DOCUMENTS INCORPORATED BY REFERENCE

Portions of the Kilroy Realty Corporation’s Proxy Statement with respect to its 2021 Annual Meeting of Stockholders to be filed not later than 120 days after the end of the

registrant’s fiscal year are incorporated by reference into Part III of this Form 10-K.

EXPLANATORY NOTE

This report combines the annual reports on Form 10-K for the year ended December 31, 2020 of Kilroy Realty Corporation and Kilroy Realty, L.P. Unless
stated  otherwise  or  the  context  otherwise  requires,  references  to  “Kilroy  Realty  Corporation”  or  the  “Company,”  “we,”  “our,”  and  “us”  mean  Kilroy  Realty
Corporation, a Maryland corporation, and its controlled and consolidated subsidiaries, and references to “Kilroy Realty, L.P.” or the “Operating Partnership” mean
Kilroy Realty, L.P., a Delaware limited partnership, and its controlled and consolidated subsidiaries.

The Company is a real estate investment trust, or REIT, and the general partner of the Operating Partnership. As of December 31, 2020, the Company owned
an approximate 99.0% common general partnership interest in the Operating Partnership. The remaining approximate 1.0% common limited partnership interests
are owned by non-affiliated investors and certain directors and officers of the Company. As the sole general partner of the Operating Partnership, the Company
exercises  exclusive  and  complete  discretion  over  the  Operating  Partnership’s  day-to-day  management  and  control  and  can  cause  it  to  enter  into  certain  major
transactions including acquisitions, dispositions, and refinancings and cause changes in its line of business, capital structure and distribution policies.

There  are  a  few  differences  between  the  Company  and  the  Operating  Partnership  that  are  reflected  in  the  disclosures  in  this  Form  10-K.  We  believe  it  is
important to understand the differences between the Company and the Operating Partnership in the context of how the Company and the Operating Partnership
operate as an interrelated, consolidated company. The Company is a REIT, the only material asset of which is the partnership interests it holds in the Operating
Partnership. As a result, the Company generally does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing
equity  from  time  to  time  and  guaranteeing  certain  debt  of  the  Operating  Partnership.  The  Company  itself  is  not  directly  obligated  under  any  indebtedness,  but
generally guarantees all of the debt of the Operating Partnership. The Operating Partnership owns substantially all of the assets of the Company either directly or
through its subsidiaries, conducts the operations of the Company’s business and is structured as a limited partnership with no publicly-traded equity. Except for net
proceeds  from  equity  issuances  by  the  Company,  which  the  Company  generally  contributes  to  the  Operating  Partnership  in  exchange  for  units  of  partnership
interest,  the  Operating  Partnership  generates  the  capital  required  by  the  Company’s  business  through  the  Operating  Partnership’s  operations,  by  the  Operating
Partnership’s incurrence of indebtedness or through the issuance of units of partnership interest.

Noncontrolling  interests,  stockholders’  equity  and  partners’  capital  are  the  main  areas  of  difference  between  the  consolidated  financial  statements  of  the
Company and those of the Operating Partnership. The common limited partnership interests in the Operating Partnership are accounted for as partners’ capital in
the Operating Partnership’s financial statements and, to the extent not held by the Company, as noncontrolling interests in the Company’s financial statements. The
differences between stockholders’ equity, partners’ capital and noncontrolling interests result from the differences in the equity issued by the Company and the
Operating Partnership.

We believe combining the annual reports on Form 10-K of the Company and the Operating Partnership into this single report results in the following benefits:

•

•

•

•

Combined reports better reflect how management and the analyst community view the business as a single operating unit;

Combined reports enhance investors’ understanding of the Company and the Operating Partnership by enabling them to view the business as a whole and
in the same manner as management;

Combined reports are more efficient for the Company and the Operating Partnership and result in savings in time, effort and expense; and

Combined reports are more efficient for investors by reducing duplicative disclosure and providing a single document for their review.

This document contains certain “forward-looking” statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E
of the Securities Exchange Act of 1934, as amended, including, 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  funds  from  operations,  our  ability  to  re-lease  properties  at  or  above  current  market  rates,  anticipated  market  conditions,
demographics and other forward-looking financial data, as well as the discussion in “Item 7. Management’s Discussion and Analysis of Financial Condition and
Results of Operations -Factors That May Influence Future Results of Operations.” 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. 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 securities laws.

In addition, this report contains information and statistics regarding, among other things, the industry, markets, submarkets and sectors in which we operate,
the percentage by which certain leases are above or below applicable market rents and the number of square feet of office and other space that could be developed
from specific parcels of undeveloped land. We obtained this information and these statistics from various third-party sources and our own internal estimates. We
believe that these sources and estimates are reliable but have not independently verified them and cannot guarantee their accuracy or completeness.

ITEM 1.    BUSINESS

The Company

Kilroy Realty Corporation (the “Company”) is a self-administered real estate investment trust (“REIT”) active in premier office and mixed-use submarkets
along  the  West  Coast.  We  own,  develop,  acquire  and  manage  real  estate  assets,  consisting  primarily  of  Class  A  properties  in  the  coastal  regions  of  Greater
Los Angeles, San Diego County, the San Francisco Bay Area and Greater Seattle, which we believe have strategic advantages and strong barriers to entry. Class A
real  estate  encompasses  attractive  and  efficient  buildings  of  high  quality  that  are  attractive  to  tenants,  are  well-designed  and  constructed  with  above-average
material,  workmanship  and  finishes  and  are  well-maintained  and  managed.  We  qualify  as  a  REIT  under  the  Internal  Revenue  Code  of  1986,  as  amended  (the
“Code”). We own our interests in all of our real estate assets through Kilroy Realty, L.P. (the “Operating Partnership”) and generally conduct substantially all of
our operations through the Operating Partnership.

Our stabilized portfolio of operating properties was comprised of the following properties at December 31, 2020:

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 at the historical cost of the property as the projects or phases of projects are placed in service.

During the year ended December 31, 2020, we added four development projects to our stabilized portfolio consisting of 750,370 square feet of office space in
San Francisco, California, 361,388 square feet of office space in Hollywood, California, 95,871 square feet of retail space and 608 residential units in San Diego,
California.  As  of  December  31,  2020,  the  following  properties  were  excluded  from  our  stabilized  portfolio.  We  did  not  have  any  redevelopment  properties  or
properties held for sale at December 31, 2020.

Our  stabilized  portfolio  also  excludes  our  future  development  pipeline,  which  as  of  December  31,  2020,  was  comprised  of  five  future  development  sites,

representing approximately 61 gross acres of undeveloped land.

As of December 31, 2020, all of our properties and development projects were owned and all of our business was conducted in the state of California with the
exception of eight stabilized office properties, one development project in the tenant improvement phase and one future development project located in the state of
Washington. All of our properties and development projects are 100% owned, excluding four office properties owned by three consolidated property partnerships.
Two of the three consolidated property partnerships, 100 First Street Member, LLC (“100 First LLC”) and 303 Second Street Member, LLC (“303 Second LLC”),
each owned one office property in San Francisco, California through subsidiary REITs. As of December 31, 2020, the Company owned a 56% common equity
interest in both 100 First LLC and 303 Second LLC. The third consolidated property partnership, Redwood City Partners, LLC (“Redwood LLC”), owned two
office properties in Redwood City, California. As of December 31, 2020, the Company owned an approximate 93% common equity interest in Redwood LLC. The
remaining interests in all three property partnerships were owned by unrelated third parties.

We own our interests in all of our real estate assets through the Operating Partnership and generally conduct substantially all of our operations through the
Operating  Partnership,  of  which  we  owned  a  99.0%  common  general  partnership  interest  as  of  December  31,  2020.  The  remaining  1.0%  common  limited
partnership interest in the Operating Partnership as of December 31, 2020 was owned by non-affiliated investors and certain of our executive officers and directors.
With the exception of the Operating Partnership and our consolidated property partnerships, all of our subsidiaries are wholly-owned.

Business and Growth Strategies

Growth Strategies.    We believe that a number of factors and strategies will enable us to continue to achieve our objectives of long-term sustainable growth in

Net Operating Income (defined below) and FFO (defined below) as well as maximization of long-term stockholder value. These factors and strategies include:

•

•

•

•

•

•

•

the quality, geographic location, physical characteristics and operating sustainability of our properties;

our  ability  to  efficiently  manage  our  assets  as  a  low  cost  provider  of  commercial  real  estate  through  our  seasoned  management  team  possessing  core
capabilities in all aspects of real estate ownership, including property management, leasing, marketing, financing, accounting, legal, and construction and
development management;

our  access  to  development,  redevelopment,  acquisition  and  leasing  opportunities  as  a  result  of  our  extensive  experience  and  significant  working
relationships  with  major  West  Coast  property  owners,  corporate  tenants,  municipalities  and  landowners  given  our  over  70-year  presence  in  the  West
Coast markets;

our active development program and our future development pipeline of undeveloped land sites (see “Item 7. Management’s Discussion and Analysis of
Financial Condition and Results of Operations —Factors That May Influence Future Results of Operations” for additional information pertaining to the
Company’s in-process and future development pipeline);

our capital recycling program (see “Item 7. Management’s  Discussion and Analysis of Financial Condition and Results of Operations —Liquidity and
Capital Resources of the Operating Partnership” for additional information pertaining to the Company’s capital recycling program and related property
and land dispositions);

our ability to capitalize on inflection points in a real estate cycle to add quality assets to our portfolio at substantial discounts to long-term value, through
either acquisition, development or redevelopment; and

our strong financial position that has and will continue to allow us to pursue attractive acquisition and development and redevelopment opportunities.

“Net Operating Income” subsequent to the adoption of Financial Standards Accounting Board Accounting Standards Codification Topic 842 (“Topic 842”) on
January 1, 2019 is defined as consolidated operating revenues (rental income and other property income) less consolidated operating expenses (property expenses,
real estate taxes and ground leases). Prior to the adoption of Topic 842 we defined Net Operating Income as consolidated operating revenues (rental income, tenant
reimbursements and other property income) less consolidated operating expenses (property expenses, real estate taxes, provision for bad debts and ground leases).
“FFO” is Funds From Operations available  to common stockholders  and common unitholders calculated  in accordance with the 2018 Restated White Paper on
FFO approved by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”). (See “Item 7. Management’s Discussion and
Analysis of Financial Condition and Results of Operations —Results of Operations” and “—Non-GAAP Supplemental Financial Measures: Funds From

7

Operations” for a reconciliation of these measures to generally accepted accounting principles (“GAAP”) net income available to common stockholders.)

Operating Strategies.    We focus on enhancing long-term growth in Net Operating Income and FFO from our properties by:

• maximizing cash flow from our properties through active leasing, early renewals and effective property management;

•

structuring leases to maximize returns;

• managing  portfolio  credit  risk  through  effective  underwriting,  including  the  use  of  credit  enhancements  and  interests  in  collateral  to  mitigate  portfolio

credit risk;

• managing operating expenses through the efficient use of internal property management, leasing, marketing, financing, accounting, legal, and construction

and development management functions;

• maintaining and developing long-term relationships with a diverse tenant base;

•

•

•

continuing  to effectively  manage  capital  improvements  to enhance  our properties’  competitive  advantages  in their respective  markets  and improve  the
efficiency of building systems;

continuing to expand our management team with individuals who have extensive regional and product-type experience and are highly knowledgeable in
their respective markets and product types; and

attracting and retaining motivated employees by providing financial and other incentives to meet our operating and financial goals.

Development and Redevelopment Strategies.    We and our predecessors have developed office properties primarily located in California since 1947. As of
December 31, 2020, we had three projects in the tenant improvement phase totaling approximately 1,080,000 square feet of office space and three projects under
construction totaling approximately 856,000 square feet of office and life science space and 193 residential units. In addition, our future development pipeline was
comprised of five potential development sites representing approximately 61 gross acres of undeveloped land on which we believe we have the potential to develop
over  6.0  million  square  feet  of  office,  life  science,  laboratory,  residential  and  retail  space,  depending  upon  economic  conditions.  Our  strategy  with  respect  to
development is to:

•

•

own land sites in highly populated, amenity rich locations that are attractive to a broad array of tenants;

be  the  premier  provider  of  modern  and  collaborative  office,  life  science  and  mixed-use  projects  on  the  West  Coast  with  a  focus  on  design  and
environment;

• maintain a disciplined approach by commencing development when appropriate based on market conditions, focusing on leasing, developing in stages or

phasing, and cost control;

•

•

•

reinvest capital from dispositions of selective assets into new state-of-the-art development and acquisition opportunities with higher cash flow and rates of
return or future redevelopment when possible;

execute on our development projects under construction and future development pipeline, including expanding entitlements; and

evaluate  redevelopment  opportunities  in  supply-constrained  markets  because  such  efforts  generally  achieve  similar  returns  to  new  development  with
reduced entitlement risk and shorter construction periods.

We may engage in the additional development or redevelopment of office, life science and mixed-use properties when market conditions support a favorable

risk-adjusted return on such development or redevelopment. We expect

8

that  our  significant  working  relationships  with  tenants,  municipalities  and  landowners  on  the  West  Coast  will  give  us  further  access  to  development  and
redevelopment  opportunities.  We  cannot  ensure  that  we  will  be  able  to  successfully  develop  or  redevelop  any  of  our  properties  or  that  we  will  have  access  to
additional development or redevelopment opportunities.

Acquisition Strategies.    We believe we are well positioned to acquire opportunistic properties and development and redevelopment opportunities as the result
of our extensive experience, strong financial position and ability to access capital. We continue to focus on growth opportunities in West Coast 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 add immediate Net Operating Income to our portfolio or play a strategic role in our future growth and that:

•

•

•

provide attractive yields and significant potential for growth in cash flow from property operations;

present growth opportunities in our existing or other strategic markets; and

demonstrate  the  potential  for  improved  performance  through  intensive  management,  repositioning,  capital  investment  and  leasing  that  should  result  in
increased occupancy and rental revenues.

Financing Strategies.    Our financing policies and objectives are determined by our board of directors. Our goal is to limit our dependence on leverage and
maintain  a  conservative  ratio  of  debt-to-total  market  capitalization.  As  of  December  31,  2020,  our  total  debt  as  a  percentage  of  total  market  capitalization  was
37.0%,  which  was  calculated  based  on  the  quoted  closing  price  per  share  of  the  Company’s  common  stock  of  $57.40  on  December  31,  2020  (see  “Item  7.
Management’s Discussion and Analysis of Financial Condition and Results of Operations —Liquidity and Capital Resources of the Company —Capitalization” for
additional information). Our financing strategies include:

• maintaining financial flexibility, including a low secured to unsecured debt ratio;

• maximizing our ability to access a variety of both public and private capital sources;

• maintaining  a  staggered  debt  maturity  schedule  in  which  the  maturity  dates  of  our  debt  are  spread  over  several  years  to  limit  risk  exposure  at  any

particular point in the capital and credit market cycles;

•

completing financing in advance of the need for capital;

• managing interest rate exposure by generally maintaining a greater amount of fixed-rate debt as compared to variable-rate debt; and

• maintaining our credit ratings.

We utilize multiple sources of capital, including borrowings under our unsecured revolving credit facility, proceeds from the issuance of public or private debt
or  equity  securities  and  other  bank  and/or  institutional  borrowings  and  our  capital  recycling  program,  including  strategic  venture  sources.  There  can  be  no
assurance  that  we  will  be  able  to  obtain  capital  as  needed  on  terms  favorable  to  us  or  at  all.  (See  the  discussion  under  the  caption  “Item  7.  Management’s
Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  —Factors  That  May  Influence  Future  Results  of  Operations”  and  “Item  1A.  Risk
Factors.”)

Sustainability Strategies. Our longstanding leadership in sustainability in real estate is globally recognized, and we achieved carbon neutral operations before
year-end  2020  per  the  commitment  we  made  in  2018  to  achieve  this  goal.  Our  vision  is  a  resilient  portfolio  that  minimizes  the  environmental  impact  of  the
development  and  operation  of  our  buildings  while  maximizing  the  health  and  productivity  of  our  tenants,  employees  and  communities  as  well  as  our  financial
returns. Management and our board of directors, through the Corporate Social Responsibility and Sustainability Committee (the “Committee”) established in April
2018, oversee and advance the Company’s corporate social responsibility and sustainability initiatives. They recognize that community

9

engagement and sustainable operations benefit all of our constituencies and are key to preserving our Company’s value and credibility.

As a result of our commitment to sustainability, we have been ranked first in sustainability performance in North America in the Listed Office category by the
Global Real Estate Sustainability Benchmark (“GRESB”) seven times and have also earned the highly competitive GRESB “Green Star” designation in each of the
last eight years for ranking in the top 25% of companies worldwide in sustainability performance. GRESB also named us the Global Sector Leader in Listed Office
and Listed Office Development in 2020. We have been recognized with the US EPA ENERGY STAR  Partner of the Year Sustained Excellence Award for the
last six years, NAREIT’s Leader in the Light Award in the Listed Office category for the last seven years and NAREIT’s Leader in the Light Most Innovative
award in 2018 and 2020. We have also been included on Newsweek’s list of America’s Most Responsible Companies for the past two years. For excellence in
creating a diverse, equitable and inclusive culture, we are listed on the Bloomberg Gender Equality Index, which measures companies on female leadership and
talent pipeline, equal pay and gender pay parity, inclusive culture, sexual harassment policies and pro-women brand.

We manage our properties to offer the maximum degree of utility and operational efficiency to our tenants. We offer tenant sustainability programs focused on
helping our tenants reduce their energy and water consumption and increase their recycling diversion rates. We incorporate green lease language into 100% of our
new leases, including a cost recovery clause for resource-efficiency related capital expenditures in full-service gross leases, which seek to align tenant and landlord
interests on energy, water and waste efficiency. Green leases (also known as aligned leases, high performance leases or energy efficient leases) aim to align the
financial and energy incentives of building owners and tenants so they can work together to save money, conserve resources and ensure the efficient operation of
buildings. We have won the Institute for Market Transformation’s (“IMT’s”) Green Lease Leaders award five times. Energy consumption, water consumption, and
greenhouse gas (“GHG”) emissions data for the periods indicated based on the most recent available information, in process of assurance by DNV GL Business

DNV GL Business  Assurance USA, Inc. is in the  process of completing  a Type 2, moderate  level  assurance assessment,  using the AA1000AS (2008) assurance standard to
assure  the  content  of  our  sustainability  report,  including  energy  consumption,  water  consumption  and  GHG  emissions  data.  GHG  emissions  reporting  follows  the  World
Business Council for Sustainable Development (WBSCD)/World Resources Institute (WRI) Greenhouse Gas Protocol. However, DNV GL Business Assurance USA, Inc. has
yet to complete its procedures with respect to such assessment and, as such, our final energy consumption, water consumption and GHG emissions data may differ from the data
set forth above.

(1) Full 2020 calendar year energy, water and GHG emissions data is not available until after March 30, 2021.
(2) Percentage based on gross square footage of portfolio floor area with complete energy consumption data coverage as of the end of the applicable year. Floor area is considered to
have complete energy consumption data coverage when energy consumption data (i.e., energy types and amounts consumed) is obtained by the Company for all types of energy
consumed in the relevant floor area during the fiscal year, regardless of when such data was obtained.

(3) Energy includes energy purchased from sources external to the Company and its tenants or produced by the Company or its tenants themselves (self-generated) and energy from
all  sources,  including  direct  fuel  usage,  purchased  electricity,  and  heating,  cooling  and  steam  energy.  Total  energy  consumption  based  on  floor  area  with  complete  energy

agreement  that  explicitly  includes  renewable  energy  certificates  (“RECs”)  or  Guarantees  of  Origin  (“GOs”),  a  Green-e  Energy  Certified  utility  or  supplier  program  or  other
green  power  products  that  explicitly  include  RECs  or  GOs  or  for  which  Green-e  Energy  Certified  RECs  are  paired  with  grid  electricity.  Percentage  is  based  total  energy
consumption during the applicable year.

(5) Data reported on a like-for-like comparison excludes assets that have been acquired or disposed over the past twenty-four months as of the end of the applicable year.
(6) Eligible portfolio represents our office and residential properties that have had 50% or greater occupancy for 12 consecutive months at any point during the applicable year.
Percentage is based on rentable square footage of our eligible portfolio that has obtained an energy rating and is certified to ENERGY STAR® as of the end of the applicable
year.

(7) Percentage based on gross square footage of portfolio floor area with complete water withdrawal data coverage as of the end of the applicable year. Floor area is considered to
have complete water withdrawal data coverage when water withdrawal data (i.e., amounts withdrawn) is obtained by the Company for the relevant floor area during the fiscal
year, regardless of when such data was obtained.

(8) Water sources include surface water (including water from wetlands, rivers, lakes and oceans), groundwater, rainwater collected directly and stored by the Company, wastewater
obtained  from other entities,  municipal water supplies  or supply  from other water utilities.  Total water withdrawal based on floor area with  complete  water withdrawal data
coverage as of the end of the applicable year.

(9) Percentage  based  on  gross  square  footage  of  portfolio  floor  area  with  complete  Scope  1  GHG  emissions  data  coverage  as  of  the  end  of  the  applicable  year.  Floor  area  is
considered to have complete Scope 1 GHG emissions data coverage when GHG emission data (i.e., amounts emitted) is obtained by the Company for the relevant floor area
during the fiscal year, regardless of when such data was obtained.

(10) Scope 1 emissions represent those produced by consuming onsite natural gas procured by the Company.
(11) Percentage  based  on  gross  square  footage  of  portfolio  floor  area  with  complete  Scope  2  GHG  emissions  data  coverage  as  of  the  end  of  the  applicable  year.  Floor  area  is
considered to have complete Scope 2 GHG emissions data coverage when GHG emission data is obtained by the Company for the relevant floor area during the fiscal year,
regardless of when such data was obtained.

(12) Scope 2 emissions represent those produced by consuming onsite electricity procured by the Company.

We  build  our  current  development  projects  to  Leadership  in  Energy  and  Environmental  Design  (“LEED”)  specifications.  All  of  our  office  development

projects are designed to achieve LEED certification, either LEED Platinum or Gold.

We are actively pursuing LEED certification for approximately 856,000 square feet of office and life science space under construction. In addition, an analysis

of energy and water performance is included in our standard due

11

diligence  process  for  acquisitions,  and  reducing  energy  use  year  over  year  is  a  comprehensive  goal  of  our  operational  strategy.  This  is  accomplished  through
systematic  energy  auditing,  mechanical,  lighting  and  other  building  upgrades,  optimizing  operations  and  engaging  tenants.  During  the  past  few  years,  we  have
significantly  enhanced  the  sustainability  profile  of  our  portfolio,  ending  2020  with  68%  of  our  properties  LEED  certified,  69%  of  our  eligible  stabilized  office
properties ENERGY STAR certified and 100% of our eligible stabilized residential properties ENERGY STAR certified (in each case as a percentage of our total
or eligible rentable square feet as of December 31, 2020).

We identify climate change as a risk to our Company, its tenants and our other stakeholders, an opportunity for long-term value creation and a key driver in
long-term strategic business decisions. These risks and opportunities include transitional risks such as policy, market, technology and reputational concerns, as well
as physical risks, and are a focus area for the board of directors and management.  Climate-related risks and opportunities are governed by the board of directors
through  the  Committee.  In  2018,  the  Committee  endorsed  the  recommendations  of  the  Task  Force  on  Climate-related  Financial  Disclosure  (TCFD)  and  tasked
management with assessing and reporting against climate related risk for the Company. Recognizing the importance of reducing the Company’s greenhouse gas
impact on the environment, in 2018 we committed to achieving carbon neutral operations by December 31, 2020, and we achieved this goal. This means that the
entirety of our scope 1 and scope 2 emissions is offset through a combination of energy efficiency measures and both onsite and offsite renewables. This exceeds
our carbon reduction goals previously validated by Science-Based Targets. Science-Based Targets is a collaboration between the Carbon Disclosure Project, the
United  Nations  Global  Compact,  the  World  Resources  Institute  and  the  World  Wide  Fund  for  Nature,  which  independently  assesses  and  approves  the  carbon
reduction goals of companies.

Significant Tenants

As of December 31, 2020, our 15 largest tenants in terms of annualized base rental revenues represented approximately 49.1% of our total annualized base
rental  revenues,  defined  as  annualized  monthly  contractual  rents  from  existing  tenants  as  of  December  31,  2020.  Annualized  base  rental  revenue  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.

For further information on our 15 largest tenants and the composition of our tenant base, see “Item 2. Properties —Significant Tenants.”

Competition

We compete with several developers, owners, operators and acquirers of office and life science, undeveloped land and other commercial real estate, including
mixed-use  and  residential  real  estate,  many  of  which  own  properties  similar  to  ours  in  the  same  submarkets  in  which  our  properties  are  located.  For  further
discussion of the potential impact of competitive conditions on our business, see “Item 1A. Risk Factors.”

Segment and Geographic Financial Information

During 2020 and 2019, we had one reportable segment, our office and life science properties segment. For information about our office property revenues and
long-lived assets and other financial information, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations —Results
of Operations.”

As of December 31, 2020, all of our properties and development projects were owned and all of our business was conducted in the state of California with the
exception of eight stabilized office properties, one development project in the tenant improvement phase and one future development project located in the state of
Washington.  As  of  December  31,  2020,  all  of  our  properties  and  development  projects  were  100%  owned,  excluding  four  office  properties  owned  by  three
consolidated property partnerships.

12

Human Capital Resources

As of December 31, 2020, we employed 252 people through the Operating Partnership, Kilroy Services, LLC, and Kilroy Realty TRS, Inc. We believe that

relations with our employees are good.

Our human capital development goals and initiatives are focused on enhancing employee growth, satisfaction and wellness while maintaining a diverse and

thriving culture. Several of our human capital development initiatives include the following:

Diversity. We are committed to cultivating a diverse culture of inclusion that makes a positive difference in our employees’ lives and have developed targeted

training to improve workplace diversity, equity and inclusion. As of December 31, 2020, our employees were:

•
•

59% female; 41% male
45% ethnically diverse (i.e., Asian, African American, Hispanic or Latino and other (Native Hawaiian/Pacific Islander and two or more))

Training and Education. We support the continual development of our employees through various training and education programs throughout their tenure at
the  Company,  from  onboarding  to  skill  building  to  leadership  development.  We  also  conduct  annual  performance  and  career  development  reviews  for  all
employees.

Employee Health. The physical and mental health and wellness of our employees is of central importance to our culture. We evaluate our group health and
ancillary benefits annually to ensure our benefits package is robust and conduct an annual wellness and satisfaction survey to help us better tailor our employee
health and wellness programs.

Strong Communities and Healthy Planet. We are deeply aware that our buildings are part of the larger community and that we thrive when the communities

around us thrive. We are proud to make these communities better places to live and work through our volunteerism and philanthropy initiatives.

Fostering Company Culture and Providing Support to Employees During COVID-19 Pandemic. In accordance with local and state government guidance and
social distancing recommendations, almost all of our corporate employees have worked remotely since March 2020. To protect and foster the Company’s culture
during the COVID-19 pandemic, we formed an inter-regional and inter-departmental taskforce that organized challenges, surveys, virtual events and other remote
programming  to  keep  our  employees  connected  while  working  from  home.  See  “Item  7.  Management’s  Discussion  and  Analysis  of  Financial  Condition  and
Results of Operations —Overview and Background—COVID-19 Response.”

Our compensation program is designed to, among other things, attract, retain and incentivize talented and experienced individuals in the highly competitive

West Coast employment and commercial real estate markets. We use a mix of competitive salaries and other benefits to attract and retain these individuals.

13

Environmental Regulations and Potential Liabilities

Government Regulations Relating to the Environment.    Many laws and governmental regulations relating to the environment are applicable to our properties,

and changes in these laws and regulations, or their interpretation by agencies and the courts, occur frequently and may adversely affect us.

Existing conditions at some of our properties.    Independent environmental consultants have conducted Phase I or similar environmental site assessments on
all of our properties. We generally obtain these assessments prior to the acquisition of a property and may later update them as required for subsequent financing of
the property, if a property is slated for disposition, or as requested by a tenant. Consultants are required to perform Phase I assessments to American Society for
Testing and Materials standards then-existing for Phase I site assessments and typically include a historical review, a public records review, a visual inspection of
the surveyed site, and the issuance of a written report. These assessments do not generally include any soil or groundwater sampling or subsurface investigations;
however,  if  a  Phase  I  does  recommend  that  soil  or  groundwater  samples  be  taken  or  other  subsurface  investigations  take  place,  we  generally  perform  such
recommended actions. Depending on the age of the property, the Phase I may have included an assessment of asbestos-containing materials or a separate hazardous
materials survey may have been conducted. For properties where asbestos-containing materials were identified or suspected, an operations and maintenance plan
was generally prepared and implemented.

Historical operations at or near some of our properties, including the presence of underground or above ground storage tanks, various sites uses that involved
hazardous  substances,  the  landfilling  of  hazardous  substances  and  solid  waste,  and  migration  of  contamination  from  other  sites,  may  have  caused  soil  or
groundwater  contamination.  In  some  instances,  the  prior  owners  of  the  affected  properties  conducted  remediation  of  known  contamination  in  the  soils  on  our
properties, we are required to conduct further environmental clean-up and environmental closure activities at certain properties, and residual contamination could
pose environmental, health, and safety risks if not appropriately addressed. We may need to investigate or remediate contaminated soil, soil gas, landfill gas, and
groundwater, and we may also need to conduct landfill closure and post-closure activities, including, for example, the implementation of groundwater and methane
monitoring  systems  and  impervious  cover,  and  the  costs  of  such  work  could  exceed  projected  or  budgeted  amounts.  To  protect  the  health  and  safety  of  site
occupants and others, we may be required to implement and operate safeguards, including, for example, vapor intrusion mitigation systems and building protection
systems to address methane. We may need to modify our methods of construction or face increased construction costs as a result of environmental conditions, and
we may face obligations under agreements with governmental authorities with respect to the management of such environmental conditions. If releases from our
sites  migrate  offsite,  or  if  our  site  redevelopment  activities  cause  or  contribute  to  a  migration  of  hazardous  substances,  neighbors  or  others  could  make  claims
against us, such as for property damage, personal injury, or cost recovery.

As of December 31, 2020, we had accrued environmental remediation liabilities of approximately $71.3 million recorded on our consolidated balance sheets
in connection with certain of our in-process and future development projects. The accrued environmental remediation liabilities represent the remaining costs we
estimate  we  will  incur  prior  to  and  during  the  development  process  at  various  development  acquisition  sites.  These  estimates,  which  we  developed  with  the
assistance of third party experts, consist primarily of the removal of contaminated soil, performing environmental closure activities, constructing remedial systems
and  other  related  costs  since  we  are  required  to  dispose  of  any  existing  contaminated  soil,  and  sometimes  perform  other  environmental  closure  or  remedial
activities,  when we develop new buildings at these sites. It is possible that we could incur additional environmental  remediation  costs in connection with these
development projects.  However, potential additional environmental costs cannot be reasonably estimated at this time and certain changes in estimates could occur
as the site conditions, final project timing, design elements, actual soil conditions and other aspects of the projects, which may depend upon municipal and other
approvals beyond the control of the Company, are determined. See Note 18 “Commitments and Contingencies” to our consolidated financial statements included in
this report for additional information.

Other  than  the  accrued  environmental  liabilities  recorded  in  connection  with  certain  of  our  development  projects,  we are  not  aware  of  any  such  condition,
liability,  or  concern  by  any  other  means  that  would  give  rise  to  material  environmental  liabilities.  However,  our  assessments  may  have  failed  to  reveal  all
environmental conditions, liabilities, or compliance concerns; there may be material environmental conditions, liabilities, or

14

compliance concerns that arose at a property after the review was completed; future laws, ordinances, or regulations may impose material additional environmental
liability;  and  environmental  conditions  at  our  properties  may  be  affected  in  the  future  by  tenants,  third  parties,  or  the  condition  of  land  or  operations  near  our
properties, such as the presence of underground storage tanks or migrating plumes. We cannot be certain that costs of future environmental compliance will not
have  an adverse  effect  on our financial  condition,  results  of operations,  cash flow, the quoted trading  price of our securities,  and our ability  to satisfy our debt
service obligations and to pay dividends and distributions to security holders.

Use of hazardous materials by some of our tenants.    Some of our tenants handle hazardous substances and wastes on our properties as part of their routine
operations. Environmental laws and regulations may subject these tenants, and potentially us, to liability resulting from such activities. We generally require our
tenants in their leases to comply with these environmental laws and regulations and to indemnify us for any related liabilities. As of December 31, 2020, other than
routine  cleaning  materials  and  chemicals  used  in  routine  office  operations,  approximately  4-6%  of  our  tenants  handled  hazardous  substances  and/or  wastes  on
approximately 1-3% of the aggregate square footage of our properties as part of their business operations. These tenants are primarily involved in the life sciences
business. The hazardous substances and wastes are primarily comprised of diesel fuel for emergency generators and small quantities of lab and light manufacturing
chemicals including, but not limited to, alcohol, ammonia, carbon dioxide, cryogenic gases, dichlorophenol, methane, naturalyte acid, nitrogen, nitrous oxide, and
oxygen which are routinely  used by life  science  companies.  We are not aware of any material  noncompliance,  liability,  or claim  relating  to hazardous  or toxic
substances or petroleum products in connection with any of our properties, and management does not believe that on-going activities by our tenants will have a
material adverse effect on our operations.

Costs related to government regulation and private litigation over environmental matters.    Under applicable environmental laws and regulations, we may be
liable for the costs of removal, remediation, or disposal of certain hazardous or toxic substances present or released on our properties. These laws could impose
liability  without  regard  to  whether  we  are  responsible  for,  or  even  knew  of,  the  presence  or  release  of  the  hazardous  materials.  Government  investigations  and
remediation actions may have substantial costs, and the presence or release of hazardous substances on a property could result in governmental clean-up actions,
personal injury actions, or similar claims by private plaintiffs.

Potential  environmental  liabilities  may  exceed  our  environmental  insurance  coverage  limits,  transactional  indemnities  or  holdbacks.    We  carry  what  we
believe  to  be  commercially  reasonable  environmental  insurance.  Our  environmental  insurance  policies  are  subject  to  various  terms,  conditions  and  exclusions.
Similarly, in connection with some transactions we obtain environmental indemnities and holdbacks that may not be honored by the indemnitors, may be less than
the  resulting  liabilities  or  may  otherwise  fail  to  address  the  liabilities  adequately.  Therefore,  we  cannot  provide  any  assurance  that  our  insurance  coverage  or
transactional indemnities will be sufficient or that our liability, if any, will not have a material adverse effect on our financial condition, results of operations, cash
flows, quoted trading price of our securities, and our ability to satisfy our debt service obligations and to pay dividends and distributions to security holders.

SUMMARY RISK FACTORS

The following section sets forth a summary of material factors that may adversely affect our business and operations. For a more extensive discussion of these

factors, see “1A. Risk Factors” contained in this report.

•

•

•

•

The  ongoing  COVID-19  pandemic,  and  restrictions  intended  to  prevent  its  spread,  could  adversely  impact  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.

Global market, economic and geopolitical conditions may adversely affect our business, results of operations, liquidity and financial condition and those
of our tenants.

All of our properties are located in California and greater Seattle, Washington and we may therefore be susceptible to adverse economic conditions and
regulations, as well as natural disasters, in those areas.

Our performance and the market value of our securities are subject to risks associated with our investments in real estate assets and with trends in the real
estate industry.

• We  depend  upon  significant  tenants,  and  the  loss  of  a  significant  tenant  could  adversely  affect  our  financial  condition,  results  of  operations,  ability  to

borrow funds and cash flows.

Downturns in tenants’ businesses may reduce our revenues and cash flows.

A  large  percentage  of  our  tenants  operate  in  a  concentrated  group  of  industries  and  downturns  in  these  industries  could  adversely  affect  our  financial
condition, results of operations and cash flows.

•

•

• We may be unable to renew leases or re-lease available space.

• We are subject to governmental regulations that may affect the development, redevelopment and use of our properties.

• We may not be able to meet our debt service obligations.

•

•

The covenants in the agreements governing the Operating Partnership’s unsecured revolving credit facility, unsecured term loan facility and note purchase
agreements may limit our ability to make distributions to the holders of our common stock.

A downgrade in our credit ratings could materially adversely affect our business and financial condition.

• We face significant competition, which may decrease the occupancy and rental rates of our properties.

•

•

In order to maintain the quality of our properties and successfully compete against other properties, we must periodically spend money to maintain, repair
and renovate our properties, which reduces our cash flows.

Potential casualty losses, such as earthquake losses, may adversely affect our financial condition, results of operations and cash flows.

• We may be unable to complete acquisitions and successfully operate acquired properties.

•

There are significant risks associated with property acquisition, development and redevelopment.

Joint venture investments could be adversely affected by our lack of sole decision-making authority, our reliance on co-venturers’ financial condition, and
disputes between us and our co-venturers and could expose us to potential liabilities and losses.

• We  own  certain  properties  subject  to  ground  leases  and  other  restrictive  agreements  that  limit  our  uses  of  the  properties,  restrict  our  ability  to  sell  or

otherwise transfer the properties and expose us to the loss of the properties if such agreements are breached by us, terminated or not renewed.

• We may invest in securities related to real estate, which could adversely affect our ability to pay dividends and distributions to our security holders.

• We  face  risks  associated  with  security  breaches  through  cyber  attacks,  cyber  intrusions  or  otherwise,  as  well  as  other  significant  disruptions  of  our

information technology (IT) networks and related systems.

An increase in interest rates could increase our interest costs on variable rate debt and new debt and could adversely affect our ability to refinance existing
debt, conduct development, redevelopment and acquisition activity and recycle capital.

The actual density of our undeveloped land holdings and/or any particular land parcel may not be consistent with our potential density estimates.

Loss of our key personnel could harm our operations and financial performance and adversely affect the quoted trading price of our securities.

Our growth depends on external sources of capital that are outside of our control and the inability to obtain capital on terms that are acceptable to us, or at
all, could adversely affect our financial condition and results of operations.

The Chairman of our board of directors and Chief Executive Officer has substantial influence over our affairs.

Loss of the Company’s REIT status would have significant adverse consequences to us and the value of the Company’s common stock.

ITEM 1A.    RISK FACTORS

The following section sets forth material factors that may adversely affect our business and operations. The following factors, as well as the factors discussed
in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations —Factors That May Influence Future Results of Operations”
and other information contained in this report, should be considered in evaluating us and our business.

