Notes to Consolidated Financial Statements
(unaudited)
1. Organization
Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company”, “we” or “us”) is a fully-integrated and self-managed real estate investment trust (“REIT”). We own, manage, lease, develop and selectively acquire office and data center properties. The majority of our portfolio is in locations that support the United States Government (“USG”) and its contractors, most of whom are engaged in national security, defense and information technology (“IT”) related activities servicing what we believe are growing, durable, priority missions (“Defense/IT Locations”). We also own a portfolio of office properties located in select urban/urban-like submarkets in the Greater Washington, DC/Baltimore region with durable Class-A office fundamentals and characteristics (“Regional Office”). As of March 31, 2022, our properties included the following:
•188 properties totaling 22.0 million square feet comprised of 17.0 million square feet in 161 office properties and 5.0 million square feet in 27 single-tenant data center shells. We owned 19 of these data center shells through unconsolidated real estate joint ventures;
•11 properties under development (eight office properties and three data center shells), including two partially-operational properties, that we estimate will total approximately 1.7 million square feet upon completion; and
•approximately 710 acres of land controlled for future development that we believe could be developed into approximately 8.7 million square feet and 43 acres of other land.
We conduct almost all of our operations and own almost all of our assets through our operating partnership, Corporate Office Properties, L.P. (“COPLP”) and subsidiaries (collectively, the “Operating Partnership”), of which COPT is the sole general partner. COPLP owns real estate directly and through subsidiary partnerships and limited liability companies (“LLCs”). In addition to owning real estate, COPLP also owns subsidiaries that provide real estate services such as property management, development and construction services primarily for our properties but also for third parties. Some of these services are performed by a taxable REIT subsidiary (“TRS”).
Equity interests in COPLP are in the form of common and preferred units. As of March 31, 2022, COPT owned 98.0% of the outstanding COPLP common units (“common units”) and there were no preferred units outstanding. Common units not owned by COPT carry certain redemption rights. The number of common units owned by COPT is equivalent to the number of outstanding common shares of beneficial interest (“common shares”) of COPT, and the entitlement of common units to quarterly distributions and payments in liquidation is substantially the same as that of COPT common shareholders.
COPT’s common shares are publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “OFC”.
2. Summary of Significant Accounting Policies
Basis of Presentation
These 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. We also consolidate certain entities when control of such entities can be achieved through means other than voting rights (“variable interest entities” or “VIEs”) if we are deemed to be the primary beneficiary of such entities. We eliminate all intercompany balances and transactions in consolidation.
We use the equity method of accounting when we own an interest in an entity and can exert significant influence over but cannot control the entity’s operations. We discontinue equity method accounting if our investment in an entity (and net advances) is reduced to zero unless we have guaranteed obligations of the entity or are otherwise committed to provide further financial support for the entity.
When we own an equity investment in an entity and cannot exert significant influence over its operations, we measure the investment at fair value, with changes recognized through net income. For an investment without a readily determinable fair value, we measure the investment at cost, less any impairments, plus or minus changes resulting from observable price changes for an identical or similar investment of the same issuer.
These interim financial statements should be read together with the consolidated financial statements and notes thereto as of and for the year ended December 31, 2021 included in our 2021 Annual Report on Form 10-K. The unaudited consolidated financial statements include all adjustments that are necessary, in the opinion of management, to fairly state our financial position and results of operations. All adjustments are of a normal recurring nature. The consolidated financial statements have been prepared using the accounting policies described in our 2021 Annual Report on Form 10-K as updated for our adoption of recent accounting pronouncements discussed below.
9

Reclassifications
We reclassified certain amounts from prior periods to conform to the current period presentation of our consolidated financial statements with no effect on previously reported net income or equity, including amounts reclassified in conjunction with the transfer of a wholesale data center to discontinued operations in the fourth quarter of 2021. We provide disclosure regarding our discontinued operations in Note 4.
Recent Accounting Pronouncements
In March 2020, the Financial Accounting Standards Board issued guidance containing practical expedients for reference rate reform related activities pertaining to debt, leases, derivatives and other contracts. The guidance is optional and may be elected over time as reference rate reform activities occur. In 2020, we elected to apply an expedient to treat any changes in loans resulting from reference rate reform as debt modifications (as opposed to extinguishments) and hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of the hedge accounting expedients preserves the presentation of derivatives consistent with past presentation. We will continue to evaluate the impact of this guidance and may apply other elections as applicable as additional changes in the market occur.
3. Fair Value Measurements
Recurring Fair Value Measurements
We have a non-qualified elective deferred compensation plan for Trustees and certain members of our management team that, prior to December 31, 2019, permitted participants to defer up to 100% of their compensation on a pre-tax basis and receive a tax-deferred return on such deferrals. Effective December 31, 2019, no new investments of deferred compensation were eligible for the plan. The assets held in the plan (comprised primarily of mutual funds and equity securities) and the corresponding liability to the participants are measured at fair value on a recurring basis on our consolidated balance sheets using quoted market prices, as are other marketable securities that we hold. The balance of the plan, which was fully funded and totaled $2.3 million as of March 31, 2022, is included in the line entitled “prepaid expenses and other assets, net” on our consolidated balance sheets along with an insignificant amount of other marketable securities. The offsetting liability associated with the plan is adjusted to fair value at the end of each accounting period based on the fair value of the plan assets and reported in “other liabilities” on our consolidated balance sheets. The assets of the plan are classified in Level 1 of the fair value hierarchy, while the offsetting liability is classified in Level 2 of the fair value hierarchy.
The fair values of our interest rate derivatives are determined using widely accepted valuation techniques, including a discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate market data and implied volatilities in such interest rates. While we determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our interest rate derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default. However, as of March 31, 2022, we assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivatives and determined that these adjustments were not significant. As a result, we determined that our interest rate derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.
The carrying values of cash and cash equivalents, restricted cash, accounts receivable, other assets (excluding investing receivables) and accounts payable and accrued expenses are reasonable estimates of their fair values because of the short maturities of these instruments. The fair values of our investing receivables, as disclosed in Note 7, were based on the discounted estimated future cash flows of the loans (categorized within Level 3 of the fair value hierarchy); the discount rates used approximate current market rates for loans with similar maturities and credit quality, and the estimated cash payments include scheduled principal and interest payments. For our disclosure of debt fair values in Note 9, we estimated the fair value of our unsecured senior notes based on quoted market rates for our senior notes (categorized within Level 1 of the fair value hierarchy) and estimated the fair value of our other debt based on the discounted estimated future cash payments to be made on such debt (categorized within Level 3 of the fair value hierarchy); the discount rates used approximate current market rates for loans, or groups of loans, with similar maturities and credit quality, and the estimated future payments include scheduled principal and interest payments. Fair value estimates are made as of a specific point in time, are subjective in nature and involve uncertainties and matters of significant judgment.
For additional fair value information, refer to Note 7 for investing receivables, Note 9 for debt and Note 10 for interest rate derivatives.

