~~Securities registered pursuant to Section 12(b) of the Act:~~



~~Title of each class~~	~~Trading Symbol(s)~~	~~Name of each exchange on which registered~~
~~Common Shares of beneficial interest, $0.01 par value~~	~~OFC~~	~~New York Stock Exchange~~

As of ~~April 26,~~October 25, 2019, ~~111,917,479~~112,058,925 of Corporate Office Properties Trust’s Common Shares of Beneficial Interest, $0.01 par value, were issued and outstanding.

This report combines the quarterly reports on Form 10-Q for the period ended ~~March 31,~~September 30, 2019 of Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company”) and Corporate Office Properties, L.P. (“COPLP”) and subsidiaries (collectively, the “Operating Partnership”). Unless stated otherwise or the context otherwise requires, “we,” “our,” and “us” refer collectively to COPT, COPLP and their subsidiaries.

COPT is a real estate investment trust, or REIT, and the sole general partner of COPLP. As of ~~March 31,~~September 30, 2019, COPT owned ~~98.6%~~98.7% of the outstanding common units in COPLP; the remaining common units and all of the outstanding COPLP preferred units were owned by third parties. As the sole general partner of COPLP, COPT controls COPLP and can cause it to enter into major transactions including acquisitions, dispositions and refinancings and cause changes in its line of business, capital structure and distribution policies.

There are a few differences between the Company and the Operating Partnership which are reflected in this Form 10-Q. We believe it is important to understand the differences between the Company and the Operating Partnership in the context of how the two operate as an interrelated, consolidated company. COPT is a REIT whose only material asset is its ownership of partnership interests of COPLP. As a result, COPT does not conduct business itself, other than acting as the sole general partner of COPLP, issuing public equity and guaranteeing certain debt of COPLP. COPT itself is not directly obligated under any indebtedness but guarantees some of the debt of COPLP. COPLP owns substantially all of the assets of COPT either directly or through its subsidiaries, conducts almost all of the operations of the business and is structured as a limited partnership with no publicly traded equity. Except for net proceeds from public equity issuances by COPT, which are contributed to COPLP in exchange for partnership units, COPLP generates the capital required by COPT’s business through COPLP’s operations, by COPLP’s direct or indirect incurrence of indebtedness or through the issuance of partnership units.

Noncontrolling interests, shareholders’ equity and partners’ capital are the main areas of difference between the consolidated financial statements of COPT and those of COPLP. The common limited partnership interests in COPLP not

owned by COPT are accounted for as partners’ capital in COPLP’s consolidated financial statements and as noncontrolling interests in COPT’s consolidated financial statements. COPLP’s consolidated financial statements also reflect COPT’s noncontrolling interests in certain real estate partnerships and limited liability companies (“LLCs”); the differences between shareholders’ equity, partners’ capital and noncontrolling interests result from the differences in the equity issued at the COPT and COPLP levels and in COPT’s noncontrolling interests in these real estate partnerships and LLCs. The only other

significant differences between the consolidated financial statements of COPT and those of COPLP are assets in connection with a non-qualified elective deferred compensation plan and the corresponding liability to the plan’s participants that are held directly by COPT.

We believe combining the quarterly reports on Form 10-Q of the Company and the Operating Partnership into this single report results in the following benefits:

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

This report also includes separate sections under Part I, Item 4. Controls and Procedures and separate Exhibit 31 and Exhibit 32 certifications for each of COPT and COPLP to establish that the Chief Executive Officer and the Chief Financial Officer of each entity have made the requisite certifications and that COPT and COPLP are compliant with Rule 13a-15 and Rule 15d-14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and 18 U.S.C. §1350.

1. Organization

Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company”) is a fully-integrated and self-managed real estate investment trust (“REIT”). Corporate Office Properties, L.P. (“COPLP”) and subsidiaries (collectively, the “Operating Partnership”) is the entity through which COPT, the sole general partner of COPLP, conducts almost all of its operations and owns almost all of its assets. Unless otherwise expressly stated or the context otherwise requires, “we”, “us” and “our” as used herein refer to each of the Company and the Operating Partnership. We own, manage, lease, develop and selectively acquire office and data center properties. The majority of our portfolio is in locations that support the United States Government and its contractors, most of whom are engaged in national security, defense and information technology (“IT”) related activities servicing what we believe are growing, durable, priority missions (“Defense/IT Locations”). We also own a portfolio of office properties located in select urban/urban-like submarkets in the Greater Washington, DC/Baltimore region

with durable Class-A office fundamentals and characteristics (“Regional Office”). As of ~~March 31,~~September 30, 2019, our properties included the following:

~~165~~169 properties totaling ~~18.3~~19.0 million square feet comprised of ~~15.2~~15.3 million square feet in ~~146~~147 office properties and ~~3.1~~3.7 million square feet in 1922 single-tenant data center shell properties (“data center shells”). We owned ~~six~~13 of these data center shells through an unconsolidated real estate joint ~~venture;~~ventures;

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

15 properties under construction or redevelopment ~~(ten~~(10 office properties and ~~five~~5 data center shells) that we estimate will total approximately ~~2.0~~2.6 million square feet upon completion, including ~~two~~2 partially-operational properties; and

approximately 900 acres of land controlled for future development that we believe could be developed into approximately ~~11.6~~11.2 million square feet and 150 acres of other land.

COPLP owns real estate directly and through subsidiary partnerships and limited liability companies (“LLCs”). In addition to owning real estate, COPLP also owns subsidiaries that provide real estate services such as property management and construction and development services primarily for our properties but also for third parties. Some of these services are performed by a taxable REIT subsidiary (“TRS”).

Equity interests in COPLP are in the form of common and preferred units. As of ~~March 31,~~September 30, 2019, COPT owned ~~98.6%~~98.7% of the outstanding COPLP common units (“common units”); the remaining common units and all of the outstanding COPLP preferred units (“preferred units”) were owned by third parties. Common units not owned by COPT carry certain redemption rights. The number of common units owned by COPT is equivalent to the number of outstanding common shares of beneficial interest (“common shares”) of COPT, and the entitlement of common units to quarterly distributions and payments in liquidation is substantially the same as those of COPT common shareholders. However, COPLP’s common units include a special class of unit referred to as profit interest units (“PIUs”) originating from certain share-based compensation awards issued to executives (described further in Note 15) that are subject to vesting and certain tax event criteria, and accordingly may carry different rights to redemption and distributions than non-PIU common units. COPT’s common shares are publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “OFC”.

