EXPLANATORY NOTE

This report combines the annual reports on Form 10-K for the year ended December 31, 20192021 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, 2019,2021, the Company owned an approximate 98.1%99.0% common general partnership interest in the Operating Partnership. The remaining approximate 1.9%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 Operating Partnership’s financial statements reflect the noncontrolling interest in Kilroy Realty Finance Partnership, L.P., a Delaware limited partnership (the “Finance Partnership”). This noncontrolling interest represents the Company’s 1% indirect general partnership interest in the Finance Partnership, which is directly held by Kilroy Realty Finance, Inc., a wholly owned subsidiary of the Company. 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, and in the Operating Partnership’s noncontrolling interest in the Finance 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.

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 and Austin, Texas, 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 the Operating Partnership and the Finance PartnershipKilroy Realty, L.P. (the “Operating Partnership”) and generally conduct substantially all of our operations through the Operating Partnership.

We define properties in the tenant improvement phase as office and retaillife 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.

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;properties, as well as our geographic presence in technology and life science market clusters;

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 and redevelopment 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;redevelopment. This includes expansion of our product offering into new submarkets, such as Austin, Texas, where we believe operating and fundamental synergies give us a competitive advantage, as well as in life science properties, which are concentrated in our existing markets; 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 842 (“Topic 842”) 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
7


Measures: Funds From 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 ofintegrate technology to enhance efficiencies with building systems;management systems, security operation centers and tenant experience solutions to provide a premium experience to our tenant base while reducing operating costs;

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, 2019,2021, we had twothree development projects in the tenant improvement phase totaling approximately 846,000 square feet of office and retail space and six projects under construction totaling approximately 2.3 million1,604,000 square feet of office space and 564 residential units.two development projects under construction totaling approximately 946,000 square feet of office and life science space. In addition, ourwe had one redevelopment project under construction totaling approximately 96,000 square feet and two projects committed for life science redevelopment totaling approximately 234,000 square feet. Our future development pipeline was comprised of fivesix potential development sites representing approximately 6159 gross acres of undeveloped land on which we believe we have the potential to develop over 6.05.5 million square feet of office, life science, laboratory, residential and retail space, depending upon economic conditions. Our strategy with respect to development and redevelopment 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 and in Austin, Texas with a focus on design and environment;

maintain a disciplined approach by commencing development when appropriate based on market conditions, focusing on pre-leasing,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;redevelopment when possible;

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

8


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 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 opportunistically and development and redevelopment opportunities as the result of our extensive experience, strong financial position and ability to access capital.capital and in June 2021 we expanded into Austin, Texas through our acquisition of the Indeed Tower, which is in the tenant improvement phase. We continue to focus on growth opportunities in West Coast and Austin, Texas 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, 2019,2021, our total debt as a percentage of total market capitalization was 28.3%34.4%, which was calculated based on the quoted closing price per share of the Company’s common stock of $83.90$66.46 on December 31, 20192021 (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, unsecured term loan 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 have committedour commitment to achieving carbon neutral operations by year-end 2020.advancing progress toward our sustainability ambitions remains strong. 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 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”) sixeight times and have also earned the highly competitive GRESB “Green Star”5 Star designation in each of the last seveneight years for ranking


in the top 25%20% of companiesrespondents worldwide in sustainability performance. We have been recognized with the US EPA ENERGY STAR® Partner of the Year Sustained Excellence Award for the last fivesix years, NAREIT’s Leader in the Light Award in the Listed Office category for the last sixeight years and NAREIT’s Leader in the Light Most Innovative award in 2018.2018 and 2020. We have also been included on Newsweek’s list of America’s Most Responsible Companies for the past three years. For excellence in creating a diverse, equitable and inclusive culture, we are again 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, includingand the majority of our leases also include 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 foureight times.

We build our current development and redevelopment 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 2.31.0 million square feet of office and life science space of under construction.construction development and redevelopment projects. In addition, an analysis of energy and water performance is included in our standard due 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
11


years, we have significantly enhanced the sustainability profile of our portfolio, ending 20192021 with 64%73% of our properties LEED certified, and 70%76% of our eligible stabilized office properties ENERGY STAR certified and 80% 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, 2019)2021).

We identify climate change as a risk to our business,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 Corporate Social Responsibility and Sustainability Committee (the “Committee”).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 have committed to achieving carbon neutral operations by December 31, 2020.2020, and we achieved this goal. This means that the entirety of our scope 1 and scope 2 emissions will beis offset by this date 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, 2019,2021, our 15 largest tenants in terms of annualized base rental revenues represented approximately 49.6%47.4% of our total annualized base rental revenues, defined as annualized monthly contractual rents from existing tenants as of December 31, 2019.2021. 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.

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, (i) the prior owners of the affected properties conducted remediation of known contamination in the soils on our properties, (ii) we are required to conduct further environmental clean-up and environmental closure activities at certain properties, andor (iii) 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, 2019,2021, we had accrued environmental remediation liabilities of approximately $80.7$75.2 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, treatment of contaminated groundwater in connection with dewatering efforts, performing environmental closure activities, constructing remedial systems and other related costs since wethat are required to dispose of any existing contaminated soil, and sometimes perform other environmental closure or remedial activities,necessary 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 compliance concerns that arose at a property after the review was completed; future laws, ordinances, or regulations
15


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 liabilities arising out of or related to their operations and any related liabilities. non-compliance with environmental laws. As of December 31, 2019,2021, other than routine cleaning materials and chemicals used in routine office operations, approximately 2-4%2-3% of our tenants handled hazardous substances and/or wastes on approximately 1-3%1-2% of the aggregate square footage of our properties as part of their routinebusiness 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 otherwise 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.

Litigation

In 2017, lawsuits wereOn April 5, 2021, DIRECTV, LLC’s successor-in-interest filed suit in San Francisco CountyLos Angeles Superior Court alleging vertical and differential settlementagainst a subsidiary of the Company, seeking a declaratory judgment that the tenant properly exercised a contraction option as to approximately 200,000 rentable square feet of space out of a total of 684,411 rentable square feet leased by it at the Millennium Tower propertyproperties located at 301 Mission Street in San Francisco,2240, 2250 and 2260 East Imperial Highway, El Segundo, California. The Millennium Tower isCompany believes tenant did not owned byvalidly exercise its termination option and therefore all such space remains subject to the terms of the lease through the September 30, 2027 scheduled lease expiration date. The Company butintends to vigorously defend the litigation.

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 proximityCalifornia, greater Seattle, Washington and Austin, Texas and we may therefore be susceptible to oneadverse 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.
17


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.

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, Washington and Texas) 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 most state governments and other authorities have lifted or reduced restrictions, they and others may reinstitute these measures in the future, or impose new, more restrictive measures, if the risks, or the perception of the risks, related to the COVID-19 pandemic worsen at any time, including as a result of the spread of new variants of the virus. If such restrictions remain in place for an extended period of time, we may experience reductions in rents from our tenants. 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,
18


some of the activities of our parking, retail space and co-working tenants are not covered by the exceptions listed above and have been directly disrupted by the COVID-19 pandemic and restrictions intended to prevent its spread and their businesses, and accordingly their ability to make rental payments when due, could be adversely affected by decreased consumer confidence or longer-term changes in consumer demand as a result of the COVID-19 pandemic.

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, as a result of the spread of new variants of the virus, 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, including the spread of new variants of the virus 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;

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;

19


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, including as a result of disruptions in supply chains, 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 ongoing COVID-19 pandemic, including the spread of new variants 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;

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

20


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 Austin, Texas 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, Washington and Austin, Texas, 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, floods 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 Austin, Texas or any decrease in demand for office space resulting from the California or greater Seattle or Austin, Texas 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;

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;
21



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, 2019,2021, our 15 largest tenants represented approximately 49.6%47.4% 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.

DownturnDownturns in tenants’ businesses may reduce our revenues and cash flows. For the year ended December 31, 2019,2021, we derived approximately 98.7%99.4% 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, 2019,2021, as a percentage of our annualized base rental revenue for the stabilized portfolio, 51%56% of our tenants operated in the technology industry, 15%17% in the life science and health care industries, 13%10% in the media industry, 8%7% in the finance, insurance and real estate industries, 5%4% in the professional, business and other services industries and 8%6% 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 5.4%8.1% of the total square footage of our stabilized office properties that was not occupied as of December 31, 2019.2021. In addition, leases representing approximately 7.7%5.8% and 6.8%11.1% of the leased rentable square footage of our properties are scheduled to expire in 20202022 and 2021,2023, respectively. Of the leases scheduled to expire in 20202022 and 2021, 28%2023, 27% and 21%1% of the rentable square footage scheduled to expire was re-leased, respectively, as of December 31, 2019.2021. 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
22


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 (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 may not be able to meet our debt service obligations. As of December 31, 2019, we had approximately $3.6 billion aggregate principal amount of indebtedness, of which $5.1 million in principal payments will be paid during the year ended December 31, 2020. Our total debt at December 31, 2019 represented 28.3% 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, unsecured term loan 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 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, unsecured term loan 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, $150.0 million unsecured term loan 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, the unsecured term loan 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, loan 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 unsecured term loan 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.

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.

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 West Coast properties
23


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, include a commitment to achievingwe achieved carbon neutral operations by December 31, 2020.in 2020 per the commitment we made in 2018. This means that the entirety of our scope 1 and scope 2 emissions will beare now offset by this date 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 achievemaintain carbon neutral operations by our targeted date 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.States and in Austin, Texas. 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 mitigateunderstand 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, includingand the majority of our leases also include a cost recoverrecovery 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 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, 2019,2021, we had accrued environmental remediation liabilities of approximately $80.7$75.2 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 asat 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;

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;
25



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;

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.
26


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 eightnine stabilized office properties, one development project under constructionin the tenant improvement phase and one recently acquired future development project, and on June 22, 2021, we completed the acquisition of a development project in the tenant improvement phase in Austin, Texas. We 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 Austin and other markets outside markets,of California, which could adversely affect our ability to acquire, develop or redevelop properties, or to achieve expected performance.performance and amplify our exposure to the other risks notes above.

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-officenon-office/life science real estate. As a result, if a development project includes non-officenon-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-officenon-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. IfAs such, we decide to wholly own a non-office project and hire a third-party manager, we could beare dependent on that partythese third parties and itstheir 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;

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;
27



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, 2019,2021, we owned fourteen office buildings, one of which is a 734,000 square foot development project in the tenant improvement phase, located on various land parcels and in various regions, which we lease individually on a long-term basis. As of December 31, 2019,2021, we had approximately2.0 1.6 million aggregate rentable square feet, or 15.2%10.1% 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.



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;
28



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.

Future terrorist activity or engagement in war by the United States may have an adverse effect on our financial condition and operating results. Terrorist attacks in the United States and other acts of terrorism or war, may result in declining economic activity, which could harm the demand for and the value of our properties. In addition, the public perception that certain locations are at greater risk for attack, such as major airports, ports and rail facilities, may decrease the demand for and the value of our properties near these sites. A decrease in demand could make it difficult for us to renew or re-lease our properties at these sites at lease rates equal to or above historical rates. Terrorist activities also could directly impact the value of our properties through damage, destruction, or loss, and the availability of insurance for these acts may be less, and cost more, which could adversely affect our financial condition. To the extent that our tenants are impacted by future attacks, their businesses similarly could be adversely affected, including their ability to continue to honor their existing leases.

Terrorist acts and engagement in war by the United States also may adversely affect the markets in which our securities trade and may cause further erosion of business and consumer confidence and spending, and may result in increased volatility in national and international financial markets and economies. Any one of these events may cause a decline in the demand for our office leased space, delay the time in which our new or renovated properties reach stabilized occupancy, increase our operating expenses, such as those attributable to increased physical security for our properties, and limit our access to capital or increase our cost of raising capital.

The enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) will subject us to substantial additional federal regulation. There are significant corporate governance and executive compensation-related requirements that have been, and will in the future be, imposed on publicly-traded companies under the Dodd-Frank Act. Several of these provisions require the SEC to adopt additional rules and regulations in these areas. For example, the Dodd-Frank Act requires publicly-traded companies to give stockholders a non-binding vote on executive compensation and so-called “golden parachute” payments. Our efforts to comply with these requirements have resulted in, and are likely to continue to result in, an increase in expenses and a diversion of management’s time from other business activities. In addition, if stockholders do not vote to approve our executive compensation practices and/or our equity plan amendments, these actions may interfere with our ability to attract and retain key personnel who are essential to our future success. Provisions of the Dodd-Frank Act that directly affect other participants in the real estate and capital markets, such as banks, investment funds and interest rate hedge providers,


could also have indirect, but material, impacts on our business that cannot now be predicted.  In addition, in February 2017, the U.S. President ordered the Secretary of the U.S. Treasury to review certain existing rules and regulations, such as those promulgated under the Dodd-Frank Act; however, the implications of that review are not yet known and none of the rules and regulations promulgated under the Dodd-Frank Act have been modified or rescinded as of the date of this report. Given the uncertainty associated with both the results of the existing Dodd-Frank Act requirements and the manner in which additional provisions of the Dodd-Frank Act will be implemented by various regulatory agencies and through regulations, the full extent of the impact of such requirements on our operations is unclear. Accordingly, the changes resulting from the Dodd-Frank Act may impact the profitability of business activities, require changes to certain business practices, or otherwise 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.

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.

Unfavorable resolution of litigation matters and disputes could have a material adverse effect on our financial condition. From time to time, we are involved in legal proceedings, lawsuits and other claims. We may also be named as defendants in lawsuits allegedly arising out of our actions or the actions of our operators, vendors, contractors, tenants or other contractual parties in which such parties have agreed to indemnify, defend and hold us harmless from and against various claims, litigation and liabilities arising in connection with their respective businesses and/or added as an additional insured under certain insurance policies. An unfavorable resolution of any legal proceeding, lawsuit or other claim could have a negative effect on our financial condition, results of operations, cash flow and the quoted trading price of our securities. Regardless of its outcome, legal proceedings, lawsuits and other claims may result in substantial costs and expenses and significantly divert the attention of our management. There can be no assurance that we will be able to prevail or achieve a favorable settlement or outcome. There can also be no assurance that our insurance or the insurance and/or any contractual indemnities of our operators, vendors, contractors, tenants or other contractual parties will be enough to cover all of our defense costs or any resulting liabilities. In addition, litigation, government proceedings or environmental matters could lead to increased costs or interruption of our normal business operations.

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.



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
29


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

The Audit Committee of our Board of Directors oversees our risk management processes related to cybersecurity. It meets no less frequently than annually with our IT personnel and senior management to discuss recent trends in cyber risks and our strategy to defend our IT networks, business and building systems and information against cyber attacks and intrusions. Under the oversight of the Audit Committee, we implemented our cybersecurity standards and overall program by reference to the National Institute of Standards and Technology (“NIST”) Cyber Security Framework. As part of our overall cybersecurity program:

we have implemented a continuous improvement methodology including, but not limited to, ongoing enhancements to processes and controls, quarterly control reviews, annual policy reviews, annual penetration tests and annual investments in our security infrastructure;

we annually assess our cybersecurity program against the NIST framework and periodically engage an outside consulting firm to conduct the assessment; and

we conduct regular cybersecurity awareness training exercises for our employees and primary on-site providers, including ongoing phishing simulations to raise awareness of spoofed or manipulated electronic communications and other critical security threats.

However, 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.

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, 2019, we had an unsecured revolving credit facility and an unsecured term loan facility bearing interest at variable rates on any amounts drawn and outstanding. These facilities comprised approximately 11.0% of our total outstanding debt at December 31, 2019 and were subject to variable interest rates and therefore subject to interest rate risk. In addition, we may 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.

30

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.

The trading price of our common stock may fluctuate significantly. The trading price of our common stock may fluctuate significantly. BetweenJanuary 1, 2019andFebruary 7, 2020, the closing sale price of Company’s common stock on the New York Stock Exchange, or the NYSE, ranged from a low of $61.44 to a high of $85.25 per share. The trading price of our common stock may fluctuate in response to many factors, including:

actual or anticipated variations in our operating results, funds from operations, cash flows, liquidity or distributions;

our ability to successfully execute on our development plans;

our ability to successfully complete acquisitions and operate acquired properties;

earthquakes;

changes in our earnings estimates or those of analysts;

publication of research reports about us, the real estate industry generally or the office and residential sectors in which we operate;

the failure to maintain our current credit ratings or comply with our debt covenants;

increases in market interest rates;

changes in market valuations of similar companies;

adverse market reaction to any debt or equity securities we may issue or additional debt we incur in the future;

additions or departures of key management personnel;

actions by institutional investors;

speculation in the press or investment community;

high levels of volatility in the credit or equity markets;

general market and economic conditions; and

the realization of any of the other risk factors included in this report.

Many of the factors listed above are beyond our control. These factors may cause the trading price of our common stock to decline, regardless of our financial condition, results of operations, business or prospects. We cannot assure you that the trading price of our common stock or the amount of dividends we pay on our common stock will not decline in the future, and it may be difficult for investors to resell shares of our common stock at prices they find attractive, or at all.



Changes in accounting pronouncements could adversely affect our operating results, in addition to the reported financial performance of our tenants. Uncertainties posed by various initiatives of accounting standard-setting by the Financial Accounting Standards Board (“FASB”) and the SEC, which establish and govern accounting standards for U.S. companies, may change the financial accounting and reporting standards or their interpretation and application of these standards that govern the preparation of our financial statements, including the adoption of the lease accounting standard.

Proposed and/or future changes in accounting standards could have a material impact on our reported financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retroactively, resulting in potentially material restatements of prior period financial statements. Similarly, these changes could have a material impact on our tenants’ reported financial condition or results of operations or could impact our tenants’ business decisions in leasing real estate.

We face risks associated with our tenants and contractual counterparties being designated “Prohibited Persons” by the Office of Foreign Assets Control. Pursuant to Executive Order 13224 and other laws, the Office of Foreign Assets Control of the United States Department of the Treasury (“OFAC”) maintains a list of persons designated as terrorists or who are otherwise blocked or banned (“Prohibited Persons”). OFAC regulations and other laws prohibit conducting business or engaging in transactions with Prohibited Persons (the “OFAC Requirements”). Certain of our loan and other agreements require us to comply with OFAC Requirements. Our leases and other agreements, in general, require the other party to comply with OFAC Requirements. If a tenant or other party with whom we contract is placed on the OFAC list, we may be required by the OFAC Requirements to terminate the lease or other agreement. Any such termination could result in a loss of revenue or a damage claim by the other party that the termination was wrongful.

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, 2019,2021, we estimate that our fivesix future development sites, representing approximately 6159 gross acres of undeveloped land, provide more than 6.05.5 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, 2019.2021. 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 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 executiveboard of directors and senior officers playour Chief Executive Officer, plays a key role in the success of the Company. They areHe is integral to the Company’s success for many reasons, including that eachhe has a strong national orand regional reputation in our industry and investment community. In addition, they havehe 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, 2021, we had approximately $4.1 billion aggregate principal amount of indebtedness, of which $5.6 million in principal payments will be paid during the year ended December 31, 2022. Our total debt at December 31, 2021 represented 34.4% 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
31


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 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 $1.1 billion 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
32


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 would 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, 2021, we had a $1.1 billion 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, 2021. However, we may borrow on the revolving credit facility or incur additional variable rate debt in the future. Interest rates are highly sensitive to many factors that are beyond our control, including general economic conditions and policies of various governmental and regulatory agencies and, in particular, the Federal Reserve Board. If the Federal Reserve Board increases the federal funds rate, overall interest rates will likely rise. Interest rate increases would increase our interest costs for any variable rate debt and for new debt, which could in turn 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
33


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 limited 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 asIf 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, 2019,2021, limited partners owned approximately 1.9%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 our President and Chief Executive Officer has substantial influence over our affairs. John Kilroy is the Chairman of our board of directors and our President and Chief Executive Officer. John Kilroy beneficially owned, as of December 31, 2019,2021, approximately 1.5%1.4% of the total outstanding shares of our common stock. The percentage of outstanding shares of common stock beneficially owned includes 274,256372,957 shares of common stock, 499,245530,913 restricted stock units (“RSUs”) that were vested and held by John Kilroy at December 31, 2019,2021, 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. TheIn connection with the Company’s initial public offering, 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 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
34


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, 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
35


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, 2019,2021, we had approximately $3.6$4.1 billion aggregate principal amount of indebtedness outstanding, which represented 28.3%34.4% 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 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.

The market price of our common stock may be adversely affected by future offerings of debt and equity securities by us or the Operating Partnership. In the future, we may increase our capital resources by offering our debt securities and preferred stock, the Operating Partnership’s debt securities and equity securities and our or the Operating Partnership’s other borrowings. Upon our liquidation, dissolution or winding-up, holders of such debt securities, our preferred stock and Operating Partnership’s equity securities, and lenders with respect to other borrowings by us and the Operating Partnership, will be entitled to receive distributions of our available assets prior to the holders of our common stock and it is possible that, after making distributions on these other securities and borrowings, no assets would be available for distribution to holders of our common stock. In addition, the Operating Partnership’s debt and equity securities and borrowings are structurally senior to our common stock, our debt securities and borrowings are senior in right of payment to our common stock, and any preferred stock we may issue in the future may have a preference over our common stock, and all payments (including dividends, principal and interest) and liquidating distributions on such securities and borrowings could limit our ability to pay dividends or make other distributions to the holders of our common stock. Because any decision to issue securities and make borrowings in the future will depend on market conditions and other factors, some of which may be beyond our control, we cannot predict or estimate the amount, timing or nature of our or the Operating Partnership’s future offerings or borrowings. Such future offerings or borrowings may reduce the market price of our common stock.

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, 2019, 106,016,2872021, 116,464,169 shares of the Company’s common stock were issued and outstanding.

As of December 31, 2019,2021, the Company had reserved for future issuance the following shares of common stock: 2,023,2871,150,574 shares issuable upon the exchange, at the Company’s option, of the Operating Partnership’s common units; approximately 0.41.4 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 1.61.3 million shares issuable upon settlement of time-based RSUs; and a maximum of 1.61.7 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.conditions. The Company has a currently effective registration statement registering 9.210.7 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. In addition, as of December 31, 2019, various forward equity sale agreements remain to be settled for 3,147,110 shares of common stock sold by financial institutions acting as forward purchasers. 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:
36



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 at regular corporate rates;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 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 earnings and profits wouldcould increase. This could increase the dividend income to ourthe Company’s stockholders by reducing any return of capital they received. In some circumstances, wethe 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 ourthe Company’s stockholders. In addition, if a Section 1031 Exchange werewas later to be determined to be
37


taxable, we may be required to amend our tax returns for the applicable year in question, including any information reports we sent ourthe 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 us,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% 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, wethe Company must continually satisfy tests concerning, among other things, the sources of ourits income, the nature and diversification of ourits assets, the amounts we distributeit distributes to ourits stockholders and the ownership of ourits capital stock. If we failthe Company fails to comply with one or more of the asset tests at the end of any calendar quarter, wethe 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 ourits 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 ourthe 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 ourthe Company’s ability to qualify as a REIT, ourits 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.

