Portions of the proxy statement of Corporate Office Properties Trust for its 20202023 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, 2019 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, 2019, COPT owned 98.7% 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:
consolidated financial statements;
the following notes to the consolidated financial statements:
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;
Note 18, Earnings per Share of COPT and subsidiaries and Earnings per Unit of COPLP and subsidiaries; and
Note 20, Quarterly Data of COPT and subsidiaries and COPLP and subsidiaries.
“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.

PART I
Item 1. Business

OUR COMPANY
General. Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company”, “we” or “us”) 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-likeurban submarkets in the Greater Washington, DC/Baltimore region with durable Class-A office fundamentals and characteristics (“Regional Office”). As of December 31, 2019,2022, our properties included the following:
170
194 properties totaling 19.223.0 million square feet comprised of 15.417.7 million square feet in 148166 office properties and 3.75.3 million square feet in 2228 single-tenant data center shell properties (“data center shells”).shells. We owned 1521 of these data center shells through unconsolidated real estate joint ventures;
a wholesale data center with a critical load of 19.25 megawatts;
14seven properties under development or redevelopment (ten(five office properties and fourtwo data center shells), including two partially-operational properties, that we estimate will total approximately 2.51.0 million square feet upon completion, including one partially-operational property;completion; and
approximately 900710 acres of land controlled for future development that we believe could be developed into approximately 11.39.5 million square feet and 43 acres of other land.

We conduct almost all of our operations and own almost all of our assets through our operating partnership, Corporate Office Properties, L.P. (“COPLP”) and subsidiaries (collectively, the “Operating Partnership”), of which COPT is the sole general partner. 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, 2019,2022, COPT owned 98.7%98.0% of the outstanding COPLP common units (“common units”); the remaining common units and all of the outstanding COPLPthere were no preferred units (“preferred units”) were owned by third parties.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. In the case of any series of preferred units held by COPT, there would be a series of preferred shares of beneficial interest (“preferred shares”) in COPT that is equivalent in number and carries substantially the same terms as such series of COPLP preferred units. 

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 Federalfederal 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.

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-basedknowledge- and technology-based activities (i.e., cyber security, research and development and other highly technicalhighly-technical defense and security areas) than to force structure (i.e., troops) and weapon system mass production. Our office and data center shell portfolio isproperties are significantly concentrated in Defense/IT Locations, which as of December 31, 20192022 accounted for 161186 of the portfolio’s 170our 194 properties, representing 87.9%89.7% of itsour annualized rental revenue, and we control developable land to accommodate future growth in this portfolio.these locations. 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 SecureSensitive Compartmented Information Facility (“SCIF”), critical power supply and operational redundancy. We believe that demand at these properties is driven by, and correlated with, national security spending, which we believe has made them less susceptible to the effects of conditions in the overall economy than typical office properties. These properties have also been less susceptible to remote work trends than typical office properties since the tenants often require their employees to work in the properties for security purposes.

In recent years,Our Defense/IT Locations include data center shells, have been a significant growth driver for our Defense/IT Locations. Data center shellswhich 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 2019, we placed into service 22 data center shells totaling 3.7 million square feet, and we had an additional four under development totaling 950,000 square feet as of December 31, 2019.  We enter into long-term leases for these properties prior to commencing development, with triple-net structures, rent escalators and multiple extension options and rent escalators to provide future growth.options. Additionally, our tenants’ significant funding of the costs to fully power and equip these properties significantlygreatly 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-basedknowledge- 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 such as Fort George G. Meade (which houses over 100 Department of Defense organizations and agencies, including onesthose 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 are primarilylocated in Northern Virginia, one of the largest data center markets in the Northern Virginia area, proximateworld due in large part to the MAE-East Corridor, which is a major Network Access Point inits central location along the United States for interconnecting traffic between Internet service providers;States’ eastern seaboard, robust fiber connectivity infrastructure and access to reliable and affordable utilities required to support operations;
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 uniquecomplex space and security-oriented requirements.needs.

Regional Office Strategy: While Defense/IT Locations are our primary focus, we also own a portfolio of office properties located in select urban/urban-likeurban 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 lifestyle-oriented locations with a robust high-end residential and retail base; (2) proximity to public transportation and major transportation routes; (3) an educated workforce; and (4) a diverse and growing employment base; and (5) constraints in supply of office space.base. As of December 31, 2019,2022, we owned sevensix Regional Office properties, representing 11.5%9.4% of our office and data center shell portfolio’s annualized rental revenue; theserevenue. These properties were comprised of: three high-rise Baltimore City properties proximate to the city’s waterfront; and fourtwo Northern Virginia properties proximate to existing or future Washington Metropolitan Area Metrorail stations and major interstates.interstates; and a property in Washington, D.C.’s central business district. We believe that demand for space in these properties is more correlated to changes in conditions in the overall economy than our Defense/IT Locations.

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,
6


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;program (targeting new office properties to meet LEED certification standards or, when not possible, striving to otherwise incorporate LEED criteria into property designs); (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”) prerequisitesguidelines for much of our portfolio, including guidelines pertainingcleaning, recycling, energy reduction and landscaping practices; (3) investing in building automation systems and high-efficiency heating and air conditioning equipment and implementing resource conservation practices to cleaningreduce energy consumption; (4) investing in water saving features; and recycling practices and energy reduction; and (4)(5) participating in the annual GRESB (or Global Real Estate Sustainability Benchmark)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 fiveeight years, representing the highest quadrant of achievement on the survey.

Property Development and Acquisition Strategy: We growexpand our operating portfolio primarily through property development opportunitiesdevelopments 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 in the faceirrespective of differing 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;activities and other capital needs;
raising equity through issuances of common shares and, to a lesser extent, issuances of common equity in COPLP and preferred equity;
recycling proceeds from sales of interests in properties, including through joint venture structures for certain investments, to fund property development and other investment activities and/or reduce overall debt;
paying dividends at a level that is at least sufficient for us to maintain our REIT status; and
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.

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; financially-supported learning programs; and employee recognition programs. We also grant common equity to all new full-time employees and provide our senior management team 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 contributions to 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.

Talent Development: We aim to attract, retain and develop our top talent throughout the employment cycle in order to enhance our talent pool. During 2022, our workforce size did not change significantly, with 64 new hires and 74 departures (an attrition rate of approximately 18.7%).

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 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 are good.to engage with
8


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.
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 that 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.affected.

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 andor ability to make expected distributions to our equityholders.shareholders. You should carefully consider each of these risks and uncertainties, andalong 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, 2019, which are2022 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 businessindustry, which in turn, could have an adverse effect onadversely affect our financial position, results of operations, cash flows andor 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 telecommutingremote work and flexible workplaces;work arrangements, open workspaces and coworking spaces;


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;
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 ourexisting or new 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 development costs for materials and labor;
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 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;
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;
9


adverse consequences resulting from climate-related risks; and
potential liability under environmental or other laws or regulations.

We
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, inflation or deflation, constrained credit and constrained credit.shortages of goods or services. Such conditions could potentially be triggered by geopolitical or other world events. 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 at all or leasing vacant space in existing properties or newly-developed properties. In addition, such conditions could disrupt the operations, or profitability, of our business or 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.

We may suffer adverse consequences as a result of our reliance on rental revenues for our income. We earn revenue from rentingleasing our properties. OurCertain of our operating costs do not necessarily fluctuate in relation to changes in our rental revenue. This means that certain of ourAs a result, 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, orincluding the USG and its contractors, including prolonged shutdowns of the government and actual, or potential, reductions in government spending targeting knowledge-based activities.contractors. As of December 31, 2019,2022, our 10 largest tenants accounted for 62.1%63.4% of our total annualized rental revenue, the fourthree largest of these tenants accounted for 50.6%48.9%, and the USG, our largest tenant, accounted for 34.6%35.5%. We calculate annualized rental revenue by multiplying by 12 the sum of monthly contractual base rents (ignoring free rent then in effect and rent associated with tenant funded landlord assets) and estimated monthly expense reimbursements under active leases in our portfolio as of December 31, 2019;2022; with regard to properties owned through unconsolidated real estate joint ventures, we include the portion of annualized rental revenue allocable to our ownership interest.interests. 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 four 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.

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 in recent years 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.

As of December 31, 2019, 87.9%2022, 89.7% 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 offrom properties in these locations. A reduction in government spending targeting the activities of the government and its contractors (such as knowledge-basedknowledge- 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 existing or new tenants engaged in these activities.

Our future ability to fuel growth 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 growth driver for our Defense/IT Locations strategy. Since 2013, we have placed into service 28 data center shells totaling 5.3 million
10


square feet, and we had an additional two under development totaling 420,000 square feet as of December 31, 2022. 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 develop data center shells to fuel growth and use as a possible source of 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. OurMany of 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. SomeCertain businesses increasingly permit employee telecommuting,have implemented remote work and flexible work schedules,arrangements and/or utilized open workplacesworkspaces and teleconferencing. There is also an increasing trend of businesses utilizing shared office and co-workingcoworking spaces. These practices could enable businesses to reduce their office space requirements. TheseA continuation or acceleration of these trends could over time erode the overall demand for commercial 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 or property type, 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 for space 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.our ability, or willingness, to execute plans to sell properties.



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;publicly-traded REITs and large private equity backed entities and funds; 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 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 may be 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 be unable to successfully 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 andor redevelop properties, we assume a number of risks, including, but not limited to, the risk ofof: actual costs exceeding our budgets,budgets; conditions or events occurring that delay or preclude our ability to complete the project completion andas originally planned or at all; projected leasing not occurring. In addition, we may find that we are unable to successfully execute plansoccurring as expected or at all, or occurring at lower than expected rental rates; and not being able 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.

11


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 other acquisitions where we aremore familiar with the regions, such as the risk that we doour not sufficiently anticipateanticipating conditions or trends in a new marketsuch regions and therefore are not being able to operate the acquired propertyproperties profitably.

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 properties may be difficult to reposition for alternative uses. Certain of our 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 data center 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.

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 may be required to terminate the lease or other agreement. 

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 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 refinance 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, which could result in reduced distributions to our equityholders or the need for us to incur additional debt to fund these 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.

Some 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, 2019, we had $1.8 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”). The Chief Executive of the United Kingdom's Financial Conduct Authority (“FCA”), which regulates LIBOR, announced the FCA’s intention to cease sustaining LIBOR after 2021. He has also indicated that market participants should expect LIBOR to be subsequently discontinued and should proceed with preparations for transitioning to an alternative reference rate. The Federal Reserve Board convened the Alternative Reference Rates Committee (“ARRC”) to identify a set of alternative reference rates for possible use as market benchmarks. Based on the ARRC’s recommendation, the Federal Reserve Bank of New York began publishing the Secured Overnight Financing Rate (“SOFR”) and two other alternative rates beginning in April 2018. Since then, certain derivative products and debt securities tied to SOFR have been introduced, and various industry groups are developing plans to transition to SOFR as the new market benchmark. 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 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 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.

Our ability to pay distributions is further limited by the requirements of Maryland law. As a Maryland REIT, COPT may not under applicable Maryland law make a distribution if either of the following conditions exists after giving effect to the distribution: (1) the REIT would not be able to pay its debts as the debts become due in the usual course of business; or (2) the REIT’s total assets would be less than the sum of its total liabilities plus the amount that would be needed, if the REIT were


dissolved at the time of the distribution, to satisfy upon dissolution the rights of equityholders whose preferential rights are superior to those receiving the distribution. Therefore, we may not be able to make expected distributions to our equityholders if either of the above described conditions exists for COPT after giving effect to the distribution.

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 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.

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 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 our government.  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 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.

We may be subject to possible environmental liabilities. We are subject to various Federal,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. Anyonefacility; 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 would incur losses if third parties to whom we make loans fail to service or repay such loans. We enter into loan arrangements with tenants of our properties and other third parties. We would incur losses if these parties failed to fulfill their obligations to service and repay such loans.

We may be adversely affected by natural disastersthe impact of climate-related risks. We may be adversely affected by extreme weather events, such as hurricanes, floods and tornadoes, which could result in significant property damage and make it more difficult for us to obtain affordable insurance coverage in the effects of climate change. Natural disasters, including earthquakes and severe storms could adversely impact our properties. The potential consequences of climate changefuture. Longer term, we could also adversely impact our properties, particularly our ones locatedface the potential for more frequent or destructive severe weather events and shifts in Baltimore City near the waterfront,temperature and over time,precipitation amounts. Such events could adversely affect our properties in a number of ways, including, but not limited to: declining demand for spacespace; our ability to operate them effectively and profitably; their valuations; and our ability to operatesell them or use them as collateral for future debt. In addition to the properties effectively andpotential for climate-related physical risks, we expect that we could be adversely affected by regulatory changes made in response to climate change. For example, the Climate Solutions Now Act of 2022, which was passed by the State of Maryland with the goal of achieving targeted reductions in greenhouse gas emissions, is expected to result in building code changes and new energy performance standards in the State that may require us to make additional operating costs.investments in building systems for new and existing properties in order to comply, and may also subject us to additional fees. While the details of implementing this law are still being finalized by the State, the additional costs that may result from this law and any other similar federal, state or local laws or regulations in the future could be substantial.

Terrorist attacksAttacks by terrorists or foreign nations 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


Attacks by terrorists or foreign nations, 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,attacks 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 whichthat could increase vacancies in our properties and force us to lease space on less favorable terms.adversely affect property rental rates and valuations.

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.
12



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. Moreover, there are some loss events for which we cannot obtain insurance at reasonable costs, or at all, such as acts of war. With respect to such losses and losses from acts of terrorism, earthquakes, fires, pandemics or other catastrophic events, if we experience a loss that is uninsured or that exceeds policy limits, we could lose the capital invested in the damaged properties, as well as the anticipated future revenue from those properties. Depending on the specific circumstances of each affected property, it is also possible that we could be liable for mortgage indebtedness or other obligations related to the property.