Risks Related to our Business and Operations

The  ongoing  COVID-19  pandemic,  and  restrictions  intended  to  prevent  its  spread,  could  adversely  impact  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. The ongoing COVID-
19 pandemic which continues to evolve, and restrictions intended to prevent its spread, have impacted the markets in which we conduct our business and where our
tenants are located. All the states where we own properties and/or have development projects (i.e., California and Washington) initially reacted to the COVID-19
pandemic by instituting quarantines, restrictions on travel, “shelter in place” rules, stay-at-home orders, density limitations, social distancing measures, restrictions
on types of business that may continue to operate and/or restrictions on types of construction projects that may continue. Although some state governments and
other authorities were in varying stages of lifting or modifying some of these measures, all the states where we own properties and/or have development projects
have been forced to reinstitute these measures and may, in the future, impose new, more restrictive measures, if the risks, or the perception of the risks, related to
the COVID-19 pandemic worsen at any time. Furthermore, although in certain cases, exceptions are available for essential retail, research and laboratory activities,
essential building services, such as cleaning and maintenance, and certain essential construction projects, there can be no assurance that such exceptions will enable
us to avoid adverse impacts 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. For instance, some of the activities of our parking, retail space and co-working tenants are not covered by the
exceptions listed above, and we have seen weakness and a material reduction in rent

17

collections  from  these  tenants  that  may  continue  for  an  indeterminate  period  pending  a  cessation  of  the  adverse  impacts  from  the  COVID-19  pandemic,  and
restrictions  intended  to  prevent  its  spread.  In  addition,  there  can  be  no  assurance  as  to  how long  restrictions  intended  to  prevent  the  spread  of  COVID-19 may
remain in place in the states and cities where we own properties, and even if such restrictions are lifted, they may be reinstituted at a later date. If such restrictions
remain in place for an extended period of time, we may experience further reductions in rents from our tenants.

Across all property types, we collected approximately 97% of our total gross rent billings for the year ended December 31, 2020, including 100% from all of
our top 15 tenants and as of February 1, 2021, we had collected 95% of our January 2021 total gross rent billings, including 100% from all of our top 15 tenants.
Although we are and will continue to be actively engaged in rent collection efforts related to uncollected rent, as well as working with certain tenants who have
requested rent deferrals (particularly those occupying retail space), we can provide no assurance that such efforts or our efforts in future periods will be successful.
In addition, we are and will continue to be actively engaged in discussions with certain tenants regarding the adverse impacts of the COVID-19 pandemic, and
restrictions intended to prevent its spread, and may afford certain additional accommodations.

In addition, we may be required to continue to comply with “social distancing” at our properties and development projects and we may be subject to certain
conditions, including requiring contractors to develop COVID-19 control, mitigation, and recovery plans and satisfy certain requirements before work can continue
or commence, which may increase costs, perhaps substantially. We expect to comply with any state or local requirements. Our development projects could in the
future be affected by moratoriums on construction. To the extent any city issues a moratorium, we may be subject to such a moratorium unless the applicable state
or city grants an exclusion for these projects because certain of our development projects may qualify as essential construction projects.

The ongoing COVID-19 pandemic, and restrictions intended to prevent its spread, could have significant adverse impacts 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 in a variety of
ways that are difficult to predict. Such adverse impacts could depend on, among other factors:

•

•

•

•

•

•

the  financial  condition  of  our  tenants  -  many  of  which  are  in  the  technology,  media,  healthcare,  life  sciences,  entertainment  and  professional  services
industries - and their ability or willingness to pay rent in full on a timely basis;

state, local, federal and industry-initiated efforts that may adversely affect landlords, including us, and their ability to collect rent and/or enforce remedies
for the failure to pay rent;

our need to defer or forgive rent and restructure leases with our tenants and our ability to do so on favorable terms or at all;

significant job losses in the industries of our tenants, which may decrease demand for our office and retail space, causing market rental rates and property
values to be negatively impacted;

our  ability  to  stabilize  or  lease-up  our  development  projects,  renew  leases  or  re-lease  available  space  in  our  proprieties  on  favorable  terms  or  at  all,
including as a result of a general decrease in demand for our office and retail space, deterioration in the economic and market conditions in the markets in
which we own properties or due to restrictions intended to prevent the spread of COVID-19 that frustrate our leasing activities;

a severe and prolonged disruption and instability in the global financial markets, including the debt and equity capital markets, all of which have already
experienced and may continue to experience significant volatility, or deterioration in credit and financing conditions, may affect our or our tenants’ ability
to access capital necessary to fund our respective business operations or replace or renew maturing liabilities on a timely basis, on attractive terms or at all
and may adversely affect the valuation of financial assets and liabilities, any of which could affect our and our tenants’ ability to meet liquidity and capital
expenditure requirements;

18

•

•

•

•

•

•

•

a refusal or failure of one or more lenders under our revolving credit facility to fund their respective financing commitments to us may affect our ability to
access capital necessary to fund our business operations and to meet our liquidity and capital expenditure requirements;

the ability of potential buyers of properties identified for potential future capital recycling transactions to obtain debt financing, which has been and may
continue to be constrained for some potential buyers;

a  reduction  in  the  values  of  our  properties  that  could  result  in  impairments  or  limit  our  ability  to  dispose  of  them  at  attractive  prices  or  obtain  debt
financing secured by our properties;

complete or partial shutdowns of one or more of our tenants’ manufacturing facilities or distribution centers, temporary or long-term disruptions in our
tenants’ supply chains from local, national and international suppliers or delays in the delivery of products, services or other materials necessary for our
tenants’ operations, which could force our tenants to reduce, delay or eliminate offerings of their products and services, reduce or eliminate their revenues
and liquidity and/or result in their bankruptcy or insolvency;

our ability to avoid delays or cost increases associated with building materials  or construction services necessary for construction that could adversely
impact our ability to continue or complete construction as planned, on budget or at all;

our and our tenants’ ability to manage our respective businesses to the extent our and their management or personnel are impacted in significant numbers
by the COVID-19 pandemic and are not willing, available or allowed to conduct work; and

our  and  our  tenants’  ability  to  ensure  business  continuity  in  the  event  our  continuity  of  operations  plan  is  not  effective  or  improperly  implemented  or
deployed during the COVID-19 pandemic.

The  rapid  development  and  fluidity  of  this  situation  precludes  any  prediction  as  to  the  ultimate  adverse  impact  of  the  COVID-19  pandemic  or  restrictions
intended to prevent its spread. Nevertheless, the ongoing COVID-19 pandemic, and restrictions intended to prevent its spread, and the current financial, economic
and capital markets environment and future developments in these and other areas present material risks and uncertainties with respect to 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
and could also have a material adverse effect on the market value of our securities. Moreover, to the extent any of these risks and uncertainties adversely impact us
in the ways described above or otherwise, they may also have the effect of heightening many of the other risks set forth in this “Risk Factors” section.

Global market, economic and geopolitical conditions may adversely affect our business, results of operations, liquidity and financial condition and those of
our  tenants.  Our  business  may  be  adversely  affected  by  global  market,  economic  and  geopolitical  conditions,  including  general  global  economic  and  political
uncertainty and dislocations in the credit markets. If these conditions become more volatile or worsen, our and our tenant’s business, results of operations, liquidity
and financial condition and those of our tenants may be adversely affected as a result of the following consequences, among others:

•

•

•

the  financial  condition  of  our  tenants,  many  of  which  are  technology;  life  science  and  healthcare;  finance,  insurance  and  real  estate;  media  and
professional  business  and  other  service  firms,  may  be  adversely  affected,  which  may  result  in  tenant  defaults  under  leases  due  to  bankruptcy,  lack  of
liquidity, operational failures or for other reasons;

significant job losses in the financial and professional services industries may occur, which may decrease demand for our office space, causing market
rental rates and property values to be negatively impacted;

our  ability  to  obtain  financing  on  terms  and  conditions  that  we  find  acceptable,  or  at  all,  may  be  limited,  which  could  reduce  our  ability  to  pursue
acquisition and development opportunities and refinance existing debt, reduce our returns from our acquisition and development activities and increase
our future interest expense;

19

•

•

reduced values of our properties may limit our ability to dispose of assets at attractive prices or to obtain debt financing secured by our properties and may
reduce the availability of unsecured loans; and

one or more lenders under the Operating Partnership’s unsecured revolving credit facility could refuse to fund their financing commitment to us or could
fail and we may not be able to replace the financing commitment of any such lenders on favorable terms, or at all.

All  of  our  properties  are  located  in  California  and  greater  Seattle,  Washington  and  we  may  therefore  be  susceptible  to  adverse  economic  conditions  and
regulations, as well as natural disasters, in those areas. Because all of our properties are concentrated in California and greater Seattle, we may be exposed to
greater  economic  risks  than  if  we  owned  a  more  geographically  dispersed  portfolio.  Further,  within  California,  our  properties  are  concentrated  in  Greater  Los
Angeles, San Diego County and the San Francisco Bay Area, exposing us to risks associated with those specific areas. We are susceptible to adverse developments
in  the  economic  and  regulatory  environments  of  California  and  greater  Seattle  (such  as  periods  of  economic  slowdown  or  recession,  business  layoffs  or
downsizing, industry slowdowns, relocations of businesses, increases in real estate and other taxes, costs of complying with governmental regulations or increased
regulation and other factors), as well as adverse weather conditions and natural disasters that occur in those areas (such as earthquakes, wind, landslides, droughts,
fires and other events). For example, many of our assets are in zones that have been impacted by drought and, as such, face the risk of increased water costs and
potential fines and/or penalties for high consumption. In addition, California is also regarded as more litigious and more highly regulated and taxed than many
other states, which may reduce demand for office space in California.

Any adverse developments in the economy or real estate market in California and the surrounding region, or in greater Seattle or any decrease in demand for
office space resulting from the California or greater Seattle regulatory or business environment could impact our ability to generate revenues sufficient to meet our
operating expenses or other obligations, which would adversely impact our financial condition, results of operations, cash flows, the quoted trading price of our
securities and our ability to satisfy our debt service obligations and to pay dividends and distributions to our security holders.

Our performance and the market value of our securities are subject to risks associated with our investments in real estate assets and with trends in the real
estate industry. Our economic performance and the value of our real estate assets and, consequently the market value of the Company’s securities, are subject to
the risk that our properties may not generate revenues sufficient to meet our operating expenses or other obligations. A deficiency of this nature would adversely
impact our financial condition, results of operations, cash flows, the quoted trading price of our securities, and our ability to satisfy our debt service obligations and
to pay dividends and distributions to our security holders.

Events and conditions applicable to owners and operators of real estate that are beyond our control and could impact our economic performance and the value

of our real estate assets may include:

•

•

•

•

•

•

•

local  oversupply  or  reduction  in  demand  for  office,  mixed-use  or  other  commercial  space,  which  may  result  in  decreasing  rental  rates  and  greater
concessions to tenants;

inability to collect rent from tenants;

vacancies or inability to rent space on favorable terms or at all;

inability to finance property development and acquisitions on favorable terms or at all;

increased operating costs, including insurance premiums, utilities and real estate taxes;

costs of complying with changes in governmental regulations;

the relative illiquidity of real estate investments;

20

•

•

•

•

•

declines in real estate asset valuations, which may limit our ability to dispose of assets at attractive prices or obtain or maintain debt financing;

changing submarket demographics;

changes in space utilization by our tenants due to technology, economic conditions and business culture;

the development of harmful mold or other airborne toxins or contaminants that could damage our properties or expose us to third-party liabilities; and

property damage resulting from seismic activity or other natural disasters.

We depend upon significant tenants, and the loss of a significant tenant could adversely affect our financial condition, results of operations, ability to borrow
funds  and cash  flows.  As  of  December  31,  2020,  our  15  largest  tenants  represented  approximately  49.1%  of  total  annualized  base  rental  revenues.  See  further
discussion on the composition of our tenants by industry and our largest tenants under “Item 2. Properties —Significant Tenants.”

Our  financial  condition,  results  of  operations,  ability  to  borrow  funds  and  cash  flows  would  be  adversely  affected  if  any  of  our  significant  tenants  fails  to

renew its lease(s), renew its lease(s) on terms less favorable to us, or becomes bankrupt or insolvent or otherwise unable to satisfy its lease obligations.

Downturns in tenants’ businesses may reduce our revenues and cash flows. For the year ended December 31, 2020, we derived approximately 99.3% of our
revenues from rental income. A tenant may experience a downturn in its business, which may weaken its financial condition and result in its failure to make timely
rental payments or result in defaults under our leases. In the event of default by a tenant, we may experience delays in enforcing our rights as landlord and may
incur substantial costs in protecting our investment.

The bankruptcy or insolvency of a major tenant also may adversely affect the income produced by our properties. If any tenant becomes a debtor in a case
under federal bankruptcy law, we cannot evict the tenant solely because of the bankruptcy. In addition, the bankruptcy court might permit the tenant to reject and
terminate  its  lease  with  us.  Our  claim  against  the  tenant  for  unpaid  and  future  rent  could  be  subject  to  a  statutory  cap  that  might  be  substantially  less  than  the
remaining rent actually owed under the lease. Therefore, our claim for unpaid rent would likely not be paid in full. Any losses resulting from the bankruptcy of any
of our existing tenants could adversely impact our financial condition, results of operations, cash flows, the quoted trading price of our securities, and our ability to
satisfy our debt service obligations and to pay dividends and distributions to our security holders.

A  large  percentage  of  our  tenants  operate  in  a  concentrated  group  of  industries  and  downturns  in  these  industries  could  adversely  affect  our  financial
condition, results of operations and cash flows. As of December 31, 2020, as a percentage of our annualized base rental revenue for the stabilized portfolio, 58% of
our tenants operated in the technology industry, 13% in the life science and health care industries, 11% in the media industry, 7% in the finance, insurance and real
estate  industries,  4%  in  the  professional,  business  and  other  services  industries  and  7%  in  other  industries.  As  we  continue  our  development  and  potential
acquisition activities in markets populated by knowledge and creative based tenants in the technology and media industries, our tenant mix could become more
concentrated,  further  exposing  us  to  risks  associated  with  those  industries.  For  a  further  discussion  of  the  composition  of  our  tenants  by  industry,  see  “Item  2.
Properties —Significant Tenants.” An economic downturn in any of these industries, or in any industry in which a significant number of our tenants currently or
may in the future operate, could negatively impact the financial condition of such tenants and cause them to fail to make timely rental payments or default on lease
obligations, fail to renew their leases or renew their leases on terms less favorable to us, become bankrupt or insolvent, or otherwise become unable to satisfy their
obligations to us. As a result, a downturn in an industry in which a significant number of our tenants operate could adversely affect our financial conditions, result
of operations and cash flows.

We may be unable to renew leases or re-lease available space. Most of our income is derived from the rent earned from our tenants. We had office space
representing approximately 8.8% of the total square footage of our stabilized office properties that was not occupied as of December 31, 2020. In addition, leases
representing approximately 4.4% and 6.6% of the leased rentable square footage of our properties are scheduled to expire in 2021

21

and  2022,  respectively.  Of  the  leases  scheduled  to  expire  in  2021  and  2022,  21%  and  4%  of  the  rentable  square  footage  scheduled  to  expire  was  re-leased,
respectively, as of December 31, 2020. Above market rental rates on some of our properties may force us to renew or re-lease expiring leases at rates below current
lease rates. We cannot provide any assurance that leases will be renewed, available space will be re-leased or that our rental rates will be equal to or above the
current  rental  rates.  If  the  average  rental  rates  for  our  properties  decrease,  existing  tenants  do  not  renew  their  leases,  or  available  space  is  not  re-leased,  our
financial condition, results of operations, cash flows, the quoted trading price of our securities, and our ability to satisfy our debt service obligations and to pay
dividends  and  distributions  to  our  security  holders  could  be  adversely  affected.  For  additional  information  on  our  scheduled  lease  expirations,  see  “Item  7.
Management’s Discussion and Analysis of Financial Condition and Results of Operations —Factors That May Influence Future Results of Operations.”

We are subject to governmental regulations that may affect the development, redevelopment and use of our properties. Our properties are subject to regulation
under  federal  laws,  such  as  the  Americans  with  Disabilities  Act  of  1990  (the  “ADA”),  pursuant  to  which  all  public  accommodations  must  meet  federal
requirements related to access and use by disabled persons, and state and local laws addressing earthquake, fire and life safety requirements. Although we believe
that our properties substantially comply with requirements under applicable governmental regulations, none of our properties have been audited or investigated for
compliance by any regulatory agency. If we were not in compliance with material provisions of the ADA or other regulations affecting our properties, we might be
required to take remedial action, which could include making modifications or renovations to our properties. Federal, state, or local governments may also enact
future laws and regulations that could require us to make significant modifications or renovations to our properties. If we were to incur substantial costs to comply
with the ADA or any other regulations, our financial condition, results of operations, cash flows, the quoted trading price of our securities, and our ability to satisfy
our debt service obligations and to pay dividends and distributions to our security holders could be adversely affected.

Our properties are subject  to land use rules and regulations  that govern our development,  redevelopment  and use of our properties,  such as Title 24 of the
California  Code  of  Regulations  (“Title  24”),  which  prescribes  building  energy  efficiency  standards  for  residential  and  nonresidential  buildings  in  the  State  of
California. If we were not in compliance with material provisions of Title 24 or other regulations affecting our properties, we might be required to take remedial
action, which could include making modifications or renovations to our properties. Changes in the existing land use rules and regulations and approval process that
restrict or delay our ability to develop, redevelop or use our properties (such as potential restrictions on the use and/or density of new developments, water use and
other uses and activities) or that prescribe additional standards could have an adverse effect on our financial position, results of operations, cash flows, the quoted
trading price of our securities, and our ability to satisfy our debt service obligations and to pay dividends and distributions to our security holders.

We  face  significant  competition,  which  may  decrease  the  occupancy  and  rental  rates  of  our  properties.  We  compete  with  several  developers,  owners  and
operators of office, undeveloped land and other commercial real estate, including mixed-use and residential real estate, many of which own properties similar to
ours in the same submarkets in which our properties are located but which have lower occupancy rates than our properties. Therefore, our competitors have an
incentive  to  decrease  rental  rates  until  their  available  space  is  leased.  If  our  competitors  offer  space  at  rental  rates  below  the  rates  currently  charged  by  us  for
comparable  space, we may be pressured  to reduce  our rental  rates  below those currently  charged in order to retain  tenants when our tenant leases  expire. As a
result, our financial condition, results of operations, cash flow, the quoted trading price of our securities, and our ability to satisfy our debt service obligations and
to pay dividends and distributions to our security holders may be adversely affected.

In order to maintain the quality of our properties and successfully compete against other properties, we must periodically spend money to maintain, repair
and  renovate  our  properties,  which  reduces  our  cash  flows. If  our  properties  are  not  as  attractive  to  current  and  prospective  tenants  in  terms  of  rent,  services,
condition or location as properties owned by our competitors, we could lose tenants or suffer lower rental rates. As a result, we may from time to time be required
to make significant capital expenditures to maintain the competitiveness of our properties. There can be no assurances that any such expenditure would result in
higher occupancy or higher rental rates, or deter existing tenants from relocating to properties owned by our competitors.

22

Potential  casualty  losses,  such  as  earthquake  losses,  may  adversely  affect  our  financial  condition,  results  of  operations  and  cash  flows.  We  carry
comprehensive liability, fire, extended coverage, rental loss, and terrorism insurance covering all of our properties. Management believes the policy specifications
and insured limits are appropriate given the relative risk of loss, the cost of the coverage and industry practice. We do not carry insurance for generally uninsurable
losses  such  as  loss  from  riots  or  acts  of  God.  In  addition,  all  of  our  properties  are  located  in  earthquake-prone  areas.  We  carry  earthquake  insurance  on  our
properties in an amount and with deductibles that management believes are commercially reasonable. However, the amount of our earthquake insurance coverage
may not be sufficient to cover losses from earthquakes. We may also discontinue earthquake insurance on some or all of our properties in the future if the cost of
premiums for earthquake insurance exceeds the value of the coverage discounted for the risk of loss. If we experience a loss that is uninsured or which exceeds
policy  limits,  we  could  lose  the  capital  invested  in  the  damaged  properties  as  well  as  the  anticipated  future  cash  flows  from  those  properties.  Further,  if  the
damaged properties are subject to recourse indebtedness, we would continue to be liable for the indebtedness, even if the properties were irreparable.

We may not be able to rebuild our existing properties to their existing specifications if we experience a substantial or comprehensive loss of such properties.
In  the  event  that  we  experience  a  substantial  or  comprehensive  loss  of  one  of  our  properties,  we  may  not  be  able  to  rebuild  such  property  to  its  existing
specifications.  Further,  reconstruction  or  improvement  of  such  property  could  potentially  require  significant  upgrades  to  meet  zoning  and  building  code
requirements or be subject to environmental and other legal restrictions.

Our business is subject to risks associated with climate change and our sustainability strategies. Climate change could trigger extreme weather and changes in
precipitation, temperature, and air quality, all of which may result in physical damage to, or a decrease in demand for, our properties located in the areas affected
by these conditions. Should the impact of climate change be severe or occur for lengthy periods of time, our financial condition or results of operations would be
adversely affected.

Recognizing  the  importance  of  climate  change  and  reducing  our  greenhouse  gas  impact  on  the  environment,  as  part  of  our  sustainability  strategies,  we
achieved carbon neutral operations in 2020 per the commitment we made in 2018. This means that the entirety of our scope 1 and scope 2 emissions are now offset
through a combination of energy efficiency measures and both onsite and offsite renewables. Scope 1 emissions represent those produced by onsite natural gas
consumption procured by us, and Scope 2 emissions represent  those produced by onsite electricity  consumption procured by us. Our own efforts  to reduce  our
greenhouse  gas  impact  on  the  environment  and/or  comply  with  changes  in  federal  and  state  laws  and  regulations  on  climate  change  could  result  in  significant
capital expenditures to improve the energy efficiency of our existing properties or properties we may acquire. Changes to such law and regulations could also result
in increased operating costs at our properties (for example, through increased utility costs). Moreover, if we are unable to maintain carbon neutral operations or
comply with laws and regulations on climate change, our reputation among our tenants and investors may be damaged and we may incur fines and/or penalties.

Our properties are located in West Coast markets of the United States. To the extent that climate change impacts changes in weather patterns, our markets
could experience increases in extreme weather and rising sea levels. For example, many of our assets are in zones that have been impacted by drought and, as such,
face the risk of increased water costs and potential fines and/or penalties for high consumption.  We endeavor to understand these risks through the use of climate
change modeling analysis. We mitigate risks uncovered through this analysis through, for example, comprehensive, proactive water reduction efforts throughout
our portfolio, including domestic fixture upgrades, cooling tower optimizations, a comprehensive leak detection program and irrigation systems retrofits. We also
incorporate green lease language into 100% of our new leases, including a cost recovery clause for resource-efficiency related capital expenditures in full-service
gross leases, which aim to align our and our tenant’s interests on energy, water and waste efficiency.  In addition, we are building our current development projects
to LEED specifications, and all of our office development projects are now designed to achieve LEED certification, either LEED Platinum or Gold.  However,
there can be no assurances that we will successfully mitigate the risk of increased water costs and potential fines and/or penalties for high consumption or that we
will be able to fully recoup any capital expenditures we incur in connection with our green leases.  Moreover, there can be no assurance that our development
projects  will  be  able  to  achieve  the  anticipated  LEED  certifications  or  that  any  of  our  sustainability  strategies  will  result  in  reduced  operating  costs,  higher
occupancy or higher rental rates or deter our existing tenants from relocating to properties owned by our competitors. Over time, these conditions could result in

23

declining  demand  for  space  at  our  properties  or  in  our  inability  to  operate  the  buildings  as  currently  intended  or  at  all.  Climate  change  may  also  have  indirect
effects on our business by increasing the cost of, or decreasing the availability of, property insurance on terms we find acceptable or at all, or by increasing the cost
of energy or water. There can be no assurance that climate change will not have a material adverse effect on our properties, operations or business.

We  are  subject  to  environmental  and  health  and  safety  laws  and  regulations,  and  any  costs  to  comply  with,  or  liabilities  arising  under,  such  laws  and
regulations could be material. As an owner, operator, manager, acquirer and developer of real properties, we are subject to environmental and health and safety
laws and regulations. Certain of these laws and regulations impose joint and several liability, without regard to fault, for investigation and clean-up costs on current
and  former  owners  and  operators  of  real  property  and  persons  who  have  disposed  of  or  released  hazardous  substances  into  the  environment.  At  some  of  our
properties, there are asbestos-containing materials, or tenants routinely handle hazardous substances as part of their operations. In addition, historical operations
and conditions, including the presence of underground storage tanks, various site uses that involved hazardous substances, the landfilling of hazardous substances
and solid waste, and migration of contamination from other sites, have caused soil or groundwater contamination at or near some of our properties. Although we
believe that the prior owners of the affected properties or other persons may have conducted remediation of known contamination at many of these properties, not
all such contamination has been remediated, further clean-up or environmental closure activities at certain of these properties is or may be required, and residual
contamination could pose environmental, health, and safety risks if not appropriately addressed. We may need to investigate or remediate contaminated soil, soil
gas,  landfill  gas,  and  groundwater,  and  we  may  also  need  to  conduct  landfill  closure  and  post-closure  activities,  including,  for  example,  the  implementation  of
groundwater and methane monitoring systems and impervious cover, and the costs of such work could exceed projected or budgeted amounts. To protect the health
and safety of site occupants and others, we may be required to implement and operate safeguards, including, for example, vapor intrusion mitigation systems and
building  protection  systems  to  address  methane.  We  may  need  to  modify  our  methods  of  construction  or  face  increased  construction  costs  as  a  result  of
environmental conditions, and we may face obligations under agreements with governmental authorities with respect to the management of such environmental
conditions. If releases from our sites migrate offsite, or if our site redevelopment activities cause or contribute to a migration of hazardous substances, neighbors or
others could make claims against us, such as for property damage, personal injury, cost recovery, or natural resources damage. As of December 31, 2020, we had
accrued  environmental  remediation  liabilities  of  approximately  $71.3  million  recorded  on  our  consolidated  balance  sheets  in  connection  with  certain  of  our  in-
process  and  future  development  projects.  The  accrued  environmental  remediation  liabilities  represent  the  costs  we  estimate  we  will  incur  when  we  commence
development  at  various  development  acquisition  sites.  These  estimates,  which  we  developed  with  the  assistance  of  third  party  experts,  consist  primarily  of  the
removal of contaminated soil, performing environmental closure activities, construction remedial systems, and other related costs since we are required to dispose
of any existing contaminated soil, and sometimes perform other environmental closure or remedial activities, when we develop new office properties as these sites.
It  is  possible  that  we  could  incur  additional  environmental  remediation  costs  in  connection  with  future  development  projects.  However,  potential  additional
environmental costs cannot be reasonably estimated at this time and certain changes in estimates could occur as the site conditions, final project timing, design
elements, actual soil conditions and other aspects of the projects, which may depend upon municipal and other approvals beyond the control of the Company, are
determined. Unknown or unremediated contamination or compliance with existing or new environmental or health and safety laws and regulations could require us
to incur costs or liabilities that could be material. See “Item 1. Business —Environmental Regulations and Potential Liabilities” and Note 18 “Commitments and
Contingencies” to our consolidated financial statements included in this report.

We may be unable to complete acquisitions and successfully operate acquired properties. We continually evaluate the market of available properties and may
continue to acquire office or mixed-use properties and undeveloped land when strategic opportunities exist. Our ability to acquire properties on favorable terms and
successfully operate them is subject to various risks, including the following:

•

we may potentially be unable to acquire a desired property because of competition from other real estate investors with significant capital, including both
publicly traded and private REITs, institutional investment funds and other real estate investors;

24

•

•

•

•

•

•

•

even if we are able to acquire a desired property, competition from other real estate investors may significantly increase the purchase price;

even if we enter into agreements for the acquisition of a desired property, we may be unable to complete such acquisitions because they remain subject to
customary conditions to closing, including the completion of due diligence investigations to management’s satisfaction;

we may be unable to finance acquisitions on favorable terms or at all;

we may spend more than budgeted amounts in operating costs or to make necessary improvements or renovations to acquired properties;

we may lease acquired properties at economic lease terms different than projected;

we may acquire properties that are subject to liabilities for which we may have limited or no recourse; and

we may be unable to complete an acquisition after making a nonrefundable deposit and incurring certain other acquisition-related costs.

If we cannot finance property acquisitions on favorable terms or operate acquired properties to meet financial expectations, our financial condition, results of
operations, cash flows, the quoted trading price of our securities and our ability to satisfy our debt service obligations and to pay dividends and distributions to our
security holders could be adversely affected.

There are significant  risks  associated  with property  acquisition,  development  and redevelopment.  We may be unable to successfully  complete  and operate

acquired, developed and redeveloped properties, and it is possible that:

•

•

•

•

•

•

•

•

we  may  be  unable  to  lease  acquired,  developed  or  redeveloped  properties  on  lease  terms  projected  at  the  time  of  acquisition,  development  or
redevelopment or within budgeted timeframes;

the  operating  expenses  at  acquired,  developed  or  redeveloped  properties  may  be  greater  than  projected  at  the  time  of  acquisition,  development  or
redevelopment, resulting in our investment being less profitable than we expected;

we may not commence or complete development or redevelopment properties on schedule or within budgeted amounts or at all;

we may not be able to develop or redevelop the estimated square footage and other features of our development and redevelopment properties;

we may suspend development or redevelopment projects after construction has begun due to changes in economic conditions or other factors, and this
may result in the write-off of costs, payment of additional costs or increases in overall costs when the development or redevelopment project is restarted;

we may  expend  funds  on  and  devote  management’s  time  to  acquisition,  development  or  redevelopment  properties  that  we may  not  complete  and  as  a
result we may lose deposits or fail to recover expenses already incurred;

we  may  encounter  delays  or  refusals  in  obtaining  all  necessary  zoning,  land  use,  and  other  required  entitlements,  and  building,  occupancy,  and  other
required governmental permits and authorizations;

we  may  encounter  delays  or  unforeseen  cost  increases  associated  with  building  materials  or  construction  services  resulting  from  trade  tensions,
disruptions, tariffs, duties or restrictions or an outbreak of an epidemic or pandemic;

25

•

•

we may encounter delays, refusals, unforeseen cost increases and other impairments resulting from third-party litigation; and

we may fail to obtain the financial results expected from properties we acquire, develop or redevelop.

If one or more of these events were to occur in connection with our acquired properties, undeveloped land, or development or redevelopment properties under
construction,  we  could  be  required  to  recognize  an  impairment  loss.  These  events  could  also  have  an  adverse  impact  on  our  financial  condition,  results  of
operations, cash flow, the quoted trading price of our securities, and our ability to satisfy our debt service obligations and to pay dividends and distributions to our
security holders.

While we historically have acquired, developed and redeveloped office properties in California markets, over the past few years we have acquired properties
in greater Seattle, where we currently have eight stabilized office properties, one development project in the tenant improvement phase and one future development
project, and may in the future acquire, develop or redevelop properties for other uses and expand our business to other geographic regions where we expect the
development or acquisition of property to result in favorable risk-adjusted returns on our investment. Presently, we do not possess the same level of familiarity
with other outside markets, which could adversely affect our ability to acquire, develop or redevelop properties or to achieve expected performance.

We face risks associated with the development of mixed-use commercial properties. We are currently developing, and in the future may develop, properties
either alone or through joint ventures that are known as “mixed-use” developments. This means that in addition to the development of office space, the project may
also include space for residential, retail or other commercial purposes. Generally, we have less experience developing and managing non-office/life science real
estate.  As  a  result,  if  a  development  project  includes  non-office/life  science  space,  we  may  develop  that  space  ourselves  or  seek  to  partner  with  a  third-party
developer with more experience. If we do not partner with such a developer, or if we choose to develop the space ourselves, we would be exposed to specific risks
associated  with  the  development  and  ownership  of  non-office/life  science  real  estate.  In  addition,  if  we  elect  to  participate  in  the  development  through  a  joint
venture,  we  may  be  exposed  to  the  risks  associated  with  the  failure  of  the  other  party  to  complete  the  development  as  expected,  which  could  require  that  we
identify  another  joint  venture  partner  and/or  complete  the  project  ourselves  (including  providing  any  necessary  financing).  In  the case  of residential  properties,
these risks include competition  for prospective  tenants from  other operators  whose properties  may be perceived  to offer a better  location  or better  amenities  or
whose rent may be perceived as a better value given the quality, location and amenities that the tenant seeks. With residential properties, we will also compete
against apartments, condominiums and single-family homes that are for sale or rent. Because we have less experience with residential properties, we may retain
third parties to manage these properties. If we decide to wholly own a non-office project and hire a third-party manager, we could be dependent on that party and
its key personnel to provide services to us, and we may not find a suitable replacement if the management agreement is terminated, or if key personnel leave or
otherwise become unavailable to us.

Joint venture investments  could be adversely  affected  by our lack of sole decision-making  authority, our reliance  on co-venturers'  financial  condition, and
disputes between us and our co-venturers and could expose us to potential liabilities and losses. In addition to the 100 First LLC and 303 Second LLC strategic
ventures and the Redwood City Partners, LLC venture, we may continue to co-invest in the future with third parties through partnerships, joint ventures or other
entities, or through acquiring non-controlling interests in, or sharing responsibility for, managing the affairs of a property, partnership, joint venture or other entity,
which may subject us to risks that may not be present with other methods of ownership, including the following:

•

•

we would not be able to exercise sole decision-making authority regarding the property, partnership, joint venture or other entity, which would allow for
impasses on decisions that could restrict our ability to sell or transfer our interests in such entity or such entity’s ability to transfer or sell its assets;

partners  or  co-venturers  might  become  bankrupt  or  fail  to  fund  their  share  of  required  capital  contributions,  which  could  delay  construction  or
development of a property or increase our financial commitment to the partnership or joint venture;

26

•

•

•

•

partners or co-venturers may pursue economic or other business interests, policies or objectives that are competitive or inconsistent with ours;

if we become a limited partner or non-managing member in any partnership or limited liability company, and such entity takes or expects to take actions
that could jeopardize our status as a REIT or require us to pay tax, we may be forced to dispose of our interest in such entity;

disputes between us and partners or co-venturers may result in litigation or arbitration that would increase our expenses and prevent our officers and/or
directors from focusing their time and effort on our business; and

we may, in certain circumstances, be liable for the actions of our third-party partners or co-venturers.

We  own  certain  properties  subject  to  ground  leases  and  other  restrictive  agreements  that  limit  our  uses  of  the  properties,  restrict  our  ability  to  sell  or
otherwise transfer the properties and expose us to the loss of the properties if such agreements are breached by us, terminated or not renewed. As of December 31,
2020,  we  owned  fourteen  office  buildings,  located  on  various  land  parcels  and  in  various  regions,  which  we  lease  individually  on  a  long-term  basis.  As  of
December 31, 2020, we had approximately 2.0 million aggregate rentable square feet, or 14.0% of our total stabilized portfolio, of rental space located on these
leased parcels and we may in the future invest in additional properties that are subject to ground leases or other similar restrictive arrangements. Many of these
ground leases and other restrictive agreements impose significant limitations on our uses of the subject property, restrict our ability to sell or otherwise transfer our
interests  in  the  property  or  restrict  our  leasing  of  the  property.  These  restrictions  may  limit  our  ability  to  timely  sell  or  exchange  the  properties,  impair  the
properties’ value or negatively impact our ability to find suitable tenants for the properties. In addition, if we default under the terms of any particular lease, we
may lose the ownership rights to the property subject to the lease. Upon expiration of a lease, we may not be able to renegotiate a new lease on favorable terms, if
at  all.  The  loss  of  the  ownership  rights  to  these  properties  or  an  increase  of  rental  expense  could  have  an  adverse  effect  on  our  financial  condition,  results  of
operations, cash flow, the quoted trading price of our securities, and our ability to satisfy our debt service obligations and to pay dividends and distributions to our
security holders.

Real estate assets are illiquid, and we may not be able to sell our properties when we desire. Our investments in our properties are relatively illiquid, limiting
our  ability  to  sell  our  properties  quickly  in  response  to  changes  in  economic  or  other  conditions.  In  addition,  the  Code  generally  imposes  a  100%  prohibited
transaction tax on the Company on profits derived from sales of properties held primarily for sale to customers in the ordinary course of business, which effectively
limits our ability to sell properties other than on a selected basis. These restrictions on our ability to sell our properties could have an adverse effect on our financial
condition, results of operations, cash flow, the quoted trading price of our securities, and our ability to satisfy our debt service obligations and to pay dividends and
distributions to our security holders.

We may invest in securities related to real estate, which could adversely affect our ability to pay dividends and distributions to our security holders. We may
purchase  securities  issued  by  entities  that  own  real  estate  and  may,  in  the  future,  also  invest  in  mortgages.  In  general,  investments  in  mortgages  are  subject  to
several risks, including:

•

•

•

borrowers may fail to make debt service payments or pay the principal when due;

the value of the mortgaged property may be less than the principal amount of the mortgage note securing the property; and

interest rates payable on the mortgages may be lower than our cost for the funds used to acquire these mortgages.

Owning these securities may not entitle us to control the ownership, operation and management of the underlying real estate. In addition, we may have no

control over the distributions with respect to these securities, which could adversely affect our ability to pay dividends and distributions to our security holders.

27

We face risks associated with short-term liquid investments. From time to time, we have significant cash balances that we invest in a variety of short-term
investments that are intended to preserve principal value and maintain a high degree of liquidity while providing current income. These investments may include
(either directly or indirectly):

•

•

•

•

•

•

•

•

direct obligations issued by the U.S. Treasury;

obligations issued or guaranteed by the U.S. government or its agencies;

taxable municipal securities;

obligations (including certificates of deposits) of banks and thrifts;

commercial paper and other instruments consisting of short-term U.S. dollar denominated obligations issued by corporations and banks;

repurchase agreements collateralized by corporate and asset-backed obligations;

both registered and unregistered money market funds; and

other highly rated short-term securities.

Investments in these securities and funds are not insured against loss of principal. Under certain circumstances we may be required to redeem all or part of our
investment, and our right to redeem some or all of our investment may be delayed or suspended. In addition, there is no guarantee that our investments in these
securities or funds will be redeemable at par value. A decline in the value of our investment or a delay or suspension of our right to redeem may have a material
adverse effect on our results of operations or financial condition.

Our  property  taxes  could  increase  due  to  reassessment  or  property  tax  rate  changes. We  are  required  to  pay  state  and  local  taxes  on  our  properties.  In
addition, the real property taxes on our properties may increase as our properties are reassessed by taxing authorities or as property tax rates change. For example,
under a current California law commonly referred to as “Proposition 13,” property tax reassessment generally occurs as a result of a “change in ownership” of a
property,  as  specifically  defined  for  purposes  of  those  rules.  Because  the  property  taxing  authorities  may  not  determine  whether  there  has  been  a  “change  in
ownership”  or  the  actual  reassessed  value  of  a  property  for  a  period  of  time  after  a  transaction  has  occurred,  we  may  not  know  the  impact  of  a  potential
reassessment for a considerable amount of time following a particular transaction or construction of a new property. Therefore, the amount of property taxes we are
required to pay could increase substantially from the property taxes we currently pay or have paid in the past, including on a retroactive basis. In addition, from
time  to  time  voters  and  lawmakers  have  announced  initiatives  to  repeal  or  amend  Proposition  13  to  eliminate  its  application  to  commercial  property  and/or
introduce split tax roll legislation. Such initiatives, if successful, would increase the assessed value and/or tax rates applicable to commercial property in California,
including our properties. An increase in the assessed value of our properties or our property tax rates could adversely impact our financial condition, results of
operations, cash flows, the quoted trading price of our securities, and our ability to satisfy our debt service obligations and to pay dividends and distributions to our
security holders.