The table below presents the effect of our interest rate derivatives on our consolidated statements of operations and comprehensive income (in thousands):

|  |  |  |  | Amount of Income Recognized in AOCL on Derivatives |  |  |  |  | Amount of Loss Reclassified from AOCL into Interest Expense on Statement of Operations
Derivatives in Hedging Relationships |  |  |  | For the Three Months Ended March 31, |  |  |  | For the Three Months Ended March 31,

Based on the fair value of our derivatives as of March 31, 2022, we estimate that approximately $804,000 of losses will be reclassified from AOCL as an increase to interest expense over the next 12 months.
We have agreements with each of our interest rate derivative counterparties that contain provisions under which, if we default or are capable of being declared in default on defined levels of our indebtedness, we could also be declared in default on our derivative obligations. Failure to comply with the loan covenant provisions could result in our being declared in default on any derivative instrument obligations covered by the agreements. As of March 31, 2022, we were not in default with any of these provisions. As of March 31, 2022, the fair value of interest rate derivatives in a liability position related to these agreements was $665,000, excluding the effects of accrued interest and credit valuation adjustments. As of March 31, 2022, we had not posted any collateral related to these agreements. If we breach any of these provisions, we could be required to settle our obligations under the agreements at their termination value, which was $952,000 as of March 31, 2022.
11. Redeemable Noncontrolling Interests
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 sheets. The table below sets forth the activity for these redeemable noncontrolling interests (in thousands):

|  | For the Three Months Ended March 31,
|  | 2022 |  | 2021
Beginning balance |  | $ | 26,898 |  |  | $ | 25,430 |
Distributions to noncontrolling interests |  | (606) |  |  | (399) |
Net income attributable to noncontrolling interests |  | 567 |  |  | 412 |
Adjustment to arrive at fair value of interests |  | (39) |  |  | 482 |
Ending balance |  | $ | 26,820 |  |  | $ | 25,925 |

We determine the fair value of the interests based on unobservable inputs after considering the assumptions that market participants would make in pricing the interest. We apply a discount rate to the estimated future cash flows allocable to our partners from the properties underlying the respective joint ventures. Estimated cash flows used in such analyses are based on our plans for the properties and our views of market and economic conditions, and consider items such as current and future rental rates, occupancy projections and estimated operating and development expenditures.
12. Equity
As of March 31, 2022, we had remaining capacity under our at-the-market stock offering program equal to an aggregate gross sales price of $300 million in common share sales.
We declared dividends per common share of $0.275 in the three months ended March 31, 2022 and 2021.

Our investment grade credit risk classification represents entities with investment grade credit ratings from ratings agencies (such as Standard & Poor’s Ratings Services, Moody’s Investors Service, Inc. or Fitch Ratings Ltd.), meaning that they are considered to have at least an adequate capacity to meet their financial commitments, with credit risk ranging from minimal to moderate. Our non-investment grade credit risk classification represents entities with either no credit agency credit ratings or ratings deemed to be sub-investment grade; we believe that there is significantly more credit risk associated with this classification. The credit risk classifications of our investing receivables and tenant notes receivable were last updated in March 2022.
An insignificant portion of the investing and tenant notes receivables set forth above was past due, which we define as being delinquent by more than three months from the due date.
Notes receivable on nonaccrual status as of March 31, 2022 and December 31, 2021 were not significant. We did not recognize any interest income on notes receivable on nonaccrual status during the three months ended March 31, 2022 and 2021.

