1.    Organization

COPT Defense Properties (“CDP”) and subsidiaries (collectively, the “Company”, “we” or “us”) is a fully-integrated and self-managed real estate investment trust (“REIT”) focused on owning, operating and developing properties in locations proximate to, or sometimes containing, key U.S. Government (“USG”) defense installations and missions (which we refer to herein as our Defense/IT Portfolio). Our tenants include the USG and their defense contractors, who are primarily engaged in priority national security activities, and who generally require mission-critical and high security property enhancements. In September 2023, we changed our name from Corporate Office Properties Trust to COPT Defense Properties to better describe our investment strategy’s focus on locations serving our country’s priority defense activities. As of September 30, 2023, our Defense/IT Portfolio included:

•188 operating properties totaling 21.3 million square feet comprised of 15.8 million square feet in 159 office properties and 5.5 million square feet in 29 single-tenant data center shells. We owned 24 of these data center shells through unconsolidated real estate joint ventures;

•six properties under development (three office properties and three data center shells) that will total approximately 971,000 square feet upon completion; and

•approximately 670 acres of land controlled that we believe could be developed into approximately 8.1 million square feet.

We also owned eight other operating properties totaling 2.1 million square feet and approximately 50 acres of other developable land in the Greater Washington, DC/Baltimore region as of September 30, 2023.

We conduct almost all of our operations and own almost all of our assets through our operating partnership, COPT Defense Properties, L.P. (“CDPLP”) and subsidiaries (collectively, the “Operating Partnership”), of which CDP is the sole general partner. CDPLP owns real estate directly and through subsidiary partnerships and limited liability companies (“LLCs”).  In addition to owning real estate, CDPLP 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”). In September 2023, we changed CDPLP’s name from Corporate Office Properties, L.P. to COPT Defense Properties, L.P.

Equity interests in CDPLP are in the form of common and preferred units. As of September 30, 2023, CDP owned 97.9% of the outstanding CDPLP common units (“common units”) and there were no preferred units outstanding. Common units not owned by CDP carry certain redemption rights. The number of common units owned by CDP is equivalent to the number of outstanding common shares of beneficial interest (“common shares”) of CDP, and the entitlement of common units to quarterly distributions and payments in liquidation is substantially the same as that of CDP common shareholders.

In September 2023, the ticker symbol under which our common shares are publicly traded on the New York Stock Exchange (“NYSE”) changed from “OFC” to “CDP”.

2.    Summary of Significant Accounting Policies

Basis of Presentation

These consolidated financial statements include the accounts of CDP, the Operating Partnership, their subsidiaries and other entities in which CDP 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, 2022 included in our 2022 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

10

prepared using the accounting policies described in our 2022 Annual Report on Form 10-K.

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.

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 of mutual funds) 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. The balance of the plan, which was fully funded and totaled $1.7 million as of September 30, 2023, is included in the line entitled “prepaid expenses and other assets, net” on our consolidated balance sheets. 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, as disclosed in Note 9, 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 September 30, 2023, 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 8, 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. 

The table below sets forth our financial assets and liabilities accounted for at fair value on a recurring basis as of September 30, 2023 and the hierarchy level of inputs used in measuring their respective fair values under applicable accounting standards (in thousands):

Description	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable  Inputs (Level 3)		Total

Nonrecurring Fair Value Measurements

As part of our closing process for the three months ended September 30, 2023, we conducted our quarterly review of our portfolio of long-lived assets to be held and used for indicators of impairment. As a result of this process, we shortened the expected holding periods for six operating properties in our Other segment and a parcel of land located in Baltimore, Maryland, Northern Virginia and Washington, D.C. We determined that the carrying amount of the properties would not likely be recovered from the undiscounted cash flows from the operations and sales of the properties over the shortened holding periods. Accordingly, we recognized impairment losses of $252.8 million on these properties during the period. The combined fair value of these properties as of September 30, 2023 was $311.3 million, as determined using significant unobservable inputs (Level 3 of the fair value hierarchy).

The table below sets forth quantitative information about significant unobservable inputs used for the Level 3 fair value measurements reported above as of September 30, 2023 (dollars in thousands):

Valuation Technique	Fair Values on Measurement Date		Unobservable Input	Range (Weighted Average (1))
Discounted cash flow (2)	$	257,800	Terminal capitalization rate	6.5% - 9.5% (8.0%)
			Discount rate	7.5% - 10.5% (9.0%)
Comparable sales price (3)	$	53,500	Comparable sales price	N/A

(1)Weighted average calculation based on relative fair value.

(2)This technique was used for the operating properties in Baltimore, Maryland and Washington, D.C. For the properties in Baltimore, Maryland, the terminal capitalization rate was 9.5% and the discount rate was 10.5%. For the property in Washington, D.C., the terminal capitalization rate was 6.5% and the discount rate was 7.5%.

(3)This technique was used for the operating properties in Northern Virginia and a parcel of land in Baltimore, Maryland.

(2)Our investment in B RE COPT DC JV II LLC was lower than our share of the joint venture’s equity by $6.9 million as of September 30, 2023 and $7.0 million as of December 31, 2022 due to a difference between our cost basis and our share of the joint venture’s underlying equity in its net assets. We recognize adjustments to our share of the joint venture’s earnings and losses resulting from this basis difference in the underlying assets of the joint venture.

As described further in Note 4, on January 10, 2023, we sold a 90% interest in three data center shell properties in Northern Virginia and retained a 10% interest in the properties through Redshift JV LLC, a newly-formed joint venture. We concluded that the joint venture is a variable interest entity. Under the terms of the joint venture agreement, we and our partner receive returns in proportion to our investments, and our maximum exposure to losses is limited to our investment, subject to our share of certain indemnification obligations with respect to nonrecourse debt secured by the properties. The nature of our involvement in the activities of the joint venture does not give us power over decisions that significantly affect its economic performance.