Our business could be adversely impacted if there are deficiencies in our disclosure controls and procedures or internal control over financial reporting. The
design  and  effectiveness  of  our  disclosure  controls  and  procedures  and  internal  control  over  financial  reporting  may  not  prevent  all  errors,  misstatements  or
misrepresentations.  While  management  will  continue  to  review  the  effectiveness  of  our  disclosure  controls  and  procedures  and  internal  control  over  financial
reporting,  there  can  be  no  guarantee  that  our  internal  control  over  financial  reporting  will  be  effective  in  accomplishing  all  control  objectives  all  of  the  time.
Deficiencies, including any material weakness, in our internal control over financial reporting that may occur in the future could result in misstatements of our
results of operations, restatements of our financial statements, or otherwise adversely impact our financial condition, results of operations, cash flows, the quoted
trading price of our securities, and our ability to satisfy our debt service obligations and to pay dividends and distributions to our security holders.

28

We  face  risks  associated  with  security  breaches  through  cyber  attacks,  cyber  intrusions  or  otherwise,  as  well  as  other  significant  disruptions  of  our
information technology (IT) networks and related systems. We face risks associated with security breaches, whether through cyber attacks or cyber intrusions over
the Internet, malware,  computer viruses, attachments  to e-mails,  persons inside our organization or persons with access to systems inside our organization,  and
other  significant  disruptions  of  our  IT  networks  and  related  systems.  The  risk  of  a  security  breach  or  disruption,  particularly  through  cyber  attack  or  cyber
intrusion,  including  by  computer  hackers,  foreign  governments  and  cyber  terrorists,  has  generally  increased  as  the  number,  intensity  and  sophistication  of
attempted attacks and intrusions from around the world have increased. Our IT networks and related systems are essential to the operation of our business and our
ability to perform day-to-day operations (including managing our building systems), and, in some cases, may be critical to the operations of certain of our tenants.
There can be no assurance that our efforts to maintain the security and integrity of these types of IT networks and related systems will be effective or that attempted
security breaches or disruptions would not be successful or damaging. Like other businesses, we have been and expect to continue to be subject to unauthorized
access,  mishandling  or  misuse,  computer  viruses  or  malware,  cyber  attacks  and  other  events  of  varying  degrees.  Historically,  these  events  have  not  adversely
affected our operations or business and were not individually or in the aggregate material.

However, in the future, events such as these or other significant disruptions involving our IT networks and related systems could, among other things:

•

•

•

•

•

•

•

result  in  unauthorized  access  to,  destruction,  loss,  theft,  misappropriation  or  release  of  proprietary,  confidential,  sensitive  or  otherwise  valuable
information  of  ours  or  others,  including  personally  identifiable  and  account  information  that  could  be  used  to  compete  against  us  or  for  disruptive,
destructive or otherwise harmful purposes and outcomes;

result in unauthorized access to or changes to our financial accounting and reporting systems and related data;

result in the theft of funds;

result in our inability to maintain building systems relied on by our tenants;

require significant management attention and resources to remedy any damage that results;

subject us to regulatory penalties or claims for breach of contract, damages, credits, penalties or terminations of leases or other agreements; or

damage our reputation among our tenants and investors.

These events could have an adverse impact on our financial condition, results of operations, cash flows, the quoted trading price of our securities, and our

ability to satisfy our debt service obligations and to pay dividends and distributions to our security holders.

The  actual  density  of  our  undeveloped  land  holdings  and/or  any  particular  land  parcel  may  not  be  consistent  with  our  potential  density  estimates.  As  of
December 31, 2020, we estimate that our five future development  sites, representing approximately  61 gross acres of undeveloped land, provide more than 6.0
million square feet of potential density. We caution you not to place undue reliance on the potential density estimates for our undeveloped land holdings and/or any
particular land parcel because they are based solely on our estimates, using data currently available to us, and our business plans as of December 31, 2020. The
actual density of our undeveloped land holdings and/or any particular land parcel may differ substantially from our estimates based on numerous factors, including
our inability  to obtain  necessary  zoning, land  use and other required  entitlements,  as well as building,  occupancy and other  required  governmental  permits  and
authorizations, and changes in the entitlement, permitting and authorization processes that restrict or delay our ability to develop, redevelop or use undeveloped
land  holdings  at  anticipated  density  levels.  Moreover,  we  may  strategically  choose  not  to  develop,  redevelop  or  use  our  undeveloped  land  holdings  to  their
maximum potential density or may be unable to do so as a result of factors beyond our control, including our ability to obtain capital on terms that are acceptable to
us, or at all, to fund our development and redevelopment activities. We can provide no assurance that the actual density of our undeveloped

29

land holdings and/or any particular land parcel will be consistent with our potential density estimates. For additional information on our development program, see
“Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations —Factors That May Influence Future Results of Operations.”

Loss of our key personnel could harm our operations and financial performance and adversely affect the quoted trading price of our securities. The leadership
and performance of John Kilroy, the Chairman of our board of directors and our Chief Executive Officer, plays a key role in the success of the Company. He is
integral to the Company’s success for many reasons, including that he has a strong national or regional reputation in our industry and investment community. In
addition, he has significant relationships with investors, lenders, tenants and industry personnel, which benefit the Company.

If workers providing services at our properties were to engage in a strike or other work stoppage or interruption, our business, results of operations, financial
condition and liquidity  could be materially  adversely  affected. Although  we  believe  that  our  relations  with  our  service  providers  are  good,  if  disputes  with  our
service providers arise or if workers providing services at our properties engage in a strike or other work stoppage or interruption, we could experience a significant
disruption of, or inefficiencies in, our operations or at our properties or incur higher labor costs, which could have a material adverse effect on our business, results
of operations, financial condition and liquidity.

Risks Related to Our Indebtedness

We  may  not  be  able  to  meet  our  debt  service  obligations.  As  of  December  31,  2020,  we  had  approximately  $4.0  billion  aggregate  principal  amount  of
indebtedness, of which $5.3 million in principal payments will be paid during the year ended December 31, 2021. Our total debt at December 31, 2020 represented
37.0% of our total market capitalization (which we define as the aggregate of our long-term debt and the market value of the Company’s common stock and the
Operating Partnership’s common units of limited partnership interest, or common units, based on the closing price per share of the Company’s common stock as of
that date). For the calculation of our market capitalization and additional information on debt maturities, see “Item 7. Management’s Discussion and Analysis of
Financial Condition and Results of Operations —Liquidity and Capital Resources of the Company —Capitalization” and “Item 7. Management’s Discussion and
Analysis of Financial Condition and Results of Operations —Liquidity and Capital Resources of the Operating Partnership —Liquidity Uses.”

Our  ability  to  make  payments  on  and  to  refinance  our  indebtedness  and  to  fund  our  operations,  working  capital,  and  capital  expenditures,  depends  on  our
ability  to  generate  cash  flow  in  the  future.  Our  cash  flow  is  subject  to  general  economic,  industry,  financial,  competitive,  operating,  legislative,  regulatory,
environmental and other factors, many of which are beyond our control.

The  instruments  and  agreements  governing  some  of  our  outstanding  indebtedness  (including  borrowings  under  the  Operating  Partnership’s  unsecured
revolving  credit  facility  and  note  purchase  agreements)  contain  provisions  that  require  us  to  repurchase  for  cash  or  repay  that  indebtedness  under  specified
circumstances  or  upon  the  occurrence  of  specified  events  (including  upon  the  acquisition  by  any  person  or  group  of  more  than  a  specified  percentage  of  the
aggregate voting power of all the Company’s issued and outstanding voting stock, upon certain changes in the composition of a majority of the members of the
Company’s board of directors, if the Company or one of its wholly-owned subsidiaries ceases to be the sole general partner of the Operating Partnership or if the
Company ceases to own, directly or indirectly, at least 60% of the voting equity interests in the Operating Partnership), and our future debt agreements and debt
securities may contain similar provisions or may require that we repay or repurchase or offer to repurchase for cash the applicable indebtedness under specified
circumstances or upon the occurrence of specified changes of control of the Company or the Operating Partnership or other events. We may not have sufficient
funds to pay our indebtedness when due (including upon any such required repurchase, repayment or offer to repurchase), and we may not be able to arrange for
the financing necessary to make those payments or repurchases on favorable terms or at all. In addition, our ability to make required payments on our indebtedness
when due (including upon any such required repurchase, repayment or offer to repurchase) may be limited by the terms of other debt instruments or agreements.
Our failure to pay amounts due in respect of any of our indebtedness when due would generally constitute an event of default under the instrument governing that
indebtedness,  which  could  permit  the  holders  of  that  indebtedness  to  require  the  immediate  repayment  of  that  indebtedness  in  full  and,  in  the  case  of  secured
indebtedness, could allow them to sell the collateral securing that

30

indebtedness  and  use  the  proceeds  to  repay  that  indebtedness.  Moreover,  any  acceleration  of  or  default  in  respect  of  any  of  our  indebtedness  could,  in  turn,
constitute an event of default under other debt instruments or agreements, thereby resulting in the acceleration and required repayment of that other indebtedness.
Any of these events could materially adversely affect our ability to make payments of principal and interest on our indebtedness when due and could prevent us
from making those payments altogether.

We cannot assure you that our business will generate sufficient cash flow from operations or that future sources of cash will be available to us in an amount
sufficient  to  enable  us  to  pay  amounts  due  on  our  indebtedness  or  to  fund  our  other  liquidity  needs,  including  cash  distributions  to  stockholders  necessary  to
maintain the Company’s REIT qualification. Additionally, if we incur additional indebtedness in connection with future acquisitions or for any other purpose, our
debt service obligations could increase.

We may need to refinance all or a portion of our indebtedness on or before maturity. Our ability to refinance our indebtedness or obtain additional financing

will depend on, among other things:

•

•

our financial condition, results of operations and market conditions at the time; and

restrictions in the agreements governing our indebtedness.

As a result, we may not be able to refinance our indebtedness on commercially  reasonable terms or at all. If we do not generate sufficient cash flow from
operations, and additional borrowings or refinancings or proceeds of asset sales or other sources of cash are not available to us, we may not have sufficient cash to
enable  us  to  meet  all  of  our  obligations.  Accordingly,  if  we  cannot  service  our  indebtedness,  we  may  have  to  take  actions  such  as  seeking  additional  equity
financing, delaying capital expenditures, or entering into strategic acquisitions and alliances. Any of these events or circumstances could have a material adverse
effect on our financial condition, results of operations, cash flows, the trading price of our securities and our ability to satisfy our debt service obligations and to
pay dividends and distributions to our security holders. In addition, foreclosures could create taxable income without accompanying cash proceeds, which could
require us to borrow or sell assets to raise the funds necessary to pay amounts due on our indebtedness and to meet the REIT distribution requirements discussed
below, even if such actions are not on favorable terms.

The  covenants  in  the  agreements  governing  the  Operating  Partnership’s  unsecured  revolving  credit  facility  and  note  purchase  agreements  may  limit  our
ability to make distributions to the holders of our common stock. The Operating Partnership’s $750.0 million unsecured revolving credit facility and note purchase
agreements contain financial covenants that could limit the amount of distributions payable by us on our common stock and any preferred stock we may issue in
the future. We rely on cash distributions we receive from the Operating Partnership to pay distributions on our common stock and any preferred stock we may
issue in the future and to satisfy our other cash needs. The agreements governing the unsecured revolving credit facility and the note purchase agreements provide
that, if the Operating Partnership fails to pay any principal of, or interest on, any borrowings or other amounts payable under such agreement when due or during
any  other  event  of  default  under  such  revolving  credit  facility  and  the  unsecured  private  placement  notes,  the  Operating  Partnership  may  make  only  those
partnership distributions that result in distributions to us in an amount sufficient to permit us to make distributions 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. Any limitation on our ability to make distributions to our stockholders, whether as a result of these provisions in the unsecured revolving credit facility, the
note purchase agreements or otherwise, could have a material adverse effect on the market value of our common stock.

A  downgrade  in  our  credit  ratings  could  materially  adversely  affect  our  business  and  financial  condition. The  credit  ratings  assigned  to  the  Operating
Partnership’s  debt  securities  and  any  preferred  stock  we  may  issue  in  the  future  could  change  based  upon,  among  other  things,  our  results  of  operations  and
financial  condition.  These  ratings  are  subject  to  ongoing  evaluation  by  credit  rating  agencies,  and  we  cannot  assure  you that  any  rating  will  not  be  changed  or
withdrawn by a rating agency in the future if, in its judgment, circumstances warrant. Moreover, these credit ratings do not apply to our common stock and are not
recommendations to buy, sell or hold our common stock or any other securities. If any of the credit rating agencies that have rated the Operating Partnership’s debt
securities or any preferred stock we may issue in the future downgrades or lowers its credit rating, or if any credit rating

agency indicates that it has placed any such rating on a so-called “watch list” for a possible downgrading or lowering or otherwise indicates that its outlook for that
rating is negative, it could have a material adverse effect on our costs and availability of capital, which could in turn have a material adverse effect on our financial
condition,  results  of  operations,  cash  flows,  the  trading  price  of  our  securities,  and  our  ability  to  satisfy  our  debt  service  obligations  and  to  pay  dividends  and
distributions to our security holders.

An increase in interest rates could increase our interest costs on variable rate debt and new debt and could adversely affect our ability to refinance existing
debt, conduct development, redevelopment and acquisition activity and recycle capital. As of December 31, 2020, we had an unsecured revolving credit facility
bearing interest at a variable rate on any amount drawn and outstanding. There was no amount outstanding on the revolving credit facility at December 31, 2020.
However, we may borrow on the revolving credit facility or incur additional variable rate debt in the future. If interest rates increase, so could our interest costs for
any variable rate debt and for new debt. This increased cost could make the financing of any development, redevelopment and acquisition activity costlier. Rising
interest rates could also limit our ability to refinance existing debt when it matures or cause us to pay higher interest rates upon refinancing and increase interest
expense  on  refinanced  indebtedness.  In  addition,  an  increase  in  interest  rates  could  decrease  the  amount  third  parties  are  willing  to  pay  for  our  assets,  thereby
limiting our ability to recycle capital and our portfolio promptly in response to changes in economic or other conditions.

We manage a portion of our exposure to interest rate risk by accessing debt with staggered maturities, and we may in the future mitigate this risk through the
use  of  derivative  instruments,  including  interest  rate  swap  agreements  or  other  interest  rate  hedging  agreements,  including  swaps,  caps  and  floors.  While  these
agreements are intended to lessen the impact of rising interest rates on us, they also expose us to the risks that counter parties may fail to honor their obligations,
that  we could  incur  significant  costs  associated  with  the  settlement  of  these  agreements,  that  the  amount  of  income  we  earn  from  hedging  transactions  may  be
limited by federal tax provisions governing REITs, that these agreements may cause us to pay higher interest rates on our debt obligations than would otherwise be
the case and that underlying transactions could fail to qualify as highly-effective  cash flow hedges under the accounting guidance. As a result, failure to hedge
effectively against interest rate risk, if we choose to engage in such activities, could adversely affect our financial condition, results of operations, cash flows, the
quoted trading price of our securities, and our ability to satisfy our debt service obligations and to pay dividends and distributions to our security holders.

Risks Related to Our Organizational Structure

Our growth depends on external sources of capital that are outside of our control and the inability to obtain capital on terms that are acceptable to us, or at
all,  could  adversely  affect  our  financial  condition  and  results  of  operations.  The  Company  is  required  under  the  Code  to  distribute  at  least  90%  of  its  taxable
income (subject to certain adjustments and excluding any net capital gain), and the Operating Partnership is required to make distributions to the Company to allow
the  Company  to  satisfy  these  REIT  distribution  requirements.  Because  of  these  distribution  requirements,  the  Operating  Partnership  is  required  to  make
distributions  to  the  Company,  and  we  may  not  be  able  to  fund  future  capital  needs,  including  any  necessary  acquisition  financing,  from  operating  cash  flow.
Consequently, management relies on third-party sources of capital to fund our capital needs. We may not be able to obtain financing on favorable terms or at all.
Any additional debt we incur will increase our leverage. Access to third-party sources of capital depends, in part, on general market conditions and the availability
of credit, the market’s perception of our growth potential, our current and expected future earnings, our cash flows and cash distributions and the quoted trading
price of our securities. If we cannot obtain capital from third-party sources, our financial condition, results of operations, cash flows, the quoted trading price of our
securities, and our ability to satisfy our debt service obligations and to pay dividends and distributions to our security holders may be adversely affected.

Our common limited partners have limited approval rights, which may prevent us from completing a change of control transaction that may be in the best
interests of all our security holders. The Company may not withdraw as the Operating Partnership’s general partner or transfer its general partnership interest in
the Operating Partnership without the approval of the holders of at least 60% of the units representing common partnership interests, including the common units
held by the Company in its capacity as the Operating Partnership’s general partner. In addition, the Company may not engage in a merger, consolidation or other
combination or the sale of substantially all of its assets or such similar transaction, without the approval of the holders of 60% of the common units, including the
common  units  held  by  the  Company  in  its  capacity  as  the  Operating  Partnership’s  general  partner.  The  right  of  our  common  limited  partners  to  vote  on  these
transactions could limit our ability to complete a change of control transaction that might otherwise be in the best interest of all our security holders.

In certain circumstances, our limited partners must approve our dissolution and the disposition of properties contributed by the limited partners. For as long
as limited partners own at least 5% of all of the Operating Partnership’s partnership interests, we must obtain the approval of limited partners holding a majority of
the units representing common limited partnership interests before we may dissolve. As of December 31, 2020, limited partners owned approximately 1.0% of the
Operating Partnership’s partnership interests, of which 0.7% was owned by John Kilroy. In addition, we agreed to use commercially reasonable efforts to minimize
the tax consequences to certain common limited partners resulting from the repayment, refinancing, replacement, or restructuring of debt, or any sale, exchange, or
other disposition of any of our other assets. The exercise of one or more of these approval rights by the limited partners could delay or prevent us from completing
a transaction that may be in the best interest of all our security holders.

The Chairman of our board of directors and Chief Executive Officer has substantial influence over our affairs. John Kilroy is the Chairman of our board of
directors and our Chief Executive Officer. John Kilroy beneficially owned, as of December 31, 2020, approximately 1.4% of the total outstanding shares of our
common  stock.  The  percentage  of  outstanding  shares  of  common  stock  beneficially  owned  includes  330,451  shares  of  common  stock,  515,127  restricted  stock
units  (“RSUs”)  that  were  vested  and  held  by  John  Kilroy  at  December  31,  2020,  and  assumes  the  exchange  into  shares  of  our  common  stock  of  the
783,192 common units of the Operating Partnership held by John Kilroy (which may be exchanged for an equal number of shares of our common stock).

Pursuant to the Company’s charter, no stockholder may own, actually or constructively, more than 7.0% (by value or by number of shares, whichever is more
restrictive) of our outstanding common stock without obtaining a waiver from the board of directors. In connection with the Company’s initial public offering, the
board of directors waived the ownership limits with respect to John Kilroy, members of his family and some of their affiliated entities. These named individuals
and  entities  may  own  either  actually  or  constructively,  in  the  aggregate,  up  to  19.6%  of  our  common  stock,  excluding  Operating  Partnership  units  that  are
exchangeable into shares of our common stock. Consequently, John Kilroy has substantial influence over the Company, and because the Company is the manager
of  the  Operating  Partnership,  over  the  Operating  Partnership,  and  could  exercise  his  influence  in  a  manner  that  is  not  in  the  best  interest  of  our  stockholders,
noteholders or unitholders. Also, John Kilroy may, in the future, have a substantial influence over the outcome of any matters submitted to our stockholders or
unitholders for approval.

There are restrictions on the ownership of the Company’s capital stock that limit the opportunities for a change of control at a premium to existing security
holders. Provisions  of  the  Maryland  General  Corporation  Law,  the  Company’s  charter  and  bylaws  and  the  Operating  Partnership’s  partnership  agreement  may
delay, deter, or prevent a change of control of the Company, or the removal of existing management. Any of these actions might prevent our security holders from
receiving a premium for their shares of common stock or common units over the then-prevailing market price of the shares of our common stock.

In order for the Company to qualify as a REIT under the Code, its stock must be beneficially owned by 100 or more persons during at least 335 days of a
taxable year of 12 months (other than the first year for which an election to be a REIT has been made) or during a proportionate part of a shorter taxable year. Also,
not  more  than  50%  of  the  value  of  the  outstanding  shares  of  the  Company’s  stock  may  be  owned,  actually  or  constructively,  by  five  or  fewer  individuals  (as
defined in the Code to include certain entities) during the last half of a taxable year (other than the first year for which an election to be a REIT has been made).
The Company’s charter contains restrictions on the ownership and transfer of its capital stock that are intended to assist the Company in complying with these
requirements and continuing to qualify as a REIT. No single stockholder may own, either actually or constructively,

33

absent  a  waiver  from  the  board  of  directors,  more  than  7.0%  (by  value  or  by  number  of  shares,  whichever  is  more  restrictive)  of  the  Company’s  outstanding
common stock.

The constructive ownership rules under the Code are complex and may cause stock owned actually or constructively by a group of related individuals and/or
entities to be owned constructively by one individual or entity. As a result, the acquisition of less than the applicable ownership limit of a particular class of the
Company’s capital stock could, nevertheless, cause that individual or entity, or another individual or entity, to constructively own stock in excess of, and thereby
subject such stock to, the applicable ownership limit.

The board of directors may waive the ownership limits if it is satisfied that the excess ownership would not jeopardize the Company’s REIT status and if it
believes that the waiver would be in our best interest. The board of directors has waived the ownership limits with respect to John Kilroy, members of his family
and  some  of  their  affiliated  entities.  These  named  individuals  and  entities  may  own  either  actually  or  constructively,  in  the  aggregate,  up  to  19.6%  of  our
outstanding common stock, excluding common units that are exchangeable into shares of common stock.

If anyone acquires shares in excess of any ownership limits without a waiver, the transfer to the transferee will be void with respect to the excess shares, the
excess shares will be automatically transferred to a trust for the benefit of a qualified charitable organization, and the purported transferee or owner will have no
rights with respect to those excess shares.

The Company’s charter  contains  provisions  that  may  delay,  deter  or prevent  a  change  of  control  transaction.  The following provisions of the Company’s
charter may delay or prevent a change of control over us, even if a change of control might be beneficial to our security holders, deter tender offers that may be
beneficial to our security holders, or limit security holders’ opportunity to receive a potential premium for their shares and/or units if an investor attempted to gain
shares beyond the Company’s ownership limits or otherwise to effect a change of control:

•

•

the  Company’s  charter  authorizes  the  board  of  directors  to  issue  up  to  30,000,000  shares  of  the  Company’s  preferred  stock,  including  convertible
preferred stock, without stockholder approval. The board of directors may establish the preferences, rights and other terms, including the right to vote and
the right to convert into common stock any shares issued. The issuance of preferred stock could delay or prevent a tender offer or a change of control even
if a tender offer or a change of control was in our security holders’ interest; and

the Company’s charter states that any director, or the entire board of directors, may be removed from office at any time, but only for cause and then only
by the affirmative vote of the holders of at least two thirds of the votes of the Company’s capital stock entitled to be cast in the election of directors.

The board of directors may change investment and financing policies without stockholder or unitholder approval. Our board of directors determines our major
policies,  including  policies  and  guidelines  relating  to  our  acquisition,  development  and  redevelopment  activities,  leverage,  financing,  growth,  operations,
indebtedness, capitalization and distributions to our security holders. Our board of directors may amend or revise these and other policies and guidelines from time
to time without stockholder or unitholder approval. Accordingly, our stockholders and unitholders will have limited control over changes in our policies and those
changes could adversely impact our financial condition, results of operations, cash flows, the quoted trading price of our securities, and our ability to satisfy our
debt service obligations and to pay dividends and distributions to our security holders.

We  are  not  limited  in  our  ability  to  incur  debt.  Our  financing  policies  and  objectives  are  determined  by  the  board  of  directors.  Our  goal  is  to  limit  our
dependence on leverage and maintain a conservative ratio of debt to total market capitalization. However, our organizational documents do not limit the amount or
percentage of indebtedness, funded or otherwise, that we may incur. As of December 31, 2020, we had approximately $4.0 billion aggregate principal amount of
indebtedness outstanding, which represented 37.0% of our total market capitalization. See “Item 7. Management’s Discussion and Analysis of Financial Condition
and Results of Operations —Liquidity and Capital Resources of the Company —Capitalization” for a calculation of our market capitalization. These ratios may be
increased or decreased without the consent of our unitholders or stockholders. Increases in the amount of debt outstanding would result in an increase in our debt
service costs, which could adversely affect cash flow and

34

our ability to pay dividends and distributions to our security holders. Higher leverage also increases the risk of default on our obligations and limits our ability to
obtain additional financing in the future.

We may issue additional common units and shares of capital stock without unitholder or stockholder approval, as applicable, which may dilute unitholder or
stockholder  investment.  The  Company  may  issue  shares  of  our  common  stock,  preferred  stock  or  other  equity  or  debt  securities  without  stockholder  approval,
including the issuance of shares to satisfy REIT dividend distribution requirements. Similarly, the Operating Partnership may offer its common or preferred units
for contributions of cash or property without approval by our stockholders or the Operating Partnership’s unitholders. Existing security holders have no preemptive
rights to acquire any of these securities, and any issuance of equity securities under these circumstances may dilute a unitholder's or stockholder's investment.

Sales of a substantial number of shares of the Company’s securities, or the perception that this could occur, could result in decreasing the quoted trading
price per share of the Company’s common stock and of the Operating Partnership’s publicly-traded notes. Management cannot predict whether future issuances of
shares  of  the  Company’s  common  stock,  or  the  availability  of  shares  for  resale  in  the  open  market  will  result  in  decreasing  the  market  price  per  share  of  the
Company’s common stock. As of December 31, 2020, 116,035,827 shares of the Company’s common stock were issued and outstanding.

As of December 31, 2020, the Company had reserved for future issuance the following shares of common stock: 1,150,574 shares issuable upon the exchange,
at the Company’s option, of the Operating Partnership’s common units; approximately 1.5 million shares remained available for grant under our 2006 Incentive
Award  Plan  (see  Note  15  “Share-Based  and  Other  Compensation”  to  our  consolidated  financial  statements  included  in  this  report);  approximately  1.6  million
shares issuable upon settlement of time-based RSUs; a maximum of 1.5 million shares contingently issuable upon settlement of RSUs subject to the achievement
of  market  and/or  performance  conditions;  and  9,000  shares  issuable  upon  exercise  of  outstanding  options.  The  Company  has  a  currently  effective  registration
statement registering 10.7 million shares of our common stock for possible issuance under our 2006 Incentive Award Plan. The Company has a currently effective
registration  statement  registering  1,649,760  shares  of  our  common  stock  for  possible  issuance  to  and  resale  by  certain  holders  of  the  Operating  Partnership’s
common units. That registration statement also registers 94,441 shares of common stock held by John Kilroy for possible resale. Consequently, if and when the
shares are issued, they may be freely traded in the public markets.

Risks Related to Taxes and the Company’s Status as a REIT

Loss of the Company’s REIT status would have significant adverse consequences to us and the value of the Company’s common stock. The Company currently
operates in a manner that is intended to allow it to qualify as a REIT for federal income tax purposes under the Code. If the Company were to lose its REIT status,
the Company would face adverse  tax consequences  that  would substantially  reduce  the funds available  for distribution  to its stockholders  for each of the years
involved because:

•

•

•

the Company would not be allowed a deduction for dividends paid to its stockholders in computing the Company’s taxable income and would be subject
to regular U.S. federal corporate income tax;

the Company could be subject to increased state and local taxes; and

unless entitled to relief under statutory provisions, the Company could not elect to be taxed as a REIT for four taxable years following the year during
which the Company was disqualified.

In addition, if the Company failed to qualify as a REIT, it would not be required to make distributions to its stockholders. As a result of all these factors, the
Company’s failure to qualify as a REIT also could impair our ability to expand our business and raise capital, and could adversely affect the value and quoted
trading price of the Company’s common stock.

Qualification as a REIT involves the application of highly technical and complex Code provisions for which there are only limited judicial and administrative
interpretations. The complexity of these provisions and of the applicable Treasury regulations that have been promulgated under the Code is greater in the case of a
REIT that, like

35

the Company, holds its assets through a partnership. The determination of various factual matters and circumstances not entirely within our control may affect the
Company’s ability to continue to qualify as a REIT. For example, to qualify as a REIT, at least 95% of the Company’s gross income in any year must be derived
from qualifying sources. Also, the Company must make distributions to its stockholders aggregating annually at least 90% of the Company’s net taxable income
(subject to certain adjustments and excluding any net capital gains). In addition, legislation, new regulations, administrative interpretations or court decisions may
adversely affect the Company’s security holders or the Company’s ability to qualify as a REIT for federal income tax purposes or the desirability of an investment
in  a  REIT  relative  to  other  investments.  Although  management  believes  that  we  are  organized  and  operate  in  a  manner  to  permit  the  Company  to  continue  to
qualify as a REIT, we cannot provide assurances that the Company has qualified or will continue to qualify as a REIT for tax purposes. We have not requested and
do not plan to request a ruling from the Internal Revenue Service (“IRS”) regarding the Company’s qualification as a REIT.

To  maintain  the  Company’s  REIT  status,  we  may  be  forced  to  borrow  funds  during  unfavorable  market  conditions.  To  qualify  as  a  REIT,  the  Company
generally must distribute to its stockholders at least 90% of the Company’s net taxable income each year (subject to certain adjustments and excluding any net
capital  gains),  and  the  Company  will  be  subject  to  regular  corporate  income  taxes  to  the  extent  that  it  distributes  less  than  100%  of  its  net  capital  gains  or
distributes at least 90%, but less than 100%, of its net taxable income each year. In addition, the Company will be subject to a 4% nondeductible excise tax on the
amount, if any, by which distributions it pays in any calendar year are less than the sum of 85% of its ordinary income, 95% of its net capital gains, and 100% of its
undistributed  income  from  prior  years.  To  maintain  the  Company’s  REIT  status  and  avoid  the  payment  of  federal  income  and  excise  taxes,  the  Operating
Partnership  may  need  to  borrow  funds  and  distribute  or  loan  the  proceeds  to  the  Company  so  it  can  meet  the  REIT  distribution  requirements  even  if  the  then-
prevailing market conditions are not favorable for these borrowings. These borrowing needs could result from differences in timing between the actual receipt of
income and inclusion of income for federal income tax purposes, or the effect of nondeductible capital expenditures, the creation of reserves or required debt or
amortization payments.

If a transaction intended to qualify as a Section 1031 Exchange is later determined to be taxable or if we are unable to identify and complete the acquisition of
a  suitable  replacement  property  to  effect  a  Section  1031  Exchange,  we  may  face  adverse  consequences,  and  if  the  laws  applicable  to  such  transactions  are
amended or repealed, we may not be able to dispose of properties on a tax deferred basis. When possible, we dispose of properties in transactions that are intended
to  qualify  as  Section  1031  Exchanges.  It  is  possible  that  the  qualification  of  a  transaction  as  a  Section  1031  Exchange  could  be  successfully  challenged  and
determined to be currently taxable or that we may be unable to identify and complete the acquisition of a suitable replacement property to effect a Section 1031
Exchange. In such case, our taxable income and the Company’s and earnings and profits could increase. This could increase the dividend income to the Company’s
stockholders by reducing any return of capital they received. In some circumstances, the Company may be required to pay additional dividends or, in lieu of that,
corporate income tax, possibly including interest and penalties. As a result, we may be required to borrow funds in order to pay additional dividends or taxes and
the payment of such taxes could cause us to have less cash available to distribute to the Company’s stockholders. In addition, if a Section 1031 Exchange were
later to be determined to be taxable, we may be required to amend our tax returns for the applicable year in question, including any information reports we sent the
Company’s stockholders. Moreover, under the Tax Cuts and Jobs Act (the “2017 Tax Legislation”), for exchanges completed after December 31, 2017, unless the
property was disposed of or received in the exchange on or before such date, Section 1031 of the Code permits exchanges of real property only. It is possible that
additional legislation could be enacted that could further modify or repeal the laws with respect to Section 1031 Exchanges, which could make it more difficult or
not possible for us to dispose of properties on a tax deferred basis.

Dividends payable by REITs, including the Company, generally do not qualify for the reduced tax rates available for some dividends. “Qualified dividends”
payable  to  U.S.  stockholders  that  are  individuals,  trusts  and  estates  generally  are  subject  to  tax  at  preferential  rates.  Subject  to  limited  exceptions,  dividends
payable by REITs are not eligible for these reduced rates and are taxable at ordinary income tax rates. The more favorable rates applicable to regular corporate
qualified dividends could cause investors who are individuals, trusts and estates to perceive investments in REITs to be relatively less attractive than investments in
the stocks of non-REIT corporations that pay dividends, which could adversely affect the value of the shares of REITs, including the shares of our capital stock.
However, non-corporate stockholders, including individuals, generally may deduct up to 20%

36

of dividends from a REIT, other than capital gain dividends and dividends treated as qualified dividend income, for taxable years beginning after December 31,
2017 and before January 1, 2026.

The tax imposed on REITs engaging in “prohibited transactions” may limit our ability to engage in transactions which would be treated as sales for federal
income  tax  purposes.  A  REIT’s  net  income  from  prohibited  transactions  is  subject  to  a  100%  penalty  tax.  In  general,  prohibited  transactions  are  sales  or  other
dispositions of property, other than foreclosure property, held primarily for sale to customers in the ordinary course of business. Although we do not intend to hold
any properties that would be characterized as held for sale to customers in the ordinary course of our business, unless a sale or disposition qualifies under certain
statutory safe harbors, such characterization is a factual determination and no guarantee can be given that the IRS would agree with our characterization of our
properties or that we will always be able to make use of the available safe harbors.

Complying with REIT requirements may cause us to forego otherwise attractive opportunities or liquidate otherwise attractive investments. To qualify as a
REIT  for  federal  income  tax  purposes,  the  Company  must  continually  satisfy  tests  concerning,  among  other  things,  the  sources  of  its  income,  the  nature  and
diversification of its assets, the amounts it distributes to its stockholders and the ownership of its capital stock. If the Company fails to comply with one or more of
the asset tests at the end of any calendar quarter, the Company must correct the failure within 30 days after the end of the calendar quarter or qualify for certain
statutory relief provisions to avoid losing its REIT qualification and suffering adverse tax consequences. In order to meet these tests, we may be required to forego
investments we might otherwise make or to liquidate otherwise attractive investments. Thus, compliance with the REIT requirements may hinder our performance
and reduce amounts available for distribution to the Company’s stockholders.

Legislative or regulatory action could adversely affect our stockholders or us. In recent years, numerous legislative, judicial and administrative changes have
been made to the federal income tax laws applicable to investments in REITs and similar entities. Additional changes to tax laws are likely to continue to occur in
the  future,  and  any  such  changes  may  adversely  impact  the  Company’s  ability  to  qualify  as  a  REIT,  its  tax  treatment  as  a  REIT,  our  ability  to  comply  with
contractual obligations or the tax treatment of our stockholders and limited partners. Also, the law relating to the tax treatment of other entities, or an investment in
other entities, could change, making an investment in such other entities more attractive relative to an investment in a REIT.

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 at the historical cost of the property as the projects or phases of projects are placed in service.

During the year ended December 31, 2020, we added four development projects to our stabilized portfolio consisting of 750,370 square feet of office in San
Francisco,  California,  361,388  square  feet  of  office  space  in  Hollywood,  California,  95,871  square  feet  of  retail  space  and  608  residential  units  in  San  Diego,
California.  As  of  December  31,  2020,  the  following  properties  were  excluded  from  our  stabilized  portfolio.  We  did  not  have  any  redevelopment  properties  or

In addition to the estimated office and life science rentable square feet noted above, development projects under construction also include 193 residential units.

Our  stabilized  portfolio  also  excludes  our  future  development  pipeline,  which  as  of  December  31,  2020,  was  comprised  of  five  future  development  sites,

representing approximately 61 gross acres of undeveloped land.

As of December 31, 2020, all of our properties and development projects were owned and all of our business was conducted in the state of California with the
exception of eight stabilized office properties, one development project in the tenant improvement phase and one future development project located in the state of
Washington. All of our properties and development projects are 100% owned, excluding four office properties owned by three consolidated property partnerships.

We  own  our  interests  in  all  of  our  real  estate  assets  through  the  Operating  Partnership.  All  our  properties  are  held  in  fee,  except  for  the  fourteen  office
buildings that are held subject to five long-term ground leases for the land (see Note 18 “Commitments and Contingencies” to our consolidated financial statements
included in this report for additional information regarding our ground lease obligations).

In  general,  the  office  properties  are  leased  to  tenants  on  a  full  service  gross,  modified  gross  or  triple  net  basis.  Under  a  full  service  gross  lease,  we  are
obligated to pay the tenant’s proportionate share of real estate taxes, insurance and operating expenses up to the amount incurred during the tenant’s first year of
occupancy (“Base Year”). The tenant pays its pro-rata share of increases in expenses above the Base Year. A modified gross lease is similar to a full service gross
lease, except tenants are obligated to pay their proportionate share of certain operating expenses, usually electricity, directly to the service provider. In addition,
some office properties, primarily in the Greater Seattle region and certain properties in certain submarkets in the San Francisco Bay Area and Greater Los Angeles,
are leased to tenants on a triple net basis, pursuant to which the tenants pay their proportionate share of real estate taxes, operating costs and utility costs.

We believe that all of our properties are well maintained and do not require significant capital improvements. As of December 31, 2020, we managed all of

NAREIT All Equity REIT Index, the Standard & Poor’s 500 Stock Index, and the SNL US REIT Office Index for the five-year period ended December 31, 2020.

investors about our performance relative to a more specific peer group. The SNL US REIT Office Index is a published and widely recognized index that comprises
23 office equity REITs, including us. The graph assumes the investment of $100 in us and each of the indices on December 31, 2015 and, as required by the SEC,
the reinvestment of all distributions. The return shown on the graph is not necessarily indicative of future performance.

_____________________
(1)    On January 1, 2019, the Company adopted FASB Topic 842 and recorded right of use ground lease assets and ground lease liabilities on its consolidate balance sheets. As of December 31,
2020 and 2019, the consolidated balance sheets included $95.5 million and $96.3 million, respectively, of right of use ground lease assets and $97.8 million and $98.4 million, respectively,
of ground lease liabilities.

(2)        Includes  the  noncontrolling  interests  of  the  common  units  of  the  Operating  Partnership  and  consolidated  property  partnerships  (see  Note  2  “Basis  of  Presentation  and  Significant

Accounting Policies” to our consolidated financial statements included in this report for additional information).

