Organization and Basis of Presentation	1. Organization and Basis of Presentation Easterly Government Properties, Inc. (which may be referred to in these financial statements as the “Company,” “we,” “us,” or “our”) is a Maryland corporation that has elected to be taxed as a real estate investment trust (a “REIT”) under the Internal Revenue Code (the “Code”) commencing with its taxable year ended December 31, 2015. The operations of the Company are carried on primarily through Easterly Government Properties, LP (the “Operating Partnership”) and the wholly owned subsidiaries of the Operating Partnership. We are an internally managed REIT, focused primarily on the acquisition, development, and management of Class A commercial properties that are leased to U.S. Government agencies that serve essential functions. We generate substantially all of our revenue by leasing our properties to such agencies either directly or through the U.S. General Services Administration (the “GSA”). Our objective is to generate attractive risk-adjusted returns for our stockholders over the long term through dividends and capital appreciation. As of December 31, 2017, we wholly owned 46 operating properties in the United States, including 44 operating properties that were leased primarily to U.S. Government tenant agencies and two operating properties that were entirely leased to private tenants, encompassing approximately 3.7 million square feet (square feet unaudited herein and throughout the Notes) in the aggregate. In addition, we wholly owned three properties under development encompassing approximately 0.3 million square feet. We focus on acquiring, developing, and managing U.S. Government-leased properties that are essential to supporting the mission of the tenant agency and strive to be a partner of choice for the U.S. Government, working closely with the tenant agency to meet its needs and objectives. We were incorporated in Maryland as a corporation on October 9, 2014 and did not have any meaningful operations until the completion of the formation transactions and our initial public offering on February 11, 2015 (the “IPO”). In connection with the IPO, we engaged in certain formation transactions (the “formation transactions”) pursuant to which the Operating Partnership acquired (i) 15 properties previously owned by the Easterly Funds (as defined below) in exchange for 3,308,000 shares of common stock and 8,635,714 common units of limited partnership interests in the Operating Partnership (“common units”) (ii) 14 properties previously owned by Western Devcon, Inc., a private real estate company and a series of related entities beneficially owned by Michael P. Ibe (collectively, “Western Devcon”), in exchange for 5,759,819 common units and (iii) all of the ownership interests in the management entities (as defined below) in exchange for 1,135,406 common units. Since the IPO through December 31, 2017, we have acquired 18 additional operating properties and three development properties. Our predecessor (the “Predecessor”) means Easterly Partners, LLC and its consolidated subsidiaries prior to the IPO and formation transactions, including (i) all entities or interests in U.S. Government Properties Income and Growth Fund L.P., U.S. Government Properties Income and Growth Fund REIT, Inc. and the related feeder and subsidiary entities (collectively, “Easterly Fund I,”) (ii) all entities or interests in U.S. Government Properties Income and Growth Fund II, LP, USGP II REIT LP, USGP II (Parallel) Fund, LP and their related feeders and subsidiary entities (collectively, “Easterly Fund II” and, together with Easterly Fund I, the “Easterly Funds”) and (iii) the entities that managed the Easterly Funds, (the “management entities”). All of the Company’s assets and its operations are primarily conducted through the Operating Partnership. The Company is the sole general partner of the Operating Partnership. The Company owned 84.4% of the Operating Partnership’s common units at December 31, 2017. We believe that we have operated and have been organized in conformity with the requirements for qualification and taxation as a REIT for U.S federal income tax purposes commencing with our taxable year ended December 31, 2015. Principles of Consolidation The accompanying consolidated financial statements are presented on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company, including Easterly Government Properties TRS, LLC and Easterly Government Services, LLC, the Operating Partnership and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Upon completion of the IPO and the formation transactions, the Company succeeded to the operations of the Predecessor. Prior to the IPO, the Predecessor was under the control of Darrell W. Crate, the Chairman of our board of directors. These financial statements reflect the consolidated equity ownership structure of the Company as if the IPO and the formation transactions related to the Easterly Funds and management entities had been completed as of January 1, 2014. The formation transactions related to the Easterly Funds and the management entities were accounted for at carryover basis due to the existence of common control. Prior to the IPO, the Easterly Funds, as controlled by the Predecessor, qualified as investment companies pursuant to ASC 946 Financial Services – Investment Companies Due to the timing of the IPO and the formation transactions, the Company’s results of operations for the year ended December 31, 2015 reflect the results of operations of the Predecessor combined with the Company for the period prior to February 11, 2015, and the Company’s consolidated results for the period from February 11, 2015 through December 31, 2015.

Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Revision of Previously Reported Consolidated Financial Statements In connection with the preparation of the Company's consolidated financial statements for the year ended December 31, 2017, the Company identified an error in the estimated useful life utilized to amortize certain assets associated with three properties contributed at the time of the initial public offering in the first quarter of 2015. As a result of the error, Depreciation and amortization expense had been overstated and thereby Real estate properties, net, Intangible assets, net and Equity were understated. The Company concluded that the amounts are not material to any of its previously issued consolidated financial statements. However, to maintain proper comparability between our financial statements we have elected to revise prior periods. Accordingly, the Company has revised these balances in the accompanying consolidated financial statements as of December 31, 2016 and for the years ended December 31, 2016 and December 31, 2015 as outlined below. The effects of this revision to the consolidated financial statements are as follows (in thousands, except for per share data). Effect of Revision As of and For the Year Ended December 31, 2016 As Previously Reported Adjustment As Revised Consolidated Balance Sheet Real estate properties, net $ 901,066 $ 356 $ 901,422 Intangible assets, net $ 113,795 $ 1,078 $ 114,873 Total assets $ 1,045,463 $ 1,434 $ 1,046,897 Total equity $ 696,866 $ 1,434 $ 698,300 Consolidated Statement of Operations Depreciation and amortization $ 46,643 $ (760 ) $ 45,883 Total expenses $ 91,704 $ (760 ) $ 90,944 Net income $ 4,737 $ 760 $ 5,497 Net income available to Easterly Government Properties, Inc. $ 3,415 $ 548 $ 3,963 Net income available to Easterly Government Properties, Inc. per share: Basic $ 0.11 $ 0.02 $ 0.13 Diluted $ 0.10 $ 0.02 $ 0.12 Consolidated Statement of Comprehensive Income Comprehensive income $ 8,522 $ 760 $ 9,282 Effect of Revision For the Year Ended December 31, 2015 As Previously Reported Adjustment As Revised Consolidated Statement of Operations Depreciation and amortization $ 33,561 $ (674 ) $ 32,887 Total expenses $ 67,329 $ (674 ) $ 66,655 Net loss $ (6,045 ) $ 674 $ (5,371 ) Net loss available to Easterly Government Properties, Inc. $ (1,694 ) $ 410 $ (1,284 ) Net loss available to Easterly Government Properties, Inc. per share: Basic $ (0.08 ) $ 0.02 $ (0.06 ) Diluted $ (0.08 ) $ 0.02 $ (0.06 ) Consolidated Statement of Comprehensive Income Comprehensive loss $ (6,045 ) $ 674 $ (5,371 ) Use of Estimates The preparation of the consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the balance sheet and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant Accounting Policies In light of the significant differences that exist between our basis of accounting subsequent to the IPO (historical cost accounting) and the pre-IPO basis of accounting (investment company accounting), we present the significant accounting policies for both periods below. a) Significant Accounting Policies for the Company post-IPO Real Estate Properties Real estate properties comprise all tangible assets we hold for rent or development. Real property is recognized at cost less accumulated depreciation. Acquisition costs related to business combinations, including third party transaction and direct internal costs are expensed as incurred. Third party costs related to asset acquisitions are capitalized. Development, re-development and certain costs directly related to the improvement of real properties are capitalized. Maintenance and repair expenses are charged to expense as incurred. When we acquire properties, we allocate the purchase price to numerous tangible and intangible components. Our process for determining the allocation to these components requires many estimates and assumptions, including the following: (1) determination of market rental rates; (2) estimation of leasing and tenant improvement costs associated with the remaining term of acquired leases; (3) assumptions used in determining the in-place lease and if-vacant value including the rental rates, period of time that it would take to lease vacant space and estimated tenant improvement and leasing costs; (4) renewal probabilities; and (5) allocation of the if-vacant value between land and building. A change in any of the above key assumptions can materially change not only the presentation of acquired properties in our consolidated financial statements but also our reported results of operations. The allocation to different components affects the following: • the amount of the purchase price allocated among different categories of assets and liabilities on our consolidated balance sheets; and the amount of costs assigned to individual properties in multiple property acquisitions; • where the amortization of the components appear over time in our consolidated statements of operations. Allocations to above- and below-market leases are amortized into rental revenue, whereas allocations to most of the other tangible and intangible assets are amortized into depreciation and amortization expense. As a REIT, this is important to us since much of the investment community evaluates our operating performance using non-GAAP measures such as Funds From Operations, the computation of which includes rental revenue but does not include depreciation and amortization expense; and • the timing over which the items are recognized as revenue or expense in our consolidated statements of operations. For example, for allocations to the as-if vacant value, the land portion is not depreciated and the building portion is depreciated over a longer period of time than the other components (generally 40 years). Allocations to above- and below-market leases and in-place lease value are amortized over significantly shorter timeframes, and if individual tenants’ leases are terminated early, any unamortized