ITEM 1B.    UNRESOLVED STAFF COMMENTS
The 2017 Tax Legislation has significantly changed the U.S. federal income taxation of U.S. businesses and their owners, including REITs and their stockholders.
Changes made by the 2017 Tax Legislation that could affect us and our stockholders include:



temporarily reducing individual U.S. federal income tax rates on ordinary income; the highest individual U.S. federal income tax rate has been reduced from 39.6% to 37% for taxable years beginning after December 31, 2017 and before January 1, 2026;

permanently eliminating the progressive corporate tax rate structure, which previously imposed a maximum corporate tax rate of 35%, and replacing it with a flat corporate tax rate of 21%;

permitting a deduction for certain pass-through business income, including dividends received by our stockholders from us that are not designated by us as capital gain dividends or qualified dividend income, which will allow individuals, trusts, and estates to deduct up to 20% of such amounts for taxable years beginning after December 31, 2017 and before January 1, 2026;

reducing the highest rate of withholding with respect to our distributions to non-U.S. stockholders that are treated as attributable to gains from the sale or exchange of U.S. real property interests from 35% to 21%;

limiting our deduction for net operating losses arising in taxable years beginning after December 31, 2017 to 80% of REIT taxable income determined without regard to the dividends paid deduction;

generally limiting the deduction for net business interest expense in excess of 30% of a business’ “adjusted taxable income,” except for taxpayers (including most equity REITs) that engage in certain real estate businesses and elect out of this rule (provided that such electing taxpayers must use an alternative depreciation system with longer depreciation periods);

eliminating the corporate alternative minimum tax, for taxable years after December 31, 2017;

requiring us to take into account certain income no later than when we take it into account on applicable financial statements, even if the financial statements take such income into account before it accrues under otherwise applicable Code rules; and

repealing the performance-based compensation exception to the $1 million deduction limit on executive compensation and expanding the scope of employees to whom the limit applies.

The legislation is unclear in many respects and could be subject to potential amendments and technical corrections, as well as interpretations and implementing regulations by the U.S. Treasury Department and IRS, any of which could lessen or increase the impact of the legislation. In addition, it is unclear how these U.S. federal income tax changes will affect state and local taxation, which often uses federal taxable income as a starting point for computing state and local tax liabilities. While some of the changes made by the tax legislation may adversely affect us in one or more reporting periods and prospectively, other changes may be beneficial on a going forward basis.

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, redevelopment properties under construction, undeveloped land, recently completed residential properties not yet stabilized 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 retaillife 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, 2019,2021, we added one completedfour development projectprojects to our stabilized office portfolio consisting of 394,340six buildings totaling 1,109,509 square feet of office and life science space in San Diego and South San Francisco, California and 193 residential units in Hollywood, California. We did not have any properties held for sale at December 31, 2021. As of December 31, 2019,2021, the following properties were excluded from our stabilized portfolio. We did not have any

Our stabilized portfolio also excludes our future development pipeline, which as of December 31, 2019,2021, was comprised of fivesix future development sites, representing approximately 6159 gross acres of undeveloped land.

As of December 31, 2019,2021, all of our properties, development projects and developmentredevelopment projects were owned and all of our business was conducted in the state of California with the exception of eightnine stabilized office properties, one development project under constructionin the tenant improvement phase and one recently acquired future development project located in the state of Washington.Washington and one development project in the tenant improvement phase located in Austin, Texas. All
39


of our properties, development projects and developmentredevelopment projects are 100% owned, excluding four office properties owned by three consolidated property partnerships and two development projects held in Variable Interest Entities (“VIEs”) which we consolidated for financial reporting purposes that were established to facilitate potential Section 1031 transactions.partnerships.

We own our interests in all of our real estate assets through the Operating Partnership and the Finance 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 and life science 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”) or a negotiated amount approximating the tenant’s pro-rata share of real estate taxes, insurance and operating expenses (“Expense Stop”). The tenant pays its pro-rata share of increases in expenses above the Base Year or Expense Stop.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 and life science properties, primarily in the greaterGreater 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.

At December 31, 2021, 41% of our properties were leased to tenants on a triple net basis, 27% were leased to tenants on a modified gross basis and 25% of our properties were leased to tenants on a full service gross basis.

We believe that all of our properties are well maintained and do not require significant capital improvements. As of December 31, 2019,2021, we managed all of our office properties through internal property managers.

PERFORMANCE GRAPH

The following line graph compares the change in cumulative stockholder return on shares of the Company’s common stock to the cumulative total return of the FTSE NAREIT All Equity REIT Index, the Standard & Poor’s 500 Stock Index, and the SNL USBloomberg Office REIT Office Index for the five-year period ended December 31, 2019.2021. We include an additional index, the SNL USBloomberg Office REIT Office Index, to the performance graph since management believes it provides additional information to investors about our performance relative to a more specific peer group. The SNL USBloomberg Office REIT Office Index is a published and widely recognized index that comprises 2223 office equity REITs, including us. The graph assumes the investment of $100 in us and each of the indices on December 31, 20142016 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, 2016, the Company adopted FASB ASU No. 2015-03 and 2015-15 which require deferred financing costs, except costs paid for the unsecured line of credit, to be reclassified as a reduction to the debt liability balance instead of being reported as an asset as historically presented. As a result, total assets and total debt have been adjusted from prior amounts reported to reflect this change for all periods presented.
(2)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, 2019, the consolidated balance sheets included $96.3 million of right of use ground lease assets and $98.4 million of ground lease liabilities.
(3)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).
(4)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.
(5)FFO includes amortization of deferred revenue related to tenant-funded tenant improvements of $19.2 million, $18.4 million, $16.8 million, $13.2 million and $13.3 million for the years ended December 31, 2019, 2018, 2017, 2016 and 2015, respectively.


(6)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 result, cash flows provided by (used in) investing activities have been adjusted from prior amounts reported to reflect this change for all periods presented.
(7)For the year ended December 31, 2016, represents occupancy at December 31, 2016.

Company Overview

We are a self-administered REIT active in premier office, life science and mixed-use submarkets alongin the West Coast.United States. 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 and Austin, Texas, which we believe have strategic advantages and strong barriers to entry. We own our interests in all of our real properties through the Operating Partnership and the Finance Partnership and generally conduct substantially all of our operations through the Operating Partnership. We owned an approximate 98.1% and 98.0%99.0% general partnership interest in the Operating Partnership as of both December 31, 20192021 and 2018, respectively.2020. 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).

20192021 Operating and Development Highlights

2019 wasThroughout 2021, we remained steadfast to our core principles of creating value for our shareholders through development, executing leases, recycling capital into higher growth projects, all while maintaining a terrific year across the Company. We achieved another Company recordstrong balance sheet and elevating our leadership position in annual leasing and continued to create value in our operating and development platforms that we believe will drive future earnings and dividend growth.

ESG.
Leasing.
During 2019, we executed new and renewal leases totaling 1.8 millionsquare feet within our stabilized portfolio with an increase in GAAP rents of 52.3% and an increase in cash rents of 29.6%. Our stabilized office portfolio was 94.6% occupied and 97.0% leased as of December 31, 2019. We also signed approximately 1.7 million square feet of leases in our development portfolio.

Development. We continued to execute on our development program during 2019.2021. We added onefour completed development projectprojects to our stabilized portfolio completed construction on 237totaling 1.1 million rentable square feet of office and life science space and 193 residential units, commenced revenue recognition on the first two phases of a development project in the tenant improvement phase, had one development project progress from the under construction phase to the tenant improvement phase commenced construction on three projects and acquiredtwo development sitesproperties in two transactions for approximately $173.0$622.2 million. 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 2019,2021, we generated gross sales proceeds totalingof approximately $133.8 million$1.12 billion through the sale of twothree office buildings. The taxable gain from the $1.08 billion disposition of one of these office buildings was deferred through a Section 1031 Exchange.

Operating Property Acquisitions.Leasing. We remain a disciplinedDuring 2021, we executed new and opportunistic buyer of office properties and development opportunities and continue to focus on value-add opportunities in West Coast markets populated by knowledge and creative based tenants in a variety of industries, including technology, media, health care, life sciences, entertainment and professional services companies. During 2019, we acquired a 19-building creative office campus in Culver City, California in one transactionrenewal leases totaling 151,9081.2 million square feet within our stabilized portfolio with an increase in GAAP rents of space for a total20.8% and an increase in cash purchase pricerents of approximately $186.0 million.7.0%.

COVID-19 Response

Since March 2020, we have been highly focused on planning for the health and safety of our tenants and employees and preparing our buildings in accordance with the policies, protocols and applicable legal requirements in our regions. We hold our occupants’ health at the highest level of importance and have taken extensive steps to facilitate safe work environments. We engaged an industrial hygienist to assist us in designing new standard operating procedures for our buildings that include, but are not limited to, air filtration, water quality, janitorial products and procedures, social separation and screening during building access and elevator use, the use of personal protective equipment, signage, and management of construction activities. Our buildings have remained open to tenants throughout the pandemic and we have continued to see tenants returning to the workplace throughout 2021. We have been in communication with tenants regarding return to work protocols and safety measures, which meet or exceed local and state government guidelines. Our properties received the highest level of pandemic preparedness review through a third-party who verified that all recommended CDC and WHO measures have been successfully implemented, including on-site air, water and germ testing. Our employees began transitioning back to the office during the three months ended March 31, 2021 and by June 30, 2021, all of our employees had returned to our offices on a full-time basis.

We implemented a rent relief program for the majority of our retail tenants whereby we deferred rent from April 2020 to June 2021 in exchange for an extension of their current lease term for an equivalent number of months at future contractual rental rates. We are no longer offering rent relief to the majority of our retail tenants and we will evaluate any future retail rent relief requests on a specific case-by-case basis and only consider those which have a justifiable financial basis. Additionally, the form of relief provided to retail tenants may vary in the future. We did not create a rent relief program for our office tenants. Instead, we evaluate office rent relief requests on a specific case-by-case basis and only consider those which have a justifiable financial basis.

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. Refer to our accounting policy for uncollectible lease receivables and allowances for tenant and deferred rent receivables in “— Critical Accounting Policies and Estimates”for additional information.

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

For the year ended December 31, 2021, our collections of gross rent billings were consistent with our 2020 collections. Gross rent billings represents the total contractual base rent (including tenant direct-billed parking) and CAM billings before any COVID-19 related rent concessions. We are continuing to monitor the potential impact of the COVID-19 pandemic, including the spread of new variants of the virus and restrictions intended to prevent its spread, including 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. With growing vaccination rates, we have seen increases in physical occupancy at our properties, although recovery could be hindered by persistent or resurgent infection rates, including as a result of the spread of new variants of the virus. 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 and Estimates

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, life science and retail operating properties is our principal source of revenue. We recognize revenue from base rent (fixed lease payments), additional rent (which consists(variable lease payments, which consist 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;
57



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 aour capital asset. During the years ended December 31, 2019, 2018,2021, 2020, and 2017,2019, we capitalized $12.0$37.3 million, $22.5$15.5 million, and $22.0$12.0 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, 2019, 2018,2021, 2020, and 2017,2019, we recognized $19.2$16.5 million, $18.4$22.5 million and $16.8$19.2 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.

When a lease is amended, which may occur from time to time, we need to determine whether (1) an additional right of use not included in the original lease is being granted as a result of the modification, and (2) there is an increase in the lease payments that is commensurate with the standalone price for the additional right of use. If both of those conditions are met, the amendment is accounted for as a separate lease contract. If either of those conditions are not met, the amendment is accounted for as a lease modification . Most of our lease amendments are accounted for as a modification of our operating leases which will likely require us to reassess both the lease term and fixed lease payments, including considering any prepaid or deferred rent receivables relating to the original lease, as a part of the lease payments for the modified lease.

