JBG SMITH PROPERTIES

Notes to Condensed Consolidated and Combined Financial Statements

September 30, 2017

(Unaudited)

1.    Organization and Basis of Presentation

Organization

JBG SMITH Properties ("JBG SMITH") was organized by Vornado Realty Trust ("Vornado" or "former parent") as a Maryland real estate investment trust ("REIT") on October 27, 2016 (capitalized on November 22, 2016). JBG SMITH was formed for the purpose of receiving, via the spin-off on July 17, 2017 (the "Separation"), substantially all of the assets and liabilities of Vornado’s Washington, DC segment, which operated as Vornado / Charles E. Smith, (the "Vornado Included Assets"). On July 18, 2017, JBG SMITH acquired the management business and certain assets and liabilities (the "JBG Assets") of The JBG Companies (the "Combination"). The Separation and the Combination are collectively referred to as the "Formation Transaction." Unless the context otherwise requires, all references to "we," "us," and "our," refer to the Vornado Included Assets, our predecessor and accounting acquirer, for periods prior to the Separation and to JBG SMITH for periods from and after the Separation and Combination.

Prior to the Separation from Vornado, JBG SMITH was a wholly owned subsidiary of Vornado and had no material assets or operations. Pursuant to a separation agreement, on July 17, 2017, Vornado distributed 100% of the then outstanding common shares of JBG SMITH on a pro rata basis to the holders of its common shares. Prior to such distribution by Vornado, Vornado Realty L.P. ("VRLP"), Vornado's operating partnership, distributed common limited partnership units ("OP Units") in JBG SMITH Properties LP ("JBG SMITH LP"), our operating partnership, on a pro rata basis to the holders of VRLP's common limited partnership units, consisting of Vornado and the other common limited partners of VRLP. Following such distribution by VRLP and prior to such distribution by Vornado, Vornado contributed to JBG SMITH all of the OP Units it received in exchange for common shares of JBG SMITH. Each Vornado common shareholder received one JBG SMITH common share for every two Vornado common shares held as of the close of business on July 7, 2017 (the "Record Date").  Vornado and each of the other limited partners of VRLP received one JBG SMITH LP OP Unit for every two common limited partnership units in VRLP held as of the close of business on the Record Date. Our operations are presented as if the transfer of the Vornado Included Assets had been consummated prior to all historical periods presented in the accompanying condensed consolidated and combined financial statements at the carrying amounts of such assets and liabilities reflected in Vornado’s books and records.

In connection with the Separation, JBG SMITH issued 94.7 million common shares and JBG SMITH LP issued 5.8 million OP Units to parties other than JBG SMITH. In connection with the Combination, JBG SMITH issued 23.3 million common shares and JBG SMITH LP issued 13.9 million OP Units to parties other than JBG SMITH. As of the completion of the Formation Transaction there were 118.0 million JBG SMITH common shares outstanding and 19.8 million JBG SMITH LP OP Units outstanding that were owned by parties other than JBG SMITH. As of July 18, 2017 and September 30, 2017, we, as its sole general partner controlled JBG SMITH LP and owned 85.6% of its OP Units.

We own and operate a portfolio of high-quality office and multifamily assets, many of which are amenitized with ancillary retail. Our portfolio reflects our longstanding strategy of concentrating in downtown Washington, DC and other leading urban-infill submarkets with proximity to downtown Washington, DC that have high barriers to entry and key urban amenities, including being within walking distance of a Metro station. 

As of September 30, 2017, our portfolio comprised: (i) 69 operating assets comprising 51 office assets totaling over 13.7 million square feet (11.8 million square feet at our share), 14 multifamily assets totaling 6,016 units (4,232 units at our share) and four other assets totaling approximately 765,000 square feet (348,000 square feet at our share); (ii) nine assets under construction comprising four office assets totaling approximately 1.3 million square feet (1.2 million square feet at our share), four multifamily assets totaling 1,334 units (1,149 units at our share) and one other asset totaling approximately 41,100 square feet (4,100 square feet at our share; (iii) one near-term development multifamily asset totaling 433 units (303 units at our share), and (iv) 42 future development assets totaling approximately 21.3 million square feet (17.6 million square feet at our share) of estimated potential development density.

Our revenues are derived primarily from leases with office and multifamily tenants, including fixed rents and reimbursements from tenants for certain expenses such as real estate taxes, property operating expenses, and repairs and maintenance. In addition to our portfolio, we have a third-party real estate services business that provides fee-based real estate services to our real estate ventures, legacy funds formerly organized by JBG ("JBG Legacy Funds") and other third parties.

Only the U.S. federal government accounted for 10% or more of our rental revenue for the three and nine months ended September 30, 2017 and 2016, as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,
(Dollars in thousands)	2017			2016			2017			2016
U.S. federal government	$	22,492		$	27,594		$	68,869		$	74,939
Percentage of office segment revenue	22.6		%	30.5		%	25.3		%	28.5		%
Percentage of total rental revenue	17.8		%	24.3		%	20.0		%	22.9		%

Basis of Presentation

The accompanying unaudited condensed consolidated and combined financial statements and notes are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions of Form 10-Q and Article 10 of Regulation S-X. Accordingly, these unaudited condensed consolidated and combined financial statements do not contain certain information required in annual financial statements and notes as required under GAAP. In our opinion, all adjustments considered necessary for a fair presentation have been included, and all such adjustments are of a normal recurring nature. All intercompany transactions and balances have been eliminated. The results of operations for the three and nine months ended September 30, 2017 and 2016 are not necessarily indicative of the results that may be expected for a full year. These condensed consolidated and combined financial statements should be read in conjunction with our Registration Statement on Form 10, as amended, filed with the Securities and Exchange Commission (the "SEC") and declared effective on June 26, 2017 as well as the final Information Statement filed with the SEC as Exhibit 99.1 to our Current Report on Form 8-K filed on June 27, 2017.

The accompanying condensed consolidated and combined financial statements include the accounts of JBG SMITH and our wholly-owned subsidiaries and those other entities in which we have a controlling financial interest, including where we have been determined to be a primary beneficiary of a variable interest entity ("VIE"). See Note 6 for more information on our consolidated VIEs. The portions of the equity and net (loss) income of consolidated subsidiaries that are not attributable to JBG SMITH are presented separately as amounts attributable to noncontrolling interests in the condensed consolidated and combined financial statements.

Combination

JBG SMITH and the Vornado Included Assets were under common control of Vornado for all periods prior to the Separation at July 17, 2017. The transfer of the Vornado Included Assets from Vornado to JBG SMITH was completed prior to the Separation, at net book values (historical carrying amounts) carved out from Vornado’s books and records. For purposes of the formation of JBG SMITH, the Vornado Included Assets were designated as the predecessor and the accounting acquirer of JBG SMITH. Consequently, the financial statements of JBG SMITH, as set forth herein, represent a continuation of the financial information of the Vornado Included Assets as the predecessor and accounting acquirer such that the historical financial information included herein as of any date or for any periods on or prior to the completion of the Combination represents the pre-Combination financial information of the Vornado Included Assets. The financial statements reflect the common shares as of the date of the Separation as outstanding for all prior periods prior to July 17, 2017. The acquisition of the management business and certain assets and liabilities of JBG completed subsequently by JBG SMITH was accounted for as a business combination using the acquisition method whereby identifiable assets acquired and liabilities assumed are recorded at the acquisition-date fair values and income and cash flows from the operations were consolidated into the financial statements of JBG SMITH commencing July 18, 2017.

The accompanying condensed consolidated and combined statements of operations for the three and nine months ended September 30, 2017 include our consolidated accounts and the combined accounts of the Vornado Included Assets. Accordingly, the results of operations for the three and nine months ended September 30, 2017 reflect the aggregate operations and changes in cash flows and equity on a combined basis for all periods prior to July 17, 2017 and on a consolidated basis for all periods subsequent to July 17, 2017. The accompanying condensed combined financial statements for the three and nine months ended September 30, 2016 include the Vornado Included Assets. Therefore, the discussion of our results of operations, cash flows and financial condition set forth in this report is not necessarily indicative of our future results of operations, cash flows or financial condition as an independent, publicly traded company.

References to the financial statements refer to our condensed consolidated and combined financial statements as of September 30, 2017 and December 31, 2016, and for the three and nine months ended September 30, 2017 and 2016. References to the balance sheets refer to our condensed consolidated and combined balance sheets as of September 30, 2017 and December 31, 2016. References to the statement of operations refer to our condensed consolidated and combined statements of operations for the three

and nine months ended September 30, 2017 and 2016. References to the statement of cash flows refer to our condensed consolidated and combined statements of cash flows for the nine months ended September 30, 2017 and 2016.

The historical financial results for the Vornado Included Assets reflect charges for certain corporate costs allocated by the former parent which we believe are reasonable. These charges were based on either actual costs incurred or a proportion of costs estimated to be applicable to the Vornado Included Assets based on an analysis of key metrics, including total revenues. Such costs do not necessarily reflect what the actual costs would have been if JBG SMITH had been operating as a separate standalone public company. These charges are discussed further in Note 17.

Recasting of 2016 Financial Information

The historical financial information of the Vornado Included Assets was recast to exclude Vornado's interest in Rosslyn Plaza as it was omitted from the Separation. Financial information disclosed herein as of any date or for any periods on or prior to the completion of the Separation represents such recast amounts.

Reclassifications

Certain prior period data have been reclassified to conform to the current period presentation as follows:

• Reclassification of $4.0 million of investments to "Other assets" on our balance sheet as of December 31, 2016 as a result of the revision in the line item "Investments in and advances to unconsolidated real estate ventures" on our balance sheet to include only real estate investments.

• Reclassification of $4.8 million and $14.3 million of expenses for the three and nine months ended September 30, 2016, respectively, to “General and administrative: third-party real estate services” from “Property operating expenses” as it relates to known expenses incurred to operate our third-party real estate services. Additionally, we reclassified $2.0 million and $6.0 million of income for the three and nine months ended September 30, 2016, respectively, to “Third-party real estate services, including reimbursements” from “Other income” as it relates to revenue earned from our third-party business.

2.    Summary of Significant Accounting Policies

Use of Estimates

The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Business Combinations

We account for business combinations, including the acquisition of real estate, using the acquisition method by recognizing and measuring the identifiable assets acquired, liabilities assumed, and any noncontrolling interests in the acquiree at their acquisition date fair values. As a result, upon the acquisition, we estimate the fair value of the acquired tangible assets (consisting of real estate, cash and cash equivalents, tenant and other receivables, investments in unconsolidated real estate ventures and other assets, as applicable), identified intangible assets and liabilities (consisting of the value of in-place leases, above- and below-market leases, options to enter into ground lease and management contracts, as applicable), assumed debt and other liabilities, and noncontrolling interests, as applicable, based on our evaluation of information and estimates available at that date. Based on these estimates, we allocate the purchase price to the identified assets acquired and liabilities assumed. Any excess of the purchase price over the estimated fair value of the net assets acquired is recorded as goodwill. Any excess of the fair value of assets acquired over the purchase price is recorded as a gain on bargain purchase. If, up to one year from the acquisition date, information regarding the fair value of the net assets acquired and liabilities assumed is received and estimates are refined, appropriate adjustments are made on a prospective basis to the purchase price allocation, which may include adjustments to identified assets, assumed liabilities, and goodwill or the gain on bargain purchase, as applicable. Transaction costs related to business combinations are expensed as incurred and included in "Transaction and other costs" in our statements of operations.

The fair values of tangible real estate assets are determined using the “as-if vacant” approach whereby we use discounted income, or cash flow models with inputs and assumptions that we believe are consistent with current market conditions for similar assets. The most significant assumptions in determining the allocation of the purchase price to tangible assets are the exit capitalization rate, discount rate, estimated market rents and hypothetical expected lease-up periods.

9

The fair values of identified intangible assets are determined based on the following:

• The value allocable to the above- or below-market component of an acquired in-place lease is determined based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between (i) the contractual amounts to be received pursuant to the lease over its remaining term and (ii) management’s estimate of the amounts that would be received using market rates over the remaining term of the lease. Amounts allocated to above- market leases are recorded as "Identified intangible assets" in "Other assets, net" in the balance sheets, and amounts allocated to below-market leases are recorded as "Lease intangible liabilities" in "Other liabilities, net" in the balance sheets. These intangibles are amortized to "Property rentals" in our statements of operations over the remaining terms of the respective leases.

• Factors considered in determining the value allocable to in-place leases include estimates, during hypothetical lease-up periods, related to space that is actually leased at the time of acquisition. These estimates include (i) lost rent at market rates, (ii) fixed operating costs that will be recovered from tenants and (iii) theoretical leasing commissions required to execute similar leases. These intangible assets are recorded as "Identified intangible assets" in "Other assets, net" in the balance sheets and are amortized over the remaining term of the existing lease.

• The fair value of the in-place property management, leasing, asset management, and development and construction management contracts is based on revenue and expense projections over the estimated life of each contract discounted using a market discount rate. These management contract intangibles are amortized over the weighted average life of the management contracts.

The fair value of investments in unconsolidated real estate ventures and related noncontrolling interests is based on the estimated fair values of the identified assets acquired and liabilities assumed of each entity.

The fair value of the mortgages payable assumed was determined using current market interest rates for comparable debt financings. The fair values of the interest rate swaps and caps are based on the estimated amounts we would receive or pay to terminate the contract at the reporting date and are determined using interest rate pricing models and observable inputs. The carrying value of cash, restricted cash, working capital balances, leasehold improvements and equipment, and other assets acquired and liabilities assumed approximates fair value.

The results of operations of acquisitions are included in our financial statements as of the dates they are acquired. The intangible assets and liabilities associated with acquisitions are included in "Other assets, net" and "Other liabilities, net", respectively, in our balance sheets.

Real Estate

Real estate is carried at cost, net of accumulated depreciation and amortization. Maintenance and repairs are expensed as incurred. As real estate is undergoing redevelopment activities, all property operating expenses directly associated with and attributable to the redevelopment, including interest expense, are capitalized to the extent that we believe such costs are recoverable through the value of the property. The capitalization period begins when redevelopment activities are underway and ends when the project is substantially complete. General and administrative costs are expensed as incurred. Depreciation requires an estimate by management of the useful life of each property and improvement as well as an allocation of the costs associated with a property to its various components. Depreciation is recognized on a straight‑line basis over estimated useful lives, which range from three to 40 years. Tenant allowances are amortized on a straight‑line basis over the lives of the related leases, which approximate the useful lives of the tenant improvements.

Construction in progress, including land, is carried at cost, and no depreciation is recorded. Real estate undergoing significant renovations and improvements is considered under development. All direct and indirect costs related to development activities are capitalized into "Construction in progress, including land" on our balance sheets, except for certain demolition costs, which are expensed as incurred. Costs incurred include pre-development expenditures directly related to a specific project, development and construction costs, interest, insurance and real estate taxes. Indirect development costs include employee salaries and benefits, travel and other related costs that are directly associated with the development real estate. Our method of calculating capitalized interest expense is based upon applying our weighted average borrowing rate to the actual accumulated expenditures if the property does not have property specific debt. The capitalization of such expenses ceases when the real estate is ready for its intended use, but no later than one-year from substantial completion of major construction activity. If we determine that a project is no longer viable, all pre-development project costs are immediately expensed. Similar costs related to properties not under development are expensed as incurred.

Our assets and related intangible assets are individually reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment exists when the carrying amount of an asset exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. Estimates

10

of future cash flows are based on our current plans, intended holding periods and available market information at the time the analyses are prepared. An impairment loss is recognized only if the carrying amount of the asset is not recoverable and is measured based on the excess of the property’s carrying amount over its estimated fair value. If our estimates of future cash flows, anticipated holding periods, or fair values change, based on market conditions or otherwise, our evaluation of impairment charges may be different and such differences could be material to our financial statements. Estimates of future cash flows are subjective and are based, in part, on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results.

Real Estate Held for Sale

Real estate held for sale is recorded at the lower of the carrying amount or the expected sales price less costs to sell. Operations of real estate held for sale and real estate sold are reported in continuing operations if their disposition does not represent a strategic shift that has or will have a major effect on our operations and financial results.

The application of the accounting principles that govern the classification any of our real estate as held for sale requires management to make certain significant judgments. In evaluating whether real estate meets the held for sale criteria set forth by the Property, Plant and Equipment Topic of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC"), we make a determination as to the point in time that it is probable that a sale will be consummated. Given the nature of all real estate sales contracts, it is not unusual for such contracts to allow potential buyers a period of time to evaluate the property prior to formal acceptance of the contract. In addition, certain other matters critical to the final sale, such as financing arrangements, often remain pending even upon contract acceptance. As a result, real estate under contract may not close within the expected time period or may not close at all. Therefore, any real estate categorized as held for sale represents only those properties that management has determined are probable to close within the requirements set forth in the Property, Plant and Equipment Topic of the FASB ASC.

We do not have any real estate classified as held for sale as of September 30, 2017 and December 31, 2016.

Cash and Cash Equivalents

Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less and are carried at cost, which approximates fair value, due to their short‑term maturities.

Restricted Cash

Restricted cash consists primarily of security deposits held on behalf of our tenants, cash escrowed under loan agreements for debt service, real estate taxes, property insurance and capital improvements.

Allowance for Doubtful Accounts

We periodically evaluate the collectability of amounts due from tenants, including the receivable arising from deferred rent receivable, and maintain an allowance for doubtful accounts for the estimated losses resulting from the inability of tenants to make required payments under lease agreements. We exercise judgment in establishing these allowances and consider payment history and current credit status in developing these estimates.

Investments in and Advances to Real Estate Ventures

We analyze our real estate ventures to determine whether the respective entities should be consolidated. If it is determined that these investments do not require consolidation because the entities are not VIEs in accordance with the Consolidation Topic of the FASB ASC, we are not considered the primary beneficiary of the entities determined to be VIEs, we do not have voting control, and/or the limited partners (or non-managing members) have substantive participatory rights, then the selection of the accounting method used to account for our investments in unconsolidated real estate ventures is generally determined by our voting interests and the degree of influence we have over the entity. Management uses its judgment when determining if we are the primary beneficiary of, or have a controlling financial interest in, an entity in which we have a variable interest. Factors considered in determining whether we have the power to direct the activities that most significantly impact the entity’s economic performance include risk and reward sharing, experience and financial condition of the other partners, voting rights, involvement in day-to-day capital and operating decisions and the extent of our involvement in the entity.

We use the equity method of accounting for investments in unconsolidated real estate ventures when we own 20% or more of the voting interests and have significant influence but do not have a controlling financial interest, or if we own less than 20% of the voting interests but have determined that we have significant influence. Under the equity method, we record our investments in and advances to these entities in our balance sheets, and our proportionate share of earnings or losses earned by the real estate venture is recognized in "(Loss) income of unconsolidated real estate ventures" in the accompanying statements of operations. We earn revenues from the management services we provide to unconsolidated entities. These fees are determined in accordance with the terms specific to each arrangement and may include property and asset management fees or transactional fees for leasing,

11

acquisition, development and construction, financing, and legal services provided. We account for this revenue gross of our ownership interest in each respective real estate venture and recognize such revenue in "Third-party real estate services, including reimbursements" in our statements of operations. Our proportionate share of related expenses is recognized in "(Loss) income of unconsolidated real estate ventures" in our statements of operations. We may also earn incremental promote distributions if certain financial return benchmarks are achieved upon ultimate disposition of the underlying properties. Management fees are recognized when earned, and promote fees are recognized when certain earnings events have occurred, and the amount is determinable and collectible. Any promote fees are reflected in "(Loss) income from unconsolidated real estate ventures" in our statements of operations.

On a periodic basis, we evaluate our investments in unconsolidated entities for impairment. We assess whether there are any indicators, including underlying property operating performance and general market conditions, that the value of our investments in unconsolidated real estate ventures may be impaired. An investment in a real estate venture is considered impaired only if we determine that its fair value is less than the net carrying value of the investment in that real estate venture on an other-than-temporary basis. Cash flow projections for the investments consider property level factors such as expected future operating income, trends and prospects, as well as the effects of demand, competition and other factors. We consider various qualitative factors to determine if a decrease in the value of our investment is other-than-temporary. These factors include age of the venture, our intent and ability to retain our investment in the entity, financial condition and long-term prospects of the entity and relationships with our partners and banks. If we believe that the decline in the fair value of the investment is temporary, no impairment charge is recorded. If our analysis indicates that there is an other-than temporary impairment related to the investment in a particular real estate venture, the carrying value of the venture will be adjusted to an amount that reflects the estimated fair value of the investment.

Intangibles

Intangible assets consist of in-place leases, below-market ground rent obligations, above-market real estate leases, lease origination costs and options to enter into ground lease that were recorded in connection with the acquisition of properties. Intangible assets also include management and leasing contracts acquired as part of the Combination. Intangible liabilities consist of above-market ground rent obligations and below-market real estate leases that are also recorded in connection with the acquisition of properties. Both intangible assets and liabilities are amortized and accreted using the straight-line method over their applicable remaining useful life. When a lease or contract is terminated early, any remaining unamortized or unaccreted balances are charged to earnings. The useful lives of intangible assets are evaluated each reporting period with any changes in estimated useful lives being accounted for over the revised remaining useful life.

Deferred Costs

Deferred financing costs consist of loan issuance costs directly related to financing transactions that are deferred and amortized over the term of the related loan as a component of interest expense. Unamortized deferred financing costs related to our mortgages payable and unsecured term loan are presented as a direct deduction from the carrying amounts of the related debt instruments, while such costs related to our revolving credit facility are included in other assets.

Direct salaries, third-party fees and other costs incurred by us to originate a lease are capitalized in "Other assets, net" in the balance sheets and are amortized against the respective leases using the straight-line method over the term of the related leases.

Noncontrolling Interests

Redeemable noncontrolling interests consists of OP Units issued in conjunction with the Formation Transaction. The OP Units are redeemable for our common shares or cash beginning August 1, 2018, subject to certain limitations. Redeemable noncontrolling interests are generally redeemable at the option of the holder and are presented in the mezzanine section between total liabilities and shareholders' equity on the balance sheets. The carrying amount of redeemable noncontrolling interests is adjusted to its redemption value at the end of each reporting period, but no less than its initial carrying value, with such adjustments recognized in "Additional paid-in capital".

Noncontrolling interests in consolidated subsidiaries represents the portion of equity that we do not own in entities we consolidate, including interests in consolidated real estate ventures or VIEs in connection with property acquisitions. We identify our noncontrolling interests separately within the equity section on the balance sheets. See Note 10 for further information.

Amounts of consolidated net (loss) income attributable to redeemable noncontrolling interests and to the noncontrolling interests in consolidated subsidiaries are presented separately in the statements of operations.

Derivative Financial Instruments and Hedge Accounting

Derivative financial instruments are used at times to manage exposure to variable interest rate risk. Derivative financial instruments, consisting of interest rate swaps and caps, are considered economic hedges, but not designated as accounting hedges, and are

12

carried at their estimated fair value on a recurring basis. Realized and unrealized gains are recorded in "Interest and other (loss) income, net" in the statements of operations in the period in which the change occurs.

Fair Value of Assets and Liabilities

ASC 820, Fair Value Measurement and Disclosures, defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels:

Level 1 — quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities;

Level 2 — observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and

Level 3 — unobservable inputs that are used when little or no market data is available.

The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value.

Revenue Recognition

Property rentals income includes base rents that each tenant pays in accordance with the terms of its respective lease and is reported on a straight-line basis over the non-cancellable term of the lease, which includes the effects of periodic step-ups in rent and rent abatements under the leases. We commence rental revenue recognition when the tenant takes possession of the leased space or controls the physical use of the leased space and the leased space is substantially ready for its intended use. In circumstances where we provide a tenant improvement allowance for improvements that are owned by the tenant, we recognize the allowance as a reduction of property rentals revenue on a straight-line basis over the term of the lease. Differences between rental income recognized and amounts due under the respective lease agreements are recorded as an increase or decrease to “Deferred rent receivable, net” on our balance sheets. Property rentals also includes the amortization of acquired above-and below-market leases, net.