amounts remaining associated with those tenants are written off upon termination. These differences in timing can materially affect our reported results of operations. Tenant improvements are capitalized in real property when we own the improvement. When we are required to provide improvements under the terms of a lease, we need to determine whether the improvements constitute landlord assets or tenant assets. If the improvements are considered landlord assets, we capitalize the cost of the improvements and recognize depreciation expense associated with such improvements over the shorter of the useful life of the assets or the term of the lease and recognize any payments from the tenant as rental revenue over the term of the lease. If the improvements are considered tenant assets, we defer the cost of improvements funded by us as a lease incentive asset and amortize it as a reduction of rental revenue over the term of the lease. Our determination of whether improvements are landlord assets or tenant assets also may affect when we commence revenue recognition in connection with a lease. In determining whether improvements constitute landlord or tenant assets, we consider numerous factors that may require subjective or complex judgments, including: whether the improvements are unique to the tenant or reusable by other tenants; whether the tenant is permitted to alter or remove the improvements without our consent or without compensating us for any lost fair value; whether the ownership of the improvements remains with us or remains with the tenant at the end of the lease term; and whether the economic substance of the lease terms is properly reflected. We capitalize pre-development costs incurred in pursuit of new development opportunities for which we currently believe future development is probable. Additionally, we capitalize interest expense, real estate taxes and direct and indirect project costs (including related compensation and other indirect costs) associated with properties, or portions thereof, undergoing construction, development and redevelopment activities. In capitalizing interest expense, if there is a specific borrowing for the property undergoing construction, development and redevelopment activities, we apply the interest rate of that borrowing to the average accumulated expenditures that do not exceed such borrowing; for the portion of expenditures exceeding any such specific borrowing, we apply our weighted average interest rate on other borrowings to the expenditures. We continue to capitalize costs while construction, development or redevelopment activities are underway until the building is substantially complete and ready for its intended use. Depreciation of an asset begins when it is available for use and is calculated using the straight-line method over the estimated useful lives. Each period, depreciation is charged to expense and credited to the related accumulated depreciation account. A used asset acquired is depreciated over its estimated remaining useful life, not to exceed the life of a new asset. Range of useful lives for depreciable assets are as follows: Category Term Buildings 40 years Building improvements 5 - 40 years Tenant improvements Shorter of remaining life of the lease or useful life Furniture and equipment 3 - 7 years We regularly evaluate whether events or changes in circumstances have occurred that could indicate an impairment in the value of long lived assets. If there is an indication that the carrying value of an asset is not recoverable, we estimate the projected undiscounted cash flows to determine if an impairment loss should be recognized. We determine the amount of any impairment loss by comparing the historical carrying value to estimated fair value. We estimate fair value through an evaluation of recent financial performance and projected discounted cash flows using standard industry valuation techniques. In addition to consideration of impairment upon the events or changes in circumstances described above, we regularly evaluate the remaining lives of our long lived assets. If we change our estimate of the remaining lives, we allocate the carrying value of the affected assets over their revised remaining lives. Cash and Cash Equivalents Cash and cash equivalents include all cash and liquid investments that mature three months or less from when they are purchased. Cash equivalents are reported at cost, which approximates fair value. We maintain our cash in bank accounts in amounts that may exceed federally insured limits at times. We have not experienced any losses in these accounts and believe that we are not exposed to significant credit risk because our accounts are deposited with major financial institutions. Restricted Cash Restricted cash consists of amounts escrowed for future real estate taxes, insurance, capital expenditures and debt service, as required by certain of our mortgage debt agreements. Rent Receivable and Accounts Receivable Rent receivable and Accounts receivable on the accompanying Consolidated Balance Sheets includes accrued rental income and other tenant accounts receivable, respectively. The Company accrues rental and other tenant income earned, but not yet receivable, in accordance with GAAP. Deferred Costs Deferred financing fees and debt issuance costs include costs incurred in obtaining debt that are capitalized and are presented as a direct deduction from the carry amount of the associated debt liability that is not a line-of-credit arrangement on the accompanying Consolidated Balance Sheets. Deferred financing fees and debt issuance costs related to line-of-credit arrangements are presented as an asset in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. The deferred financing fees and debt issuance costs are amortized through interest expense over the life of the respective