Because COPLP is managed by COPT, and COPT conducts substantially all of its operations through COPLP, we refer to COPT’s executive officers as COPLP’s executive officers; similarly, although COPLP does not have a board of trustees, we refer to COPT’s Board of Trustees as COPLP’s Board of Trustees.

2.Summary of Significant Accounting Policies

Basis of Presentation

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

We use the equity method of accounting when we own an interest in an entity and can exert significant influence over but cannot control the entity’s operations. We discontinue equity method accounting if our investment in an entity (and net 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, 2018 included in our 2018 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 2018 Annual Report on Form 10-K as updated for our adoption of recent accounting pronouncements discussed below.

Reclassification

We reclassified certain amounts from prior periods to conform to the current period presentation of our consolidated financial statements with no effect on previously reported net income or equity, including reclassifications of our revenue from real estate operations in connection with our adoption of new lease guidance described below.

Recent Accounting Pronouncements

In February 2016, the FASB issued guidance setting forth principles for the recognition, measurement, presentation and disclosure of leases. This guidance requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. The resulting classification determines whether the lease expense is recognized based on an effective interest method or straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. This guidance requires lessors of real estate to account for leases using an approach substantially equivalent to guidance previously in place for operating leases, direct financing leases and sales-type leases. We adopted this guidance on January 1, 2019 using a modified retrospective transition approach under which we elected to apply the guidance effective January 1, 2019 and not adjust prior comparative reporting periods (except for our presentation of lease revenue discussed below). We elected to apply a package of practical expedients that enabled us to carry forward upon adoption our historical assessments of: expired or existing leases regarding their lease classification and deferred recognition of non-incremental direct leasing costs; and whether any expired or existing contracts are, or contain, leases. We also elected a practical expedient that enabled us to avoid the need to assess whether expired or existing land easements not previously accounted for as leases are, or contain, a lease. In addition, we elected a practical expedient for our rental properties (as lessor) to avoid separating non-lease components that otherwise would need to be accounted for under the recently-adopted revenue accounting guidance (such as tenant reimbursements of property operating expenses) from the associated lease component since (1) the non-lease components have the same timing and pattern of transfer as the associated lease component and (2) the lease component, if accounted for separately, would be classified as an operating lease; this enables us to account for the combination of the lease component and non-lease components as an operating lease since the lease component is the predominant component of the combined components. Below is a summary of the primary changes in our accounting and reporting that resulted from our adoption of this guidance:

Property leases in which we are the lessor:


◦	Deferral of non-incremental leasing costs: For new or extended tenant leases, we no longer defer recognition of non-incremental leasing costs that we would have deferred under prior accounting guidance (refer to our 2018 Annual Report on Form 10-K in which we reported amounts deferred in 2018, 2017 and 2016).

◦

Change in presentation of revenue: Due to our adoption of the practical expedient discussed above to not separate non-lease component revenue from the associated lease component, we are aggregating revenue from our lease components and non-lease components (comprised predominantly of tenant operating expense reimbursements) into the line entitled “lease revenue.” We are reporting other revenue from our properties in the line entitled “other property revenue.” We recast prior periods for these changes in presentation.


◦	Changes in assessment of lease revenue collectability: Changes in our assessment of lease revenue collectability that previously would have resulted in charges to bad debt expense under prior guidance are being recognized as an

adjustment to rental revenue under the new guidance. Such amounts recognized by us in prior periods were not significant.


◦	Operating expenses paid directly by tenants to third parties: Operating expenses paid directly by tenants to third parties (primarily for real estate taxes) and revenue associated with such tenant payments that would have been recognized under prior guidance will no longer be reported on our Statement of Operations. Such amounts recognized by us in prior periods were not significant.

Leases (the most significant of which are ground leases) in which we are the lessee:

◦

Balance sheet presentation of property operating lease right-of-use assets: Upon adoption on January 1, 2019, we recognized property right-of-use assets and offsetting lease liabilities for existing operating leases totaling $16 million for the present value of minimum lease payments under these leases, and also reclassified an additional $11 million in amounts previously presented elsewhere on our balance sheet in connection with these leases to the right-of-use assets. We will recognize additional right-of-use assets and lease liabilities as we enter into new operating leases.

◦

Balance sheet presentation of property finance lease right-of-use assets: Property right-of-use assets of finance leases that previously were presented as properties under prior guidance are being presented as property finance right-of-use assets under the new guidance. As a result, we reclassified $38 million in assets from properties to property finance right-of-use assets upon adoption on January 1, 2019.


◦	Segment assets: We changed our definition of segment assets used for our reportable segments to include property right-of-use assets associated with operating properties, net of related lease liabilities.

In June 2016, the FASB issued guidance that changes how entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the current incurred loss model with an expected loss approach, resulting in a more timely recognition of such losses. The guidance will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities, net investments in leases and off-balance-sheet credit exposures (e.g. loan commitments). Under the new guidance, an entity will recognize its estimate of expected credit losses as an allowance, as the guidance requires that financial assets be measured on an amortized cost basis and to be presented at the net amount expected to be collected. The guidance is effective for us beginning January 1, 2020, with early adoption permitted after December 2018. We are currently assessing the financial impact of this guidance on our consolidated financial statements.