14. Information by Business Segment
We have the following reportable segments: Defense/IT Locations; Regional Office; Wholesale Data Center (the only property in which we sold on January 25, 2022); and Other. We also report on Defense/IT Locations sub-segments, which include the following: Fort George G. Meade and the Baltimore/Washington Corridor (“Fort Meade/BW Corridor”); Northern Virginia Defense/IT Locations (“NoVA Defense/IT”); Lackland Air Force Base (in San Antonio); locations serving the U.S. Navy (“Navy Support”), which included properties proximate to the Washington Navy Yard, the Naval Air Station Patuxent River in Maryland and the Naval Surface Warfare Center Dahlgren Division in Virginia; Redstone Arsenal (in Huntsville); and data center shells (properties leased to tenants to be operated as data centers in which the tenants fund the costs for the power, fiber connectivity and data center infrastructure). Our segment reporting included below reflects our retrospective reclassification of: certain activities to our Other reportable segment from our Wholesale Data Center reportable segment in the fourth quarter of 2021; and two properties to our NoVA Defense/IT sub-segment from our Regional Office segment in the first quarter of 2022.
We measure the performance of our segments through the measure we define as net operating income from real estate operations (“NOI from real estate operations”), which includes: real estate revenues and property operating expenses; and the net of revenues and property operating expenses of real estate operations owned through unconsolidated real estate joint ventures (“UJVs”) that is allocable to our ownership interest (“UJV NOI allocable to COPT”). Amounts reported for segment assets represent long-lived assets associated with consolidated operating properties (including the carrying value of properties, right-of-use assets, net of related lease liabilities, intangible assets, deferred leasing costs, deferred rents receivable and lease incentives) and the carrying value of investments in UJVs owning operating properties. Amounts reported as additions to long-lived assets represent additions to existing consolidated operating properties, excluding transfers from non-operating properties, which we report separately.

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

|  |  | For the Three Months Ended March 31,
|  |  |  |  | 2022 |  | 2021
Construction contract and other service revenues |  |  |  |  | $ | 53,200 |  |  | $ | 16,558 |

The following table reconciles our segment assets to our consolidated total assets (in thousands):

Total consolidated assets |  | $ | 4,132,026 |  |  | $ | 4,112,948 |

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, gain on sales of real estate, loss on early extinguishment of debt and equity in income of unconsolidated entities not included in NOI to our real estate segments since they are not included in the measure of segment profit reviewed by management. We also did not allocate general, administrative and leasing expenses, business development expenses and land carry costs, interest and other income, credit loss (expense) recoveries, income taxes and noncontrolling interests because these items represent general corporate or non-operating property items not attributable to segments.
15. Construction Contract and Other Service Revenues
We disaggregate our construction contract and other service revenues by compensation arrangement and by service type as we believe it best depicts the nature, timing and uncertainty of our revenue. The table below reports construction contract and other service revenues by compensation arrangement (in thousands):

Contract assets, which we refer to herein as construction contract costs in excess of billings, net, are included in prepaid expenses and other assets, net on our consolidated balance sheets. The beginning and ending balances of our contract assets were as follows (in thousands):

| For the Three Months Ended March 31,
| 2022 |  | 2021
Beginning balance | $ | 22,384 |  |  | $ | 10,343 |

Revenue allocated to the remaining performance obligations under existing contracts as of March 31, 2022 that will be recognized as revenue in future periods was $98.9 million, of which we expect to recognize approximately $84 million in the nine months ending December 31, 2022 and most of the remainder in 2023.
We have no deferred incremental costs incurred to obtain or fulfill our construction contracts or other service revenues as of March 31, 2022 and December 31, 2021. We had credit loss recoveries on construction contracts receivable and unbilled construction revenue of $372,000 in the three months ended March 31, 2022 and $141,000 in the three months ended March 31, 2021.
16. Share-Based Compensation
Restricted Shares
During the three months ended March 31, 2022, certain employees were granted a total of 142,411 restricted common shares with an aggregate grant date fair value of $3.8 million ($26.57 per share). Restricted shares granted to employees vest based on increments and over periods of time set forth under the terms of the respective awards provided that the employee remains employed by us. During the three months ended March 31, 2022, forfeiture restrictions lapsed on 120,753 previously issued common shares; these shares had a weighted average grant date fair value of $26.06 per share, and the aggregate intrinsic value of the shares on the vesting dates was $3.2 million.
24

Profit Interest Units in COPLP (“PIUs”)
We granted two forms of PIUs: time-based PIUs (“TB-PIUs”); and performance-based PIUs (“PB-PIUs”). TB-PIUs are subject to forfeiture restrictions until the end of the requisite service period, at which time the TB-PIUs automatically convert into vested PIUs. PB-PIUs are subject to a market condition in that the number of earned awards are determined at the end of the performance period (as described further below) and then settled in vested PIUs. Vested PIUs carry substantially the same rights to redemption and distributions as non-PIU common units.
TB-PIUs
During the three months ended March 31, 2022, we granted 86,202 TB-PIUs with an aggregate grant date fair value of $2.3 million ($26.57 per TB-PIU) to senior management team members. TB-PIUs granted to senior management team members vest based on increments and over periods of time set forth under the terms of the respective awards provided that the employee remains employed by us. Prior to vesting, TB-PIUs carry substantially the same rights to distributions as non-PIU common units but carry no redemption rights. During the three months ended March 31, 2022, forfeiture restrictions lapsed on 59,392 previously issued TB-PIUs; these TB-PIUs had a weighted average grant date fair value of $25.75 per unit, and the aggregate intrinsic value of the TB-PIUs on the vesting date was $1.6 million.
PB-PIUs
On January 1, 2022, we granted certain senior management team members 231,838 PB-PIUs with a three-year performance period concluding on the earlier of December 31, 2024 or the date of: (1) termination by us without cause, death or disability of the employee or constructive discharge of the employee (collectively, “qualified termination”); or (2) a sale event. The number of earned awards at the end of the performance period will be determined based on the percentile rank of COPT’s total shareholder return (“TSR”) relative to a peer group of companies, as set forth in the following schedule:

Percentile Rank |  | Earned PB-PIUs Payout %
75th or greater |  | 100% of PB-PIUs granted
50th (target) |  | 50% of PB-PIUs granted
25th |  | 25% of PB-PIUs granted
Below 25th |  | 0% of PB-PIUs granted

If the percentile rank exceeds the 25th percentile and is between two of the percentile ranks set forth in the table above, then the percentage of the earned awards will be interpolated between the ranges set forth in the table above to reflect any performance between the listed percentiles. If COPT’s TSR during the measurement period is negative, the maximum number of earned awards will be limited to the target level payout percentage. During the performance period, PB-PIUs carry rights to distributions equal to 10% of the distribution rights of non-PIU common units but carry no redemption rights.
At the end of the performance period, we will settle the award by issuing vested PIUs equal to: the number of earned awards; and the excess, if any, of (1) the aggregate distributions that would have been paid with respect to vested PIUs issued in settlement of the earned awards through the date of settlement had such vested PIUs been issued on the grant date over (2) the aggregate distributions made on the PB-PIUs during the performance period, divided by the price of our common shares on the settlement date. If a performance period ends due to a sale event or qualified termination, the number of earned awards is prorated based on the portion of the three-year performance period that has elapsed. If employment is terminated by the employee or by us for cause, all PB-PIUs are forfeited.
These PB-PIU grants had an aggregate grant date fair value of $3.8 million ($32.87 per target-level award associated with the grants) which is being recognized over the performance period. The grant date fair value was computed using a Monte Carlo model that included the following assumptions: baseline common share value of $27.97; expected volatility for common shares of 31.7%; and a risk-free interest rate of 0.98%.
Based on COPT’s TSR relative to its peer group of companies, for the 2019 PB-PIUs issued to executives that vested on December 31, 2021, we issued 156,104 PIUs in settlement of the PB-PIUs on February 1, 2022.
17. Earnings Per Share (“EPS”)
We present both basic and diluted EPS. We compute basic EPS by dividing net income available to common shareholders allocable to unrestricted common shares under the two-class method by the weighted average number of unrestricted common shares outstanding during the period. Our computation of diluted EPS is similar except that:
•the denominator is increased to include: (1) the weighted average number of potential additional common shares that would have been outstanding if securities that are convertible into common shares were converted; and (2) the effect of dilutive
25

potential common shares outstanding during the period attributable to redeemable noncontrolling interests and share-based compensation awards using the if-converted or treasury stock methods; and
•the numerator is adjusted to add back any changes in income or loss that would result from the assumed conversion into common shares that we add to the denominator.
Summaries of the numerator and denominator for purposes of basic and diluted EPS calculations are set forth below (in thousands, except per share data):

18. Commitments and Contingencies
Litigation and Claims
In the normal course of business, we are subject to legal actions and other claims. We record losses for specific legal proceedings and claims when we determine that a loss is probable and the amount of loss can be reasonably estimated. As of March 31, 2022, management believes that it is reasonably possible that we could recognize a loss of up to $3.7 million for certain municipal tax claims; while we do not believe this loss would materially affect our financial position or liquidity, it could be material to our results of operations. Management believes that it is also reasonably possible that we could incur losses pursuant to other claims but do not believe such losses would materially affect our financial position, liquidity or results of operations. Our assessment of the potential outcomes of these matters involves significant judgment and is subject to change based on future developments.
Environmental
We are subject to various Federal, state and local environmental regulations related to our property ownership and operation. We have performed environmental assessments of our properties, the results of which have not revealed any environmental liability that we believe would have a materially adverse effect on our financial position, operations or liquidity.
In connection with a lease and subsequent sale in 2008 and 2010 of three properties in Dayton, New Jersey, we agreed to provide certain environmental indemnifications limited to $19 million in the aggregate. We have insurance coverage in place to mitigate much of any potential future losses that may result from these indemnification agreements.
Tax Incremental Financing Obligation
Anne Arundel County, Maryland issued tax incremental financing bonds to third-party investors in order to finance public improvements needed in connection with our project known as the National Business Park. These bonds had a remaining principal balance of approximately $31 million as of March 31, 2022. The real estate taxes on increases in assessed values post-bond issuance of properties in development districts encompassing the National Business Park are transferred to a special fund pledged to the repayment of the bonds. While we are obligated to fund, through a special tax, any future shortfalls between debt service of the bonds and real estate taxes available to repay the bonds, as of March 31, 2022, we do not expect any such future fundings will be required.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Overview
During the three months ended March 31, 2022, we:
•finished the period with our portfolio 92.0% occupied and 93.9% leased;
•placed into service 283,000 square feet in two newly-developed properties that were 100.0% leased as of March 31, 2022; and
•sold our wholesale data center for $222.5 million, resulting in a gain on sale of $28.6 million. We used the proceeds to repay a portion of of our Term Loan Facility and the remainder to repay borrowings under our Revolving Credit Facility.
With regard to our operating portfolio square footage, occupancy and leasing statistics included below and elsewhere in this Quarterly Report on Form 10-Q, amounts disclosed include information pertaining to properties owned through unconsolidated real estate joint ventures.
We discuss significant factors contributing to changes in our net income in the section below entitled “Results of Operations.” In addition, the section below entitled “Liquidity and Capital Resources” includes discussions of, among other things:
•how we expect to generate and obtain cash for short and long-term capital needs; and
•material cash requirements for known contractual and other obligations.
You should refer to our consolidated financial statements and the notes thereto 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. 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, construction costs 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 reduced or delayed demand for additional space by our strategic customers;
•our ability to borrow on favorable terms;
•risks of property 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;
•risks and uncertainties regarding the impact of the COVID-19 pandemic, and similar pandemics, along with restrictive measures instituted to prevent spread, on our business, the real estate industry and national, regional and local economic conditions;
•our ability to satisfy and operate effectively under federal income tax rules relating to real estate investment trusts and partnerships;
•possible adverse changes in tax laws;
•the dilutive effects of issuing additional common shares;
•our ability to achieve projected results;
•security breaches relating to cyber attacks, cyber intrusions or other factors; and
•environmental requirements.
We undertake no obligation to publicly update or supplement forward-looking statements.