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. These 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; such a dispute could also result in a sale of either our ownership interest in a joint venture or the joint venture’s underlying properties at a suboptimal price or time. 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.parties that provide goods and services to the USG. These agencies review a contractor’ssuch parties’ performance under its contracts, cost structure, internal controls systems and policies 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 uncoversof us were to uncover improper or illegal activities associated with our activities for the USG, 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. This requirement limits the extent to which we are able to fund our investment activities using retained cash flow from operations. Therefore, our ability to fund much of these activities is dependent on our ability to externally generate capital through issuances of new debt, common shares, preferred shares, common or preferred units in COPLP 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. As of December 31, 2022, we had $2.3 billion in debt, the future maturities of which are set forth in Note 10 to our consolidated financial statements. Payments of principal and interest on our debt may leave us with insufficient cash to operate our properties or pay distributions to COPT’s ownershipshareholders 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
13


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.

Virtually all 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.

Our operations likely will not generate enough cash flow to repay all of our debt without additional borrowings, equity issuances and/or sales of interests in properties. If we cannot refinance, extend the repayment date of, or otherwise raise funds required to repay, 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.

A downgrade in our credit ratings would materially adversely affect our business and financial condition. Our 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 our 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 to its shareholders 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 and 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 equity that dilutes our shareholders’ interests. We may issue additional common shares or new issuances of preferred shares without shareholder approval. Similarly, we may issue additional common or preferred units in COPLP for contributions of cash or property without approval by our shareholders. Our existing shareholders’ 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 important factors.not limited to:

market perception of REITs in general and office REITs in particular;
market perception regarding our major tenants and property concentrations;
the level of institutional investor interest in us;
general economic and business conditions;
prevailing interest rates;
our financial performance;
our underlying asset value;
our actual, or market perception of our, financial condition, performance, dividends and growth potential; and
adverse changes in tax laws.

We may be unable to continue to make distributions to our shareholders at expected levels. We expect to make regular quarterly cash distributions to our shareholders. 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 for 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;
14


our corporate overhead levels;
our amount of uninsured losses; and
our decision to reinvest available cash into operations rather than distribute it.

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

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 our debt may limit our ability to make some types of payments and distributions in the event of certain default situations. This may limit our ability to make some types of payments, including payment of distributions on common or preferred shares, 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 equity that we may issue 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. 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.

Other Risks

We may suffer adverse effects from the COVID-19 pandemic and similar pandemics. COVID-19 and its variants, 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 affect 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 and extent 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. 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 its variants, and any similar pandemics should they occur, and the responses to curb 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.

Our business could be adversely affected by security breaches through cyber attacks, cyber intrusions or other factors, and other significant disruptions of our IT networks and related systems. We face risks associated with security breaches and other significant disruptions of our IT networks and related systems, which are essential to our business operations. Such breaches and disruptions may occur through cyber-attacks or -intrusions over the Internet, malware, computer viruses, attachments to e-mails or by actions of persons inside our organization, including those with access to our systems. 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 or -intrusions, 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 avoid breaches and disruptions that were individually, or in the aggregate,
15


material. The Audit Committee of our Board of Trustees oversees our risk management processes related to cybersecurity and meets with management to discuss recent trends and our strategy to defend our infrastructure against cyber-attacks and intrusions on a quarterly basis. 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. We also have insurance coverage in place in the event of significant future losses from breaches and disruptions; however, continuing changes in the insurance industry’s risk assessment approach and pricing structure could in the future increase the cost for us to obtain insurance coverage or decrease the scope of such coverage available to us.

Like other businesses, we have been, and expect to continue to be, subject to cyber-attacks or -intrusions, computer viruses or malware, attempts at unauthorized access and other events of varying degrees. A security breach or other significant disruption involving our IT networks and related systems could:

disrupt the proper functioning of our networks and systems and therefore our operations and/or those of certain of our tenants;
increase the likelihood of missed reporting or permitting deadlines;
affect our ability to properly monitor our compliance with rules and regulations regarding our qualification as a REIT;
result in unauthorized access to, and/or destruction, loss, theft, misappropriation or release of, proprietary, confidential, sensitive or otherwise valuable information of ours or others, which others could use to compete against us or which could expose us to damage claims by third-parties;
disrupt or disable the building systems relied upon by us and our tenants for the effective and efficient use of our properties;
require significant management attention and resources to remedy any resulting damages;
subject us to termination of leases or other agreements or claims for breach of contract, damages or other penalties; and
damage our reputation among our tenants and investors generally.

Additionally, a successful attack on our vendors or service providers could result in a compromise of our own network or a disruption in our supply chain or services upon which we rely.

Our business could be adversely impacted if we are unable to attract and retain highly-qualified personnel. Our ability to operate effectively and succeed in the future is dependent in large part on our employees. Our Defense/IT Locations strategy in particular relies on the knowledge, specialized skills and credentialed personnel on our teams that serve those properties’ unique needs. We face very intense competition for highly-qualified personnel in the labor market. We also occasionally face even greater competition for personnel with certain skill sets or qualifications. As a result, we may not be successful in retaining our existing talent or attracting, training and retaining new personnel with the requisite skills. We may also find that we need to further increase compensation costs in response to this competition. Our business could be harmed by the loss of key employees, a significant number of employees or a significant number of employees in a specialized area of the Company.

We have certain provisions or statutes that may serve to delay or prevent a transaction or a change in control that would be advantageous to our shareholders from occurring. 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 theour 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/unitsshares or otherwise be in the best interest of our equityholders.shareholders.

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. VariousIn addition, various Maryland laws may have the effect of discouraging offers to acquire us, even if the acquisition would be advantageous to equityholders.shareholders. 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 provisionslaws 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.shareholders. We believe that COPT has qualified for taxation as a REIT for Federalfederal 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 areCOPT is 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
16


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 Federalfederal income tax at regular corporate rates. Also, unless the Internal Revenue Service granted us relief under certain statutory provisions, COPT would remain disqualified asfrom being 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.shareholders. In addition, if COPT fails to qualify as a REIT, it willwould 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.shares.

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 becomebecoming 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.shareholders.

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.

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 majorOur tenants and sector concentrations;
contractual counterparties could be designated “Prohibited Persons” by the levelOffice of institutional investor interestForeign 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 COPT;
general economic andtransactions with Prohibited Persons. If a tenant or other party with whom we conduct business conditions;
prevailing interest rates;
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 our financial performance;

market perception of our financial condition, performance, dividends and growth potential; and

lease or other agreement with them. 
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.

(1)This percentage is based upon all rentable square feet or megawatts under lease terms that were in effect as of December 31, 2019.
(2)Annualized rental revenue is the monthly contractual base rent as of December 31, 2019 (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, 2019. 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 $30.95 for our total office and data center shell portfolio, $33.30 for the Fort Meade/BW Corridor (our largest Defense/IT Location sub-segment) and $32.50 for our Regional Office portfolio.

Item 6. Selected Financial Data[Reserved]

The following tables set forth summary historical consolidated financial and operating data for COPT and COPLP and their respective subsidiaries as of and for each of the years ended December 31, 2015 through 2019. Our revenues relating to real estate operations are derived from revenue earned from tenant leases on our properties. Most of our expenses relating to our real estate operations take the form of property operating costs (such as real estate taxes, utilities and repairs and maintenance) and depreciation and amortization associated with our operating properties. Our profitability from real estate operations is highly dependent on our occupancy and rental rates, both of which are affected by a number of factors. You should read the following summary historical financial data in conjunction with the consolidated financial statements and notes thereto of COPT and its subsidiaries and COPLP and its subsidiaries and the section of this report entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for additional information.

Overview

Our 2019 was highlighted by:In 2022, we:

record-breakingachieved strong tenant retention and vacant space leasing volume,driven by high leasing demand for space in our large concentration of Defense/IT Locations, which helped fuel;more than offset the effect of lagging demand in our Regional Office properties;
acceleratedplaced into service our second highest annual total of newly developed square feet on record, all in our Defense/IT Locations;
ended the year with additional new Defense/IT Locations under development volume that we funded in large part using; andwere substantially pre-leased;
raised capital raised by selling interests infrom property dispositions, including from our wholesale data center, shells through a newly-formed joint venture.to create borrowing capacity available to fund development of new Defense/IT Locations; and
refinanced our Revolving Credit Facility and an unsecured term loan, after which we had no significant remaining debt maturing until 2026.

We leased 4.93.0 million square feet in 2019, exceeding2022 in our previous all-time high set in 2010 by 14%.portfolio, which ended the year 92.7% occupied and 95.2% leased. This leasing volume was highlighted by:by a strong portfolio-wide retention rate of 72.1% and our highest annual vacancy leasing volume in 12 years.

record-breaking development

Our leasing performance in 2022 was driven by the strength of our Defense/IT Locations, which represented 89.7% of our annualized rental revenues and 90.7% of our square feet as of December 31, 2022. This segment ended the year 94.1% occupied and 96.7% leased, representative of high utilization rates and slightly increased relative to year end 2021, due in large part to:

vacant space leasing of 2.2 million719,000 square feet, which exceeded our previous record set in 2012 by 81%, and came on the heels of last year’s near-record volume. This year’s development leasing volume was highlighted by:feet;
1.2placing into service 1.3 million square feet in our data center shell sub-segment;nine newly developed properties that were 99% leased; and
548,000renewing 78.8% of the square feet in our Redstone Arsenal sub-segment in Huntsville, Alabama, which exceededscheduled to expire during the combined total square footage previously placed in service by us in that sub-segment since our entry nearly 10 years ago; andyear.
348,000 square feet in a property to be occupied by the USG in our Northern Virginia Defense/IT sub-segment.
vacant space leasing totaling 784,000 square feet, representing our highest annual volume since 2010, mostAs of which was in the Fort Meade/BW Corridor and Northern Virginia Defense/IT sub-segments and Regional Office segment; and


a portfolio-wide tenant retention rate of 76.7% (or 79.1% for our Defense/IT Locations) achieved by renewing leases on 1.9December 31, 2022, this segment had an additional 1.0 million square feet (defined belowunder development that were 85% leased, which included 476,000 in the section entitled “Occupancy and Leasing”). Strong tenant retention is key to our asset management strategydevelopment leasing completed in order to maximize revenue (by avoiding downtime) and minimize leasing capital.

2022. We believe that these leasing results were attributable in large part to:this segment has strongly benefited from continued:

a healthy defense spending environment and continued bipartisan support towardsfor increased funding of our national defense. SuccessiveWe believe that successive increases in defense spending since 2016, including, a two-year budget deal signed into lawmost recently, in August 2019 that removed the possibilityFiscal 2023 National Defense Authorization Act, coupled with the absence of sequestration cuts by raising spending caps previously set forth underextended delays in defense appropriations legislation in recent years, have enhanced the Budget Control Act of 2011, increased USG and defense contractor tenants’ ability to invest in facility planning. This benefitedenvironment has helped fuel leasing demand, as has continued prioritization of spending allocations towards technology and innovation programs benefiting our 2019 leasing results, as demand forDefense/IT Locations, including cyber, space, worked its way through the Government’s appropriations process, fueling USGunmanned systems and defense contractor demand for new spaceartificial intelligence; and expansion into previously vacant space; and
continued demand for data center shells. Our leasing included fivetwo new data center shells for an existing customer in Northern Virginia, the largest data center market in the world, and represented further expansion of our relationship with an existing defense contractor customer.world. As of year end, we held land that we believe would accommodate andevelopment of three additional 934,000data center shells totaling 647,000 square feet.

Since demand for this segment is driven by, and correlated with, national security spending, we believe it has been less susceptible to the effects of conditions in the overall economy in recent years than typical office properties, and we fully expect that strong demand will continue to benefit this segment well into 2024.

The strong leasing performance in our Defense/IT Locations in 2022 more than offset the effect of lagging demand in our Regional Office segment, which has experienced a challenging leasing environment since 2020 that has not improved. Our Regional Office segment ended the year 79.0% occupied and 80.8% leased, both decreases of approximately 10% relative to year end 2021. These decreases are attributable to a 23.8% renewal rate and minimal vacancy leasing in 2022. We believe that demand for space in Regional Office Properties is more correlated to changes in conditions in the overall economy than our Defense/IT Locations.

As of December 31, 2022, we had scheduled lease expirations for 1.7 million square feet in future data center shell development.2023, representing 8.0% of our total occupied square feet and 9.8% of our total annualized rental revenue, including:

These leasing results contributed1.5 million square feet in our Defense/IT Locations segment, a high proportion of which we expect to renew; and
170,000 square feet in our ending the year with our office and data center shell portfolio 94.4% leased (comparedRegional Office segment, most of which we do not expect to 93.9% as of December 31, 2018) while our Same Properties were 93.7% leased (compared to 93.5% as of December 31, 2018). Our year-end portfolio-wide office and data center shell occupancy was 92.9% (compared to 93.0% as of December 31, 2018) and Same Property occupancy was 91.9% (compared to 92.6% as of December 31, 2018). Our wholesale data center was 76.9% leased at year end (compared to 87.6% as of December 31, 2018). renew.

Please refer to the section below entitled “Occupancy and Leasing” for additional related disclosure.

Our record development leasing fueled an expansion of our overall development activity. We ended the year with 2.3 million square feet in properties under development, an increase of 114% from the end of last year. While our activity included 950,000 square feet in data center shells under development at year end (a 30.0% increase since the end of last year), most of the increased activity was attributable to our Redstone Arsenal sub-segment, where we had six properties totaling 756,000 square feet under development. Our year-end development at Redstone Arsenal included two properties being built on a speculative basis in order to keep pace with what we believe to be very strong demand, illustrated by that sub-segment’s 99.3% year-end occupancy rate and its absorption of 100% of the space in two properties on which we commenced development on a speculative basis last year. For further disclosure regarding our development underway as of year end, please refer to Item 2 of this Annual Report on Form 10-K. In 2019, we placed into service 1.2 million square feet that were 100% leased in nine newly-developed and one redeveloped Defense/IT Locations, comprised primarily of 946,000 square feet in data center shell space.

