EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended September 30, 2015 of Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company”) and Corporate Office Properties, L.P. (“COPLP”) and subsidiaries (collectively, the “Operating Partnership”). Unless stated otherwise or the context otherwise requires, “we,” “our,” and “us” refer collectively to COPT, COPLP and their subsidiaries.

COPT is a real estate investment trust, or REIT, and the sole general partner of COPLP. As of September 30, 2015, COPT owned approximately 96.3% of the outstanding common units and approximately 95.5% of the outstanding preferred units in COPLP; the remaining common and preferred units in COPLP were owned by third parties. As the sole general partner of COPLP, COPT controls COPLP and can cause it to enter into major transactions including acquisitions, dispositions and refinancings and cause changes in its line of business, capital structure and distribution policies.

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

Noncontrolling interests and shareholders’ equity and partners’ capital are the main areas of difference between the consolidated financial statements of COPT and those of COPLP. The common limited partnership interests in COPLP not owned by COPT are accounted for as partners’ capital in COPLP’s consolidated financial statements and as noncontrolling interests in COPT’s consolidated financial statements. COPLP’s consolidated financial statements also reflect COPT’s noncontrolling interests in certain real estate partnerships, limited liability companies (“LLCs”), business trusts and corporations; the differences between shareholders’ equity, partners’ capital and noncontrolling interests result from the differences in the equity issued at the COPT and COPLP levels and in COPT’s noncontrolling interests in these real estate partnerships, LLCs, business trusts and corporations. The only other significant differences between the consolidated financial statements of COPT and those of COPLP are assets in connection with a non-qualified elective deferred compensation plan

(comprised primarily of mutual funds and equity securities) and the corresponding liability to the plan’s participants that are held directly by COPT.

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


•	combined reports better reflect how management and the analyst community view the business as a single operating unit;


•	combined reports enhance investors’ understanding of the Company and the Operating Partnership by enabling them to view the business as a whole and in the same manner as management;


•	combined reports are more efficient for the Company and the Operating Partnership and result in savings in time, effort and expense; and


•	combined reports are more efficient for investors by reducing duplicative disclosure and providing a single document for their review.

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


•	consolidated financial statements;


•	the following notes to the consolidated financial statements:


•	Note 3, Fair Value Measurements of COPT and subsidiaries and COPLP and subsidiaries; and


•	Note 16, Earnings per Share of COPT and subsidiaries and Earnings per Unit of COPLP and subsidiaries;


•	“Item 2: Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources of COPT”; and


•	“Item 2: Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources of COPLP.”

This report also includes separate sections under Part 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.

Corporate Office Properties Trust and Subsidiaries and Corporate Office Properties, L.P. and Subsidiaries

Notes to Consolidated Financial Statements

(unaudited)

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 focus primarily on serving the specialized requirements of United States Government agencies and their contractors, most of whom are engaged in national security and information technology related activities. We generally acquire, develop, manage and lease office and data center properties concentrated in large office parks located near knowledge-based government demand drivers and/or in targeted markets or submarkets in the Greater Washington, DC/Baltimore region. As of September 30, 2015, our properties included the following:


•	183 operating office properties totaling 18.8 million square feet;


•	10 office properties under, or contractually committed for, construction or redevelopment that we estimate will total approximately 1.2 million square feet upon completion, including one partially operational property included above;


•	1,450 acres of land we control that we believe are potentially developable into approximately 17.7 million square feet; and


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

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

Equity interests in COPLP are in the form of common and preferred units. As of September 30, 2015, COPT owned 96.3% of the outstanding COPLP common units (“common units”) and 95.5% of the outstanding COPLP preferred units (“preferred units”); the remaining common and preferred units in COPLP were owned by third parties. Common units in COPLP not owned by COPT carry certain redemption rights. The number of common units in COPLP owned by COPT is equivalent to the number of outstanding common shares of beneficial interest (“common shares”) of COPT, and the entitlement of all COPLP common units to quarterly distributions and payments in liquidation is substantially the same as those of COPT common shareholders. Similarly, in the case of each series of preferred units in COPLP held by COPT, there is a series of preferred shares of beneficial interest (“preferred shares”) in COPT that is equivalent in number and carries substantially the same terms as such series of COPLP preferred units. COPT’s common shares are publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “OFC”.

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

2. Summary of Significant Accounting Policies

Basis of Presentation

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

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, 2014 included in our 2014 Annual Report on Form 10-K. The unaudited consolidated financial statements include all adjustments that are necessary, in the opinion of management, to fairly present 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 2014 Annual Report on Form 10-K.

Recent Accounting Pronouncements

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

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

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

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

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

3. Fair Value Measurements

For a description on how we estimate fair value, see Note 3 to the consolidated financial statements in our 2014 Annual Report on Form 10-K.

Recurring Fair Value Measurements

Our partner in a real estate joint venture has the right to require us to acquire its interest at fair value beginning in March 2020; accordingly, we classify the fair value of our partner’s interest as a redeemable noncontrolling interest in the mezzanine section of our consolidated balance sheet. In determining the fair value of our partner’s interest as of September 30, 2015, we used a discount rate of 15.5% which factored in risk appropriate to the level of future property development expected to be undertaken by the joint venture. A significant increase (decrease) in the discount rate used in determining the fair value would result in a significantly (lower) higher fair value. Given our reliance on the unobservable inputs, the valuations are classified in Level 3 of the fair value hierarchy. Please refer to Note 11 for a rollforward of the activity for redeemable noncontrolling interest.

