, the forward purchasers may
borrow and sell shares of our common stock under our at-the-market program. The
use of a forward equity sale agreement allows the Company to lock in a share
price on the sale of shares of our common stock at the time the agreement is
executed but defer settling the forward equity sale agreements and receiving the
proceeds from the sale of shares until a later date. The Company did not have
any outstanding forward equity sale agreements to be settled at June 30, 2021.

Since commencement of our current at-the-market program, we have completed sales
of 3,594,576 shares of common stock through June 30, 2021. As of June 30, 2021,
we may offer and sell shares of our common stock having an aggregate gross sales
price up to approximately $214.2 million under our current at-the-market
program. The Company did not complete any sales of common stock under the
program during the six months ended June 30, 2021.

Shelf Registration Statement



The Company is a well-known seasoned issuer and the Company and the Operating
Partnership have an effective shelf registration statement that provides for the
public offering and sale from time to time by the Company of its preferred
stock, common stock, depository shares and guarantees of debt securities and by
the Operating Partnership of its debt securities, in each case in unlimited
amounts. The Company evaluates the capital markets on an ongoing basis for
opportunities to raise capital, and, as circumstances warrant, the Company and
the Operating Partnership may issue securities of all of these types in one or
more offerings at any time and from time to time on an opportunistic basis,
depending upon, among other things, market conditions, available pricing and
capital needs. Capital raising could be more challenging under current market
conditions than those prior to COVID-19, particularly if case rates surge again.
When the Company receives proceeds from the sales of its preferred or common
stock, it generally contributes the net proceeds from those sales to the
Operating Partnership in exchange for corresponding preferred or common
partnership units of the Operating Partnership. The Operating Partnership may
use these proceeds and proceeds from the sale of its debt securities to repay
debt, including borrowings under its unsecured revolving credit facility, to
develop new or existing properties, to make acquisitions of properties or
portfolios of properties, or for general corporate purposes.

Unsecured and Secured Debt

The aggregate principal amount of the unsecured and secured debt of the Operating Partnership outstanding as of June 30, 2021 was as follows:

Liquidity Uses

Contractual Obligations



Refer to our 2020 Annual Report on Form 10-K for a discussion of our contractual
obligations. There have been no material changes, outside of the ordinary course
of business, to these contractual obligations during the six months ended June
30, 2021.

Other Liquidity Uses

  Development

As of June 30, 2021, we had two development projects under construction.  These
projects have a total estimated investment of approximately $1.1 billion of
which we have incurred approximately $271.0 million, net of retention, and
committed an additional $809.0 million as of June 30, 2021, of which $36.0
million is currently expected to be spent through the end of 2021. In addition,
as of June 30, 2021, we had four development projects in the tenant improvement
phase. These projects have a total estimated investment of approximately $1.8
billion, of which we have incurred approximately $1.5 billion, net of retention,
and committed an additional $305.0 million as of June 30, 2021, of which $102.0
million is currently expected to be spent through the end of 2021. We also had
four stabilized development projects with a total estimated investment of $645.0
million, of which $64.0 million remains to be spent as of June 30, 2021, and is
expected to be spent through the end of 2021. Furthermore, we currently believe
we may spend up to $25.0 million on committed and future development pipeline
projects that we may commence construction on throughout the remainder of 2021.
The ultimate timing of these expenditures may fluctuate given construction
progress and leasing status of the projects, or as a result of events outside
our control, such as delays or increased costs as a result of the COVID-19
pandemic. We expect that any material additional development activities will be
funded with borrowings under the unsecured revolving credit facility, the public
or private issuance of debt or equity securities, the disposition of assets
under our capital recycling program, or strategic venture opportunities. We
cannot provide assurance that development projects will be completed on the
terms, for the amounts or on the timelines currently contemplated, or at all.

Debt Maturities



We believe our conservative leverage, staggered debt maturities and recent
unsecured line of credit amendment provide us with financial flexibility and
enhance our ability to obtain additional sources of liquidity if necessary, and,
therefore, we believe we are well-positioned to refinance or repay maturing debt
and to pursue our strategy of seeking attractive acquisition opportunities,
which we may finance, as necessary, with future public and private issuances of
debt and equity securities. However, we can provide no assurance that we will
have access to the public or private debt or equity markets in the future on
favorable terms or at all. Our next debt maturity occurs in January 2023.