We funded muchraised $282.8 million in capital from sales of this development activity by selling, throughproperty interests, including:

$222.5 million from our sale of 9651 Hornbaker Road in Manassas, Virginia, our largest real estate investment (in terms of book value) and only property in our Wholesale Data Center reportable segment, on January 25, 2022, resulting in a seriesgain on sale of transactions,$28.6 million; and
$60.3 million from our sale of a 90% interest in ninetwo data center shells basedin Northern Virginia on an aggregate property valueDecember 14, 2022, resulting in a gain on sale of $345.1 million, retaining$19.2 million. We retained a 10% interest in the properties through BREIT COPT DC JV LLC (“BREIT-COPT”), a newly-formed joint venture. The transactions

We used substantially all of the proceeds from these sales to pay down debt, including our Revolving Credit Facility and an unsecured term loan, in order to free up borrowing capacity available to fund development activities.

We refinanced our only significant 2022 and 2023 debt maturities on October 26, 2022, when we entered into a credit agreement with a group of lenders that provided for sevenan aggregate of these properties were completed on June 20, 2019$725.0 million of available borrowings, including:

an unsecured revolving credit facility with a lender commitment of $600.0 million that replaced our existing Revolving Credit Facility; and for
a $125.0 million unsecured term loan, the proceeds of which we used to pay off the remaining two properties on December 5, 2019. Our partner in$100.0 million outstanding under an existing unsecured term loan and pay down a portion of our Revolving Credit Facility.

Due to the joint venture acquired the 90% interest from us for $310.6 million, resulting incollective effect of our recognition of a $105.2 million gain on sale, and we received an additional $20.12022 activity, we:

funded $283 million in net proceeds associated withdevelopment costs; and
ended the joint venture’s entry into non-recourse mortgage loans on the properties. This transaction enabled us to monetize the value that we created through our development of these properties and then reinvest towards funding our development activity for 2019 and much of 2020.year with:

While we used borrowings$389.0 million in borrowing capacity available under our Revolving Credit Facility to initially fund mostinvesting activities;
slightly less debt in total and as a percentage of total assets relative to year end 2021; and
no significant debt balloon payments due until 2026.

On January 10, 2023, we raised an additional $190.2 million from our development costs, we were able to more than repay those borrowings using:

sale of a 90% interest in three data center shells in Northern Virginia, resulting in a gain on sale of approximately $49 million. We retained a 10% interest in the $330.7 million in netproperties through a newly-formed joint venture. We used virtually all of the proceeds from the BREIT-COPT transactions discussed above; and
$46.5 million in net proceeds from COPT’s issuance of 1.6 million common shares under forward equitythis sale agreements originated in 2017 that COPT contributed into COPLP in exchange for an equal number of units in COPLP.

As a result, we were able to fund $394.4 million in development costs in 2019 while ending the year with a lower ratio of debt to total assets and morefree up additional borrowing capacity available under our Revolving Credit Facility than whento fund future development.

In 2022 and through the date of this filing, the United States economy experienced inflationary conditions, increased interest rates, higher volatility in the debt and equity capital markets, certain supply-chain related shortages and declines in gross domestic product in the first two quarters. For us:

the above economic conditions have not significantly affected our ability to achieve expected leasing in our Defense/IT Locations, while our Regional Office properties continue to experience a challenging leasing environment that has not improved;
inflationary conditions have contributed to increased costs for certain property operating expenses and building equipment and materials, which affects our development of new properties and improvements for existing properties, although long-term contracts previously in place for much of our property operating costs have buffered our exposure to these increases to a certain extent. In addition, for:
property operating expenses, most of our leases obligate tenants to pay either their full share of a building’s operating expenses or their share to the extent such expenses exceed amounts established in their leases. These lease arrangements reduce our exposure to increases in property operating expenses;
new property development and tenant improvements associated with new leasing in our Defense/IT Locations, increased costs have not significantly affected our ability to achieve targeted yields on new development and new leasing of existing properties due to continued strong demand for space, which has generally enabled us to increase rents to maintain such yields. However, continued cost increases could adversely affect our ability to continue to achieve targeted yields on future new property development and future new leasing of existing properties to the extent increases in market rental rates do not keep pace, which could also reduce our willingness to commence development of new properties; and
other capital improvements, the increasing cost environment could increasingly affect our willingness, or timeline, for completing such improvements;
increased interest rates have not yet significantly affected our borrowing costs due in large part to debt refinancings that we begancompleted in 2020 and 2021. Our debt is predominantly fixed rate and in the year, leaving us with $632.0form of long-term unsecured notes. In addition, for variable rate loans, we have used interest rate swaps to hedge the effect of interest rate increases on variable rate debt, including swaps for a $200.0 million notional amount that: fixed the one-month LIBOR interest rate in capacity as2022 at 1.9% through December 1, 2022; and, effective February 1, 2023, fixed the one-month SOFR interest rate at 3.7% for a three-year term;
we have observed constraints in the availability of December 31, 2019.unsecured bank debt. However, we were able to complete the credit agreement on October 26, 2022 that provided for the new Revolving Credit Facility and unsecured term loan, and now have no significant debt maturing until 2026; and

supply-chain related shortages have not had a significant effect on our ability to execute our operating and development activities.
Net
We believe that the effect of increased interest rates and capital market volatility on potential buyers could adversely affect our ability to execute plans to sell interests in properties.

For our 2022 results of operations:

diluted earnings per share increased 125.0% and net income in 2019 was $121.4increased $97.2 million, higher than in 2018or 119.2%, relative to 2021 due primarily to lower debt extinguishment losses that were offset in part by lower gains from sales of properties;
diluted funds from operations per share adjusted for comparability increased 3.1% and the gain on salenumerator for that we recognized from the BREIT-COPT transactions. Mostmeasure increased $8.6 million, or 3.3%, relative to 2021, much of the remaining increase in net incomewhich was attributable to a $14.0 million increase in lower interest expense;
net operating income (“NOI”) from real estate operations, our segment performance measure, discussed further below, whichincreased $1.4 million, or 0.4%, relative to 2021. This change was comprised primarily of the following:


included: a $13.5$20.8 million increase from newly developed properties newly placed intoin service; offset in part by
a $7.6$14.3 million increasedecrease from sales of interests in properties (most notably, our wholesale data center sold in January 2022) and;
24



a $5.3 million decrease from our Same Properties; and a net decrease of $6.4 million from dispositions (dueProperties attributable primarily to decreased occupancy in our decrease in ownership of the properties included in the BREIT-COPT transactions discussed above). The increase in same property NOI was attributable to increased rental revenue for our Defense/IT Locations due in large part to leasing of previously vacant space. Regional Office segment.

Additional disclosure comparing our 20192022 and 20182021 results of operations is provided below.

We discuss significant factors contributing to changes in our net income between 20192022 and 20182021 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 and obtain cash for short and long-term capital needs; and
our commitmentsmaterial cash requirements for known contractual and contingencies.other obligations.

We refer to the measuremeasures “annualized rental revenue” and “tenant retention rate” 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)effect and rent associated with tenant funded landlord assets). Our computation of annualized rental revenue excludes the effect of lease incentives, although the effect of this exclusion is not material.incentives. 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 and segment analysis. Tenant retention rate is a measure we use that represents the percentage of square feet renewed in a period relative to the total square feet scheduled to expire in that period; we include the effect of early renewals in this measure.

We also refer to the measures “cash rents”, “straight-line rents”, and industry analysis.“committed costs” in the “Occupancy and Leasing” section of the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of this Annual Report on Form 10-K. Cash rents include monthly contractual base rent (ignoring rent abatements and rent associated with tenant funded landlord assets) multiplied by 12, plus estimated annualized expense reimbursements (as of lease commencement for new or renewed leases or as of lease expiration for expiring leases). Straight-line rents includes annual minimum rents, net of abatements and lease incentives and excluding rent associated with tenant funded landlord assets, on a straight-line basis over the term of the lease, and estimated annual expense reimbursements (as of lease commencement for new or renewed leases or as of lease expiration for expiring leases). We believe that cash rents and straight-line rents are useful measures for evaluating the rental rates of our leasing activity, including changes in such rates relative to rates that may have been previously in place, with cash rents serving as a measure to evaluate rents at the time rent payments commence, and straight-line rents serving as a measure to evaluate rents over lease terms. Committed costs includes tenant improvement allowances (excluding tenant funded landlord assets), leasing commissions and estimated turn key costs and excludes lease incentives; we believe this is a useful measure for evaluating our costs associated with obtaining new leases.

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 andor assumptions that (1) require our most difficult, subjective or complex judgments in accounting for uncertain matters or matters that are susceptible to changeinvolve a significant level of estimation uncertainty and (2) materially affecthave had or are reasonably likely to have a material impact on our reported operating performancefinancial condition or financial condition.results of operations. 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.

Assessment of Lease Term as Lessor

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 (with defined rent escalations upon renewal), 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 operating leases, net of rent abatements, on a straight-line basis over the term of each lease. TheWe estimate a tenant’s lease term of a lease includes the noncancellable periods ofat the lease along with periods covered by: (1) a tenant option to extendcommencement date and do not subsequently reassess such term unless the lease if the tenant is reasonably certain to exercise that option; (2)modified. When estimating a tenant option to terminate thetenant’s 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,term, 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 forto the tenant based on any existing contract, asset, entity or market-based factors inassociated with 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 lesseetenant vacating or discontinuing use of the leased property. For most of our leases with the USG, we have determined, based on the factors above,our estimates of lease term conclude 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 inAs a result, our recognition of minimum rents on these leases includes the effect of annual rent escalations over our estimate of the lease term assessments(including on one-year renewal options) and our depreciation and amortization of costs incurred on these leases is recognized over the lease term. An over-estimate of the term of these leases by us 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. We had no significant USG leases with lease terms determined to have been over-estimated during the reporting periods included herein.

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 recoveryrecoverability 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 for a property, 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 In our accounting for impairment of long-lived assets, we estimate property fair values are estimated based on contract prices, indicative bids, discounted cash flow analyses or comparable sales analyses. EstimatedWe estimate cash flows used in ourperforming impairment analyses are based on our plans for the property and our views of market and economic conditions. TheOur 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 theOur determination of appropriate capitalization or discount raterates for use in estimating property fair values 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.

AssetSince 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,sell, decisions by us 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. TheOur 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

MostHistorically, future market rental and occupancy rates have tended to be the most variable assumption in our impairment analyses of properties to be held and used; while changes in these assumptions can significantly affect our leases involve some formestimates of improvementsproperty undiscounted future cash flows in our recoverability analyses, such changes historically have not usually resulted in impairment losses since the resulting recoverability analyses still have tended to leased space. When we are required to provide improvements underexceed 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 costcarrying value of the improvements and recognize depreciation expense associated withproperty asset groups. Historically, our recognition of impairment losses has most often occurred due to changes in our estimates of future cash flows resulting from a change in our plans for a property, such improvements 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 fundeda decision by us asto sell or shorten our expected holding period for a lease incentive assetproperty or to not develop a property. Changes in the estimated future cash flows due to changes in our plans for a property or significant changes in our views regarding property market and amortize it as a reductioneconomic conditions and/or our ability to obtain development rights could result in recognition 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.impairment losses that could be substantial.


26


In determining whether improvements constitute landlord or tenant assets, we consider numerous factors that may require subjective or complex judgments, including: whether the improvements are unique to the tenant or reusable by other tenants; whether the tenant is permitted to alter or remove the improvements without our consent or without compensating us for any lost fair value; whether the ownership of the improvements remains with us or remains with the tenant at the end of the lease term; and whether the economic substance of the lease terms is properly reflected.

Northern Virginia Defense/IT: Occupancy decreased due primarily to two large tenant vacancies during2023, we believe that the year. As of December 31, 2019, eight of the 13 properties in this sub-segment had combined occupancy of 98.0%, while the other five properties had combined occupancy of 55.3%, and we had scheduled lease expirations in the sub-segment in 2020 for 121,000 square feet, or 7% of itsweighted average annualized rental revenue per occupied square feet. This sub-segment was 87.7% leased as of year end (inclusive of 106,000 square feet underfoot for such leases yet to commence);
Regional Office: Includes properties in Baltimore City and two sub-markets in Northern Virginia. While total occupancy in this segment decreased only slightly from year end 2018 to 2019, occupancy decreases in our Baltimore City properties (which were 89.4% occupied as of December 31, 2019)2022, on average, approximated estimated current market rents for the related space, with specific results varying by market.

Overview

In 2022, we:

achieved strong tenant retention and vacant space leasing driven by high leasing demand for space in our large concentration of Defense/IT Locations, which more than offset the effect of occupancy increaseslagging demand in our Regional Office properties;
placed into service our second highest annual total of newly developed square feet on record, all in our Defense/IT Locations;
ended the Northern Virginia properties (whichyear with additional new Defense/IT Locations under development that were 85.0%substantially pre-leased;
raised capital from property dispositions, including from our wholesale data center, to create borrowing capacity available to fund development of new Defense/IT Locations; and
refinanced our Revolving Credit Facility and an unsecured term loan, after which we had no significant remaining debt maturing until 2026.

We leased 3.0 million square feet in 2022 in our portfolio, which ended the year 92.7% occupied and 95.2% leased. This leasing was highlighted by a strong portfolio-wide retention rate of 72.1% and our highest annual vacancy leasing volume in 12 years.

22



Our leasing performance in 2022 was driven by the strength of our Defense/IT Locations, which represented 89.7% of our annualized rental revenues and 90.7% of our square feet as of December 31, 2019). 2022. This segment ended the year 94.1% occupied and 96.7% leased, representative of high utilization rates and slightly increased relative to year end 2021, due in large part to:

vacant space leasing of 719,000 square feet;
placing into service 1.3 million square feet in nine newly developed properties that were 99% leased; and
renewing 78.8% of the square feet scheduled to expire during the year.

As of December 31, 2019,2022, this segment had an additional 1.0 million square feet under development that were 85% leased, which included 476,000 in development leasing completed in 2022. We believe that this segment has strongly benefited from continued:

bipartisan support for increased funding of our national defense. We believe that successive increases in defense spending since 2016, including, most recently, in the Fiscal 2023 National Defense Authorization Act, coupled with the absence of extended delays in defense appropriations legislation in recent years, 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 for an existing customer in Northern Virginia, the largest data center market in the world. As of year end, we held land that we believe would accommodate development of three additional data center shells totaling 647,000 square feet.