(3)    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.

Adjustments to arrive at FFO were as follows: net income attributable to noncontrolling common units of the Operating Partnership, net income attributable to noncontrolling interests in
consolidated  property  partnerships,  depreciation  and  amortization  of  real  estate  assets,  gains  on  sales  of  depreciable  real  estate  and  FFO  attributable  to  noncontrolling  interests  in
consolidated  property  partnerships.  For  additional  information,  see  “Item  7.  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  —Non-GAAP
Supplemental  Financial  Measure:  Funds  From  Operations”  including  a  reconciliation  of  the  Company’s  GAAP  net  income  available  for  common  stockholders  to  FFO  for  the  periods
presented.

(4)    FFO includes amortization of deferred revenue related to tenant-funded tenant improvements of $22.5 million, $19.2 million, $18.4 million, $16.8 million and $13.2 million for the years

ended December 31, 2020, 2019, 2018, 2017 and 2016, respectively.

(5)    On January 1, 2017, the Company adopted FASB ASU No. 2016-18 which requires that a statement of cash flows explain the change during the period in the total cash, cash equivalents,

and amounts generally described as restricted cash or restricted cash equivalents. As a

53

result, cash flows provided by (used in) investing activities have been adjusted from prior amounts reported to reflect this change for all periods presented.

(6) Represents physical and economic occupancy.
(7) For the year ended December 31, 2016, represents occupancy at December 31, 2016.

ITEM 7.     MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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 7. 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 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 remediations;

the availability of cash for distribution and debt service and exposure to risk of default under debt obligations;

56

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

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 “Item 1A. Risk Factors,” and in our other filings with the 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 securities laws.

Company Overview

We are a self-administered REIT active in premier office and mixed-use submarkets along the West Coast. We own, develop, acquire and manage real estate
assets,  consisting  primarily  of  Class  A  properties  in  the  coastal  regions  of  Greater  Los  Angeles,  San  Diego  County,  the  San  Francisco  Bay  Area  and  Greater
Seattle,  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%  and  98.1%  general
partnership interest in the Operating Partnership as of December 31, 2020 and 2019, respectively. All of our properties are held in fee except for the fourteen office
buildings that are held subject to long-term ground leases for the land (see Note 18 “Commitments and Contingencies” to our consolidated financial statements
included in this report for additional information regarding our ground lease obligations).

2020 Operating and Development Highlights

We entered 2020 in a very strong financial position and drew on our strengths to manage through the pandemic. We achieved a record year in development by
completing construction on $1.2 billion in projects that were turned over to our tenants for the construction of tenant improvements and 371 residential units and
continued to create value that we believe will drive future earnings and dividend growth.

Development. We continued to execute on our development program during 2020. We added four completed development projects to our stabilized portfolio
totaling 1.2 million rentable square feet of office and retail space and 608 residential units, had three development projects progress from the under construction
phase  to  the  tenant  improvement  phase  and  commenced  revenue  recognition  on  two  development  projects  currently  in  the  tenant  improvement  phase.  See  “—
Factors that May Influence Future Operations” for additional information regarding our development program.

Capital Recycling Program. We have continued to utilize our capital recycling program to provide additional capital to finance development expenditures,
fund potential acquisitions, repay long-term debt and for other general corporate purposes. Our general strategy, depending on market conditions, is to target the
disposition of non-core properties or those that have limited upside for us and redeploy the capital into acquisitions and/or development projects where we can
create  additional  value  to  generate  higher  returns  (see  “—Factors  that  May  Influence  Future  Operations”  for  additional  information).  In  connection  with  this
strategy, during 2020, we generated gross sales proceeds of approximately $75.9 million through the sale of one office building.

Leasing. During 2020, we executed new and renewal leases totaling 0.7 million square feet within our stabilized portfolio with an increase in GAAP rents of

36.5% and an increase in cash rents of 18.4%. Our stabilized office portfolio was 91.2% occupied and 94.3% leased as of December 31, 2020.

2020 Financing Highlights

In 2020, we raised approximately $775.0 million in new debt at a weighted average interest rate of 3.30%, settled all 2019 forward equity sale agreements by
issuing 3,147,110 shares of common stock for net proceeds of $247.3 million and entered into and settled forward equity sale agreements in connection with an

COVID-19 Response

In accordance with local and state government guidance and social distancing recommendations, the majority of our employees have worked remotely since
March 2020. Our robust technology infrastructure was capable of supporting this model. We implemented rigorous protocols for remote work across the Company,
including increased frequency of team update calls and frequent communication across leadership and working levels. We are leveraging technology to ensure our
teams stay connected and productive, and that our culture remains strong even in these unusual circumstances.

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 engaged a 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 where local ordinances and restrictions allow. We have been in communication with tenants
regarding return to work protocols and safety measures, which meet or exceed best practices from state and local guidelines.

We have implemented a rent relief program for the majority of our retail tenants whereby we deferred rent since April 2020 in exchange for an extension of
their current lease term for an equivalent number of months at future rental rates. We expect that we will continue to offer rent relief to the majority of our retail
tenants, given that most cannot resume full operations in certain of our markets where strong state and local government restrictions remain or were put back into
effect, although the form of relief offered may vary in the future. We did not create such a program for our office tenants. We evaluate office rent relief requests on
a specific case by case basis and only consider those which have a justifiable financial basis. Our top 15 tenants represent 49.1% of our total annualized base rental
revenues  and  as  of  December  31,  2020,  we  had  collected  100%  of  the  rent  due  from  our  top  15  tenants  since  the  beginning  of  the  COVID-19  pandemic.  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 which 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.

The  following  table  sets  forth  information  regarding  the  percent  of  contractual  base  rent  and  common  area  maintenance  (“CAM”)  billings  (“gross  rent

billings”) billed, collected, forgiven, and deferred for the three months ended December 31, 2020:

(7) Remaining amounts deferred under repayment plans and through lease term extensions as a percentage of gross rent billings.
(8) Uncollected gross rent billings that have not been forgiven and are not subject to deferral arrangements as a percentage of gross rent billings. Such amounts are subject to the Company’s collectability assessments.

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 for the periods above and rent relief requests to-date may not be indicative of collections,
concessions or requests in future periods.

As of February 1, 2021, across all property types, we had collected approximately 95% of our January 2021 gross rent billings, including 100% from all of our
top  15  tenants.  Excluding  rent  relief  provided  to  certain  tenants,  across  all  property  types,  we  collected  96%  of  our  January  2021  gross  rent  billings.  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. Refer to “Part I, Item IA. Risk Factors”
included in this report  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.

Critical Accounting Policies

The preparation of financial statements in conformity with GAAP requires us to make estimates, assumptions, and judgments that affect the reported amounts
of assets, liabilities, and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses
for the reporting periods.

Certain accounting policies are considered to be critical accounting policies. Critical accounting policies are those policies that require our management team
to make significant estimates and/or assumptions about matters that are uncertain at the time the estimates and/or assumptions are made or where we are required
to make significant judgments and assumptions with respect to the practical application of accounting principles in our business operations. Critical accounting
policies are by definition those policies that are material to our financial statements and for which the impact of changes in estimates, assumptions, and judgments
could have a material impact to our financial statements.

The  following  critical  accounting  policies  discussion  reflects  what  we  believe  are  the  most  significant  estimates,  assumptions,  and  judgments  used  in  the
preparation of our consolidated financial statements. This discussion of our critical accounting policies is intended to supplement the description of our accounting
policies  in  the  footnotes  to  our  consolidated  financial  statements  and  to  provide  additional  insight  into  the  information  used  by  management  when  evaluating
significant estimates, assumptions, and judgments. For further discussion of our significant accounting policies, see Note 2 “Basis of Presentation and Significant
Accounting Policies” to our consolidated financial statements included in this report.

Revenue Recognition

Rental  revenue  for  office  and  retail  operating  properties  is  our  principal  source  of  revenue.  We  recognize  revenue  from  base  rent,  additional  rent  (which
consists of amounts due from tenants for common area maintenance, real estate taxes and other recoverable costs), parking and other lease-related revenue once all
of the following criteria are met: (i) the agreement has been fully executed and delivered, (ii) services have been rendered, (iii) the amount is fixed or determinable
and  (iv)  payment  has  been  received  or  the  collectability  of  the  amount  due  is  probable.  Lease  termination  fees  are  amortized  over  the  remaining  lease  term,  if
applicable. If there is no remaining lease term, they are recognized when received and realized. Minimum annual rental revenues are recognized in rental revenues
on a straight-line basis over the non-cancellable term of the related lease.

Base Rent

The timing of when we commence rental revenue recognition for office, life science and retail properties depends largely on our conclusion as to whether we
are  or  the  tenant  is  the  owner  for  accounting  purposes  of  tenant  improvements  at  the  leased  property.  When  we  conclude  that  we  are  the  owner  of  tenant
improvements for accounting purposes, we record the cost to construct the tenant improvements as an asset and commence rental revenue recognition when the
tenant takes possession of or controls the finished space, which is generally when tenant improvements being recorded as our assets are substantially complete. In
certain instances, when we conclude that the tenant is the owner of certain tenant improvements for accounting purposes, rental revenue recognition begins when
the tenant takes possession or controls the physical use of the leased space, which may occur in phases or for an entire building or project. The determination of
who owns the tenant improvements is made on a lease-by-lease basis and has a significant effect on the timing of commencement of revenue recognition.

The determination of whether we are or the tenant is the owner of tenant improvements for accounting purposes is subject to significant judgment. In making
that  determination,  we  consider  numerous  factors  and  perform  a  detailed  evaluation  of  each  individual  lease.  No  one  factor  is  determinative  in  reaching  a
conclusion. The factors we evaluate include but are not limited to the following:

•

whether  the  lease  agreement  requires  landlord  approval  of  how  the  tenant  improvement  allowance  is  spent  prior  to  installation  of  the  tenant
improvements;

61

•

•

•

•

whether the lease agreement requires the tenant to provide evidence to the landlord supporting the cost and what the tenant improvement allowance was
spent on prior to payment by the landlord for such tenant improvements;

whether the tenant improvements are unique to the tenant or reusable by other tenants;

whether the tenant is permitted to alter or remove the tenant improvements without the consent of the landlord or without compensating the landlord for
any lost utility or diminution in fair value; and

whether the ownership of the tenant improvements remains with the landlord or remains with the tenant at the end of the lease term.

When we conclude that we are the owner of tenant improvements for accounting purposes using the factors discussed above, we record the cost to construct
the tenant improvements, including costs paid for or reimbursed by the tenants, as our capital asset. During the years ended December 31, 2020, 2019, and 2018,
we  capitalized  $15.5  million,  $12.0  million,  and  $22.5  million,  respectively,  of  tenant-funded  tenant  improvements.  The  amount  of  tenant-funded  tenant
improvements recorded in any given year varies based upon the mix of specific leases executed and/or commenced during the reporting period. For these tenant-
funded tenant improvements, we record the amount funded by or reimbursed by tenants as deferred revenue, which is amortized and recognized as rental income
on a straight-line basis over the term of the related lease beginning upon substantial completion of the leased premises. The determination of who owns the tenant
improvements has a significant impact on the amount of non-cash rental revenue that we record related to the amortization of deferred revenue for tenant-funded
tenant improvements. For the years ended December 31, 2020, 2019, and 2018, we recognized $22.5 million, $19.2 million and $18.4 million, respectively, of non-
cash rental revenue related to the amortization of deferred revenue recorded in connection with tenant-funded tenant improvements.

When  we  conclude  that  the  tenant  is  the  owner  of  certain  tenant  improvements  for  accounting  purposes,  we  record  our  contribution  towards  those  tenant-
owned improvements as a lease incentive, which is included in deferred leasing costs and acquisition-related intangible assets, net on our consolidated balance
sheets and amortized as a reduction to rental revenue on a straight-line basis over the term of the related lease.

For residential properties, we commence revenue recognition upon lease commencement. Residential rental revenue is recognized on a straight-line basis over

the term of the related lease, net of any concessions.

Additional Rent - Reimbursements from Tenants

Additional rent, consisting of amounts due from tenants for common area maintenance, real estate taxes, and other recoverable costs, are recognized in rental
income in the period the recoverable costs are incurred. Prior to the adoption of Financial Accounting Standards Board (“FASB”) Accounting Standards Update
(“ASU”) No. 2016-02 “Leases (Topic 842)” (“Topic 842”) on January 1, 2019, such amounts were recognized in revenue as tenant reimbursements. Additional
rent where we pay the associated costs directly to third-party vendors and are reimbursed by our tenants are recognized and recorded on a gross basis, with the
corresponding expense recognized in property expenses or real estate taxes. Prior to the adoption of Topic 842, recoverable costs were generally recognized and
recorded on a gross basis when we were the primary obligor with respect to purchasing goods and services from third-party suppliers, had discretion in selecting
the supplier, and had credit risk.

Calculating  additional  rent  requires  an  in-depth  analysis  of  the  complex  terms  of  each  underlying  lease.  Examples  of  judgments  and  estimates  used  when

determining the amounts recoverable include:

•

•

estimating the final expenses, net of accruals, that are recoverable;

estimating the fixed and variable components of operating expenses for each building;

62

•

•

conforming recoverable expense pools to those used in establishing the base year or base allowance for the applicable underlying lease; and

concluding whether an expense or capital expenditure is recoverable pursuant to the terms of the underlying lease.

During the year, we accrue estimated additional rent in the period in which the recoverable costs are incurred based on our best estimate of the amounts to be
recovered. Throughout the year, we perform analyses to properly match additional rent with reimbursable costs incurred to date. Additionally, during the fourth
quarter  of  each  year,  we  perform  preliminary  reconciliations  and  accrue  additional  rent  or  refunds.  Subsequent  to  year  end,  we  perform  final  detailed
reconciliations and analyses on a lease-by-lease basis and bill or refund each tenant for any cumulative annual adjustments in the first and second quarters of each
year for the previous year’s activity. Our historical experience for the years ended December 31, 2019 and 2018 has been that our final reconciliation and billing
process resulted in final amounts that approximated the total annual additional rent recognized.

Uncollectible Lease Receivables and Allowances for Tenant and Deferred Rent Receivables

We carry our current and deferred rent receivables net of allowances for amounts that may not be collected. Prior to the adoption of Topic 842 on January 1,
2019, the allowances were increased or decreased through provision for bad debts on our consolidated statements of operations. Upon the adoption of Topic 842 on
January 1, 2019, the allowances are increased or decreased through rental income, and our determination of the adequacy of the Company’s allowances for tenant
receivables includes a binary assessment of whether or not substantially all of the amounts due under a tenant’s lease agreement are probable of collection. Such
assessment involves using a methodology that incorporates a specific identification analysis and an aging analysis and considers the current economic and business
environment.  This  determination  requires  significant  judgment  and  estimates  about  matters  that  are  uncertain  at  the  time  the  estimates  are  made,  including  the
creditworthiness  of  specific  tenants,  specific  industry  trends  and  conditions,  and  general  economic  trends  and  conditions.  Since  these  factors  are  beyond  our
control, actual results can differ from our estimates, and such differences could be material. 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
which would be recognized on a straight-line basis or (ii) cash that has been received from the tenant, including deferred revenue, 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.

For  tenant  and  deferred  rent  receivables  associated  with  leases  whose  rents  are  deemed  probable  of  collection,  we  may  record  an  allowance  under  other
authoritative GAAP using a methodology that incorporates a specific identification analysis and an aging analysis and considers the current economic and business
environment.  This  determination  requires  significant  judgment  and  estimates  about  matters  that  are  uncertain  at  the  time  the  estimates  are  made,  including  the
creditworthiness  of  specific  tenants,  specific  industry  trends  and  conditions,  and  general  economic  trends  and  conditions.  Since  these  factors  are  beyond  our
control, actual results can differ from our estimates, and such differences could be material. Tenant and deferred rent receivables deemed probable of collection are
carried net of allowances for uncollectible accounts, with increases or decreases in the allowances recorded through rental income on our consolidated statements
of  operations.  Prior  to  the  adoption  of  Topic  842  on  January  1,  2019,  the  allowances  were  increased  or  decreased  through  provision  for  bad  debts  on  our
consolidated statements of operations.

Current  tenant  receivables  consist  primarily  of  amounts  due  for  contractual  lease  payments  and  reimbursements  of  common  area  maintenance  expenses,
property taxes, and other costs recoverable from tenants. With respect to the allowance for uncollectible tenant receivables, the specific identification methodology
analysis relies on factors such as the age and nature of the receivables, the payment history and financial condition of the tenant, our assessment of the tenant’s
ability to meet its lease obligations, and the status of negotiations of any disputes with the tenant.

Deferred rent receivables represent the amount by which the cumulative straight-line rental revenue recorded to date exceeds cash rents billed to date under the

lease agreement. With respect to the allowance for deferred rent

63

receivables, given the longer-term nature of these receivables, the specific identification methodology analysis evaluates each of our significant tenants and any
tenants on our internal watchlist and relies on factors such as each tenant’s financial condition and its ability to meet its lease obligations. We evaluate our reserve
levels quarterly based on changes in the financial condition of tenants and our assessment of the tenant’s ability to meet its lease obligations, overall economic
conditions, and the current business environment.

For the year ended December 31, 2020, we recorded a net reduction to rental revenues for direct write-offs associated with transitioning certain tenants to a
cash basis of reporting and an allowance for uncollectible accounts for both current tenant receivables and deferred rent receivables of approximately 2.1% of total
revenues. These amounts were primarily as a result of tenant creditworthiness considerations arising from the COVID-19 pandemic, and a portion may potentially
be restored in future periods as circumstances warrant consistent with our accounting policies. For the year ended December 31, 2019, we recorded an increase to
rental revenues for recoveries of prior year provision for bad debts, net of an allowance for uncollectible accounts for both current tenant receivables and deferred
rent receivables, of approximately 0.3% of revenues. For the year ended December 31, 2018, we recorded a total allowance for uncollectible accounts for both
current tenant receivables and deferred rent receivables of approximately 0.4% of total revenues. In the event our estimates were not accurate and we had to change
our allowances by 1% of revenue from continuing operations, the potential impact to our net income available to common stockholders would be approximately
$9.0 million, $8.4 million and $7.5 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Acquisitions

Acquisitions of operating properties and development and redevelopment opportunities generally do not meet the definition of a business and are accounted
for  as  asset  acquisitions,  as  substantially  all  of  the  fair  value  of  the  gross  assets  acquired  is  concentrated  in  a  single  identifiable  asset  or  a  group  of  similar
identifiable assets. For these asset acquisitions, we record the acquired tangible and intangible assets and assumed liabilities based on each asset’s and liability’s
relative fair value at the acquisition date of the total purchase price plus any capitalized acquisition costs.

We assess and consider fair value based on estimated cash flow projections that utilize available market information and discount and/or capitalization rates
that we deem appropriate. Estimates of future cash flows are based on a number of factors including historical operating results, known and anticipated trends, and
market and economic conditions. The acquired assets and assumed liabilities for an operating property acquisition generally include but are not limited to: land and
improvements, buildings and improvements, construction in progress and identified tangible and intangible assets and liabilities associated with in-place leases,
including  tenant  improvements,  leasing  costs,  value  of  above-market  and  below-market  operating  leases  and  ground  leases,  acquired  in-place  lease  values  and
tenant relationships, if any.

The fair value of land and improvements is derived from comparable sales of land and improvements within the same submarket and/or region. The fair value
of buildings and improvements, tenant improvements and leasing costs considers the value of the property as if it was vacant as well as current replacement costs
and other relevant market rate information.

       The  fair  value  of  the  above-market  or  below-market  component  of  an  acquired  in-place  operating  lease  is  based  upon  the  present  value  (calculated  using  a
market  discount  rate)  of  the  difference  between  (i)  the  contractual  rents  to  be  paid  pursuant  to  the  lease  over  its  remaining  non-cancellable  lease  term  and
(ii) management’s estimate of the rents that would be paid using fair market rental rates and rent escalations at the date of acquisition measured over the remaining
non-cancellable  term  of  the  lease  for  above-market  operating  leases  and  the  initial  non-cancellable  term  plus  the  term  of  any  below-market  fixed  rate  renewal
options,  if  applicable,  for  below-market  operating  leases.  The  amounts  recorded  for  above-market  operating  leases  are  included  in  deferred  leasing  costs  and
acquisition-related intangible assets, net on the balance sheet and are amortized on a straight-line basis as a reduction of rental income over the remaining term of
the  applicable  leases.  The  amounts  recorded  for  below-market  operating  leases  are  included  in  deferred  revenue  and  acquisition-related  liabilities,  net  on  the
balance sheet and are amortized on a straight-line basis as an increase to rental income over the remaining term of the applicable leases plus the term of any below-
market fixed rate renewal options, if applicable. Our below-market operating leases generally do not include fixed rate or below-market renewal options. If a lease
were to be terminated or if termination were

64

determined to be likely prior to its contractual expiration (for example resulting from bankruptcy), amortization of the related above-market or below-market lease
intangible would be accelerated.

The fair value of acquired in-place leases is derived based on management’s assessment of lost revenue and costs incurred for the period required to lease the
“assumed vacant” property to the occupancy level when purchased. This fair value is based on a variety of considerations including, but not necessarily limited to:
(1) the value associated with avoiding the cost of originating the acquired in-place leases; (2) the value associated with lost revenue related to tenant reimbursable
operating costs estimated to be incurred during the assumed lease-up period; and (3) the value associated with lost rental revenue from existing leases during the
assumed lease-up period. Factors we consider in performing these analyses include an estimate of the carrying costs during the expected lease-up periods, current
market  conditions,  and  costs  to  execute  similar  leases.  In  estimating  carrying  costs,  we  include  real  estate  taxes,  insurance  and  other  operating  expenses,  and
estimates of lost rental revenue during the expected lease-up periods based on current market demand at market rates. In estimating costs to execute similar leases,
we  consider  leasing  commissions,  legal  and  other  related  expenses.  The  amount  recorded  for  acquired  in-place  leases  is  included  in  deferred  leasing  costs  and
acquisition-related intangible assets, net on the balance sheet and amortized as an increase to depreciation and amortization expense over the remaining term of the
applicable  leases.  If a lease  were to be terminated  or if termination  were determined  to be likely  prior  to its contractual  expiration  (for  example  resulting  from
bankruptcy), amortization of the related unamortized in-place lease intangible would be accelerated.

The determination  of the fair  value  of any  debt  assumed  in  connection  with a  property  acquisition  is  estimated  by discounting  the future  cash  flows using

interest rates available for the issuance of debt with similar terms and remaining maturities.

The  determination  of  the  fair  value  of  the  acquired  tangible  and  intangible  assets  and  assumed  liabilities  of  acquisitions  requires  us  to  make  significant
judgments and assumptions about the numerous inputs discussed above. The use of different assumptions in these fair value calculations could significantly affect
the reported amounts of the allocation of our acquisition related assets and liabilities and the related depreciation and amortization expense recorded for such assets
and liabilities. In addition, because the value of above and below market leases are amortized as either a reduction or increase to rental income, respectively, our
judgments for these intangibles could have a significant impact on our reported rental revenues and results of operations.

Transaction costs associated with our acquisitions, including costs incurred during negotiation, are capitalized as part of the purchase price of the acquisition.

During the years ended December 31, 2020, 2019 and 2018, we capitalized $0.3 million, $1.6 million, and $3.8 million, respectively, of acquisition costs.

Evaluation of Asset Impairment

We evaluate our real estate assets for potential impairment whenever events or changes in circumstances indicate that the carrying amount of a given asset
may not be recoverable. We evaluate our real estate assets for impairment on a property-by-property basis. Indicators we use to determine whether an impairment
evaluation is necessary include:

•

•

•

low occupancy levels, forecasted low occupancy levels or near term lease expirations at a specific property;

deterioration of a given rental submarket as evidenced by significant increases in market vacancy and/or negative absorption rates or continuous increases
in market vacancy and/or negative absorption rates over numerous quarters, which could signal a decrease in future cash flow for properties within that
submarket;

•

•

•

•

significant increases in property sales yields, continuous increases in property sales yields over several quarters, or recent property sales at a loss within a
given submarket, each of which could signal a decrease in the market value of properties;

significant  change  in  strategy  or  use  of  a  specific  property  or  any  other  event  that  could  result  in  a  decreased  holding  period,  including  classifying  a
property as held for sale, or significant development delay;

evidence of material physical damage to the property; and

default by a significant tenant when any of the other indicators above are present.

When we evaluate for potential impairment our real estate assets to be held and used, we first evaluate whether there are any indicators of impairment. If any
impairment indicators are present for a specific real estate asset, we then perform an undiscounted cash flow analysis and compare the net carrying amount of the
real estate asset to the real estate asset’s estimated undiscounted future cash flow over the anticipated holding period. If the estimated undiscounted future cash
flow is less than the net carrying amount of the real estate asset, we perform an impairment loss calculation to determine if the fair value of the real estate asset is
less than the net carrying value of the real estate asset. Our impairment loss calculation compares the net carrying amount of the real estate asset to the real estate
asset’s estimated fair value, which may be based on estimated discounted future cash flow calculations or third-party valuations or appraisals. We recognize an
impairment loss if the amount of the asset’s net carrying amount exceeds the asset’s estimated fair value. If we recognize an impairment loss, the estimated fair
value of the asset becomes its new cost basis. For a depreciable long-lived asset, the new cost basis would be depreciated (amortized) over the remaining useful life
of that asset. If a real estate asset is designated as real estate held for sale, it is carried at the lower of the net carrying value or estimated fair value less costs to sell,
and depreciation ceases.

Our undiscounted cash flow and fair value calculations contain uncertainties because they require management to make assumptions and to apply judgment to
estimate future cash flow and property fair values, including determining our estimated holding period and selecting the discount or capitalization rate that reflects
the risk inherent in future cash flow. Estimating projected cash flow is highly subjective as it requires assumptions related to future rental rates, tenant allowances,
operating  expenditures,  property  taxes,  capital  improvements,  and  occupancy  levels.  We  are  also  required  to  make  a  number  of  assumptions  relating  to  future
economic and market events and prospective operating trends. Determining the appropriate capitalization rate also requires significant judgment and is typically
based on many factors including the prevailing rate for the market or submarket, as well as the quality and location of the properties. Further, capitalization rates
can fluctuate resulting from a variety of factors in the overall economy or within regional markets. If the actual net cash flow or actual market capitalization rates
significantly differ from our estimates, the impairment evaluation for an individual asset could be materially affected.

For  each  property  where  such  an  indicator  occurred  and/or  for  properties  within  a  given  submarket  where  such  an  indicator  occurred,  we  completed  an
impairment evaluation. After completing this process, we determined that for each of the operating properties evaluated, undiscounted cash flows over the holding
period were in excess of carrying value and, therefore, we did not record any impairment losses for these properties for the years ended December 31, 2020, 2019
and 2018.

Cost Capitalization and Depreciation

We  capitalize  costs  associated  with  development  and  redevelopment  activities,  capital  improvements,  and  tenant  improvements,  including  internal
compensation  costs.  For  the  years  ended  December  31,  2020,  2019  and  2018,  we  capitalized  $21.8  million,  $25.6  million  and  $24.2  million,  respectively,  of
internal  costs  to  our  qualifying  development  projects.  In  addition,  for  development  and  redevelopment  projects,  we  also  capitalize  the  following  costs  during
periods in which activities necessary to prepare the project for its intended use are in progress: interest costs based on the weighted average interest rate of our
outstanding indebtedness for the period, real estate taxes and insurance.

66

Amounts capitalized are depreciated or amortized over estimated useful lives determined by management. We depreciate buildings and improvements based
on the estimated useful life of the asset, and we amortize tenant improvements over the shorter of the estimated useful life or estimated remaining life of the related
lease. All capitalized costs are depreciated or amortized using the straight-line method.

Determining  whether  expenditures  meet  the  criteria  for  capitalization  and  the  assignment  of  depreciable  lives  requires  management  to  exercise  significant

judgment. Expenditures that meet one or more of the following criteria generally qualify for capitalization:

•

•

•

provide benefit in future periods;

extend the useful life of the asset beyond our original estimates; and

increase the quality of the asset beyond our original estimates.

Our historical experience has demonstrated that we have not had material write-offs of assets and that our depreciation and amortization estimates have been

reasonable and appropriate.

Share-Based Incentive Compensation Accounting

At December  31, 2020, the Company had one share-based  incentive  compensation  plan, the  Kilroy Realty  2006 Incentive  Award Plan, which is described
more  fully  in  Note  15  “Share-Based  and  Other  Compensation”  to  our  consolidated  financial  statements  included  in  this  report.  The  Executive  Compensation
Committee  determines  compensation  for  executive  officers,  as  defined  in  Rule  16  under  the  Exchange  Act.  Compensation  cost  for  all  share-based  awards,
including options, requires an estimate of fair value on the grant date and compensation cost is recognized on a straight-line basis over the service vesting period,
which represents the requisite service period. The grant date fair value for compensation programs that contain market conditions, like modifiers based on total
stockholder return (a “market condition”), are performed using complex pricing valuation models that require the input of assumptions, including judgments to
estimate expected stock price volatility, expected life, and forfeiture rate. Specifically, the grant date fair value of share-based compensation programs that include
market conditions are calculated using a Monte Carlo simulation pricing model and the grant date fair value of stock option grants are calculated using the Black-
Scholes  valuation  model.  Additionally,  certain  of  our  market  condition  share-based  compensation  programs  also  contain  pre-defined  financial  performance
conditions,  including  FFO  per  share  and  debt  to  EBITDA  ratio  goals  which  can  impact  the  number  of  restricted  stock  units  ultimately  earned.  This  variability
relating to the level of the performance condition achieved requires management’s judgment and estimates, which impacts compensation cost recognized for these
awards  during  the  performance  period.  As  of  December  31,  2020,  the  performance  condition  for  certain  of  our  outstanding  market  condition  share-based
compensation programs has been met and compensation cost for these awards is no longer variable. For these awards, although the number of restricted stock units
ultimately earned remains variable subject to the ultimate achievement level of the market condition, compensation cost is no longer variable for these awards as
the market condition was already taken into consideration as part of the grant date fair value calculation. As of December 31, 2020, there are certain outstanding
share-based compensation awards where the performance conditions have not all yet been met. For these awards, compensation cost and the number of restricted
stock units ultimately earned remains variable and compensation cost for these awards is recorded based the estimated level of achievement of the performance
conditions through the requisite service period. Changes to compensation cost resulting from changes in the estimated level of achievement of the performance
conditions are recorded as cumulative adjustments in the period the change in the estimated level of achievement of the performance conditions is determined.

For  the  years  ended  December  31,  2020,  2019,  and  2018  we  recorded  approximately  $23.4  million,  $18.1  million,  and  $23.5  million,  respectively,  of
compensation cost related to programs that were subject to such valuation models. If the valuation of the grant date fair value for such programs changed by 10%,
the potential impact to our net income available to common stockholders would be approximately $2.0 million, $1.6 million, and $2.0 million for the years ended
December 31, 2020, 2019, and 2018, respectively.

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.

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.

The global impact of the COVID-19 pandemic continues to evolve rapidly and, as cases of the illness caused by the virus have continued to be identified in
additional countries, many countries, including the United States, have reacted by instituting quarantines and restrictions on travel. In addition, both states where
we  own  properties  and/or  have  development  projects  (i.e.,  California  and  Washington),  have  reacted  to  the  COVID-19  pandemic  by  instituting  quarantines,
restrictions on travel, “shelter in place” rules, density limitations, social distancing measures, restrictions on types of business that may continue to operate and/or
restrictions  on  types  of  construction  projects  that  may  continue,  although,  in  certain  cases,  exceptions  are  available  for  essential  retail,  research  and  laboratory
activities,  essential  building  services,  such  as  cleaning  and  maintenance,  and  certain  essential  construction  projects.  Our  development  portfolio  was  largely
unaffected  during  the  year  ended  December  31,  2020;  however,  the  COVID-19  pandemic,  and  restrictions  intended  to  prevent  its  spread,  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” included in this report 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 year ended December 31, 2020, we added the following projects to our stabilized portfolio:

•

•

•

The  Exchange  on  16th,  Mission  Bay,  San  Francisco,  California.  We  commenced  construction  on  this  project  in  June  2015.  This  project  totals
approximately  750,370  gross  rentable  square  feet  consisting  of  738,081  square  feet  of  office  space  and  12,289  square  feet  of  retail  space  at  a  total
estimated  investment  of $585.0 million. The  office  space  in  the  project  is  100%  leased  to  Dropbox,  Inc. We completed  construction  and commenced
revenue recognition on the first two phases comprising approximately 82% of the project in 2019 and on the final phase of the project during the three
months ended March 31, 2020.

One Paseo (Retail) - Del Mar, San Diego, California. We commenced construction on the retail component of this mixed-use project in December 2016,
which is comprised of approximately 95,871 square feet of retail space with a total estimated investment of $100.0 million. At December 31, 2020, the
retail space of the project was 100% leased and 92% occupied.

Netflix  //  On  Vine,  Hollywood,  California.  We  commenced  construction  on  the  office  component  of  this  mixed-use  project  in  January  2018,  which
includes the project’s overall infrastructure and site work and approximately 361,388 square feet of office space for a total estimated investment of $300.0
million. The

68

office space of this project is 100% leased to Netflix, Inc. We completed construction and commenced revenue recognition on the entirety of this project
in the fourth quarter of 2020.

•

One Paseo - Residential (Phases I, II, and III) - Del Mar, San Diego, California. We commenced construction on the residential component of this mixed-
use project in December 2016. Phases I, II, and III are comprised of 237, 225 and 146 residential units, respectively. We completed Phase I during the
third quarter of 2019, Phase II during the first quarter of 2020, and Phase III during the third quarter of 2020. The total estimated investment for all three
phases of the residential component of the project is approximately $390.0 million. As of February 1, 2021, 78% of the Phase I units were leased, 52% of
the Phase II units were leased, and 50% of the Phase III units were leased.

In-Process Development Projects - Tenant Improvement

As of December 31, 2020, 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)  - Del Mar, San Diego, California.  We commenced  construction  on the office  component  of this project  in December  2018, which
encompasses 285,000 square feet of office space at a total estimated investment of $205.0 million. At December 31, 2020, the office component of the
project was 93% leased. We completed construction in June 2020 and as of December 31, 2020, we have commenced revenue recognition on 188,880
square feet, representing approximately 66% of the project. We currently expect the project to reach stabilization in the third quarter of 2021.

9455 Towne Centre  Drive, University  Towne Center,  San Diego, California.  In  March  2019, we commenced  construction  on this  project  which  totals
approximately 160,000 square feet of office space at a total estimated investment of $105.0 million. The project is 100% leased to a Fortune 50 publicly
traded company. We currently expect this project to reach stabilization in the first quarter of 2021.

In-Process Development Projects - Under Construction

As of December 31, 2020, we had three projects in our in-process development pipeline that were under construction:

•

•

•

Kilroy  Oyster  Point  (Phase  I),  South  San  Francisco,  California.  In  March  2019,  we  commenced  construction  on  Phase  I  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.

Jardine (Living // On Vine), Hollywood, California. We commenced construction on this residential project in December 2018, which encompasses 193
residential units at a total estimated investment of $200.0 million. We currently expect this project to be completed in the first quarter of 2021.

2100  Kettner,  Little  Italy,  San  Diego,  California.  We  commenced  construction  on  this  project  in  September  2019.  This  project  is  comprised  of
approximately 200,000 square feet of office space for a total estimated investment of $140.0 million.

69

Future Development Pipeline

As of December 31, 2020, our future development pipeline included five future projects located in Greater Seattle, the San Francisco Bay Area and San Diego
County with an aggregate cost basis of approximately $1.1 billion, at which we believe we could develop more than 6.0 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.

(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 requirements and demands, construction costs, new supply, regulatory and entitlement processes or project design.

(2) Represents cash paid and costs incurred, including accrued liabilities in accordance with GAAP, as of December 31, 2020.

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 years ended December 31, 2020 and 2019, we capitalized interest on in-process development projects
and  future  development  pipeline  projects  with  an  average  aggregate  cost  basis  of  approximately  $2.0  billion,  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
years ended December 31, 2020 and 2019, we capitalized $79.6 million and $81.2 million, respectively, of interest to our qualifying development projects. For the
years  ended  December  31,  2020  and  2019,  we  capitalized  $21.8  million  and  $25.6  million,  respectively,  of  internal  costs  to  our  qualifying  redevelopment  and
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 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 2020, we completed the sale of one office property to an unaffiliated third party for total gross sales
proceeds of $75.9 million. During 2019, we completed the sale of two office properties to unaffiliated third parties for total gross sales proceeds of $133.8 million.

70

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

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  operating  properties.    We  focus  on  growth
opportunities in West Coast 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 either add immediate Net Operating Income to our portfolio or play a strategic role in our future
growth.

We  did  not  acquire  any  operating  or  development  properties  during  the  year  ended  December  31,  2020.  During  the  year  ended  December  31,  2019,  we
acquired  a  19-building  creative  office  campus  and  two  development  sites  in  three  transactions  for  a  total  cash  purchase  price  of  $359.0  million.  We  generally
finance our acquisitions through proceeds from the issuance of debt and equity securities, borrowings under our unsecured revolving credit facility, proceeds from
our capital recycling program, the assumption of existing debt and cash flows from operations.

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 in 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 2020, 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, and other factors. Consequently, we cannot predict the amounts that will be recorded in future periods related to such incentive compensation.

As  of  December  31,  2020,  there  was  approximately  $35.1  million  of  total  unrecognized  compensation  cost  related  to  outstanding  nonvested  shares  of
restricted  common  stock  and  RSUs  issued  under  share-based  compensation  arrangements.  Those  costs  are  expected  to  be  recognized  over  a  weighted-average
period  of  1.4  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 $35.1 million of unrecognized compensation cost does not reflect the future compensation cost for any potential share-based awards that may be issued
subsequent to December 31, 2020. Share-based compensation expense for potential future

71

awards could be affected by our operating and development performance, financial results, stock price, performance against applicable performance-based vesting
goals, market conditions and other factors. For additional information regarding our equity incentive awards, see Note 15 “Share-Based and Other 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 year ended December 31, 2020.

Our  rental  rates  and  occupancy  are  impacted  by  general  economic  conditions,  including  the  pace  of  regional  economic  growth,  access  to  capital,  and
potentially the current COVID-19 pandemic and restrictions intended to prevent its spread. 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 uncertainty of current market rents as a result
of the COVID-19 pandemic and the impact it has had on recent transaction volume in our markets, 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 December 31, 2020. In addition, it is possible that

72

the COVID-19 pandemic may have an adverse impact on our ability to renew leases or re-lease available space in our properties on favorable terms or at all in the
future,  including  as  a  result  of  a  deterioration  in  the  economic  and  market  conditions  due  to  restrictions  intended  to  prevent  the  spread  of  COVID-19.  These
restrictions and social distancing guidelines limited our ability to physically show space to prospective tenants and impeded initiating new and progressing active
leasing transactions. 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.  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 December 31, 2020, space leased under month-to-month leases, storage leases, vacant space and future lease renewal options not executed as of December 31,
2020.