Potential Future Acquisitions



As discussed in the section "Factors That May Influence Future Results of
Operations - Acquisitions," we continue to evaluate strategic opportunities and
remain a disciplined buyer of development and redevelopment opportunities as
well as value-add and strategic operating properties, dependent on market
conditions and business cycles, among other factors.  We focus on growth
opportunities primarily in markets populated by knowledge and creative based
tenants in a variety of industries, including technology, media, healthcare,
life sciences, entertainment and professional services.  We expect that any
material acquisitions will be funded with borrowings under the unsecured
revolving credit facility, the public or private issuance of debt or equity
securities, the disposition of assets under our capital recycling program, the
formation of strategic ventures or through the assumption of existing debt,
although there can be no assurance in this regard.

We cannot provide assurance that we will enter into any agreements to acquire
properties or undeveloped land, or that the potential acquisitions contemplated
by any agreements we may enter into in the future will be completed.

Share Repurchases



As of June 30, 2021, 4,935,826 shares remained eligible for repurchase under a
share repurchase program approved by the Company's board of directors in 2016.
Under this program, repurchases may be made in open market transactions at
prevailing prices or through privately negotiated transactions. We may elect to
repurchase shares of our common stock under this program in the future depending
upon various factors, including market conditions, the trading price of our
common stock and our other
                                       53
--------------------------------------------------------------------------------

uses of capital. This program does not have a termination date and repurchases may be discontinued at any time. We intend to fund repurchases, if any, primarily with the proceeds from property dispositions.

Other Potential Future Liquidity Uses



The amounts we incur for tenant improvements and leasing costs depend on leasing
activity in each period. Tenant improvements and leasing costs generally
fluctuate in any given period depending on factors such as the type and
condition of the property, the term of the lease, the type of the lease, the
involvement of external leasing agents, and overall market conditions. Capital
expenditures may fluctuate in any given period subject to the nature, extent and
timing of improvements required to maintain our properties. While the COVID-19
pandemic and restrictions intended to prevent its spread remain in effect, there
may be a continued lower level of leasing activity when compared to levels prior
to the COVID-19 pandemic.

Factors That May Influence Future Sources of Capital and Liquidity of the Company and the Operating Partnership



We continue to evaluate sources of financing for our business activities,
including borrowings under the unsecured revolving credit facility, issuance of
public and private equity securities, unsecured debt and fixed-rate secured
mortgage financing, proceeds from the disposition of selective assets through
our capital recycling program, and the formation of strategic ventures. However,
our ability to obtain new financing or refinance existing borrowings on
favorable terms could be impacted by various factors, including the state of the
macro economy, the state of the credit and equity markets, significant tenant
defaults, a decline in the demand for office properties, a decrease in market
rental rates or market values of real estate assets in our submarkets, the
amount of our future borrowings and the impact of the COVID-19 pandemic, on
capital and credit markets and our tenants (refer to "Part I, Item IA. Risk
Factors" in our annual report on Form 10-K for the year ended December 31, 2020
for additional information). These events could result in the following:

•Decreases in our cash flows from operations, which could create further dependence on the unsecured revolving credit facility;

•An increase in the proportion of variable-rate debt, which could increase our sensitivity to interest rate fluctuations in the future; and

•A decrease in the value of our properties, which could have an adverse effect on the Operating Partnership's ability to incur additional debt, refinance existing debt at competitive rates, or comply with its existing debt obligations.



In addition to the factors noted above, the Operating Partnership's credit
ratings are subject to ongoing evaluation by credit rating agencies and may be
changed or withdrawn by a rating agency in the future if, in its judgment,
circumstances warrant. In the event that the Operating Partnership's credit
ratings are downgraded, we may incur higher borrowing costs and may experience
difficulty in obtaining additional financing or refinancing existing
indebtedness.

Debt Covenants



The unsecured revolving credit facility, unsecured senior notes, and certain
other secured debt arrangements contain covenants and restrictions requiring us
to meet certain financial ratios and reporting requirements. Key existing
financial covenants and their covenant levels include:
Unsecured Credit Facility and Private
Placement Notes (as defined in the applicable                                                      Actual Performance
Credit Agreements):                                           Covenant Level                      as of June 30, 2021
Total debt to total asset value                               less than 60%                               28%
Fixed charge coverage ratio                                 greater than 1.5x                             3.0x
Unsecured debt ratio                                        greater than 1.67x                           3.23x
Unencumbered asset pool debt service coverage               greater than 1.75x                           3.55x

Unsecured Senior Notes due 2023, 2024, 2025,
2028, 2029, 2030 and 2032
(as defined in the applicable Indentures):
Total debt to total asset value                               less than 60%                               35%
Interest coverage                                           greater than 1.5x                             7.2x
Secured debt to total asset value                             less than 40%                                2%
Unencumbered asset pool value to unsecured
debt                                                        greater than 150%                             321%



The Operating Partnership was in compliance with all of its debt covenants as of
June 30, 2021. Our current expectation is that the Operating Partnership will
continue to meet the requirements of its debt covenants in both the short and
long term.
                                       54
--------------------------------------------------------------------------------

However, in the event of an economic slowdown or continued volatility in the
credit markets, there is no certainty that the Operating Partnership will be
able to continue to satisfy all the covenant requirements.


