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,~~June 30, 2021, our properties included the following:

•~~182~~183 properties totaling ~~21.0~~21.1 million square feet comprised of ~~16.3~~16.4 million square feet in ~~156~~157 office properties and 4.7 million square feet in 26 single-tenant data center shell properties (“data center shells”). We owned 1719 of these data center shells through unconsolidated real estate joint ventures;

•a wholesale data center with a critical load of 19.25 megawatts;

•1014 properties under development (8or redevelopment (11 office properties and 23 data center shells), including 3 partially-operational properties, that we estimate will total approximately ~~1.4~~2.0 million square feet upon completion; and

•approximately ~~820~~770 acres of land controlled for future development that we believe could be developed into approximately ~~10.4~~9.2 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,~~June 30, 2021, COPT owned 98.3% of the outstanding COPLP common units (“common units”) and there were 0 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

The 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

910

of and for the year ended December 31, 2020 included in the Company’s and Operating Partnership’s 2020 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 the Company’s and Operating Partnership’s 2020 Annual Report on Form 10-K as updated for our adoption of recent accounting pronouncements discussed below.

Reclassification

We reclassified certain amounts from the prior period to conform to the current period presentation of our consolidated financial statements with no effect on previously reported net income or equity.

Recent Accounting Pronouncements

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. ~~We froze additional entry into the plan effective~~Effective December 31, ~~2019.~~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 ~~$3.0~~$2.7 million as of ~~March 31,~~June 30, 2021, 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,~~June 30, 2021, we assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivatives and determined that these adjustments are not significant. As a result, we determined that our interest rate derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

The carrying values of cash and cash equivalents, restricted cash, accounts receivable, other assets (excluding investing receivables) and accounts payable and accrued expenses are reasonable estimates of their fair values because of the short maturities of these instruments. The fair values of our investing receivables, as disclosed in Note 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 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

1011

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 sets forth our financial assets and liabilities accounted for at fair value on a recurring basis as of ~~March 31,~~June 30, 2021 and the hierarchy level of inputs used in measuring their respective fair values under applicable accounting standards (in thousands):

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

On March 11, 2021, we issued $600.0 million of 2.75% Senior Notes due 2031 (the “2.75% Notes”) at an initial offering price of 98.95% of their face value. The proceeds from this issuance, after deducting underwriting discounts, but before other offering expenses, were $589.8 million. The notes mature on April 15, 2031. We may redeem the 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 of 25 basis points, plus accrued and unpaid interest thereon to the date of redemption. However, 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 redemption date. These notes are unconditionally guaranteed by COPT. The carrying value of these notes reflects an unamortized discount totaling ~~$10.1~~$9.9 million as of ~~March 31,~~June 30, 2021. The effective interest rate under the notes, including amortization of discount and issuance costs, was 2.94%.

With regard to our 3.60% Senior Notes due 2023 (the “3.60% Notes”) and 5.25% Senior Notes due 2024 (the “5.25% Notes”), we:

•effective March 11, 2021, purchased pursuant to tender offers $184.4 million of 3.60% Notes for $196.7 million and $145.6 million of 5.25% Notes for $164.7 million, plus accrued ~~interest. In connection with these purchases, we recognized a loss on early extinguishment of debt of $33.2 million in the three months ended March 31, 2021;~~interest; and

•on April 12, 2021, redeemed the remaining $165.6 million of 3.60% Notes for $176.3 million and $104.4 million of 5.25% Notes for $117.7 million, plus accrued ~~interest,~~interest.

In connection with these purchases and redemptions, we recognized ~~an additional~~a loss on early extinguishment of debt of ~~approximately $25 million.~~$25.2 million in the three months ended June 30, 2021 and $58.4 million in the six months ended June 30, 2021.

Certain of our debt instruments require that we comply with a number of restrictive financial covenants. As of ~~March 31,~~June 30, 2021, we were compliant with these financial covenants.

We capitalized interest costs of ~~$1.8~~$1.7 million in the three months ended ~~March 31,~~June 30, 2021, ~~and $3.4~~$3.2 million in the three months ended ~~March 31,~~June 30, 2020, $3.5 million in the six months ended June 30, 2021 and $6.5 million in the six months ended June 30, 2020.

