Columbia Property Trust intends for all such forward-looking statements presented in this quarterly report on Form 10-Q ("Form 10-Q"), or that management may make orally or in writing from time to time, to be covered by the applicable safe harbor provisions for forward-looking statements contained in those acts.
Such statements in this current Form 10-Q include, among other things, information about possible or assumed future results of the business and our financial condition, liquidity, results of operations, plans, strategies, prospects, and objectives.

risks associated with our ability to continue to qualify as a real estate investment trust ("REIT");
risks associated with possible cybersecurity attacks against us or any of our tenants;
potential liability for uninsured losses and environmental contamination;
potential adverse impact of market interest rates on the market price for our securities; and

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2020
(unaudited)

1.Organization
Columbia Property Trust, Inc. ("Columbia Property Trust") (NYSE: CXP) is a Maryland corporation that operates as a real estate investment trust ("REIT") for federal income tax purposes, and owns and operates commercial real estate properties. Columbia Property Trust conducts business primarily through Columbia Property Trust Operating Partnership, L.P. ("Columbia OP"), a Delaware limited partnership in which Columbia Property Trust is the general partner and majority owner (97.2%). Columbia Property Trust acquires, develops, redevelops, owns, leases, and operates real properties directly, through wholly owned subsidiaries, or through joint ventures. Unless otherwise noted herein, references to Columbia Property Trust, the "Company," "we," "us," or "our" herein shall include Columbia Property Trust and all subsidiaries of Columbia Property Trust, direct and indirect.
As of September 30, 2020, Columbia Property Trust owned 15 operating properties and four properties under development or redevelopment, of which 11 were wholly owned and eight were owned through joint ventures, located in New York, San Francisco, Washington, D.C., and Boston. As of September 30, 2020, these operating properties contained 6.2 million rentable square feet and were approximately 96.3% leased. Columbia Property Trust also provides asset and property management services for 8.0 million square feet of office space located primarily in New York, Washington, D.C., and Boston.

2.    Summary of Significant Accounting Policies
Basis of Presentation
The consolidated financial statements of Columbia Property Trust have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"), including the instructions to Form 10-Q and Article 10 of Regulation S-X, and do not include all of the information and footnotes required by U.S. generally accepted accounting principles ("GAAP") for complete financial statements. In the opinion of management, the statements for the unaudited interim periods presented include all adjustments, which are of a normal and recurring nature, necessary for a fair and consistent presentation of the results for such periods. Results for these interim periods are not necessarily indicative of a full year's results. For additional information on Columbia Property Trust's unconsolidated joint ventures, which are accounted for using the equity method of accounting, see Note 4, Unconsolidated Joint Ventures. Columbia Property Trust's consolidated financial statements include the accounts of Columbia Property Trust, Columbia OP, and any variable-interest entity in which Columbia Property Trust or Columbia OP is deemed the primary beneficiary. With respect to entities that are not variable interest entities, Columbia Property Trust's consolidated financial statements also include the accounts of any entity in which Columbia Property Trust, Columbia OP, or their subsidiaries own a controlling financial interest and any limited partnership in which Columbia Property Trust, Columbia OP, or their subsidiaries own a controlling general partnership interest. All intercompany balances and transactions have been eliminated in consolidation. For further information, refer to the financial statements and footnotes included in Columbia Property Trust's Annual Report on Form 10-K for the year ended December 31, 2019 (the "2019 Form 10-K").
Fair Value Measurements
Columbia Property Trust estimates the fair value of its assets and liabilities (where currently required under GAAP) consistent with the provisions of Accounting Standard Codification 820, Fair Value Measurements ("ASC 820"). Under this standard, fair value is defined as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date, under current market conditions. While various techniques and assumptions can be used to estimate fair value depending on the nature of the asset or liability, the accounting standard for fair value measurements and disclosures provides the following fair value technique parameters and hierarchy, depending upon availability:
Level 1 – Assets or liabilities for which the identical term is traded on an active exchange, such as publicly traded instruments or futures contracts.
Level 2 – Assets or liabilities valued based on observable market data for similar instruments.
11

Table of Contents
Level 3 – Assets or liabilities for which significant valuation assumptions are not readily observable in the market. Such assets or liabilities are valued based on the best available data, some of which may be internally developed. Significant assumptions may include risk premiums that a market participant would consider.
Real Estate Assets
Columbia Property Trust is required to make subjective assessments as to the useful lives of its depreciable assets. To determine the appropriate useful life of an asset, Columbia Property Trust considers the period of future benefit of the asset. These assessments have a direct impact on net income. The estimated useful lives of its assets by class are as follows:
Buildings  40 years
Building and site improvements  
5-25 years
Tenant improvements  Shorter of economic life or lease term
Intangible lease assets  Lease term
As further described in Note 5, Line of Credit and Notes Payable, Columbia Property Trust capitalizes interest incurred on outstanding debt balances as well as joint venture investments, as appropriate, during development or redevelopment of real estate held directly or in unconsolidated joint ventures. During the three months ended September 30, 2020 and 2019, $2.3 million and $0.9 million, respectively, of interest was capitalized to construction in progress; and during the three months ended September 30, 2020 and 2019, $0.5 million and $0.3 million, respectively, of interest was capitalized to investments in unconsolidated joint ventures. During the nine months ended September 30, 2020 and 2019, $7.3 million and $2.9 million, respectively, was capitalized to construction in progress; and during the nine months ended September 30, 2020 and 2019, $1.3 million and $0.9 million, respectively, was capitalized to investments in unconsolidated joint ventures.
Tenant Receivables
Tenant receivables consist of rental and reimbursement billings due from tenants. Tenant receivables are recorded at the original amount earned, which approximates fair value. Management assesses the realizability of tenant receivables on an ongoing basis. When the collectability of tenant receivables is not considered probable, the receivable is written-down against lease revenues. In the third-quarter of 2020, $0.4 million of tenant receivables were written-down against lease revenues.

Straight-Line Rent Receivable

Straight-line rent receivable reflects the amount of cumulative adjustments necessary to present rental income on a straight-line basis. Columbia Property Trust recognizes rental revenues on a straight-line basis, ratably over the term of each lease; however, leases often provide for payment terms that differ from the revenue recognized. When the amount of cash billed is less than the amount of revenue recognized, typically early in the lease, straight-line rent receivable is recorded for the difference. The receivable is depleted during periods later in the lease when the amount of cash paid by the tenant is greater than the amount of revenue recognized. When the collection of rental billings is not considered probable, tenants are moved to "cash basis billings," at which point the corresponding straight-line rent receivable is written-down against lease revenues, and future revenues are recognized upon receipt of payment. In the third quarter of 2020, approximately $50,000 of straight-line rent receivables were written-down against lease revenues.
Assets Held for Sale
Columbia Property Trust classifies properties as held for sale according to Accounting Standard Codification 360, Accounting for the Impairment or Disposal of Long-Lived Assets ("ASC 360"). According to ASC 360, properties having separately identifiable operations and cash flows are considered held for sale when all of the following criteria are met:
Management, having the authority to approve the action, commits to a plan to sell the property.
The property is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such property.

Table of Contents
An active program to locate a buyer and other actions required to complete the plan to sell the property have been initiated.
The property is being actively marketed for sale at a price that is reasonable in relation to its current fair value.
Actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.
The sale of the property is probable (i.e., typically subject to a binding sale contract with a non-refundable deposit), and transfer of the property is expected to qualify for recognition as a completed sale within one year.
The following properties met the above-described criteria and were classified as held for sale in the accompanying consolidated balance sheets as of the following dates:

Evaluating the Recoverability of Real Estate Assets
Columbia Property Trust continually monitors events and changes in circumstances that could indicate that the net carrying amounts of its real estate and related intangible assets and liabilities, of both operating properties and properties under development or redevelopment, may not be recoverable. When indicators of potential impairment are present that suggest that the net carrying amounts of real estate assets and related intangible assets and liabilities may not be recoverable, Columbia Property Trust assesses the recoverability of these net assets by determining whether the respective carrying values will be recovered through the estimated undiscounted future cash flows expected from the use of the net assets and their eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying values, Columbia Property Trust adjusts the carrying values of the real estate assets and related intangible assets and liabilities to the estimated fair values, pursuant to the property, plant, and equipment accounting standard for the impairment or disposal of long-lived assets, and recognizes an impairment loss. At such time that a property is required to be classified as held for sale, its net carrying amount is adjusted to the lower of its depreciated book value or its estimated fair value, less costs to sell, and depreciation is no longer recognized.
Estimated fair values are calculated based on the following hierarchy of information: (i) recently quoted market prices, (ii) market prices for comparable properties, or (iii) the present value of future cash flows, including estimated residual value. Projections of expected future operating cash flows require that Columbia Property Trust estimate future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, the number of months it takes to re-lease the property, and the number of years the property is held for investment, among other factors. Due to the inherent subjectivity of the assumptions used to project future cash flows, estimated fair values may differ from the values that would be realized in market transactions. Certain of Columbia Property Trust's assets may be carried at an amount that exceeds that which could be realized in a current disposition transaction. Columbia Property Trust has determined that the carrying values of its real estate assets and related intangible assets are recoverable as of September 30, 2020.
Intangible Assets and Liabilities Arising From In-Place Leases Where Columbia Property Trust Is the Lessor
Upon the acquisition of real properties, Columbia Property Trust allocates the purchase price of the properties to tangible assets, consisting of land, building, site improvements, and identified intangible assets and liabilities, including the value of in-place leases, based in each case on Columbia Property Trust's estimate of their fair values in accordance with ASC 820 (see "Fair Value Measurements" section above for additional detail). As of September 30, 2020 and December 31, 2019, Columbia Property Trust had the following intangible assets and liabilities, arising from in-place leases, excluding amounts held for sale, if applicable (in thousands):

