Letter to 
Shareholders

“Surround yourself with the best people you can find, 
delegate authority, and don’t interfere as long as the policy 
you’ve decided upon is being carried out.”

   —Ronald W. Reagan, 40th President of the United States

Our goals for 2015 were to improve portfolio occupancy, to refine 
our regional office portfolio strategy and to add value through 
low-risk development – all while remaining disciplined with our 
balance sheet. We are pleased to report success along all fronts.

Through leasing up existing vacancy and prudently investing, we 
improved core portfolio occupancy from 90.9% at the beginning 
of the year to 92.7% by year-end. Investment activity included 
opportunistically acquiring three Class-A office properties for 
$263.5 million. We purchased a 237,000 square foot building 
adjacent to the Dunn Loring-Merrifield Metro station for $80.5 
million that is 100% occupied by defense contractors serving the 
U.S. Government, thereby adding to our Defense / IT franchise. 
We also acquired two high rise buildings in the Pratt Street 
Corridor submarket of Baltimore’s Inner Harbor – a bold strategic 
move that, in conjunction with asset sales completed later in the 
year, enabled us to radically improve the composition and future 
growth profile of our regional office portfolio. Together, 250 West 
Pratt and 100 Light Streets contain 915,000 square feet that 
we acquired for $168 million1, or $184 per square foot. Due to 
our competitive advantage in underwriting each of these assets, 
we were able to purchase the properties at going-in cash yields 
that exceeded 8%. 

We sold $198.5 million of suburban office buildings and non-
strategic land to fund our acquisitions and improve our portfolio. 
By investing in the two Pratt Street submarket assets and selling 
suburban Baltimore assets, we increased the percentage of 
urban/urban-like assets in our regional office portfolio to 70%. 
Through additional asset sales we expect to accomplish in 2016, 
we will further refine our regional office portfolio’s composition to 
be more urban/urban like locations that will generate attractive 
same office cash NOI growth throughout the economic cycle.

From a valuation stand point, our capital recycling out of suburban 
properties and into urban, amenity and transportation-rich assets 
took many investors by surprise. This tactic prompted many 
outsiders to question how we were able to execute such a value 
trade. The answer is simple. As a local investor, we recognized the 
exogenous shift in demand to Baltimore’s waterfront from existing 
and new, high-quality tenants into this submarket ‒ a shift that 
national investors were not able to see as quickly. The exciting 
urban renaissance transforming Baltimore’s waterfront markets, 
combined with our attractive low basis in our buildings, creates 
the potential for long term value creation.

Development continues to be our primary growth engine, and 
in 2015 we advanced our reputation as the preeminent provider 
of real estate solutions for the U.S. Government and defense 
contractors. We completed 735,000 square feet of development 
leasing in 2015 (see chart below). When combined with 
development leasing achieved in 2012, 2013 and 2014, we have 
averaged roughly 1 million square feet of development leasing in 
each of the last four years. In 2015 we also placed 1.1 million 
square feet of newly developed buildings that were 97% leased 
into service. Of this total, seven projects totaling 897,000 square 
feet were leased to tenants at Defense / IT locations. As a result 
of our 2015 leasing and investment achievements, at year end, 
we derived 84% of our core portfolio’s annualized rental revenue 
from Defense / IT locations.

Rising demand from defense contractors at our Defense / IT 
locations underpins the strength of our leasing track record 
and our optimistic outlook for our development business. After 
four years of federal budget uncertainty that caused many 
contractors to reduce their square footage, defense spending 
– and contractor demand – are growing again. The Bipartisan 
Budget Act of 2015 provided two years of defense spending 
clarity and increases the base budget for the Department of 
Defense (“DOD”) through fiscal 2017. The Pentagon’s spending 
priorities emphasize high-tech missions and cybersecurity; our 
portfolio is geographically aligned with four of the country’s 
top five knowledge-based, high-tech defense installations. 
Accordingly, we expect growth in demand for new, efficient, 
precisely located development from the U.S. Government and 
defense contractors. 

In order to capture new development opportunities in our strategic 
markets, we need to maintain a strong, flexible balance sheet. In 
addition to selling nearly $200 million of non-strategic buildings and 
land last year, we resolved the Washington Tech Park CMBS loan, 
thereby eliminating $150 million of debt. We issued $300 million 
of 10-year, 5.0% senior notes and, in December, entered into a 
new 7-year, $250 million bank term loan with a fixed rate of 3.7% 
to pre-fund our 2016 debt maturities. As a result of these tactics, 
we re-fortified our balance sheet; our next balloon maturity does 
not occur until 2019 and our debt maturity ladder is 6.1 years.

Perhaps our greatest achievement in 2015 was executing on 
the Company’s leadership succession plans. Effective May 12, 
2016, Steve Budorick will assume the role of CEO. Since 2011, 
Steve has served as the company’s chief operating officer and 
has been the co-architect of the multi-level transformations 
the company has affected over the past four years. It is with 
complete confidence and sincere good wishes that I proudly 
pass the leadership baton to his capable hands. He is a proven 
leader and has the right vision to shepherd our company 
through its next era of growth.

Working over the past 30 years for a company that focuses 
on excellence and with such a talented team of people have 
been the highlights of my career. I thank you sincerely for your 
commitment to COPT,

Roger A. Waesche, Jr. 
President & Chief Executive Officer

Future Strategy  
Under New CEO

First, I want to thank Roger for his extraordinary 30-plus years of 
service to the company. I am honored to lead COPT into the next 
stage of investment and growth. Among the roughly two dozen 
office REITs, COPT will remain differentiated by its unique franchise 
of operating and developing specialized buildings that serve the 
U.S. Government and high-tech defense contractors, including 
defense information technology companies, cybersecurity firms 
and other contractors engaged in carrying out critical aspects 
of national security. Our customers rely on our office buildings 
to execute their missions in safe, efficient environments and 
in specific locations. Under my leadership, the Company will 
continue executing on our well-defined strategy to create lasting 
value for our customers, employees and shareholders, the main 
tactics of which are to maximize returns and cash flow from 
existing buildings, grow externally through low-risk development, 
primarily at our Defense / IT locations, and to continually improve 
our balance sheet flexibility and credit metrics. 

Thank you for your continued confidence in COPT,

Stephen E. Budorick

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

approximately $2.2 billion, as calculated using the closing price of such shares on the New York Stock Exchange and the number of outstanding shares as of June 
30, 2015.  For purposes of calculating this amount only, affiliates are defined as Trustees, executive owners and beneficial owners of more than 10% of Corporate 
Office Properties Trust’s outstanding common shares, $0.01 par value.  At February 16, 2016, 94,528,118 of  Corporate Office Properties Trust’s common shares 
were outstanding.  

The aggregate market value of the voting and nonvoting common units of limited partnership interest held by non-affiliates of Corporate Office Properties, 
L.P. was approximately $79.4 million, as calculated using the closing price of the common shares of Corporate Office Properties Trust (into which common units 
not held by Corporate Office Properties Trust are exchangeable) on the New York Stock Exchange and the number of outstanding units as of June 30, 2015.

Portions of the proxy statement of Corporate Office Properties Trust for its 2016 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, 2015 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, 2015, COPT owned 

approximately 96.3% of the outstanding common units and approximately 95.5% of the outstanding preferred units in COPLP.  The remaining 
common and preferred units in COPLP 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 Company and the 
Operating Partnership operate as an interrelated, consolidated company.  COPT is a real estate investment trust, 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 from time to time 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 through COPLP’s operations, by COPLP’s direct or indirect incurrence of indebtedness or 
through the issuance of partnership units.  

Noncontrolling interests and 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.  
COPLP’s consolidated financial statements also reflect COPT’s noncontrolling interests in certain real estate partnerships, limited liability 
companies (“LLCs”), business trusts and corporations; the differences between shareholders’ equity, partners’ capital and noncontrolling 
interests result from the differences in the equity issued at the COPT and COPLP levels and in COPT’s noncontrolling interests in these real 
estate partnerships, LLCs, business trusts and corporations.  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 (comprised primarily of mutual 
funds and equity securities) 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 and the analyst community view the business as a single operating unit; 
combined reports enhance investors’ understanding of the Company and the Operating Partnership by enabling them to view the business 
as a whole and in the same manner as management; 
combined reports are more efficient for the Company and the Operating Partnership and result in savings in time, effort and expense; and 
combined reports are more efficient for investors by reducing duplicative disclosure and providing a single document for their review. 

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

• 
• 

• 

• 

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 13, Equity of COPT and subsidiaries;
•  Note 14, Equity of COPLP and subsidiaries;
•  Note 19, Earnings per Share of COPT and subsidiaries and Earnings per Unit of COPLP and subsidiaries; and
•  Note 22, 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.

FORWARD-LOOKING STATEMENTS

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

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

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

• 

• 
• 

• 
• 

• 

• 

• 

• 
• 
• 

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

We undertake no obligation to publicly update or supplement forward-looking statements, whether as a result of new 
information, future events or otherwise.  For further information on these and other factors that could affect us and the 
statements contained herein, you should refer to the section below entitled “Item 1A. Risk Factors.”

Item 1. Business

OUR COMPANY

PART I

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

and self-managed real estate investment trust (“REIT”).  Corporate Office Properties, L.P. (“COPLP”) and subsidiaries 
(collectively, the “Operating Partnership”) is the entity through which COPT, the sole general partner of COPLP, conducts 
almost all of its operations and owns almost all of its assets.  Unless otherwise expressly stated or the context otherwise 
requires, “we”, “us” and “our” as used herein refer to each of the Company and the Operating Partnership.  We own, manage, 
lease, develop and selectively acquire office and data center properties.  The majority of our portfolio is in locations that 
support United States Government agencies and their 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 complementary portfolio of traditional office properties located in select urban/urban-like 
submarkets within our regional footprint with durable Class-A office fundamentals and characteristics, as well as other 
properties supporting general commercial office tenants (“Regional Office”).  As of December 31, 2015, our properties 
included the following:

• 

• 

• 
• 

177 operating office properties totaling 18.1 million square feet that were 92% occupied, including nine triple-net leased, 
single-tenant data center properties;
13 office properties under, or contractually committed for, construction or redevelopment that we estimate will total 
approximately 1.5 million square feet upon completion, including one partially operational property included above;
1,439 acres of land we control that we believe are potentially developable into approximately 17.6 million square feet; and
a wholesale data center with a critical load of 19.25 megawatts.

COPLP owns real estate both 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 
and construction and development 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, 2015, COPT owned 96.3% 

of the outstanding COPLP common units (“common units”) and 95.5% of the outstanding COPLP preferred units (“preferred 
units”); the remaining common and preferred units in COPLP were owned by third parties.  Common units in COPLP not 
owned by COPT carry certain redemption rights.  The number of common units in COPLP owned by COPT is equivalent to the 
number of outstanding common shares of beneficial interest (“common shares”) of COPT, and the entitlement of all COPLP 
common units to quarterly distributions and payments in liquidation is substantially the same as those of COPT common 
shareholders.  Similarly, in the case of each series of preferred units in COPLP held by COPT, there is 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, and although, as a partnership, COPLP does not have a board of 
trustees, we refer to COPT’s Board of Trustees as COPLP’s Board of Trustees.

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

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

telephone number is (443) 285-5400.  

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

6

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

The SEC maintains an Internet website that contains reports, proxy and information statements and other information 
regarding issuers that file electronically with the SEC.  This Internet website can be accessed at www.sec.gov.  The public may 
also read and copy paper filings that we have made with the SEC at the SEC’s Public Reference Room, located at 100 F Street, 
NE, Washington, DC 20549.  Information on the operation of the Public Reference Room may be obtained by calling (800) 
SEC-0330.

Significant Developments

250 W. Pratt Street, a 367,000 square foot property in Baltimore, Maryland that was 96.2% leased, for $61.8 million 
on March 19, 2015; 
2600 Park Tower Drive, a 237,000 square foot property in Northern Virginia that was 100% leased, for $80.5 million 
on April 15, 2015; and
100 Light Street, a 558,000 square foot office property in Baltimore, Maryland that was 93.5% leased, and its 
structured parking garage, 30 Light Street, for $121.2 million on August 7, 2015.  In connection with that acquisition, 
we assumed a $55.0 million mortgage loan;

• 

disposed of nine office properties totaling 1.6 million square feet and land for transaction values totaling $365.9 million, 
including:

seven office properties (five in Baltimore County, Maryland and two in Northern Virginia) and land sold for $198.5 
million; and
two office properties in Northern Virgina totaling 665,000 square feet that secured a $150.0 million nonrecourse 
mortgage loan.  On August 28, 2015, ownership in these properties was transferred to the mortgage lender and we 
removed the debt obligation and accrued interest from our balance sheet;

• 

• 

• 

issued $300.0 million of 5.00% Senior Notes on June 29, 2015 at an initial offering price of 99.51% of their face value.  
The proceeds from the issuance, after deducting underwriting discounts but before other offering expenses, were 
approximately $296.6 million;
entered into an unsecured term loan agreement on December 17, 2015 with an initial commitment of $250.0 million of 
which we borrowed $100.0 million; and
issued 890,241 COPT common shares at a weighted average price of $30.29 per share under our at-the-market stock 
offering program established in October 2012.  Net proceeds from the shares issued totaled $26.6 million.  The net 
proceeds were contributed to COPLP in exchange for 890,241 common units. 

On February 10, 2016, our Board of Trustees appointed Stephen E. Budorick, our Executive Vice President and Chief 
Operating Officer since September 2011, to become our President and Chief Executive Officer effective May 12, 2016, the date 
of the Company’s 2016 Annual Meeting of Shareholders.  On that date, Roger A. Waesche, Jr., our current President and Chief 
Executive Officer, will leave the Company to pursue other interests and he will not be nominated for reelection as a Trustee.  
The Board expects to appoint Mr. Budorick to our Board of Trustees after the 2016 Annual Meeting of 

Business and Growth Strategies

Our primary goal is to 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 of our Defense/IT Locations.  
The majority of our properties are located adjacent to, or houses, United States Government agencies.  Our customers in these 
properties are primarily United States Government agencies and their contractors engaged in activities servicing what we 
believe are high priority security, defense and IT missions.  These tenants’ missions generally pertain to knowledge-based 

7

activities (such as cyber security, research and development and other highly technical defense and security areas) rather than to 
force structure (troops) and weapon system production.  A high percentage of our revenue (80.8% as of December 31, 2015) is 
concentrated in Defense/IT Locations, and we expect to maintain a high concentration through our:

• 

• 

• 

properties’ (existing buildings and developable land we control) proximity to defense installations and other knowledge-
based government demand drivers, and our willingness to expand to new locations with similar proximities;
extensive experience in developing secured, specialized space, with the ability to satisfy the United States Government’s 
unique needs, including Sensitive Compartmented Information Facility (“SCIF”) and Anti-Terrorism Force Protection 
(“ATFP”) requirements;
depth of knowledge, specialized skills and credentialed personnel in operating highly specialized space with security-
oriented needs;

•  well-established relationships with United States Government agencies and their contractors; and
• 

track record of providing service that exceeds customer expectations both in terms of the quality of the space we provide 
and our level of responsiveness to their needs.  We believe that operating with such an emphasis on service enables us to be 
a landlord of choice with high quality tenants of these properties and contributes to high levels of customer loyalty and 
retention.

Regional Office Strategy: While our primary focus pertains to Defense/IT Locations, we also own a portfolio of traditional 

office properties located in select urban/urban-like submarkets within our regional footprint with durable Class-A office 
fundamentals and characteristics, as well as other properties supporting general commercial office tenants.  We believe that our 
Regional Office portfolio enables us to leverage our local expertise in a region into a second growth platform in a way that is 
complementary to our Defense/IT Locations strategy.  Characteristics that we seek in Regional Office submarkets include: (1) 
mixed-use, lifestyle oriented locations with a robust high-end residential and retail base; (2) proximity to public transportation 
and major transportation routes; (3) educated workforce; and (4) diverse and growing employment base.  We believe that these 
types of submarkets provide better overall quality and opportunity for long-term, sustained growth than other commercial office 
submarkets.

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) achievement of operating efficiencies by increasing 
economies of scale and, where possible, aggregating vendor contracts to achieve volume pricing discounts; (3) renewing tenant 
leases and re-tenanting at increased rents where market conditions permit; and (4) redevelopment when we believe property 
conditions and market demand warrant.  We may also seek to dispose of properties when they 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 and be better positioned for long-term growth.  

We also aim to develop and operate our properties in a manner that minimizes adverse impact on the environment by: (1) 
constructing new buildings designed to use resources with a high level of efficiency and low impact on human health and the 
environment during their life cycles through our participation in the U.S. Green Building Council’s Leadership in Energy and 
Environmental Design (“LEED”) program; (2) investing in energy systems and other equipment that reduce energy 
consumption and property operating costs; and (3) adopting select LEED Existing Building (“EB”) prerequisites for much of 
our portfolio, including guidelines pertaining to cleaning and recycling practices and energy reduction.  In 2015, we 
participated for the first time in the GRESB (or Global Real Estate Sustainability Benchmark) survey, which is widely 
recognized for measuring the sustainability performance of real estate companies and funds, and earned an overall score of 
“Green Star,” which represents the highest quadrant of achievement from the survey.