Based on the fair value of our derivatives as of ~~March 31,~~June 30, 2021, we estimate that approximately $4.7 million of losses will be reclassified from AOCL as an increase to interest expense over the next 12 months.

We have agreements with each of our interest rate derivative counterparties that contain provisions under which, if we default or are capable of being declared in default on defined levels of our indebtedness, we could also be declared in default on our derivative obligations. Failure to comply with the loan covenant provisions could result in our being declared in default on any derivative instrument obligations covered by the agreements. As of ~~March 31,~~June 30, 2021, we were not in default with any of these provisions. As of ~~March 31,~~June 30, 2021, the fair value of interest rate derivatives in a liability position related to these agreements was ~~$7.7~~$6.7 million, excluding the effects of accrued interest and credit valuation adjustments. As of ~~March 31,~~June 30, 2021, 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 ~~$8.1~~$7.1 million as of ~~March 31,~~June 30, 2021.

11. Redeemable Noncontrolling Interests

Our partners in 2 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,					For the Six Months Ended June 30,
		2021		2020			2021		2020
Beginning balance	Beginning balance	$	25,430	$	29,431	Beginning balance	$	25,430	$	29,431

Distributions to noncontrolling interests	Distributions to noncontrolling interests	(399)		(11,578)		Distributions to noncontrolling interests	(1,165)		(12,695)
Net income attributable to noncontrolling interests	Net income attributable to noncontrolling interests	412		958		Net income attributable to noncontrolling interests	1,153		2,075
Adjustment to arrive at fair value of interests	Adjustment to arrive at fair value of interests	482		4,101		Adjustment to arrive at fair value of interests	622		4,337
Ending balance	Ending balance	$	25,925	$	22,912	Ending balance	$	26,040	$	23,148

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

Common Shares

As of ~~March 31,~~June 30, 2021, 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.

During the ~~three~~six months ended ~~March 31,~~June 30, 2021, certain COPLP limited partners converted 8,054 common units in COPLP for an equal number of common shares.

We declared dividends per common share of $0.275 in the three months ended ~~March 31,~~June 30, 2021 and 2020 and $0.550 in the six months ended June 30, 2021 and 2020.

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~~June 2021.

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,~~June 30, 2021 and December 31, 2020 were not significant. We did not recognize any interest income on notes receivable on nonaccrual status during the three or six months ended ~~March 31,~~June 30, 2021 and 2020.

14. Information by Business Segment

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

We measure the performance of our segments through the measure we define as net operating income from real estate operations (“NOI from real estate operations”), which includes: real estate revenues and property operating expenses; and the net of revenues and property operating expenses of real estate operations owned through unconsolidated real estate joint ventures (“UJVs”) that is allocable to 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):

The accounting policies of the segments are the same as those used to prepare our consolidated financial statements. 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, ~~(expense),~~ income taxes and noncontrolling interests because these items represent general corporate or non-operating property items not attributable to segments.

Revenue allocated to the remaining performance obligations under existing contracts as of ~~March 31,~~June 30, 2021 that will be recognized as revenue in future periods was ~~$176.6~~$171.7 million, approximately ~~$74~~$69 million of which we expect to recognize during the remainder of 2021.

We have 0 deferred incremental costs incurred to obtain or fulfill our construction contracts or other service revenues and had no significant credit loss expense on construction contracts receivable or unbilled construction revenue in the three or six months ended ~~March 31,~~June 30, 2021 and 2020.

16. Share-Based Compensation

Restricted Shares

During the ~~three~~six months ended ~~March 31,~~June 30, 2021, certain employees and a non-employee ~~member~~members of our Board of Trustees (“~~Trustee”~~Trustees”) were granted a total of ~~139,646~~161,345 restricted common shares with an aggregate grant date fair value of ~~$3.6~~$4.2 million (weighted average of ~~$26.00~~$26.19 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. Restricted shares granted to non-employee Trustees vest on the first anniversary of the grant date, provided that the Trustee remains in his or her

position. During the ~~three~~six months ended ~~March 31,~~June 30, 2021, forfeiture restrictions lapsed on ~~131,573~~150,751 previously issued common shares; these shares had a weighted average grant date fair value of ~~$25.82~~$25.75 per share, and the aggregate intrinsic value of the shares on the vesting dates was ~~$3.4~~$3.9 million.