Tenant reimbursements provide for the recovery of all or a portion of the operating expenses and real estate taxes of the respective assets. Tenant reimbursements are accrued in the same periods as the related expenses are incurred.

Third-party real estate services revenue, including reimbursements, is determined in accordance with the terms specific to each arrangement and may include property and asset management fees or transactional fees for leasing, acquisition, development and construction, financing, and legal services provided. These fees are determined in accordance with the terms specific to each arrangement and are recognized as the related services are performed. Development and construction fees earned from providing services to our unconsolidated real estate joint ventures are recorded on a percentage of completion basis.

Third-Party Real Estate Services Expenses

Third-party real estate services expenses include the costs associated with the management services provided to our unconsolidated real estate joint ventures and other third parties. We allocate personnel and other overhead costs using the estimates of the time spent performing services for our third-party business and other allocation methodologies.

Income Taxes

We intend to elect to be taxed as a REIT under sections 856-860 of the Internal Revenue Code of 1986, as amended (the "Code"), commencing with the filing of our tax return for the 2017 calendar year, effective for our tax year ending December 31, 2017. Under those sections, a REIT which distributes at least 90% of its REIT taxable income as dividends to its shareholders each year and which meets certain other conditions will not be taxed on that portion of its taxable income which is distributed to its shareholders. Prior to the Separation, the Vornado Included Assets historically operated under Vornado’s REIT structure. Since Vornado operates as a REIT and distributes 100% of taxable income to its shareholders, no provision for federal income taxes has been made in the accompanying financial statements for the periods prior to the Separation. We intend to continue to adhere to these requirements and maintain our REIT status in future periods.

As a REIT, we are allowed to reduce taxable income by all or a portion of our distributions to shareholders. Future distributions will be declared and paid at the discretion of the Board of Trustees and will depend upon cash generated by operating activities, our financial condition, capital requirements, annual dividend requirements under the REIT provisions of the Code, as amended, and such other factors as our Board of Trustees deems relevant.

13

We also participate in certain activities conducted by entities which elected to be treated as taxable REIT subsidiaries ("TRS") under the Code. As such, we are subject to federal, state, and local taxes on the income from these activities. Income taxes attributable to our TRSs are accounted for under the asset and liability method. Under the asset and liability method, deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future.

ASC 740-10, Income Taxes, provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. ASC 740-10 requires the evaluation of tax positions taken in the course of preparing our tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold are recorded as a tax expense in the current year. As of September 30, 2017, and December 31, 2016, we determined that no liabilities are required in connection with uncertain tax positions.

(Loss) Earnings Per Share

Basic (loss) earnings per common share ("EPS") is computed by dividing net (loss) income attributable to common shareholders by the weighted average common shares outstanding during the period. Unvested and vested share-based payment awards that entitle holders to receive non-forfeitable dividends, which include OP Units, long-term incentive partnership units ("LTIP Units") and out-performance award units ("OPP Units"), are considered participating securities. Consequently, we are required to apply the two-class method of computing basic and diluted earnings that would otherwise have been available to common shareholders. Under the two-class method, earnings for the period are allocated between common shareholders and participating securities based on their respective rights to receive dividends. During periods of net loss, losses are allocated only to the extent the participating securities are required to absorb their share of such losses. Diluted earnings per common share reflects the potential dilution of the assumed exchange of various units into common shares unvested share-based payment awards to the extent they are dilutive.

Share-Based Compensation

We granted OP Units, formation awards ("Formation Awards"), LTIP Units and OPP Units to our trustees, management and employees in connection with the Separation and Combination. The term and vesting of each award were determined by the compensation committee of our Board of Trustees (the “Compensation Committee”).

Fair value is determined, depending on the type of award, using the Monte Carlo method or post-vesting restriction periods, which is intended to estimate the fair value of the awards at the grant date using dividend yields and expected volatilities that are primarily based on available implied data and peer group companies' historical data. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The shortcut method is used for determining the expected life used in the valuation method.

Compensation expense for the Formation Awards, LTIP Units, OPP Units and certain OP Units is based on the fair value of our common shares at the date of the grant and is recognized ratably over the vesting period. For grants with a graded vesting schedule that are only subject to service conditions, we have elected to recognize compensation expense on a straight-line basis.

We also elected to account for forfeitures as they occur, rather than estimate expected forfeitures. Distributions paid on unvested OP Units, LTIPs and OPPs are charged to “net income attributable to noncontrolling interests” in the statements of operations.

Recent Accounting Pronouncements

The following table provides a brief description of recent accounting pronouncements (Accounting Standards Update or "ASU") by the FASB that could have a material effect on our financial statements:

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
Standard adopted
ASU 2017‑01 Business Combinations (Topic 805): Clarifying the Definition of a Business	This standard provides a screen to determine when an asset acquired or group of assets acquired is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated.	September 2017	The adoption and implementation of this standard did not have an impact on our results of operations, financial condition or cash flows.

14

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
Standards not yet adopted
ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities	The standard provides new guidance for the determination of eligibility for hedge accounting and effectiveness. It also amends the presentation and disclosure requirements. ASU 2017-12 requires a modified retrospective transition method which requires the recognition of the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption.	January 2019	We are currently evaluating the overall impact of the adoption of ASU 2017-12. The adoption of this standard is not expected to have a material impact on our financial statements.
ASU 2017‑09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting	This standard clarifies which changes to the terms or conditions of a share-based payment award are subject to the guidance on modification accounting under ASC Topic 718. Entities would apply the modification accounting guidance unless the value, vesting requirements and classification of a share-based payment award are the same immediately before and after a change to the terms or conditions of the award.	January 2018	We are currently evaluating the overall impact of the adoption of ASU 2017-09. The adoption of this standard is not expected to have a material impact on our financial statements.
ASU 2017‑05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets	This standard clarifies the scope of recently established guidance on nonfinancial asset derecognition as well as the accounting for partial sales of nonfinancial assets. This update conforms the derecognition guidance on nonfinancial assets with the model for transactions in ASC 606.	January 2018	The adoption of this standard is not expected to have a material impact on our financial statements.
ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments and ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash	These standards amend the existing guidance and address specific cash flow issues with the objective of reducing existing diversity in practice. ASU 2016-15 addresses eight specific cash flow issues and ASU 2016-18 specifically addresses presentation of restricted cash and restricted cash equivalents in the statements of cash flows. These standards require a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, entities may apply the amendments prospectively as of the earliest date practicable.	January 2018	Other than the revised statement of cash flows presentation of restricted cash, the adoption of these standards is not expected to have a material impact on our financial statements.

15

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
ASU 2016-02, Leases (Topic 842)	This standard sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. ASU 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase. Lessees are required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. Lessees will recognize expense based on the effective interest method for finance leases or on a straight-line basis for operating leases.	January 2019	We are currently evaluating the overall impact of the adoption of ASU 2016-02 on our financial statements, including the timing of adopting this standard. ASU 2016-02 will more significantly impact the accounting for leases in which we are the lessee. We have ground leases for which we will be required to record a right-of-use asset and lease liability equal to the present value of the remaining minimum lease payments upon adoption of this standard. We also expect that this standard will have an impact on the presentation of certain lease and non‑lease components of revenue from leases with no material impact to total revenue. Under ASU 2016-02, initial direct costs for both lessees and lessors would include only those costs that are incremental to the arrangement and would not have been incurred if the lease had not been obtained. As a result, we may no longer be able to capitalize internal leasing costs and instead may be required to expense these costs as incurred.
ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as clarified and amended by ASU 2016-08, ASU 2016-10 and ASU 2016-12	This standard establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. It requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and also requires certain additional disclosures. This standard may be adopted either retrospectively or on a modified retrospective basis.	January 2018	We currently expect to utilize the modified retrospective method of adoption. We have commenced the execution of our project plan for adopting this standard, which consists of gathering and evaluating the inventory of our revenue streams. We expect this standard will have an impact on the presentation of certain lease and non-lease components of revenue from leases upon the adoption of ASU 2016‑02, Leases, with no material impact on total revenues. We expect this standard will have an impact on the timing of gains on certain sales of real estate. We are continuing to evaluate the impact of this standard on our financial statements.

3. The Combination

On July 18, 2017, we completed the Combination and acquired the JBG Assets in exchange for approximately 37.2 million common shares and OP Units. The Combination has been accounted for at fair value under the acquisition method of accounting. The following allocation of the purchase price is based on preliminary estimates and assumptions and is subject to change based on a final determination of the assets acquired and liabilities assumed (in thousands):

16

Fair value of purchase consideration:
Common shares and OP Units	$	1,224,886
Cash	20,573
Total consideration paid	$	1,245,459
Fair value of assets acquired and liabilities assumed:
Land and improvements	$	342,932
Building and improvements	623,889
Construction in progress, including land	632,664
Leasehold improvements and equipment	7,890
Cash	104,516
Restricted cash	13,460
Investments in and advances to unconsolidated real estate ventures	238,388
Identified intangible assets	146,600
Notes receivable (1)	50,934
Identified intangible liabilities	(8,449		)
Mortgages payable assumed (2)	(768,523		)
Capital lease obligations assumed (3)	(33,543		)
Deferred tax liability (4)	(21,476		)
Other liabilities acquired, net	(52,065		)
Noncontrolling interests in consolidated subsidiaries	(3,987		)
Net assets acquired	1,273,230
Gain on bargain purchase (5)	27,771
Total consideration paid	$	1,245,459

____________________

⁽¹⁾  During the three months ended September 30, 2017, we received proceeds of $50.9 million from the repayment of the notes receivable acquired as part of the Combination.

⁽²⁾  Subject to various interest rate swap and cap agreements assumed in the Combination that are considered economic hedges, but not designated as accounting hedges.

⁽³⁾  As part of the Combination, two ground leases were assumed that were capital leases. On July 25, 2017, we purchased a land parcel located in Reston, Virginia associated with one of the ground leases for $19.5 million.

⁽⁴⁾  Related to the management and leasing contracts acquired in the Combination.

⁽⁵⁾  The Combination resulted in a gain on bargain purchase because the estimated fair value of the identifiable net assets acquired exceeded the purchase consideration by $27.8 million. The purchase consideration was based on the fair value of the common shares and OP Units issued in the Combination. We continue to reassess the recognition and measurement of identifiable assets and liabilities acquired and have preliminarily concluded that all acquired assets and liabilities were recognized and that the valuation procedures and resulting estimates of fair values were appropriate. 

The fair value of the common shares and OP Units purchase consideration was determined as follows (in thousands, except exchange ratio and price per share/unit):

Outstanding common shares and common limited partnership units prior to the Combination	100,571
Exchange ratio (1)	2.71

⁽³⁾  OP Unit consideration paid to certain of the owners of the JBG Assets which have an estimated fair value of $110.6 million is subject to post-combination employment with vesting over periods of either 12 or 60 months. In accordance with GAAP, consideration that is subject to future employment is not considered a component of the purchase price for the business combination and amortization is recognized as compensation expense over the period of employment and is included in "General and administrative expense: share-based compensation related to Formation Transaction" in the statements of operations.

The JBG Assets acquired comprise: (i) 30 operating assets comprising 19 office assets totaling approximately 3.6 million square feet (2.3 million square feet at our share), nine multifamily assets with 2,883 units (1,099 units at our share) and two other assets totaling approximately 490,000 square feet (73,000 square feet at our share); (ii) 11 office and multifamily assets under construction totaling over 2.5 million square feet (2.2 million square feet at our share); (iii) two near-term development office and multifamily assets totaling approximately 401,000 square feet (242,000 square feet at our share); (iv) 26 future development assets totaling approximately 11.7 million square feet (8.5 million square feet at our share) of estimated potential development density; and (v) JBG/Operating Partners, L.P., a real estate services company providing investment, development, asset management, property management, leasing, construction management and other services. JBG/Operating Partners, L.P. was owned by 20 unrelated individuals of which 19 became our employees, and three serve on our Board of Trustees.

6.    Variable Interest Entities

Unconsolidated VIEs

As of September 30, 2017 and December 31, 2016, we have interests in several investments that are deemed VIEs that are in development stage and do not hold sufficient equity at risk or conduct substantially all their operations on behalf of the investor with disproportionately few voting rights. Although we are engaged to act as the managing partner in charge of day-to-day operations of these investees, we are not the primary beneficiary of these VIEs as we do not hold unilateral power over activities that, when taken together, most significantly impact the respective VIE’s performance. We account for our investment in these entities under the equity method. As of September 30, 2017 and December 31, 2016, the net carrying amounts of our investment in these entities were $203.0 million and $42.4 million, respectively. Our maximum exposure to loss in these entities is limited to our investments, construction commitments and debt guarantees. See Note 16 for additional information.

Consolidated VIEs

JBG SMITH LP, our operating partnership, is our most significant consolidated VIE. We hold the majority membership interest in the operating partnership, act as the general partner and exercise full responsibility, discretion and control over its day-to-day management.

The noncontrolling interests of the operating partnership do not have either substantive liquidation rights, or substantive kick-out rights without cause, or substantive participating rights that could be exercised by a simple majority of noncontrolling interest members (including by such a member unilaterally). Because the noncontrolling interest holders do not have these rights, the operating partnership is a VIE. As general partner, we have the power to direct the core activities of the operating partnership that most significantly affect its performance, and through our majority interest in the operating partnership have both the right to receive benefits from and the obligation to absorb losses of the operating partnership. Accordingly, we are the primary beneficiary of the operating partnership and consolidate the operating partnership in our financial statements. As we conduct our business and hold our assets and liabilities through the operating partnership, the total assets and liabilities of the operating partnership comprise substantially all of our consolidated assets and liabilities.

We also consolidate certain VIEs that have minimal noncontrolling interests (less than 5%). These entities are VIEs because the noncontrolling interests do not have substantive kick-out or participating rights. We consolidate these entities because we control all of their significant business activities. As of September 30, 2017, the total assets and liabilities of such consolidated VIEs, excluding the operating partnership, were approximately $78.8 million and $5.1 million, respectively.

⁽³⁾  Includes mortgages payable assumed as part of the Combination. See Note 3 to the financial statements for additional information.

⁽⁴⁾  In June 2016, the mortgage loan for the Bowen Building was repaid with proceeds of a $115.6 million draw on our former parent's revolving credit facility collateralized by an interest in the property, and, accordingly, was reflected as a component of "Payable to former parent" on the combined balance sheets as of December 31, 2016. We repaid the loan with amounts drawn under our revolving credit facility collateralized by a mortgage on the property.

As of September 30, 2017, the net carrying value of real estate collateralizing our mortgages payable totaled $3.9 billion. Our mortgage loans contain covenants that limit our ability to incur additional indebtedness on these properties and in certain circumstances, require lender approval of tenant leases and/or yield maintenance upon repayment prior to maturity. As of September 30, 2017, we were in compliance with all debt covenants.

As part of the Combination, we assumed mortgages payable with an aggregate principal balance of $768.5 million. During the three months ended September 30, 2017, we repaid mortgages payable with an aggregate principal balance of $181.7 million, which includes mortgages payable totaling $63.7 million assumed in the Combination. We recognized losses on extinguishment of debt in conjunction with these repayments of $689,000 for the three and nine months ended September 30, 2017.

Credit Facility

On July 18, 2017, we entered into a $1.4 billion credit facility, consisting of a $1.0 billion revolving credit facility maturing in July 2021, with twosix-month extension options, a delayed draw $200.0 million unsecured term loan ("Tranche A-1 Term Loan") maturing in January 2023 and a delayed draw $200.0 million unsecured term loan ("Tranche A-2 Term Loan") maturing in July 2024. The interest rate for the credit facility varies based on a ratio of our total outstanding indebtedness to a valuation of certain real property and assets and ranges (a) in the case of the revolving credit facility, from LIBOR plus 1.10% to LIBOR plus 1.50%, (b) in the case of the Tranche A-1 Term Loan, from LIBOR plus 1.20% to LIBOR plus 1.70% and (c) in the case of the Tranche A-2 Term Loan, from LIBOR plus 1.55% to LIBOR plus 2.35%.

On July 18, 2017, in connection with the Combination, we drew $115.8 million on the revolving credit facility and $50.0 million under the Tranche A-1 Term Loan. In connection with the execution of the credit facility, we incurred $11.2 million in fees and expenses.

The following is a summary of amounts outstanding under the credit facility as of September 30, 2017:

10.    Redeemable Noncontrolling Interests

In conjunction with the Formation Transaction, JBG SMITH LP issued 19.8 million OP Units to persons other than JBG SMITH that are redeemable for cash or our common shares beginning August 1, 2018, subject to certain limitations. These OP Units represent a 14.4% interest in JBG SMITH LP as of September 30, 2017. The carrying amount of the redeemable noncontrolling interests is adjusted to its redemption value at the end of each reporting period, but no less than its initial carrying value, with such adjustments recognized in "Additional paid-in capital". Redemption value is equivalent to the market value of one of our common

25

shares at the end of the period multiplied by the number of vested OP Units outstanding. Below is a summary of the activity of redeemable noncontrolling interests for the nine months ended September 30, 2017:

__________________

⁽¹⁾  We did not have any redeemable noncontrolling interests prior to the Separation on July 17, 2017.

⁽²⁾  Excludes certain OP Units issued as part of the Combination which have an estimated fair value of $110.6 million, that are subject to post-combination employment with vesting over periods of either 12 or 60 months. See Note 11 for further information.

11.     Share-Based Payments and Employee Benefits

OP UNITS

Certain OP Units issued as part of the Combination which have an estimated fair value of $110.6 million, are subject to post-combination employment with vesting over periods of either 12 or 60 months. The fair value of these 3.3 million OP Units was estimated based on the post-vesting restriction periods of the units. The significant assumptions used to value the units include expected volatilities (18.0% to 27.0% ), risk-free interest rates (1.3% to 1.5%) and post-vesting restriction periods (1 year to 3 years). Compensation expense for these units is recognized over the graded vesting period. See Note 3 for additional information. As of September 30, 2017, none of these OP Units had vested or been forfeited.

JBG SMITH 2017 Omnibus Share Plan

On June 23, 2017, our Board of Trustees adopted the JBG SMITH 2017 Omnibus Share Plan (the "Plan"), effective as of July 17, 2017, and authorized the reservation of approximately 10.3 million of our common shares pursuant to the Plan. On July 10, 2017, our then sole-shareholder approved the Plan. As of September 30, 2017, there were 6.6 million common shares available for issuance under the Plan.

Formation Awards

Pursuant to the Plan, on July 18, 2017, we granted approximately 2.7 million Formation Awards based on an aggregate notional value of approximately $100.0 million divided by the volume-weighted average price on July 18, 2017 of $37.10 per common share. The Formation Awards are structured in the form of profits interests in JBG SMITH LP that provide for a share of appreciation determined by the increase in the value of a common share at the time of conversion over the $37.10 volume-weighted average price of a common share at the time the formation unit was granted. The Formation Awards, subject to certain conditions, generally vest 25% on each of the third and fourth anniversaries and 50% on the fifth anniversary, of the closing of the Combination, subject to continued employment with JBG SMITH through each vesting date.

The value of vested Formation Awards is realized through conversion into a number of LTIP Units, and subsequent conversion into a number of OP Units determined based on the difference between $37.10 and the value of a common share on the conversion date. The conversion ratio between Formation Awards and OP Units, which starts at zero, is the quotient of (i) the excess of the value of a common share on the conversion date above the per share value at the time the Formation Award was granted over (ii) the value of a common share as of the date of conversion. This is similar to a “cashless exercise” of stock options, whereby the holder receives a number of shares equal in value to the difference between the full value of the total number of shares for which the option is being exercised and the total exercise price. Like options, Formation Awards have a finite term over which their value is allowed to increase and during which they may be converted into LTIP Units (and in turn, OP Units). Holders of Formation Awards will not receive distributions or allocations of net income or net loss prior to vesting and conversion to LTIP Units.

The fair value of the Formation Awards on the grant date was $23.7 million or $8.84 per unit estimated using Monte Carlo simulations. The significant assumptions used to value the awards include expected volatility (26.0%), dividend yield (2.3%), risk-free interest rate (2.3%) and expected life (7 years). Compensation expense for these awards is being recognized over a five-year period. As of September 30, 2017, none of these Formation Awards had vested or been forfeited.

LTIP Units

On July 18, 2017, we granted a total of 47,166 fully vested LTIP Units to the seven non-employee trustees in the notional amount of $250,000 each. The LTIP Units may not be sold while such non-employee trustee is serving on the Board. On the same date, we also granted 59,927 LTIP units to a key employee 50%, which vested immediately and 50% of which vests in equal monthly installments from the 31st to 60th months following the grant date. These LTIP Units had an aggregate fair value of $3.5 million.

On August 1, 2017, we granted approximately 302,500 LTIP Units to management and other employees under our Plan. The LTIP units vest in four equal installments on August 1 of each year, subject to continued employment. These LTIP Units were valued at a weighted average grant-fair value of $33.71 per unit. Compensation expense for these units is being recognized over a four-year period. As of September 30, 2017, none of these LTIP Units had vested or been forfeited.

The fair value of the LTIP Units was estimated based on the post-vesting restriction periods. The significant assumptions used to value the units include expected volatilities (17.0% to 19.0%), risk-free interest rates (1.3% to 1.5%) and post-vesting restriction periods (2 years to 3 years). Net income and net loss is allocated to each LTIP Unit. LTIP Unit holders have the right to convert all or a portion of vested LTIP Units into OP Units, which are then subsequently exchangeable for our common shares. LTIP Units do not have redemption rights, but any OP Units into which LTIP Units are converted are entitled to redemption rights. LTIP Units, generally, vote with the OP Units and do not have any separate voting rights except in connection with actions that would materially and adversely affect the rights of the LTIP Units.

OPP Units

On August 1, 2017, we granted approximately 605,100 OPP Units to management and other employees under the Plan. OPP Units are performance-based equity compensation pursuant to which participants have the opportunity to earn OPP units based on the relative performance of the total shareholder return ("TSR") of our common shares compared to the companies in the FTSE NAREIT Equity Office Index, over the three-year performance period beginning on the August 1, 2017 grant date, inclusive of dividends and stock price appreciation. Fifty percent of any OPP Units that are earned vest at the end of the three-year performance period and the remaining 50% on the fourth anniversary of the date of grant, subject to continued employment. Net income and net loss are allocated to each OPP Unit. The fair value of the OPP Units on the date of grant was $9.7 million or $15.95 per unit estimated using Monte Carlo simulations. The significant assumptions used to value the OPP Units include expected volatility (18.0%), dividend yield (2.3%) and risk-free interest rates (1.5%). Compensation expense for these units is being recognized over a four-year period. As of September 30, 2017, none of these OPP Units had vested or been forfeited.

⁽⁴⁾  Net share-based compensation expense for the three months ended September 30, 2017 was $16.0 million.

As of September 30, 2017, we had $141.4 million of total unrecognized compensation expense related to unvested share-based payment arrangements (unvested OP Units, Formation Awards, LTIP Units and OPP Units). This expense is expected to be recognized over a weighted average period of 3.4 years.

Employee Benefits

We have a 401(k) defined contribution plan (the “401(k) Plan”) covering substantially all of our officers and employees which permits participants to defer compensation up to the maximum amount permitted by law. We provide a discretionary matching contribution. Employees’ contributions vest immediately and our matching contributions vest over five years. Our contributions to the 401(k) Plan for three months ended September 30, 2017 and 2016 were $401,000 and $868,000, respectively. Our contributions during the nine months endedSeptember 30, 2017 and 2016 were $3.2 million and $3.1 million, respectively.