Property Development and Acquisition Strategy: We pursue property development and acquisition opportunities for 
properties that fit our Defense/IT Locations and Regional Office strategies and, as discussed above, have significant land 
holdings that we believe can help fuel future development of Defense/IT Locations in particular.  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 construction.  We typically seek to make acquisitions 
at attractive yields and below replacement cost, or that otherwise meet our strategic objectives.  We also seek to increase 
operating cash flow of certain acquisitions by repositioning the properties and capitalizing on existing below market leases and 
expansion opportunities.  

Capital Strategy: Our capital strategy is aimed at maintaining access to capital in the face 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;

8

using secured nonrecourse debt from institutional lenders and banks;

• 
•  managing our debt by monitoring, among other things: (1) our total and secured debt levels relative to our overall capital 

structure; (2) the relationship of certain measures of earnings to our debt level and to certain capital costs; (3) the timing of 
debt maturities to ensure that maturities in any year do not exceed levels that we believe we can refinance; and (4) the 
relationship of our variable-rate debt to our total debt;
using equity raised through issuances of common and preferred shares, issuances of common and preferred units in COPLP 
and, to a lesser extent, joint venture structures for certain investments;
paying dividends at a level that at least enables us to maintain our REIT status;
recycling proceeds from property sales under our asset management strategy (discussed above) to fund our investment 
activities and to reduce overall debt; and
continuously evaluating the ability of our capital resources to accommodate our plans for future growth.

Industry Segments

We operate in two primary industries: commercial office properties and our wholesale data center.  Effective in the quarter 

ended December 31, 2015, we changed the reportable segments that we use to review operating results and make decisions 
regarding segment performance and resource allocation.  Given the changes in our portfolio resulting from development, 
acquisition and disposition activities, we made this change to better align our segments with our business strategy by 
contemplating the market characteristics of our properties.  As of December 31, 2015, our commercial office real estate 
operations included the following: Defense/IT Locations and Regional Office.  Our segment reporting also included reporting 
for Defense/IT Locations sub-segments, which included the following: 

Fort George G. Meade and the Baltimore/Washington Corridor (referred to herein as “Fort Meade/BW Corridor”);

• 
•  Northern Virginia Defense I/T Locations;
•  Lackland Air Force Base in San Antonio, Texas;
• 

locations serving the U.S. Navy (referred to herein as “Navy Support Locations”).  Properties in this segment as of 
December 31, 2015 were 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, Alabama; and
• 

data center shells, which are 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.  Most of our data center shells as of December 31, 
2015 were proximate to the MAE-East Corridor, a major center in the United States for interconnecting traffic between 
Internet service providers.

As of December 31, 2015, Defense/IT Locations comprised 146 of our office properties, or 79.6% of our square feet in 
operations, while Regional Office comprised 24 of our office properties, or 17.7% of our square feet in operations.  Our 
wholesale data center, which is comprised of one property in Manassas, Virginia, is reported as a separate segment.  

For information relating to our segments, you should refer to Note 17 to our consolidated financial statements, which is 

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

Employees

As of December 31, 2015, we had 383 employees, none of whom were parties to collective bargaining agreements.  We 

believe that our relations with our employees are good.

Competition

The commercial real estate market is highly competitive.  Numerous commercial properties 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 than we are.  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 
meeting our short-term capital needs. 

We compete for the acquisition of 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.  If our 

9

competitors prevent us from buying properties that we have targeted for acquisition, we may not be able to meet our property 
acquisition goals. 

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

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

Item 1A.  Risk Factors

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

uncertainties may lead to outcomes that could adversely affect our financial position, results of operations, cash flows and 
ability to make expected distributions to our equityholders.  You should carefully consider each of these risks and uncertainties 
and 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, 2015, which are included in a separate section at the end of this report 
beginning on page F-1.

Our performance and 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 economic performance and the value of our real estate assets may decline due to conditions in the general 
economy and the real estate business which, in turn, could have an adverse effect on our financial position, results of 
operations, cash flows and ability to make expected distributions to our shareholders.  These conditions include, but are not 
limited to:

• 

• 
• 
• 
• 
• 
• 
• 

• 

• 
• 

• 
• 
• 
• 

downturns in national, regional and local economic environments, including increases in the unemployment rate and 
inflation or deflation;
competition from other properties;
deteriorating local real estate market conditions, such as oversupply, reduction in demand and decreasing rental rates;
unavailability of financing for potential purchasers of our properties;
declining real estate valuations;
increasing vacancies and the need to periodically repair, renovate and re-lease space;
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 a curtailment of 
demand for additional space by our strategic customers;
increasing operating costs, including insurance expenses, utilities, real estate taxes and other expenses, much of which we 
may not be able to pass through to tenants;
increasing interest rates and unavailability of financing on acceptable terms or at all;
trends in office real estate that may adversely affect future demand, including telecommuting and flexible workplaces that 
increase the population density per square foot; 
adverse changes in taxation or zoning laws;
potential inability to secure adequate insurance;
adverse consequences resulting from civil disturbances, natural disasters, terrorist acts or acts of war; and
potential liability under environmental or other laws or regulations.

We may suffer adverse consequences as a result of adverse economic conditions.  Our business may be affected by 

adverse economic conditions in the United States economy or real estate industry as a whole or by the local economic 
conditions in the markets in which our properties are located, including the impact of high unemployment and constrained 
credit.  Adverse economic conditions could increase the likelihood of tenants encountering financial difficulties, including 
bankruptcy, insolvency or general downturn of business, and as a result could increase the likelihood of tenants defaulting on 
their lease obligations to us.  Such conditions also could increase the likelihood of our being unsuccessful in renewing tenants, 
renewing tenants on terms less favorable to us or being unable to lease newly constructed properties.  In addition, such 
conditions could increase the level of risk that we may not be able to obtain new financing for development activities, 
acquisitions, refinancing of existing debt 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 renting our properties.  Our operating costs do not necessarily fluctuate in relation to changes in our rental revenue.  This 
means that our costs will not necessarily decline and may increase even if our revenues decline.  

10

For new tenants or upon lease expiration for existing tenants, 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 have 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, government shutdown, or general downturn of business. 

We may be adversely affected by developments concerning some of our major tenants and sector concentrations, 
including prolonged shutdowns of the United States Government and actual, or potential, reductions in government 
spending targeting United States Government agencies and defense contractors engaged in knowledge-based activities.   
As of December 31, 2015, our 20 largest tenants accounted for 63.8% of the total annualized rental revenue of our office 
properties, and the four largest of these tenants accounted for 41.9%.  We calculated the annualized rental revenue by 
multiplying by 12 the sum of monthly contractual base rents and estimated monthly expense reimbursements under active 
leases in our portfolio of office properties as of December 31, 2015.  Information regarding our four largest tenants is set forth 
below:

Most of our leases with the United States Government provide for a series of one-year terms or provide for early 

termination rights.  The United States Government 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, including as 
a result of a prolonged government shutdown, or if the United States Government elects to terminate some or all of its leases 
and the space cannot be re-leased on satisfactory terms. 

As of December 31, 2015, 80.8% of the total annualized rental revenue of our office properties was from Defense/IT 
Locations, and we expect to maintain a similarly high revenue concentration in these types of properties.  A reduction in 
government spending targeting the activities of these agencies and contractors (such as knowledge-based defense and security 
activities) could affect the ability of these tenants to fulfill lease obligations, decrease the likelihood that these tenants will 
renew their leases or enter into new leases and limit our future growth from these sectors.  Moreover, uncertainty regarding the 
potential for future reduction in government spending targeting such activities could also decrease or delay leasing activity 
from tenants engaged in these activities.

Most of our properties are geographically concentrated in the Mid-Atlantic region, particularly in the Greater 
Washington, DC/Baltimore region, or in particular office parks.  We may suffer economic harm in the event of a decline 
in the real estate market or general economic conditions in those regions or parks.  Most of our properties are located in 
the Mid-Atlantic region of the United States, particularly in the Greater Washington, DC/Baltimore region.  Our properties are 
also often concentrated in office parks in which we own most of the properties.  Consequently, our portfolio of properties is not 

11

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 office 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.  Some businesses increasingly permit 
employee telecommuting, flexible work schedules, open workplaces and teleconferencing.  These practices enable businesses 
to reduce their space requirements.  These trends could over time erode the overall demand for office space and, in turn, place 
downward pressure on occupancy, rental rates and property valuations.

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

We may not be able to compete successfully with other entities that operate in our industry.  The commercial real 
estate market is highly competitive.  We compete for the purchase of commercial property with many entities, including other 
publicly traded commercial REITs.  Many of our competitors have substantially greater financial resources than we do.  If our 
competitors prevent us from buying properties that we target for acquisition, we may not be able to meet our property 
acquisition goals.  Moreover, 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. 

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.  We intend to sell properties to fund our development plans and reduce debt.  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 quickly change our portfolio of properties in response 
to changes in economic or other conditions.  Our failure to successfully execute dispositions could adversely affect our ability 
to effectively execute our business strategy.  Moreover, under certain circumstances, the Internal Revenue Code imposes certain 
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.  In addition, for certain of our properties that we acquired by issuing units in COPLP, we are restricted by agreements with 
the sellers of the properties for a certain period of time from entering into transactions (such as the sale or refinancing of the 
acquired property) that will result in a taxable gain to the sellers without the seller’s consent.

We are dependent on external sources of capital for future 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 
acquisition, construction and development activities using retained cash flow from operations.  Therefore, our ability to fund 
these activities is dependent on our ability to access debt or equity capital.  Such capital could be in the form of new debt, 
common shares, preferred shares, common and preferred units in COPLP or joint venture funding.  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, and additional equity offerings may 
result in substantial dilution of our equityholders’ interests.  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.  We also use other credit facilities to fund a significant portion of our construction activities.  Our lenders under these 
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 plans to acquire existing commercial real estate properties.  We may 
acquire existing commercial real estate properties to the extent that suitable acquisitions can be made on advantageous terms. 
12

Acquisitions of commercial properties entail risks, such as the risks 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 will fail to perform as 
expected.

We may be exposed to unknown liabilities from acquired properties.  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, which could adversely affect our results of operations and cash flow.  
Examples of unknown liabilities with respect to acquired properties include, but are not limited to: 

• 
• 
• 
• 

liabilities for clean-up 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.

We may suffer economic harm as a result of making unsuccessful acquisitions in new markets.  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 in other acquisitions where we are familiar with the regions, such as the risk that we do not 
correctly anticipate conditions or trends in a new market and are therefore not able to operate the acquired property profitably.

We may be unable to execute our plans to develop and construct additional properties.  Although the majority of our 
investments are in currently leased properties, we also develop, construct and redevelop properties, including some that are not 
fully pre-leased.  When we develop, construct and redevelop properties, we assume the risk that actual costs will exceed our 
budgets, that we will experience conditions which delay or preclude project completion and that projected leasing will not 
occur.  In addition, we generally do not obtain construction financing commitments until the development stage of a project is 
complete and construction is about to commence.  We may find that we are unable to obtain financing needed to continue with 
the construction activities for such projects.

Our data centers may become obsolete.  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 data centers are rapidly evolving and, as a result, the risk of investments we make in 
data centers becoming obsolete is higher than office properties.  Our data centers 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.  

Certain of our properties containing data centers contain space not suitable for lease other than as data centers, 
which could make it difficult to reposition them for alternative use.  Certain of our properties contain data center space, 
which is highly specialized space containing extensive electrical and mechanical systems that are designed uniquely to run and 
maintain banks of computer servers.  As discussed above, our 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.

We may suffer adverse effects as a result of the indebtedness that we carry and the terms and covenants that relate 

to this debt.  Some of our properties are pledged by us to support repayment of indebtedness.  Any foreclosure on our 
properties could result in loss of income and asset value.  In addition, we rely on borrowings to fund some or all of the costs of 
construction and development activities, new property acquisitions and other items.  Our organizational documents do not limit 
the amount of indebtedness that we may incur.  

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 its 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

13

• 

if we are unable to pay our debt service on time or are unable to comply with restrictive financial covenants in 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, 2015, our scheduled debt maturities over the next five years were as follows:

$43.5 million in 2019 that may be extended to 2020, subject to certain conditions.

Our operations likely will not generate enough cash flow to repay some or all of this debt without additional borrowings, equity 
issuances and/or property sales.  If we cannot refinance our debt, extend the repayment dates, or raise additional equity prior to 
the dates when our debt matures, we would default on our existing debt. 

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 in terms of ratings or outlook by the credit 
rating agencies would have a material adverse impact on our cost and availability of capital and also have a material adverse 
effect on the market price of COPT’s common shares. 

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 acquisitions and development activity.  Also, it is possible that because of the 
differences between the time we actually receive revenue or pay expenses and the period during which we report those items 
for distribution purposes, we may have to borrow funds for COPT to meet the 90% distribution requirement.  

We may be unable to continue to make equityholders distributions 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.  Our ability to make distributions at expected levels will also be dependent, in part, on 
other matters, including, but not limited to: 

• 
• 
• 
• 
• 
• 

• 
• 
• 
• 

continued property occupancy and timely receipt of rent obligations; 
the amount of future capital expenditures and expenses relating to our properties; 
the level of 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 our preferred shares/units. 

14

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 in the future be issued 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 incur additional indebtedness, which may harm our financial position and cash flow and potentially impact 

our ability to pay distributions to equityholders.  Our governing documents do not limit us from incurring additional 
indebtedness and other liabilities.  As of December 31, 2015, we had $2.1 billion of indebtedness outstanding.  We may incur 
additional indebtedness and become more highly leveraged, which could harm our financial position. 

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, for example, as to whether 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.

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

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

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.

15

 
Terrorist attacks 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 and near military installations.  Future terrorist attacks 
could directly or indirectly damage our properties or cause losses that materially exceed our insurance coverage.  After such an 
attack, 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, and fewer customers may choose to patronize businesses in these areas.  This in 
turn would trigger a decrease in the demand for space in these areas, which could increase vacancies in our properties and force 
us to lease space on less favorable terms. 

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

We may be subject to increased costs of insurance and limitations on coverage, particularly regarding acts of 
terrorism.  Our portfolio of properties is insured for losses under our property, casualty and umbrella insurance policies 
through September 30, 2016.  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. 

Our business could be adversely affected by a negative audit by the United States Government.  Agencies of the 

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

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 United States Government 
agencies and their contractors with a general focus on national security and information technology, we may be especially 
likely to be targeted by cyber attacks, including by governments, organizations or persons hostile to our government.  Despite 
our activities to maintain the security and integrity of our networks and related systems, as well as purchasing available 
insurance coverage, 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 by 
creating difficulties for our tenants that may reflect poorly on us.

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

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

COPT’s Declaration of Trust includes other provisions that may prevent or delay a change of control.  Subject to the 
requirements of the New York Stock Exchange, our Board of Trustees has the authority, without shareholder approval, to issue 
additional securities on terms that could delay or prevent a change in control.  In addition, our Board of Trustees has the 

16

authority to reclassify any of our unissued common shares into preferred shares.  Our Board of Trustees may issue preferred 
shares with such preferences, rights, powers and restrictions as our Board of Trustees may determine, which could also delay or 
prevent a change in control. 

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

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

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

We could face possible adverse changes in tax laws, which may result in an increase in our tax liability.  From time to 
time, changes in state and local tax laws or regulations are enacted that may result in an increase in our tax liability.  The shortfall 
in tax revenues for states and municipalities in recent years 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 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 COPT’s common and preferred shares.  These conditions 
include, but are not limited to: 

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

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

adverse changes in tax laws. 

We may 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 any of these financial institutions files for bankruptcy 
protection.

(1)  This percentage is based upon all rentable square feet under lease terms that were in effect as of December 31, 2015. 
(2)   Annualized rental revenue is the monthly contractual base rent as of December 31, 2015 (ignoring free rent then in effect) multiplied by 

12, plus the estimated annualized expense reimbursements under existing leases.  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, segment and industry 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, 2015.  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 $29.37 for our total office portfolio, $31.26 for Fort Meade/
BW Corridor (our largest Defense/IT Location subsector) and $28.29 for our Regional Office portfolio.

(4)   Includes 13 properties classified as held for sale as of December 31, 2015.

With regard to leases expiring in 2016, we believe that the weighted average annualized rental revenue per occupied square 
foot for such leases as of December 31, 2015 was, on average, approximately 2% to 3% higher than estimated current market 
rents for the related space, with specific results varying by market.

The following table provides a summary schedule of the lease expirations for leases in place at our wholesale data center 

property as of December 31, 2015 (dollars and square feet in thousands):

(1)  The leasing statistics set forth above assume no exercise of any existing early termination rights.  Most of the leases with our largest tenant, the United States 
Government, provide for consecutive one-year terms; all of the leasing statistics set forth above assume that the United States Government will remain in the 
space that they lease through the end of the respective arrangements, without ending consecutive one-year leases prematurely. 