Performance Share Awards (“PSUs”)

We issued 93,824 common shares on February 3, 2021 to executives in settlement of PSUs granted in 2018, representing 200% of the target awards for those PSUs.

Profit Interest Units in COPLP (“PIUs”)

We granted 2 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~~six months ended ~~March 31,~~June 30, 2021, we granted ~~80,319~~93,983 TB-PIUs with an aggregate grant date fair value of ~~$2.1~~$2.5 million ~~($26.00~~(weighted average of $26.16 per TB-PIU) to senior management team ~~members. These~~members and certain non-employee Trustees. TB-PIUs granted to senior management team members generally vest in equal annual increments over a three-year period beginning on the first anniversary of the date of grant provided that the employee remains employed by us. TB-PIUs granted to non-employee Trustees vest on the first anniversary of the grant date, provided that the Trustee remains in his or her position. Prior to vesting, TB-PIUs carry substantially the same rights to distributions as non-PIU common units but carry no redemption rights. During the ~~three~~six months ended ~~March 31,~~June 30, 2021, forfeiture restrictions lapsed on ~~32,619~~40,591 previously issued TB-PIUs; these TB-PIUs had a weighted average grant date fair value of ~~$25.55~~$25.14 per unit, and the aggregate intrinsic value of the TB-PIUs on the vesting date was ~~$848,000.~~$1.1 million.

PB-PIUs

On January 1, 2021, we granted certain senior management team members 227,544 PB-PIUs with a three-year performance period concluding on the earlier of December 31, 2023 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 2 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 $3.4 million ($30.03 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 $26.08; expected volatility for common shares of 34.7%; and a risk-free interest rate of 0.18%.

23Deferred Share Awards

During the six months ended June 30, 2021, a non-employee Trustee was granted 3,416 deferred share awards with an aggregate grant date fair value of $93,000 ($27.12 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).

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 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,~~June 30, 2021, management believes that it is reasonably possible that we could recognize a loss of up to ~~$3.2~~$3.3 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 3 properties in Dayton, New Jersey, we agreed to provide certain environmental indemnifications limited to $19 million in the aggregate. We have insurance coverage in place to mitigate much of any potential future losses that may result from these indemnification agreements.

Tax Incremental Financing Obligation

Anne Arundel County, Maryland issued tax incremental financing bonds to third-party investors in order to finance public improvements needed in connection with our project known as the National Business Park. These bonds had a remaining principal balance of approximately $33 million as of ~~March 31,~~June 30, 2021. 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,~~June 30, 2021, we do not expect any such future fundings will be required.

Effects of COVID-19

population has resumed a ~~reluctance by much of the population~~return to ~~engage in certain activities while the pandemic is still active. In addition,~~normal activities.However, there continues to be significant uncertainty regarding the duration and extent of the pandemic due to ~~such~~ factors such as the ~~resurgence~~continuing spread of the virus ~~emergence~~(including recent increases in new case volumes in much of ~~variants in some areas and~~the United States), the pace of vaccination ~~efforts.~~efforts (including potential future booster shots) and vaccine efficacy in terms of duration and against variants of the virus. While the pandemic has impacted the operations of much of the commercial real estate industry, we believe that we have been less susceptible to such impact due to our portfolio’s significant concentration in Defense/IT Locations. As a result, we believe that we have not been significantly affected by the pandemic.