Since demand for this segment is driven by, and correlated with, national security spending, we believe it has been less susceptible to the effects of conditions in the overall economy in recent years than typical office properties, and we fully expect that strong demand will continue to benefit this segment well into 2024.

The strong leasing performance in our Defense/IT Locations in 2022 more than offset the effect of lagging demand in our Regional Office segment, which has experienced a challenging leasing environment since 2020 that has not improved. Our Regional Office segment ended the year 79.0% occupied and 80.8% leased, both decreases of approximately 10% relative to year end 2021. These decreases are attributable to a 23.8% renewal rate and minimal vacancy leasing in 2022. We believe that demand for space in Regional Office Properties is more correlated to changes in conditions in the overall economy than our Defense/IT Locations.

As of December 31, 2022, we had scheduled lease expirations in 2020 for 77,000 square feet, or 4% of this segment’s occupied square feet; and
Other: As of December 31, 2019, our Other segment included two properties totaling 157,0001.7 million square feet in Aberdeen, Maryland.2023, representing 8.0% of our total occupied square feet and 9.8% of our total annualized rental revenue, including:

In 2019, we leased 4.91.5 million square feet including 2.2 millionin our Defense/IT Locations segment, a high proportion of which we expect to renew; and
170,000 square feet in our Regional Office segment, most of which we do not expect to renew.

Please refer to the section below entitled “Occupancy and Leasing” for additional related disclosure.

We raised $282.8 million in capital from sales of property interests, including:

$222.5 million from our sale of 9651 Hornbaker Road in Manassas, Virginia, our largest real estate investment (in terms of book value) and only property in our Wholesale Data Center reportable segment, on January 25, 2022, resulting in a gain on sale of $28.6 million; and
$60.3 million from our sale of a 90% interest in two data center shells in Northern Virginia on December 14, 2022, resulting in a gain on sale of $19.2 million. We retained a 10% interest in the properties through a newly-formed joint venture.

We used substantially all of the proceeds from these sales to pay down debt, including our Revolving Credit Facility and an unsecured term loan, in order to free up borrowing capacity available to fund development activities.

We refinanced our only significant 2022 and 2023 debt maturities on October 26, 2022, when we entered into a credit agreement with a group of lenders that provided for an aggregate of $725.0 million of available borrowings, including:

an unsecured revolving credit facility with a lender commitment of $600.0 million that replaced our existing Revolving Credit Facility; and
a $125.0 million unsecured term loan, the proceeds of which we used to pay off the remaining $100.0 million outstanding under an existing unsecured term loan and pay down a portion of our Revolving Credit Facility.

23



Due to the collective effect of our 2022 activity, we:

funded $283 million in development costs; and
ended the year with:
$389.0 million in borrowing capacity available under our Revolving Credit Facility to fund investing activities;
slightly less debt in total and as a percentage of total assets relative to year end 2021; and
no significant debt balloon payments due until 2026.

On January 10, 2023, we raised an additional $190.2 million from our sale of a 90% interest in three data center shells in Northern Virginia, resulting in a gain on sale of approximately $49 million. We retained a 10% interest in the properties through a newly-formed joint venture. We used virtually all of the proceeds from this sale to free up additional borrowing capacity available under our Revolving Credit Facility to fund future development.

In 2022 and through the date of this filing, the United States economy experienced inflationary conditions, increased interest rates, higher volatility in the debt and equity capital markets, certain supply-chain related shortages and declines in gross domestic product in the first two quarters. For us:

the above economic conditions have not significantly affected our ability to achieve expected leasing in our Defense/IT Locations, while our Regional Office properties continue to experience a challenging leasing environment that has not improved;
inflationary conditions have contributed to increased costs for certain property operating expenses and building equipment and materials, which affects our development of new properties and improvements for existing properties, although long-term contracts previously in place for much of our property operating costs have buffered our exposure to these increases to a certain extent. In addition, for:
property operating expenses, most of our leases obligate tenants to pay either their full share of a building’s operating expenses or their share to the extent such expenses exceed amounts established in their leases. These lease arrangements reduce our exposure to increases in property operating expenses;
new property development and redevelopmenttenant improvements associated with new leasing in our Defense/IT Locations, increased costs have not significantly affected our ability to achieve targeted yields on new development and new leasing of existing properties due to continued strong demand for space, discussedwhich has generally enabled us to increase rents to maintain such yields. However, continued cost increases could adversely affect our ability to continue to achieve targeted yields on future new property development and future new leasing of existing properties to the extent increases in further detail above.

market rental rates do not keep pace, which could also reduce our willingness to commence development of new properties; and
other capital improvements, the increasing cost environment could increasingly affect our willingness, or timeline, for completing such improvements;
increased interest rates have not yet significantly affected our borrowing costs due in large part to debt refinancings that we completed in 2020 and 2021. Our debt is predominantly fixed rate and in the form of long-term unsecured notes. In 2019,addition, for variable rate loans, we renewedhave used interest rate swaps to hedge the effect of interest rate increases on variable rate debt, including swaps for a $200.0 million notional amount that: fixed the one-month LIBOR interest rate in 2022 at 1.9% through December 1, 2022; and, effective February 1, 2023, fixed the one-month SOFR interest rate at 3.7% for a three-year term;
we have observed constraints in the availability of unsecured bank debt. However, we were able to complete the credit agreement on October 26, 2022 that provided for the new Revolving Credit Facility and unsecured term loan, and now have no significant debt maturing until 2026; and
supply-chain related shortages have not had a significant effect on our ability to execute our operating and development activities.

We believe that the effect of increased interest rates and capital market volatility on potential buyers could adversely affect our ability to execute plans to sell interests in properties.

For our 2022 results of operations:

diluted earnings per share increased 125.0% and net income increased $97.2 million, or 119.2%, relative to 2021 due primarily to lower debt extinguishment losses that were offset in part by lower gains from sales of properties;
diluted funds from operations per share adjusted for comparability increased 3.1% and the numerator for that measure increased $8.6 million, or 3.3%, relative to 2021, much of which was attributable to lower interest expense;
net operating income (“NOI”) from real estate operations, our segment performance measure, increased $1.4 million, or 0.4%, relative to 2021. This change was comprised primarily of the following:
a $20.8 million increase from newly developed properties placed in service; offset in part by
a $14.3 million decrease from sales of interests in properties (most notably, our wholesale data center sold in January 2022) and;
24



a $5.3 million decrease from our Same Properties attributable primarily to decreased occupancy in our Regional Office segment.

Additional disclosure comparing our 2022 and 2021 results of operations is provided below.

We discuss significant factors contributing to changes in our net income between 2022 and 2021 in the section below entitled “Results of Operations.” In addition, the section below entitled “Liquidity and Capital Resources” includes discussions of, among other things:

how we expect to generate and obtain cash for short and long-term capital needs; and
material cash requirements for known contractual and other obligations.

We refer to the measures “annualized rental revenue” and “tenant retention rate” 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 on 1.9 millionas of a point in time (ignoring free rent then in effect and rent associated with tenant funded landlord assets). Our computation of annualized rental revenue excludes the effect of lease incentives. 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 and segment analysis. Tenant retention rate is a measure we use that represents the percentage of square feet representing 76.7% ofrenewed in a period relative to the total square footage of our lease expirations (includingfeet scheduled to expire in that period; we include the effect of early renewals)renewals in this measure.

We also refer to the measures “cash rents”, “straight-line rents”, and “committed costs” in the “Occupancy and Leasing” section of the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of this Annual Report on Form 10-K. Cash rents include monthly contractual base rent (ignoring rent abatements and rent associated with tenant funded landlord assets) multiplied by 12, plus estimated annualized expense reimbursements (as of lease commencement for new or renewed leases or as of lease expiration for expiring leases). The annualizedStraight-line rents includes annual minimum rents, net of these renewals (totaling $30.88 per square foot) decreasedabatements and lease incentives and excluding rent associated with tenant funded landlord assets, on average by approximately 5.8%a straight-line basis over the term of the lease, and estimated annual expense reimbursements (as of lease commencement for new or renewed leases or as of lease expiration for expiring leases). We believe that cash rents and straight-line rents are useful measures for evaluating the GAAP rents (totaling $31.15 per square foot) decreased on average by approximately 0.3%rental rates of our leasing activity, including changes in such rates relative to the leasesrates that may have been previously in place, with cash rents serving as a measure to evaluate rents at the time rent payments commence, and straight-line rents serving as a measure to evaluate rents over lease terms. Committed costs includes tenant improvement allowances (excluding tenant funded landlord assets), leasing commissions and estimated turn key costs and excludes lease incentives; we believe this is a useful measure for the space. The renewed leases had a weighted average lease term of approximately 4.1 years, with average rent escalations per year of 2.4%, and the per annum average estimated tenant improvements and leaseevaluating our costs associated with completingobtaining new leases.

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 leasing was approximately $2.53 per square foot.portion attributable to our ownership interest.

Critical Accounting Estimates

A summary of our significant accounting policies is provided in Note 2 to our consolidated financial statements. The decreasefollowing section is a summary of certain aspects of those accounting policies involving estimates or assumptions that (1) involve a significant level of estimation uncertainty and (2) have had or are reasonably likely to have a material impact on our financial condition or results of operations. It is possible that the use of different reasonable estimates or assumptions could result in averagematerially 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 Lessor

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 (with defined rent escalations upon renewal), and/or provide for early termination rights. Applicable accounting guidance requires us to recognize minimum rental payments on operating leases, net of rent abatements, on a straight-line basis over the term of each lease. We estimate a tenant’s lease term at the lease commencement date and do not subsequently reassess such term unless the lease is modified. When estimating a tenant’s lease term, 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 to the tenant based on any existing contract, asset, entity or market-based factors associated with 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 tenant vacating or discontinuing use of the leased property. For most of our leases with the USG, our estimates of lease term conclude 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. As a result, our recognition of minimum rents on renewals wasthese leases includes the effect of annual rent escalations over our estimate of the lease term (including on one-year renewal options) and our depreciation and amortization of costs incurred on these leases is recognized over the lease term. An over-estimate of the term of these leases by us 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. We had no significant USG leases with lease terms determined to have been over-estimated during the reporting periods included herein.

Impairment of Long-Lived Assets

We assess the asset groups associated with each of our properties 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 recoverability analysis for such asset groups. If and when our plans change for a property, 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. In our accounting for impairment of long-lived assets, we estimate property fair values based on contract prices, indicative bids, discounted cash flow analyses or comparable sales analyses. We estimate cash flows used in performing impairment analyses based on our plans for the property and our views of market and economic conditions. Our 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. Our determination of appropriate capitalization or discount rates for use in estimating property fair values 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.

Since 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, decisions by us 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. Our 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.

Historically, future market rental and occupancy rates have tended to be the most variable assumption in our impairment analyses of properties to be held and used; while changes in these assumptions can significantly affect our estimates of property undiscounted future cash flows in our recoverability analyses, such changes historically have not usually resulted in impairment losses since the resulting recoverability analyses still have tended to exceed the carrying value of the property asset groups. Historically, our recognition of impairment losses has most often occurred due to changes in our estimates of future cash flows resulting from a change in our plans for a property, such as a decision by us to sell or shorten our expected holding period for a property or to not develop a property. Changes in the estimated future cash flows due to changes in our plans for a property or significant changes in our views regarding property market and economic conditions and/or our ability to obtain development rights could result in recognition of impairment losses that could be substantial.

The changes in revenue concentration reflected above between year end 2021 and 2022 were attributable primarily to per annum rent escalation termsthe effect of the previous leases that increased rents over the lease terms by amounts exceeding the increasesoccupied properties placed in the applicable market rental rates.

In 2019, we also completed leasing on 784,000 square feet of vacant space. The annualized rents of this leasing totaled $29.46 per square footservice in 2022, most notably for Redstone Arsenal and the GAAP rents totaled $29.81 per square foot; these leases had a weighted average lease term of approximately 6.4 years, with average rent escalations per year of 2.4%, and the per annum average estimated tenant improvements and lease costs associated with completing this leasing was approximately $6.77 per square foot.



Wholesale Data Center Shells, and lower occupancy for our Regional Office properties.

Our 19.25 megawatt wholesale data center was 76.9% leased as of December 31, 2019 and 87.6% leased as of December 31, 2018. Based on known tenant downsizings, we expect that the leased percentage of this property will decline to approximately 70% (or 13.6 megawatts) by July 2020. We are negotiating the renewal of a lease for 11.25 megawatts that is scheduled to expire in August 2020.

Overview

In 2022, we:

achieved strong tenant retention and vacant space leasing driven by high leasing demand for space in our large concentration of Defense/IT Locations, which more than offset the effect of lagging demand in our Regional Office properties;
placed into service our second highest annual total of newly developed square feet on record, all in our Defense/IT Locations;
ended the year with additional new Defense/IT Locations under development that were substantially pre-leased;
raised capital from property dispositions, including from our wholesale data center, to create borrowing capacity available to fund development of new Defense/IT Locations; and
refinanced our Revolving Credit Facility and an unsecured term loan, after which we had no significant remaining debt maturing until 2026.

We leased 3.0 million square feet in 2022 in our portfolio, which ended the year 92.7% occupied and 95.2% leased. This leasing was highlighted by a strong portfolio-wide retention rate of 72.1% and our highest annual vacancy leasing volume in 12 years.

Our leasing performance in 2022 was driven by the strength of our Defense/IT Locations, which represented 89.7% of our annualized rental revenues and 90.7% of our square feet as of December 31, 2022. This segment ended the year 94.1% occupied and 96.7% leased, representative of high utilization rates and slightly increased relative to year end 2021, due in large part to:

vacant space leasing of 719,000 square feet;
placing into service 1.3 million square feet in nine newly developed properties that were 99% leased; and
renewing 78.8% of the square feet scheduled to expire during the year.

As of December 31, 2022, this segment had an additional 1.0 million square feet under development that were 85% leased, which included 476,000 in development leasing completed in 2022. We believe that this segment has strongly benefited from continued:

bipartisan support for increased funding of our national defense. We believe that successive increases in defense spending since 2016, including, most recently, in the Fiscal 2023 National Defense Authorization Act, coupled with the absence of extended delays in defense appropriations legislation in recent years, 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 for an existing customer in Northern Virginia, the largest data center market in the world. As of year end, we held land that we believe would accommodate development of three additional data center shells totaling 647,000 square feet.