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

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

Nonrecurring Fair Value Measurements

During the nine months ended September 30, 2015, we recognized the following impairment losses resulting from nonrecurring fair value measurements:


•	$1.3 million primarily in the three months ended June 30, 2015 on a property in Northern Virginia that we sold on July 27, 2015 following receipt of an unsolicited offer. This property’s carrying value exceeded its fair value less costs to sell; and


•	$2.3 million in the three months ended September 30, 2015 on three properties in the Greater Baltimore, Maryland (“Greater Baltimore”) region that we concluded no longer met our investment criteria during the period and whose carrying amounts exceeded their estimated fair values less costs to sell. These properties were reclassified as held for sale.

The table below sets forth the fair value hierarchy of the valuation technique we used to determine the fair values of these properties (dollars in thousands):

During the nine months ended September 30, 2014, we recognized impairment losses totaling $1.4 million primarily in connection with certain of our operating properties in the Greater Baltimore region that were disposed of during the period. After shortening our expected holding period for these properties during the period, we determined that the carrying amount of the properties would not likely be recovered from the cash flows from the operations and sales of the properties over the shortened period.

2015 Dispositions

In the nine months ended September 30, 2015, we completed the following dispositions of operating properties:


•	1550 Westbranch Drive, a 160,000 square foot office property in McLean, Virginia (in the Northern Virginia region) for $27.8 million on July 27, 2015; and

•

15000 and 15010 Conference Center Drive, two office properties in Chantilly, Virginia (in the Northern Virginia region) totaling 665,000 square feet. On August 28, 2015, ownership in these properties was transferred to the mortgage lender on a $150.0 million nonrecourse mortgage loan that was secured by the properties and we removed the debt obligation and accrued interest from our balance sheet. The properties had an estimated fair value of $99 million on the transfer date. Upon completion of this transfer, we recognized a gain on early extinguishment of debt of $84.8 million, representing the difference between the mortgage loan and accrued interest payable extinguished over the carrying value of the properties transferred as of the transfer date and related closing costs.

We also sold land during the nine months ended September 30, 2015 for $18.1 million and recognized gains of $4.0 million on the sales.

2015 Construction Activities

During the nine months ended September 30, 2015, we placed into service an aggregate of 897,000 square feet in seven newly constructed office properties located in Northern Virginia, San Antonio, Texas (“San Antonio”), Huntsville, Alabama (“Huntsville”) and the Baltimore/Washington Corridor, and 170,000 square feet in two properties redeveloped in Greater Philadelphia and St. Mary’s County, Maryland. As of September 30, 2015, we had six office properties under construction, or for which we were contractually committed to construct, that we estimate will total 1.0 million square feet upon completion (including one partially operational property), including four in Northern Virginia and two in the Baltimore/Washington Corridor. We also had four office properties under redevelopment that we estimate will total 156,000 square feet upon completion, all of which were located in the Baltimore/Washington Corridor.

In addition to consolidating the terms of these loan facilities, the Consolidated Credit Agreement included the following provisions:

For the Revolving Credit Facility:


•	an extension of the maturity date from July 14, 2017 to May 6, 2019, with the ability for us to further extend such maturity by two six-month periods at our option, provided that there is no default under the facility and we pay an extension fee based on the total availability of the facility for each extension;


•	changes to the interest terms of the facility such that the variable interest rate is based on LIBOR (customarily the 30-day rate) plus 0.875% to 1.600%, as determined by the credit ratings assigned to COPLP by Standard & Poor’s Ratings Services, Moody’s Investors Service, Inc. or Fitch Ratings Ltd. (collectively, the “Ratings Agencies”);


•	changes to the quarterly fee carried by the facility. Such fee is based on the average daily amount of the lenders’ aggregate commitment multiplied by a per annum rate of 0.125% to 0.300%, as determined by the credit ratings assigned to COPLP by the Ratings Agencies; and


•	certain changes to the financial covenants of the facility.

For the term loan facility:


•	an increase in the loan amount from $250.0 million to $300.0 million, with a right for us to borrow up to an additional $200.0 million during the term for an aggregate maximum loan of $500.0 million, subject to certain conditions. We used the proceeds from the $50.0 million increase in the facility to repay a portion of another existing unsecured term loan;


•	an extension of the maturity date of the loan from February 14, 2017 to May 6, 2020;


•	changes to the interest terms of the facility such that the variable interest rate is based on LIBOR (customarily the 30-day rate) plus 0.900% to 1.850%, as determined by the credit ratings assigned to COPLP by the Ratings Agencies; and


•	certain changes to the financial covenants of the facility.

On June 29, 2015, we issued a $300.0 million aggregate principal amount of 5.00% Senior Notes at an initial offering price of 99.510% of their face value. The proceeds from this issuance, after deducting underwriting discounts, but before other offering expenses, were $296.6 million. The notes mature on July 1, 2025. We may redeem the notes, in whole at any time or in part from time to time, at our option, at a redemption price equal to the greater of (1) the aggregate principal amount of the notes being redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the date of redemption) discounted to its present value, on a semi-annual basis at an adjusted treasury rate plus 45 basis points, plus accrued and unpaid interest thereon to the date of redemption. The notes are unconditionally guaranteed by COPT. However, if this redemption occurs on or after three months prior to the maturity date, the redemption price will be equal to 100% of the principal amount of the notes being redeemed, plus accrued and unpaid interest thereon to, but not including, the redemption date. The carrying value of these notes reflects an unamortized discount totaling $3.4 million at September 30, 2015. The effective interest rate under the notes, including amortization of the issuance costs, was 5.15%.