12.     (Loss) Earnings Per Share

The following summarizes the calculation of basic and diluted EPS and provides a reconciliation of the amounts of net (loss) income available to common shareholders and shares of common stock used in calculating basic and diluted EPS for the three and nine months ended September 30, 2017 and 2016:

	Three Months Ended September 30,					Nine Months Ended September 30,
	2017			2016		2017			2016
	(In thousands, except per share amounts)
Net (loss) income attributable to JBG SMITH Properties	$	(69,831	)	$	21,014	$	(57,851	)	$	49,344
Weighted average shares outstanding — basic and diluted (1)	114,744			100,571		105,347			100,571
(Loss) earnings per share available to common shareholders:
Basic	$	(0.61	)	$	0.21	$	(0.55	)	$	0.49
Diluted	$	(0.61	)	$	0.21	$	(0.55	)	$	0.49

_______________

⁽¹⁾  Reflects the weighted average common shares outstanding as of the date of the Separation in all periods prior to July 17, 2017.

The effect of the conversion of 13,408 and 4,518 weighted average vested OP Units for the three and nine months ended September 30, 2017 is excluded in the computation of basic and diluted loss per share, as the assumed exchange of such units for common shares on a one-for-one basis was antidilutive (the assumed conversion of these units would have no net impact on the determination of diluted earnings per share). As vested and outstanding OP Units are held by a noncontrolling interest, losses are attributable to them based on the weighted average outstanding units and are thus excluded from the numerator in calculating basic and diluted loss per share. The number of securities that were excluded from the calculation of diluted (loss) earnings per share because they were antidilutive that potentially could be dilutive in the future are included in the following table:

	Three Months Ended September 30,		Nine Months Ended September 30,
	2017	2016	2017	2016
OP Units	3,281	—	3,281	—
Formation Awards	2,681	—	2,681	—
LTIP Units	410	—	410	—
OPP Units	605	—	605	—

13.     Future Minimum Rental Income

28

We lease space to tenants under operating leases that expire at various dates through the year 2036. The leases provide for the payment of fixed base rents payable monthly in advance as well as reimbursements of real estate taxes, insurance and maintenance costs. Retail leases may also provide for the payment by the lessee of additional rents based on a percentage of their sales. As of September 30, 2017, future base rental revenue under these non-cancelable operating leases excluding extension options is as follows:

Year ending December 31,	Amount
	(In thousands)
2017	$	133,025
2018	387,636
2019	310,230
2020	277,278
2021	234,005
2022	195,750
Thereafter	868,284

14.    Fair Value Measurements

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

As of September 30, 2017, we had various interest rate swap and cap agreements assumed in the Combination that are measured at fair value on a recurring basis. There were no interest rate swaps or caps prior to the Combination. The net unrealized gain on our interest rate swaps and caps was $467,000 for both the three and nine months ended September 30, 2017 and are included in "Interest expense" in the accompanying statements of operations. The fair values of the interest rate swaps and caps are based on the estimated amounts we would receive or pay to terminate the contract at the reporting date and are determined using interest rate pricing models and observable inputs. The interest rate swaps and caps are classified within Level 2 of the valuation hierarchy.

The following are liabilities measured at fair value on a recurring basis as of September 30, 2017:

Financial Assets and Liabilities Not Measured at Fair Value

As of September 30, 2017 and December 31, 2016, all financial instruments and liabilities were reflected in our balance sheets at amounts which, in our estimation, reasonably approximated their fair values, except for the following:

	September 30, 2017				December 31, 2016
	Carrying       Amount (1)		Fair Value		Carrying       Amount (1)		Fair Value
	(In thousands)
Financial liabilities:
Mortgages payable	$	1,988,247	$	2,015,653	$	1,167,618	$	1,192,267

^{______________________________________} 

⁽¹⁾ The carrying amount consists of principal only.

29

The fair value of our mortgages payable is estimated by discounting the future contractual cash flows of these instruments using current risk-adjusted rates available to borrowers with similar credit ratings, which are provided by a third-party specialist. The fair value of the mortgages payable and unsecured term loan was determined using Level 2 inputs of the fair value hierarchy.

The fair value of our unsecured term loan is calculated based on the net present value of payments over the term of the loan using estimated market rates for similar notes and remaining terms. The fair value of the unsecured term loan was determined using Level 2 inputs of the fair value hierarchy.

15.    Segment Information

We review operating and financial data for each property on an individual basis; therefore, each of our individual properties is a separate operating segment. As a result of the Formation Transaction, we redefined our reportable segments to be aligned with our method of internal reporting and the way our Chief Executive Officer, who is also our Chief Operating Decision Maker (“CODM”), makes key operating decisions, evaluates financial results, allocates resources and manages our business. Accordingly, we aggregate our operating segments into three reportable segments (office, multifamily, and third-party real estate services) based on the economic characteristics and nature of our assets and services. In connection therewith, we have reclassified the prior period segment financial data to conform to the current period presentation.

The CODM measures and evaluates the performance of our operating segments, with the exception of the third-party real estate services business, based on the net operating income (“NOI”) of properties within each segment. NOI includes property rental revenues and tenant reimbursements and deducts property operating expenses and real estate taxes.

With respect to the third-party real estate services business, the CODM reviews revenues streams generated by this segment (third-party real estate services, including reimbursements), as well as the expenses attributable to the segment (general and administrative: third-party real estate services), which are disclosed separately in the statements of operations. Management company assets primarily consist of management and leasing contracts with a net book value of $56.0 million classified in "Other assets, net" in the balance sheet as of September 30, 2017. Consistent with the CODM approach and our definition of NOI, the third-party real estate services operating results are excluded from the NOI data below.

The following table reflects the reconciliation of net (loss) income attributable to JBG SMITH Properties to NOI for the three and nine months ended September 30, 2017 and 2016:

16.    Commitments and Contingencies

Insurance

We maintain general liability insurance with limits of $200.0 million per occurrence and in the aggregate, and property and rental value insurance coverage with limits of $2.0 billion per occurrence, with sub-limits for certain perils such as floods and earthquakes on each of our properties. We also maintain coverage for terrorist acts with limits of $2.0 billion per occurrence and in the aggregate, and $2.0 billion per occurrence and in the aggregate for nuclear, biological, chemical and radiological terrorism events, as defined by the Terrorism Risk Insurance Program Reauthorization Act, which expires in December 2020. Insurance premiums are charged directly to each of the properties and are included in "Property operating expenses" in the statement of operations.

We will continue to monitor the state of the insurance market and the scope and costs of coverage for acts of terrorism. We cannot anticipate what coverage will be available on commercially reasonable terms in the future. We are responsible for deductibles and losses in excess of the insurance coverage, which could be material.

Our debt, consisting of mortgage loans secured by our properties, revolving credit facility and unsecured term loans contain customary covenants requiring adequate insurance coverage. Although we believe that we currently have adequate insurance coverage, we may not be able to obtain an equivalent amount of coverage at reasonable costs in the future. If lenders insist on greater coverage than we are able to obtain, it could adversely affect the ability to finance or refinance our properties.

Construction Commitments

As of September 30, 2017, we have construction in progress that will require an additional $707.8 million to complete ($611.1 million related to our consolidated entities and $96.7 million related to our unconsolidated real estate ventures at our share), based on our current plans and estimates, which we anticipate will be primarily expended over the next two to three years. These capital expenditures are generally due as the work is performed, and we expect to finance them with debt proceeds, proceeds from asset recapitalizations and sales, and available cash.

32

Environmental Matters

Each of our properties has been subjected to varying degrees of environmental assessment at various times. The environmental assessments did not reveal any material environmental contamination that we believe would have a material adverse effect on our overall business, financial condition or results of operations. Nevertheless, there can be no assurance that the identification of new areas of contamination, changes in the extent or known scope of contamination, the discovery of additional sites or changes in cleanup requirements would not result in significant cost to us.

Other

There are various legal actions against us in the ordinary course of business. In our opinion, the outcome of such matters will not have a material adverse effect on our financial condition, results of operations or cash flows.

From time to time, we (or ventures in which we have an ownership interest) have agreed, and may in the future agree, to (1) guarantee portions of the principal, interest and other amounts in connection with their borrowings, (2) provide customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) in connection with their borrowings and (3) provide guarantees to lenders and other third parties for the completion of development projects. We customarily have agreements with our outside partners whereby the partners agree to reimburse the joint venture or us for their share of any payments made under the guarantee. Amounts that may be required to be paid in future periods in relation to budget overruns or operating losses that also included in some of our guarantees are not estimable. Guarantees (excluding environmental) terminate either upon the satisfaction of specified circumstances or repayment of the underlying debt. As of September 30, 2017, the aggregate amount of our principal payment guarantees was approximately $89.0 million for our consolidated entities and $63.8 million for our unconsolidated real estate ventures.

As of September 30, 2017, we expect to fund additional capital to certain of our unconsolidated investments totaling approximately $50.6 million, , which we anticipate will be primarily expended over the next two to three years.

We are obligated under non-cancelable operating leases, primarily for ground leases on certain of our properties through 2112. As of September 30, 2017, future minimum rental payments under non-cancelable operating and capital leases are as follows:

Year ending December 31,	Amount
	(In thousands)
2017	$	1,974
2018	8,391
2019	8,170
2020	7,825

17. Transactions With Vornado and JBG Legacy Funds

Transactions with Vornado

As described in Note 1 and Note 3, the accompanying financial statements present the operations of the office and multifamily assets as carved-out from the financial statements of Vornado for all periods prior to July 17, 2017.

Certain centralized corporate costs borne by Vornado for management and other services including, but not limited to, accounting, reporting, legal, tax, information technology and human resources have been allocated to the assets in the consolidated and combined financial statements based on either actual costs incurred or a proportion of costs estimated to be applicable to the Vornado Included Assets based on key metrics including total revenue. The total amounts allocated during the three months ended September 30, 2017 and 2016 were $873,000 and $4.5 million, respectively. The total amounts allocated during the nine months endedSeptember 30, 2017 and 2016 were $13.0 million and $15.2 million, respectively. These allocated amounts are included as a component of "General and administrative expense: corporate and other" expenses on the statements of operations and do not necessarily reflect what actual costs would have been if the Vornado Included Assets were a separate standalone public company.

33

Actual costs may be materially different. Allocated amounts for the three and nine months ended September 30, 2017 and 2016 are not necessarily indicative of allocated amounts for a full year.

In connection with the Formation Transaction, we entered into an agreement with Vornado under which Vornado provides operational support for an initial period of up to two years. These services include information technology, financial reporting and payroll services. The charges for these services are based on an hourly or per transaction fee arrangement including reimbursement for overhead and out-of-pocket expenses. The total charges for both the three months and nine months endedSeptember 30, 2017 were approximately $912,000. Pursuant to an agreement, we are providing Vornado with leasing and property management services for certain of its assets that were not part of the Separation. The total revenue related to these services for both the three months and nine months endedSeptember 30, 2017 was $68,000. We believe that the terms of both of these agreements are comparable to those that would have been negotiated based on market rates.

In August 2014, we completed a $185.0 million financing of the Universal buildings, a 687,000 square foot office complex located in Washington, DC. In connection with this financing, pursuant to a note agreement dated August 12, 2014, we used a portion of the financing proceeds and made an $86.0 million loan to Vornado at LIBOR plus 2.9% due August 2019. During 2016 and 2015, Vornado repaid $4.0 million and $7.0 million of the loan receivable, respectively. At the Separation, Vornado repaid the outstanding balance of the loan and related accrued interest. As of December 31, 2016, the balance of the receivable from Vornado, including accrued interest, was $75.1 million. We recognized interest income of $130,000 and $1.8 million during the three and nine months ended September 30, 2017, respectively, and $830,000 and $2.3 million during the three and nine months ended September 30, 2016, respectively.

In connection with the development of The Bartlett, prior to the Combination, we entered into various note agreements with Vornado whereby we could borrow up to a maximum of $170.0 million. Vornado contributed these note agreements along with accrued and unpaid interest to JBG SMITH at the Separation. As of December 31, 2016, the amounts outstanding under these note agreements at were $166.5 million, and are included in "Payable to former parent" on our balance sheets. We incurred interest of $365,000 and $4.1 million during the three and nine months ended September 30, 2017, respectively, and $1.2 million and $3.0 million during the three and nine months ended September 30, 2016, respectively.

In June 2016, the $115.0 million mortgage loan (including $608,000 of accrued interest) secured by the Bowen Building, a 231,000 square foot office building located in Washington, DC, was repaid with the proceeds of a $115.6 million draw on Vornado’s revolving credit facility. The loan was repaid with amounts drawn under our revolving credit facility. See Note 8 for further information. Given that the $115.6 million draw on Vornado’s credit facility is secured by an interest in the property, such amount was included in "Payable to former parent" in our balance sheets as of December 31, 2016. We incurred interest expense of $120,000 and $1.3 million during the three and nine months ended September 30, 2017, respectively, and $457,000 and $602,000 for the three and nine months ended September 30, 2016, respectively.

We have agreements, that are terminable on the second anniversary of the Combination, with Building Maintenance Services ("BMS"), a wholly owned subsidiary of Vornado, to supervise cleaning, engineering and security services at our properties. We paid BMS $3.6 million and $9.9 million during the three and nine months ended September 30, 2017, respectively, and $3.3 million and $9.6 million during the three and nine months ended September 30, 2016, respectively, which are included in "Property operating expenses" in our statements of operations.

We entered into a consulting agreement with Mr. Schear, a member of our Board of Trustees and formerly the president of Vornado’s Washington, DC segment. The consulting agreement expires on December 31, 2017 and provides for the payment of consulting fees at the rate of $166,667 per month for the 24 months following the Separation, including after the termination of the consulting agreement. The amount due under this consulting agreement of $4.1 million was recorded as a liability in connection with the Combination. As of September 30, 2017, the remaining liability is $3.6 million. In March 2017, Vornado amended Mr. Schear’s employment agreement with Vornado to provide for the payments that Mr. Schear will receive in connection with certain post-employment services.

Fees from JBG Legacy Funds

In addition to our portfolio, we have a third-party real estate services business that provides fee-based real estate services to our real estate ventures, legacy funds formerly organized by JBG and other third parties. We provide services for the benefit of the JBG Legacy Funds that own interests in the assets retained by the JBG Legacy Funds. In connection with the contribution of the JBG Assets to us, it was determined that the general partner and managing member interests in the JBG Legacy Funds that were held by former JBG executives (and who became members of our management team and/or Board of Trustees) would not be transferred to us and remain under the control of these individuals. In addition, members of our senior management and Board of Trustees have an ownership interest in the JBG Legacy Funds and own carried interests in each fund and in certain of our joint ventures that entitles them to receive additional compensation if the fund or joint venture achieves certain return thresholds.  This third-party real estate services revenue, including reimbursements, from these JBG Legacy Funds for both the three and nine months ended September 30, 2017 was $8.4 million. 

34

Registration Rights Agreements

In connection with the Formation Transaction, we entered into a registration rights agreement with certain former investors in the legacy JBG funds that received our common shares in the Formation Transaction (the "Shares Registration Rights Agreement") and a separate registration rights agreement with the certain former investors in the legacy JBG funds and certain employees of JBG entities that received OP Units in the Formation Transaction (the "OP Units Registration Rights Agreement" and together with the Shares Registration Rights Agreement, the "Registration Rights Agreements"). Certain holders of common shares and OP Units who may benefit from the Registration Rights Agreements are members of our management team and/or Board of Trustees.

18. Subsequent Events

In October 2017, we closed a $78.0 million loan on 1235 South Clark, an office asset in Crystal City, Virginia.  The loan has a 10-year term and a fixed interest rate of 3.94%.

In October 2017, we repaid a $67.3 million loan at 220 20th Street, a multifamily asset located in Crystal City, Virginia.

In October 2017, we entered into agreements in the specified notional amounts to swap variable interest rates to fixed rates on the following debt instruments:

• $50.0 million related to our Tranche A-1 Term Loan;

• $107.7 million related to our mortgage loan on RTC - West; and

• $107.5 million related to our mortgage loan on 800 North Glebe Road.

In November 2017, we closed a $110.0 million refinancing on Atlantic Plumbing, a multifamily and retail asset in the U Street/Shaw submarket of Washington, DC.  The loan has a five-year term and a floating rate of LIBOR plus 1.50%. A prior swap agreement has been novated to synthetically fix the interest rate through September 2020. At closing, $100.0 million was funded, which was used in part to repay the existing $88.4 million loan. We have the ability to draw an additional $10.0 million based on the asset’s performance. 

On November 9, 2017, our Board of Trustees declared a quarterly dividend of $0.225 per common share, payable on November 30, 2017 to shareholders of record on November 20, 2017.

Organization and Basis of Presentation

JBG SMITH Properties ("JBG SMITH") was organized by Vornado Realty Trust ("Vornado" or "former parent") as a Maryland real estate investment trust ("REIT") on October 27, 2016 (capitalized on November 22, 2016). JBG SMITH was formed for the purpose of receiving, via the spin-off on July 17, 2017 (the "Separation"), substantially all of the assets and liabilities of Vornado’s Washington, DC segment, which operated as Vornado / Charles E. Smith, (the "Vornado Included Assets"). On July 18, 2017, JBG SMITH acquired the management business and certain assets and liabilities (the "JBG Assets") of The JBG Companies (the "Combination"). The Separation and the Combination are collectively referred to as the "Formation Transaction." Unless the context otherwise requires, all references to "we," "us," and "our," refer to the Vornado Included Assets, our predecessor and accounting acquirer, for periods prior to the Separation and to JBG SMITH for periods from and after the Separation and Combination.

Prior to the Separation from Vornado, JBG SMITH was a wholly owned subsidiary of Vornado and had no material assets or operations. Pursuant to a separation agreement, on July 17, 2017, Vornado distributed 100% of the then outstanding common shares of JBG SMITH on a pro rata basis to the holders of its common shares. Prior to such distribution by Vornado, Vornado Realty L.P. ("VRLP"), Vornado's operating partnership, distributed common limited partnership units ("OP Units") in JBG SMITH Properties LP ("JBG SMITH LP"), our operating partnership, on a pro rata basis to the holders of VRLP's common limited partnership units, consisting of Vornado and the other common limited partners of VRLP. Following such distribution by VRLP and prior to such distribution by Vornado, Vornado contributed to JBG SMITH all of the OP Units it received in exchange for common shares of JBG SMITH. Each Vornado common shareholder received one JBG SMITH common share for every two Vornado common shares held as of the close of business on July 7, 2017 (the "Record Date").  Vornado and each of the other limited partners of VRLP received one JBG SMITH LP OP Unit for every two common limited partnership units in VRLP held as of the close of business on the Record Date. The operations of JBG SMITH are presented as if the transfer of the Vornado Included Assets had been consummated prior to all historical periods presented in the accompanying financial statements at the carrying amounts of such assets and liabilities reflected in Vornado’s books and records.

The following is a discussion of the historical results of operations and liquidity and capital resources of JBG SMITH as of and for the three- and nine-month periods ended September 30, 2017 and 2016, which includes results prior to the consummation of the Formation Transaction. The historical results presented prior to the consummation of the Formation Transaction include the Vornado Included Assets, all of which were under common control of Vornado until July 17, 2017. Unless otherwise specified, the discussion of the historical results prior to July 18, 2017 does not include the results of the JBG Assets . The following discussion should be read in conjunction with the condensed consolidated and combined interim financial statements and notes thereto appearing in "Item 1. Financial Statements.".

References to the financial statements refer to our condensed consolidated and combined financial statements as of September 30, 2017 and December 31, 2016, and for the three and nine months ended September 30, 2017 and 2016. References to the balance sheets refer to our condensed consolidated and combined balance sheets as of September 30, 2017 and December 31, 2016. References to the statements of operations refer to our condensed consolidated and combined statements of operations for the three

36

and nine months ended September 30, 2017 and 2016. References to the statements of cash flows refer to our condensed consolidated and combined statements of cash flows for the nine months ended September 30, 2017 and 2016.

The accompanying unaudited financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, and revenue and expenses during the reporting periods. Actual results could differ from these estimates. The historical financial results for the Vornado Included Assets reflect charges for certain corporate costs allocated by the former parent which we believe are reasonable. These charges were based on either actual costs incurred or a proportion of costs estimated to be applicable to the Vornado Included Assets based on an analysis of key metrics, including total revenues. Such costs do not necessarily reflect what the actual costs would have been if the Vornado Included Assets had been operating as a separate standalone public company. These charges are discussed further in Note 17 to the financial statements.

We intend to elect to be taxed as a REIT under sections 856-860 of the Internal Revenue Code of 1986, as amended (the "Code"), commencing with the filing of our tax return for the 2017 calendar year, effective for our tax year ending December 31, 2017. Under those sections, a REIT which distributes at least 90% of its REIT taxable income as dividends to its shareholders each year and which meets certain other conditions will not be taxed on that portion of its taxable income which is distributed to its shareholders. Prior to the Separation, the Vornado Included Assets historically operated under Vornado’s REIT structure. Since Vornado operates as a REIT and distributes 100% of taxable income to its shareholders, no provision for federal income taxes has been made in the accompanying financial statements for the periods prior to the Separation. We intend to continue to adhere to these requirements and maintain our REIT status in future periods.

As a REIT, we are allowed to reduce taxable income by all or a portion of our distributions to shareholders. Future distributions will be declared and paid at the discretion of our Board of Trustees and will depend upon cash generated by operating activities, our financial condition, capital requirements, annual dividend requirements under the REIT provisions of the Code, as amended, and such other factors as our Board of Trustees deems relevant.

We also participate in certain activities conducted by entities which elected to be treated as taxable REIT subsidiaries ("TRS") under the Code. As such, we are subject to federal, state, and local taxes on the income from these activities. Income taxes attributable to our TRSs are accounted for under the asset and liability method. Under the asset and liability method, deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future.

We aggregate our operating segments into three reportable segments (office, multifamily, and third-party real estate services) based on the economic characteristics and nature of our assets and services.

We compete with a large number of property owners and developers. Our success depends upon, among other factors, trends affecting national and local economies, the financial condition and operating results of current and prospective tenants, the availability and cost of capital, interest rates, construction and renovation costs, taxes, governmental regulations and legislation, population trends, zoning laws, and our ability to lease, sublease or sell our assets at profitable levels. Our success is also subject to our ability to refinance existing debt on acceptable terms as it comes due.

Overview

We own and operate a portfolio of high-quality office and multifamily assets, many of which are amenitized with ancillary retail. Our portfolio reflects our longstanding strategy of concentrating in downtown Washington, DC and other leading urban-infill submarkets with proximity to downtown Washington, DC that have high barriers to entry and key urban amenities, including being within walking distance of a Metro station. 

As of September 30, 2017, our portfolio comprised: (i) 69 operating assets comprising 51 office assets totaling over 13.7 million square feet (11.8 million square feet at our share), 14 multifamily assets totaling 6,016 units (4,232 units at our share) and four other assets totaling approximately 765,000 square feet (348,000 square feet at our share); (ii) nine assets under construction comprising four office assets totaling approximately 1.3 million square feet (1.2 million square feet at our share), four multifamily assets totaling 1,334 units (1,149 units at our share) and one other asset totaling approximately 41,100 square feet (4,100 square feet at our share; (iii) one near-term development multifamily asset totaling 433 units (303 units at our share), and (iv) 42 future development assets totaling approximately 21.3 million square feet (17.6 million square feet at our share) of estimated potential development density.