Termination options in some of our leases allow the tenant to terminate the lease, in part or in whole, prior to the end of the lease term under certain circumstances. Termination options require advance notification from the tenant and payment of a termination fee that reimburses us for a portion of the remaining rent under the original lease term and the net book value of lease inception costs such as commissions, tenant improvements and lease incentives. Termination fee income, included in rental income, is recognized on a straight-line basis from the date of the executed termination agreement through lease expiration when the amount of the fee is determinable and collectability of the fee is probable. This fee income is reduced on a straight-line basis by any deferred rent receivable related to the lease.

58


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;

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 if a change in estimate is warranted, 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, 20182020 and 20172019 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

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. 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.

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, theThese 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 considersconsidering the current economic and business environment.environment, including 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. 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.term, and for some tenants may include an offsetting partial allowance for uncollectible accounts related to current tenant and deferred rent receivables that exhibit a certain level of collection risk based on the results of the assessment described above. 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-offwrite-

For tenant and deferred rent receivables associated with leases whose rents are deemed If the collectability determination subsequently changes to being probable of collection for leases for which revenue is recorded based on cash received from the tenant, we may record an allowance under other authoritative GAAP usingresume recognizing revenue, including deferred revenue, on a methodology that incorporates a specific identification analysisstraight-line basis and an aging analysis and considersrecognize incremental revenue related to 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 creditworthinessreinstatement 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. Tenantcumulative deferred rent receivable and deferred rent receivables deemed probable of collection are carried net of allowances for uncollectible accounts, with increases or decreases inrevenue balances, as if revenue had been recorded on a straight-line basis since 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 natureinception 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.lease.

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.

For the years ended December 31, 2019, 20182021 and 2017,2020, we recorded a totalnet 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 0.3%,0.4% and 0.5%, respectively,2.1% of total revenues. In addition, forrevenues, respectively. These amounts were primarily as a result of tenant creditworthiness considerations arising from the yearsCOVID-19 pandemic, and a small portion of the 2020 amounts was restored in 2021 based on changes in collectability assessments. Additional amounts may potentially be restored in future periods as circumstances warrant consistent with our accounting policies. For the year ended December 31, 2019, and 2018, we recorded an additionalincrease 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 0.1% and 0.4%, respectively,0.3% of total revenues related to a note receivable. . 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 $8.4$9.6 million, $7.5$9.0 million and $7.2$8.4 million for the years ended December 31, 2019, 20182021, 2020 and 2017,2019, 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
60


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, 2019, 20182021, 2020 and 2017,2019, we capitalized $1.6$1.3 million, $3.8$0.3 million, and $4.6$1.6 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;

current period operating or cash flow losses combined with a historical pattern or future projection of potential continued operating or cash flow losses at a specific property;

deterioration in rental rates for a specific property as evidenced by sudden significant rental rate decreases or continuous rental rate decreases over numerous quarters, which could signal a continued decrease in future cash flow for that 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;

61


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.properties for the years ended December 31, 2021, 2020 and 2019.

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, 2019, 20182021, 2020 and 2017,2019, we capitalized $25.6$20.7 million, $24.2$21.8 million and $23.2$25.6 million, respectively, of internal costs to our qualifying development and redevelopment 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.

62


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, 2019,2021, 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 FAD per share growth, 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, 2019,2021, 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, 2019,2021, there are certain outstanding share-based compensation awards where the achievement of the performance conditions have not allcondition is yet been met.unknown as the award is still within its performance measurement period. 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, 2019, 2018,2021, 2020, and 20172019 we recorded approximately $18.1$26.2 million, $23.5$23.4 million, and $14.5$18.1 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 $1.6$2.3 million, $2.0 million, and $1.1$1.6 million for the years ended December 31, 2019, 2018,2021, 2020, and 2017,2019, respectively.

Factors That May Influence Future Results of Operations

Development Programand Redevelopment Programs

We believe that a portion of our long-term future growth will continue to come from the completion of our in-process development and redevelopment 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 and redevelopment opportunities and expanded our future development pipeline through targeted acquisitions of development opportunities on the West Coast. This includesCoast and in June 2021, into Austin, Texas with our acquisition of Indeed Tower, which is in the acquisitions of two development sites in two separate transactions for a total cash purchase price of approximately $173.0 million in 2019, as discussed in “—Acquisitions” below.tenant improvement phase.

We have a proactive planning process by which we continually evaluate the size, timing, costs and scope of our development programand redevelopment programs 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 programand redevelopment programs 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,activity.

Consistent with 2020, our development activities were largely unaffected by the COVID-19 pandemic during the year ended December 31, 2021; however, the COVID-19 pandemic, and future restrictions intended to prevent its spread if case rates surge again, as appropriate.a result of the spread of new variants or otherwise, 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.

In-Process Redevelopment

As of December 31, 2019,2021, we had one redevelopment project that was under construction:

12340 El Camino Real, Del Mar, San Diego, California. During the three months ended December 31, 2021, we began the phased redevelopment of this property, comprised of approximately 96,000 square feet, for life science use. We expect to complete redevelopment of the project in the third quarter of 2022 with total estimated redevelopment costs of $40.0 million, inclusive of the depreciated basis of the building. The project is 100% leased to a life science tenant and will have phased commencement dates during 2022.

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, 20192021 and 2018,2020, we capitalized interest on in-process development projects and future development pipeline projects with an average aggregate cost basis of approximately $2.0 billion, and $1.6 billion, respectively, as it was determined these projects qualified for interest and other carrying cost capitalization under GAAP. In the event of an extended cessation of development activities, such projects may potentially no longer qualify for capitalization of interest or other carrying costs. However, a cessation of development activities caused by events outside of our control, such as those as a result of government restrictions aimed at stopping the spread of COVID-19, would not impact our ability to capitalize interest and other carrying costs. For the years ended December 31, 20192021 and 2018,2020, we capitalized $81.2$80.2 million and $68.1$79.6 million, respectively, of interest to our qualifying development and redevelopment projects. For the years ended December 31, 20192021 and 2018,2020, we capitalized $25.6$20.7 million and $24.2$21.8 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 2019,2021, we completed the sale of twothree office properties to unaffiliated third parties for total gross sales proceeds of $133.8 million.$1.12 billion through the sale of three office buildings. The taxable gain from the $1.08 billion disposition of one of these office buildings was deferred through a Section 1031 Exchange. During 2018,2020, we completed the sale of 11one office propertiesproperty to unaffiliated third parties for total gross sales proceeds of $373.0$75.9 million.

The timing of any potential future disposition or strategic venture transactions will depend on market conditions and other factors, including but not limited to our capital needs, the availability of financing for potential buyers (which has been and may continue to be constrained for some potential buyers due to the ongoing COVID-19 pandemic’s impact on economic and market conditions, including the financial markets), and our ability to defer some or all of the taxable gains on the sales. We cannot assure that we will dispose of any additional properties, enter into any additional strategic ventures, or that we will be able to identify and complete the acquisition of a suitable replacement property to effect a Section 1031 Exchange or be able to use other tax deferred structures in connection with our strategy. See the “Liquidity and Capital Resources of the Operating Partnership – Liquidity Sources” section for further information.

Acquisitions
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 and strategic operating properties.properties and land.  We continue to focus on growth opportunities primarily in West Coast markets populated by knowledge and creative basedcreative-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 programand redevelopment programs and selectively evaluate opportunities that we believe have the potential to either add immediate Net Operating Income to our portfolio or play a strategic role in our future growth.

During the year ended December 31, 2019,2021, we acquired one operating property, the land underlying a 19-building creative office campushistorical ground lease and two development sitesproperties in threefour transactions for a total cash purchase price of $359.0 million. During$1.16 billion. We did not acquire any operating or development properties during the year ended December 31, 2018, we acquired four office buildings in two transactions for a total cash purchase price of $257.0 million and a 39-acre development site for approximately $308.2 million.2020. We generally finance our acquisitions through proceeds from the issuance of debt and equity securities, borrowings

WeIn 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
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 2019,2021, the annual cash bonus program was structured to allow the Executive Compensation Committee to evaluate a variety of key quantitative and qualitative metrics at the end of the year and make a determination based on the Company’s and


management’s overall performance. Our Executive Compensation Committee also grants equity incentive awards from time to time that include performance-based and/or market-measure based vesting requirements and time-based vesting requirements. As a result, accrued incentive compensation and compensation expense for future awards may be affected by our operating and development performance, financial results, stock price, performance against applicable performance-based vesting goals, market conditions, liquidity measures, 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, 2019,2021, there was approximately $50.5$23.6 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 2.11.6 years. The $50.5ultimate 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 $23.6 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, 2019.2021. Share-based compensation expense for potential future 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, 2019.2021.

As of December 31, 2019, we believe that the weighted average cash rental rates for our total stabilized portfolio, are approximately 20% below the current average market rental rates. Individual properties within any particular submarket presently may be leased either above, below, or at the current market rates within that submarket, and the average rental rates for individual submarkets may be above, below, or at the average cash rental rate of our portfolio.2021.

Our rental rates and occupancy are impacted by general economic conditions, including the pace of regional economic growth and access to capital. Therefore, we cannot give any assurance that leases will be renewed or that available space will be re-leased at rental rates equal to or above the current market rates. In addition, although we believe the weighted average cash rental rates for our stabilized portfolio are generally below current market rates in many of our markets, we are currently unable to provide further comparative information at December 31, 2021 due to the relatively low level of recent transaction volume in our markets as a result of the COVID-19 pandemic.

As restrictions intended to prevent the spread of COVID-19 began to be lifted during the year ended December 31, 2021, we started to see an increase in prospective tenant tours and inquiries and leasing activity compared to 2020 levels. While we do not believe that our development leasing and ability to renew leases scheduled to expire has been significantly impacted by the COVID-19 pandemic, we do believe that the impact of the restrictions and social distancing guidelines and the economic uncertainty caused by the COVID-19 pandemic has impacted the timing and volume of leasing and may continue to do so in the future, particularly if case rates surge again, as a result of the spread of new variants or otherwise. Additionally, decreased demand, increased competition (including sublease space available from our tenants) and other negative trends or unforeseeable events that impair our ability
69


to timely renew or re-lease space could have further negative effects on our future financial condition, results of operations, and cash flows.

Stabilized Portfolio Information

As of December 31, 2019,2021, our stabilized portfolio was comprised of 112120 office and life science properties encompassing an aggregate of approximately 13.515.5 million rentable square feet and 2001,001 residential units at our residential tower in Hollywood, California.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, redevelopment projects under construction, undeveloped land recently completed residential properties not yet stabilized 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 retaillife 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 orproperties held for sale properties at December 31, 2019.2021. Our stabilized portfolio also excludes our future development pipeline, which as of December 31, 20192021 was comprised of fivesix potential development sites, representing approximately 6159 gross acres of undeveloped land on which we believe we have the potential to develop more than 6.05.5 million rentable square feet, depending upon economic conditions.

Results of Operations

Comparison of the Year Ended December 31, 20192021 to the Year Ended December 31, 20182020

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” subsequent to the adoption of Topic 842 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).

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

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

Same Store Properties – includes the consolidated results of all of the office properties that were owned and included in our stabilized portfolio for two comparable reporting periods, i.e., owned and included in our stabilized portfolio as of January 1, 2020 and still owned and included in the stabilized portfolio as of December 31, 2021, including our 200-unit residential tower in Hollywood, California;

2018 and still owned and included in the stabilized portfolio as of December 31, 2019, including our residential tower in Hollywood, California;

Capitalized interest and deferred financing costs increased $13.2 million, or 19.4%,remained generally consistent for the year ended December 31, 20192021 compared to the year ended December 31, 2018, primarily attributable toan increase in the average development asset balances qualifying for interest capitalization during 2019 as compared to 2018.2020. During the years ended December 31, 20192021 and 2018,2020, we capitalized interest on in-process development and redevelopment projects and future development pipeline projects with an average aggregate cost basis of approximately $2.0 billionbillion. In the event of an extended cessation of development or redevelopment 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 or redevelopment 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 $1.6 billion, respectively.other carrying costs.