Since demand for this segment is driven by, and correlated with, national security spending, we believe it has been less susceptible to the effects of conditions in the overall economy in recent years than typical office properties, and we fully expect that strong demand will continue to benefit this segment well into 2024.

The strong leasing performance in our Defense/IT Locations in 2022 more than offset the effect of lagging demand in our Regional Office segment, which has experienced a challenging leasing environment since 2020 that has not improved. Our Regional Office segment ended the year 79.0% occupied and 80.8% leased, both decreases of approximately 10% relative to year end 2021. These decreases are attributable to a 23.8% renewal rate and minimal vacancy leasing in 2022. We believe that demand for space in Regional Office Properties is more correlated to changes in conditions in the overall economy than our Defense/IT Locations.

As of December 31, 2022, we had scheduled lease expirations for 1.7 million square feet in 2023, representing 8.0% of our total occupied square feet and 9.8% of our total annualized rental revenue, including:

1.5 million square feet in our Defense/IT Locations segment, a high proportion of which we expect to renew; and
170,000 square feet in our Regional Office segment, most of which we do not expect to renew.

Please refer to the section below entitled “Occupancy and Leasing” for additional related disclosure.

We raised $282.8 million in capital from sales of property interests, including:

$222.5 million from our sale of 9651 Hornbaker Road in Manassas, Virginia, our largest real estate investment (in terms of book value) and only property in our Wholesale Data Center reportable segment, on January 25, 2022, resulting in a gain on sale of $28.6 million; and
$60.3 million from our sale of a 90% interest in two data center shells in Northern Virginia on December 14, 2022, resulting in a gain on sale of $19.2 million. We retained a 10% interest in the properties through a newly-formed joint venture.

We used substantially all of the proceeds from these sales to pay down debt, including our Revolving Credit Facility and an unsecured term loan, in order to free up borrowing capacity available to fund development activities.

We refinanced our only significant 2022 and 2023 debt maturities on October 26, 2022, when we entered into a credit agreement with a group of lenders that provided for an aggregate of $725.0 million of available borrowings, including:

an unsecured revolving credit facility with a lender commitment of $600.0 million that replaced our existing Revolving Credit Facility; and
a $125.0 million unsecured term loan, the proceeds of which we used to pay off the remaining $100.0 million outstanding under an existing unsecured term loan and pay down a portion of our Revolving Credit Facility.

23



Due to the collective effect of our 2022 activity, we:

funded $283 million in development costs; and
ended the year with:
$389.0 million in borrowing capacity available under our Revolving Credit Facility to fund investing activities;
slightly less debt in total and as a percentage of total assets relative to year end 2021; and
no significant debt balloon payments due until 2026.

On January 10, 2023, we raised an additional $190.2 million from our sale of a 90% interest in three data center shells in Northern Virginia, resulting in a gain on sale of approximately $49 million. We retained a 10% interest in the properties through a newly-formed joint venture. We used virtually all of the proceeds from this sale to free up additional borrowing capacity available under our Revolving Credit Facility to fund future development.

In 2022 and through the date of this filing, the United States economy experienced inflationary conditions, increased interest rates, higher volatility in the debt and equity capital markets, certain supply-chain related shortages and declines in gross domestic product in the first two quarters. For us:

the above economic conditions have not significantly affected our ability to achieve expected leasing in our Defense/IT Locations, while our Regional Office properties continue to experience a challenging leasing environment that has not improved;
inflationary conditions have contributed to increased costs for certain property operating expenses and building equipment and materials, which affects our development of new properties and improvements for existing properties, although long-term contracts previously in place for much of our property operating costs have buffered our exposure to these increases to a certain extent. In addition, for:
property operating expenses, most of our leases obligate tenants to pay either their full share of a building’s operating expenses or their share to the extent such expenses exceed amounts established in their leases. These lease arrangements reduce our exposure to increases in property operating expenses;
new property development and tenant improvements associated with new leasing in our Defense/IT Locations, increased costs have not significantly affected our ability to achieve targeted yields on new development and new leasing of existing properties due to continued strong demand for space, which has generally enabled us to increase rents to maintain such yields. However, continued cost increases could adversely affect our ability to continue to achieve targeted yields on future new property development and future new leasing of existing properties to the extent increases in market rental rates do not keep pace, which could also reduce our willingness to commence development of new properties; and
other capital improvements, the increasing cost environment could increasingly affect our willingness, or timeline, for completing such improvements;
increased interest rates have not yet significantly affected our borrowing costs due in large part to debt refinancings that we completed in 2020 and 2021. Our debt is predominantly fixed rate and in the form of long-term unsecured notes. In addition, for variable rate loans, we have used interest rate swaps to hedge the effect of interest rate increases on variable rate debt, including swaps for a $200.0 million notional amount that: fixed the one-month LIBOR interest rate in 2022 at 1.9% through December 1, 2022; and, effective February 1, 2023, fixed the one-month SOFR interest rate at 3.7% for a three-year term;
we have observed constraints in the availability of unsecured bank debt. However, we were able to complete the credit agreement on October 26, 2022 that provided for the new Revolving Credit Facility and unsecured term loan, and now have no significant debt maturing until 2026; and
supply-chain related shortages have not had a significant effect on our ability to execute our operating and development activities.

We believe that the effect of increased interest rates and capital market volatility on potential buyers could adversely affect our ability to execute plans to sell interests in properties.

For our 2022 results of operations:

diluted earnings per share increased 125.0% and net income increased $97.2 million, or 119.2%, relative to 2021 due primarily to lower debt extinguishment losses that were offset in part by lower gains from sales of properties;
diluted funds from operations per share adjusted for comparability increased 3.1% and the numerator for that measure increased $8.6 million, or 3.3%, relative to 2021, much of which was attributable to lower interest expense;
net operating income (“NOI”) from real estate operations, our segment performance measure, increased $1.4 million, or 0.4%, relative to 2021. This change was comprised primarily of the following:
a $20.8 million increase from newly developed properties placed in service; offset in part by
a $14.3 million decrease from sales of interests in properties (most notably, our wholesale data center sold in January 2022) and;
24



a $5.3 million decrease from our Same Properties attributable primarily to decreased occupancy in our Regional Office segment.

Additional disclosure comparing our 2022 and 2021 results of operations is provided below.

We discuss significant factors contributing to changes in our net income between 2022 and 2021 in the section below entitled “Results of Operations.” In addition, the section below entitled “Liquidity and Capital Resources” includes discussions of, among other things:

how we expect to generate and obtain cash for short and long-term capital needs; and
material cash requirements for known contractual and other obligations.

We refer to the measures “annualized rental revenue” and “tenant retention rate” 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 and rent associated with tenant funded landlord assets). Our computation of annualized rental revenue excludes the effect of lease incentives. 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 and segment analysis. Tenant retention rate is a measure we use that represents the percentage of square feet renewed in a period relative to the total square feet scheduled to expire in that period; we include the effect of early renewals in this measure.

We also refer to the measures “cash rents”, “straight-line rents”, and “committed costs” in the “Occupancy and Leasing” section of the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of this Annual Report on Form 10-K. Cash rents include monthly contractual base rent (ignoring rent abatements and rent associated with tenant funded landlord assets) multiplied by 12, plus estimated annualized expense reimbursements (as of lease commencement for new or renewed leases or as of lease expiration for expiring leases). Straight-line rents includes annual minimum rents, net of abatements and lease incentives and excluding rent associated with tenant funded landlord assets, on a straight-line basis over the term of the lease, and estimated annual expense reimbursements (as of lease commencement for new or renewed leases or as of lease expiration for expiring leases). We believe that cash rents and straight-line rents are useful measures for evaluating the rental rates of our leasing activity, including changes in such rates relative to rates that may have been previously in place, with cash rents serving as a measure to evaluate rents at the time rent payments commence, and straight-line rents serving as a measure to evaluate rents over lease terms. Committed costs includes tenant improvement allowances (excluding tenant funded landlord assets), leasing commissions and estimated turn key costs and excludes lease incentives; we believe this is a useful measure for evaluating our costs associated with obtaining new leases.

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.

Critical Accounting 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 or assumptions that (1) involve a significant level of estimation uncertainty and (2) have had or are reasonably likely to have a material impact on our financial condition or results of operations. It is possible that the use of different reasonable estimates or assumptions 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 Lessor

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 (with defined rent escalations upon renewal), and/or provide for early termination rights. Applicable accounting guidance requires us to recognize minimum rental payments on operating leases, net of rent abatements, on a straight-line basis over the term of each lease. We estimate a tenant’s lease term at the lease commencement date and do not subsequently reassess such term unless the lease is modified. When estimating a tenant’s lease term, 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 to the tenant based on any existing contract, asset, entity or market-based factors associated with 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 tenant vacating or discontinuing use of the leased property. For most of our leases with the USG, our estimates of lease term conclude 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. As a result, our recognition of minimum rents on these leases includes the effect of annual rent escalations over our estimate of the lease term (including on one-year renewal options) and our depreciation and amortization of costs incurred on these leases is recognized over the lease term. An over-estimate of the term of these leases by us 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. We had no significant USG leases with lease terms determined to have been over-estimated during the reporting periods included herein.

Impairment of Long-Lived Assets

We assess the asset groups associated with each of our properties 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 recoverability analysis for such asset groups. If and when our plans change for a property, 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. In our accounting for impairment of long-lived assets, we estimate property fair values based on contract prices, indicative bids, discounted cash flow analyses or comparable sales analyses. We estimate cash flows used in performing impairment analyses based on our plans for the property and our views of market and economic conditions. Our 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. Our determination of appropriate capitalization or discount rates for use in estimating property fair values 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.

Since 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, decisions by us 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. Our 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.

Historically, future market rental and occupancy rates have tended to be the most variable assumption in our impairment analyses of properties to be held and used; while changes in these assumptions can significantly affect our estimates of property undiscounted future cash flows in our recoverability analyses, such changes historically have not usually resulted in impairment losses since the resulting recoverability analyses still have tended to exceed the carrying value of the property asset groups. Historically, our recognition of impairment losses has most often occurred due to changes in our estimates of future cash flows resulting from a change in our plans for a property, such as a decision by us to sell or shorten our expected holding period for a property or to not develop a property. Changes in the estimated future cash flows due to changes in our plans for a property or significant changes in our views regarding property market and economic conditions and/or our ability to obtain development rights could result in recognition of impairment losses that could be substantial.

With regard to changes in occupancy from December 31, 2021 to December 31, 2022:

Fort Meade/BW Corridor: Increase was due primarily to occupancy from vacant space leasing in a number of properties in this sub-segment;
Navy Support: Decreased despite its 82.8% tenant retention rate in 2022 due to minimal leasing of vacant space. As of December 31, 2022 we had scheduled lease expirations in 2023 for 198,000 square feet, or 17.4%, of this sub-segment’s occupied square feet, most of which we expect to renew;
Redstone Arsenal: 2021 and 2022 year end occupancy included the effect of a 121,000 square foot property vacated by its tenant in late 2021 that we leased in 2022 for occupancy in 2023. Occupancy in this sub-segment will increase in 2023 when the lease for this space commences.
Regional Office: Decreased due to vacated space resulting from its 23.8% tenant retention rate and minimal leasing of vacant space. This segment included properties in Baltimore City, Tysons Corner, Virginia and Washington, D.C. This sub-segment has experienced a challenging leasing environment since 2020 that has not improved. As of December 31, 2022 we had scheduled lease expirations in 2023 for 170,000 square feet, or 10.9%, of this segment’s occupied square feet, most of which we do not expect to renew; and
Other: Included two properties totaling 157,000 square feet in Aberdeen, Maryland.

In 2022, we leased 3.0 million square feet, including 476,000 square feet of development space in Defense/IT Locations, with weighted average lease terms of 13.3 years.

In 2022, we renewed leases on 1.7 million square feet, representing a tenant retention rate of 72.1%. Most of these lease renewals were for our Defense/IT Locations, which had a retention rate of 78.8%, while our Regional Office segment had a retention rate of 23.8%. The cash rents for our renewals (totaling $31.69 per square foot) decreased on average by approximately 2.0% and the straight-line rents (totaling $31.45 per square foot) increased on average by approximately 3.1% relative to the leases previously in place for the space. The renewed leases had a weighted average lease term of approximately 3.6 years, with average escalations per year of 2.5%, and the per annum average committed costs associated with completing the leasing was approximately $2.96 per square foot. The decrease in cash 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 2022, we also completed leasing on 801,000 square feet of vacant space, predominantly for Defense/IT Locations. The cash rents of this leasing totaled $28.90 per square foot and the straight-line rents totaled $29.59 per square foot; these leases had a weighted average lease term of approximately 7.3 years, with average escalations per year of 2.7%, and the per annum average committed costs associated with completing this leasing was approximately $8.81 per square foot.

NOI from real estate operations$362,304 $360,870 

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 Properties section of Note 2 of the consolidated financial statements entitled “Properties”;statements;
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.center that we sold on January 25, 2022.

 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.
 
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 from continuing operations reported on the consolidated statements of operations of COPT and subsidiaries is provided in Note 1615 to our consolidated financial statements.

Our Same Properties pool consisted of 147174 properties, comprising 82.9%86.9% of our office and data center shell portfolio’s square footage as of December 31, 2019.2022. This pool of properties changed from the pool used for purposes of comparing 20182021 and 20172020 in our 20182021 Annual Report on Form 10-K due to: theto the: addition of nine properties placed in service and 100% operational on or before

Regarding the changes in June 2019 and two in December 2019) and one property that was removed from service in October 2019.