loans on a basis which approximates the effective interest method. Any unamortized amounts upon early repayment of debt are written off in the period of repayment as a loss on extinguishment of debt. Fully amortized deferred financing fees and debt issuance costs are removed from the books upon maturity of the underlying debt. Deferred offering costs include certain legal, accounting and other third party fees that are directly associated with in-process equity financings until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction to capital. Should the equity financing no longer be considered probable of being consummated, the deferred offering costs would be expensed immediately as a charge to corporate general and administrative expenses in the accompanying Consolidated Statement of Operations. Deferred leasing commissions include commissions, compensation costs of leasing personnel, and other direct and incremental costs incurred to obtain new tenant leases as well as to renew existing tenant leases, and are presented in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. Leasing commission are capitalized and amortized over the terms of the related leases upon lease commencement using the straight-line method. If a lease terminates prior to the expiration of its initial term, any unamortized costs related to the lease are accelerated into amortization expense. Changes in leasing commissions are presented in the cash flows from operating activities section of the accompanying Consolidated Statements of Cash Flows. Interest Rate Swaps The Company’s primary objective in using interest rate derivatives are to add stability to interest expense and to manage exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable- rate amounts from a counterparty in exchange for our making fixed- rate payments over the life of the agreements without exchange of the underlying notional amount. Derivatives are used to hedge the cash flows associated with interest rates on existing debt as well as future debt. We recognize derivatives as assets or liabilities on the balance sheet at fair value. We defer the effective portion of changes in fair value of the designated cash flow hedges to accumulated other comprehensive income (“AOCI”) or loss (“AOCL”) and reclassify such deferrals to interest expense as interest expense is recognized on the hedged forecasted transitions. We recognize the ineffective portion of the change in fair value of interest rate derivatives directly in interest expense. When an interest rate swap designated as a cash flow hedge no longer qualified for hedge accounting, we recognize changes in fair value of the hedge previously deferred to AOCI or AOCL, along with any changes in fair value occurring thereafter, through earnings. We do not use interest rate derivatives for trading or speculative purposes. We manage counterparty risk by only entering into contracts with major financial institutions based upon their credit ratings and other risk factors. We use standard market conventions and techniques such as discounted cash flow analysis, option pricing models, replacement cost and termination cost in computing the fair value of derivatives at each balance sheet date. The Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Please refer to Note 5 for more information pertaining to interest rate derivatives. Non-Controlling Interests Non-controlling interests relate to the common units of the Operating Partnership not owned by the Company. Unitholders receive a distribution per unit equivalent to the dividend per share of the Company’s common stock. Pursuant to the consolidation accounting standard with respect to the accounting and reporting for non-controlling interest changes and changes in ownership interest of a subsidiary, changes in parent’s ownership interest when the parent retains controlling interest in the subsidiary should be accounted for as equity transactions. The carrying amount of the non-controlling interest shall be adjusted to reflect the change in its ownership interest in the subsidiary, with the offset to equity attributable to the Company. Revenue Recognition Rental income includes base rents paid by each tenant in accordance with its lease agreement conditions. We recognize rental income on a straight-line basis over the lease term of the respective leases. For acquisitions of existing buildings, we recognize rental income from leases already in place coincident with the date of property closing. Lease incentives are recorded as a deferred asset and amortized as a reduction of revenue on a straight-line basis over the respective lease term. Above- and below-market leases are amortized into rental income over the terms of the respective leases. Tenant reimbursement income (scheduled rent increases based on increases in real estate taxes, operating expenses and utility usage, projects and other reimbursements) is recognized by us in the consolidated statements of operations once services are rendered, fees are determinable and collectability is assured. We recognize revenue from tenant construction projects using the percentage of completion method when the revenue and costs for such projects can be estimated with reasonable accuracy; when these criteria do not apply to a project, we recognize revenue from that project using the completed contract method. Under the percentage of completion method, we recognize a percentage of the total estimated revenue on a project based on the cost of services provided on the project as of a point in time relative to the total estimated costs on the project. For the year ended December 31, 2017, we incurred $3.8 million in expenses associated with projects and other services that were fully reimbursed by our tenants and earned $0.6 million in associated income. For the year ended December 31, 2016, we