Key highlights of operating results for the three months ended September 30, 2017 included:

▪ a net loss of $69.8 million, or $0.61 per diluted common share, for the three months ended September 30, 2017 as compared to net income of $21.0 million, or $0.21 per diluted common share, for the three months ended September 30, 2016. The net

37

loss for the three months ended September 30, 2017 was due in part to transaction and other costs of $104.1 million partially offset by a gain on bargain purchase of $27.8 million;

▪ an increase in operating office portfolio leased and occupied percentages to 88.2% leased and 87.5% occupied as of September 30, 2017 from 87.5% and 86.2% as of June 30, 2017;

▪ an increase in operating multifamily portfolio occupancy to 94.6% as of September 30, 2017 from 93.9% as of June 30, 2017. Multifamily portfolio leased percentage decreased to 96.2% as of September 30, 2017 from 96.8% as of June 30, 2017;

▪ the leasing of approximately 289,000 square feet, or 206,000 square feet at our share ⁽¹⁾, at an initial rent ⁽²⁾ of $43.08 per square foot; and

▪ an increase in same store ⁽³⁾ net operating income ("NOI") of 6.3% to $70.3 million for the three months ended September 30, 2017 as compared to $66.1 million for the three months ended September 30, 2016.

Additionally, investing and financing activity during the three months ended September 30, 2017 included:

▪ the issuance of 94.7 million common shares and 5.8 million OP Units in connection with the Separation (see Note 1 to the financial statements for more information)

▪ the completion of the Combination in exchange for 23.3 million common shares and 13.9 million OP Units (see Note 3 to the financial statements for more information);

▪ the closing of a $1.4 billion credit facility, consisting of a $1.0 billion revolving credit facility with a four-year term, with twosix-month extension options, a five and a half-year delayed draw $200.0 million unsecured term loan and a seven-year delayed draw $200.0 million unsecured term loan;

▪ the prepayment of mortgages payable with an aggregate principal balance of $181.7 million; and

▪ the investment of $115.9 million in development costs, construction in progress and real estate additions.

Critical Accounting Policies and Estimates

Our Information Statement on Form 10, as amended, filed with the SEC on June 20, 2017 contains a description of our critical accounting policies, including real estate, deferred costs, revenue recognition and income taxes. For the three and nine months ended September 30, 2017, there were no material changes to these policies, except for the addition of the following policy:

Business Combinations

We account for business combinations, including the acquisition of real estate, using the acquisition method by recognizing and measuring the identifiable assets acquired, liabilities assumed, and any noncontrolling interests in the acquiree at their acquisition date fair values. As a result, upon the acquisition, we estimate the fair value of the acquired tangible assets (consisting of real estate, cash and cash equivalents, tenant and other receivables, investments in unconsolidated real estate ventures and other assets, as applicable), identified intangible assets and liabilities (consisting of the value of in-place leases, above- and below-market leases, options to enter into ground leases and management contracts, as applicable), assumed debt and other liabilities, and noncontrolling interests, as applicable, based on our evaluation of information and estimates available at that date. Based on these estimates, we allocate the purchase price to the identified assets acquired and liabilities assumed. Any excess of the purchase price over the estimated fair value of the net assets acquired is recorded as goodwill. Any excess of the fair value of assets acquired over the purchase price is recorded as a gain on bargain purchase. If, up to one year from the acquisition date, information regarding the fair value of the net assets acquired and liabilities assumed is received and estimates are refined, appropriate adjustments are made on a prospective basis to the purchase price allocation, which may include adjustments to identified assets, assumed liabilities, and goodwill or the gain on bargain purchase, as applicable. Transaction costs related to business combinations are expensed as incurred and included in "Transaction and other costs" in our statements of operations.

The fair values of tangible real estate assets are determined using the “as-if vacant” approach whereby we use discounted income, or cash flow models with inputs and assumptions that we believe are consistent with current market conditions for similar assets. The most significant assumptions in determining the allocation of the purchase price to tangible assets are the exit capitalization rate, discount rate, estimated market rents and hypothetical expected lease-up periods.

The fair values of identified intangible assets are determined based on the following:

38

• The value allocable to the above- or below-market component of an acquired in-place lease is determined based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between (i) the contractual amounts to be received pursuant to the lease over its remaining term and (ii) management’s estimate of the amounts that would be received using market rates over the remaining term of the lease. Amounts allocated to above- market leases are recorded as "Identified intangible assets" in "Other assets, net" in the balance sheets, and amounts allocated to below-market leases are recorded as "Lease intangible liabilities" in "Other liabilities, net" in the balance sheets. These intangibles are amortized to "Property rentals" in our statements of operations over the remaining terms of the respective leases.

• Factors considered in determining the value allocable to in-place leases include estimates, during hypothetical lease-up periods, related to space that is actually leased at the time of acquisition. These estimates include (i) lost rent at market rates, (ii) fixed operating costs that will be recovered from tenants and (iii) theoretical leasing commissions required to execute similar leases. These intangible assets are recorded as "Identified intangible assets" in "Other assets, net" in the balance sheets and are amortized over the remaining term of the existing lease.

• The fair value of the in-place property management, leasing, asset management, and development and construction management contracts is based on revenue and expense projections over the estimated life of each contract discounted using a market discount rate. These management contract intangibles are amortized over the weighted average life of the management contracts.

The fair value of investments in unconsolidated real estate ventures and related noncontrolling interests is based on the estimated fair values of the identified assets acquired and liabilities assumed of each entity.

The fair value of the mortgages payable assumed was determined using current market interest rates for comparable debt financings. The fair values of the interest rate swaps and caps are based on the estimated amounts we would receive or pay to terminate the contract at the reporting date and are determined using interest rate pricing models and observable inputs. The carrying value of cash, restricted cash, working capital balances, leasehold improvements and equipment, and other assets acquired and liabilities assumed approximates fair value.

The results of operations of acquisitions are included in our financial statements as of the dates they are acquired. The intangible assets and liabilities associated with acquisitions are included in "Other assets, net" and "Other liabilities, net", respectively, in our balance sheets.

______________

* Not meaningful.

Property rentals revenue increased by approximately $13.2 million, or 12.8%, to $116.5 million in 2017 from $103.3 million in 2016. The increase was primarily due to revenues of $13.8 million associated with the assets acquired in the Combination, partially offset by a decrease of $0.6 million in revenues associated with existing assets. The $0.6 million decrease in revenues associated with existing assets is primarily due to 1150 17th St and 1770 Crystal Drive being taken out of service, partially offset by an increase in occupancy and associated rentals at The Bartlett which was placed into service in the second quarter of 2016.

Tenant reimbursements revenue decreased by approximately $600,000, or 6.2%, to $9.6 million in 2017 from $10.2 million in 2016. Revenue associated with existing assets decreased $2.0 million, primarily due to lower construction services provided to tenants and lower operating expenses, partially offset by an increase of $1.4 million associated with the assets acquired in the Combination.

Third-party real estate services revenue, including reimbursements, increased by approximately $16.8 million, or 203.0%, to $25.1 million in 2017 from $8.3 million in 2016. The increase was primarily due to the real estate services business acquired in the Combination, partially offset by lower management fees and leasing commissions from existing arrangements with third-parties.

Depreciation and amortization expense increased by approximately $12.6 million, or 40.1%, to $44.0 million in 2017 from $31.4 million in 2016. The increase was primarily due to depreciation and amortization expense associated with the assets acquired in the Combination.

Property operating expense increased by approximately $2.3 million, or 8.6%, to $29.6 million in 2017 from $27.3 million in 2016. The increase was primarily due to property operating expenses of $4.2 million associated with the assets acquired in the Combination, partially offset by a decrease of $1.9 million associated with existing assets due primarily to lower tenant services expense and lower utilities.

Real estate tax expense increased by approximately $2.7 million, or 18.9%, to $17.2 million in 2017 from $14.5 million in 2016. The increase was primarily due to real estate tax expense of $2.1 million associated with the assets acquired in the Combination, an increase in the tax assessments and lower capitalized real estate taxes.

General and administrative expense: corporate and other decreased by approximately $300,000, or 2.9%, to $10.6 million in 2017 from $10.9 million in 2016. The decrease was due to lower marketing and general office expenses, partially offset by an increase in general operating expenses associated with the operations acquired in the Combination.

General and administrative expense: third-party real estate services increased by approximately $16.4 million, or 343.1%, to $21.2 million in 2017 from $4.8 million in 2016primarily due to the real estate services business acquired in the Combination.

40

General and administrative expense: share-based compensation related to Formation Transaction of $14.4 million in 2017 consists of expense related to share-based compensation issued in connection with the Formation Transaction.

Transaction and other costs of $104.1 million in 2017 consists primarily of fees and expenses incurred in connection with the Formation Transaction, including severance and transaction bonus expense of $34.3 million, investment banking fees of $33.6 million, legal fees of $13.1 million and accounting fees of $8.1 million.

Income (loss) from unconsolidated real estate ventures decreased by approximately $2.3 million, to a loss of $1.7 million in 2017 from income of $584,000 in 2016. The decrease was primarily due to losses from interests in real estate ventures acquired in the Combination.

Interest expense increased by approximately $2.3 million, or 17.5%, to $15.3 million for 2017 from $13.0 million in 2016. The increase was primarily due to $1.8 million of interest expense associated with the assets acquired in the Combination and lower capitalized interest related to The Bartlett which was placed into service during the second quarter of 2016, partially offset by lower interest expense associated with mortgages that were repaid.

Loss on extinguishment of debt of $689,000 in 2017 relates to the prepayment of mortgages payable.

The gain on bargain purchase of approximately $27.8 million in 2017 represents the estimated fair value of the identifiable net assets acquired in excess of the purchase consideration in the Combination. The purchase consideration was based on the fair value of the common shares and OP Units issued in the Combination. See Note 3 to the financial statements for additional information.

Net loss attributable to redeemable noncontrolling interests of approximately $8.2 million in 2017 relates to the allocation of net loss to the noncontrolling interest in JBG SMITH LP.

Property rentals revenue increased by approximately $17.4 million, or 5.8%, to $316.9 million in 2017 from $299.5 million in 2016. The increase was primarily due to revenues of $13.8 million associated with the assets acquired in the Combination and an increase of $3.6 million in revenues associated with existing assets. The $3.6 million increase in revenues associated with existing assets is primarily due to an increase in occupancy and associated rentals at The Bartlett multifamily project as the property was placed into service in the second quarter of 2016 and higher rents at 1215 S. Clark St, partially offset by a decrease in revenues at 1150 17th St and 1770 Crystal Drive, which were taken out of service.

Tenant reimbursements revenue decreased by approximately $1.2 million, or 4.5%, to $27.2 million in 2017 from $28.4 million in 2016. Revenue associated with existing assets decreased by $2.6 million, primarily due to lower construction services provided to tenants and lower operating expenses, partially offset by an increase of $1.4 million associated with the assets acquired in the Combination.

Third-party real estate services revenue, including reimbursements, increased by approximately $14.3 million, or 57.9%, to $38.9 million in 2017 from $24.6 million in 2016. The increase was primarily due to the real estate services business acquired in the Combination, partially offset by lower management fees and leasing commissions from existing arrangements with third-parties.

Depreciation and amortization expense increased by approximately $11.4 million, or 11.6%, to $109.7 million for 2017 from $98.3 million in 2016. The increase was primarily due to depreciation and amortization expense associated with the assets acquired in the Combination.

Property operating expense increased by approximately $2.2 million, or 3.0%, to $77.3 million in 2017 and from $75.1 million in 2016. The increase was primarily due to property operating expenses of $4.2 million associated with the assets acquired in the Combination, partially offset by a decrease of $2.0 million associated with existing assets due primarily to lower tenant services expense and lower utilities.

42

Real estate tax expense increased by approximately $4.3 million, or 9.8%, to $48.0 million in 2017 from $43.7 million in 2016. The increase was primarily due to real estate tax expense of $2.1 million associated with the assets acquired in the Combination, an increase in the tax assessments and lower capitalized real estate taxes.

General and administrative expense: corporate and other decreased by approximately $500,000, or 1.4%, to $35.5 million for 2017 from $36.0 million in 2016. The decrease was due to lower marketing and general office expenses, partially offset by an increase in general operating expenses associated with the operations acquired in the Combination.

General and administrative expense: third-party real estate services increased by approximately $16.1 million, or 112.7%, to $30.4 million in 2017 from $14.3 million in 2016 primarily due to the real estate services business acquired in the Combination.

General and administrative expense: share-based compensation related to Formation Transaction of $14.4 million in 2017 consists of expense related to share-based compensation issued in connection with the Formation Transaction.

Transaction and other costs of $115.2 million in 2017 consists primarily of fees and expenses incurred in connection with the Formation Transaction, including severance and transaction bonus expense of $34.3 million, investment banking fees of $33.6 million, legal fees of $13.1 million and accounting fees of $8.1 million.

Loss from unconsolidated real estate ventures increased by approximately $400,000 to $1.4 million in 2017 from $1.0 million in 2016. The increase in the loss was primarily due to losses from interests in real estate ventures acquired in the Combination, partially offset by a reduction of interest expense of approximately $1.7 million from the refinancing of the Warner Building mortgage loan in May 2016 at a lower interest rate and for a lower outstanding principal amount.

Interest expense increased by approximately $5.1 million, or 13.3%, to $43.8 million for 2017 from $38.7 million in 2016. The increase was primarily due to $1.8 million of interest expense associated with the assets acquired in the Combination and lower capitalized interest related to The Bartlett which was placed into service during the second quarter of 2016, partially offset by lower interest expense associated with mortgages that were repaid.

Loss on extinguishment of debt of $689,000 in 2017 related to the prepayment of mortgages payable.

The gain on bargain purchase of approximately $27.8 million in 2017 represents the estimated fair value of the identifiable net assets acquired in excess of the purchase consideration in the Combination. The purchase consideration was based on the fair value of the common shares and OP Units issued in the Combination. See Note 3 to the financial statements for additional information.

Net loss attributable to redeemable noncontrolling interests of approximately $2.5 million in 2017 relates to the allocation of net loss to the noncontrolling interest in JBG SMITH LP.

Funds From Operations

We believe Funds from Operations ("FFO") (when combined with the primary presentations in accordance with GAAP) is a useful supplemental measure of our operating performance that is a recognized metric used extensively by the real estate industry and, in particular, REITs. The National Association of Real Estate Investment Trusts ("NAREIT") stated in its April 2002 White Paper on Funds from Operations, "Historical cost accounting for real estate assets implicitly assumes that the value of real estate assets diminishes predictably over time. Since real estate values instead have historically risen or fallen with market conditions, many industry investors have considered presentations of operating results for real estate companies that use historical cost accounting to be insufficient by themselves."

FFO, as defined by NAREIT, is "net income (computed in accordance with GAAP), excluding gains (or losses) from sales of, or impairment charges related to, depreciable operating properties, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and real estate ventures. It states further that “adjustments for unconsolidated partnerships and joint ventures will be calculated to reflect funds from operations on the same basis.” We believe that financial analysts, investors and shareholders are better served by the clearer presentation of comparable period operating results generated from our FFO measure. Our method of calculating FFO may be different from methods used by other REITs and, accordingly, may not be comparable to such other REITs.

FFO is presented to assist investors in analyzing our operating performance. FFO (i) does not represent cash flow from operations as defined by GAAP, (ii) is not indicative of cash available to fund all cash flow needs, including the ability to make distributions, (iii) is not an alternative to cash flow as a measure of liquidity, and (iv) should not be considered as an alternative to net (loss) income (which is determined in accordance with GAAP) for purposes of evaluating our operating performance.

43

The following reflects the reconciliation of net (loss) income attributable to JBG SMITH Properties, the most directly comparable GAAP measure, to FFO for the three months ended September 30, 2017:

NOI and Same Store NOI

In this section, we present NOI, which is a non-GAAP financial measure that we use to assess a segment’s performance. The most directly comparable GAAP measure is net income (loss) attributable to JBG SMITH Properties plus depreciation and amortization expense, general and administrative expense, transaction and other costs, interest expense, gain (loss) on extinguishment of debt and income tax expense, less third-party real estate services, less reimbursements, other income, income (loss) from unconsolidated real estate ventures, interest and other (loss) income, gain on bargain purchase and noncontrolling interests. We use NOI internally as a performance measure and believe NOI provides useful information to investors regarding our financial condition and results of operations because it reflects only property related revenue (which includes base rent, tenant reimbursements and other operating revenue) less operating expense, before deferred rent and related party management fees. Management uses NOI as a supplemental performance measure for our assets and believes it provides useful information to investors because it reflects only those revenue and expense items that are incurred at the asset level, excluding non-cash items. In addition, NOI is considered by many in the real estate industry to be a useful starting point for determining the value of a real estate asset or group of assets. However, because NOI excludes depreciation and amortization and captures neither the changes in the value of our assets that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our assets, all of which have real economic effect and could materially impact the financial performance of our assets, the utility of NOI as a measure of the operating performance of our assets is limited. NOI presented by us may not be comparable to NOI reported by other REITs that define these measures differently. We believe that to facilitate a clear understanding of our operating results, NOI should be examined in conjunction with net income (loss) attributable to JBG SMITH Properties as presented in our financial statements. NOI should not be considered as an alternative to net income (loss) attributable to JBG SMITH Properties as an indication of our performance or to cash flows as a measure of liquidity or our ability to make distributions.

We also provide certain information on a "same store" basis. Information provided on a same store basis includes the results of properties that are owned, operated and stabilized for the entirety of both periods being compared except for properties for which significant redevelopment, renovation or repositioning occurred during either of the periods being compared. While there is judgment surrounding changes in designations, a property is removed from the same store pool when a property is considered to be a property under construction because it is undergoing significant redevelopment or renovation pursuant to a formal plan or is being repositioned in the market and such renovation or repositioning is expected to have a significant impact on property operating income. A development property or property under construction is moved to the same store pool once a substantial portion of the growth expected from the development or redevelopment is reflected in both the current and comparable prior year period. Acquisitions are moved into the same store pool once we have owned the property for the entirety of the comparable periods, and the property is not under significant development or redevelopment. 

For the three and nine months ended September 30, 2017, all of the JBG Assets and two Vornado Included Assets (The Bartlett and 1800 South Bell Street) were not included in the same store comparison as they were not in service or being taken out of service during portions of the periods being compared.

Same store NOI increased by $4.2 million, or 6.3%, and $6.3 million, or 3.1%, for the three and nine months ended September 30, 2017, respectively, as compared to the three and nine months ended September 30, 2016, respectively. The increase in same store

44

NOI for the three and nine months ended September 30, 2017 was primarily due to the expiration of rent abatements and higher property rental revenue from lease commencements.

Three Months Ended September 30, 2017 compared to September 30, 2016

Office: Rental revenue increased by $8.9 million, or 9.8%, to $99.5 million in 2017 from $90.6 million in 2016. NOI increased by $5.7 million, or 10.7%, to $59.4 million in 2017 from $53.7 million in 2016. The increase in revenue and NOI is primarily due to the Combination.

Multifamily: Rental revenue increased by $8.2 million, or 49.1%, to $24.9 million in 2017 from $16.7 million in 2016. NOI increased by $4.9 million, or 47.8%, to $15.2 million in 2017 from $10.3 million in 2016. The increase in revenue and NOI is primarily due to the Combination and an increase in occupancy and associated rentals at The Bartlett which was placed into service in the second quarter of 2016.

Other: Rental revenue decreased by $1.0 million, or 18.5%, to $4.3 million in 2017 from $5.3 million in 2016. Net operating income (loss) decreased by $1.6 million, or 133.8%, to a loss of $407,000 from income of $1.2 million. The decrease in revenue and net operating income (loss) is primarily due to properties which were taken out of service, including 1700 M Street and 1770 Crystal Drive.

Nine Months Ended September 30, 2017 compared to September 30, 2016

Office: Rental revenue increased by $9.7 million, or 3.7%, to $272.3 million in 2017 from $262.6 million in 2016. NOI increased by $5.7 million, or 3.6%, to $163.7 million in 2017 from $158.0 million in 2016. The increase in revenue and NOI is primarily due to the Combination and higher rents due to rent commencements at 1215 S. Clark St.

Multifamily: Rental revenue increased by $18.2 million, or 38.2%, to $65.8 million in 2017 from $47.6 million in 2016. NOI increased by $11.1 million, or 37.3%, to $41.1 million in 2017 from $30.0 million in 2016.

Liquidity and Capital Resources

Property rental income is our primary source of operating cash flow and is dependent on a number of factors including occupancy levels and rental rates, as well as our tenants’ ability to pay rent. In addition to our portfolio, we have a third-party real estate services business that provides fee-based real estate services to our real estate ventures, legacy funds formerly organized by JBG ("JBG Legacy Funds") and other third parties. Our assets provide us with a relatively consistent level of cash flow that enables us to pay operating expenses, debt service, recurring capital expenditures, dividends to shareholders and distributions to holders of OP Units. Other sources of liquidity to fund cash requirements include proceeds from financings and asset sales. We anticipate that cash flows from continuing operations over the next 12 months and proceeds from financings and asset sales, together with existing cash balances, will be adequate to fund our business operations, debt amortization, capital expenditures, dividends to shareholders and distributions to holders of OP Units.

⁽¹⁾  Includes variable rate mortgages payable with interest rate caps.

⁽²⁾  Includes variable rate mortgages payable with interest rates effectively fixed pursuant to rate swaps.

⁽³⁾  Includes mortgages payable assumed as part of the Combination. See Note 3 to the financial statements for additional information.

⁽⁴⁾  In June 2016, the mortgage loan for the Bowen Building was repaid with proceeds of a $115.6 million draw on our former parent's revolving credit facility collateralized by an interest in the property, and, accordingly, was reflected as a component of "Payable to former parent" on the combined balance sheets as of December 31, 2016. We repaid the loan with amounts drawn under our revolving credit facility collateralized by a mortgage on the property.

As of September 30, 2017, the net carrying value of real estate collateralizing our mortgages payable totaled $3.9 billion. Our mortgage loans contain covenants that limit our ability to incur additional indebtedness on these properties and in certain circumstances, require lender approval of tenant leases and/or yield maintenance upon repayment prior to maturity. As of September 30, 2017, we were in compliance with all debt covenants.

As part of the Combination, we assumed mortgages payable with an aggregate principal balance of $768.5 million. During the three months ended September 30, 2017, we repaid mortgages payable with an aggregate principal balance of $181.7 million, which includes mortgages payable totaling $63.7 million assumed in the Combination. We recognized losses on extinguishment of debt in conjunction with these repayments of $689,000 for the three and nine months ended September 30, 2017.

On July 18, 2017, we entered into a $1.4 billion credit facility, consisting of a $1.0 billion revolving credit facility maturing in July 2021, with twosix-month extension options, a delayed draw $200.0 million unsecured term loan ("Tranche A-1 Term Loan") maturing in January 2023 and a delayed draw $200.0 million unsecured term loan ("Tranche A-2 Term Loan") maturing in July 2024. The interest rate for the credit facility varies based on a ratio of our total outstanding indebtedness to a valuation of certain real property and assets and ranges (a) in the case of the revolving credit facility, from LIBOR plus 1.10% to LIBOR plus 1.50%, (b) in the case of the Tranche A-1 Term Loan, from LIBOR plus 1.20% to LIBOR plus 1.70% and (c) in the case of the Tranche A-2 Term Loan, from LIBOR plus 1.55% to LIBOR plus 2.35%.

On July 18, 2017, in connection with the Combination, we drew $115.8 million on the revolving credit facility and $50.0 million under the Tranche A-1 Term Loan. In connection with the execution of the credit facility, we incurred $11.2 million in fees and expenses.

Long-term Liquidity Requirements

Our long-term capital requirements consist primarily of maturities under our credit facility and mortgage loans, construction commitments for development and redevelopment projects and costs related to growing our business, including acquisitions. We intend to fund these requirements through a combination of sources including debt proceeds, proceeds from asset recapitalizations and sales, capital from institutional partners that desire to form real estate venture relationships with us and available cash.

Summary of Cash Flows

The following summary discussion of our cash flows is based on the statements of cash flows and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented below.