(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 December 31, 2020 but not yet commenced, the 2021 and 2022 expirations would be reduced by 121,554 and 38,806 square feet, respectively.

In addition to the 1.3 million rentable square feet, or 8.8%, of currently available space in our stabilized portfolio, leases representing approximately 4.4% and
6.6% of the occupied square footage of our stabilized portfolio are scheduled to expire during 2021 and 2022, respectively. The leases scheduled to expire in 2021
and

73

2022 represent approximately 1.4 million rentable square feet, or 8.8%, of our total annualized base rental revenue. Adjusting for leases executed as of December
31, 2020 but not yet commenced, the remaining 2021 and 2022 expirations would be 460,625 and 826,873 square feet, respectively.

Sublease Space. Of our leased space as of December 31, 2020, approximately 1.4 million rentable square feet, or 9.2% of the square footage in our stabilized
portfolio, was available for sublease, primarily in the San Francisco Bay Area and Greater Seattle regions. Of the 9.2% of available sublease space in our stabilized
portfolio as of December 31, 2020, approximately 7.0% was vacant space, and the remaining 2.2% was occupied. Of the approximately 1.4 million rentable square
feet  available  for  sublease  as  of  December  31,  2020,  approximately  21,124  rentable  square  feet  representing  eight  leases  are  scheduled  to  expire  in  2021,  and
approximately 79,232 rentable square feet representing ten leases are scheduled to expire in 2022.

Stabilized Portfolio Information

As of December 31, 2020, our stabilized portfolio was comprised of 117 office properties encompassing an aggregate of approximately 14.6 million rentable
square  feet  and  808  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 December 31, 2020. Our stabilized portfolio also excludes our future development pipeline,
which as of December 31, 2020 was comprised of five potential development sites, representing approximately 61 gross acres of undeveloped land on which we
believe we have the potential to develop more than 6.0 million rentable square feet, depending upon economic conditions.

As of December 31, 2020, the following properties were excluded from our stabilized portfolio:

Results of Operations

Comparison of the Year Ended December 31, 2020 to the Year Ended December 31, 2019

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,  2019  and  still  owned  and  included  in  the
stabilized portfolio as of December 31, 2020, including our 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 projects and the results generated by the following stabilized development properties:

◦
◦
◦
◦
◦

One office development project that was added to the stabilized portfolio in the second quarter of 2019;
One office development project that was added to the stabilized portfolio in the first quarter of 2020;
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; and
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.

Acquisition Properties – includes the results, from the dates of acquisition through the periods presented, for the 19-building creative office campus
we acquired during 2019; and
Disposition Properties – includes the results of the one property disposed of in the second quarter of 2019, the one property disposed of in the fourth
quarter of 2019, and the one property disposed of in the fourth quarter of 2020.

Net Operating Income increased $51.0 million, or 8.6%, for the year ended December 31, 2020 as compared to the year ended December 31, 2019 primarily

resulting from:

•

A decrease of $7.7 million attributable to the Same Store Properties which was driven by the following activity:

•

A decrease in total operating revenues of $19.5 million, or 2.6%, primarily due to the following:

◦

$27.2 million decrease due to the impact of COVID-19, comprised of:

◦

◦

$15.9 million decrease primarily due to charges against rental income due to tenant creditworthiness considerations and abatements
provided to tenants;

$8.1 million decrease due to lower parking income, of which $4.1 million relates to a reduction in the number of monthly parking
spaces rented as a result of COVID-19 stay-at-home orders and $4.0 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  are  in
effect; and

◦

$3.2 million decrease due to lower reimbursable operating expenses;

◦

◦

◦

◦

◦

$8.9 million decrease primarily due to early lease termination fees received in 2019 for two tenants in the San Francisco Bay Area;

$4.2 million net decrease primarily related to the improved credit quality of a tenant in 2019 for which the Company recorded a bad debt
reserve in 2018;

$6.3 million decrease due to lower occupancy primarily in the Greater Los Angeles and San Diego County regions; and

$2.9 million decrease in the tenant reimbursement component of rental income primarily due to a tenant in the San Francisco Bay Area’s
change from a triple net lease to a modified net lease, resulting in payment of expenses directly to vendors, and new tenants with 2020 base
years; partially offset by

$30.3 million increase from new leases and renewals at higher rates at various properties across the portfolio;

•

A  decrease  in  property  and  related  expenses  of  $11.8  million  primarily  due  to  a  decrease  in  reimbursable  expenses  such  as  utilities,  parking,
janitorial,  security,  and  various  other  recurring  expenses  due  to  several  tenants  implementing  work  from  home  policies  due  to  the  COVID-19
pandemic. We anticipate lower reimbursable property expenses and corresponding tenant recoveries as a result of lower usage of our buildings by
tenants while restrictions intended to prevent the spread of COVID-19 are in effect;

Other Expenses and Income

General and Administrative Expenses

General and administrative expenses increased by approximately $11.1 million, or 12.6%, for the year ended December 31, 2020 compared to the year ended

December 31, 2019 primarily due to the following:

•

•

•

•

An  increase  of  $10.7  million  primarily  due  to  increased  severance  costs  in  2020  related  to  the  departure  of  an  executive  officer  and  certain  other
employees, net of lower incentive compensation accruals; and

An increase of $6.9 million primarily due to political contributions for statewide ballot measures; partially offset by

A decrease of $4.0 million due to cost-cutting measures as a result of COVID-19, as well as lower acquisition activity; and

A decrease of $2.5 million primarily due to the settlement of a previously disclosed litigation matter.

Leasing Costs

Leasing costs decreased by $3.1 million, or 41.0%, for the year ended December 31, 2020 compared to the year ended December 31, 2019 primarily due to a
lower  level  of  leasing  activity  during  the  year  ended  December  31,  2020  as  a  result  of  the  COVID-19  pandemic.  See  the  “Factors  that  May  Influence  Future
Results of Operations – Information on Leases Commenced and Executed” and “Liquidity and Capital Resources of the Operating Partnership – Liquidity Uses”
sections for further information.

Depreciation and Amortization

Depreciation  and  amortization  increased  by  approximately  $26.2  million,  or  9.6%,  for  the  year  ended  December  31,  2020  compared  to  the  year  ended

December 31, 2019, primarily due to the following:

•

•

•

•

A decrease of $5.7 million attributable to the Same Store Properties primarily due to write-offs related to early lease terminations and assets that became
fully amortized in 2019; partially offset by

An increase of $28.8 million attributable to the Development Properties;

An increase of $6.3 million attributable to the Acquisition Properties; and

A decrease of $3.2 million attributable to the Disposition Properties.

Interest Expense

The following table sets forth our gross interest expense, including debt discounts/premiums and deferred financing cost amortization and capitalized interest,

Gross  interest  expense,  before  the  effect  of  capitalized  interest  and  deferred  financing  costs,  increased  $20.5  million,  or  15.8%,  for  the  year  ended
December 31, 2020 as compared to the year ended December 31, 2019, primarily due to an increase in the average outstanding debt balance for the year ended
December 31, 2020.

Capitalized  interest  and  deferred  financing  costs  decreased  $1.7  million,  or  2.1%,  for  the  year  ended  December  31,  2020  compared  to  the  year  ended
December 31, 2019, primarily attributable to a decrease in the weighted average interest rate during 2020. During both years ended December 31, 2020 and 2019,
we capitalized interest on in-process development projects and future development pipeline projects with an average aggregate cost basis of approximately $2.0
billion. 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.
Refer to “Part I, Item IA. Risk Factors” included in this report for additional information about the potential impact of the COVID-19 pandemic, and restrictions
intended to prevents 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.

Net income attributable to noncontrolling interests in consolidated property partnerships

Net income attributable  to noncontrolling  interests  in consolidated  property  partnerships  increased  $1.3 million,  or 8.1%, for the year ended December  31,
2020 compared to the year ended December 31, 2019 primarily due to a new lease at a higher rate at one property held in a property partnership in 2020 partially
offset by charges related to the creditworthiness of certain tenants. The amounts reported for the years ended December 31, 2020 and 2019 are comprised of the
noncontrolling interest’s share of net income for 100 First 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 LLC. See Note 11 “Noncontrolling Interests on the Company’s Consolidated Financial Statements” to
our consolidated financial statements included in this report for additional information.

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 year ended December 31, 2020 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.

COVID-19 Liquidity Highlights

As of the date of this report, we have no material debt maturities prior to July 2022, at which time our revolving credit facility matures. As of February 10,
2021, we had approximately $715 million in cash and cash equivalents, with an additional $750.0 million available under our unsecured revolving credit facility, as
a  result  of  settling  various  forward  equity  sale  agreements  and  the  completion  of  a  private  placement  of  $350.0 million  in  unsecured  senior  notes  and  a  public
offering  of  $425.0  million  in  green  unsecured  senior  notes  during  the  year  ended  December  31,  2020.  We  believe  that  this  available  liquidity  makes  us  well
positioned to navigate uncertainty resulting from the COVID-19 pandemic. In addition, as discussed above, 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, as demonstrated by the transactions listed above. Any
future financings, however, will depend on market conditions for capital raises and for the investment of any proceeds and there can be no assurances that we will
successfully obtain such financings.

82

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, common unitholders from the Operating Partnership’s cash flow from operating activities. All such distributions are at the discretion of the
Board of Directors. In 2020, the Company’s distributions exceeded 100% of its taxable income, resulting in a return of capital to its stockholders. 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 for 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  or  is  unable  to  successfully  complete  Section  1031 Exchanges  to
defer  some  or  all  of  the  taxable  gains  related  to  property  dispositions  as  a  result  of  the  COVID-19  pandemic  or  any  other  reason,  the  Company  may  elect  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 December 10, 2020, 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 December 31, 2020 and a corresponding cash distribution of $0.50 per Operating Partnership units is payable to
holders of the Operating Partnership’s common limited partnership interests of record on December 31, 2020, including those owned by the Company. The total
cash quarterly dividends and distributions paid on January 15, 2021 were $58.6 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 December 31, 2020, our total debt as a percentage of total market capitalization was 37.0%, which was calculated based on the closing price per share of

the Company’s common stock of $57.40 on December 31, 2020 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.

2020 Capital and Financing Transactions

We continue to be active in the capital markets and our capital recycling program to finance potential acquisitions and our development activity, as well as our

continued desire to extend our debt maturities. This was primarily a result of the following activity:

85

Capital Recycling Program

•

During the year ended December 31, 2020, we completed the sale of one office building to an unaffiliated third party for gross sales proceeds totaling
approximately $75.9 million.

    Capital Markets / Debt Transactions

•

In addition to obtaining funding from our capital recycling program during 2020, we successfully completed the following financing and capital raising
activities to fund our continued growth. We continued to strengthen our balance sheet and lower our overall cost of capital.

•

•

•

•

Entered into and physically settled forward equity sale agreements with certain financial institutions acting as forward purchasers in connection
with an offering of 5,750,000 shares of common stock at an initial offering  price of $494.5 million,  or $86.00 per share, before underwriting
discounts,  commissions  and  offering  expenses.  Upon  settlement,  the  Company  issued  5,750,000  shares  of  common  stock  for  net  proceeds  of
$474.9 million;

Physically settled all forward equity sale agreements entered into in 2019. Upon settlement, the Company issued 3,147,110 shares of common
stock for net proceeds of $247.3 million;

Entered  into  a  Note  Purchase  Agreement  in  connection  with  the  issuance  and  sale  of  $350.0  million  principal  amount  of  10-year  4.270%
unsecured senior notes due January 2031 pursuant to a private placement; and

Issued $425.0 million aggregate principal amount of 12-year 2.500% green unsecured senior notes due November 2032 in a registered public
offering.

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 non-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, through December 31, 2020, we completed the sale of one property to an unaffiliated third party for gross
sales proceeds totaling approximately $75.9 million. During 2019, we completed the sale of two properties to unaffiliated third parties for total gross sales proceeds
totaling approximately $133.8 million. See “—Factors that May Influence Future Operations” and Note 4 “Dispositions” to our consolidated financial statements
included in this report for additional information.

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.

Forward Equity Offering and Settlement

On February 18, 2020, the Company entered into forward equity sale agreements with certain financial institutions acting as forward purchasers in connection
with  an  offering  of  5,750,000  shares  of  common  stock  at  an  initial  gross  offering  price  of  $494.5  million,  or  $86.00  per  share,  before  underwriting  discounts,
commissions and offering expenses. The forward purchasers borrowed and sold an aggregate of 5,750,000 shares of common stock in the offering.

On March 25, 2020, the Company physically settled these forward equity sale agreements. Upon settlement, the Company issued 5,750,000 shares of common
stock for net proceeds of $474.9 million and contributed the net proceeds to the Operating Partnership in exchange for an equal number of units in the Operating
Partnership.

87

At-The-Market Stock Offering Program

Under our current at-the-market 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 whereby, at our discretion, the forward purchasers may borrow and sell shares of our common stock under our at-the-market program (see “Note
13. Stockholders’ Equity of the Company” to our consolidated financial statements included in this report for additional information).

During the year ended December  31, 2019, we executed  various 12-month forward equity sale agreements  under our at-the-market  program with financial
institutions  acting  as  forward  purchasers  to  sell  3,147,110  shares  of  common  stock  at  a  weighted  average  sales  price  of  $80.08  per  share  before  underwriting
discounts, commissions and offering expenses.

In  March  2020,  we  physically  settled  all  forward  equity  sale  agreements  entered  into  in  2019.  Upon  settlement,  the  Company  issued  3,147,110  shares  of
common stock for net proceeds of $247.3 million and contributed the net proceeds to the Operating Partnership in exchange for an equal number of units in the
Operating Partnership. We did not enter into any forward equity sale agreements under our at-the-market program during the year ended December 31, 2020.

Since commencement of our current at-the-market program, we have completed sales of 3,594,576 shares of common stock through December 31, 2020. As of
December  31,  2020,  we  may  offer  and  sell  shares  of  our  common  stock  having  an  aggregate  gross  sales  price  up  to  approximately  $214.2  million  under  this
program.

The company did not complete any direct sales of common stock under the program during the years ended December 31, 2020 or 2019. The following table
sets forth information regarding settlements of forward equity sale agreements for the year ended December 31, 2020. The Company did not settle any forward

The  proceeds  from  sales  were  used  to  fund  development  expenditures,  and  general  corporate  purposes.  Actual  future  sales  will  depend  upon  a  variety  of
factors, including, but not limited to market conditions, the trading price of the Company’s common stock and our capital needs. We have no obligation to sell the
remaining shares available for sale under this program.

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. During the year
ended December 31, 2020, the Company’s stock price ranged from $46.46 to $88.28, a 90% swing, as a result of COVID-19 and the resultant impact on the capital
markets  and  economy.  If  current  conditions  continue  for  an  extended  period  of  time,  capital  raising  could  be  more  challenging  than  under  conditions  prior  to
COVID-19. When the Company receives proceeds from the sales of its preferred or common stock, it generally

88

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 Senior Notes - Registered Offering

In August 2020, the Operating Partnership issued $425.0 million aggregate principal amount of green unsecured senior notes in a registered public offering.
The outstanding balance of the unsecured senior notes is included in unsecured debt, net of an initial issuance discount of $2.7 million, on our consolidated balance
sheets. The unsecured senior notes, which are scheduled to mature on November 15, 2032, require semi-annual interest payments each May and November based
on a stated annual interest rate of 2.500%. The Operating Partnership may redeem the notes at any time prior to August 15, 2032, either in whole or in part, subject
to the payment of an early redemption premium prior to a par call option period commencing three months prior to maturity.

Unsecured Senior Notes - Private Placement

In April 2020, the Operating Partnership entered into a Note Purchase Agreement in connection with the issuance and sale of $350.0 million principal amount
of  the  Operating  Partnership's  4.270%  Senior  Notes  due  January  31,  2031 (the  “Notes”),  pursuant  to  a  private  placement.  The  Notes  mature  on  their  due  date,
unless earlier redeemed or prepaid pursuant to the terms of the Note Purchase Agreement. Interest on the Notes is payable semi-annually in arrears on April 18 and
October 18 of each year beginning October 18, 2020.

(5) Amounts represent cash commitments under signed leases and contracts for operating properties, excluding tenant-funded tenant improvements, and for other contractual commitments.

The timing of these expenditures may fluctuate.

(6) Amounts  represent  commitments  under  signed  leases  for  pre-leased  development  projects  and  contractual  commitments  for  projects  in  the  tenant  improvement  phase  and  under
construction as of December 31, 2020. The timing of these expenditures may fluctuate based on the ultimate progress of construction. We may start additional construction in 2021 (see
“—Development” for additional information).

Other Liquidity Uses

Development

As of December 31, 2020, we had three development projects under construction.  These projects have a total estimated investment of approximately $910
million, of which we have incurred approximately $600 million, net of retention, and committed an additional $310 million as of December 31, 2020. In addition,
as of December 31, 2020, we had three development projects in the tenant improvement phase. These projects have a total estimated investment of approximately
$720 million of which we have incurred approximately $610 million, net of retention, and committed an additional $110 million as of December 31, 2020. We also
had  three  stabilized  development  projects  with  a  total  estimated  investment  of  $1.2  billion,  of  which  approximately  $64  million  remains  to  be  spent  in  2021.
Including  the  commitment  information  in  the  table  above  we  currently  believe  we  may  spend  between $400  million  to  $500  million on  development  projects
throughout 2021.  Ultimate timing of these expenditures may fluctuate given construction progress and leasing status of the projects. Additionally, the COVID-19
pandemic, and restrictions intended to prevent its spread, could cause delays or increase costs associated with building materials or construction services necessary
for construction in the future, which could adversely impact our ability to continue or complete construction as planned, on budget or at all, and may delay the start
of construction on our future development pipeline projects. We expect that any material additional development activities will be funded with

91

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.

Debt Maturities

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  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. Refer to “Part I, Item IA. Risk Factors”
included in this report for additional information about the potential impact of the COVID-19 pandemic, and restrictions intended to prevents 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.  Our  next  debt  maturity  occurs  in  July  2022  and  relates  to  our  unsecured  revolving  credit  facility,  under  which  we  currently  do  not  have  any
amounts borrowed.

Potential Future Acquisitions

We did not acquire any operating properties during the year ended December 31, 2020. During 2019, we acquired a 19-building creative office campus and
two development sites for a total of $359.0 million in cash. These transactions were funded through various capital raising activities and liquidity as discussed in
“—Liquidity Sources”.

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  operating  properties,  dependent  on  market  conditions  and
business cycles, among other factors.  We focus on growth opportunities in West Coast markets populated by knowledge and creative based tenants in a variety of
industries,  including  technology,  media,  healthcare,  life  sciences,  entertainment  and  professional  services.    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.  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 December 31, 2020, 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 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.

Potential Future Leasing Costs and Capital Improvements

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.

92

For properties within our stabilized portfolio, excluding our development properties, we believe we could spend approximately $75 million to $85 million in
capital improvements, tenant improvements and leasing costs in 2021, in addition to the lease and contractual commitments included in our contractual obligations
table above. The amount we ultimately spend will depend on leasing activity during 2021.

The following table sets forth our historical actual capital expenditures, and tenant improvements and leasing costs for deals commenced, excluding tenant-
funded tenant improvements, for renewed and re-tenanted space within our stabilized portfolio for each of the years ended December 31, 2020, 2019 and 2018 on a

Capital expenditures per square foot increased in 2020 as compared to 2019 due to an increase in general building improvements during 2020. We currently
anticipate  capital  expenditures  for  2021  to  be  consistent  with  2020  levels.  Replacement  tenant  improvements  and  leasing  commissions  increased  in  2020  as
compared to 2019 primarily due to large leases commenced in the San Francisco Bay Area and San Diego County regions in 2020 and overall reduced replacement
tenant square feet in 2020. Renewal tenant improvements and leasing commissions per square foot increased in 2020 as compared to 2019 primarily due to a large
lease renewed in the San Francisco Bay Area in 2020 and overall reduced renewal tenant square feet in 2020. We currently anticipate tenant improvement and
leasing commissions for 2021 to be higher than 2020 levels due to an expected increase in leasing activity as well as the leases executed in prior years, including
early renewals of lease expirations; however, ultimate costs incurred will depend upon market conditions in each of our submarkets and actual leasing activity.

Distribution Requirements

For a discussion of our dividend and distribution requirements, see “Liquidity and Capital Resources of the Company —Distribution Requirements.”

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, and restrictions intended to prevents its spread, on capital and credit markets and our tenants (refer to “Part I, Item IA. Risk
Factors” of this report 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 term loan facility, unsecured term loan, 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 and Private Placement Notes (as defined in the applicable Credit Agreements):
Total debt to total asset value
Fixed charge coverage ratio
Unsecured debt ratio
Unencumbered asset pool debt service coverage

Unsecured Senior Notes due 2023, 2024, 2025, 2028, 2029, 2030 and 2032 (as defined in the applicable

Indentures):

The Operating Partnership was in compliance with all of its debt covenants as of December 31, 2020. 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. In response to the COVID-19 pandemic, we have completed stress
testing of our various financial covenants assuming decreases in rental income and determined that the Operating Partnership has adequate cushion between actual
performance and debt covenant levels. However, in the event of an economic

94

 
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

The following summary discussion of our consolidated historical cash flow is based on the consolidated statements of cash flows in Item 15. “Exhibits and

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 increased by $69.1 million, or 17.9%, for the
year  ended  December  31,  2020  compared  to  the  year  ended  December  31,  2019  primarily  as  a  result  of  net  changes  in  other  assets  related  to  the  timing  of
expenditures and net cash flow from operations of development properties that became stabilized during the year ended December 31, 2020.

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. Our net cash used
in investing activities decreased by $686.2 million, or 55.9%, for the year ended December 31, 2020 compared to the year ended December 31, 2019, primarily due
to lower expenditures for development properties and undeveloped land, no acquisitions completed and lower disposition activity during the year ended December
31, 2020.

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. Our net cash provided by financing activities increased by $86.3 million or 11.5% for the year ended December 31, 2020 compared to
the  year  ended  December  31,  2019,  primarily  due  to  the  net  proceeds  received  upon  physical  settlement  of  our  February  2020  forward  equity  sale  agreements
pursuant to which we issued 5,750,000 shares of common stock and the forward equity sale agreements entered into during the year ended December 31, 2019
under our at-the-market program pursuant to which we issued 3,147,110 shares of common stock during the year ended December 31, 2020 partially offset by net
repayments on our unsecured revolving credit facility during the year ended December 31, 2020 compared to net borrowings during the year ended December 31,
2019.

Off-Balance Sheet Arrangements

As of December 31, 2020 and as of the date this report was filed, we did not have any off-balance sheet transactions, arrangements, or obligations, including

contingent obligations.

Non-GAAP Supplemental Financial Measure: Funds From Operations

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  majority  of  the  Company’s  leases  require  tenants  to  pay  for  recoveries  and  escalation  charges  based  upon  the  tenant’s  proportionate  share  of,  and/or

increases in, real estate taxes and certain operating costs, which reduce the Company’s exposure to increases in operating costs resulting from inflation.

New Accounting Pronouncements and Auditing Standards

For  a  discussion  of  new  accounting  pronouncements  see  Note  2  “Basis  of  Presentation  and  Significant  Accounting  Policies”  to  our  consolidated  financial

statements included in this report.

On June 1, 2017, the Public Company Accounting Oversight Board (PCAOB) issued Auditing Standard 3101, The Auditor’s Report on an Audit of Financial
Statements When the Auditor Expresses an Unqualified Opinion (“AS 3101”). As a result of AS 3101, the most significant change to the auditor’s report on the
financial statements is a new requirement to describe critical audit matters arising from the audit of the current period’s financial statements in the auditor’s report.
The requirements related to critical audit matters in AS 3101 were effective for audits of fiscal years ending on or after June 30, 2019, for large accelerated filers;
and for fiscal years ending on or after December 15, 2020, for all other companies to which the requirements apply. Therefore, critical audit matters are included in
the Report of Independent Registered Public Accounting Firm for the Company’s and the Operating Partnership’s consolidated financial statements as of and for
the years ended December 31, 2020.

ITEM 7A.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary market risk we face is interest rate risk. We seek to mitigate this risk by following established risk management policies and procedures. These
policies include maintaining prudent amounts of debt, including a greater amount of fixed-rate debt as compared to variable-rate debt in our portfolio, and may
include the periodic use of derivative instruments. As of December 31, 2020 and 2019, we did not have any interest-rate sensitive derivative assets or liabilities.
Information  about  our  changes  in  interest  rate  risk  exposures  from  December  31,  2019  to  December  31,  2020  is  incorporated  herein  by  reference  from
“Item  7.  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  —Liquidity  and  Capital  Resources  of  the  Operating
Partnership.”

Interest Rate Risk

As of December 31, 2020, 100.0% of our total outstanding debt of $4.0 billion (before the effects of debt discounts and deferred financing costs) bore interest
at fixed rates since our only variable-rate debt instrument was our unsecured revolving credit facility which had no outstanding balance at December 31, 2020. All
of our interest rate sensitive financial instruments are held for purposes other than trading purposes. In general, interest rate fluctuations applied to our variable-rate
debt  will  impact  our  future  earnings  and  cash  flows.  Conversely,  interest  rate  fluctuations  applied  to  our  fixed-rate  debt  will  generally  not  impact  our  future
earnings and cash flows, unless such instruments mature or are otherwise terminated and need to be refinanced. However, interest rate fluctuations will impact the
fair value of the fixed-rate debt instruments.

We  generally  determine  the  fair  value  of  our  secured  debt,  unsecured  debt,  and  unsecured  revolving  credit  facility  by  performing  discounted  cash  flow
analyses  using  an  appropriate  market  discount  rate.  We  calculate  the  market  rate  by  obtaining  period-end  treasury  rates  for  maturities  that  correspond  to  the
maturities of our fixed-rate debt and then adding an appropriate credit spread based on information obtained from third-party financial institutions. These credit
spreads  take  into  account  factors,  including  but  not  limited  to,  our  credit  profile,  the  tenure  of  the  debt,  amortization  period,  whether  the  debt  is  secured  or
unsecured, and the loan-to-value ratio of the debt to the collateral, amongst other factors. These calculations are significantly affected by the assumptions used,
including the discount rate, credit spreads and estimates of future cash flow. We calculate the market rate of our unsecured revolving credit facility by obtaining the
period-end  London Interbank  Offered  Rate  (“LIBOR”) and then  adding an appropriate  credit  spread  based on our credit  ratings, and the amended terms  of our
unsecured revolving credit facility agreement. We determine the fair value of each of our publicly traded unsecured senior notes based on their quoted trading price
at the end of the reporting period, if such prices are available. See Note 19 “Fair Value Measurements and Disclosures” and Note 2 “Basis of Presentation and
Significant Accounting Policies” in the consolidated financial statements included in this report for additional information on the fair value of our financial assets
and liabilities as of December 31, 2020 and December 31, 2019.

At December 31, 2020, there was no outstanding balance on our $750.0 million unsecured revolving credit facility; however, it was available for borrowing at
the following variable rate: LIBOR plus a spread of 1.00% (weighted average interest rate of 1.14%). As of December 31, 2019, the total outstanding balance of
our variable-rate debt was comprised of borrowings on our unsecured revolving credit facility of $245.0 million and unsecured term loan facility of $150.0 million,
which were indexed to LIBOR plus a spread of 1.00% (weighted average interest rate of 2.76%) and LIBOR plus a spread of 1.10% (weighted average interest rate
of 2.85%), respectively.

The  total  carrying  value  of  our  fixed-rate  debt  was  approximately  $3.9 billion  and  $3.2 billion  as  of  December  31,  2020 and  2019,  respectively.  The  total
estimated  fair  value  of  our  fixed-rate  debt  was  approximately  $4.4  billion  and  $3.4  billion  as  of  December  31,  2020  and  2019,  respectively.  For  sensitivity
purposes, a 100 basis point increase in the discount rate equates to a decrease in the total fair value of our fixed-rate debt of approximately $264.2 million, or 6.0%,
as  of  December  31,  2020.  Comparatively,  a  100  basis  point  increase  in  the  discount  rate  equates  to  a  decrease  in  the  total  fair  value  of  our  fixed-rate  debt  of
approximately $203.3 million, or 6.0%, as of December 31, 2019.

99

The Financial Conduct Authority (the authority that regulates LIBOR) has announced it intends to stop compelling banks to submit rates for the calculation of
LIBOR at some point in the future. The Alternative Reference Rates Committee (“ARRC”) has proposed that the Secured Overnight Financing Rate (“SOFR”) is
the rate that represents best practice as the alternative to LIBOR for use in derivatives and other financial contracts that are currently indexed to LIBOR. ARRC has
proposed a paced market transition plan to SOFR from LIBOR and organizations are currently working on industry wide and company specific transition plans as
it relates to derivatives and cash markets exposed to LIBOR. As our variable-rate debt is indexed to LIBOR, we are monitoring this activity and evaluating the
related risks.

ITEM 9A.    CONTROLS AND PROCEDURES    

Kilroy Realty Corporation

The  Company  maintains  disclosure  controls  and  procedures  (as  defined  in  Rule  13a-15(e)  or  Rule  15d-15(e)  under  the  Exchange  Act)  that  are  designed  to
ensure that information required to be disclosed in the Company’s reports under the Exchange Act is processed, recorded, summarized, and reported within the
time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including the Chief Executive
Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls
and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of
achieving  the  desired  control  objectives,  and  management  is  required  to  apply  its  judgment  in  evaluating  the  cost-benefit  relationship  of  possible  controls  and
procedures.

As required by SEC Rule 13a-15(b), the Company carried out an evaluation, under the supervision and with the participation of management, including the
Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures as of December 31,
2020, the end of the period covered by this report. Based on the foregoing, the Company’s Chief Executive Officer and Chief Financial Officer concluded, as of
that time, the disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There  have  been  no  changes  that  occurred  during  the  fourth  quarter  of  the  most  recent  year  covered  by  this  report  in  the  Company’s  internal  control  over
financial  reporting  identified  in  connection  with the evaluation  referenced  above  that  have materially  affected,  or are  reasonably  likely  to materially  affect,  our
internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Internal control over financial  reporting is a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer and
effected  by  our  board  of  directors,  management,  and  other  personnel  to  provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the
preparation of financial statements for external purposes in accordance with GAAP. Internal control over financial reporting includes those policies and procedures
that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and
expenditures are being made only in accordance with authorizations of management and directors; and (3) provide reasonable assurance regarding prevention or
timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the consolidated financial statements.

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is
supported by written policies and procedures and by an appropriate segregation of responsibilities and duties. The Company has used the criteria set forth in the
Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission to assess our internal control
over financial reporting. Based upon this assessment, management concluded that internal control over financial reporting operated effectively as of December 31,
2020.

Deloitte & Touche LLP, the Company’s independent registered public accounting firm, has audited the Company’s financial statements and has issued a report

on the effectiveness of the Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of
Kilroy Realty Corporation

Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Kilroy Realty Corporation and subsidiaries (the “Company”) as of December 31, 2020, based on
criteria  established  in  Internal  Control  -  Integrated  Framework  (2013) issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission
(COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on
criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial
statements as of and for the year ended December 31, 2020, of the Company and our report dated February 12, 2021, expressed an unqualified opinion on those
financial statements.

Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal
control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express
an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are
required  to  be  independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the
Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance
about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal
control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control
based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable
basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial
reporting  includes  those  policies  and  procedures  that  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the
transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of
financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  company  are  being  made  only  in
accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of
unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Also,  projections  of  any  evaluation  of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with
the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of
Kilroy Realty Corporation

Opinion on the Financial Statements
We  have  audited  the  accompanying  consolidated  balance  sheets  of  Kilroy  Realty  Corporation  and  subsidiaries  (the  “Company”)  as  of  December  31,  2020  and
2019, the related consolidated statements of operations, equity, and cash flows, for each of the three years in the period ended December 31, 2020, and the related
notes and the schedules listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly,
in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the
three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal
control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee
of Sponsoring Organizations of the Treadway Commission and our report dated February 12, 2021 expressed an unqualified opinion on the Company’s internal
control over financial reporting.

Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements
based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance
with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We  conducted  our  audits  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to
assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the
accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe
that our audits provide a reasonable basis for our opinion.

Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be
communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially
challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken
as  a  whole,  and  we  are  not,  by  communicating  the  critical  audit  matter  below,  providing  a  separate  opinion  on  the  critical  audit  matter  or  on  the  accounts  or
disclosures to which it relates.

Rental  income,  deferred  revenue  and  acquisition-related  intangible  liabilities  -  Timing  of  Development  Property  Revenue  Recognition  and  Ownership  of
Tenant Improvements - Refer to Notes 2 and 10 to the financial statements

Critical Audit Matter Description
The  timing  of  when  the  Company  commences  rental  revenue  recognition  depends  largely  on  the  Company’s  determination  of  who  is  the  owner  of  the  tenant
improvements of the leased space for accounting purposes. When management concludes that the Company is the owner of the tenant improvements, the Company
records the cost to construct the tenant improvements as capital assets, and commences rental revenue recognition when the tenant takes possession of or controls
the finished space, which is generally when the improvements being recorded are substantially complete. When management concludes that the Company is not the
owner and the tenant is the owner of certain tenant improvements for accounting purposes, the Company records their contribution towards those

F - 2

tenant-owned  improvements as a lease incentive,  which is amortized  as a reduction  to rental  revenue on a straight-line  basis over the term of the related  lease.
Rental revenue recognition begins when the tenant takes possession of or controls the physical use of the leased space. Control is typically transferred when the
Company  has  completed  all  its  obligations  under  the  lease  agreement  in  order  for  the  leased  space  to  be  used  by  the  tenant.  The  Company’s  determination  of
whether its obligations have been met and control has been transferred to the tenant can be complex for large development properties.

Construction for large development properties can include certain tenant improvements that are landlord-owned and others that are tenant-owned improvements. In
making the determination of ownership of the tenant improvements, management considers numerous factors and performs a detailed evaluation of each individual
lease. No one factor is determinative in reaching a conclusion and the factors management evaluates include but are not limited to (i) whether the lease agreement
requires  landlord  approval  of  how  the  tenant  improvement  allowance  is  spent  prior  to  installation  of  the  tenant  improvements  (ii)  whether  the  lease  agreement
requires  the  tenant  to  provide  evidence  to  the  landlord  supporting  the  cost  and  what  the  tenant  improvement  allowance  was  spent  on  prior  to  payment  by  the
landlord  for  such  tenant  improvements  (iii)  whether  the  tenant  improvements  are  unique  to  the  tenant  or  reusable  by  other  tenants  (iv)  whether  the  tenant  is
permitted to alter or remove the tenant improvements without the consent of the landlord and (v) whether the ownership of the tenant improvements remains with
the landlord or remains with the tenant at the end of the lease term. Further, large development properties can deliver leased space in phases, resulting in various
revenue  commencement  dates  with  judgment  surrounding  when  the  tenant  improvements  that  are  landlord-owned,  for  a  particular  phase,  are  substantially
complete.

Given the nature of construction work on large development properties, auditing management's judgments regarding the determination of the owner of the tenant
improvements,  when  control  of  the  leased  space  transfers  to  the  tenant  and  when  to  begin  rental  revenue  recognition  involves  especially  subjective  judgment.
Performing audit procedures to evaluate the reasonableness of management’s conclusion on ownership of the tenant improvements, specifically related to whether
the tenant improvements are unique to the tenant or reusable by other tenants, as well as the appropriate date for when control of the leased space transfers to the
tenant required a high degree of auditor judgment and an increased extent of effort.

How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to determining the ownership of tenant improvements and when control of the leased space transfers to the tenant for development
properties, thus the timing of the commencement of rental revenue recognition, included the following, among others:

• We tested the effectiveness of controls over revenue recognition, including those over the ownership of tenant improvements and the determination of

when the tenant took possession of or controlled the leased space.

• We evaluated the reasonableness of management’s conclusions regarding the Company’s ownership of tenant improvements by:

–

–
–

Evaluating  the  Company’s  and  the  tenant’s  respective  obligations  as  governed  by  the  lease  agreements  for  selected  leases  against  criteria  for
establishing ownership.
Testing documentation supporting the nature of tenant improvements.
Performing  on-site  inspections  of  selected  development  properties,  as  needed,  to  evaluate  the  nature  of  tenant  improvements,  particularly  the
uniqueness of the improvements.

• We evaluated the reasonableness of management’s conclusions regarding the possession of or control of the completed leased space and corresponding

commencement of rental revenue recognition for development properties by:
–
–

Testing documentation from construction contractors, architects, and city building inspection sign offs on temporary certificates of occupancy.
Performing on-site inspections of selected development properties near the planned rental revenue recognition commencement date, as needed, to
observe the status of the site and tenant improvements to evaluate whether control of the leased space had been or was ready to be transferred to the
tenant.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Partners of
Kilroy Realty, L.P.

Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Kilroy Realty, L.P. and subsidiaries (the “Operating Partnership”) as of December 31, 2020 and
2019, the related consolidated statements of operations, capital, and cash flows, for each of the three years in the period ended December 31, 2020, and the related
notes and the schedules listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly,
in all material respects, the financial position of the Operating Partnership as of December 31, 2020 and 2019, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Operating Partnership’s
internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the
Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 12, 2021, expressed an unqualified opinion on the Operating
Partnership’s internal control over financial reporting.

Basis for Opinion
These  financial  statements  are  the  responsibility  of  the  Operating  Partnership’s  management.  Our  responsibility  is  to  express  an  opinion  on  the  Operating
Partnership’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect
to  the  Operating  Partnership  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the  Securities  and  Exchange
Commission and the PCAOB.

We  conducted  our  audits  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to
assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the
accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe
that our audits provide a reasonable basis for our opinion.

Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be
communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially
challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken
as  a  whole,  and  we  are  not,  by  communicating  the  critical  audit  matter  below,  providing  a  separate  opinion  on  the  critical  audit  matter  or  on  the  accounts  or
disclosures to which it relates.

Rental  Income,  deferred  revenue  and  acquisition-related  intangible  liabilities  -  Timing  of  Development  Property  Revenue  Recognition  and  Ownership  of
Tenant Improvements - Refer to Notes 2 and 10 to the financial statements

Critical Audit Matter Description
The timing of when the Operating Partnership commences rental revenue recognition depends largely on the Operating Partnership’s determination of who is the
owner of the tenant improvements of the leased space for accounting purposes. When management concludes that the Operating Partnership is the owner of the
tenant improvements, the Operating Partnership records the cost to construct the tenant improvements as capital assets, and commences rental revenue recognition
when the tenant takes possession of or controls the finished space, which is generally when the improvements being recorded are substantially complete. When
management concludes that the Operating Partnership is not the owner and the tenant is the owner of certain tenant improvements for accounting

F - 8

purposes, the Operating Partnership records their contribution towards those tenant-owned improvements as a lease incentive, which is amortized as a reduction to
rental  revenue  on a straight-line  basis over the term  of the related  lease. Rental  revenue  recognition  begins when the tenant  takes  possession of or controls  the
physical use of the leased  space. Control is typically  transferred  when the Operating  Partnership  has completed  all its obligations  under the lease  agreement  in
order  for  the  leased  space  to  be  used  by  the  tenant.  The  Operating  Partnership’s  determination  of  whether  its  obligations  have  been  met  and  control  has  been
transferred to the tenant can be complex for large development properties.

