DOCUMENTS INCORPORATED BY REFERENCE

Portions of the Kilroy Realty Corporation’s Proxy Statement with respect to its 2021 Annual Meeting of Stockholders to be filed not later than 120 days after the end of the registrant’s fiscal year are incorporated by reference into Part III of this Form 10-K.

EXPLANATORY NOTE

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

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

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

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

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

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

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

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

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

To help investors understand the significant differences between the Company and the Operating Partnership, this report presents the following separate sections for each of the Company and the Operating Partnership:

•Item 6. Selected Financial Data – Kilroy Realty Corporation;

•Item 6. Selected Financial Data – Kilroy Realty, L.P.;

•Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations:

◦—Liquidity and Capital Resources of the Company; and

•consolidated financial statements;

•the following notes to the consolidated financial statements:

◦Note 8, Secured and Unsecured Debt of the Company;

◦Note 9, Secured and Unsecured Debt of the Operating Partnership;

◦Note 11, Noncontrolling Interests on the Company’s Consolidated Financial Statements;

◦Note 12, Noncontrolling Interests on the Operating Partnership’s Consolidated Financial Statements;

◦Note 13, Stockholders’ Equity of the Company;

◦Note 14, Partners’ Capital of the Operating Partnership;

◦Note 20, Net Income Available to Common Stockholders Per Share of the Company;

◦Note 22, Supplemental Cash Flow Information of the Company;

◦Note 23, Supplemental Cash Flow Information of the Operating Partnership;

◦Note 25, Quarterly Financial Information of the Company (Unaudited); and

◦Note 26, Quarterly Financial Information of the Operating Partnership (Unaudited).

This report also includes separate sections under Item 9A. Controls and Procedures and separate Exhibit 31 and Exhibit 32 certifications for the Company and the Operating Partnership to establish that the Chief Executive Officer and the Chief Financial Officer of each entity have made the requisite certifications and that the Company and Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and 18 U.S.C. §1350.

PART I

This document contains certain “forward-looking” statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including, among other things, statements or information concerning our plans, objectives, capital resources, portfolio performance, results of operations, projected future occupancy and rental rates, lease expirations, debt maturities, potential investments, strategies such as capital recycling, development and redevelopment activity, projected construction costs, projected construction commencement and completion dates, projected square footage of space that could be constructed on undeveloped land that we own, projected rentable square footage of or number of units in properties under construction or in the development pipeline, anticipated proceeds from capital recycling activity or other dispositions and anticipated dates of those activities or dispositions, projected increases in the value of properties, dispositions, future executive incentive compensation, pending, potential or proposed acquisitions, plans to grow our net operating income and funds from operations, our ability to re-lease properties at or above current market rates, anticipated market conditions, demographics and other forward-looking financial data, as well as the discussion in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations -Factors That May Influence Future Results of Operations.” Forward-looking statements are based on our current expectations, beliefs and assumptions, and are not guarantees of future performance. Forward-looking statements are inherently subject to uncertainties, risks, changes in circumstances, trends and factors that are difficult to predict, many of which are outside of our control. Accordingly, actual performance, results and events may vary materially from those indicated or implied in the forward-looking statements, and you should not rely on the forward-looking statements as predictions of future performance, results or events. All forward-looking statements are based on information that was available and speak only as of the dates on which they were made. We assume no obligation to update any forward-looking statement that becomes untrue because of subsequent events, new information or otherwise, except to the extent we are required to do so in connection with our ongoing requirements under federal securities laws.

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

ITEM 1. BUSINESS

The Company

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

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


	Number of Buildings	Rentable Square Feet	Number of Tenants	Percentage Occupied (1)		Percentage Leased
Stabilized Office Properties (2)	117	14,620,166	447	91.2	%	94.3	%

________________________

(1)Represents physical and economic occupancy.

(2)Includes stabilized life science and retail space.


	Number of Properties	Number of Units	2020 Average Occupancy
Stabilized Residential Properties	2	808	72.0	%

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

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


	Number of Properties/Projects	Estimated Rentable Square Feet (1)
In-process development projects - tenant improvement	3	1,080,000
In-process development projects - under construction (2)	3	856,000

________________________

(1)Estimated rentable square feet upon completion.

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

Our stabilized portfolio also excludes our future development pipeline, which as of December 31, 2020, was comprised of five future development sites, representing approximately 61 gross acres of undeveloped land.

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

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

Business and Growth Strategies

Growth Strategies. We believe that a number of factors and strategies will enable us to continue to achieve our objectives of long-term sustainable growth in Net Operating Income (defined below) and FFO (defined below) as well as maximization of long-term stockholder value. These factors and strategies include:

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

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

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

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

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

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

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

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

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

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

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

•structuring leases to maximize returns;

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

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

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

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

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

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

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

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

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

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

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

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

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

We may engage in the additional development or redevelopment of office, life science and mixed-use properties when market conditions support a favorable risk-adjusted return on such development or redevelopment. We expect

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

Acquisition Strategies. We believe we are well positioned to acquire opportunistic properties and development and redevelopment opportunities as the result of our extensive experience, strong financial position and ability to access capital. We continue to focus on growth opportunities in West Coast markets populated by knowledge and creative based tenants in a variety of industries, including technology, media, healthcare, life sciences, entertainment and professional services. Against the backdrop of market volatility, we expect to manage a strong balance sheet, execute on our development program and selectively evaluate opportunities that add immediate Net Operating Income to our portfolio or play a strategic role in our future growth and that:

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

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

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

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

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

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

•maintaining a staggered debt maturity schedule in which the maturity dates of our debt are spread over several years to limit risk exposure at any particular point in the capital and credit market cycles;

•completing financing in advance of the need for capital;

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

•maintaining our credit ratings.

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

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

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

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

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

Percentage is based total energy consumption during the applicable year.

(5)Data reported on a like-for-like comparison excludes assets that have been acquired or disposed over the past twenty-four months as of the end of the applicable year.

(6)Eligible portfolio represents our office and residential properties that have had 50% or greater occupancy for 12 consecutive months at any point during the applicable year. Percentage is based on rentable square footage of our eligible portfolio that has obtained an energy rating and is certified to ENERGY STAR® as of the end of the applicable year.

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

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

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

(10)Scope 1 emissions represent those produced by consuming onsite natural gas procured by the Company.

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

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

We build our current development projects to Leadership in Energy and Environmental Design (“LEED”) specifications. All of our office development projects are designed to achieve LEED certification, either LEED Platinum or Gold.

We are actively pursuing LEED certification for approximately 856,000 square feet of office and life science space under construction. In addition, an analysis of energy and water performance is included in our standard due

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

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

Significant Tenants

As of December 31, 2020, our 15 largest tenants in terms of annualized base rental revenues represented approximately 49.1% of our total annualized base rental revenues, defined as annualized monthly contractual rents from existing tenants as of December 31, 2020. Annualized base rental revenue includes the impact of straight-lining rent escalations and the amortization of free rent periods and excludes the impact of the following: amortization of deferred revenue related tenant-funded tenant improvements, amortization of above/below market rents, amortization for lease incentives due under existing leases and expense reimbursement revenue.

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

Competition

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

Segment and Geographic Financial Information

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

Human Capital Resources

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

Our human capital development goals and initiatives are focused on enhancing employee growth, satisfaction and wellness while maintaining a diverse and thriving culture. Several of our human capital development initiatives include the following:

Diversity. We are committed to cultivating a diverse culture of inclusion that makes a positive difference in our employees’ lives and have developed targeted training to improve workplace diversity, equity and inclusion. As of December 31, 2020, our employees were:

•59% female; 41% male

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

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

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

Strong Communities and Healthy Planet. We are deeply aware that our buildings are part of the larger community and that we thrive when the communities around us thrive. We are proud to make these communities better places to live and work through our volunteerism and philanthropy initiatives.

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

Our compensation program is designed to, among other things, attract, retain and incentivize talented and experienced individuals in the highly competitive West Coast employment and commercial real estate markets. We use a mix of competitive salaries and other benefits to attract and retain these individuals.

Environmental Regulations and Potential Liabilities

Government Regulations Relating to the Environment. Many laws and governmental regulations relating to the environment are applicable to our properties, and changes in these laws and regulations, or their interpretation by agencies and the courts, occur frequently and may adversely affect us.

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

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

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

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

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

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

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

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

SUMMARY RISK FACTORS

The following section sets forth a summary of material factors that may adversely affect our business and operations. For a more extensive discussion of these factors, see “1A. Risk Factors” contained in this report.

•The ongoing COVID-19 pandemic, and restrictions intended to prevent its spread, could adversely impact our business, financial condition, results of operations, cash flows, liquidity and ability to satisfy our debt service obligations and to pay dividends and distributions to security holders.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

•We own certain properties subject to ground leases and other restrictive agreements that limit our uses of the properties, restrict our ability to sell or otherwise transfer the properties and expose us to the loss of the properties if such agreements are breached by us, terminated or not renewed.