We capitalized interest costs of $1.5 million in the three months ended September 30, 2015, $1.3 million in the three months ended September 30, 2014, $5.6 million in the nine months ended September 30, 2015 and $4.3 million in the nine months ended September 30, 2014.

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



	For the Three Months Ended September 30,					For the Nine Months Ended September 30,
	2015			2014		2015			2014
Amount of (loss) gain recognized in accumulated other comprehensive loss (“AOCL”) (effective portion)	$	(3,638	)	$	1,015	$	(6,720	)	$	(4,738	)
Amount of losses reclassified from AOCL into interest expense (effective portion)	915			756		2,457			2,170

Over the next 12 months, we estimate that approximately $3.5 million of losses will be reclassified from AOCL as 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. These agreements also incorporate the loan covenant provisions of our indebtedness with a lender affiliate of the derivative counterparties. Failure to comply with the loan covenant provisions could result in our being declared in default on any derivative instrument obligations covered by the agreements. As of September 30, 2015, the fair value of interest rate derivatives in a liability position related to these agreements was $5.9 million, excluding the effects of accrued interest and credit valuation adjustments. As of September 30, 2015, we had not posted any collateral related to these agreements. We are not in default with any of these provisions. If we breached any of these provisions, we could be required to settle our obligations under the agreements at their termination value of $6.3 million.

11. Redeemable Noncontrolling Interest

12. Equity

During the nine months ended September 30, 2015, COPT issued 890,241 common shares at a weighted average price of $30.29 per share under its at-the-market (“ATM”) stock offering program established in October 2012. Net proceeds from the shares issued totaled $26.6 million, after payment of $0.4 million in commissions to sales agents. These net proceeds were contributed to COPLP in exchange for 890,241 common units. COPT’s remaining capacity under the ATM Plan is an aggregate gross sales price of $84.0 million in common share sales.

During the nine months ended September 30, 2015, certain COPLP limited partners redeemed 160,160 common units in COPLP for an equal number of common shares in COPT.

See Note 14 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 ten reportable operating office property segments (comprised of: the Baltimore/Washington Corridor; Northern Virginia; San Antonio; Huntsville; Washington, DC — Capitol Riverfront; St. Mary’s and King George Counties; Greater Baltimore; Greater Philadelphia; Colorado Springs; and Other). In our 2015 quarterly reports on Form 10-Q, our Colorado Springs segment is, and will be, included in our Other segment as it is insignificant in the 2014 and 2015 reporting periods. We also have an operating wholesale data center segment. The table below reports segment financial information for our reportable segments (in thousands). We measure the performance of our segments through the measure we define as NOI from real estate operations, which is derived by subtracting property operating expenses from revenues from real estate operations.

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



	For the Three Months Ended September 30,						For the Nine Months Ended September 30,
	2015			2014			2015			2014

Other assets	147,171		198,551
Total COPT consolidated assets	$	3,918,473	$	3,680,188

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

14. Share-Based Compensation

Performance Share Units (“PSUs”)

On March 5, 2015, our Board of Trustees granted 45,656 PSUs with an aggregate grant date fair value of $1.7 million to executives. The PSUs have a performance period beginning on January 1, 2015 and concluding on the earlier of December 31, 2017 or the date of: (1) termination by us without cause, death or disability of the executive or constructive discharge of the executive (collectively, “qualified termination”); or (2) a sale event. The number of PSUs earned (“earned PSUs”) at the end of the performance period will be determined based on the percentile rank of COPT’s total shareholder return relative to a peer group of companies, as set forth in the following schedule:



Percentile Rank		Earned PSUs Payout %
75th or greater		200% of PSUs granted
50th or greater		100% of PSUs granted
25th		50% of PSUs granted
Below 25th		0% of PSUs 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 PSUs will be interpolated between the ranges set forth in the table above to reflect any performance

between the listed percentiles. At the end of the performance period, we, in settlement of the award, will issue a number of fully-vested COPT common shares equal to the sum of:


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


•	the aggregate dividends that would have been paid with respect to the common shares issued in settlement of the earned PSUs through the date of settlement had such shares been issued on the grant date, divided by the share price on such settlement date, as defined under the terms of the agreement.

If a service period ends due to a sale event or qualified termination, the number of earned PSUs is prorated based on the portion of the service period that has elapsed. If employment is terminated by the employee or by us for cause, all PSUs are forfeited. PSUs do not carry voting rights.

We computed a grant date fair value of $36.76 per PSU using a Monte Carlo model, which included assumptions of, among other things, the following: baseline common share value of $29.28; expected volatility for COPT common shares of 19.9%; and a risk-free interest rate of 0.99%. We are recognizing the grant date fair value in connection with these PSU awards over the period commencing on March 6, 2015 and ending on December 31, 2017.

With regard to the PSUs granted to our executives in prior years that were outstanding as of December 31, 2014 as described in our 2014 Annual Report on Form 10-K:


•	the performance period for the PSUs granted to executives on March 1, 2012 ended on December 31, 2014. Based on COPT’s total shareholder return during the performance period relative to its peer group of companies, we issued 40,309 common shares in settlement of the PSUs on March 5, 2015; and


•	we issued 15,289 common shares on March 5, 2015 to Mr. Stephen E. Riffee, our former Chief Financial Officer, upon his departure on February 3, 2015, in settlement of PSUs granted on March 1, 2013 and March 6, 2014.