(2)  Annualized rental revenue is the monthly contractual base rent as of December 31, 2015 multiplied by 12, plus the estimated annualized expense 

reimbursements under existing office leases.  Our computation of annualized rental revenue excludes the effect of lease incentives, although the effect of this 
exclusion is generally not material.

Item 3.  Legal Proceedings

We are not currently involved in any material litigation nor, to our knowledge, is any material litigation currently 
threatened against the Company or the Operating Partnership (other than routine litigation arising in the ordinary course of 
business, substantially all of which is expected to be covered by liability insurance).

Item 4.  Mine Safety Disclosures

Not applicable.

The number of holders of record of COPT’s common shares was 489 as of December 31, 2015.  This number does not 

include shareholders whose shares are held of record by a brokerage house or clearing agency, but does include any such 
brokerage house or clearing agency as one record holder. 

COPT pays dividends at the discretion of its Board of Trustees.  COPT’s ability to pay cash dividends will be dependent 
upon: (1) the cash flow generated from our operations; (2) cash generated or used by our financing and investing activities; and 
(3) the annual distribution requirements under the REIT provisions of the Code described above and such other factors as the 
Board of Trustees deems relevant.  COPT’s ability to make cash dividends will also be limited by the terms of COPLP’s 
Partnership Agreement, as well as by limitations imposed by state law.  In addition, COPT is prohibited from paying cash 
dividends in excess of the amount necessary for it to qualify for taxation as a REIT if a default or event of default exists 
pursuant to the terms of our Revolving Credit Facility; this restriction does not currently limit COPT’s ability to pay dividends, 
and COPT does not believe that this restriction is reasonably likely to limit its ability to pay future dividends because it expects 
to comply with the terms of our Revolving Credit Facility.

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

were the same as quarterly common dividends per share declared by COPT.  As of December 31, 2015, there were 36 holders 
of record of COPLP’s common units.

(1)  Certain prior period amounts pertaining to properties included in discontinued operations have been reclassified to conform with 

the current presentation. These reclassifications did not affect consolidated net income or shareholders’ equity. 

(2)  Includes income derived from 23 operating properties disposed in 2011, 35 operating properties disposed in 2012 and 31 operating 

properties disposed in 2013 (see Note 18 to our consolidated financial statements). 

(3)  Reflects gain from sales of properties and unconsolidated real estate joint ventures not associated with discontinued operations. 

(4)  Reflects a decrease to net income available to common shareholders pertaining to the original issuance costs recognized upon the 
redemption of the Series G Preferred Shares in 2012, Series J Preferred Shares in 2013 and Series H Preferred Shares in 2014. 

(5)  Basic and diluted earnings per common share are calculated based on amounts attributable to common shareholders of COPT.

(6)  Prior period amounts include retrospective adjustments to reclassify net deferred financing costs in connection with recent 

accounting guidance adopted in 2015.

(7)  For definitions of diluted funds from operations per share and diluted funds from operations and reconciliations of these measures 
to their comparable measures under generally accepted accounting principles, you should refer to the section entitled “Funds from 
Operations” within the section entitled “Management's Discussion and Analysis of Financial Condition and Results of Operations.” 

(8)  Amounts reported reflect only operating office properties.

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

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

you read this section.

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

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

• 

• 
• 

• 
• 

• 

• 

• 

• 
• 
• 

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

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

Overview

Our revenues relating to real estate operations are derived from rents and property operating expense reimbursements 
earned from tenants leasing space in 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.  Most of our profitability from real estate operations depends on our ability to 
maintain high levels of occupancy and increase rents, which is affected by a number of factors, including, among other things, 
our tenants’ ability to fulfill their lease obligations and their continuing space needs based on variables such as employment 
levels, business confidence, competition, general economic conditions of the markets in which we operate and governmental 
actions and initiatives.

Due to our Defense/IT Locations strategy, a large concentration of our revenue is derived from several large tenants.  As of 
December 31, 2015, 63.8% of our annualized rental revenue (as defined below) from office properties was from our 20 largest 
tenants, 41.9% from our four largest tenants and 29.0% from our largest tenant, the United States Government.  In addition, 
80.8% of the total annualized rental revenue of our office properties was from Defense/IT Locations properties.

In 2015, we believe that we improved both the strategic focus and quality of our property portfolio through development, 

acquisition and disposition activities.  For our Defense/IT Locations, we

• 

placed into service an aggregate of 897,000 square feet in seven newly constructed properties that were 100.0% leased as 
of December 31, 2015, including three data center shells totaling 421,000 square feet; and

28

 
• 

acquired 2600 Park Tower Drive, a 237,000 square foot property in a transportation-served, urban-like submarket of 
Northern Virginia that was 100% leased, for $80.5 million on April 15, 2015 primarily using borrowings from our 
Revolving Credit Facility.

For our Regional Office portfolio, we:

• 

 acquired the following properties in the heart of Baltimore City’s central business district:

250 W. Pratt Street, a 367,000 square foot property that was 96.2% leased, for $61.8 million on March 19, 2015 
primarily using borrowings from our Revolving Credit Facility; and
100 Light Street, a 558,000 square foot office property in Baltimore, Maryland that was 93.5% leased, and its 
structured parking garage, 30 Light Street, for $121.2 million on August 7, 2015.  In connection with that acquisition, 
we assumed a $55.0 million mortgage loan, and funded the balance primarily using borrowings from our Revolving 
Credit Facility; and

• 

sold seven suburban office properties (five in Baltimore County, Maryland and two in Northern Virginia) totaling 932,000 
square feet that were 100% leased upon disposition and land for $198.5 million.  The office properties were not located in 
transportation-served, urban or urban-like locations, and therefore were not deemed to be as strategic as the properties we 
acquired.  While most of the proceeds from these sales were used to repay borrowings under our Revolving Credit Facilty 
and for general corporate purposes, we also held $57.2 million in cash from these sales as of December 31, 2015 that we 
expect to use in 2016 to fund development activities.  

Our capital activities in 2015 focused on funding our development and acquisition activities and extending our debt 

maturities by:

• 
• 

• 

• 

• 

completing the property sales discussed above; 
issuing $300.0 million of 5.000% Senior Notes, which are unsecured and guaranteed by COPT, on June 29, 2015 at an 
initial offering price of 99.510% of their face value.  The proceeds from the offering, after deducting underwriting 
discounts but before other offering expenses, were approximately $296.6 million.  We used the net proceeds of the offering 
to repay borrowings under our Revolving Credit Facility; 
entering into an unsecured term loan agreement with an initial commitment of $250.0 million, of which we borrowed 
$100.0 million.  We used the proceeds to repay term loan debt previously scheduled to mature in 2016.  We have until 
September 2016 to draw the remaining $150.0 million of the initial commitment, which we expect to use to repay most of 
our debt maturing in 2016; 
disposing of two office properties in Northern Virgina totaling 665,000 square feet that secured a $150.0 million 
nonrecourse mortgage loan.  On August 28, 2015, ownership in these properties was transferred to the mortgage lender and 
we removed the debt obligation and accrued interest from our balance sheet; and
issuing 890,241 COPT common shares at a weighted average price of $30.29 per share under its at-the-market stock 
offering program established in October 2012.  Net proceeds from the shares issued totaled $26.6 million.  The net 
proceeds from the shares issued were contributed to COPLP in exchange for 890,241 common units, and used by COPLP 
for general corporate purposes.

Our outstanding debt increased in 2015 from year-end 2014 due to the funding requirements of our development and 
acquisition activities exceeding the effects of the above capital activities.  We improved the timing of our debt maturities in 
2015 by ending the year with a weighted average debt maturity of 6.1 years, a one-year increase over year-end 2014, and 
minimal cash or new financing required for scheduled debt maturities through 2018.  In addition, the fixed-rate portion of our 
debt was 90.5% by year-end 2015 (including the effect of variable rate loans subject to interest rate), virtually unchanged from 
year end 2014.

In the second half of 2015, we determined that we were unwilling to issue common shares at current pricing levels to 
reduce debt and fund development costs.  We concluded instead that sales of selected operating properties and land were our 
best source of capital.  In the preparation of our business plan, we determined that we expect to sell at least $400 million of 
operating properties and $40 million of land in 2016.  In the fourth quarter of 2015, we identified some of these properties that 
we will attempt to sell, including some land parcels.  We also determined that we will not likely develop additional properties 
on land parcels not proximate to our Defense/IT Locations.  As a result of those decisions, we recognized approximately $20 
million of impairment losses in the fourth quarter of 2015.  As we identify additional properties for sale, we may recognize 
additional impairment losses.

For an extended number of years, our ability to lease Defense/IT Locations was adversely effected by continuing delays in 

Federal budget approvals and uncertainty regarding the potential for future reductions in government spending targeting 
defense.  This served to disrupt the Government’s process for awarding contracts to prospective tenants, causing significant 

29

contraction in the defense contractor sector.  In January 2014, the 2014 Consolidated Appropriations Act (the “2014 Act”) was 
passed, establishing a budget for the 2014 fiscal year that rolled back certain of the defense spending reductions that were to 
occur under the Budget Control Act of 2011.  With the passage of the 2014 Act, defense spending levels were essentially flat in 
2014 through September 30, 2015.  In November 2015, the Bipartisan Budget Act of 2015 (the “2015 Act”) was passed, adding 
further clarity for the next two fiscal years, including increases in defense funding.  The passage of the 2014 Act enabled the 
Federal Government to resume a more normalized process for awarding contracts by mid-2014, which served to improve 
leasing activity for our Defense/IT Locations in 2015, and we believe that the passage of the 2015 Act could serve to continue 
this trend.  We believe that the knowledge-based activities of most of our tenants will continue to be a priority in defense 
budgets as such activities are considered increasingly critical to our national security. 

Occupancy for our Regional Office properties as of December 31, 2015 was 95.4% (including properties held for sale), a 
0.3% increase from year-end 2014.  Our Regional Office properties tend to be more subject to general market conditions than 
our Defense/IT Locations.  Of the 24 Regional Office properties owned by us as of December 31, 2015, 13 were held for sale; 
the remaining properties were 97.1% occupied as of December 31, 2015.

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

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

• 
• 
• 

how we expect to generate cash for short and long-term capital needs; 
our off-balance sheet arrangements in place that are reasonably likely to affect our financial condition; and
our commitments and contingencies.

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

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

All of our operating portfolio square footage, occupancy and leasing statistics included below and elsewhere in this Annual 
Report on Form 10-K exclude the effect of the two properties (totaling 665,000 square feet) that served as collateral for debt in 
default; effective April 1, 2014, all cash flows from such properties belonged to the lender.  On August 28, 2015, ownership in 
these properties was transferred to the mortgage lender and we removed the debt obligation and accrued interest from our 
balance sheet.  These properties were 25.1% occupied as of the date we transferred ownership.

Critical Accounting Policies and Estimates  

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

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

Acquisitions of Properties

When we acquire properties, we allocate the purchase price to numerous tangible and intangible components.  Most of the 

terms in this bullet section are discussed in further detail in Note 2 to the consolidated financial statements entitled 
“Acquisitions of Properties.”  Our process for determining the allocation to these components requires many estimates and 
assumptions, including the following: (1) determination of market rental rates; (2) estimation of leasing and tenant 

30

improvement costs associated with the remaining term of acquired leases; (3) assumptions used in determining the in-place 
lease value, if-vacant value and tenant relationship value, including the rental rates, period of time that it would take to lease 
vacant space and estimated tenant improvement and leasing costs; (4) renewal probabilities; and (5) allocation of the if-vacant 
value between land and building.  A change in any of the above key assumptions can materially change not only the 
presentation of acquired properties in our consolidated financial statements but also our reported results of operations.  The 
allocation to different components affects the following:

• 

the amount of the purchase price allocated among different categories of assets and liabilities on our consolidated balance 
sheets; the amount of costs assigned to individual properties in multiple property acquisitions; and the amount of gain 
recognized in our consolidated statements of operations should we determine that the fair value of the acquisition exceeds 
its cost;

• 

•  where the amortization of the components appear over time in our consolidated statements of operations.  Allocations to 
above- and below-market leases are amortized into rental revenue, whereas allocations to most of the other tangible and 
intangible assets are amortized into depreciation and amortization expense.  As a REIT, this is important to us since much 
of the investment community evaluates our operating performance using non-GAAP measures such as funds from 
operations, the computation of which includes rental revenue but does not include depreciation and amortization expense; 
and 
the timing over which the items are recognized as revenue or expense in our consolidated statements of operations.  For 
example, for allocations to the as-if vacant value, the land portion is not depreciated and the building portion is depreciated 
over a longer period of time than the other components (generally 40 years).  Allocations to above- and below-market 
leases, in-place lease value and tenant relationship value are amortized over significantly shorter timeframes, and if 
individual tenants’ leases are terminated early, any unamortized amounts remaining associated with those tenants are 
written off upon termination.  These differences in timing can materially affect our reported results of operations.  In 
addition, we establish lives for tenant relationship values based on our estimates of how long we expect the respective 
tenants to remain in the properties.

Impairment of Long-Lived Assets

We assess each of our operating properties for impairment quarterly using cash flow projections and estimated fair values 

that we derive for each of the properties.  We update the leasing and other assumptions used in these projections regularly, 
paying particular attention to properties that have experienced chronic vacancy or face significant market challenges.  We 
review our plans and intentions for our development projects and land parcels quarterly.  If our analyses indicate that the 
carrying values of operating properties, properties in development or land held for future development may be impaired, we 
perform a recovery analysis for such properties.  For long-lived assets 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 
assets over, in most cases, a ten-year holding period.  If we believe there is a significant possibility that we might dispose of the 
assets 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 assets over the various possible holding periods.  
If the analysis indicates that the carrying value of a tested property is not recoverable from estimated future cash flows, it is 
written down to its 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 each asset using holding 
periods that are consistent with our revised plans.  

Property fair values are estimated based on contract prices, indicative bids, discounted cash flow analyses or yield 
analyses. Estimated cash flows used in such 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 rental rates, occupancies for the tested property 
and comparable properties, estimated operating and capital expenditures and recent sales data for comparable properties; most 
of these items are influenced by market data obtained from real estate leasing and brokerage firms and our direct experience 
with the properties and their markets.  Determining the appropriate capitalization or yield rate also requires significant 
judgment and is typically based on many factors, including the prevailing rate for the market or submarket, as well as the 
quality and location of the properties.  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.

Properties held for sale are carried at the lower of their carrying values (i.e., cost less accumulated depreciation and any 
impairment loss recognized, where applicable) or estimated fair values less costs to sell.  Accordingly, decisions to sell certain 
operating properties, properties in development or land held for development will result in impairment losses if carrying values 
of the specific properties exceed their estimated fair values less costs to sell.  The estimates of fair value consider matters such 

31

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. 

Assessment of Lease Term

As discussed above, a significant portion of our portfolio is leased to the United States Government, and the majority of 
those leases consist of a series of one-year renewal options, or provide for early termination rights.  In addition, certain other 
leases in our portfolio provide early termination rights to tenants.  Applicable accounting guidance requires us to recognize 
minimum rental payments on a straight-line basis over the terms of each lease and to assess the lease terms as including all 
periods for which failure to renew, or continue, the lease imposes a penalty on the lessee in such amounts that renewal, or 
continuation, appears, at the inception of the lease, to be reasonably assured.  Factors we consider when determining whether a 
penalty is significant 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 leasehold improvements or other assets whose value would be impaired by the lessee vacating or 
discontinuing use of the leased property.  For a number of our leases with the United States Government, we have concluded, 
based on the factors above, that exercise of existing renewal options, or continuation of such leases without exercising early 
termination rights, is reasonably assured.  Changes in these assessments could result in the write-off of any recorded assets 
associated with straight-line rental revenue and acceleration of depreciation and amortization expense associated with costs we 
have incurred related to these leases.

Revenue Recognition on Tenant Improvements

Most of our leases involve some form of improvements to leased space.  When we are required to provide improvements 
under the terms of a lease, we need to determine whether the improvements constitute landlord assets or tenant assets.  If the 
improvements are landlord assets, we capitalize the cost of the improvements and recognize depreciation expense associated 
with 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 funded by us as a lease incentive asset and amortize it as a reduction of rental revenue over the term of the lease.  
Our determination of whether improvements are landlord assets or tenant assets also may affect when we commence revenue 
recognition in connection with a lease. 

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

subjective or complex judgments, including: whether the 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.  

Collectability of Accounts and Deferred Rent Receivable

Allowances for doubtful accounts and deferred rent receivable are established based on quarterly analyses of the risk of 
loss on specific accounts.  The analyses place particular emphasis on past-due accounts and consider information such as the 
nature and age of the receivables, the payment history of the tenants, the financial condition of the tenants and our assessment 
of their ability to meet their lease obligations, the basis for any disputes and the status of related negotiations.  Our estimate of 
the required allowance is subject to revision as these factors change and is sensitive to the effects of economic and market 
conditions on tenants.