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, 20192021 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 redevelop existing properties, to make acquisitions of properties or portfolios of properties, or for general corporate purposes.

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

Liquidity Highlights

As of December 31, 2021, we had approximately $414.1 million in cash and cash equivalents. As of the date of this report, we had$1.1 billionavailable under our unsecured revolving credit facility and our next debt maturity occurs in December 2024. We believe that our available liquidity demonstrates a strong balance sheet and makes us well positioned to navigate any additional future uncertainties. In addition, the Company is a well-known seasoned issuer and has historically been able to raise capital on a timely basis in the public markets, as well as the private markets. Any future financings, however, will depend on market conditions for both capital raises and the investment of such proceeds and there can be no assurances that we will successfully obtain such financings.

Distribution Requirements

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

The Company intends to continue to make, but has not committed to make, regular quarterly cash distributions to common stockholders, and through the Operating Partnership, to common unitholders from the Operating Partnership’s cash flow from operating activities. All such distributions are at the discretion of the Board of Directors.Directors. In 2019,2021, 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 minimize its obligation to pay income and excise taxes, it will continue to evaluate whether the current levels of distribution are sufficientappropriate to do so for 2020.throughout 2022. 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 (or in the event additional legislation is enacted that further modifies or repeals laws with respect to Section 1031 Exchanges), the Company may electbe required to distribute a special dividend to its common stockholders and common unitholders in order to minimize or eliminate income taxes on such gains. The Company considers market factors and its performance in addition to REIT requirements in determining its distribution levels. Amounts accumulated for distribution to stockholders are invested primarily in interest-bearing accounts and short-term interest-bearing securities, which is consistent with the Company’s intention to maintain its qualification as a REIT. Such investments may include, for example, obligations of the Government National Mortgage Association, other governmental agency securities, certificates of deposit, and interest-bearing bank deposits.

On December 10, 2019,16, 2021, the Board of Directors declared a regular quarterly cash dividend of $0.485$0.52 per share of common stock. The regular quarterly cash dividend is payable to stockholders of record on December 31, 20192021 and a corresponding cash distribution of $0.485$0.52 per Operating Partnership units is payable to holders of the Operating Partnership’s common limited partnership interests of record on December 31, 2019,2021, including those owned by the Company. The total cash quarterly dividends and distributions paid on January 15, 202012, 2022 were $52.4$61.2 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.

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 and term loan 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.securities, although there can be no assurance in this regard.

20192021 Capital and Financing Transactions

We continue to be active in the capital markets and our capital recycling program to finance potential acquisitions and our acquisition and development activity, andas well as our continued desire to extend our debt maturities. This was primarily a result of the following activity:

Capital Recycling Program

As discussed in the section “Factors That May Influence Future Results of Operations - Capital Recycling Program,” we continuously evaluate opportunities for the potential disposition of properties and undeveloped land in our portfolio or the formation of strategic ventures with the intent of recycling the proceeds generated from the disposition of less strategic or core assets into capital used to finance development and redevelopment 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, 2019,2021, we completed the sale of three properties in two propertiestransactions to unaffiliated third parties for gross sales proceeds totaling approximately $133.8 million.$1.12 billion through the sale of three office buildings. The taxable gain from the $1.08 billion disposition of one of these office buildings was deferred through a Section 1031 Exchange. The proceeds from the sale were used to fund the acquisition of one operating property, the land underlying a historical ground lease and two development property acquisitions totaling $1.2 billion. During 2018,2020, we completed the sale of 11 office propertiesone property to an unaffiliated third partiesparty for total gross sales proceeds of $373.0totaling approximately $75.9 million. See “—Factors that May Influence Future Operations” and Note 4 “Dispositions” to our consolidated financial statements included in this report for additional information.

We currently anticipate that in 20202022 we could raise additional capital through our dispositions program ranging from approximately $150$200 million to $300$500 million. However, 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 acquisitionacquisitions of suitable replacement properties to effect Section 1031 Exchanges to defer some or all of the taxable capital 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.

Settlement of 2018 Common Stock Forward Equity Sale Agreements

In July 2019, the Company physically settled the forward equity sale agreements entered into in August 2018 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. 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 Program

Under our 2018 At-The-Market-Program (the “2018 At-The-Market Program”),current at-the-market stock offering program, which commenced June 2018, we may offer and sell shares of our common stock with an aggregate gross sales price of up to $500.0 million from time to time in “at-the-market” offerings. In connection with the at-the-market program, the Company may also, at its discretion, enter into forward equity sale agreements with certain financial institutions acting as forward purchasers whereby, at our discretion, the forward purchasers may borrow and sell shares of our common stock under our at-the-market program (see “Note 13. Stockholders’ Equity of the Company” to our consolidated financial statements included in this report for additional information).

The weighted average forward sale price that we expect to receive upon physical settlement of the agreements will be subject to adjustment for (i) a floating interest rate factor equal to a specified daily rate less a spread, (ii) the forward purchasers’ stock borrowing costs and (iii) scheduled dividends during the term of the agreements.

We have no obligation to sell the remaining shares available for sale under this program.

Shelf Registration Statement

As discussed above under “—Liquidity and Capital Resources of the Company,” theThe Company is a well-known seasoned issuer and the Company and the Operating Partnership have an effective shelf registration statement that provides for the public offering and sale from time to time by the Company of its preferred stock, common stock, depository shares and guarantees of debt securities and by the Operating Partnership of its debt securities, in each case in unlimited amounts. The Company evaluates the capital markets on an ongoing basis for opportunities to raise capital, and, as circumstances warrant, the Company and the Operating Partnership may issue securities of all of these types in one or more offerings at any time and from time to time on an opportunistic basis, depending upon, among other things, market conditions, available pricing and capital needs. Capital raising could be more challenging under current market conditions than those prior to COVID-19, particularly if case rates surge again. When the Company receives proceeds from the sales of its preferred or common stock, it generally contributes the net proceeds from those sales to the Operating Partnership in exchange for corresponding preferred or common partnership units of the Operating Partnership. The Operating Partnership may use these proceeds and proceeds from the sale of its debt securities to repay debt, including borrowings under its unsecured revolving credit facility, to develop new or redevelop existing properties, to make acquisitions of properties or portfolios of properties, or for general corporate purposes. In September 2019, the Company filed with the Securities Exchange Commission a new shelf registration statement on Form S-3 which became immediately effective upon filing.

Other Liquidity UsesDistribution Requirements

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

The Company intends to continue to make, but has not committed to make, regular quarterly cash distributions to common stockholders, and through the Operating Partnership, to common unitholders from the Operating Partnership’s cash flow from operating activities. All such distributions are at the discretion of the Board of Directors. In 2021, 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 throughout 2022. In addition, in the event the Company is unable to successfully complete Section 1031 Exchanges to defer some or all of the taxable gains related to property dispositions (or in the event additional legislation is enacted that further modifies or repeals laws with respect to Section 1031 Exchanges), the Company may be required to distribute a special dividend to its common stockholders and common unitholders in order to minimize or eliminate income taxes on such gains. The Company considers market factors and its performance in addition to REIT requirements in determining its distribution levels. Amounts accumulated for distribution to stockholders are invested primarily in interest-bearing accounts and short-term interest-bearing securities, which is consistent with the Company’s intention to maintain its qualification as a REIT. Such investments may include, for example, obligations of the Government National Mortgage Association, other governmental agency securities, certificates of deposit, and interest-bearing bank deposits.

On December 16, 2021, the Board of Directors declared a regular quarterly cash dividend of $0.52 per share of common stock. The regular quarterly cash dividend is payable to stockholders of record on December 31, 2021 and a corresponding cash distribution of $0.52 per Operating Partnership units is payable to holders of the Operating Partnership’s common limited partnership interests of record on December 31, 2021, including those owned by the Company. The total cash quarterly dividends and distributions paid on January 12, 2022 were $61.2 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.

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

Capital Recycling Program

As discussed in the section “—Factors“Factors That May Influence Future Results of Operations - Acquisitions,Capital Recycling Program,we continuecontinuously evaluate opportunities for the potential disposition of properties and undeveloped land in our portfolio or the formation of strategic ventures with the intent of recycling the proceeds generated from the disposition of less strategic or core assets into capital used to evaluate strategic opportunities and remain a disciplined buyer offinance development and redevelopment opportunities as well as value-addexpenditures, 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, 2021, we completed the sale of three properties in two transactions to unaffiliated third parties for gross sales proceeds totaling approximately $1.12 billion through the sale of three office buildings. The taxable gain from the $1.08 billion disposition of one of these office buildings was deferred through a Section 1031 Exchange. The proceeds from the sale were used to fund the acquisition of one operating properties, dependentproperty, the land underlying a historical ground lease and two development property acquisitions totaling $1.2 billion. During 2020, we completed the sale of one property to an unaffiliated third party for gross sales proceeds totaling approximately $75.9 million. See “—Factors that May Influence Future Operations” and Note 4 “Dispositions” to our consolidated financial statements included in this report for additional information.

We currently anticipate that in 2022 we could raise additional capital through our dispositions program ranging from approximately $200 million to $500 million. However, any potential future disposition transactions and the timing of any potential future capital recycling transactions will depend on market conditions and business cycles, among other factors.  Wefactors including but not limited to our capital needs, the availability of financing for potential buyers (which has been and may continue to focusbe constrained for some potential buyers due to the ongoing COVID-19 pandemic’s impact on growth opportunities in West Coast markets populated by knowledgeeconomic and creative based tenants in a varietymarket conditions, including the financial markets), and our ability to defer some or all of industries, including technology, media, healthcare, life sciences, entertainment and professional services.  Any material acquisitionsthe taxable gains on the sales. In addition, we cannot assure you that we will dispose of any additional properties or that we will be funded with borrowings underable 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 debt or equity securities,unsecured debt.

At-The-Market Stock Offering Program

Under our current at-the-market stock offering program, which commenced June 2018, we may offer and sell shares of our common stock with an aggregate gross sales price of up to $500.0 million from time to time in “at-the-market” offerings. In connection with the disposition of assets under our capital recyclingat-the-market 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 weCompany may enter into inforward equity sale agreements with certain financial institutions acting as forward purchasers whereby, at our discretion, the future will be completed.

Share Repurchases

An aggregate of 4,935,826 shares currently remain eligible for repurchase under a share repurchase program approved by the Company’s board of directors in 2016. Under this program, repurchasesforward purchasers may be made in open market transactions at prevailing prices or through privately negotiated transactions. We may elect to repurchaseborrow 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 programreport for additional information). The use of a forward equity sale agreement allows the Company to lock in a share price on the future depending upon various factors, including market conditions, the trading pricesale of shares of our common stock at the time the agreement is executed but defer settling the forward equity sale agreements 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 withreceiving the proceeds from property dispositions.the sale of shares until a later date. The Company did not have any outstanding forward equity sale agreements to be settled at December 31, 2021.

Potential Future Leasing CostsSince commencement of our current at-the-market program, we have completed sales of 3,594,576 shares of common stock through December 31, 2021. As of December 31, 2021, we may offer and Capital Improvementssell shares of our common stock having an aggregate gross sales price up to approximately $214.2 million under this program.

Unsecured Senior Notes - Registered Offering

In October 2021, the Operating Partnership issued $450.0 million aggregate principal amount of 2.650% senior notes due 2033 in a registered public offering. Interest on the notes is payable semi-annually at a rate of 2.650% per annum on May 15 and November 15 each year, commencing on May 15, 2022, and the notes mature on August 15, 2033.