COVID-19, along with measures instituted to prevent spread, may adversely affect us in many ways, including, but not limited to:

•disruption of our tenants’ operations, which could adversely affect their ability, or willingness, to sustain their businesses and/or fulfill their lease obligations;

•our ability to maintain occupancy in our properties and obtain new leases for unoccupied and new development space at favorable terms or at all;

•shortages in supply of products or services from our and our tenants’ vendors that are needed for us and our tenants to operate effectively, and which could lead to increased costs for such products and services;

•access to debt and equity capital on attractive terms or at all. Severe disruption and instability in the global financial markets or deteriorations in credit and financing conditions may affect our or our tenants’ ability to access capital necessary to fund operations, refinance debt or fund planned investments on a timely basis, and may adversely affect the valuation of financial assets and liabilities;

•our and our tenants’ ability to continue or complete planned development, including the potential for delays in the supply of materials or labor necessary for development; and

•an increase in the pace of businesses implementing remote work arrangements over the long-term, which would adversely effect demand for office space.

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

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

During the ~~three~~six months ended ~~March 31,~~June 30, 2021, we:

•finished the period with our office and data center shell portfolio ~~93.8%~~93.5% occupied and ~~94.7%~~94.3% leased;

•placed into service ~~46,000~~243,000 square feet in ~~one~~four newly-developed office ~~property~~properties that ~~was 100.0%~~were 77.7% leased as of ~~March 31,~~June 30, 2021; ~~and~~

•refinanced certain unsecured senior notes issuances with a new unsecured senior note issuance ~~effective March 11, 2021~~ by:

◦issuing $600.0 million of 2.75% Notes at an initial offering price of 98.95% of their face ~~value.~~value on March 11, 2021. The proceeds from this issuance, after deducting underwriting discounts but before other offering expenses, were $589.8 million; and

◦purchasing ~~pursuant to tender offers $184.4~~or redeeming $350.0 million of 3.60% Notes ~~for $196.7 million~~(52.7% of such notes effective March 11, 2021 and ~~$145.6~~the remaining notes on April 12, 2021) and $250.0 million of 5.25% Notes (58.2% of such notes effective March 11, 2021 and the remaining notes on April 12, 2021) for ~~$164.7~~$373.1 million and $282.4 million, respectively, plus accrued interest. In connection with these purchases, we recognized a loss on early extinguishment of debt ~~of $33.2 million~~ in the three months and six months ended ~~March 31, 2021;~~June 30, 2021 of $25.2 million and

◦~~initiating the redemption of the remaining $165.6~~ $58.4 million, of 3.60% Notes and $104.4 million of 5.25% Notes, which was completed on April 12, 2021 for $294.0 million, plus accrued interest, resulting in recognition of an additional loss on early extinguishment of debt of approximately $25 million.respectively.

We ~~initially~~ used ~~the remaining proceeds from the 2.75% Notes issuance on March 11, 2021 to repay borrowings under our Revolving Credit Facility and for general corporate purposes. We subsequently used primarily~~ borrowings under our Revolving Credit Facility to fund the ~~redemption~~net cash outlay resulting from this refinancing; and

•sold a 90% interest in two data center shell properties in Northern Virginia on June 2, 2021 based on an aggregate property value of $118.8 million and retained a 10% interest in the ~~remaining 3.60% Notes and 5.25% Notes on April 12, 2021.~~properties through B RE COPT DC JV III LLC, a newly-formed joint venture. Our partner in the joint venture acquired the 90% interest from us for $106.9 million, which was used by us 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 cash for short and long-term capital needs; and

•our commitments and contingencies.

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.

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, construction costs and property values;

•adverse changes in the real estate markets, including, among other things, increased competition with other companies;

•risks and uncertainties regarding the impact of the COVID-19 pandemic, and similar pandemics, along with restrictive measures instituted to prevent spread, on our business, the real estate industry and national, regional and local economic conditions;

•governmental actions and initiatives, including risks associated with the impact of a prolonged government shutdown or budgetary reductions or impasses, such as a reduction in rental revenues, non-renewal of leases and/or reduced or delayed demand for additional space by our strategic customers;

•our ability to borrow on favorable terms;

2730

•risks of real estate acquisition and development activities, including, among other things, risks that development projects may not be completed on schedule, that tenants may not take occupancy or pay rent or that development or operating costs may be greater than anticipated;

•risks of investing through joint venture structures, including risks that our joint venture partners may not fulfill their financial obligations as investors or may take actions that are inconsistent with our objectives;

•changes in our plans for properties or views of market economic conditions or failure to obtain development rights, either of which could result in recognition of significant impairment losses;

•our ability to satisfy and operate effectively under Federal income tax rules relating to real estate investment trusts and partnerships;

•possible adverse changes in tax laws;

•the dilutive effects of issuing additional common shares;

•our ability to achieve projected results;

•security breaches relating to cyber attacks, cyber intrusions or other factors; and

•environmental requirements.