Activities we conduct to monitor the credit quality of our tenants include the following: monitoring the timeliness of 

tenant lease payments; reviewing credit ratings of tenants that are rated by a nationally recognized credit agency prior to such 
tenants’ entry into leases, and monitoring periodically thereafter; reviewing financial statements of tenants that are publicly 
available or that are required to be provided to us pursuant to the terms of such tenants’ leases; and monitoring news reports 
regarding our tenants.  

Accounting Method for Investments

We use three different accounting methods to report our investments in entities: the consolidation method; the equity 
method; and the cost method (see Note 2 to our consolidated financial statements).  We use the consolidation method when we 
own most of the outstanding voting interests in an entity and can control its operations.  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.  Generally, this applies to entities for which either: (1) the equity investors (if 

32

any) lack one or more of the essential characteristics of a controlling financial interest; (2) the equity investment at risk is 
insufficient to finance that entity's activities without additional subordinated financial support; or (3) the equity investors have 
voting rights that are not proportionate to their economic interests and the activities of the entity involve, or are conducted on 
behalf of, an investor with a disproportionately small voting interest.  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.  

In making these determinations, we need to make subjective estimates and judgments regarding the entity’s future 

operating performance, financial condition, future valuation and other variables that may affect the cash flows of the entity.  We 
must consider both our and our partner's ability to participate in the management of the entity’s operations and make decisions 
that allow the parties to manage their economic risks.  We may also need to estimate the probability of different scenarios 
taking place over time and their effect on the partners’ cash flows.  The conclusion reached as a result of this process affects 
whether or not we use the consolidation method in accounting for our investment or the equity method.  Whether or not we 
consolidate an investment can materially affect our consolidated financial statements.

The increases in the Lackland Air Force Base, Redstone Arsenal and Data Center Shells segments were due to newly 
constructed properties placed in service.  The decrease in Regional Office was due primarily to property dispositions.

Please refer to the section above entitled “Overview” for discussion regarding our leasing activity in 2015 and our expectations 
regarding the future outlook.  As the table above reflects, the increase in our total occupancy from December 31, 2014 to 
December 31, 2015 was attributable primarily to high occupancy rates in newly constructed or redeveloped space placed into 
service and properties acquired during the year.  Occupancy of our Same Office Properties was 90.9% at December 31, 2015, 
up slightly from 90.6% at December 31, 2014.  With regard to our segment occupancy trends, including changes from 
December 31, 2014 to December 31, 2015:

• 

Fort Meade/BW Corridor: Occupancy increased due in large part to a fully-occupied, newly constructed property placed 
into service and occupancy of previously vacated space in connection with new leases.  We renewed 77.1% of the square 
footage of our scheduled lease expirations for the year in this segment.  Fort Meade continues to be among the strongest 
demand drivers of our Defense/IT Locations;

•  Northern Virginia: Occupancy increased due primarily to a property acquired and a newly constructed property placed in 
service, each of which were fully occupied.  Certain of our submarkets in this segment are experiencing weak market 
conditions, including surplus supply for space.  While ten of our 13 properties in this segment had a weighted average 
occupancy rate of 98.0% as of December 31, 2015, the other three properties’ weighted average occupancy rate was 
43.5%.  However, only 73,000, or 4%, of the segment’s square feet had scheduled lease expirations in 2016;

•  Navy Support Locations: Occupancy decreased due primarily to our renewal of 58.7% of the square footage of our 

scheduled lease expirations for the year and placing into service a vacant redeveloped building.  As in Northern Virginia, 
we are also experiencing weak demand in each of our three submarkets comprising this segment, which is creating 
downward pressure on rental rates.  In addition, 208,000, or 16.5%, of the segment’s square feet had scheduled lease 
expirations in 2016; and

•  Redstone Arsenal: Occupancy increased due primarily to occupancy commencing on a previously vacant 62,000 square 

foot property and a fully-occupied, newly constructed property placed into service.

In 2015, we completed 2.5 million square feet of leasing, including 735,000 square feet of construction and redevelopment 

space.  Our construction and redevelopment leasing was highlighted by four data center shells leased in Northern Virginia 
totaling 597,000 square feet and 71,000 square feet leased in a property in the Fort Meade/BW Corridor segment.  As of 
December 31, 2015, we had 1.3 million square feet under construction that were 65% leased and 156,000 under redevelopment 
that were 8% leased.  

In 2015, we renewed leases on 1.3 million square feet, representing 70.6% of the square footage of our lease expirations 

(including the effect of early renewals).  The annualized rents of these renewals (totaling $26.72 per square foot) decreased on 
average by approximately 2.6% and the revenue under GAAP (totaling $27.06 per square foot) increased on average by 
approximately 6.5% relative to the leases previously in place for the space.  The renewed leases had a weighted average lease 
term of approximately 4.3 years and the average estimated tenant improvements and lease costs associated with completing the 
leasing was approximately $12.58 per square foot. 

In 2015, we also completed 515,000 square feet in other leasing, consisting primarily of space previously leased by us to 

tenants that was subsequently vacated (also referred to as re-tenanted space).  The annualized rents of this other leasing totaled 
$25.38 per square foot and the revenue under GAAP totaled $25.86 per square foot; these leases had a weighted average lease 
term of approximately 6.3 years and the average estimated tenant improvements and lease costs associated with completing this 
leasing was approximately $43.49 per square foot.

36

 
Our weighted average lease term for office properties at December 31, 2015 was approximately 4.9 years.  The table below 

sets forth as of December 31, 2015 our scheduled lease expirations of office properties by region in terms of percentage of 
annualized rental revenue:

With regard to leases expiring in 2016, we believe that the weighted average annualized rental revenue per occupied square 
foot for such leases at December 31, 2015 was, on average, approximately 2% to 3% higher than estimated current market rents 
for the related space, with specific results varying by segment.

 The leasing statistics set forth above assume no exercise of any early termination rights.  Most of the leases with our 
largest tenant, the United States Government, provide for consecutive one-year terms; all of the leasing statistics set forth above 
assume that the United States Government will remain in the space that they lease through the end of the respective 
arrangements, without ending consecutive one-year leases prematurely. 

Wholesale Data Center Property

We completed development of our 19.25 megawatt wholesale data center in 2015 and, in February 2015, leased 11.25 

megawatts with occupancy that commenced in stages.  The center became 100% operational during the period.  As of 
December 31, 2015, 17.8 of the center’s megawatts were leased to tenants with further expansion rights of up to a combined 
18.9 megawatts.

Results of Operations

We evaluate the operating performance of our properties using NOI from real estate operations, our segment performance 

measure derived by subtracting property operating expenses from revenues from real estate operations.  We view our NOI from 
real estate operations as comprising the following primary categories of operating properties:

• 

• 
• 

• 
• 
• 

office properties owned and 100% operational throughout the two years being compared, excluding properties held for 
future disposition.  We define these as changes from “Same Office Properties.”  For further discussion of the concept of 
“operational,” you should refer to the section of Note 2 of the consolidated financial statements entitled “Properties”;
office properties acquired during the two years being compared; 
constructed or redeveloped office properties placed into service that were not 100% operational throughout the two years 
being compared;
our wholesale data center;
properties held for sale as of December 31, 2015; and
property dispositions.

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

37

 
 
 
We believe that operating income, as reported on our consolidated statements of operations, is the most directly 

comparable GAAP measure for both NOI from real estate operations and NOI from service operations.  Since both of these 
measures exclude certain items includable in operating 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.

The table below reconciles NOI from real estate operations and NOI from service operations to operating income reported 

on the consolidated statements of operations of COPT and subsidiaries:

NOI from real estate operations
NOI from service operations
NOI from discontinued operations
Depreciation and amortization associated with real

estate operations

Our Same Office Properties pool consisted of 145 office properties, comprising 80.3% of our operating office square 
footage as of December 31, 2015.  This pool of properties included the following changes from the pool used for purposes of 
comparing 2014 and 2013 in our 2014 Annual Report on Form 10-K: the addition of eight properties placed in service and 
100% operational by January 1, 2014; and the removal of 15 properties reclassified to held for sale in 2015, seven properties 
disposed of and one property reclassified as redevelopment in 2015.

Our NOI from constructed and redeveloped office properties placed in service included 14 properties placed in service in 
2014 and 2015, and our NOI from acquired office properties included our acquisitions of 250 W. Pratt Street, 2600 Park Tower 
Drive and 100 and 30 Light Street.

The increase in NOI from our wholesale data center was attributable primarily to higher occupancy in the current period.

39

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Depreciation and Amortization Expense 

The increase in depreciation and amortization expense was attributable primarily to:

• 

• 

additional expense in 2015 of $10.7 million from our office property acquisitions, $4.4 million from properties placed in 
service and $3.1 million from our shortening the useful lives of properties that were removed from service for 
redevelopment; offset in part by
additional expense in 2014 of $12.9 million from our shortening the useful life of a property that was removed from 
service for redevelopment.

Impairment Losses 

The increase in impairment losses was attributable primarily to the following losses recognized in 2015:

• 

• 

$12.8 million on land in Colorado Springs, Colorado.  We classified some of this land as held for sale in the fourth quarter 
of 2015, at which time we adjusted the land to its estimated fair value less costs to sell.  Due to the impairment loss on the 
land held for sale, we updated our estimates of fair value for other land owned in Colorado Springs and determined that the 
carrying value of some of this land exceeded such land’s estimated fair value, which resulted in recognition of an 
additional impairment loss; and
$6.6 million on land in Aberdeen, Maryland.  After concluding in 2015 that we no longer expected to develop operating 
properties on the land, we determined that the carrying amount of the land would not likely be recovered from the sale of 
this property over the likely remaining holding period.  Accordingly, we adjusted the land to its estimated fair value;

General, Administrative and Leasing Expenses

We capitalize compensation and indirect costs associated with properties, or portions thereof, undergoing construction, 
development and redevelopment activities, and also capitalize such costs associated with internal-use software development.  
We also capitalize compensation costs associated with obtaining new tenant leases or extending existing tenants.  Capitalized 
compensation and indirect costs were as follows:

The increase in business development expenses and land carry costs was due primarily to additional expense in 2015 of

Our average outstanding debt increased from $2.0 billion in 2014 to $2.1 billion in 2015, while our weighted average effective 
interest rate on debt under generally accepted accounting principles decreased from 4.6% in 2014 to 4.3% in 2015 (or from 
4.3% in 2014 to 4.0% in 2015 excluding the effect of the default interest on the debt that we extinguished via property 
conveyance).  The overall decrease in interest expense was due primarily to our fixed rate mortgage loans extinguished in 2014 
and 2015 having higher interest rates than our newer debt issuances and borrowings.  The changes reflected in the table above 
also reflect our increased emphasis on unsecured borrowing over mortgage and other secured borrowings.  Interest expense for 
Unsecured Senior Notes increased due to our initial note issuances in May 2014 and June 2015.  Capitalized interest increased 
due primarily to increased volume in active construction and development projects.

Gain (Loss) on Early Extinguishment of Debt

We recognized a gain on early extinguishment of debt of $85.7 million in the current year primarily in connection with our 

transfer of ownership in two properties serving as collateral for a $150.0 million nonrecourse mortgage loan to the mortgage 
lender and the removal of the debt obligation and accrued interest from our balance sheet.  The loss on early extinguishment of 
debt in the prior year was attributable primarily to a $9.1 million loss recognized in connection with the defeasance of, and full 
satisfaction of our obligations with respect to, two secured nonrecourse mortgage loans with a $211.5 million aggregate 
principal amount. 

Gain on Sales of Real Estate, Net

We recognized gain on sales of real estate in 2015 of $64.1 million in connection with office properties dispositions and 
$4.0 million in connection with land sales.  We recognized gain on sales of real estate in 2014 of $5.6 million in connection 
with a land sale and $5.1 million in connection with dispositions of operating properties.

The increases in tenant recoveries and other real estate operations revenue and property operating expenses from our Same 
Office Properties were primarily due to increases in expenses resulting mostly from higher than normal snowfall and lower than 
normal temperatures in the Mid-Atlantic region in 2014 and an increase in certain other directly reimbursable expenses.

Our Same Office Properties pool consisted of 137 office properties, comprising 79.8% of our operating office square 

footage as of December 31, 2014.  This pool of properties changed from the pool used for purposes of comparing 2014 and 
2013 in our 2014 Annual Report on Form 10-K due to the removal of 15 properties reclassified to held for sale in 2015, seven 
property disposed of and one property reclassified as redevelopment in 2015.

Our NOI from constructed office properties placed in service included 13 properties placed in service in 2013 and 2014.

Depreciation and Amortization Expense 

The increase in depreciation and amortization expense was attributable primarily to our shortening of the useful life of a 

property that was removed from service for redevelopment.

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

Impairment Losses 

We recognized the impairment losses described below in 2014 and 2013:

• 

• 

• 

• 

$1.4 million in 2014 primarily in connection with certain of our operating properties in White Marsh, Maryland (included 
in our Regional Office segment) that we decided to sell and whose carrying amounts exceeded the cash flows from the 
operations and sales of the properties over the shortened period.  These properties were subsequently disposed during the 
year;
for certain of our operating properties that served as collateral for a nonrecourse loan, we expected that the cash flows to be 
generated by the properties would be insufficient to fund debt service requirements on the loan.  While we sought to 
negotiate various alternatives with the lender, on December 23, 2013, we conveyed the properties to the lender to 
extinguish the loan.  We recognized non-cash impairment losses of $11.0 million (all classified as discontinued operations 
and including $560,000 in exit costs) on these properties in 2013 resulting primarily from the carrying amount of certain of 
these properties located in Colorado Springs, Colorado (included in our Regional Office and Colorado Defense/IT 
Locations segments) exceeding their fair value; 
$15.2 million in 2013 (all classified as discontinued operations and including $419,000 in exit costs) in connection with 
properties and land no longer aligned with our strategy that we sold, mostly in Colorado Springs (operating properties 
included primarily in our Regional Office and Colorado Defense/IT Locations segments); and
$5.9 million in 2013 on two properties in White Marsh, Maryland (included in our Regional Office segment) that we 
concluded no longer met our investment criteria during the year and whose carrying amounts exceeded the cash flows from 
the operations and sales of the properties over the shortened period.

Aside from the incremental additional interest expense associated with the default rate on debt that was extinguished via 
property conveyance, most of the changes in interest expense reflected above are the result of our emphasis on improving our 
capital position primarily through the repayment of existing borrowings using proceeds from the property sales, public 
offerings of equity and new unsecured borrowings.  Interest expense for Unsecured Senior Notes increased due to our initial 
note issuances in May and September 2013 and an additional issuance in May 2014.  Interest expense for Exchangeable Senior 
Notes decreased due to our repayment of almost all of these notes during 2013.  Capitalized interest decreased due primarily to 
our completion of significant construction and development projects that were not immediately offset by new projects.

Loss on Early Extinguishment of Debt

The loss on early extinguishment of debt in 2014 was attributable primarily to a $9.1 million loss recognized in connection 

with the defeasance of, and full satisfaction of our obligations with respect to, two secured nonrecourse mortgage loans with a 
$211.5 million aggregate principal amount.  The loss on early extinguishment of debt in 2013 was attributable primarily to a 
$25.9 million loss recognized on our repayment of a $239.4 million principal amount of our 4.25% Exchangeable Senior Notes.  

Discontinued Operations

The decrease in discontinued operations was due to a $67.8 million gain on early extinguishment of debt recognized on our 

conveyance of properties to the lender of a non recourse loan to extinguish the loan in December 2013.

Gain on Sales of Real Estate, Net

In 2014, we recognized gain on sales of real estate of $5.6 million in connection with the disposition of a non-operating 
property and $5.1 million in connection with dispositions of operating properties in White Marsh, Maryland.  For 2013, our 
gain on sales of real estate, net (excluding amounts in discontinued operations) included a $6.3 million gain on the substantive 
disposition of our investment in an unconsolidated real estate joint venture and a $2.7 million gain from our disposition of land 
parcels in White Marsh, Maryland.  

Adjusted EBITDA Interest Coverage Ratio and Adjusted EBITDA Fixed Charge Coverage Ratio

Adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”) is net income adjusted for 

the effects of interest expense, depreciation and amortization, impairment losses, gain on sales of properties, gain or loss on 
early extinguishment of debt, net gain on unconsolidated entities, operating property acquisition costs, loss on interest rate 

45

 
 
derivatives, income taxes, business development expenses, demolition costs on redevelopment properties and executive 
transition costs, and excluding the effect of properties serving as collateral for debt which is in default that we extinguished via 
conveyance of such properties.  The adjustment for the effect of properties that served as collateral for debt in default that we 
extinguished via conveyance of such properties pertains to the periods subsequent to our default on the 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 
ownership, all cash flows produced by them went directly to the lender and we did not fund any debt service shortfalls.  In 
2015, we changed our methodology for reporting Adjusted EBITDA to exclude the effect of business development expenses 
since such expenses pertain to the pursuit of new business opportunities rather than normal operations; Adjusted EBITDA for 
prior periods has been revised to conform with the change in methodology.  We believe that Adjusted EBITDA is a useful 
supplemental measure for assessing our un-levered performance.  We believe that net income, as reported on our consolidated 
statements of operations, is the most directly comparable GAAP measure to Adjusted EBITDA.  Adjusted EBITDA excludes 
items that are included in net income, including some that require cash outlays; we compensate for this limitation by using the 
measure simply as a supplemental measure that is considered alongside other GAAP and non-GAAP measures.  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. 