Investments in Unconsolidated Joint Ventures
Columbia Property Trust uses the equity method to account for investments that are not wholly owned and: (i) are considered variable interest entities where the Company is not the primary beneficiary, or (ii) in which the Company, along with its co-owners, possesses substantive participation rights, including management selection and termination, and the approval of significant capital and operating decisions. Under the equity method, investments in unconsolidated joint ventures are recorded at cost and adjusted for cash contributions and distributions, and allocations of income or loss.
Investments in Real Estate Funds
In connection with the Normandy Acquisition described in Note 3, Transactions, Columbia Property Trust acquired general partnership interests and limited partnership interests in three real estate funds: Normandy Real Estate Fund III, LP; Normandy Real Estate Fund IV, LP; and Normandy Opportunity Zone Fund, LP (collectively, the "Real Estate Funds"). The Company owns minimal economic interests in the Real Estate Funds (ranging from 2.0% to 2.5%). Significant decision rights are shared between the general partners and limited partners; and the general partner can be removed with a majority vote from the limited partners. As a result, Columbia Property Trust accounts for its investments in the Real Estate Funds using the equity method. The Real Estate Funds are subject to the rules of the AICPA Investment Company Guide; as a result, GAAP requires the Company to record its investments in the Real Estate Funds at their respective estimated fair market values. The Company determines the Real Estate Funds' estimated net asset values per share using a discounted cash flow model, which is considered a Level 3 valuation technique (see "Fair Value Measurements" section above). As of September 30, 2020, investments in the Real Estate Funds of approximately $4.3

Table of Contents
million are included in prepaid expenses and other assets on the accompanying consolidated balance sheet. From January 24, 2020 (date of acquisition) through September 30, 2020, Columbia Property Trust recognized an unrealized loss on its investments in Real Estate Funds of approximately $0.6 million, which is recorded as other income (loss) in the accompanying consolidated statements of operations.
Columbia Property Trust has entered into agreements to provide acquisition, disposition, investment management, property management, leasing, and other services to the properties in which the Real Estate Funds own interests. See Note 12, Non-Lease Revenues, for more details. From time to time, Columbia Property Trust may be required to make additional capital contributions to the Real Estate Funds. See Note 7, Commitments and Contingencies, for more details.
Goodwill
Goodwill represents purchase price not specifically assigned to assets acquired and liabilities assumed in a business combination. On January 24, 2020, Columbia Property Trust recorded goodwill of $63.8 million in connection with the Normandy Acquisition (see Note 3, Transactions for details). Columbia Property Trust assesses the recoverability of goodwill on an annual basis, and on an interim basis if an event occurs or circumstances change that would indicate that the carrying value of goodwill may be impaired. When indicators of potential impairment exist, Columbia evaluates whether the carrying value of the reporting unit to which the goodwill relates exceeds the reporting unit's estimated fair value. If the reporting unit's carrying value exceeds its estimated fair value, then goodwill would be reduced, and an impairment loss would be recognized, for the amount of this excess (not to exceed total goodwill). Columbia Property Trust has determined that the carrying value of goodwill is recoverable as of September 30, 2020.

Interest Rate Swap Agreements
Columbia Property Trust enters into interest rate swap contracts to mitigate its interest rate risk on the related financial instruments. Columbia Property Trust does not enter into derivative or interest rate swap transactions for speculative purposes and currently does not have any derivatives that are not designated as hedges; however, certain of its derivatives may, at times, not qualify for hedge accounting treatment. Columbia Property Trust records the fair value of its interest rate swaps on its consolidated balance sheet either as prepaid expenses and other assets or as accounts payable, accrued expenses, and accrued capital expenditures. Changes in the fair value of interest rate swaps that are designated as cash flow hedges are recorded as other comprehensive income (loss). Changes in the fair value of interest rate swaps that do not qualify for hedge accounting treatment are recorded as gain or loss on interest rate swaps. Amounts received or paid under interest rate swap agreements are recorded as interest expense for contracts that qualify for hedge accounting treatment and as gain or loss on interest rate swaps for contracts that do not qualify for hedge accounting treatment. As of September 30, 2020, Columbia Property Trust has two interest rate swaps with an aggregate notional value of $450.0 million. The following tables provide additional information related to Columbia Property Trust's interest rate swaps (in thousands):

Columbia Property Trust applied the provisions of ASC 820 in recording its interest rate swaps at fair value. The fair values of the interest rate swaps, classified under Level 2, were determined using a third-party proprietary model that is based on prevailing market data for contracts with matching durations, current and anticipated London Interbank Offered Rate ("LIBOR") information, and reasonable estimates about relevant future market conditions. Columbia Property Trust has determined that the fair value, as determined by the third party, is reasonable.

During the periods presented, no hedge ineffectiveness was required to be recognized into earnings on the interest rate swaps that qualified for hedge accounting treatment.
Noncontrolling Interests
Noncontrolling interests represent the portion of equity in consolidated entities that is owned by third parties. Noncontrolling interests are adjusted for cash contributions and distributions, and for earnings. Such earnings are allocated between the Company and noncontrolling interests using the hypothetical liquidation at book value method pursuant to the terms of the respective ownership agreements, and are reflected as net income (loss) attributable to noncontrolling interests in the accompanying consolidated statements of operations.
Income Taxes
Columbia Property Trust has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the "Code") and has operated as such beginning with its taxable year ended December 31, 2003. To qualify as a REIT, the Company must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of its REIT taxable income, as defined by the Code, to its stockholders. To the extent that Columbia Property Trust satisfies the distribution requirement but distributes less than 100% of its REIT taxable income, the Company would be subject to federal and state corporate income tax on the undistributed income. Generally, the Company does not incur federal income taxes, other than as described in the following paragraph, because its stockholder distributions typically exceed its taxable income due to noncash expenses such as depreciation. Columbia Property Trust is, however, subject to certain state and local taxes related to the operations of properties in certain locations, which have been provided for in the accompanying consolidated financial statements.
Columbia Property Trust TRS, LLC; Columbia KCP TRS, LLC; Columbia Development TRS 13, LLC; and Columbia Development TRS 87, LLC (collectively, the "TRS Entities") are subsidiaries of the Company and are organized as Delaware limited liability companies. The TRS Entities, among other things, provide services related to asset and property management, construction and development, and other tenant services that Columbia Property Trust, as a REIT, cannot otherwise provide. The Company has elected to treat the TRS Entities as taxable REIT subsidiaries. Columbia Property Trust may perform certain additional, noncustomary services for tenants of its buildings through the TRS Entities; however, earnings of a TRS entity are subject to federal and state income taxes. In addition, for the Company to continue to qualify as a REIT, Columbia Property Trust must limit its investments in taxable REIT subsidiaries to 20% of the value of the total assets. The TRS Entities' deferred tax assets and liabilities represent temporary differences between the financial reporting basis and the tax basis of assets and liabilities based on the enacted rates expected to be in effect when the temporary differences reverse. If applicable, the Company records interest and penalties related to uncertain tax positions as general and administrative expense in the accompanying consolidated statements of operations.
Reclassification
Certain prior-period amounts on the consolidated statement of operations have been reclassified to conform with the current-period's presentation: property operating costs include amounts previously reported as asset and property management fees; and management fee expense includes amounts previously reported as general and administrative – joint venture.
Recent Accounting Pronouncements
In April 2020, the Financial Accounting Standards Board issued guidance on accounting for lease amendments resulting from the economic effects of the COVID-19 pandemic, Topic 842 and Topic 840: Accounting for Lease Concessions Related to the Effects of the COVID-19 Pandemic. The guidance provides a policy election that allows issuers to account
17

Table of Contents
for rent concessions as a continuation of the existing lease, instead of as a lease modification (the "COVID-19 Concession Option") as required under existing GAAP. To be eligible for the COVID-19 Concession Option, aggregate future rent payments cannot be materially more under the amended lease terms than under the original lease terms. Issuers must apply the accounting method selected consistently to leases with similar characteristics and circumstances.
Rent abatements: Under the COVID-19 Concession Option, revenues are reduced for rent abatements (past and future) in the period of execution, and future straight-line rental income is unchanged. Conversely, without adopting the COVID-19 Concession Option, revenues are reduced for past rents forgiven by writing down the related receivables in the period of execution, and future straight-line income is reduced for future rent reductions. Columbia Property Trust has elected to account for rent abatements under existing GAAP. Through September 30, 2020, Columbia Property Trust has abated $0.5 million in rental billings, including the Company's proportionate share of rents earned through unconsolidated joint ventures.
Rent deferrals: Under the COVID-19 Concession Option, rent deferrals may be accounted for as either (a) payment plans, where rents are billed and revenues are recorded on the same schedule; or as (b) variable lease payments, where revenues are not recognized until the amounts become payable in the future based on the amended terms. Conversely, without adopting the COVID-19 Concession option, revenues are recorded on the same schedule, however, deferred rents are recharacterized as straight-line rent receivables until payable. Columbia Property Trust has elected to account for rent deferrals as a lease modification under existing GAAP. Through September 30, 2020, Columbia Property Trust has deferred payments of $2.7 million, including the Company's proportionate share of rents earned through unconsolidated joint ventures.
Accounting Standard Update 2020-04, Reference Rate Reform ("ASC 2020-04"), which was issued on and effective as of March 12, 2020, addresses the accounting and disclosure impacts of reference rate reform and the anticipated discontinuance of LIBOR. ASU 2020-04 provides optional guidance that may be elected over time, and includes practical expedients for activities that impact debt, leases, derivatives, and other contracts. Columbia Property Trust has matched LIBOR-based debt with LIBOR-based interest rate swaps, and has elected to apply the ASU 2020-04's practical expedients related to (i) probability and (ii) the assessment of the effectiveness for future LIBOR-indexed cash flows, which assume that the debt instrument will use the same index rate as its corresponding interest rate swap, once a new reference rate is established to replace LIBOR. Application of these expedients preserves the effectiveness of the Company's interest rate swaps as cash flow hedges in the event that its debt and interest rate swaps are not amended concurrently to reflect a new reference rate. Columbia Property Trust continues to evaluate the impact of the guidance and may apply other elections as additional reference rate changes occur. ASU 2020-04 did not have a material impact on Columbia Property Trust's consolidated financial statements or disclosures.
Accounting Standard Update 2018-13, Fair Value Measurement: Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13"), which became effective for Columbia Property Trust on January 1, 2020, is intended to improve the effectiveness of disclosures required by entities regarding recurring and nonrecurring fair value measurements by removing, modifying, or adding certain disclosures. ASU 2018-13 did not have a material impact on Columbia Property Trust's consolidated financial statements or disclosures.
Recent Disclosure Pronouncement
The SEC's Final Rule Release No. 33-10762, Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates Whose Securities Collateralize a Registrant's Securities (the "SEC Release No. 33-10762") was issued on March 2, 2020 and adopted by Columbia Property Trust in the first quarter of 2020. With respect to the disclosure requirements for subsidiary issuers and guarantors of registered debt securities, SEC Release No. 33-10762 amends SEC Rule 3-10 by, among other things:
Simplifying the criteria that must be met for a parent registrant to qualify for an exemption allowing it to provide summarized financial information in lieu of standalone audited financial statements of the subsidiary issuer, including replacing the requirement that a subsidiary issuer be wholly owned by the parent guarantor with a requirement that the subsidiary issuer be consolidated in the parent guarantor's financial statements.
Upon qualifying for the exemption above, replacing the previous requirement to include condensed consolidating financial information in the registrant's (parent guarantor's) financial statements with a requirement to include certain summarized financial information (Alternative Disclosures) in either the registrant's financial statement footnotes or in its Management’s Discussion and Analysis.