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

Effects of COVID-19

As of the date of this filing, spread of the coronavirus, or COVID-19, continues world- and ~~nation-wide, and is expected~~nation-wide. To date, the United States has made significant progress with the pandemic relative to ~~continue at least until vaccinations have been administered to most~~the beginning of the ~~population. Some businesses continue to be hindered to varying extents by~~year, with significantly lower new case volumes and a significant increase in the ~~effects~~proportion of the population that has been vaccinated. With this progress, most restrictive measures previously instituted to control spread ~~operational challenges resulting from social distancing requirements/expectations and/or a reluctance by much~~have been gradually lifted and an increasing proportion of the population has resumed a return to ~~engage in certain activities while the pandemic is still active. In addition,~~normal activities. However, there continues to be significant uncertainty regarding the duration and extent of the pandemic due to ~~such~~ factors such as the ~~resurgence~~continuing spread of the virus ~~emergence~~(including recent increases in new case volumes in much of ~~variants in some areas and~~the United States), the pace of vaccination ~~efforts.~~efforts (including potential future booster shots) and vaccine efficacy in terms of duration and against variants of the virus.

While the pandemic has impacted the operations of much of the commercial real estate industry, we believe that we have been less susceptible to such impact due to our portfolio’s significant concentration in Defense/IT Locations. As a result, ~~we believe that~~ our results of operations ~~have~~were not ~~been~~ significantly affected by the pandemic. For the three and six months ended ~~March 31,~~June 30, 2021, our:

•Same Properties NOI from real estate operations ~~decreased $922,000~~increased for the three and six months ended June 30, 2021 relative to the ~~three months ended March 31, 2020. This decrease included~~comparable 2020 periods by $2.1 million and $1.1 million, respectively, and was only minimally affected by the pandemic-related net effect of ~~a $542,000 decrease~~lower provisions for collectability losses, offset in part by lower parking revenue, ~~attributable primarily~~in the 2021 periods relative to the ~~pandemic;~~2020 periods; and

•lease revenue collections were not significantly affected by the pandemic. After agreeing to deferred payment arrangements for approximately $2.6 million in lease receivables last year (most of which was repaid by June 30, 2021), we did not agree to significant additional arrangements to date in ~~the current period.~~2021.

While we do not currently expect that the pandemic will significantly affect our future results of operations, financial condition or cash flows, we believe that the impact will be dependent on future developments, including the duration and extent of the pandemic, the prevalence, strength and duration of restrictive measures and the resulting effects on our tenants, potential future tenants, the commercial real estate industry and the broader economy, all of which are uncertain and difficult to predict. Nevertheless, we believe at this time that there is more inherent risk associated with the operations of our Regional Office properties than our Defense/IT Locations.

While we do not believe that our development leasing and ability to renew leases scheduled to expire have been significantly affected by the pandemic, we do believe that the impact of the restrictive measures and the economic uncertainty caused by the pandemic has impacted our timing and volume of vacant space leasing, and may continue to do so in the future.

The pandemic enhances the risk of us being able to stay on pace to complete development and begin operations on schedule due to the potential for delays from: jurisdictional permitting and inspections; factories’ ability to provide materials; and possible labor ~~quarantines.~~shortages. These types of issues have not significantly affected us to date but could in the future, depending on pandemic related developments.