We use Adjusted EBITDA to calculate Adjusted EBITDA Interest Coverage Ratio and Adjusted EBITDA Fixed Charge 

Coverage Ratio.  We calculate Adjusted EBITDA interest coverage by dividing Adjusted EBITDA by interest expense on 
continuing and discontinued operations (excluding amortization of deferred financing costs and amortization of debt discounts 
and premiums, net of amounts capitalized, gains or losses on interest rate derivatives and interest expense on debt in default 
which we have extinguished, or expect to extinguish, via conveyance of properties).  We calculate Adjusted EBITDA fixed 
charge coverage ratio by dividing Adjusted EBITDA by the sum of: (1) interest expense on continuing and discontinued 
operations (excluding amortization of deferred financing costs and amortization of debt discounts and premiums, net of 
amounts capitalized, gains or losses on interest rate derivatives and interest expense on debt in default to be extinguished via 
conveyance of properties); (2) scheduled principal amortization on mortgage loans; (3) capitalized interest; (4) dividends on 
preferred shares; and (5) distributions on preferred units in the Operating Partnership not owned by COPT.

Funds from Operations

Funds from operations (“FFO”) is defined as net income (loss) computed using GAAP, excluding gains on sales of, and 
impairment losses on, previously depreciated operating properties, plus real estate-related depreciation and amortization.  When 
multiple properties consisting of both operating and non-operating properties exist on a single tax parcel, we classify all of the 
gains on sales of, and impairment losses on, the tax parcel as all being for previously depreciated operating properties when 
most of the value of the parcel is associated with operating properties on the parcel.  We believe that we use the National 
Association of Real Estate Investment Trusts (“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 related to sales of, 
and impairment losses on, previously depreciated operating properties, net of related tax benefit, and excluding 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 the 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) depreciation and amortization allocable to noncontrolling interests in other consolidated entities and (5) Basic FFO 
allocable to restricted shares.  With these adjustments, Basic FFO represents FFO available to common shareholders and 
common unitholders.  Common units in the Operating Partnership are substantially similar to our common shares and are 
exchangeable into common shares, subject to certain conditions.  We believe that Basic FFO is useful to investors due to the 
close correlation of common units to common shares.  We believe that net income is the most directly comparable GAAP 
measure to Basic FFO.  Basic FFO has essentially the same limitations as FFO; management compensates for these limitations 
in essentially the same manner as described above for FFO.

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 the numerator for diluted EPS is the most directly comparable GAAP measure to 
Diluted FFO.  Since Diluted FFO excludes certain items includable in the numerator to diluted EPS, reliance on the measure 
has limitations; management compensates for these limitations by using the measure simply as a supplemental measure that is 
weighed in the balance with other GAAP and non-GAAP measures.  Diluted FFO is not necessarily an indication of our cash 
flow available to fund cash needs.  Additionally, it should not be used as an alternative to net income when evaluating our 
financial performance or to cash flow from operating, investing and financing activities when evaluating our liquidity or ability 
to make cash distributions or pay debt service.

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

adjusted to exclude: operating property acquisition costs; gains on sales of, and impairment losses on, properties other than 
previously depreciated operating properties, net of associated income tax; gain or loss on early extinguishment of debt; FFO 
associated with properties securing non-recourse debt on which we have defaulted and which we have extinguished, or expect 
to extinguish, via conveyance of such properties, including property NOI and interest expense (discussed further below); loss 
on interest rate derivatives; demolition costs on redevelopment properties; executive transition costs; and issuance costs 
associated with redeemed preferred shares.  We believe that the excluded items are not reflective of normal operations and, as a 
result, we believe that a measure that excludes these items is a useful supplemental measure in evaluating 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 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 and $5.8 million in 2014.  We believe that the numerator to diluted EPS is the 

48

 
 
 
 
 
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 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 common shares and (b) distributions to holders of interests in COPLP 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.

 Cash Flows

Net cash flow provided by operating activities increased $10.1 million from 2014 to 2015 due primarily to:

• 

• 

• 

• 

a $10.7 million increase in cash flow from real estate operations due primarily to properties acquired and placed in service 
since the prior period;
a $13.3 million decrease in interest expense paid from 2014 to 2015 due in large part to: a $6.4 million decrease in interest 
paid on the $150.0 million nonrecourse loan that was in default (as discussed above) since we did not support payments on 
the loan in 2015; and a $6.0 million decrease due to a change in the timing of interest payments resulting from new debt 
requiring interest payments semi-annually rather than monthly; and
an $8.6 million decrease in payments to early extinguish debt due primarily to our defeasance of mortgage loans in 2014; 
offset in part by
a $17.3 million decrease in cash flow from construction contract and other services from 2014 to 2015 due in large part to 
the timing of cash payments and collections on third party construction projects.

Net cash flow used in investing activities increased $97.8 million from 2014 to 2015 due primarily to operating property 

acquisitions in 2015, offset in part by increased proceeds from sales of properties in 2015.

Net cash flow provided by financing activities in 2015 was $157.8 million and included the following:

• 
• 
• 

• 
• 
• 
• 

net proceeds from debt borrowings of $259.0 million; and
net proceeds from the issuance of common shares (or units) of $28.6 million; offset in part by 
dividends and/or distributions to shareholders and/or unitholders of $122.6 million. 

Net cash flow used in financing activities in 2014 was $32.5 million and included the following:

net proceeds from the issuance of common shares (or units) of $150.2 million; offset in part by
net repayments of borrowings of $9.3 million; 
redemption of preferred shares (or units) of $50.0 million; and
dividends and/or distributions to shareholders and/or unitholders of $118.1 million.

Liquidity and Capital Resources of COPT

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

As of December 31, 2015, COPT owned 96.3% of the outstanding common units and 95.5% of the outstanding preferred 
units in COPLP; the remaining common and preferred units in COPLP 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. 

52

 
 
 
 
 
 
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 elsewhere 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, we believe the Operating Partnership’s sources of working capital, specifically its cash flow 

from operations, and borrowings available under its unsecured line of credit, 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 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, acquisitions and developments.

Liquidity and Capital Resources of COPLP

Our primary cash requirements are for operating expenses, debt service, development of new properties, improvements to 

existing properties and acquisitions.  We expect to continue to use cash flow provided by operations as the primary source to 
meet our short-term capital needs, including property operating expenses, general and administrative expenses, interest 
expense, scheduled principal amortization of debt, distributions to our security holders and improvements to existing 
properties.  As of December 31, 2015, we had $60.3 million in cash and cash equivalents; most of this balance was attributable 
to $57.2 million in cash held from dispositions as of December 31, 2015 that we expect to use in 2016 to fund development 
activities.  

Our senior unsecured debt is currently 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, 
when appropriate.  In addition, we periodically access the public equity markets to raise capital by issuing common and/or 
preferred shares.  

We use our Revolving Credit Facility to initially finance much of our investing activities.  We subsequently pay down the 
facility using proceeds from long-term borrowings, equity issuances and property sales.  The lenders’ aggregate commitment 
under the facility is $800.0 million, with the ability for us to increase the lenders’ aggregate commitment to $1.3 billion, 
provided that there is no default under the facility and subject to the approval of the lenders.  Amounts available under the 
facility are computed based on 60% of our unencumbered asset value, as defined in the loan agreement.  The Revolving Credit 
Facility matures in May 2019, and may be extended by two six-month periods at our option, provided that there is no default 
under the facility and we pay an extension fee of 0.075% of the total availability of the facility.  As of December 31, 2015, the 
maximum borrowing capacity under this facility totaled $800.0 million, of which $741.7 million was available.  

We believe that our liquidity and capital resources are adequate for our near-term and longer-term requirements without 
necessitating property sales.  We do, however, expect to raise at least $440 million from sales of properties in 2016 and use the 
proceeds to repay borrowings and fund development costs.

(1)  The contractual obligations set forth in this table exclude property operations contracts that may be terminated with notice of one month 

or less.

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

financing costs of $19.5 million.  We expect to repay most of our debt maturing in 2016 using proceeds from a term loan with $150.0 
million in available capacity that we entered into in December 2015.  As of December 31, 2015, maturities include $43.5 million in 2019 
that may be extended to 2020, subject to certain conditions.  

(3)  Represents interest costs for our outstanding debt as of December 31, 2015 for the terms of such debt.  For variable rate debt, the 

amounts reflected above used December 31, 2015 interest rates on variable rate debt in computing interest costs for the terms of such 
debt.

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

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

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

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

(7)  Represents contractual obligations pertaining to recurring and nonrecurring capital expenditures for our operating properties.  We expect 

to finance these costs primarily using cash flow from operations.

(8)   We expect to pay these items using cash flow from operations.

We expect to spend approximately $250.0 million on construction and development costs and approximately $60.0 
million on improvements to operating properties (including the commitments set forth in the table above) in 2016.  We expect 
to fund the construction and development costs using primarily cash on hand and borrowings under our Revolving Credit 
Facility.  We expect to use proceeds from the disposition of properties to repay borrowings under our Revolving Credit Facility.  
We expect to fund improvements to existing operating properties using cash flow from operations. 

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, 
2015, we were in compliance with these financial covenants.

Off-Balance Sheet Arrangements

We had no material off-balance sheet arrangements during 2015.

Inflation

Most of our tenants are obligated to pay their share of a building’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.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued guidance regarding the recognition of revenue 
from contracts with customers.  Under this guidance, an entity will recognize revenue to depict the transfer of goods or services 
to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods 
or services.  Additionally, this guidance requires improved disclosures regarding the nature, amount, timing and uncertainty of 
revenue and cash flows arising from contracts with customers.  We are required to adopt this guidance for our annual and 
interim periods beginning January 1, 2018 using one of two methods: retrospective restatement for each reporting period 
presented at the time of adoption, or retrospectively with the cumulative effect of initially applying this guidance recognized at 
the date of initial application.  We are currently assessing the financial impact of this guidance on our consolidated financial 
statements.

In January 2015, the FASB issued guidance regarding the presentation of extraordinary and unusual items in statements of 

operations.  This guidance eliminates the concept of extraordinary items. However, the presentation and disclosure 
requirements for items that are either unusual in nature or infrequent in occurrence remain and will be expanded to include 
items that are both unusual in nature and infrequent in occurrence. This guidance is effective for periods beginning after 
December 15, 2015.  We expect that the application of this guidance will have no effect on our reported consolidated financial 
statements.

In February 2015, the FASB issued guidance regarding amendments to the consolidation analysis.  This guidance amends 
the criteria for determining which entities are considered variable interest entities (“VIE”), amends the criteria for determining 
if a service provider possesses a variable interest in a VIE and ends the deferral granted to investment companies for 
application of the VIE consolidation model.  This guidance is effective for annual periods, and interim periods therein, 
beginning after December 15, 2015.  We are currently assessing the financial impact of this guidance on our consolidated 
financial statements.

In April 2015, the FASB issued guidance that changes the presentation of debt issuance costs in financial statements.  This 
guidance requires an entity to present such costs in the balance sheet as a direct deduction from the related debt liability rather 
than as an asset.  Amortization of the costs will continue to be reported as interest expense.  This guidance was further updated 
in August 2015 with respect to debt issuance costs of line-of-credit arrangements to note that it will be permissible for an entity 
to defer and present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratably over the 
term of a line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit 
arrangement.  This guidance is effective for annual reporting periods beginning after December 15, 2016.  Early adoption is 
permitted.  We early adopted this guidance in December 2015 and it was applied retrospectively to each prior period presented.  
The application of this guidance did not materially affect our consolidated financial statements.

In September 2015, the FASB issued guidance that eliminates the requirement to restate prior period financial statements 
for measurement period adjustments following a business combination.  The guidance requires that the cumulative impact of a 
measurement period adjustment (including the impact on prior periods) be recognized in the reporting period in which the 
adjustment is identified. The prior period impact of the adjustment should be either presented separately on the face of the 
statement of operations or disclosed in the notes.  This guidance is effective for annual reporting periods beginning after 
December 15, 2015.  This guidance will be applied prospectively for measurement period adjustments that occur after the 
effective date.  We expect that the application of this guidance will not materially affect our consolidated financial statements.

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.

(1)  The notional amount of this instrument is scheduled to amortize to $12.1 million.

Based on our variable-rate debt balances, including the effect of interest rate swap contracts, our interest expense would 
have increased by $2.5 million in 2015 and $1.9 million in 2014 if short-term interest rates were 1% higher.  Interest expense in 
2015 was more sensitive to a change in interest rates than 2014 due primarily to our having a higher average variable-rate debt 
balance in 2015.

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

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

performing an assessment of the effectiveness of internal control over financial reporting as of December 31, 2015.  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, 2015 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, 2015 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, 2015 has been audited by 

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

Report of Independent Registered Public Accounting Firm 

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

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the 
financial position of Corporate Office Properties Trust and its subsidiaries at December 31, 2015 and December 31, 2014, and 
the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015 in 
conformity with accounting principles generally accepted in the United States of America.  In addition, in our opinion, the 
financial statement schedules listed in the accompanying index present fairly, in all material respects, the information set forth 
therein when read in conjunction with the related consolidated financial statements.  Also in our opinion, the Company 
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on 
criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (COSO).  The Company’s management is responsible for these financial statements and financial 
statement schedules, 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 these financial statements, on the financial 
statement schedules, and on the Company’s internal control over financial reporting based on our integrated audits.  We 
conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  
Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial 
statements are free of material misstatement and whether effective internal control over financial reporting was maintained in 
all material respects.  Our audits of the financial statements included examining, on a test basis, evidence supporting the 
amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by 
management, and evaluating the overall financial statement presentation.  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.

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 directors 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.

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.

As discussed in Note 2 to the consolidated financial statements, the Company adopted accounting standards update (“ASU”) 
No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”, which changed 
the criteria for reporting discontinued operations in 2014.

Notes to Consolidated Financial Statements

1. 

Organization

Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company”) is a fully-integrated and self-
managed real estate investment trust (“REIT”).  Corporate Office Properties, L.P. (“COPLP”) and subsidiaries (collectively, the 
“Operating Partnership”) is the entity through which COPT, the sole general partner of COPLP, conducts almost all of its 
operations and owns almost all of its assets.  Unless otherwise expressly stated or the context otherwise requires, “we”, “us” 
and “our” as used herein refer to each of the Company and the Operating Partnership.  We own, manage, lease, develop and 
selectively acquire office and data center properties.  The majority of our portfolio is in locations that support United States 
Government agencies and their 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 complementary portfolio of traditional office properties located in select urban/urban-like submarkets within our regional 
footprint with durable Class-A office fundamentals and characteristics, as well as other properties supporting general 
commercial office tenants (“Regional Office”).  As of December 31, 2015, our properties included the following (all references 
to number of properties, square footage, acres and megawatts are unaudited):

• 

• 

• 
• 

177 operating office properties totaling 18.1 million square feet, including nine triple-net leased, single-tenant data center 
properties;
13 office properties under, or contractually committed for, construction or redevelopment that we estimate will total 
approximately 1.5 million square feet upon completion, including one partially operational property included above;
1,439 acres of land we control that we believe are potentially developable into approximately 17.6 million square feet; and
a wholesale data center with a critical load of 19.25 megawatts.

COPLP owns real estate both 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 and 
construction and development 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, 2015, COPT owned 96.3% 

of the outstanding COPLP common units (“common units”) and 95.5% of the outstanding COPLP preferred units (“preferred 
units”); the remaining common and preferred units in COPLP were owned by third parties.  Common units in COPLP not 
owned by COPT carry certain redemption rights.  The number of common units in COPLP owned by COPT is equivalent to the 
number of outstanding common shares of beneficial interest (“common shares”) of COPT, and the entitlement of all COPLP 
common units to quarterly distributions and payments in liquidation is substantially the same as those of COPT common 
shareholders.  Similarly, in the case of each series of preferred units in COPLP held by COPT, there is 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, and although, as a partnership, COPLP does not have a board of 
trustees, we refer to COPT’s Board of Trustees as COPLP’s Board of Trustees.

2.  

Summary of Significant Accounting Policies

Basis of Presentation

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

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

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

cannot control the entity’s operations.  We discontinue equity method accounting if our investment in an entity (and net 

F-18

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

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.

We use the cost method of accounting when we own an interest in an entity and cannot exert significant influence over its 

operations.

Reclassification

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

financial statements, including amounts related to our adoption of guidance regarding the presentation of deferred debt issuance 
costs (discussed below) and our change in reportable segments (discussed in Note 17), 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 at the dates of the financial statements; 
the disclosure of contingent assets and liabilities at 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 allocation of property acquisition costs, the 
determination of estimated useful lives of assets, the determination of lease terms, the evaluation of impairment of long-lived 
assets, the amount of impairment losses recognized, the 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.  