Restricted Shares

During the nine months ended September 30, 2015, certain employees were granted a total of 193,499 restricted common shares with an aggregate grant date fair value of $5.6 million (weighted average of $28.93 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 employees remain employed by us. During the nine months ended September 30, 2015, forfeiture restrictions lapsed on 163,145 previously issued common shares; these shares had a weighted average grant date fair value of $26.15 per share, and the aggregate intrinsic value of the shares on the vesting dates was $4.6 million.

Deferred Share Awards

During the nine months ended September 30, 2015, nonemployee members of our Board of Trustees were granted a total of 24,056 deferred share awards with an aggregate grant date fair value of $642,000 ($26.70 per share). Deferred share awards vest on the first anniversary of the grant date, provided that the Trustee remains in his or her position. We settle deferred share awards by issuing an equivalent number of common shares upon vesting of the awards or a later date elected by the Trustee (generally upon cessation of being a Trustee). During the nine months ended September 30, 2015, we issued 15,485 common shares in settlement of deferred share awards granted in 2014; these shares had a grant date fair value of $26.77 per share, and the aggregate intrinsic value of the shares on the settlement date was $413,000.

Options

During the nine months ended September 30, 2015, 76,474 options to purchase common shares (“options”) were exercised. The weighted average exercise price of these options was $26.27 per share, and the aggregate intrinsic value of the options exercised was $300,000.

15. Income Taxes

We own a TRS that is subject to Federal and state income taxes. Our TRS’s provision for income taxes consisted of the following (in thousands):



	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2015		2014		2015		2014
Deferred
Federal	$	39	$	83	$	125	$	215
State	9		18		28		42
Total income tax expense	$	48	$	101	$	153	$	257

Items in our TRS contributing to temporary differences that lead to deferred taxes include depreciation and amortization, share-based compensation, certain accrued compensation, compensation paid in the form of contributions to a deferred nonqualified compensation plan and net operating losses that are not deductible until future periods.

Our TRS’s combined Federal and state effective tax rate was 37.7% for the three and nine months ended September 30, 2015 and 2014.

16. Earnings Per Share (“EPS”) and Earnings Per Unit (“EPU”)

COPT and Subsidiaries EPS

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


•	the denominator is increased to include: (1) the weighted average number of potential additional common shares that would have been outstanding if securities that are convertible into COPT common shares were converted; and (2) the effect of dilutive potential common shares outstanding during the period attributable to share-based compensation using the treasury stock or if-converted methods; and


•	the numerator is adjusted to add back any changes in income or loss that would result from the assumed conversion into common shares that we added to the denominator.

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,
	2015	2014	2015	2014
Conversion of common units	3,679	3,876	—	3,915
Conversion of Series I Preferred Units	176	176	176	176
Conversion of Series K Preferred Shares	—	434	434	434

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


•	weighted average restricted shares and deferred share awards for the three months ended September 30, 2015 and 2014 of 411,000 and 401,000, respectively, and for the nine months ended September 30, 2015 and 2014 of 412,000 and 404,000, respectively; and


•	weighted average options for the three months ended September 30, 2015 and 2014 of 440,000 and 490,000, respectively, and for the nine months ended September 30, 2015 and 2014 of 480,000 and 495,000, respectively.

As discussed in Note 9, we had outstanding senior notes, which we redeemed in April 2015, with an exchange settlement feature, but such notes did not affect our diluted EPS reported above since the weighted average closing price of COPT’s common shares during each of the periods was less than the exchange prices per common share applicable for such periods.

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:


•	the denominator is increased to include: (1) the weighted average number of potential additional common units that would have been outstanding if securities that are convertible into our common units were converted; and (2) the effect of dilutive potential common units outstanding during the period attributable to share-based compensation using the treasury stock or if-converted methods; and


•	the numerator is adjusted to add back any changes in income or loss that would result from the assumed conversion into common units that we added to the denominator.

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

As discussed in Note 9, we had outstanding senior notes, which we redeemed in April 2015, with an exchange settlement feature, but such notes did not affect our diluted EPU reported above since the weighted average closing price of COPT’s common shares during each of the periods was less than the exchange prices per common share applicable for such periods.

17. Commitments and Contingencies

Litigation

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

Environmental

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

Tax Incremental Financing Obligation

In August 2010, Anne Arundel County, Maryland issued $30 million in tax incremental financing bonds to third-party investors in order to finance public improvements needed in connection with our project known as National Business Park North. The real estate taxes on increases in assessed value of a development district encompassing National Business Park North are to be transferred to a special fund pledged to the repayment of the bonds. We recognized a $2.2 million liability through September 30, 2015 representing our estimated obligation to fund through a special tax any future shortfalls between debt service on the bonds and real estate taxes available to repay the bonds.

Operating Leases

We are obligated as lessee under operating leases (mostly ground leases) with various expiration dates extending to the year 2100. Future minimum rental payments due under the terms of these operating leases as of September 30, 2015 follow (in thousands):



Year Ending December 31,
2015 (1)	$	289
2016	1,171
2017	1,096
2018	1,052
2019	1,036
Thereafter	86,999
	$	91,643

(1) Represents three months ending December 31, 2015.