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

During the ~~three~~six months ended ~~March 31,~~June 30, 2021, we completed ~~258,000~~1.7 million square feet of leasing, including: renewed leases on ~~154,000~~815,000 square feet, representing ~~51.8%~~78.3% of the square footage of our lease expirations (including the effect of early ~~renewals)~~renewals and excluding vacated space removed from service for redevelopment); ~~93,000~~205,000 square feet of vacant space; and ~~11,000~~641,000 square feet of development space.

Wholesale Data Center

Our 19.25 megawatt wholesale data center was 86.7% leased as of ~~March 31,~~June 30, 2021 and December 31, 2020. An 11.25 megawatt lease that expired in August 2020 remains in place until renewed by both parties or terminated by either party.

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; 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”). 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.

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

Since both of the measures discussed above exclude certain items includable in net income, reliance on these measures has limitations; management compensates for these limitations by using the measures simply as supplemental measures that are considered alongside other GAAP and non-GAAP measures. A reconciliation of NOI from real estate operations and NOI from service operations to net income reported on our consolidated statements of operations is provided in Note 14 to our consolidated financial statements.

Our Same Properties pool consisted of ~~161~~158 properties, comprising ~~84.7%~~81.9% of our office and data center shell portfolio’s square footage as of ~~March 31,~~June 30, 2021. This pool of properties changed from the pool used for purposes of comparing 2020 and 2019 in our 2020 Annual Report on Form 10-K due to ~~the~~the: addition of eight properties placed in service and 100% operational

3134

on or before January 1, 2020 and nine properties owned through an unconsolidated real estate joint venture that was formed in ~~2019.~~2019; and removal of two properties in which we sold a 90% interest and one property reclassified as redevelopment.

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

•the increase for our Same Properties pool ~~reflects a net decrease~~was due primarily to ~~increased operating expenses (net of related recoveries) due mostly to higher snow removal costs, as well as~~ lower ~~parking revenue attributable primarily to the pandemic, partially offset by~~provisions for collectability losses and higher lease termination ~~fees;~~revenue in the current period;

•developed and redeveloped properties placed in service reflects the effect of 1315 properties placed in service in 2020 and 2021; and

•dispositions, net of retained interest in newly-formed ~~UJV~~UJVs reflects the effect of our decrease in ownership of eight data center shells ~~occurring~~ in ~~2020.~~2020 and two in 2021.

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 an insignificant amount of income relative to our real estate operations.

Depreciation and amortization associated with real estate operations

The increase in depreciation and amortization associated with real estate operations was mostly attributable to newly-developed properties placed in service.

Gain on sales of real estate

The gain on sales of real estate was due to our sale of a 90% interest in two data center shell properties in the current period.

Loss on extinguishment of debt

The loss on early extinguishment of debt recognized in the current period was attributable to our redemption of the remaining 3.60% Notes and 5.25% Notes in the current period.

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

collectability losses; and higher lease termination revenue in the current period; offset in part by higher snow removal costs and lower parking revenue in the current period;

•developed and redeveloped properties placed in service reflects the effect of 15 properties placed in service in 2020 and 2021; and

•dispositions, net of retained interest in newly-formed UJVs reflects the effect of our decrease in ownership of eight data center shells in 2020 and two in 2021.

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 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 on noncontrolling interests resulting from capital events; and certain other expenses that we believe are not closely correlated with our operating performance. This measure also includes adjustments for the effects of the items noted above pertaining to UJVs that were allocable to our ownership interest in the UJVs. We believe this to be a useful supplemental measure alongside Diluted FFO as it excludes gains and losses from certain investing and financing activities and certain other items that we believe are not closely correlated to (or associated with) our operating performance. We believe that net income is the most directly comparable GAAP measure to this non-GAAP measure. This measure has essentially the same limitations as Diluted FFO, as well as the further limitation of not reflecting the effects of the excluded items; we compensate for these limitations in essentially the same manner as described above for Diluted FFO.