As reflected above, our increase in Same Properties NOI from real estate operations was due primarily to increased lease revenuereported above:

the decrease for our Defense/IT LocationsSame Properties pool was attributable to our Regional Office segment, in which the average occupancy rate decreased from 92.7% to 83.0% due mostly to the scheduled lease expiration of a 140,000 square foot space. The increase in operating expenses for our Same Properties was due in large part to higher occupancy.increased rates for utilities and certain cleaning and maintenance contracts, much of which was recovered from tenants under existing lease structures;

Our NOI from developed and redeveloped properties placed in service included 14reflects the effect of 16 properties and land under a long-term contract placed in service in 20182022 and 2019, while our dispositions included our2021;
the decrease in ownership in the ninefor wholesale data center shells includedresulted from our sale of the property on January 25, 2022; and

Our provision for credit losses of $686,000 in 2019 and $339,000 in 2018 was included in revenue from real estate operations and property operating expenses, respectively, representing 0.13% and 0.07%effect of our revenue from real estate operations for the respective years.sale of 90% of our interests in two data shells in 2022 and two in 2021.

Construction contract and other service revenuerevenues and expenses increased in 2022 due primarily to a higher volume of construction activity in connection with severalfor one 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,Our general, administrative and leasing expenses increased in large part due to: higher compensation and related expenses and legal and professional expenses; and lowerexpense are net of amounts capitalized compensation resulting from our adoption of lease accounting guidance in 2019 under which we no longer defer recognition of non-incremental leasing costs.

We capitalizefor compensation and indirect costs associated with properties, or portions thereof, undergoing development or redevelopment activities. We also, prior to our adoption of lease accounting guidance in 2019, capitalized compensation costs associated with obtaining new tenant leases or extending existing tenants. Our capitalized compensation and indirect costs totaled $10.1$10.7 million in 20192022 and $11.1$11.0 million in 2018.2021.

Gain on salesSales of real estateReal Estate


The gainGain on sales of real estate in 20192022 was due to our sale of a 90% interest in ninetwo data center shell properties. Gain on sales of real estate in 2021 included primarily $40.2 million from our sale of a 90% interest in two data center shell properties and $25.9 million from our sale of a property in our data center shells sub-segment that was previously removed from service. For the sales of 90% interests in properties in 2022 and 2021, we retained a 10% interest in the properties through the BREIT-COPT transactions.unconsolidated real estate joint ventures.

Loss on Extinguishment of Debt

The decrease in loss on early extinguishment of debt was attributable primarily to unsecured senior notes refinancings that occurred in 2021.

Discontinued Operations

Discontinued operations includes our wholesale data center, including $28.6 million in gain from its sale on January 25, 2022.

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 and investments in UJVs (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 National Association of Real Estate Investment Trusts (“Nareit”)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 (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) issuance costs associated with redeemed preferred shares, (3) income attributable to noncontrolling interests through ownership of preferred units in the Operating Partnership or interests in other consolidated entities not owned by us, (4)(3) depreciation and amortization allocable to noncontrolling interests in other consolidated entities and (5)(4) Basic FFO allocable to share-based compensation awards. 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.
 
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 excludeexclude: operating property acquisition costs; gain or loss on early extinguishment of debt; FFO associated with properties securingthat secured non-recourse debt on which we have defaulted and, which we havesubsequently, extinguished or expect to extinguish, via conveyance of such

properties including(including property NOI, interest expense and gains on debt extinguishment (discussed further below)extinguishment); loss on interest rate derivatives; and, for periods prior to October 1, 2022, demolition costs on redevelopment and nonrecurring improvements;improvements and executive transition costs; issuance costs associated with redeemed preferred shares; and certain other expenses that we believe are not closely correlated with our operating performance.costs. 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. The adjustment


for FFO associated with properties securing non-recourse debt on which we have defaulted pertains to the periods subsequent to our default on one loan’s payment terms, which was the result of our decision to not support payments on the loan since the estimated fair value of the properties was less than the loan balance. While we continued as the legal owner of the properties during this period up until the transfer of ownership, all cash flows produced by them went directly to the lender and we did not fund any debt service shortfalls, which included incremental additional interest under the default rate of $5.3 million in 2015. 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 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.

We adopted, retrospectively effective January 1, 2019, Nareit’s 2018 Whitepaper Restatement, which changed the prior definition of FFO to also exclude gains on sales and impairment losses of properties other than previously depreciated operating properties, net of associated income tax. This adoption affected our reporting for FFO, Basic FFO, Diluted FFO and Diluted FFO per share.

 Cash Flows
 
Net cash flow from operating activities increased $48.1$16.7 million, or 6.7%, from 20182021 to 2019 due2022 attributable primarily toto: additional interest income received on notes receivable from the City of Huntsville; and lower interest expense paid resulting from debt refinancings completed in 2021 that reduced our paymentborrowing rates on unsecured senior notes and affected the timing of our interest payments; offset in 2018part by a decrease associated with the timing of cash flows from third-party construction costs on a contract that the customer pre-funded to us in prior years.projects.

Net cash flow used in investing activities decreased $94.9$119.5 million from 20182021 to 20192022 due primarily to $309.6$138.0 million in additional proceeds from property dispositionsales in 2022, which included proceeds mostly from our sale in 2019 of a 90% interest in properties that was offset in part by a $234.5 million increase in cash outlays for development and redevelopment in 2019.wholesale data center sale.

Supplemental Guarantor Information

As of $15.4 million.

LiquidityDecember 31, 2022, COPLP had several series of unsecured senior notes outstanding that were issued in transactions registered with the SEC under the Securities Act of 1933, as amended. These notes are COPLP’s direct, senior unsecured and Capital Resourcesunsubordinated obligations and rank equally in right of COPT
COPLP is the entity through which COPT, the sole general partner of COPLP, conducts almostpayment with all of its operationsCOPLP’s existing and owns almostfuture senior unsecured and unsubordinated indebtedness. However, these notes are effectively subordinated in right of payment to COPLP’s existing and future secured indebtedness. The notes are also effectively subordinated in right of payment to all existing and future liabilities and other indebtedness, whether secured or unsecured, of its assets.COPLP's subsidiaries. COPT occasionally issues public equity but does not otherwise generate any capital itselffully and unconditionally guarantees COPLP’s obligations under these notes. COPT’s guarantees of these notes are senior unsecured obligations that rank equally in right of payment with other senior unsecured obligations of, or conduct any business itself, other than incurring certain expenses in operating as a public company which are fully reimbursedguarantees by, COPLP.COPT. COPT itself does not hold any indebtedness, and its only material asset is its ownershipinvestment in COPLP.

As permitted under Rule 13-01(a)(4)(vi), we do not provide summarized financial information for the Operating Partnership since: the assets, liabilities, and results of partnership interestsoperations of COPLP. COPT’s principal funding requirement is the paymentCompany and the Operating Partnership are not materially different than the corresponding amounts presented in the consolidated financial statements of dividends on its commonthe Company; and preferred shares. COPT’s principal sourcewe believe that inclusion of funding for its dividend payments is distributions it receives from COPLP.such summarized financial information would be repetitive and not provide incremental value to investors.

Liquidity and Capital Resources

As of December 31, 2019, COPT owned 98.7% of the outstanding common units in COPLP; the remaining common units and all of the outstanding preferred units were owned by third parties. 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.

As discussed further below,2022, 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 working capital needs, 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, 2019, COPLP had $14.7$12.3 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 for joint venture financing. 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


We have a Revolving Credit Facility with a maximum borrowing capacity of $600.0 million. We use this facility to initially financefund much of itsthe cash requirements from our investing activities.  COPLPactivities, including property development/redevelopment costs, as well as certain debt balloon payments due upon maturity.  We then subsequently payspay down the facility using cash available from operations and proceeds from long-term borrowings, 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,October 2026 and may be extended by two six-month periods at COPLP’sour option, provided that there is no default under the facility and COPLP payswe pay an extension fee of 0.075%0.0625% of the total availability under the facility for each extension period. As of December 31, 2019, the maximumOur available borrowing capacity under thisthe facility totaled $800.0$389.0 million as of which $623.0 million was available.December 31, 2022, and on January 10, 2023, we further increased our borrowing capacity using proceeds from our sale of a 90% interest in three data center shells for $190.2 million.


Our senior unsecured debt is rated investment grade by the three major rating agencies. We aim to maintain 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. We also use secured nonrecourse debt from institutional lenders and banks primarily for joint venture financings. In addition, we periodically raise equity when we access the public equity markets by issuing common shares and, to a lesser extent, preferred shares.
COPT has
We have a program in place under which itwe 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, COPTwe may also, at itsour 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 issuing the shares and receiving the sale proceeds from the sale until a later date.

We believe that COPLP’sour liquidity and capital resources are adequate for itsour near-term and longer-term requirements without necessitating property sales. However, we may dispose of interests in properties opportunistically or when capital marketsmarket conditions otherwise warrant.

We expect to use cash flow from operations in 2023 and annually thereafter for the foreseeable future to fund theall of these cash requirements except for debt balloon payments due upon maturity and a portion of property development/redevelopment costs.

In 2023, we expect to spend $250 million to $275 million on development costs, initiallymost of which was contractually obligated as of December 31, 2022; we expect to fund these cash requirements using, in part, remaining cash flow from operations, with the balance funded primarily using borrowings under our Revolving Credit Facility.

Beyond 2023, we expect to continue to actively develop and redevelop properties and fund improvements to existing operating properties using, in part, remaining cash flow from operating activities.operations, with the balance funded primarily using borrowings under our Revolving Credit Facility, at least initially.


We provide disclosure in our consolidated financial statements on our future lessee obligations (expected to be funded primarily by cash flow from operations) in Note 5 and future debt obligations (expected to be refinanced by new debt borrowings or funded by future equity issuances and/or sales of interests in properties) in Note 10.

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, 2019,2022, we were compliant with these covenants.
Off-Balance Sheet Arrangements

We had no material off-balance sheet arrangements during 2019.

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.

Interest expense in 20192022 was moreless sensitive to a change in interest rates than 20182021 due primarily to our having a higherlower average variable-rate debt balance in 2019.2022 including the effect of interest rate derivatives in place.

Corporate Office Properties Trust Managements 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, 2019.2022. 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, 20192022 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, 20192022 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, 20192022 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

We also have audited the Company'sCompany’s internal control over financial reporting as of December 31, 2019,2022, 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, 20192022 and 2018,2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 20192022 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, 2019,2022, 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 the board of 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.

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 from continuing operations for the year ended December 31, 20192022 was $522.5$580.2 million and a significant portion of the Company’s leases are with the United States Government, which represented 25%27% of the fixed lease revenues for the year ended December 31, 2019.2022. 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 StatedStates 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, such asrelated 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.

We also have audited the Operating Partnership’s internal control over financial reporting as of December 31, 2019, 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, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019 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, 2019, 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.

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, 2019 was $522.5 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, 2019. The majority of United States Government leases contain one-year renewal options and/or provide for early termination rights.

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 Stated 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, such as 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.

Notes to Consolidated Financial Statements



1.    Organization
 
Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company”, “we” or “us”) 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-likeurban submarkets in the Greater Washington, DC/Baltimore region with durable Class-A office fundamentals and characteristics (“Regional Office”). As of December 31, 2019,2022, our properties included the following (all references to number of properties, square footage acres and megawattsacres are unaudited):

170194 properties totaling 19.223.0 million square feet comprised of 15.417.7 million square feet in 148166 office properties and 3.75.3 million square feet in 2228 single-tenant data center shell properties (“data center shells”).shells. We owned 1521 of these data center shells through unconsolidated real estate joint ventures;
a wholesale data center with a critical load of 19.25 megawatts;
14seven properties under development or redevelopment (10(five office properties and 4two data center shells), including two partially-operational properties, that we estimate will total approximately 2.51.0 million square feet upon completion, including 1 partially-operational property;completion; and
approximately 900710 acres of land controlled for future development that we believe could be developed into approximately 11.39.5 million square feet and 43 acres of other land.

We conduct almost all of our operations and own almost all of our assets through our operating partnership, Corporate Office Properties, L.P. (“COPLP”) and subsidiaries (collectively, the “Operating Partnership”), of which COPT is the sole general partner. 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, 2019,2022, COPT owned 98.7%98.0% of the outstanding COPLP common units (“common units”); the remaining common units and all of the outstanding COPLPthere were no preferred units (“preferred units”) were owned by third parties.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. In the case of any series of preferred units held by COPT, there would be a series of preferred shares of beneficial interest (“preferred shares”) in COPT that is equivalent in number and carries substantially the same terms as such series of COPLP preferred units. 

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 COPTThese 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.
 

F-20


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

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.
 
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.

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.

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 atas of the dates of the financial statements;
the disclosure of contingent assets and liabilities atas 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 for impairment, 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. The predevelopment stage of the development or redevelopment of an operating property includes efforts and related costs to secure land control and zoning, evaluate feasibility and complete other initial tasks that are essential to development.

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 andor redevelopment activities. In capitalizing interest expense, if there is a specific borrowing for a property undergoing development andor 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 andor redeveloped properties as they become operational. For newly-developed properties, we classify improvements provided under the terms of a lease that are deemed to be landlord assets (as discussed further below) as new building development costs.

Most of our leases involveprovide 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 associated with such improvements over the shorter of theestimated useful lifelives of the assets or the term of the lease andas discussed below. We recognize any payments from the tenant for such assets as rentallease 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:including whether the improvementseconomic 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; whethermay be altered or removed by the tenant is permitted to alter or remove the improvements without our consent or without compensating us for any lost fair value; whether the ownership of the

improvements remainsremain, with us or remains with the tenant at the end of the lease term; and whether the economic substance of the lease terms is properly reflected.

term.

We depreciate our fixed assets using the straight-line method over their estimated useful lives as follows:
Estimated Useful Lives
Buildings and building improvements10-40 years
Land improvements10-20 years
Tenant improvements on operating propertiesShorter of remaining useful lives of assets or related lease term
Equipment and personal property3-10 years

For discontinued operations, we classify for all periods presented the associatedassociated: assets as held for sale on our consolidated balance sheets; and results of operations as discontinued operations. We had no properties newly classifiedoperations on our consolidated statements of operations (including interest expense on debt specifically identifiable to such components).

For periods in which a property not reported as discontinued operations inis classified as held for sale, we classify the last three years.assets of the property’s asset group as held for sale on our consolidated balance sheets.