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

On September 12, 2023, we issued $345.0 million aggregate principal amount of 5.25% Exchangeable Senior Notes due 2028 (the “5.25% Notes”) in a private placement. The proceeds from this issuance, after deducting the initial purchasers’ commissions, but before other offering expenses, were $336.4 million. The notes bear interest at a rate of 5.25% per year, payable semi-annually in arrears on March 15 and September 15 of each year, beginning on March 15, 2024. The notes mature on September 15, 2028 unless earlier exchanged, redeemed or repurchased.

Prior to the close of business on the business day immediately preceding June 15, 2028, the notes will be exchangeable at the option of the noteholders only in the event of certain circumstances and during certain periods defined under the terms of the

16

notes. On or after June 15, 2028, the notes will be exchangeable at the option of the holders at any time prior to the close of business on the business day immediately preceding the maturity date. Upon exchange, the principal amount of notes is payable in cash. The remainder of the exchange obligation, if any, as determined based on the exchange price per common share at the time of settlement, is payable in cash, common shares or a combination thereof at our election. The exchange rate of the notes initially equaled 33.3739 of our common shares per $1,000 principal amount of notes (equivalent to an initial exchange price of approximately $29.96 per common share). The exchange rate is subject to adjustment upon the occurrence of some events, but will not be adjusted for any accrued and unpaid interest.

We may redeem the notes at our option, in whole or in part, on any business day on or after September 21, 2026, and prior to the 51st scheduled trading day immediately preceding the maturity date, if the last reported sale price of our common shares has been at least 130% of the exchange price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. The redemption price will be equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

These notes are unconditionally guaranteed by CDP. The table below sets forth interest expense recognized on these notes for the three and nine months ended September 30, 2023 (in thousands):

The following table sets forth the key terms and fair values of our interest rate swap derivatives (dollars in thousands):

							Fair Value at
Notional Amount			Fixed Rate	Floating Rate Index	Effective Date	Expiration Date	September 30, 2023		December 31, 2022
$	10,700	(1)	1.678%	SOFR + 0.10%	8/1/2019	8/1/2026	$	833	$	806
$	22,550	(2)	0.573%	SOFR + 0.10%	4/1/2020	3/26/2025	1,490		1,825

$	50,000		3.747%	One-Month SOFR	2/1/2023	2/2/2026	1,100		—
							$	6,736	$	2,631

(1)The notional amount of this instrument is scheduled to amortize to $10.0 million.

(2)The notional amount of this instrument is scheduled to amortize to $22.1 million.

Each of these swaps was designated as a cash flow hedge of interest rate risk.

The table below sets forth the fair value of our interest rate derivatives as well as their classification on our consolidated balance sheets (in thousands):

		Fair Value at
Derivatives	Balance Sheet Location	September 30, 2023		December 31, 2022
Interest rate swaps designated as cash flow hedges	Prepaid expenses and other assets, net	$	6,736	$	2,631

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 AOCI on Derivatives								Amount of Income (Loss) Reclassified from AOCI into Interest Expense on Statement of Operations
Derivatives in Hedging Relationships	For the Three Months Ended September 30,				For the Nine Months Ended September 30,				For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2023		2022		2023		2022		2023		2022		2023		2022
Interest rate derivatives	$	2,042	$	1,101	$	6,816	$	4,646	$	1,146	$	77	$	2,711	$	(1,680)

Based on the fair value of our derivatives as of September 30, 2023, we estimate that approximately $4.5 million of gains will be reclassified from accumulated other comprehensive income (“ AOCI”) as a decrease 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 September 30, 2023, we were not in default with any of these provisions. As of September 30, 2023, we did not have any derivatives in liability positions.

10.    Redeemable Noncontrolling Interests

Redeemable noncontrolling interests on our consolidated balance sheets includes the ownership interests of our partners in LW Redstone Company, LLC and Stevens Investors, LLC due to the partners’ rights to require us to acquire their interests. Effective in June 2023, these rights expired for our Stevens Investors, LLC partners, which resulted in our reclassification of their interests from redeemable noncontrolling interests to the noncontrolling interests in subsidiaries section of equity. The table below sets forth the activity for redeemable noncontrolling interests (in thousands):

	For the Nine Months Ended September 30,
	2023		2022
Beginning balance	$	26,293	$	26,898
Distributions to noncontrolling interests	(1,971)		(2,209)
Net income attributable to noncontrolling interests	1,856		2,100
Adjustments for changes in fair value of interests	(1,686)		(1,342)
Reclassification of Stevens Investors, LLC interests to equity	(2,670)		—
Ending balance	$	21,822	$	25,447

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.

11.    Equity

As of September 30, 2023, we had remaining capacity under our at-the-market stock offering program equal to an aggregate gross sales price of $300 million in common shares.

We declared dividends per common share of $0.285 in the three months ended September 30, 2023, $0.275 in the three months ended September 30, 2022, $0.855 in the nine months ended September 30, 2023 and $0.825 in the nine months ended September 30, 2022.

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

12.    Information by Business Segment

We have the following reportable segments: Defense/IT Portfolio, which we referred to as Defense/IT Locations in prior reporting periods; Wholesale Data Center (the only property in which we sold on January 25, 2022); and Other. We also report on Defense/IT Portfolio 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). In the third quarter of 2023, we retrospectively reclassified to our Other reportable segment a portfolio of office properties located in the Greater Washington, DC/Baltimore region that we previously reported as a separate reportable segment referred to as Regional Office.