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

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

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

Property Additions

The table below sets forth the major components of our additions to properties for the ~~three~~six months ended ~~March 31,~~June 30, 2021 (in thousands):


Development	$	~~40,041~~96,308

Tenant improvements on operating properties (1)	~~5,843~~12,275
Capital improvements on operating properties	~~3,627~~10,398
	$	~~49,511~~118,981

(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 ~~decreased $21.5~~increased $1.5 million when comparing the ~~three~~six months ended ~~March 31,~~June 30, 2021 and 2020 due ~~primarily to: increased~~to an increase in cash ~~paid for interest expense due to the timing of our purchase of 3.60% Notes and 5.25% Notes, at which time accrued interest was paid; increased cash paid for property operating expenses~~flow from real estate operations resulting ~~primarily~~ from ~~higher snow removal costs in the current period and~~ the growth of our property ~~portfolio; and~~portfolio, which was partially offset by a decrease associated with the timing of cash flow from third-party construction projects. While our property portfolio was larger in the current period, our revenues received from real estate operations did not change significantly due primarily to delayed lease payments (most of which were subsequently received) from the USG at several properties and scheduled free rent periods for certain leases on newly-developed properties and renewals of existing space.

Net cash flow used in investing activities decreased ~~$41.6~~$196.7 million when comparing the ~~three~~six months ended ~~March 31,~~June 30, 2021 and 2020 due primarily to ~~decreased~~$114.4 million in property disposition proceeds mostly from our sale in 2021 of a 90% interest in two data center shells and a $74.4 million decrease in cash outlays for development and redevelopment of ~~properties and for tenant improvements on operating~~ properties.

Net cash flow used in financing activities in the six months ended June 30, 2021 was $107.7 million, and included the following:

•net cash outlays from debt borrowings of $37.4 million, which included the net decrease from our purchase and redemption of 3.60% Notes and 5.25% Notes (and related early extinguishment costs) and issuance of 2.75% Notes; and

•dividends to common shareholders of $61.7 million.

Net cash flow provided by financing activities in the ~~three~~six months ended ~~March 31, 2021~~June 30, 2020 was ~~$50.4~~$98.5 million, and included the following:

•net proceeds from debt borrowings of ~~$87.9 million, which included the net increase from our issuance of the 2.75% Notes and the purchase of the 3.60% Notes and 5.25% Notes (and related early extinguishment costs); offset in part by~~

•~~dividends to common shareholders of $30.9 million.~~

~~Net cash flow provided by financing activities in the three months ended March 31, 2020 was $197.0 million, and included the following:~~

•~~net proceeds from debt borrowings of $245.6~~$179.3 million; offset in part by

•dividends to common shareholders of ~~$30.8~~$61.7 million.

Supplemental Guarantor Information

As of ~~March 31,~~June 30, 2021, 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.

In March 2020, the SEC adopted amendments to Rule 3-10 of Regulation S-X and adopted Rule 13-01 of Regulation S-X to simplify disclosure requirements related to certain registered securities that became effective on January 4, 2021. As a result of these amendments, subsidiary issuers of obligations guaranteed by the parent are not required to provide separate financial statements, provided that the subsidiary obligor is consolidated into the parent company’s consolidated financial statements, the parent guarantee is “full and unconditional” and the alternative disclosure required by Rule 13-01 is provided, which includes narrative disclosure and, subject to certain exceptions, summarized financial information. Accordingly, we no longer present separate consolidated financial statements for the Operating Partnership. Furthermore, as permitted under Rule 13-01(a)(4)(vi),

we have excluded 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

Our primary cash requirements are for operating expenses, debt service, development of new properties, improvements to existing properties and dividends to our shareholders. 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, dividends to our shareholders, distributions to COPLP’s unitholders and improvements to existing properties. As of ~~March 31,~~June 30, 2021, we had ~~$36.1~~$17.2 million in cash and cash equivalents.

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 primarily for joint venture financings. In addition, we periodically raise equity when we access the public equity markets 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 cash available from operations and proceeds from long-term borrowings, equity issuances and sales of interests in properties. The lenders’ aggregate commitment under the facility is $800.0 million, with the ability for us to increase the lenders’ aggregate commitment to $1.25 billion, provided that there is no default under the facility and subject to the approval of the lenders. The facility matures 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 for each extension period. As of ~~March 31,~~June 30, 2021, the maximum borrowing capacity under this facility totaled $800.0 million, ~~all~~ of which $631.0 million was available.