Normandy Acquisition
On January 24, 2020, Columbia Property Trust acquired Normandy Real Estate Management, LLC ("Normandy"), a developer, operator, and investment manager of office and mixed-use assets with a focus on assets in New York, Boston, and Washington, D.C. (the "Normandy Acquisition"). As a result of the Normandy Acquisition, the Company acquired an operating platform, interests in the Real Estate Funds, and contracts to earn fees for providing management services to properties affiliated with the Real Estate Funds (see Note 12, Non-Lease Revenues, for details).
The purchase price, exclusive of adjustments and transaction costs, is comprised of two components: (i) an approximately $14.0 million cash payment, and (ii) the issuance of 3,264,151 Series A Convertible, Perpetual Preferred Units of Columbia OP with a liquidation preference of $26.50 per unit (the "Preferred OP Units"). The Preferred OP Units are convertible for common units of Columbia OP, which are exchangeable into shares of Columbia Property Trust's common stock, subject to certain terms and conditions. As of the closing date of the acquisition, the Preferred OP Units had an estimated fair value of $24.43. The fair value of the Preferred OP Units was determined using a lattice valuation model, utilizing significant unobservable inputs (Level 3 under the fair value hierarchy described in Note 2, Summary of Significant Accounting Policies).

(1)Includes basis differences. There are aggregate net differences between the historical costs recorded at the joint venture level, and Columbia Property Trust's investments in unconsolidated joint ventures of $288.1 million and $279.2 million as of September 30, 2020 and December 31, 2019, respectively. Such basis differences result from the timing of each partner's joint venture interest acquisition; and formation costs incurred by Columbia Property Trust. Basis differences are amortized to income (loss) from unconsolidated joint ventures over the lives of the underlying assets or liabilities.
(2)Columbia Property Trust capitalized interest on its investment in the 799 Broadway Joint Venture and the Terminal Warehouse Joint Venture: $0.5 million and $0.3 million during the three months ended September 30, 2020 and 2019, respectively; and $1.3 million and $0.9 million during the nine months ended September 30, 2020 and 2019, respectively.
(3)Columbia Property Trust owns the following interests in five unconsolidated joint ventures that earn fees for providing management services to properties affiliated with the Real Estate Funds (the "Real Estate Services Joint Ventures"): L&L Normandy Terminal Asset Manager, LLC (67%); L&L Normandy Terminal Development Manager, LLC (50%); L&L Normandy Terminal Property Manager (50%) (collectively, the "Terminal Services Joint Ventures"); WNK Maiden Management (50%); and Maple AB Services, LLC (55%). The Terminal Services Joint Ventures earn fees from providing services to the Terminal Warehouse Joint Venture.
Columbia Property Trust has determined that two of its unconsolidated joint ventures are variable interest entities and the Company is not the primary beneficiary. Therefore, the Company uses the equity method of accounting to record its investment in these joint ventures. For the remaining joint ventures, Columbia Property Trust and its partners have substantive participation rights in the unconsolidated joint ventures, including management selection and termination, and the approval of operating and capital decisions. As such, Columbia Property Trust also uses the equity method of accounting to record its investment in these joint ventures. Under the equity method, investments in unconsolidated joint ventures are recorded at cost and adjusted for cash contributions and distributions, and allocations of income or loss.
Columbia Property Trust evaluates the recoverability of its investments in unconsolidated joint ventures in accordance with accounting standards for equity investments by first reviewing the investment for any indicators of impairment. If indicators are present, Columbia Property Trust estimates the fair value of the investment. If the carrying value of the investment exceeds the estimated fair value, management makes an assessment of whether the deficit is "temporary" or "other-than-temporary," and if "other-than-temporary," reduces the carrying value to reflect the estimated fair value by recording an impairment loss. In making this assessment, management considers the following: (1) the length of time and the extent to which fair value has been less than cost and (2) Columbia Property Trust's intent and ability to retain its interest long enough for a recovery in market value. Based on the analysis described above, Columbia Property Trust has determined that none of its investments in joint ventures are impaired as of September 30, 2020.

6.    Bonds Payable
Columbia Property Trust has two series of bonds outstanding as of September 30, 2020 and December 31, 2019: $350.0 million of 10-year, unsecured 3.650% senior notes issued at 99.626% of their face value (the "2026 Bonds Payable"); and $350.0 million of 10-year, unsecured 4.150% senior notes issued at 99.859% of their face value (the "2025 Bonds Payable"), (collectively, the "Bonds Payable"). Both series of bonds require semi-annual interest payments. The principal amount of the 2026 Bonds Payable is due and payable on August 15, 2026, and the principal amount of the 2025 Bonds Payable is due and payable on April 1, 2025. The Bonds Payable were issued by Columbia OP and are fully and unconditionally guaranteed by Columbia Property Trust, Inc.
Interest payments of $20.0 million were made on the Bonds Payable during both the nine months ended September 30, 2020 and 2019. Columbia Property Trust is subject to substantially similar covenants under the 2026 Bonds Payable and
27


the 2025 Bonds Payable. As of September 30, 2020, Columbia Property Trust was in compliance with the restrictive financial covenants on the 2026 Bonds Payable and the 2025 Bonds Payable.
As of September 30, 2020 and December 31, 2019, the estimated fair value of the Bonds Payable was approximately $735.5 million and $734.4 million, respectively, and the related carrying value, net of discounts, as of September 30, 2020 and December 31, 2019 was $699.0 million and $698.9 million, respectively. The fair value of the Bonds Payable was estimated based on a discounted cash flow analysis, using observable market data for its bonds payable and similar instruments (Level 2). The discounted cash flow method of assessing fair value results in a general approximation of value, which may differ from the price that could be achieved in a market transaction.

7.     Commitments and Contingencies
Commitments Under Existing Lease Agreements
Certain lease agreements include tenant allowances that, at the option of the tenant, may obligate Columbia Property Trust to expend capital to improve an existing property, or to provide other expenditures for the benefit of the tenant.

As of September 30, 2020, the remaining equity contribution requirement is $22.2 million, of which $11.0 million reflects Columbia Property Trust's allocated share. Equity contributions become payable by Columbia Property Trust to the joint venture when a capital call is received. As of September 30, 2020, no capital calls remain unpaid; therefore, no liability has been recorded related to this guaranty.
Commitments Under Real Estate Fund Agreements
Columbia Property Trust's Real Estate Fund investments require capital contributions from time to time. As of September 30, 2020, the Company had $3.6 million of unfunded capital contributions, which are callable for the life of the Real Estate Funds, through 2026.

Litigation
Columbia Property Trust is subject to various legal proceedings, claims, and administrative proceedings arising in the ordinary course of business, some of which are expected to be covered by liability insurance. Management makes assumptions and estimates concerning the likelihood and amount of any reasonably possible loss relating to these matters using the latest information available. Columbia Property Trust records a liability for litigation if an unfavorable outcome is probable, and the amount of loss or range of loss can be reasonably estimated. If an unfavorable outcome is probable and a reasonable estimate of the loss is a range, Columbia Property Trust accrues the best estimate within the range. If no amount within the range is a better estimate than any other amount, Columbia Property Trust accrues the minimum amount within the range. If an unfavorable outcome is probable but the amount of the loss cannot be
28

Table of Contents

reasonably estimated, Columbia Property Trust discloses the nature of the litigation and indicates that an estimate of the loss or range of loss cannot be made. If an unfavorable outcome is reasonably possible and the estimated loss is material, Columbia Property Trust discloses the nature and estimate of the possible loss of the litigation. Columbia Property Trust does not disclose information with respect to litigation where the possibility of an unfavorable outcome is considered to be remote. Based on current expectations, such matters, both individually and in the aggregate, are not expected to have a material adverse effect on the liquidity, results of operations, business, or financial condition of Columbia Property Trust. Columbia Property Trust is not currently involved in any legal proceedings of which management would consider the outcome to be reasonably likely to have a material adverse effect on the results of operations, liquidity, or financial condition of Columbia Property Trust.

11.     Leases
Columbia Property Trust as Lessee
Columbia Property Trust is a lessee on ground leases at certain of its investment properties and office space leases. As of September 30, 2020, Columbia Property Trust has one ground lease at 116 Huntington Avenue in Boston. In August 2020, the Company extended the term of this ground lease to 99 years, expiring in 2119, for a $10.0 million payment. As a result, as of September 30, 2020, Columbia Property Trust's ground lease has a remaining lease term of 98.9 years, inclusive of renewal options, and is included in operating lease assets of $39.5 million. Payments for all future periods under this ground lease have already been made. Thus, as of September 30, 2020, operating lease liabilities of $2.5 million include only the present value of future payments due under two office leases, with a weighted-average remaining lease term of 2.3 years, inclusive of renewal options.
Columbia Property Trust as Lessor
Columbia Property Trust owns and leases commercial real estate, primarily office space, to tenants under operating leases for specified periods of time. Rental income related to such leases is recognized on a straight-line basis over the remaining lease period, and is included in lease revenues on the consolidated statements of operations. As of September 30, 2020, the weighted-average remaining term for such leases is approximately 6.1 years.
Lease revenues include fixed and variable payments. Fixed payments primarily relate to base rent and include payments related to lease terminations; and variable payments primarily relate to tenant reimbursements for certain property operating costs. Fixed and variable payments for the three and nine months ended September 30, 2020 and 2019 are as follows (in thousands):