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 CDP”). 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 September 30,				For the Nine Months Ended September 30,
	2023		2022		2023		2022
Construction contract and other service revenues	$	11,949	$	34,813	$	42,012	$	130,570

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

	September 30, 2023		September 30, 2022
Segment assets	$	3,479,364	$	3,468,618
Operating properties lease liabilities included in segment assets	33,360		29,088

Other assets	402,365		239,785
Total consolidated assets	$	4,239,257	$	4,269,329

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 (loss) 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, leasing and other expenses, interest and other income, net, income taxes and noncontrolling interests because these items represent general corporate or non-operating property items not attributable to segments.

13.    Construction Contract and Other Service Revenues

We disaggregate in the table below our construction contract and other service revenues by compensation arrangement as we believe it best depicts the nature, timing and uncertainty of our revenue (in thousands):

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2023		2022		2023		2022
Construction contract revenue:

	$	11,949	$	34,813	$	42,012	$	130,570

We recognized an insignificant amount of revenue in the three and nine months ended September 30, 2023 and 2022 from performance obligations satisfied (or partially satisfied) in previous periods.

Portion of beginning balance recognized in revenue during:
Three months ended September 30,	$	64	$	14
Nine months ended September 30,	$	164	$	204

Revenue allocated to the remaining performance obligations under existing contracts as of September 30, 2023 that will be recognized as revenue in future periods was $75.7 million, of which we expect to recognize approximately $23 million in the three months ending December 31, 2023 and the remainder in 2024.

We have no deferred incremental costs incurred to obtain or fulfill our construction contracts or other service revenues as of September 30, 2023 and December 31, 2022. Credit loss expense or recoveries on construction contracts receivable and unbilled construction revenue was insignificant for the three and nine months ended September 30, 2023. Credit loss recoveries on construction contracts receivable and unbilled construction revenue was $369,000 and $461,000 for the three and nine months ended September 30, 2022, respectively.

Our investment grade credit risk classification represents entities with investment grade credit ratings from ratings agencies (such as S&P Global Ratings, Moody’s Investors Service, Inc. or Fitch Ratings, Inc.), 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 September 2023.

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 September 30, 2023 and December 31, 2022 were not significant. We did not recognize any interest income on notes receivable on nonaccrual status during the nine months ended September 30, 2023 and 2022.

15.    Share-Based Compensation

Restricted Shares

The following table summarizes restricted share activity under our share-based compensation plans for the nine months ended September 30, 2023:

	Number of Shares	Weighted Average Grant Date Fair Value
Unvested as of December 31, 2022	325,083	$	26.27
Granted	205,836	$	25.37
Forfeited	(34,593)	$	26.03
Vested	(146,611)	$	26.07
Unvested as of September 30, 2023	349,715	$	25.85

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.

The aggregate intrinsic value of restricted shares that vested was $3.7 million for the nine months ended September 30, 2023.

Profit Interest Units in CDPLP (“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

The following table summarizes TB-PIUs activity under our share-based compensation plans for the nine months ended September 30, 2023:

	Number of TB-PIUs	Weighted Average Grant Date Fair Value
Unvested as of December 31, 2022	187,330	$	26.19
Granted	100,426	$	25.37
Forfeited	(27,182)	$	26.46
Vested	(89,633)	$	25.95
Unvested as of September 30, 2023	170,941	$	25.79

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. 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.

The aggregate intrinsic value of TB-PIUs that vested was $2.3 million for the nine months ended September 30, 2023.

25

PB-PIUs

On January 1, 2023, we granted certain senior management team members 275,402 PB-PIUs with a three-year performance period concluding on the earlier of December 31, 2025 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 CDP’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 CDP’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 $4.3 million ($31.54 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 $25.94; expected volatility for common shares of 35.0%; and a risk-free interest rate of 4.28%.  

During the nine months ended September 30, 2023, 126,890 PB-PIUs were forfeited; these PB-PIUs had a weighted average grant date fair value per target-level award of $31.49.

Based on CDP’s TSR relative to its peer group of companies, for the 2020 PB-PIUs issued to executives that vested on December 31, 2022, we issued 141,152 PIUs in settlement of the PB-PIUs on February 1, 2023.

Deferred Share Awards

During the nine months ended September 30, 2023, non-employee Trustees were granted 9,046 deferred share awards with an aggregate grant date fair value of $215,000 ($23.75 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).

16.    Earnings Per Share (“EPS”)

We present both basic and diluted EPS.  We compute basic EPS by dividing net (loss) 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):

Our diluted EPS computations do not include the effects of the following securities since the conversions of such securities would increase diluted EPS for the respective periods (in thousands):

	Weighted Average Shares Excluded from Denominator
	For the Three Months Ended September 30,		For the Nine Months Ended September 30,

Conversion of common units	1,520	1,477	1,508	1,446
Conversion of redeemable noncontrolling interests	882	895	980	855

The following securities were also excluded from the computation of diluted EPS because their effect was antidilutive:

•weighted average restricted shares and deferred share awards for the three months ended September 30, 2023 and 2022 of 423,000 and 399,000, respectively, and for the nine months ended September 30, 2023 and 2022 of 411,000 and 401,000, respectively;

•weighted average TB-PIUs for the three months ended September 30, 2023 and 2022 of 171,000 and 192,000, respectively, and for the nine months ended September 30, 2023 and 2022 of 174,000 and 185,000, respectively;

27

•weighted average vested PIUs for the three and nine months ended September 30, 2023 of 170,000 and 148,000, respectively; and

•weighted average PB-PIUs for the three and nine months ended September 30, 2023 of 608,000 and 636,000, respectively.