In August 2018, the FASB issued guidance that modifies disclosure requirements for fair value measurements. This guidance is effective for us beginning January 1, 2020. Early adoption is permitted for this guidance, and entities are permitted to early adopt with respect to any removed or modified disclosures while delaying adoption of additional disclosure requirements until the effective date. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

In August 2018, the FASB issued guidance that aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. FASB guidance did not previously address the accounting for such implementation costs. The guidance is effective for us beginning January 1, 2020, with early adoption permitted. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

3.Fair Value Measurements

Recurring Fair Value Measurements

COPT has a non-qualified elective deferred compensation plan for Trustees and certain members of our management team that permits participants to defer up to 100% of their compensation on a pre-tax basis and receive a tax-deferred return on such deferrals. The assets held in the plan (comprised primarily of mutual funds and equity securities) and the corresponding liability to the participants are measured at fair value on a recurring basis on COPT’s consolidated balance sheets using quoted market prices, as are other marketable securities that we hold. The balance of the plan, which was fully funded, totaled ~~$4.2~~$4.3 million as of ~~March 31,~~September 30, 2019, and is included in the line entitled “prepaid expenses and other assets, net” on COPT’s 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~~included in ~~other liabilities~~the line entitled “other liabilities” on COPT’s consolidated balance sheets. The assets of the plan are classified in Level 1 of the fair value hierarchy, while the offsetting liability is classified in Level 2 of the fair value hierarchy.

The fair values of our interest rate derivatives are determined using widely accepted valuation techniques, including a discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate market data and

implied volatilities in such interest rates. While we determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our interest rate derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default. However, as of ~~March 31,~~September 30, 2019, we assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivatives and determined that these adjustments are not significant. As a result, we determined that our interest rate derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

The carrying values of cash and cash equivalents, restricted cash, accounts receivable, other assets (excluding investing receivables) and accounts payable and accrued expenses are reasonable estimates of their fair values because of the short maturities of these instruments. The fair values of our investing receivables, as disclosed in Note 7, were based on the discounted estimated future cash flows of the loans (categorized within Level 3 of the fair value hierarchy); the discount rates used approximate current market rates for loans with similar maturities and credit quality, and the estimated cash payments include scheduled principal and interest payments. For our disclosure of debt fair values in Note 9, we estimated the fair values of our unsecured senior notes based on quoted market rates for publicly-traded debt (categorized within Level 2 of the fair value hierarchy) and estimated the fair value of our other debt based on the discounted estimated future cash payments to be made on such debt (categorized within Level 3 of the fair value hierarchy); the discount rates used approximate current market rates for loans, or groups of loans, with similar maturities and credit quality, and the estimated future payments include scheduled principal and interest payments. Fair value estimates are made as of a specific point in time, are subjective in nature and involve uncertainties and matters of significant judgment. Settlement at such fair value amounts may not be possible and may not be a prudent management decision.

For additional fair value information, please refer to Note 7 for investing receivables, Note 9 for debt and Note 10 for interest rate derivatives.

On June 20, 2019, through a series of transactions, we sold a 90% interest in 7 data center shell properties in Virginia based on an aggregate property value of $265.0 million and retained a 10% interest in the properties through BREIT COPT DC JV LLC (“BREIT-COPT”), a newly-formed joint venture. Our partner in the joint venture acquired the 90% interest from us for $238.5 million. We account for our interest in the joint venture using the equity method of accounting as described further in Note 6. We recognized a gain on sale of $84.5 million.

2019 Construction Activities

During the ~~three~~nine months ended ~~March 31,~~ September 30, 2019, we placed into service ~~181,000~~794,000 square feet in ~~three~~7 newly-constructed properties (including ~~one~~1 partially-operational property). and 10,000 in 1 partially-operational property under redevelopment. As of ~~March 31,~~September 30, 2019, we had 14 properties under construction (including ~~two~~1 partially-operational ~~properties)~~property), or which we were contractually committed to construct, that we estimate will total ~~1.9~~2.5 million square feet upon completion and ~~one~~1 partially-operational property under redevelopment that we estimate will total 106,000 square feet upon completion.

We lease real estate properties, comprised primarily of office properties and data center shells, to third parties. As of ~~March 31,~~September 30, 2019, these leases, which may encompass all, or a portion of, a property, had remaining ~~lease~~ terms spanning from one month to 15 years and averaging approximately five years. These leases usually include options under which the tenant may renew its lease based on market rates at the time of renewal, which are then typically subject to further negotiation. These leases occasionally provide the tenant with an option to terminate its lease early usually for a defined termination fee. While a significant portion of our portfolio is leased to the United States Government, and the majority of those leases consist of a series of one-year renewal options, or provide for early termination rights, we have concluded that exercise of existing renewal options, or continuation of such leases without exercising early termination rights, is reasonably assured for virtually all of these leases.

Most of our lease revenue is from fixed contractual payments defined under the lease that, in most cases, escalate annually over the term of the lease. Our lease revenue also includes variable lease payments predominantly for tenant reimbursements of property operating expenses and lease termination fees. Property operating expense reimbursement structures vary, with some tenants responsible for all of a property’s expenses, while others are responsible for their share of a property’s expense only to the extent such expenses exceed amounts defined in the lease (which are derived from the property’s historical expense levels). Lease termination fees in most cases result from a tenant’s exercise of an existing right under a lease, and are usually equal to a defined percentage of the remaining rents due under the lease and/or the remaining unamortized lease origination costs (including tenant improvements and lease commissions).

The table below sets forth our allocation of lease revenue recognized between fixed contractual payments and variable lease payments (in thousands):



Lease revenue	For the Three Months Ended September 30, 2019		For the Nine Months Ended September 30, 2019

(1) As of ~~March 31,~~September 30, 2019, represents the ~~nine~~three months ending December 31, 2019.

We lease from third parties land underlying certain properties that we are operating or developing. These ground leases have long durations with remaining terms ranging from 30 years (excluding extension options) to 97 years. As of ~~March 31,~~September 30, 2019, our balance sheet included ~~$68.1~~$67.8 million in right-of-use assets associated with ground leases that included:

As of ~~March 31,~~September 30, 2019, our balance sheet also included right-of-use lease assets totaling $1.2 million in connection with vehicles and office equipment that we lease from third parties.

In determining operating right-of-use assets and lease liabilities for our existing operating leases upon our adoption of the new lease guidance discussed further in Note 2, as well as for new operating leases in the current period, we were required to

estimate an appropriate incremental borrowing rate on a fully-collateralized basis for the terms of the leases. Since the terms under our ground leases are significantly longer than the terms of borrowings available to us on a fully-collateralized basis, our estimate of this rate required significant judgment, and considered factors such as interest rates available to us on a fully-collateralized basis for shorter-termed debt and U.S. Treasury rates.