Acquisitions of Properties

Upon completion of 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 property 
acquisitions to the following components:

• 

• 

• 

• 

properties based on a valuation performed under the assumption that the property is vacant upon acquisition (the “if-vacant 
value”).  The if-vacant value is allocated between land and buildings or, in the case of properties under development, 
construction in progress.  We also allocate additional amounts to properties for in-place tenant improvements based on our 
estimate of improvements per square foot provided under market leases that would be attributable to the remaining non-
cancelable terms of the respective leases;
above- and below-market lease intangible assets or liabilities based on the present value (using an interest rate which reflects 
the risks associated with the leases acquired) of the difference between: (1) the contractual amounts to be received pursuant 
to the in-place leases; and (2) our estimate of fair market lease rates for the corresponding space, measured over a period 
equal to the remaining non-cancelable term of the lease.  The capitalized above- and below-market lease values are 
amortized as adjustments to rental 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

F-19

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

• 

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.

Intangible Assets and Deferred Revenue on Real Estate Acquisitions

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

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

Above- and below-market cost arrangements

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

space in property
Term of arrangements

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

Properties

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

The preconstruction 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 which are essential to development.  

We capitalize interest expense, real estate taxes and direct and indirect project costs (including related compensation and 
other indirect costs) associated with properties, or portions thereof, undergoing construction, development and redevelopment 
activities.  In capitalizing interest expense, if there is a specific borrowing for the property undergoing construction, development 
and 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 construction, 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-constructed 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 construction.  We start depreciating 
newly-constructed and redeveloped properties as they become operational.  

Most of our leases involve 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 the useful life of the assets or the term of the lease and recognize any payments from 
the tenant as rental revenue over the term of the lease.  If the improvements are tenant assets, we defer the cost of improvements 
funded by us as a lease incentive asset and amortize it as a reduction of rental revenue over the term of the lease.  In determining 
whether improvements constitute landlord or tenant assets, we consider numerous factors, including: whether the 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.

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

Buildings and building improvements
Land improvements
Tenant improvements on operating properties
Equipment and personal property

Estimated Useful Lives

10-40 years
10-20 years
Related lease term
3-10 years

We assess each of our operating properties for impairment quarterly using cash flow projections and estimated fair values 

that we derive for each of the properties.  We update the leasing and other assumptions used in these projections regularly, 
paying particular attention to properties that have experienced chronic vacancy or face significant market challenges.  We review 
our plans and intentions for our development projects and land parcels quarterly.  If our analyses indicate that the carrying values 
of operating properties, properties in development or land held for future development may be impaired, we perform a recovery 
analysis for such properties.  For long-lived assets 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 assets over, in most 
cases, a ten-year holding period.  If we believe there is a significant possibility that we might dispose of the assets 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 assets over the various possible holding periods.  If the recovery 
analysis indicates that the carrying value of a tested property is not recoverable from estimated future cash flows, it is written 
down to its 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 each asset using holding 
periods that are consistent with our revised plans.  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 sales 

comparison approach. Estimated cash flows used in such analyses are based on our plans for the property and our views of 
market and economic conditions. The estimates consider factors such as current and future rental rates, occupancies for the tested 
property and comparable properties, estimated operating and capital expenditures and recent sales data for comparable 
properties; most of these factors are influenced by market data obtained from real estate leasing and brokerage firms and our 
direct experience with the properties and their markets.

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

net of selling costs; if we then determine that the estimated fair value, net of selling costs, is less than the net book value of the 
property, we recognize an impairment loss equal to the difference and reduce the net book value of the property.  For periods in 
which a property is classified as held for sale, we classify the assets of the property as held for sale on our consolidated balance 
sheet for such periods.

For dispositions of operating properties occurring prior to June 30, 2014 in which we had no significant continuing 

involvement, or for operating properties held for sale prior to June 30, 2014, we classify the results of operations for such 
properties as discontinued operations; interest expense that is specifically identifiable to properties included in discontinued 
operations is used in the computation of interest expense attributable to discontinued operations.  We adopted guidance issued by 
the Financial Accounting Standards Board (“FASB”) related to the reporting of discontinued operations and disclosures of 
disposals of components of an entity effective for the quarterly period ended June 30, 2014.  This guidance defines a 
discontinued operation as a component or group of components disposed or classified as held for sale that represents a strategic 
shift that has (or will have) a major effect on an entity’s operations and financial results; the guidance states that a strategic shift 
could include a disposal of a major geographical area of operations, a major line of business, a major equity method investment 
or other major parts of an entity.  We have had no properties newly classified as discontinued operations subsequent to our 
adoption of this guidance.

Sales of Interests in Real Estate

We recognize gains from sales of interests in real estate using the full accrual method, provided that various criteria relating 

to the terms of sale and any subsequent involvement by us with the real estate sold are met.

Notes to Consolidated Financial Statements (Continued)

Cash and Cash Equivalents

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

Investments in Marketable Securities

We classify marketable securities as trading securities when we have the intent to sell such securities in the near term, and 
classify other marketable securities as available-for-sale securities.  We determine the appropriate classification of investments in 
marketable securities at the acquisition date and re-evaluate the classification at each balance sheet date.  We report investments 
in marketable securities classified as trading securities at fair value, 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. 

Accounts and Deferred Rents Receivable and Investing Receivables

We maintain allowances for estimated losses resulting from the failure of our customers or borrowers to satisfy their 
payment obligations.  We use judgment in estimating these allowances based primarily upon the payment history and credit 
status of the entities associated with the individual receivables.  We write off these 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 established allowances, we reduce the amount of losses previously recognized.

We evaluate the collectibility of both interest and principal of loans whenever events or changes in circumstances indicate 
such amounts may not be recoverable.  A loan is impaired when it is probable that 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.

Deferred Leasing and Financing Costs

We defer costs incurred to obtain new tenant leases or extend existing tenant leases, including related compensation costs.  

We amortize these costs evenly over the lease terms.  When tenant leases are terminated early, we expense any unamortized 
deferred leasing costs associated with those leases over the shortened term of the lease.  

We defer costs of financing arrangements and recognize these costs as interest expense over the related loan 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.  

 In April 2015, the FASB issued guidance that changes the presentation of deferred debt issuance costs in financial 

statements.  This guidance requires an entity to present such costs in the balance sheet as a direct deduction from the related debt 
liability rather than as an asset.  This guidance was further updated in August 2015 with respect to debt issuance costs of line-of-
credit arrangements to note that it will be permissible for an entity to defer and present debt issuance costs as an asset and 
subsequently amortize the deferred debt issuance costs ratably over the term of a line-of-credit arrangement, regardless of 
whether there are any outstanding borrowings on the line-of-credit arrangement.  We adopted this guidance effective for the 
quarterly period ended December 31, 2015 retrospectively to each prior period presented.  The application of this guidance 
changed the balance sheet classification of most of our deferred financing costs but did not otherwise affect our consolidated 
financial statements.  For costs of such arrangements attributable to line-of-credit arrangements and interest rate derivatives, we 
present such costs in the balance sheet in the line entitled prepaid and other assets.

Noncontrolling Interests

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

in Note 14) and consolidated real estate joint ventures (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.  For noncontrolling interests that are currently redeemable for cash at 
the option of the holders of such interests or deemed probable to eventually become redeemable, we classify such interests as 
redeemable noncontrolling interests in the mezzanine section of our consolidated balance sheets; we adjust these interests each 
period to the greater of their fair value or carrying amount (initial amount as adjusted for allocations of income and losses and 
contributions and distributions), with a corresponding offset to additional paid-in capital on COPT’s consolidated balance sheets 
or common units on COPLP’s balance sheet, and only recognize reductions in such interests to the extent of their carrying 
amount.  Our other noncontrolling interests are reported in the equity section of our consolidated balance sheets.  The amounts 
reported for noncontrolling interests on our consolidated statements of operations represent the portion of these entities’ income 
or losses not attributable to us.

Revenue Recognition

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

generally commences when: (1) the tenant has control of the leased space (legal right to use the property); and (2) we have 
delivered the premises to the tenant as required under the terms of such lease.  The term of a lease generally includes periods 
when a tenant: (1) may not terminate its lease obligation early; (2) may terminate its lease obligation early in exchange for a fee 
or penalty that we consider material enough such that termination would not be probable; (3) possesses renewal rights and the 
tenant’s failure to exercise such rights imposes a penalty on the tenant material enough such that renewal appears reasonably 
assured; or (4) possesses bargain renewal options for such periods.  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 included in deferred revenue 
associated with operating leases on our consolidated balance sheets.  

In connection with a tenant’s entry into, or modification of, a lease, if we make cash payments to, or on behalf of, the tenant 

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

We recognize tenant recovery revenue in the same periods in which we incur the related expenses.  Tenant recovery revenue 

includes payments from tenants as reimbursement for property taxes, utilities and other property operating expenses.

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

We recognize fees for services provided by us once services are rendered, fees are determinable and collectability is assured.  

We recognize revenue under construction contracts using the percentage of completion method when the revenue and costs for 
such contracts can be estimated with reasonable accuracy; when these criteria do not apply to a contract, we recognize revenue 
on that contract using the completed contract method.  Under the percentage of completion method, we recognize a percentage 
of the total estimated revenue on a contract based on the cost of services provided on the contract as of a point in time relative to 
the total estimated costs on the contract.

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 primarily 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.  Derivatives are used to hedge the cash flows associated with interest rates on existing debt as well as future 
debt.  We recognize all derivatives as assets or liabilities on our consolidated balance sheet at fair value.  We defer the effective 
portion of changes in fair value of the designated cash flow hedges to AOCI and reclassify such deferrals to interest expense as 
interest expense is recognized on the hedged forecasted transactions.  We recognize the ineffective portion of the change in fair 
value of interest rate derivatives directly in interest expense.  When an interest rate swap designated as a cash flow hedge no 
longer qualifies for hedge accounting, we recognize changes in fair value of the hedge previously deferred to AOCI, 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. 

Please refer to Note 11 for additional information pertaining to interest rate derivatives.

Expense Classification

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

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

We classify as general and 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, director and officers and key man life) and leasing prospects, as well as associated labor and indirect costs 
attributable to these costs.

Share-Based Compensation

We issue three forms of share-based compensation: restricted COPT common shares (“restricted shares”), deferred share 
awards and performance share units (“PSUs”).  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 award on the grant date; such cost is then recognized over the period during 
which the employee is required to provide service in exchange for the award.  No compensation cost is recognized for equity 
instruments for which employees do not render the requisite service.  The guidance also requires that share-based compensation 
be computed based on awards that are ultimately expected to vest; as a result, future forfeitures of awards are estimated at the 
time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.  If an award is 
voluntarily cancelled by an employee, we recognize the previously unrecognized cost associated with the original award on the 
date of such cancellation.  We capitalize costs associated with share-based compensation attributable to employees engaged in 
construction and development activities. 

When we adopted the authoritative guidance on accounting for share-based compensation, we elected to adopt the 
alternative transition method for calculating the tax effects of share-based compensation.  This method enabled us to use a 
simplified method to establishing the beginning balance of the additional paid-in capital pool related to the tax effects of 

F-24

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

employee share-based compensation that was available to absorb tax deficiencies recognized subsequent to the adoption of this 
guidance.

We compute the fair value of restricted shares and deferred share awards based on the fair value of COPT common shares  

on the grant date.

We compute the fair value of options using the Black-Scholes option-pricing model.  Under that model, the risk-free interest 

rate is based on the U.S. Treasury yield curve in effect at the time of grant.  The expected option life is based on our historical 
experience of employee exercise behavior.  Expected volatility is based on historical volatility of COPT common shares.  
Expected dividend yield is based on the average historical dividend yield on our common shares over a period of time ending on 
the grant date of the options.

We compute the fair value of PSUs using a Monte Carlo model.  Under that model, the baseline common share value is 
based on 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.  Expected volatility is based on historical volatility of COPT’s common shares.

Income Taxes 

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

COPLP is a limited partnership and is not subject to federal income tax.  Its partners are required to report their respective 
share of the Operating Partnership’s taxable income on their respective tax returns.  COPT’s share of the Operating Partnership’s 
taxable income is reported on COPT’s income tax return.

For Federal income tax purposes, dividends to shareholders may be characterized as ordinary income, capital gains or return 

of capital.  The characterization of dividends paid on COPT’s common and preferred shares during each of the last three years 
was as follows:

Ordinary income
Long-term capital gain
Return of capital

Common Shares
For the Years Ended December 31,
2014
64.5%
6.5%
29.0%

2015

2015
38.3%

0.0%

2013
76.2%
23.8%
0.0%

In addition, dividends paid on January 15, 2016 (with a record date of December 31, 2015) on COPT’s common and preferred 
shares were allocated to 2015 for Federal income tax purposes and characterized based on the percentages set forth above for 
2015.

We distributed all of COPT’s REIT taxable income in 2015, 2014 and 2013 and, as a result, did not incur Federal income tax 

in those years. 

The net basis of our consolidated assets and liabilities for tax reporting purposes was approximately $224 million lower than 
the amount reported on our consolidated balance sheet at December 31, 2015, which was primarily related to differences in basis 
for net properties, intangible assets on property acquisitions and deferred rent receivable.

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

Recent Accounting Pronouncements

In May 2014, the FASB issued guidance regarding the recognition of revenue from contracts with customers.  Under this 

guidance, an entity will recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the 
consideration to which the entity expects to be entitled in exchange for those goods or services.  Additionally, this guidance 
requires improved disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from 
contracts with customers.  We are required to adopt this guidance for our annual and interim periods beginning January 1, 2018 
using one of two methods: retrospective restatement for each reporting period presented at the time of adoption, or 
retrospectively with the cumulative effect of initially applying this guidance recognized at the date of initial application.  We are 
currently assessing the financial impact of this guidance on our consolidated financial statements.

In January 2015, the FASB issued guidance regarding the presentation of extraordinary and unusual items in statements of 
operations.  This guidance eliminates the concept of extraordinary items.  However, the presentation and disclosure requirements 
for items that are either unusual in nature or infrequent in occurrence remain and will be expanded to include items that are both 
unusual in nature and infrequent in occurrence.  This guidance is effective for periods beginning after December 15, 2015.  We 
expect that the application of this guidance will have no effect on our reported consolidated financial statements.

In February 2015, the FASB issued guidance regarding amendments to the consolidation analysis.  This guidance amends 
the criteria for determining which entities are considered variable interest entities (“VIE”), amends the criteria for determining if 
a service provider possesses a variable interest in a VIE and ends the deferral granted to investment companies for application of 
the VIE consolidation model.  This guidance is effective for annual periods, and interim periods therein, beginning after 
December 15, 2015.  We are currently assessing the financial impact of this guidance on our consolidated financial statements.

As discussed further above, we adopted guidance issued by the FASB effective for the quarterly period ended December 31, 

2015 retrospectively to each prior period presented that requires an entity to present deferred debt issuance costs (other than 
costs of line-of-credit arrangements) in the balance sheet as a direct deduction from the related debt liability rather than as an 
asset.

In September 2015, the FASB issued guidance that eliminates the requirement to restate prior period financial statements for 

measurement period adjustments following a business combination.  The guidance requires that the cumulative impact of a 
measurement period adjustment (including the impact on prior periods) be recognized in the reporting period in which the 
adjustment is identified. The prior period impact of the adjustment should be either presented separately on the face of the 
statement of operations or disclosed in the notes.  This guidance is effective for annual reporting periods beginning after 
December 15, 2015.  This guidance will be applied prospectively for measurement period adjustments that occur after the 
effective date.  We expect that the application of this guidance will not materially affect our consolidated financial statements.

Fair Value Measurements

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

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

Recurring Fair Value Measurements 

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

participants to defer up to 100% of their compensation on a pre-tax basis and receive a tax-deferred return on such deferrals.  
The assets held in the plan (comprised primarily of mutual funds and equity securities) and the corresponding liability to the 
participants are measured at fair value on a recurring basis on COPT’s consolidated balance sheet using quoted market prices, 
as are other marketable securities that we hold.  The balance of the plan, which was fully funded, totaled $5.8 million as of 
December 31, 2015 and $5.9 million as of December 31, 2014, and is included in the accompanying COPT consolidated 
balance sheets in the line entitled restricted cash and marketable securities.  The offsetting liability associated with the plan is 
adjusted to fair value at the end of each accounting period based on the fair value of the plan assets and reported in other 
liabilities on COPT’s consolidated balance sheets.  The assets of the plan and other marketable securities that we hold are 
classified in Level 1 of the fair value hierarchy.  The liability associated with the plan 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, 
2015, we assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivatives 
and determined that these adjustments are not significant.  As a result, we determined that our interest rate derivative valuations 
in their entirety are classified in Level 2 of the fair value hierarchy.

As discussed further in Note 6, our partners in two real estate joint ventures, LW Redstone Company, LLC and Stevens 
Investors, LLC, have the right to require us to acquire their respective interests at fair value; accordingly, we classify the fair 
value of our partners’ interests as redeemable noncontrolling interests in the mezzanine section of our consolidated balance 
sheet.  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, occupancies for the properties and comparable properties and estimated operating and capital expenditures.  