Construction for large development properties can include certain tenant improvements that are landlord-owned and others that are tenant-owned improvements. In
making the determination of ownership of the tenant improvements, management considers numerous factors and performs a detailed evaluation of each individual
lease. No one factor is determinative in reaching a conclusion and the factors management evaluates include but are not limited to (i) whether the lease agreement
requires  landlord  approval  of  how  the  tenant  improvement  allowance  is  spent  prior  to  installation  of  the  tenant  improvements  (ii)  whether  the  lease  agreement
requires  the  tenant  to  provide  evidence  to  the  landlord  supporting  the  cost  and  what  the  tenant  improvement  allowance  was  spent  on  prior  to  payment  by  the
landlord  for  such  tenant  improvements  (iii)  whether  the  tenant  improvements  are  unique  to  the  tenant  or  reusable  by  other  tenants  (iv)  whether  the  tenant  is
permitted to alter or remove the tenant improvements without the consent of the landlord and (v) whether the ownership of the tenant improvements remains with
the landlord or remains with the tenant at the end of the lease term. Further, large development properties can deliver leased space in phases, resulting in various
revenue  commencement  dates  with  judgment  surrounding  when  the  tenant  improvements  that  are  landlord-owned,  for  a  particular  phase,  are  substantially
complete.

Given the nature of construction work on large development properties, auditing management's judgments regarding the determination of the owner of the tenant
improvements,  when  control  of  the  leased  space  transfers  to  the  tenant  and  when  to  begin  rental  revenue  recognition  involves  especially  subjective  judgment.
Performing audit procedures to evaluate the reasonableness of management’s conclusion on ownership of the tenant improvements, specifically related to whether
the tenant improvements are unique to the tenant or reusable by other tenants, as well as the appropriate date for when control of the leased space transfers to the
tenant required a high degree of auditor judgment and an increased extent of effort.

How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to determining the ownership of tenant improvements and when control of the leased space transfers to the tenant for development
properties, thus the timing of the commencement of rental revenue recognition, included the following, among others:

• We tested the effectiveness of controls over revenue recognition, including those over the ownership of tenant improvements and the determination of

when the tenant took possession of or controlled the leased space.

• We evaluated the reasonableness of management’s conclusions regarding the Operating Partnership’s ownership of tenant improvements by:

–

–
–

Evaluating the Operating Partnership’s and the tenant’s respective obligations as governed by the lease agreements for selected leases against criteria
for establishing ownership.
Testing documentation supporting the nature of tenant improvements.
Performing  on-site  inspections  of  selected  development  properties,  as  needed,  to  evaluate  the  nature  of  tenant  improvements,  particularly  the
uniqueness of the improvements.

• We evaluated the reasonableness of management’s conclusions regarding the possession of or control of the completed leased space and corresponding

commencement of rental revenue recognition for development properties by:
–
–

Testing documentation from construction contractors, architects, and city building inspection sign offs on temporary certificates of occupancy.
Performing on-site inspections of selected development properties near the planned rental revenue recognition commencement date, as needed, to
observe the status of the site and tenant improvements to evaluate whether control of the leased space had been or was ready to be transferred to the
tenant.

Organization and Ownership

Kilroy Realty Corporation (the “Company”) is a self-administered real estate investment trust (“REIT”) active in premier office and mixed-use submarkets
along  the  West  Coast.  We  own,  develop,  acquire  and  manage  real  estate  assets,  consisting  primarily  of  Class  A  properties  in  the  coastal  regions  of  Greater
Los Angeles, San Diego County, the San Francisco Bay Area and Greater Seattle, which we believe have strategic advantages and strong barriers to entry. Class A
real  estate  encompasses  attractive  and  efficient  buildings  of  high  quality  that  are  attractive  to  tenants,  are  well-designed  and  constructed  with  above-average
material,  workmanship  and  finishes  and  are  well-maintained  and  managed.  We  qualify  as  a  REIT  under  the  Internal  Revenue  Code  of  1986,  as  amended  (the
“Code”). The Company’s common stock is publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “KRC.”

We own our interests in all of our real estate assets through Kilroy Realty, L.P. (the “Operating Partnership”). We generally conduct substantially all of our
operations through the Operating Partnership. Unless stated otherwise or the context indicates otherwise, the terms “Kilroy Realty Corporation” or the “Company,”
“we,” “our,” and “us” refer to Kilroy Realty Corporation and its consolidated subsidiaries and the term “Operating Partnership” refers to Kilroy Realty, L.P. and its
consolidated subsidiaries. The descriptions of our business, employees, and properties apply to both the Company and the Operating Partnership.

Our stabilized portfolio of operating properties was comprised of the following properties at December 31, 2020:

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 at the historical cost of the property as the projects or phases of projects are placed in service.

During the year ended December 31, 2020, we added four development projects to our stabilized portfolio consisting of 750,370 square feet of office space in
San Francisco, California, 361,388 square feet of office space in Hollywood, California, 95,871 square feet of retail space and 608 residential units in San Diego,
California.  As  of  December  31,  2020,  the  following  properties  were  excluded  from  our  stabilized  portfolio.  We  did  not  have  any  redevelopment  properties  or
properties held for sale at December 31, 2020.

In addition to the estimated office and life science rentable square feet noted above, development projects under construction also include 193 residential units.

Our  stabilized  portfolio  also  excludes  our  future  development  pipeline,  which  as  of  December  31,  2020  was  comprised  of  five  future  development  sites,

representing approximately 61 gross acres of undeveloped land.

As of December 31, 2020, all of our properties and development projects were owned and all of our business was conducted in the state of California with the
exception of eight stabilized office properties, one development project in the tenant improvement phase and one future development project located in the state of
Washington. All of our properties and development projects are 100% owned, excluding four office properties owned by three consolidated property partnerships.
Two of the three consolidated property partnerships, 100 First Street Member, LLC (“100 First LLC”) and 303 Second Street Member, LLC (“303 Second LLC”),
each owned one office property in San Francisco, California through subsidiary REITs. As of December 31, 2020, the Company owned a 56% common equity
interest  in  both  100 First  LLC and  303  Second  LLC. The  third  consolidated  property  partnership,  Redwood City  Partners,  LLC (“Redwood  LLC”)  owned two
office properties in Redwood City, California. As of December 31, 2020, the Company owned an approximate 93% common equity interest in Redwood LLC. The
remaining interests in all three property partnerships were owned by unrelated third parties.

As  of  December  31,  2020,  the  Company  owned  an  approximate  99.0%  common  general  partnership  interest  in  the  Operating  Partnership.  The  remaining
approximate 1.0% common limited partnership interest in the Operating Partnership as of December 31, 2020 was owned by non-affiliated investors and certain of
our executive officers and directors. Both the general and limited common partnership interests in the Operating Partnership are denominated in common units.
Generally, the number of common units held by the Company is equivalent to the number of outstanding shares of the Company’s common stock, and the rights of
all the common units to quarterly distributions and payments in liquidation mirror those of the Company’s common stockholders. The common limited partners
have  certain  redemption  rights  as  provided  in  the  Operating  Partnership’s  Seventh  Amended  and  Restated  Agreement  of  Limited  Partnership,  as  amended,  the
“Partnership Agreement”. With the exception of the Operating Partnership and our consolidated property partnerships, all of our subsidiaries are wholly-owned.

Basis of Presentation

The  consolidated  financial  statements  of  the  Company include  the consolidated  financial  position  and  results  of  operations  of the  Company, the  Operating
Partnership, 303 Second LLC, 100 First LLC, Redwood LLC and all of our wholly-owned and controlled subsidiaries. The consolidated financial statements of the
Operating Partnership include the consolidated financial position and results of operations of the Operating Partnership, 303 Second LLC, 100 First LLC, Redwood
LLC  and  all  of  our  wholly-owned  and  controlled  subsidiaries.  All  intercompany  balances  and  transactions  have  been  eliminated  in  the  consolidated  financial
statements.

Partially Owned Entities and Variable Interest Entities

At December 31, 2020 the consolidated financial statements of the Company included two VIEs in addition to the Operating Partnership: 100 First LLC and
303 Second LLC. At December 31, 2020, the Company and the Operating Partnership were determined to be the primary beneficiaries of these two VIEs since we
had  the  ability  to  control  the  activities  that  most  significantly  impact  each  of  the  VIEs’  economic  performance.  As of  December  31, 2020, the  two VIEs’  total
assets, liabilities and noncontrolling interests included on our consolidated balance sheet were approximately $469.3 million (of which $394.6 million related to
real estate held for investment), approximately $33.9 million and approximately $191.9 million, respectively. Revenues, income and net assets generated by 100
First LLC and 303 Second LLC may only be used to settle their contractual obligations, which primarily consist of operating expenses, capital expenditures and
required distributions.

At  December  31,  2019,  the  consolidated  financial  statements  of  the  Company  included  four  VIEs  in  addition  to  the  Operating  Partnership:  two  of  the
consolidated property partnerships, 100 First LLC and 303 Second LLC, and two entities established during the fourth quarter of 2019 to facilitate a Section 1031
Exchange. At December 31, 2019, the Company and the Operating Partnership were determined to be the primary beneficiaries of these four VIEs since we had the
ability  to  control  the  activities  that  most  significantly  impact  each  of  the  VIEs’  economic  performance.  At  December  31,  2019,  the  four  VIEs’  total  assets,
liabilities and noncontrolling interests included on our consolidated balance sheet were approximately $676.7 million (of which $598.0 million related to real estate
held for investment on our consolidated balance sheet), approximately $40.1 million and approximately $189.6 million, respectively.

Our  accounting  policy  is  to  consolidate  entities  in  which  we  have  a  controlling  financial  interest  and  significant  decision  making  control  over  the  entity's
operations. In determining whether we have a controlling financial interest in a partially owned entity and the requirement to consolidate the accounts of that entity,
we  consider  factors  such  as  ownership  interest,  board  representation,  management  representation,  size  of  our  investment  (including  loans),  authority  to  control
decisions, and contractual and substantive participating rights of the members. In addition to evaluating control rights, we consolidate entities in which the other
members have no substantive kick-out rights to remove the Company as the managing member.

Entities in which the equity investors do not have sufficient equity at risk to finance their endeavors without additional financial support or the holders of the
equity investment at risk do not have a controlling financial interest are VIEs. We evaluate whether an entity is a VIE and whether we are the primary beneficiary.
We  are  deemed  to  be  the  primary  beneficiary  of  a  VIE  when  we  have  the  power  to  direct  the  activities  of  the  VIE  that  most  significantly  impact  the  VIEs’
economic performance and the obligation to absorb losses or receive benefits that could potentially be significant to the VIE.

If the requirements for consolidation are not met, the Company would account for investments under the equity method of accounting if we have the ability to
exercise significant influence over the entity. Equity method investments would be initially recorded at cost and subsequently adjusted for our share of net income
or loss and cash contributions and distributions each period. The Company did not have any equity method investments at December 31, 2020 or 2019.

Accounting Pronouncements Adopted January 1, 2020

ASU No. 2016-13 “Financial Instruments - Credit Losses (Topic 326)”

Effective January 1, 2020, we adopted Financial Accounting Standards Board (“FASB”) FASB Accounting Standards Update (“ASU”) No. 2016-13 (“ASU
2016-13”), which amends the accounting for credit losses for certain financial instruments. Under the new guidance, an entity recognizes its estimate of expected
credit losses as an allowance, which the FASB believes will result in more timely recognition of such losses.  In November 2018, the FASB released ASU No.
2018-19 “Codification Improvements to Topic 326, Financial Instruments - Credit Losses.” This ASU clarifies that receivables arising from operating leases are
not  within  the  scope  of  Subtopic  326-20  “Financial  Instruments  –  Credit  Losses.”  Instead,  impairment  of  receivables  arising  from  operating  leases  should  be
accounted  for  under  Subtopic  842-30  “Leases  –  Lessor.”  The  adoption  did  not  have  a  material  impact  on  our  consolidated  financial  statements  or  notes  to  our
consolidated financial statements.

ASU No. 2018-13 “Fair Value Measurement (Topic 820)”

Effective January 1, 2020, we adopted FASB ASU No. 2018-13 (“ASU 2018-13”), which amends the disclosure requirements for fair value measurements.
The amendments in ASU 2018-13 include new, modified and eliminated disclosure requirements and are the result of a broader disclosure project called FASB
Concepts Statement, Conceptual Framework for Financial  Reporting - Chapter 8: Notes to Financial Statements (the “Concepts Statement”), which the FASB
finalized on August 28, 2018. The FASB used the guidance in the Concepts Statement to improve the effectiveness of Topic 820’s disclosure requirements. The
adoption did not have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

ASU No. 2018-15 “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)”

Effective January 1, 2020, we adopted FASB ASU No. 2018-15 (“ASU 2018-15”), which amends a customer’s accounting for implementation costs incurred
in  a  cloud  computing  arrangement  that  is  a  service  contract.  ASU  2018-15  aligns  the  requirements  for  capitalizing  implementation  costs  incurred  in  a  hosting
arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting
arrangements that include an internal-use software license). The adoption did not have a material impact on our consolidated financial statements or notes to our
consolidated financial statements.

COVID-19 Lease Modification Accounting Relief

The global impact of the COVID-19 pandemic continues to evolve rapidly. Both of the states where we own properties and/or have development projects (i.e.,
California and Washington), have reacted to the COVID-19 pandemic by instituting quarantines, restrictions on travel, “shelter in place” rules, restrictions on types
of business that may continue to operate and/or restrictions on types of construction projects that may continue. These restrictions have impacted our business, as
well as that of our tenants.

Due to the business disruptions and challenges severely affecting the global economy caused by the COVID-19 pandemic, many lessors may be required to
provide  rent  deferrals  and  other  lease  concessions  to  lessees.  While  the  lease  modification  guidance  in  Accounting  Standards  Codification  (“ASC”)  Topic  842
(“Topic  842”)  addresses  routine  changes  to  lease  terms  resulting  from  negotiations  between  the  lessee  and  the  lessor,  this  guidance  did  not  contemplate
concessions being so rapidly executed to address the sudden liquidity constraints of some lessees arising from the COVID-19 pandemic and restrictions intended to
prevent its spread.

In  April  2020,  the  FASB  staff  issued  a  question  and  answer  document  (the  “Lease  Modification  Q&A”)  focused  on  the  application  of  lease  accounting
guidance to lease concessions provided as a result of the COVID-19 pandemic. Under existing lease guidance, the Company would have to determine, on a lease
by lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if
a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting
framework). The Lease Modification Q&A allows the Company, if certain criteria have been met, to bypass the lease by lease analysis, and instead elect to either
apply the lease modification accounting framework or not, with such election applied consistently to leases

F - 17

with similar characteristics and similar circumstances. The Company has elected to apply such relief and availed itself of the election to avoid performing a lease
by lease analysis. In addition, the Company has elected to apply the lease modification accounting framework consistently to leases within the property types in
which it invests, specifically office, life science, residential and retail properties.

Significant Accounting Policies

Revenue Recognition

Rental revenue for office, life science and retail operating properties is our principal source of revenue. We recognize revenue from base rent, additional rent
(which consists of amounts due from tenants for common area maintenance, real estate taxes, and other recoverable costs), parking and other lease-related revenue
once all of the following criteria are met: (i) the agreement has been fully executed and delivered, (ii) services have been rendered, (iii) the amount is fixed or
determinable and (iv) payment has been received or the collectability of the amount due is probable. Lease termination fees are amortized over the remaining lease
term, if applicable. If there is no remaining lease term, they are recognized when received and realized. Minimum annual rental revenues are recognized in rental
revenues on a straight-line basis over the non-cancellable term of the related lease.

Base Rent

The timing of when we commence rental revenue recognition for office, life science and retail properties depends largely on our conclusion as to whether the
Company or the tenant is the owner for accounting purposes of tenant improvements at the leased property. When we conclude that we are the owner of tenant
improvements for accounting purposes, we record the cost to construct the tenant improvements as an asset and commence rental revenue recognition when the
tenant takes possession of or controls the finished space, which is generally when tenant improvements being recorded as our assets are substantially complete. In
certain instances, when we conclude that the tenant is the owner of certain tenant improvements for accounting purposes, rental revenue recognition begins when
the tenant takes possession or controls the physical use of the leased space, which may occur in phases or for an entire building or project. The determination of
who owns the tenant improvements is made on a lease-by-lease basis and has a significant effect on the timing of commencement of revenue recognition.

When we conclude that the Company is the owner of tenant improvements for accounting purposes, we record the cost to construct the tenant improvements,
including  costs  paid  for  or  reimbursed  by  the  tenants,  as  a  capital  asset.  For  these  tenant-funded  tenant  improvements,  we  record  the  amount  funded  by  or
reimbursed by tenants as deferred revenue, which is amortized and recognized as rental income on a straight-line basis over the term of the related lease.

When  we  conclude  that  the  tenant  is  the  owner  of  certain  tenant  improvements  for  accounting  purposes,  we  record  our  contribution  towards  those  tenant-
owned improvements as a lease incentive, which is included in deferred leasing costs and acquisition-related intangible assets, net on our consolidated balance
sheets and amortized as a reduction to rental revenue on a straight-line basis over the term of the related lease.

For residential properties, we commence revenue recognition upon lease commencement. Residential rental revenue is recognized on a straight-line basis over

the term of the related lease, net of any concessions.

Additional Rent - Reimbursements from Tenants

Additional rent, consisting of amounts due from tenants for common area maintenance, real estate taxes and other recoverable costs, are recognized in rental
income in the period the recoverable costs are incurred. Prior to the adoption of Topic 842 on January 1, 2019, such amounts were recognized in revenue as tenant
reimbursements. Additional rent where we pay the associated costs directly to third-party vendors and are reimbursed by our tenants are recognized and recorded
on a gross basis, with the corresponding expense recognized in property expenses or real estate taxes. Prior to the adoption of Topic 842, recoverable costs were
generally recognized and recorded on a gross basis when we were the primary obligor with respect to purchasing goods and services from third-party suppliers, had
discretion in selecting the supplier, and had credit risk.

F - 18

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Other Property Income

Other property income primarily includes amounts recorded in connection with transient daily parking, tenant bankruptcy settlement payments, broken deal
income and property damage settlement related payments. Other property income also includes miscellaneous income from tenants, restoration fees and fees for
late rental payments. Amounts recorded within other property income fall within the scope of Topic 606 and are recognized as revenue at the point in time when
control of the goods or services transfers to the customer and our performance obligation is satisfied. Prior to the adoption of Topic 842 on January 1, 2019, other
property  income  primarily  included  amounts  recorded  in  connection  with  lease  terminations,  tenant  bankruptcy  settlement  payments,  broken  deal  income  and
property damage settlement payments.

Uncollectible Lease Receivables and Allowances for Tenant and Deferred Rent Receivables

We carry our current and deferred rent receivables net of allowances for amounts that may not be collected. Prior to the adoption of Topic 842 on January 1,
2019, the allowances were increased or decreased through provision for bad debts on our consolidated statements of operations. Upon the adoption of Topic 842 on
January 1, 2019, the allowances are increased or decreased through rental income, and our determination of the adequacy of the Company’s allowances for tenant
receivables includes a binary assessment of whether or not substantially all of the amounts due under a tenant’s lease agreement are probable of collection. Such
assessment involves using a methodology that incorporates a specific identification analysis and an aging analysis and considers the current economic and business
environment.  This  determination  requires  significant  judgment  and  estimates  about  matters  that  are  uncertain  at  the  time  the  estimates  are  made,  including  the
creditworthiness of specific tenants, specific industry trends and conditions, and general economic trends and conditions. 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 which would be recognized on a straight-line basis or (ii) cash that has been received from the tenant, including deferred revenue,
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.

For tenant and deferred rent receivables associated with leases whose rents are deemed probable of collection under Topic 842, we may record an allowance
under other authoritative GAAP using a methodology that incorporates a specific identification analysis and an aging analysis and considers the current economic
and  business  environment.  This  determination  requires  significant  judgment  and  estimates  about  matters  that  are  uncertain  at  the  time  the  estimates  are  made,
including the creditworthiness of specific tenants, specific industry trends and conditions, and general economic trends and conditions. Tenant and deferred rent
receivables deemed probable of collection are carried net of allowances for uncollectible accounts, with increases or decreases in the allowances recorded through
rental income on our consolidated statements of operations. Prior to the adoption of Topic 842 on January 1, 2019, the allowances were increased or decreased
through provision for bad debts on our consolidated statements of operations.

Current  tenant  receivables  consist  primarily  of  amounts  due  for  contractual  lease  payments  and  reimbursements  of  common  area  maintenance  expenses,
property taxes, and other costs recoverable from tenants. With respect to the allowance for uncollectible tenant receivables, the specific identification methodology
analysis relies on factors such as the age and nature of the receivables, the payment history and financial condition of the tenant, our assessment of the tenant’s
ability to meet its lease obligations, and the status of negotiations of any disputes with the tenant.

Deferred rent receivables represent the amount by which the cumulative straight-line rental revenue recorded to date exceeds cash rents billed to date under the
lease  agreement.  With  respect  to  the  allowance  for  deferred  rent  receivables,  given  the  longer-term  nature  of  these  receivables,  the  specific  identification
methodology  analysis  evaluates  each  of  our  significant  tenants  and  any  tenants  on  our  internal  watchlist  and  relies  on  factors  such  as  each  tenant’s  financial
condition  and  its  ability  to  meet  its  lease  obligations.  We  evaluate  our  reserve  levels  quarterly  based  on  changes  in  the  financial  condition  of  tenants  and  our
assessment of the tenant’s ability to meet its lease obligations, overall economic conditions, and the current business environment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Acquisitions

Acquisitions of operating properties and development and redevelopment opportunities generally do not meet the definition of a business and are accounted
for  as  asset  acquisitions,  as  substantially  all  of  the  fair  value  of  the  gross  assets  acquired  is  concentrated  in  a  single  identifiable  asset  or  a  group  of  similar
identifiable assets. For these asset acquisitions, we record the acquired tangible and intangible assets and assumed liabilities based on each asset’s and liability’s
relative fair value at the acquisition date of the total purchase price plus any capitalized acquisition costs. We record the acquired tangible and intangible assets and
assumed liabilities of acquisitions of operating properties and development and redevelopment opportunities that meet the accounting criteria to be accounted for
as business combinations at fair value at the acquisition date. Transaction costs associated with asset acquisitions, including costs incurred during negotiation, are
capitalized in addition to the purchase price of the acquisition.

The acquired assets and assumed liabilities for an acquisition generally include but are not limited to (i) land and improvements, buildings and improvements,
undeveloped  land  and  construction  in  progress  and  (ii)  identified  tangible  and  intangible  assets  and  liabilities  associated  with  in-place  leases,  including  tenant
improvements, leasing costs, value of above-market and below-market operating leases and ground leases, acquired in-place lease values and tenant relationships,
if any. Any debt assumed and equity (including common units of the Operating Partnership) issued in connection with a property acquisition is recorded at fair
value on the date of acquisition.

The fair value of land and improvements is derived from comparable sales of land and improvements within the same submarket and/or region. The fair value
of buildings and improvements, tenant improvements and leasing costs considers the value of the property as if it was vacant as well as current replacement costs
and other relevant market rate information.

The fair value of the above-market or below-market component of an acquired in-place operating lease is based upon the present value (calculated using a
market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining non-cancellable lease term and (ii) our
estimate of the rents that would be paid using fair market rental rates and rent escalations at the date of acquisition measured over the remaining non-cancellable
term of the lease for above-market operating leases and the initial non-cancellable term plus the term of any below-market fixed rate renewal options, if applicable,
for below-market operating leases. Our below-market operating leases generally do not include fixed rate or below-market renewal options. The amounts recorded
for above-market operating leases are included in deferred leasing costs and acquisition-related intangible assets, net on the balance sheet and are amortized on a
straight-line basis as a reduction of rental income over the remaining term of the applicable leases. The amounts recorded for below-market operating leases are
included in deferred revenue and acquisition-related intangible liabilities, net on the balance sheet and are amortized on a straight-line basis as an increase to rental
income over the remaining term of the applicable leases plus the term of any below-market fixed rate renewal options, if applicable. The amortization of a below-
market  ground  lease  obligation  is  recorded  as  an  increase  to  ground  lease  expense  in  the  consolidated  statements  of  operations  for  the  periods  presented.  The
amortization  of an above-market  ground lease obligation is recorded as a decrease to ground lease expense in the consolidated statements of operations for the
periods presented.

The fair value of acquired in-place leases is derived based on our assessment of lost revenue and costs incurred for the period required to lease the “assumed
vacant” property to the occupancy level when purchased. The amount recorded for acquired in-place leases is included in deferred leasing costs and acquisition-
related intangible assets, net on the balance sheet and amortized as an increase to depreciation and amortization expense over the remaining term of the applicable
leases. Fully amortized intangible assets are written off each quarter.

Operating Properties

Operating properties are generally carried at historical cost less accumulated depreciation. Properties held for sale are reported at the lower of the carrying
value or the fair value less estimated cost to sell. The cost of operating properties includes the purchase price or development costs of the properties. Costs incurred
for the renovation and betterment of the operating properties are capitalized to our investment in that property. Maintenance and repairs are charged to expense as
incurred.

When  evaluating  properties  to  be  held  and  used  for  potential  impairment,  we  first  evaluate  whether  there  are  any  indicators  of  impairment  for  any  of  our
properties.  If  any  impairment  indicators  are  present  for  a  specific  property,  we  then  evaluate  the  regional  market  conditions  that  could  reasonably  affect  the
property.  If  there  are  negative  changes  and  trends  in  that  regional  market,  we  then  perform  an  undiscounted  cash  flow  analysis  and  compare  the  net  carrying
amount of the property to the property’s estimated undiscounted future cash flow over the anticipated holding period. If the estimated undiscounted future cash
flow is less than the net carrying amount of the property, we perform an impairment loss calculation to determine if the fair value of the property is less than the net
carrying value of the property. Our impairment loss calculation compares the net carrying amount of the property to the property’s estimated fair value, which may
be based on estimated discounted future cash flow calculations or third-party valuations or appraisals. We would recognize an impairment loss if the property's net
carrying amount exceeds the property's estimated fair value. If we were to recognize an impairment loss, the estimated fair value of the property becomes its new
cost basis. For a depreciable long-lived asset, the new cost basis would be depreciated (amortized) over the remaining useful life of that asset.

Cost Capitalization

All  costs  clearly  associated  with  the  development,  redevelopment  and  construction  of  a  property  are  capitalized  as  project  costs,  including  internal
compensation  costs.  In  addition,  the  following  costs  are  capitalized  as  project  costs  during  periods  in  which  activities  necessary  to  prepare  development  and
redevelopment properties for their intended use are in progress: pre-construction costs essential to the development of the property, interest, real estate taxes and
insurance.

•

•

•

•

For  office,  life  science  and  retail  development  and  redevelopment  properties  that  are  pre-leased,  we  cease  capitalization  when  revenue  recognition
commences, which is upon substantial completion of tenant improvements deemed to be the Company’s asset for accounting purposes.

For  office,  life  science  and  retail  development  and  redevelopment  properties  that  are  not  pre-leased,  we  may  not  immediately  build  out  the  tenant
improvements. Therefore, we cease capitalization when revenue recognition commences upon substantial completion of the tenant improvements deemed
to be the Company's asset for accounting purposes, but in any event, no later than one year after the cessation of major construction activities. We also
cease  capitalization  on  a  development  or  redevelopment  property  when  activities  necessary  to  prepare  the  property  for  its  intended  use  have  been
suspended.

For office, life science and retail development or redevelopment properties with multiple tenants and phased leasing, we cease capitalization and begin
depreciation on the portion of the development or redevelopment property for which revenue recognition has commenced.

For residential development properties, we cease capitalization when the property is substantially complete and available for occupancy.

Once major base building construction activities have ceased and the development or redevelopment property or phases of the development or redevelopment
project is placed in service, which may occur in phases or for an entire building or project, the costs capitalized to construction in progress 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.

Depreciation and Amortization of Buildings and Improvements

The costs of buildings and improvements and tenant improvements are depreciated using the straight-line method of accounting over the estimated useful lives
set  forth  in  the  table  below.  Depreciation  expense  for  buildings  and  improvements  for  the  three  years  ended  December  31,  2020,  2019,  and  2018  was  $244.8
million, $211.9 million, and $198.6 million, respectively.

Real Estate Assets Held for Sale, Dispositions and Discontinued Operations

Depreciable Lives
25 – 40 years
1 – 20 years 
(1)

A real estate asset is classified as held for sale when certain criteria are met, including but not limited to the availability of the asset for immediate sale, the
existence of an active program to locate a buyer and the probable sale or transfer of the asset within one year. If such criteria are met, we present the applicable
assets  and  liabilities  related  to  the  real  estate  asset,  if  material,  separately  on  the  balance  sheet  as  held  for  sale  and  we  would cease  to  record  depreciation  and
amortization expense. Real estate assets held for sale are reported at the lower of their carrying value or their estimated fair value less the estimated costs to sell. As
of December 31, 2020 and 2019, we did not have any properties classified as held for sale.

Property disposals representing a strategic shift that have (or will have) a major effect on the Company’s operations and financial results, such as a major line
of  business,  a  major  geographical  area  or  a  major  equity  investment,  are  required  to  be  presented  as  discontinued  operations.  If  we  were  to  determine  that  a
property  disposition  represents  a  strategic  shift,  the  revenues,  expenses  and  net  gain  (loss)  on  dispositions  of  the  property  would  be  recorded  in  discontinued
operations for all periods presented through the date of the applicable disposition. The operations of the properties sold during the years ended December 31, 2020,
2019 and 2018 are presented in continuing operations as they did not represent a strategic shift in the Company’s operations and financial results.

The net gains (losses) on dispositions of non-depreciable real estate property, including land, are reported in the consolidated statements of operations as gains
(losses) on sale of land within continuing operations in the period the land is sold. The net gains (losses) on dispositions of depreciable real estate property are
reported in the consolidated statements of operations as gains on sales of depreciable operating properties within continuing operations in the period the property is
sold.

Cash and Cash Equivalents

We consider all highly-liquid investments with original maturities of three months or less to be cash equivalents.

Restricted Cash

Restricted  cash  consists  of  cash  proceeds  from  dispositions  that  are  temporarily  held  at  qualified  intermediaries  for  purposes  of  facilitating  potential
Section 1031 Exchanges and cash held in escrow related to acquisition and disposition holdbacks. Restricted cash also includes cash held as collateral to provide
credit enhancement for the Operating Partnership’s mortgage debt, including cash reserves for capital expenditures, tenant improvements and property taxes. As of
December 31, 2020, we had $74.9 million of restricted cash held at qualified intermediaries  for the purpose of facilitating  Section 1031 Exchanges. In January
2021, the Section 1031 Exchange was terminated and the cash proceeds were released from the qualified intermediary. We did not have any restricted cash held at
qualified intermediaries for the purpose of facilitating Section 1031 Exchanges at December 31, 2019.

Marketable Securities / Deferred Compensation Plan

Marketable securities reported in our consolidated balance sheets represent the assets held in connection with the Kilroy Realty Corporation 2007 Deferred
Compensation  Plan  (the  “Deferred  Compensation  Plan”)  (see  Note  16  “Employee  Benefit  Plans”  for  additional  information).  The  Deferred  Compensation  Plan
assets are held in a limited rabbi trust and invested in various mutual and money market funds. As a result, the marketable securities are treated as trading securities
for financial reporting purposes and are adjusted to fair value at the end of each accounting period, with the corresponding gains and losses recorded in interest
income and other net investment gains (losses).

At  the  time  eligible  management  employees  (“Participants”)  defer  compensation  or  earn  mandatory  Company  contributions,  or  if  we  were  to  make  a
discretionary contribution, we record compensation cost and a corresponding deferred compensation plan liability, which is included in accounts payable, accrued
expenses,  and  other  liabilities  on  our  consolidated  balance  sheets.  This  liability  is  adjusted  to  fair  value  at  the  end  of  each  accounting  period  based  on  the
performance of the benchmark funds selected by each Participant, and the impact of adjusting the liability to fair value is recorded as an increase or decrease to
compensation cost. The impact of adjusting the deferred compensation plan liability to fair value and the changes in the value of the marketable securities held in
connection with the Deferred Compensation Plan generally offset and therefore do not significantly impact net income.

Deferred Leasing Costs

Costs incurred in connection with successful property leasing are capitalized as deferred leasing costs and classified as investing activities in the statement of
cash flows. Under Topic 842, initial direct costs include only those costs that are incremental to the arrangement and would not have been incurred if the lease had
not been obtained. As a result, subsequent to the adoption of Topic 842 on January 1, 2019, deferred leasing costs consist of leasing commissions paid to external
third party brokers and lease incentives, and the Company no longer capitalizes internal leasing costs and third-party legal leasing costs. Prior to the adoption of
Topic 842, deferred leasing costs consisted primarily of leasing commissions, lease incentives, legal costs and certain internal payroll costs. Deferred leasing costs
are  amortized  using  the  straight-line  method  of  accounting  over  the  lives  of  the  leases  which  generally  range  from  one to  20  years.  We  may  reevaluate  the
remaining  useful  lives  of  leasing  costs  as  the  creditworthiness  of  our  tenants  and  economic  and  market  conditions  change.  If  we  determine  that  the  estimated
remaining life of a lease has changed, we adjust the amortization period accordingly. Fully amortized deferred leasing costs are written off each quarter.

Deferred Financing Costs

Financing costs related to the origination or assumption of long-term debt are deferred and generally amortized using the straight-line method of accounting,
which approximates the effective interest method, over the contractual terms of the applicable financings. Fully amortized deferred financing costs are written off
when the corresponding financing is repaid.

Debt Discounts and Premiums

Original issuance debt discounts and discounts/premiums related to recording debt acquired in connection with operating property acquisitions at fair value are
generally amortized and accreted on a straight-line basis, which approximates the effective interest method. Discounts are recorded as additional interest expense
from date of issuance or acquisition through the contractual maturity date of the related debt. Premiums are recorded as a reduction to interest expense from the
date of issuance or acquisition through the contractual maturity date of the related debt.

Noncontrolling Interests - Common Units of the Operating Partnership in the Company's Consolidated Financial Statements

Common units of the Operating Partnership within noncontrolling interests in the Company’s consolidated financial statements represent the common limited
partnership interests in the Operating Partnership not held by the Company (“noncontrolling common units”). Noncontrolling common units are presented in the
equity section of the

F - 23

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Company’s consolidated balance sheets and are reported at their proportionate share of the net assets of the Operating Partnership. Noncontrolling interests with
redemption provisions that permit the issuer to settle in either cash or shares of common stock must be further evaluated to determine whether equity or temporary
equity classification on the balance sheet is appropriate. Since the common units contain such a provision, we evaluated the accounting guidance and determined
that the common units qualify for equity presentation in the Company’s consolidated financial statements. Net income attributable to noncontrolling common units
is allocated based on their relative ownership percentage of the Operating Partnership during the reported period. The noncontrolling interest ownership percentage
is determined by dividing the number of noncontrolling common units by the total number of common units outstanding. The issuance or redemption of additional
shares of common stock or common units results in changes to the noncontrolling interest percentage as well as the total net assets of the Company. As a result, all
equity transactions result in an allocation between equity and the noncontrolling interest in the Company’s consolidated balance sheets and statements of equity to
account for the changes in the noncontrolling interest ownership percentage as well as the change in total net assets of the Company.

Noncontrolling Interests in Consolidated Property Partnerships

Noncontrolling interests in consolidated property partnerships represent the equity interests held by unrelated third parties in our three consolidated property
partnerships  (see  Note  11  “Noncontrolling  Interests  on  the  Company’s  Consolidated  Financial  Statements”  and  see  Note  12  “Noncontrolling  Interests  on  the
Operating Partnership’s Consolidated Financial Statements”). Noncontrolling interests in consolidated property partnerships are not redeemable and are presented
as  permanent  equity  in  the  Company's  consolidated  balance  sheets.  We  account  for  the  noncontrolling  interests  in  consolidated  property  partnerships  using  the
hypothetical liquidation at book value (“HLBV”) method to attribute the earnings or losses of the consolidated property partnerships between the controlling and
noncontrolling  interests.  Under  the  HLBV  method,  the  amounts  reported  as  noncontrolling  interests  in  consolidated  property  partnerships  in  the  consolidated
balance sheets represent the amounts the noncontrolling interests would hypothetically receive at each balance sheet reporting date under the liquidation provisions
of the governing agreements assuming the net assets of the consolidated property partnerships were liquidated at recorded amounts and distributed between the
controlling  and  noncontrolling  interests  in  accordance  with  the  governing  documents.  The  net  income  attributable  to  noncontrolling  interests  in  consolidated
property  partnerships  in  the  consolidated  statements  of  operations  is  associated  with  the  increase  or  decrease  in  the  noncontrolling  interest  holders’  contractual
claims on the respective entities’ balance sheets assuming a hypothetical liquidation at the end of that reporting period when compared with their claims on the
respective entities’ balance sheets assuming a hypothetical liquidation at the beginning of that reporting period, after removing any contributions or distributions.

Common Partnership Interests on the Operating Partnership’s Consolidated Balance Sheets

The  common  units  held  by  the  Company  and  the  noncontrolling  common  units  held  by  the  common  limited  partners  are  both  presented  in  the  permanent
equity section of the Operating Partnership’s consolidated balance sheets in partners’ capital. The redemption rights of the noncontrolling common units permit us
to settle the redemption obligation in either cash or shares of the Company’s common stock at our option (see Note 11 “Noncontrolling Interests on the Company’s
Consolidated Financial Statements” for additional information).

Noncontrolling Interests on the Operating Partnership’s Consolidated Financial Statements

Noncontrolling  interests  in  the  Operating  Partnership’s  consolidated  financial  statements  include  the  noncontrolling  interest  in  property  partnerships  (see
Note 12 “Noncontrolling Interests on the Operating Partnership’s Consolidated Financial Statements”). As of December 31, 2019, noncontrolling interests in the
Operating Partnership’s consolidated financial statements also included the Company’s 1.0% general partnership interest in Kilroy Realty Finance Partnership, L.P.
in the permanent equity section of the Operating Partnership’s consolidated balance sheets given that these interests were not convertible or redeemable into any
other ownership interest of the Company or the Operating Partnership.

Equity Offerings

Underwriting commissions and offering costs incurred in connection with common equity offerings and our at-the-market stock offering program (see Note 13
“Stockholders’  Equity  of  the  Company”)  are  reflected  as  a  reduction  of  additional  paid-in  capital.  Issuance  costs  incurred  in  connection  with  preferred  equity
offerings are reflected as a reduction of the carrying value of the preferred equity.