Our right-of-use assets consisted of the following (in thousands):

Lease liabilities consisted of the following (in thousands):

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

Certain of our debt instruments require that we comply with a number of restrictive financial covenants. As of ~~March 31,~~September 30, 2019, we were within the compliance requirements of these financial covenants.

We capitalized interest costs of ~~$2.0~~$2.9 million in the three months ended ~~March 31,~~September 30, 2019, ~~and~~ $1.4 million in the three months ended ~~March 31,~~September 30, 2018, $7.3 million in the nine months ended September 30, 2019 and $4.2 million in the nine months ended September 30, 2018.

Interest rate derivatives $ (8,845 ) $ 4,676
$ 570
$ (245 )

Over the next 12 months, we estimate that approximately ~~$817,000 of gains~~$612,000 in losses will be reclassified from accumulated other comprehensive loss (“AOCL”) as ~~a decrease~~an increase to interest expense.

We have agreements with each of our interest rate derivative counterparties that contain provisions under which, if we default or are capable of being declared in default on defined levels of our indebtedness, we could also be declared in default on our derivative obligations. Failure to comply with the loan covenant provisions could result in our being declared in default on any derivative instrument obligations covered by the agreements. As of ~~March 31,~~September 30, 2019, we are not in default with any of

these provisions. As of ~~March 31,~~September 30, 2019, the fair value of interest rate derivatives in a liability position related to these agreements was ~~$12.0~~$34.9 million, excluding the effects of accrued interest and credit valuation adjustments. As of ~~March 31,~~September 30, 2019, we had

not posted any collateral related to these agreements. If we breach any of these provisions, we could be required to settle our obligations under the agreements at their termination value, which was ~~$12.0~~$34.9 million as of ~~March 31,~~September 30, 2019.

11. Redeemable Noncontrolling Interests

Our partners in ~~two~~2 real estate joint ventures, LW Redstone Company, LLC and Stevens Investors, LLC (discussed further in Note 6), have the right to require us to acquire their respective interests at fair value; accordingly, we classify the fair value of our partners’ interests as redeemable noncontrolling interests in the mezzanine section of our consolidated balance sheets. The table below sets forth the activity for these redeemable noncontrolling interests (in thousands):



	For the Nine Months Ended September 30,
	2019			2018
Beginning balance	$	26,260		$	23,125
Contributions from noncontrolling interests	—			186
Distributions to noncontrolling interests	(1,656		)	(1,114		)
Net income attributable to noncontrolling interests	2,729			1,903
Adjustment to arrive at fair value of interests	1,344			1,331
Ending balance	$	28,677		$	25,431

For the Three Months Ended March 31,
2019 2018
Beginning balance $ 26,260
$ 23,125
Distributions to noncontrolling interests (349 ) (452 )
Net income attributable to noncontrolling interests 675
638
Adjustment to arrive at fair value of interests 799
537
Ending balance $ 27,385
$ 23,848

We determine the fair value of the interests based on unobservable inputs after considering the assumptions that market participants would make in pricing the interest. We apply a discount rate to the estimated future cash flows allocable to our partners from the properties underlying the respective joint ventures. Estimated cash flows used in such analyses are based on our plans for the properties and our views of market and economic conditions, and consider items such as current and future rental rates, occupancy projections and estimated operating and development expenditures.

12. Equity

~~During the three months ended March~~COPLP Limited Partner Preferred Units

COPLP has 352,000 Series I Preferred Units outstanding to an unrelated party with an aggregate liquidation preference of $8.8 million ($25.00 per unit), plus any accrued and unpaid distributions of return thereon. On July 31, 2019, we amended the terms of these units to:

reduce the priority annual cumulative return from 7.5% of the units’ liquidation preference to 3.5% effective September 23, 2019, and eliminate provisions for future increases previously in place;

extend the earliest date that COPLP may redeem the units. As amended, the units may be redeemed for cash by COPLP at COPLP’s option on or after January 1, 2020, provided that COPLP provides notice to the unit holder six months prior to the effective date of the redemption; and

establish that COPLP provide notice to the unit holder for defined periods of time in advance of the sale of certain property or repayment or refinancing of certain debt, after which, in certain instances, the unit holder would have the ability to require COPLP to redeem the units at their liquidation preference.

Common Shares/Units

COPT issued 1.6 million common shares under its forward equity sale agreements for net proceeds of $46.5 ~~million.~~million on March 27, 2019, after which it had no remaining capacity under the agreements. COPT contributed the net proceeds from ~~these issuances~~this issuance to COPLP in exchange for an equal number of units in COPLP. ~~COPT has no remaining capacity under the forward equity sale agreements as of March 31, 2019.~~

As of ~~March 31,~~September 30, 2019, COPT had remaining capacity under its at-the-market stock offering program equal to an aggregate gross sales price of $300 million in common share sales.

During the ~~three~~nine months ended ~~March 31,~~September 30, 2019, certain COPLP limited partners converted ~~5,500~~103,039 common units in COPLP for an equal number of common shares in COPT.

We declared dividends per COPT common share and distributions per COPLP common unit of $0.275 in the three months ended ~~March 31,~~September 30, 2019 and 2018 and $0.825 in the nine months ended September 30, 2019 and 2018.

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

13. Information by Business Segment

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

We measure the performance of our segments through the measure we define as net operating income from real estate operations (“NOI from real estate operations”), which includes: real estate revenues and property operating expenses; and the net of revenues and property operating expenses of real estate operations owned through unconsolidated real estate joint ventures (“UJVs”) that is allocable to COPT’s ownership interest (“UJV NOI allocable to COPT”). Amounts reported for segment assets represent long-lived assets associated with consolidated operating properties (including the carrying value of properties, right-of-use assets, net of related lease liabilities, intangible assets, deferred leasing costs, deferred rents receivable and lease incentives) and the carrying value of investments in UJVs owning operating properties. Amounts reported as additions to long-lived assets represent additions to existing consolidated operating properties, excluding transfers from non-operating properties, which we report separately.