12.     Non-Lease Revenues
Columbia Property Trust derives most of its revenues from leases, as described in Note 11, Leases. Columbia Property Trust also has the following non-lease revenue streams.
Management Fee Revenue
Under asset and property management agreements in place with third parties and certain of its unconsolidated joint ventures, Columbia Property Trust earns revenue for performing asset and property management functions for properties owned by the Real Estate Funds and its joint ventures, as further described in Note 4, Unconsolidated Joint Ventures, as well as third-party-owned properties. Asset and property management services are ongoing and routine, and are provided on a recurring basis. Therefore such fees are recognized ratably over the service period, usually a period of three months. For the three months ended September 30, 2020 and 2019, Columbia Property Trust earned management fee revenues of $4.1 million and $1.9 million, respectively; and for the nine months ended September 30, 2020 and 2019, Columbia Property Trust earned management fee revenues of $11.4 million and $5.7 million, respectively, under these agreements.
Leasing Fees
Under asset and property management agreements in place with third parties and for certain properties owned by joint ventures and the Real Estate Funds, Columbia Property Trust is eligible to earn leasing fees equal to a percentage of the total rental payments to be made by the tenant over the term of the lease. Such fees are required to be recognized when Columbia Property Trust's obligation to perform is complete, typically upon execution of the lease. For the three months ended September 30, 2020 and 2019, Columbia Property Trust earned leasing override fees of $253,300 and $52,500, respectively; and for the nine months ended September 30, 2020 and 2019, Columbia Property Trust earned leasing override fees of $284,500 and $74,600, respectively. Such fees are included in management fee revenue on the accompanying consolidated statements of operations.
Construction and Development Fee Income
Under construction and development contracts in place with third-party properties and for certain properties owned by joint ventures and the Real Estate Funds, Columbia Property Trust earns fees related to construction and development project management and supervision, using a percentage of completion method, measured by the percentage of costs incurred to date as compared with the estimated total costs for each contract. For the three and nine months ended September 30, 2020, Columbia Property Trust earned construction and development fees of $0.7 million and $2.6 million, respectively. Such fees are included in management fee revenue on the accompanying consolidated statements of operations.
Salary and Other Reimbursement Revenue
Under the property management agreements for third-party-owned properties and certain properties owned through joint ventures and the Real Estate Funds, Columbia Property Trust receives reimbursements for salaries and property operating costs for services that are provided by Columbia Property Trust employees on an ongoing basis. Such reimbursement revenues are recognized ratably over the service period, usually a period of one month, three months, or one year. For the three months ended September 30, 2020 and 2019, Columbia Property Trust earned salary and other reimbursement revenue of $3.6 million and $1.1 million, respectively; and, for the nine months ended September 30, 2020 and 2019, Columbia Property Trust earned salary and other reimbursement revenue of $11.1 million and $3.3 million, respectively. These amounts are included in management fee revenues in 2020, and in other property income in 2019, on the accompanying consolidated statements of operations.
Miscellaneous Revenue
Columbia Property Trust also receives revenues for services provided to its tenants through the TRS Entities, including fitness centers, shuttles, and cafeterias. These revenues are recognized ratably over the service period, usually a period of one month or one quarter. For the three months ended September 30, 2019, Columbia Property Trust earned miscellaneous revenue of $17,900; and for the nine months ended September 30, 2020 and 2019, Columbia Property Trust earned miscellaneous revenue of $7,100 and $253,300, respectively. These amounts are included in other property income on the accompanying consolidated statements of operations.

13.    Earnings Per Share
For the three and nine months ended September 30, 2020 and 2019, in computing the basic and diluted earnings per share, net income (loss) attributable to common stockholders has been reduced for the dividends paid on unvested shares granted under the LTI Plan. The effect of the conversion of the Preferred OP Units to common shares is excluded from the computation of basic and diluted earnings per share because all income (loss) attributable to the Preferred OP Units is recorded as income (loss) attributable to non-controlling interests, thus is excluded from net income (loss) available to common stockholders. The following table reconciles the numerator for the basic and diluted earnings-per-share computations shown on the consolidated statements of operations for the three and nine months ended September 30, 2020 and 2019 (in thousands):

14.    Segment Information
Columbia Property Trust establishes operating segments at the property level and aggregates individual properties into reportable segments for high-barrier-to-entry markets and other geographic locations in which Columbia Property Trust has significant investments. Columbia Property Trust considers geographic location when evaluating its portfolio composition and in assessing the ongoing operations and performance of its properties. As of September 30, 2020, Columbia Property Trust had the following reportable segments:  New York, San Francisco, Washington, D.C., Boston, and all other office markets. The all other office markets reportable segment includes properties that are situated similarly within their geographic markets, typically including sub-markets not located within central business districts, and in which Columbia Property Trust does not have a substantial presence and does not plan to make further investments. Upon selling its remaining properties in Atlanta during 2019 and Los Angeles in March of 2020, Columbia Property Trust has combined Atlanta, Los Angeles, and the all other office markets reportable segment for all periods presented. During the periods presented, there have been no material intersegment transactions.
Net operating income ("NOI") is a non-GAAP financial measure. NOI is the primary performance measure reviewed by management to assess operating performance of properties and is calculated by deducting operating expenses from operating revenues. Operating revenues include lease revenues and other property income; and operating expenses include property operating costs. The NOI performance metric consists only of revenues and expenses directly related to real estate rental operations. NOI reflects property acquisitions and dispositions, occupancy levels, rental rate increases

or decreases, and the recoverability of operating expenses. NOI, as Columbia Property Trust calculates it, may not be directly comparable to similarly titled, but differently calculated, measures for other REITs.
Asset information and capital expenditures by segment are not reported because Columbia Property Trust does not use these measures to assess performance. Depreciation and amortization expense, along with other expense and income items, are not allocated among segments.

ITEM 2.        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis should be read in conjunction with our accompanying consolidated financial statements (and notes thereto) and the "Cautionary Note Regarding Forward-Looking Statements" preceding Part I of this report, as well as our consolidated financial statements (and the notes thereto) and Management's Discussion and Analysis of Financial Condition and Results of Operations included in our 2019 Form 10-K.

Executive Summary
On March 11, 2020, the World Health Organization declared the novel strain of coronavirus (COVID-19) a global pandemic and recommended containment and mitigation measures worldwide. Response to the COVID-19 pandemic led to aggressive actions to reduce the spread of the disease which seriously disrupted activities in large segments of the economy, including in the regional economies where we operate. As some regions of the country have begun to reopen with various restrictions, we are continuing to monitor the COVID-19 pandemic and its impact on our business, tenants, and industry as a whole. We are committed to the health and safety of our employees, tenants, and communities. Because our portfolio is well leased with minimum near-term rollover, and our rent collections level remains high, our operating performance has not materially suffered from the COVID-19 pandemic to date.

The long-term impact of the pandemic on our tenants, demand for office space, and the global economy remains uncertain and will depend on various factors, including the scope, severity, and duration of the pandemic. Sustained work-from-home trends could negatively impact demand for office space in our markets, and consequently could impede our ability to enter into new leases, or to re-lease space as leases rollover. A continued economic downturn and recession could adversely affect many of our tenants which could, in turn, adversely impact our business, financial condition, and results of operations as well. We have worked closely with our impacted tenants and will continue to address their concerns on a case-by-case basis, including arrangements that address cash flow interruptions while maintaining long-term lease obligations. Through September 30, 2020, we have deferred and abated rental billings of $2.7 million and $0.5 million, respectively, including our share of deferrals and abatements made by our unconsolidated joint ventures.

Our primary strategic objective is to generate long-term stockholder returns from a combination of growing cash flows and appreciation in the values of our properties. We own and operate high-quality office properties located in high-barrier-to-entry markets, primarily New York, San Francisco, Washington, D.C., and Boston. Our approach is to own office buildings that are competitive within the top tier of their markets or that will be repositioned as such through value-add initiatives, including development or redevelopment. Our investment objectives include optimizing our portfolio allocation between stabilized investments and more growth-oriented, value-add investments and development projects with an emphasis on central business districts and multi-tenant buildings.
On January 24, 2020, we acquired Normandy, a developer, operator, and investment manager of office and mixed-use assets in New York, Boston, and Washington, D.C., interests in three real estate funds, and contracts to provide real estate services to properties affiliated with those funds. We believe that the acquisition of Normandy furthers our strategic initiatives by strengthening our platform with additional development and redevelopment expertise, deal sourcing, and other key capabilities, and by increasing our access to capital through Normandy's investor relationships.
Over the past several years, we have undertaken a capital recycling program that has involved selling more than 50 properties in geographically dispersed markets for $4.5 billion, and reinvesting those proceeds in our core markets. In January 2020, we sold Cranberry Woods Drive in Pittsburgh for $180.0 million; and in March 2020, we sold Pasadena Corporate Park in Los Angeles for $78.0 million, which marked the exit of our last non-target market. In March 2020, we also acquired an 8.65% interest in Terminal Warehouse, a 1.2-million-square-foot property located in West Chelsea, New York, that will be fully redeveloped into a mixed-use retail and office space, for an initial equity contribution of approximately $40.0 million. Lastly, in October 2020, we expanded an existing joint venture relationship by contributing 221 Main Street to a joint venture partnership, and simultaneously selling a 45% interest therein for $180.0 million.
As of September 30, 2020, the operating properties in our portfolio were 96.3% leased, with 7.9% of our leases scheduled to expire over the next 12 months. During the first nine months of 2020, we leased a total of 227,900 square
37

Table of Contents

feet of space, including a lease renewal and expansion for an aggregate 68,200 square feet at 1800 M Street in Washington, D.C.

As of September 30, 2020, our debt-to-real-estate-asset ratio was 41.7%(1), and approximately 35.2% on a net basis (i.e., reduced for cash on hand)(1). In October 2020, we used $176.0 million of the proceeds from the partial sale of 221 Main Street to repay borrowings on our Revolving Credit Facility. Additionally, as of September 30, 2020, 89%(1) of our portfolio is unencumbered by mortgages; and the weighted-average cost of our consolidated and pro-rata share of joint venture borrowings during the quarter was 3.08%(1) per annum. Our debt maturities are laddered over the next six years, and $951.0 million of our unsecured borrowings can be repaid prior to maturity without penalty.

From time to time when we believe our stock is undervalued, we may take advantage of market opportunities by using our stock repurchase program to buy shares and return capital to our stockholders. During the first nine months of 2020, we repurchased 1.2 million shares at an average price of $19.47 per share, for aggregate purchases of $23.3 million. As of September 30, 2020, $143.3 million remains available under our current repurchase program.
(1)Statistics include 100% of all of our consolidated properties and our ownership interest in the gross real estate assets and debt at properties held through unconsolidated joint ventures as described in Note 4, Unconsolidated Joint Ventures, of the accompanying financial statements.