As discussed in Note 8, our 5.25% Notes issued on September 12, 2023 have an exchange settlement feature under which the principal amount of notes exchanged is payable in cash, with the remainder of the exchange obligation, if any, as determined based on the exchange price per common share at the time of settlement, payable in cash, common shares or a combination thereof at our election. These notes did not affect our diluted EPS reported above since the weighted average closing price of our common shares for the three and nine months ended September 30, 2023 was less than the exchange price applicable to such periods.

17.    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 September 30, 2023, management believes that it is reasonably possible that we could recognize a loss of up to $4.3 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 operations.  We have performed environmental assessments of our properties, the results of which have not revealed any environmental liability that we believe would have a materially adverse effect on our financial position, operations or liquidity.

In connection with a lease and subsequent sale in 2008 and 2010 of 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 most 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 $27 million as of September 30, 2023. 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 September 30, 2023, 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 nine months ended September 30, 2023, we: 

•finished the period with our portfolio 94.1% occupied and 95.1% leased;

•achieved a tenant retention rate of 82.5%, which was driven by strong leasing demand for space in our Defense/IT Portfolio;

•issued $345.0 million aggregate principal amount of 5.25% Notes in a private placement. The proceeds from this issuance, after deducting the initial purchasers’ commissions, but before other offering expenses, were $336.4 million. The net proceeds from the notes were primarily used for general corporate purposes, including the repayment of borrowings under our Revolver Credit Facility and the pre-funding of future development investments, which resulted in a portion of the net proceeds being invested in short-term interest-bearing money market accounts pending such use; and

•sold a 90% interest in three data center shell properties in Northern Virginia for $190.2 million, resulting in a gain on sale of $49.4 million. We used virtually all of the proceeds to pay down our Revolving Credit Facility to create additional borrowing capacity available to fund future development.

For 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 or loss 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, property operating and 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;

29

•our ability to achieve projected results;

•security breaches relating to cyber attacks, cyber intrusions or other factors, and other significant disruptions of our information technology networks and related systems; 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 nine months ended September 30, 2023, we leased 2.2 million square feet, including: 1.4 million square feet of renewal leasing (representing a tenant retention rate of 82.5%); 495,000 square feet of development leasing; and 337,000 square feet of vacant space 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 and segment analysis. Tenant retention rate is a measure we use that represents the percentage of square feet renewed in a period relative to the total square feet scheduled to expire in that period; we include the effect of early renewals in this measure.

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 the net of revenues and property operating expenses of real estate operations owned through UJVs that is allocable to our ownership interest (“UJV NOI allocable to CDP”). The table below reconciles NOI from real estate operations to net (loss) income, the most directly comparable GAAP measure:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,

Property operating expenses from discontinued operations	—		—		—		(971)
NOI from real estate operations	$	96,494	$	91,096	$	285,421	$	268,494

We view our changes in NOI from real estate operations as being comprised of the following primary categories:

•Same Property, which we define as properties stably owned and 100% operational throughout the current and prior year reporting periods being compared;

•developed or redeveloped properties placed into service that were not 100% operational throughout the current and prior year reporting periods; and

•disposed properties.

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 or loss, 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 12 to our consolidated financial statements.

Our Same Property pool consisted of 180 properties, comprising 87.8% of our portfolio’s square footage as of September 30, 2023. This pool of properties changed from the pool used for purposes of comparing 2022 and 2021 in our 2022 Annual Report on Form 10-K due to the: addition of seven properties placed in service and 100% operational on or before January 1, 2022 and two properties owned through an unconsolidated real estate joint venture that was formed in 2021; and removal of three properties in which we sold a 90% interest in 2023.

33

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

•the increase for our Same Property pool was due in large part to additional revenue in the current period resulting from higher occupancy and the commencement of tenant expense reimbursements on certain recently commenced leases;

•developed and redeveloped properties placed in service reflects the effect of 11 properties placed in service in 2022 and 2023; and

•dispositions, net of retained interest in newly-formed UJVs reflects the effect of our sale of 90% of our interests in three data center shells in 2023 and two in 2022.

NOI from Service Operations

	For the Three Months Ended September 30,
	2023		2022		Variance
	(in thousands)
Construction contract and other service revenues	$	11,949	$	34,813	$	(22,864)
Construction contract and other service expenses	(11,493)		(33,555)		22,062
NOI from service operations	$	456	$	1,258	$	(802)

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

Impairment Losses

As part of our closing process for the three months ended September 30, 2023, we conducted our quarterly review of our portfolio of long-lived assets to be held and used for indicators of impairment. As a result of this process, we shortened the expected holding periods for six operating properties in our Other segment and a parcel of land located in Baltimore, Maryland, Northern Virginia and Washington, D.C. We determined that the carrying amount of the properties would not likely be recovered from the undiscounted cash flows from the operations and sales of the properties over the shortened holding periods. Accordingly, we recognized impairment losses of $252.8 million on these properties during the period.

Interest Expense

Interest expense increased due to higher weighted average variable interest rates in the current period. While our debt is predominantly fixed rate and in the form of long-term unsecured notes, for variable rate loans, we have used interest rate swaps to hedge the effect of interest rate increases on variable rate debt, including swaps for a $200.0 million notional amount that: fixed the one-month LIBOR interest rate in 2022 at 1.9% through December 1, 2022; and, effective February 1, 2023, fixed the one-month SOFR interest rate at 3.7% for a three-year term.

Interest and Other Income, Net

Interest and other income, net increased due in large part to credit losses recognized in the prior period upon our issuance of new investing receivables.

NOI from service operations	$	1,763	$	4,061	$	(2,298)

Construction contract and other service revenue and expenses decreased in the current period due primarily to a lower volume of construction activity for one of our tenants.