Contractual Obligations

We had amounts remaining to be incurred under various contractual obligations as of September 30, 2015 that included the following:


•	new development and redevelopment obligations of $97.9 million (including acquisitions of land);


•	capital expenditures for operating properties of $41.9 million;


•	third party construction and development of $8.1 million; and


•	other purchase obligations of $4.0 million.

Environmental Indemnity Agreement

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


•	to indemnify the tenant against losses covered under the prior owner’s indemnity agreement if the prior owner fails to indemnify the tenant for such losses. This indemnification is capped at $5.0 million in perpetuity after the State of New Jersey declares the remediation to be complete;


•	to indemnify the tenant for consequential damages (e.g., business interruption) at one of the buildings in perpetuity and another of the buildings through 2025. This indemnification is limited to $12.5 million; and


•	to pay 50% of additional costs related to construction and environmental regulatory activities incurred by the tenant as a result of the indemnified environmental condition of the properties. This indemnification is limited to $300,000 annually and $1.5 million in the aggregate.

18. Subsequent Event

On October 27, 2015, we sold 13200 Woodland Park Road, a 397,000 square foot office property in Herndon, Virginia (in the Northern Virginia region) for $84.0 million, resulting in a gain on sale of approximately $42 million.

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

Overview

During the nine months ended September 30, 2015:


•	we finished the period with occupancy of our portfolio of operating office properties at 91.6%;


•	we leased 11.25 megawatts in our wholesale data center. The center became 100% operational during the period and was 92.5% leased as of period end;


•	we acquired:


◦	250 W. Pratt Street, a 367,000 square foot property in Greater Baltimore that was 96.2% leased, for $61.9 million on March 19, 2015 primarily using borrowings from our Revolving Credit Facility;


◦	2600 Park Tower Drive, a 237,000 square foot property in Northern Virginia that was 100% leased, for $80.5 million on April 15, 2015 primarily using borrowings from our Revolving Credit Facility; and


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


•	we placed into service an aggregate of 1.1 million square feet in seven newly constructed properties and two redeveloped properties that were 97.0% leased as of September 30, 2015;


•	we disposed of:


◦	a 160,000 square foot office property in Northern Virginia for $27.8 million on July 27, 2015. The net proceeds from this sale were used primarily to repay borrowings under our Revolving Credit Facility;


◦	two office properties in Northern Virgina totaling 665,000 square feet that secured a $150.0 million nonrecourse mortgage loan on August 28, 2015. Ownership in these properties was transferred to the mortgage lender and we removed the debt obligation and accrued interest from our balance sheet; and


◦	land for $18.1 million, using most of the resulting proceeds for general corporate purposes;

•

we issued a $300.0 million aggregate principal amount of 5.00% Senior Notes on June 29, 2015 at an initial offering price of 99.510% of their face value. The proceeds from the issuance, after deducting underwriting discounts but before other offering expenses, were approximately $296.6 million. The net proceeds from this issuance were used primarily to repay borrowings under our Revolving Credit Facility; and


•	COPT issued 890,241 common shares at a weighted average price of $30.29 per share under its at-the-market stock offering program established in October 2012. Net proceeds from the shares issued totaled $26.6 million. The net proceeds from the shares issued were contributed to COPLP in exchange for 890,241 common units, and used by COPLP for general corporate purposes.

Subsequent to September 30, 2015, we sold 13200 Woodland Park Road, a 397,000 square foot office property in Herndon, Virginia (in the Northern Virginia region) for $84.0 million. The net proceeds from this sale were used primarily to repay borrowings under our Revolving Credit Facility.

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 a curtailment of demand for additional space by our strategic customers;


•	our ability to borrow on favorable terms;


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


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


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


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


•	the dilutive effects of issuing additional common shares;


•	our ability to achieve projected results; and


•	environmental requirements.

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

Occupancy and Leasing

Office Properties

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

During the nine months ended September 30, 2015, we completed 1.8 million square feet of leasing, including 646,000 of construction and redevelopment space, and renewed 63.9% of the square footage of our lease expirations (including the effect of early renewals). Our changes in regional occupancy rates reflected in the table above included the following:


•	increased occupancy in Northern Virginia due primarily to 580,000 newly constructed square feet placed in service that were 100% occupied;


•	increased occupancy in Huntsville due primarily to a previously vacant 62,000 square foot property and a 69,000 square foot newly-constructed property placed in service during the period that were both 100% occupied at period end; and


•	decreased occupancy in St. Mary’s and King George Counties due to our renewal of 55.5% of the square feet of our lease expirations in the region and a 29,000 square foot redeveloped property placed in service that was vacant at period end.

Occupancy of our Same Office Properties decreased from 90.5% as of December 31, 2014 to 90.3% as of September 30, 2015.

Wholesale Data Center Property

In February 2015, we leased 11.25 megawatts in our wholesale data center with occupancy that commenced in stages. The 19.25 megawatts center became 100% operational during the period. As of September 30, 2015, 17.8 of these megawatts were leased to tenants with further expansion rights of up to a combined 18.9 megawatts.

Results of Operations

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


•	office properties owned and 100% operational throughout the current and prior year reporting periods, excluding properties held for future disposition. We define these as changes from “Same Office Properties”;


•	office properties acquired during the current and prior year reporting periods;


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


•	our wholesale data center;


•	properties held for sale as of September 30, 2015; and


•	property dispositions.