Key Performance Indicators
Our operating results depend primarily upon the level of income generated by the leases at our properties. Occupancy and rental rates are key drivers of our lease income. Our portfolio was 96.3% leased as of September 30, 2020, and 96.9% leased as of September 30, 2019. The following table sets forth details related to the financial impact of our recent leasing activities for properties we own directly and based on our proportionate share of properties owned through unconsolidated joint ventures:

In 2020, rent leasing spreads (19.4% for the nine months ended September 30, 2020) primarily relate to a 68,200-square-foot lease renewal and expansion at 1800 M Street in Washington, D.C., a 15,500-square-foot office lease renewal at 650 California Street in San Francisco, a 10,100-square-foot office lease renewal at 221 Main Street in San Francisco, and a new 34,800-square-foot lease at 315 Park Avenue South in New York. Current-year tenant improvements ($86.87 per square foot for the nine months ended September 30, 2020) and leasing commissions ($52.92 per square foot for the nine months ended September 30, 2020) primarily relate to the 68,200-square-foot lease

renewal and expansion at 1800 M Street in Washington, D.C., and a new 59,500-square-foot lease at 80 M Street in Washington, D.C. In 2019, rent leasing spreads were positive (77.0% and 73.3% for the three and nine months ended September 30, 2019, respectively) primarily related to a 29,500-square-foot office lease renewal at 218 West 18th Street in New York and a new 15,200-square-foot lease at 650 California Street in San Francisco. Over the next 12 months, approximately 7.9% of the leases in our portfolio are scheduled to expire, based on revenues (no individual tenant comprises more than 2.0%).
Rent Collections and Concessions
Our tenants' businesses and operations have been impacted by the COVID-19 pandemic in a variety of ways. In certain instances, we have provided rent concessions as a temporary measure to address our tenants' near-term cash flow needs. For the second and third quarters, we deferred rents for 10 tenants totaling $2.7 million (1.5% of billings) and abated rents for three tenants totaling $0.5 million (0.2% of billings), including our prorated share of rents earned through unconsolidated joint ventures. Overall, our collections levels remain high and similar to our pre-COVID-19 levels. For the three months ended September 30, 2020, our collection rates are as follows:

Liquidity and Capital Resources
Overview
Cash flows generated from the operation of our properties are primarily used to fund recurring expenditures and stockholder dividends. The amount of distributions to common stockholders is determined by our board of directors and is dependent upon a number of factors, including funds deemed available for distribution based principally on our current and future projected operating cash flows, reduced by capital requirements necessary to maintain our existing portfolio, our future capital needs, and future sources of liquidity, as well as the annual distribution requirements necessary to maintain our status as a REIT under the Code. Investments in new property acquisitions and first-generation capital improvements are generally funded with capital proceeds from property sales, debt, or cash on hand. Our board of directors elected to maintain a $0.21 dividend rate for the third quarter of 2020.
We continue to monitor the developments around COVID-19 and the related impacts to our business. In response to the economic uncertainty that has unfolded as a result of COVID-19, we drew down $200.0 million on our Revolving Credit Facility in late March 2020. On October 13, 2020, we used $176.0 million of the proceeds from the partial sale of 221 Main Street to repay borrowings on our Revolving Credit Facility, and held remaining cash balances of approximately $270.0 million. See Item IA., Risk Factors, for additional information.
Short-Term Liquidity and Capital Resources
During the first nine months of 2020, we generated net cash flows from operating activities of $80.0 million, which consist primarily of receipts from tenants for rent and reimbursements, reduced by payments for operating costs, administrative expenses, interest expense, and lease inducements. During the same period, we paid total distributions to stockholders and Preferred OP Unit holders of $98.5 million, which included dividend payments for four quarters ($24.2 million for fourth quarter of 2019 and $74.3 million for the first three quarters of 2020).
During the first nine months of 2020, we received $250.8 million in aggregate net sales proceeds from the sale of Cranberry Woods Drive and Pasadena Corporate Park and borrowed net proceeds on our Revolving Credit Facility of $167.0 million. These proceeds were used to fund our investment in the Terminal Warehouse Joint Venture ($40.0

million), leasing and capital projects for consolidated and unconsolidated properties ($69.2 million), and redemptions of common stock ($25.5 million). As of September 30, 2020, we had cash on hand of $272.8 million.
Over the short term, we expect our primary sources of capital and liquidity to be operating cash flows and cash on hand, and expect that our principal demands for capital will be to fund development and redevelopment costs, capital improvements to our existing portfolio, stockholder distributions, stock repurchases, operating expenses, and interest and principal payments. As of October 23, 2020, in addition to cash on hand, we have access to additional borrowings of $325.0 million under our Revolving Credit Facility. We believe that we will have adequate liquidity and capital resources to meet our current obligations as they come due.
Long-Term Liquidity and Capital Resources
Over the long term, we expect that our primary sources of capital will include operating cash flows, cash on hand, borrowing proceeds, and select property dispositions. We expect that our primary uses of capital will continue to include stockholder distributions; acquisitions; development and redevelopment costs; capital expenditures, such as building improvements, tenant improvements, and leasing costs; and repaying or refinancing debt.
Consistent with our financing objectives and operational strategy over the long term, we have generally maintained debt levels at less than 40% of the undepreciated costs of our assets; however, due to the amount of cash on hand as of September 30, 2020, our debt-to-real-estate-asset ratio was approximately 41.7% on a gross basis, and approximately 35.2% on a net basis (i.e., reduced for cash on hand). Our debt-to-real-estate-asset ratio includes our share of joint venture real estate assets and debt, as well as basis adjustments related to joint venture real estate assets.
As described below, our variable-rate indebtedness may use London Interbank Offering Rate ("LIBOR") as a benchmark for establishing the rate. LIBOR is expected to be discontinued at the end of 2021. The anticipated discontinuation of LIBOR will require lenders and their borrowers to transition from LIBOR to an alternative benchmark interest rate, which might increase the cost of our variable-interest debt instruments. When LIBOR is discontinued as anticipated, or otherwise at our option, our Revolving Credit Facility and term loan facilities provide for alternate interest rate calculations.
Unsecured Bank Debt
Our Revolving Credit Facility has a capacity of $650.0 million and matures in January 2023, with two six-month extension options. As of September 30, 2020, we had $501.0 million in outstanding borrowings on the Revolving Credit Facility. Amounts outstanding under the Revolving Credit Facility bear interest at either (i) LIBOR, plus an applicable margin ranging from 0.775% to 1.45% for LIBOR borrowings, or (ii) an alternate base rate, plus an applicable margin ranging from 0.00% to 0.45% for base rate borrowings, based on our applicable credit rating. The per annum facility fee on the aggregate revolving commitment (used or unused) ranges from 0.125% to 0.30%, also based on our applicable credit rating. Additionally, the Revolving Credit Facility, along with the $300 Million Term Loan, as described below, provides for four accordion options for an aggregate additional amount of up to $500 million, subject to certain limitations.
Our $300 Million Term Loan matures in January 2024 and bears interest, at our option, at either (i) LIBOR, plus an applicable margin ranging from 0.85% to 1.65% for LIBOR loans, or (ii) an alternate base rate, plus an applicable margin ranging from 0.00% to 0.65% for base rate loans, based on our applicable credit rating. The interest rate on the $300 Million Term Loan is effectively fixed with an interest rate swap agreement, which is designated as a cash flow hedge. Based on the terms of the interest rate swap and our current credit rating, the interest rate on the $300 Million Term Loan is effectively fixed at 2.55%.
Our $150 Million Term Loan matures in July 2022 and bears interest, at our option, at either (i) LIBOR, plus an applicable margin ranging from 0.90% to 1.75% for LIBOR loans, or (ii) alternative base rate, plus an applicable margin ranging from 0.00% to 0.75% for base rate loans. The interest rate on the $150 Million Term Loan is effectively fixed with an interest rate swap agreement, which is designated as a cash flow hedge. Based on the terms of the interest rate swap and our current credit rating, the interest rate on the $150 Million Term Loan is effectively fixed at 3.07%.

Bonds Payable
We have two series of bonds outstanding as of September 30, 2020:
$350.0 million of 10-year, unsecured 4.150% senior notes issued at 99.859% of their face value, maturing on April 1, 2025, which require semi-annual interest payments in April and October (the "2025 Bonds Payable").
$350.0 million of 10-year, unsecured 3.650% senior notes issued at 99.626% of their face value, maturing on August 15, 2026, which require semi-annual interest payments in February and August (the "2026 Bonds Payable").
Columbia OP is the issuer of our Bonds Payable, both series of which are fully and unconditionally guaranteed by Columbia Property Trust. Columbia Property Trust owns 97.2% of Columbia OP, and includes the accounts of Columbia OP in its consolidated financial statements. The primary differences between Columbia Property Trust and Columbia OP are as follows: Columbia Property Trust owns one property directly and has made intercompany loans to subsidiaries of Columbia OP, and Columbia Property Trust – the publicly traded entity – issues publicly traded common stock to investors (including employees) and has engaged in share repurchases from time to time. Columbia Property Trust has contributed the substantial majority of proceeds from sales of its common stock to Columbia OP.
Columbia Property Trust's guarantees of Columbia OP's obligations under the Bonds Payable include the punctual payments of principal, premium, if any, and interest on the Bonds Payable, whether at stated maturity, by declaration of acceleration, call for redemption, or otherwise. The obligations of Columbia Property Trust under its guarantees are limited to the amount necessary to prevent such guarantees from constituting a fraudulent transfer or conveyance under applicable law. The Bonds Payable are Columbia OP's senior unsecured obligations and rank equally in right of payment with all of its other existing and future senior unsecured indebtedness; Columbia Property Trust's guarantees of the Bonds Payable are its senior unsecured obligations and rank equally in right of payment with all of Columbia Property Trust's other existing and future senior unsecured indebtedness and guarantees.
As a result of Columbia Property Trust's guarantees, we are presenting the following summarized financial information (in thousands) for Columbia Property Trust and Columbia OP, pursuant to Rule 13-01 of Regulation S-X, Guarantors and Issuers of Guaranteed Securities Registered or Being Registered. For purposes of the following summarized financial information, transactions between Columbia Property Trust and Columbia OP, presented on a combined basis, have been eliminated, and information for non-guarantor subsidiaries has been excluded.

In addition to the amounts shown, certain lease agreements include provisions that, at the option of the tenant, may obligate us to expend capital to expand an existing property or provide other expenditures for the benefit of the tenant.