Impairment Losses

Refer to our explanation above for the three-month periods.

General, Administrative, Leasing and Other Expenses

General, administrative, leasing and other expenses increased primarily due to higher compensation-related expenses in the current period.

Interest Expense

Refer to our explanation above for the three-month periods.

Interest and Other Income, Net

Refer to our explanation above for the three-month periods.

Gain on Sales of Real Estate

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

Discontinued Operations

Discontinued operations in the prior period relates to our wholesale data center, including $28.6 million in gain from its sale on January 25, 2022.

Funds from Operations

Funds from operations (“FFO”) is defined as net income or loss computed using GAAP, excluding gains on sales and impairment losses of real estate and investments in UJVs (net of associated income tax) and real estate-related depreciation and amortization. FFO also includes adjustments to net income or loss 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 (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 or loss is the most directly comparable GAAP measure to FFO.

Since FFO excludes certain items includable in net income or loss, 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 or loss 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

37

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 or loss 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 or loss 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 (which includes discontinued operations) 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 or loss 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 that secured non-recourse debt on which we defaulted and, subsequently, extinguished, via conveyance of such properties (including property NOI, interest expense and gains on debt extinguishment); loss on interest rate derivatives; executive transition costs associated with named executive officers; and, for periods prior to October 1, 2022, demolition costs on redevelopment and nonrecurring improvements and executive transition costs associated with other senior management team members. 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 or loss 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 or loss 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 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 CDPLP 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 nine months ended September 30, 2023 (in thousands):

Development	$	201,696
Tenant improvements on operating properties (1)	52,001
Capital improvements on operating properties	11,214
	$	264,911

(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 $22.5 million when comparing the nine months ended September 30, 2023 and 2022, which included the effects of increased cash flow from real estate operations resulting from the growth of our operating portfolio, offset in part by higher payments for lease incentives in the current period.

Net cash flow used in investing activities increased $19.4 million when comparing the nine months ended September 30, 2023 and 2022 due in large part to lower proceeds from properties sold in the current period (which included our sale of a 90% interest in three data center shells) relative to the prior period (which included the sale of our wholesale data center) and higher cash outlays for tenant improvements on operating properties in the current period resulting from increased leasing activity.

Net cash flow provided by financing activities in the nine months ended September 30, 2023 was $81.0 million, and included primarily the following:

•net proceeds of debt borrowings during the period of $182.2 million, which included the net effect of our issuance of the 5.25% Notes and a net paydown of borrowings under our Revolving Credit Facility using proceeds from the notes issuance and from property sales; and

•dividends to common shareholders of $95.1 million.

Net cash flow used in financing activities in the nine months ended September 30, 2022 was $105.6 million, and included

dividends to common shareholders of $92.7 million. Net repayments of debt borrowings during the period totaled $5.5 million, which included a $200.0 million term loan repayment using proceeds from the sale of our wholesale data center, mostly offset by net borrowings from our Revolving Credit Facility used primarily to fund development of properties.

Supplemental Guarantor Information

As of September 30, 2023, CDPLP had several series of unsecured senior notes outstanding that were issued in transactions registered with the Securities and Exchange Commission under the Securities Act of 1933, as amended. These notes are CDPLP’s direct, senior unsecured and unsubordinated obligations and rank equally in right of payment with all of CDPLP’s existing and future senior unsecured and unsubordinated indebtedness. However, these notes are effectively subordinated in right of payment to CDPLP’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 CDPLP's subsidiaries. CDP fully and unconditionally guarantees CDPLP’s obligations under these notes. CDP’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, CDP. CDP itself does not hold any indebtedness, and its only material asset is its investment in CDPLP.

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 September 30, 2023, we had $204.2 million in cash and cash equivalents. We were carrying a significant amount of cash and cash equivalents as of the end of the period due to our use of a portion of the net proceeds from our issuance of the 5.25% Notes to pre-fund future development investments, which resulted in a portion of the net proceeds being invested in short-term interest-bearing money market accounts pending such use.

We have a Revolving Credit Facility with a maximum borrowing capacity of $600.0 million. 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 October 2026 and may be extended by two six-month periods at our option, provided that there is no default under the facility

40

and we pay an extension fee of 0.0625% of the total availability under the facility for each extension period. Our available borrowing capacity under the facility totaled $525.0 million as of September 30, 2023.

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.

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, administrative and leasing expenses;

•debt service, including interest expense;

•property development/redevelopment costs;

•tenant and capital improvements and leasing costs for operating properties (expected to total approximately $35 million during the remainder of 2023);

•debt balloon payments due upon maturity; and

•dividends to our shareholders.

We expect to use cash flow from operations during the remainder of 2023 and annually thereafter for the foreseeable future to fund all of these cash requirements except for debt balloon payments due upon maturity and a portion of property development/redevelopment costs, the fundings for which are discussed below.

During the remainder of 2023, we expect to spend approximately $60 million on development costs, most of which was contractually obligated as of September 30, 2023; we expect to fund these cash requirements using, in part, remaining cash flow from operations, with the balance funded using excess available cash and cash equivalents. We have no debt balloon payments for the remainder of 2023.

Beyond 2023, we expect to continue to actively develop and redevelop properties and fund using, in part, remaining cash flow from operations and any remaining excess available cash and cash equivalents, with the balance, at least initially, funded primarily 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 8.

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 September 30, 2023, 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 to the extent we do not have interest rate swaps in place to hedge the effect of such rate increases.  Increases in interest rates can also result in increased interest expense when our fixed rate debt matures and needs to be refinanced.