	Nine Months Ended September 30,
	2017		2016			Change
	(In thousands)
Net cash provided by operating activities	$	23,393	$	101,383		$	(77,990	)

Net cash provided by financing activities	227,319		63,040			164,279

Cash Flows for the Nine Months EndedSeptember 30, 2017

Cash and cash equivalents were $367.9 million at September 30, 2017, compared to $29.0 million at December 31, 2016, an increase of $338.9 million. This increase resulted from $23.4 million of net cash provided by operating activities, $88.2 million of net cash used in investing activities and $227.3 million of net cash provided by financing activities. Our outstanding debt was $2.1 billion at September 30, 2017, a $974.8 million increase from the balance at December 31, 2016.

Off-Balance Sheet Arrangements

Unconsolidated Real Estate Ventures

We consolidate entities in which we own less than a 100% equity interest if we have a controlling interest or are the primary beneficiary in a variable interest entity. From time to time, we may have off-balance-sheet unconsolidated real estate ventures and other unconsolidated arrangements with varying structures.

As of September 30, 2017, we have investments in and advances to unconsolidated real estate ventures totaling $285.0 million. For the majority of these investments, we exercise significant influence over, but do not control these entities and therefore account for these investments using the equity method of accounting. For a more complete description of our joint ventures, see Note 5 to the financial statements.

From time to time, we (or ventures in which we have an ownership interest) have agreed, and may in the future agree with respect to unconsolidated real estate ventures, to (1) guarantee portions of the principal, interest and other amounts in connection with their borrowings, (2) provide customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) in connection with their borrowings and (3) provide guarantees to lenders and other third parties for the completion of development projects. We customarily have agreements with our outside partners whereby the partners agree to reimburse the joint venture or us for their share of any payments made under certain of these guarantees. Amounts that may be required to be paid in future periods in relation to budget overruns or operating losses that are also included in some of our guarantees are not estimable. Guarantees (excluding environmental) terminate either upon the satisfaction of specified circumstances or repayment of the underlying debt. At times, we have agreements with our outside partners whereby we agree to reimburse our partner for their share of any payments made by them under certain guarantees. As of September 30, 2017, the aggregate amount of our principal payment guarantees was approximately $63.8 million for our unconsolidated real estate ventures.

As of September 30, 2017, we expect to fund additional capital to certain of our unconsolidated investments totaling approximately $50.6 million, which we anticipate will be primarily expended over the next two to three years.

Reconsideration events could cause us to consolidate these unconsolidated real estate ventures and partnerships in the future. We evaluate reconsideration events as we become aware of them. Some triggers to be considered are additional contributions required by each partner and each partners’ ability to make those contributions. Under certain of these circumstances, we may purchase our partner’s interest. Our unconsolidated real estate ventures are held in entities which appear sufficiently stable to meet their capital requirements; however, if market conditions worsen and our partners are unable to meet their commitments, there is a possibility we may have to consolidate these entities.

Commitments and Contingencies

Insurance

We maintain general liability insurance with limits of $200.0 million per occurrence and in the aggregate, and property and rental value insurance coverage with limits of $2.0 billion per occurrence, with sub-limits for certain perils such as floods and earthquakes on each of our properties. We also maintain coverage for terrorist acts with limits of $2.0 billion per occurrence and in the aggregate, and $2.0 billion per occurrence and in the aggregate for nuclear, biological, chemical and radiological terrorism events, as defined by the Terrorism Risk Insurance Program Reauthorization Act, which expires in December 2020. Insurance premiums are charged directly to each of the properties.

We will continue to monitor the state of the insurance market and the scope and costs of coverage for acts of terrorism. We cannot anticipate what coverage will be available on commercially reasonable terms in the future. We are responsible for deductibles and losses in excess of the insurance coverage, which could be material.

Our debt, consisting of mortgage loans secured by our properties, revolving credit facility and unsecured term loans contain customary covenants requiring adequate insurance coverage. Although we believe that we currently have adequate insurance coverage, we may not be able to obtain an equivalent amount of coverage at reasonable costs in the future. If lenders insist on greater coverage than we are able to obtain, it could adversely affect the ability to finance or refinance our properties.

50

Construction Commitments

As of September 30, 2017, we have construction in progress that will require an additional $707.8 million to complete ($611.1 million related to our consolidated entities and $96.7 million related to our unconsolidated real estate ventures at our share), based on our current plans and estimates, which we anticipate will be primarily expended over the next two to three years. These capital expenditures are generally due as the work is performed and we expect to finance them with debt proceeds, proceeds from asset recapitalizations and sales, and available cash.

Other

There are various legal actions against us in the ordinary course of business. In our opinion, the outcome of such matters will not have a material adverse effect on our financial condition, results of operations or cash flows.

As of September 30, 2017, we expect to fund additional capital to certain of our unconsolidated investments totaling approximately $50.6 million, which we anticipate will be primarily expended over the next two to three years.

Inflation

Substantially all of our office and retail leases contain provisions designed to mitigate the adverse impact of inflation. These provisions generally increase rental rates or reimbursable expenses during the terms of the lease either at (i) fixed rates, (ii) indexed escalations (based on the Consumer Price Index of other measures) or (iii) the lesser of a fixed rate or an indexed escalation. We may be adversely impacted by inflation on the leases that do not contain indexed escalation provisions or when the increases provided by the escalation provisions are less than inflation. In addition, most of our office and retail leases require the tenant to pay an allocable share of operating expenses, including common area maintenance costs, real estate taxes and insurance. We believe that inflationary increases may be at least partially offset by the contractual rent increases and expense escalations described above. Our majority multifamily properties are subject to one-year leases, which provide us with the opportunity to adjust rental rates annually and mitigate the impact of inflation. We do not believe inflation has had a material impact on our historical financial position or results of operations.

Environmental Matters

Under various federal, state and local laws, ordinances and regulations, an owner of real estate is liable for the costs of removal or remediation of certain hazardous or toxic substances on such real estate. These laws often impose such liability without regard to whether the owner knew of, or was responsible for, the presence of such hazardous or toxic substances. The costs of remediation or removal of such substances may be substantial and the presence of such substances, or the failure to promptly remediate such substances, may adversely affect the owner’s ability to sell such real estate or to borrow using such real estate as collateral. In connection with the ownership and operation of our assets, we may be potentially liable for such costs. The operations of current and former tenants at our assets have involved, or may have involved, the use of hazardous materials or generated hazardous wastes. The release of such hazardous materials and wastes could result in us incurring liabilities to remediate any resulting contamination if the responsible party is unable or unwilling to do so. In addition, our assets are exposed to the risk of contamination originating from other sources. While a property owner generally is not responsible for remediating contamination that has migrated onsite from an offsite source, the contaminant’s presence can have adverse effects on operations and the redevelopment of our assets.

Most of our assets have been subject, at some point, to environmental assessments that are intended to evaluate the environmental condition of the subject and surrounding assets. These environmental assessments generally have included a historical review, a public records review, a visual inspection of the site and surrounding assets, screening for the presence of asbestos‑containing materials, polychlorinated biphenyls and underground storage tanks and the preparation and issuance of a written report. Soil and/or groundwater testing is conducted at our assets, when necessary, to further investigate any issues raised by the initial assessment that could reasonably be expected to pose a material concern to the property or result in us incurring material environmental liabilities. They may not, however, have included extensive sampling or subsurface investigations. In each case where the environmental assessments have identified conditions requiring remedial actions required by law, we have initiated the appropriate actions.

Each of our properties has been subjected to varying degrees of environmental assessment at various times. The environmental assessments did not reveal any material environmental contamination that we believe would have a material adverse effect on our overall business, financial condition or results of operations. Nevertheless, there can be no assurance that the identification of new areas of contamination, changes in the extent or known scope of contamination, the discovery of additional sites or changes in cleanup requirements would not result in significant cost to us.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We have exposure to fluctuations in interest rates, which are sensitive to many factors that are beyond our control. Our exposure to a change in interest rates is summarized in the table below.

	2017						2016
(Amounts in thousands)	September 30,		Weighted Average Interest Rate		Effect of 1% Change in Base Rates		December 31,		Weighted Average Interest Rate

	$	389,710			$	1,614	$	167,200

_________________

⁽¹⁾  Includes variable rate mortgages payable with interest rate caps.

⁽²⁾  Includes variable rate mortgages payable with interest rates effectively fixed pursuant interest rate swaps.

The fair value of our consolidated debt is calculated by discounting the future contractual cash flows of these instruments using current risk‑adjusted rates available to borrowers with similar credit profiles based on market sources. As of September 30, 2017 and December 31, 2016, the estimated fair value of our debt was $2.1 billion and $1.2 billion, respectively. These estimates of fair value, which are made at the end of the reporting period, may be different from the amounts that may ultimately be realized upon the disposition of our financial instruments.

Hedging Activities

To manage, or hedge, our exposure to interest rate risk, we follow established risk management policies and procedures, including the use of a variety of derivative financial instruments. We do not enter into derivative instruments for speculative purposes. Derivative financial instruments, consisting of interest rate swaps and caps, are considered economic hedges, but not designated as accounting hedges, and are carried at their estimated fair value on a recurring basis with realized and unrealized gains recorded into earnings in the period in which the change occurs.

As of September 30, 2017, we had various interest rate swap and cap agreements assumed in the Combination. As of September 30, 2017, the fair value of our interest rate swaps and caps consisted of liabilities totaling $703,000 included in "Accounts payable and accrued expenses" in our balance sheet.

ITEM 4.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), that are designed to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by Rule 13a-15(b) under the Exchange Act, we carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of September 30, 2017, our disclosure controls and procedures were effective at the reasonable assurance level such that the information required to be disclosed by us in reports that we file under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms.

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, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization and Basis of Presentation and Combination

Organization and Basis of Presentation

Organization

JBG SMITH Properties ("JBG SMITH") was organized by Vornado Realty Trust ("Vornado" or "former parent") as a Maryland real estate investment trust ("REIT") on October 27, 2016 (capitalized on November 22, 2016). JBG SMITH was formed for the purpose of receiving, via the spin-off on July 17, 2017 (the "Separation"), substantially all of the assets and liabilities of Vornado’s Washington, DC segment, which operated as Vornado / Charles E. Smith, (the "Vornado Included Assets"). On July 18, 2017, JBG SMITH acquired the management business and certain assets and liabilities (the "JBG Assets") of The JBG Companies (the "Combination"). The Separation and the Combination are collectively referred to as the "Formation Transaction." Unless the context otherwise requires, all references to "we," "us," and "our," refer to the Vornado Included Assets, our predecessor and accounting acquirer, for periods prior to the Separation and to JBG SMITH for periods from and after the Separation and Combination.

Prior to the Separation from Vornado, JBG SMITH was a wholly owned subsidiary of Vornado and had no material assets or operations. Pursuant to a separation agreement, on July 17, 2017, Vornado distributed 100% of the then outstanding common shares of JBG SMITH on a pro rata basis to the holders of its common shares. Prior to such distribution by Vornado, Vornado Realty L.P. ("VRLP"), Vornado's operating partnership, distributed common limited partnership units ("OP Units") in JBG SMITH Properties LP ("JBG SMITH LP"), our operating partnership, on a pro rata basis to the holders of VRLP's common limited partnership units, consisting of Vornado and the other common limited partners of VRLP. Following such distribution by VRLP and prior to such distribution by Vornado, Vornado contributed to JBG SMITH all of the OP Units it received in exchange for common shares of JBG SMITH. Each Vornado common shareholder received one JBG SMITH common share for every two Vornado common shares held as of the close of business on July 7, 2017 (the "Record Date").  Vornado and each of the other limited partners of VRLP received one JBG SMITH LP OP Unit for every two common limited partnership units in VRLP held as of the close of business on the Record Date. Our operations are presented as if the transfer of the Vornado Included Assets had been consummated prior to all historical periods presented in the accompanying condensed consolidated and combined financial statements at the carrying amounts of such assets and liabilities reflected in Vornado’s books and records.

In connection with the Separation, JBG SMITH issued 94.7 million common shares and JBG SMITH LP issued 5.8 million OP Units to parties other than JBG SMITH. In connection with the Combination, JBG SMITH issued 23.3 million common shares and JBG SMITH LP issued 13.9 million OP Units to parties other than JBG SMITH. As of the completion of the Formation Transaction there were 118.0 million JBG SMITH common shares outstanding and 19.8 million JBG SMITH LP OP Units outstanding that were owned by parties other than JBG SMITH. As of July 18, 2017 and September 30, 2017, we, as its sole general partner controlled JBG SMITH LP and owned 85.6% of its OP Units.

We own and operate a portfolio of high-quality office and multifamily assets, many of which are amenitized with ancillary retail. Our portfolio reflects our longstanding strategy of concentrating in downtown Washington, DC and other leading urban-infill submarkets with proximity to downtown Washington, DC that have high barriers to entry and key urban amenities, including being within walking distance of a Metro station. 

As of September 30, 2017, our portfolio comprised: (i) 69 operating assets comprising 51 office assets totaling over 13.7 million square feet (11.8 million square feet at our share), 14 multifamily assets totaling 6,016 units (4,232 units at our share) and four other assets totaling approximately 765,000 square feet (348,000 square feet at our share); (ii) nine assets under construction comprising four office assets totaling approximately 1.3 million square feet (1.2 million square feet at our share), four multifamily assets totaling 1,334 units (1,149 units at our share) and one other asset totaling approximately 41,100 square feet (4,100 square feet at our share; (iii) one near-term development multifamily asset totaling 433 units (303 units at our share), and (iv) 42 future development assets totaling approximately 21.3 million square feet (17.6 million square feet at our share) of estimated potential development density.

Our revenues are derived primarily from leases with office and multifamily tenants, including fixed rents and reimbursements from tenants for certain expenses such as real estate taxes, property operating expenses, and repairs and maintenance. In addition to our portfolio, we have a third-party real estate services business that provides fee-based real estate services to our real estate ventures, legacy funds formerly organized by JBG ("JBG Legacy Funds") and other third parties.

Only the U.S. federal government accounted for 10% or more of our rental revenue for the three and nine months ended September 30, 2017 and 2016, as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,
(Dollars in thousands)	2017			2016			2017			2016
U.S. federal government	$	22,492		$	27,594		$	68,869		$	74,939

Basis of Presentation

The accompanying unaudited condensed consolidated and combined financial statements and notes are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions of Form 10-Q and Article 10 of Regulation S-X. Accordingly, these unaudited condensed consolidated and combined financial statements do not contain certain information required in annual financial statements and notes as required under GAAP. In our opinion, all adjustments considered necessary for a fair presentation have been included, and all such adjustments are of a normal recurring nature. All intercompany transactions and balances have been eliminated. The results of operations for the three and nine months ended September 30, 2017 and 2016 are not necessarily indicative of the results that may be expected for a full year. These condensed consolidated and combined financial statements should be read in conjunction with our Registration Statement on Form 10, as amended, filed with the Securities and Exchange Commission (the "SEC") and declared effective on June 26, 2017 as well as the final Information Statement filed with the SEC as Exhibit 99.1 to our Current Report on Form 8-K filed on June 27, 2017.

The accompanying condensed consolidated and combined financial statements include the accounts of JBG SMITH and our wholly-owned subsidiaries and those other entities in which we have a controlling financial interest, including where we have been determined to be a primary beneficiary of a variable interest entity ("VIE"). See Note 6 for more information on our consolidated VIEs. The portions of the equity and net (loss) income of consolidated subsidiaries that are not attributable to JBG SMITH are presented separately as amounts attributable to noncontrolling interests in the condensed consolidated and combined financial statements.

Combination

JBG SMITH and the Vornado Included Assets were under common control of Vornado for all periods prior to the Separation at July 17, 2017. The transfer of the Vornado Included Assets from Vornado to JBG SMITH was completed prior to the Separation, at net book values (historical carrying amounts) carved out from Vornado’s books and records. For purposes of the formation of JBG SMITH, the Vornado Included Assets were designated as the predecessor and the accounting acquirer of JBG SMITH. Consequently, the financial statements of JBG SMITH, as set forth herein, represent a continuation of the financial information of the Vornado Included Assets as the predecessor and accounting acquirer such that the historical financial information included herein as of any date or for any periods on or prior to the completion of the Combination represents the pre-Combination financial information of the Vornado Included Assets. The financial statements reflect the common shares as of the date of the Separation as outstanding for all prior periods prior to July 17, 2017. The acquisition of the management business and certain assets and liabilities of JBG completed subsequently by JBG SMITH was accounted for as a business combination using the acquisition method whereby identifiable assets acquired and liabilities assumed are recorded at the acquisition-date fair values and income and cash flows from the operations were consolidated into the financial statements of JBG SMITH commencing July 18, 2017.

The accompanying condensed consolidated and combined statements of operations for the three and nine months ended September 30, 2017 include our consolidated accounts and the combined accounts of the Vornado Included Assets. Accordingly, the results of operations for the three and nine months ended September 30, 2017 reflect the aggregate operations and changes in cash flows and equity on a combined basis for all periods prior to July 17, 2017 and on a consolidated basis for all periods subsequent to July 17, 2017. The accompanying condensed combined financial statements for the three and nine months ended September 30, 2016 include the Vornado Included Assets. Therefore, the discussion of our results of operations, cash flows and financial condition set forth in this report is not necessarily indicative of our future results of operations, cash flows or financial condition as an independent, publicly traded company.

References to the financial statements refer to our condensed consolidated and combined financial statements as of September 30, 2017 and December 31, 2016, and for the three and nine months ended September 30, 2017 and 2016. References to the balance sheets refer to our condensed consolidated and combined balance sheets as of September 30, 2017 and December 31, 2016. References to the statement of operations refer to our condensed consolidated and combined statements of operations for the three and nine months ended September 30, 2017 and 2016. References to the statement of cash flows refer to our condensed consolidated and combined statements of cash flows for the nine months ended September 30, 2017 and 2016.

The historical financial results for the Vornado Included Assets reflect charges for certain corporate costs allocated by the former parent which we believe are reasonable. These charges were based on either actual costs incurred or a proportion of costs estimated to be applicable to the Vornado Included Assets based on an analysis of key metrics, including total revenues. Such costs do not necessarily reflect what the actual costs would have been if JBG SMITH had been operating as a separate standalone public company. These charges are discussed further in Note 17.

Recasting of 2016 Financial Information

The historical financial information of the Vornado Included Assets was recast to exclude Vornado's interest in Rosslyn Plaza as it was omitted from the Separation. Financial information disclosed herein as of any date or for any periods on or prior to the completion of the Separation represents such recast amounts.

Reclassifications

Certain prior period data have been reclassified to conform to the current period presentation as follows:

• Reclassification of $4.0 million of investments to "Other assets" on our balance sheet as of December 31, 2016 as a result of the revision in the line item "Investments in and advances to unconsolidated real estate ventures" on our balance sheet to include only real estate investments.

• Reclassification of $4.8 million and $14.3 million of expenses for the three and nine months ended September 30, 2016, respectively, to “General and administrative: third-party real estate services” from “Property operating expenses” as it relates to known expenses incurred to operate our third-party real estate services. Additionally, we reclassified $2.0 million and $6.0 million of income for the three and nine months ended September 30, 2016, respectively, to “Third-party real estate services, including reimbursements” from “Other income” as it relates to revenue earned from our third-party business.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Use of Estimates

The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Business Combinations

We account for business combinations, including the acquisition of real estate, using the acquisition method by recognizing and measuring the identifiable assets acquired, liabilities assumed, and any noncontrolling interests in the acquiree at their acquisition date fair values. As a result, upon the acquisition, we estimate the fair value of the acquired tangible assets (consisting of real estate, cash and cash equivalents, tenant and other receivables, investments in unconsolidated real estate ventures and other assets, as applicable), identified intangible assets and liabilities (consisting of the value of in-place leases, above- and below-market leases, options to enter into ground lease and management contracts, as applicable), assumed debt and other liabilities, and noncontrolling interests, as applicable, based on our evaluation of information and estimates available at that date. Based on these estimates, we allocate the purchase price to the identified assets acquired and liabilities assumed. Any excess of the purchase price over the estimated fair value of the net assets acquired is recorded as goodwill. Any excess of the fair value of assets acquired over the purchase price is recorded as a gain on bargain purchase. If, up to one year from the acquisition date, information regarding the fair value of the net assets acquired and liabilities assumed is received and estimates are refined, appropriate adjustments are made on a prospective basis to the purchase price allocation, which may include adjustments to identified assets, assumed liabilities, and goodwill or the gain on bargain purchase, as applicable. Transaction costs related to business combinations are expensed as incurred and included in "Transaction and other costs" in our statements of operations.

The fair values of tangible real estate assets are determined using the “as-if vacant” approach whereby we use discounted income, or cash flow models with inputs and assumptions that we believe are consistent with current market conditions for similar assets. The most significant assumptions in determining the allocation of the purchase price to tangible assets are the exit capitalization rate, discount rate, estimated market rents and hypothetical expected lease-up periods.

The fair values of identified intangible assets are determined based on the following:

• The value allocable to the above- or below-market component of an acquired in-place lease is determined based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between (i) the contractual amounts to be received pursuant to the lease over its remaining term and (ii) management’s estimate of the amounts that would be received using market rates over the remaining term of the lease. Amounts allocated to above- market leases are recorded as "Identified intangible assets" in "Other assets, net" in the balance sheets, and amounts allocated to below-market leases are recorded as "Lease intangible liabilities" in "Other liabilities, net" in the balance sheets. These intangibles are amortized to "Property rentals" in our statements of operations over the remaining terms of the respective leases.

• Factors considered in determining the value allocable to in-place leases include estimates, during hypothetical lease-up periods, related to space that is actually leased at the time of acquisition. These estimates include (i) lost rent at market rates, (ii) fixed operating costs that will be recovered from tenants and (iii) theoretical leasing commissions required to execute similar leases. These intangible assets are recorded as "Identified intangible assets" in "Other assets, net" in the balance sheets and are amortized over the remaining term of the existing lease.

• The fair value of the in-place property management, leasing, asset management, and development and construction management contracts is based on revenue and expense projections over the estimated life of each contract discounted using a market discount rate. These management contract intangibles are amortized over the weighted average life of the management contracts.

The fair value of investments in unconsolidated real estate ventures and related noncontrolling interests is based on the estimated fair values of the identified assets acquired and liabilities assumed of each entity.

The fair value of the mortgages payable assumed was determined using current market interest rates for comparable debt financings. The fair values of the interest rate swaps and caps are based on the estimated amounts we would receive or pay to terminate the contract at the reporting date and are determined using interest rate pricing models and observable inputs. The carrying value of cash, restricted cash, working capital balances, leasehold improvements and equipment, and other assets acquired and liabilities assumed approximates fair value.

The results of operations of acquisitions are included in our financial statements as of the dates they are acquired. The intangible assets and liabilities associated with acquisitions are included in "Other assets, net" and "Other liabilities, net", respectively, in our balance sheets.

Real Estate

Real estate is carried at cost, net of accumulated depreciation and amortization. Maintenance and repairs are expensed as incurred. As real estate is undergoing redevelopment activities, all property operating expenses directly associated with and attributable to the redevelopment, including interest expense, are capitalized to the extent that we believe such costs are recoverable through the value of the property. The capitalization period begins when redevelopment activities are underway and ends when the project is substantially complete. General and administrative costs are expensed as incurred. Depreciation requires an estimate by management of the useful life of each property and improvement as well as an allocation of the costs associated with a property to its various components. Depreciation is recognized on a straight‑line basis over estimated useful lives, which range from three to 40 years. Tenant allowances are amortized on a straight‑line basis over the lives of the related leases, which approximate the useful lives of the tenant improvements.