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

We believe that operating income, as reported on our consolidated statements of operations, is the most directly comparable generally accepted accounting principles (“GAAP”) measure for both NOI from real estate operations and NOI from service operations. Since both of these measures exclude certain items includable in operating income, reliance on these measures has limitations; management compensates for these limitations by using the measures simply as supplemental measures that are considered alongside other GAAP and non-GAAP measures.

The table below reconciles NOI from real estate operations and NOI from service operations to operating income reported on the consolidated statements of operations of COPT and subsidiaries:

Our Same Office Properties pool consisted of 147 office properties, comprising 77.6% of our total operating office square footage as of September 30, 2015 (83.4% excluding the effect of properties held for sale). This pool of properties changed from the pool used for purposes of comparing 2014 and 2013 in our 2014 Annual Report on Form 10-K due to the addition of eight properties placed in service and 100% operational by January 1, 2014 and the removal of 19 properties reclassified to held for sale in 2015, one property disposed of and one property reclassified as redevelopment in 2015.

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

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

NOI from Service Operations

	2015		2014		Variance
	(in thousands)
Construction contract and other service revenues	$	17,058	$	34,739	$	(17,681	)
Construction contract and other service expenses	16,132		33,593		(17,461		)
NOI from service operations	$	926	$	1,146	$	(220	)

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

Depreciation and Amortization Expense

The increase in depreciation and amortization expense was attributable primarily to additional expense in the current period of $3.7 million from our office property acquisitions and $3.1 million from our revision of the useful lives of properties that were removed from service for redevelopment.

Business Development Expenses and Land Carry Costs

The increase in business development expenses and land carry costs was due primarily to additional expense in the current period of $2.7 million in acquisition costs expensed in connection with operating property acquisitions and $930,000 in demolition costs on a property undergoing redevelopment.

Gain on Early Extinguishment of Debt

We recognized a gain on early extinguishment of $85.7 million in the current period primarily in connection with our transfer of ownership in two properties serving as collateral for a $150.0 million nonrecourse mortgage loan to the mortgage lender and the removal of the debt obligation and accrued interest from our balance sheet.

Gain on Sales of Real Estate

We recognized gain on sales of real estate in the prior period of $5.5 million on a non-operating property and $5.1 million on operating properties in the Greater Baltimore region.

NOI from service operations	$	2,631	$	5,037	$	(2,406	)

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.

Depreciation and Amortization Expense

The change in depreciation and amortization expense included:


•	additional expense in the current period of $6.2 million from our office property acquisitions and $4.4 million from our revision of the useful lives of properties that were removed from service for redevelopment; and


•	additional expense in the prior period of $12.9 million from our revision of the useful life of a property that was removed from service for redevelopment.

Business Development Expenses and Land Carry Costs

The increase in business development expenses and land carry costs was due primarily to additional expense in the current period of $4.1 million in acquisition costs expensed in connection with operating property acquisitions and $1.2 million in demolition costs on properties undergoing redevelopment.

Gain on Early Extinguishment of Debt

We recognized a gain on early extinguishment of $85.7 million in the current period as described above for the three-month period.

Gain on Sales of Real Estate

We recognized gain on sales of real estate in the current period of $4.0 million pertaining to sales of land in the Greater Baltimore region and in the prior period due to the dispositions discussed above for the three-month period.

Funds from Operations

Funds from operations (“FFO”) is defined as net income computed using GAAP, excluding gains on sales of, and impairment losses on, previously depreciated operating properties, plus real estate-related depreciation and amortization. When multiple properties consisting of both operating and non-operating properties exist on a single tax parcel, we classify all of the gains on sales of, and impairment losses on, the tax parcel as all being for previously depreciated operating properties when most of the value of the parcel is associated with operating properties on the parcel. We believe that we use the National Association of Real Estate Investment Trusts (“NAREIT”) definition of FFO, although others may interpret the definition differently and, accordingly, our presentation of FFO may differ from those of other REITs. We believe that FFO is useful to management and investors as a supplemental measure of operating performance because, by excluding gains related to sales of, and impairment losses on, previously depreciated operating properties, net of related tax benefit, and excluding real estate-related depreciation and amortization, FFO can help one compare our operating performance between periods. In addition, since most equity REITs provide FFO information to the investment community, we believe that FFO is useful to investors as a supplemental measure for comparing our results to those of other equity REITs. We believe that net income is the most directly comparable GAAP measure to FFO.

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

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

Diluted FFO available to common share and common unit holders (“Diluted FFO”) is Basic FFO adjusted to add back any changes in Basic FFO that would result from the assumed conversion of securities that are convertible or exchangeable into common shares. We believe that Diluted FFO is useful to investors because it is the numerator used to compute Diluted FFO per share, discussed below. We believe that the numerator for diluted EPS is the most directly comparable GAAP measure to Diluted FFO. Since Diluted FFO excludes certain items includable in the numerator to diluted EPS, reliance on the measure has limitations; management compensates for these limitations by using the measure simply as a supplemental measure that is weighed in the balance with other GAAP and non-GAAP measures. Diluted FFO is not necessarily an indication of our cash flow available to fund cash needs. Additionally, it should not be used as an alternative to net income when evaluating our financial performance or to cash flow from operating, investing and financing activities when evaluating our liquidity or ability to make cash distributions or pay debt service.