41

The following table sets forth as of September 30, 2023 our debt obligations and weighted average interest rates on debt maturing each year (dollars in thousands):

	For the Periods Ending December 31,
	2023		2024		2025		2026		2027		Thereafter		Total
Debt:
Fixed rate debt (1)	$	628	$	29,443	$	1,302	$	436,140	$	—	$	1,745,000	$	2,212,513
Weighted average interest rate	3.84%		4.42%		3.23%		2.38%		—%		3.11%		2.98%
Variable rate debt (2)	$	135	$	540	$	22,415	$	210,160	$	—	$	—	$	233,250
Weighted average interest rate (3)	6.91%		6.91%		6.95%		6.65%		—%		—%		6.68%

(1)Represents principal maturities only and therefore excludes net discounts and deferred financing costs of $30.0 million.

(2)As of September 30, 2023, maturities in 2026 included $75.0 million that may be extended to 2027 and $125.0 million that may be extended to 2028, both subject to certain conditions.

(3)The amounts reflected above used interest rates as of September 30, 2023 for variable rate debt.

The fair value of our debt was $2.1 billion as of September 30, 2023.  If interest rates had been 1% lower, the fair value of our fixed-rate debt would have increased by approximately $78 million as of September 30, 2023.

See Note 9 to our consolidated financial statements for information pertaining to interest rate swap contracts in place as of September 30, 2023 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 $764,000 in the nine months ended September 30, 2023 if the applicable variable index 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 September 30, 2023.  Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of September 30, 2023 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

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization

Organization

COPT Defense Properties (“CDP”) and subsidiaries (collectively, the “Company”, “we” or “us”) is a fully-integrated and self-managed real estate investment trust (“REIT”) focused on owning, operating and developing properties in locations proximate to, or sometimes containing, key U.S. Government (“USG”) defense installations and missions (which we refer to herein as our Defense/IT Portfolio). Our tenants include the USG and their defense contractors, who are primarily engaged in priority national security activities, and who generally require mission-critical and high security property enhancements. In September 2023, we changed our name from Corporate Office Properties Trust to COPT Defense Properties to better describe our investment strategy’s focus on locations serving our country’s priority defense activities. As of September 30, 2023, our Defense/IT Portfolio included:

•188 operating properties totaling 21.3 million square feet comprised of 15.8 million square feet in 159 office properties and 5.5 million square feet in 29 single-tenant data center shells. We owned 24 of these data center shells through unconsolidated real estate joint ventures;

•six properties under development (three office properties and three data center shells) that will total approximately 971,000 square feet upon completion; and

•approximately 670 acres of land controlled that we believe could be developed into approximately 8.1 million square feet.

We also owned eight other operating properties totaling 2.1 million square feet and approximately 50 acres of other developable land in the Greater Washington, DC/Baltimore region as of September 30, 2023.

We conduct almost all of our operations and own almost all of our assets through our operating partnership, COPT Defense Properties, L.P. (“CDPLP”) and subsidiaries (collectively, the “Operating Partnership”), of which CDP is the sole general partner. CDPLP owns real estate directly and through subsidiary partnerships and limited liability companies (“LLCs”).  In addition to owning real estate, CDPLP 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”). In September 2023, we changed CDPLP’s name from Corporate Office Properties, L.P. to COPT Defense Properties, L.P.

Equity interests in CDPLP are in the form of common and preferred units. As of September 30, 2023, CDP owned 97.9% of the outstanding CDPLP common units (“common units”) and there were no preferred units outstanding. Common units not owned by CDP carry certain redemption rights. The number of common units owned by CDP is equivalent to the number of outstanding common shares of beneficial interest (“common shares”) of CDP, and the entitlement of common units to quarterly distributions and payments in liquidation is substantially the same as that of CDP common shareholders.

In September 2023, the ticker symbol under which our common shares are publicly traded on the New York Stock Exchange (“NYSE”) changed from “OFC” to “CDP”.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation

These consolidated financial statements include the accounts of CDP, the Operating Partnership, their subsidiaries and other entities in which CDP 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, 2022 included in our 2022 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 2022 Annual Report on Form 10-K.

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.

Fair Value Disclosures [Abstract]

Fair Value Measurements

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 of mutual funds) 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. The balance of the plan, which was fully funded and totaled $1.7 million as of September 30, 2023, is included in the line entitled “prepaid expenses and other assets, net” on our consolidated balance sheets. 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, as disclosed in Note 9, 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 September 30, 2023, 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 8, 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. 

The table below sets forth our financial assets and liabilities accounted for at fair value on a recurring basis as of September 30, 2023 and the hierarchy level of inputs used in measuring their respective fair values under applicable accounting standards (in thousands):

Description	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable  Inputs (Level 3)		Total

Nonrecurring Fair Value Measurements

As part of our closing process for the three months ended September 30, 2023, we conducted our quarterly review of our portfolio of long-lived assets to be held and used for indicators of impairment. As a result of this process, we shortened the expected holding periods for six operating properties in our Other segment and a parcel of land located in Baltimore, Maryland, Northern Virginia and Washington, D.C. We determined that the carrying amount of the properties would not likely be recovered from the undiscounted cash flows from the operations and sales of the properties over the shortened holding periods. Accordingly, we recognized impairment losses of $252.8 million on these properties during the period. The combined fair value of these properties as of September 30, 2023 was $311.3 million, as determined using significant unobservable inputs (Level 3 of the fair value hierarchy).

The table below sets forth quantitative information about significant unobservable inputs used for the Level 3 fair value measurements reported above as of September 30, 2023 (dollars in thousands):

Valuation Technique	Fair Values on Measurement Date		Unobservable Input	Range (Weighted Average (1))
Discounted cash flow (2)	$	257,800	Terminal capitalization rate	6.5% - 9.5% (8.0%)
			Discount rate	7.5% - 10.5% (9.0%)
Comparable sales price (3)	$	53,500	Comparable sales price	N/A

(1)Weighted average calculation based on relative fair value.