Construction in progress, including land, is carried at cost, and no depreciation is recorded. Real estate undergoing significant renovations and improvements is considered under development. All direct and indirect costs related to development activities are capitalized into "Construction in progress, including land" on our balance sheets, except for certain demolition costs, which are expensed as incurred. Costs incurred include pre-development expenditures directly related to a specific project, development and construction costs, interest, insurance and real estate taxes. Indirect development costs include employee salaries and benefits, travel and other related costs that are directly associated with the development real estate. Our method of calculating capitalized interest expense is based upon applying our weighted average borrowing rate to the actual accumulated expenditures if the property does not have property specific debt. The capitalization of such expenses ceases when the real estate is ready for its intended use, but no later than one-year from substantial completion of major construction activity. If we determine that a project is no longer viable, all pre-development project costs are immediately expensed. Similar costs related to properties not under development are expensed as incurred.

Our assets and related intangible assets are individually reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment exists when the carrying amount of an asset exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. Estimates of future cash flows are based on our current plans, intended holding periods and available market information at the time the analyses are prepared. An impairment loss is recognized only if the carrying amount of the asset is not recoverable and is measured based on the excess of the property’s carrying amount over its estimated fair value. If our estimates of future cash flows, anticipated holding periods, or fair values change, based on market conditions or otherwise, our evaluation of impairment charges may be different and such differences could be material to our financial statements. Estimates of future cash flows are subjective and are based, in part, on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results.

Real Estate Held for Sale

Real estate held for sale is recorded at the lower of the carrying amount or the expected sales price less costs to sell. Operations of real estate held for sale and real estate sold are reported in continuing operations if their disposition does not represent a strategic shift that has or will have a major effect on our operations and financial results.

The application of the accounting principles that govern the classification any of our real estate as held for sale requires management to make certain significant judgments. In evaluating whether real estate meets the held for sale criteria set forth by the Property, Plant and Equipment Topic of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC"), we make a determination as to the point in time that it is probable that a sale will be consummated. Given the nature of all real estate sales contracts, it is not unusual for such contracts to allow potential buyers a period of time to evaluate the property prior to formal acceptance of the contract. In addition, certain other matters critical to the final sale, such as financing arrangements, often remain pending even upon contract acceptance. As a result, real estate under contract may not close within the expected time period or may not close at all. Therefore, any real estate categorized as held for sale represents only those properties that management has determined are probable to close within the requirements set forth in the Property, Plant and Equipment Topic of the FASB ASC.

We do not have any real estate classified as held for sale as of September 30, 2017 and December 31, 2016.

Cash and Cash Equivalents

Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less and are carried at cost, which approximates fair value, due to their short‑term maturities.

Restricted Cash

Restricted cash consists primarily of security deposits held on behalf of our tenants, cash escrowed under loan agreements for debt service, real estate taxes, property insurance and capital improvements.

Allowance for Doubtful Accounts

We periodically evaluate the collectability of amounts due from tenants, including the receivable arising from deferred rent receivable, and maintain an allowance for doubtful accounts for the estimated losses resulting from the inability of tenants to make required payments under lease agreements. We exercise judgment in establishing these allowances and consider payment history and current credit status in developing these estimates.

Investments in and Advances to Real Estate Ventures

We analyze our real estate ventures to determine whether the respective entities should be consolidated. If it is determined that these investments do not require consolidation because the entities are not VIEs in accordance with the Consolidation Topic of the FASB ASC, we are not considered the primary beneficiary of the entities determined to be VIEs, we do not have voting control, and/or the limited partners (or non-managing members) have substantive participatory rights, then the selection of the accounting method used to account for our investments in unconsolidated real estate ventures is generally determined by our voting interests and the degree of influence we have over the entity. Management uses its judgment when determining if we are the primary beneficiary of, or have a controlling financial interest in, an entity in which we have a variable interest. Factors considered in determining whether we have the power to direct the activities that most significantly impact the entity’s economic performance include risk and reward sharing, experience and financial condition of the other partners, voting rights, involvement in day-to-day capital and operating decisions and the extent of our involvement in the entity.

We use the equity method of accounting for investments in unconsolidated real estate ventures when we own 20% or more of the voting interests and have significant influence but do not have a controlling financial interest, or if we own less than 20% of the voting interests but have determined that we have significant influence. Under the equity method, we record our investments in and advances to these entities in our balance sheets, and our proportionate share of earnings or losses earned by the real estate venture is recognized in "(Loss) income of unconsolidated real estate ventures" in the accompanying statements of operations. We earn revenues from the management services we provide to unconsolidated entities. These fees are determined in accordance with the terms specific to each arrangement and may include property and asset management fees or transactional fees for leasing, acquisition, development and construction, financing, and legal services provided. We account for this revenue gross of our ownership interest in each respective real estate venture and recognize such revenue in "Third-party real estate services, including reimbursements" in our statements of operations. Our proportionate share of related expenses is recognized in "(Loss) income of unconsolidated real estate ventures" in our statements of operations. We may also earn incremental promote distributions if certain financial return benchmarks are achieved upon ultimate disposition of the underlying properties. Management fees are recognized when earned, and promote fees are recognized when certain earnings events have occurred, and the amount is determinable and collectible. Any promote fees are reflected in "(Loss) income from unconsolidated real estate ventures" in our statements of operations.

On a periodic basis, we evaluate our investments in unconsolidated entities for impairment. We assess whether there are any indicators, including underlying property operating performance and general market conditions, that the value of our investments in unconsolidated real estate ventures may be impaired. An investment in a real estate venture is considered impaired only if we determine that its fair value is less than the net carrying value of the investment in that real estate venture on an other-than-temporary basis. Cash flow projections for the investments consider property level factors such as expected future operating income, trends and prospects, as well as the effects of demand, competition and other factors. We consider various qualitative factors to determine if a decrease in the value of our investment is other-than-temporary. These factors include age of the venture, our intent and ability to retain our investment in the entity, financial condition and long-term prospects of the entity and relationships with our partners and banks. If we believe that the decline in the fair value of the investment is temporary, no impairment charge is recorded. If our analysis indicates that there is an other-than temporary impairment related to the investment in a particular real estate venture, the carrying value of the venture will be adjusted to an amount that reflects the estimated fair value of the investment.

Intangibles

Intangible assets consist of in-place leases, below-market ground rent obligations, above-market real estate leases, lease origination costs and options to enter into ground lease that were recorded in connection with the acquisition of properties. Intangible assets also include management and leasing contracts acquired as part of the Combination. Intangible liabilities consist of above-market ground rent obligations and below-market real estate leases that are also recorded in connection with the acquisition of properties. Both intangible assets and liabilities are amortized and accreted using the straight-line method over their applicable remaining useful life. When a lease or contract is terminated early, any remaining unamortized or unaccreted balances are charged to earnings. The useful lives of intangible assets are evaluated each reporting period with any changes in estimated useful lives being accounted for over the revised remaining useful life.

Deferred Costs

Deferred financing costs consist of loan issuance costs directly related to financing transactions that are deferred and amortized over the term of the related loan as a component of interest expense. Unamortized deferred financing costs related to our mortgages payable and unsecured term loan are presented as a direct deduction from the carrying amounts of the related debt instruments, while such costs related to our revolving credit facility are included in other assets.

Direct salaries, third-party fees and other costs incurred by us to originate a lease are capitalized in "Other assets, net" in the balance sheets and are amortized against the respective leases using the straight-line method over the term of the related leases.

Noncontrolling Interests

Redeemable noncontrolling interests consists of OP Units issued in conjunction with the Formation Transaction. The OP Units are redeemable for our common shares or cash beginning August 1, 2018, subject to certain limitations. Redeemable noncontrolling interests are generally redeemable at the option of the holder and are presented in the mezzanine section between total liabilities and shareholders' equity on the balance sheets. The carrying amount of redeemable noncontrolling interests is adjusted to its redemption value at the end of each reporting period, but no less than its initial carrying value, with such adjustments recognized in "Additional paid-in capital".

Noncontrolling interests in consolidated subsidiaries represents the portion of equity that we do not own in entities we consolidate, including interests in consolidated real estate ventures or VIEs in connection with property acquisitions. We identify our noncontrolling interests separately within the equity section on the balance sheets. See Note 10 for further information.

Amounts of consolidated net (loss) income attributable to redeemable noncontrolling interests and to the noncontrolling interests in consolidated subsidiaries are presented separately in the statements of operations.

Derivative Financial Instruments and Hedge Accounting

Derivative financial instruments are used at times to manage exposure to variable interest rate risk. Derivative financial instruments, consisting of interest rate swaps and caps, are considered economic hedges, but not designated as accounting hedges, and are carried at their estimated fair value on a recurring basis. Realized and unrealized gains are recorded in "Interest and other (loss) income, net" in the statements of operations in the period in which the change occurs.

Fair Value of Assets and Liabilities

ASC 820, Fair Value Measurement and Disclosures, defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels:

Level 1 — quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities;

Level 2 — observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and

Level 3 — unobservable inputs that are used when little or no market data is available.

The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value.

Revenue Recognition

Property rentals income includes base rents that each tenant pays in accordance with the terms of its respective lease and is reported on a straight-line basis over the non-cancellable term of the lease, which includes the effects of periodic step-ups in rent and rent abatements under the leases. We commence rental revenue recognition when the tenant takes possession of the leased space or controls the physical use of the leased space and the leased space is substantially ready for its intended use. In circumstances where we provide a tenant improvement allowance for improvements that are owned by the tenant, we recognize the allowance as a reduction of property rentals revenue on a straight-line basis over the term of the lease. Differences between rental income recognized and amounts due under the respective lease agreements are recorded as an increase or decrease to “Deferred rent receivable, net” on our balance sheets. Property rentals also includes the amortization of acquired above-and below-market leases, net.

Tenant reimbursements provide for the recovery of all or a portion of the operating expenses and real estate taxes of the respective assets. Tenant reimbursements are accrued in the same periods as the related expenses are incurred.

Third-party real estate services revenue, including reimbursements, is determined in accordance with the terms specific to each arrangement and may include property and asset management fees or transactional fees for leasing, acquisition, development and construction, financing, and legal services provided. These fees are determined in accordance with the terms specific to each arrangement and are recognized as the related services are performed. Development and construction fees earned from providing services to our unconsolidated real estate joint ventures are recorded on a percentage of completion basis.

Third-Party Real Estate Services Expenses

Third-party real estate services expenses include the costs associated with the management services provided to our unconsolidated real estate joint ventures and other third parties. We allocate personnel and other overhead costs using the estimates of the time spent performing services for our third-party business and other allocation methodologies.

Income Taxes

We intend to elect to be taxed as a REIT under sections 856-860 of the Internal Revenue Code of 1986, as amended (the "Code"), commencing with the filing of our tax return for the 2017 calendar year, effective for our tax year ending December 31, 2017. Under those sections, a REIT which distributes at least 90% of its REIT taxable income as dividends to its shareholders each year and which meets certain other conditions will not be taxed on that portion of its taxable income which is distributed to its shareholders. Prior to the Separation, the Vornado Included Assets historically operated under Vornado’s REIT structure. Since Vornado operates as a REIT and distributes 100% of taxable income to its shareholders, no provision for federal income taxes has been made in the accompanying financial statements for the periods prior to the Separation. We intend to continue to adhere to these requirements and maintain our REIT status in future periods.

As a REIT, we are allowed to reduce taxable income by all or a portion of our distributions to shareholders. Future distributions will be declared and paid at the discretion of the Board of Trustees and will depend upon cash generated by operating activities, our financial condition, capital requirements, annual dividend requirements under the REIT provisions of the Code, as amended, and such other factors as our Board of Trustees deems relevant.

We also participate in certain activities conducted by entities which elected to be treated as taxable REIT subsidiaries ("TRS") under the Code. As such, we are subject to federal, state, and local taxes on the income from these activities. Income taxes attributable to our TRSs are accounted for under the asset and liability method. Under the asset and liability method, deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future.

ASC 740-10, Income Taxes, provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. ASC 740-10 requires the evaluation of tax positions taken in the course of preparing our tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold are recorded as a tax expense in the current year. As of September 30, 2017, and December 31, 2016, we determined that no liabilities are required in connection with uncertain tax positions.

(Loss) Earnings Per Share

Basic (loss) earnings per common share ("EPS") is computed by dividing net (loss) income attributable to common shareholders by the weighted average common shares outstanding during the period. Unvested and vested share-based payment awards that entitle holders to receive non-forfeitable dividends, which include OP Units, long-term incentive partnership units ("LTIP Units") and out-performance award units ("OPP Units"), are considered participating securities. Consequently, we are required to apply the two-class method of computing basic and diluted earnings that would otherwise have been available to common shareholders. Under the two-class method, earnings for the period are allocated between common shareholders and participating securities based on their respective rights to receive dividends. During periods of net loss, losses are allocated only to the extent the participating securities are required to absorb their share of such losses. Diluted earnings per common share reflects the potential dilution of the assumed exchange of various units into common shares unvested share-based payment awards to the extent they are dilutive.

Share-Based Compensation

We granted OP Units, formation awards ("Formation Awards"), LTIP Units and OPP Units to our trustees, management and employees in connection with the Separation and Combination. The term and vesting of each award were determined by the compensation committee of our Board of Trustees (the “Compensation Committee”).

Fair value is determined, depending on the type of award, using the Monte Carlo method or post-vesting restriction periods, which is intended to estimate the fair value of the awards at the grant date using dividend yields and expected volatilities that are primarily based on available implied data and peer group companies' historical data. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The shortcut method is used for determining the expected life used in the valuation method.

Compensation expense for the Formation Awards, LTIP Units, OPP Units and certain OP Units is based on the fair value of our common shares at the date of the grant and is recognized ratably over the vesting period. For grants with a graded vesting schedule that are only subject to service conditions, we have elected to recognize compensation expense on a straight-line basis.

We also elected to account for forfeitures as they occur, rather than estimate expected forfeitures. Distributions paid on unvested OP Units, LTIPs and OPPs are charged to “net income attributable to noncontrolling interests” in the statements of operations.

Recent Accounting Pronouncements

The following table provides a brief description of recent accounting pronouncements (Accounting Standards Update or "ASU") by the FASB that could have a material effect on our financial statements:

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
Standard adopted
ASU 2017‑01 Business Combinations (Topic 805): Clarifying the Definition of a Business	This standard provides a screen to determine when an asset acquired or group of assets acquired is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated.	September 2017	The adoption and implementation of this standard did not have an impact on our results of operations, financial condition or cash flows.

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
Standards not yet adopted
ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities	The standard provides new guidance for the determination of eligibility for hedge accounting and effectiveness. It also amends the presentation and disclosure requirements. ASU 2017-12 requires a modified retrospective transition method which requires the recognition of the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption.	January 2019	We are currently evaluating the overall impact of the adoption of ASU 2017-12. The adoption of this standard is not expected to have a material impact on our financial statements.
ASU 2017‑09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting	This standard clarifies which changes to the terms or conditions of a share-based payment award are subject to the guidance on modification accounting under ASC Topic 718. Entities would apply the modification accounting guidance unless the value, vesting requirements and classification of a share-based payment award are the same immediately before and after a change to the terms or conditions of the award.	January 2018	We are currently evaluating the overall impact of the adoption of ASU 2017-09. The adoption of this standard is not expected to have a material impact on our financial statements.
ASU 2017‑05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets	This standard clarifies the scope of recently established guidance on nonfinancial asset derecognition as well as the accounting for partial sales of nonfinancial assets. This update conforms the derecognition guidance on nonfinancial assets with the model for transactions in ASC 606.	January 2018	The adoption of this standard is not expected to have a material impact on our financial statements.
ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments and ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash	These standards amend the existing guidance and address specific cash flow issues with the objective of reducing existing diversity in practice. ASU 2016-15 addresses eight specific cash flow issues and ASU 2016-18 specifically addresses presentation of restricted cash and restricted cash equivalents in the statements of cash flows. These standards require a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, entities may apply the amendments prospectively as of the earliest date practicable.	January 2018	Other than the revised statement of cash flows presentation of restricted cash, the adoption of these standards is not expected to have a material impact on our financial statements.

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
ASU 2016-02, Leases (Topic 842)	This standard sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. ASU 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase. Lessees are required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. Lessees will recognize expense based on the effective interest method for finance leases or on a straight-line basis for operating leases.	January 2019	We are currently evaluating the overall impact of the adoption of ASU 2016-02 on our financial statements, including the timing of adopting this standard. ASU 2016-02 will more significantly impact the accounting for leases in which we are the lessee. We have ground leases for which we will be required to record a right-of-use asset and lease liability equal to the present value of the remaining minimum lease payments upon adoption of this standard. We also expect that this standard will have an impact on the presentation of certain lease and non‑lease components of revenue from leases with no material impact to total revenue. Under ASU 2016-02, initial direct costs for both lessees and lessors would include only those costs that are incremental to the arrangement and would not have been incurred if the lease had not been obtained. As a result, we may no longer be able to capitalize internal leasing costs and instead may be required to expense these costs as incurred.
ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as clarified and amended by ASU 2016-08, ASU 2016-10 and ASU 2016-12	This standard establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. It requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and also requires certain additional disclosures. This standard may be adopted either retrospectively or on a modified retrospective basis.	January 2018	We currently expect to utilize the modified retrospective method of adoption. We have commenced the execution of our project plan for adopting this standard, which consists of gathering and evaluating the inventory of our revenue streams. We expect this standard will have an impact on the presentation of certain lease and non-lease components of revenue from leases upon the adoption of ASU 2016‑02, Leases, with no material impact on total revenues. We expect this standard will have an impact on the timing of gains on certain sales of real estate. We are continuing to evaluate the impact of this standard on our financial statements.

Business Combinations [Abstract]

The Combination

The Combination

On July 18, 2017, we completed the Combination and acquired the JBG Assets in exchange for approximately 37.2 million common shares and OP Units. The Combination has been accounted for at fair value under the acquisition method of accounting. The following allocation of the purchase price is based on preliminary estimates and assumptions and is subject to change based on a final determination of the assets acquired and liabilities assumed (in thousands):

Fair value of purchase consideration:
Common shares and OP Units	$	1,224,886
Cash	20,573
Total consideration paid	$	1,245,459
Fair value of assets acquired and liabilities assumed:
Land and improvements	$	342,932
Building and improvements	623,889
Construction in progress, including land	632,664
Leasehold improvements and equipment	7,890
Cash	104,516
Restricted cash	13,460
Investments in and advances to unconsolidated real estate ventures	238,388
Identified intangible assets	146,600
Notes receivable (1)	50,934
Identified intangible liabilities	(8,449		)
Mortgages payable assumed (2)	(768,523		)
Capital lease obligations assumed (3)	(33,543		)
Deferred tax liability (4)	(21,476		)
Other liabilities acquired, net	(52,065		)
Noncontrolling interests in consolidated subsidiaries	(3,987		)
Net assets acquired	1,273,230
Gain on bargain purchase (5)	27,771
Total consideration paid	$	1,245,459

____________________

⁽¹⁾  During the three months ended September 30, 2017, we received proceeds of $50.9 million from the repayment of the notes receivable acquired as part of the Combination.

⁽²⁾  Subject to various interest rate swap and cap agreements assumed in the Combination that are considered economic hedges, but not designated as accounting hedges.

⁽³⁾  As part of the Combination, two ground leases were assumed that were capital leases. On July 25, 2017, we purchased a land parcel located in Reston, Virginia associated with one of the ground leases for $19.5 million.

⁽⁴⁾  Related to the management and leasing contracts acquired in the Combination.

⁽⁵⁾  The Combination resulted in a gain on bargain purchase because the estimated fair value of the identifiable net assets acquired exceeded the purchase consideration by $27.8 million. The purchase consideration was based on the fair value of the common shares and OP Units issued in the Combination. We continue to reassess the recognition and measurement of identifiable assets and liabilities acquired and have preliminarily concluded that all acquired assets and liabilities were recognized and that the valuation procedures and resulting estimates of fair values were appropriate. 

The fair value of the common shares and OP Units purchase consideration was determined as follows (in thousands, except exchange ratio and price per share/unit):

Outstanding common shares and common limited partnership units prior to the Combination	100,571
Exchange ratio (1)	2.71
Common shares and OP Units issued in consideration	37,164
Price per share/unit (2)	$	37.10
Fair value of common shares and OP Units issued in consideration	$	1,378,780
Fair value adjustment to OP Units due to transfer restrictions	(43,303		)
Portion of consideration attributable to performance of future services (3)	(110,591		)
Fair value of common shares and OP Units purchase consideration	$	1,224,886

____________________

⁽¹⁾  Represents the implied exchange ratio of one common share and OP Unit of JBG SMITH for 2.71 common shares and common limited partnership units prior to the Combination.

⁽²⁾  Represents the volume weighted average share price on July 18, 2017.

⁽³⁾  OP Unit consideration paid to certain of the owners of the JBG Assets which have an estimated fair value of $110.6 million is subject to post-combination employment with vesting over periods of either 12 or 60 months. In accordance with GAAP, consideration that is subject to future employment is not considered a component of the purchase price for the business combination and amortization is recognized as compensation expense over the period of employment and is included in "General and administrative expense: share-based compensation related to Formation Transaction" in the statements of operations.

The JBG Assets acquired comprise: (i) 30 operating assets comprising 19 office assets totaling approximately 3.6 million square feet (2.3 million square feet at our share), nine multifamily assets with 2,883 units (1,099 units at our share) and two other assets totaling approximately 490,000 square feet (73,000 square feet at our share); (ii) 11 office and multifamily assets under construction totaling over 2.5 million square feet (2.2 million square feet at our share); (iii) two near-term development office and multifamily assets totaling approximately 401,000 square feet (242,000 square feet at our share); (iv) 26 future development assets totaling approximately 11.7 million square feet (8.5 million square feet at our share) of estimated potential development density; and (v) JBG/Operating Partners, L.P., a real estate services company providing investment, development, asset management, property management, leasing, construction management and other services. JBG/Operating Partners, L.P. was owned by 20 unrelated individuals of which 19 became our employees, and three serve on our Board of Trustees.

The fair values of the depreciable tangible and identified intangible assets and liabilities, all of which have definite lives and are amortized, are as follows:  

	Total Fair Value		Weighted Average Amortization Period
				Useful Life (1)
	(In thousands)		(In years)
Tangible assets:
Building and improvements	$	559,042		3 - 40 years
Tenant improvements	64,847			Shorter of useful life or remaining life of the respective lease
Total building and improvements	$	623,889
Leasehold improvements	$	4,422		Shorter of useful life or remaining life of the respective lease
Identified intangible assets:
In-place leases	$	59,351	6.4	Remaining life of the respective lease
Above-market real estate leases	11,700		6.3	Remaining life of the respective lease
Below-market ground leases	659		88.5	Remaining life of the respective lease
Option to enter into ground lease	17,090		N/A	Remaining life of contract
Management and leasing contracts (2)	57,800		7.4	Estimated remaining life of contracts, ranging between 3 - 8 years
Total identified intangible assets	$	146,600
Identified intangible liabilities:

Variable Interest Entities

Variable Interest Entities

Unconsolidated VIEs

As of September 30, 2017 and December 31, 2016, we have interests in several investments that are deemed VIEs that are in development stage and do not hold sufficient equity at risk or conduct substantially all their operations on behalf of the investor with disproportionately few voting rights. Although we are engaged to act as the managing partner in charge of day-to-day operations of these investees, we are not the primary beneficiary of these VIEs as we do not hold unilateral power over activities that, when taken together, most significantly impact the respective VIE’s performance. We account for our investment in these entities under the equity method. As of September 30, 2017 and December 31, 2016, the net carrying amounts of our investment in these entities were $203.0 million and $42.4 million, respectively. Our maximum exposure to loss in these entities is limited to our investments, construction commitments and debt guarantees. See Note 16 for additional information.

Consolidated VIEs

JBG SMITH LP, our operating partnership, is our most significant consolidated VIE. We hold the majority membership interest in the operating partnership, act as the general partner and exercise full responsibility, discretion and control over its day-to-day management.