Sales of our common stock under forward equity sale agreements (such as those under the forward equity offering entered into in February 2020 and those
under  the  2018  At-The-Market  Program,  as  discussed  in  Note  13  “Stockholders’  Equity  of  the  Company”)  meet  the  derivatives  and  hedging  guidance  scope
exception  to  be  accounted  for  as  equity  instruments  based  on  the  following  assessment:  (i)  none  of  the  agreements’  exercise  contingencies  were  based  on
observable markets or indices besides those related to the market for our own stock price and operations; and (ii) none of the settlement provisions precluded the
agreements from being indexed to our own stock.

The net proceeds from any equity offering of the Company are generally contributed to the Operating Partnership in exchange for a number of common units
equivalent  to the number of shares of common  stock issued and are reflected  in the Operating  Partnership’s  consolidated  financial  statements  as an increase  in
partners’ capital.

Share-based Incentive Compensation Accounting

Compensation  cost  for  all  share-based  awards,  including  options,  requires  measurement  at  estimated  fair  value  on  the  grant  date.  Compensation  cost  is
recognized on a straight-line basis over the service vesting period, which represents the requisite service period. The grant date fair value of market measure-based
share-based compensation plans are calculated using a Monte Carlo simulation pricing model. The grant date fair value of stock option grants is calculated using
the Black-Scholes valuation model. Equity awards settled in cash are valued at the fair value of our common stock on the period end date through the settlement
date. Equity awards settled in cash are remeasured at each reporting period and are recognized as a liability in the consolidated balance sheet during the vesting
period until settlement. Forfeitures of all share-based awards are recognized when they occur.

For share-based awards in which the performance  period precedes  the grant date, we recognize  compensation cost over the requisite  service period, which
includes both the performance and service vesting periods, using the accelerated attribution expense method. The requisite service period begins on the date the
Executive Compensation Committee authorizes the award and adopts any relevant performance measures.

For  share-based  awards  with  performance-based  measures,  the  total  estimated  compensation  cost  is  based  on  our  most  recent  estimate  of  the  probable
achievement of the pre-established specific corporate performance measures. These estimates are based on actual results and our latest internal forecasts for each
performance measure. For share-based awards with market measures, the total estimated compensation cost is based on the fair value of the award at the grant date.
For share-based awards with performance-based measures and market measures, the total estimated compensation cost is based on the fair value per share at the
grant date multiplied by our most recent estimate of the number of shares to be earned based on actual results and the probable achievement of the pre-established
corporate performance measures based on our latest internal forecasts.

In accordance with the provisions of our share-based incentive compensation plan, we accept the return of shares of Company common stock, at the current

quoted market price, from employees to satisfy minimum statutory tax-withholding requirements related to shares that vested during the period.

For share-based awards granted by the Company, the Operating Partnership issues a number of common units equal to the number of shares of common stock

ultimately granted by the Company in respect of such awards.

Basic and Diluted Net Income Available to Common Stockholders per Share

Basic  net  income  available  to  common  stockholders  per  share  is  computed  by  dividing  net  income  available  to  common  stockholders,  after  preferred

distributions and the allocation of income to participating securities, by the

F - 25

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

weighted-average number of shares of common stock outstanding for the period. Diluted net income available to common stockholders per share is computed by
dividing  net  income  available  for  common  stockholders,  after  preferred  distributions  and  the  allocation  of  income  to  participating  securities,  by the  sum  of  the
weighted-average number of shares of common stock outstanding for the period plus the assumed exercise of all dilutive securities. The impact of the outstanding
common units is considered in the calculation of diluted net income available to common stockholders per share. The common units are not reflected in the diluted
net income available to common stockholders per share calculation because the exchange of common units into common stock is on a one for one basis, and the
common units are allocated net income on a per share basis equal to the common stock (see Note 21 “Net Income Available to Common Stockholders Per Share of
the Company”). Accordingly, any exchange would not have any effect on diluted net income (loss) available to common stockholders per share.

Nonvested share-based payment awards (including nonvested restricted stock units (“RSUs”), vested market-measure RSUs and vested dividend equivalents
issued to holders of RSUs) containing nonforfeitable rights to dividends or dividend equivalents are accounted for as participating securities and included in the
computation of basic and diluted net income available to common stockholders per share pursuant to the two-class method. The dilutive effect of shares issuable
under executed forward equity sale agreements, if any, and stock options are reflected in the weighted average diluted outstanding shares calculation by application
of  the  treasury  stock  method.  The  dilutive  effect  of  the  outstanding  nonvested  shares  of  common  stock  (“nonvested  shares”)  and  RSUs  that  have  not  yet  been
granted but are contingently issuable under the share-based compensation programs is reflected in the weighted average diluted shares calculation by application of
the treasury stock method at the beginning of the quarterly period in which all necessary conditions have been satisfied.

Basic and Diluted Net Income Available to Common Unitholders per Unit

Basic net income available to common unitholders per unit is computed by dividing net income available to common unitholders, after preferred distributions
and the allocation of income to participating securities, by the weighted-average number of vested common units outstanding for the period. Diluted net income
available to common unitholders per unit is computed by dividing net income available to common unitholders, after preferred distributions and the allocation of
income to participating securities, by the sum of the weighted-average number of common units outstanding for the period plus the assumed exercise of all dilutive
securities.

The dilutive effect of stock options, outstanding nonvested shares, RSUs, awards containing nonforfeitable rights to dividend equivalents and shares issuable
under executed forward equity sale agreements, if any, are reflected in diluted net income available to common unitholders per unit in the same manner as noted
above for net income available to common stockholders per share.

Fair Value Measurements

The  fair  values  of  our  financial  assets  and  liabilities  are  disclosed  in  Note  19,  “Fair  Value  Measurements  and  Disclosures,”  to  our  consolidated  financial
statements. The only financial assets recorded at fair value on a recurring basis in our consolidated financial statements are our marketable securities. We elected
not to apply the fair value option for any of our eligible financial instruments or other items.

We determine the estimated fair value of financial assets and liabilities utilizing a hierarchy of valuation techniques based on whether the inputs to a fair value
measurement are considered to be observable or unobservable in a marketplace. Observable inputs reflect market data obtained from independent sources, while
unobservable  inputs  reflect  our  market  assumptions.  This  hierarchy  requires  the  use  of  observable  market  data  when  available.  The  following  is  the  fair  value
hierarchy:

•

•

Level 1 – quoted prices for identical instruments in active markets;

Level  2  –  quoted  prices  for  similar  instruments  in  active  markets;  quoted  prices  for  identical  or  similar  instruments  in  markets  that  are  not  active  and
model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and

F - 26

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

•

Level  3  –  fair  value  measurements  derived  from  valuation  techniques  in  which  one  or  more  significant  inputs  or  significant  value  drivers  are
unobservable.

We determine the fair value for the marketable securities using quoted prices in active markets for identical assets. Our other financial instruments, which are

only disclosed at fair value, are comprised of secured debt, unsecured senior notes, unsecured line of credit and unsecured term loan facility.

We generally determine the fair value of our secured debt, unsecured debt, unsecured line of credit and unsecured term loan facility, prior to its repayment in
August  2020,  by  performing  discounted  cash  flow  analyses  using  an  appropriate  market  discount  rate.  We  calculate  the  market  rate  by  obtaining  period-end
treasury rates for maturities that correspond to the maturities of our fixed-rate debt and then adding an appropriate credit spread based on information obtained
from  third-party  financial  institutions.  These  credit  spreads  take  into  account  factors,  including  but  not  limited  to,  our  credit  profile,  the  tenure  of  the  debt,
amortization period, whether the debt is secured or unsecured, and the loan-to-value ratio of the debt to the collateral. These calculations are significantly affected
by the assumptions used, including the discount rate, credit spreads and estimates of future cash flow. We calculate the market rate of our unsecured line of credit
and unsecured term loan facility by obtaining the period-end London Interbank Offered Rate (“LIBOR”) and then adding an appropriate credit spread based on our
credit  ratings,  and  the  amended  terms  of  our  unsecured  line  of  credit  and  unsecured  term  loan  facility  agreement.  We  determine  the  fair  value  of  each  of  our
publicly traded unsecured senior notes based on their quoted trading price at the end of the reporting period, if such prices are available.

Carrying amounts of our cash and cash equivalents, restricted cash and accounts payable approximate fair value due to their short-term maturities.

Income Taxes

We have elected to be taxed as a REIT under Sections 856 through 860 of the Code. To qualify as a REIT, we must distribute annually at least 90% of our
adjusted taxable income, as defined in the Code, to our stockholders and satisfy certain other organizational and operating requirements. We generally will not be
subject to federal income taxes if we distribute 100% of our taxable income for each year to our stockholders. If we fail to qualify as a REIT in any taxable year,
we will be subject to federal income taxes on our taxable income at regular corporate rates and we may not be able to qualify as a REIT for four subsequent taxable
years. Even if we qualify for taxation as a REIT, we may be subject to certain state and local taxes on our income and property and to federal income taxes and
excise  taxes  on  our  undistributed  taxable  income.  We  believe  that  we  have  met  all  of  the  REIT  distribution  and  technical  requirements  for  the  years  ended
December  31,  2020,  2019  and  2018,  and  we  were  not  subject  to  any  federal  income  taxes  (see  Note  25  “Tax  Treatment  of  Distributions”  for  additional
information).  We intend to continue to adhere to these requirements  and maintain the Company’s REIT status. Accordingly, no provision for income taxes has
been made in the accompanying financial statements.

In addition, any taxable income from our taxable REIT subsidiaries, which were formed in 2002, 2018, 2019 and 2020, are subject to federal, state, and local

income taxes. For the years ended December 31, 2020, 2019 and 2018 the taxable REIT subsidiaries had de minimis taxable income.

Uncertain Tax Positions

We include favorable tax positions in the calculation of tax liabilities if it is more likely than not that our adopted tax position will prevail if challenged by tax

authorities.

We  evaluated  the  potential  impact  of  identified  uncertain  tax  positions  for  all  tax  years  still  subject  to  audit  under  state  and  federal  income  tax  law  and
concluded that we did not have any unrecognized tax benefits or any additional tax liabilities as of December 31, 2020 or 2019. As of December 31, 2020, the
years still subject to audit are 2016 through 2020 under the California state income tax law and 2017 through 2020 under the federal income tax law.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the
reported periods. Actual results could differ from those estimates.

Segments

We currently operate in one operating segment, our office and life science properties segment.

Concentration of Credit Risk

All of our properties and development and redevelopment projects are owned and all of our business is currently conducted in the state of California with the
exception of the ownership and operation of eight office properties, one development project in the tenant improvement phase and one future development project
located in the state of Washington. The ability of tenants to honor the terms of their leases is dependent upon the economic, regulatory, and social factors affecting
the communities in which our tenants operate.

We have deposited cash with financial institutions that is insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 per institution. As of

December 31, 2020 and 2019, we had cash accounts in excess of FDIC insured limits.

8.    Secured and Unsecured Debt of the Company

In  this  Note  8,  the  “Company”  refers  solely  to  Kilroy  Realty  Corporation  and  not  to  any  of  our  subsidiaries.  The  Company  itself  does  not  hold  any

indebtedness. All of our secured and unsecured debt is held directly by the Operating Partnership.

The Company generally guarantees all the Operating Partnership’s unsecured debt obligations including the unsecured revolving credit facility, the unsecured
term loan facility and all of the unsecured senior notes. At December 31, 2020 and 2019, the Operating Partnership had $3.7 billion and $3.3 billion, respectively,
outstanding in total, including unamortized discounts and deferred financing costs, under these unsecured debt obligations.

In addition, although the remaining $0.3 billion of the Operating Partnership’s debt as of December 31, 2020 and 2019, is secured and non-recourse to the
Company,  the  Company  provides  limited  customary  secured  debt  guarantees  for  items  such  as  voluntary  bankruptcy,  fraud,  misapplication  of  payments  and
environmental liabilities.

Debt Covenants and Restrictions

One  of  the  covenants  contained  within  the  unsecured  revolving  credit  facility  as  discussed  further  below  in  Note  9  prohibits  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.

The Operating Partnership’s secured debt was collateralized by operating properties with a combined net book value of approximately $222.0 million as of

December 31, 2020.

Although our mortgage loans are secured and non-recourse to the Company and the Operating Partnership, the Company provides limited customary secured

debt guarantees for items such as voluntary bankruptcy, fraud, misapplication of payments and environmental liabilities.

As of December 31, 2020, all of the Operating Partnership’s secured loans contained restrictions that would require the payment of prepayment penalties for
the acceleration of outstanding debt. The mortgage notes payable are secured by deeds of trust on certain of our properties and the assignment of certain rents and
leases associated with those properties.

the terms of the unsecured revolving credit facility and unsecured term loan facility.

(2) Our unsecured revolving credit facility interest rate was calculated based on the contractual rate of LIBOR plus 1.000% as of December 31, 2020 and 2019.
(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
December 31, 2020 and 2019, $2.1 million and $3.4 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 maturity date of our unsecured revolving credit facility.

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

In August 2020, the Company repaid in full the $150.0 million unsecured term loan facility. The following table summarizes the balance and terms of our

Debt Covenants and Restrictions

The unsecured revolving credit facility, the unsecured senior notes, the Series A and B Notes due 2026, Series A and B Notes due 2027 and 2029, and Notes
due 2031 and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements.
Some of the more restrictive financial covenants include a maximum ratio of total debt to total asset value, a minimum fixed-charge coverage ratio, a minimum
unsecured  debt  ratio  and  a  minimum  unencumbered  asset  pool  debt  service  coverage  ratio.  Noncompliance  with  one  or  more  of  the  covenants  and  restrictions
could result in the full principal balance of the associated debt becoming immediately due and payable. We believe we were in compliance with all of our debt
covenants as of December 31, 2020 and 2019.

11.    Noncontrolling Interests on the Company’s Consolidated Financial Statements

Common Units of the Operating Partnership

The Company owned a 99.0% and 98.1% common general partnership interest in the Operating Partnership as of December 31, 2020 and 2019, respectively.
The remaining 1.0% and 1.9% common limited partnership interest as of December 31, 2020 and 2019, respectively, was owned by non-affiliated investors and
certain of our executive officers and directors in the form of noncontrolling common units. There were 1,150,574 and 2,023,287 common units outstanding held by
these investors, executive officers and directors as of December 31, 2020 and 2019, respectively. The decrease in the common units from December 31, 2019 to
December 31, 2020 was attributable to 872,713 common unit redemptions.

The  noncontrolling  common  units  may  be  redeemed  by  unitholders  for  cash.  Except  under  certain  circumstances,  we,  at  our  option,  may  satisfy  the  cash
redemption obligation with shares of the Company’s common stock on a one-for-one basis. If satisfied in cash, the value for each noncontrolling common unit
upon redemption is the amount equal to the average of the closing quoted price per share of the Company’s common stock, par value $.01 per share, as reported on
the  NYSE  for  the  ten  trading  days  immediately  preceding  the  applicable  redemption  date.  The  aggregate  value  upon  redemption  of  the  then-outstanding
noncontrolling common units was $65.4 million and $167.7 million as of December 31, 2020 and 2019, respectively. This redemption value does not necessarily
represent the amount that would be distributed with respect to each noncontrolling common unit in the event of our termination or liquidation. In the event of our
termination or liquidation, it is expected in most cases that each common unit would be entitled to a liquidating distribution equal to the liquidating distribution
payable in respect of each share of the Company’s common stock.

Noncontrolling Interest in Consolidated Property Partnerships

In  August  2016,  the  Operating  Partnership  entered  into  agreements  with  Norges  Bank  Real  Estate  Management  (“NBREM”)  whereby  NBREM  made
contributions, through two REIT subsidiaries, for a 44% common equity interest in two existing companies that owned the Company’s 100 First Street and 303
Second  Street  office  properties  located  in  San  Francisco,  California.  The  transactions  did  not  meet  the  criteria  to  qualify  as  sales  of  real  estate  because  the
Company continues to effectively control the properties and therefore continued to account for the 100 First Street and 303 Second Street office properties on a
consolidated  basis  in  its  financial  statements.  At  formation,  the  Company  accounted  for  the  transactions  as  equity  transactions  and  recognized  noncontrolling
interests in its consolidated balance sheets.

The noncontrolling interests in 100 First LLC and 303 Second LLC as of December 31, 2020 and 2019 were $191.9 million and $189.6 million, respectively.
The  remaining  amount  of  noncontrolling  interests  in  consolidated  property  partnerships  represents  the  third  party  equity  interest  in  Redwood  LLC.  This
noncontrolling interest was $5.6 million and $5.8 million as of December 31, 2020 and 2019, respectively.

of common stock that the Company has the authority to issue from 150,000,000 shares to 280,000,000 shares.

Forward Equity Offerings and Settlements

On February 18, 2020, the Company entered into forward equity sale agreements with certain financial institutions acting as forward purchasers in connection
with  an  offering  of  5,750,000  shares  of  common  stock  at  an  initial  gross  offering  price  of  $494.5  million,  or  $86.00  per  share,  before  underwriting  discounts,
commissions and offering expenses. The forward purchasers borrowed and sold an aggregate of 5,750,000 shares of common stock in the offering. The Company
did not receive any proceeds from the sale of its shares of common stock by the forward purchasers at the time of the offering.

On March 25, 2020, the Company physically settled these forward equity sale agreements. Upon settlement, the Company issued 5,750,000 shares of common
stock for net proceeds of $474.9 million and contributed the net proceeds to the Operating Partnership in exchange for an equal number of units in the Operating
Partnership.

In August 2018, the Company entered into forward equity sale agreements with certain financial institutions acting as forward purchasers in connection with
an  offering  of  5,000,000  shares  of  common  stock  at  an  initial  gross  offering  price  of  $360.5  million,  or  $72.10  per  share,  before  underwriting  discounts,
commissions and offering expenses. The forward purchasers borrowed and sold an aggregate of 5,000,000 shares of common stock in the offering. The Company
did not receive any proceeds from the sale of its shares of common stock by the forward purchasers at the time of the offering.

In July 2019, the Company physically settled these forward equity sale agreements. Upon settlement, the Company issued 5,000,000 shares of common stock
for  net  proceeds  of  $354.3  million  and  contributed  the  net  proceeds  to  the  Operating  Partnership  in  exchange  for  an  equal  number  of  units  in  the  Operating
Partnership.

At-The-Market Stock Offering Programs

Under our at-the-market stock offering programs, which commenced in December 2014 and June 2018, we may offer and sell shares of our common stock
from  time  to  time  in  “at-the-market”  offerings.  During  the  year  ended  December  31,  2018,  the  Company  completed  its  existing  at-the-market  stock  offering
program  (the  “2014  At-The-Market  Program”)  under  which  we  sold  an  aggregate  of  $300.0  million  in  gross  sales  of  shares.  In  June  2018,  the  Company
commenced a new at-the-market  stock offering program (the “2018 At-The-Market Program”) under which we may offer and sell shares of our common stock
with an aggregate gross sales price of up to $500.0 million. In connection with the 2018 At-The-Market Program, the Company may also, at its discretion, enter
into forward equity sale agreements. The use of forward equity sale agreements allows the Company to lock in a share price on the sale of shares of our common
stock at the time an agreement is executed, but defer settling the forward equity sale agreements and receiving the proceeds from the sale of shares until a later
date.

15.    Share-Based and Other Compensation

Stockholder Approved Share-Based Incentive Compensation Plan

As of December 31, 2020, we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan, as amended (the “2006
Plan”). The Company has a currently effective registration statement registering 10.7 million shares of our common stock for possible issuance under our 2006
Incentive  Award  Plan.  As  of  December  31,  2020,  approximately  1.5  million  shares  were  available  for  grant  under  the  2006  Plan.  The  calculation  of  shares
available for grant is presented after taking into account a reserve for a sufficient number of shares to cover the vesting and payment of 2006 Plan awards that were
outstanding on that date, including performance-based vesting awards at (i) levels actually achieved for the performance conditions (as defined below) for which
the performance period has been completed and (ii) at maximum levels for the other performance and market conditions (as defined below) for awards still in a
performance period.

The Executive Compensation Committee (the “Compensation Committee”) of the Company’s Board of Directors may grant the following share-based awards
to eligible individuals, as provided under the 2006 Plan: incentive stock options, nonqualified stock options, restricted stock (nonvested shares), stock appreciation
rights,  performance  shares,  performance  stock  units,  dividend  equivalents,  stock  payments,  deferred  stock,  restricted  stock  units  (“RSUs”),  profit  interest  units,
performance  bonus  awards,  performance-based  awards  and  other  incentive  awards.  For  each  award  granted  under  our  share-based  incentive  compensation
programs, the Operating Partnership simultaneously issues to the Company a number of common units equal to the number of shares of common stock ultimately
paid by the Company in respect of such awards.

In January and February 2018, the Executive Compensation Committee of the Company’s Board of Directors awarded 282,038 RSUs to certain officers of the
Company  under  the  2006  Plan,  which  included  158,205  RSUs (at  the  target  level  of  performance)  that  are  subject  to  market  and/or  performance-based  vesting
requirements  (the  “2018  Performance-Based  RSUs”)  and  123,833  RSUs  that  are  subject  to  time-based  vesting  requirements  (the  “2018  Time-Based  RSUs”).
Additionally, during 2018, 14,999 RSUs were granted to the board of directors and certain members of management subject to time vesting requirements.

    December 2018 Market-Based RSU Grant

Between 0% and 200% of the total 346,777 target number of December 2018 Market-Based RSUs will be eligible to vest based on the Company’s relative
total  shareholder  return  (“TSR”)  versus  a  comparative  group  of  companies  that  consist  of  companies  in  the  SNL  US  REIT  Office  Index  over  the  performance
period. An initial number of RSUs (the “Initial Number of RSUs”) will be determined at the end of 2021 based on a three year performance period (consisting of
calendar years 2019 through 2021). Once the Initial Number of RSUs is determined, 75% of the Initial Number of RSUs will be scheduled to vest on January 5,
2022. The remaining 25% of the Initial Number of RSUs will be scheduled to vest on January 5, 2023, subject to adjustment based on the Company’s relative TSR
for the entire four-year performance period (2019 through 2022). The December 2018 Market-Based RSUs are also subject to service vesting requirements through
the scheduled vest dates.

Each  December  2018  Market-Based  RSU  represents  the  right  to  receive  one  share  of  our  common  stock  in  the  future,  subject  to,  and  as  modified  by,  the
Company’s level of achievement of the applicable market conditions. The December 27, 2018 grant date fair value of the December 2018 Market-Based RSUs was
$23.8  million.  The  fair  value  was  calculated  using  a  Monte  Carlo  simulation  pricing  model  based  on  the  assumptions  in  the  table  below.  For  the  years  ended
December  31,  2020,  2019  and  2018,  we  recorded  compensation  expense  based  upon  the  $68.66  grant  date  fair  value  per  share.  Compensation  expense  for  the
December 2018 Market-Based RSUs is recognized using a graded vesting approach, where 75% of the fair value will be recognized on a straight-line basis over
the three-year initial performance period through the end of 2021, and the remaining 25% of the fair value will be recognized on a straight-line basis over the four-
year final performance period through the end of 2022. The following table summarizes the assumptions utilized in the Monte Carlo simulation pricing models:

Risk-free interest rate

The computation of expected volatility was based on a blend of the historical volatility of our shares of common stock over a period of twice the performance
period and implied volatility data based on the observed pricing of six month publicly-traded options on shares of our common stock. The risk-free interest rate
was based on the yield curve on zero-coupon U.S. Treasury STRIP securities in effect at December 27, 2018.

    2020, 2019 and 2018 Annual Performance-Based RSU Grants

The 2020 Performance-Based RSUs are scheduled to vest at the end of a three year period (consisting of calendar years 2020-2022). A target number of 2020
Performance-Based RSUs were awarded, and the final number of 2020 Performance-Based RSUs that vest (which may be more or less than the target number) will
be based upon (1) the achievement of pre-set FFO per share goals for the year ending December 31, 2020 that applies to 100% of the Performance-Based RSUs
awarded  (the  “2020  FFO  Performance  Condition”)  and  (2)  a  performance  measure  that  applies  to  50%  of  the  award  based  upon  a  measure  of  the  Company’s
average  debt  to  EBITDA  ratio  for  the  three  year  performance  period  (the  “2020  Debt  to  EBITDA  Ratio  Performance  Condition”)  and  a  market  measure  that
applies to the other 50% of the award based upon the relative ranking of the Company’s total stockholder return for the three year performance period compared to
the total stockholder returns of an established comparison group of companies over the same period (the “2020 Market Condition”). The 2020 Performance-Based
RSUs  are  also  subject  to  a  three  year  service  vesting  provision  (the  “service  vesting  condition”)  and  are  scheduled  to  cliff  vest  on  the  date  the  final  vesting
percentage is determined following the end of the three year performance period under the

awards.  The  2020  FFO  Performance  Condition  was  achieved  at  100%  of  target  for  all  participants.  The  number  of  2020  Performance-Based  RSUs  ultimately
earned  could  fluctuate  from  the  target  number  of  2020  Performance-Based  RSUs granted  based  upon  the  levels  of  achievement  for  the  2020  Debt  to  EBITDA
Ratio Performance Condition, the 2020 Market Condition, and the extent to which the service vesting condition is satisfied. The estimate of the number of 2020
Performance-Based  RSUs earned  is evaluated  quarterly  during  the  performance  period  based  on our  estimate  for  each  of the  performance  conditions  measured
against the applicable goals. Compensation expense for the 2020 Performance-Based RSU grant is recognized on a straight-line basis over the requisite service
period for each participant, which is generally the three year service period.

The 2019 Performance-Based RSUs are scheduled to vest at the end of a three year period (consisting of calendar years 2019-2021). A target number of 2019
Performance-Based RSUs were awarded, and the final number of 2019 Performance-Based RSUs that vest (which may be more or less than the target number) will
be based upon (1) the achievement of pre-set FFO per share goals for the year ending December 31, 2019 that applies to 100% of the Performance-Based RSUs
awarded  (the  “2019  FFO  Performance  Condition”)  and  (2)  a  performance  measure  that  applies  to  50%  of  the  award  based  upon  a  measure  of  the  Company’s
average  debt  to  EBITDA  ratio  for  the  three  year  performance  period  (the  “2019  Debt  to  EBITDA  Ratio  Performance  Condition”)  and  a  market  measure  that
applies to the other 50% of the award based upon the relative ranking of the Company’s total stockholder return for the three year performance period compared to
the total stockholder returns of an established comparison group of companies over the same period (the “2019 Market Condition”). The 2019 Performance-Based
RSUs  are  also  subject  to  a  three  year  service  vesting  provision  (the  “service  vesting  condition”)  and  are  scheduled  to  cliff  vest  on  the  date  the  final  vesting
percentage is determined following the end of the three year performance period under the awards. The 2019 FFO Performance Condition was achieved at 175% of
target for one participant and 150% of target for all other participants. The number of 2019 Performance-Based RSUs ultimately earned could fluctuate from the
target number of 2019 Performance-Based RSUs granted based upon the levels of achievement for the 2019 Debt to EBITDA Ratio Performance Condition, the
2019 Market Condition, and the extent to which the service vesting condition is satisfied. The estimate of the number of 2019 Performance-Based RSUs earned is
evaluated  quarterly  during  the  performance  period  based  on  our  estimate  for  each  of  the  performance  conditions  measured  against  the  applicable  goals.
Compensation  expense  for  the  2019  Performance-Based  RSU  grant  is  recognized  on  a  straight-line  basis  over  the  requisite  service  period  for  each  participant,
which is generally the three year service period.

The 2018 Performance-Based RSUs are scheduled to vest at the end of a three year period (consisting of calendar years 2018-2020). A target number of 2018
Performance-Based RSUs were awarded, and the final number of 2018 Performance-Based RSUs that vest (which may be more or less than the target number) will
be based upon (1) the achievement of pre-set FFO per share goals for the year ending December 31, 2018 that applies to 100% of the Performance-Based RSUs
awarded  (the  “2018  FFO  Performance  Condition”)  and  (2)  a  performance  measure  that  applies  to  50%  of  the  award  based  upon  a  measure  of  the  Company’s
average debt to EBITDA ratio for the three year performance period (the “2018 Debt to EBITDA Ratio Performance Condition” and together with the 2018 FFO
Performance Condition, the “2018 Performance Conditions”) and a market measure that applies to the other 50% of the award based upon the relative ranking of
the Company’s TSR for the three year performance period compared to the TSR of an established comparison group of companies over the same period (the “2018
Market  Condition”).  Based  on  the  combined  results  of  the  2018  Performance  Conditions  and  the  2018  Market  Condition,  the  2018  Performance-Based  RSUs
achieved a weighted average of 219% for one participant and 175% for the others of their target level of performance.

As of December 31, 2020, the estimated number of RSUs earned for the 2020 and 2019 Performance-Based RSUs and the actual number of RSUs earned for

Performance Conditions and the 2018 Market Condition.

Each Performance-Based RSU represents the right to receive one share of our common stock in the future, subject to, and as modified by, the Company’s level
of achievement of the applicable performance and market conditions. The fair values of the 2020 Performance-Based RSUs, 2019 Performance-Based RSUs and
2018 Performance-Based RSUs were $12.9 million at January 31, 2020, $10.2 million at February 1, 2019, and $10.8 million at February 14, 2018, respectively.
The fair values for the awards with market conditions were calculated using a Monte Carlo simulation pricing model based on the assumptions in the table below.
The determination of the fair value of the 2020, 2019 and 2018 Performance-Based RSUs takes into consideration the likelihood of achievement of the 2020, 2019
and  2018  Performance  Conditions  and  the  2020,  2019  and  2018  Market  Conditions,  respectively,  as  discussed  above.  The  following  table  summarizes  the

The computation of expected volatility was based on a blend of the historical volatility of our shares of common stock over a period of twice the remaining
performance period as of the grant date and implied volatility data based on the observed pricing of six month publicly-traded options on shares of our common
stock. The risk-free interest rate was based on the yield curve on zero-coupon U.S. Treasury STRIP securities in effect at January 31, 2020, February 1, 2019, and
February 14, 2018.

Compensation expense for the Performance-Based RSUs is recognized on a straight-line basis over the requisite service period for each participant, which is
generally the three-year service period. As of December 31, 2020, the number of 2020 Performance-Based RSUs estimated to be earned based on the Company’s
estimate of the performance conditions measured against the applicable goals was 142,004, and the compensation cost recorded to date for this program was based
on that estimate. For the portion of the 2020 Performance-Based RSUs subject to the 2020 Market Condition, for the year ended December 31, 2020, we recorded
compensation  expense  based  upon  the  $84.54  fair  value  per  share  at  January  31,  2020.  Compensation  expense  will  be  variable  for  the  portion  of  the  2020
Performance-Based RSUs subject to the 2020 Debt to EBITDA Ratio Performance Condition, based upon the outcome of that condition. As of December 31, 2020,
the  number  of  2019  Performance-Based  RSUs  estimated  to  be  earned  based  on  the  Company’s  estimate  of  the  performance  conditions  measured  against  the
applicable goals was 220,151, and the compensation cost recorded to date for this program was based on that estimate. For the portion of the 2019 Performance-
Based RSUs subject to the 2019 Market Condition, for the years ended December 31, 2020 and 2019, we recorded compensation expense based upon the $72.57
fair value per share at February 1, 2019. Compensation expense will be variable for the portion of the 2019 Performance-Based RSUs subject to the 2019 Debt to
EBITDA Performance Condition, based upon the outcome of that condition. For the years ended December 31, 2020, 2019 and 2018, we recorded compensation
expense for the portion of the 2018 Performance-Based RSUs subject to the 2018 Market Condition based upon the $70.08 fair value per share at February 14,
2018 and for the portion of the 2018 Performance-Based RSUs subject to the 2018 Debt to EBITDA Ratio Performance Condition, based on the stock price at date

Share-Based Compensation Cost Recorded During the Period

Share-based  compensation  costs  for  the  year  ended  December  31,  2020  include  $4.5  million  of  accelerated  share-based  compensation  costs  related  to
severance packages, including for the departure of an executive officer. The total compensation cost for all share-based compensation programs was $37.6 million,
$32.8 million and $35.9 million for the years ended December 31, 2020, 2019 and 2018, respectively. Of the total share-based compensation costs, $7.4 million,
$5.8 million and $8.0 million was capitalized as part of real estate assets and for 2018, deferred leasing costs, for the years ended December 31, 2020, 2019 and
2018,  respectively.  As  of  December  31,  2020,  there  was  approximately  $35.1  million  of  total  unrecognized  compensation  cost  related  to  nonvested  incentive
awards  granted  under  share-based  compensation  arrangements  that  is  expected  to  be  recognized  over  a  weighted-average  period  of  1.4  years.  The  remaining
compensation cost related to these nonvested incentive awards had been recognized in periods prior to December 31, 2020. The $35.1 million  of unrecognized
compensation costs does not reflect the future compensation cost related to share-based awards that were granted subsequent to December 31, 2020.

Severance Compensation

For  the  year  ended  December  31,  2020,  compensation  costs  included  in  general  and  administrative  expenses  on  our  consolidated  statements  of  operations
include $14.1 million of cash severance costs related to the departure of an executive officer, in addition to the accelerated share-based compensation costs noted in
the paragraph above.

Other Compensation

On December 27, 2018, the Executive Compensation Committee of the Company’s Board approved, and the Company and the Operating Partnership entered
into the Amended Employment Agreement with John Kilroy, which amends and supersedes the existing employment agreement dated January 1, 2012. Except as
noted  below,  the  Amended  Employment  Agreement  continues  Mr.  Kilroy’s  employment  on  terms  substantially  similar  to  those  of  the  existing  employment
agreement, with a new term scheduled to continue through December 31, 2023. The Amended Employment Agreement includes a cash retirement benefit of $13.2
million, or $16.2 million for a retirement at or after attaining age 73, with at least twelve months’ advance notice or at or after the end of the term of the agreement.
For  the  year  ended  December  31,  2018,  the  Company  recognized  $12.1  million  of  compensation  expense  in  general  and  administrative  expenses  on  the
consolidated statement of operations, representing the present value of the potential cash retirement benefit amount that was earned based on prior service. For the
years  ended  December  31,  2020  and  2019,  the  Company  recognized  $1.5  million  of  compensation  expense  in  general  and  administrative  expenses  on  the
consolidated statement of operations related to the Amended Employment Agreement.

16.    Employee Benefit Plans

401(k) Plan

We have a retirement savings plan designed to qualify under Section 401(k) of the Code (the “401(k) Plan”). Our employees are eligible to participate in the
401(k) Plan on the first day of the month after three months of service. The 401(k) Plan allows eligible employees (“401(k) Participants”) to defer up to 60% of
their eligible compensation on a pre-tax basis, subject to certain maximum amounts allowed by the Code. The 401(k) Plan provides for a matching contribution by
the Company in an amount equal to 50 cents of each one dollar of participant contributions up to a maximum of 10% of the 401(k) Participant’s annual salary.
401(k)  Participants  vest  immediately  in  the  amounts  contributed  by  us.  For  each  of  the  years  ended  December  31,  2020,  2019,  and  2018,  we  contributed  $1.6
million, $1.6 million and $1.5 million, respectively, to the 401(k) Plan.

Deferred Compensation Plan

In 2007, we adopted the Deferred  Compensation  Plan, under which directors  and certain  management  employees  may defer receipt  of their compensation,
including up to 70% of their salaries and up to 100% of their director fees and bonuses, as applicable. In addition, employee participants will receive mandatory
Company contributions to their Deferred  Compensation Plan accounts equal to 10% of their gross monthly salaries,  without regard to whether such employees
elect  to defer  salary  or bonus compensation  under the  Deferred  Compensation  Plan. Our Board may, but has no obligation  to, approve additional  discretionary
contributions by the Company to Participant accounts. We hold the Deferred Compensation Plan assets in a limited rabbi trust, which is subject to the claims of our
creditors in the event of bankruptcy or insolvency.

See Note 19 “Fair Value Measurements and Disclosures” for further discussion of our Deferred Compensation Plan assets as of December 31, 2020 and 2019.

Our liability of $27.4 million and $27.0 million under the Deferred Compensation Plan was fully funded as of December 31, 2020 and 2019, respectively.

17.    Rental Income and Future Minimum Rent

Our rental income is primarily comprised of payments defined under leases and are either subject to scheduled fixed increases or adjustments in rent based on
the Consumer Price Index. Additionally, rental income includes variable payments for tenant reimbursements of property-related expenses and payments based on
a percentage of tenant’s sales.

The  table  below  sets  forth  the  allocation  of  rental  income  between  fixed  and  variable  payments  and  net  collectability  reversals  or  recoveries  for  the  years

ended December 31, 2020 and 2019:

$18.4 million of write-offs related to the cumulative impact of transitioning certain tenants to a cash basis of reporting primarily as a result of the COVID-19 pandemic. Also includes a
$0.6  million  net  increase  to  the  allowance  for  doubtful  accounts,  which  includes  the  impact  of  $2.2  million  of  reversals  to  the  allowance  for  doubtful  account  for  tenants  that  had  an
allowance at January 1, 2020 and were subsequently transitioned to a cash basis of reporting during 2020. These reversals are included in the $18.4 million of write-offs above.

We have operating leases with tenants that expire at various dates through 2044 and are either subject to scheduled fixed increases or adjustments in rent based
on the Consumer Price Index. Generally, the leases grant tenants renewal options. Leases also provide for additional rents based on certain operating expenses.

are not assumed to be exercised in our calculation of the present value of the future minimum lease payments for this lease.

(3)    We entered into this ground lease in connection with an operating property acquisition in 2019. Refer to Note 3 “Acquisitions” for additional information.

To determine the discount rates used to calculate the present value of the minimum future lease payments for our ground leases, we used a hypothetical curve
derived from unsecured corporate borrowing rates over the lease term. The weighted average discount rate used to determine the present value of our minimum
lease payments was 5.11%. As of December 31, 2020, the weighted average remaining lease term of our ground leases is 54 years. For the years ended December
31, 2020 and 2019, variable lease costs totaling $3.0 million and $2.9 million, respectively, were recorded to ground leases expense on our consolidated statements
of operations.

obligation in effect as of December 31, 2020.

(3)    One of our ground lease obligations  includes  a component  which is based on the percentage of gross income  that  exceeds the minimum  ground rent. The minimum  rent is subject  to
increases every five years based on 50% of the average annual percentage rent for the previous five years. The contractual obligations for that lease included above assume the current
annual ground lease obligation in effect at December 31, 2020 for the remainder of the lease term since we cannot predict future adjustments.

(4)    One of our ground lease obligations is subject to a fair market value adjustment every five years based on a combination of CPI adjustments and third-party appraisals limited to maximum
increases annually. The contractual obligations for that lease included above assume the current annual ground lease obligation in effect at December 31, 2020 for the remainder of the
lease term since we cannot predict future adjustments.