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

•We face risks associated with security breaches through cyber attacks, cyber intrusions or otherwise, as well as other significant disruptions of our information technology (IT) networks and related systems.

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

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

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

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

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

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

ITEM 1A. RISK FACTORS

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

Risks Related to our Business and Operations

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

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

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

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

The ongoing COVID-19 pandemic, and restrictions intended to prevent its spread, could have significant adverse impacts on our business, financial condition, results of operations, cash flows, liquidity and ability to satisfy our debt service obligations and to pay dividends and distributions to security holders in a variety of ways that are difficult to predict. Such adverse impacts could depend on, among other factors:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

•inability to collect rent from tenants;

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

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

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

•costs of complying with changes in governmental regulations;

•the relative illiquidity of real estate investments;

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

•changing submarket demographics;

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

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

•property damage resulting from seismic activity or other natural disasters.

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

Our financial condition, results of operations, ability to borrow funds and cash flows would be adversely affected if any of our significant tenants fails to renew its lease(s), renew its lease(s) on terms less favorable to us, or becomes bankrupt or insolvent or otherwise unable to satisfy its lease obligations.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

There are significant risks associated with property acquisition, development and redevelopment. We may be unable to successfully complete and operate acquired, developed and redeveloped properties, and it is possible that:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Owning these securities may not entitle us to control the ownership, operation and management of the underlying real estate. In addition, we may have no control over the distributions with respect to these securities, which could adversely affect our ability to pay dividends and distributions to our security holders.

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

•direct obligations issued by the U.S. Treasury;

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

•taxable municipal securities;

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

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

•repurchase agreements collateralized by corporate and asset-backed obligations;

•both registered and unregistered money market funds; and

•other highly rated short-term securities.

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

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

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

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

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

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

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

•result in the theft of funds;

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

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

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

•damage our reputation among our tenants and investors.

These events could have an adverse impact on our financial condition, results of operations, cash flows, the quoted trading price of our securities, and our ability to satisfy our debt service obligations and to pay dividends and distributions to our security holders.

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

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

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

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

Risks Related to Our Indebtedness

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

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

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

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

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

We may need to refinance all or a portion of our indebtedness on or before maturity. Our ability to refinance our indebtedness or obtain additional financing will depend on, among other things:

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

•restrictions in the agreements governing our indebtedness.

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

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

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

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

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

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

Risks Related to Our Organizational Structure

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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


	Number of Buildings	Rentable Square Feet	Number of Tenants	Percentage Occupied (1)		Percentage Leased
Stabilized Office Properties (2)	117	14,620,166	447	91.2	%	94.3	%

_______________________

(1)Represents physical and economic occupancy.

(2)Includes stabilized life science and retail space.


	Number of Properties	Number of Units	2020 Average Occupancy
Stabilized Residential Properties	2	808	72.0	%

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

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


	Number of Properties/Projects	Estimated Rentable Square Feet (1)
In-process development projects - tenant improvement	3	1,080,000
In-process development projects - under construction (2)	3	856,000

________________________

(1)Estimated rentable square feet upon completion.

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

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

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

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

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

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

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

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

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

(4) FFO includes amortization of deferred revenue related to tenant-funded tenant improvements of $22.5 million, $19.2 million, $18.4 million, $16.8 million and $13.2 million for the years ended December 31, 2020, 2019, 2018, 2017 and 2016, respectively.

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

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

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

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

Forward-Looking Statements

Statements contained in this “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” that are not historical facts may be forward-looking statements. Forward-looking statements include, among other things, statements or information concerning our plans, objectives, capital resources, portfolio performance, results of operations, projected future occupancy and rental rates, lease expirations, debt maturities, potential investments, strategies such as capital recycling, development and redevelopment activity, projected construction costs, projected construction commencement and completion dates, projected square footage of space that could be constructed on undeveloped land that we own, projected rentable square footage of or number of units in properties under construction or in the development pipeline, anticipated proceeds from capital recycling activity or other dispositions and anticipated dates of those activities or dispositions, projected increases in the value of properties, dispositions, future executive incentive compensation, pending, potential or proposed acquisitions, plans to grow our Net Operating Income and FFO, our ability to re-lease properties at or above current market rates, anticipated market conditions and demographics and other forward-looking financial data, as well as the discussion in “—Factors That May Influence Future Results of Operations,” “—Liquidity and Capital Resource of the Company,” and “—Liquidity and Capital Resources of the Operating Partnership.” Forward-looking statements can be identified by the use of words such as “believes,” “expects,” “projects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “pro forma,” “estimates” or “anticipates” and the negative of these words and phrases and similar expressions that do not relate to historical matters. Forward-looking statements are based on our current expectations, beliefs and assumptions, and are not guarantees of future performance. Forward-looking statements are inherently subject to uncertainties, risks, changes in circumstances, trends and factors that are difficult to predict, many of which are outside of our control. Accordingly, actual performance, results and events may vary materially from those indicated or implied in the forward-looking statements, and you should not rely on the forward-looking statements as predictions of future performance, results or events. Numerous factors could cause actual future performance, results and events to differ materially from those indicated in the forward-looking statements, including, among others:

•global market and general economic conditions and their effect on our liquidity and financial conditions and those of our tenants;

•adverse economic or real estate conditions generally, and specifically, in the States of California and Washington;

•risks associated with our investment in real estate assets, which are illiquid, and with trends in the real estate industry;

•defaults on or non-renewal of leases by tenants;

•any significant downturn in tenants’ businesses;

•our ability to re-lease property at or above current market rates;

•costs to comply with government regulations, including environmental remediations;

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

•increases in interest rates and our ability to manage interest rate exposure;

•the availability of financing on attractive terms or at all, which may adversely impact our future interest expense and our ability to pursue development, redevelopment and acquisition opportunities and refinance existing debt;

•a decline in real estate asset valuations, which may limit our ability to dispose of assets at attractive prices or obtain or maintain debt financing, and which may result in write-offs or impairment charges;

•significant competition, which may decrease the occupancy and rental rates of properties;

•potential losses that may not be covered by insurance;

•the ability to successfully complete acquisitions and dispositions on announced terms;

•the ability to successfully operate acquired, developed and redeveloped properties;

•the ability to successfully complete development and redevelopment projects on schedule and within budgeted amounts;

•delays or refusals in obtaining all necessary zoning, land use and other required entitlements, governmental permits and authorizations for our development and redevelopment properties;

•increases in anticipated capital expenditures, tenant improvement and/or leasing costs;

•defaults on leases for land on which some of our properties are located;

•adverse changes to, or enactment or implementations of, tax laws or other applicable laws, regulations or legislation, as well as business and consumer reactions to such changes;

•risks associated with joint venture investments, including our lack of sole decision-making authority, our reliance on co-venturers’ financial condition and disputes between us and our co-venturers;

•environmental uncertainties and risks related to natural disasters;

•our ability to maintain our status as a REIT; and

•uncertainties regarding the impact of the COVID-19 pandemic, and restrictions intended to prevent its spread, on our business and the economy generally.

The factors included in this report are not exhaustive and additional factors could adversely affect our business and financial performance. For a discussion of additional factors that could materially adversely affect the Company’s and the Operating Partnership’s business and financial performance, see the discussion below as well as “Item 1A. Risk Factors,” and in our other filings with the SEC. All forward-looking statements are based on information that was available and speak only as of the dates on which they were made. We assume no obligation to update any forward-looking statement that becomes untrue because of subsequent events, new information or otherwise, except to the extent we are required to do so in connection with our ongoing requirements under federal securities laws.

Company Overview

We are a self-administered REIT active in premier office and mixed-use submarkets along the West Coast. We own, develop, acquire and manage real estate assets, consisting primarily of Class A properties in the coastal regions of Greater Los Angeles, San Diego County, the San Francisco Bay Area and Greater Seattle, which we believe have strategic advantages and strong barriers to entry. We own our interests in all of our real properties through the Operating Partnership and generally conduct substantially all of our operations through the Operating Partnership. We owned an approximate 99.0% and 98.1% general partnership interest in the Operating Partnership as of December 31, 2020 and 2019, respectively. All of our properties are held in fee except for the fourteen office buildings that are held subject to long-term ground leases for the land (see Note 18 “Commitments and Contingencies” to our consolidated financial statements included in this report for additional information regarding our ground lease obligations).

2020 Operating and Development Highlights

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

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

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

Leasing. During 2020, we executed new and renewal leases totaling 0.7 million square feet within our stabilized portfolio with an increase in GAAP rents of 36.5% and an increase in cash rents of 18.4%. Our stabilized office portfolio was 91.2% occupied and 94.3% leased as of December 31, 2020.