(1)Includes lease terminations and space reductions occurring in connection with lease renewals.
During the three months ended March 31, 2022, we leased 871,000 square feet, including: 448,000 square feet of renewal leasing, representing a tenant retention rate of 64.0%; 157,000 square feet of vacant space leasing; and 265,000 square feet of development leasing.
Annualized rental revenue is a measure that we use to evaluate the source of our rental revenue as of a point in time. It is computed by multiplying by 12 the sum of monthly contractual base rents and estimated monthly expense reimbursements under active leases as of a point in time (ignoring free rent then in effect and rent associated with tenant funded landlord assets). Our computation of annualized rental revenue excludes the effect of lease incentives. We consider annualized rental revenue to be a useful measure for analyzing revenue sources because, since it is point-in-time based, it does not contain increases and decreases in revenue associated with periods in which lease terms were not in effect; historical revenue under generally accepted accounting principles in the United States of America (“GAAP”) does contain such fluctuations. We find the measure particularly useful for leasing, tenant, segment and industry analysis. Tenant retention rate is a measure we use that represents the percentage of square feet renewed in a period relative to the total square feet scheduled to expire in that period; we include the effect of early renewals in this measure.
Results of Operations
We evaluate the operating performance of our properties using NOI from real estate operations, our segment performance measure, which includes real estate revenues and property operating expenses from continuing and discontinued operations and UJV NOI allocable to COPT. We view our NOI from real estate operations as comprising the following primary categories:
•office and data center shell properties:
•stably owned and 100% operational throughout the current and prior year reporting periods being compared. We define these as changes from “Same Properties”;
•developed or redeveloped and placed into service that were not 100% operational throughout the current and prior year reporting periods; and
•disposed; and
•our wholesale data center that we sold on January 25, 2022.
29

In addition to owning properties, we provide construction management and other services. The primary manner in which we evaluate the operating performance of our construction management and other service activities is through a measure we define as NOI from service operations, which is based on the net of the revenues and expenses from these activities. The revenues and expenses from these activities consist primarily of subcontracted costs that are reimbursed to us by customers along with a management fee. The operating margins from these activities are small relative to the revenue. We believe NOI from service operations is a useful measure in assessing both our level of activity and our profitability in conducting such operations.
Since both of the measures discussed above exclude certain items includable in net income, reliance on these measures has limitations; management compensates for these limitations by using the measures simply as supplemental measures that are considered alongside other GAAP and non-GAAP measures. A reconciliation of NOI from real estate operations and NOI from service operations to income from continuing operations reported on the consolidated statements of operations is provided in Note 14 to our consolidated financial statements.

Our Same Properties pool consisted of 176 properties, comprising 92.4% of our portfolio’s square footage as of March 31, 2022. This pool of properties changed from the pool used for purposes of comparing 2021 and 2020 in our 2021 Annual Report on Form 10-K due to the addition of nine properties placed in service and 100% operational on or before January 1, 2021 and eight properties owned through an unconsolidated real estate joint venture that was formed in 2020.

Regarding the changes in NOI from real estate operations reported above:
•developed and redeveloped properties placed in service reflects the effect of 10 properties placed in service in 2021 and 2022; and
•dispositions, net of retained interest in newly-formed UJVs reflects the effect of our sale of a 90% interest in two data center shells in 2021.
NOI from Service Operations

|  | For the Three Months Ended March 31,
|  | 2022 |  | 2021 |  | Variance
|  | (in thousands)
Construction contract and other service revenues |  | $ | 53,200 |  |  | $ | 16,558 |  |  | $ | 36,642 |
Construction contract and other service expenses |  | (51,650) |  |  | (15,793) |  |  | (35,857) |
NOI from service operations |  | $ | 1,550 |  |  | $ | 765 |  |  | $ | 785 |