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

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

The change in the contract liabilities balance reported above for the ~~three~~nine months ended ~~March 31,~~September 30, 2018 was due primarily to our satisfaction of performance obligations during the period on a contract on which we previously received advance payments from a customer.

Revenue allocated to the remaining performance obligations under existing contracts as of ~~March 31,~~September 30, 2019 that will be recognized as revenue in future periods was ~~$51.6~~$27.5 million, approximately ~~$45~~$23 million of which we expect to recognize during the remainder of 2019.

We have no deferred incremental costs incurred to obtain or fulfill our construction contracts or other service revenues and had no impairment losses on construction contracts receivable or unbilled construction revenue ~~for~~in the three or nine months ended ~~March 31,~~September 30, 2019 and 2018.

15. Share-Based Compensation

Restricted Shares

During the ~~three~~nine months ended ~~March 31,~~ September 30, 2019, certain employees and non-employee members of our Board of Trustees (“Trustees”) were granted a total of ~~135,396~~185,095 restricted common shares with an aggregate grant date fair value of ~~$3.5~~$4.9 million ~~($25.81~~(weighted average of $26.41 per share). Restricted shares granted to employees vest

based on increments and over periods of time set forth under the terms of the respective awards provided that the employee remains employed by us. Restricted shares granted to non-employee Trustees vest on the first anniversary of the grant date, provided that the Trustee remains in his or her position. During the ~~three~~nine months ended ~~March 31,~~ September 30, 2019, forfeiture restrictions lapsed on ~~151,252~~175,973 previously issued common shares; these shares had a weighted average grant date fair value of ~~$27.94~~$28.05 per share, and the aggregate intrinsic value of the shares on the vesting dates was ~~$3.9~~$4.6 million.

Deferred Share Awards

During the nine months ended September 30, 2019, certain non-employee Trustees were granted a total of 3,432 deferred share awards with an aggregate grant date fair value of $95,000 ($27.60 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). During the nine months ended September 30, 2019, we issued 3,097 common shares in settlement of deferred share awards; these shares had a grant date fair value of $26.77 per share, and the aggregate intrinsic value of the shares on the settlement date was $86,000.

Performance Share Awards (“PSUs”)

We issued 44,757 common shares on January 18, 2019 to executives in settlement of PSUs granted in 2016, representing 157% of the target award for those PSUs.

PIUs

Commencing in 2019, we offered our executives and Trustees the opportunity to select PIUs as a form of long-term compensation in lieu of, or in combination with, other forms of share-based compensation awards (restricted shares, deferred share awards and PSUs). PIUs are a special class of common unit structured to qualify as “profit interests” for tax purposes. Our executives and certain of our Trustees selected PIUs as their form of share-based compensation for their 2019 grants. We granted ~~the executives two~~2 forms of PIUs: time-based PIUs (“TB-PIUs”); and performance-based PIUs (“PB-PIUs”). TB-PIUs are subject to forfeiture restrictions until the end of the requisite service period, at which time the TB-PIUs automatically convert into vested PIUs. PB-PIUs are subject to a market condition in that the number of earned awards are determined at the end of the performance period (as described further below) and then settled in vested PIUs. Vested PIUs carry substantially the same rights to redemption and distributions as non-PIU common units.

TB-PIUs

During the ~~three~~nine months ended ~~March 31,~~ September 30, 2019, our executives and certain non-employee Trustees were granted a total of ~~54,956~~61,820 TB-PIUs with an aggregate grant date fair value of ~~$1.4~~$1.6 million ~~($25.81~~(weighted average of $26.01 per TB-PIU). TB-PIUs granted to executives vest in equal one-third increments over a three-year period beginning on the first anniversary of the date of grant. TB-PIUs granted to non-employee Trustees vest on the first anniversary of the grant date, provided that the Trustee remains in his or her position. Prior to vesting, TB-PIUs carry substantially the same rights to distributions as non-PIU common units but carry no redemption rights.

PB-PIUs

On January 1, 2019, we granted our executives 193,682 PB-PIUs with a three-year performance period concluding on the earlier of December 31, 2021 or the date of: (1) termination by us without cause, death or disability of the executive or constructive discharge of the executive (collectively, “qualified termination”); or (2) a sale event. The number of earned awards at the end of the performance period will be determined based on the percentile rank of COPT’s total shareholder return relative to a peer group of companies, as set forth in the following schedule:



Percentile Rank		Earned Awards 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~~2 of the percentile ranks set forth in the table above, then the percentage of the earned awards will be interpolated between the ranges set forth in the table above to reflect any performance between the listed percentiles. During the performance period, PB-PIUs carry rights to distributions equal to 10% of the distribution rights of non-PIU common units but carry no redemption rights.

At the end of the performance period, we will settle the award by issuing vested PIUs equal to the number of earned awards in settlement of the award plan and paying cash equal to the excess, if any, of: the aggregate distributions that would have been paid with respect to vested PIUs issued in settlement of the earned awards through the date of settlement had such vested PIUs been issued on the grant date; over the aggregate distributions made on the PB-PIUs during the performance period. If a performance period ends due to a sale event or qualified termination, the number of earned awards is prorated based on the portion of the three-year performance period that has elapsed. If employment is terminated by the employee or by us for cause, all PB-PIUs are forfeited.

These PB-PIUs had an aggregate grant date fair value of $2.4 million ($12.47 per PB-PIU) which is being recognized over the performance period. The grant date fair value was computed using a Monte Carlo model that included the following

assumptions: baseline common share value of $21.03; expected volatility for common shares of 21.0%; and a risk-free interest rate of 2.51%.

We present both basic and diluted EPS. We compute basic EPS by dividing net income available to common shareholders allocable to unrestricted common shares under the two-class method by the weighted average number of unrestricted common shares outstanding during the period. Our computation of diluted EPS is similar except that:

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

COPLP and Subsidiaries EPU

We present both basic and diluted EPU. We compute basic EPU by dividing net income available to common unitholders allocable to unrestricted common units under the two-class method by the weighted average number of unrestricted common units outstanding during the period. Our computation of diluted EPU is similar except that:

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. Management believes that it is reasonably possible that we could incur losses pursuant to such claims but do not believe such losses would materially affect our financial position, liquidity or results of operations. Our assessment of the potential outcomes of these matters involves significant judgment and is subject to change based on future developments.