2020 Financing Highlights

In 2020, we raised approximately $775.0 million in new debt at a weighted average interest rate of 3.30%, settled all 2019 forward equity sale agreements by issuing 3,147,110 shares of common stock for net proceeds of $247.3 million and entered into and settled forward equity sale agreements in connection with an offering of 5,750,000 shares of common stock for net proceeds of $474.9 million. Refer to our 2020 Financing Highlights in “—Liquidity and Capital Resources of the Operating Partnership” for a list of financing transactions completed in 2020 and Notes 9 and 13, “Secured and Unsecured Debt of the Operating Partnership” and “Stockholders’ Equity of the Company,” respectively, to our consolidated financial statements included in this report for additional information regarding our debt and capital market activity.

COVID-19 Response

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

Since March 2020, we have been highly focused on planning for the health and safety of our tenants and employees and preparing our buildings in accordance with the policies, protocols and applicable legal requirements in our regions. We engaged a hygienist to assist us in designing new standard operating procedures for our buildings that include, but are not limited to, air filtration, water quality, janitorial products and procedures, social separation and screening during building access and elevator use, the use of personal protective equipment, signage, and management of construction activities. Our buildings have remained open to tenants and we have begun to see certain tenants returning to the workplace where local ordinances and restrictions allow. We have been in communication with tenants regarding return to work protocols and safety measures, which meet or exceed best practices from state and local guidelines.

We have implemented a rent relief program for the majority of our retail tenants whereby we deferred rent since April 2020 in exchange for an extension of their current lease term for an equivalent number of months at future rental rates. We expect that we will continue to offer rent relief to the majority of our retail tenants, given that most cannot resume full operations in certain of our markets where strong state and local government restrictions remain or were put back into effect, although the form of relief offered may vary in the future. We did not create such a program for our office tenants. We evaluate office rent relief requests on a specific case by case basis and only consider those which have a justifiable financial basis. Our top 15 tenants represent 49.1% of our total annualized base rental revenues and as of December 31, 2020, we had collected 100% of the rent due from our top 15 tenants since the beginning of the COVID-19 pandemic. For residential tenants, deferrals of gross rent billings have been extended in accordance with the applicable local orders, which often require repayment within 12 months if such local ordinances are not extended.

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

The following table sets forth information regarding the percent of contractual base rent and common area maintenance (“CAM”) billings (“gross rent billings”) billed, collected, forgiven, and deferred for the three months ended December 31, 2020:

(2)Cash collections on billings for the year ended December 31, 2020 as a percentage of gross rent billings.

(5)Amounts permanently forgiven as a percentage of gross rent billings.

(6)Collections of amounts deferred under repayment plans (as described above) and through lease term extensions as a percentage of gross rent billings.

(7)Remaining amounts deferred under repayment plans and through lease term extensions as a percentage of gross rent billings.

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

As of February 1, 2021, across all property types, we had collected approximately 95% of our January 2021 gross rent billings, including 100% from all of our top 15 tenants. Excluding rent relief provided to certain tenants, across all property types, we collected 96% of our January 2021 gross rent billings. We are continuing to monitor the potential impact of the COVID-19 pandemic, and restrictions intended to prevent its spread, on occupancy, rental rates and rent collections. Although we are and will continue to be actively engaged in rent collection efforts related to uncollected rent for such period, as well as working with certain tenants who have requested rent deferrals, we can provide no assurance that such efforts or our efforts in future periods will be successful, particularly in the event that the COVID-19 pandemic, and restrictions intended to prevent its spread, continue for a prolonged period. Refer to “Part I, Item IA. Risk Factors” included in this report for additional information about the potential impact of the COVID-19 pandemic, and restrictions intended to prevent its spread, on our business, financial condition, results of operations, cash flows, liquidity and ability to satisfy our debt service obligations and to pay dividends and distributions to security holders.

Critical Accounting Policies

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

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

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

Revenue Recognition

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

Base Rent

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

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

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

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

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

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

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

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

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

For residential properties, we commence revenue recognition upon lease commencement. Residential rental revenue is recognized on a straight-line basis over the term of the related lease, net of any concessions.

Additional Rent - Reimbursements from Tenants

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

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

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

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

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

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

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

Uncollectible Lease Receivables and Allowances for Tenant and Deferred Rent Receivables

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

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

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

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

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

Acquisitions

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

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

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

The determination of the fair value of any debt assumed in connection with a property acquisition is estimated by discounting the future cash flows using interest rates available for the issuance of debt with similar terms and remaining maturities.

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

Transaction costs associated with our acquisitions, including costs incurred during negotiation, are capitalized as part of the purchase price of the acquisition. During the years ended December 31, 2020, 2019 and 2018, we capitalized $0.3 million, $1.6 million, and $3.8 million, respectively, of acquisition costs.

Evaluation of Asset Impairment

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

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

•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;

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

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

•evidence of material physical damage to the property; and

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

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

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

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

Cost Capitalization and Depreciation

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

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

Determining whether expenditures meet the criteria for capitalization and the assignment of depreciable lives requires management to exercise significant judgment. Expenditures that meet one or more of the following criteria generally qualify for capitalization:

•provide benefit in future periods;

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

•increase the quality of the asset beyond our original estimates.

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

Share-Based Incentive Compensation Accounting

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

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

Factors That May Influence Future Results of Operations

Development Program

We believe that a portion of our long-term future growth will continue to come from the completion of our in-process development projects and, subject to market conditions, executing on our future development pipeline, including expanding entitlements. Over the past several years, we increased our focus on development opportunities and expanded our future development pipeline through targeted acquisitions of development opportunities on the West Coast.

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

The global impact of the COVID-19 pandemic continues to evolve rapidly and, as cases of the illness caused by the virus have continued to be identified in additional countries, many countries, including the United States, have reacted by instituting quarantines and restrictions on travel. In addition, both states where we own properties and/or have development projects (i.e., California and Washington), have reacted to the COVID-19 pandemic by instituting quarantines, restrictions on travel, “shelter in place” rules, density limitations, social distancing measures, restrictions on types of business that may continue to operate and/or restrictions on types of construction projects that may continue, although, in certain cases, exceptions are available for essential retail, research and laboratory activities, essential building services, such as cleaning and maintenance, and certain essential construction projects. Our development portfolio was largely unaffected during the year ended December 31, 2020; however, the COVID-19 pandemic, and restrictions intended to prevent its spread, may cause delays or increase costs associated with building materials or construction services necessary for construction which could adversely impact our ability to continue or complete construction as planned, on budget or at all for our development projects, and may delay the start of construction on our future development pipeline projects. Refer to “Part I , Item IA. Risk Factors” included in this report for additional information about the potential impact of the COVID-19 pandemic, and restrictions intended to prevent its spread, on our business, financial condition, results of operations, cash flows, liquidity and ability to satisfy our debt service obligations and to pay dividends and distributions to security holders.

Stabilized Development Projects

During the year ended December 31, 2020, we added the following projects to our stabilized portfolio:

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

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

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

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

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

In-Process Development Projects - Tenant Improvement

As of December 31, 2020, the following projects were in the tenant improvement phase:

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

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

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

In-Process Development Projects - Under Construction

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

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

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

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

Future Development Pipeline

As of December 31, 2020, our future development pipeline included five future projects located in Greater Seattle, the San Francisco Bay Area and San Diego County with an aggregate cost basis of approximately $1.1 billion, at which we believe we could develop more than 6.0 million rentable square feet for a total estimated investment of approximately $5.0 billion to $7.0 billion, depending on successfully obtaining entitlements and market conditions.

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

Fluctuations in our development activities could cause fluctuations in the average development asset balances qualifying for interest and other carrying cost and internal cost capitalization in future periods. During the years ended December 31, 2020 and 2019, we capitalized interest on in-process development projects and future development pipeline projects with an average aggregate cost basis of approximately $2.0 billion, as it was determined these projects qualified for interest and other carrying cost capitalization under GAAP. In the event of an extended cessation of development activities, such projects may potentially no longer qualify for capitalization of interest or other carrying costs. However, a cessation of development activities caused by events outside of our control, such as those as a result of government restrictions aimed at stopping the spread of COVID-19, would not impact our ability to capitalize interest and other carrying costs. For the years ended December 31, 2020 and 2019, we capitalized $79.6 million and $81.2 million, respectively, of interest to our qualifying development projects. For the years ended December 31, 2020 and 2019, we capitalized $21.8 million and $25.6 million, respectively, of internal costs to our qualifying redevelopment and development projects.

Capital Recycling Program

We continuously evaluate opportunities for the potential disposition of non-core properties and undeveloped land in our portfolio or the formation of strategic ventures with the intent of recycling the proceeds generated into capital used to fund new operating and development acquisitions, to finance development and redevelopment expenditures, to repay long-term debt and for other general corporate purposes. As part of this strategy, we attempt to enter into Section 1031 Exchanges and other tax deferred transaction structures, when possible, to defer some or all of the taxable gains on the sales, if any, for federal and state income tax purposes. See the “Liquidity and Capital Resources of the Operating Partnership – Liquidity Sources” section for further discussion of our capital recycling activities.

In connection with our capital recycling strategy, during 2020, we completed the sale of one office property to an unaffiliated third party for total gross sales proceeds of $75.9 million. During 2019, we completed the sale of two office properties to unaffiliated third parties for total gross sales proceeds of $133.8 million.

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

Acquisitions

As part of our growth strategy, which is highly dependent on market conditions and business cycles, among other factors, we continue to evaluate strategic opportunities and remain a disciplined buyer of development and redevelopment opportunities as well as value-add operating properties. We focus on growth opportunities in West Coast markets populated by knowledge and creative based tenants in a variety of industries, including technology, media, healthcare, life sciences, entertainment and professional services. Against the backdrop of market volatility, we expect to manage a strong balance sheet, execute on our development program and selectively evaluate opportunities that either add immediate Net Operating Income to our portfolio or play a strategic role in our future growth.

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

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

Incentive Compensation

Our Executive Compensation Committee determines compensation, including cash bonuses and equity incentives, for our executive officers, as defined in Rule 16 under the Exchange Act. For 2020, the annual cash bonus program was structured to allow the Executive Compensation Committee to evaluate a variety of key quantitative and qualitative metrics at the end of the year and make a determination based on the Company’s and management’s overall performance. Our Executive Compensation Committee also grants equity incentive awards from time to time that include performance-based and/or market-measure based vesting requirements and time-based vesting requirements. As a result, accrued incentive compensation and compensation expense for future awards may be affected by our operating and development performance, financial results, stock price, performance against applicable performance-based vesting goals, market conditions, liquidity measures, and other factors. Consequently, we cannot predict the amounts that will be recorded in future periods related to such incentive compensation.

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

awards could be affected by our operating and development performance, financial results, stock price, performance against applicable performance-based vesting goals, market conditions and other factors. For additional information regarding our equity incentive awards, see Note 15 “Share-Based and Other Compensation” to our consolidated financial statements included in this report.

Information on Leases Commenced and Executed

Leasing Activity and Changes in Rental Rates. The amount of net rental income generated by our properties depends principally on our ability to maintain the occupancy rates of currently leased space and to lease currently available space, newly developed or redeveloped properties, newly acquired properties with vacant space, and space available from unscheduled lease terminations. The amount of rental income we generate also depends on our ability to maintain or increase rental rates in our submarkets. Negative trends in one or more of these factors could adversely affect our rental income in future periods. The following tables set forth certain information regarding leasing activity for our stabilized portfolio during the year ended December 31, 2020.

(1)Includes 100% of consolidated property partnerships.

(2)First generation leasing includes space where we have made capital expenditures that result in additional revenue generated when the space is re-leased. Second generation leasing includes space where we have made capital expenditures to maintain the current market revenue stream.

(3)Represents leasing activity for leases that commenced or were signed during the period, including first and second generation space, net of month-to-month leases. Excludes leasing on new construction.

(4)Calculated as the percentage of space either renewed or expanded into by existing tenants or subtenants at lease expiration.

(5)Tenant improvements and leasing commissions per square foot exclude tenant-funded tenant improvements.

(6)Calculated as the change between GAAP rents for new/renewed leases and the expiring GAAP rents for the same space. Excludes leases for which the space was vacant longer than one year or vacant when the property was acquired.

(7)Excludes commenced and executed leases of approximately 615,639 and 61,445 rentable square feet, respectively, for the year ended December 31, 2020, for which the space was vacant longer than one year or being leased for the first time. Space vacant for more than one year is excluded from our change in rents calculations to provide a more meaningful market comparison.

(8)Calculated as the change between stated rents for new/renewed leases and the expiring stated rents for the same space. Excludes leases for which the space was vacant longer than one year or vacant when the property was acquired.

(9)For the year ended December 31, 2020, 4 new leases totaling 105,103 rentable square feet were signed but not commenced as of December 31, 2020.

Our rental rates and occupancy are impacted by general economic conditions, including the pace of regional economic growth, access to capital, and potentially the current COVID-19 pandemic and restrictions intended to prevent its spread. Therefore, we cannot give any assurance that leases will be renewed or that available space will be re-leased at rental rates equal to or above the current market rates. In addition, due to the uncertainty of current market rents as a result of the COVID-19 pandemic and the impact it has had on recent transaction volume in our markets, we are currently unable to provide meaningful information on the weighted average cash rental rates for our total stabilized portfolio compared to current market rates at December 31, 2020. In addition, it is possible that

the COVID-19 pandemic may have an adverse impact on our ability to renew leases or re-lease available space in our properties on favorable terms or at all in the future, including as a result of a deterioration in the economic and market conditions due to restrictions intended to prevent the spread of COVID-19. These restrictions and social distancing guidelines limited our ability to physically show space to prospective tenants and impeded initiating new and progressing active leasing transactions. While we do not believe that our development leasing and ability to renew leases scheduled to expire has been significantly impacted by the COVID-19 pandemic, we do believe that the impact of the restrictions and social distancing guidelines and the economic uncertainty caused by the COVID-19 pandemic has impacted the timing and volume of leasing and may continue to do so in the future. Additionally, decreased demand, increased competition (including sublease space available from our tenants) and other negative trends or unforeseeable events that impair our ability to timely renew or re-lease space could have further negative effects on our future financial condition, results of operations, and cash flows.

Scheduled Lease Expirations. The following tables set forth certain information regarding our lease expirations for our stabilized portfolio for the next five years and by region for the next two years.

(1) For leases that have been renewed early with existing tenants, the expiration date and annualized base rent information presented takes into consideration the renewed lease terms. Excludes leases not commenced as of December 31, 2020, space leased under month-to-month leases, storage leases, vacant space and future lease renewal options not executed as of December 31, 2020.

(2) Annualized base rent includes the impact of straight-lining rent escalations and the amortization of free rent periods and excludes the impact of the following: amortization of deferred revenue related tenant-funded tenant improvements, amortization of above/below market rents, amortization for lease incentives due under existing leases, and expense reimbursement revenue. Additionally, the underlying leases contain various expense structures including full service gross, modified gross and triple net. Percentages represent percentage of total portfolio annualized contractual base rental revenue. For additional information on tenant improvement and leasing commission costs incurred by the Company for the current reporting period, please see further discussion under the caption “Information on Leases Commenced and Executed.”

(3) Includes 100% of annualized base rent of consolidated property partnerships.

(4) Adjusting for leases executed as of December 31, 2020 but not yet commenced, the 2021 and 2022 expirations would be reduced by 121,554 and 38,806 square feet, respectively.

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

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

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

Stabilized Portfolio Information

As of December 31, 2020, our stabilized portfolio was comprised of 117 office properties encompassing an aggregate of approximately 14.6 million rentable square feet and 808 residential units. Our stabilized portfolio includes all of our properties with the exception of development and redevelopment properties currently committed for construction, under construction or in the tenant improvement phase, undeveloped land and real estate assets held for sale. We define redevelopment properties as those properties for which we expect to spend significant development and construction costs on the existing or acquired buildings pursuant to a formal plan, the intended result of which is a higher economic return on the property. We define properties in the tenant improvement phase as office and life science properties that we are developing or redeveloping where the project has reached cold shell condition and is ready for tenant improvements, which may require additional major base building construction before being placed in service. Projects in the tenant improvement phase are added to our stabilized portfolio once the project reaches the earlier of 95% occupancy or one year from the date of the cessation of major base building construction activities. Costs capitalized to construction in progress for development and redevelopment properties are transferred to land and improvements, buildings and improvements, and deferred leasing costs on our consolidated balance sheets as the historical cost of the property as the projects or phases of projects are placed in service.

We did not have any redevelopment or held for sale properties at December 31, 2020. Our stabilized portfolio also excludes our future development pipeline, which as of December 31, 2020 was comprised of five potential development sites, representing approximately 61 gross acres of undeveloped land on which we believe we have the potential to develop more than 6.0 million rentable square feet, depending upon economic conditions.

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


	Number of Properties/Projects	Estimated Rentable Square Feet (1)
In-process development projects - tenant improvement	3	1,080,000
In-process development projects - under construction (2)	3	856,000

________________________

(1)Estimated rentable square feet upon completion.

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

Results of Operations

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

Net Operating Income

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

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

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

•Same Store Properties – includes the consolidated results of all of the office properties that were owned and included in our stabilized portfolio for two comparable reporting periods, i.e., owned and included in our stabilized portfolio as of January 1, 2019 and still owned and included in the stabilized portfolio as of December 31, 2020, including our residential tower in Hollywood, California;

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

◦One office development project that was added to the stabilized portfolio in the second quarter of 2019;

◦One office development project that was added to the stabilized portfolio in the first quarter of 2020;

◦One retail development project that was added to the stabilized portfolio in the first quarter of 2020;

◦One office development project that was added to the stabilized portfolio in the fourth quarter of 2020; and

◦608 residential units at our One Paseo mixed-use project in Del Mar, California that were added to the stabilized portfolio in the third quarter of 2020.

•Acquisition Properties – includes the results, from the dates of acquisition through the periods presented, for the 19-building creative office campus we acquired during 2019; and

•Disposition Properties – includes the results of the one property disposed of in the second quarter of 2019, the one property disposed of in the fourth quarter of 2019, and the one property disposed of in the fourth quarter of 2020.

The following table sets forth certain information regarding the property groups within our stabilized office portfolio as of December 31, 2020.

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

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

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

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

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

◦$8.1 million decrease due to lower parking income, of which $4.1 million relates to a reduction in the number of monthly parking spaces rented as a result of COVID-19 stay-at-home orders and $4.0 million relates to lower transient and special event parking income at a number of properties in the San Francisco Bay Area, Greater Seattle and Greater Los Angeles regions. We expect daily, special event and transient parking to be impacted while restrictions intended to prevent the spread of COVID-19 are in effect; and

◦$3.2 million decrease due to lower reimbursable operating expenses;

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

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

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

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

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

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

•An increase of $58.5 million attributable to the Development Properties; and

•An increase of $5.6 million attributable to the Acquisition Properties; partially offset by

•A decrease of $5.5 million attributable to the Disposition Properties.

Other Expenses and Income

General and Administrative Expenses

General and administrative expenses increased by approximately $11.1 million, or 12.6%, for the year ended December 31, 2020 compared to the year ended December 31, 2019 primarily due to the following:

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

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

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

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

Leasing Costs

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

Depreciation and Amortization

Depreciation and amortization increased by approximately $26.2 million, or 9.6%, for the year ended December 31, 2020 compared to the year ended December 31, 2019, primarily due to the following:

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

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

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

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

Interest Expense

The following table sets forth our gross interest expense, including debt discounts/premiums and deferred financing cost amortization and capitalized interest, including capitalized debt discounts/premiums and deferred financing cost amortization for the years ended December 31, 2020 and 2019.


	Year Ended December 31,				Dollar Change		Percentage Change
	2020		2019
	($ in thousands)
Gross interest expense	$	150,325	$	129,778	$	20,547	15.8	%
Capitalized interest and deferred financing costs	(79,553)		(81,241)		1,688		(2.1)
Interest expense	$	70,772	$	48,537	$	22,235	45.8	%

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

Capitalized interest and deferred financing costs decreased $1.7 million, or 2.1%, for the year ended December 31, 2020 compared to the year ended December 31, 2019, primarily attributable to a decrease in the weighted average interest rate during 2020. During both years ended December 31, 2020 and 2019, we capitalized interest on in-process development projects and future development pipeline projects with an average aggregate cost basis of approximately $2.0 billion. In the event of an extended cessation of development activities to get any of these projects ready for its intended use, such projects could potentially no longer qualify for capitalization of interest or other carrying costs. However, a cessation of development activities caused by events outside of our control, such as those as a result of government restrictions aimed at stopping the spread of COVID-19, would not impact our ability to capitalize interest and other carrying costs. Refer to “Part I, Item IA. Risk Factors” included in this report for additional information about the potential impact of the COVID-19 pandemic, and restrictions intended to prevents its spread, on our business, financial condition, results of operations, cash flows, liquidity and ability to satisfy our debt service obligations and to pay dividends and distributions to security holders.

Net income attributable to noncontrolling interests in consolidated property partnerships

Net income attributable to noncontrolling interests in consolidated property partnerships increased $1.3 million, or 8.1%, for the year ended December 31, 2020 compared to the year ended December 31, 2019 primarily due to a new lease at a higher rate at one property held in a property partnership in 2020 partially offset by charges related to the creditworthiness of certain tenants. The amounts reported for the years ended December 31, 2020 and 2019 are comprised of the noncontrolling interest’s share of net income for 100 First Member, LLC (“100 First LLC”) and 303 Second Street Member, LLC (“303 Second LLC”) and the noncontrolling interest’s share of net income for Redwood LLC. See Note 11 “Noncontrolling Interests on the Company’s Consolidated Financial Statements” to our consolidated financial statements included in this report for additional information.

Refer to “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations –Results of Operations” in our Form 10-K for the year ended December 31, 2019 for a discussion of the year ended December 31, 2019 compared to the year ended December 31, 2018.

Liquidity and Capital Resources of the Company

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

The Company’s business is operated primarily through the Operating Partnership. Distributions from the Operating Partnership are the Company’s primary source of capital. The Company believes the Operating Partnership’s sources of working capital, specifically its cash flow from operations and borrowings available under its unsecured revolving credit facility and funds from its capital recycling program, including strategic ventures, are adequate for it to make its distribution payments to the Company and, in turn, for the Company to make its dividend payments to its common stockholders for the next twelve months. Cash flows from operating activities generated by the Operating Partnership for the year ended December 31, 2020 were sufficient to cover the Company’s payment of cash dividends to its stockholders. However, there can be no assurance that the Operating Partnership’s sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including its ability to make distributions to the Company. The unavailability of capital could adversely affect the Operating Partnership’s ability to make distributions to the Company, which would in turn, adversely affect the Company’s ability to pay cash dividends to its stockholders.

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

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

COVID-19 Liquidity Highlights

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

Distribution Requirements

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

The Company intends to continue to make, but has not committed to make, regular quarterly cash distributions to common stockholders, and through the Operating Partnership, common unitholders from the Operating Partnership’s cash flow from operating activities. All such distributions are at the discretion of the Board of Directors. In 2020, the Company’s distributions exceeded 100% of its taxable income, resulting in a return of capital to its stockholders. As the Company intends to maintain distributions at a level sufficient to meet the REIT distribution requirements and minimize its obligation to pay income and excise taxes, it will continue to evaluate whether the current levels of distribution are appropriate to do so for 2021. In addition, in the event the Company is unable to identify and complete the acquisition of suitable replacement properties to effect Section 1031 Exchanges or is unable to successfully complete Section 1031 Exchanges to defer some or all of the taxable gains related to property dispositions as a result of the COVID-19 pandemic or any other reason, the Company may elect to distribute a special dividend to its common stockholders and common unitholders in order to minimize or eliminate income taxes on such gains. The Company considers market factors and its performance in addition to REIT requirements in determining its distribution levels. Amounts accumulated for distribution to stockholders are invested primarily in interest-bearing accounts and short-term interest-bearing securities, which is consistent with the Company’s intention to maintain its qualification as a REIT. Such investments may include, for example, obligations of the Government National Mortgage Association, other governmental agency securities, certificates of deposit, and interest-bearing bank deposits.

On December 10, 2020, the Board of Directors declared a regular quarterly cash dividend of $0.50 per share of common stock. The regular quarterly cash dividend is payable to stockholders of record on December 31, 2020 and a corresponding cash distribution of $0.50 per Operating Partnership units is payable to holders of the Operating Partnership’s common limited partnership interests of record on December 31, 2020, including those owned by the Company. The total cash quarterly dividends and distributions paid on January 15, 2021 were $58.6 million.

Debt Covenants

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

Capitalization

As of December 31, 2020, our total debt as a percentage of total market capitalization was 37.0%, which was calculated based on the closing price per share of the Company’s common stock of $57.40 on December 31, 2020 as shown in the following table:

Liquidity and Capital Resources of the Operating Partnership

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

General

Our primary liquidity sources and uses are as follows:

Liquidity Sources

•Net cash flow from operations;

•Borrowings under the Operating Partnership’s unsecured revolving credit facility;

•Proceeds from our capital recycling program, including the disposition of assets and the formation of strategic ventures;

•Proceeds from additional secured or unsecured debt financings; and

•Proceeds from public or private issuance of debt, equity or preferred equity securities.

Liquidity Uses

•Development and redevelopment costs;

•Operating property or undeveloped land acquisitions;

•Property operating and corporate expenses;

•Capital expenditures, tenant improvement and leasing costs;

•Debt service and principal payments, including debt maturities;

•Distributions to common security holders;

•Repurchases and redemptions of outstanding common stock of the Company; and

•Outstanding debt repurchases, redemptions and repayments.

General Strategy

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

2020 Capital and Financing Transactions

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

Capital Recycling Program

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

Capital Markets / Debt Transactions

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

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

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

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

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

(2)Our unsecured revolving credit facility interest rate was calculated based on the contractual rate of LIBOR plus 1.000% as of December 31, 2020 and 2019, respectively.

(3)Our facility fee is paid on a quarterly basis and is calculated based on the total borrowing capacity. In addition to the facility fee, we incurred debt origination and legal costs. As of December 31, 2020 and 2019, $2.1 million and $3.4 million of unamortized deferred financing costs, respectively, which are included in prepaid expenses and other assets, net on our consolidated balance sheets, remained to be amortized through the maturity date of our unsecured revolving credit facility.

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, to potentially repay long-term debt and to supplement cash balances given uncertainties and volatility in market conditions.

In August 2020, the Company repaid in full the $150.0 million unsecured term loan facility. The following table summarizes the balance and terms of our unsecured term loan facility as of December 31, 2019:

(2)Our unsecured term loan facility interest rate was calculated based on the contractual rate of LIBOR plus 1.100% as of December 31, 2019.

Capital Recycling Program

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

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

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

Forward Equity Offering and Settlement

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

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

At-The-Market Stock Offering Program

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

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

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

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

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


	Year Ended December 31, 2020
	(in millions, except share and per share data)
Shares of common stock settled during the year	3,147,110
Weighted average price per share of common stock	$	80.08
Aggregate gross proceeds	$	252.0
Aggregate net proceeds after selling commissions	$	247.3

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

Shelf Registration Statement

The Company is a well-known seasoned issuer and the Company and the Operating Partnership have an effective shelf registration statement that provides for the public offering and sale from time to time by the Company of its preferred stock, common stock, depository shares and guarantees of debt securities and by the Operating Partnership of its debt securities, in each case in unlimited amounts. The Company evaluates the capital markets on an ongoing basis for opportunities to raise capital, and, as circumstances warrant, the Company and the Operating Partnership may issue securities of all of these types in one or more offerings at any time and from time to time on an opportunistic basis, depending upon, among other things, market conditions, available pricing and capital needs. During the year ended December 31, 2020, the Company’s stock price ranged from $46.46 to $88.28, a 90% swing, as a result of COVID-19 and the resultant impact on the capital markets and economy. If current conditions continue for an extended period of time, capital raising could be more challenging than under conditions prior to COVID-19. When the Company receives proceeds from the sales of its preferred or common stock, it generally

contributes the net proceeds from those sales to the Operating Partnership in exchange for corresponding preferred or common partnership units of the Operating Partnership. The Operating Partnership may use these proceeds and proceeds from the sale of its debt securities to repay debt, including borrowings under its unsecured revolving credit facility, to develop new or existing properties, to make acquisitions of properties or portfolios of properties, or for general corporate purposes.

Unsecured Senior Notes - Registered Offering

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

Unsecured Senior Notes - Private Placement

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

Unsecured and Secured Debt

The aggregate principal amount of the unsecured and secured debt of the Operating Partnership outstanding as of December 31, 2020 was as follows:

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

Other Liquidity Uses

Development

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

borrowings under the unsecured revolving credit facility, the public or private issuance of debt or equity securities, the disposition of assets under our capital recycling program, or strategic venture opportunities.

Debt Maturities

We believe our conservative leverage and staggered debt maturities provide us with financial flexibility and enhance our ability to obtain additional sources of liquidity if necessary, and, therefore, we believe we are well-positioned to refinance or repay maturing debt and to pursue our strategy of seeking attractive acquisition opportunities, which we may finance, as necessary, with future public and private issuances of debt and equity securities. However, we can provide no assurance that we will have access to the public or private debt or equity markets in the future on favorable terms or at all. Refer to “Part I, Item IA. Risk Factors” included in this report for additional information about the potential impact of the COVID-19 pandemic, and restrictions intended to prevents its spread, on our business, financial condition, results of operations, cash flows, liquidity and ability to satisfy our debt service obligations and to pay dividends and distributions to security holders. Our next debt maturity occurs in July 2022 and relates to our unsecured revolving credit facility, under which we currently do not have any amounts borrowed.

Potential Future Acquisitions

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

As discussed in the section “—Factors That May Influence Future Results of Operations - Acquisitions,” we continue to evaluate strategic opportunities and remain a disciplined buyer of development and redevelopment opportunities as well as value-add operating properties, dependent on market conditions and business cycles, among other factors. We focus on growth opportunities in West Coast markets populated by knowledge and creative based tenants in a variety of industries, including technology, media, healthcare, life sciences, entertainment and professional services. Any material acquisitions will be funded with borrowings under the unsecured revolving credit facility, the public or private issuance of debt or equity securities, the disposition of assets under our capital recycling program, the formation of strategic ventures or through the assumption of existing debt. We cannot provide assurance that we will enter into any agreements to acquire properties, or undeveloped land, or that the potential acquisitions contemplated by any agreements we may enter into in the future will be completed.

Share Repurchases

As of December 31, 2020, 4,935,826 shares remained eligible for repurchase under a share repurchase program approved by the Company’s board of directors in 2016. Under this program, repurchases may be made in open market transactions at prevailing prices or through privately negotiated transactions. We may elect to repurchase shares of our common stock under this program in the future depending upon various factors, including market conditions, the trading price of our common stock and our other uses of capital. This program does not have a termination date, and repurchases may be discontinued at any time. We intend to fund repurchases, if any, primarily with the proceeds from property dispositions.

Potential Future Leasing Costs and Capital Improvements

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

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

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

_____________________

(1)Excludes development properties and includes 100% of consolidated property partnerships.

(2)Includes tenants with lease terms of 12 months or longer. Excludes leases for month-to-month and first generation tenants.

(3)Excludes leases for which the space was vacant for longer than one year, or vacant when the property was acquired by the Company.

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

Distribution Requirements

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

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

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

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

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

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

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

Debt Covenants

The unsecured revolving credit facility, unsecured term loan facility, unsecured term loan, unsecured senior notes and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements. Key existing financial covenants and their covenant levels include:

Unsecured Credit and Private Placement Notes (as defined in the applicable Credit Agreements):

3.2x

Unsecured debt ratio

greater than 1.67x

3.09x

3.98x

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

Total debt to total asset value

35%

Interest coverage

greater than 1.5x

8.1x

Secured debt to total asset value

less than 40%

Unencumbered asset pool value to unsecured debt

greater than 150%

297%

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

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

Consolidated Historical Cash Flow Summary

The following summary discussion of our consolidated historical cash flow is based on the consolidated statements of cash flows in Item 15. “Exhibits and Financial Statement Schedules” and is not meant to be an all-inclusive discussion of the changes in our cash flow for the periods presented below. Changes in our cash flow include changes in cash and cash equivalents and restricted cash. Our historical cash flow activity for the year ended December 31, 2020 as compared to the year ended December 31, 2019 is as follows:


	Year Ended December 31,
	2020		2019		Dollar Change		Percentage Change
	($ in thousands)
Net cash provided by operating activities	$	455,590	$	386,521	$	69,069	17.9	%
Net cash used in investing activities	(542,128)		(1,228,279)		686,151		(55.9)	%
Net cash provided by financing activities	833,324		747,068		86,256		11.5	%
Net increase (decrease) in cash and cash equivalents	$	746,786	$	(94,690)	$	841,476	888.7	%

Operating Activities

Our cash flows from operating activities depends on numerous factors including the occupancy level of our portfolio, the rental rates achieved on our leases, the collectability of rent and recoveries from our tenants, the level of operating expenses, the impact of property acquisitions, completed development projects and related financing activities, and other general and administrative costs. Our net cash provided by operating activities increased by $69.1 million, or 17.9%, for the year ended December 31, 2020 compared to the year ended December 31, 2019 primarily as a result of net changes in other assets related to the timing of expenditures and net cash flow from operations of development properties that became stabilized during the year ended December 31, 2020.

Investing Activities

Our cash flows from investing activities is generally used to fund development and operating property acquisitions, expenditures for development projects, and recurring and nonrecurring capital expenditures for our operating properties, net of proceeds received from dispositions of real estate assets. Our net cash used in investing activities decreased by $686.2 million, or 55.9%, for the year ended December 31, 2020 compared to the year ended December 31, 2019, primarily due to lower expenditures for development properties and undeveloped land, no acquisitions completed and lower disposition activity during the year ended December 31, 2020.

Financing Activities

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

Off-Balance Sheet Arrangements

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

Non-GAAP Supplemental Financial Measure: Funds From Operations

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

The following table presents our FFO for the years ended December 31, 2020, 2019, 2018, 2017 and 2016:

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 new requirement to describe critical audit matters arising from the audit of the current period’s financial statements in the auditor’s report. The requirements related to critical audit matters in AS 3101 were effective for audits of fiscal years ending on or after June 30, 2019, for large accelerated filers; and for fiscal years ending on or after December 15, 2020, for all other companies to which the requirements apply. Therefore, critical audit matters are included in the Report of Independent Registered Public Accounting Firm for the Company’s and the Operating Partnership’s consolidated financial statements as of and for the years ended December 31, 2020.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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

Interest Rate Risk

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

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

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

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

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

ITEM 9A. CONTROLS AND PROCEDURES

Kilroy Realty Corporation

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

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

Changes in Internal Control Over Financial Reporting

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

Management’s Report on Internal Control Over Financial Reporting

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

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

Deloitte & Touche LLP, the Company’s independent registered public accounting firm, has audited the Company’s financial statements and has issued a report on the effectiveness of the Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of

Kilroy Realty Corporation

Opinion on Internal Control over Financial Reporting

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

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

Basis for Opinion

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

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

Definition and Limitations of Internal Control over Financial Reporting

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

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of

Kilroy Realty Corporation

Opinion on the Financial Statements

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

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

Basis for Opinion

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

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

Critical Audit Matter

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

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

Critical Audit Matter Description

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

F - 2

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

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

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

How the Critical Audit Matter Was Addressed in the Audit

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

•We tested the effectiveness of controls over revenue recognition, including those over the ownership of tenant improvements and the determination of when the tenant took possession of or controlled the leased space.

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

–Evaluating the Company’s and the tenant’s respective obligations as governed by the lease agreements for selected leases against criteria for establishing ownership.

–Testing documentation supporting the nature of tenant improvements.

–Performing on-site inspections of selected development properties, as needed, to evaluate the nature of tenant improvements, particularly the uniqueness of the improvements.

•We evaluated the reasonableness of management’s conclusions regarding the possession of or control of the completed leased space and corresponding commencement of rental revenue recognition for development properties by:

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

–Performing on-site inspections of selected development properties near the planned rental revenue recognition commencement date, as needed, to observe the status of the site and tenant improvements to evaluate whether control of the leased space had been or was ready to be transferred to the tenant.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Partners of

Kilroy Realty, L.P.

Opinion on the Financial Statements

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

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

Basis for Opinion

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

Critical Audit Matter

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

Critical Audit Matter Description

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

F - 8

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

How the Critical Audit Matter Was Addressed in the Audit

•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.

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

1.Organization and Ownership

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

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

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


	Number of Buildings	Rentable Square Feet (unaudited)	Number of Tenants	Percentage Occupied (unaudited) (1)		Percentage Leased (unaudited)

(1)Estimated rentable square feet upon completion.

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

Our stabilized portfolio also excludes our future development pipeline, which as of December 31, 2020 was comprised of five future development sites, representing approximately 61 gross acres of undeveloped land.

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

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

2. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

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

Partially Owned Entities and Variable Interest Entities

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

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

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

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

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

Accounting Pronouncements Adopted January 1, 2020

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

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

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

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

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

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

COVID-19 Lease Modification Accounting Relief

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

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

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

F - 17

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

Significant Accounting Policies

Revenue Recognition

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

Base Rent

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

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

Additional Rent - Reimbursements from Tenants

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

F - 18

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Other Property Income

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

Uncollectible Lease Receivables and Allowances for Tenant and Deferred Rent Receivables

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

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

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 business combinations at fair value at the acquisition date. Transaction costs associated with asset acquisitions, including costs incurred during negotiation, are capitalized in addition to the purchase price of the acquisition.

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

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

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

Operating Properties

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

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

Cost Capitalization

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

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

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

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

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

Once major base building construction activities have ceased and the development or redevelopment property or phases of the development or redevelopment project is placed in service, which may occur in phases or for an entire building or project, the costs capitalized to construction in progress are transferred to land and improvements, buildings and improvements, and deferred leasing costs on our consolidated balance sheets as the historical cost of the property.

Depreciation and Amortization of Buildings and Improvements

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


Asset Description						Depreciable Lives
Buildings and improvements						25 – 40 years
Tenant improvements						1 – 20 years (1)

____________________

(1)Tenant improvements are amortized over the shorter of the lease term or the estimated useful life.

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 record depreciation and amortization expense. Real estate assets held for sale are reported at the lower of their carrying value or their estimated fair value less the estimated costs to sell. As of December 31, 2020 and 2019, we did not have any properties classified as held for sale.

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

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

Cash and Cash Equivalents

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

Restricted Cash

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

Marketable Securities / Deferred Compensation Plan

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

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

Deferred Leasing Costs

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

Deferred Financing Costs

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

Debt Discounts and Premiums

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

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

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

F - 23

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

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

Noncontrolling Interests in Consolidated Property Partnerships

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

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

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

Noncontrolling Interests on the Operating Partnership’s Consolidated Financial Statements

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

Equity Offerings

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

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

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

Share-based Incentive Compensation Accounting

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

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

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

In accordance with the provisions of our share-based incentive compensation plan, we accept the return of shares of Company common stock, at the current quoted market price, from employees to satisfy minimum statutory tax-withholding requirements related to shares that vested during the period.

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

Basic and Diluted Net Income Available to Common Stockholders per Share

Basic net income available to common stockholders per share is computed by dividing net income available to common stockholders, after preferred distributions and the allocation of income to participating securities, by the

F - 25

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

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

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

Basic and Diluted Net Income Available to Common Unitholders per Unit

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

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

Fair Value Measurements

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

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

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

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

F - 26

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

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

We determine the fair value for the marketable securities using quoted prices in active markets for identical assets. Our other financial instruments, which are only disclosed at fair value, are comprised of secured debt, unsecured senior notes, unsecured line of credit and unsecured term loan facility.

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

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

Income Taxes

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

In addition, any taxable income from our taxable REIT subsidiaries, which were formed in 2002, 2018, 2019 and 2020, are subject to federal, state, and local income taxes. For the years ended December 31, 2020, 2019 and 2018 the taxable REIT subsidiaries had de minimis taxable income.

Uncertain Tax Positions

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

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

Use of Estimates

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

Segments

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

Concentration of Credit Risk

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

We have deposited cash with financial institutions that is insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 per institution. As of December 31, 2020 and 2019, we had cash accounts in excess of FDIC insured limits.

8. Secured and Unsecured Debt of the Company

In this Note 8, the “Company” refers solely to Kilroy Realty Corporation and not to any of our subsidiaries. The Company itself does not hold any indebtedness. All of our secured and unsecured debt is held directly by the Operating Partnership.

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

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

Debt Covenants and Restrictions

One of the covenants contained within the unsecured revolving credit facility as discussed further below in Note 9 prohibits the Company from paying dividends during an event of default in excess of an amount which results in distributions to us in an amount sufficient to permit us to pay dividends to our stockholders that we reasonably believe are necessary to (a) maintain our qualification as a REIT for federal and state income tax purposes and (b) avoid the payment of federal or state income or excise tax.

9. Secured and Unsecured Debt of the Operating Partnership

(3)The secured debt and the related properties that secure this debt are held in a special purpose entity and the properties are not available to satisfy the debts and other obligations of the Company or the Operating Partnership.

The Operating Partnership’s secured debt was collateralized by operating properties with a combined net book value of approximately $222.0 million as of December 31, 2020.

Although our mortgage loans are secured and non-recourse to the Company and the Operating Partnership, the Company provides limited customary secured debt guarantees for items such as voluntary bankruptcy, fraud, misapplication of payments and environmental liabilities.

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

Unsecured Senior Notes - Registered Offerings

In September 2019, the Operating Partnership issued $500.0 million of aggregate principal amount of unsecured senior notes in a registered public offering. The outstanding balance of the unsecured senior notes is included in unsecured debt, net of an initial issuance discount of $0.6 million, on our consolidated balance sheets. The unsecured senior notes, which are scheduled to mature on February 15, 2030, require semi-annual interest payments each February and August based on a stated annual interest rate of 3.050%. The Operating Partnership may redeem the notes at any time prior to February 15, 2030, either in whole or in part, subject to the payment of an early redemption premium prior to a par call option period commencing three months prior to maturity.

Unsecured Senior Notes - Private Placement

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

Unsecured Senior Notes - Early Redemption

In December 2018, at our option, we early redeemed the $250.0 million aggregate principal amount of our outstanding 6.625% unsecured senior notes that were scheduled to mature on June 1, 2020. In connection with our early redemption, we incurred a $12.6 million loss on early extinguishment of debt comprised of an $11.8 million premium paid to the note holders at the redemption date and a $0.8 million write-off of the unamortized discount and unamortized deferred financing costs.

Unsecured Senior Notes

The following table summarizes the balance and significant terms of the registered unsecured senior notes issued by the Operating Partnership and outstanding, including the issuances noted above, and including unamortized discounts of $8.3 million and $6.5 million and unamortized deferred financing costs of $21.6 million and $18.7 million as of December 31, 2020 and 2019, respectively:

Debt Covenants and Restrictions

The unsecured revolving credit facility, the unsecured senior notes, the Series A and B Notes due 2026, Series A and B Notes due 2027 and 2029, and Notes due 2031 and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements.