Construction contract and other service revenues 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 an insignificant amount of income relative to our real estate operations.
Interest expense
Interest expense decreased due to lower weighted average interest rates in the current period resulting primarily from debt refinancings that we completed in 2021.
Loss on extinguishment of debt
The loss on early extinguishment of debt recognized in the prior period was attributable to our purchase of unsecured senior notes pursuant to tender offers.
Discontinued operations
Discontinued operations includes our wholesale data center, which we sold on January 25, 2022.
Funds from Operations
Funds from operations (“FFO”) is defined as net income computed using GAAP, excluding gains on sales and impairment losses of real estate (net of associated income tax) and real estate-related depreciation and amortization. FFO also includes adjustments to net income for the effects of the items noted above pertaining to UJVs that were allocable to our ownership interest in the UJVs. We believe that we use the National Association of Real Estate Investment Trusts (“Nareit”) definition of FFO, although others may interpret the definition differently and, accordingly, our presentation of FFO may differ from those of other REITs. We believe that FFO is useful to management and investors as a supplemental measure of operating performance because, by excluding gains on sales and impairment losses of real estate and investments in unconsolidated real estate joint ventures (net of associated income tax), and real estate-related depreciation and amortization, FFO can help one compare our operating performance between periods. In addition, since most equity REITs provide FFO information to the investment community, we believe that FFO is useful to investors as a supplemental measure for comparing our results to those of other equity REITs. We believe that net income is the most directly comparable GAAP measure to FFO.
Since FFO excludes certain items includable in net income, reliance on the measure has limitations; management compensates for these limitations by using the measure simply as a supplemental measure that is weighed in balance with other GAAP and non-GAAP measures. FFO is not necessarily an indication of our cash flow available to fund cash needs. Additionally, it should not be used as an alternative to net income when evaluating our financial performance or to cash flow from operating, investing and financing activities when evaluating our liquidity or ability to make cash distributions or pay debt service.
Basic FFO available to common share and common unit holders (“Basic FFO”) is FFO adjusted to subtract (1) preferred share dividends, (2) income attributable to noncontrolling interests through ownership of preferred units in the Operating Partnership or interests in other consolidated entities not owned by us, (3) depreciation and amortization allocable to noncontrolling interests in other consolidated entities and (4) Basic FFO allocable to share-based compensation awards. With these adjustments, Basic FFO represents FFO available to common shareholders and common unitholders. Common units in the Operating Partnership are substantially similar to our common shares and are exchangeable into common shares, subject to certain conditions. We believe that Basic FFO is useful to investors due to the close correlation of common units to common shares. We believe that net income is the most directly comparable GAAP measure to Basic FFO. Basic FFO has essentially
32

the same limitations as FFO; management compensates for these limitations in essentially the same manner as described above for FFO.
Diluted FFO available to common share and common unit holders (“Diluted FFO”) is Basic FFO adjusted to add back any changes in Basic FFO that would result from the assumed conversion of securities that are convertible or exchangeable into common shares. We believe that Diluted FFO is useful to investors because it is the numerator used to compute Diluted FFO per share, discussed below. We believe that net income is the most directly comparable GAAP measure to Diluted FFO. Since Diluted FFO excludes certain items includable in the numerator to diluted EPS, reliance on the measure has limitations; management compensates for these limitations by using the measure simply as a supplemental measure that is weighed in the balance with other GAAP and non-GAAP measures. Diluted FFO is not necessarily an indication of our cash flow available to fund cash needs. Additionally, it should not be used as an alternative to net income when evaluating our financial performance or to cash flow from operating, investing and financing activities when evaluating our liquidity or ability to make cash distributions or pay debt service.
Diluted FFO available to common share and common unit holders, as adjusted for comparability is defined as Diluted FFO adjusted to exclude: operating property acquisition costs; gain or loss on early extinguishment of debt; FFO associated with properties securing non-recourse debt on which we have defaulted and which we have extinguished, or expect to extinguish, via conveyance of such properties, including property NOI, interest expense and gains on debt extinguishment (discussed further below); loss on interest rate derivatives; demolition costs on redevelopment and nonrecurring improvements; executive transition costs; issuance costs associated with redeemed preferred shares; allocations of FFO to holders of noncontrolling interests resulting from capital events; and certain other expenses that we believe are not closely correlated with our operating performance. This measure also includes adjustments for the effects of the items noted above pertaining to UJVs that were allocable to our ownership interest in the UJVs. We believe this to be a useful supplemental measure alongside Diluted FFO as it excludes gains and losses from certain investing and financing activities and certain other items that we believe are not closely correlated to (or associated with) our operating performance. We believe that net income is the most directly comparable GAAP measure to this non-GAAP measure. This measure has essentially the same limitations as Diluted FFO, as well as the further limitation of not reflecting the effects of the excluded items; we compensate for these limitations in essentially the same manner as described above for Diluted FFO.
Diluted FFO per share is (1) Diluted FFO divided by (2) the sum of the (a) weighted average common shares outstanding during a period, (b) weighted average common units outstanding during a period and (c) weighted average number of potential additional common shares that would have been outstanding during a period if other securities that are convertible or exchangeable into common shares were converted or exchanged. We believe that Diluted FFO per share is useful to investors because it provides investors with a further context for evaluating our FFO results in the same manner that investors use earnings per share (“EPS”) in evaluating net income available to common shareholders. In addition, since most equity REITs provide Diluted FFO per share information to the investment community, we believe that Diluted FFO per share is a useful supplemental measure for comparing us to other equity REITs. We believe that diluted EPS is the most directly comparable GAAP measure to Diluted FFO per share. Diluted FFO per share has most of the same limitations as Diluted FFO (described above); management compensates for these limitations in essentially the same manner as described above for Diluted FFO.
Diluted FFO per share, as adjusted for comparability is (1) Diluted FFO, as adjusted for comparability divided by (2) the sum of the (a) weighted average common shares outstanding during a period, (b) weighted average common units outstanding during a period and (c) weighted average number of potential additional common shares that would have been outstanding during a period if other securities that are convertible or exchangeable into common shares were converted or exchanged. We believe that this measure is useful to investors because it provides investors with a further context for evaluating our FFO results. We believe this to be a useful supplemental measure alongside Diluted FFO per share as it excludes gains and losses from certain investing and financing activities and certain other items that we believe are not closely correlated to (or associated with) our operating performance. We believe that diluted EPS is the most directly comparable GAAP measure to this per share measure. This measure has most of the same limitations as Diluted FFO (described above) as well as the further limitation of not reflecting the effects of the excluded items; we compensate for these limitations in essentially the same manner as described above for Diluted FFO.
The computations for all of the above measures on a diluted basis assume the conversion of common units in COPLP but do not assume the conversion of other securities that are convertible into common shares if the conversion of those securities would increase per share measures in a given period.