The noncontrolling interests of the operating partnership do not have either substantive liquidation rights, or substantive kick-out rights without cause, or substantive participating rights that could be exercised by a simple majority of noncontrolling interest members (including by such a member unilaterally). Because the noncontrolling interest holders do not have these rights, the operating partnership is a VIE. As general partner, we have the power to direct the core activities of the operating partnership that most significantly affect its performance, and through our majority interest in the operating partnership have both the right to receive benefits from and the obligation to absorb losses of the operating partnership. Accordingly, we are the primary beneficiary of the operating partnership and consolidate the operating partnership in our financial statements. As we conduct our business and hold our assets and liabilities through the operating partnership, the total assets and liabilities of the operating partnership comprise substantially all of our consolidated assets and liabilities.

We also consolidate certain VIEs that have minimal noncontrolling interests (less than 5%). These entities are VIEs because the noncontrolling interests do not have substantive kick-out or participating rights. We consolidate these entities because we control all of their significant business activities. As of September 30, 2017, the total assets and liabilities of such consolidated VIEs, excluding the operating partnership, were approximately $78.8 million and $5.1 million, respectively.

⁽³⁾  Includes mortgages payable assumed as part of the Combination. See Note 3 to the financial statements for additional information.

⁽⁴⁾  In June 2016, the mortgage loan for the Bowen Building was repaid with proceeds of a $115.6 million draw on our former parent's revolving credit facility collateralized by an interest in the property, and, accordingly, was reflected as a component of "Payable to former parent" on the combined balance sheets as of December 31, 2016. We repaid the loan with amounts drawn under our revolving credit facility collateralized by a mortgage on the property.

As of September 30, 2017, the net carrying value of real estate collateralizing our mortgages payable totaled $3.9 billion. Our mortgage loans contain covenants that limit our ability to incur additional indebtedness on these properties and in certain circumstances, require lender approval of tenant leases and/or yield maintenance upon repayment prior to maturity. As of September 30, 2017, we were in compliance with all debt covenants.

As part of the Combination, we assumed mortgages payable with an aggregate principal balance of $768.5 million. During the three months ended September 30, 2017, we repaid mortgages payable with an aggregate principal balance of $181.7 million, which includes mortgages payable totaling $63.7 million assumed in the Combination. We recognized losses on extinguishment of debt in conjunction with these repayments of $689,000 for the three and nine months ended September 30, 2017.

Credit Facility

On July 18, 2017, we entered into a $1.4 billion credit facility, consisting of a $1.0 billion revolving credit facility maturing in July 2021, with twosix-month extension options, a delayed draw $200.0 million unsecured term loan ("Tranche A-1 Term Loan") maturing in January 2023 and a delayed draw $200.0 million unsecured term loan ("Tranche A-2 Term Loan") maturing in July 2024. The interest rate for the credit facility varies based on a ratio of our total outstanding indebtedness to a valuation of certain real property and assets and ranges (a) in the case of the revolving credit facility, from LIBOR plus 1.10% to LIBOR plus 1.50%, (b) in the case of the Tranche A-1 Term Loan, from LIBOR plus 1.20% to LIBOR plus 1.70% and (c) in the case of the Tranche A-2 Term Loan, from LIBOR plus 1.55% to LIBOR plus 2.35%.

On July 18, 2017, in connection with the Combination, we drew $115.8 million on the revolving credit facility and $50.0 million under the Tranche A-1 Term Loan. In connection with the execution of the credit facility, we incurred $11.2 million in fees and expenses.

The following is a summary of amounts outstanding under the credit facility as of September 30, 2017:

Redeemable Noncontrolling Interests

Redeemable Noncontrolling Interests

In conjunction with the Formation Transaction, JBG SMITH LP issued 19.8 million OP Units to persons other than JBG SMITH that are redeemable for cash or our common shares beginning August 1, 2018, subject to certain limitations. These OP Units represent a 14.4% interest in JBG SMITH LP as of September 30, 2017. The carrying amount of the redeemable noncontrolling interests is adjusted to its redemption value at the end of each reporting period, but no less than its initial carrying value, with such adjustments recognized in "Additional paid-in capital". Redemption value is equivalent to the market value of one of our common shares at the end of the period multiplied by the number of vested OP Units outstanding. Below is a summary of the activity of redeemable noncontrolling interests for the nine months ended September 30, 2017:

OP UNITS

Certain OP Units issued as part of the Combination which have an estimated fair value of $110.6 million, are subject to post-combination employment with vesting over periods of either 12 or 60 months. The fair value of these 3.3 million OP Units was estimated based on the post-vesting restriction periods of the units. The significant assumptions used to value the units include expected volatilities (18.0% to 27.0% ), risk-free interest rates (1.3% to 1.5%) and post-vesting restriction periods (1 year to 3 years). Compensation expense for these units is recognized over the graded vesting period. See Note 3 for additional information. As of September 30, 2017, none of these OP Units had vested or been forfeited.

JBG SMITH 2017 Omnibus Share Plan

On June 23, 2017, our Board of Trustees adopted the JBG SMITH 2017 Omnibus Share Plan (the "Plan"), effective as of July 17, 2017, and authorized the reservation of approximately 10.3 million of our common shares pursuant to the Plan. On July 10, 2017, our then sole-shareholder approved the Plan. As of September 30, 2017, there were 6.6 million common shares available for issuance under the Plan.

Formation Awards

Pursuant to the Plan, on July 18, 2017, we granted approximately 2.7 million Formation Awards based on an aggregate notional value of approximately $100.0 million divided by the volume-weighted average price on July 18, 2017 of $37.10 per common share. The Formation Awards are structured in the form of profits interests in JBG SMITH LP that provide for a share of appreciation determined by the increase in the value of a common share at the time of conversion over the $37.10 volume-weighted average price of a common share at the time the formation unit was granted. The Formation Awards, subject to certain conditions, generally vest 25% on each of the third and fourth anniversaries and 50% on the fifth anniversary, of the closing of the Combination, subject to continued employment with JBG SMITH through each vesting date.

The value of vested Formation Awards is realized through conversion into a number of LTIP Units, and subsequent conversion into a number of OP Units determined based on the difference between $37.10 and the value of a common share on the conversion date. The conversion ratio between Formation Awards and OP Units, which starts at zero, is the quotient of (i) the excess of the value of a common share on the conversion date above the per share value at the time the Formation Award was granted over (ii) the value of a common share as of the date of conversion. This is similar to a “cashless exercise” of stock options, whereby the holder receives a number of shares equal in value to the difference between the full value of the total number of shares for which the option is being exercised and the total exercise price. Like options, Formation Awards have a finite term over which their value is allowed to increase and during which they may be converted into LTIP Units (and in turn, OP Units). Holders of Formation Awards will not receive distributions or allocations of net income or net loss prior to vesting and conversion to LTIP Units.

The fair value of the Formation Awards on the grant date was $23.7 million or $8.84 per unit estimated using Monte Carlo simulations. The significant assumptions used to value the awards include expected volatility (26.0%), dividend yield (2.3%), risk-free interest rate (2.3%) and expected life (7 years). Compensation expense for these awards is being recognized over a five-year period. As of September 30, 2017, none of these Formation Awards had vested or been forfeited.

LTIP Units

On July 18, 2017, we granted a total of 47,166 fully vested LTIP Units to the seven non-employee trustees in the notional amount of $250,000 each. The LTIP Units may not be sold while such non-employee trustee is serving on the Board. On the same date, we also granted 59,927 LTIP units to a key employee 50%, which vested immediately and 50% of which vests in equal monthly installments from the 31st to 60th months following the grant date. These LTIP Units had an aggregate fair value of $3.5 million.

On August 1, 2017, we granted approximately 302,500 LTIP Units to management and other employees under our Plan. The LTIP units vest in four equal installments on August 1 of each year, subject to continued employment. These LTIP Units were valued at a weighted average grant-fair value of $33.71 per unit. Compensation expense for these units is being recognized over a four-year period. As of September 30, 2017, none of these LTIP Units had vested or been forfeited.

The fair value of the LTIP Units was estimated based on the post-vesting restriction periods. The significant assumptions used to value the units include expected volatilities (17.0% to 19.0%), risk-free interest rates (1.3% to 1.5%) and post-vesting restriction periods (2 years to 3 years). Net income and net loss is allocated to each LTIP Unit. LTIP Unit holders have the right to convert all or a portion of vested LTIP Units into OP Units, which are then subsequently exchangeable for our common shares. LTIP Units do not have redemption rights, but any OP Units into which LTIP Units are converted are entitled to redemption rights. LTIP Units, generally, vote with the OP Units and do not have any separate voting rights except in connection with actions that would materially and adversely affect the rights of the LTIP Units.

OPP Units

On August 1, 2017, we granted approximately 605,100 OPP Units to management and other employees under the Plan. OPP Units are performance-based equity compensation pursuant to which participants have the opportunity to earn OPP units based on the relative performance of the total shareholder return ("TSR") of our common shares compared to the companies in the FTSE NAREIT Equity Office Index, over the three-year performance period beginning on the August 1, 2017 grant date, inclusive of dividends and stock price appreciation. Fifty percent of any OPP Units that are earned vest at the end of the three-year performance period and the remaining 50% on the fourth anniversary of the date of grant, subject to continued employment. Net income and net loss are allocated to each OPP Unit. The fair value of the OPP Units on the date of grant was $9.7 million or $15.95 per unit estimated using Monte Carlo simulations. The significant assumptions used to value the OPP Units include expected volatility (18.0%), dividend yield (2.3%) and risk-free interest rates (1.5%). Compensation expense for these units is being recognized over a four-year period. As of September 30, 2017, none of these OPP Units had vested or been forfeited.

As of September 30, 2017, we had $141.4 million of total unrecognized compensation expense related to unvested share-based payment arrangements (unvested OP Units, Formation Awards, LTIP Units and OPP Units). This expense is expected to be recognized over a weighted average period of 3.4 years.

Employee Benefits

We have a 401(k) defined contribution plan (the “401(k) Plan”) covering substantially all of our officers and employees which permits participants to defer compensation up to the maximum amount permitted by law. We provide a discretionary matching contribution. Employees’ contributions vest immediately and our matching contributions vest over five years. Our contributions to the 401(k) Plan for three months ended September 30, 2017 and 2016 were $401,000 and $868,000, respectively. Our contributions during the nine months endedSeptember 30, 2017 and 2016 were $3.2 million and $3.1 million, respectively.

The effect of the conversion of 13,408 and 4,518 weighted average vested OP Units for the three and nine months ended September 30, 2017 is excluded in the computation of basic and diluted loss per share, as the assumed exchange of such units for common shares on a one-for-one basis was antidilutive (the assumed conversion of these units would have no net impact on the determination of diluted earnings per share). As vested and outstanding OP Units are held by a noncontrolling interest, losses are attributable to them based on the weighted average outstanding units and are thus excluded from the numerator in calculating basic and diluted loss per share. The number of securities that were excluded from the calculation of diluted (loss) earnings per share because they were antidilutive that potentially could be dilutive in the future are included in the following table:

Future Minimum Rental Income

We lease space to tenants under operating leases that expire at various dates through the year 2036. The leases provide for the payment of fixed base rents payable monthly in advance as well as reimbursements of real estate taxes, insurance and maintenance costs. Retail leases may also provide for the payment by the lessee of additional rents based on a percentage of their sales. As of September 30, 2017, future base rental revenue under these non-cancelable operating leases excluding extension options is as follows:

Fair Value Measurements

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

As of September 30, 2017, we had various interest rate swap and cap agreements assumed in the Combination that are measured at fair value on a recurring basis. There were no interest rate swaps or caps prior to the Combination. The net unrealized gain on our interest rate swaps and caps was $467,000 for both the three and nine months ended September 30, 2017 and are included in "Interest expense" in the accompanying statements of operations. The fair values of the interest rate swaps and caps are based on the estimated amounts we would receive or pay to terminate the contract at the reporting date and are determined using interest rate pricing models and observable inputs. The interest rate swaps and caps are classified within Level 2 of the valuation hierarchy.

The following are liabilities measured at fair value on a recurring basis as of September 30, 2017:

Financial Assets and Liabilities Not Measured at Fair Value

As of September 30, 2017 and December 31, 2016, all financial instruments and liabilities were reflected in our balance sheets at amounts which, in our estimation, reasonably approximated their fair values, except for the following:

^{______________________________________} 

⁽¹⁾ The carrying amount consists of principal only.

The fair value of our mortgages payable is estimated by discounting the future contractual cash flows of these instruments using current risk-adjusted rates available to borrowers with similar credit ratings, which are provided by a third-party specialist. The fair value of the mortgages payable and unsecured term loan was determined using Level 2 inputs of the fair value hierarchy.

The fair value of our unsecured term loan is calculated based on the net present value of payments over the term of the loan using estimated market rates for similar notes and remaining terms. The fair value of the unsecured term loan was determined using Level 2 inputs of the fair value hierarchy.

Segment Reporting [Abstract]

Segment Information

Segment Information

We review operating and financial data for each property on an individual basis; therefore, each of our individual properties is a separate operating segment. As a result of the Formation Transaction, we redefined our reportable segments to be aligned with our method of internal reporting and the way our Chief Executive Officer, who is also our Chief Operating Decision Maker (“CODM”), makes key operating decisions, evaluates financial results, allocates resources and manages our business. Accordingly, we aggregate our operating segments into three reportable segments (office, multifamily, and third-party real estate services) based on the economic characteristics and nature of our assets and services. In connection therewith, we have reclassified the prior period segment financial data to conform to the current period presentation.

The CODM measures and evaluates the performance of our operating segments, with the exception of the third-party real estate services business, based on the net operating income (“NOI”) of properties within each segment. NOI includes property rental revenues and tenant reimbursements and deducts property operating expenses and real estate taxes.

With respect to the third-party real estate services business, the CODM reviews revenues streams generated by this segment (third-party real estate services, including reimbursements), as well as the expenses attributable to the segment (general and administrative: third-party real estate services), which are disclosed separately in the statements of operations. Management company assets primarily consist of management and leasing contracts with a net book value of $56.0 million classified in "Other assets, net" in the balance sheet as of September 30, 2017. Consistent with the CODM approach and our definition of NOI, the third-party real estate services operating results are excluded from the NOI data below.

The following table reflects the reconciliation of net (loss) income attributable to JBG SMITH Properties to NOI for the three and nine months ended September 30, 2017 and 2016:

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Insurance

We maintain general liability insurance with limits of $200.0 million per occurrence and in the aggregate, and property and rental value insurance coverage with limits of $2.0 billion per occurrence, with sub-limits for certain perils such as floods and earthquakes on each of our properties. We also maintain coverage for terrorist acts with limits of $2.0 billion per occurrence and in the aggregate, and $2.0 billion per occurrence and in the aggregate for nuclear, biological, chemical and radiological terrorism events, as defined by the Terrorism Risk Insurance Program Reauthorization Act, which expires in December 2020. Insurance premiums are charged directly to each of the properties and are included in "Property operating expenses" in the statement of operations.

We will continue to monitor the state of the insurance market and the scope and costs of coverage for acts of terrorism. We cannot anticipate what coverage will be available on commercially reasonable terms in the future. We are responsible for deductibles and losses in excess of the insurance coverage, which could be material.

Our debt, consisting of mortgage loans secured by our properties, revolving credit facility and unsecured term loans contain customary covenants requiring adequate insurance coverage. Although we believe that we currently have adequate insurance coverage, we may not be able to obtain an equivalent amount of coverage at reasonable costs in the future. If lenders insist on greater coverage than we are able to obtain, it could adversely affect the ability to finance or refinance our properties.

Construction Commitments

As of September 30, 2017, we have construction in progress that will require an additional $707.8 million to complete ($611.1 million related to our consolidated entities and $96.7 million related to our unconsolidated real estate ventures at our share), based on our current plans and estimates, which we anticipate will be primarily expended over the next two to three years. These capital expenditures are generally due as the work is performed, and we expect to finance them with debt proceeds, proceeds from asset recapitalizations and sales, and available cash.

Environmental Matters

Each of our properties has been subjected to varying degrees of environmental assessment at various times. The environmental assessments did not reveal any material environmental contamination that we believe would have a material adverse effect on our overall business, financial condition or results of operations. Nevertheless, there can be no assurance that the identification of new areas of contamination, changes in the extent or known scope of contamination, the discovery of additional sites or changes in cleanup requirements would not result in significant cost to us.

Other

There are various legal actions against us in the ordinary course of business. In our opinion, the outcome of such matters will not have a material adverse effect on our financial condition, results of operations or cash flows.

From time to time, we (or ventures in which we have an ownership interest) have agreed, and may in the future agree, to (1) guarantee portions of the principal, interest and other amounts in connection with their borrowings, (2) provide customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) in connection with their borrowings and (3) provide guarantees to lenders and other third parties for the completion of development projects. We customarily have agreements with our outside partners whereby the partners agree to reimburse the joint venture or us for their share of any payments made under the guarantee. Amounts that may be required to be paid in future periods in relation to budget overruns or operating losses that also included in some of our guarantees are not estimable. Guarantees (excluding environmental) terminate either upon the satisfaction of specified circumstances or repayment of the underlying debt. As of September 30, 2017, the aggregate amount of our principal payment guarantees was approximately $89.0 million for our consolidated entities and $63.8 million for our unconsolidated real estate ventures.

As of September 30, 2017, we expect to fund additional capital to certain of our unconsolidated investments totaling approximately $50.6 million, , which we anticipate will be primarily expended over the next two to three years.

We are obligated under non-cancelable operating leases, primarily for ground leases on certain of our properties through 2112. As of September 30, 2017, future minimum rental payments under non-cancelable operating and capital leases are as follows:

Year ending December 31,	Amount

Transactions with Vornado

As described in Note 1 and Note 3, the accompanying financial statements present the operations of the office and multifamily assets as carved-out from the financial statements of Vornado for all periods prior to July 17, 2017.

Certain centralized corporate costs borne by Vornado for management and other services including, but not limited to, accounting, reporting, legal, tax, information technology and human resources have been allocated to the assets in the consolidated and combined financial statements based on either actual costs incurred or a proportion of costs estimated to be applicable to the Vornado Included Assets based on key metrics including total revenue. The total amounts allocated during the three months ended September 30, 2017 and 2016 were $873,000 and $4.5 million, respectively. The total amounts allocated during the nine months endedSeptember 30, 2017 and 2016 were $13.0 million and $15.2 million, respectively. These allocated amounts are included as a component of "General and administrative expense: corporate and other" expenses on the statements of operations and do not necessarily reflect what actual costs would have been if the Vornado Included Assets were a separate standalone public company. Actual costs may be materially different. Allocated amounts for the three and nine months ended September 30, 2017 and 2016 are not necessarily indicative of allocated amounts for a full year.

In connection with the Formation Transaction, we entered into an agreement with Vornado under which Vornado provides operational support for an initial period of up to two years. These services include information technology, financial reporting and payroll services. The charges for these services are based on an hourly or per transaction fee arrangement including reimbursement for overhead and out-of-pocket expenses. The total charges for both the three months and nine months endedSeptember 30, 2017 were approximately $912,000. Pursuant to an agreement, we are providing Vornado with leasing and property management services for certain of its assets that were not part of the Separation. The total revenue related to these services for both the three months and nine months endedSeptember 30, 2017 was $68,000. We believe that the terms of both of these agreements are comparable to those that would have been negotiated based on market rates.

In August 2014, we completed a $185.0 million financing of the Universal buildings, a 687,000 square foot office complex located in Washington, DC. In connection with this financing, pursuant to a note agreement dated August 12, 2014, we used a portion of the financing proceeds and made an $86.0 million loan to Vornado at LIBOR plus 2.9% due August 2019. During 2016 and 2015, Vornado repaid $4.0 million and $7.0 million of the loan receivable, respectively. At the Separation, Vornado repaid the outstanding balance of the loan and related accrued interest. As of December 31, 2016, the balance of the receivable from Vornado, including accrued interest, was $75.1 million. We recognized interest income of $130,000 and $1.8 million during the three and nine months ended September 30, 2017, respectively, and $830,000 and $2.3 million during the three and nine months ended September 30, 2016, respectively.

In connection with the development of The Bartlett, prior to the Combination, we entered into various note agreements with Vornado whereby we could borrow up to a maximum of $170.0 million. Vornado contributed these note agreements along with accrued and unpaid interest to JBG SMITH at the Separation. As of December 31, 2016, the amounts outstanding under these note agreements at were $166.5 million, and are included in "Payable to former parent" on our balance sheets. We incurred interest of $365,000 and $4.1 million during the three and nine months ended September 30, 2017, respectively, and $1.2 million and $3.0 million during the three and nine months ended September 30, 2016, respectively.

In June 2016, the $115.0 million mortgage loan (including $608,000 of accrued interest) secured by the Bowen Building, a 231,000 square foot office building located in Washington, DC, was repaid with the proceeds of a $115.6 million draw on Vornado’s revolving credit facility. The loan was repaid with amounts drawn under our revolving credit facility. See Note 8 for further information. Given that the $115.6 million draw on Vornado’s credit facility is secured by an interest in the property, such amount was included in "Payable to former parent" in our balance sheets as of December 31, 2016. We incurred interest expense of $120,000 and $1.3 million during the three and nine months ended September 30, 2017, respectively, and $457,000 and $602,000 for the three and nine months ended September 30, 2016, respectively.

We have agreements, that are terminable on the second anniversary of the Combination, with Building Maintenance Services ("BMS"), a wholly owned subsidiary of Vornado, to supervise cleaning, engineering and security services at our properties. We paid BMS $3.6 million and $9.9 million during the three and nine months ended September 30, 2017, respectively, and $3.3 million and $9.6 million during the three and nine months ended September 30, 2016, respectively, which are included in "Property operating expenses" in our statements of operations.

We entered into a consulting agreement with Mr. Schear, a member of our Board of Trustees and formerly the president of Vornado’s Washington, DC segment. The consulting agreement expires on December 31, 2017 and provides for the payment of consulting fees at the rate of $166,667 per month for the 24 months following the Separation, including after the termination of the consulting agreement. The amount due under this consulting agreement of $4.1 million was recorded as a liability in connection with the Combination. As of September 30, 2017, the remaining liability is $3.6 million. In March 2017, Vornado amended Mr. Schear’s employment agreement with Vornado to provide for the payments that Mr. Schear will receive in connection with certain post-employment services.

Fees from JBG Legacy Funds

In addition to our portfolio, we have a third-party real estate services business that provides fee-based real estate services to our real estate ventures, legacy funds formerly organized by JBG and other third parties. We provide services for the benefit of the JBG Legacy Funds that own interests in the assets retained by the JBG Legacy Funds. In connection with the contribution of the JBG Assets to us, it was determined that the general partner and managing member interests in the JBG Legacy Funds that were held by former JBG executives (and who became members of our management team and/or Board of Trustees) would not be transferred to us and remain under the control of these individuals. In addition, members of our senior management and Board of Trustees have an ownership interest in the JBG Legacy Funds and own carried interests in each fund and in certain of our joint ventures that entitles them to receive additional compensation if the fund or joint venture achieves certain return thresholds.  This third-party real estate services revenue, including reimbursements, from these JBG Legacy Funds for both the three and nine months ended September 30, 2017 was $8.4 million. 

Registration Rights Agreements

In connection with the Formation Transaction, we entered into a registration rights agreement with certain former investors in the legacy JBG funds that received our common shares in the Formation Transaction (the "Shares Registration Rights Agreement") and a separate registration rights agreement with the certain former investors in the legacy JBG funds and certain employees of JBG entities that received OP Units in the Formation Transaction (the "OP Units Registration Rights Agreement" and together with the Shares Registration Rights Agreement, the "Registration Rights Agreements"). Certain holders of common shares and OP Units who may benefit from the Registration Rights Agreements are members of our management team and/or Board of Trustees.