Environmental

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

In connection with a lease and subsequent sale in 2008 and 2010 of ~~three~~3 properties in Dayton, New Jersey, we agreed to provide certain environmental indemnifications limited to $19 million in the aggregate. We have insurance coverage in place to mitigate much of any potential future losses that may result from these indemnification agreements.

Tax Incremental Financing Obligation

~~In August 2010,~~ Anne Arundel County, Maryland issued~~$30 million~~ in tax incremental financing bonds to third-party investors in order to finance public improvements needed in connection with our project known as the National Business ~~Park North.~~Park. These bonds had a remaining principal balance of approximately $34 million as of September 30, 2019. The real estate taxes on increases in assessed ~~value~~values post-bond issuance of aproperties in development ~~district~~districts encompassing the National Business Park ~~North~~ are ~~to be~~ transferred to a special fund pledged to the repayment of the bonds. While we are obligated to fund, through a special tax, any future shortfalls between debt service of the bonds and real estate taxes available to repay the bonds, as of ~~March 31,~~September 30, 2019, we do not expect any such future fundings will be required.

Contractual Obligations

We had amounts remaining to be incurred under various contractual obligations as of ~~March 31,~~September 30, 2019 that included the following (excluding amounts incurred and therefore reflected as liabilities reported on our consolidated balance sheets):

development and redevelopment obligations of ~~$184.3~~$217.1 million;

tenant and other capital improvements of ~~$45.3~~$60.8 million;

third party construction obligations of ~~$32.6~~$13.5 million; and

other obligations of ~~$1.7~~$1.6 million.

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

Overview

During the ~~three~~nine months ended~~March 31,~~September 30, 2019:

we finished the period with our office and data center shell portfolio ~~92.6%~~92.7% occupied;

we placed into service ~~181,000~~804,000 square feet in ~~three~~seven newly-constructed properties and one redeveloped property that were 100.0% leased as of ~~March 31,~~September 30, 2019;

we sold a 90% interest in seven data center shell properties based on an aggregate property value of $265.0 million and retained a 10% interest in the properties through BREIT-COPT, a newly-formed joint venture. Our partner in the joint venture acquired the 90% interest from us for $238.5 million, most of which was used by us to repay borrowings under our Revolving Credit Facility that funded development costs; and

COPT issued 1.6 million common shares under its forward equity sale agreements for net proceeds of $46.5 million. COPT contributed the net proceeds from these issuances to COPLP in exchange for an equal number of units in COPLP. The proceeds were used primarily to repay borrowings under our Revolving Credit Facility that funded development costs.

With regard to our operating portfolio square footage, occupancy and leasing statistics included below and elsewhere in this Quarterly Report on Form 10-Q, amounts disclosed include information pertaining to ~~six~~ properties owned through an unconsolidated real estate joint ~~venture except for amounts reported for Annualized Rental Revenue, which represent the portion attributable to our ownership interest.~~ventures.

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

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

how we expect to generate cash for short and long-term capital needs; and

our commitments and contingencies.

You should refer to our consolidated financial statements and the notes thereto as you read this section.

This section contains “forward-looking” statements, as defined in the Private Securities Litigation Reform Act of 1995, that are based on our current expectations, estimates and projections about future events and financial trends affecting the financial condition and operations of our business. Forward-looking statements can be identified by the use of words such as “may,” “will,” “should,” “could,” “believe,” “anticipate,” “expect,” “estimate,” “plan” or other comparable terminology. Forward-looking statements are inherently subject to risks and uncertainties, many of which we cannot predict with accuracy and some of which we might not even anticipate. Although we believe that the expectations, estimates and projections reflected in such forward-looking statements are based on reasonable assumptions at the time made, we can give no assurance that these expectations, estimates and projections will be achieved. Future events and actual results may differ materially from those discussed in the forward-looking statements. Important factors that may affect these expectations, estimates and projections include, but are not limited to:

general economic and business conditions, which will, among other things, affect office property and data center demand and rents, tenant creditworthiness, interest rates, financing availability and property values;

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

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

our ability to borrow on favorable terms;

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

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

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

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

possible adverse changes in tax laws;

the dilutive effects of issuing additional common shares;

our ability to achieve projected results;

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

environmental requirements.

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

During the ~~three~~nine months ended ~~March 31,~~ September 30, 2019, we completed ~~956,000~~4.2 million square feet of leasing, including: renewed leases on ~~291,000~~1.5 million square feet, representing ~~71.3%~~75.4% of the square footage of our lease expirations (including the effect of early renewals); ~~539,000~~2.1 million square feet of development and redevelopment space; and ~~126,000~~622,000 square feet of vacant space.

Wholesale Data Center

Our 19.25 megawatt wholesale data center was 82.1% leased as of September 30, 2019 and 87.6% leased as of ~~March~~December 31, 2018. Based on known lease terminations and non-renewals, we expect that the leased percentage of this property will decline to approximately 77% (or 14.8 megawatts) by December 2019 and ~~December 31, 2018.~~70% (or 13.6 megawatts) by July 2020.

We evaluate the operating performance of our properties using NOI from real estate operations, our segment performance measure, which includes: real estate revenues and property operating expenses; and the net of revenues and property operating expenses of real estate operations owned through unconsolidated real estate joint ventures (“UJVs”) that is allocable to COPT’s ownership interest (“UJV NOI allocable to COPT”). We view our NOI from real estate operations as comprising the following primary categories:

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

Since both of the measures discussed above exclude certain items includable in net income, reliance on these measures has limitations; management compensates for these limitations by using the measures simply as supplemental measures that are considered alongside other GAAP and non-GAAP measures. A reconciliation of NOI from real estate operations and NOI from service operations to net income reported on the consolidated statements of operations of COPT and subsidiaries is provided in Note 13 to our consolidated financial statements.

Comparison of Statements of Operations for the Three Months Ended ~~March 31,~~September 30, 2019 and 2018

Our Same Properties pool consisted of ~~156~~150 properties, comprising ~~94.7%~~86.2% of our office and data center shell portfolio’s square footage as of ~~March 31,~~September 30, 2019. This pool of properties changed from the pool used for purposes of comparing 2018 and 2017 in our 2018 Annual Report on Form 10-K due to the addition of nine properties placed in service and 100% operational on or before January 1, ~~2018.~~2018 and the removal of six properties in which we sold a 90% interest in June 2019.