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 receiving the proceeds from the sale 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.

(1)The contractual obligations set forth in this table exclude contracts for property operations and certain other contracts entered into in the normal course of business. Also excluded are accruals and payables incurred and interest rate derivative liabilities, which are reflected in our reported liabilities (although debt and lease liabilities are included on the table).

(2)Represents scheduled principal amortization payments and maturities only and therefore excludes net debt discounts and deferred financing costs of ~~$23.7~~$21.4 million. ~~Maturities~~As of June 30, 2021, maturities in 2023 included ~~$270.0~~$169.0 million ~~in 2021 pertaining~~that may be extended to ~~our remaining 3.60% Notes and 5.25% Notes that were redeemed on April 12, 2021 using borrowings under our Revolving Credit Facility.~~2024, subject to certain conditions.

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

(4)Represents interest costs for our outstanding debt as of ~~March 31,~~June 30, 2021 for the terms of such debt. For variable rate debt, the amounts reflected above used ~~March 31,~~June 30, 2021 interest rates on variable rate debt in computing interest costs for the terms of such debt. We expect to pay these items using cash flow from operations.

(5)Represents contractual obligations pertaining to new development and redevelopment activities.

(6)Due to the long-term nature of certain development and construction contracts and leases included in these lines, the amounts reported in the table represent our estimate of the timing for the related obligations being payable.

(7)Represents contractual obligations pertaining to projects for which we are acting as construction manager on behalf of unrelated parties who are our clients. We expect to be reimbursed in full for these costs by our clients.

We expect to spend approximately ~~$225~~$150 million on development costs and approximately ~~$75~~$55 million on improvements and leasing costs for operating properties (including the commitments set forth in the table above) during the remainder of 2021. We expect to fund the development costs initially using primarily borrowings under our Revolving Credit Facility. We expect to fund improvements to existing operating properties using cash flow from operating activities.

Certain of our debt instruments require that we comply with a number of restrictive financial covenants, including maximum leverage ratio, unencumbered leverage ratio, minimum net worth, minimum fixed charge coverage, minimum unencumbered interest coverage ratio, minimum debt service and maximum secured indebtedness ratio. As of ~~March 31,~~June 30, 2021, we were compliant with these covenants.

Off-Balance Sheet Arrangements

We had no material off-balance sheet arrangements during the ~~three~~six months ended ~~March 31,~~June 30, 2021.

Inflation

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

Recent Accounting Pronouncements

See Note 2 to our consolidated financial statements for information regarding recent accounting pronouncements.

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,~~June 30, 2021 our debt obligations and weighted average interest rates on debt maturing each year (dollars in thousands):


		For the Periods Ending December 31,															For the Periods Ending December 31,
		2021		2022		2023		2024		2025		Thereafter		Total			2021		2022		2023		2024		2025		Thereafter		Total

(1)Represents principal maturities only and therefore excludes net discounts and deferred financing costs of ~~$23.7~~$21.4 million. ~~Maturities~~As of June 30, 2021, maturities in 2023 included ~~$270.0~~$169.0 million ~~in 2021 pertaining~~that may be extended to ~~our remaining 3.60% Notes and 5.25% Notes that were redeemed on April 12, 2021 using borrowings under our Revolving Credit Facility.~~2024, subject to certain conditions.

(2)The amounts reflected above used interest rates as of ~~March 31,~~June 30, 2021 for variable rate debt.

The fair value of our debt was $2.2 billion as of ~~March 31,~~June 30, 2021. If interest rates had been 1% lower, the fair value of our fixed-rate debt would have increased by approximately ~~$89~~$86 million as of ~~March 31,~~June 30, 2021.

See Note 10 to our consolidated financial statements for information pertaining to interest rate swap contracts in place as of ~~March 31,~~June 30, 2021 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 ~~$874,000~~$2.0 million in the ~~three~~six months ended ~~March 31,~~June 30, 2021 if the applicable LIBOR rate was 1% higher.

Item 4. Controls and Procedures