Sales of Interests in Properties

We recognize gains from sales of consolidated interests in properties using the full accrual method, provided that various criteria relating to the termswhen we transfer control of sale and any subsequent involvement by us with the real estate sold are met.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. Changesplans; as a result, changes in holding periods may require us to recognize significant 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 bookcarrying value of the property’s asset group, we recognize an impairment loss equal to the difference and reduce the net bookcarrying value of the property’s asset group. 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.

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 based on the valuation performed 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 estimated interest rate which reflectsreflective of 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,spaces, measured over a period equal to the remaining non-cancelable termterms of the lease.respective leases. The capitalized above- and below-market lease values are amortized as adjustments to rentallease 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 additional income to be realized includes carrying costs, such as real estate taxes, insurance and other operating expenses, and revenues during the expected lease-up periods considering current market conditions. 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.

Property Right-of-UseLeased Assets, as a Lessee

We lease land underlying certain properties that we are operating or developing from third parties. In determining operatingrecognize right-of-use assets and lease liabilities for our existingland and other assets leased by us from third parties for terms of at least one year. We recognize lease expense over lease terms on a straight-line basis for operating leases upon our adoption of the newand on an effective interest method basis for finance leases. In determining right-of-use assets and lease guidance discussed below, as well as for new operating leases in the current period,liabilities, we were required to estimate an appropriate incremental borrowing rate on a fully-collateralized basis for the terms of the leases. Since the terms under our groundland leases are usually significantly longer than the terms of borrowings available to us on a fully-collateralized basis, our estimateestimates of this rate requiresrates for such leases require significant judgment, and considersconsider factors such as estimated 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 Federallyfederally insured limits at times. We have not experienced any losses inon 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.

AccountsReceivables and Deferred Rents Receivable and Investing ReceivablesCredit 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 primarily upon the payment history and credit status of the entities associated with the individual receivables. 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.

ForLease Revenue

We estimate the collectability of lease revenue ifand related accounts receivable using judgement based on the credit status and payment history of the related tenants. If we deem that collectability of revenue 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. Losses on lease revenue receivables are presented on our consolidated statements of operation with property operating expenses for years prior to

Financial Assets and Other Instruments

Effective January 1, 2019, when2020, we adopted new lease accounting guidance and as reductions in lease revenue thereafter.

A loan is impaired when it is probableFinancial Accounting Standards Board (“FASB”) that changed how we will be unable to collect all amounts due according to the existing contractual terms.  When a loan is impaired, the amount of the loss accrual is 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. Interest on impaired loans is recognized when received in cash.

Intangible Assets and Deferred Revenue on Real Estate Acquisitions

We amortize the intangiblemeasure credit losses for most financial assets and deferred revenue on real estate acquisitions discussed above as follows:certain other instruments not measured at fair value through net income from an incurred loss model to an expected loss approach. 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 and did not adjust prior comparative reporting periods. Our items within the scope of this guidance include:
Asset TypeAmortization Period

In-place lease valueRelated lease terms

We recognize the amortization of above-contract assets from unbilled construction contract revenue; 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.

off-balance sheet credit exposures.

F-14


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

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 allowance for expected credit losses reflects 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 items within the scope of this guidance 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 19).

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.

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.leases. 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.lease term.

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.early or significantly modified. 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 have also useused 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.

Effective January 1, 2018, we defer all changes in the fair value of designated cash flow hedges to AOCI or 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 the 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’sOur 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. Also included in COPLP’s consolidated noncontrolling interests are interests in several real estate entities owned directly by COPT, or a wholly owned subsidiary of COPT, that generally do not exceed 1% of interests in such entities. 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’sour consolidated balance sheets or common units on COPLP’s balance sheet.sheets. 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.

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; if 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, we would derecognize the underlying asset and recognize a net investment in the lease, but, unlike in a sales-type lease, would defer profit and amortize it as interest income over the lease term. Our leases of properties as lessor reflected herein are predominantly classified as operating leases. leases, for which the underlying asset remains on our balance sheet and is depreciated consistently with other owned assets, with income recognized as described 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 suchthe 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
F-16


Corporate Office Properties Trust and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

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 elected a practical expedient available under lease accounting guidance that enables us to combine non-lease components that otherwise would need to be accounted for under revenue accounting guidance (such as tenant reimbursements of property operating expenses) with the associated lease components for our accounting and reporting of operating lease revenue.

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 generally 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

F-26


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

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 rentallease revenue associated with thesuch 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.

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 eachassociated with a 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 whichthat 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.

Corporate Office Properties Trust and Subsidiaries
Notes to Consolidated Financial Statements (Continued)

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 fullwith an undefined 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-27


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 thean adjustment onto 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 thea 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 suchconstruction contract 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 customer invoicing is for convenience purposes, not to receive financing from our customersprovide or to provide customers withreceive financing. Additionally, the timing of transfer of theour 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 expenseexpenses 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.costs.

Share-Based Compensation
We issue 4four forms of share-based compensation: restricted COPT common shares (“restricted shares”), profit interest units (“PIUs”) (time-based and performance-based), deferred share awards (also known as restricted share units), and performance share units (also known as performance share awards) (“PSUs”) and profit interest units (“PIUs”) (time-based and performance-based). We also issued options to purchase COPT common shares (“options”) in prior years. 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 awardawards 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 (“TB-PIUs”) and deferred share awards based on the fair value of COPT common shares on the grant date. We compute the fair value of PSUsperformance-based PIUs (“PB-PIUs”) and performance-based PIUsPSUs using a Monte Carlo 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’sits adjusted taxable income to its shareholders. As a REIT, COPT generally will not be subject to Federalfederal 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 Federalfederal 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 Federalfederal 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 and preferred shares during each of the last three years was as follows:
For the Years Ended December 31,
202220212020

We distributed all of COPT’s REIT taxable income in 2019, 20182022, 2021 and 20172020 and, as a result, did not incur Federalfederal income tax in those years.

The net basis of our consolidated assets and liabilities for tax reporting purposes was approximately $52$7 million higherlower than the amount reported on our consolidated balance sheet as of December 31, 2019 which was primarily related to differences in basis for net properties, intangible assets on property acquisitions and deferred rent receivable.2022.

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, administrative and administrative expenseleasing expenses 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.

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. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. This guidance requires 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 on January 1, 2019 using a modified retrospective transition approach under whichreference rate reform activities occur. In 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 guidance effective January 1, 2019 and not adjust prior comparative reporting periods (exceptassessments of effectiveness for ourfuture 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 lease revenue discussed below). Wederivatives consistent with past presentation. In addition, in 2022 we entered into bilateral agreements with swap counterparties to transition certain interest rate swap agreements from LIBOR to SOFR; in connection with these amendments, 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 practicalan expedient that enabled us to avoidunder this guidance for changes in 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 for our rental properties (as lessor) to avoid separating non-lease components that otherwise would need to be accounted for under the recently-adopted 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 combinationcritical terms of the lease component and non-lease components as an operating lease since the lease component is the predominant component of the combined components. Below is a summary of the primary changes in our accounting and reporting that resulted from our adoption of this guidance:

Property leases in which we are the lessor:
Deferral of non-incremental leasing costs: For new or extended tenant leases, we no longer defer recognition of non-incremental leasing costs that we would have deferred under prior accounting guidance; these deferrals totaled $1.2 million in 2018 and $1.1 million in 2017.
Change in presentation of revenue: Due to our adoption of the practical expedient discussed abovehedging relationships due to reference rate reform to not separate non-lease component revenue from the associated lease component, we are aggregating revenue from our lease components and non-lease components (comprised predominantly of tenant operating expense reimbursements) into the line entitled “lease revenue.” We are reporting other revenue from our properties in the line entitled “other property revenue.” We recast prior periods for these changes in presentation.
Changes in assessment of lease revenue collectability: Changes in our assessment of lease revenue collectability that previously would have resulted in charges to bad debt expense under prior guidance are being recognized as an adjustment to rental revenue under the new guidance. Such amounts recognized by us in prior periods were not significant.
Operating expenses paid directly by tenants to third parties: Operating expenses paid directly by tenants to third parties (primarily for real estate taxes) and revenue associated with such tenant payments that would have been recognized under prior guidance will no longer be reported on our Statement of Operations. Such amounts recognized by us in prior periods were not significant.
Leases in which we are the lessee (the most significant of which are ground leases):
Balance sheet presentation of property operating lease right-of-use assets: Upon adoption on January 1, 2019, we recognized property right-of-use assets and offsetting lease liabilities for existing operating leases totaling $16 million for the present value of minimum lease payments under these leases, and also reclassified an additional $11 million in amounts previously presented elsewhere on our balance sheet in connection with these leases to the right-of-use assets. We will recognize additional right-of-use assets and lease liabilities as we enter into new operating leases.
Balance sheet presentation of property finance lease right-of-use assets: Property right-of-use assets of finance leases that previously were presented as properties under prior guidance are being presented as property finance right-of-use assets under the new guidance. As a result we reclassified $38 million in assets from properties to property finance right-of-use assets upon adoption on January 1, 2019.
Segment assets: We changed our definition of segment assets used for our reportable segments to include property right-of-use assets associated with operating properties, net of related lease liabilities.

In June 2016, the FASB issued guidance that changes how entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the current incurred loss model with an expected loss approach, resulting in a more timely recognitiondedesignation of such losses. The guidance applies to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables (excluding ones arising from operating leases), loans, held-to-maturity debt securities, net investments in leases and off-balance-sheet credit exposures (e.g. loan commitments and guarantees). Under the new guidance, we will recognize an estimate of our expected 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. Upon adoption, our most significant assets within the scope of this guidance were our investing receivables and receivables and contract assets associated with our non-USG construction contracts. We adopted this guidance effective January 1, 2020 using a modified retrospective transition approach under which we apply the guidance effective January 1, 2020, with a cumulative-effect adjustment as of such date, and do not adjust prior comparative reporting periods. Upon adoption, we recognized an allowance for expected credit losses on these assets with an offset to retained earnings that did not have a material impact on our consolidated financial statements. Following adoption, our consolidated statements of operations will reflect adjustments for any changes in our expected credit losses.

In August 2018, the FASB issued guidance that modifies disclosure requirements for fair value measurements. We adopted this guidance effective January 1, 2020. The resulting changes in disclosure will not have a material impact on our consolidated financial statements.

In August 2018, the FASB issued guidance 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. We adopted this guidance effective January 1, 2020. Our adoption of this guidance did not have a material impact on our consolidated financial statements.

hedging relationships.

3.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
F-19

Notes to Consolidated Financial Statements (Continued)

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 hasWe have a non-qualified elective deferred compensation plan for Trustees and certain members of our management team that, permitsprior 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. Effective December 31, 2019, no new investments of deferred compensation were eligible for the plan. 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’sour 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 $3.1$1.8 million as of December 31, 20192022 and $3.9$2.6 million as of December 31, 2018,2021, and is included in the line entitled “prepaid expenses and other assets, net” on COPT’sour consolidated balance sheets.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“other liabilities” on COPT’sour 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, 20192022 and 2018,2021, we assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our

F-31


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

derivatives and determined that these adjustments arewere 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 debtour senior notes (categorized within Level 21 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.  Settlement at such fair value amounts may not be possible and may not be a prudent management decision.
 
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.

2017 Nonrecurring Fair Value Measurements

As part of our closing process for each quarter in 2017, we conducted our review of our portfolio of long-lived assets to be held and used for indicators of impairment and found there to be no impairment losses in the first, second and third quarters. In the fourth quarter of 2017, our assessment of weakening leasing prospects and expected enduring vacancy in our Aberdeen, Maryland (“Aberdeen”) portfolio indicated that these properties could be impaired. We performed recovery analyses on the properties considering weakening tenant demand, high vacancy and low investor demand for office properties in the surrounding submarkets and concluded that the carrying values of these properties were not likely to be recovered from the expected undiscounted cash flows from the operation and eventual disposition of these properties. Accordingly, we recognized $9.0 million of impairment losses on the operating properties in Aberdeen (included in our Other segment). In addition, and also considering these conditions, we determined that we would not likely recover the carrying amount of land in this submarket and recognized a $4.7 million impairment loss on it. We previously recognized impairment losses on these properties in 2016. We determined that the declines in values that have occurred since the initial losses were recognized were due to declining market conditions.

For the respective quarters in 2017, we also performed recoverability analyses for our properties classified as held for sale which resultedon our consolidated balance sheets (in thousands):

2022 Dispositions and Discontinued Operations

On January 25, 2022, we sold 9651 Hornbaker Road in impairment lossesManassas, Virginia, our sole wholesale data center investment, for $222.5 million, resulting in a gain on sale of $1.6 million$28.6 million. This property, a separate reportable segment, is reported herein as discontinued operations. The table below sets forth the property’s results of operations included in the second quarterdiscontinued operations on our consolidated statements of 2017. These impairment losses were primarily on properties in White Marsh, Maryland (“White Marsh”) (included in our Regional Officeoperations and Other segments) that we reclassified to held for sale during the periodits operating and adjusted to fair value less costs to sell. These properties were sold in the third quarter of 2017.

Changes in the expected futureinvesting cash flows due to changes inincluded on our plans for specific properties (especially our expected holding period) could result in the recognitionconsolidated statements of impairment losses. In addition, because properties held for sale are carried at the lower of carrying value or estimated fair values less costs to sell, declines in their estimated fair values due to market conditions and other factors could result in the recognition of impairment losses.

We recognize a valuation allowance on our deferred tax asset if we believe that all, or some portion, of the asset may not be realized. An increase or decrease in the valuation allowance resulting from a change in circumstances that causes a change in our judgment about the realizability of our deferred tax asset is included in income. The decrease in deferred tax asset valuation allowance reflected above was due to higher projected taxable income in our TRS resulting from certain construction projects. We believe it is more likely than not that the results of future operations in our TRS will generate sufficient taxable income to realize our December 31, 20192022 net deferred tax asset.

Each of these swaps was designated as a cash flow hedge of interest rate risk except for the swap with a $50.0 million notional amount. We discontinued hedge accounting for this swap effective in December 2021 when we determined that some of its hedged forecasted transactions were probable not to occur due to our entry into a contract to sell our wholesale data center and the debt pay down expected upon completion of the sale. This resulted in our reclassification of $221,000 in losses from AOCL to interest expense in our statement of operations.