Results of Operations
Overview
As of September 30, 2020, our portfolio of 15 operating properties was approximately 96.3% leased.

Comparison of the Three Months Ended September 30, 2020 With the Three Months Ended September 30, 2019
Lease revenues were $72.5 million for the three months ended September 30, 2020, which represents a slight increase as compared with $69.0 million for the three months ended September 30, 2019, as the impacts of fees earned in connection with terminating a lease with WeWork at 149 Madison Avenue in July 2020 ($6.3 million), the acquisition of 201 California Street ($5.4 million), and additional revenues from leasing activity ($4.6 million) are offset by dispositions ($12.7 million). We expect future lease revenues to vary based on recent and future investing and leasing activities.
Management fee revenues were $9.6 million for the three months ended September 30, 2020, which represents an increase as compared with $1.9 million for the three months ended September 30, 2019, due to the Normandy Acquisition in January 2020. In connection with the Normandy Acquisition, we acquired contracts to provide management services to properties affiliated with the Real Estate Funds. Management fee revenues include $3.5 million of reimbursements of salaries and third-party costs recorded as management fee expense. Management fee revenue is expected to remain at a similar level in the near term.
Other property income was $1.1 million for the three months ended September 30, 2019, relating primarily to reimbursements for management fee administration costs, which are recorded as management fee revenues beginning in the first quarter of 2020. Other property operating income is expected to remain at similar levels in the near term.
Property operating costs were $22.0 million for the three months ended September 30, 2020, which represents a slight decrease as compared with $23.2 million for the three months ended September 30, 2019, as the impact of recent dispositions ($1.9 million) and recording of expenses for reimbursed management fee administration costs as management fee expenses beginning in the first quarter of 2020 ($1.1 million) are offset by the acquisition of 201 California Street ($2.1 million). Property operating costs are expected to vary based on recent and future investing and leasing activities.
Depreciation was $17.4 million for the three months ended September 30, 2020, which represents a slight decrease as compared with $19.8 million for the three months ended September 30, 2019, as the impact of recent dispositions ($3.9 million) was partially offset by the acquisition of 201 California Street ($1.7 million). Depreciation is expected to vary based on recent and future investing activities and capital projects.
Amortization was $9.6 million for the three months ended September 30, 2020, which represents an increase as compared with $7.5 million for the three months ended September 30, 2019, as the impacts of the WeWork lease termination at 149 Madison Avenue ($3.2 million) and the acquisition of 201 California Street ($1.3 million) are partially offset by the impact of recent dispositions ($1.7 million). We expect future amortization to vary, based on recent and future investing and leasing activities.
General and administrative – corporate expenses were $11.5 million for the three months ended September 30, 2020, which represents an increase as compared with $7.1 million for the three months ended September 30, 2019, primarily due to the Normandy Acquisition: $3.2 million related to vesting of the Preferred OP Units issued as consideration for the transaction, and $1.0 million related to increased payroll costs. General and administrative – corporate expenses are expected to remain at similar levels in the near term.

Management fee expense was $7.8 million for the three months ended September 30, 2020, which represents an increase as compared with $0.8 million for the three months ended September 30, 2019. For the current period, these expenses reflect salaries and third-party costs incurred to earn management fee revenues by providing management services to properties owned by unconsolidated joint ventures and affiliated with the Real Estate Funds acquired in the Normandy Acquisition. For the prior period, these expenses represent costs incurred to manage assets owned by our unconsolidated joint ventures. Future management fee expenses are expected to vary as a function of management fee revenues.
For the three months ended September 30, 2020 and 2019, we recognized acquisition costs of $0.4 million and $2.4 million, respectively, related to the Normandy Acquisition. These costs include legal, advisory, and other professional services fees related to the acquisition. Future levels of acquisition costs will vary based on future transaction activities.
Interest expense was $9.5 million for the three months ended September 30, 2020, which represents a decrease as compared with $10.3 million for the three months ended September 30, 2019, primarily due to interest capitalization to our development projects. We expect interest expense to decrease in the near term due to repayments on our Revolving Credit Facility.
Interest and other income (expense) was $(0.1) million for the three months ended September 30, 2020, which primarily relates to a market value adjustment to our investments in Real Estate Funds (see Note 2, Summary of Significant Accounting Policies, to the accompanying financial statements). Interest and other income is expected to vary primarily based on future valuation adjustments to our investments in Real Estate Funds.
Income tax expense was $0.4 million for the three months ended September 30, 2020, as a result of the management fee income recognized by our TRS Entities. We expect income tax expense to increase in relation to management fees in future periods.
Income from the unconsolidated joint ventures was $2.0 million for the three months ended September 30, 2020, which represents a slight decrease as compared with $2.2 million for the three months ended September 30, 2019. Losses from Terminal Warehouse, which is under development ($0.4 million) and reduced operating income at our other joint ventures ($0.6 million), are partially offset by income earned from the recently acquired Real Estate Services Joint Ventures ($0.8 million). We expect income from the unconsolidated joint ventures to vary based on future joint venture investing activities and leasing activity at the properties owned through unconsolidated joint ventures.
We recognized a gain on sale of real estate assets of $0.1 million for the three months ended September 30, 2019, related to post-closing adjustments for the sale of One & Three Glenlake Parkway in April 2019. See Note 3, Transactions, of the accompanying consolidated financial statements for additional details. We expect future gains on sales of real estate assets to vary with disposition activity.
Net income attributable to common stockholders was $5.4 million, or $0.05 per basic and diluted share, for the three months ended September 30, 2020, which represents an increase as compared with a net loss of $20.3 million, or $0.17 per basic and diluted share, for the three months ended September 30, 2019. The increase is primarily driven by the prior-period impairment loss on real estate assets ($23.4 million). See "Supplemental Performance Measures" below for our same-store results compared with the prior year. We expect future earnings to vary, primarily as a result of leasing activity at our existing properties and future investing activity.

Comparison of the Nine Months Ended September 30, 2020 With the Nine Months Ended September 30, 2019
Lease revenues were $209.4 million for the nine months ended September 30, 2020, which represents a slight decrease as compared with $210.4 million for the nine months ended September 30, 2019, as the impact of dispositions ($40.5 million) is partially offset by the acquisition of 201 California Street ($16.6 million), current period lease termination fees ($12.8 million), and additional revenues from recent leasing ($10.3 million). We expect future lease revenues to vary based on recent and future investing and leasing activities.
Management fee revenues were $28.3 million for the nine months ended September 30, 2020, which represents an increase as compared with $5.7 million for the nine months ended September 30, 2019, primarily due to the Normandy Acquisition in January 2020. In connection with the Normandy Acquisition, we acquired contracts to provide management services to properties affiliated with the Real Estate Funds. Management fee revenues include $11.0

million of reimbursements of salaries and third-party costs recorded as management fee expense. Management fee revenue is expected to remain at a similar level in the near term.
Other property income was $7,000 for the nine months ended September 30, 2020, which represents a decrease as compared with $4.0 million for the nine months ended September 30, 2019, primarily due to recording reimbursements for management fee administration costs as management fee revenues beginning in the first quarter of 2020 ($3.3 million recognized in 2019) and moving lease termination fees to lease revenues beginning in the second quarter of 2019 ($0.4 million recognized in 2019). Other property operating income is expected to remain at similar levels in the near term.
Property operating costs were $65.9 million for the nine months ended September 30, 2020, which represents a decrease as compared with $70.5 million for the nine months ended September 30, 2019, as the impact of recent dispositions ($7.2 million) and recording expenses for reimbursed management fee administration costs as management fee expenses beginning in the first quarter of 2020 ($2.8 million), are offset by the acquisition of 201 California Street ($6.4 million). Property operating costs are expected to vary based on recent and future investing and leasing activities.
Depreciation was $53.1 million for the nine months ended September 30, 2020, which represents a decrease as compared with $59.5 million for the nine months ended September 30, 2019, as the impact of recent dispositions ($13.0 million) was offset by the acquisition of 201 California Street ($5.0 million) and putting various capital projects into service ($1.6 million). Depreciation is expected to vary based on recent and future investing activities and capital projects.
Amortization was $23.7 million for the nine months ended September 30, 2020, which represents an increase as compared with $22.1 million for the nine months ended September 30, 2019, as the impact of the acquisition of 201 California Street ($4.5 million) and termination fees earned from WeWork at 149 Madison Avenue ($3.3 million) are offset by dispositions ($5.6 million) and leasing activity ($0.7 million). We expect future amortization to vary, based on recent and future investing and leasing activities.
General and administrative – corporate expenses were $34.4 million for the nine months ended September 30, 2020, which represents an increase as compared with $23.7 million for the nine months ended September 30, 2019, primarily due to the Normandy Acquisition: $8.7 million related to vesting of the Preferred OP Units issued as consideration for the transaction, and $1.8 million related to increased payroll costs. General and administrative – corporate expenses are expected to remain at similar levels in the near term.
Management fee expenses were $24.0 million for the nine months ended September 30, 2020, which represents an increase as compared with $2.5 million for the nine months ended September 30, 2019. For the current period, these expenses reflect salaries and third-party costs incurred to earn management fee revenues by providing management services to properties owned by unconsolidated joint ventures and affiliated with the Real Estate Funds acquired in the Normandy Acquisition. For the prior period, these expenses represent costs incurred to manage assets owned by our unconsolidated joint ventures. Future management fee expenses are expected to vary as a function of management fee revenues.
For the nine months ended September 30, 2020 and 2019, we recognized acquisition costs of $12.8 million and $2.4 million related to the Normandy Acquisition, respectively. These costs include legal, advisory, and other professional services fees related to the acquisition. Future levels of acquisition costs will vary based on future transaction activities.
Interest expense was $28.6 million for the nine months ended September 30, 2020, which represents a decrease as compared with $33.3 million for the nine months ended September 30, 2019. The decrease results from interest capitalization on our development projects ($4.7 million). We expect interest expense to decrease in the near term due to repayments on our Revolving Credit Facility.
Interest and other income (expense) was $(0.4) million for the nine months ended September 30, 2020, which represents a decrease as compared with $1,000 for the nine months ended September 30, 2019. The current-period amount primarily relates to the market value adjustment to our investment in Real Estate Funds (see Note 2, Summary of Significant Accounting Policies, to the accompanying financial statements). Interest and other income is expected to vary primarily based on future valuation adjustments to our investments in Real Estate Funds.