Capital expenditures per square foot decreased in 2019 as compared to 2018 due to a decrease in general building improvements during 2019. We currently anticipate capital expenditures for 2020 to be more consistent with 2018 levels. Replacement tenant improvements and leasing commissions increased in 2019 as compared to 2018 primarily due to the number of large leases commenced and related higher replacement costs in 2019. Renewal tenant improvements and leasing commissions per square foot decreased in 2019 as compared to 2018 primarily due to a higher number of large leases renewed in the San Francisco Bay Area and Greater Seattle regions in 2018. We currently anticipate tenant improvement and leasing commissions for 2020 to be higher than 2019 levels due to the leases executed in 2019, including early renewals of 2020 lease expirations; however, ultimate costs incurred will depend upon market conditions in each of our submarkets and actual leasing activity.

Distribution Requirements

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

The Company intends to continue to make, but has not committed to make, regular quarterly cash distributions to common stockholders, and through the Operating Partnership, to common unitholders from the Operating Partnership’s cash flow from operating activities. All such distributions are at the discretion of the Board of Directors. In 2021, 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 throughout 2022. In addition, in the event the Company is unable to successfully complete Section 1031 Exchanges to defer some or all of the taxable gains related to property dispositions (or in the event additional legislation is enacted that further modifies or repeals laws with respect to Section 1031 Exchanges), the Company may be required to distribute a special dividend to its common stockholders and common unitholders in order to minimize or eliminate income taxes on such gains. The Company considers market factors and its performance in addition to REIT requirements in determining its distribution levels. Amounts accumulated for distribution to stockholders are invested primarily in interest-bearing accounts and short-term interest-bearing securities, which is consistent with the Company’s intention to maintain its qualification as a REIT. Such investments may include, for example, obligations of the Government National Mortgage Association, other governmental agency securities, certificates of deposit, and interest-bearing bank deposits.

On December 16, 2021, the Board of Directors declared a regular quarterly cash dividend of $0.52 per share of common stock. The regular quarterly cash dividend is payable to stockholders of record on December 31, 2021 and a corresponding cash distribution of $0.52 per Operating Partnership units is payable to holders of the Operating Partnership’s common limited partnership interests of record on December 31, 2021, including those owned by the Company. The total cash quarterly dividends and distributions paid on January 12, 2022 were $61.2 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.

Liquidity and Capital Resources of the Operating Partnership

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

General

Our primary liquidity sources and uses are as follows:

Liquidity Sources

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

Liquidity Uses

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

General Strategy

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

2021 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:

82


Capital Recycling Program

During the year ended December 31, 2021, we completed the sale of three office buildings in two transactions to unaffiliated third parties for gross sales proceeds totaling approximately $1.12 billion.

Capital Markets / Debt Transactions

In addition to obtaining funding from our capital recycling program during 2021, 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.

Amended and restated the terms of our unsecured revolving credit facility to increase the borrowing capacity from $750.0 million to $1.1 billion, reduce the borrowing costs, extend the maturity date to July 2025, with two six-month extension options, and add a sustainability-linked pricing component whereby the interest rate is lowered by 0.01% if certain sustainability performance targets are met;

Issued $450.0 million aggregate principal amount of 12-year 2.650% green unsecured senior notes due November 2033 in a registered public offering; and

Completed the early redemption of all $300.0 million of the Company’s 3.800% unsecured senior notes due January 2023, resulting in a $12.2 million loss on early extinguishment of debt.

Liquidity Sources

Unsecured Revolving Credit Facility

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

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

As of December 31, 2021 and 2020, $7.3 million and $2.1 million of unamortized deferred financing costs, respectively, which are included in prepaid expenses and other assets, net on our consolidated balance sheets, remained to be amortized through the maturity date of our unsecured revolving credit facility.

83


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

Capital Recycling Program

As discussed in the section “Factors That May Influence Future Results of Operations - Capital Recycling Program,” we continuously evaluate opportunities for the potential disposition of properties and undeveloped land in our portfolio or the formation of strategic ventures with the intent of recycling the proceeds generated from the disposition of less strategic or core assets into capital used to finance development and redevelopment 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, 2021, we completed the sale of three properties in two transactions to unaffiliated third parties for gross sales proceeds totaling approximately $1.12 billion through the sale of three office buildings. The taxable gain from the $1.08 billion disposition of one of these office buildings was deferred through a Section 1031 Exchange. The proceeds from the sale were used to fund the acquisition of one operating property, the land underlying a historical ground lease and two development property acquisitions totaling $1.2 billion. During 2020, we completed the sale of one property to an unaffiliated third party for gross sales proceeds totaling approximately $75.9 million. See “—Factors that May Influence Future Operations” and Note 4 “Dispositions” to our consolidated financial statements included in this report for additional information.

We currently anticipate that in 2022 we could raise additional capital through our dispositions program ranging from approximately $200 million to $500 million. However, any potential future disposition transactions and the timing of any potential future capital recycling transactions will depend on market conditions and other factors including but not limited to our capital needs, the availability of financing for potential buyers (which has been and may continue to be constrained for some potential buyers due to the ongoing COVID-19 pandemic’s impact on economic and market conditions, including the financial markets), and our ability to defer some or all of the taxable gains on the sales. In addition, we cannot assure you that we will dispose of any additional properties or that we will be able to identify and complete the acquisitions of suitable replacement properties to effect Section 1031 Exchanges to defer some or all of the taxable gains related to our capital recycling program. In the event we are unable to complete dispositions as planned, we may raise capital through other sources of liquidity including our available unsecured revolving credit facility or the public or private issuance of unsecured debt.

At-The-Market Stock Offering Program

Under our current at-the-market stock offering program, which commenced June 2018, we may offer and sell shares of our common stock with an aggregate gross sales price of up to $500.0 million from time to time in “at-the-market” offerings. In connection with the at-the-market program, the Company may enter into forward equity sale agreements with certain financial institutions acting as forward purchasers whereby, at our discretion, the forward purchasers may borrow and sell shares of our common stock under our at-the-market program (see “Note 13. Stockholders’ Equity of the Company” to our consolidated financial statements included in this report for additional information). The use of a forward equity sale agreement allows the Company to lock in a share price on the sale of shares of our common stock at the time the agreement is executed but defer settling the forward equity sale agreements and receiving the proceeds from the sale of shares until a later date. The Company did not have any outstanding forward equity sale agreements to be settled at December 31, 2021.

Since commencement of our current at-the-market program, we have completed sales of 3,594,576 shares of common stock through December 31, 2021. As of December 31, 2021, 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. We did not complete any sales under the program during the year ended December 31, 2021.

Shelf Registration Statement

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

Unsecured Senior Notes - Registered Offering

In October 2021, the Operating Partnership issued $450.0 million aggregate principal amount of 2.650% senior notes due 2033 in a registered public offering. Interest on the notes is payable semi-annually at a rate of 2.650% per annum on May 15 and November 15 each year, commencing on May 15, 2022, and the notes mature on August 15, 2033. The Operating Partnership intends to allocate an amount equal to the net proceeds from the offering to one or more eligible green projects. Pending the allocation of an amount equal to the net proceeds from the offering to eligible green projects, a portion of the net proceeds were used to early redeem the $300.0 million aggregate principal amount of our outstanding 3.800% unsecured senior notes that were scheduled to mature on January 15, 2023, and the remaining portion of the net proceeds may be used to redeem or repay indebtedness and, to the extent not used for such purpose, for other general corporate purposes.

Other Liquidity Uses

Development

As of December 31, 2021, we had two development projects under construction.  These projects have a total estimated investment of approximately $1.0 billion of which we have incurred approximately $257.0 million, net of retention, and committed an additional $743.0 million as of December 31, 2021. In addition, as of December 31, 2021, we had three development projects in the tenant improvement phase. These projects have a total estimated investment of approximately $1.2 billion, of which we have incurred approximately $1.1 billion, net of retention, and committed an additional $158.0 million as of December 31, 2021 . We also had three stabilized development projects with a total estimated investment of $900.0 million, of which$100.0 million to $110.0 million remains to be spent in 2022. We had one redevelopment project under construction as of December 31, 2021, with total estimated incremental development costs of approximately $33.4 million, of which we have incurred approximately $21.1 million, net of retention, and committed an additional $12.3 millionas of December 31, 2021. In addition, as of December 31, 2021, we had two projects committed for redevelopment with total estimated incremental redevelopment costs of$36.8 million, of which we have incurred $4.6 million and committed an additional $32.2 million as of December 31, 2021. Including the commitment information in the table above we currently believe we may spend between $550 million to $650 million on development projects throughout 2022. The ultimate timing of these expenditures may fluctuate given construction progress and leasing status of the projects, or
87


as a result of events outside our control, such as delays or increased costs as a result of the COVID-19 pandemic. We expect that any material additional development activities will be funded with borrowings under the unsecured revolving credit facility, the public or private issuance of debt or equity securities, the disposition of assets under our capital recycling program, or strategic venture opportunities. We cannot provide assurance that development projects will be completed on the terms, for the amounts or on the timeliness currently contemplated, or at all.

Debt Maturities

We believe our conservative leverage, staggered debt maturities and recent unsecured line of credit facility amendment provide us with financial flexibility and enhance our ability to obtain additional sources of liquidity if necessary, and, therefore, we believe we are well-positioned to refinance or repay maturing debt and to pursue our strategy of seeking attractive acquisition opportunities, which we may finance, as necessary, with future public and private issuances of debt and equity securities. However, we can provide no assurance that we will have access to the public or private debt or equity markets in the future on favorable terms or at all. Our next debt maturity occurs in December 2024.

Potential Future Acquisitions

During the year ended December 31, 2021, we acquired one operating property, the land underlying a historical ground lease and two development properties in four transactions for a total cash purchase price of $1.16 billion. We did not acquire any operating properties during the year ended December 31, 2020. 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 and strategic operating properties, dependent on market conditions and business cycles, among other factors.  We focus on growth opportunities primarily in markets populated by knowledge and creative based tenants in a variety of industries, including technology, media, healthcare, life sciences, entertainment and professional services.  We expect that any material acquisitions will be funded with borrowings under the unsecured revolving credit facility, the public or private issuance of debt or equity securities, the disposition of assets under our capital recycling program, the formation of strategic ventures or through the assumption of existing debt, although there can be no assurance in this regard.

Share Repurchases

As of December 31, 2021, 4,935,826 shares remained eligible for repurchase under a share repurchase program approved by the Company’s board of directors in 2016. Under this program, repurchases may be made in open market transactions at prevailing prices or through privately negotiated transactions. We may elect to repurchase shares of our common stock under this program in the future depending upon various factors, including market conditions, the trading price of our common stock and our other 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, particularly if case rates surge again, as a result of the spread of new variants or otherwise.

For properties within our stabilized portfolio, excluding our development properties, we believe we could spend approximately $120 million to $130 million in capital improvements, tenant improvements and leasing costs in 2022, 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 2022.

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, 2021, 2020 and 2019 on a per square foot basis.

Capital expenditures per square foot remained consistent in 2021 as compared to 2020. We currently anticipate capital expenditures for 2022 to be consistent with 2021 levels. Replacement tenant improvements and leasing commissions per square foot decreased in 2021 as compared to 2020 primarily due to large leases with long terms commenced in the San Francisco Bay Area and San Diego County regions in 2020. Renewal tenant improvements and leasing commissions per square foot decreased in 2021 as compared to 2020 primarily due to a large lease with a long term renewed in the San Francisco Bay Area in 2020. We currently anticipate tenant improvement and leasing commissions for 2022 to behigher than 2021 levels due to an expected increase in leasing activity as well as the leases executed in prior years; however, ultimate costs incurred will depend upon market conditions in each of our submarkets and actual leasing activity.