Our NOI from constructed and redeveloped properties placed in service included ~~nine~~12 properties and land under a long-term contract placed in service in 2018 and 2019.

NOI from Service Operations

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

Interest expense decreased due primarily to increased capitalized interest resulting from a higher volume of active construction and development projects.

NOI from Service Operations



	For the Nine Months Ended September 30,
	2019		2018		Variance
	(in thousands)
Construction contract and other service revenues	$	87,946	$	53,202	$	34,744
Construction contract and other service expenses	85,130		51,215		33,915
NOI from service operations	$	2,816	$	1,987	$	829

Construction contract and other service revenue and expenses increased due primarily to a higher volume of construction activity in connection with several of our tenants.

General, administrative and leasing expenses

General, administrative and leasing expenses increased in large part due toto: higher legal and professional expenses and information technology related expenses; and our adoption of lease accounting guidance in the current period under which we no longer defer recognition of non-incremental leasing costs.

Gain on sales of real estate

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

Funds from Operations

Funds from operations (“FFO”) is defined as net income computed using GAAP, excluding gains on sales and impairment losses of real estate (net of associated income tax) and real estate-related depreciation and amortization. FFO also includes adjustments to net income for the effects of the items noted above pertaining to UJVs that were allocable to our ownership interest in the UJVs. We believe that we use the National Association of Real Estate Investment Trusts (“Nareit”) definition of FFO, although others may interpret the definition differently and, accordingly, our presentation of FFO may differ from those of other REITs. We believe that FFO is useful to management and investors as a supplemental measure of operating performance because, by excluding gains on sales and impairment losses of real estate ~~net~~(net of ~~related tax benefit,~~associated income tax), and ~~excluding~~ real estate-related depreciation and amortization, FFO can help one compare our operating performance between periods. In addition, since most equity REITs provide FFO information to the investment community, we believe that FFO is useful to investors as a supplemental measure for comparing our results to those of other equity REITs. We believe that net income is the most directly comparable GAAP measure to FFO.

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

Basic FFO available to common share and common unit holders (“Basic FFO”) is FFO adjusted to subtract (1) preferred share dividends, (2) issuance costs associated with redeemed preferred shares, (3) income attributable to noncontrolling interests through ownership of preferred units in the Operating Partnership or interests in other consolidated entities not owned by us, (4) depreciation and amortization allocable to noncontrolling interests in other consolidated entities and (5) Basic FFO allocable to share-based compensation awards. With these adjustments, Basic FFO represents FFO available to common shareholders and common unitholders. Common units in the Operating Partnership are substantially similar to our common shares and are exchangeable into common shares, subject to certain conditions. We believe that Basic FFO is useful to investors due to the close correlation of common units to common shares. We believe that net income is the most directly comparable GAAP measure to Basic FFO. Basic FFO has essentially the same limitations as FFO; management compensates for these limitations in essentially the same manner as described above for FFO.

Diluted FFO available to common share and common unit holders (“Diluted FFO”) is Basic FFO adjusted to add back any changes in Basic FFO that would result from the assumed conversion of securities that are convertible or exchangeable into common shares. We believe that Diluted FFO is useful to investors because it is the numerator used to compute Diluted FFO per share, discussed below. We believe that net income is the most directly comparable GAAP measure to Diluted FFO. Since

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

Diluted FFO available to common share and common unit holders, as adjusted for comparability is defined as Diluted FFO adjusted to exclude operating property acquisition costs; gain or loss on early extinguishment of debt; FFO associated with properties securing non-recourse debt on which we have defaulted and which we have extinguished, or expect to extinguish, via conveyance of such properties, including property NOI, interest expense and gains on debt extinguishment; loss on interest rate derivatives; demolition costs on redevelopment and nonrecurring improvements; executive transition costs; ~~and~~ issuance costs associated with redeemed preferred ~~shares.~~shares; and certain other expenses that we believe are not closely correlated with our operating performance. This measure also includes adjustments for the effects of the items noted above pertaining to UJVs that were allocable to our ownership interest in the UJVs. We believe this to be a useful supplemental measure alongside Diluted FFO as it excludes gains and losses from certain investing and financing activities and certain other items that we believe are not closely correlated to (or associated with) our operating performance. We believe that net income is the most directly comparable GAAP measure to this non-GAAP measure. This measure has essentially the same limitations as Diluted FFO, as well as the further limitation of not reflecting the effects of the excluded items; we compensate for these limitations in essentially the same manner as described above for Diluted FFO.

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

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

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

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

The table below sets forth the computation of the above stated measures for the three and nine months ended ~~March 31,~~September 30, 2019 and 2018, and provides reconciliations to the GAAP measures of COPT and subsidiaries associated with such measures:

Net cash flow from operating activities increased ~~$28.5~~$35.4 million when comparing the ~~three~~nine months ended ~~March 31,~~September 30, 2019 and 2018 due primarily to our payment in 2018 of construction costs on a contract that the customer pre-funded to us in prior years.

Net cash flow ~~provided by~~used in financing activities in the ~~three~~nine months ended ~~March 31,~~September 30, 2019 was ~~$66.3~~$22.6 million, and included the following:

Net cash flow provided by financing activities in the ~~three~~nine months ended ~~March 31,~~September 30, 2018 was ~~$6.3~~$29.1 million, and included the following:

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

As of ~~March 31,~~September 30, 2019, COPT owned ~~98.6%~~98.7% of the outstanding common units in COPLP; the remaining common units and all of the outstanding preferred units were owned by third parties. As the sole general partner of COPLP, COPT has the full, exclusive and complete responsibility for COPLP’s day-to-day management and control.

The liquidity of COPT is dependent on COPLP’s ability to make sufficient distributions to COPT. The primary cash requirement of COPT is its payment of dividends to its shareholders. COPT also guarantees some of the Operating Partnership’s debt, as discussed further in Note 9 of the notes to consolidated financial statements included herein. If the Operating Partnership fails to fulfill certain of its debt requirements, which trigger COPT’s guarantee obligations, then COPT will be required to fulfill its cash payment commitments under such guarantees. However, COPT’s only significant asset is its investment in COPLP.