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 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.

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.

Preferred Shares

As of December 31, 2019, COPT2022, we had 25.0 million preferred shares authorized and unissued at $0.01 par value per share. In 2017, COPT redeemed all of its outstanding preferred shares, including:

the 5.600% Series K Cumulative Redeemable Preferred Shares (the “Series K Preferred Shares”) redeemed effective January 21, 2017 at a price of $50.00 per share, or $26.6 million in the aggregate, plus accrued and unpaid dividends thereon through the date of redemption. Concurrently with this redemption, COPLP redeemed its Series K Preferred Units on the same terms; and

the 7.375% Series L Cumulative Preferred Shares (the “Series L Preferred Shares”) redeemed effective June 27, 2017 at a price of $25.00 per share, or $172.5 million in the aggregate, plus accrued and unpaid dividends thereon up to but not including the date of redemption. Concurrently with this redemption, COPLP redeemed its Series L Preferred Units on the same terms. We also recognized a $6.8 million decrease to net income available to common shareholders in 2017 pertaining to the original issuance costs incurred on the shares.

Common Shares

In September 2016, COPT establishedMay 2022, we entered into an at-the-market (“ATM”) stock offering program (the “2022 ATM Program”) that replaced a similar program established in 2018 (the “2018 ATM Program”) because we replaced the registration statement under which it may, from time to time, offer and sell common shares in “at the market” stock offerings having an aggregate gross sales price of up to $200.0 million (the “2016 ATM Program”). COPT issued the following common shares under this ATM program in 2018 and 2017:

992,000 shares in 2018 at a weighted average price of $30.46 per share. Net proceeds from the shares issued totaled $29.8 million, after payment of $0.5 million in commissions to sales agents; and
591,000 shares in 2017 at a weighted average price of $33.84 per share. Net proceeds from the shares issued totaled $19.7 million, after payment of $0.3 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.

In November 2018, COPT replaced its 2016 ATM Program was registered with a new program under which itregistration statement. Under the 2022 ATM Program, we may offer and sell common shares in at-the-market stock offerings having an aggregate gross sales price of up to $300 million (the “2018 ATM Program”). Under the 2018 ATM Program, COPTand may also, at itsour discretion, sell common shares under forward equity sales agreements. As of December 31, 2019, COPT has2022, we had not issued any shares under the 20182022 ATM Program.

On November 2, 2017, COPT entered into forward equity sale agreements to issue 9.2 million common shares at an initial gross offering price of $285.2 million, or $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. COPT issued the following common shares under these forward equity sale agreements:

1.6 million shares in 2019 for net proceeds of $46.5 million;
5.9 million shares in 2018 for net proceeds of $172.5 million; and
1.7 million shares in 2017 for net proceeds of $50.0 million.

COPT contributed the net proceeds from these issuances to COPLP in exchange for an equal number of units in COPLP. COPT used its remaining capacity under these agreements in 2019.

Certain holders of COPLP common units converted their units into COPT common shares on the basis of 1one common share for each common unit in the amount of 105,0398,054 in 2019, 1.9 million2021 and 14,009 in 2018 and 339,5132020. No COPLP common units were converted in 2017.2022.

14.    Equity - COPLP and Subsidiaries

General Partner Preferred Units

In 2017, COPLP redeemed all of the outstanding units of the following series of preferred units held by COPT:

the 5.600% Series K Preferred Units effective on January 21, 2017; and
the 7.375% Series L Cumulative Preferred Units on June 27, 2017 at a price of $25.00 per unit, or $172.5 million in the aggregate, plus accrued and unpaid distributions thereon through the date of redemption, and recognized a $6.8 million decrease to net income available to common unitholders pertaining to the units’ original issuance costs at the time of redemption.

Following the completion of these redemptions in 2017, COPT held no preferred units in COPLP.

Limited Partner Preferred Units

COPLP has 352,000 Series I Preferred Units issued to an unrelated party that have an aggregate liquidation preference of $8.8 million ($25.00 per unit), plus any accrued and unpaid distributions of return thereon. The owner of these units is entitled to a priority annual cumulative return equal to 3.5% of their liquidation preference. These units are convertible into common units on the basis of 0.5 common units for each Series I Preferred Unit; the resulting common units would then be exchangeable for COPT common shares in accordance with the terms of COPLP’s agreement of limited partnership. These units may be redeemed for cash by COPLP at COPLP’s option on or after January 1, 2020, provided that COPLP provides notice to the unit holder six months prior to the effective date of the redemption.  The units’ terms also require COPLP to provide notice to the unit holder for defined periods of time in advance of the sale of certain property or repayment or refinancing of certain debt, after which, in certain instances, the unit holder would have the ability to require COPLP to redeem the units at their liquidation preference. The terms of these units were amended on July 31, 2019 to:

reduce, effective September 23, 2019, the priority annual cumulative return on these units from 7.5% of the units’ liquidation preference to 3.5%, and eliminate provisions for future increases previously in place;
extend the earliest date that COPLP could redeem the units to January 1, 2020; and
establish the notice provisions in advance of property sales and debt repayments or refinancing and related redemption requirements described above.

Common Units

COPT owned 98.7% of COPLP’s common units as of December 31, 2019 and 98.8% as of December 31, 2018.

In 2018 and 2017, COPT acquired additional common units through the following common share issuances under its 2016 ATM Program:

992,000 shares in 2018 at a weighted average price of $30.46 per share. Net proceeds from the shares issued totaled $29.8 million, after payment of $0.5 million in commissions to sales agents; and
591,000 shares in 2017 at a weighted average price of $33.84 per share. Net proceeds from the shares issued totaled $19.7 million, after payment of $0.3 million in commissions to sales agents.

From 2017 through 2019, COPT also acquired additional common units through the following common share issuances under its forward equity sale agreements:

1.6 million shares in 2019 for net proceeds of $46.5 million;
5.9 million shares in 2018 for net proceeds of $172.5 million; and
1.7 million shares in 2017 for net proceeds of $50.0 million.

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 1 common share for each common unit in the amount of 105,039 in 2019, 1.9 million in 2018 and 339,513 in 2017. 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 2019, 2018 and 2017.

15.    Share-Based Compensation and Other Compensation Matters
 
Share-Based Compensation Plans
 
In May 2017, COPTwe adopted the 2017 Omnibus Equity and Incentive Plan (the “2017 Plan”) following the approval of such plan by our common shareholders. COPTshareholders, and we amended the plan in November 2018 (as amended, the “2017 Plan”). We 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 of our 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, PIUs, 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.

In May 2010, COPT adopted the Amended and Restated 2008 Omnibus Equity and Incentive Plan following the approval of such plan by our common shareholders. This plan, which was replaced by Shares for the 2017 Plan providedare issued under a registration statement on Form S-8 that became effective upon filing with the Securities and Exchange Commission.

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 grants. We granted 2two 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

In 2019, our executives and certain non-employee Trustees were granted a total of 61,820 TB-PIUs with an aggregate grant date fair value of $1.6 million (weighted average of $26.01 per TB-PIU). TB-PIUs granted to executivessenior management team members vest in equal one-thirdbased on increments and over a three-year period beginning onperiods of time set forth under the dateterms of grant.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.

PB-PIUs

On January 1, 2019, we granted our executives 193,682The PB-PIUs witheach have a three-year performance period concluding on the earlier of December 31, 2021the respective performance period end dates, or the date of: (1) termination by us without cause, death or disability of the executiveemployee or constructive discharge of the executiveemployee (collectively, “qualified termination”); or (2) a sale event.  The number of earned awards at the end of the 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 RankEarned Awards Payout %
75th or greater100% of PB-PIUs granted
50th (target)50% of PB-PIUs granted
25th25% of PB-PIUs granted
Below 25th0% of PB-PIUs granted


If the percentile rank exceeds the 25th percentile and is between 2two 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 either:

for awards granted January 1, 2019 and 2020, 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. period; or
for awards granted January 1, 2021 and 2022, issuing additional vested PIUs equal to the excess, if any, of (1) 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 (2) the aggregate distributions made on the PB-PIUs during the performance period, divided by the price of our common shares on the settlement date.

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.

These PB-PIUs had an aggregate grant date fair value of $2.4 million ($12.47 per PB-PIU) which is being recognized over the performance period. The grant date fair value was computed using a Monte Carlo model that included the following assumptions: baseline common share value of $21.03; expected volatility for common shares of 21.0%; and a risk-free interest rate of 2.51%.  

PSUs

We made the following grants of PSUs to executives from 2015 through 2018 (dollars in thousands):
Grant Date Number of PSUs Granted Performance Period Commencement Date Performance Period End Date Grant Date Fair Value Number of PSUs Outstanding as of December 31, 2019
3/5/2015 45,656

1/1/2018 59,110
 1/1/2018 12/31/2020 $1,890
 59,110


In 2017, we also modified certain provisions of the PSUs granted in 2015, 2016 and 2017, resulting in incremental compensation cost totaling $236,000 based on the difference between the pre-modification and post-modification award fair values on the date of modification.

Notes to Consolidated Financial Statements (Continued)

The PSUs each have three-year performance periods concluding on the earlier of the respective performance period end dates set forth above or the date of: (1) termination by us without cause, death or disability of the executive or constructive discharge of the executive (collectively, “qualified termination”); or (2) a sale event.  The number of PSUs earned (“earned PSUs”) at the end of the performance period will be determined based on the percentile rank of COPT’s total shareholder return relative to a peer group of companies, as set forth in the following schedule:
Percentile RankEarned PSUs Payout %
75th or greater200% of PSUs granted
50th (target)100% of PSUs granted
25th50% of PSUs granted
Below 25th0% of PSUs granted


If the percentile rank exceeds the 25th percentile and is between 2 of the percentile ranks set forth in the table above, then the percentage of the earned PSUs will be interpolated between the ranges set forth in the table above to reflect any performance between the listed percentiles.  At the end of the performance period, we will settle the award by issuing fully-vested COPT shares 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 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 PSUs are forfeited.  PSUs do not carry voting rights.
Based on COPT’s total shareholder returnTSR relative to its peer group of companies:

for the 2015 PSUs2019 PB-PIUs issued to executivesemployees that vested on December 31, 2017,2021, we issued 13,328 common shares156,104 PIUs in settlement of the PSUsPB-PIUs on February 22, 2018;1, 2022; and

Deferred Share Awards

We made the following grants of deferred share awards to nonemployee members of our Board ofnon-employee Trustees in 2017, 20182020, 2021 and 20192022 (dollars in thousands, except per share data):

Deferred share awards vest on the first anniversary of the grant date, provided that the Trustee remains in his or her position. We settle deferred share awards by issuing an equivalent number of common shares upon vesting of the awards or a later date elected by the Trustee (generally upon cessation of being a Trustee). We did not have any award settlements in 2020, 2021 or 2022.

PSUs

As of December 31, 2022, we had no PSU grants outstanding. We last issued PSUs on January 1, 2018, when we granted executives 59,110 PSUs with a grant date fair value of $1.9 million and a three-year performance period.

The number of PSUs earned (“earned PSUs”) at the end of the performance period were determined based on the percentile rank of COPT’s TSR relative to a peer group of companies, as set forth in the following schedule:
Percentile RankEarned PSUs Payout %

At the end of the performance period, we settled the award by issuing fully-vested COPT shares equal to the number of earned PSUs in settlement of the award plan and paid 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. Based on COPT’s TSR relative to its peer group of companies, for the 2018 PSUs that vested on December 31, 2020, we issued 93,824 common shares in settlement of deferred shares in 2017, 2018 and 2019 (dollars in thousands, except per share data):the PSUs on February 3, 2021.

16.15.    Information by Business Segment

We have the following reportable segments: Defense/IT Locations; Regional Office; Wholesale Data Center;Center (the only property in which we sold on January 25, 2022); and Other. We also report on Defense/IT Locations sub-segments, which include the following: Fort George G. Meade and the Baltimore/Washington Corridor (referred to herein as “Fort(“Fort Meade/BW Corridor”); Northern VirginiaNoVA Defense/IT Locations;IT; Lackland Air Force Base (in San Antonio); locations serving the U.S. Navy (“Navy Support Locations”Support”), 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 generally fund the costs for the power, fiber connectivity and data center infrastructure). AsOur segment reporting included below reflects our retrospective reclassification of December 31, 2019, 2018 and 2017,two properties to our NoVA Defense/IT sub-segment from our Regional Office segment included properties located in select urban/urban-like submarkets in the Greater Washington, DC/Baltimore region with durable Class-A office fundamentals and characteristics; during 2017, this segment also included suburban properties not meeting these characteristics that were since disposed.first quarter of 2022.

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’sour ownership interest (“UJV NOI allocable to COPT”).

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):

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 2022.

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.

18.    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 awards using the if-converted or 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):

the numerator is adjusted to add back any changes in income or loss that would result from the assumed conversion into common units that we add to the denominator.

Summaries of the numerator and denominator for purposes of basic and diluted EPU calculations are set forth below (in thousands, except per unit data):

19.    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, 2019,2022, management believes that it is reasonably possible that we could recognize a loss of up to $3$4 million for certain municipal tax claims. Whileclaims; 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,federal, state and local environmental regulations related to our property ownership and operation.operations.  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 3three 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 muchmost 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 $34$29 million as of December 31, 2019.2022. 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, 2019,2022, we do not expect any such future fundings will be required.

Contractual Obligations

20.    Subsequent Event

On January 10, 2023, we sold a 90% interest in three data center shell properties in Northern Virginia based on an aggregate property value of $211.3 million and retained a 10% interest in the properties through Redshift JV LLC, a newly-formed joint venture. Our partner in the joint venture acquired the 90% interest from us for $190.2 million. We had amounts remaining to be incurred under various contractual obligations asrecognized a gain on sale of December 31, 2019 that includedapproximately $49 million. We are accounting for our interest in the following (excluding amounts incurred and therefore reflected as liabilities reported on our consolidated balance sheets):

development and redevelopment obligationsjoint venture using the equity method of $200.7 million;
tenant and other building improvements of $58.8 million;
third party construction obligations of $16.5 million; and
other obligations of $1.5 million.