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, and the amount of our future borrowings.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:

The Operating Partnership was in compliance with all of its debt covenants as of December 31, 2019.2021. Our current expectation is that the Operating Partnership will continue to meet the requirements of its debt covenants in both the short and long term. However, in the event of an economic slowdown or continued volatility in the credit markets, there is no certainty that the Operating Partnership will be able to continue to satisfy all the covenant requirements.

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 following table presents our FFO for the years ended December 31, 2021, 2020, 2019, 2018 and 2017:

Inflation

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 We did not adopt any 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 consolidated financial statements as of and foraccounting pronouncements during the year ended December 31, 2019, and will be included in the Report of Independent Registered Public Accounting Firm for the Operating Partnership’s financial statements as of and for the year ending December 31, 2020.2021.

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, 20192021 and 2018,2020, we did not have any interest-rate sensitive derivative assets or liabilities. Information about our changes in interest rate risk exposures from December 31, 20182020 to December 31, 20192021 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, 2019, 11.0%2021, 100.0% of our total outstanding debt of $3.6$4.1 billion (before the effects of debt discounts and deferred financing costs) was subject to variable interest rates. The remaining89.0% bore interest at fixed rates.rates since our only variable-rate debt instrument was our unsecured revolving credit facility which had no outstanding balance at December 31, 2021. 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 line ofrevolving 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 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 revolving credit facility 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. 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, 2019 and December 31, 2018.

At December 31, 2019, the total outstanding balance of our variable-rate debt was comprised of borrowings on our unsecured revolving 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. As of December 31, 2018, the total outstanding balance of our variable-rate debt was comprised of borrowings on our unsecured revolving credit facility of $45.0 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 3.48%) and LIBOR plus a spread of 1.10% (weighted average interest rate of 3.49%), respectively. Assuming no changes in the outstanding balance of our existing variable-rate debt as of December 31, 2019, a 100 basis point increase in the LIBOR rate would have increased our projected annual interest expense, before the effect of capitalization, by approximately $4.0 million.

The total carrying value of our fixed-rate debt was approximately $3.2 billion and $2.7 billion as of December 31, 2019 and 2018, respectively. The total estimated fair value of our fixed-rate debt was approximately $3.4 billionand $2.7 billion as of December 31, 2019 and 2018, 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 $203.3 million, or 6.0%, as of December 31, 2019. 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 $165.3 million, or 6.1%, as of December 31, 2018.




In July 2017, 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 after 2021.by June 30, 2023. 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. The replacement provisions of our unsecured revolving credit facility permit the use of rates based on SOFR.

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, 2021 and December 31, 2020.

At December 31, 2021, there was no outstanding balance on our $1.1 billion unsecured revolving credit facility; however, it was available for borrowing at the following variable rate: LIBOR plus a spread of 0.90% (weighted average interest rate of1.00%). As of December 31, 2020, there was no outstanding balance on our variable-rateunsecured 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%).

The total carrying value of our fixed-rate debt is indexedwas approximately $4.1 billion and $3.9 billion as of December 31, 2021 and 2020, respectively. The total estimated fair value of our fixed-rate debt was approximately $4.4 billion
94


as of December 31, 2021 and 2020, respectively. For sensitivity purposes, a 100 basis point increase in the discount rate equates to LIBOR, we are monitoring this activity and evaluatinga decrease in the related risks.total fair value of our fixed-rate debt of approximately $262.7 million, or 6.0%, as of December 31, 2021. 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 $264.2 million, or 6.0%, as of December 31, 2020.

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, 20192021 and 2018,2020, the related consolidated statements of operations, equity, and cash flows, for each of the three years in the period ended December 31, 2019,2021, 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, 20192021 and 2018,2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019,2021, 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, 2019,2021, 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 13, 202010, 2022, 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 andrelated to tenant funded improvements — Ownership of Tenant Improvements -tenant improvements and timing of development property revenue recognition — Refer to Notes 2 and 10 to the financial statements

Critical Audit Matter Description
The timing of when the Company evaluates tenant improvementscommences rental revenue recognition depends largely on a lease-by-lease basis to determinethe Company’s determination of who is the owner of such assetsthe 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 typicallygenerally when the improvements being recorded as the Company’s asset 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 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, and rentallease. Rental revenue recognition begins when


the tenant takes possession of or controls the leased space. The determination of whether the Company or tenant is the owner of tenant improvements for accounting purposes is subject to significant judgment, and the commencement of rental revenue recognition depends on the Company’s conclusion as to 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 of its obligations under the lease agreement in order for the leased space to be used by the tenant as intended.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.

Given the nature of construction work on large development properties, auditing management’s estimates regarding the commencement of rental revenue recognition, including the determination of the owner of the tenant improvements and when control of the leased space transfers to the tenant, involves especially subjective judgment. 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, typically dependent uponmanagement considers numerous factors and performs a detailed evaluation of each individual lease. No one factor is determinative in reaching a conclusion and the judgmentfactors 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 to evaluate the nature of tenant improvements, particularly the uniqueness of the improvements.
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 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.

Testing documentation from construction contractors, architects, and city building inspection sign offs on temporary certificates of occupancy.

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, 2019,2021, 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 13, 2020,10, 2022, 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 related to tenant funded improvements — Ownership of tenant improvements and timing of development property revenue recognition — 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 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
F - 8


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.

Partially Owned Entities and Variable Interest Entities

At December 31, 20192021 and 2020, the consolidated financial statements of the Company included 42 VIEs in addition to the Operating Partnership: 2 of the consolidated property partnerships, 100 First LLC and 303 Second LLC, and 2 entities established during the fourth quarter of 2019 to facilitate potential future Section 1031 Exchanges.LLC. At December 31, 2019,2021 and 2020, the Company and the Operating Partnership were determined to be the primary beneficiaries of these 42 VIEs since we had the ability to control the activities that most significantly impact each of the VIEs’ economic performance. As of December 31, 2019,2021, the 42 VIEs’ total assets, liabilities and noncontrolling interests included on our consolidated balance sheet were approximately $676.7$462.3 million (of which $598.0$377.9 million related to real estate held for investment), approximately $40.1$28.1 million and approximately $189.6$190.7 million, respectively. At December 31, 2020, the 2 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 on our consolidated balance sheet), 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, 2018, the consolidated financial statements of the Company included 3 VIEs in addition to the Operating Partnership: 2 of the consolidated property partnerships, 100 First LLC and 303 Second LLC, and an entity established during the fourth quarter of 2018 to facilitate a Section 1031 Exchange. At December 31, 2018, the Company and the Operating Partnership were determined to be the primary beneficiaries of these 3 VIEs since we had the ability to control the activities that most significantly impact each of the VIEs’ economic performance. At December 31, 2018, the 3 VIEs’ total assets, liabilities and noncontrolling interests included on our consolidated balance sheet were approximately $615.4 million (of which $543.9 million related to real estate held for investment on our consolidated balance sheet), approximately $45.1 million and approximately $186.4 million, respectively. In January 2019, the Section 1031 Exchange was successfully completed and the related VIE was terminated.

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, 20192021 or 2018.2020.

Accounting Pronouncements Adopted January 1, 2019

Effective January 1, 2019, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2016-02 “Leases (Topic 842)” (“Topic 842”) and the related FASB ASU Nos. 2018-01, 2018-10, 2018-11, 2018-20 and 2019-01 which provide practical expedients, technical corrections and improvements for certain aspects of ASU 2016-02, on a modified retrospective basis. Topic 842 establishes a single comprehensive model for entities to use in accounting for leases and supersedes the existing leasing guidance. We evaluated each of the Company’s contracts to determine if the contract is or contains a lease and concluded that Topic 842 is applicable to the Company as a lessor in its tenant lease agreements and as a lessee in its ground leases.

COVID-19 Lease Modification Accounting Relief
Lessor Accounting
As a lessor,The global impact of the Company’s leases with tenants for its real estate assets generally provide forCOVID-19 pandemic continues to evolve rapidly. In 2020, all of the leasestates where we own properties and/or have development projects, reacted to the COVID-19 pandemic by instituting quarantines, restrictions on travel, “shelter in place” rules, restrictions on types of space,business that may continue to operate and/or restrictions on types of construction projects that may continue. While most of these restrictions were lifted in 2021, the COVID-19 pandemic continued to have an impact on our business, as well as common area maintenancethat of our tenants.

Due to the business disruptions and parking. Under Topic 842,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 of space is considered a lease component while the common area maintenance billings and tenant parking are considered nonlease components, which fall under revenue recognitionmodification guidance in FASB Accounting Standards Codification (“ASC”) Topic 606 “Revenue from Contracts with Customers”842 (“Topic 606”842”). However, upon adopting addresses routine changes to lease terms resulting from negotiations between the lessee and the lessor, this guidance in Topic 842,did not contemplate concessions being so rapidly executed to address the Company determined thatsudden liquidity constraints of some lessees arising from the COVID-19 pandemic and restrictions intended to prevent its tenant leases metspread.

In April 2020, the criteria to apply the practical expedient provided by ASU 2018-11 to recognize the leaseFASB staff issued a question and non-lease components together as one single component. This conclusion was basedanswer document (the “Lease Modification Q&A”) focused on the consideration that 1) the timing and patternapplication of transfer of the nonlease components and associated lease component are the same, and 2) theaccounting guidance to lease component, if accounted for separately, would be classified as an operating lease. As the lease of space is the predominant component of the Company’s leasing arrangements, we accounted for all lease and non-lease components as one single component under Topic 842. As a result, the adoption of Topic 842 did not have any impact on the Company’s timing or pattern of recognition of rental revenues as compared to previous guidance. Transient daily parking revenue is accounted for under the guidance in Topic 606 and included in other property income in our consolidated statements of operations.
To reflect their recognition as one lease component, base rental revenues, additional rental revenues (which consist of amounts due from tenants for common area maintenance, real estate taxes, and other recoverable costs) and other lease related property income related to leases that also meet the requirements of the practical expedientconcessions provided by ASU 2018-11 have been combined in one line item subsequent to the adoption of Topic 842 for the year ended December 31, 2019 in rental income on the Company’s consolidated statements of operations. In addition, under Topic 842, lessor costs for certain services directly reimbursed by tenants, which were previously presented on a net basis under previous guidance, are required to be presented on a gross basis in revenues and expenses. During the year ended December 31, 2019, we incurred additional property expenses of $13.9 million for which we were reimbursed, that were not required to be grossed up under the previous guidance. We presented this amount on a gross basis within rental income and property expenses in the Company’s consolidated statements of operations as a result of the adoption, which had no impactCOVID-19 pandemic. Under existing lease guidance, the Company would have to determine, on net income.

Our rental income is mostly compriseda lease by lease basis, if a lease concession was the result of fixed contractual payments defineda 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 that, in most cases, escalate annually overagreement (precluded from applying the termlease 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 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 at fixed rates. Additionally, rental income includes variable payments for tenant reimbursements of property-related expenses and payments based on a percentage of tenant’s sales.

Upon the adoption of Topic 842 on January 1, 2019, the method for recognizing revenue includes a binary assessment of whether or not substantially all of the amounts due under a tenant’sby lease agreement are probable of collection. For leases that are deemed probable of collection, revenue is 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.