As discussed further below, we believe that the Operating Partnership’s sources of working capital, specifically its cash flow from operations, and borrowings available under its Revolving Credit Facility, are adequate for it to make its distribution payments to COPT and, in turn, for COPT to make its dividend payments to its shareholders.

COPT’s short-term liquidity requirements consist primarily of funds to pay for future dividends expected to be paid to its shareholders. COPT periodically accesses the public equity markets to raise capital by issuing common and/or preferred shares.

For COPT to maintain its qualification as a REIT, it must pay dividends to its shareholders aggregating annually to at least 90% of its ordinary taxable income. As a result of this distribution requirement, it cannot rely on retained earnings to fund its ongoing operations to the same extent that some other companies can. COPT may need to continue to raise capital in the equity markets to fund COPLP’s working capital needs, development activities and acquisitions.

COPLP’s primary cash requirements are for operating expenses, debt service, development of new properties, improvements to existing properties and acquisitions, to the extent they are pursued in the future. We expect COPLP to continue to use cash flow provided by operations as the primary source to meet its short-term capital needs, including property operating expenses, general and administrative expenses, interest expense, scheduled principal amortization of debt, distributions to its security holders and improvements to existing properties. As of ~~March 31,~~September 30, 2019, COPLP had ~~$7.8~~$34.0 million in cash and cash equivalents.

COPLP’s senior unsecured debt is currently rated investment grade by the three major rating agencies. We aim to maintain an investment grade rating to enable COPLP to use debt comprised of unsecured, primarily fixed-rate debt (including the effect of interest rate swaps) from public markets and banks. COPLP also uses secured nonrecourse debt from institutional lenders and banks for joint venture financing. In addition, COPLP periodically raises equity from COPT when COPT accesses the public equity markets by issuing common and/or preferred shares.

COPLP uses its Revolving Credit Facility to initially finance much of its investing activities. COPLP subsequently pays down the facility using cash available from operations and proceeds from long-term borrowings, equity issuances and sales of interests in properties. The lenders’ aggregate commitment under the facility is $800.0 million, with the ability for COPLP to increase the lenders’ aggregate commitment to $1.25 billion, provided that there is no default under the facility and subject to the approval of the lenders. The facility matures in March 2023, and may be extended by two six-month periods at COPLP’s option, provided that there is no default under the facility and COPLP pays an extension fee of 0.075% of the total availability under the facility for each extension period. As of ~~March 31,~~September 30, 2019, the maximum borrowing capacity under this facility totaled $800.0 million, of which ~~$538.0~~$580.0 million was available.

COPT has an equity program in place under which it 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, COPT may also, at its discretion, sell common shares under forward equity sales agreements. The use of a forward equity sales agreement would enable us to lock in a price on a sale of common shares when the agreement is executed but defer receiving the proceeds from the sale until a later date.

We believe that COPLP’s liquidity and capital resources are adequate for its near-term and longer-term requirements without necessitating property sales. ~~We do, however, expect~~However, we are under contract to ~~raise at least $200 million from sales of~~sell controlling interests in two data center shell properties ~~during~~in Virginia for $67 million; we expect this sale to occur in the ~~remainder~~fourth quarter of ~~2019 and use the proceeds to repay borrowings and fund construction and development costs.~~2019.

The following table summarizes our contractual obligations as of ~~March 31,~~September 30, 2019 (in thousands):

Represents interest costs for our outstanding debt as of ~~March 31,~~September 30, 2019 for the terms of such debt. For variable rate debt, the amounts reflected above used ~~March 31,~~September 30, 2019 interest rates on variable rate debt in computing interest costs for the terms of such debt. We expect to pay these items using cash flow from operations.

We expect to spend approximately ~~$240~~$80 million on construction and development costs and approximately ~~$55~~$25 million on improvements and leasing costs for operating properties (including the commitments set forth in the table above) during the remainder of 2019. We expect to fund the construction and development costs initially using primarily borrowings under our Revolving Credit Facility. We expect to fund improvements to existing operating properties using cash flow from operating activities. ~~We expect to use proceeds from sales of property interests to repay borrowings under our Revolving Credit Facility.~~

Certain of our debt instruments require that we comply with a number of restrictive financial covenants, including maximum leverage ratio, unencumbered leverage ratio, minimum net worth, minimum fixed charge coverage, minimum unencumbered interest coverage ratio, minimum debt service and maximum secured indebtedness ratio. As of ~~March 31,~~September 30, 2019, we were compliant with these covenants.

Off-Balance Sheet Arrangements

We had no material off-balance sheet arrangements during the ~~three~~nine months ended ~~March 31,~~September 30, 2019.

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

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

Item 3.Quantitative and Qualitative Disclosures about Market Risk

We are exposed to certain market risks, one of the most predominant of which is a change in interest rates. Increases in interest rates can result in increased interest expense under our Revolving Credit Facility and other variable rate debt. Increases in interest rates can also result in increased interest expense when our fixed rate debt matures and needs to be refinanced.

The following table sets forth as of ~~March 31,~~September 30, 2019 our debt obligations and weighted average interest rates on debt maturing each year (dollars in thousands):

The fair value of our debt was ~~$1.9~~$1.9 billion as of ~~March 31, 2019~~.September 30, 2019. If interest rates had been 1% lower, the fair value of our fixed-rate debt would have increased by approximately ~~$53~~$48 million as of ~~March 31,~~September 30, 2019.

See Note 10 to our consolidated financial statements for information pertaining to interest rate swap contracts in place as of ~~March 31,~~September 30, 2019 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 ~~$481,000~~$1.4 million in the ~~three~~nine months ended ~~March 31,~~September 30, 2019 if the applicable LIBOR rate was 1% higher.

Item 4.Controls and Procedures

(a)Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of COPT’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of ~~March 31,~~September 30, 2019. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that COPT’s disclosure controls and procedures as of ~~March 31,~~September 30, 2019 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 its management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