Consolidated Historical Cash Flow Summary

based on the consolidated statements of cash flows in Item 1. "Financial
Statements" and is not meant to be an all-inclusive discussion of the changes in
our cash flow for the periods presented below. Changes in our cash flow include
changes in cash and cash equivalents and restricted cash. Our historical cash

            469,643                    125.5  %

Net cash (used in) provided by financing activities (165,134) 695,287

Operating Activities



Our cash flows from operating activities depends on numerous factors including
the occupancy level of our portfolio, the rental rates achieved on our leases,
the collectability of rent and recoveries from our tenants, the level of
operating expenses, the impact of property acquisitions, completed development
projects and related financing activities, and other general and administrative
costs. Our net cash provided by operating activities decreased by $7.6 million,
or 3.4%, for the six months ended June 30, 2021 compared to the six months ended
June 30, 2020 primarily as a result of net changes in other operating assets
related to the timing of expenditures. See additional information under the
caption "-Results of Operations."

Investing Activities



Our cash flows from investing activities is generally used to fund development
and operating property acquisitions, expenditures for development projects, and
recurring and nonrecurring capital expenditures for our operating properties,
net of proceeds received from dispositions of real estate assets. During the six
months ended June 30, 2021 we had net cash provided by investing activities of
$95.3 million compared to net cash used in investing activities of $374.3
million for the six months ended June 30, 2020 due to $1.0 billion of net
proceeds received from one operating property disposition completed during the
six months ended June 30, 2021, partially offset by $586.9 million of
expenditures for acquisitions of development properties and undeveloped land
completed during the six months ended June 30, 2021.

Financing Activities



Our cash flows from financing activities is principally impacted by our capital
raising activities, net of dividends and distributions paid to common and
preferred security holders. During the six months ended June 30, 2021 we had net
cash used in financing activities of $165.1 million compared to net cash
provided by financing activities of $695.3 million for the six months ended June
30, 2020 primarily as a result of net proceeds from the issuance of common stock
and proceeds from the issuance of unsecured debt generated during the six months
ended June 30, 2020, partially offset by net repayments on the unsecured
revolving credit facility during the six months ended June 30, 2020.

Non-GAAP Supplemental Financial Measure: Funds From Operations ("FFO")



We calculate FFO in accordance with the 2018 Restated White Paper on FFO
approved by the Board of Governors of NAREIT. The White Paper defines FFO as net
income or loss calculated in accordance with GAAP, excluding extraordinary
items, as defined by GAAP, gains and losses from sales of depreciable real
estate and impairment write-downs associated with depreciable real estate, plus
real estate-related depreciation and amortization (excluding amortization of
deferred financing costs and depreciation of non-real estate assets) and after
adjustment for unconsolidated partnerships and joint ventures. Our calculation
of FFO includes the amortization of deferred revenue related to tenant-funded
tenant improvements and excludes the depreciation of the related tenant
improvement assets. We also add back net income attributable to noncontrolling
common units of the Operating Partnership because we report FFO attributable to
common stockholders and common unitholders.

We believe that FFO is a useful supplemental measure of our operating
performance. The exclusion from FFO of gains and losses from the sale of
operating real estate assets allows investors and analysts to readily identify
the operating results of the assets that form the core of our activity and
assists in comparing those operating results between periods. Also, because FFO
is generally recognized as the industry standard for reporting the operations of
REITs, it facilitates comparisons of operating performance to other REITs.
However, other REITs may use different methodologies to calculate FFO, and
accordingly, our FFO may not be comparable to all other REITs.

Implicit in historical cost accounting for real estate assets in accordance with
GAAP is the assumption that the value of real estate assets diminishes
predictably over time. Since real estate values have historically risen or
fallen with market conditions, many industry investors and analysts have
considered presentations of operating results for real estate companies using
historical cost accounting alone to be insufficient. Because FFO excludes
depreciation and amortization of real estate assets, we believe that FFO along
with the required GAAP presentations provides a more complete measurement of our
performance relative to our competitors and a more appropriate basis on which to
make decisions involving operating, financing and investing activities than the
required GAAP presentations alone would provide.

However, FFO should not be viewed as an alternative measure of our operating
performance because it does not reflect either depreciation and amortization
costs or the level of capital expenditures and leasing costs necessary to
maintain the operating performance of our properties, which are significant
economic costs and could materially impact our results from operations.

The following table presents our FFO for the three and six months ended June 30, 2021 and 2020:
