Letter to 
Shareholders

Dear fellow shareholders,

2020 was a challenging year for all companies, with the 
COVID-19 pandemic emerging in late February, shutting down 
many businesses and interrupting global commerce. For 
our Company, 2020 was a challenging yet strong year. We 
derive nearly 90% of our rents from locations that support the 
defense activities of the U.S. Government and its contractors 
engaged in national security, defense information technology, 
and cybersecurity activities, among others. Our strategy of 
concentrating buildings around U.S. defense installations 
executing priority missions is unique in the REIT industry, and 
our performance during the economic uncertainty caused by 
the COVID-19 pandemic and related shutdowns demonstrated 
the strength of this strategy.

Rent collections remained very high throughout the shutdowns 
due to the exceptional credit quality of our tenants, and we 
made only limited collection accommodations, mostly to retail 
and amenity tenants to help them bridge the financial gap 
caused by the shutdowns. Other pandemic-related impacts our 
operations absorbed during the year included a $1.9 million 
decrease in parking revenue and a $2.8 million increase in 
provisions for collectability losses for our Same Properties pool 
relative to the prior year. 

Notwithstanding these impacts, we met or exceeded 
performance expectations, with our actual results of $2.12 
of diluted FFO per share, as adjusted for comparability, for 
the year exceeding the midpoint of our initial pre-pandemic 
guidance by 4-cents and representing 4.4% growth over 
2019 results.

At the end of 2020, our total portfolio was 94.1% occupied 
and 94.8% leased, representing gains of 120 basis points 
and 40 basis points, respectively. These year-over-year gains 
were led by strong increases at The National Business Park 
(part of our Ft. Meade/BW Corridor sub-segment), and in 
our Northern Virginia Defense/IT and Navy Support sub-
segments. Additionally, development success in our Redstone 
Arsenal sub-segment nearly doubled the size of our Redstone 
Gateway operations, to 1.5 million square feet that were near 
full occupancy.

During the year, we raised debt and equity capital on 
attractive terms. In September we issued $400 million of 
senior unsecured notes at an interest rate of 2.25%. This 
was our first bond issuance since June 2015, and the 
transaction received a very positive response from investors

Vacancy leasing volume was the area most significantly

current development projects to drive FFO per share between 

2–5% higher than 2020’s elevated results. In short, we believe 

that our Company has entered a new cycle of growth, driven

a reliable low-risk development program that is producing 

incremental NOI annually.

In contrast, development demand was strong throughout the 

year, and we met our pre-pandemic goal of leasing one million 

square feet (see Figure 1). These development leases included 

five, fully leased build-to-suit projects for defense contractors 

totaling 680,000 square feet at four of our six Defense/IT 

extraordinary. They exceeded the already high service 

levels expected by the tenants we support, which in turn 

gave these tenants the confidence to safely remain in their 

spaces, executing their vital missions for our country. For 

these efforts and those of our entire team, I am extremely 

humbled and grateful.

River portion of our Navy Support sub-segment.

Most importantly, we placed 1.8 million square feet that were 

fully leased into service during the year, surpassing the prior 

Company record by more than 600,000 square feet (see 

Figure 2). Our ability to place large volumes of highly leased 

developments into service is a primary driver of our long-

term growth. We believe that NOI from these developments 

in 2021 will more than offset the effects of 2020’s delayed 

vacancy leasing.

National defense spending drives demand for our Defense/

IT Locations, and the defense spending environment remains 

healthy. Congress appropriated the fiscal year 2021 defense 

budget on January 1, 2021, with solid bi-partisan support.

The aggregate market value of the voting and nonvoting shares of common stock held by non-affiliates of Corporate Office Properties Trust was 

approximately $2.2 billion, as calculated using the closing price of such shares on the New York Stock Exchange as of  and the number of outstanding shares as of 
June 30, 2020.  For purposes of calculating this amount only, affiliates are defined as Trustees, executive owners and beneficial owners of more than 10% of 
Corporate Office Properties Trust’s outstanding common shares, $0.01 par value.  At January 22, 2021, 112,181,219 of Corporate Office Properties Trust’s 
common shares were outstanding.  

The aggregate market value of the voting and nonvoting common units of limited partnership interest held by non-affiliates of Corporate Office Properties, 
L.P. was approximately $24.2 million, as calculated using the closing price of the common shares of Corporate Office Properties Trust (into which common units 
not held by Corporate Office Properties Trust are exchangeable) on the New York Stock Exchange as of June 30, 2020 and the number of outstanding units as of 
June 30, 2020.

Portions of the proxy statement of Corporate Office Properties Trust for its 2021 Annual Meeting of Shareholders to be filed within 120 days after the end of 

the fiscal year covered by this Form 10-K 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 Corporate Office Properties Trust 
(“COPT”) and subsidiaries (collectively, the “Company”) and Corporate Office Properties, L.P. (“COPLP”) and subsidiaries (collectively, the 
“Operating Partnership”).  Unless stated otherwise or the context otherwise requires, “we,” “our,” and “us” refer collectively to COPT, COPLP 
and their subsidiaries. 

COPT is a real estate investment trust, or REIT, and the sole general partner of COPLP.  As of December 31, 2020, COPT owned 98.6% of 

the outstanding common units in COPLP; the remaining common units and all of the outstanding COPLP preferred units were owned by third 
parties.  As the sole general partner of COPLP, COPT controls COPLP and can cause it to enter into 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 which are reflected 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 two operate as an 
interrelated, consolidated company.  COPT is a REIT whose only material asset is its ownership of partnership interests of COPLP.  As a result, 
COPT does not conduct business itself, other than acting as the sole general partner of COPLP, issuing public equity and guaranteeing certain 
debt of COPLP.  COPT itself is not directly obligated under any indebtedness but guarantees some of the debt of COPLP.  COPLP owns 
substantially all of the assets of COPT either directly or through its subsidiaries, conducts almost all of the operations of the business and is 
structured as a limited partnership with no publicly traded equity.  Except for net proceeds from public equity issuances by COPT, which are 
contributed to COPLP in exchange for partnership units, COPLP generates the capital required by COPT’s business.  

Noncontrolling interests, shareholders’ equity and partners’ capital are the main areas of difference between the consolidated financial 
statements of COPT and those of COPLP.  The common limited partnership interests in COPLP not owned by COPT are accounted for as 
partners’ capital in COPLP’s consolidated financial statements and as noncontrolling interests in COPT’s consolidated financial statements.  The 

 
 
            
 
 
 
 
only other significant differences between the consolidated financial statements of COPT and those of COPLP are assets in connection with a 
non-qualified elective deferred compensation plan and the corresponding liability to the plan’s participants that are held directly by COPT. 

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

•
•

•

•

Note 3, Fair Value Measurements of COPT and subsidiaries and COPLP and subsidiaries;
Note 9, Prepaid Expenses and Other Assets, Net of COPT and subsidiaries and COPLP and subsidiaries;
Note 13, Equity of COPT and subsidiaries;
Note 14, Equity of COPLP and subsidiaries; and
Note 19, Earnings per Share of COPT and subsidiaries and Earnings per Unit of COPLP and subsidiaries;

consolidated financial statements; 
the following notes to the consolidated financial statements: 
•
•
•
•
•
“Item 7: Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources of 
COPT”; and 
“Item 7: Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources of 
COPLP.” 

This report also includes separate sections under Part II, Item 9A. Controls and Procedures and separate Exhibit 31 and Exhibit 32 certifications 
for each of COPT and COPLP to establish that the Chief Executive Officer and the Chief Financial Officer of each entity have made the 
requisite certifications and that COPT and COPLP are compliant with Rule 13a-15 and Rule 15d-14 of the Securities Exchange Act of 1934, as 
amended (the “Exchange Act”), and 18 U.S.C. §1350.

Forward-looking Statements

This Form 10-K contains “forward-looking” statements, as defined in the Private Securities Litigation Reform Act of 1995, 

that are based on our current expectations, estimates and projections about future events and financial trends affecting the 
financial condition and operations of our business.  Additionally, documents we subsequently file with the SEC and 
incorporated by reference will contain forward-looking statements.

Forward-looking statements can be identified by the use of words such as “may,” “will,” “should,” “could,” “believe,” 
“anticipate,” “expect,” “estimate,” “plan” or other comparable terminology.  Forward-looking statements are inherently subject 
to risks and uncertainties, many of which we cannot predict with accuracy and some of which we might not even anticipate.  
Although we believe that the expectations, estimates and projections reflected in such forward-looking statements are based on 
reasonable assumptions at the time made, we can give no assurance that these expectations, estimates and projections will be 
achieved.  Future events and actual results may differ materially from those discussed in the forward-looking statements. We 
caution readers that forward-looking statements reflect our opinion only as of the date on which they were made. You should 
not place undue reliance on forward-looking statements.  The following factors, among others, could cause actual results and 
future events to differ materially from those set forth or contemplated in the forward-looking statements:

may not be completed on schedule, that tenants may not take occupancy or pay rent or that development or operating costs 
may be greater than anticipated;
risks of investing through joint venture structures, including risks that our joint venture partners may not fulfill their 
financial obligations as investors or may take actions that are inconsistent with our objectives;
changes in our plans for properties or views of market economic conditions or failure to obtain development rights, either 
of which could result in recognition of significant impairment losses;
our ability to satisfy and operate effectively under Federal income tax rules relating to real estate investment trusts and 
partnerships;
possible adverse changes in tax laws;
the dilutive effects of issuing additional common shares;

Item 1. Business

OUR COMPANY

PART I

General.  Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company”) is a fully-integrated 

and self-managed real estate investment trust (“REIT”).  Corporate Office Properties, L.P. (“COPLP”) and subsidiaries 
(collectively, the “Operating Partnership”) is the entity through which COPT, the sole general partner of COPLP, conducts 
almost all of its operations and owns almost all of its assets.  Unless otherwise expressly stated or the context otherwise 
requires, “we”, “us” and “our” as used herein refer to each of the Company and the Operating Partnership.  We own, manage, 
lease, develop and selectively acquire office and data center properties.  The majority of our portfolio is in locations that 
support the United States Government (“USG”) and its contractors, most of whom are engaged in national security, defense and 
information technology (“IT”) related activities servicing what we believe are growing, durable, priority missions (“Defense/IT 
Locations”).  We also own a portfolio of office properties located in select urban/urban-like submarkets in the Greater 
Washington, DC/Baltimore region with durable Class-A office fundamentals and characteristics (“Regional Office”).  As of 
December 31, 2020, our properties included the following:

•

•
•

•

181 properties totaling 21.0 million square feet comprised of 16.2 million square feet in 155 office properties and 4.7 
million square feet in 26 single-tenant data center shell properties (“data center shells”).  We owned 17 of these data center 
shells through unconsolidated real estate joint ventures;
a wholesale data center with a critical load of 19.25 megawatts;
11 properties under development (nine office properties and two data center shells), including three partially-operational 
properties, that we estimate will total approximately 1.5 million square feet upon completion; and
approximately 830 acres of land controlled for future development that we believe could be developed into approximately 
10.4 million square feet and 43 acres of other land.

COPLP owns real estate directly and through subsidiary partnerships and limited liability companies (“LLCs”).  In addition to 
owning real estate, COPLP also owns subsidiaries that provide real estate services such as property management, development 
and construction services primarily for our properties but also for third parties.  Some of these services are performed by a 
taxable REIT subsidiary (“TRS”).

Equity interests in COPLP are in the form of common and preferred units.  As of December 31, 2020, COPT owned 98.6% 
of the outstanding COPLP common units (“common units”) and there were no preferred units outstanding.  Common units not 
owned by COPT carry certain redemption rights.  The number of common units owned by COPT is equivalent to the number of 
outstanding common shares of beneficial interest (“common shares”) of COPT, and the entitlement of common units to 
quarterly distributions and payments in liquidation is substantially the same as that of COPT common shareholders. 

COPT’s common shares are publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “OFC”.

Because COPLP is managed by COPT, and COPT conducts substantially all of its operations through COPLP, we refer to 

COPT’s executive officers as COPLP’s executive officers; similarly, although COPLP does not have a board of trustees, we 
refer to COPT’s Board of Trustees as COPLP’s Board of Trustees.

We believe that COPT is organized and has operated in a manner that satisfies the requirements for taxation as a REIT 
under the Internal Revenue Code of 1986, as amended, and we intend to continue to operate COPT in such a manner.  If COPT 
continues to qualify for taxation as a REIT, it generally will not be subject to Federal income tax on its taxable income (other 
than that of its TRS entities) that is distributed to its shareholders.  A REIT is subject to a number of organizational and 
operational requirements, including a requirement that it distribute at least 90% of its annual taxable income to its shareholders.

Our executive offices are located at 6711 Columbia Gateway Drive, Suite 300, Columbia, Maryland 21046 and our 

telephone number is (443) 285-5400.  

Our Internet address is www.copt.com.  We make available on our Internet website free of charge our annual reports on 
Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished 
pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as soon as 
reasonably possible after we file such material with the Securities and Exchange Commission (the “SEC”).  In addition, we 
have made available on our Internet website under the heading “Corporate Governance” the charters for our Board of Trustees’ 

6

Audit, Nominating and Corporate Governance, Compensation and Investment Committees, as well as our Corporate 
Governance Guidelines, Code of Business Conduct and Ethics and Code of Ethics for Financial Officers.  We intend to make 
available on our website any future amendments or waivers to our Code of Business Conduct and Ethics and Code of Ethics for 
Financial Officers within four business days after any such amendments or waivers.  The information on our Internet site is not 
part of this report.  

The SEC maintains an Internet website that contains reports, proxy and information statements and other information 

regarding issuers that file electronically with the SEC.  This Internet website can be accessed at www.sec.gov. 

Business and Growth Strategies

Our primary goal is to create value and deliver attractive and competitive total returns to our shareholders.  This section 

sets forth key components of our business and growth strategies that we have in place to support this goal. 

Defense/IT Locations Strategy: We specialize in serving the unique requirements of tenants in our Defense/IT Locations 
properties.  These properties are primarily occupied by the USG and contractor tenants engaged in what we believe are high 
priority security, defense and IT missions.  These tenants’ missions pertain more to knowledge- and technology-based activities 
(i.e., cyber security, research and development and other highly technical defense and security areas) than to force structure 
(i.e., troops) and weapon system mass production.  Our office and data center shell portfolio is significantly concentrated in 
Defense/IT Locations, which as of December 31, 2020 accounted for 171 of the portfolio’s 181 properties, representing 87.1% 
of its annualized rental revenue, and we control developable land to accommodate future growth in this portfolio.  These 
properties generally have higher tenant renewal rates than is typical in commercial office space due in large part to: their 
proximity to defense installations or other key demand drivers; the ability of many of these properties to meet Anti-Terrorism 
Force Protection (“ATFP”) requirements; and significant investments often made by tenants for unique needs such as Secure 
Compartmented Information Facility (“SCIF”), critical power supply and operational redundancy. 

In recent years, data center shells have been a significant growth driver for our Defense/IT Locations.  Data center shells 
are properties leased to tenants to be operated as data centers in which we provide tenants with only the core building and basic 
power, while the tenants fund the costs for the critical power, fiber connectivity and data center infrastructure.  From 2013 
through 2020, we placed into service 26 data center shells totaling 4.7 million square feet, and we had an additional two under 
development totaling 420,000 square feet as of December 31, 2020.  We enter into long-term leases for these properties prior to 
commencing development, with triple-net structures and multiple extension options and rent escalators to provide future 
growth.  Additionally, our tenants’ funding of the costs to fully power and equip these properties significantly enhances the 
value of these properties and creates high barriers to exit for such tenants.

We believe that our properties and team collectively complement our Defense/IT Locations strategy due to our:

•

•
•

•

properties’ proximity to defense installations and other knowledge- and technology-based government demand drivers.  
Such proximity is generally preferred and often required for our tenants to execute their missions.  Specifically, our:
•

office properties are proximate to such mission-critical facilities as Fort George G. Meade (which houses over 100 
Department of Defense organizations and agencies, including ones engaged in signals intelligence, such as U.S. Cyber 
Command and Defense Information Systems Agency) and Redstone Arsenal (one of the largest defense installations in 
the United States, housing priority missions such as Army procurement, missile defense, space exploration, and 
research and development, testing and engineering of advanced weapons systems); and
data center shells located in Northern Virginia, proximate to the MAE-East Corridor, which is a major Network Access 
Point in the United States for interconnecting traffic between Internet service providers;

•

well-established relationships with the USG and its contractors;
extensive experience in developing: 
•
•

high quality, highly-efficient office properties;
secured, specialized space, with the ability to satisfy the USG’s unique needs (including SCIF and ATFP 
requirements); and
data center shells to customer specifications within very condensed timeframes to accommodate time-sensitive tenant 
demand; and

•

depth of knowledge, specialized skills and credentialed personnel in operating highly-specialized properties with unique 
security-oriented requirements.

7

Regional Office Strategy: While Defense/IT Locations are our primary focus, we also own a portfolio of office properties 

located in select urban/urban-like submarkets in the Greater Washington, DC/Baltimore region due to our strong market 
knowledge in that region.  We believe that these submarkets possess the following favorable characteristics: (1) mixed-use, 
lifestyle oriented locations with a robust residential and retail base; (2) proximity to public transportation and major 
transportation routes; (3) an educated workforce; and (4) a diverse employment base.  As of December 31, 2020, we owned 
eight Regional Office properties, representing 12.5% of our office and data center shell portfolio’s annualized rental revenue.  
These properties were comprised of: three high-rise Baltimore City properties proximate to the city’s waterfront; four Northern 
Virginia properties proximate to existing or future Washington Metropolitan Area Metrorail stations and major interstates; and 
a newly-developed property in Washington, D.C.’s central business district.

Asset Management Strategy: We aggressively manage our portfolio to maximize the value and operating performance of 
each property through: (1) proactive property management and leasing; (2) maximizing tenant retention in order to minimize 
space downtime and additional capital associated with space rollover; (3) increasing rental rates where market conditions 
permit; (4) leasing vacant space; (5) achievement of operating efficiencies by increasing economies of scale and, where 
possible, aggregating vendor contracts to achieve volume pricing discounts; and (6) redevelopment when we believe property 
conditions and market demand warrant.  We also continuously evaluate our portfolio and consider dispositions when properties 
no longer meet our strategic objectives, or when capital markets and the circumstances pertaining to such holdings otherwise 
warrant, in order to maximize our return on invested capital or support our property development and capital strategy. 

We aim to sustainably develop and operate our portfolio to create healthier work environments and reduce consumption of 
resources by: (1) developing new buildings designed to use resources with a high level of efficiency and low impact on human 
health and the environment during their life cycles through our participation in the U.S. Green Building Council’s Leadership in 
Energy and Environmental Design (“LEED”) program; (2) investing in energy systems and other equipment that reduce energy 
consumption and operating costs; (3) adopting select LEED for Building Operations and Maintenance (“LEED O+M: Existing 
Buildings”) prerequisites for much of our portfolio, including guidelines pertaining to cleaning and recycling practices and 
energy reduction; and (4) participating in the annual Global Real Estate Sustainability Benchmark (“GRESB”) survey, which is 
widely recognized for measuring the environmental, social and governance (“ESG”) performance of real estate companies and 
funds.  We earned an overall score of “Green Star” on the GRESB survey in each of the last six years, representing the highest 
quadrant of achievement on the survey.

Property Development and Acquisition Strategy: We expand our operating portfolio primarily through property 
developments in support of our Defense/IT Locations strategy, and we have significant land holdings that we believe can 
further support that growth while serving as a barrier against competitive supply.  We pursue development activities as market 
conditions and leasing opportunities support favorable risk-adjusted returns on investment, and therefore typically prefer 
properties to be significantly leased prior to commencing development.  To a lesser extent, we may also pursue growth through 
acquisitions, seeking to execute such transactions at attractive yields and below replacement cost.  

Capital Strategy: Our capital strategy is aimed at maintaining continuous access to capital irrespective of market conditions 

in the most cost-effective manner by:  

• maintaining an investment grade rating to enable us to use debt comprised of unsecured, primarily fixed-rate debt 

(including the effect of interest rate swaps) from public markets and banks;
using secured nonrecourse debt from institutional lenders and banks;

•
• managing our debt by monitoring, among other things: (1) the relationship of certain measures of earnings to our debt level 

and to certain capital costs; (2) the timing of debt maturities to ensure that maturities in any one year do not exceed levels 
that we believe we can refinance; (3) our exposure to changes in interest rates; and (4) our total and secured debt levels 
relative to our overall capital structure;
raising equity through issuances of common shares in COPT and common units in COPLP, joint venture structures for 
certain investments and, to a lesser extent, issuances of preferred shares in COPT and preferred units in COPLP;

•

• monitoring capacity available under revolving credit facilities and equity offering programs to provide liquidity to fund 

investment activities;
paying dividends at a level that is at least sufficient for us to maintain our REIT status;
recycling proceeds from sales of interests in properties to fund our investment activities and/or reduce overall debt; and
continuously evaluating the ability of our capital resources to accommodate our plans for growth.

For information relating to our segments, refer to Note 17 to our consolidated financial statements, which is included in a 

separate section at the end of this Annual Report on Form 10-K beginning on page F-1.

Human Capital

Our Workforce:  As of December 31, 2020, our workforce was comprised of 406 employees based in Maryland, where we 

are headquartered, Texas, Virginia, Alabama and Washington, D.C.  Our workforce has varying expertise, and includes:  

•

•
•

•

•
•

•

Building Technicians (175 employees): Skilled trades professionals, who perform mechanical maintenance, maintain our 
operating systems and service our buildings overall.
Operations Management (70 employees): Property managers and support staff who support our tenant customer needs.
Asset Management and Leasing (11 employees): Customer-facing leaders who drive the financial performance of our 
assets.
Development and Construction (30 employees): Project managers and support staff who drive our development pipeline 
and interior design.
Finance and Accounting (65 employees): Professionals who manage our financial activities.
Company Support Functions (42 employees): Includes Human Resources, Investor Relations, Investments, Legal, 
Marketing, Information Technology, Facility Security and Corporate Administrative Support.
Senior Leadership (13 employees): Our business line and Company leaders, including our Named Executive Officers, who 
interface with our Board of Trustees and shareholders and manage our business strategy, functional activities, risk and 
overall success.

In support of our Defense/IT Locations strategy, approximately one-third of our employees carry government credentials.

We operate in markets in which we compete for human capital.  We rely on our employees to drive our success and we 

support them with a variety of programs to enhance their workplace engagement and job fulfillment. 

Culture and Workforce Engagement:  We develop and reinforce our culture by emphasizing our core values, illustrated by 

the actiiVe acronym. actiiVe stands for: Accountability, Commitment, Teamwork, Integrity, Innovation, Value Creation and 
Excellence.  These values are intended to serve as a compass to our workforce to inform behavior and fuel our success.  

We believe in equal opportunity, engagement and ethics.  All employees must adhere to our Code of Business Conduct.  
We survey our workforce annually to measure engagement, use the feedback to enhance engagement and believe that this has 
helped us achieve annual “best workplace” honors for over a decade.  

Compensation Program:  Our compensation philosophy is driven by accountability, which results in a pay-for-performance 

structure.  Our compensation program includes: base salary; an annual cash bonus program based on the achievement of 
individual, business unit and company objectives; health and welfare benefits; a retirement savings plan with a company match; 

9

financially supported learning programs; and employee recognition programs. We also grant common equity to all new full-
time employees and provide our senior leadership and high performers with the ability to earn additional grants to align their 
interests with those of our shareholders and to incent retention.

Wellbeing and Safety:  We view wellbeing as including five pillars: Physical, Emotional, Career, Financial and 

Community.  We design programs to support each of these pillars.  We directly incent wellbeing behaviors through a points-
driven program each year.  Employees who achieve the points threshold receive reductions in medical premiums or funds 
towards their health savings accounts.  We believe this program enhances employee wellbeing and reduces medical costs. 

Safety is a key part of our employee wellbeing, largely weighted in the Physical pillar.  Recognizing this, we conduct job-
tailored safety training on an ongoing basis.  We also monitor our workers’ compensation claims to measure the effectiveness 
of our safety program. 

With wellbeing and safety in mind, during the COVID-19 pandemic in 2020, we:

•
•

•
•
•

consulted with medical experts in developing an approach to safely operate our properties and workplaces;
required our on-site property operations staff to use COPT-provided personal protective equipment, such as masks, gloves 
and hand sanitizer, and implement other procedural changes to enhance separation and minimize spread;
instituted enhanced cleaning measures, particularly for high touch areas and flat surfaces; 
provided signage promoting proper social distancing practices and hand sanitizer stations for property common areas; and
had most of our employees (other than on-site property operations staff) work from home from mid-March until the end of 
May, when most began reporting to their normal work locations on a bi-weekly rotational basis. 

Talent Development:  We aim to attract, retain and develop our top talent throughout the employment cycle in order to 
enhance our talent pool.  During 2020, our workforce grew to support the business’ overall growth and we hired 39 employees.  
In 2020, 27 employees departed the Company, resulting in a 6.75% attrition rate.  

We offer robust learning programs to all employees, including educational assistance for college-level and vocational 
degree programs, and cover all expenses for licenses and certifications, management and leadership courses, key skills training 
and industry and professional conferences.  Further, we offer internship and mentorship programs to facilitate teaching and 
learning from others.

Community Engagement:  We encourage employee engagement with our communities to facilitate personal growth and 

connection and to enhance our citizenship within our communities.  We provide a platform for employees to engage with 
communities by contributing time, effort, money and expertise, which includes providing employees eight hours of paid time 
per year to engage in volunteer activities to serve our community directly, in a company-organized, team or individual format.  
Our employees select community non-profits for Corporate giving grants and for volunteer time contributions.  We empower 
our employees to become involved and fuel our success in community partnerships. 

Competition

The commercial real estate market is highly competitive.  Numerous commercial landlords compete with us for tenants.  

Some of the properties competing with ours may be newer or in more desirable locations, or the competing properties’ owners 
may be willing to accept lower rents.  We also compete with our own tenants, many of whom have the right to sublease their 
space.  The competitive environment for leasing is affected considerably by a number of factors including, among other things, 
changes in economic conditions and supply of and demand for space.  These factors may make it difficult for us to lease 
existing vacant space and space associated with future lease expirations at rental rates that are sufficient to produce acceptable 
operating cash flows. 

We occasionally compete for the acquisition of land and commercial properties with many entities, including other 
publicly-traded commercial REITs.  Competitors for such acquisitions may have substantially greater financial resources than 
ours.  In addition, our competitors may be willing to accept lower returns on their investments or may be willing to incur higher 
leverage.

10

We also compete with many entities, including other publicly-traded commercial office REITs, for capital.  This 

competition could adversely affect our ability to raise capital we may need to fulfill our capital strategy.

In addition, we compete with many entities for talent.  If there is an increase in the costs for us to retain employees or if we 

otherwise fail to attract and retain such employees, our business and operating results could be adversely effected.

Item 1A.  Risk Factors

Set forth below are risks and uncertainties relating to our business and the ownership of our securities.  These risks and 

uncertainties may lead to outcomes that could adversely affect our financial position, results of operations, cash flows and 
ability to make expected distributions to our equityholders.  You should carefully consider each of these risks and uncertainties, 
along with all of the information in this Annual Report on Form 10-K and its Exhibits, including our consolidated financial 
statements and notes thereto for the year ended December 31, 2020 included in a separate section at the end of this report 
beginning on page F-1.

Risks Associated with the Real Estate Industry and Our Properties

Our performance and asset value are subject to risks associated with our properties and with the real estate 

industry.   Real estate investments are subject to various risks and fluctuations in value and demand, many of which are beyond 
our control.  Our performance and the value of our real estate assets may decline due to conditions in the general economy and 
the real estate industry which, in turn, could have an adverse effect on our financial position, results of operations, cash flows 
and ability to make expected distributions to our shareholders.  These conditions include, but are not limited to:

•

•
•
•
•
•
•

•

•

•
•
•
•
•
•
•

downturns in national, regional and local economic environments, including increases in the unemployment rate and 
inflation or deflation;
competition from other properties;
trends in office real estate that may adversely affect future demand, including telecommuting and flexible workplaces; 
deteriorating local real estate market conditions, such as oversupply, reduction in demand and decreasing rental rates;
declining real estate valuations;
adverse developments concerning our tenants, which could affect our ability to collect rents and execute lease renewals;
adverse changes resulting from the COVID-19 pandemic, and similar pandemics, along with restrictive measures instituted 
to prevent spread, on our business, the real estate industry and national, regional and local economic conditions;
government actions and initiatives, including risks associated with the impact of prolonged government shutdowns and 
budgetary reductions or impasses, such as a reduction of rental revenues, non-renewal of leases and/or reduced or delayed 
demand for additional space by our strategic customers;
increasing operating costs, including insurance, utilities, real estate taxes and other expenses, some of which we may not be 
able to pass through to tenants;
increasing vacancies and the need to periodically repair, renovate and re-lease space;
increasing interest rates and unavailability of financing on acceptable terms or at all;
unavailability of financing for potential purchasers of our properties;
adverse changes in taxation or zoning laws;
potential inability to secure adequate insurance;
adverse consequences resulting from civil disturbances, natural disasters, terrorist acts or acts of war; and
potential liability under environmental or other laws or regulations.

Our business may be affected by adverse economic conditions.  Our business may be affected by adverse economic 
conditions in the United States economy or real estate industry as a whole or by the local economic conditions in the markets in 
which our properties are located, including the impact of high unemployment and constrained credit.  Adverse economic 
conditions could increase the likelihood of tenants encountering financial difficulties, including bankruptcy, insolvency or 
general downturn of business, and as a result could increase the likelihood of tenants defaulting on their lease obligations to us.  
Such conditions could also decrease our likelihood of successfully renewing tenants at favorable terms or leasing vacant space 
in existing properties or newly-developed properties.  In addition, such conditions could increase the level of risk that we may 
not be able to obtain new financing for development activities, refinancing of existing debt, acquisitions or other capital 
requirements at reasonable terms, if at all. 

11

We may suffer adverse consequences as a result of our reliance on rental revenues for our income.  We earn revenue 

from renting our properties.  Certain of our operating costs do not necessarily fluctuate in relation to changes in our rental 
revenue.  This means that these costs will not necessarily decline and may increase even if our revenues decline.  

For new tenants or upon expiration of existing leases, we generally must make improvements and pay other leasing costs 

for which we may not receive increased rents.  We also make building-related capital improvements for which tenants may not 
reimburse us. 

If our properties do not generate revenue sufficient to meet our operating expenses and capital costs, we may need to 
borrow additional amounts to cover these costs.  In such circumstances, we would likely have lower profits or possibly incur 
losses.  We may also find in such circumstances that we are unable to borrow to cover such costs, in which case our operations 
could be adversely affected. 

In addition, the competitive environment for leasing is affected considerably by a number of factors including, among other 
things, changes due to economic factors such as supply and demand.  These factors may make it difficult for us to lease existing 
vacant space and space associated with future lease expirations at rental rates that are sufficient to meet our short-term capital 
needs.

We rely on the ability of our tenants to pay rent and would be harmed by their inability to do so.  Our performance 
depends on the ability of our tenants to fulfill their lease obligations by paying their rental payments in a timely manner.  As a 
result, we would be harmed if one or more of our major tenants, or a number of our smaller tenants, were to experience 
financial difficulties, including bankruptcy, insolvency, prolonged government shutdown or general downturn of business. 

We may be adversely affected by developments concerning our major tenants or the USG and its contractors, 

including prolonged shutdowns of the government and actual, or potential, reductions in government spending targeting 
knowledge- and technology-based activities.  As of December 31, 2020, our 10 largest tenants accounted for 62.7% of our 
total annualized rental revenue, the three largest of these tenants accounted for 48.8%, and the USG, our largest tenant, 
accounted for 34.1%.  We calculate annualized rental revenue by multiplying by 12 the sum of monthly contractual base rents 
and estimated monthly expense reimbursements under active leases in our portfolio as of December 31, 2020; with regard to 
properties owned through unconsolidated real estate joint ventures, we include the portion of annualized rental revenue 
allocable to our ownership interest.  For additional information regarding our tenant concentrations, refer to the section entitled 
“Concentration of Operations” within the section entitled “Management’s Discussion and Analysis of Financial Condition and 
Results of Operations.”

Most of our leases with the USG provide for a series of one-year terms.  The USG may terminate its leases if, among other 

reasons, the United States Congress fails to provide funding.  We would be harmed if any of our largest tenants fail to make 
rental payments to us over an extended period of time, including as a result of a prolonged government shutdown, or if the USG 
elects to terminate some or all of its leases and the space cannot be re-leased on satisfactory terms. 

As of December 31, 2020, 87.1% of our office and data center shell properties’ total annualized rental revenue was from 
Defense/IT Locations, and we expect to maintain a similarly high revenue concentration from properties in these locations.  A 
reduction in government spending targeting the activities of the government and its contractors (such as knowledge- and 
technology-based defense and security activities) in these locations could adversely affect our tenants’ ability to fulfill lease 
obligations, renew leases or enter into new leases and limit our future growth from properties in these locations.  Moreover, 
uncertainty regarding the potential for future reduction in government spending targeting such activities could also decrease or 
delay leasing activity from tenants engaged in these activities.

Our future ability to fuel growth and raise capital through data center shell development may be adversely affected 
should we suffer a loss of future development opportunities with our data center shell customer.  Data center shells have 
been a significant growth driver for us in recent years, enabling us to develop and place into service fully-occupied, single-
tenant properties, with long-term leases and rent escalators for future growth.  These properties have garnered the interest of 
outside investors, enabling us to raise capital by selling ownership interests through joint venture structures in recent years at 
favorable profit margins, and to apply the proceeds towards other development opportunities.  Our data center shell activity is 
concentrated with one customer.  If that customer no longer chooses to allocate development opportunities to us, we may have 
limited opportunities to continue to use data center shells as a growth driver and possible source of future capital.

We may suffer economic harm in the event of a decline in the real estate market or general economic conditions in 

the Mid-Atlantic region, particularly in the Greater Washington, DC/Baltimore region, or in particular business parks.  
Most of our properties are located in the Mid-Atlantic region of the United States, particularly in the Greater Washington, DC/
Baltimore region.  Our properties are also often concentrated in business parks in which we own most of the properties.  
Consequently, our portfolio of properties is not broadly distributed geographically.  As a result, we would be harmed by a 
decline in the real estate market or general economic conditions in the Mid-Atlantic region, the Greater Washington, DC/
Baltimore region or the business parks in which our properties are located. 

We would suffer economic harm if we were unable to renew our leases on favorable terms.  When leases expire, our 
tenants may not renew or may renew on terms less favorable to us than the terms of their original leases.  If a tenant vacates a 
property, we can expect to experience a vacancy for some period of time, as well as incur higher leasing costs than we would 
likely incur if a tenant renews.  As a result, we may be harmed if we experience a high volume of tenant departures at the end of 
their lease terms. 

We may be adversely affected by trends in the office real estate industry.  Businesses are increasingly permitting 
employee telecommuting, flexible work schedules, open workplaces and teleconferencing.  There has also been a trend of  
businesses utilizing shared office and co-working spaces.  These practices enable businesses to reduce their space requirements.  
These trends, some of which could potentially accelerate as a result of changes in work practices during the COVID-19 
pandemic, could over time erode the overall demand for office space and, in turn, place downward pressure on occupancy, 
rental rates and property valuations.

We may encounter a significant decline in the value of our real estate.  The value of our real estate could be adversely 

affected by general economic and market conditions connected to a specific property, a market or submarket, a broader 
economic region or the office real estate industry.  Examples of such conditions include a broader economic recession, 
declining demand and decreases in market rental rates and/or market values of real estate assets.  If our real estate assets 
significantly decline in value, it could result in our recognition of impairment losses.  Moreover, a decline in the value of our 
real estate could adversely affect the amount of borrowings available to us under future credit facilities and other loans.  

We may not be able to compete successfully with other entities that operate in our industry.  The commercial real 
estate market is highly competitive.  Numerous commercial properties compete with our properties for tenants; some of the 
properties competing with ours may be newer or in more desirable locations, or the competing properties’ owners may be 
willing to accept lower rates than are acceptable to us.  In addition, we compete for the acquisition of land and commercial 
properties with many entities, including other publicly traded commercial office REITs; competitors for such acquisitions may 
have substantially greater financial resources than ours, or may be willing to accept lower returns on their investments or incur 
higher leverage.

Real estate investments are illiquid, and we may not be able to dispose of properties on a timely basis when we 
determine it is appropriate to do so.  Real estate investments can be difficult to sell and convert to cash quickly, especially if 
market conditions, including real estate lending conditions, are not favorable.  Such illiquidity could limit our ability to fund 
capital needs or quickly change our portfolio of properties in response to changes in economic or other conditions.  Moreover, 
under certain circumstances, the Internal Revenue Code imposes penalties on a REIT that sells property held for less than two 
years and limits the number of properties it can sell in a given year. 

We may be unable to execute our plans to develop additional properties.  Although the majority of our investments are 

in operating properties, we also develop and redevelop properties, including some that are not fully pre-leased.  When we 
develop and redevelop properties, we assume the risk of actual costs exceeding our budgets, conditions occurring that delay or 
preclude project completion and projected leasing not occurring.  In addition, we may find that we are unable to successfully 
execute plans to obtain financing to fund property development activities.

We may suffer adverse effects from acquisitions of commercial real estate properties.  We may pursue acquisitions of 

existing commercial real estate properties as part of our property development and acquisition strategy.  Acquisitions of 
commercial properties entail risks, such as the risk that we may not be in a position, or have the opportunity in the future, to 
make suitable property acquisitions on advantageous terms and/or that such acquisitions fail to perform as expected.

We may pursue selective acquisitions of properties in regions where we have not previously owned properties.  These 
acquisitions may entail risks in addition to those we face with acquisitions in more familiar regions, such as our not sufficiently 
anticipating conditions or trends in a new market and therefore not being able to operate the acquired property profitably.

13

In addition, we may acquire properties that are subject to liabilities in situations where we have no recourse, or only limited 

recourse, against the prior owners or other third parties with respect to unknown liabilities.  As a result, if a liability were 
asserted against us based upon ownership of those properties, we might have to pay substantial sums to settle or contest it.  
Examples of unknown liabilities with respect to acquired properties include, but are not limited to: 

•
•
•
•

liabilities for remediation of disclosed or undisclosed environmental contamination;
claims by tenants, vendors or other persons dealing with the former owners of the properties;
liabilities incurred in the ordinary course of business; and
claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the 
properties.

Our wholesale data center may become obsolete.  Wholesale data centers are much more expensive investments on a per 

square foot basis than office properties due to the level of infrastructure required to operate the centers.  At the same time, 
technology, industry standards and service requirements for wholesale data centers are rapidly evolving and, as a result, the risk 
of investments we make in our wholesale data center becoming obsolete is higher than other commercial real estate properties.  
Our wholesale data center may become obsolete due to the development of new systems to deliver power to, or eliminate heat 
from, the servers housed in the properties, or due to other technological advances.  In addition, we may not be able to efficiently 
upgrade or change power and cooling systems to meet new demands or industry standards without incurring significant costs 
that we may not be able to pass on to our tenants.  

Data center space in certain of our office properties may be difficult to reposition for alternative uses.  Certain of our 

office properties contain data center space, which is highly specialized space containing extensive electrical and mechanical 
systems that are uniquely designed to run and maintain banks of computer servers.  Data centers are subject to obsolescence 
risks.  In the event that we needed to reposition such space for another use, the renovations required to do so could be difficult 
and costly, and we may, as a result, deem such renovations to be impractical.

We may be subject to possible environmental liabilities.  We are subject to various Federal, state and local 

environmental laws, including air and water quality, hazardous or toxic substances and health and safety.  These laws can 
impose liability on current and prior property owners or operators for the costs of removal or remediation of hazardous 
substances released on a property, even if the property owner was not responsible for, or even aware of, the release of the 
hazardous substances.  Costs resulting from environmental liability could be substantial.  The presence of hazardous substances 
on our properties may also adversely affect occupancy and our ability to sell or borrow against those properties.  In addition to 
the costs of government claims under environmental laws, private plaintiffs may bring claims for personal injury or other 
reasons.  Additionally, various laws impose liability for the costs of removal or remediation of hazardous substances at the 
disposal or treatment facility.  Anyone who arranges for the disposal or treatment of hazardous substances at such a facility is 
potentially liable under such laws. 

Although most of our properties have been subject to varying degrees of environmental assessment, many of these 
assessments are limited in scope and may not include or identify all potential environmental liabilities or risks associated with 
the property.  Identification of new compliance concerns or undiscovered areas of contamination, changes in the extent or 
known scope of contamination, discovery of additional sites, human exposure to the contamination or changes in cleanup or 
compliance requirements could result in significant costs to us.

We may be adversely affected by natural disasters and the effects of climate change.  Natural disasters, including 
earthquakes and severe storms could adversely impact our properties.  The potential consequences of climate change could also 
adversely impact our properties, particularly those located in Baltimore City near the waterfront, and, over time, could 
adversely affect demand for space and our ability to operate the properties effectively and result in additional operating costs. 

Terrorist attacks or incidents related to social unrest may adversely affect the value of our properties, our financial 

position and cash flows.  We have significant investments in properties located in large metropolitan areas or near military 
installations.  Future terrorist attacks or incidents related to social unrest could directly or indirectly damage our properties or 
cause losses that materially exceed our insurance coverage.  After such an attack or incident, tenants in these areas may choose 
to relocate their businesses to areas of the United States that may be perceived to be less likely targets of future terrorist activity 
or unrest, and fewer customers may choose to patronize businesses in these areas.  This in turn would trigger a decrease in the 
demand for space in these areas, which could increase vacancies in our properties and force us to lease space on less favorable 
terms. 

14

We may be subject to other possible liabilities that would adversely affect our financial position and cash flows.  Our 

properties may be subject to other risks related to current or future laws, including laws relating to zoning, development, fire 
and life safety requirements and other matters.  These laws may require significant property modifications in the future and 
could result in the levy of fines against us.  In addition, although we believe that we adequately insure our properties, we are 
subject to the risk that our insurance may not cover all of the costs to restore a property that is damaged by a fire or other 
catastrophic events, including acts of war or, as mentioned above, terrorism.

We may be subject to increased costs of insurance and limitations on coverage.  Our portfolio of properties is insured 
for losses under our property, casualty and umbrella insurance policies.  These policies include coverage for acts of terrorism.  
Future changes in the insurance industry’s risk assessment approach and pricing structure may increase the cost of insuring our 
properties and decrease the scope of insurance coverage.  Most of our loan agreements contain customary covenants requiring 
us to maintain insurance.  Although we believe that we have adequate insurance coverage for purposes of these agreements, we 
may not be able to obtain an equivalent amount of coverage at reasonable costs, or at all, in the future.  In addition, if lenders 
insist on greater coverage than we are able to obtain, it could adversely affect our ability to finance and/or refinance our 
properties and execute our growth strategies. 

We may suffer economic harm as a result of the actions of our partners in real estate joint ventures and other 

investments.  We may invest in certain entities in which we are not the exclusive investor or principal decision maker.  
Investments in such entities may, under certain circumstances, involve risks not present when a third party is not involved, 
including the possibility that the other parties to these investments might become bankrupt or fail to fund their share of required 
capital contributions.  Our partners in these entities may have economic, tax or other business interests or goals that are 
inconsistent with our business interests or goals, and may be in a position to take actions contrary to our policies or objectives.  
Such investments may also lead to impasses on major decisions, such as whether or not to sell a property, because neither we 
nor the other parties to these investments may have full control over the entity.  In addition, we may in certain circumstances be 
liable for the actions of the other parties to these investments.

Our business could be adversely affected by a negative audit by the USG.  Agencies of the USG, including the 

Defense Contract Audit Agency and various agency Inspectors General, routinely audit and investigate government contractors.  
These agencies review a contractor’s performance under its contracts, cost structure and compliance with applicable laws, 
regulations and standards.  The USG also reviews the adequacy of, and a contractor’s compliance with, its internal control 
systems and policies.  Any costs found to be misclassified may be subject to repayment.  If an audit or investigation uncovers 
improper or illegal activities, we may be subject to civil or criminal penalties and administrative sanctions, including 
termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business 
with the USG.  In addition, we could suffer serious reputational harm if allegations of impropriety were made against us. 

Risks Associated with Financing and Other Capital-Related Matters

We are dependent on external sources of capital for growth.  Because COPT is a REIT, it must distribute at least 90% 
of its annual taxable income to its shareholders.  Due to this requirement, we are not able to significantly fund our investment 
activities using retained cash flow from operations.  Therefore, our ability to fund these activities is dependent on our ability to 
access debt or equity capital.  Such capital could be in the form of new debt, common shares, preferred shares, common and 
preferred units in COPLP, joint venture funding or sales of interests in properties.  These capital sources may not be available 
on favorable terms or at all.  Moreover, additional debt financing may substantially increase our leverage and subject us to 
covenants that restrict management’s flexibility in directing our operations.  Our inability to obtain capital when needed could 
have a material adverse effect on our ability to expand our business and fund other cash requirements. 

We often use our Revolving Credit Facility to initially finance much of our investing activities and certain financing 

activities.  Our lenders under this and other facilities could, for financial hardship or other reasons, fail to honor their 
commitments to fund our requests for borrowings under these facilities.  If lenders default under these facilities by not being 
able or willing to fund a borrowing request, it would adversely affect our ability to access borrowing capacity under these 
facilities.

We may suffer adverse effects as a result of the indebtedness that we carry and the terms and covenants that relate 
to this debt.  Payments of principal and interest on our debt may leave us with insufficient cash to operate our properties or pay 

15

 
distributions to COPT’s shareholders required to maintain COPT’s qualification as a REIT.  We are also subject to the risks 
that: 

•

•

•

we may not be able to refinance our existing indebtedness, or may only be able to do so on terms that are less favorable to 
us than the terms of our existing indebtedness; 
in the event of our default under the terms of our Revolving Credit Facility, COPLP could be restricted from making cash 
distributions to COPT unless such distributions are required to maintain COPT’s qualification as a REIT, which could 
result in reduced distributions to our equityholders or the need for us to incur additional debt to fund such distributions; and
if we are unable to pay our debt service on time or are unable to comply with restrictive financial covenants for certain of 
our debt, our lenders could foreclose on our properties securing such debt and, in some cases, other properties and assets 
that we own.

Most of our unsecured debt is cross-defaulted, which means that failure to pay interest or principal on the debt above a 
threshold value will create a default on certain of our other debt.

If interest rates were to rise, our debt service payments on debt with variable interest rates would increase. 

As of December 31, 2020, we had $2.1 billion in debt, the future maturities of which are set forth in Note 10 to our 
consolidated financial statements.  Our operations likely will not generate enough cash flow to repay all of this debt without 
additional borrowings, equity issuances and/or property sales.  If we cannot refinance, extend the repayment date of, or 
otherwise raise funds required to repay, our debt by its maturity date, we would default on such debt. 

Our organizational documents do not limit the amount of indebtedness that we may incur.  Therefore, we may incur 

additional indebtedness and become more highly leveraged, which could harm our financial position. 

We may suffer adverse effects from changes in the method of determining LIBOR or the replacement of LIBOR 

with an alternative interest rate.  Our variable-rate debt and interest rate swaps use as a reference rate the London Interbank 
Offered Rate (“LIBOR”), as calculated for the U.S. dollar (“USD-LIBOR”).  In July 2017, the Financial Conduct Authority 
(“FCA”) that regulates LIBOR announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 
2021. As a result, the Federal Reserve Board and the Federal Reserve Bank of New York organized the Alternative Reference 
Rates Committee (“ARRC”), which identified the Secured Overnight Financing Rate (“SOFR”) as its preferred alternative rate 
for USD LIBOR in derivatives and other financial contracts.   While we have been closely monitoring developments in the 
LIBOR transition, we are not able to predict whether LIBOR will actually cease to be available after 2021 or whether SOFR 
will become the market benchmark in its place.  Any changes announced or adopted by the FCA or other governing bodies in 
the method used for determining LIBOR rates may result in a sudden or prolonged increase or decrease in reported LIBOR 
rates.  If that were to occur, the level of interest payments we incur may change.  In addition, although our variable rate debt 
and interest rate swaps will likely provide for alternative methods of calculating the interest rate if LIBOR is not reported, 
uncertainty as to the extent and manner of future changes may result in interest rates and/or payments that are higher or lower 
than if the LIBOR rate were to remain available in its current form.

A downgrade in our credit ratings would materially adversely affect our business and financial condition.  COPLP’s 

Senior Notes are currently rated investment grade by the three major rating agencies.  These credit ratings are subject to 
ongoing evaluation by the credit rating agencies and can change.  Any downgrades of our ratings or a negative outlook by the 
credit rating agencies would have a materially adverse impact on our cost and availability of capital and also could have a 
materially adverse effect on the market price of COPT’s common shares.  In addition, since the variable interest rate spread and 
facility fees on certain of our debt, including our Revolving Credit Facility and a term loan facility, is determined based on our 
credit ratings, a downgrade in our credit ratings would increase the payments required on such debt.

We have certain distribution requirements that reduce cash available for other business purposes.  Since COPT is a 

REIT, it must distribute at least 90% of its annual taxable income, which limits the amount of cash that can be retained for other 
business purposes, including amounts to fund development activities and acquisitions.  Also, due to the difference in time 
between when we receive revenue or pay expenses and when we report such items for distribution purposes, it is possible that 
we may need to borrow funds for COPT to meet the 90% distribution requirement.  

We may issue additional common or preferred shares/units that dilute our equityholders’ interests.  We may issue 
additional common and preferred shares/units without shareholder approval.  Similarly, COPT may cause COPLP to issue its 

16

common or preferred units for contributions of cash or property without approval by the limited partners of COPLP or COPT’s 
shareholders.  Our existing equityholders’ interests could be diluted if such additional issuances were to occur.

A number of factors could cause our security prices to decline.  As is the case with any publicly-traded securities, 
certain factors outside of our control could influence the value of our equity security issuances.  These conditions include, but 
are not limited to: 

• market perception of REITs in general and office REITs in particular;
• market perception regarding our major tenants and sector concentrations; 
•
•
•
•
•
• market perception of our financial condition, performance, dividends and growth potential; and
•

the level of institutional investor interest in COPT; 
general economic and business conditions; 
prevailing interest rates;
our financial performance;
our underlying asset value;

adverse changes in tax laws. 

We may be unable to continue to make distributions to our equityholders at expected levels.  We expect to make 
regular quarterly cash distributions to our equityholders.  However, our ability to make such distributions depends on a number 
of factors, some of which are beyond our control.  Some of our loan agreements contain provisions that could, in the event of 
default, restrict future distributions unless we meet certain financial tests or such payments or distributions are required to 
maintain COPT’s qualification as a REIT.  Our ability to make distributions at expected levels is also dependent, in part, on 
other matters, including, but not limited to: 

•
•
•
•
•
•

•
•
•
•

continued property occupancy and timely receipt of rent from our tenants; 
the amount of future capital expenditures and expenses relating to our properties; 
our leasing activity and future rental rates; 
the strength of the commercial real estate market; 
our ability to compete; 
governmental actions and initiatives, including risks associated with the impact of a prolonged government shutdown or 
budgetary reductions or impasses;
our costs of compliance with environmental and other laws; 
our corporate overhead levels; 
our amount of uninsured losses; and 
our decision to reinvest in operations rather than distribute available cash. 

In addition, we can make distributions to the holders of our common shares/units only after we make preferential distributions 
to holders of any outstanding preferred shares/units. 

Our ability to pay distributions may be limited, and we cannot provide assurance that we will be able to pay 
distributions regularly.  Our ability to pay distributions will depend on a number of things discussed elsewhere herein, 
including our ability to operate profitably and generate cash flow from our operations.  We cannot guarantee that we will be 
able to pay distributions on a regular quarterly basis in the future.  Additionally, the terms of some of COPLP’s debt may limit 
its ability to make some types of payments and other distributions to COPT in the event of certain default situations.  This in 
turn may limit our ability to make some types of payments, including payment of distributions on common or preferred shares/
units, unless we meet certain financial tests or such payments or distributions are required to maintain COPT’s qualification as a 
REIT.  As a result, if we are unable to meet the applicable financial tests, we may not be able to pay distributions in one or more 
periods.  Furthermore, any new common or preferred shares/units that may be issued in the future for raising capital, financing 
acquisitions, share-based compensation arrangements or otherwise will increase the cash required to continue to pay cash 
distributions at current levels. 

We may experience significant losses and harm to our financial condition if financial institutions holding our cash 
and cash equivalents file for bankruptcy protection.  We believe that we maintain our cash and cash equivalents with high 
quality financial institutions.  We have not experienced any losses to date on our deposited cash.  However, we may incur 
significant losses and harm to our financial condition in the future if we were holding large sums of cash in any of these 
financial institutions at a time when they filed for bankruptcy protection.

17

Risks Associated with COVID-19

We may suffer further adverse effects from the COVID-19 pandemic, and similar pandemics, along with restrictive 

measures instituted to prevent spread.  Since first being declared a pandemic by the World Health Organization in early 
March 2020, the coronavirus, or COVID-19, has spread worldwide.  In an effort to control its spread, governments and other 
authorities imposed restrictive measures affecting freedom of movement and business operations, such as shelter-in-place 
orders and business closures.  Strong restrictive measures were put into place in much of the United States beginning in March 
2020, bringing many businesses to a halt while forcing others to change the way in which they conduct their operations, with 
much of the workforce working from their homes to the extent they were able.  States and local governments began easing these 
measures to varying extents in late April 2020, with some lifting restrictive measures entirely, while others chose a more 
gradual, extended easing approach.  While the easing of these measures enabled many businesses to gradually resume normal 
operations, most businesses continue to be hindered to varying extents by either measures still in effect, operational challenges 
resulting from social distancing requirements/expectations and/or a reluctance by much of the population to engage in certain 
activities while the pandemic is still active.  As of the date of this filing, COVID-19 spread continues world- and nation-wide, 
and is expected to continue until vaccinations have been administered to much of the population, which is not expected to occur 
in the United States until at least mid- to late 2021.  As a result, there continues to be significant uncertainty regarding the 
duration and extent of this pandemic.  The outbreak significantly disrupted financial and economic markets worldwide, as well 
as in the United States at a national, regional and local level.  These conditions could continue or further deteriorate as 
businesses feel the prolonged effects of stalled or reduced operations and uncertainty regarding the pandemic continues.

COVID-19, and any similar pandemics should they occur, along with measures instituted to prevent spread, may adversely 

affect us in many ways, including, but not limited to:

•

•

•

•

•

•

disruption of our tenants’ operations, which could adversely affect their ability, or willingness, to sustain their businesses 
and/or fulfill their lease obligations;
our ability to maintain occupancy in our properties and obtain new leases for unoccupied and new development space at 
favorable terms or at all;
shortages in supply of products or services from our and our tenants’ vendors that are needed for us and our tenants to 
operate effectively, and which could lead to increased costs for such products and services;
access to debt and equity capital on attractive terms or at all.  Severe disruption and instability in the global financial 
markets or deteriorations in credit and financing conditions may affect our or our tenants’ ability to access capital necessary 
to fund operations, refinance debt or fund planned investments on a timely basis, and may adversely affect the valuation of 
financial assets and liabilities;
our and our tenants’ ability to continue or complete planned development, including the potential for delays in the supply 
of materials or labor necessary for development; and
an increase in the pace of businesses implementing remote work arrangements over the long-term, which would adversely 
effect demand for office space.

The extent of the effect on our operations, financial condition, cash flows and ability to make expected distributions to 
shareholders will be dependent on future developments, including the duration of the pandemic and any future resurgence or 
variants thereof, the prevalence, strength and duration of restrictive measures and the resulting effects on our tenants, potential 
future tenants, the commercial real estate industry and the broader economy, all of which are uncertain and difficult to predict.  
Moreover, some of the risks described in other risk factors set forth in this Annual Report on Form 10-K may be more likely to 
impact us as a result of COVID-19 and the responses to curb its spread, including, but not limited to: downturns in national, 
regional and local economic environments; deteriorating local real estate market conditions; and declining real estate 
valuations.

Other Risks

Our business could be adversely affected by security breaches through cyber attacks, cyber intrusions or otherwise.  

We face risks associated with security breaches and other significant disruptions of our information technology networks and 
related systems, which are essential to our business operations.  Such breaches and disruptions may occur 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.  Because of our concentration on serving the USG and its contractors 
with a general focus on national security and information technology, we may be more likely to be targeted by cyber attacks, 
including by governments, organizations or persons hostile to the USG.  We have preventative, detective and responsive 
measures in place to maintain the security and integrity of our networks and related systems that have to date enabled us to 

18

avoid breaches and disruptions that were individually, or in the aggregate, material.  We also have insurance coverage in place 
in the event of significant future losses from breaches and disruptions.  However, despite our activities to maintain the security 
and integrity of our networks and related systems, there can be no absolute assurance that these activities will be effective in 
mitigating these risks.  A security breach involving our networks and related systems could disrupt our operations in numerous 
ways, including compromising the confidential information of our tenants, customers, vendors and employees, which could 
damage our relationships with such parties, and disrupting the proper functioning of our networks and systems on which much 
of our operations depend.

COPT’s ownership limits are important factors.  COPT’s Declaration of Trust limits ownership of its common shares 

by any single shareholder to 9.8% of the number of the outstanding common shares or 9.8% of the value of the outstanding 
common shares, whichever is more restrictive.  COPT’s Declaration of Trust also limits ownership by any single shareholder of 
our common and preferred shares in the aggregate to 9.8% of the aggregate value of our outstanding common and preferred 
shares.  We call these restrictions the “Ownership Limit.”  COPT’s Declaration of Trust allows our Board of Trustees to exempt 
shareholders from the Ownership Limit.  The Ownership Limit and the restrictions on ownership of our common shares may 
delay or prevent a transaction or a change of control that might involve a premium price for our common shares/units or 
otherwise be in the best interest of our equityholders.

COPT’s Declaration of Trust includes other provisions that may prevent or delay a change of control.  Subject to the 
requirements of the New York Stock Exchange, our Board of Trustees has the authority, without shareholder approval, to issue 
additional securities on terms that could delay or prevent a change in control.  In addition, our Board of Trustees has the 
authority to reclassify any of our unissued common shares into preferred shares.  Our Board of Trustees may issue preferred 
shares with such preferences, rights, powers and restrictions as our Board of Trustees may determine, which could also delay or 
prevent a change in control. 

The Maryland business statutes impose potential restrictions that may discourage a change of control of our 
company.  Various Maryland laws may have the effect of discouraging offers to acquire us, even if the acquisition would be 
advantageous to equityholders.  Resolutions adopted by our Board of Trustees and/or provisions of our bylaws exempt us from 
such laws, but our Board of Trustees can alter its resolutions or change our bylaws at any time to make these provisions 
applicable to us. 

COPT’s failure to qualify as a REIT would have adverse tax consequences, which would substantially reduce funds 
available to make distributions to our equityholders.  We believe that COPT has qualified for taxation as a REIT for Federal 
income tax purposes since 1992.  We plan for COPT to continue to meet the requirements for taxation as a REIT.  Many of 
these requirements, however, are highly technical and complex.  The determination that we are a REIT requires an analysis of 
various factual matters and circumstances that may not be totally within our control.  For example, to qualify as a REIT, at least 
95% of COPT’s gross income must come from certain sources that are specified in the REIT tax laws.  COPT is also required to 
distribute to shareholders at least 90% of its annual taxable income.  The fact that COPT holds most of its assets through 
COPLP and its subsidiaries further complicates the application of the REIT requirements.  Even a technical or inadvertent 
mistake could jeopardize COPT’s REIT status.  Furthermore, Congress and the Internal Revenue Service might make changes 
to the tax laws and regulations and the courts might issue new rulings that make it more difficult or impossible for COPT to 
remain qualified as a REIT. 

If COPT fails to qualify as a REIT, it would be subject to Federal income tax at regular corporate rates.  Also, unless the 
Internal Revenue Service granted us relief under certain statutory provisions, COPT would remain disqualified as a REIT for 
four years following the year it first fails to qualify.  If COPT fails to qualify as a REIT, it would have to pay significant income 
taxes and would therefore have less money available for investments or for distributions to our equityholders.  In addition, if 
COPT fails to qualify as a REIT, it would no longer be required to pay distributions to shareholders.  As a result of all these 
factors, COPT’s failure to qualify as a REIT could impair our ability to expand our business and raise capital and would likely 
have a significant adverse effect on the value of our shares/units. 

We may be adversely impacted by changes in tax laws.  At any time, U.S. federal tax laws or the administrative 
interpretations of those laws may be changed.  We cannot predict whether, when or to what extent new U.S. federal tax laws, 
regulations, interpretations or rulings will be issued.  In addition, while REITs generally receive certain tax advantages 
compared to entities taxed as C corporations, it is possible that future legislation could result in REITs having fewer tax 
advantages, and therefore becoming a less attractive investment alternative.  As a result, changes in U.S. federal tax laws could 
negatively impact our operating results, financial condition and business operations, and adversely impact our equityholders.

19

Occasionally, changes in state and local tax laws or regulations are enacted that may result in an increase in our tax 

liability.  Shortfalls in tax revenues for states and municipalities may lead to an increase in the frequency and size of such 
changes.  If such changes occur, we may be required to pay additional taxes on our assets, revenue or income.

Our tenants and contractual counterparties could be designated “Prohibited Persons” by the Office of Foreign 
Assets Control.  The Office of Foreign Assets Control of the United States Department of the Treasury (“OFAC”) maintains a 
list of persons designated as terrorists or who are otherwise blocked or banned (“Prohibited Persons”).  OFAC regulations and 
other laws prohibit us from conducting business or engaging in transactions with Prohibited Persons.  If a tenant or other party 
with whom we conduct business is placed on the OFAC list or is otherwise a party with whom we are prohibited from doing 
business, we would be required to terminate the lease or other agreement.

(1) This percentage is based upon all rentable square feet or megawatts under lease terms that were in effect as of December 31, 2020. 
(2) Annualized rental revenue is the monthly contractual base rent as of December 31, 2020 (ignoring free rent then in effect) 

multiplied by 12, plus the estimated annualized expense reimbursements under existing leases.  With regard to properties owned 
through unconsolidated real estate joint ventures, we include the portion of annualized rental revenue allocable to our ownership 
interest.  We consider annualized rental revenue to be a useful measure for analyzing revenue sources because, since it is point-in-
time based, it does not contain increases and decreases in revenue associated with periods in which lease terms were not in effect; 
historical revenue under generally accepted accounting principles does contain such fluctuations. We find the measure particularly 
useful for leasing, tenant and segment analysis. 

(3) Annualized rental revenue per occupied square foot is a property’s annualized rental revenue divided by that property’s occupied 
square feet as of December 31, 2020.  Our computation of annualized rental revenue excludes the effect of lease incentives.  The 
annualized rent per occupied square foot, including the effect of lease incentives, was $31.11 for our total office and data center 
shell portfolio, $33.66 for the Fort Meade/BW Corridor (our largest Defense/IT Location sub-segment) and $34.85 for our Regional 
Office portfolio.

(4) Represents properties owned through unconsolidated real estate joint ventures.  The amounts reported above reflect 100% of the 
properties’ square footage but only reflect the portion of Annualized Rental Revenue that was allocable to our ownership interest.

Item 5.  Market for Registrants’ Common Equity, Related Stockholder Matters and Issuer Purchases of Equity 
Securities

COPT’s common shares trade on the New York Stock Exchange (“NYSE”) under the symbol “OFC.”  The number of 
holders of record of COPT’s common shares was 462 as of January 22, 2021.  This number does not include shareholders 
whose shares were held of record by a brokerage house or clearing agency, but does include any such brokerage house or 
clearing agency as one record holder. 

There is no established public trading market for COPLP’s partnership units.  Quarterly common unit distributions per unit 

were the same as quarterly common dividends per share declared by COPT.  As of January 22, 2021, there were 28 holders of 
record of COPLP’s common units.

Unregistered Sales of Equity Securities and Use of Proceeds

During the three months ended December 31, 2020, COPT issued 2,000 common shares in exchange for 2,000 COPLP 

common units in accordance with COPLP’s Third Amended and Restated Limited Partnership Agreement, as amended.  The 
issuance of these common shares was effected in reliance upon the exemption from registration under Section 4(a)(2) of the

Item 7.  Management's Discussion and Analysis of Financial Condition and Results of Operations

You should refer to our consolidated financial statements and the notes thereto and our Selected Financial Data table as you 

read this section.

This section contains “forward-looking” statements, as defined in the Private Securities Litigation Reform Act of 1995, that 

are based on our current expectations, estimates and projections about future events and financial trends affecting the financial 
condition and operations of our business.  Forward-looking statements can be identified by the use of words such as “may,” 
“will,” “should,” “could,” “believe,” “anticipate,” “expect,” “estimate,” “plan” or other comparable terminology.  Forward-
looking statements are inherently subject to risks and uncertainties, many of which we cannot predict with accuracy and some 
of which we might not even anticipate.  Although we believe that the expectations, estimates and projections reflected in such 
forward-looking statements are based on reasonable assumptions at the time made, we can give no assurance that these 
expectations, estimates and projections will be achieved.  Future events and actual results may differ materially from those 
discussed in the forward-looking statements.  Important factors that may affect these expectations, estimates and projections 
include, but are not limited to:

•

•
•

•

•
•

•

•

•

•
•
•
•
•

general economic and business conditions, which will, among other things, affect office property and data center demand 
and rents, tenant creditworthiness, interest rates, financing availability and property values; 
adverse changes in the real estate markets, including, among other things, increased competition with other companies;
risks and uncertainties regarding the impact of the COVID-19 pandemic, and similar pandemics, along with restrictive 
measures instituted to prevent spread, on our business, the real estate industry and national, regional and local economic 
conditions; 
governmental actions and initiatives, including risks associated with the impact of a prolonged government shutdown or 
budgetary reductions or impasses, such as a reduction in rental revenues, non-renewal of leases and/or reduced or delayed 
demand for additional space by our strategic customers;
our ability to borrow on favorable terms; 
risks of real estate acquisition and development activities, including, among other things, risks that development projects 
may not be completed on schedule, that tenants may not take occupancy or pay rent or that development or operating costs 
may be greater than anticipated;
risks of investing through joint venture structures, including risks that our joint venture partners may not fulfill their 
financial obligations as investors or may take actions that are inconsistent with our objectives;
changes in our plans for properties or views of market economic conditions or failure to obtain development rights, either 
of which could result in recognition of significant impairment losses;
our ability to satisfy and operate effectively under Federal income tax rules relating to real estate investment trusts and 
partnerships;
possible adverse changes in tax laws;
the dilutive effects of issuing additional common shares;
our ability to achieve projected results;
security breaches relating to cyber attacks, cyber intrusions or other factors; and
environmental requirements. 

We undertake no obligation to publicly update or supplement forward-looking statements.

Overview

While 2020 will most likely be remembered for the COVID-19 pandemic, including the restrictive measures instituted to 

prevent spread and the resulting economic uncertainty, we do not believe that the pandemic significantly affected our ability to 
execute our business strategy due primarily to our portfolio’s significant concentration in Defense/IT Locations.  The tenants in 
most of these properties were designated as “essential businesses,” and therefore exempt from use and occupancy restrictions 
that otherwise affected much of the commercial real estate industry.  Furthermore, since the tenants in these properties 
continued to be compensated by the USG for their services, we believe that their ability, and willingness, to fulfill their lease 
obligations was not significantly disrupted.  As a result, while COVID-19 affected the manner in which we conducted our 
operations and adversely impacted certain of our other tenants and property types, we do not believe that it significantly 
affected our financial condition, results of operations and cash flows in 2020.  Please refer to the section below entitled “Effects 
of COVID-19” for additional related disclosure.

27

 
 
We ended 2020 with higher leased and occupancy percentages for our office and data center shell portfolio both portfolio-

wide and for our Same Properties and, notably, our highest year end portfolio-wide occupancy since 2001.  We ended 2020 
with our office and data center shell portfolio 94.8% leased (compared to 94.4% as of December 31, 2019) while our Same 
Properties were 93.1% leased (compared to 93.0% as of December 31, 2019).  Our year end portfolio-wide office and data 
center shell occupancy was 94.1% (compared to 92.9% as of December 31, 2019) and Same Properties occupancy was 92.1% 
(compared to 91.1% as of December 31, 2019).  Our wholesale data center was 86.7% leased as of year end (compared to 
76.9% as of December 31, 2019).   Please refer to the section below entitled “Occupancy and Leasing” for additional related 
disclosure. 

The higher occupancy and leased percentages in our office and data center shell portfolio were attributable primarily to our 

placing into service an annual record 1.8 million square feet in 11 newly-developed properties, expansions of three fully-
operational properties and one redeveloped property that were 99.5% leased as of December 31, 2020.  These properties were 
predominantly Defense/IT Locations in our data center shells or Redstone Arsenal sub-segments.  Other noteworthy 2020 
leasing activity in our operating portfolio included:

•

•

renewal leasing of 2.2 million square feet, resulting in a portfolio-wide tenant retention rate of 80.6% (81.6% for our 
Defense/IT Locations), one of our highest annual rates on record.  This leasing included the effect of large early renewals 
of leases previously scheduled to expire in 2021.  Strong tenant retention is key to our asset management strategy in order 
to maximize revenue (by avoiding downtime) and minimize leasing capital; and
vacant space leasing of 416,000 square feet, which fell short of our beginning of 2020 expectations due to the impact of 
restrictive measures and the economic uncertainty caused by the pandemic.  

As of December 31, 2020, our scheduled lease expirations in 2021, representing 7.5% of our total occupied square feet, 
included a high concentration of space in what we believe to be mission-critical Defense/IT Locations.  This space included 
only two leases of 100,000 square feet or more that are with the USG and expected to be renewed.  

We had 1.0 million square feet of development leasing in 2020, representing our fourth highest annual volume.  Nearly half 

of this leasing was for data center shells, and we also leased new property space in four of our five other Defense/IT Locations 
sub-segments.  We ended the year with 1.5 million square feet in properties under development that were 84% leased in 
aggregate, which included new properties in each of our named office and data center shell segments and sub-segments.  Most 
of these properties were 100% leased and all but one were more than half leased (the one being a property built on a speculative 
basis in Redstone Arsenal in order to keep pace with what we believe to be very strong demand, illustrated by that sub-
segment’s 99.4% year-end occupancy rate).  For further disclosure regarding our development underway as of year end, please 
refer to Item 2 of this Annual Report on Form 10-K.

We believe that our 2020 leasing greatly benefited from a continued:

healthy defense spending environment, with bipartisan support for funding our national defense.  We believe that 
successive increases in defense spending since 2016, including, most recently, in the National Defense Authorization Act 
for Fiscal Year 2021, have enhanced the USG and defense contractor tenants’ ability to invest in facility planning.  This 
environment has helped fuel leasing demand, as has continued prioritization of spending allocations towards technology 
and innovation programs benefiting our Defense/IT Locations, including cyber, space, unmanned systems and artificial 
intelligence; and
demand for data center shells.  Our leasing included two new data center shells in Northern Virginia, the largest data center 
market in the world, and represented further expansion of our relationship with an existing customer.  As of year end, we 
held land that would accommodate an additional 1.2 million square feet in future data center shell development.

With respect to financing activities, we: 

amended an existing term loan facility to increase the loan amount by $150.0 million and reduce the LIBOR interest rate 
spread on the facility.  We used the resulting loan proceeds to repay borrowings under our Revolving Credit Facility that 
funded development costs;
refinanced unsecured senior notes due to mature in June 2021 with a new note issuance on September 17, 2020 by:
•

issuing $400.0 million of 2.25% Notes at an initial offering price of 99.416% of their face value.  The proceeds from 
this issuance, after deducting underwriting discounts but before other offering expenses, were approximately 
$395.3 million; and
purchased or redeemed $300.0 million of 3.70% Notes for $306.9 million plus accrued interest.

•

28

We used the remaining proceeds from the 2.25% Notes issuance to repay borrowings under our Revolving Credit Facility 
and for general corporate purposes, which included the cash settlement of three forward-starting interest rate swaps and 
accrued interest thereon for $53.1 million;
raised equity by selling interests in single tenant data center shells in Northern Virginia, including proceeds of 
approximately:
•

$81 million on October 30, 2020 from our sale of a 90% interest in two data center shell properties based on an 
aggregate property value of $89.7 million.  We retained a 10% interest in the properties through B RE COPT DC JV II 
LLC  (“B RE COPT”), a newly-formed joint venture.  We recognized a gain on sale of $30.0 million; and
$60 million on December 22, 2020 from our sale, through a series of transactions, of 80% of our 50% interests in 
LLCs holding six properties and associated mortgage debt that we owned through GI-COPT DC Partnership LLC, an 
unconsolidated joint venture.  We retained a 10% interest in the LLCs through B RE COPT, and recognized a gain of 
$29.4 million on the sale of interests. 

•

We used most of these sale proceeds to repay borrowings under our Revolving Credit Facility; and
redeemed COPLP’s Series I Preferred Units from the third party unitholder at the units’ aggregate liquidation preference of 
$8.8 million ($25.00 per unit), plus accrued and unpaid distributions of return thereon up to the date of redemption.

•

•

These activities enabled us to fund $344.4 million in development costs in 2020, while ending the year with: no debt maturing 
in 2021; no remaining preferred equity; and $657.0 million in borrowing capacity available to us under our Revolving Credit 
Facility. 

Net income in 2020 was $97.1 million lower than in 2019 due primarily to a: $53.2 million loss on interest rate derivatives 

in 2020 recognized when we consummated the 2.25% Notes issuance; and $45.6 million decrease in gains from sales of real 
estate interests due to lower sales volume in 2020.  Net operating income (“NOI”) from real estate operations, our segment 
performance measure discussed further below, increased $6.8 million from 2019 to 2020, due primarily to: a $20.5 million 
increase from properties newly placed into service; offset in part by a net decrease of $9.7 million from dispositions due to our 
sales of property interests in 2019 and 2020.  NOI from our Same Properties only changed marginally, increasing $0.8 million, 
or 0.3%.  Additional disclosure comparing our 2020 and 2019 results of operations is provided below. 

We discuss significant factors contributing to changes in our net income between 2020 and 2019 in the section below 
entitled “Results of Operations.”  The results of operations discussion is combined for COPT and COPLP because there are no 
material differences in the results of operations between the two reporting entities.

In addition, the section below entitled “Liquidity and Capital Resources” includes discussions of, among other things:

•
•

how we expect to generate cash for short and long-term capital needs; and
our commitments and contingencies.

We refer to the measure “annualized rental revenue” in various sections of the Management’s Discussion and Analysis of 

Financial Condition and Results of Operations section of this Annual Report on Form 10-K.  Annualized rental revenue is a 
measure that we use to evaluate the source of our rental revenue as of a point in time.  It is computed by multiplying by 12 the 
sum of monthly contractual base rents and estimated monthly expense reimbursements under active leases as of a point in time 
(ignoring free rent then in effect).  Our computation of annualized rental revenue excludes the effect of lease incentives, 
although the effect of this exclusion is not material.  We consider annualized rental revenue to be a useful measure for 
analyzing revenue sources because, since it is point-in-time based, it does not contain increases and decreases in revenue 
associated with periods in which lease terms were not in effect; historical revenue under generally accepted accounting 
principles in the United States of America (“GAAP”) does contain such fluctuations.  We find the measure particularly useful 
for leasing, tenant, segment and industry analysis.  

With regard to our operating portfolio square footage, occupancy and leasing statistics included below and elsewhere in 

this Annual Report on Form 10-K, amounts disclosed include total information pertaining to properties owned through 
unconsolidated real estate joint ventures except for amounts reported for annualized rental revenue, which represent the portion 
attributable to our ownership interest.

Effects of COVID-19

Pandemic Overview

Since first being declared a pandemic by the World Health Organization in early March 2020, the coronavirus, or 
COVID-19, has spread worldwide.  In an effort to control its spread, governments and other authorities imposed restrictive 
measures affecting freedom of movement and business operations, such as shelter-in-place orders and business closures.  Strong 
restrictive measures were put into place in much of the United States beginning in March 2020, bringing many businesses to a 
halt while forcing others to change the way in which they conduct their operations, with much of the workforce working from 
their homes to the extent they were able.  States and local governments began easing these measures to varying extents in late 
April 2020, with some lifting restrictive measures entirely, while others chose a more gradual, extended easing approach.  
While the easing of these measures enabled many businesses to gradually resume normal operations, most businesses continue 
to be hindered to varying extents by either measures still in effect, operational challenges resulting from social distancing 
requirements/expectations and/or a reluctance by much of the population to engage in certain activities while the pandemic is 
still active.  As of the date of this filing, COVID-19 spread continues world- and nation-wide, and is expected to continue until 
vaccinations have been administered to much of the population, which is not expected to occur in the United States until at least 
mid- to late 2021.  As a result, there continues to be significant uncertainty regarding the duration and extent of this pandemic.  
The outbreak has significantly disrupted financial and economic markets worldwide, as well as in the United States at a 
national, regional and local level.  These conditions could continue or further deteriorate as businesses feel the prolonged 
effects of stalled or reduced operations and uncertainty regarding the pandemic continues.

Effect on Real Estate Industry

COVID-19 has significantly affected the operations of much of the commercial real estate industry as certain tenants’ 
operations, including the ability to use space and run businesses, have been disrupted.  This has adversely affected tenants’ 
ability to sustain their businesses, including their ability, or willingness, to fulfill their lease obligations.  The industry has also 
been significantly impacted by the economic disruption that COVID-19 has triggered, which has affected the ability to lease 
space in many property types to new and existing tenants at favorable terms.  Key demand drivers for office space, such as 
employment levels, business confidence and corporate profits, have been adversely affected.  In addition, after months of 
businesses operating in significant part through remote work arrangements out of necessity, the pace of such arrangements 
becoming more prevalent long-term could accelerate, adversely affecting office space demand, although that effect may be 
offset by a slowing in the trend toward adoption of shared office and open workplace structures due to greater social distancing 
concerns.  As a result, the commercial real estate industry, including office real estate, has suffered adverse impacts in its 
operations, financial conditions and cash flows due to the COVID-19 pandemic and faces the potential for future effects.

Effect on the Company

Our office and data center shell portfolio is significantly concentrated in Defense/IT Locations, representing 171 of the 
portfolio’s 181 properties, or 87.1% of our annualized rental revenue as of December 31, 2020.  These properties are primarily 
occupied by the USG and contractor tenants engaged in what we believe are high-priority security, defense and IT missions.  As 
a result, most of these properties were designated as “essential businesses,” and therefore exempt from many of the restrictions 
that otherwise have affected much of the commercial real estate industry.  Furthermore, since the tenants in these properties are 
mostly the USG, or contractors of the USG who continue to be compensated by the USG for their services, we believe that their 
ability, and willingness, to fulfill their lease obligations have not been disrupted.  Our Defense/IT Locations do include tenants 
serving as amenities to business parks housing our properties (such as restaurant, retail and personal service providers); while 
these tenants’ operations have been significantly disrupted by COVID-19, our annualized rental revenue from these tenants is 
not significant.

As of December 31, 2020, we owned eight Regional Office properties, representing 12.5% of our office and data center 

shell portfolio’s annualized rental revenue.  These properties were comprised of: three high-rise Baltimore City properties 
proximate to the city’s waterfront; four Northern Virginia properties; and a newly-developed property in Washington, D.C.’s 
central business district.  While these properties include tenants in the financial services, health care and public health sectors, 
which, as “essential businesses,” have been exempt from restrictions on operations, they also include a number of non-essential 
business tenants.  These properties are more subject to traditional office fundamentals than our Defense/IT Locations and 
therefore face much of the enhanced risk in adverse impacts from COVID-19 described above.

The pandemic has affected the manner in which we conduct our operations in the following ways:

for the operations of our properties:
•
•
•

we consulted with medical experts in developing an approach to safely operate our properties during the pandemic;
we use manufacturer recommended heating and air conditioning filters to ensure appropriate outside air distribution;
we proactively engaged our tenants to help them through unknowns as pandemic concerns heightened and restrictive 
measures were being instituted, and maintained that engagement to ensure communication regarding steps we were 
taking in our business operations, any changes in tenant operations (such as office closures or revised work schedules) 
and the existence of any actual or presumed COVID-19 cases in properties;
our on-site property operations staff have been required to use personal protective equipment, such as masks, gloves 
and hand sanitizer, and implement other procedural changes to enhance separation and minimize spread;
we instituted enhanced cleaning measures, particularly for high touch areas and flat surfaces, and conducted special 
deep cleanings in properties potentially affected by actual or presumed COVID-19 cases;
we provided signage promoting proper social distancing practices and hand sanitizer stations for property common 
area lobbies; and
for properties that were not being used by tenants due to office closures or work from home arrangements, we locked 
down public (non-tenant) access to the properties for security purposes and instituted other measures aimed at 
managing costs;

for our employees:
•

our staff deemed to be essential, including our executives, select other members of our leadership team and most of our 
property management team, have continued to report to their normal work locations; and

• most of our other staff worked from home from mid-March until the end of May, when most began reporting to their 

normal work locations on a bi-weekly rotational basis; and

for our leasing activities:
•
•

we continued active engagement for lease transactions already in progress while business closures were in place; 
during periods of time in which we were unable to physically show space to prospective tenants (from mid-March until 
late May to mid-June), we showed space to new prospective tenants using a combination of virtual technology and pre-
recorded video tours; and
we implemented new advertising strategies to promote space availability.

•

•

•

•

•

As of the date of this filing, we believe that COVID-19 has not significantly affected our results of operations.  Our:

same property NOI from real estate operations increased 0.3% for the year ended December 31, 2020 relative to 2019.  
Included in this increase were offsets associated with a $2.8 million increase in provisions for collectability losses and a 
$1.9 million decrease in parking revenue for the year ended December 31, 2020 relative to 2019.  Substantially all of the 
increase in collectability losses was attributable to tenants whose operations were significantly disrupted by the pandemic 
(including primarily tenants serving as amenities to Defense/IT Location properties);
other lease revenue collections were not significantly affected by the pandemic.  However, we have agreed to deferred 
payment arrangements for approximately $2.6 million in lease receivables to be repaid in most cases by 2021 with 
primarily Regional Office tenants and tenants serving as amenities to Defense/IT Location properties whose operations 
were significantly disrupted;
office and data center shell portfolio was 94.1% occupied (compared to 92.9% at December 31, 2019) and 94.8% leased 
(compared to 94.4% at December 31, 2019) and our Same Properties portfolio was 92.1% occupied (compared to 91.1% at 
December 31, 2019) and 93.1% leased (compared to 93.0% at December 31, 2019);
operating expenses included the effect of higher cleaning and maintenance related costs, which were partially offset by 
higher tenant expense reimbursements; and 
leadership team concluded that the economic disruption resulting from COVID-19 constituted a significant adverse change 
in the business climate that could affect the value of our Regional Office properties, which are dependent on commercial 
office tenants and could suffer increased vacancy as a result.  Accordingly, we concluded that these circumstances 
constituted an indicator of impairment.  We performed recovery analyses for each Regional Office property’s asset group 
and concluded that the carrying value of each asset group was recoverable from the respective estimated undiscounted 
future cash flows.  As a result, no impairment loss was recognized.

While we do not currently expect that COVID-19 will significantly affect our future results of operations, financial condition or 
cash flows, we believe that the impact of the pandemic will be dependent on future developments, including the duration of the 
pandemic, the prevalence, strength and duration of restrictive measures and the resulting effects on our tenants, potential future 
tenants, the commercial real estate industry and the broader economy, all of which are uncertain and difficult to predict.  

31

Nevertheless, we believe at this time that there is more inherent risk associated with the operations of our Regional Office 
properties than our Defense/IT Locations.

We believe that COVID-19 led to several leases being executed later than we previously expected, and the inability for us 

to physically show space to prospective tenants for a period of time due to restrictive measures served as an impediment to 
initiating new and progressing active leasing transactions.  While we do not believe that our development leasing and ability to 
renew leases scheduled to expire have been significantly affected by the pandemic, we do believe that the impact of the 
restrictive measures and the economic uncertainty caused by the pandemic has impacted our timing and volume of vacant space 
leasing, and may continue to do so in the future.

For our development activity, we have delivered space in ten newly-developed properties and expansions of three fully-
operational properties on schedule since March 2020, and the 11 properties that were under development as of December 31, 
2020 face minimal operational risk as they were 84% leased as of the date of this filing.  COVID-19 enhances the risk of us 
being able to stay on pace to complete development and begin operations on schedule due to the potential for delays from: 
jurisdictional permitting and inspections; factories’ ability to provide materials; and possible labor quarantines.  These types of 
issues have not significantly affected us to date but could in the future, depending on COVID-19 related developments.

We do not expect that we will be required to incur significant additional capital expenditures on existing properties as a 

result of COVID-19.

In March 2020, due to the potential for financial market instability from the pandemic, we borrowed under our Revolving 

Credit Facility in order to pre-fund our short-term capital needs.  As the capital markets remained stable in the second quarter of 
2020, we repaid much of these borrowings in June 2020.  We subsequently completed an issuance of $400.0 million in 
unsecured senior notes in September 2020, which enabled us to refinance $300.0 million in notes maturing in 2021, and we 
have no other significant debt maturities until 2022.

Critical Accounting Policies and Estimates  

Our consolidated financial statements are prepared in accordance with GAAP, which require us to make certain estimates 

and assumptions. A summary of our significant accounting policies is provided in Note 2 to our consolidated financial 
statements.  The following section is a summary of certain aspects of those accounting policies involving estimates and 
assumptions that (1) require our most difficult, subjective or complex judgments in accounting for uncertain matters or matters 
that are susceptible to change and (2) materially affect our reported operating performance or financial condition.  It is possible 
that the use of different reasonable estimates or assumptions in making these judgments could result in materially different 
amounts being reported in our consolidated financial statements.  While reviewing this section, refer to Note 2 to our 
consolidated financial statements, including terms defined therein.

Assessment of Lease Term

As discussed above, a significant portion of our portfolio is leased to the USG, and the majority of those leases consist of a 
series of one-year renewal options, and/or provide for early termination rights.  In addition, certain other leases in our portfolio 
provide early termination rights to tenants.  Applicable accounting guidance requires us to recognize minimum rental payments 
on a straight-line basis over the term of each lease.  The term of a lease includes the noncancellable periods of the lease along 
with periods covered by: (1) a tenant option to extend the lease if the tenant is reasonably certain to exercise that option; (2) a 
tenant option to terminate the lease if the tenant is reasonably certain not to exercise that option; and (3) an option to extend (or 
not to terminate) the lease in which exercise of the option is controlled by us as the lessor.  When assessing the expected lease 
end date, we use judgment in contemplating the significance of: any penalties a tenant may incur should it choose not to 
exercise any existing options to extend the lease or exercise any existing options to terminate the lease; and economic incentives 
for the tenant based on any existing contract, asset, entity or market-based factors in the lease.  Factors we consider in making 
this assessment include the uniqueness of the purpose or location of the property, the availability of a comparable replacement 
property, the relative importance or significance of the property to the continuation of the lessee’s line of business and the 
existence of tenant leasehold improvements or other assets whose value would be impaired by the lessee vacating or 
discontinuing use of the leased property.  For most of our leases with the USG, we have determined, based on the factors above, 
that exercise of existing renewal options, or continuation of such leases without exercising early termination rights, is 
reasonably certain as it relates to the expected lease end date.  Changes in these lease term assessments could result in the write-
off of any recorded assets associated with straight-line rental revenue and acceleration of depreciation and amortization expense 
associated with costs we incurred related to these leases.

32

Impairment of Long-Lived Assets

We assess the asset groups associated with each of our properties, including operating properties, properties in 

development, land held for future development, related intangible assets, right-of-use assets, deferred rents receivable and lease 
liabilities, for indicators of impairment quarterly or when circumstances indicate that an asset group may be impaired.  If our 
analyses indicate that the carrying values of certain properties’ asset groups may be impaired, we perform a recovery analysis 
for such asset groups.  For properties to be held and used, we analyze recoverability based on the estimated undiscounted future 
cash flows expected to be generated from the operations and eventual disposition of the properties over, in most cases, a ten-
year holding period.  If we believe it is more likely than not that we will dispose of the properties earlier, we analyze 
recoverability using a probability weighted analysis of the estimated undiscounted future cash flows expected to be generated 
from the operations and eventual disposition of the properties over the various possible holding periods.  If the analysis 
indicates that the carrying value of a tested property’s asset group is not recoverable from its estimated future cash flows, the 
property’s asset group is written down to the property’s estimated fair value and an impairment loss is recognized.  If and when 
our plans change, we revise our recoverability analyses of such property’s asset group to use the cash flows expected from the 
operations and eventual disposition of such property using holding periods that are consistent with our revised plans.  

Property fair values are estimated based on contract prices, indicative bids, discounted cash flow analyses or comparable 

sales analyses.  Estimated cash flows used in our impairment analyses are based on our plans for the property and our views of 
market and economic conditions.  The estimates consider items such as current and future market rental and occupancy rates, 
estimated operating and capital expenditures and recent sales data for comparable properties; most of these items are influenced 
by market data obtained from real estate leasing and brokerage firms and our direct experience with the properties and their 
markets.  Determining the appropriate capitalization or discount 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 property.  
Changes in the estimated future cash flows due to changes in our plans for a property (especially our expected holding period), 
views of market and economic conditions and/or our ability to obtain development rights could result in recognition of 
impairment losses which could be substantial.

Asset groups associated with properties held for sale are carried at the lower of their carrying values (i.e., cost less 
accumulated depreciation and any impairment loss recognized, where applicable) or estimated fair values less costs to sell.  
Accordingly, decisions to sell certain properties will result in impairment losses if the carrying values of the specific properties’ 
asset groups classified as held for sale exceed such properties’ estimated fair values less costs to sell.  The estimates of fair 
value consider matters such as recent sales data for comparable properties and, where applicable, contracts or the results of 
negotiations with prospective purchasers.  These estimates are subject to revision as market conditions, and our assessment of 
such conditions, change. 

Revenue Recognition on Tenant Improvements

Most of our leases provide for some form of improvements to leased space.  When we are required to provide 

improvements under the terms of a lease, we need to determine whether the improvements constitute landlord assets or tenant 
assets.  If the improvements are landlord assets, we capitalize the cost of the improvements and recognize depreciation expense 
over the shorter of the useful life of the assets or the term of the lease and recognize any payments from the tenant as rental 
revenue over the term of the lease.  If the improvements are tenant assets, we defer the cost of improvements funded by us as a 
lease incentive asset and amortize it as a reduction of rental revenue over the term of the lease.  Our determination of whether 
improvements are landlord assets or tenant assets also may affect when we commence revenue recognition in connection with a 
lease. 

In determining whether improvements constitute landlord or tenant assets, we consider numerous factors that may require 

subjective or complex judgments, including, whether the economic substance of the lease terms is properly reflected and 
whether the improvements: have value to us as real estate; are unique to the tenant or reusable by other tenants; may be altered 
or removed by the tenant without our consent or without compensating us for any lost fair value; are owned, and remain, with 
us or the tenant at the end of the lease term.

For the changes in revenue concentration reflected above between year end 2019 and 2020, the increase in Redstone Arsenal, 
Data Center Shells and Regional Office was due to new, fully-occupied properties being placed in service, while the decrease in 
Fort Meade/BW Corridor was due to the effect of increases in other segments coupled with a decrease in that segment’s 
occupancy.

Includes lease terminations and space reductions occurring in connection with lease renewals.

With regard to changes in occupancy from December 31, 2019 to December 31, 2020:

•

•
•

•

Total: Increase was due primarily to placing into service 1.8 million square feet in space that was 99.5% leased as of 
December 31, 2020;
Fort Meade/BW Corridor: Decrease was due primarily to vacated space, resulting in a 70.8% retention rate in 2020;
Northern Virginia Defense/IT, Navy Support Locations and Regional Office: Increases each due to vacant space leasing; 
and
Other: Included two properties totaling 157,000 square feet in Aberdeen, Maryland. 

In 2020, we leased 3.6 million square feet, including 1.0 million square feet of development and redevelopment space 

discussed in further detail above. 

In 2020, we renewed leases on 2.2 million square feet, representing 80.6% of the square footage of our lease expirations 

(including the effect of early renewals).  The annualized rents of these renewals (totaling $28.35 per square foot) decreased on 
average by approximately 2.1% and the GAAP rents (totaling $28.45 per square foot) increased on average by approximately 
6.5% relative to the leases previously in place for the space.  The renewed leases had a weighted average lease term of 
approximately 4.2 years, with average rent escalations per year of 2.4%, and the per annum average estimated tenant 
improvements and lease costs associated with completing the leasing was approximately $2.03 per square foot.  The decrease in 
average rents on renewals was attributable primarily to per annum rent escalation terms of the previous leases that increased 
rents over the lease terms by amounts exceeding the increases in the applicable market rental rates. 

In 2020, we also completed leasing on 416,000 square feet of vacant space.  The annualized rents of this leasing totaled 
$31.32 per square foot and the GAAP rents totaled $32.36 per square foot; these leases had a weighted average lease term of 
approximately 6.2 years, with average rent escalations per year of 2.8%, and the per annum average estimated tenant 
improvements and lease costs associated with completing this leasing was approximately $7.33 per square foot.

Wholesale Data Center

Our 19.25 megawatt wholesale data center was 86.7% leased as of December 31, 2020 and 76.9% leased as of December 

31, 2019, reflecting an increase from our leasing of 3.1 megawatts in April 2020.  We have a lease for 11.25 megawatts
perpetually renewing that may be terminated by either party with six months’ notice.

For our office and data center shell properties, our weighted average lease term as of December 31, 2020 was 

approximately six years.  We believe that the weighted average annualized rental revenue per occupied square foot for our 
office and data center shell leases expiring in 2021 was, on average, approximately 1.5% to 3.5% higher than estimated current 
market rents for the related space, with specific results varying by segment. Our wholesale data center had scheduled lease 
expirations in 2021 for 61% of its annualized rental revenue, which included a lease for 11.25 megawatts perpetually renewing 
that may be terminated by either party with six months’ notice.

Results of Operations

For a discussion of our results of operations comparison for 2019 and 2018, refer to our Annual Report on Form 10-K for 

the fiscal year ended December 31, 2019 filed on February 19, 2020.

We evaluate the operating performance of our properties using NOI from real estate operations, our segment performance 
measure, which includes: real estate revenues and property operating expenses; and the net of revenues and property operating 
expenses of real estate operations owned through unconsolidated real estate joint ventures (“UJVs”) that is allocable to COPT’s 
ownership interest (“UJV NOI allocable to COPT”).  We view our NOI from real estate operations as comprising the following 
primary categories:

•

•

office and data center shell properties:
•

stably owned and 100% operational throughout the two years being compared.  We define these as changes from 
“Same Properties.”  For further discussion of the concept of “operational,” refer to the section of Note 2 of the 
consolidated financial statements entitled “Properties”;
developed or redeveloped and placed into service that were not 100% operational throughout the two years being 
compared; and
disposed; and

•

•
our wholesale data center.

 In addition to owning properties, we provide construction management and other services.  The primary manner in which 

we evaluate the operating performance of our construction management and other service activities is through a measure we 
define as NOI from service operations, which is based on the net of the revenues and expenses from these activities.  The 
revenues and expenses from these activities consist primarily of subcontracted costs that are reimbursed to us by customers 
along with a management fee.  The operating margins from these activities are small relative to the revenue.  We believe NOI 
from service operations is a useful measure in assessing both our level of activity and our profitability in conducting such 
operations.

37

Since both of the measures discussed above exclude certain items includable in net income, reliance on these measures has 

limitations; management compensates for these limitations by using the measures simply as supplemental measures that are 
considered alongside other GAAP and non-GAAP measures.  A reconciliation of NOI from real estate operations and NOI from 
service operations to net income reported on the consolidated statements of operations of COPT and subsidiaries is provided in 
Note 17 to our consolidated financial statements.

Our Same Properties pool consisted of 144 properties, comprising 73.0% of our office and data center shell portfolio’s 
square footage as of December 31, 2020.  This pool of properties changed from the pool used for purposes of comparing 2019
and 2018 in our 2019 Annual Report on Form 10-K due to: the addition of five properties placed in service and 100% 
operational on or before January 1, 2019 and the removal of eight properties in which we sold a 90% interest.

Regarding the changes in NOI from real estate operations reported above:

•

•

•

•

•

our Same Properties pool reflects a net increase due primarily to: increased occupancy and higher expense reimbursements 
from tenants, partially offset by higher provisions for collectability losses and lower parking revenue (both of which were 
attributable to the effects of COVID-19);
developed and redeveloped properties placed in service reflects the effect of 20 properties placed in service in 2019 and 
2020; 
our wholesale data center decreased due primarily to lease termination revenue recognized in the prior year that did not 
recur in the current year;
dispositions, net of retained interests in newly-formed UJVs reflects the effect of our decrease in ownership of eight data 
center shells in 2020 and nine data center shells in 2019; and 
Other reflects primarily the effect of previously operational properties that we removed from service in mid-2019.

Construction contract and other service revenue and expenses decreased due primarily to a lower volume of construction 
activity in connection with several of our tenants.  Construction contract activity is inherently subject to significant variability 
depending on the volume and nature of projects undertaken by us primarily on behalf of tenants.  Service operations are an 
ancillary component of our overall operations that typically contribute an insignificant amount of income relative to our real 
estate operations. 

General, Administrative and Leasing Expenses

General, administrative and leasing expenses decreased in large part due to lower professional fees and compensation 

related expenses in the current period.

We capitalize compensation and indirect costs associated with properties, or portions thereof, undergoing development or 

redevelopment activities.  Our capitalized compensation and indirect costs totaled $9.4 million in 2020 and $10.1 million in 
2019.

The increase in interest expense recognized on interest rate swaps was attributable to a decrease in applicable LIBOR rates, 
while these decreased rates and lower borrowings on our Revolving Credit Facility resulted in the decrease in interest on our 
Revolving Credit Facility.

Our average outstanding debt was $2.1 billion in 2020 and $1.9 billion 2019, and our weighted average effective interest 

rate on debt was approximately 3.6% in 2020 and 4.1% in 2019. 

 Gain on sales of real estate

Gain on sales of real estate included gains from sales of 90% interests in data center shell properties, including two 

properties in 2020 and nine properties in 2019.  We retained 10% interests in these properties through unconsolidated real estate 
joint ventures.

Gain on sale of investment in unconsolidated real estate joint venture

The gain on sale of investment in unconsolidated real estate joint venture recognized in 2020 was attributable to our 
decrease in ownership interest in six data center shell properties resulting from the sale of properties from GI-COPT to B RE 
COPT and subsequent dissolution of GI-COPT described above. 

Loss on extinguishment of debt

The loss on early extinguishment of debt recognized in 2020 was attributable to our purchase and redemption of 

3.70% Senior Notes due 2021.

Loss on interest rate derivatives

In 2020, we recognized a loss on interest rate swaps previously designated as cash flow hedges of interest expense on 

forecasted future borrowings following our determination that such borrowings would probably not occur.  

Funds from Operations

Funds from operations (“FFO”) is defined as net income computed using GAAP, excluding gains on sales and impairment 

losses of real estate (net of associated income tax) and real estate-related depreciation and amortization.  FFO also includes 
adjustments to net income for the effects of the items noted above pertaining to UJVs that were allocable to our ownership 
interest in the UJVs.  We believe that we use the Nareit definition of FFO, although others may interpret the definition 
differently and, accordingly, our presentation of FFO may differ from those of other REITs.  We believe that FFO is useful to 
management and investors as a supplemental measure of operating performance because, by excluding gains on sales and 
impairment losses of real estate and investments in unconsolidated real estate joint ventures (net of associated income tax), and 
real estate-related depreciation and amortization, FFO can help one compare our operating performance between periods.  In 
addition, since most equity REITs provide FFO information to the investment community, we believe that FFO is useful to 
investors as a supplemental measure for comparing our results to those of other equity REITs.  We believe that net income is 
the most directly comparable GAAP measure to FFO.

Since FFO excludes certain items includable in net income, reliance on the measure has limitations; management 

compensates for these limitations by using the measure simply as a supplemental measure that is weighed in balance with other 
GAAP and non-GAAP measures. FFO is not necessarily an indication of our cash flow available to fund cash needs.  
Additionally, it should not be used as an alternative to net income when evaluating our financial performance or to cash flow 
from operating, investing and financing activities when evaluating our liquidity or ability to make cash distributions or pay debt 
service.

Basic FFO available to common share and common unit holders (“Basic FFO”) is FFO adjusted to subtract (1) preferred 

share dividends, (2) income attributable to noncontrolling interests through ownership of preferred units in the Operating 
Partnership or interests in other consolidated entities not owned by us, (3) depreciation and amortization allocable to 
noncontrolling interests in other consolidated entities, (4) Basic FFO allocable to share-based compensation awards and (5) 
issuance costs associated with redeemed preferred shares.  With these adjustments, Basic FFO represents FFO available to 
common shareholders and common unitholders.  Common units in the Operating Partnership are substantially similar to our 
common shares and are exchangeable into common shares, subject to certain conditions.  We believe that Basic FFO is useful 
to investors due to the close correlation of common units to common shares.  We believe that net income is the most directly 
comparable GAAP measure to Basic FFO.  Basic FFO has essentially the same limitations as FFO; management compensates 
for these limitations in essentially the same manner as described above for FFO.

41

 
 
 
Diluted FFO available to common share and common unit holders (“Diluted FFO”) is Basic FFO adjusted to add back any 

changes in Basic FFO that would result from the assumed conversion of securities that are convertible or exchangeable into 
common shares.  We believe that Diluted FFO is useful to investors because it is the numerator used to compute Diluted FFO 
per share, discussed below.  We believe that net income is the most directly comparable GAAP measure to Diluted FFO.  Since 
Diluted FFO excludes certain items includable in the numerator to diluted EPS, reliance on the measure has limitations; 
management compensates for these limitations by using the measure simply as a supplemental measure that is weighed in the 
balance with other GAAP and non-GAAP measures.  Diluted FFO is not necessarily an indication of our cash flow available to 
fund cash needs.  Additionally, it should not be used as an alternative to net income when evaluating our financial performance 
or to cash flow from operating, investing and financing activities when evaluating our liquidity or ability to make cash 
distributions or pay debt service.

Diluted FFO available to common share and common unit holders, as adjusted for comparability is defined as Diluted FFO 

adjusted to exclude operating property acquisition costs; gain or loss on early extinguishment of debt; FFO associated with 
properties securing non-recourse debt on which we have defaulted and which we have extinguished, or expect to extinguish, via 
conveyance of such properties, including property NOI, interest expense and gains on debt extinguishment (discussed further 
below); loss on interest rate derivatives; demolition costs on redevelopment and nonrecurring improvements; executive 
transition costs; issuance costs associated with redeemed preferred shares; allocations of FFO to holders on noncontrolling 
interests resulting from capital events; and certain other expenses that we believe are not closely correlated with our operating 
performance.  This measure also includes adjustments for the effects of the items noted above pertaining to UJVs that were 
allocable to our ownership interest in the UJVs.  We believe this to be a useful supplemental measure alongside Diluted FFO as 
it excludes gains and losses from certain investing and financing activities and certain other items that we believe are not 
closely correlated to (or associated with) our operating performance.  We believe that net income is the most directly 
comparable GAAP measure to this non-GAAP measure.  This measure has essentially the same limitations as Diluted FFO, as 
well as the further limitation of not reflecting the effects of the excluded items; we compensate for these limitations in 
essentially the same manner as described above for Diluted FFO. 

Diluted FFO per share is (1) Diluted FFO divided by (2) the sum of the (a) weighted average common shares outstanding 
during a period, (b) weighted average common units outstanding during a period and (c) weighted average number of potential 
additional common shares that would have been outstanding during a period if other securities that are convertible or 
exchangeable into common shares were converted or exchanged.  We believe that Diluted FFO per share is useful to investors 
because it provides investors with a further context for evaluating our FFO results in the same manner that investors use 
earnings per share (“EPS”) in evaluating net income available to common shareholders.  In addition, since most equity REITs 
provide Diluted FFO per share information to the investment community, we believe that Diluted FFO per share is a useful 
supplemental measure for comparing us to other equity REITs. We believe that diluted EPS is the most directly comparable 
GAAP measure to Diluted FFO per share. Diluted FFO per share has most of the same limitations as Diluted FFO (described 
above); management compensates for these limitations in essentially the same manner as described above for Diluted FFO.

Diluted FFO per share, as adjusted for comparability is (1) Diluted FFO, as adjusted for comparability divided by (2) the 
sum of the (a) weighted average common shares outstanding during a period, (b) weighted average common units outstanding 
during a period and (c) weighted average number of potential additional common shares that would have been outstanding 
during a period if other securities that are convertible or exchangeable into common shares were converted or exchanged.  We 
believe that this measure is useful to investors because it provides investors with a further context for evaluating our FFO 
results.  We believe this to be a useful supplemental measure alongside Diluted FFO per share as it excludes gains and losses 
from certain investing and financing activities and certain other items that we believe are not closely correlated to (or associated 
with) our operating performance.  We believe that diluted EPS is the most directly comparable GAAP measure to this per share 
measure.  This measure has most of the same limitations as Diluted FFO (described above) as well as the further limitation of 
not reflecting the effects of the excluded items; we compensate for these limitations in essentially the same manner as described 
above for Diluted FFO. 

The computations for all of the above measures on a diluted basis assume the conversion of common units in COPLP but 
do not assume the conversion of other securities that are convertible into common shares if the conversion of those securities 
would increase per share measures in a given period.

We use measures called payout ratios as supplemental measures of our ability to make distributions to investors based on 
each of the following: FFO; Diluted FFO; and Diluted FFO, adjusted for comparability.  These measures are defined as (1) the 
sum of (a) dividends on unrestricted common shares and (b) distributions to holders of interests in COPLP (excluding unvested 

42

 
 
 
 
share-based compensation awards) and dividends on convertible preferred shares when such distributions and dividends are 
included in Diluted FFO divided by either (2) FFO, Diluted FFO or Diluted FFO, adjusted for comparability. 

The table below sets forth the computation of the above stated measures for 2020 and 2019 and provides reconciliations to 

the GAAP measures of COPT and subsidiaries associated with such measures:

Cash Flows

Net cash flow from operating activities increased $9.9 million, or 4.3%, from 2019 to 2020 due primarily to the timing of 

cash outlays for construction contract costs relative to the cash receipts from customers associated with such costs. 

Net cash flow used in investing activities increased $187.8 million from 2019 to 2020 due primarily to proceeds from sales 
of real estate interests of $143.0 million in the current period compared to $309.6 million in the prior period, partially offset by 
the effect of $53.1 million paid to cash settle interest rate swaps in the current period.

Net cash flow provided by financing activities in 2020 was $91.3 million and included primarily the following:

net proceeds from debt borrowings of $252.0 million, which included $150.0 million in borrowings under a term loan 
facility and the net increase from our issuance of the 2.25% Notes and the purchase and redemption of the 3.70% Notes; 
offset in part by 
dividends and/or distributions to equity holders of $125.2 million; 
distributions paid to redeemable noncontrolling interests of $14.4 million; and
our redemption of the Series I Preferred Units for $8.8 million.

Net cash flow used in financing activities in 2019 was $84.4 million and included primarily the following:

dividends and/or distributions to equity holders of $124.8 million; offset in part by
net proceeds from the issuance of common shares (or units) of $46.4 million.

Liquidity and Capital Resources of COPT

COPLP is the entity through which COPT, the sole general partner of COPLP, conducts almost all of its operations and 

owns almost all of its assets.  COPT occasionally issues public equity but does not otherwise generate any capital itself or 
conduct any business itself, other than incurring certain expenses in operating as a public company which are fully reimbursed 
by COPLP.  COPT itself does not hold any indebtedness, and its only material asset is its ownership of partnership interests of 
COPLP.  COPT’s principal funding requirement is the payment of dividends on its common and preferred shares.  COPT’s 
principal source of funding for its dividend payments is distributions it receives from COPLP. 

As of December 31, 2020, COPT owned 98.6% of the outstanding common units in COPLP and there were no preferred 

units outstanding.  As the sole general partner of COPLP, COPT has the full, exclusive and complete responsibility for 
COPLP’s day-to-day management and control. 

The liquidity of COPT is dependent on COPLP’s ability to make sufficient distributions to COPT.  The primary cash 

requirement of COPT is its payment of dividends to its shareholders.  COPT also guarantees some of the Operating 
Partnership’s debt, as discussed further in Note 10 of the notes to consolidated financial statements included herein. If the 
Operating Partnership fails to fulfill certain of its debt requirements, which trigger COPT’s guarantee obligations, then COPT 
will be required to fulfill its cash payment commitments under such guarantees.  However, COPT’s only significant asset is its 
investment in COPLP. 

44

 
 
As discussed further below, we believe that the Operating Partnership’s sources of working capital, specifically its cash 
flow from operations, and borrowings available under its Revolving Credit Facility, are adequate for it to make its distribution 
payments to COPT and, in turn, for COPT to make its dividend payments to its shareholders.  

COPT’s short-term liquidity requirements consist primarily of funds to pay for future dividends expected to be paid to its 
shareholders.  COPT periodically accesses the public equity markets to raise capital by issuing common and/or preferred shares.  

For COPT to maintain its qualification as a REIT, it must pay dividends to its shareholders aggregating annually to at least 

90% of its ordinary taxable income.  As a result of this distribution requirement, it cannot rely on retained earnings to fund its 
ongoing operations to the same extent that some other companies can.  COPT may need to continue to raise capital in the equity 
markets to fund COPLP’s development activities and acquisitions.

Liquidity and Capital Resources of COPLP

COPLP’s primary cash requirements are for operating expenses, debt service, development of new properties and 
improvements to existing properties.  We expect COPLP to continue to use cash flow provided by operations as the primary 
source to meet its short-term capital needs, including property operating expenses, general and administrative expenses, interest 
expense, scheduled principal amortization of debt, distributions to its security holders and improvements to existing properties.  
As of December 31, 2020, COPLP had $18.4 million in cash and cash equivalents. 

COPLP’s senior unsecured debt is currently rated investment grade by the three major rating agencies.  We aim to maintain 
an investment grade rating to enable COPLP to use debt comprised of unsecured, primarily fixed-rate debt (including the effect 
of interest rate swaps) from public markets and banks.  COPLP also uses secured nonrecourse debt from institutional lenders 
and banks primarily for joint venture financings.  In addition, COPLP periodically raises equity from COPT when COPT 
accesses the public equity markets by issuing common and/or preferred shares.  

COPLP uses its Revolving Credit Facility to initially finance much of its investing activities.  COPLP subsequently pays 

down the facility using cash available from operations and proceeds from long-term borrowings (net of any related hedging 
costs), equity issuances and sales of interests in properties.  The lenders’ aggregate commitment under the facility is $800.0 
million, with the ability for COPLP to increase the lenders’ aggregate commitment to $1.25 billion, provided that there is no 
default under the facility and subject to the approval of the lenders.  The facility matures in March 2023, and may be extended 
by two six-month periods at COPLP’s option, provided that there is no default under the facility and COPLP pays an extension 
fee of 0.075% of the total availability under the facility for each extension period.  As of December 31, 2020, the maximum 
borrowing capacity under this facility totaled $800.0 million, of which $657.0 million was available.  

COPT has a program in place under which it may offer and sell common shares in at-the-market stock offerings having an 

aggregate gross sales price of up to $300 million.  Under this program, COPT may also, at its discretion, sell common shares 
under forward equity sales agreements.  The use of a forward equity sales agreement would enable us to lock in a price on a 
sale of common shares when the agreement is executed but defer receiving the proceeds from the sale until a later date.

We believe that COPLP’s liquidity and capital resources are adequate for its near-term and longer-term requirements 
without necessitating property sales.  However, we may dispose of interests in properties opportunistically or when capital 
markets otherwise warrant.  We believe that we have the ability to raise additional equity by selling interests in data center 
shells through joint ventures.

(1) The contractual obligations set forth in this table exclude contracts for property operations and certain other contracts entered into in the 

normal course of business.  Also excluded are accruals and payables incurred and interest rate derivative liabilities, which are reflected in 
our reported liabilities (although debt and lease liabilities are included on the table).

(2) Represents scheduled principal amortization payments and maturities only and therefore excludes net debt discounts and deferred 

financing costs of $14.5 million.  As of December 31, 2020, maturities included $143.0 million in 2023 that may be extended to 2024, 
subject to certain conditions.

(3) We expect to pay these items using cash flow from operations.
(4) Represents interest costs for our outstanding debt as of December 31, 2020 for the terms of such debt.  For variable rate debt, the 

amounts reflected above used December 31, 2020 interest rates on variable rate debt in computing interest costs for the terms of such 
debt.  We expect to pay these items using cash flow from operations.

(5) Represents contractual obligations pertaining to new development and redevelopment activities.
(6) Due to the long-term nature of certain development and construction contracts and leases included in these lines, the amounts reported in 

the table represent our estimate of the timing for the related obligations being payable.

(7) Represents contractual obligations pertaining to projects for which we are acting as construction manager on behalf of unrelated parties 

who are our clients.  We expect to be reimbursed in full for these costs by our clients.

We expect to spend $275 million to $300 million on development costs and approximately $85 million on improvements 
and leasing costs for operating properties (including the commitments set forth in the table above) in 2021.  We expect to fund 
the development costs initially using primarily borrowings under our Revolving Credit Facility.  We expect to fund 
improvements to existing operating properties using cash flow from operating activities. 

Certain of our debt instruments require that we comply with a number of restrictive financial covenants, including 

maximum leverage ratio, unencumbered leverage ratio, minimum net worth, minimum fixed charge coverage, minimum 
unencumbered interest coverage ratio, minimum debt service and maximum secured indebtedness ratio.  As of December 31, 
2020, we were compliant with these covenants.

Off-Balance Sheet Arrangements

We had no material off-balance sheet arrangements during 2020. 

Inflation

Most of our tenants are obligated to pay their share of a property’s operating expenses to the extent such expenses exceed 

amounts established in their leases, which are based on historical expense levels.  Some of our tenants are obligated to pay their 
full share of a building’s operating expenses.  These arrangements somewhat reduce our exposure to increases in such costs 
resulting from inflation.

Item 7A.           Quantitative and Qualitative Disclosures about Market Risk

We are exposed to certain market risks, one of the most predominant of which is a change in interest rates.  Increases in 
interest rates can result in increased interest expense under our Revolving Credit Facility and other variable rate debt.  Increases 
in interest rates can also result in increased interest expense when our fixed rate debt matures and needs to be refinanced.

maturing each year (dollars in thousands):

(2) As of December 31, 2020, maturities included $143.0 million in 2023 that may be extended to 2024, subject to certain conditions.
(3) The amounts reflected above used interest rates as of December 31, 2020 for variable rate debt.

The fair value of our debt was $2.1 billion as of December 31, 2020 and $1.9 billion as of December 31, 2019.  If interest 

rates had been 1% lower, the fair value of our fixed-rate debt would have increased by approximately $52 million as of 
December 31, 2020 and $45 million as of December 31, 2019.

See Note 11 to our consolidated financial statements for information pertaining to interest rate swap contracts in place as of 

December 31, 2020 and 2019 and their respective fair values.

Based on our variable-rate debt balances, including the effect of interest rate swap contracts, our interest expense would 
have increased by $2.2 million in 2020 and $2.0 million in 2019 if the applicable LIBOR rate was 1% higher.  Interest expense 
in 2020 was more sensitive to a change in interest rates than 2019 due primarily to our having a higher average variable-rate 
debt balance in 2020 including the effect of interest rate derivatives in place.

Corporate Office Properties Trust Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, and for 

performing an assessment of the effectiveness of internal control over financial reporting as of December 31, 2020.  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.  Our internal control over financial reporting includes those policies and procedures that (i) pertain to the 
maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) 
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in 
accordance with authorizations of our management and trustees; and (iii) provide reasonable assurance regarding prevention or 
timely detection of unauthorized acquisition, use or disposition of our 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.

Management performed an assessment of the effectiveness of our internal control over financial reporting as of 

December 31, 2020 based upon criteria in Internal Control - Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (“COSO”).  Based on our assessment, management determined that our internal 
control over financial reporting was effective as of December 31, 2020 based on the criteria in Internal Control - Integrated 
Framework (2013) issued by the COSO. 

The effectiveness of our internal control over financial reporting as of December 31, 2020 has been audited by 

PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of Corporate Office Properties Trust

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Corporate Office Properties Trust and its subsidiaries (the 
“Company”) as of December 31, 2020 and 2019, and the related consolidated statements of operations, of comprehensive 
income, of equity and of cash flows for each of the three years in the period ended December 31, 2020, including the related 
notes and financial statement schedule listed in the accompanying index (collectively referred to as the “consolidated financial 
statements”). We also have audited 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 (COSO).

In our opinion, the consolidated financial statements referred to above 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. Also 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 the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, 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 
opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting 
based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United 
States) (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 
audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, 
whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material 
respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement 
of the consolidated 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 consolidated 
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 consolidated financial statements. Our audit of internal 
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the 
risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based 
on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the 
circumstances. We believe that our audits provide a reasonable basis for our opinions.

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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (ii) 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 trustees of the 
company; and (iii) 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.

F-4

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.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial 
statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or 
disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or 
complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated 
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. 

Determination of Expected Lease End Date for United States Government Leases with One-year Renewal Options and/or Early 
Termination Rights

As described in Notes 2 and 5 to the consolidated financial statements, total lease revenue for the year ended December 31, 
2020 was $536.1 million and a significant portion of the Company’s leases are with the United States Government, which 
represented 25% of the fixed lease revenues for the year ended December 31, 2020. The majority of United States Government 
leases contain one-year renewal options and/or provide for early termination rights. The Company recognizes minimum rental 
payments on a straight-line basis over the terms of each lease. The lease term of a lease includes the noncancellable periods of 
the lease along with periods covered by: (1) a tenant option to extend the lease if the tenant is reasonably certain to exercise that 
option; (2) a tenant option to terminate the lease if the tenant is reasonably certain not to exercise that option; and (3) an option 
to extend (or not to terminate) the lease in which exercise of the option is controlled by the Company as the lessor. When 
assessing the expected lease end date, management uses judgment in contemplating the significance of any penalties a tenant 
may incur should it choose not to exercise any existing options to extend the lease or exercise any existing options to terminate 
the lease; and economic incentives for the tenant based on any existing contract, asset, entity or market-based factors in the 
lease. 

The principal considerations for our determination that performing procedures relating to the determination of the expected 
lease end date for United States Government leases with one-year renewal options and/or early termination rights is a critical 
audit matter are the significant judgments by management when determining the expected lease end date for the United States 
Government leases with one-year renewal options and/or early termination rights, which in turn led to a high degree of auditor 
judgment, subjectivity and audit effort in performing procedures and evaluating audit evidence relating to the determination of 
such expected lease end dates.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall 
opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Unitholders of Corporate Office Properties, L.P. 

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Corporate Office Properties, L.P. and its subsidiaries (the 
“Operating Partnership”) as of December 31, 2020 and 2019, and the related consolidated statements of operations, of 
comprehensive income, of equity and of cash flows for each of the three years in the period ended December 31, 2020, 
including the related notes and financial statement schedule listed in the accompanying index (collectively referred to as the 
“consolidated financial statements”). We also have audited 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 (COSO).

In our opinion, the consolidated financial statements referred to above 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. Also in our opinion, the Operating Partnership 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 the COSO.

Basis for Opinions

The Operating Partnership’s management is responsible for these consolidated financial statements, 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 opinions on the Operating Partnership’s consolidated financial statements and on the Operating Partnership’s internal 
control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company 
Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Operating 
Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and 
Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, 
whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material 
respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement 
of the consolidated 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 consolidated 
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 consolidated financial statements. Our audit of internal 
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the 
risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based 
on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the 
circumstances. We believe that our audits provide a reasonable basis for our opinions.

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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (ii) 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 trustees of the 
company; and (iii) 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.

F-6

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.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial 
statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or 
disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or 
complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated 
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. 

Determination of Expected Lease End Date for United States Government Leases with One-year Renewal Options and/or Early 
Termination Rights

As described in Notes 2 and 5 to the consolidated financial statements, total lease revenue for the year ended December 31, 
2020 was $536.1 million and a significant portion of the Operating Partnership’s leases are with the United States Government, 
which represented 25% of the fixed lease revenues for the year ended December 31, 2020. The majority of United States 
Government leases contain one-year renewal options and/or provide for early termination rights. The Operating Partnership 
recognizes minimum rental payments on a straight-line basis over the terms of each lease. The lease term of a lease includes the 
noncancellable periods of the lease along with periods covered by: (1) a tenant option to extend the lease if the tenant is 
reasonably certain to exercise that option; (2) a tenant option to terminate the lease if the tenant is reasonably certain not to 
exercise that option; and (3) an option to extend (or not to terminate) the lease in which exercise of the option is controlled by 
the Operating Partnership as the lessor. When assessing the expected lease end date, management uses judgment in 
contemplating the significance of any penalties a tenant may incur should it choose not to exercise any existing options to 
extend the lease or exercise any existing options to terminate the lease; and economic incentives for the tenant based on any 
existing contract, asset, entity or market-based factors in the lease. 

The principal considerations for our determination that performing procedures relating to the determination of the expected 
lease end date for United States Government leases with one-year renewal options and/or early termination rights is a critical 
audit matter are the significant judgments by management when determining the expected lease end date for the United States 
Government leases with one-year renewal options and/or early termination rights, which in turn led to a high degree of auditor 
judgment, subjectivity and audit effort in performing procedures and evaluating audit evidence relating to the determination of 
such expected lease end dates.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall 
opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the 
revenue recognition for leases, including controls over the determination of the expected lease end dates for United States 
Government leases with one-year renewal options and/or early termination rights.  These procedures also included, among 
others, testing management’s process for determining the expected lease end date for a sample of United States Government 
leases with one-year renewal options and/or early termination rights, including evaluating the reasonableness of significant 
assumptions utilized by management, related to the significance of any penalties a tenant may incur should it choose not to 
exercise any existing options to extend the lease or exercise any existing options to terminate the lease; and economic incentives 
for the tenant based on any existing contract, asset, entity or market-based factors in the lease. Evaluating the assumptions 
included evaluating whether the assumptions used were reasonable considering past experience with the tenant and the rental 
property and whether the assumptions were consistent with evidence obtained in other areas of the audit.

Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries
Notes to Consolidated Financial Statements

1. 

Organization

Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company”) is a fully-integrated and self-
managed real estate investment trust (“REIT”).  Corporate Office Properties, L.P. (“COPLP”) and subsidiaries (collectively, the 
“Operating Partnership”) is the entity through which COPT, the sole general partner of COPLP, conducts almost all of its 
operations and owns almost all of its assets.  Unless otherwise expressly stated or the context otherwise requires, “we”, “us” 
and “our” as used herein refer to each of the Company and the Operating Partnership.  We own, manage, lease, develop and 
selectively acquire office and data center properties.  The majority of our portfolio is in locations that support the United States 
Government (“USG”) and its contractors, most of whom are engaged in national security, defense and information technology 
(“IT”) related activities servicing what we believe are growing, durable, priority missions (“Defense/IT Locations”).  We also 
own a portfolio of office properties located in select urban/urban-like submarkets in the Greater Washington, DC/Baltimore 
region with durable Class-A office fundamentals and characteristics (“Regional Office”).  As of December 31, 2020, our 
properties included the following (all references to number of properties, square footage, acres and megawatts are unaudited):

•

•
•

•

181 properties totaling 21.0 million square feet comprised of 16.2 million square feet in 155 office properties and 4.7 
million square feet in 26 single-tenant data center shell properties (“data center shells”).  We owned 17 of these data center 
shells through unconsolidated real estate joint ventures;
a wholesale data center with a critical load of 19.25 megawatts;
11 properties under development (nine office properties and two data center shells), including three partially-operational 
properties, that we estimate will total approximately 1.5 million square feet upon completion; and
approximately 830 acres of land controlled for future development that we believe could be developed into approximately 
10.4 million square feet and 43 acres of other land.

COPLP owns real estate directly and through subsidiary partnerships and limited liability companies (“LLCs”).  In addition to 
owning real estate, COPLP also owns subsidiaries that provide real estate services such as property management, development 
and construction services primarily for our properties but also for third parties.  Some of these services are performed by a 
taxable REIT subsidiary (“TRS”).

Equity interests in COPLP are in the form of common and preferred units.  As of December 31, 2020, COPT owned 98.6% 
of the outstanding COPLP common units (“common units”) and there were no preferred units outstanding.  Common units not 
owned by COPT carry certain redemption rights.  The number of common units owned by COPT is equivalent to the number of 
outstanding common shares of beneficial interest (“common shares”) of COPT, and the entitlement of common units to 
quarterly distributions and payments in liquidation is substantially the same as that of COPT common shareholders.

COPT’s common shares are publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “OFC”. 

Because COPLP is managed by COPT, and COPT conducts substantially all of its operations through COPLP, we refer to 

COPT’s executive officers as COPLP’s executive officers; similarly, although COPLP does not have a board of trustees, we 
refer to COPT’s Board of Trustees as COPLP’s Board of Trustees.

2.  

Summary of Significant Accounting Policies

Basis of Presentation

The COPT consolidated financial statements include the accounts of COPT, the Operating Partnership, their subsidiaries 

and other entities in which COPT has a majority voting interest and control.  The COPLP consolidated financial statements 
include the accounts of COPLP, its subsidiaries and other entities in which COPLP has a majority voting interest and control.  
We also consolidate certain entities when control of such entities can be achieved through means other than voting rights 
(“variable interest entities” or “VIEs”) if we are deemed to be the primary beneficiary of such entities.  We eliminate all 
intercompany balances and transactions in consolidation.

We use the equity method of accounting when we own an interest in an entity and can exert significant influence over but 

cannot control the entity’s operations.  We discontinue equity method accounting if our investment in an entity (and net 
advances) is reduced to zero unless we have guaranteed obligations of the entity or are otherwise committed to provide further 
financial support for the entity.

F-20

 
 
 
 
Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

When we own an equity investment in an entity and cannot exert significant influence over its operations, we measure the 

investment at fair value, with changes recognized through net income.  For an investment without a readily determinable fair 
value, we measure the investment at cost, less any impairments, plus or minus changes resulting from observable price changes 
for an identical or similar investment of the same issuer.  

Use of Estimates in the Preparation of Financial Statements

We make estimates and assumptions when preparing financial statements under generally accepted accounting principles 

(“GAAP”).  These estimates and assumptions affect various matters, including:

•
•
•

the reported amounts of assets and liabilities in our consolidated balance sheets as of the dates of the financial statements; 
the disclosure of contingent assets and liabilities as of the dates of the financial statements; and 
the reported amounts of revenues and expenses in our consolidated statements of operations during the reporting periods.  

Significant estimates are inherent in the presentation of our financial statements in a number of areas, including the 
evaluation of the collectability of accounts and deferred rent receivable, the determination of estimated useful lives of assets, 
the determination of lease terms, the evaluation of impairment of long-lived assets, the amount of impairment losses 
recognized, the allocation of property acquisition costs, the amount of revenue recognized relating to tenant improvements, the 
level of expense recognized in connection with share-based compensation and the determination of accounting method for 
investments.  Actual results could differ from these and other estimates.  

Properties

We report properties to be developed or held and used in operations at our depreciated cost, reduced for impairment losses.  

We capitalize direct and indirect project costs (including related compensation and other indirect costs), interest expense 
and real estate taxes associated with properties, or portions thereof, undergoing development or redevelopment activities.  In 
capitalizing interest expense, if there is a specific borrowing for a property undergoing development or redevelopment 
activities, we apply the interest rate of that borrowing to the average accumulated expenditures that do not exceed such 
borrowing; for the portion of expenditures exceeding any such specific borrowing, we apply our weighted average interest rate 
on other borrowings to the expenditures.  We continue to capitalize costs while development or redevelopment activities are 
underway until a property becomes “operational,” which occurs when lease terms commence (generally when the tenant has 
control of the leased space and we have delivered the premises to the tenant as required under the terms of such lease), but no 
later than one year after the cessation of major construction activities.  When leases commence on portions of a newly-
developed or redeveloped property in the period prior to one year from the cessation of major construction activities, we 
consider that property to be “partially operational.”  When a property is partially operational, we allocate the costs associated 
with the property between the portion that is operational and the portion under development.  We start depreciating costs 
associated with newly-developed or redeveloped properties as they become operational.  

Most of our leases provide for some form of improvements to leased space.  When we are required to provide 

improvements under the terms of a lease, we determine whether the improvements constitute landlord assets or tenant assets.  If 
the improvements are landlord assets, we capitalize the cost of the improvements and recognize depreciation expense over the 
shorter of the useful life of the assets or the term of the lease and recognize any payments from the tenant as rental revenue over 
the term of the lease.  If the improvements are tenant assets, we defer the cost of improvements funded by us as a lease 
incentive asset and amortize it as a reduction of rental revenue over the term of the lease.  In determining whether 
improvements constitute landlord or tenant assets, we consider numerous factors, including whether the economic substance of 
the lease terms is properly reflected and whether the improvements: have value to us as real estate; are unique to the tenant or 
reusable by other tenants; may be altered or removed by the tenant without our consent or without compensating us for any lost 
fair value; or are owned, and remain, with us or the tenant at the end of the lease term.

F-21

 
 
Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

We depreciate our fixed assets using the straight-line method over their estimated useful lives as follows:

Buildings and building improvements
Land improvements
Tenant improvements on operating properties

Estimated Useful Lives

10-40 years
10-20 years
Shorter of remaining useful lives of 

assets or related lease term

Equipment and personal property

3-10 years

For periods in which a property is classified as held for sale, we classify the assets of the property’s asset group as held for 

sale on our consolidated balance sheet for such periods.

When we dispose of, or classify as held for sale, a component (such as a reportable segment or sub-segment) or group of 

components that represents a strategic shift having a major effect on our operations and financial results (such as a major 
geographical area of operations or major line of business), we classify the associated results of operations as discontinued 
operations.  We had no properties newly classified as discontinued operations in the last three years.

Sales of Properties

We recognize gains from sales of consolidated interests in properties to non-customer third parties when we have 

transferred control of such interests. 

Impairment of Properties

We assess the asset groups associated with each of our properties, including operating properties, properties in 

development, land held for future development, related intangible assets, right-of-use assets, deferred rents receivable and lease 
liabilities for indicators of impairment quarterly or when circumstances indicate that an asset group may be impaired.  If our 
analyses indicate that the carrying values of certain properties’ asset groups may be impaired, we perform a recovery analysis 
for such asset groups.  For properties to be held and used, we analyze recoverability based on the estimated undiscounted future 
cash flows expected to be generated from the operations and eventual disposition of the properties over, in most cases, a ten-
year holding period.  If we believe it is more likely than not that we will dispose of the properties earlier, we analyze 
recoverability using a probability weighted analysis of the estimated undiscounted future cash flows expected to be generated 
from the operations and eventual disposition of the properties over the various possible holding periods.  If the analysis 
indicates that the carrying value of a tested property’s asset group is not recoverable from its estimated future cash flows, the 
property’s asset group is written down to the property’s estimated fair value and an impairment loss is recognized.  If and when 
our plans change, we revise our recoverability analyses to use the cash flows expected from the operations and eventual 
disposition of such property using holding periods that are consistent with our revised plans.  Changes in holding periods may 
require us to recognize impairment losses. 

Fair values are estimated based on contract prices, indicative bids, discounted cash flow analyses, yield analyses or 
comparable sales analyses.  Estimated cash flows used in our impairment analyses are based on our plans for the property and 
our views of market and economic conditions.  The estimates consider items such as current and future market rental and 
occupancy rates, estimated operating and capital expenditures and recent sales data for comparable properties; most of these 
items are influenced by market data obtained from real estate leasing and brokerage firms and our direct experience with the 
properties and their markets.

When we determine that a property is held for sale, we stop depreciating the property and estimate the property’s fair value, 

net of selling costs; if we then determine that the estimated fair value, net of selling costs, is less than the net book value of the 
property’s asset group, we recognize an impairment loss equal to the difference and reduce the net book value of the property’s 
asset group.

Acquisition of Operating Properties

Upon completion of operating property acquisitions, we allocate the purchase price to tangible and intangible assets and 
liabilities associated with such acquisitions based on our estimates of their fair values.  We determine these fair values by using 
market data and independent appraisals available to us and making numerous estimates and assumptions.  We allocate operating 
property acquisitions to the following components:

•

•

•

•

•

properties based on a valuation performed under the assumption that the property is vacant upon acquisition (the “if-vacant 
value”).  The if-vacant value is allocated between land and buildings or, in the case of properties under development, 
development in progress.  We also allocate additional amounts to properties for in-place tenant improvements based on our 
estimate of improvements per square foot provided under market leases that would be attributable to the remaining non-
cancelable terms of the respective leases;
above- and below-market lease intangible assets or liabilities based on the present value (using an interest rate which 
reflects the risks associated with the leases acquired) of the difference between: (1) the contractual amounts to be received 
pursuant to the in-place leases; and (2) our estimate of fair market lease rates for the corresponding space, measured over a 
period equal to the remaining non-cancelable term of the lease.  The capitalized above- and below-market lease values are 
amortized as adjustments to lease revenue over the remaining lease terms of the respective leases, and to renewal periods in 
the case of below-market leases;
in-place lease value based on our estimates of: (1) the present value of additional income to be realized as a result of leases 
being in place on the acquired properties; and (2) costs to execute similar leases.  Our estimate of costs to execute similar 
leases includes leasing commissions, legal and other related costs; 
tenant relationship value based on our evaluation of the specific characteristics of each tenant’s lease and our overall 
relationship with that respective tenant.  Characteristics we consider in determining these values include the nature and 
extent of our existing business relationships with the tenant, growth prospects for developing new business with the tenant, 
the tenant’s credit quality and expectations of lease renewals, among other factors; and
above- and below-market cost arrangements (such as real estate tax treaties or above- or below-market ground leases) 
based on the present value of the expected benefit from any such arrangements in place on the property at the time of 
acquisition.

Leased Assets, as a Lessee

Effective January 1, 2019, we adopted guidance requiring lessees to classify leases as either finance or operating leases 

based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee.  The 
resulting classification determines whether the lease expense is recognized based on an effective interest method or straight-line 
basis over the term of the lease.  The guidance also requires us to recognize upon lease term commencement a right-of-use asset 
and lease liability for all leases with a term of greater than 12 months regardless of their classification.  We adopted this 
guidance for leases on January 1, 2019 using a modified retrospective transition approach under which we elected to not adjust 
prior comparative reporting periods.  We elected to apply a package of practical expedients that enabled us to carry forward 
upon adoption our historical assessments of: expired or existing leases regarding their lease classification; and whether any 
expired or existing contracts are, or contain, leases.  We also elected a practical expedient that enabled us to avoid the need to 
assess whether expired or existing land easements not previously accounted for as leases are, or contain, a lease. 

In determining right-of-use assets and lease liabilities, we estimate an appropriate incremental borrowing rate on a fully-
collateralized basis for the terms of the leases.  Since the terms under our ground leases are usually significantly longer than the 
terms of borrowings available to us on a fully-collateralized basis, our estimate of this rate requires significant judgment, and 
considers factors such as interest rates available to us on a fully-collateralized basis for shorter-termed debt and U.S. Treasury 
rates.  

Cash and Cash Equivalents

Cash and cash equivalents include all cash and liquid investments that mature three months or less from when they are 
purchased.  Cash equivalents are reported at cost, which approximates fair value.  We maintain our cash in bank accounts in 
amounts that may exceed Federally insured limits at times.  We have not experienced any losses in these accounts in the past 
and believe that we are not exposed to significant credit risk because our accounts are deposited with major financial 
institutions.

Investments in Marketable Securities

We classify marketable securities as trading securities when we have the intent to sell such securities in the near term, and 
classify other marketable securities as available-for-sale securities.  We determine the appropriate classification of investments 
in marketable securities at the acquisition date and re-evaluate the classification at each balance sheet date.  We report 
investments in marketable securities classified as trading securities at fair value (which is included in the line entitled “Prepaid 
expenses and other assets, net” on our consolidated balance sheets), with unrealized gains and losses recognized through 
earnings; on our consolidated statements of cash flows, we classify cash flows from these securities as operating activities. 

Receivables and Credit Losses

We evaluate our receivables from customers and borrowers for collectability and recognize estimated credit losses on these 

receivables.  We use judgment in estimating these losses based upon the credit status of the entities associated with the 
individual receivables and payment history.  

Effective January 1, 2020, we adopted guidance issued by the Financial Accounting Standards Board (“FASB”) that 

changed how we measure credit losses for most financial assets and certain other instruments not measured at fair value through 
net income from an incurred loss model to an expected loss approach.  Our items within the scope of this guidance included the 
following:

•
•
•
•

•

investing receivables, as disclosed in Note 8;
tenant notes receivable;
net investment in sales-type leases;
other assets comprised of non-lease revenue related accounts receivable (primarily from construction contract services) and 
contract assets from unbilled construction contract revenue; and
off-balance sheet credit exposures.

Under this guidance, we recognize an estimate of our expected credit losses on these items as an allowance, as the guidance 
requires that financial assets be measured on an amortized cost basis and be presented at the net amount expected to be 
collected (or as a separate liability in the case of off-balance sheet credit exposures).   The allowance represents the portion of 
the amortized cost basis that we do not expect to collect (or loss we expect to incur in the case of off-balance sheet credit 
exposures) due to credit over the contractual life based on available information relevant to assessing the collectability of cash 
flows, which includes consideration of past events, current conditions and reasonable and supportable forecasts of future 
economic conditions (including consideration of asset- or borrower-specific factors).  The guidance requires the allowance for 
expected credit losses to reflect the risk of loss, even when that risk is remote.  An allowance for credit losses is measured and 
recorded upon the initial recognition of a financial asset (or off-balance sheet credit exposure), regardless of whether it is 
originated or purchased.  Quarterly, the expected losses are re-estimated, considering any cash receipts and changes in risks or 
assumptions, with resulting adjustments recognized as credit loss expense or recoveries on our consolidated statements of 
operations.

We estimate expected credit losses for in-scope items using historical loss rate information developed for varying 

classifications of credit risk and contractual lives.  Due to our limited quantity of items within the scope of this guidance and the 
unique risk characteristics of such items, we individually assign each in-scope item a credit risk classification.  The credit risk 
classifications assigned by us are determined based on credit ratings assigned by ratings agencies (as available) or are 
internally-developed based on available financial information, historical payment experience, credit documentation, other 
publicly available information and current economic trends.  In addition, for certain items in which the risk of credit loss is 
affected by the economic performance of a real estate development project, we develop probability weighted scenario analyses 
for varying levels of performance in estimating our credit loss allowance (applicable to our notes receivable from the City of 
Huntsville disclosed in Note 8 and a tax incremental financing obligation disclosed in Note 20).

For lease revenue, if collectability is not probable, revenue recognized is limited to the lesser of revenue that would have 
been recognized if collectability was probable or lease payments collected.  Losses on lease revenue receivables are presented 
on our consolidated statements of operation with property operating expenses for years prior to January 1, 2019, when we 
adopted new lease accounting guidance, and as reductions in lease revenue thereafter.  

F-24

Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

Prior to our adoption of the credit loss guidance discussed above, we evaluated the collectability of both interest and 
principal of loans whenever events or changes in circumstances indicated such amounts may not be recoverable.  A loan was 
impaired when it was probable that we would be unable to collect all amounts due according to the existing contractual terms.  
When a loan was impaired, the amount of the loss accrual was calculated by comparing the carrying amount of the investment 
to the present value of expected future cash flows discounted at the loan’s effective interest rate and the value of any collateral 
under such loan.

When we believe that collection of interest income on an investing or tenant note receivable is not probable, we place the 
receivable on nonaccrual status, meaning interest income is recognized when payments are received rather than on an accrual 
basis.  

We write off receivables when we believe the facts and circumstances indicate that continued pursuit of collection is no 
longer warranted.  When cash is received in connection with receivables for which we have previously recognized credit losses, 
we recognize reductions in our credit losses.

Intangible Assets and Deferred Revenue on Real Estate Acquisitions

We amortize the intangible assets and deferred revenue on real estate acquisitions discussed above as follows:

Asset Type
Above- and below-market leases
In-place lease value
Tenant relationship value

Above- and below-market cost arrangements

Amortization Period
Related lease terms
Related lease terms
Estimated period of time that tenant will lease 

space in property
Term of arrangements

We recognize the amortization of acquired above- and below-market leases as adjustments to rental revenue.  We recognize 

the amortization of above- and below-market cost arrangements as adjustments to property operating expenses.  We recognize 
the amortization of other intangible assets on property acquisitions as amortization expense.

Deferred Leasing Costs

We defer costs incurred to obtain new tenant leases or extend existing tenant leases; our deferral of costs included related 

non-incremental compensation costs until January 1, 2019, when we adopted new lease accounting guidance.  We amortize 
these costs evenly over the lease terms.  We classify leasing costs paid as an investing activity on our statements of cash flows 
since such costs are necessary in order for us to generate long-term future cash flows from our properties.  When tenant leases 
are terminated early, we expense any unamortized deferred leasing costs associated with those leases over the shortened term of 
the lease.  

Deferred Financing Costs

We defer costs of financing arrangements and recognize these costs as interest expense over the related debt terms on a 

straight-line basis, which approximates the amortization that would occur under the effective interest method of amortization. 
We expense any unamortized loan costs when loans are retired early.  We present deferred costs of financing arrangements as a 
direct deduction from the related debt liability, except for costs attributable to line-of-credit arrangements and interest rate 
derivatives, which we present in the balance sheet in the line entitled “prepaid expenses and other assets, net”.

Interest Rate Derivatives

Our primary objectives in using interest rate derivatives are to add stability to interest expense and to manage exposure to 
interest rate movements. To accomplish this objective, we use interest rate swaps as part of our interest rate risk management 
strategy.  Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in 
exchange for our making fixed-rate payments over the life of the agreements without exchange of the underlying notional 
amount.  We use interest rate swaps to hedge the cash flows associated with interest rates on variable-rate debt borrowings.  We 
also use forward-starting interest rate swaps to hedge the cash flows associated with interest rates on forecasted fixed-rate 
borrowings.  We recognize all derivatives as assets or liabilities on our consolidated balance sheet at fair value.  

We defer all changes in the fair value of designated cash flow hedges to accumulated other comprehensive income 
(“AOCI”) or loss (“AOCL”), reclassifying such deferrals to interest expense as interest expense is recognized on the hedged 
forecasted transactions.  When an interest rate swap designated as a cash flow hedge no longer qualifies for hedge accounting 
and the hedged transactions are probable not to occur, we recognize changes in fair value of the hedge previously deferred to 
AOCI or AOCL, along with any changes in fair value occurring thereafter, through earnings.  We do not use interest rate 
derivatives for trading or speculative purposes.  We manage counter-party risk by only entering into contracts with major 
financial institutions based upon their credit ratings and other risk factors.  

We use standard market conventions and techniques such as discounted cash flow analysis, option pricing models, 

replacement cost and termination cost in computing the fair value of derivatives at each balance sheet date.  We made an 
accounting policy election to use an exception provided for in the applicable accounting guidance with respect to measuring 
counterparty credit risk for derivative instruments; this election enables us to measure the fair value of groups of assets and 
liabilities associated with derivative instruments consistently with how market participants would price the net risk exposure as 
of the measurement date. 

Noncontrolling Interests

COPT’s consolidated noncontrolling interests are comprised of interests in COPLP not owned by COPT (discussed further 

in Note 14) and interests in consolidated real estate joint ventures not owned by us (discussed further in Note 6).  COPLP’s 
consolidated noncontrolling interests are comprised primarily of interests in our consolidated real estate joint ventures.  We 
evaluate whether noncontrolling interests are subject to redemption features outside of our control.  We classify noncontrolling 
interests that are currently redeemable for cash at the option of the holders or are probable of becoming redeemable as 
redeemable noncontrolling interests in the mezzanine section of our consolidated balance sheets; we adjust these interests each 
period to the greater of their fair value or carrying amount (initial amount as adjusted for allocations of income and losses and 
contributions and distributions), with a corresponding offset to additional paid-in capital on COPT’s consolidated balance 
sheets or common units on COPLP’s balance sheet.  Our other noncontrolling interests are reported in the equity section of our 
consolidated balance sheets. 

Revenue Recognition

Lease and Other Property Revenue

We lease real estate properties, comprised primarily of office properties and data center shells, to third parties.  These 
leases usually include options under which the tenant may renew its lease based on market rates at the time of renewal, which 
are then typically subject to further negotiation.  These leases occasionally provide the tenant with an option to terminate its 
lease early usually for a defined termination fee.  

F-26

Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

Most of our lease revenue is from fixed contractual payments defined under the lease that, in most cases, escalate annually 
over the term of the lease.  Our lease revenue also includes variable lease payments predominantly for tenant reimbursements of 
property operating expenses and lease termination fees.  Property operating expense reimbursement structures vary, with some 
tenants responsible for all of a property’s expenses, while others are responsible for their share of a property’s expense only to 
the extent such expenses exceed amounts defined in the lease (which are derived from the property’s historical expense levels).  
Lease termination fees in most cases result from a tenant’s exercise of an existing right under a lease.  

Upon lease commencement, we evaluate leases to determine if they meet criteria set forth in lease accounting guidance for 

classification as sales-type leases or direct financing leases; when a lease meets none of these criteria, we classify the lease as 
an operating lease.  Upon commencement of sales-type leases, we derecognize the underlying asset, recognizing in its place a 
net investment in the lease equal to the sum of the lease receivable and the present value of any unguaranteed residual asset and 
recognize any selling profit or loss created as a result of the difference between those two amounts.  Similarly, for direct 
financing leases, the lessor derecognizes the underlying asset and recognizes a net investment in the lease, but, unlike in a sales-
type lease, defers profit and amortizes it as interest income over the lease term.  Our leases of properties as lessor are 
predominantly classified as operating leases, for which the underlying asset remains on our balance sheet and is depreciated 
consistently with other owned assets, with income recognized as described further below. 

 We recognize minimum rents on operating leases, net of abatements, on a straight-line basis over the term of tenant leases.  

A lease term commences when: (1) the tenant has control of the leased space (legal right to use the property); and (2) we have 
delivered the premises to the tenant as required under the terms of such lease.  The term of a lease includes the noncancellable 
periods of the lease along with periods covered by: (1) a tenant option to extend the lease if the tenant is reasonably certain to 
exercise that option; (2) a tenant option to terminate the lease if the tenant is reasonably certain not to exercise that option; and 
(3) an option to extend (or not to terminate) the lease in which exercise of the option is controlled by us as the lessor.  When 
assessing the expected lease end date, we use judgment in contemplating the significance of: any penalties a tenant may incur 
should it choose not to exercise any existing options to extend the lease or exercise any existing options to terminate the lease; 
and economic incentives for the tenant based on any existing contract, asset, entity or market-based factors in the lease.  While 
a significant portion of our portfolio is leased to the USG, and the majority of those leases consist of a series of one-year 
renewal options, or provide for early termination rights, we have concluded that exercise of existing renewal options, or 
continuation of such leases without exercising early termination rights, is reasonably certain for most of these leases.

We report the amount by which our minimum rental revenue recognized on a straight-line basis under leases exceeds the 
contractual rent billings associated with such leases as deferred rent receivable on our consolidated balance sheets.  Amounts by 
which our minimum rental revenue recognized on a straight-line basis under leases are less than the contractual rent billings 
associated with such leases are reported in liabilities as deferred revenue associated with operating leases on our consolidated 
balance sheets.  

In connection with a tenant’s entry into, or modification of, a lease, if we make cash payments to, or on behalf of, the 
tenant for purposes other than funding the construction of landlord assets, we defer the amount of such payments as lease 
incentives.  As discussed above, when we are required to provide improvements under the terms of a lease, we determine 
whether the improvements constitute landlord assets or tenant assets; if the improvements are tenant assets, we defer the cost of 
improvements funded by us as a lease incentive asset.  We amortize lease incentives as a reduction of rental revenue over the 
term of the lease.  

If collectability under a lease is not probable, revenue recognized is limited to the lesser of revenue that would have been 

recognized if collectability was probable or lease payments collected.

We recognize lease revenue associated with tenant expense recoveries in the same periods in which we incur the related 

expenses, including tenant reimbursements of property taxes, utilities and other property operating expenses. 

We recognize fees received for lease terminations as revenue and write off against such revenue any (1) deferred rents 
receivable, and (2) deferred revenue, lease incentives and intangible assets that are amortizable into rental revenue associated 
with the leases; the resulting net amount is the net revenue from the early termination of the leases.  When a tenant’s lease for 
space in a property is terminated early but the tenant continues to lease such space under a new or modified lease in the 
property, the net revenue from the early termination of the lease is recognized evenly over the remaining life of the new or 
modified lease in place on that property.

F-27

Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

Effective January 1, 2019, we adopted guidance issued by the FASB setting forth principles for the recognition, 

measurement, presentation and disclosure of leases, which required lessors of real estate to account for leases using an approach 
substantially equivalent to guidance previously in place for operating leases, direct financing leases and sales-type leases.  We 
adopted this guidance for leases on January 1, 2019 using a modified retrospective transition approach under which we elected 
to not adjust prior comparative reporting periods (except for our presentation of lease revenue discussed below).  We elected to 
apply a package of practical expedients that enabled us to carry forward upon adoption our historical assessments of: expired or 
existing leases regarding their lease classification and deferred recognition of non-incremental direct leasing costs; and whether 
any expired or existing contracts are, or contain, leases.  We also elected a practical expedient that enabled us to avoid the need 
to assess whether expired or existing land easements not previously accounted for as leases are, or contain, a lease.  In addition, 
we elected a practical expedient to avoid separating non-lease components that otherwise would need to be accounted for under 
revenue accounting guidance (such as tenant reimbursements of property operating expenses) from the associated lease 
component since (1) the non-lease components have the same timing and pattern of transfer as the associated lease component 
and (2) the lease component, if accounted for separately, would be classified as an operating lease; this enables us to account for 
the combination of the lease component and non-lease components as an operating lease since the lease component is the 
predominant component of the combined components.  

Construction Contract and Other Service Revenues

We enter into construction contracts to complete various design and construction services primarily for our USG tenants.  

The revenues and expenses from these services consist primarily of subcontracted costs that are reimbursed to us by our 
customers along with a fee.  These services are an ancillary component of our overall operations, with small operating margins 
relative to the revenue.  We review each contract to determine the performance obligations and allocate the transaction price 
based on the standalone selling price, as discussed further below.  We recognize revenue under these contracts as services are 
performed in an amount that reflects the consideration we expect to receive in exchange for those services.  Our performance 
obligations are satisfied over time as work progresses.  Revenue recognition is determined using the input method based on 
costs incurred as of a point in time relative to the total estimated costs at completion to measure progress toward satisfying our 
performance obligations.  We believe incurred costs of work performed best depicts the transfer of control of the services being 
transferred to the customer.  

In determining whether the performance obligations of each construction contract should be accounted for separately 
versus together, we consider numerous factors that may require significant judgment, including: whether the components 
contracted are substantially the same with the same pattern of transfer; whether the customer could contract with another party 
to perform construction based on our design project; and whether the customer can elect not to move forward after the design 
phase of the contract.  Most of our contracts have a single performance obligation as the promise to transfer the services is not 
separately identifiable from other obligations in the contracts and, therefore, are not distinct.  Some contracts have multiple 
performance obligations, most commonly due to having distinct project phases for design and construction for which our 
customer is making decisions and managing separately.  In these cases, we allocate the transaction price between these 
performance obligations based on the relative standalone selling prices, which we determine by evaluating: the relative costs of 
each performance obligation; the expected operating margins (which typically do not vary significantly between obligations); 
and amounts set forth in the contracts for each obligation.  Contract modifications, such as change orders, are routine for our 
construction contracts and are generally determined to be additions to the existing performance obligations because they would 
have been part of the initial performance obligations if they were identified at the initial contract date.  

We have three main types of compensation arrangements for our construction contracts: guaranteed maximum price 

(“GMP”); firm fixed price (“FFP”); and cost-plus fee.  

•

•

GMP contracts provide for revenue equal to costs incurred plus a fee equal to a percentage of such costs, up to a maximum 
contract amount.  We generally enter into GMP contracts for projects that are significant in nature based on the size of the 
project and total fees, and for which the full scope of the project has not been determined as of the contract date.  GMP 
contracts are lower risk to us than FFP contracts since the costs and revenue move proportionately to one another.
FFP contracts provide for revenue equal to a fixed fee.  These contracts are typically lower in value and scope relative to 
GMP contracts, and are generally entered into when the scope of the project is well defined.  Typically, we assume more 
risk with FFP contracts than GMP contracts since the revenue is fixed and we could realize losses or less than expected 
profits if we incur more costs than originally estimated.  However, these types of contracts offer the opportunity for 
additional profits when we complete the work for less than originally estimated. 

F-28

Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

•

Cost-plus fee contracts provide for revenue equal to costs incurred plus a fee equal to a percentage of such costs but, unlike 
GMP contracts, do not have a maximum contract amount.  Similar to GMP contracts, cost-plus fee contracts are low risk to 
us since the costs and revenue move proportionately to one another.

Construction contract cost estimates are based primarily on contracts in place with subcontractors to complete most of the 

work, but may also include assumptions, such as performance of subcontractors and cost and availability of materials, to project 
the outcome of future events over the course of the project.   We review and update these estimates regularly as a significant 
change could affect the profitability of our construction contracts.  We recognize adjustments in estimated profit on contracts 
under the cumulative catch-up method as the modification does not create a new performance obligation.  Under this method, 
the impact of the adjustment on profit recorded to date on a contract is recognized in the period the adjustment is identified.  
Revenue and profit in future periods are recognized using the adjusted estimate.  If at any time the estimate of contract 
profitability indicates an anticipated loss on the contract, we recognize the total loss in the quarter it is identified. 

Our timing of revenue recognition for construction contracts generally differs from the timing of invoicing to customers.  
We recognize such revenue as we satisfy our performance obligations.  Payment terms and conditions vary by contract type.  
Under most of our contracts, we bill customers monthly, as work progresses, in accordance with the contract terms, with 
payment due in 30 days, although customers occasionally pay in advance of services being provided.  We have determined that 
our contracts generally do not include a significant financing component.  The primary purpose of the timing of our invoicing is 
for convenience, not to receive financing from our customers or to provide customers with financing.  Additionally, the timing 
of transfer of the services is often at the discretion of the customer. 

Under most of our contracts, we bill customers one month subsequent to revenue recognition, resulting in contract assets 

representing unbilled construction revenue. 

Our contract liabilities consist of advance payments from our customers or billings in excess of construction contract 

revenue recognized. 

Expense Classification

We classify as property operating expense costs incurred for property taxes, ground rents, utilities, property management, 

insurance, repairs and exterior and interior maintenance, as well as associated labor and indirect costs attributable to these costs.

We classify as general, administrative and leasing expenses costs incurred for corporate-level management, public 
company administration, asset management, leasing, investor relations, marketing and corporate-level insurance (including 
general business and director and officers) and leasing prospects, as well as associated labor and indirect costs attributable to 
these expenses.

Share-Based Compensation

We issue four forms of share-based compensation: restricted COPT common shares (“restricted shares”), deferred share 
awards (also known as restricted share units), performance share units (also known as performance share awards) (“PSUs”) and 
profit interest units (“PIUs”) (time-based and performance-based).  We account for share-based compensation in accordance 
with authoritative guidance provided by the FASB that establishes standards for the accounting for transactions in which an 
entity exchanges its equity instruments for goods or services, focusing primarily on accounting for transactions in which an 
entity obtains employee services in share-based payment transactions.  The guidance requires us to measure the cost of 
employee services received in exchange for an award of equity instruments based generally on the fair value of the award on the 
grant date; such cost is then recognized over the period during which the employee is required to provide service in exchange 
for the award.  No compensation cost is recognized for equity instruments for which employees do not render the requisite 
service.  The guidance also requires that share-based compensation be computed based on awards that are ultimately expected 
to vest; as a result, future forfeitures of awards are estimated at the time of grant and revised, if necessary, in subsequent periods 
if actual forfeitures differ from those estimates.  If an award is voluntarily cancelled by an employee, we recognize the 
previously unrecognized cost associated with the original award on the date of such cancellation.  We capitalize costs associated 
with share-based compensation attributable to employees engaged in development and redevelopment activities.

We compute the fair value of restricted shares, time-based PIUs and deferred share awards based on the fair value of COPT 

common shares on the grant date.  We compute the fair value of PSUs and performance-based PIUs using a Monte Carlo 

F-29

Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

model.  Significant assumptions used for that model include the following: the baseline common share value is the market value 
on the grant date; the risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant; and expected 
volatility is based on historical volatility of COPT’s common shares.

Income Taxes

COPT elected to be treated as a REIT under Sections 856 through 860 of the Internal Revenue Code.  To qualify as a 
REIT, COPT must meet a number of organizational and operational requirements, including a requirement that it distribute at 
least 90% of the Company’s adjusted taxable income to its shareholders.  As a REIT, COPT generally will not be subject to 
Federal income tax on taxable income that it distributes to its shareholders.  If COPT fails to qualify as a REIT in any tax year, 
it will be subject to Federal income tax on its taxable income at regular corporate rates and may not be able to qualify as a REIT 
for four subsequent tax years.

COPLP is a limited partnership and is not subject to federal income tax.  Its partners are required to report their respective 

share of the Operating Partnership’s taxable income on their respective tax returns.  COPT’s share of the Operating 
Partnership’s taxable income is reported on COPT’s income tax return.

For Federal income tax purposes, dividends to shareholders may be characterized as ordinary income, capital gains or 
return of capital.  The characterization of dividends paid on COPT’s common shares during each of the last three years was as 
follows:

Ordinary income
Long-term capital gain
Return of capital

For the Years Ended December 31,

2020

2019

 54.9% 
 —% 

 54.4% 
 45.6% 
 —% 

 83.1% 
 —% 
 16.9% 

The dividends allocated to each of the above years for Federal income tax purposes included dividends paid on COPT’s 
common shares during each of those years except for the dividends paid on January 15, 2021 and 2020 (with a record date of 
December 31, 2020 and 2019, respectively), which were allocated for Federal income tax purposes to 2020 and 2019, 
respectively.

We distributed all of COPT’s REIT taxable income in 2020, 2019 and 2018 and, as a result, did not incur Federal income 

tax in those years. 

The net basis of our consolidated assets and liabilities for tax reporting purposes was approximately $10 million higher 

than the amount reported on our consolidated balance sheet as of December 31, 2020.

We are subject to certain state and local income and franchise taxes.  The expense associated with these state and local 
taxes is included in general and administrative expense and property operating expenses on our consolidated statements of 
operations.  We did not separately state these amounts on our consolidated statements of operations because they are 
insignificant.  

Reclassifications

We reclassified certain amounts from prior periods to conform to the current period presentation of our consolidated 

financial statements with no effect on previously reported net income or equity.

Recent Accounting Pronouncements

As discussed above, effective January 1, 2020, we adopted guidance issued by the FASB that changed how entities 

measure credit losses for most financial assets and certain other instruments not measured at fair value through net income.  The 
guidance replaced the current incurred loss model with an expected loss approach, resulting in a more timely recognition of 
such losses.  The guidance applies to most financial assets measured at amortized cost and certain other instruments, including 
trade and other receivables (excluding those arising from operating leases), loans, held-to-maturity debt securities, net 
investments in leases and off-balance-sheet credit exposures.  Under this guidance, we recognize an estimate of our expected 

F-30

Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

credit losses on these asset types as an allowance, as the guidance requires that financial assets be measured on an amortized 
cost basis and be presented at the net amount expected to be collected.  We adopted this guidance using the modified 
retrospective transition method under which we recognized a $5.5 million allowance for credit losses by means of a cumulative-
effect adjustment to cumulative distributions in excess of net income of the Company (or common units of the Operating 
Partnership), and did not adjust prior comparative reporting periods.  Our consolidated statements of operations reflect 
adjustments for changes in our expected credit losses occurring subsequent to adoption of this guidance.

Effective January 1, 2020, we adopted guidance issued by the FASB that modifies disclosure requirements for fair value 

measurements.  The resulting changes in disclosure did not have a material impact on our consolidated financial statements.

Effective January 1, 2020, we adopted guidance issued by the FASB that 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.  FASB guidance did not previously address the 
accounting for such implementation costs.  Our adoption of this guidance did not have a material impact on our consolidated 
financial statements.

In March 2020, the FASB issued guidance containing practical expedients for reference rate reform related activities 
pertaining to debt, leases, derivatives and other contracts.  The guidance is optional and may be adopted over time as reference 
rate reform activities occur.  During 2020, we elected to apply an expedient to treat any changes in loans resulting from 
reference rate reform as debt modifications (as opposed to extinguishments) and hedge accounting expedients related to 
probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which 
future hedged transactions will be based matches the index on the corresponding derivatives.  Application of the hedge 
accounting expedients preserves the presentation of derivatives consistent with past presentation.  We will continue to evaluate 
the impact of this guidance and may apply other elections as applicable as additional changes in the market occur. 

In April 2020, the FASB issued a Staff Q&A document that addressed the accounting for lease accounting guidance for 

lease concessions resulting from the COVID-19 pandemic.  Under existing lease guidance, we would normally 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 
as a lease modification) or if such a concession was implemented pursuant to enforceable rights and obligations within the 
existing lease agreement (and, therefore, not treated as a lease modification).  The Staff Q&A document enabled us to bypass 
the lease-by-lease analysis for lease concessions resulting from the COVID-19 pandemic, and instead elect to either apply the 
lease modification accounting framework or not, with such elections applied consistently to leases with similar characteristics 
and similar circumstances.  Entities may make the elections for any lessor-provided concessions related to the effects of the 
COVID-19 pandemic (such as deferrals of lease payments or reduced future lease payments) as long as the concession does not 
result in a substantial increase in the rights of the lessor or the obligations of the lessee.  We chose to apply the elections 
available under the Staff Q&A to restructurings of lease payment terms granted by us to tenants, the effect of which did not 
have a material impact on our consolidated financial statements.

Fair Value Measurements

Accounting standards define fair value as the exit price, or the amount that would be received upon sale of an asset or paid 

to transfer a liability in an orderly transaction between market participants as of the measurement date.  The standards also 
establish a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use 
of unobservable inputs by requiring that the most observable inputs be used when available.  Observable inputs are inputs 
market participants would use in valuing the asset or liability developed based on market data obtained from sources 
independent of us.  Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use 
in valuing the asset or liability developed based upon the best information available in the circumstances.  The hierarchy of 
these inputs is broken down into three levels: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets 
or liabilities; Level 2 inputs include (1) quoted prices for similar assets or liabilities in active markets, (2) quoted prices for 
identical or similar assets or liabilities in inactive markets and (3) inputs (other than quoted prices) that are observable for the 
asset or liability, either directly or indirectly; and Level 3 inputs are unobservable inputs for the asset or liability.  
Categorization within the valuation hierarchy is based upon the lowest level of input that is most significant to the fair value 
measurement.

Recurring Fair Value Measurements 

COPT has a non-qualified elective deferred compensation plan for Trustees and certain members of our management team 

that, prior to December 31, 2019, permitted participants to defer up to 100% of their compensation on a pre-tax basis and 
receive a tax-deferred return on such deferrals.  The Company froze additional entry into the plan effective December 31, 2019. 
The assets held in the plan (comprised primarily of mutual funds and equity securities) and the corresponding liability to the 
participants are measured at fair value on a recurring basis on COPT’s consolidated balance sheets using quoted market prices, 
as are other marketable securities that we hold.  The balance of the plan, which was fully funded, totaled $3.0 million as of 
December 31, 2020 and $3.1 million as of December 31, 2019, and is included in the line entitled “prepaid expenses and other 
assets, net” on COPT’s consolidated balance sheets along with an insignificant amount of other marketable securities.  The 
offsetting liability associated with the plan is adjusted to fair value at the end of each accounting period based on the fair value 
of the plan assets and reported in “other liabilities” on COPT’s consolidated balance sheets.  The assets of the plan are classified 
in Level 1 of the fair value hierarchy, while the offsetting liability is classified in Level 2 of the fair value hierarchy.

The fair values of our interest rate derivatives are determined using widely accepted valuation techniques, including a 
discounted cash flow analysis on the expected cash flows of each derivative.  This analysis reflects the contractual terms of the 
derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate market data and 
implied volatilities in such interest rates.  While we determined that the majority of the inputs used to value our derivatives fall 
within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our interest rate derivatives utilize 
Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default.  However, as of December 31, 
2020 and 2019, we assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our 
derivatives and determined that these adjustments are not significant.  As a result, we determined that our interest rate derivative 
valuations in their entirety are classified in Level 2 of the fair value hierarchy.

The carrying values of cash and cash equivalents, restricted cash, accounts receivable, other assets (excluding investing 

receivables) and accounts payable and accrued expenses are reasonable estimates of their fair values because of the short 
maturities of these instruments.  The fair values of our investing receivables, as disclosed in Note 8, were based on the 
discounted estimated future cash flows of the loans (categorized within Level 3 of the fair value hierarchy); the discount rates 
used approximate current market rates for loans with similar maturities and credit quality, and the estimated cash payments 
include scheduled principal and interest payments.  For our disclosure of debt fair values in Note 10, we estimated the fair value 
of our unsecured senior notes based on quoted market rates for publicly-traded debt (categorized within Level 2 of the fair value 
hierarchy) and estimated the fair value of our other debt based on the discounted estimated future cash payments to be made on 
such debt (categorized within Level 3 of the fair value hierarchy); the discount rates used approximate current market rates for 
loans, or groups of loans, with similar maturities and credit quality, and the estimated future payments include scheduled 
principal and interest payments.  Fair value estimates are made as of a specific point in time, are subjective in nature and 
involve uncertainties and matters of significant judgment.

For additional fair value information, refer to Note 8 for investing receivables, Note 10 for debt and Note 11 for interest 

rate derivatives.

2019 Nonrecurring Fair Value Measurements

In the third quarter of 2019, we determined that the carrying amount of land held in Frederick, Maryland would not be 
recovered from its eventual disposition.  As a result, we recognized an impairment loss of $327,000 in order to adjust the land 
to its estimated fair value.  This land was sold in the fourth quarter of 2019.

2020 Development Activities

In 2020, we placed into service 1.8 million square feet in 11 newly-developed properties, 42,000 square feet in expansions 

of three fully-operational properties and 21,000 square feet in a redeveloped property.  As of December 31, 2020, we had 11 
properties under development, including three partially-operational properties, that we estimate will total 1.5 million square feet 
upon completion.

In the third quarter of 2020, we concluded that we no longer expected to develop a property in Baltimore, Maryland.  As a 

result, we recognized an impairment loss on previously incurred pre-development costs of $1.5 million.

2019 Dispositions

In 2019, we sold, through a series of transactions, a 90% interest in nine data center shells in Northern Virginia based on an 

aggregate property value of $345.1 million, retaining a 10% interest in the properties through BREIT COPT DC JV LLC 
(“BREIT-COPT”), a newly-formed joint venture.  The transactions for seven of these properties were completed on June 20, 
2019 and the remaining two properties on December 5, 2019.  Our partner in the joint venture acquired the 90% interest from us 
for $310.6 million.  We account for our interest in the joint venture using the equity method of accounting as described further 
in Note 6.  We recognized a gain on sale of $105.2 million.

2019 Development Activities

In 2019, we placed into service 1.1 million square feet in nine newly-developed properties and 85,000 square feet in one 

property under redevelopment. 

2018 Dispositions

In 2018, we sold 11751 Meadowville Lane, an operating property totaling 193,000 square feet in Chester, Virginia (in our 
Data Center Shells sub-segment).  We contractually closed on the sale of this property on October 27, 2017 for $44.0 million.  
We provided a financial guaranty to the buyer under which we provided an indemnification for up to $20 million in losses it 
could incur related to a potential defined capital event occurring on the property; our financial guaranty to the buyer expired on 
October 1, 2018, resulting in no losses to us.  We accounted for this transaction as a financing arrangement.  Accordingly, we 
did not recognize the sale of this property for accounting purposes until the expiration of the guaranty on October 1, 2018.  In 
the fourth quarter of 2018, we recognized a gain on this sale of $1.5 million. 

2018 Development Activities

In 2018, we placed into service 666,000 square feet in six newly-developed properties, 22,000 square feet in one 

redeveloped property and land under a long-term contract.

In the fourth quarter of 2018, we abandoned plans to redevelop a property in our Fort Meade/BW Corridor sub-segment 
after we completed leasing on the property that did not require any redevelopment.  Accordingly, we recognized an impairment 
loss of $2.4 million representing pre-development costs associated with the property.

Leases

Lessor Arrangements

We lease real estate properties, comprised primarily of office properties and data center shells, to third parties.  As of 
December 31, 2020, these leases, which may encompass all, or a portion of, a property, had remaining terms spanning from one 
month to 18 years and averaging approximately 5.4 years.

Our lease revenue is comprised of: fixed lease revenue, including contractual rent billings under leases recognized on a 
straight-line basis over lease terms and amortization of lease incentives and above- and below- market lease intangibles; and 
variable lease revenue, including tenant expense recoveries, lease termination revenue and other revenue from tenants that is not 
fixed under the lease.  The table below sets forth our composition of lease revenue recognized between fixed and variable lease

significantly impact their activities, including development, leasing and management of the properties developed by the VIEs; 
and (2) right to receive returns on our fundings and, in many cases, the obligation to fund the activities of the ventures to the 
extent that third-party financing is not obtained, both of which could be potentially significant to the VIEs.

Each of these joint ventures are engaged in the development and operation of real estate.  With regard to these joint ventures:

•

for LW Redstone Company, LLC, we anticipate funding certain infrastructure costs (up to a maximum of $76.0 million
excluding accrued interest thereon) due to be reimbursed by the City of Huntsville as discussed further in Note 8.  We had 
advanced $61.0 million to the City through December 31, 2020 to fund such costs.  We also expect to fund additional 
development costs through equity contributions to the extent that third party financing is not obtained.  Our partner was 
credited with a $9.0 million in invested capital upon formation and is not required to make, nor has it made, additional 
equity contributions.  In March 2020, the LW Redstone Company, LLC joint venture agreement was amended to change 
the distribution terms to allow the venture to distribute financing proceeds to satisfy our partner’s cumulative preferred 
return and to provide our partner a priority preferred return on its invested capital.  While net cash flow distributions to the 
partners vary depending on the source of the funds distributed, cash flows are generally distributed to the partners as 
follows: (1) cumulative preferred returns of 13.5% on our partner’s invested capital; (2) cumulative preferred returns of 
13.5% on our invested capital; (3) return of our invested capital; (4) return of our partner’s invested capital; and (5) any 
remaining residual 85% to us and 15% to our partner.  Our partner has the right to require us to acquire its interest for fair 
value; accordingly, we classify the fair value of our partner’s interest as redeemable noncontrolling interests in the 
mezzanine section of our consolidated balance sheets.  We have the right to acquire our partner’s interest at fair value upon 
the earlier of five years following the project’s achievement of a construction commencement threshold of 4.4 million
square feet or March 2040; the project had achieved approximately 1.6 million square feet of construction commencement

through December 31, 2020.  Our partner has the right to receive some or all of the consideration for the acquisition of its 
interests in the form of common units in COPLP;
for Stevens Investors, LLC, net cash flows of this entity will be distributed to the partners as follows: (1) member loans and 
accrued interest; (2) pro rata return of the partners’ capital; (3) pro rata return of the partners’ respective unpaid preferred 
returns; and (4) varying splits of 85% to 60% to us and the balance to our partners as we reach specified return hurdles.  
Our partners have the right to require us to acquire some or all of their interests for fair value for a defined period of time 
following the property’s development completion (expected to occur in 2021) and stabilization (as defined in the operating 
agreement) of the joint venture’s office property; accordingly, we classify the fair value of our partners’ interest as 
redeemable noncontrolling interests in the mezzanine section of our consolidated balance sheets.  We and our partners each 
have the right to acquire each other’s interests at fair value upon the second anniversary of the property’s stabilization date 
(as defined in the operating agreement).  Our partners have the right to receive some or all of the consideration for the 
acquisition of their interests in the form of common units in COPLP; and
for M Square Associates, LLC, net cash flows of this entity are distributed to the partners as follows: (1) member loans and 
accrued interest; (2) our preferred return and capital contributions used to fund infrastructure costs; (3) the partners’ 
preferred returns and capital contributions used to fund all other costs, including the base land value credit, in proportion to 
the accrued returns and capital accounts; and (4) residual amounts distributed 50% to each member.

We disclose the activity of our redeemable noncontrolling interests in Note 12.  

The ventures discussed above include only ones in which parties other than COPLP and COPT own interests.

(1) Included in the line entitled “investment in unconsolidated real estate joint ventures” on our consolidated balance sheets.
(2) As of December 31, 2020, our investment in B RE COPT was $7.4 million lower than our share of the joint venture’s equity due to a 

difference between our cost basis and our share of B RE COPT’s underlying equity in the net assets acquired from GI-COPT.

These joint ventures operate triple-net leased, single-tenant data center shell properties in Northern Virginia.  With regard to 
these joint ventures:

•

•

•

B RE COPT was formed in 2020, when, as described further in Note 4, we sold a 90% interest in two properties and 
retained a 10% interest in the properties through B RE COPT;
on December 22, 2020, we sold, through a series of transactions, 80% of our 50% interests in LLCs holding six properties 
and associated mortgage debt that we owned through GI-COPT DC Partnership LLC (“GI-COPT”).  We received 
$60 million in proceeds and a 10% retained interest in the LLCs through B RE COPT, and recognized a gain of 
$29.4 million on the sale of these interests.  GI-COPT was dissolved upon completion of these transactions; and
BREIT-COPT was formed in 2019, when, as described further in Note 4, we sold a 90% interest in nine properties and 
retained a 10% interest in the properties through the joint venture; 

We concluded that B RE COPT and BREIT-COPT are variable interest entities.  Under the terms of the joint venture 
agreements, we and our partners receive returns in proportion to our investments, and our maximum exposure to losses is 
limited to our investments, subject to certain indemnification obligations with respect to nonrecourse debt secured by the 
properties.  The nature of our involvement in the activities of the joint venture does not give us power over decisions that 
significantly affect its economic performance.

Our notes receivable from the City of Huntsville funded infrastructure costs in connection with our LW Redstone 

Company, LLC joint venture (see Note 6) and carry an interest rate of 9.95%.  These notes and the accrued and unpaid interest 
thereon, which is compounded annually on March 1, will be repaid using the real estate taxes generated by the properties 
developed by the joint venture.  When these tax revenues are sufficient to cover the debt service on a certain increment of 
municipal bonds, the City of Huntsville will be required to issue bonds to repay the notes and the accrued and unpaid interest 
thereon.  Each note has a maturity date of the earlier of 30 years from the date issued or the expiration of the tax increment 
district comprising the developed properties in 2045.  

Our other investing loans receivable carry an interest rate of 8.0% and mature in 2021.  

The fair value of these receivables was approximately $73 million as of December 31, 2020 and $74 million as of 

December 31, 2019.

An increase or decrease in the valuation allowance resulting from a change in circumstances that causes a change in our

On October 10, 2018, we entered into a credit agreement with a group of lenders to replace our existing unsecured 
revolving credit facility with a new facility (the prior facility and new facility are referred to collectively herein as our 
“Revolving Credit Facility”).  The lenders’ aggregate commitment under the facility is $800.0 million, with the ability for us to 
increase the lenders’ aggregate commitment to $1.25 billion, provided that there is no default under the facility and subject to 
the approval of the lenders.  The facility matures on March 10, 2023, with the ability for us to further extend such maturity 
by two six-month periods at our option, provided that there is no default under the facility and we pay an extension fee 
of 0.075% of the total availability under the facility for each extension period.  The interest rate on the facility is based on 
LIBOR plus 0.775% to 1.450%, as determined by the credit ratings assigned to COPLP by Standard & Poor’s Ratings Services, 
Moody’s Investors Service, Inc. or Fitch Ratings Ltd. (collectively, the “Ratings Agencies”).  The facility also carries a 
quarterly fee that is based on the lenders’ aggregate commitment under the facility multiplied by a per annum rate 
of 0.125% to 0.300%, as determined by the credit ratings assigned to COPLP by the Ratings Agencies.  As of December 31, 
2020, the maximum borrowing capacity under this facility totaled $800.0 million, of which $657.0 million was available.

Weighted average borrowings under our Revolving Credit Facility totaled $204.9 million in 2020 and $255.6 million in 

2019.  The weighted average interest rate on our Revolving Credit Facility was 1.55% in 2020 and 3.32% in 2019.

Term Loan Facilities

As of December 31, 2020, we had an unsecured term loan facility that we amended in 2020 to increase the loan amount by 
$150.0 million and change the interest terms.  The loan carries a variable interest rate based on the LIBOR rate (customarily the 
30-day rate) plus 1.00% to 1.65%, as determined by: a ratio of our debt to our assets; and the credit ratings assigned to COPLP 
by the Ratings Agencies.

Notes to Consolidated Financial Statements (Continued)

In addition to the term loan discussed above, we also had a term loan for which we repaid the remaining balance of $100.0 

million in 2018.

In connection with our Revolving Credit Facility discussed above, we have the ability to borrow up to $500.0 million under 
new term loans from the facility’s lender group provided that there is no default under the facility and subject to the approval of 
the lenders.

Unsecured Senior Notes

On September 17, 2020, we issued $400.0 million of 2.25% Senior Notes due 2026 (the “2.25% Notes”) at an initial 
offering price of 99.416% of their face value.  The proceeds from this issuance, after deducting underwriting discounts, but 
before other offering expenses, were $395.3 million.  The notes mature on March 15, 2026.  The effective interest rate under the 
notes, including amortization of discount and issuance costs, was 2.48%.

With regard to our 3.70% Senior Notes, we:

•

•

purchased $122.9 million of our 3.70% Senior Notes due 2021 (the “3.70% Notes”) on September 17, 2020 for $126.0 
million, plus accrued interest, pursuant to a tender offer; and  
redeemed the remaining $177.1 million of the 3.70% Notes on October 19, 2020 for $180.9 million plus accrued interest.  

In connection with this purchase and redemption, we recognized a loss on early extinguishment of debt of $7.3 million in 2020.  

We may redeem our unsecured senior notes, in whole at any time or in part from time to time, at our option, at a 

redemption price equal to the greater of (1) the aggregate principal amount of the notes being redeemed or (2) the sum of the 
present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such 
payments of interest accrued as of the date of redemption) discounted to its present value, on a semi-annual basis at an adjusted 
treasury rate plus a spread (30 basis points for the 3.60% Senior Notes, 40 basis points for the 5.25% Senior Notes, 45 basis 
points for the 5.00% Senior Notes and 35 basis points for the 2.25% Senior Notes), plus, in each case, accrued and unpaid 
interest thereon to the date of redemption.  However, in each case, if this redemption occurs on or after a defined period of time 
prior to the maturity date (one month for the 2.25% Notes or three months for the other notes), the redemption price will be 
equal to 100% of the principal amount of the notes being redeemed, plus accrued and unpaid interest thereon to, but not 
including, the applicable redemption date.  These notes are unconditionally guaranteed by COPT.

As described further in Note 10, in September 2020, we completed our issuance of the 2.25% Notes.  In August 2020, in 
anticipation of pursuing such an issuance, we determined that the forecasted transactions hedged by our three interest rate swaps 
with an effective date of June 30, 2020 and an aggregate notional amount of $225.0 million were no longer probable of 
occurring, resulting in our discontinuance of hedge accounting on these swaps.  When we consummated the note issuance in 
September 2020, we determined that it was probable that the forecasted transactions would not occur, resulting in our 
reclassification of $51.9 million in losses from AOCL to loss on interest rate derivatives on our statements of operations.  On 
September 22, 2020, we cash settled these swaps and accrued interest thereon for an aggregate amount of $53.1 million.

Based on the fair value of our derivatives as of December 31, 2020, we estimate that approximately $4.8 million of losses 

will be reclassified from AOCL as an increase to interest expense over the next 12 months.

We have agreements with each of our interest rate derivative counterparties that contain provisions under which, if we 
default or are capable of being declared in default on defined levels of our indebtedness, we could also be declared in default on 
our derivative obligations.  Failure to comply with the loan covenant provisions could result in our being declared in default on 
any derivative instrument obligations covered by the agreements.  As of December 31, 2020, we were not in default with any of 
these provisions.  As of December 31, 2020, the fair value of interest rate derivatives in a liability position related to these 
agreements was $9.6 million, excluding the effects of accrued interest and credit valuation adjustments.  As of December 31, 
2020, we had not posted any collateral related to these agreements.  If we breach any of these provisions, we could be required 
to settle our obligations under the agreements at their termination value, which was $10.0 million as of December 31, 2020.

Redeemable Noncontrolling Interests

We determine the fair value of the interests based on unobservable inputs after considering the assumptions that market 
participants would make in pricing the interest.  We apply a discount rate to the estimated future cash flows allocable to our 
partners from the properties underlying the respective joint ventures.  Estimated cash flows used in such analyses are based on 
our plans for the properties and our views of market and economic conditions, and consider items such as current and future 
rental rates, occupancy projections and estimated operating and development expenditures.

Equity - COPT and Subsidiaries

Preferred Shares

As of December 31, 2020, COPT had 25.0 million preferred shares authorized and unissued at $0.01 par value per share.  

Common Shares

In November 2018, COPT established an at-the-market (“ATM”) stock offering program under which it may offer and sell 
common shares in at-the-market stock offerings having an aggregate gross sales price of up to $300.0 million (the “2018 ATM 
Program”).  Under the 2018 ATM Program, COPT may also, at its discretion, sell common shares under forward equity sales 
agreements.  As of December 31, 2020, COPT had not issued any shares under the 2018 ATM Program.

From 2018 to 2020, COPT completed the following share issuances under stock programs no longer in effect:

•

•

1.6 million shares in 2019 for net proceeds of $46.5 million, and 5.9 million shares in 2018 for net proceeds of $172.5 
million, under forward equity sale agreements originating on November 2, 2017 to issue shares at an initial gross offering 
price of $31.00 per share, before underwriting discounts, commissions and offering expenses.  The forward sale price 
received upon physical settlement of the agreements was subject to adjustment on a daily basis based on a floating interest 
rate factor equal to the overnight bank funding rate less a spread, and was decreased on each of certain dates specified in 
the agreements during the term of the agreements; and
992,000 common shares in 2018 at a weighted average price of $30.46 per share under an ATM program established in 
2016.  Net proceeds from the shares issued totaled $29.8 million, after payment of $0.5 million in commissions to sales 
agents.

COPT contributed the net proceeds from these issuances to COPLP in exchange for an equal number of units in COPLP. 

Certain holders of COPLP common units converted their units into COPT common shares on the basis of one common 

share for each common unit in the amount of 14,009 in 2020, 105,039 in 2019 and 1.9 million in 2018.

COPT declared dividends per common share of $1.10 in 2020, 2019 and 2018.

COPT pays dividends at the discretion of its Board of Trustees.  COPT’s ability to pay cash dividends will be dependent 
upon: (1) the cash flow generated from our operations; (2) cash generated or used by our financing and investing activities; and 
(3) the annual distribution requirements under the REIT provisions of the Code described in Note 2 and such other factors as 
the Board of Trustees deems relevant.  COPT’s ability to make cash dividends will also be limited by the terms of COPLP’s 
Partnership Agreement, as well as by limitations imposed by state law.  In addition, COPT is prohibited from paying cash 
dividends in excess of the amount necessary for it to qualify for taxation as a REIT if a default or event of default exists 

F-46

 
 
 
 
 
 
 
 
 
 
Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

pursuant to the terms of our Revolving Credit Facility; this restriction does not currently limit COPT’s ability to pay dividends, 
and COPT does not believe that this restriction is reasonably likely to limit its ability to pay future dividends because it expects 
to comply with the terms of our Revolving Credit Facility.

See Note 15 for disclosure of common share activity pertaining to our share-based compensation plans.

Equity - COPLP and Subsidiaries

Limited Partner Preferred Units 

On December 21, 2020, COPLP redeemed its 352,000 Series I Preferred Units from the third party unitholder at the units’ 
aggregate liquidation preference of $8.8 million ($25.00 per unit), plus accrued and unpaid distributions of return thereon up to 
the date of redemption.  The owner of these units earned a priority annual cumulative return on the units equal to: 3.5% of their 
liquidation preference from September 23, 2019 up to the redemption date; and 7.5% of their liquidation preference prior to 
September 23, 2019.  These units were convertible into common units on the basis of 0.5 common units for each Series I 
Preferred Unit, with the resulting common units being exchangeable for COPT common shares in accordance with the terms of 
COPLP’s agreement of limited partnership. 

Common Units 

COPT owned 98.6% of COPLP’s common units as of December 31, 2020 and 98.7% as of December 31, 2019. 

From 2018 to 2020, COPT acquired additional common units through the following common share issuances under stock 

programs no longer in effect:

•

•

1.6 million shares in 2019 for net proceeds of $46.5 million, and 5.9 million shares in 2018 for net proceeds of $172.5 
million, under forward equity sale agreements originating on November 2, 2017; and
992,000 shares in 2018 at a weighted average price of $30.46 per share under an ATM program established in 2016.  Net 
proceeds from the shares issued totaled $29.8 million, after payment of $0.5 million in commissions to sales agents.

Limited partners in COPLP holding common units have the right to require COPLP to redeem all or a portion of their 
common units.  COPLP (or COPT as the general partner) has the right, in its sole discretion, to deliver to such redeeming 
limited partners for each partnership unit either one COPT common share (subject to anti-dilution adjustment) or a cash 
payment equal to the then fair market value of such share (so adjusted) (based on the formula for determining such value set 
forth in the partnership agreement).  Certain limited partners holding common units redeemed their units into common shares 
on the basis of one common share for each common unit in the amount of 14,009 in 2020, 105,039 in 2019 and 1.9 million in 
2018.  In addition, we redeemed 924 common units in 2019 for $25,000 and 13,377 in 2018 for $339,000.

COPLP declared distributions per common unit of $1.10 in 2020, 2019 and 2018.

15. 

Share-Based Compensation and Other Compensation Matters

Share-Based Compensation Plans

In May 2017, COPT adopted the 2017 Omnibus Equity and Incentive Plan (the “2017 Plan”) following the approval of 
such plan by our common shareholders.  COPT may issue equity-based awards under this plan to officers, employees, non-
employee trustees and any other key persons of us and our subsidiaries, as defined in the plan.  The plan provides for a 
maximum of 3.4 million common shares in COPT to be issued in the form of options, share appreciation rights, restricted share 
unit awards, restricted share awards, unrestricted share awards, dividend equivalent rights and other equity-based awards and 
for the granting of cash-based awards.  In November 2018, we amended the 2017 Plan to provide for the future grant of awards 
in the form of PIUs; PIUs are a special class of common unit structured to qualify as “profit interests” for tax purposes which 
are similar to restricted shares and PSUs, except that upon vesting recipients will receive common units in COPLP.  This plan 
expires on May 11, 2027.  Shares for the 2017 Plan are issued under a registration statement on Form S-8 that became effective 
upon filing with the Securities and Exchange Commission.  In connection with awards of common shares granted by COPT 
under the 2017 Plan, COPLP issues to COPT an equal number of equity instruments with identical terms.

PIUs

Commencing in 2019, we offered our executives and Trustees the opportunity to select PIUs as a form of long-term 
compensation in lieu of, or in combination with, other forms of share-based compensation awards (restricted shares, deferred 
share awards and PSUs).  Our executives and certain of our Trustees selected PIUs as their form of share-based compensation 
for their 2019 and 2020 grants.  We granted two forms of PIUs: TB-PIUs; and PB-PIUs.  TB-PIUs are subject to forfeiture 
restrictions until the end of the requisite service period, at which time the TB-PIUs automatically convert into vested PIUs.  PB-
PIUs are subject to a market condition in that the number of earned awards are determined at the end of the performance period 
(as described further below) and then settled in vested PIUs.  Vested PIUs carry substantially the same rights to redemption and 
distributions as non-PIU common units.

TB-PIUs

 TB-PIUs granted to executives vest based on increments and over periods of time set forth under the terms of the 

respective awards provided that the employee remains employed by us.  TB-PIUs granted to non-employee Trustees vest on the 
first anniversary of the grant date, provided that the Trustee remains in his or her position.  Prior to vesting, TB-PIUs carry 
substantially the same rights to distributions as non-PIU common units but carry no redemption rights.  The following table 
summarizes TB-PIUs under the share-based compensation plan for 2019 and  2020:

performance period will be determined based on the percentile rank of COPT’s total shareholder return (“TSR”) relative to a 
peer group of companies, as set forth in the following schedule:

Percentile Rank
75th or greater

Below 25th

Earned Awards Payout %
100% of PB-PIUs granted
50% of PB-PIUs granted
25% of PB-PIUs granted
0% of PB-PIUs granted

If the percentile rank exceeds the 25th percentile and is between two of the percentile ranks set forth in the table above, then the 
percentage of the earned awards will be interpolated between the ranges set forth in the table above to reflect any performance 
between the listed percentiles.  If COPT’s TSR during the measurement period is negative, the maximum number of earned 
awards will be limited to the target level payout percentage.  During the performance period, PB-PIUs carry rights to 
distributions equal to 10% of the distribution rights of non-PIU common units but carry no redemption rights.  

At the end of the performance period, we will settle the award by issuing vested PIUs equal to the number of earned awards 
in settlement of the award plan and paying cash equal to the excess, if any, of: the aggregate distributions that would have been 
paid with respect to vested PIUs issued in settlement of the earned awards through the date of settlement had such vested PIUs 
been issued on the grant date; over the aggregate distributions made on the PB-PIUs during the performance period.  If a 
performance period ends due to a sale event or qualified termination, the number of earned awards is prorated based on the 
portion of the three-year performance period that has elapsed.  If employment is terminated by the employee or by us for cause, 
all PB-PIUs are forfeited. 

We computed grant date fair values for PB-PIUs using Monte Carlo models and are recognizing these values over the 
respective performance periods.  The grant date fair value and certain of the assumptions used in the Monte Carlo models for

equal to the number of earned PSUs in settlement of the award plan and either:

•

•

for awards granted January 1, 2017 and prior thereto, issuing fully-vested COPT shares equal to the aggregate dividends 
that would have been paid with respect to the common shares issued in settlement of the earned PSUs through the date of 
settlement had such shares been issued on the grant date, divided by the share price on such settlement date, as defined 
under the terms of the agreement; or
for awards issued subsequent to January 1, 2017, paying cash equal to the aggregate dividends that would have been paid 
with respect to the common shares issued in settlement of the earned PSUs through the date of settlement had such shares 
been issued on the grant date.

If a performance period ends due to a sale event or qualified termination, the number of earned PSUs was prorated based on the 
portion of the three-year performance period that had elapsed.  If employment was terminated by the employee or by us for 
cause, all PSUs were forfeited.  PSUs do not carry voting rights.

Based on COPT’s TSR relative to its peer group of companies:

•

•

•

for the 2016 PSUs issued to executives that vested on December 31, 2018, we issued 44,757 common shares in settlement 
of the PSUs on January 18, 2019;
for the 2017 PSUs issued to executives that vested on December 31, 2019, we issued 23,181 common shares in settlement 
of the PSUs on January 13, 2020; and
for the 2018 PSUs issued to executives that vested on December 31, 2020, we issued 93,824 common shares in settlement 
of the PSUs on February 3, 2021.

We computed grant date fair values for PSUs using Monte Carlo models and recognized these values over the performance 

periods.  The 2018 grant date fair value of $31.97 was computed using a Monte Carlo model that included the following 
assumptions: baseline common share value of $29.20; expected volatility for common shares of 17.0%; and a risk-free interest 
rate of 2.04%.  

Deferred Share Awards

We made the following grants of deferred share awards to nonemployee members of our Board of Trustees in 2018, 2019

Our investment grade credit risk classification represents entities with investment grade credit ratings from ratings agencies 
(such as Standard & Poor’s Ratings Services, Moody’s Investors Service, Inc. or Fitch Ratings Ltd.), meaning that they are 
considered to have at least an adequate capacity to meet their financial commitments, with credit risk ranging from minimal to 
moderate.  Our non-investment grade credit risk classification represents entities with either no credit agency credit ratings or 
ratings deemed to be sub-investment grade; we believe that there is significantly more credit risk associated with this 
classification.  The credit risk classifications of our investing receivables and tenant notes receivable were last updated in 
December 2020.

An insignificant portion of the investing and tenant notes receivables set forth above was past due, which we define as 

being delinquent by more than three months from the due date.

Information by Business Segment

We have the following reportable segments: Defense/IT Locations; Regional Office; Wholesale Data Center; and Other.  
We also report on Defense/IT Locations sub-segments, which include the following: Fort George G. Meade and the Baltimore/
Washington Corridor (“Fort Meade/BW Corridor”); Northern Virginia Defense/IT Locations; Lackland Air Force Base (in San 
Antonio); locations serving the U.S. Navy (“Navy Support Locations”), which included properties proximate to the Washington 
Navy Yard, the Naval Air Station Patuxent River in Maryland and the Naval Surface Warfare Center Dahlgren Division in 
Virginia; Redstone Arsenal (in Huntsville); and data center shells (properties leased to tenants to be operated as data centers in 
which the tenants fund the costs for the power, fiber connectivity and data center infrastructure).  

We measure the performance of our segments through the measure we define as net operating income from real estate 
operations (“NOI from real estate operations”), which includes: real estate revenues and property operating expenses; and the 
net of revenues and property operating expenses of real estate operations owned through unconsolidated real estate joint 
ventures (“UJVs”) that is allocable to COPT’s ownership interest (“UJV NOI allocable to COPT”).  Amounts reported for 
segment assets represent long-lived assets associated with consolidated operating properties (including the carrying value of 
properties, right-of-use assets, net of related lease liabilities, intangible assets, deferred leasing costs, deferred rents receivable 
and lease incentives) and the carrying value of investments in UJVs owning operating properties.  Amounts reported as 
additions to long-lived assets represent additions to existing consolidated operating properties, excluding transfers from non-
operating properties, which we report separately.

As previously discussed, we provide real estate services such as property management, development and construction 

services primarily for our properties but also for third parties.  The primary manner in which we evaluate the operating 
performance of our service activities is through a measure we define as net operating income from service operations (“NOI 
from service operations”), which is based on the net of revenues and expenses from these activities.  Construction contract and 
other service revenues and expenses consist primarily of subcontracted costs that are reimbursed to us by the customer along 
with a management fee. The operating margins from these activities are small relative to the revenue.  We believe NOI from 
service operations is a useful measure in assessing both our level of activity and our profitability in conducting such operations. 
The table below sets forth the computation of our NOI from service operations (in thousands):

on sales of real estate, gain on sale of investment in unconsolidated real estate joint venture, loss on early extinguishment of 
debt, loss on interest rate derivatives and equity in income of unconsolidated entities not included in NOI to our real estate 
segments since they are not included in the measure of segment profit reviewed by management.  We also did not allocate 
general, administrative and leasing expenses, business development expenses and land carry costs, interest and other income, 
credit loss recoveries (expense), income taxes and noncontrolling interests because these items represent general corporate or

We derived 55% of our construction contract revenue from the USG in 2020, 74% in 2019 and 95% in 2018.

We recognized an insignificant amount of revenue in 2020, 2019 and 2018 from performance obligations satisfied (or 

partially satisfied) in previous periods.

Accounts receivable related to our construction contract services is included in accounts receivable, net on our consolidated

Revenue allocated to the remaining performance obligations under existing contracts as of December 31, 2020 that will be 

recognized as revenue in future periods was $81.9 million, all of which we expect to recognize in 2021.

We have no deferred incremental costs incurred to obtain or fulfill our construction contracts or other service revenues, and 

had no significant credit loss expense on construction contracts receivable or unbilled construction revenue in 2020, 2019 and 
2018.

Earnings Per Share (“EPS”) and Earnings Per Unit (“EPU”)

COPT and Subsidiaries EPS

We present both basic and diluted EPS.  We compute basic EPS by dividing net income available to common shareholders 
allocable to unrestricted common shares under the two-class method by the weighted average number of unrestricted common 
shares outstanding during the period.  Our computation of diluted EPS is similar except that:

•

•

the denominator is increased to include: (1) the weighted average number of potential additional common shares that would 
have been outstanding if securities that are convertible into common shares were converted; and (2) the effect of dilutive 
potential common shares outstanding during the period attributable to COPT’s forward equity sale agreements, redeemable 
noncontrolling interests and our share-based compensation using the treasury stock or if-converted methods; and
the numerator is adjusted to add back any changes in income or loss that would result from the assumed conversion into 
common shares that we add to the denominator. 

Summaries of the numerator and denominator for purposes of basic and diluted EPS calculations are set forth below (in 

thousands, except per share data):

Commitments and Contingencies

Litigation and Claims

In the normal course of business, we are subject to legal actions and other claims.  We record losses for specific legal 
proceedings and claims when we determine that a loss is probable and the amount of loss can be reasonably estimated.  As of 
December 31, 2020, management believes that it is reasonably possible that we could recognize a loss of up to $3.1 million for 
certain municipal tax claims.  While we do not believe this loss would materially affect our financial position or liquidity, it 
could be material to our results of operations.  Management believes that it is also reasonably possible that we could incur 
losses pursuant to other such claims but do not believe such losses would materially affect our financial position, liquidity or 
results of operations.  Our assessment of the potential outcomes of these matters involves significant judgment and is subject to 
change based on future developments.

Environmental

We are subject to various Federal, state and local environmental regulations related to our property ownership and 
operation.  We have performed environmental assessments of our properties, the results of which have not revealed any 
environmental liability that we believe would have a materially adverse effect on our financial position, operations or liquidity. 

In connection with a lease and subsequent sale in 2008 and 2010 of three properties in Dayton, New Jersey, we agreed to 
provide certain environmental indemnifications limited to $19 million in the aggregate.  We have insurance coverage in place to 
mitigate much of any potential future losses that may result from these indemnification agreements. 

Tax Incremental Financing Obligation

Anne Arundel County, Maryland issued tax incremental financing bonds to third-party investors in order to finance public 

improvements needed in connection with our project known as the National Business Park.  These bonds had a remaining 
principal balance of approximately $33 million as of December 31, 2020.  The real estate taxes on increases in assessed values 
post-bond issuance of properties in development districts encompassing the National Business Park are transferred to a special 
fund pledged to the repayment of the bonds.  While we are obligated to fund, through a special tax, any future shortfalls 
between debt service of the bonds and real estate taxes available to repay the bonds, as of December 31, 2020, we do not expect 
any such future fundings will be required.

Effects of COVID-19

Since first being declared a pandemic by the World Health Organization in early March 2020, the coronavirus, or 
COVID-19, has spread worldwide.  In an effort to control its spread, governments and other authorities imposed restrictive 
measures affecting freedom of movement and business operations, such as shelter-in-place orders and business closures.  Strong 
restrictive measures were put into place in much of the United States beginning in March 2020, bringing many businesses to a 
halt while forcing others to change the way in which they conduct their operations, with much of the workforce working from 

F-60

 
 
 
 
 
 
Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

their homes to the extent they were able.  States and local governments began easing these measures to varying extents in late 
April 2020, with some lifting restrictive measures entirely, while others chose a more gradual, extended easing approach.  
While the easing of these measures enabled many businesses to gradually resume normal operations, most businesses continue 
to be hindered to varying extents by either measures still in effect, operational challenges resulting from social distancing 
requirements/expectations and/or a reluctance by much of the population to engage in certain activities while the pandemic is 
still active.  As of the date of this filing, COVID-19 spread continues world- and nation-wide, and is expected to continue until 
vaccinations have been administered to much of the population, which is not expected to occur in the United States until at least 
mid- to late 2021.  As a result, there continues to be significant uncertainty regarding the duration and extent of this pandemic.  
The outbreak significantly disrupted financial and economic markets worldwide, as well as in the United States at a national, 
regional and local level.  These conditions could continue or further deteriorate as businesses feel the prolonged effects of 
stalled or reduced operations and uncertainty regarding the pandemic continues.

COVID-19, and any similar pandemics should they occur, along with measures instituted to prevent spread, may adversely 

affect us in many ways, including, but not limited to:

•

•

•

•

•

•

disruption of our tenants’ operations, which could adversely affect their ability, or willingness, to sustain their businesses 
and/or fulfill their lease obligations;
our ability to maintain occupancy in our properties and obtain new leases for unoccupied and new development space at 
favorable terms or at all;
shortages in supply of products or services from our and our tenants’ vendors that are needed for us and our tenants to 
operate effectively, and which could lead to increased costs for such products and services;
access to debt and equity capital on attractive terms or at all.  Severe disruption and instability in the global financial 
markets or deteriorations in credit and financing conditions may affect our or our tenants’ ability to access capital necessary 
to fund operations, refinance debt or fund planned investments on a timely basis, and may adversely affect the valuation of 
financial assets and liabilities;
our and our tenants’ ability to continue or complete planned development, including the potential for delays in the supply 
of materials or labor necessary for development; and
an increase in the pace of businesses implementing remote work arrangements over the long-term, which would adversely 
effect demand for office space.

The extent of the effect on our operations, financial condition and cash flows will be dependent on future developments, 
including the duration of the pandemic and any future resurgence or variants thereof, the prevalence, strength and duration of 
restrictive measures and the resulting effects on our tenants, potential future tenants, the commercial real estate industry and the 
broader economy, all of which are uncertain and difficult to predict.