In addition, the Company has elected to apply the package of practical expedients provided and did not reassess the following as of January 1, 2019: 1) whether any expired or existing contracts are or contain leases; 2) the lease classification for any expired or existing leases; and 3) initial direct costs for any existing leases. Under Topic 842, initial direct costs for both lessees and lessors would 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, beginning January 1, 2019, the

Company no longer capitalized internal leasing costs and third-party legal leasing costs and instead expensed these costs as incurred. These expenses are included in leasing costs and general and administrative expenses on our consolidated statements of operations in 2019. During the year ended December 31, 2019, the Company expensed approximately $11.4 million of indirect leasing costs which would have been capitalized prior to the adoption of Topic 842.
The election of the package of practical expedients described above permits us to continue to account for our leases that commenced before January 1, 2019 under the previously existing leasemodification accounting guidance for the remainder of their lease terms, and to apply the new lease accounting guidanceframework consistently to leases commencing or modified after January 1, 2019. On January 1, 2019, we recognized a $3.1 million cumulative-effect adjustment, primarily related to internal leasing costs and legal leasing costs for tenant leases that had not commenced prior to that date, to increase distributions in excess of earnings forwithin the Company and partners’ capital for the Operating Partnership in connection with our adoption of Topic 842.
Lessee Accounting
The Company’s ground leases are the primary contractsproperty types in which we are the lessee. Upon adoption of Topic 842 on January 1, 2019, the Company had 4 existing ground leases which were classified as operating leases. As discussed above, the Company elected to apply the package of practical expedients provided by Topic 842it invests, specifically office, life science, residential and therefore did not reassess the classification of these ground leases. Existing ground leases that commenced before the January 1, 2019 adoption date continued to be accounted for as operating leases, and the new guidance did not have a material impact on our recognition of ground lease expense or our results of operations. However, for periods beginning after January 1, 2019, we are now required to recognize a lease liability on our consolidated balance sheets equal to the present value of the minimum future lease payments required in accordance with each ground lease, as well as a right of use asset equal to the lease liability adjusted for above and below market intangibles and deferred leasing costs. To determine the discount rates used to calculate the present value of the lease payments, we used a hypothetical curve derived from unsecured corporate borrowing rates over the lease terms. The weighted average discount rate for our 4 existing ground leases was 5.15%. The adoption of Topic 842 resulted in the recognition of right of use ground lease assets totaling $82.9 million and ground lease liabilities totaling $87.4 million on January 1, 2019. There was no material impact to our consolidated statements of operations or consolidated statements of cash flows as a result of adoption of this new guidance. For further information related to our ground leases, refer to Note 18 “Commitments and Contingencies.”retail properties.

For leases with a term of 12 months or less where we are the lessee, we made an accounting policy election by class of underlying asset not to recognize right of use lease assets and lease liabilities. We recognize lease expense for such leases generally on a straight-line basis over the lease term.

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 (fixed lease payments), additional rent (which consists(variable lease payments, which consist 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.


F - 17




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

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.

When a lease is amended, which may occur from time to time, we need to determine whether (1) an additional right of use not included in the original lease is being granted as a result of the modification, and (2) there is an increase in the lease payments that is commensurate with the standalone price for the additional right of use. If both of those conditions are met, the amendment is accounted for as a separate lease contract. If either of those conditions are not met, the amendment is accounted for as a lease modification. Most of our lease amendments are accounted for as a modification of our operating leases which will likely require us to reassess both the lease term and fixed lease payments, including considering any prepaid or deferred rent receivables relating to the original lease, as a part of the lease payments for the modified lease.

Termination options in some of our leases allow the tenant to terminate the lease, in part or in whole, prior to the end of the lease term under certain circumstances. Termination options require advance notification from the tenant and payment of a termination fee that reimburses us for a portion of the remaining rent under the original lease term and the net book value of lease inception costs such as commissions, tenant improvements and lease incentives. Termination fee income, included in rental income, is recognized on a straight-line basis from the date of notification of early termination through lease expiration when the amount of the fee is determinable and collectability of the fee is probable. This fee income is reduced on a straight-line basis by any deferred rent receivable related to the lease projected at the date of tenant vacancy.

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, 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.

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 ASC Topic 606 “Revenue from Contracts with Customers” 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.

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, theThese 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. If the collectability determination subsequently changes to being probable of collection for leases for which revenue is recorded based on cash received from the tenant, we resume recognizing revenue, including deferred revenue, on a straight-line basis and recognize incremental revenue related to the reinstatement of cumulative deferred rent receivable and deferred revenue balances, as if revenue had been recorded on a straight-line basis since the inception of the lease.

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

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.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)
business combinations at fair value at the acquisition date. Transaction costs associated with asset acquisitions, including costs incurred during negotiation, are capitalized as part ofin 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-partythird-

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


F - 20




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

For office, life science and retail development or redevelopment properties with multiple tenants and stagedphased 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, 2021, 2020, and 2019 2018,was $256.3 million, $244.8 million, and 2017 was $211.9 million, $198.6 million, and $190.5 million, respectively.

Real Estate Assets Held for Sale, Dispositions and Discontinued Operations

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

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, 2019, 20182021, 2020 and 20172019 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 (losses) on sales of depreciable operating properties within continuing operations in the period the landproperty 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

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.taxes and cash investments with original maturities greater than 3 months. As of December 31, 2019, we did not have any restricted cash held at qualified intermediaries for the purpose of facilitating Section 1031 Exchanges. As of December 31, 2018,2020, we had $113.1$74.9 million of restricted cash held at qualified intermediaries for the purpose of facilitating Section 1031 Exchanges. In January 2019,2021, the Section 1031 Exchange was completedterminated and the cash proceeds were released from the qualified intermediary. We did not have any cash held at qualified intermediaries at December 31, 2021.

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, deferredDeferred 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 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 3 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”) and the Company’s 1.0% general partnership interest in the Finance Partnership. The 1.0% general partnership interest in the Finance Partnership noncontrolling interest is presented in the permanent equity section of the Operating Partnership’s consolidated balance sheets given that these interests are not convertible or redeemable into any other ownership interest of the Company or the Operating Partnership. .

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 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 1 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

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

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

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTSLevel 3(Continued)
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 and unsecured line of credit 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 unsecured term loan facility, and unsecured term loan 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 unsecured term loan facility, and unsecured term loan 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 (including any applicable alternative minimum tax) 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, 2019, 20182021, 2020 and 2017,2019, and we were not subject to any federal income taxes (see Note 2524 “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 2019,2020 are subject to federal, state, and local income taxes. For the years ended December 31, 2019, 20182021, 2020 and 20172019 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, 20192021 or 2018.2020. As of December 31, 2019,2021, the years still subject to audit are 20152017 through 20192021 under the California state income tax law and 20162018 through 20192021 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.

Accounting Standards Issued But Not Yet Effective at December 31, 2019

Accounting Pronouncements Adopted January 1, 2020

ASU No. 2016-13 “Financial Instruments - Credit Losses (Topic 326)”
On June 16, 2016, the FASB issued ASU No. 2016-13 (“ASU 2016-13”) to amend 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. 2018-19Codification 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.” ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The adoption did not have a material impact on the consolidated financial statements or notes to the consolidated financial statements.
ASU No. 2018-13 “Fair Value Measurement (Topic 820)”
On August 28, 2018, the FASB issued ASU No. 2018-13 (“ASU 2018-13”) to amend 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, which the Board finalized on August 28, 2018. The Board used the guidance in the Concepts Statement to improve the effectiveness of ASC 820’s disclosure requirements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for any eliminated or modified disclosures. The adoption did not have a material impact on the disclosures in the notes to the consolidated financial statements.
ASU No. 2018-15 “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)”
On August 29, 2018, the FASB issued ASU No. 2018-15 (“ASU 2018-15”) to amend 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). ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. ASU 2018-15 can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The adoption did not have a material impact on the consolidated financial statements or notes to the consolidated financial statements.

Common Units of the Operating Partnership

The Company owned a 98.1% and 98.0%99.0% common general partnership interest in the Operating Partnership as of December 31, 20192021 and 2018, respectively.2020. The remaining 1.9% and 2.0%1.0% common limited partnership interest as of December 31, 20192021 and 2018, respectively,2020 was owned by non-affiliated investors and certain of our executive officers and directors in the form of noncontrolling common units. There were 2,023,287 and 2,025,2871,150,574 common units outstanding held by these investors, executive officers and directors as of December 31, 20192021 and 2020, respectively. 2018, respectively. The decrease in the common units from December 31, 2018 to December 31, 2019 was attributable to 2,000 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 1-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 10 trading days immediately preceding the applicable redemption date. The aggregate value upon redemption of the then-outstanding noncontrolling common units was $167.7$76.2 million and $126.4$65.4 million as of December 31, 20192021 and 2018,2020, 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, 20192021 and 20182020 were $189.6$190.7 million and $186.4$191.9 million, respectively. The remaining amount of noncontrolling interests in consolidated property partnerships represents the third party equity interest in Redwood LLC.

December 2018 Market-Based RSU Grant

In connection with entering into an amended employment agreement (the “Amended Employment Agreement”), on December 27, 2018, the Executive Compensation Committee awarded John Kilroy, the Chairman of the Board of Directors and Chief Executive Officer of the Company and the Operating Partnership, 266,130 RSUs (at the target level of performance) that are subject to market-based vesting requirements, providing an additional retention incentive during the term of the agreement and enticing Mr. Kilroy to delay his retirement. In addition to Mr. Kilroy’s award, the Executive Compensation Committee awarded 80,647 RSUs (at the target level of performance), subject to market-based vesting requirements, to certain members of management (together totaling 346,777 target RSUs with Mr. Kilroy’s award, the “December 2018 Market-Based RSUs”). Between 0% and 200% of 75% of the total 346,777 target number of December 2018 Market-Based RSUs will bebecame eligible to vest based on the Company’s relative total shareholder return (“TSR”) versus a comparative group of companies that consist of companies incomprised what was previously the SNL US REIT Office Index, over the performance period. Anperiod ended December 31, 2021 (consisting of calendar years 2019 through 2021). This 2019-2021 initial TSR market condition was achieved at 0% for all participants. As a result, none of the initial number of RSUs (the “Initial Number of RSUs”) will be determined at the end were earned as

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”). The 2018 Performance-Based RSUs are also subject to a three year service vesting provision 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 2018 FFO Performance Condition was achieved at 175% of target for one participant and 150% of target for all other participants. The number of 2018 Performance-Based RSUs ultimately earned could fluctuate from the current estimated number of 2018 Performance-Based RSUs granted based upon the levels of achievement for the 2018 Debt to EBITDA Ratio Performance Condition, the 2018 Market Condition and the extent to which the service vesting condition is satisfied.

The 2017 Performance-Based RSUs are scheduled to cliff vest at the end of a three year period (consisting of calendar years 2017-2019) based upon (1) the achievement of pre-defined FFO per share goals for the year ended December 31, 2017 that applies to 100% of the 2017 Performance-Based RSUs awarded (the “2017 FFO Performance Condition”) and (2) also based upon either the average FAD per share growth that applies to 30% of the award or the Company’s average debt to EBITDA ratio that applies to a separate 30% of the award (together, the “Other 2017 Performance Conditions” and together with the 2017 FFO Performance Condition, the “2017 Performance Conditions”) or the relative TSR versus a comparative group of companies that consist of companies in the SNL US REIT Office Index that applies to the remaining 40% of the award (the “2017 Market Condition”) for the three year period ending December 31, 2019. Based on the combined results of the 2017 Performance Conditions and the 2017 Market Condition, the 2017 Performance-Based RSUs achieved a weighted average of approximately 131% of their target level of performance.

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 collectability reversals for the years ended December 31, 2021 and 2020:

For the year ended December 31, 2021, the adjustments are reduced by the recognition of deferred rent balances associated with tenants restored from a cash basis of revenue recognition to an accrual basis to revenue recognition.

We have operating leases with tenants that expire at various dates through2043 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.

Environmental Matters

We follow the policy of monitoringevaluating 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 undisclosed 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, 20192021 and 2018,2020, we had accrued environmental remediation liabilities of approximately $80.7$75.2 million and $83.2$71.3 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, treatment of contaminated groundwater in connection with dewatering efforts, performing environmental closure activities, constructing remedial systems, and other related costs since wethat are required to dispose of any existing contaminated soil, and sometimes perform other environmental closure or remedial activities,necessary 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, 20192021 and 20182020 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 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

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.