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.  As discussed in Note 8, we estimated the fair values of our investing receivables 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 and exchangeable senior notes based on quoted market rates for publicly-traded debt (categorized 
within Level 2 of the fair value hierarchy) and estimated the fair value of our other debt based on the discounted estimated 
future cash payments to be made on such debt (categorized within Level 3 of the fair value hierarchy); the discount rates used 
approximate current market rates for loans, or groups of loans, with similar maturities and credit quality, and the estimated 
future payments include scheduled principal and interest payments.  Fair value estimates are made at 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, please refer to Note 8 for investing receivables, Note 10 for debt and Note 11 for 

interest rate derivatives.

Nonrecurring Fair Value Measurements

In 2015, we recognized the following impairment losses resulting from nonrecurring fair value measurements:

• 

• 

• 

• 

$12.8 million on land in Colorado Springs, Colorado (“Colorado Springs”).  We classified some of this land as held for sale 
in the fourth quarter of 2015, at which time we adjusted the land to its estimated fair value less costs to sell.  Due to the 
impairment loss on the land held for sale, we updated our estimates of fair value for other land owned in Colorado Springs 
and determined that the carrying value of some of this land exceeded such land’s estimated fair value, which resulted in 
recognition of an additional impairment loss;
$6.6 million on land in Aberdeen, Maryland.  After concluding during the fourth quarter that we no longer expected to 
develop operating properties on the land, we determined that the carrying amount of the land would not likely be recovered 
from the sale of this property over the likely remaining holding period.  Accordingly, we adjusted the land to its estimated 
fair value;
$2.6 million on operating properties in White Marsh, Maryland (included in our Regional Office segment) that we decided 
to sell and whose carrying amounts exceeded their estimated fair values less costs to sell.  These properties were 
reclassified as held for sale during the year; and
$1.3 million on an operating property in Northern Virginia (included in our Regional Office segment) that we sold on July 
27, 2015 following receipt of an unsolicited offer.  This property’s carrying value exceeded its fair value less costs to sell.

In 2014, we recognized impairment losses totaling $1.4 million primarily in connection with certain of our operating 

properties in White Marsh, Maryland (included in our Regional Office segment) that we decided to sell and whose carrying 
amounts exceeded the cash flows from the operations and sales of the properties over the shortened period.  These properties 
were subsequently disposed during the year.

In 2013, we recognized the following impairment losses:

• 

• 

• 

for certain of our operating properties that served as collateral for a nonrecourse loan, we expected that the cash flows to be 
generated by the properties would be insufficient to fund debt service requirements on the loan.  While we sought to 
negotiate various alternatives with the lender, on December 23, 2013, we conveyed the properties to the lender to 
extinguish the loan.  We recognized non-cash impairment losses of $11.0 million (all classified as discontinued operations 
and including $560,000 in exit costs) on these properties in 2013 resulting primarily from the carrying amount of certain of 
these properties located in Colorado Springs (included in our Regional Office and Colorado Defense/IT Locations 
segments) exceeding their fair value; 
$15.2 million (all classified as discontinued operations and including $419,000 in exit costs) in connection with properties 
and land no longer aligned with our strategy that we sold, mostly in Colorado Springs (operating properties included 
primarily in our Regional Office and Colorado Defense/IT Locations segments); and
$5.9 million on two properties in White Marsh, Maryland (included in our Regional Office segment) that we concluded no 
longer met our investment criteria during the year and whose carrying amounts exceeded the cash flows from the 
operations and sales of the properties over the shortened period.

Concentration of Revenue

A large concentration of our revenue from real estate operations was earned from our largest tenant, the United States 

Government, including 20% of our rental revenue in 2015, 18% in 2014 and 18% in 2013 (continuing and discontinued 
operations, and excluding tenant recoveries and other real estate operations revenue). Our rental revenue from the United States 
Government was earned primarily from properties in the Fort Meade/Baltimore Washington Corridor, Lackland Air Force Base, 
Navy Support Locations and Redstone Arsenal business subsegments (see Note 17).  No other individual tenants accounted for 
10% or more of our revenue from real estate operations.  In addition, we also derived in excess of 90% of our construction 
contract revenue from the United States Government in each of the years set forth on the consolidated statements of operations.

• 

•

On August 28, 2015, ownership in 15000 and 15010 Conference Center Drive was transferred to the mortgage lender on a 
$150.0 million nonrecourse mortgage loan that was secured by the properties and we removed the debt obligation and accrued 
interest from our balance sheet.  Upon completion of this transfer, we recognized a gain on early extinguishment of debt of 
$84.8 million, representing the difference between the mortgage loan and accrued interest payable extinguished over the 
carrying value of the properties transferred as of the transfer date and related closing costs.

2015 Construction Activities

In 2015, we placed into service an aggregate of 897,000 square feet in seven newly constructed office properties and

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

With regard to our consolidated joint ventures:

• 

• 

• 

For LW Redstone, LLC, we anticipate funding certain infrastructure costs (up to a maximum of $76.0 million excluding 
accrued interest thereon) due to be reimbursed by the City of Huntsville as discussed further in Note 8; as of December 31, 
2015, we had advanced $37.2 million to the City to fund such costs (excluding accrued interest; the aggregate amount 
outstanding under these notes, including accrued interest, was $44.9 million as of December 31, 2015 and is included in 
investing receivables on our consolidated balance sheets).  We also expect to fund additional development and construction 
costs through equity contributions to the extent that third party financing is not obtained.  Our partner was credited with a 
$9.0 million capital account upon formation and is not required to make any future equity contributions.  While net cash 
flow distributions to the partners vary depending on the source of the funds distributed, cash flows are generally distributed 
as follows:
• 

cumulative preferred returns on capital invested to fund the project’s infrastructure costs on a pro rata basis to us and 
our partner;
cumulative preferred returns on our capital invested to fund the project’s vertical construction;
return of our invested capital;
return of our partner’s capital;
any remaining residual 85% to us and 15% to our partner.

• 
• 
• 
• 
Our partner has the right to require us to acquire its interest for fair value beginning in March 2020; accordingly, we 
classify the fair value of our partner’s interest as redeemable noncontrolling interests in the mezzanine section of our 
consolidated balance sheet.  We have the right to purchase our partner’s interest at fair value upon the earlier of five years 
following the project’s achievement of a construction commencement threshold of 4.4 million square feet or March 2040; 
the project had achieved 594,000 square feet of construction commencement through December 31, 2015; 
For M Square Associates, LLC, net cash flows of this entity will be distributed to the partners as follows: (1) member loans 
and accrued interest; (2) our preferred return and capital contributions used to fund infrastructure costs; (3) the partners’ 
preferred returns and capital contributions used to fund all other costs, including the base land value credit, in proportion to 
the accrued returns and capital accounts; and (4) residual amounts distributed 50% to each member.
For Stevens Investors, LLC, net cash flows of this entity will be distributed to the partners as follows: (1) member loans 
and accrued interest; (2) pro rata return of the partners’ capital; (3) pro rata return of the partners’ respective unpaid 
preferred returns; and (4) varying splits of 85% to 60% to us and the balance to our partners as we reach specified return 
hurdles.  Our partners have the right to require us to acquire some or all of their interests for fair value for a defined period 
of time following the construction completion and stabilization (as defined in the operating agreement) of the joint 
venture’s office property; accordingly, we classify the fair value of our partners’ interest as redeemable noncontrolling 
interests in the mezzanine section of our consolidated balance sheet.  Our partners have the right to receive some or all of 
the consideration for the acquisition of their interests in the form of common units in COPLP.  

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

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

During the periods included herein, we also owned investments in the following consolidated real estate joint ventures:

•  Arundel Preserve #5, LLC, a joint venture owning property in Hanover, Maryland (in the Baltimore/Washington Corridor) 
and in which we had a 50% nominal ownership interest.  On September 17, 2013, we acquired our partner’s noncontrolling 
interest, along with incremental additional land value in the venture, in exchange for 221,501 common units in COPLP 
valued at $5.2 million;

•  MOR Forbes 2 LLC, a joint venture owning property in Lanham, Maryland (in the Baltimore/Washington Corridor) and in 

which we had a 50% nominal ownership interest.  On December 11, 2013, the joint venture sold the property, after which 
the proceeds were distributed to the partners and there was substantially no remaining business operations or property; and

•  COPT-FD Indian Head, LLC, a joint venture owning property in Charles County, Maryland (in our “Other” region).  On 
August 7, 2014, the joint venture’s property was repurchased by Charles County under the terms of a development 
agreement for $6.4 million, after which the proceeds were distributed to the partners and there was no remaining business 
operations or assets.

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

We consolidate the real estate joint ventures described above because we have: (1) the power to direct the matters that most 

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

Our commitments and contingencies pertaining to our real estate joint ventures are disclosed in Note 20.

Unconsolidated Real Estate Joint Venture

We had a 20% ownership interest in an unconsolidated real estate joint venture that operated 16 operating properties, and 
in which we had a negative investment balance of $6.4 million as of December 31, 2012.  We accounted for the investment in 
the joint venture using the equity method of accounting.  On December 6, 2013, the holder of mortgage debt encumbering all of 
the joint venture’s properties foreclosed on the properties.  As a result, title to the properties was transferred to the mortgage

investment in the joint venture in 2013 of $6.3 million, which is included in the line entitled “gain on sales of real estate, net of 
income taxes” on our consolidated statements of operations.

Our notes receivable from the City of Huntsville funded infrastructure costs in connection with our LW Redstone Company, 
LLC joint venture (see Note 6) and carry an interest rate of 9.95%.  These notes and the accrued and unpaid interest thereon, 
which is compounded annually on March 1st, will be repaid using the real estate taxes generated by the properties constructed 
by the joint venture.  When these tax revenues are sufficient to cover the debt service on a certain increment of municipal

thereon.  Each note has a maturity date of the earlier of 30 years from the date issued or the expiration of the tax increment

We did not have an allowance for credit losses in connection with our investing receivables as of December 31, 2015 or

We recognize a valuation allowance on our deferred tax asset if we believe 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 deferred tax asset valuation allowance is 
due to a decrease in future projected operating income in our TRS resulting primarily from our dispositions of certain properties 
to which the TRS provided amenity services and our planned reduction in amenity services provided by the TRS at certain other 
properties.  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, 2015 net deferred tax asset.

(1)  The carrying values of our loans other than the Revolving Credit Facility reflect net deferred financing costs of $8.0 million as of 

December 31, 2015 and $6.0 million as of December 31, 2014.

(2)   Several of the fixed rate mortgages carry interest rates that were above or below market rates upon assumption and therefore were 
recorded at their fair value based on applicable effective interest rates.  The carrying values of these loans reflect net unamortized 
premiums totaling $514,000 as of December 31, 2015 and $42,000 as of December 31, 2014.

(3)  The weighted average interest rate on our fixed rate mortgage loans was 6.08% as of December 31, 2015.
(4)   The weighted average interest rate on our variable rate secured loans was 2.2% as of December 31, 2015.
(5)  Refer to the paragraphs below for further disclosure. 
(6)   As discussed below, an additional $150.0 million in borrowings is available to be drawn under a term loan entered into in the current 

year.  In addition, we have the ability to borrow an additional $430.0 million in the aggregate under these term loan facilities, provided 
that there is no default under the facilities and subject to the approval of the lenders.    
(7)   The weighted average interest rate on these loans was 1.92% as of December 31, 2015.
(8)   The carrying value of these notes reflects an unamortized discount totaling $2.2 million as of December 31, 2015 and $2.5 million as of 

December 31, 2014.  The effective interest rate under the notes, including amortization of the issuance costs, was 3.70%.

(9)   The carrying value of these notes reflects an unamortized discount totaling $3.8 million as of December 31, 2015 and $4.2 million as of 

December 31, 2014.  The effective interest rate under the notes, including amortization of the issuance costs, was 5.49%.

(10) Refer to the paragraphs below for further disclosure.
(11)  These notes carry interest rates that were below market rates upon assumption and therefore were recorded at their fair value based on 

applicable effective interest rates.  The carrying value of these notes reflects an unamortized discount totaling $554,000 as of 
December 31, 2015 and $654,000 as of December 31, 2014.

(12) On April 20, 2015, we redeemed the remaining $575,000 principal amount of these notes at 100% of their principal amount.  The 

carrying value of these notes as of December 31, 2014 included an unamortized discount totaling $3,000. 

All debt is owed by the Operating Partnership.  While COPT is not directly obligated by any debt, it has guaranteed the 
Operating Partnership’s Revolving Credit Facility, Term Loan Facilities and Unsecured Senior Notes.

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.  In addition, the terms 
of some of COPLP’s debt may limit its ability to make certain types of payments and other distributions to COPT in the event 
of default or when such payments or distributions may prompt failure of debt covenants.  As of December 31, 2015, we were 
within the compliance requirements of these financial covenants.

On May 6, 2015, we entered into a credit agreement with a group of lenders for which KeyBanc Capital Markets and J.P. 

Morgan Securities LLC acted as joint lead arrangers and joint book runners, KeyBank National Association acted as 
administrative agent and JPMorgan Chase Bank, N.A. acted as syndication agent (the “Consolidated Credit Agreement”) to 
amend, restate and consolidate the terms of our existing unsecured revolving credit facility (the “Revolving Credit Facility”) 
and one of our term loan facilities discussed below.  The lenders’ aggregate commitment under the Revolving Credit Facility is 
$800.0 million, with the ability for us to increase the lenders’ aggregate commitment to $1.3 billion, provided that there is no 
default under the facility and subject to the approval of the lenders.  Amounts available under the facility are computed based 
on 60% of our unencumbered asset value, as defined in the agreement.  The facility matures on May 6, 2019, with the ability 
for us to further extend such maturity by two six-month periods at our option, provided that there is no default under the facility 
and we pay an extension fee of 0.075% of the total availability under the facility for each extension period.  The interest rate on 
the facility is based on LIBOR (customarily the 30-day rate) plus 0.875% to 1.600%, as determined by the credit ratings 
assigned to COPLP by Standard & Poor’s Rating Services, Moody’s Investor Services, Inc. or Fitch Ratings Ltd. (collectively, 
the “Ratings Agencies”).  The facility also carries a quarterly fee that is based on the lenders’ aggregate commitment under the 
facility multiplied by a per annum rate of 0.125% to 0.300%, as determined by the credit ratings assigned to COPLP by the 
Ratings Agencies.  As of December 31, 2015, the maximum borrowing capacity under this facility totaled $800.0 million, of 
which $741.7 million was available.

Weighted average borrowings under our Revolving Credit Facility totaled $125.0 million in 2015 and $15.9 million in 

2014.  The weighted average interest rate on our Revolving Credit Facility was 1.40% in 2015 and 1.47% in 2014.

Term Loan Facilities

Effective February 14, 2012, we entered into an unsecured term loan agreement under which we borrowed $250.0 million.  

In connection with our entry into the Consolidated Credit Agreement on May 6, 2015 discussed above, we increased the loan 
amount to $300.0 million, with a right for us to borrow up to an additional $200.0 million during the term for an aggregate 
maximum loan of $500.0 million, subject to certain conditions.  The term loan matures on May 6, 2020.  The variable interest 
rate on the loan is based on the LIBOR rate (customarily the 30-day rate) plus 0.90% to 1.85%, as determined by the credit 
ratings assigned to COPLP by the Ratings Agencies.

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

Effective August 3, 2012, we entered into an unsecured term loan agreement under which we borrowed $120.0 million, 
with the ability for us to borrow an additional $80.0 million, provided that there is no default under the loan and subject to the 
approval of the lenders.  The term loan matures on August 2, 2019.  The variable interest rate on the loan is based on the 
LIBOR rate (customarily the 30-day rate) plus 2.10% to 2.60%, as determined by our leverage levels.

Effective December 17, 2015, we entered into an unsecured term loan agreement with an initial commitment of $250.0 
million, of which we borrowed $100.0 million.  We have until September 2016 to draw the remaining initial commitment.  We 
also have the ability to borrow $150.0 million above the initial commitment, provided that there is no default under the loan and 
subject to the approval of the lenders.  The term loan matures on December 17, 2022.   The variable interest rate on the loan is 
based on the LIBOR rate (customarily the 30-day rate) plus 1.40% to 2.35%, as determined by our leverage levels.

We also had an unsecured term loan agreement under which we borrowed $400.0 million in 2011.  In 2013, we amended 

this term loan and repaid $150.0 million of the loan balance.  We repaid the loan balance by an additional $100.0 million in 
2014 and repaid the remaining balance in 2015.  