Property Additions
The table below sets forth the major components of our additions to properties for the three months ended March 31, 2022 (in thousands):

Development | $ | 63,997 |
Tenant improvements on operating properties (1) | 6,824 |
Capital improvements on operating properties | 6,832 |
| $ | 77,653 |

(1)Tenant improvement costs incurred on newly-developed properties are classified in this table as development and redevelopment.
Cash Flows
Net cash flow from operating activities increased $12.0 million when comparing the three months ended March 31, 2022 and 2021 due primarily to a decrease in interest expense paid resulting from debt refinancings completed in 2021 that affected the timing of our interest payments on unsecured senior notes and reduced the borrowing rates on such notes.
Net cash flow provided by investing activities increased $177.0 million when comparing the three months ended March 31, 2022 and 2021 due primarily to $220.8 million in proceeds from properties sold in the current period (including our wholesale data center), partially offset by a $34.4 million increase in cash outlays for development and redevelopment of properties in the current period.
Net cash flow used in financing activities in the three months ended March 31, 2022 was $150.4 million, and included the following:
•net repayments of debt borrowings during the period of $116.8 million; and
•dividends to common shareholders of $30.9 million.
Net cash flow provided by financing activities in the three months ended March 31, 2021 was $50.4 million, and included the following:
•net proceeds from debt borrowings of $87.9 million, which included the net increase from our issuance of 2.75% Notes and purchase of 3.60% Notes and 5.25% Notes (and related early extinguishment costs); offset in part by
•dividends to common shareholders of $30.9 million.
Supplemental Guarantor Information
As of March 31, 2022, COPLP had several series of unsecured senior notes outstanding that were issued in transactions registered with the SEC under the Securities Act of 1933, as amended. These notes are COPLP’s direct, senior unsecured and unsubordinated obligations and rank equally in right of payment with all of COPLP’s existing and future senior unsecured and unsubordinated indebtedness. However, these notes are effectively subordinated in right of payment to COPLP’s existing and future secured indebtedness. The notes are also effectively subordinated in right of payment to all existing and future liabilities and other indebtedness, whether secured or unsecured, of COPLP's subsidiaries. COPT fully and unconditionally guarantees COPLP’s obligations under these notes. COPT’s guarantees of these notes are senior unsecured obligations that rank equally in right of payment with other senior unsecured obligations of, or guarantees by, COPT. COPT itself does not hold any indebtedness, and its only material asset is its investment in COPLP.
As permitted under Rule 13-01(a)(4)(vi), we do not provide summarized financial information for the Operating Partnership since: the assets, liabilities, and results of operations of the Company and the Operating Partnership are not materially different than the corresponding amounts presented in the consolidated financial statements of the Company; and we believe that inclusion of such summarized financial information would be repetitive and not provide incremental value to investors.
Liquidity and Capital Resources
As of March 31, 2022, we had $19.3 million in cash and cash equivalents.
We have a Revolving Credit Facility with an aggregate commitment by the lenders of $800.0 million, with the ability for us to increase such commitment to $1.25 billion, provided that there is no default under the facility and subject to the approval of the lenders. We use this facility to initially fund much of the cash requirements from our investing activities, including property development/redevelopment costs, as well as certain debt balloon payments due upon maturity. We then subsequently pay down the facility using cash available from operations and proceeds from long-term borrowings, equity issuances and sales of interests in properties. The facility matures in March 2023, 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 under the facility
35