(2)This technique was used for the operating properties in Baltimore, Maryland and Washington, D.C. For the properties in Baltimore, Maryland, the terminal capitalization rate was 9.5% and the discount rate was 10.5%. For the property in Washington, D.C., the terminal capitalization rate was 6.5% and the discount rate was 7.5%.

(3)This technique was used for the operating properties in Northern Virginia and a parcel of land in Baltimore, Maryland.

We lease real estate properties, comprised primarily of office properties and data center shells, to third parties. These leases encompass all, or a portion, of properties, with various expiration dates. Our lease revenue is comprised of: fixed lease revenue, including contractual rent billings under leases recognized on a straight-line basis over lease terms and amortization of lease incentives and above- and below- market lease intangibles; and variable lease revenue, including tenant expense recoveries, lease termination revenue and other revenue from tenants that is not fixed under leases.

(2)Our investment in B RE COPT DC JV II LLC was lower than our share of the joint venture’s equity by $6.9 million as of September 30, 2023 and $7.0 million as of December 31, 2022 due to a difference between our cost basis and our share of the joint venture’s underlying equity in its net assets. We recognize adjustments to our share of the joint venture’s earnings and losses resulting from this basis difference in the underlying assets of the joint venture.

As described further in Note 4, on January 10, 2023, we sold a 90% interest in three data center shell properties in Northern Virginia and retained a 10% interest in the properties through Redshift JV LLC, a newly-formed joint venture. We concluded that the joint venture is a variable interest entity. Under the terms of the joint venture agreement, we and our partner receive returns in proportion to our investments, and our maximum exposure to losses is limited to our investment, subject to our share of certain indemnification obligations with respect to nonrecourse debt secured by the properties. The nature of our involvement in the activities of the joint venture does not give us power over decisions that significantly affect its economic performance.

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

On September 12, 2023, we issued $345.0 million aggregate principal amount of 5.25% Exchangeable Senior Notes due 2028 (the “5.25% Notes”) in a private placement. The proceeds from this issuance, after deducting the initial purchasers’ commissions, but before other offering expenses, were $336.4 million. The notes bear interest at a rate of 5.25% per year, payable semi-annually in arrears on March 15 and September 15 of each year, beginning on March 15, 2024. The notes mature on September 15, 2028 unless earlier exchanged, redeemed or repurchased.

Prior to the close of business on the business day immediately preceding June 15, 2028, the notes will be exchangeable at the option of the noteholders only in the event of certain circumstances and during certain periods defined under the terms of the

notes. On or after June 15, 2028, the notes will be exchangeable at the option of the holders at any time prior to the close of business on the business day immediately preceding the maturity date. Upon exchange, the principal amount of notes is payable in cash. The remainder of the exchange obligation, if any, as determined based on the exchange price per common share at the time of settlement, is payable in cash, common shares or a combination thereof at our election. The exchange rate of the notes initially equaled 33.3739 of our common shares per $1,000 principal amount of notes (equivalent to an initial exchange price of approximately $29.96 per common share). The exchange rate is subject to adjustment upon the occurrence of some events, but will not be adjusted for any accrued and unpaid interest.

We may redeem the notes at our option, in whole or in part, on any business day on or after September 21, 2026, and prior to the 51st scheduled trading day immediately preceding the maturity date, if the last reported sale price of our common shares has been at least 130% of the exchange price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. The redemption price will be equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

These notes are unconditionally guaranteed by CDP. The table below sets forth interest expense recognized on these notes for the three and nine months ended September 30, 2023 (in thousands):

Interest expense at stated interest rate	$	956
Interest expense associated with amortization of debt discount and issuance costs	124

Based on the fair value of our derivatives as of September 30, 2023, we estimate that approximately $4.5 million of gains will be reclassified from accumulated other comprehensive income (“ AOCI”) as a decrease 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 September 30, 2023, we were not in default with any of these provisions. As of September 30, 2023, we did not have any derivatives in liability positions.

Noncontrolling Interest [Abstract]

Redeemable Noncontrolling Interests

Redeemable Noncontrolling Interests

Redeemable noncontrolling interests on our consolidated balance sheets includes the ownership interests of our partners in LW Redstone Company, LLC and Stevens Investors, LLC due to the partners’ rights to require us to acquire their interests. Effective in June 2023, these rights expired for our Stevens Investors, LLC partners, which resulted in our reclassification of their interests from redeemable noncontrolling interests to the noncontrolling interests in subsidiaries section of equity. The table below sets forth the activity for redeemable noncontrolling interests (in thousands):

	For the Nine Months Ended September 30,
	2023		2022
Beginning balance	$	26,293	$	26,898

Reclassification of Stevens Investors, LLC interests to equity	(2,670)		—
Ending balance	$	21,822	$	25,447

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.

Segment Reporting [Abstract]

Information by Business Segment

Information by Business SegmentWe have the following reportable segments: Defense/IT Portfolio, which we referred to as Defense/IT Locations in prior reporting periods; Wholesale Data Center (the only property in which we sold on January 25, 2022); and Other. We also report on Defense/IT Portfolio 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). In the third quarter of 2023, we retrospectively reclassified to our Other reportable segment a portfolio of office properties located in the Greater Washington, DC/Baltimore region that we previously reported as a separate reportable segment referred to as Regional Office.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 CDP”). 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 September 30,				For the Nine Months Ended September 30,
	2023		2022		2023		2022

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 (loss) 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, leasing and other expenses, interest and other income, net, 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 September 30, 2023 that will be recognized as revenue in future periods was $75.7 million, of which we expect to recognize approximately $23 million in the three months ending December 31, 2023 and the remainder in 2024.