Diluted FFO available to common share and common unit holders, as adjusted for comparability is defined as Diluted FFO adjusted to exclude operating property acquisition costs; gains on sales of, and impairment losses on, properties other than previously depreciated operating properties, net of associated income tax; gain or loss on early extinguishment of debt; FFO associated with properties securing non-recourse debt on which we have defaulted and which we have extinguished, or expect to extinguish, via conveyance of such properties, including property NOI and interest expense (discussed further below); loss on interest rate derivatives; demolition costs on redevelopment properties; executive transition costs; and issuance costs associated with redeemed preferred shares. We believe that the excluded items are not reflective of normal operations and, as a result, we believe that a measure that excludes these items is a useful supplemental measure in evaluating our operating performance. The adjustment for FFO associated with properties securing non-recourse debt on which we have defaulted pertains to the periods subsequent to our default on one loan’s payment terms, which was the result of our decision to not support payments on the loan since the estimated fair value of the properties was less than the loan balance. While we continued as the legal owner of the properties during this period up until the transfer of ownership, all cash flows produced by them went directly to the lender and we did not fund any debt service shortfalls, which included incremental additional interest under the default rate of: $1.3 million in the three months ended September 30, 2015; $5.3 million in the nine months ended September 30, 2015; $1.9 million in the three months September 30, 2014; and $3.8 million in the nine months ended September 30, 2014. We believe that the numerator to diluted EPS 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 that diluted EPS is the most directly comparable GAAP measure to this per share measure. This measure has most of the same limitations as Diluted FFO (described above) as well as the further limitation of not reflecting the effects of the excluded items; we compensate for these limitations in essentially the same manner as described above for Diluted FFO.

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

We use measures called payout ratios as supplemental measures of our ability to make distributions to investors based on each of the following: FFO; Diluted FFO; and Diluted FFO, adjusted for comparability. These measures are defined as (1) the sum of (a) dividends on common shares and (b) distributions to holders of interests in COPLP and dividends on convertible preferred shares when such distributions and dividends are included in Diluted FFO divided by either (2) FFO, Diluted FFO or Diluted FFO, adjusted for comparability.

The table appearing on the following page sets forth the computation of the above stated measures for the three and nine months ended September 30, 2015 and 2014, and provides reconciliations to the GAAP measures of COPT and subsidiaries associated with such measures:

Cash Flows

Net cash flow provided by operating activities increased $3.5 million when comparing the nine months ended September 30, 2015 and 2014 due primarily to:


•	a $10.6 million increase in cash flow from real estate operations due primarily to properties acquired and placed in service since the prior period; and

•

an $8.4 million decrease in interest expense paid from the prior to the current period due in large part to: a $3.9 million decrease in interest paid on the $150.0 million nonrecourse loan that was in default (as discussed above) since we did not support payments on the loan in the current period; and a $1.5 million decrease due to a change in the timing of interest payments resulting from new debt requiring interest payments semi-annually rather than monthly; offset in part by


•	a $11.7 million decrease in cash flow from construction contract and other services from the prior to the current period due in large part to the timing of cash payments and collections on third party construction projects.

Net cash flow used in investing activities increased $234.2 million when comparing the nine months ended September 30, 2015 and 2014 due primarily to cash paid for operating property acquisitions in the current period.

Net cash flow provided by financing activities in the nine months ended September 30, 2015 was $221.3 million, and included the following:


•	net proceeds from debt borrowings of $294.9 million; and


•	net proceeds from the issuance of common shares (or units) of $28.6 million; offset in part by


•	dividends and/or distributions to equity holders of $91.9 million.

Net cash flow provided by financing activities in the nine months ended September 30, 2014 was $21.6 million, and included the following:


•	net proceeds from debt borrowings of $120.2 million; offset in part by


•	dividends and/or distributions to equity holders of $89.2 million; and


•	redemptions of preferred shares (or units) of $50.0 million.

Liquidity and Capital Resources of COPT

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

As of September 30, 2015, COPT owned 96.3% of the outstanding common units and 95.5% of the outstanding preferred units in COPLP; the remaining common and preferred units in COPLP were owned by third parties. As the sole general partner of COPLP, COPT has the full, exclusive and complete responsibility for COPLP’s day-to-day management and control.

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 elsewhere herein. If the Operating Partnership fails to fulfill certain of its debt requirements, which trigger COPT’s guarantee obligations, then COPT will be required to fulfill its cash payment commitments under such guarantees. However, COPT’s only significant asset is its investment in COPLP.

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

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

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

Liquidity and Capital Resources of COPLP

Our primary cash requirements are for operating expenses, debt service, development of new properties, improvements to existing properties and acquisitions. We expect to continue to use cash flow provided by operations as the primary source to meet our short-term capital needs, including property operating expenses, general and administrative expenses, interest expense, scheduled principal amortization of debt, distributions to our security holders and improvements to existing properties. As of September 30, 2015, we had $3.8 million in cash and cash equivalents.

Our senior unsecured debt is currently rated investment grade by the three major rating agencies. We aim to maintain an investment grade rating to enable us to use debt comprised of unsecured, primarily fixed-rate debt (including the effect of interest rate swaps) from public markets and banks. We also use secured nonrecourse debt from institutional lenders and banks, when appropriate. In addition, we periodically access the public equity markets to raise capital by issuing common and/or preferred shares.