Income tax benefit was $2.0 million for the nine months ended September 30, 2020, as a result of the acquisition expenses which are incurred by our TRS Entities. We expect income tax benefit to decrease in relation to acquisition expenses in future periods.
Income from the unconsolidated joint ventures was $6.5 million for the nine months ended September 30, 2020, which represents a slight increase, as compared with $6.2 million for the nine months ended September 30, 2019. Additional income earned from the recently acquired Real Estate Services Joint Ventures ($1.7 million) is offset by current-period losses from Terminal Warehouse, which is under development ($1.5 million). We expect income from the unconsolidated joint ventures to vary based on future joint venture investing activities and leasing activity at the properties owned through unconsolidated joint ventures.
We recognized a gain on sale of real estate assets of $13.4 million for the nine months ended September 30, 2020, for the sale of Cranberry Woods Drive, and we recognized a gain on sale of real estate assets of $42.0 million for the nine months ended September 30, 2019, for the sale of One & Three Glenlake Parkway. See Note 3, Transactions, of the accompanying consolidated financial statements for additional details. We expect future gains on sales of real estate assets to vary with disposition activity.
Net income attributable to common stockholders was $16.7 million, or $0.14 per basic and diluted share, for the nine months ended September 30, 2020, which represents a decrease as compared with a net income of $31.0 million, or $0.26 per basic and diluted share, for the nine months ended September 30, 2019. The decrease is primarily driven by the year-over-year gain on sales of real estate ($28.6 million) and acquisition costs related to the current-year Normandy Acquisition, net of the related tax benefits ($8.4 million), which are partially offset by the prior-year impairment loss on real estate assets ($23.4 million). See "Supplemental Performance Measures" below for our same-store results compared with the prior year. We expect future earnings to vary, primarily as a result of leasing activity at our existing properties and future investing activity.

NOI by Geographic Segment
We consider geographic location when evaluating our portfolio composition and in assessing the ongoing operations and performance of our properties. As of September 30, 2020, we aggregated our properties into the following geographic segments: New York, San Francisco, Washington, D.C., Boston, and all other office markets. All other office markets consists of properties in low-barrier-to-entry geographic locations in which we do not have a substantial presence and do not plan to make further investments. NOI, as presented below, includes our share of properties owned through unconsolidated joint ventures. See Note 14, Segment Information, of the accompanying consolidated financial statements for additional information and a reconciliation from GAAP net income to NOI.
The following table presents NOI by geographic segment (in thousands):

New York
NOI increased in the New York market as a result of lease termination fees earned at 149 Madison Avenue and 315 Park Avenue South and leasing activity (commenced occupancy increased from 96.7% at September 30, 2019 to 98.1% at September 30, 2020).
San Francisco
NOI increased as a result of the December 2019 acquisition of 201 California Street.
Boston
NOI increased due to leasing at 116 Huntington Avenue (commenced occupancy increased from 86.7% at September 30, 2019 to 100% at September 30, 2020).
All other office markets
NOI decreased as a result of the 2019 sales of Lindbergh Center and One & Three Glenlake in Atlanta, the January 2020 sale of Cranberry Woods Drive in Pittsburgh, and the March 2020 sale of Pasadena Corporate Park in suburban Los Angeles.

Supplemental Performance Measures
In addition to net income, we measure our performance using certain non-GAAP metrics, including: (i) Funds From Operations ("FFO"), (ii) Net Operating Income ("NOI"), and (iii) Same Store Net Operating Income ("Same Store NOI"). These supplemental performance measures are commonly used by REIT industry analysts and investors, and are viewed by management to be useful indicators of operating performance principally because they exclude the effects of certain income and expenses that do not reflect the cash-generating capability of our operations. Management believes that the use of FFO, NOI, and Same Store NOI, combined with net income, improves the understanding of operating results of REITs among the investing public and makes comparisons of REIT operating results more meaningful.
Net income is the most comparable GAAP measure to FFO, NOI, and Same Store NOI. Each of these supplemental performance measures excludes expenses that materially impact our overall results of operations and, therefore, should not be considered as a substitute for net income or any other measures derived in accordance with GAAP. Furthermore, these metrics may not be comparable to other similarly titled measures used by other companies.
Funds From Operations
FFO is a non-GAAP measure used by many investors and analysts who follow the real estate industry to measure the performance of an equity REIT. We consider FFO a useful measure of our performance, principally because it excludes the effects of depreciation and amortization of real estate assets. GAAP depreciation and amortization reflect a systematic reduction in the carrying value of real estate assets and, therefore, are not indicative of the actual increase or decrease in the realizable value of real estate assets. We believe that the use of FFO, combined with the required GAAP presentations, is beneficial in improving our investors' understanding of our operating results and allowing for comparisons among other companies who define FFO as we do.
FFO, as defined by the National Association of Real Estate Investment Trusts ("NAREIT"), represents net income (computed in accordance with GAAP), excluding gains or losses on sales of real estate and impairments of real estate assets, and real estate-related depreciation and amortization, after adjustments for unconsolidated partnerships and joint ventures, for both continuing and discontinued operations. We compute FFO in accordance with NAREIT's definition, which may differ from the methodology for calculating FFO, or similarly titled measures, used by other companies, and thus may not be comparable to those presentations.
FFO is not reduced for the amounts needed to fund capital replacements or expansions, debt service obligations, or other commitments and uncertainties, nor is it indicative of funds available to fund our cash needs, including our ability to make distributions. Our presentation of FFO should not be considered as an alternative to net income (computed in accordance with GAAP) or as an indicator of financial performance.

The following significant noncash revenues and expenses are included in our funds from operations:
Straight-line rental income, net:  To recognize rent on a straight-line basis over the lease term, we recognized net straight-line rental income for our wholly owned properties of $5.0 million and $2.0 million for the three months ended September 30, 2020 and 2019, respectively; and $10.5 million and $9.7 million for the nine months ended September 30, 2020 and 2019, respectively. Income from unconsolidated joint ventures includes additional net straight-line rental income of $0.5 million and $0.2 million for the three months ended September 30, 2020 and 2019, respectively; and $1.9 million and $0.9 million for the nine months ended September 30, 2020 and 2019, respectively. 
Amortization of intangible lease assets and liabilities:  To amortize above- and below-market, in-place lease intangible assets (liabilities), we recognized net increases to rental revenues (or decreases to operating expenses) for our wholly owned properties of $(1.7) million and $(1.1) million for the three months ended September 30, 2020 and 2019, respectively; and $(4.5) million and $(3.4) million for the nine months ended September 30, 2020 and 2019. Income from unconsolidated joint ventures includes additional net operating income for amortization of intangible lease assets and liabilities of $(2.9) million and $(2.4) million for the three months ended September 30, 2020 and 2019, respectively; and $(8.5) million and $(7.4) million for both the nine months ended September 30, 2020 and 2019, respectively.
Amortization of deferred financing costs and debt premiums (discounts):  To amortize costs associated with securing debt from third-party lenders over the terms of the respective debt facilities, we recognized noncash interest expense of $0.6 million for both the three months ended September 30, 2020 and 2019; and $1.9 million for both the nine months ended September 30, 2020 and 2019. Income from unconsolidated joint ventures includes additional noncash interest expense of $0.4 million for both the three months ended September 30, 2020 and 2019, and $1.2 million for both the nine months ended September 30, 2020 and 2019.
Net Operating Income
As set forth below, NOI is calculated by deducting property operating costs from rental and other property revenues for continuing operations. As a performance metric consisting of only revenues and expenses directly related to ongoing real estate rental operations, which have been or will be settled in cash, NOI is narrower in scope than FFO.
NOI, as we calculate it, may not be directly comparable to similarly titled, but differently calculated, measures for other REITs. We believe that NOI is another useful supplemental performance measure, as it is an input in many REIT valuation models, and it provides a means by which to evaluate the performance of the properties.
The major factors influencing our NOI are property acquisitions and dispositions, occupancy levels, rental rate increases or decreases, and the recoverability of operating expenses.
49

Table of Contents

Same Store Net Operating Income
We also evaluate the performance of our properties, on a "same-store" basis, using a metric referred to as Same Store NOI. We view Same Store NOI as a useful supplemental performance measure because it improves comparability between periods by eliminating the effects of changes in our operating portfolio. On an individual property basis, Same Store NOI is computed in the same manner as NOI (as described in the preceding section).
Quarter to Date
For the three months ended September 30, 2020, we have defined our same-store portfolio as those properties that have been continuously owned and operated since July 1, 2019 (the first day of the first quarterly period presented).

Election as a REIT
We have elected to be taxed as a REIT under the Code and have operated as such beginning with our taxable year ended December 31, 2003. To qualify as a REIT, we must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of our adjusted taxable income, as defined in the Code, to our stockholders. To the extent that we satisfy the distribution requirement but distribute less than 100% of our REIT taxable income, we would be subject to federal and state corporate income tax on the undistributed income. If we fail to qualify as a REIT in any taxable year, we will then be subject to federal income taxes on our taxable income for that year and for the four years following the year during which qualification is lost, unless the Internal Revenue Service grants us relief under
52

Table of Contents
certain statutory provisions. Such an event could materially affect our net income and net cash available for distribution to our stockholders. However, we believe that we are organized and operate in such a manner as to qualify for treatment as a REIT for federal income tax purposes.
The TRS Entities are wholly owned subsidiaries of Columbia Property Trust and are organized as Delaware limited liability companies. The TRS Entities, among other things, provide services related to asset and property management, construction and development, and other tenant services that Columbia Property Trust, as a REIT, cannot otherwise provide. We have elected to treat the TRS Entities as taxable REIT subsidiaries. We may perform certain additional, noncustomary services for tenants of our buildings through the TRS Entities; however, any earnings related to such services are subject to federal and state income taxes. In addition, for us to continue to qualify as a REIT, we must limit our investments in taxable REIT subsidiaries to 20% of the value of our total assets. Deferred tax assets and liabilities are established for temporary differences between the financial reporting basis and the tax basis of assets and liabilities at the enacted rates expected to be in effect when the temporary differences reverse.
No provisions for federal income taxes have been made in our accompanying consolidated financial statements, other than the provisions relating to the TRS Entities, as we made distributions in excess of or equal to taxable income for the periods presented. We are subject to certain state and local taxes related to property operations in certain locations, which have been provided for in our accompanying consolidated financial statements.