We have no deferred incremental costs incurred to obtain or fulfill our construction contracts or other service revenues as of September 30, 2023 and December 31, 2022. Credit loss expense or recoveries on construction contracts receivable and unbilled construction revenue was insignificant for the three and nine months ended September 30, 2023. Credit loss recoveries on construction contracts receivable and unbilled construction revenue was $369,000 and $461,000 for the three and nine months ended September 30, 2022, respectively.

Our investment grade credit risk classification represents entities with investment grade credit ratings from ratings agencies (such as S&P Global Ratings, Moody’s Investors Service, Inc. or Fitch Ratings, Inc.), 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 September 2023.

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 September 30, 2023 and December 31, 2022 were not significant. We did not recognize any interest income on notes receivable on nonaccrual status during the nine months ended September 30, 2023 and 2022.

Share-Based Compensation

Restricted Shares

The following table summarizes restricted share activity under our share-based compensation plans for the nine months ended September 30, 2023:

	Number of Shares	Weighted Average Grant Date Fair Value
Unvested as of December 31, 2022	325,083	$	26.27
Granted	205,836	$	25.37
Forfeited	(34,593)	$	26.03
Vested	(146,611)	$	26.07
Unvested as of September 30, 2023	349,715	$	25.85

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.

The aggregate intrinsic value of restricted shares that vested was $3.7 million for the nine months ended September 30, 2023.

Profit Interest Units in CDPLP (“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

The following table summarizes TB-PIUs activity under our share-based compensation plans for the nine months ended September 30, 2023:

	Number of TB-PIUs	Weighted Average Grant Date Fair Value
Unvested as of December 31, 2022	187,330	$	26.19
Granted	100,426	$	25.37
Forfeited	(27,182)	$	26.46
Vested	(89,633)	$	25.95
Unvested as of September 30, 2023	170,941	$	25.79

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. 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.

The aggregate intrinsic value of TB-PIUs that vested was $2.3 million for the nine months ended September 30, 2023.

PB-PIUs

On January 1, 2023, we granted certain senior management team members 275,402 PB-PIUs with a three-year performance period concluding on the earlier of December 31, 2025 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 CDP’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 CDP’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 $4.3 million ($31.54 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 $25.94; expected volatility for common shares of 35.0%; and a risk-free interest rate of 4.28%.  

During the nine months ended September 30, 2023, 126,890 PB-PIUs were forfeited; these PB-PIUs had a weighted average grant date fair value per target-level award of $31.49.

Based on CDP’s TSR relative to its peer group of companies, for the 2020 PB-PIUs issued to executives that vested on December 31, 2022, we issued 141,152 PIUs in settlement of the PB-PIUs on February 1, 2023.

Deferred Share Awards

During the nine months ended September 30, 2023, non-employee Trustees were granted 9,046 deferred share awards with an aggregate grant date fair value of $215,000 ($23.75 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).

Earnings Per Share [Abstract]

Earnings Per Share (“EPS”)

Earnings Per Share (“EPS”)

We present both basic and diluted EPS.  We compute basic EPS by dividing net (loss) 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):

Net (loss) income	$	(1.94)	$	0.27	$	(0.96)	$	1.08

Our diluted EPS computations do not include the effects of the following securities since the conversions of such securities would increase diluted EPS for the respective periods (in thousands):

	Weighted Average Shares Excluded from Denominator
	For the Three Months Ended September 30,		For the Nine Months Ended September 30,
	2023	2022	2023	2022
Conversion of common units	1,520	1,477	1,508	1,446
Conversion of redeemable noncontrolling interests	882	895	980	855

The following securities were also excluded from the computation of diluted EPS because their effect was antidilutive:

•weighted average restricted shares and deferred share awards for the three months ended September 30, 2023 and 2022 of 423,000 and 399,000, respectively, and for the nine months ended September 30, 2023 and 2022 of 411,000 and 401,000, respectively;

•weighted average TB-PIUs for the three months ended September 30, 2023 and 2022 of 171,000 and 192,000, respectively, and for the nine months ended September 30, 2023 and 2022 of 174,000 and 185,000, respectively;

•weighted average vested PIUs for the three and nine months ended September 30, 2023 of 170,000 and 148,000, respectively; and

•weighted average PB-PIUs for the three and nine months ended September 30, 2023 of 608,000 and 636,000, respectively.

As discussed in Note 8, our 5.25% Notes issued on September 12, 2023 have an exchange settlement feature under which the principal amount of notes exchanged is payable in cash, with the remainder of the exchange obligation, if any, as determined based on the exchange price per common share at the time of settlement, payable in cash, common shares or a combination thereof at our election. These notes did not affect our diluted EPS reported above since the weighted average closing price of our common shares for the three and nine months ended September 30, 2023 was less than the exchange price applicable to such periods.

Commitments and Contingencies

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 September 30, 2023, management believes that it is reasonably possible that we could recognize a loss of up to $4.3 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 operations.  We have performed environmental assessments of our properties, the results of which have not revealed any environmental liability that we believe would have a materially adverse effect on our financial position, operations or liquidity.

In connection with a lease and subsequent sale in 2008 and 2010 of 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 most 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 $27 million as of September 30, 2023. 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 September 30, 2023, we do not expect any such future fundings will be required.

Summary of Significant Accounting Policies (Policies)

Sep. 30, 2023

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

These consolidated financial statements include the accounts of CDP, the Operating Partnership, their subsidiaries and other entities in which CDP 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, 2022 included in our 2022 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 2022 Annual Report on Form 10-K.

Reclassifications

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.