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

Common Units of the Operating Partnership

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

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

Noncontrolling Interest in Consolidated Property Partnerships

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

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

Forward Equity Offerings and Settlements

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

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

At-The-Market Stock Offering Programs

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

Since commencement of the 2018 At-The-Market program through December 31, 2020, we have sold 3,594,576 shares of common stock under the 2018 At-The-Market Program. As of December 31, 2020, we may offer and sell shares of our common stock having an aggregate gross sales price up to approximately $214.2 million under the 2018 At-The-Market Program.

The Company did not complete any direct sales of common stock under the program during the years ended December 31, 2020 and 2019. During the year ended December 31, 2018, we sold 447,466 shares of common stock under the 2018 At-The-Market Program and 1,369,729 shares of common stock under the 2014 At-The-Market Program. The following table sets forth information regarding direct sales of our common stock under our at-the-market offering programs for the year ended December 31, 2018:

The proceeds from sales were used to fund development expenditures and general corporate purpose. Actual future sales will depend upon a variety of factors, including, but not limited to, market conditions, the trading price of the Company's common stock and our capital needs. We have no obligation to sell the remaining shares available for sale under the 2018 At-The-Market Program.

15. Share-Based and Other Compensation

Stockholder Approved Share-Based Incentive Compensation Plan

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

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

2020, 2019 and 2018 Share-Based Compensation Grants

In January 2020, the Executive Compensation Committee of the Company’s Board of Directors awarded 263,626 restricted stock units (“RSUs”) to certain officers of the Company under the 2006 Plan, which included 154,267 RSUs (at the target level of performance) that are subject to market and/or performance-based vesting requirements (the “2020 Performance-Based RSUs”) and 109,359 RSUs that are subject to time-based vesting requirements (the “2020 Time-Based RSUs”). During the year ended December 31, 2020, 5,148 2020 Time-Based RSUs, 12,263 2020 Performance-Based RSUs and 6,441 time-based and performance-based RSUs that were granted in prior years were forfeited.

In February 2019, the Executive Compensation Committee of the Company’s Board of Directors awarded 288,378 RSUs to certain officers of the Company under the 2006 Plan, which included 143,396 RSUs (at the target level of performance) that are subject to market and/or performance-based vesting requirements (the “2019 Performance-Based RSUs”) and 144,982 RSUs that are subject to time-based vesting requirements (the “2019 Time-Based RSUs”). During the year ended December 31, 2019, 10,733 2019 Time-Based RSUs, 24,353 2019 Performance-Based RSUs and 98,844 time vest and performance RSUs that were granted in prior years were forfeited.

In connection with entering into an amended employment agreement (the “Amended Employment Agreement”), on December 27, 2018, the Compensation Committee of the Company’s Board of Directors awarded John Kilroy, the Chairman of the Board of Directors and Chief Executive Officer of the Company and the Operating Partnership, 483,871 RSUs, providing an additional retention incentive during the term of the agreement and enticing Mr. Kilroy to delay his retirement. Of these RSUs awarded, 266,130 RSUs (at the target level of performance) are subject to market-based vesting requirements and 217,741 RSUs are subject to time-based vesting requirements. In addition to Mr. Kilroy’s award, the Compensation Committee of the Company’s Board of Directors awarded 161,290 RSUs to certain members of management. Of these RSUs awarded, 80,647 RSUs (at the target level of performance) are subject to market-based vesting requirements (together totaling 346,777 target RSUs with Mr. Kilroy’s award, the “December 2018 Market-Based RSUs”) and 80,643 RSUs are subject to time-based vesting requirements (together totaling 298,384 RSUs with Mr. Kilroy’s award, the “December 2018 Time-Based RSUs”).

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

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

December 2018 Market-Based RSU Grant

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

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


						December 2018 Market-Based RSU Award Fair Value Assumptions
Valuation date						December 27, 2018
Fair value per share on valuation date						$68.66
Expected share price volatility						23.0%
Risk-free interest rate						2.4%

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

2020, 2019 and 2018 Annual Performance-Based RSU Grants

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

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

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

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

As of December 31, 2020, the estimated number of RSUs earned for the 2020 and 2019 Performance-Based RSUs and the actual number of RSUs earned for the 2018 Performance-Based RSUs was as follows:

(1)Estimated RSUs earned for the 2020 Performance-Based RSUs are based on the actual achievement of the 2020 FFO Performance Condition and for the 2020 Debt to EBITDA Ratio Performance Condition, assumes 100% of the target level of achievement for all participants, and target level of achievement of the 2020 Market Condition. Estimated RSUs earned for the 2019 Performance-Based RSUs are based on the actual achievement of the 2019 FFO Performance Condition and assume target level achievement of the 2019 Market Condition and maximum level of achievement of the 2019 Debt to EBITDA Ratio Performance Condition. The 2018 Performance-Based RSUs earned are based on actual performance of the 2018 Performance Conditions and the 2018 Market Condition.

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


	2020 Award Fair Value Assumptions	2019 Award Fair Value Assumptions	2018 Award Fair Value Assumptions
Valuation date	January 31, 2020	February 1, 2019	February 14, 2018
Fair value per share on valuation date	$84.54	$72.57	$70.08
Expected share price volatility	17.0%	19.0%	20.0%
Risk-free interest rate	1.35%	2.48%	2.37%

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

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

Share-Based Compensation Cost Recorded During the Period

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

Severance Compensation

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

Other Compensation

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

16. Employee Benefit Plans

401(k) Plan

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

Deferred Compensation Plan

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

See Note 19 “Fair Value Measurements and Disclosures” for further discussion of our Deferred Compensation Plan assets as of December 31, 2020 and 2019. Our liability of $27.4 million and $27.0 million under the Deferred Compensation Plan was fully funded as of December 31, 2020 and 2019, respectively.

17. Rental Income and Future Minimum Rent

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

The table below sets forth the allocation of rental income between fixed and variable payments and net collectability reversals or recoveries for the years ended December 31, 2020 and 2019:


	Year Ended December 31,
	2020		2019

Fixed lease payments	$	786,860	$	708,362
Variable lease payments	124,443		115,915
Net collectability (reversals) recoveries (1)	(18,997)		2,195
Total rental income	$	892,306	$	826,472

____________________

(1)Represents adjustments to rental income related to our assessment of the collectability of amounts due under leases with our tenants. For the year ended December 31, 2020, includes $18.4 million of write-offs related to the cumulative impact of transitioning certain tenants to a cash basis of reporting primarily as a result of the COVID-19 pandemic. Also includes a $0.6 million net increase to the allowance for doubtful accounts, which includes the impact of $2.2 million of reversals to the allowance for doubtful account for tenants that had an allowance at January 1, 2020 and were subsequently transitioned to a cash basis of reporting during 2020. These reversals are included in the $18.4 million of write-offs above.

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

18. Commitments and Contingencies

General

As of December 31, 2020, we had commitments of approximately $614.9 million, excluding our ground lease commitments, for contracts and executed leases directly related to our operating and development properties.

Ground Leases

The following table summarizes our properties that are held subject to long-term noncancellable ground lease obligations and the respective contractual expiration dates:


Property			Contractual Expiration Date (1)
601 108th Ave NE, Bellevue, WA			November 2093
701, 801 and 837 N. 34th Street, Seattle, WA (2)			December 2041

3243 S. La Cienega Boulevard, Los Angeles, CA (3)			October 2106

____________________

(1) Reflects the contractual expiration date prior to the impact of any extension or purchase options held by the Company.

(2) The Company has three 10-year and one 45-year extension options for this ground lease, which if exercised would extend the expiration date to December 2116. These extension options are not assumed to be exercised in our calculation of the present value of the future minimum lease payments for this lease.

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

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

(2) One of our ground lease obligations is subject to a fair market value adjustment every five years; however, the lease includes ground rent subprotection and infrastructure rent credits which currently limit our annual rental obligations to $1.0 million. The contractual obligations for that ground lease included above assumes the lesser of $1.0 million or annual lease rental obligation in effect as of December 31, 2020.

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

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

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

(6) One of our ground lease obligations is subject to fixed 5% ground rent increases every five years, with the next increase occurring on December 1, 2022.

Environmental Matters

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

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

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

F - 55

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

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

Other than the accrued environmental liabilities discussed above, we are not aware of any unasserted claims and assessments with respect to an environmental liability that we believe would require additional disclosure or the recording of an additional loss contingency.

Litigation

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

Insurance

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

Share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are considered participating securities. The impact of potentially dilutive common units, including stock options, RSUs, shares issuable under executed forward equity sale agreements, if any, and other securities are considered in our diluted earnings per share calculation for the years ended December 31, 2020, 2019 and 2018. Certain market measure-based RSUs are not included in dilutive securities as of December 31, 2020, 2019 and 2018 as not all performance metrics had been met by the end of the applicable reporting periods.

See Note 15 “Share-Based and Other Compensation” for additional information regarding the stock options and other share-based compensation.

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

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