We use our Revolving Credit Facility to initially finance much of our investing activities. We subsequently pay down the facility using proceeds from long-term borrowings, equity issuances and property sales. The lenders’ aggregate commitment under the facility is $800.0 million, with the ability for us to increase the lenders’ aggregate commitment to $1.3 billion, provided that there is no default under the facility and subject to the approval of the lenders. Amounts available under the facility are computed based on 60% of our unencumbered asset value, as defined in the loan agreement. The Revolving Credit Facility matures in May 2019, and may be extended by two six-month periods at our option, provided that there is no default under the facility and we pay an extension fee of 0.075% of the total availability of the facility. As of September 30, 2015, the maximum borrowing capacity under this facility totaled $800.0 million, of which $698.2 million was available.

We believe that our liquidity and capital resources are adequate for our near-term and longer-term requirements without necessitating property sales. We do, however, expect to sell properties and use the proceeds to repay borrowings and fund development costs.

The following table summarizes our contractual obligations as of September 30, 2015 (in thousands):



	For the Periods Ending December 31,
	2015		2016		2017		2018		2019		Thereafter		Total

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


(2)	Represents scheduled principal amortization payments and maturities only and therefore excludes a net discount of $11.8 million. As of September 30, 2015, maturities include $36.2 million in 2015 that was extended to 2016 in October 2015 and $100.0 million in 2016 that may be extended to 2017 and $87.0 million in 2019 that may be extended to 2020, both subject to certain conditions.


(3)	Represents interest costs for our outstanding debt as of September 30, 2015 for the terms of such debt. For variable rate debt, the amounts reflected above used September 30, 2015 interest rates on variable rate debt in computing interest costs for the terms of such debt.


(4)	Represents contractual obligations pertaining to new development and redevelopment activities, including land acquisitions.


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


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


(7)	Represents contractual obligations pertaining to recurring and nonrecurring capital expenditures for our operating properties. We expect to finance these costs primarily using cash flow from operations.


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

We expect to spend more than $60 million on construction and development costs and approximately $25 million on improvements to operating properties (including the commitments set forth in the table above) during the remainder of 2015. We expect to fund the construction and development costs using cash on hand and borrowings under our Revolving Credit Facility. We expect to use proceeds from the disposition of properties held for sale to repay future borrowings under our Revolving Credit Facility. We expect to fund improvements to existing operating properties using cash flow from operations.

Certain of our debt instruments require that we comply with a number of restrictive financial covenants, including maximum leverage ratio, unencumbered leverage ratio, minimum net worth, minimum fixed charge coverage, minimum unencumbered interest coverage ratio, minimum debt service and maximum secured indebtedness ratio. As of September 30, 2015, we were in compliance with these financial covenants.

Off-Balance Sheet Arrangements

We had no material off-balance sheet arrangements during the nine months ended September 30, 2015.

Inflation

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

Recent Accounting Pronouncements

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

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

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 September 30, 2015 our debt obligations and weighted average interest rates for fixed rate debt by expected maturity date (dollars in thousands):



	For the Periods Ending December 31,
	2015			2016			2017			2018			2019			Thereafter			Total
Debt:
Fixed rate debt (1)	$	1,560		$	171,929		$	7,186		$	3,017		$	3,117		$	1,303,015		$	1,489,824
Weighted average interest rate	6.37		%	7.18		%	5.06		%	4.52		%	4.51		%	4.31		%	4.65		%
Variable rate debt (2)	$	36,249		$	100,000		$	—		$	—		$	207,000		$	300,000		$	643,249
Weighted average interest rate (3)	2.43		%	1.69		%	—		%	—		%	1.95		%	1.59		%	1.77		%


(1)	Represents principal maturities only and therefore excludes net discounts of $11.8 million.


(2)	As of September 30, 2015, maturities include $36.2 million in 2015 that was extended to 2016 in October 2015 and $100.0 million in 2016 that may be extended to 2017 and $87.0 million in 2019 that may be extended to 2020, both subject to certain conditions.


(3)	The amounts reflected above used September 30, 2015 interest rates on variable rate debt.

The fair value of our debt was $2.2 billion as of September 30, 2015. If interest rates had been 1% lower, the fair value of our fixed-rate debt would have increased by approximately $111 million as of September 30, 2015.

The following table sets forth information pertaining to interest rate swap contracts in place as of September 30, 2015 and December 31, 2014 and their respective fair values (dollars in thousands):



							Fair Value at
Notional Amount			Fixed Rate	Floating Rate Index	Effective Date	Expiration Date	September 30, 2015			December 31, 2014
$	36,249	(1)	3.8300%	One-Month LIBOR + 2.25%	11/2/2010	11/2/2015	$	(44	)	$	(400	)
100,000			0.8055%	One-Month LIBOR	9/2/2014	9/1/2016	(396		)	(317		)
100,000			0.8100%	One-Month LIBOR	9/2/2014	9/1/2016	(401		)	(324		)
100,000			1.6730%	One-Month LIBOR	9/1/2015	8/1/2019	(2,386		)	239
100,000			1.7300%	One-Month LIBOR	9/1/2015	8/1/2019	(2,617		)	35
100,000			0.8320%	One-Month LIBOR	1/3/2012	9/1/2015	—			(407		)
100,000			0.8320%	One-Month LIBOR	1/3/2012	9/1/2015	—			(407		)
							$	(5,844	)	$	(1,581	)


(1)	The notional amount of this instrument is scheduled to amortize to $36.2 million.

Based on our variable-rate debt balances, including the effect of interest rate swap contracts, our interest expense would have increased by $2.0 million in the nine months ended September 30, 2015 if the one-month LIBOR rate was 1% higher.