incurred $3.8 million in expenses associated with projects and other services that were fully reimbursed by our tenants and earned $0.5 million in associated income. For the year ended December 31, 2015, we incurred $1.2 million in expenses associated with projects and other services that were fully reimbursed by our tenants and $0.2 million in associated income. Fully reimbursed income was included within “Tenant reimbursements” and associated expenses were included in “Property operating” expenses. Income on these projects was included in “Other income”. Income Taxes We believe that we have operated and have been organized in conformity with the requirements for qualification and taxation as a REIT for U.S. federal income tax purposes commencing with our taxable year ended December 31, 2015. So long as we qualify as a REIT, we generally will not be subject to U.S. federal income tax on our net income that we distribute to our stockholders. To maintain our qualification as a REIT, we are required under the Code to distribute at least 90% of our REIT taxable income (without regard to the deduction for dividends paid and excluding net capital gains) to our stockholders and meet certain other requirements. If we fail to qualify as a REIT in any taxable year, we will be subject to U.S. federal income tax on our taxable income at regular corporate rates. Even if we qualify as a REIT, we will be subject to certain U.S. federal, state and local taxes on our income and property, and on taxable income that we do not distribute to our stockholders. In addition, we may provide services that are not customarily provided by a landlord, hold properties for sale and engage in other activities (such as a management business) through Taxable REIT Subsidiaries (“TRSs”) and the income of those subsidiaries will be subject to U.S. federal income tax at regular corporate rates. For the years ended December 31, 2017, 2016 and 2015, we did not incur any material tax liability associated with any of the above. We do not anticipate any potential expense related to uncertain tax positions as we closely monitor our REIT compliance, do not have any prohibited transactions related to property sales, and neither the states in which we operate nor our foreign investors subject us to withholding tax requirements. The following table reconciles GAAP net income to taxable income: For the years ended December 31, 2017 2016 2015 Net income (loss) $ 5,389 $ 5,497 $ (5,371 ) Book depreciation and amortization 54,782 45,797 32,809 Above/Below market lease amortization (8,517 ) (7,153 ) (4,866 ) Straight-line rent and other non-cash adjustments (2,776 ) (108 ) (220 ) Book/Tax differences on offering and acquisition costs at IPO — — 2,928 Book/Tax differences on unearned rent 16 (37 ) 2,138 Book/Tax differences on stock based compensation 2,663 2,780 1,867 Book/Tax differences on post IPO property acquisition costs — 620 856 Other book/tax differences, net 383 901 (214 ) Tax depreciation (25,552 ) (20,622 ) (16,451 ) Loss attributable to non-controlling interest (5,180 ) (8,474 ) (7,956 ) Loss attributable to predecessor — — 5,581 Taxable income subject to distribution requirements $ 21,208 (1) $ 19,201 (2) $ 11,101 (3) (1) The Company’s distributions are characterized as 47.24% ordinary taxable dividend and 52.76% return of capital. (2) The Company’s distributions are characterized as 59.32% ordinary taxable dividend and 40.68% return of capital. (3) The Company’s distributions are characterized as 85.06% ordinary taxable dividend and 14.94% return of capital. Stock Based Compensation The Company grants equity-based compensation awards to its officers, employees and non-employee directors in the form of restricted shares of common stock and long-term incentive plan units in the Operating Partnership (“LTIP units”). See Note 7 (Equity) for further discussion of restricted shares of common stock and LTIP units. The restricted shares of common stock and LTIP units issued to officers, employees, and non-employee directors vest over a period of time as determined by our board of directors at the date of grant. The Company recognizes compensation expense for non-vested restricted shares of common stock and LTIP units granted to officers, employees and non-employee directors on a straight-line basis over the requisite service and/or performance period based upon the fair market value of the shares on the date of grant, as adjusted for forfeitures. Earnings Per Share of Common Stock Amount Basic earnings per share is calculated by dividing net income available to Easterly Government Properties Inc. by the weighted-average number of shares of common stock outstanding during the period, excluding the weighted average number of unvested restricted shares. Diluted earnings per share is calculated by dividing net income by the weighted-average number of shares of common stock outstanding during the period plus other potentially dilutive securities such as unvested restricted shares that would be issued in the event that common units of the Operating Partnership are redeemed for shares of common stock of the Company. Unvested restricted shares and LTIP units are considered participating securities which require the use of the two-class method for the computation of basic and diluted earnings per share. Segments The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. All revenue has been generated and all tangible assets are held in the United States. Recently Adopted Accounting Pronouncements On January 1, 2017, the Company adopted ASU 2017-01, Business Combinations (Topic 805), which clarifies the framework for determining whether an integrated set of assets and activities meets the definition of a business. The revised framework establishes a screen for determining whether an integrated set of assets and activities