Inflation
We are exposed to inflation risk, as income from long-term leases is the primary source of our cash flows from operations. There are provisions in the majority of our tenant leases that are intended to protect us from, and mitigate the risk of, the impact of inflation. These provisions include rent steps, reimbursement billings for operating expense pass-through charges, real estate tax, and insurance reimbursements on a per-square-foot basis or, in some cases, annual reimbursement of operating expenses above a certain per-square-foot allowance. However, due to the long-term nature of the leases, the leases may not reset frequently enough to fully cover inflation.

Application of Critical Accounting Policies
There have been no material changes in our critical accounting policies from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019. As described in Note 2, Summary of Significant Accounting Policies, to the accompanying consolidated financial statements, we adopted ASC 842 during the quarter ended March 31, 2019.

Commitments and Contingencies
We are subject to certain commitments and contingencies with regard to certain transactions. Refer to Note 7, Commitments and Contingencies, of our accompanying consolidated financial statements for further explanation. Examples of such commitments and contingencies include:
guaranties related to our unconsolidated joint ventures;
commitments to contribute capital to the Real Estate Funds;
obligations under operating leases;
obligations under capital leases;
commitments under existing lease agreements; and
litigation.

Subsequent Event
We have evaluated subsequent events in connection with the preparation of our consolidated financial statements and notes thereto included in this report and noted the partial sale of 221 Main Street, as described in Note 3, Transactions.

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
As a result of certain of our outstanding debt facilities, we are exposed to interest rate changes. Our interest rate risk management objectives are to limit the impact of interest rate changes on earnings and cash flow, primarily through a low to moderate level of overall borrowings. We manage our ratio of fixed- to floating-rate debt with the objective of achieving a mix that we believe is appropriate in light of anticipated changes. We closely monitor interest rates and will continue to consider the sources and terms of our borrowing facilities to determine whether we have appropriately guarded ourselves against the risk of increasing interest rates in future periods. Fluctuations in LIBOR may affect the amount of interest expense we incur on borrowings indexed to LIBOR, such as borrowings under the Revolving Credit Facility, which bears interest at the applicable LIBOR rate, as defined in the credit agreements, plus an applicable margin that is subject to adjustment based on our credit ratings.
Additionally, we have entered into interest rate swaps and may enter into other interest rate swaps, caps, or other arrangements to mitigate our interest rate risk on a related financial instrument. We do not currently enter into derivative or interest rate transactions for speculative purposes; however, at times certain of our derivatives may not qualify for hedge accounting treatment. All of our debt was entered into for other-than-trading purposes.
Our financial instruments consist of both fixed-rate and variable-rate debt. Our variable-rate borrowings consist of the Revolving Credit Facility, the $300 Million Term Loan, and the $150 Million Term Loan. However, as of September 30, 2020, only borrowings under the Revolving Credit Facility bear interest at effectively variable rates, as the variable rate on the $150 Million Term Loan and $300 Million Term Loan have been effectively fixed through the interest rate swap agreement described in the "Liquidity and Capital Resources" section of Item 2, Management's Discussion and Analysis of Financial Condition and Results of Operations.
As of September 30, 2020, we had $501.0 million in outstanding borrowings under the Revolving Credit Facility; $300.0 million in outstanding borrowings on the $300 Million Term Loan; $150.0 million outstanding on the $150 Million Term Loan; $349.8 million in 2025 Bonds Payable outstanding; and $349.2 million in 2026 Bonds Payable outstanding. The amounts outstanding on our Revolving Credit Facility in the future will largely depend upon future acquisition and disposition activity. The weighted-average interest rate of all our consolidated debt instruments was 2.70% as of September 30, 2020.
Approximately $1,149.0 million of total consolidated debt outstanding as of September 30, 2020 is subject to fixed rates, either directly or when coupled with an interest rate swap agreement. As of September 30, 2020, these balances incurred interest expense at an average interest rate of 3.44% and have expirations ranging from 2022 through 2026. A change in the market interest rate impacts the net financial instrument position of our fixed-rate debt portfolio; however, it has no impact on interest incurred or cash flows.
Approximately $501.0 million of total consolidated debt outstanding as of September 30, 2020, is subject to variable rates. As of September 30, 2020, these balances incurred interest expense at an average interest rate of 1.01% and expire in 2023. An increase or decrease of 100 basis points would have a $5.0 million annual impact on our interest payments.
Our unconsolidated borrowings consist of a fixed-rate mortgage note, a variable-rate construction note, and a variable-rate acquisition note. The Market Square Joint Venture holds a $325 million mortgage note, which bears interest at a fixed rate of 5.07%; the 799 Broadway Joint Venture holds a $135.6 million construction note, which bears interest at a floating rate of 5.25%; and the Terminal Warehouse Joint Venture holds a $643.1 million note, which bears interest at a floating rate of 5.68% as of September 30, 2020. Our weighted-average interest rate of debt, including all consolidated borrowings and our ownership share of debt held by the aforementioned unconsolidated joint ventures, was 3.08% at September 30, 2020.

ITEM 4.        CONTROLS AND PROCEDURES
Management's Conclusions Regarding the Effectiveness of Disclosure Controls and Procedures
We carried out an evaluation, under the supervision and with the participation of management, including the Principal Executive Officer and Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(e) under the Securities Exchange Act of 1934 as of the end of the period covered by this report. Based upon that evaluation, the Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report in providing a reasonable level of assurance that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods in SEC rules and forms, including providing a reasonable level of assurance that information required to be disclosed by us in such reports is accumulated and communicated to our management, including our Principal Executive Officer and our Principal Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control Over Financial Reporting
There have been no changes in our internal control over financial reporting during the quarter ended September 30, 2020, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

From time to time, we are party to legal proceedings which arise in the ordinary course of our business. We are not currently involved in any legal proceedings of which the outcome is reasonably likely to have a material adverse effect on our results of operations, liquidity, or financial condition, nor are we aware of any such legal proceedings contemplated by governmental authorities.

ITEM 1A.RISK FACTORS
The following additional risk factor updates the "Risk Factors" section of our Annual Report on Form 10-K for the year ended December 31, 2019:
Our business has been, and will continue to be, adversely affected by the COVID-19 pandemic.
On March 11, 2020, the World Health Organization announced that the outbreak of the novel coronavirus (COVID-19) had become a pandemic. Federal, state, and local authorities and health officials implemented aggressive actions to reduce the spread of the disease, including limiting non-essential gatherings of people, ceasing all non-essential travel, and issuing "social or physical distancing" guidelines, "shelter-in-place" orders, and mandatory closures for non-essential businesses. Although many (but not all) of these restrictions have been gradually lifted, it remains unclear whether an initial surge in the level of business activity is likely to be sustained, especially if the areas in which our properties are located experience a resurgence in COVID-19 cases and/or are subject to a re-imposition of previously lifted business restrictions.
The COVID-19 pandemic and the measures put in place to address it continue to negatively impact the global economy, disrupt consumer spending and global supply chains, and create significant volatility and disruption of financial markets. The extent of the impact of the COVID-19 pandemic on our business remains highly uncertain and difficult to predict. The extent to which the COVID-19 pandemic ultimately impacts our business, results of operations, financial condition, and stock price will depend on numerous evolving factors, including: the duration and scope of the pandemic; governments', businesses', and individuals' actions taken in response to the pandemic; the impact on economic activity from the pandemic and actions taken in response; changes in demand for office space based on changes in work-from-home trends; the effect on our tenants and their businesses; the ability of tenants to pay their rental income and any closures of our tenants' facilities, including, without limitation, due to shutdowns and "shelter-in-place" orders that have been requested or mandated by governmental authorities; the effect of the pandemic on our construction, development, and redevelopment activities; and the impact on our employees and any other operational disruptions or difficulties we may face. Any of these factors and risks could materially adversely impact our business, financial condition, results of operations, or stock price.

In addition to the general economic impact of the pandemic, if an outbreak of COVID-19 occurs within the workforce of our tenants or otherwise disrupts their management and other personnel, the business and operating results of our tenants could be negatively impacted. The imposition of early "social or physical distancing" guidelines, "shelter-in-place" orders, and mandatory closures have caused some of our retail and restaurant tenants to close for an extended period of time or indefinitely, or to operate at significantly reduced capacity. The negative impact upon our tenants may include an immediate reduction in cash flow available to pay rent under our leases, and although various governmental financial programs may mitigate this, governmental assistance may not be available to all affected tenants or may be significantly delayed or discontinued. In turn, our tenants' inability to pay rent under our leases could adversely affect our own liquidity, and there can be no guarantee that additional liquidity will be readily available or available on favorable terms in the future. For example, in response to the economic uncertainty that has unfolded as a result of COVID-19, we drew down $200.0 million on our Revolving Credit Facility in March 2020 and may need to rely on our lines of credit again in the future, depending on the severity of the pandemic. Several of our tenants have requested rent relief because of the impact of the COVID-19 pandemic on their businesses. Through September 30, 2020, we had executed three rent abatements totaling $0.5 million and 10 rent deferrals totaling $2.7 million, including our share of abatements and deferrals made by our unconsolidated joint ventures. In July 2020, we terminated a lease with WeWork at 149 Madison in New York and received a termination fee of $6.4 million. As a result of the termination, we assumed

full control of the property, including the improvements WeWork had completed to date, and our $18.7 million remaining capital funding obligation was cancelled. We also amended two other leases with WeWork, which resulted in abating rents of $6.7 million ($0.6 million to be applied in 2020, and the remainder to be applied monthly through February 2029, provided the tenant is not in default). As the impact of the pandemic continues, other tenants may request rent relief or seek to renegotiate the terms of their contracts with us, which may adversely affect our operating results and could result in additional lease terminations.

Large-scale executive orders and other measures taken to curb the spread of COVID-19 may also negatively impact the ability of our properties to continue to obtain necessary goods and services or provide adequate staffing, which may also adversely affect our operating results and reputation. Such orders could also impact our ability to commence or continue construction, development, and redevelopment activities, which could result in delays, increased costs, and potentially missed deadlines. Any increased costs or lost revenue as a result of tenant financial difficulty, or their need to comply with executive orders and other guidance from the Centers for Disease Control and Prevention, may not be fully recoverable under our leases or adequately covered by insurance, which could impact our profitability. In addition to the potential consequences listed above, these same factors may cause prospective tenants to delay their leasing decisions or to lease less space. Even after the pandemic has ceased to be active, the prevalence of work-from-home policies during the pandemic may alter tenant preferences in the long term with respect to the demand for leasing office space.