(5)    One of our ground lease obligations includes a component which is based on the percentage of adjusted gross income that exceeds the minimum ground rent. The minimum rent is subject
to increases every 10 years by an amount equal to 60% of the average annual percentage rent for the previous three years. The contractual obligations for this lease included above assume
the current annual ground lease obligation in effect at December 31, 2020 for the remainder of the lease term since we cannot predict future adjustments.
(6)    One of our ground lease obligations is subject to fixed 5% ground rent increases every five years, with the next increase occurring on December 1, 2022.

Environmental Matters

We follow the policy of monitoring all of our properties, including acquisition, development, and existing stabilized portfolio properties, for the presence of
hazardous  or  toxic  substances.  While  there  can  be  no  assurance  that  a  material  environmental  liability  does  not  exist,  we  are  not  currently  aware  of  any
environmental liability with respect to our stabilized portfolio properties that would have a material adverse effect on our financial condition, results of operations
and cash flow, or that we believe would require additional disclosure or the recording of a loss contingency.

As of December  31, 2020  and  2019, we  had accrued  environmental  remediation  liabilities  of approximately  $71.3 million  and  $80.7 million,  respectively,
recorded on our consolidated balance sheets in connection with certain of our in-process and future development projects. The accrued environmental remediation
liabilities  represent  the  remaining  costs  we estimate  we  will  incur  prior  to  and  during  the  development  process  at  various  development  acquisition  sites.  These
estimates, which we developed with the assistance of third party experts, consist primarily of the removal of contaminated soil, performing environmental closure
activities, constructing remedial systems, and other related costs since we are required to dispose of any existing contaminated soil, and sometimes perform other
environmental closure or remedial activities, when we develop new buildings at these sites.

We record estimated environmental remediation obligations for acquired properties at the acquisition date when we are aware of such costs and when such
costs are probable of being incurred and can be reasonably estimated. Estimated costs related to development environmental remediation liabilities are recorded as
an increase to the cost of the development project. Actual costs are recorded as a decrease to the liability when incurred. These accruals are adjusted as an increase
or decrease to the development project costs and as an increase or decrease to the accrued environmental remediation liability if we obtain further information or
circumstances change. The environmental remediation obligations recorded at December 31, 2020 and 2019 were not discounted to their present values since the
amount and timing of cash payments are not fixed. It is possible that we could incur additional environmental

F - 55

 
KILROY REALTY CORPORATION AND KILROY REALTY, L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

remediation  costs  in  connection  with  these  development  projects.    However,  potential  additional  environmental  costs  for  these  development  projects  cannot  be
reasonably estimated at this time and certain changes in estimates could occur as the site conditions, final project timing, design elements, actual soil conditions
and other aspects of the projects, which may depend upon municipal and other approvals beyond the control of the Company, are determined.

Other than the accrued environmental liabilities discussed above, we are not aware of any unasserted claims and assessments with respect to an environmental

liability that we believe would require additional disclosure or the recording of an additional loss contingency.

Litigation

We and our properties are subject to litigation arising in the ordinary course of business. To our knowledge, neither we nor any of our properties are presently
subject to any litigation or threat of litigation which, if determined unfavorably to us, would have a material adverse effect on our cash flow, financial condition, or
results of operations.

Insurance

We  maintain  commercial  general  liability,  auto  liability,  employers’  liability,  umbrella/excess  liability,  special  form  property,  difference  in  conditions
including earthquake and flood, environmental, rental loss, and terrorism insurance covering all of our properties. Management believes the policy specifications
and insured limits are reasonable given the relative risk of loss, the cost of the coverage, and industry practice. We do not carry insurance for generally uninsurable
losses such as loss from governmental action, nuclear hazard, and war and military action. Policies are subject to various terms, conditions, and exclusions and
some policies may involve large deductibles or co-payments.

funds selected by each participant, which results in a corresponding increase or decrease to compensation cost included in general and administrative expenses on
our consolidated statements of operations for the period.

____________________
(1) On January 1, 2019, the Company adopted Topic 842 on a modified retrospective basis and recognized a cumulative-effect adjustment to distributions in excess of earnings related to the
allowances  for  uncollectible  tenant  receivables  and  deferred  rent  receivables.  As  such,  the  ending  balances  of  the  allowances  for  uncollectible  tenant  receivables  and  deferred  rent
receivables at December 31, 2018 do not equal the beginning balances on January 1, 2019.

(2) For the years ended December 31, 2020 and 2019, amounts do not reflect leases deemed not probable of collection for which we reversed the associated revenue under Topic 842. In
addition, for the years ended December 31, 2020, 2019 and 2018, $1.7 million, $0.7 million and $2.9 million, respectively, was charged to costs and expenses for a valuation allowance for
a note receivable.

(3) For the year ended December 31, 2020, includes reversals of allowance for doubtful accounts for tenants with an allowance at January 1, 2020 that were subsequently transitioned to a cash

basis of reporting.

DESCRIPTION OF CAPITAL STOCK

The following is a description of some of the material terms and provisions of the capital stock of Kilroy Realty Corporation registered under Section 12
of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The following description is a summary only and does not purport to be complete and
is subject to, and qualified in its entirety by reference to the provisions of the Company’s charter and bylaws, copies of which have been filed as exhibits to the
Annual Report on Form 10-K to which this “Description of Capital Stock” is an exhibit, and the applicable provisions of the Maryland General Corporation Law
(the “MGCL”). While we believe the following description covers the material terms and provisions of our common stock it may not include all of the information
that is important to you. We encourage you to read carefully the applicable provisions of the MGCL and our charter and bylaws for a more complete understanding
of our common stock. As used in this “Description of Capital Stock,” references to the “Company,” “we,” “our” or “us” refer solely to Kilroy Realty Corporation
and not to any of its subsidiaries, unless otherwise expressly stated or the context otherwise requires.

Common Stock

General

The Company’s charter authorizes us to issue up to 280,000,000 shares of common stock, par value $.01 per share. As of December 31, 2020, we had

116,035,827 shares of common stock issued and outstanding.

Shares of our common stock:

•

•

•

•

•

•

•

•

are entitled to one vote per share on all matters presented to stockholders generally for a vote, including the election of directors, with no right to
cumulative voting;

do not have any conversion rights;

do not have any exchange rights;

do not have any sinking fund rights;

do not have any redemption rights;

do not generally have any appraisal rights;

do not have any preemptive rights to subscribe for any of our securities; and

are subject to restrictions on ownership and transfer.

We may pay dividends and other distributions on shares of the Company’s common stock, subject to the preferential rights of any series or class of capital

stock that we may issue in the future with rights to dividends and other distributions senior to the Company’s common stock or creditors, in the case of our
liquidation, dissolution or winding-up. However, we may only pay dividends when the board of directors (in its sole discretion) authorizes and declares a dividend
out of legally available funds therefor. All dividends and other distributions will be paid to the holders of our common stock on pro rata basis.

The Company’s board of directors may:

in its sole discretion, classify or reclassify any unissued shares of the Company’s common stock into other classes or series of capital stock, whether now
or hereafter authorized;

establish the number of shares in each of these classes or series of capital stock;

establish the par value of the shares in each of these classes or series of capital stock;

establish any preference rights, conversion rights and other rights, including voting powers, of each of these classes or series of capital stock;

establish restrictions, such as limitations and restrictions on ownership, transfer, dividends or other distributions of each of these classes or series of
capital stock; and

establish qualifications and terms or conditions of redemption for each of these classes or series of capital stock.

•

•

•

•

•

•

In addition, the Company does not have a classified board of directors.

Preferred Stock

The Company’s charter authorizes us to issue up to 30,000,000 shares of preferred stock, par value $.01 per share, none of which are currently classified and

designated or are issued and outstanding. As of December 31, 2020, 30,000,000 shares of the Company’s preferred stock were available for classification,
designation and issuance.

We may classify, designate and issue authorized shares of preferred stock, in one or more classes or series, as authorized by the board of directors without

the prior consent of the Company’s stockholders. The board of directors may grant the holders of preferred stock of any class or series preferences, powers and
rights—voting or otherwise—senior to the rights of holders of shares of the Company’s common stock. The board of directors can authorize the issuance of
currently authorized shares of preferred stock with terms and conditions that could have the effect of delaying or preventing a change of control transaction that
might involve a premium price for holders of shares of the Company’s common stock or otherwise be in their best interest. All shares of preferred stock that and
are or become issued and outstanding are or will be fully paid and nonassessable. Before we may issue any shares of preferred stock of any class or series, the
MGCL and the Company’s charter require the board of directors to determine the following with respect to such class or series:

•

•

•

•

•

•

•

•

•

the designation;

the terms;

preferences with respect to distributions and in the event of our liquidation, dissolution or winding-up;

conversion and other rights, if any;

voting powers;

restrictions;

limitations as to distributions;

qualifications; and

terms or conditions of redemption, if any.

Restrictions on Ownership and Transfer of the Company’s Capital Stock

Internal Revenue Code Requirements

To maintain the Company’s tax status as a REIT, five or fewer “individuals,” as that term is defined in the Code, which includes certain entities, may not
own, actually or constructively, more than 50% in value of the Company’s issued and outstanding capital stock at any time during the last half of a taxable year.
Constructive ownership provisions in the Code determine if any individual or entity constructively owns the Company’s capital stock for purposes of this
requirement. In addition, 100 or more persons must beneficially own the Company’s capital stock during at least 335 days of a taxable year or during a
proportionate part of a short taxable year. Also, rent from tenants in which we actually or constructively own a 10% or greater interest is not qualifying income for
purposes of the gross income tests of the Code. To help ensure we meet these tests, the Company’s charter restricts the acquisition and ownership of shares of the
Company’s common stock.

Transfer Restrictions in the Company’s Charter

Subject to exceptions specified therein, the Company’s charter provides that no holder may own, either actually or constructively under the applicable
constructive ownership provisions of the Code, more than 7.0%, by number of shares or value, whichever is more restrictive, of the outstanding shares of the
Company’s common stock.

In addition, because rent from tenants in which we actually or constructively own a 10% or greater interest is not qualifying rent for purposes of the gross
income tests under the Code, the Company’s charter provides that no holder may own, either actually or constructively by virtue of the constructive ownership
provisions of the Code, which differ from the constructive ownership provisions used for purposes of the preceding sentence, more than 9.8%, by number of shares
or value, whichever is more restrictive, of the outstanding shares of the Company’s common stock.

We refer to the limits described in the two preceding paragraphs, together, as the “ownership limits.”

The constructive ownership provisions set forth in the Code are complex, and may cause shares of the Company’s common stock owned actually or
constructively by a group of related individuals and/or entities to be constructively owned by one individual or entity. As a result, the acquisition of shares of the
Company’s common stock in an amount that does not exceed the ownership limits, or the acquisition of an interest in an entity that actually or constructively owns
the Company’s common stock, could, nevertheless cause that individual or entity, or another individual or entity, to own constructively shares in excess of the
ownership limits and thus violate the ownership limits described above or otherwise permitted by the Company’s board of directors.

The Company’s charter permits the board of directors to waive the ownership limits with respect to a particular common stockholder if the board of

directors, among other things:

•

•

determines that such waiver will not cause any individual’s beneficial ownership of shares of the Company’s common stock to violate the 7.0% limitation
described above or that any exemption from such ownership limit will not cause the Company to fail to qualify as a REIT; and

determines that such stockholder does not and will not own, actually or constructively, an interest in a tenant of the Company (or a tenant of any entity
owned in whole or in part by the Company) that would cause the Company to own, actually or constructively, more than a 9.8% interest (as set forth in
Section 856(d)(2)(B) of the Code) in such tenant, subject to certain exceptions.

As a condition of this waiver, the Company’s board of directors may require opinions of counsel satisfactory to it and/or undertakings or representations
from the applicant with respect to preserving the Company’s REIT status. The board of directors has waived the ownership limit applicable to the Company’s
common stock for John B. Kilroy, Sr. and John Kilroy, members of their families and some of their affiliated entities, allowing them to own up to 19.6% of the
Company’s common stock. However, the board of directors conditioned this waiver upon the receipt of undertakings and representations from Messrs. Kilroy
which it believed were reasonably necessary to conclude that the waiver would not cause us to fail to qualify and maintain the Company’s status as a REIT.

In addition to the foregoing ownership limits, the Company’s charter provides that no holder may own, either actually or constructively under the applicable

attribution rules of the Code, any shares of the Company’s common stock if, as a result of this ownership:

• more than 50% in value of the Company’s outstanding common stock would be owned, either actually or constructively under the applicable constructive

ownership provisions of the Code, by five or fewer individuals, as defined in the Code; or

•

the Company would fail to qualify as a REIT.

If shares of common stock are transferred to any person in a manner which result in the Company’s capital stock being beneficially owned by less than 100

persons (determined without reference to any rules of attribution), the Company’s charter provides that the transfer shall be null and void in its entirety, and the
intended transferee will acquire no rights in such common stock.

Under the Company’s charter, any person who acquires or attempts or intends to acquire actual or constructive ownership of the Company’s shares of
common stock that violate any of the foregoing restrictions on transferability and ownership must give us notice immediately and provide us with any other
information that we may request to determine the effect of the transfer on the Company’s status as a REIT. The foregoing restrictions on transferability and
ownership will not apply if the Company’s board of directors determines that it is no longer in the Company’s best interest to attempt to qualify, or to continue to
qualify, as a REIT and such determination is approved by the affirmative vote of holders of at least two-thirds of the shares of the Company’s capital stock
outstanding and entitled to vote thereon.

The terms of any class or series of preferred stock that we may issue in the future may include restrictions on ownership and transfer, and provide for
exceptions to or waivers of those restrictions, similar to those described under this caption “—Transfer Restrictions in the Company’s Charter,” as well as remedies
for violation of those restrictions similar to those described below under “—Effect of Violation of Ownership Limits and Transfer Restrictions.”

Effect of Violation of Ownership Limits and Transfer Restrictions

The Company’s charter provides that if any transfer or other event occurs that, if effective, would result in any person owning shares of Company’s common

stock in violation of the ownership limits or other restrictions on ownership and transfer of our stock described above, the number of shares of common stock that
otherwise would cause such person to violate the ownership limits or other restrictions on ownership and transfer of our stock (the

“excess shares”) will be transferred automatically to a trust, the beneficiary of which will be a qualified charitable organization selected by us or, if for any reason
that transfer is not automatically effective, then the transfer of such excess shares shall be void ab initio and the purported transferee will not have any rights in
such excess shares. The automatic transfer will be effective as of the close of business on the business day prior to the date of the violative transfer.

The trustee of the charitable trust must:

•

within 20 days of receiving notice from us of the transfer of excess shares to the trust,

◦

◦

sell the excess shares to a person or entity who could own the shares without violating the ownership limits or as otherwise permitted by the
board of directors, and

distribute to the prohibited transferee or owner, as applicable, an amount equal to the lesser of the price paid by the prohibited transferee or
owner for the excess shares (or, if the event which resulted in the transfer to the charitable trust did not involve a purchase of the applicable stock
for fair value, the market price of such shares on the day of the event which resulted in such transfer to the charitable trust) or the sales proceeds
(net any commissions and other expenses of sale) received by the trust for the excess shares; and   

•

distribute any proceeds in excess of the amount distributable to the prohibited transferee or owner, as applicable, to the charitable organization selected by
us as beneficiary of the trust.

Excess shares transferred to the charitable trust shall be deemed to have been offered for sale to us at a price per share equal to the lesser of the price paid by

the prohibited transferee or owner for the excess shares (or, if the event which resulted in the transfer to the charitable shares did not involve the purchase of the
applicable stock for fair value, the market price of such shares on the day of the event which resulted in the transfer of such shares to the charitable trust) and the
market price on the date we accept such offer. We will have the right to accept such offer until the charitable trust has sold the excess shares as described above.

The trustee shall be designated by us and be unaffiliated with us and any prohibited transferee or owner. Prior to a sale of any excess shares by the trust, the
trustee will receive, in trust for the beneficiary, all dividends and other distributions paid by us with respect to the excess shares, and may also exercise all voting
rights with respect to the excess shares.

The Company’s charter provides that, subject to Maryland law, effective as of the date that the shares have been transferred to the trust, the trustee shall have

the authority, at the trustee’s sole discretion:

•

•

to rescind as void any vote cast by a prohibited transferee or owner, as applicable, prior to our discovery that the Company’s shares have been transferred
to the trust; and

to recast the vote in accordance with the desires of the trustee acting for the benefit of the beneficiary of the trust.

However, if we have already taken irreversible corporate action, then the trustee may not rescind and recast the vote. Any dividend or other distribution paid

to the prohibited transferee or owner, prior to our discovery that the shares had been automatically transferred to a trust as described above, must be repaid to the
trustee upon demand for distribution to the beneficiary of the trust. If the transfer to the trust as described above is not automatically effective, for any reason, to
prevent violation of the applicable ownership limit or as otherwise permitted by the board of directors, then the Company’s charter provides that the transfer of the
excess shares will be void ab initio.

If the Company’s board of directors shall at any time determine in good faith that a person has acquired, intends to acquire or own, has attempted to acquire
or own, or may acquire or own the Company’s common stock in violation of the limits described above, the Company’s charter provides that the board of directors
shall take actions to refuse to give effect to or to prevent the ownership or acquisition, including, but not limited to:

•

•

•

authorizing us to repurchase stock;

refusing to give effect to the ownership or acquisition on our books; or

instituting proceedings to enjoin the ownership or acquisition.

All certificates representing shares of the Company’s capital stock bear a legend referring to the restrictions described above.

All persons who own at least a specified percentage of the issued and outstanding shares of the Company’s stock must file with us a completed questionnaire

annually containing information about their ownership of the shares, as set forth in the applicable Treasury regulations. Under current Treasury regulations, the
percentage is between 0.5% and 5.0%, depending on the number of record holders of the Company’s shares. In addition, each stockholder may be required to
disclose to us in writing information about the actual and constructive ownership of the Company’s shares as the board of directors deems necessary to comply
with the provisions of the Code applicable to a REIT or to comply with the requirements of any taxing authority or governmental agency.

These ownership limitations could discourage a takeover or other transaction in which holders of some, or a majority, of the Company’s shares of capital
stock might receive a premium for their shares over the then prevailing market price or which stockholders might believe to be otherwise in their best interest.

Certain Provisions of the Maryland General Corporation Law and of the Company’s Charter and Bylaws

Under the Maryland General Corporation Law, or the MGCL, the Company’s stockholders are generally not liable for our debts or obligations. In the event
of the voluntary or involuntary liquidation, dissolution or winding-up of the Company, we will first pay all debts and other liabilities, including debts and liabilities
arising out of the Company’s status as general partner of the operating partnership, and, second, any preferential distributions on any issued and outstanding shares
of our preferred stock, if any. Each holder of the Company’s common stock then will share ratably in our remaining assets. All shares of the Company’s common
stock  have  equal  distribution,  liquidation  and  voting  rights,  and  have  no  preference  or  exchange  rights,  subject  to  the  transfer  and  ownership  limits  in  the
Company’s charter or as permitted by the board of directors pursuant to executed agreements waiving these ownership limits with respect to specific stockholders.

Under the MGCL, we generally require approval by the Company’s stockholders by the affirmative vote of at least two-thirds of the votes entitled to vote

before we can:
 authorizing us to repurchase stock;

•

•

dissolve;

amend the Company’s charter (except for limited exceptions);

• merge;

•

•

•

sell all or substantially all of the Company’s assets;

engage in a share exchange; or

engage in similar transactions outside the ordinary course of business.

Under the MGCL and our charter, the board of directors may, without stockholder approval, make certain minor amendments to the charter, and if the
charter allows, which ours does, classify or reclassify any unissued stock from time to time by setting or changing the preferences, conversion or other rights,
voting powers, restrictions, limitations as to dividends, qualifications, or terms or conditions of redemption of the stock.

With respect to the sale of all or substantially all of the Company’s assets, because the term “substantially all” of a company’s assets is not defined in the

MGCL, it is subject to Maryland common law and to judicial interpretation and review in the context of the unique facts and circumstances of any particular
transaction.

Although the MGCL allows the Company’s charter to establish a lesser percentage of affirmative votes by the Company’s stockholders for approval of those

actions, the Company’s charter does not include such a provision.

The Board of Directors

The Company’s charter provides that the number of the directors shall be six directors until that number is increased or decreased in accordance with the
bylaws of the Company; provided, however, such number cannot be less than the minimum number required by the MGCL, which is one. The Company’s bylaws
allow the board of directors to fix or change the number to not fewer than three and not more than 13 members. The number of directors is currently fixed at six. A
majority of the remaining board of directors may fill any vacancy, other than a vacancy caused by removal. A majority of the board of directors may fill a vacancy
resulting from an increase in the number of directors. The stockholders entitled to vote for the election of directors at an annual or special meeting of the
Company’s stockholders may fill a vacancy resulting from the removal of a director.

The Company’s charter and bylaws provide that a majority of the board of directors must be “independent directors.” An “independent director” is a

director who is not:

•

•

•

an employee, officer or affiliate of us or one of our subsidiaries or divisions;

a relative of a principal executive officer; or

an individual member of an organization acting as advisor, consultant or legal counsel, who receives compensation on a continuing basis from us in
addition to director’s fees.

No Cumulative Voting

Holders of shares of Company common stock have no right to cumulative voting for the election of directors. Consequently, at each annual meeting of the

Company’s stockholders, the holders of a majority of the shares of Company common stock entitled to vote will be able to elect all of the successors of the
directors at that meeting.

Removal of Directors

The Company’s charter provides that its stockholders may remove a director only for “cause” and only by the affirmative vote of at least two-thirds of the

shares entitled to vote in the election of directors. The MGCL does not define the term “cause.” As a result, removal for “cause” is subject to Maryland common
law and to judicial interpretation and review in the context of the unique facts and circumstances of any particular situation.

Election of Directors

The Company’s bylaws provide a majority vote standard for uncontested elections of directors. As a result, except in the case of directors to be elected by

the holders of any class or series of the Company’s preferred stock, at each meeting of stockholders at which the election of directors is uncontested, a director
nominee will be elected to the board of directors only if the number of votes cast “FOR” the nominee exceeds the number of votes cast “AGAINST” the nominee
(with abstentions and broker non-votes not counted as a vote cast either “FOR” or “AGAINST” the director nominee). A plurality vote standard applies in
contested elections, in which case stockholders will not be permitted to vote “AGAINST” any director nominee but will only be permitted to vote “FOR” or
withhold their vote with respect to such nominee. An election will be considered to be contested if the Company’s secretary has received notice that a stockholder
or group of stockholders has nominated or proposes to nominate one or more persons for election as a director, such notice purports to be in compliance with the
advance notice requirements or the proxy access requirements set forth in the Company’s bylaws, and, at least 14 days prior to the date on which notice of the
meeting is first mailed to stockholders, the nomination has not been withdrawn and would thereby cause the number of director nominees to exceed the number of
directors to be elected at the meeting.

Under the MGCL, if an incumbent director is not re-elected at a meeting of stockholders at which he or she stands for re-election in an uncontested

election, then the incumbent director continues to serve in office as a holdover director until his or her successor is elected and qualifies. However, the Company’s
bylaws provide that if an incumbent director is not re-elected due to his or her failure to receive a majority of the votes cast in an uncontested election, the director
will promptly tender his or her resignation as a director, subject to acceptance by the board of directors, for consideration by the nominating and corporate
governance committee of the board of directors. The nominating and corporate governance committee of the board of directors will then make a recommendation
to the board of directors as to whether to accept or reject the tendered resignation or whether other action should be taken. The board of directors will publicly
disclose within 90 days of certification of the stockholder vote its decision and rationale regarding whether to accept, reject or take other action with respect to the
tendered resignation. If a director’s tendered resignation is not accepted by the board of directors, such director would continue to serve until the next annual
meeting of stockholders and until his or her successor is elected and qualified or his or her earlier death, retirement, resignation or removal. If a director’s tendered
resignation is accepted, then the board of directors may, among other things, fill the resulting vacancy or decrease the size of the board of directors.

The Company is not Subject to the Maryland Business Combination Act

The Company has elected not to be subject to the “business combination” provisions of the MGCL (Sections 3-601 through 3-605) pursuant to the board

of directors’ adoption of certain resolutions related thereto. Such resolutions also provide that the board of directors cannot rescind such election and become
subject to these business combination provisions without the approval of holders of a majority of its shares entitled to vote.

In the event that the Company decides to be subject to the business combinations provision, “business combinations” between a Maryland corporation and

an interested stockholder or an affiliate of an interested stockholder are generally prohibited for five years after the most recent date on which the interested
stockholder becomes an interested stockholder. A business combination includes a merger, consolidation or share exchange. A business combination may also
include an asset transfer or issuance or reclassification of equity securities. An interested stockholder is defined in the MGCL as:

•

•

any person (other than the corporation or any subsidiary) who beneficially owns, directly or indirectly, ten percent or more of the voting power of the
corporation’s shares; or

an affiliate or associate of the corporation who, at any time within the two-year period prior to the date in question, was the beneficial owner, directly or
indirectly, of ten percent or more of the voting power of the then outstanding stock of the corporation.

A person is not an interested stockholder under the business combinations provisions of the MGCL if the board of directors approved in advance the

transaction by which such person would otherwise have become an interested stockholder.

At the conclusion of the five-year prohibition, any business combination between the Maryland corporation and an interested stockholder generally must

be recommended by the board of directors of the corporation and approved by the affirmative vote of at least:

•

•

80% of the votes entitled to be cast by holders of outstanding shares of voting stock of the corporation; and

two-thirds of the votes entitled to be cast by holders of voting stock of the corporation other than shares held by the interested stockholder with whom or
with whose affiliate the business combination is to be effected or held by an affiliate or associate of the interested stockholder.

These super-majority vote requirements do not apply if the corporation’s common stockholders receive a minimum price, as defined under the MGCL, for

their shares in the form of cash or other consideration in the same form as previously paid by the interested stockholder for its shares. None of these provisions of
the MGCL will apply, however, to business combinations that are approved or exempted by the board of directors of the corporation prior to the time that the
interested stockholder becomes an interested stockholder.

As a result of the Company’s decision not to be subject to the business combinations statute, an interested stockholder would be able to effect a “business

combination” without complying with the requirements discussed above, which may make it easier for stockholders who become interested stockholders to
consummate a business combination involving the Company. However, the Company cannot assure you that any business combinations will be consummated or, if
consummated, will result in a purchase of shares of capital stock from its stockholders at a premium.

The Company is not Subject to the Maryland Control Share Acquisition Act

The Company has elected in its bylaws not to be subject to the “control share acquisition” provisions of the MGCL (Sections 3-701 through 3-710). If it

wants to be subject to these provisions, its bylaws would need to be amended. Such amendments would require the approval of the holders of a majority of all
votes entitled to be cast by the holders of the issued and outstanding shares of the Company’s common stock.

The MGCL provides that “control shares” of a company acquired in a “control share acquisition” have no voting rights except to the extent approved by a

vote of two-thirds of the votes entitled to vote, excluding shares owned by the acquiror or by officers or directors who are employees of the Company. “Control
shares” are voting shares of stock which, if aggregated with all other voting shares of stock previously acquired by the acquiror, or over which the acquiror is able
to directly or indirectly exercise voting power, except solely by revocable proxy, would entitle the acquiror to exercise voting power in electing directors within
one of the following ranges of voting power:

•

one-tenth or more but less than one-third;

•

•

one-third or more but less than a majority; or

a majority or more of all voting power.

“Control shares” do not include shares of stock the acquiring person is entitled to vote having obtained prior stockholder approval. Generally, “control

share acquisition” means the acquisition of control shares.

A person who has made or proposes to make a control share acquisition may compel the board of directors to call a special meeting of stockholders to

consider voting rights for the shares. The meeting must be held within 50 days of demand. If no request for a meeting is made, the Company may present the
question at any stockholders’ meeting.

If voting rights are not approved at the meeting or if the acquiring person does not deliver an acquiring person statement as required by the statute, then,

subject to conditions and limitations, the corporation may redeem any or all of the control shares, except those for which voting rights previously have been
approved, for fair value. Fair value is determined without regard to the absence of voting rights for control shares, as of the date of the last control share acquisition
or of any meeting of stockholders at which the voting rights of control shares are considered and not approved. If voting rights for control shares are approved at a
stockholders meeting and the acquiror becomes entitled to vote a majority of the shares entitled to vote, all other stockholders may exercise appraisal rights. The
fair value of the shares as determined for purposes of these appraisal rights may not be less than the highest price per share paid in the control share acquisition.
Limitations and restrictions otherwise applicable to the exercise of dissenters’ rights do not apply in the context of a control share acquisition.

The control share acquisition statute does not apply to shares acquired in a merger, consolidation or share exchange if the company is a party to the

transaction, or to acquisitions approved or exempted by its charter or bylaws. Because the Company is not subject to these provisions, stockholders who acquire a
substantial block of Company common stock do not need approval of the other stockholders before exercising full voting rights with respect to their shares on all
matters. This may make it easier for any of these control share stockholders to effect a business combination with the Company. However, the Company cannot
assure you that any business combinations will be consummated or, if consummated, will result in a purchase of shares of Company common stock from any
stockholder at a premium.

Unsolicited Takeovers

Under certain provisions of the MGCL relating to unsolicited takeovers, a Maryland corporation with a class of equity securities registered under the

Exchange Act and at least three independent directors may elect to be subject, in whole or in part, to certain statutory provisions relating to unsolicited takeovers
which, among other things, would automatically classify the board of directors into three classes with staggered terms of three years each, require two-thirds of all
the votes entitled to be cast by the stockholders generally in the election of directors for the removal of a director, vest in its board of directors the exclusive right to
determine the number of directors and the exclusive right, by the affirmative vote of a majority of the remaining directors, to fill vacancies on the board of
directors, even if the remaining directors do not constitute a quorum and require that a special meeting of stockholders be called at the request of the stockholders
only if requested by stockholders entitled to cast a majority of the votes entitled to be cast at the meeting. These statutory provisions also provide that any director
elected to fill a vacancy shall hold office for the remainder of the full term of the class of directors in which the vacancy occurred, rather than the next annual
meeting of directors as would otherwise be the case, and until his successor is elected and qualified.

An election to be subject to any or all of the foregoing statutory provisions may be made in the Company’s charter or bylaws, or by resolution of the
board of directors without the need for stockholder approval. Any such statutory provision to which the Company elects to be subject will apply even if other
provisions of the Company’s charter or bylaws provide to the contrary, unless the charter or a resolution adopted by the board of directors prohibits such election.

If the Company made an election to be subject to the statutory provisions described above, the board of directors would automatically be classified into

three classes with staggered terms of office of three years each, and would have the exclusive right to determine the number of directors and the exclusive right to
fill vacancies on the board of directors. Moreover, any director elected to fill a vacancy would hold office for the remainder of the full term of the class of directors
in which the vacancy occurred.

In such instance, the classification and staggered terms of office of the directors would make it more difficult for a third party to gain control of the board

of directors since at least two annual meetings of stockholders, instead of one, generally would be required to effect a change in the majority of the board of
directors.

The Company has not elected to become subject to the foregoing statutory provisions relating to unsolicited takeovers. However, the Company could by

resolutions adopted by the board of directors and without stockholder approval, elect to become subject to some or all of these statutory provisions.

Amendment of the Company’s Charter and Bylaws

The Company’s charter may generally be amended only if the amendment is declared advisable by the board of directors and approved by our
stockholders by the affirmative vote of at least two-thirds of the shares entitled to vote on the amendment. The Company’s bylaws generally may be amended by
the affirmative vote of a majority of the board of directors or of a majority of all votes entitled to be cast by the holders of the issued and outstanding shares of
common stock of the Company. However, the following bylaw provisions may be amended only by the approval of a majority of all votes entitled to be cast by the
holders of the issued and outstanding shares of common stock of the Company:

•

•

•

provisions opting out of the control share acquisition statute;

provisions requiring approval by the independent directors for selection of operators of our properties or of transactions involving John B. Kilroy, Sr. and
John Kilroy and their affiliates; and

provisions governing amendment of the Company’s bylaws.

Meetings of Stockholders

The Company’s bylaws provide for annual meetings of its stockholders to elect directors and to transact other business properly brought before the

meeting. In addition, a special meeting of stockholders may be called by:

•

•

•

•

the president;

the board of directors pursuant to a resolution approved by a majority of the entire board of directors;

the chairman of the board; and

the secretary of the Company following, his or her receipt of one or more written demands to call a special meeting of stockholders by holders of at least a
majority of the Company’s issued and outstanding common stock entitled to vote by making a written request.

The MGCL provides that the Company’s stockholders also may act by unanimous written consent without a meeting with respect to any action that they

are required or permitted to take at a meeting. To do so, each stockholder entitled to vote on the matter must sign the consent setting forth the action.

Advance Notice of Director Nominations and New Business Proposals

The Company’s bylaws provide that with respect to an annual meeting of stockholders, nominations of persons for election to the board of directors and

the proposal of other business to be considered by stockholders at the meeting may be made only:

•

•

•

pursuant to the Company’s notice of the meeting;

by or at the direction of the board of directors; or

by a stockholder who is entitled to vote at the meeting and has complied with the advance notice procedures of the Company’s bylaws.

The Company’s bylaws also provide that with respect to special meetings of stockholders, only the business specified in the notice of meeting may be

brought before the meeting.

The advance notice provisions of the Company’s bylaws could have the effect of discouraging a takeover or other transaction in which holders of some,

or a majority, of the shares of common stock might receive a premium

for their shares over the then prevailing market price or which holders of the Company’s common stock believe is in their best interests.

Proxy Access

The Company’s bylaws permit a stockholder, or group of up to twenty stockholders, owning at least 3% of the Company’s issued and outstanding

common stock continuously for at least the prior three years to nominate a candidate for election to the board of directors and inclusion in the Company’s proxy
materials for its annual meeting of stockholders; provided that the total number of all stockholder nominees included in the Company’s proxy materials shall not
exceed 25% of the number of directors then serving on the board of directors. The foregoing proxy access right is subject to additional eligibility, procedural and
disclosure requirements set forth in the Company’s bylaws.

Exclusive Forum for Certain Litigation

The Company’s bylaws provide that, unless the Company consents in writing to the selection of an alternative forum, the Circuit Court for Baltimore

City, Maryland, or, if that court does not have jurisdiction, the United States District Court for the District of Maryland, Baltimore Division, shall be the sole and
exclusive forum for:

•

•

•

•

any derivative action or proceeding brought on behalf of the Company;

any action asserting a claim of breach of any duty owed by any present or former director or officer or other employee or stockholder of the Company to
the Company or the Company’s stockholders or any standard of conduct applicable to the directors of the Company;

any action asserting a claim against the Company or any present or former director or officer or other employee of the Company arising pursuant to any
provision of the MGCL, the Company’s charter or bylaws (in each case, as the same may be amended from time to time); or

any action asserting a claim against the Company or any present or former director or officer or other employee of the Company governed by the internal
affairs doctrine.

Dissolution of the Company

Under the MGCL, the Company may be dissolved if a majority of the entire board of directors declares by resolution that dissolution is advisable and

submits a proposal for dissolution for consideration at any annual or special meeting of stockholders, and this proposal is approved, by the vote of the holders of
two-thirds of the shares of the Company’s capital stock entitled to vote on the dissolution.

Indemnification and Limitation of Liability of Directors and Officers

The Company’s charter and bylaws, and the partnership agreement, provide for indemnification of its officers and directors against liabilities to the fullest

extent permitted by the MGCL, as amended from time to time.

The MGCL permits the Company to indemnify its present and former directors and officers and other parties against judgments, penalties, fines,
settlements, and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made or threatened to be made a party to,
or witness in, by reason of their service in those or other capacities unless it is established that:

•

•

•

the act or omission of the director or officer was material to the matter giving rise to the proceeding and was committed in bad faith or was the result of
active and deliberate dishonesty;

the director or officer actually received an improper personal benefit in money, property or services; or

in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful.

If the proceeding is one by the Company or in its right, indemnification may not be made in respect of any proceeding in which the director or officer has
been found to be liable to the Company. In addition, the Company may not indemnify a director or officer in any proceeding charging improper personal benefit to
them if they were

found to be liable on the basis that personal benefit was received. The termination of any proceeding by judgment, order or settlement does not create a
presumption that the director or officer did not meet the requisite standard of conduct required for indemnification to be permitted. The termination of any
proceeding by conviction, or upon a plea of nolo contendere or its equivalent, or an entry of any order of probation prior to judgment, creates a rebuttable
presumption that the director or officer did not meet the requisite standard of conduct required for indemnification to be permitted.

In addition, the MGCL provides that, unless limited by its charter, a corporation shall indemnify any present or former director or officer who is made a
party to any proceeding by reason of service in that capacity against reasonable expenses incurred by the director or officer in connection with the proceeding, in
the event that the director or officer is successful, on the merits or otherwise, in the defense of the proceeding. The Company’s charter contains no such limitation.

As permitted by the MGCL, the Company’s charter limits the liability of its directors and officers to the Company and its stockholders for money
damages, subject to specified restrictions. However, the liability of the Company’s directors and officers to it and its stockholders for money damages is not limited
if:

•

•

it is proved that the director or officer actually received an improper benefit or profit in money, property or services; or

a judgment or other final adjudication adverse to the director or officer is entered in a proceeding based on a finding that the director’s or officer’s action,
or failure to act, was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding.

This provision does not limit the Company’s ability or its stockholders’ ability to obtain other relief, such as an injunction or rescission.

The partnership agreement provides that the Company, as general partner, and its officers and directors are indemnified to the same extent its officers and

directors are indemnified in its charter. The partnership agreement limits the Company’s liability and the liability of its officers and directors to the operating
partnership and its partners to the same extent that its charter limits the liability of its officers and directors to it and its stockholders. See “Description of Material
Provisions of the Partnership Agreement of Kilroy Realty, L.P.-Indemnification of the Company’s Officers and Directors.”

Insofar as the foregoing provisions permit indemnification of directors, officers or persons controlling the Company for liability arising under the
Securities Act of 1933, as amended, the Securities Act, the Company has been informed that in the opinion of the SEC, this indemnification is against public policy
as expressed in the Securities Act and is therefore unenforceable.

Anti-takeover Effect of Certain Provisions of the MGCL and of the Company’s Charter and Bylaws

If the resolution of the board of directors exempting the Company from the business combination provisions of the MGCL and the applicable provision in

its bylaws exempting it from the control share acquisition provisions of the MGCL are rescinded or revoked (which in each case would require stockholder
approval) or it elects to be subject to the unsolicited takeover provisions of the MGCL, then the business combination, control share acquisition and unsolicited
takeover provisions of the MGCL, the provisions of its charter on removal of directors, the advance notice provisions of its bylaws and certain other provisions of
its charter and bylaws and the MGCL could delay, deter or prevent a change of control of the Company or other transactions that might involve a premium price
for holders of its capital stock or otherwise be in their best interest.

Transfer Agent and Registrar for Shares of Capital Stock

Computershare Shareowner Services LLC is the transfer agent and registrar for shares of the Company’s common stock.