for each extension period. As of March 31, 2022, the maximum borrowing capacity under this facility totaled $800.0 million, of which $640.0 million was available.
Our senior unsecured debt is rated investment grade by the three major rating agencies. We aim to maintain an investment grade rating to enable us to use debt comprised of unsecured, primarily fixed-rate debt (including the effect of interest rate swaps) from public markets and banks. We also use secured nonrecourse debt from institutional lenders and banks primarily for joint venture financings. In addition, we periodically raise equity when we access the public equity markets by issuing common shares and, to a lesser extent, preferred shares.
We have a program in place under which we may offer and sell common shares in at-the-market stock offerings having an aggregate gross sales price of up to $300 million. Under this program, we may also, at our discretion, sell common shares under forward equity sales agreements. The use of a forward equity sales agreement would enable us to lock in a price on a sale of common shares when the agreement is executed but defer issuing the shares and receiving the sale proceeds until a later date.
We believe that our liquidity and capital resources are adequate for our near-term and longer-term requirements without necessitating property sales. However, we may dispose of interests in properties opportunistically or when market conditions otherwise warrant. In addition, we believe that we have the ability to raise additional equity by selling interests in data center shells through joint ventures.
Our material cash requirements, including contractual and other obligations, include:
•property operating expenses, including future lease obligations from us as a lessee;
•construction contract expenses;
•general and administrative expenses;
•debt service, including interest expense;
•property development/redevelopment costs;
•tenant and capital improvements and leasing costs for operating properties (expected to total approximately $70 million during the remainder of 2022);
•debt balloon payments due upon maturity; and
•dividends to our shareholders.
We expect to use cash flow from operations during the remainder of 2022 and annually thereafter for the foreseeable future to fund all of these cash requirements except for property development/redevelopment costs and debt balloon payments due upon maturity.
During the remainder of 2022, we expect to spend approximately $230 million on development/redevelopment costs, most of which was contractually obligated as of March 31, 2022; we expect to fund these cash requirements using, in part, any available remaining cash flow from operations, with the balance funded primarily using borrowings under our Revolving Credit Facility, at least initially. As of March 31, 2022, we had $100 million in debt balloon payments due in December 2022 that we expect to repay using borrowings under our Revolving Credit Facility or proceeds from new long-term debt borrowings. As we use our Revolving Credit Facility to fund development/redevelopment costs and debt balloon payments, we intend to free up borrowing capacity by paying it down using proceeds from sales of interests in data center shells, property sales, new long-term debt borrowings and/or issuing common shares.
Beyond 2022, we expect to continue to actively develop and redevelop properties and fund using, in part, any available remaining cash flow from operations, with most of the balance funded initially using borrowings under our Revolving Credit Facility.
We provide disclosure in our consolidated financial statements on our future lessee obligations (expected to be funded primarily by cash flow from operations) in Note 5 and future debt obligations (expected to be refinanced by new debt borrowings or funded by future equity issuances and/or sales of interests in properties) in Note 9.
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 March 31, 2022, we were compliant with these covenants.

Item 3. 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.
The following table sets forth as of March 31, 2022 our debt obligations and weighted average interest rates on debt maturing each year (dollars in thousands):

| For the Periods Ending December 31, |  |
| 2022 |  | 2023 |  | 2024 |  | 2025 |  | 2026 |  | Thereafter |  | Total
Debt: |  |  |  |  |  |  |  |  |  |  |  |  |
Fixed rate debt (1) | $ | 2,154 |  |  | $ | 18,413 |  |  | $ | 29,443 |  |  | $ | 1,302 |  |  | $ | 436,140 |  |  | $ | 1,400,000 |  |  | $ | 1,887,452 |
Weighted average interest rate | 3.84% |  | 3.94% |  | 4.42% |  | 3.23% |  | 2.38% |  | 2.58% |  | 2.58%
Variable rate debt (2) | $ | 100,405 |  |  | $ | 160,540 |  |  | $ | 540 |  |  | $ | 22,415 |  |  | $ | 10,160 |  |  | $ | — |  |  | $ | 294,060 |
Weighted average interest rate (3) | 1.48% |  | 1.38% |  | 1.74% |  | 1.78% |  | 1.68% |  | —% |  | 1.46%

(1)Represents principal maturities only and therefore excludes net discounts and deferred financing costs of $24.7 million.
(2)As of March 31, 2022, maturities in 2023 included $160.0 million that may be extended to 2024, subject to certain conditions.
(3)The amounts reflected above used interest rates as of March 31, 2022 for variable rate debt.
The fair value of our debt was $2.2 billion as of March 31, 2022. If interest rates had been 1% lower, the fair value of our fixed-rate debt would have increased by approximately $130 million as of March 31, 2022.
See Note 10 to our consolidated financial statements for information pertaining to interest rate swap contracts in place as of March 31, 2022 and their respective fair values.
Based on our variable-rate debt balances, including the effect of interest rate swap contracts, our interest expense would have increased by $174,000 in the three months ended March 31, 2022 if the applicable LIBOR rate was 1% higher.
Item 4. Controls and Procedures
(a) Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of March 31, 2022. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of March 31, 2022 were functioning effectively to provide reasonable assurance that the information required to be disclosed in reports filed or submitted under the Securities Exchange Act of 1934 is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and (ii) accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
(b) Change in Internal Control over Financial Reporting
No change in our internal control over financial reporting occurred during the most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
PART II: OTHER INFORMATION
Item 1. Legal Proceedings
We are not currently involved in any material litigation nor, to our knowledge, is any material litigation currently threatened against us (other than routine litigation arising in the ordinary course of business, substantially all of which is expected to be covered by liability insurance).
Item 1A. Risk Factors
There have been no material changes to the risk factors included in our 2021 Annual Report on Form 10-K.