Unsecured Senior Notes

We issued the following senior notes in 2014 and 2015:

• 

• 

$300.0 million of 3.700% Senior Notes at an initial offering price of 99.739% of their face value on May 14, 2014, 
resulting in proceeds, after deducting underwriting discounts, but before other offering expenses, of $297.3 million.  The 
carrying value of these notes reflects an unamortized discount totaling $2.1 million as of December 31, 2015 and $2.4 
million as of December 31, 2014.  The effective interest rate under the notes, including amortization of the issuance costs, 
was 3.85%; and
$300.0 million of 5.000% Senior Notes at an initial offering price of 99.510% of their face value on June 29, 2015, 
resulting in proceeds, after deducting underwriting discounts, but before other offering expenses of $296.6 million.  The 
carrying value of these notes reflects an unamortized discount totaling $3.3 million at December 31, 2015.  The effective 
interest rate under the notes, including amortization of the issuance costs, was 5.15%. 

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

redemption price equal to the greater of (1) the aggregate principal amount of the notes being redeemed or (2) the sum of the 
present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such 
payments of interest accrued as of the date of redemption) discounted to its present value, on a semi-annual basis at an adjusted 
treasury rate plus a spread (30 basis points for the 3.600% Senior Notes, 40 basis points for the 5.250% Senior Notes, 25 basis 
points for the 3.700% Senior Notes and 45 basis points for the 5.000% Senior Notes), plus, in each case, accrued and unpaid 
interest thereon to the date of redemption.  However, in each case, if this redemption occurs on or after three months prior to the 
maturity date, the redemption price will be equal to 100% of the principal amount of the notes being redeemed, plus accrued 
and unpaid interest thereon to, but not including, the applicable redemption date.  These notes are unconditionally guaranteed 
by COPT.

Gains (Losses) on Early Extinguishment of Debt

Our gains (losses) on early extinguishment of debt in 2013, 2014 and 2015 included the following:

• 

• 

• 

a gain of $67.8 million on December 23, 2013 resulting from our transfer of title to properties to the lender on a $146.5 
million nonrecourse mortgage loan and being relieved of the debt obligation plus accrued interest as discussed further in 
Note 5;
a loss of $25.9 million in 2013 resulting from early repayment of $239.4 million principal amount of 4.25% Exchangeable 
Senior Notes;
a loss of $9.1 million in December 2014, when we completed the defeasance of, and full satisfaction of our obligations 
with respect to, (1) $103.0 million principal amount of secured nonrecourse mortgage loan due to mature on November 6, 
2015 and bearing an interest rate of 5.53% and (2) $108.5 million principal amount of secured nonrecourse mortgage loan

We have agreements with each of our interest rate derivative counterparties that contain provisions under which, if we 
default or are capable of being declared in default on defined levels of our indebtedness, we could also be declared in default on

our derivative obligations.  These agreements also incorporate the loan covenant provisions of our indebtedness with a lender 
affiliate of the derivative counterparties.  Failure to comply with the loan covenant provisions could result in our being declared 
in default on any derivative instrument obligations covered by the agreements.  As of December 31, 2015, the fair value of 
interest rate derivatives in a liability position related to these agreements was $3.2 million, excluding the effects of accrued 
interest and credit valuation adjustments.  As of December 31, 2015, we had not posted any collateral related to these 
agreements.  We are not in default with any of these provisions.  If we breached any of these provisions, we could be required 
to settle our obligations under the agreements at their termination value of $3.6 million.

Each series of preferred shares is nonvoting and redeemable for cash in the amount of its liquidation preference at COPT’s 
option on or after the earliest redemption date.  The Series K Cumulative Redeemable Preferred Shares are also convertible, 
subject to certain conditions, into common shares on the basis of 0.8163 common shares for each preferred share.  Holders of 
all preferred shares are entitled to cumulative dividends, payable quarterly (as and if declared by the Board of Trustees).  In the 
case of each series of preferred shares, there is a series of COPLP preferred units owned by COPT that carries substantially the 
same terms.

COPT redeemed all of the outstanding shares of its 7.500% Series H Preferred Shares on June 16, 2014 at a price of $25.00 

per share, or $50.0 million in the aggregate, plus accrued and unpaid dividends thereon through the date of redemption, and 
recognized a $1.8 million decrease to net income available to common shareholders pertaining to the shares’ original issuance 
costs incurred at the time of the redemption.

Common Shares

COPT completed the public offering of 5.52 million common shares in November 2014 at an offering price of $27.30 per 

share for net proceeds of $148.9 million after underwriter discounts but before offering expenses.  COPT contributed the net 
proceeds from this issuance to COPLP in exchange for an equal number of units in COPLP.

In October 2012, COPT established an at-the-market (“ATM”) stock offering program 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 $150.0 
million.  Through December 31, 2015, COPT issued the following common shares under the program:

• 

• 

1.5 million shares on July 15, 2013 at a weighted average price of $26.05 per share.  Net proceeds from the shares issued 
totaled $38.5 million, after payment of $0.6 million in commissions to sales agents; and
890,241 common shares issued in 2015 at a weighted average price of $30.29 per share.  Net proceeds from the shares 
issued totaled $26.6 million, after payment of $0.4 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.  
COPT’s remaining capacity under the ATM Plan is an aggregate gross sales price of $84.0 million in common share sales.

Holders of COPLP common units converted their units into COPT common shares on the basis of one common share for 

each common unit in the amount of 160,160 in 2015, 140,149 in 2014 and 311,343 in 2013.

COPT declared dividends per common share of $1.10 in 2015, 2014 and 2013.

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

In the case of each series of preferred units, COPT had preferred shares that carry substantially the same terms.  Each series of 
preferred units are redeemable for cash in the amount of its liquidation preference at our option on or after the earliest 
redemption date.  The Series K Preferred Units are also convertible, subject to certain conditions, into common units on the 
basis of 0.8163 common units for each preferred unit.  COPT, as holder of these preferred units, is entitled to cumulative 
distributions, payable quarterly (as and if declared by the Board of Trustees). 

COPLP redeemed all of the outstanding units of its 7.500% Series H Preferred Units held by COPT on June 16, 2014 at a 

price of $25.00 per unit, or $50.0 million in the aggregate, plus accrued and unpaid distributions thereon through the date of 
redemption, and recognized a $1.8 million decrease to net income available to common unitholders pertaining to the units’ 
original issuance costs at the time of the redemption.

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 (as described below), and may be 
redeemed for cash by COPLP at COPLP’s option any time after September 22, 2019.  The owner of these units is entitled to a 
priority annual cumulative return equal to 7.5% of their liquidation preference through September 22, 2019; the annual 
cumulative preferred return increases for each subsequent five-year period, subject to certain maximum limits.  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.

Common Units 

COPT owned 96.3% of COPLP’s common units as of December 31, 2015 and 96.0% as of December 31, 2014. 

COPT acquired additional common units through the public offering of 5.52 million common shares in November 2014 at 

an offering price of $27.30 per share for net proceeds of $148.9 million (after underwriter discounts but before offering 
expenses) that were contributed to COPLP in exchange for an equal number of common units in COPLP.

Through December 31, 2015, COPT issued the following common shares under the ATM program:

• 

• 

1.5 million common shares on July 15, 2013 at a weighted average price of $26.05 per share.  Net proceeds from the shares 
issued totaled $38.5 million, after payment of $0.6 million in commissions to sales agents; and
890,241 common shares in 2015 at a weighted average price of $30.29 per share; net proceeds from the shares issued 
totaled $26.6 million, after payment of $0.4 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. 

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).  Limited partners holding common units redeemed their units into common shares on the 
basis of one common share for each common unit in the amount of 160,160 in 2015, 140,149 in 2014 and 311,343 in 2013. 

We declared distributions per common unit of $1.10 in 2015, 2014 and 2013.

Share-Based Compensation and Other Compensation Matters

Share-Based Compensation Plans

In May 2010, COPT adopted the Amended and Restated 2008 Omnibus Equity and Incentive Plan.  COPT may issue 

equity-based awards under this plan to officers, employees, non-employee trustees and any other key persons of us and our 
subsidiaries, as defined in the plan.  The plan provides for a maximum of 5.9 million common shares in COPT to be issued in 
the form of options, share appreciation rights, deferred share awards, restricted share awards, unrestricted share awards, 
performance shares, dividend equivalent rights and other equity-based awards and for the granting of cash-based awards.  The 
plan expires on May 13, 2020.

In March 1998, COPT adopted a long-term incentive plan for our Trustees and employees.  This plan, which expired in 

March 2008, provided for the award of options, restricted shares and dividend equivalents.  

Awards under these plans to nonemployee Trustees generally vest on the first anniversary of the grant date provided that 

the Trustee remains in his or her position.  Awards granted to employees vest based on increments and over periods of time set 
forth under the terms of the respective awards provided that the employees remain employed by us.  Options expire ten years 
after the date of grant.  Shares for each of the share-based compensation plans are issued under registration statements on Form 
S-8 that became effective upon filing with the Securities and Exchange Commission.  In connection with awards of common 
shares granted by COPT under such share-based compensation plans, COPLP issues to COPT an equal number of equity 
instruments with identical terms.

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 Rank
75th or greater
50th or greater
25th
Below 25th

  Earned PSUs Payout %
  200% of PSUs granted

  0% of PSUs granted

F-45

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

If the percentile rank exceeds the 25th percentile and is between two of the percentile ranks set forth in the table above, then the 
percentage of the earned 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, in settlement of the award, will issue a number of 
fully-vested COPT common shares equal to the sum of:

• 
• 

the number of earned PSUs in settlement of the award plan; plus
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.

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 return relative to its peer group of companies:

• 
• 
• 

• 

for the 2011 PSUs that vested in 2014, there was no payout value in connection with the vesting; 
for the 2012 PSUs that vested in 2014, we issued 40,309 common shares in settlement of the PSUs on March 5, 2015; 
for 2013 and 2014 PSUs issued to Mr. Stephen E. Riffee, our former Chief Financial Officer who departed on February 3, 
2015, we issued 15,289 common shares on March 5, 2015 in settlement of such PSUs; and
for the 2013 PSUs that vested on December 31, 2015, there was no payout value in connection with the vesting.

We computed grant date fair values for PSUs using Monte Carlo models and are recognizing these values over three-year 

periods that commenced on the respective grant dates.  The grant date fair value and certain of the assumptions used in the 
Monte Carlo models for the PSUs granted in 2013, 2014 and 2015 are set forth below:

In 2015, nonemployee members of our Board of Trustees were granted a total of 24,056 deferred share awards with an 
aggregate grant date fair value of $642,000 ($26.70 per share).  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).  In 2015, we issued 15,485 common shares in settlement of deferred share awards granted in 2014; these shares had a 
grant date fair value of $26.77 per share, and the aggregate intrinsic value of the shares on the settlement date was $413,000.

We have not issued options since 2009, and all of our options were vested and fully expensed as of December 31, 2015.

Information by Business Segment

Effective in the quarter ended December 31, 2015, we changed the reportable segments that we use to review operating results and make decisions regarding segment 

performance and resource allocation.  Given the changes in our portfolio resulting from development, acquisition and disposition activities, we made this change to better align our 
segments with our business strategy by contemplating the market characteristics of our properties.  Our new segment reporting includes the following segments: Defense/IT 
Locations; Regional Office; our operating wholesale data center; and other.  Our segment reporting also includes reporting for Defense/IT Locations sub-segments, which include 
the following: Fort George G. Meade and the Baltimore/Washington Corridor (referred to herein as “Fort Meade/BW Corridor”); Northern Virginia Defense/IT Locations; 
Lackland Air Force Base (in San Antonio); locations serving the U.S. Navy ( “Navy Support Locations”), which included properties proximate to the Washington Navy Yard, the 
Naval Air Station Patuxent River in Maryland and the Naval Surface Warfare Center Dahlgren Division in Virginia); Redstone Arsenal (in Huntsville); Colorado Defense/IT 
Locations; 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).  The table below reports segment financial information for our reportable segments (in thousands).  We measure the performance of our segments through the 
measure we define as NOI from real estate operations, which is derived by subtracting property operating expenses from revenues from real estate operations.

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

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):

The accounting policies of the segments are the same as those used to prepare our consolidated financial statements, except 
that discontinued operations are not presented separately for segment purposes.  In the segment reporting presented above, we 
did not allocate interest expense, depreciation and amortization, impairment losses, loss on early extinguishment of debt and 
gain on sales of real estate to our real estate segments since they are not included in the measure of segment profit reviewed by 
management.  We also did not allocate general and administrative expenses, business development expenses and land carry 
costs, interest and other income, equity in income of unconsolidated entities, income taxes and noncontrolling interests because 
these items represent general corporate or non-operating property items not attributable to segments.

Discontinued Operations

Income from discontinued operations primarily includes revenues and expenses associated with the following:

• 
• 
• 
• 

920 Elkridge Landing Road in the Baltimore/Washington Corridor that was sold on June 25, 2013;
4230 Forbes Boulevard in the Baltimore/Washington Corridor that was sold on December 11, 2013;
15 operating properties in Colorado Springs that were sold on December 12, 2013; and
nine operating properties in the Baltimore/Washington Corridor and five operating properties in Colorado Springs for 
which the title to the properties was transferred to the mortgage lender on December 23, 2013.

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 COPT common shares were converted; and (2) the effect 
of dilutive potential common shares outstanding during the period attributable to share-based compensation using the 
treasury stock or if-converted methods; and
the numerator is adjusted to add back any changes in income or loss that would result from the assumed conversion into 
common shares that we added to the denominator.

The following share-based compensation securities were excluded from the computation of diluted EPS because their effect 
was antidilutive:

•  weighted average restricted shares and deferred share awards of 410,000 for 2015, 401,000 for 2014 and 385,000 for 2013; 

and

•  weighted average options of 469,000 for 2015, 492,000 for 2014 and 636,000 for 2013, respectively.

As discussed in Note 10, we had outstanding senior notes with an exchange settlement feature, but such notes did not affect 
our diluted EPS reported above since the weighted average closing price of COPT’s common shares during each of the periods 
was less than the exchange prices per common share applicable for such periods.

We present both basic and diluted EPU.  We compute basic EPU by dividing net income available to common unitholders

• 

• 

the denominator is increased to include: (1) the weighted average number of potential additional common units that would

Commitments and Contingencies

Litigation

In the normal course of business, we are involved in legal actions arising from our ownership and administration of 
properties.  We establish reserves for specific legal proceedings when we determine that the likelihood of an unfavorable 
outcome is probable and the amount of loss can be reasonably estimated.  Management does not anticipate that any liabilities 
that may result from such proceedings will have a materially adverse effect on our financial position, operations or liquidity.  
Our assessment of the potential outcomes of these matters involves significant judgment and is subject to change based on 
future developments.

Environmental

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

Tax Incremental Financing Obligation

In August 2010, Anne Arundel County, Maryland issued $30 million in tax incremental financing bonds to third-party 
investors in order to finance public improvements needed in connection with our project known as National Business Park 
North.  The real estate taxes on increases in assessed value of a development district encompassing National Business Park 
North are to be transferred to a special fund pledged to the repayment of the bonds.  We recognized a $1.9 million liability 
through December 31, 2015 representing our estimated obligation to fund through a special tax any future shortfalls between 
debt service on the bonds and real estate taxes available to repay the bonds.

Operating Leases

We are obligated as lessee under operating leases (mostly ground leases) with various expiration dates extending to the 
year 2100.  Future minimum rental payments due under the terms of these operating leases as of December 31, 2015 follow (in 
thousands):

Environmental Indemnity Agreement

In connection with a lease and subsequent sale in 2008 and 2010 of three properties in Dayton, New Jersey, we agreed to 
provide certain environmental indemnifications.  The prior owner of the properties, a Fortune 100 company that is responsible 
for groundwater contamination at such properties, previously agreed to indemnify us for (1) direct losses incurred in connection 
with the contamination and (2) its failure to perform remediation activities required by the State of New Jersey, up to the point 
that the state declares the remediation to be complete.  Under the environmental indemnification agreement, we agreed to the 
following:

• 

• 

• 

to indemnify the tenant against losses covered under the prior owner’s indemnity agreement if the prior owner fails to 
indemnify the tenant for such losses.  This indemnification is capped at $5.0 million in perpetuity after the State of New 
Jersey declares the remediation to be complete;
to indemnify the tenant for consequential damages (e.g., business interruption) at one of the buildings in perpetuity and 
another of the buildings through 2025.  This indemnification is limited to $12.5 million; and
to pay 50% of additional costs related to construction and environmental regulatory activities incurred by the tenant as a 
result of the indemnified environmental condition of the properties.  This indemnification is limited to $300,000 annually 
and $1.5 million in the aggregate.

21. 

Subsequent Event

On February 10, 2016, our Board of Trustees appointed Stephen E. Budorick, our Executive Vice President and Chief 
Operating Officer since September 2011, to become our President and Chief Executive Officer effective May 12, 2016, the date 
of the Company’s 2016 Annual Meeting of Shareholders.  On that date, Roger A. Waesche, Jr., our current President and Chief 
Executive Officer, will leave the Company to pursue other interests and he will not be nominated for reelection as a Trustee.  
The Board expects to appoint Mr. Budorick to our Board of Trustees after the 2016 Annual Meeting of Shareholders.  In 
connection with the departure of Mr. Waesche, we will recognize executive transition costs of approximately $2.9 million in 
2016.