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Use of Estimates

Use of Estimates

The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Business Combinations

Business Combinations

We account for business combinations, including the acquisition of real estate, using the acquisition method by recognizing and measuring the identifiable assets acquired, liabilities assumed, and any noncontrolling interests in the acquiree at their acquisition date fair values. As a result, upon the acquisition, we estimate the fair value of the acquired tangible assets (consisting of real estate, cash and cash equivalents, tenant and other receivables, investments in unconsolidated real estate ventures and other assets, as applicable), identified intangible assets and liabilities (consisting of the value of in-place leases, above- and below-market leases, options to enter into ground lease and management contracts, as applicable), assumed debt and other liabilities, and noncontrolling interests, as applicable, based on our evaluation of information and estimates available at that date. Based on these estimates, we allocate the purchase price to the identified assets acquired and liabilities assumed. Any excess of the purchase price over the estimated fair value of the net assets acquired is recorded as goodwill. Any excess of the fair value of assets acquired over the purchase price is recorded as a gain on bargain purchase. If, up to one year from the acquisition date, information regarding the fair value of the net assets acquired and liabilities assumed is received and estimates are refined, appropriate adjustments are made on a prospective basis to the purchase price allocation, which may include adjustments to identified assets, assumed liabilities, and goodwill or the gain on bargain purchase, as applicable. Transaction costs related to business combinations are expensed as incurred and included in "Transaction and other costs" in our statements of operations.

The fair values of tangible real estate assets are determined using the “as-if vacant” approach whereby we use discounted income, or cash flow models with inputs and assumptions that we believe are consistent with current market conditions for similar assets. The most significant assumptions in determining the allocation of the purchase price to tangible assets are the exit capitalization rate, discount rate, estimated market rents and hypothetical expected lease-up periods.

The fair values of identified intangible assets are determined based on the following:

• The value allocable to the above- or below-market component of an acquired in-place lease is determined based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between (i) the contractual amounts to be received pursuant to the lease over its remaining term and (ii) management’s estimate of the amounts that would be received using market rates over the remaining term of the lease. Amounts allocated to above- market leases are recorded as "Identified intangible assets" in "Other assets, net" in the balance sheets, and amounts allocated to below-market leases are recorded as "Lease intangible liabilities" in "Other liabilities, net" in the balance sheets. These intangibles are amortized to "Property rentals" in our statements of operations over the remaining terms of the respective leases.

• Factors considered in determining the value allocable to in-place leases include estimates, during hypothetical lease-up periods, related to space that is actually leased at the time of acquisition. These estimates include (i) lost rent at market rates, (ii) fixed operating costs that will be recovered from tenants and (iii) theoretical leasing commissions required to execute similar leases. These intangible assets are recorded as "Identified intangible assets" in "Other assets, net" in the balance sheets and are amortized over the remaining term of the existing lease.

• The fair value of the in-place property management, leasing, asset management, and development and construction management contracts is based on revenue and expense projections over the estimated life of each contract discounted using a market discount rate. These management contract intangibles are amortized over the weighted average life of the management contracts.

The fair value of investments in unconsolidated real estate ventures and related noncontrolling interests is based on the estimated fair values of the identified assets acquired and liabilities assumed of each entity.

The fair value of the mortgages payable assumed was determined using current market interest rates for comparable debt financings. The fair values of the interest rate swaps and caps are based on the estimated amounts we would receive or pay to terminate the contract at the reporting date and are determined using interest rate pricing models and observable inputs. The carrying value of cash, restricted cash, working capital balances, leasehold improvements and equipment, and other assets acquired and liabilities assumed approximates fair value.

The results of operations of acquisitions are included in our financial statements as of the dates they are acquired. The intangible assets and liabilities associated with acquisitions are included in "Other assets, net" and "Other liabilities, net", respectively, in our balance sheets.

Real Estate

Real Estate

Real estate is carried at cost, net of accumulated depreciation and amortization. Maintenance and repairs are expensed as incurred. As real estate is undergoing redevelopment activities, all property operating expenses directly associated with and attributable to the redevelopment, including interest expense, are capitalized to the extent that we believe such costs are recoverable through the value of the property. The capitalization period begins when redevelopment activities are underway and ends when the project is substantially complete. General and administrative costs are expensed as incurred. Depreciation requires an estimate by management of the useful life of each property and improvement as well as an allocation of the costs associated with a property to its various components. Depreciation is recognized on a straight‑line basis over estimated useful lives, which range from three to 40 years. Tenant allowances are amortized on a straight‑line basis over the lives of the related leases, which approximate the useful lives of the tenant improvements.

Construction in progress, including land, is carried at cost, and no depreciation is recorded. Real estate undergoing significant renovations and improvements is considered under development. All direct and indirect costs related to development activities are capitalized into "Construction in progress, including land" on our balance sheets, except for certain demolition costs, which are expensed as incurred. Costs incurred include pre-development expenditures directly related to a specific project, development and construction costs, interest, insurance and real estate taxes. Indirect development costs include employee salaries and benefits, travel and other related costs that are directly associated with the development real estate. Our method of calculating capitalized interest expense is based upon applying our weighted average borrowing rate to the actual accumulated expenditures if the property does not have property specific debt. The capitalization of such expenses ceases when the real estate is ready for its intended use, but no later than one-year from substantial completion of major construction activity. If we determine that a project is no longer viable, all pre-development project costs are immediately expensed. Similar costs related to properties not under development are expensed as incurred.

Our assets and related intangible assets are individually reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment exists when the carrying amount of an asset exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. Estimates of future cash flows are based on our current plans, intended holding periods and available market information at the time the analyses are prepared. An impairment loss is recognized only if the carrying amount of the asset is not recoverable and is measured based on the excess of the property’s carrying amount over its estimated fair value. If our estimates of future cash flows, anticipated holding periods, or fair values change, based on market conditions or otherwise, our evaluation of impairment charges may be different and such differences could be material to our financial statements. Estimates of future cash flows are subjective and are based, in part, on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results.

Real Estate Held for Sale

Real Estate Held for Sale

Real estate held for sale is recorded at the lower of the carrying amount or the expected sales price less costs to sell. Operations of real estate held for sale and real estate sold are reported in continuing operations if their disposition does not represent a strategic shift that has or will have a major effect on our operations and financial results.

The application of the accounting principles that govern the classification any of our real estate as held for sale requires management to make certain significant judgments. In evaluating whether real estate meets the held for sale criteria set forth by the Property, Plant and Equipment Topic of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC"), we make a determination as to the point in time that it is probable that a sale will be consummated. Given the nature of all real estate sales contracts, it is not unusual for such contracts to allow potential buyers a period of time to evaluate the property prior to formal acceptance of the contract. In addition, certain other matters critical to the final sale, such as financing arrangements, often remain pending even upon contract acceptance. As a result, real estate under contract may not close within the expected time period or may not close at all. Therefore, any real estate categorized as held for sale represents only those properties that management has determined are probable to close within the requirements set forth in the Property, Plant and Equipment Topic of the FASB ASC.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less and are carried at cost, which approximates fair value, due to their short‑term maturities.

Restricted Cash

Restricted Cash

Restricted cash consists primarily of security deposits held on behalf of our tenants, cash escrowed under loan agreements for debt service, real estate taxes, property insurance and capital improvements.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts

We periodically evaluate the collectability of amounts due from tenants, including the receivable arising from deferred rent receivable, and maintain an allowance for doubtful accounts for the estimated losses resulting from the inability of tenants to make required payments under lease agreements. We exercise judgment in establishing these allowances and consider payment history and current credit status in developing these estimates.

Investments in and Advances to Real Estate Ventures

Investments in and Advances to Real Estate Ventures

We analyze our real estate ventures to determine whether the respective entities should be consolidated. If it is determined that these investments do not require consolidation because the entities are not VIEs in accordance with the Consolidation Topic of the FASB ASC, we are not considered the primary beneficiary of the entities determined to be VIEs, we do not have voting control, and/or the limited partners (or non-managing members) have substantive participatory rights, then the selection of the accounting method used to account for our investments in unconsolidated real estate ventures is generally determined by our voting interests and the degree of influence we have over the entity. Management uses its judgment when determining if we are the primary beneficiary of, or have a controlling financial interest in, an entity in which we have a variable interest. Factors considered in determining whether we have the power to direct the activities that most significantly impact the entity’s economic performance include risk and reward sharing, experience and financial condition of the other partners, voting rights, involvement in day-to-day capital and operating decisions and the extent of our involvement in the entity.

We use the equity method of accounting for investments in unconsolidated real estate ventures when we own 20% or more of the voting interests and have significant influence but do not have a controlling financial interest, or if we own less than 20% of the voting interests but have determined that we have significant influence. Under the equity method, we record our investments in and advances to these entities in our balance sheets, and our proportionate share of earnings or losses earned by the real estate venture is recognized in "(Loss) income of unconsolidated real estate ventures" in the accompanying statements of operations. We earn revenues from the management services we provide to unconsolidated entities. These fees are determined in accordance with the terms specific to each arrangement and may include property and asset management fees or transactional fees for leasing, acquisition, development and construction, financing, and legal services provided. We account for this revenue gross of our ownership interest in each respective real estate venture and recognize such revenue in "Third-party real estate services, including reimbursements" in our statements of operations. Our proportionate share of related expenses is recognized in "(Loss) income of unconsolidated real estate ventures" in our statements of operations. We may also earn incremental promote distributions if certain financial return benchmarks are achieved upon ultimate disposition of the underlying properties. Management fees are recognized when earned, and promote fees are recognized when certain earnings events have occurred, and the amount is determinable and collectible. Any promote fees are reflected in "(Loss) income from unconsolidated real estate ventures" in our statements of operations.

On a periodic basis, we evaluate our investments in unconsolidated entities for impairment. We assess whether there are any indicators, including underlying property operating performance and general market conditions, that the value of our investments in unconsolidated real estate ventures may be impaired. An investment in a real estate venture is considered impaired only if we determine that its fair value is less than the net carrying value of the investment in that real estate venture on an other-than-temporary basis. Cash flow projections for the investments consider property level factors such as expected future operating income, trends and prospects, as well as the effects of demand, competition and other factors. We consider various qualitative factors to determine if a decrease in the value of our investment is other-than-temporary. These factors include age of the venture, our intent and ability to retain our investment in the entity, financial condition and long-term prospects of the entity and relationships with our partners and banks. If we believe that the decline in the fair value of the investment is temporary, no impairment charge is recorded. If our analysis indicates that there is an other-than temporary impairment related to the investment in a particular real estate venture, the carrying value of the venture will be adjusted to an amount that reflects the estimated fair value of the investment.

Intangibles

Intangibles

Intangible assets consist of in-place leases, below-market ground rent obligations, above-market real estate leases, lease origination costs and options to enter into ground lease that were recorded in connection with the acquisition of properties. Intangible assets also include management and leasing contracts acquired as part of the Combination. Intangible liabilities consist of above-market ground rent obligations and below-market real estate leases that are also recorded in connection with the acquisition of properties. Both intangible assets and liabilities are amortized and accreted using the straight-line method over their applicable remaining useful life. When a lease or contract is terminated early, any remaining unamortized or unaccreted balances are charged to earnings. The useful lives of intangible assets are evaluated each reporting period with any changes in estimated useful lives being accounted for over the revised remaining useful life.

Deferred Costs

Deferred Costs

Deferred financing costs consist of loan issuance costs directly related to financing transactions that are deferred and amortized over the term of the related loan as a component of interest expense. Unamortized deferred financing costs related to our mortgages payable and unsecured term loan are presented as a direct deduction from the carrying amounts of the related debt instruments, while such costs related to our revolving credit facility are included in other assets.

Direct salaries, third-party fees and other costs incurred by us to originate a lease are capitalized in "Other assets, net" in the balance sheets and are amortized against the respective leases using the straight-line method over the term of the related leases.

Noncontrolling Interests

Noncontrolling Interests

Redeemable noncontrolling interests consists of OP Units issued in conjunction with the Formation Transaction. The OP Units are redeemable for our common shares or cash beginning August 1, 2018, subject to certain limitations. Redeemable noncontrolling interests are generally redeemable at the option of the holder and are presented in the mezzanine section between total liabilities and shareholders' equity on the balance sheets. The carrying amount of redeemable noncontrolling interests is adjusted to its redemption value at the end of each reporting period, but no less than its initial carrying value, with such adjustments recognized in "Additional paid-in capital".

Noncontrolling interests in consolidated subsidiaries represents the portion of equity that we do not own in entities we consolidate, including interests in consolidated real estate ventures or VIEs in connection with property acquisitions. We identify our noncontrolling interests separately within the equity section on the balance sheets. See Note 10 for further information.

Amounts of consolidated net (loss) income attributable to redeemable noncontrolling interests and to the noncontrolling interests in consolidated subsidiaries are presented separately in the statements of operations.

Derivatives Financial Instruments and Hedge Accounting

Derivative Financial Instruments and Hedge Accounting

Derivative financial instruments are used at times to manage exposure to variable interest rate risk. Derivative financial instruments, consisting of interest rate swaps and caps, are considered economic hedges, but not designated as accounting hedges, and are carried at their estimated fair value on a recurring basis. Realized and unrealized gains are recorded in "Interest and other (loss) income, net" in the statements of operations in the period in which the change occurs.

Fair Value of Assets and Liabilities

Fair Value of Assets and Liabilities

ASC 820, Fair Value Measurement and Disclosures, defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels:

Level 1 — quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities;

Level 2 — observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and

Level 3 — unobservable inputs that are used when little or no market data is available.

The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value.

Revenue Recognition

Revenue Recognition

Property rentals income includes base rents that each tenant pays in accordance with the terms of its respective lease and is reported on a straight-line basis over the non-cancellable term of the lease, which includes the effects of periodic step-ups in rent and rent abatements under the leases. We commence rental revenue recognition when the tenant takes possession of the leased space or controls the physical use of the leased space and the leased space is substantially ready for its intended use. In circumstances where we provide a tenant improvement allowance for improvements that are owned by the tenant, we recognize the allowance as a reduction of property rentals revenue on a straight-line basis over the term of the lease. Differences between rental income recognized and amounts due under the respective lease agreements are recorded as an increase or decrease to “Deferred rent receivable, net” on our balance sheets. Property rentals also includes the amortization of acquired above-and below-market leases, net.

Tenant reimbursements provide for the recovery of all or a portion of the operating expenses and real estate taxes of the respective assets. Tenant reimbursements are accrued in the same periods as the related expenses are incurred.

Third-party real estate services revenue, including reimbursements, is determined in accordance with the terms specific to each arrangement and may include property and asset management fees or transactional fees for leasing, acquisition, development and construction, financing, and legal services provided. These fees are determined in accordance with the terms specific to each arrangement and are recognized as the related services are performed. Development and construction fees earned from providing services to our unconsolidated real estate joint ventures are recorded on a percentage of completion basis.

Third-Party Real Estate Services Expenses

Third-Party Real Estate Services Expenses

Third-party real estate services expenses include the costs associated with the management services provided to our unconsolidated real estate joint ventures and other third parties. We allocate personnel and other overhead costs using the estimates of the time spent performing services for our third-party business and other allocation methodologies.

Income Taxes

Income Taxes

We intend to elect to be taxed as a REIT under sections 856-860 of the Internal Revenue Code of 1986, as amended (the "Code"), commencing with the filing of our tax return for the 2017 calendar year, effective for our tax year ending December 31, 2017. Under those sections, a REIT which distributes at least 90% of its REIT taxable income as dividends to its shareholders each year and which meets certain other conditions will not be taxed on that portion of its taxable income which is distributed to its shareholders. Prior to the Separation, the Vornado Included Assets historically operated under Vornado’s REIT structure. Since Vornado operates as a REIT and distributes 100% of taxable income to its shareholders, no provision for federal income taxes has been made in the accompanying financial statements for the periods prior to the Separation. We intend to continue to adhere to these requirements and maintain our REIT status in future periods.

As a REIT, we are allowed to reduce taxable income by all or a portion of our distributions to shareholders. Future distributions will be declared and paid at the discretion of the Board of Trustees and will depend upon cash generated by operating activities, our financial condition, capital requirements, annual dividend requirements under the REIT provisions of the Code, as amended, and such other factors as our Board of Trustees deems relevant.

(Loss) Earnings Per Share

(Loss) Earnings Per Share

Basic (loss) earnings per common share ("EPS") is computed by dividing net (loss) income attributable to common shareholders by the weighted average common shares outstanding during the period. Unvested and vested share-based payment awards that entitle holders to receive non-forfeitable dividends, which include OP Units, long-term incentive partnership units ("LTIP Units") and out-performance award units ("OPP Units"), are considered participating securities. Consequently, we are required to apply the two-class method of computing basic and diluted earnings that would otherwise have been available to common shareholders. Under the two-class method, earnings for the period are allocated between common shareholders and participating securities based on their respective rights to receive dividends. During periods of net loss, losses are allocated only to the extent the participating securities are required to absorb their share of such losses. Diluted earnings per common share reflects the potential dilution of the assumed exchange of various units into common shares unvested share-based payment awards to the extent they are dilutive.

Share-based Compensation

Share-Based Compensation

We granted OP Units, formation awards ("Formation Awards"), LTIP Units and OPP Units to our trustees, management and employees in connection with the Separation and Combination. The term and vesting of each award were determined by the compensation committee of our Board of Trustees (the “Compensation Committee”).

Fair value is determined, depending on the type of award, using the Monte Carlo method or post-vesting restriction periods, which is intended to estimate the fair value of the awards at the grant date using dividend yields and expected volatilities that are primarily based on available implied data and peer group companies' historical data. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The shortcut method is used for determining the expected life used in the valuation method.

Compensation expense for the Formation Awards, LTIP Units, OPP Units and certain OP Units is based on the fair value of our common shares at the date of the grant and is recognized ratably over the vesting period. For grants with a graded vesting schedule that are only subject to service conditions, we have elected to recognize compensation expense on a straight-line basis.

We also elected to account for forfeitures as they occur, rather than estimate expected forfeitures.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

The following table provides a brief description of recent accounting pronouncements (Accounting Standards Update or "ASU") by the FASB that could have a material effect on our financial statements:

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
Standard adopted
ASU 2017‑01 Business Combinations (Topic 805): Clarifying the Definition of a Business	This standard provides a screen to determine when an asset acquired or group of assets acquired is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated.	September 2017	The adoption and implementation of this standard did not have an impact on our results of operations, financial condition or cash flows.

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
Standards not yet adopted
ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities	The standard provides new guidance for the determination of eligibility for hedge accounting and effectiveness. It also amends the presentation and disclosure requirements. ASU 2017-12 requires a modified retrospective transition method which requires the recognition of the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption.	January 2019	We are currently evaluating the overall impact of the adoption of ASU 2017-12. The adoption of this standard is not expected to have a material impact on our financial statements.
ASU 2017‑09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting	This standard clarifies which changes to the terms or conditions of a share-based payment award are subject to the guidance on modification accounting under ASC Topic 718. Entities would apply the modification accounting guidance unless the value, vesting requirements and classification of a share-based payment award are the same immediately before and after a change to the terms or conditions of the award.	January 2018	We are currently evaluating the overall impact of the adoption of ASU 2017-09. The adoption of this standard is not expected to have a material impact on our financial statements.
ASU 2017‑05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets	This standard clarifies the scope of recently established guidance on nonfinancial asset derecognition as well as the accounting for partial sales of nonfinancial assets. This update conforms the derecognition guidance on nonfinancial assets with the model for transactions in ASC 606.	January 2018	The adoption of this standard is not expected to have a material impact on our financial statements.
ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments and ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash	These standards amend the existing guidance and address specific cash flow issues with the objective of reducing existing diversity in practice. ASU 2016-15 addresses eight specific cash flow issues and ASU 2016-18 specifically addresses presentation of restricted cash and restricted cash equivalents in the statements of cash flows. These standards require a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, entities may apply the amendments prospectively as of the earliest date practicable.	January 2018	Other than the revised statement of cash flows presentation of restricted cash, the adoption of these standards is not expected to have a material impact on our financial statements.

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
ASU 2016-02, Leases (Topic 842)	This standard sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. ASU 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase. Lessees are required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. Lessees will recognize expense based on the effective interest method for finance leases or on a straight-line basis for operating leases.	January 2019	We are currently evaluating the overall impact of the adoption of ASU 2016-02 on our financial statements, including the timing of adopting this standard. ASU 2016-02 will more significantly impact the accounting for leases in which we are the lessee. We have ground leases for which we will be required to record a right-of-use asset and lease liability equal to the present value of the remaining minimum lease payments upon adoption of this standard. We also expect that this standard will have an impact on the presentation of certain lease and non‑lease components of revenue from leases with no material impact to total revenue. Under ASU 2016-02, initial direct costs for both lessees and lessors would include only those costs that are incremental to the arrangement and would not have been incurred if the lease had not been obtained. As a result, we may no longer be able to capitalize internal leasing costs and instead may be required to expense these costs as incurred.
ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as clarified and amended by ASU 2016-08, ASU 2016-10 and ASU 2016-12	This standard establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. It requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and also requires certain additional disclosures. This standard may be adopted either retrospectively or on a modified retrospective basis.	January 2018	We currently expect to utilize the modified retrospective method of adoption. We have commenced the execution of our project plan for adopting this standard, which consists of gathering and evaluating the inventory of our revenue streams. We expect this standard will have an impact on the presentation of certain lease and non-lease components of revenue from leases upon the adoption of ASU 2016‑02, Leases, with no material impact on total revenues. We expect this standard will have an impact on the timing of gains on certain sales of real estate. We are continuing to evaluate the impact of this standard on our financial statements.

____________________

⁽¹⁾  During the three months ended September 30, 2017, we received proceeds of $50.9 million from the repayment of the notes receivable acquired as part of the Combination.

⁽²⁾  Subject to various interest rate swap and cap agreements assumed in the Combination that are considered economic hedges, but not designated as accounting hedges.

⁽³⁾  As part of the Combination, two ground leases were assumed that were capital leases. On July 25, 2017, we purchased a land parcel located in Reston, Virginia associated with one of the ground leases for $19.5 million.

⁽⁴⁾  Related to the management and leasing contracts acquired in the Combination.

⁽⁵⁾  The Combination resulted in a gain on bargain purchase because the estimated fair value of the identifiable net assets acquired exceeded the purchase consideration by $27.8 million. The purchase consideration was based on the fair value of the common shares and OP Units issued in the Combination. We continue to reassess the recognition and measurement of identifiable assets and liabilities acquired and have preliminarily concluded that all acquired assets and liabilities were recognized and that the valuation procedures and resulting estimates of fair values were appropriate. 

Schedule of Business Acquisitions by Acquisition, Equity Interest Issued or Issuable

The fair value of the common shares and OP Units purchase consideration was determined as follows (in thousands, except exchange ratio and price per share/unit):

Outstanding common shares and common limited partnership units prior to the Combination	100,571
Exchange ratio (1)	2.71
Common shares and OP Units issued in consideration	37,164
Price per share/unit (2)	$	37.10
Fair value of common shares and OP Units issued in consideration	$	1,378,780
Fair value adjustment to OP Units due to transfer restrictions	(43,303		)
Portion of consideration attributable to performance of future services (3)	(110,591		)
Fair value of common shares and OP Units purchase consideration	$	1,224,886

⁽³⁾  OP Unit consideration paid to certain of the owners of the JBG Assets which have an estimated fair value of $110.6 million is subject to post-combination employment with vesting over periods of either 12 or 60 months. In accordance with GAAP, consideration that is subject to future employment is not considered a component of the purchase price for the business combination and amortization is recognized as compensation expense over the period of employment and is included in "General and administrative expense: share-based compensation related to Formation Transaction" in the statements of operations.