is a business and narrows the definition of a business, which is expected to result in fewer transactions being accounted for as business combinations. Acquisitions of integrated sets of assets and activities that do not meet the definition of a business are accounted for as asset acquisitions. As a result, the Company believes most of our future acquisitions of operating properties will qualify as asset acquisitions and third-party transaction costs associated with these acquisitions will be capitalized while internal acquisition costs will continue to be expensed. On January 1, 2017, the Company adopted ASU No. 2016-09, Compensation – Stock Compensation, which identifies areas for simplification involving several aspects of accounting for share-based payment transactions. The new guidance allows for entities to make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. In addition, the guidance allows employers to withhold shares to satisfy minimum statutory tax withholding requirements up to the employees’ maximum individual tax rate without causing the award to be classified as a liability. The guidance also stipulates that cash paid by an employer to a taxing authority when directly withholding shares for tax-withholding purposes should be classified as a financing activity on the statement of cash flows. The implementation of this update did not have an impact on our consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers and will replace most existing revenue recognition guidance when it becomes effective. This amendment applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC (“Accounting Standards Codification”). In July 2015, the FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 by one year to annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The Company will adopt ASU 2014-09 using the modified retrospective approach. The Company has evaluated the impact of this new guidance and notes the adoption of this guidance will not be material to its financial results. Additional information about the Company’s revenue streams and other considerations are summarized below. Rental income from real property is derived from rental agreements, whereby 44 of the Company’s operating properties are leased primarily to the U.S. Government and two of the Company’s operating properties are entirely leased to private tenants. Rental income from real property is specifically excluded from ASU 2014-09. Tenant reimbursements – is comprised of tenant reimbursements for real estate taxes, and certain other expenses, as well as tenant construction project reimbursements that consist primarily of subcontracted costs that are reimbursed to us by the tenant. Reimbursements from real estate taxes and certain other expenses are not included within the scope of ASU 2014-09. After adoption of ASU 2014-09, we believe that we will account for tenant construction project reimbursement arrangements using the percentage of completion method, which is the method we have used historically. Other income – is comprised primarily of the management fee income associated with tenant construction project reimbursements. After adoption of ASU 2014-09 we believe that we will account for the management fee associated with tenant construction project reimbursements using the percentage of completion method, which is the method we have used historically. Once the new guidance setting forth principles for the recognition, measurement, presentation and disclosure of leases (discussed below) goes into effect, we believe that the new revenue standard may apply to executory costs and other components of revenue due under leases that are deemed to be non-lease components, even when the revenue for such activities is not separately stipulated in the lease. In that case, then revenue from these items previously recognized on a straight-line basis under current lease guidance would be recognized under the new revenue guidance as the related services are delivered. As a result, while the total revenue recognized over time would not differ under the new guidance, the recognition pattern could be different. The Company is currently in the process of evaluating the significance of the difference in the recognition pattern that would result from this change. The Company is continuing to evaluate the disclosure requirements in the guidance and has not determined the impact on the footnote disclosures to its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for in the same manner as operating leases today. As of December 31, 2017, the Company had a sublease for office space in Washington D.C. expiring in June 2021 and a lease for office space in San Diego, CA expiring in April 2022. The remaining contractual payments under the Company’s lease and sublease for office space aggregate $1.9 million. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. As discussed in further detail above, in connection with the new revenue guidance, we believe that the new revenue standard may apply to executory costs and other components of revenue deemed to be non-lease components, even when the revenue for such activities is not separately stipulated in the lease. In that case, we would need to separate the lease components of revenue due under leases from the non-lease components. Under the new guidance, we would continue to recognize the lease components of lease revenue on a straight-line basis over our respective lease terms as we do under prior guidance. However, we would recognize the non-lease components under the new revenue guidance as the related services are delivered. As a result, while the total revenue recognized over time would not differ under the new guidance, the recognition pattern could be different. The Company is currently in the process of evaluating the significance of the difference in the recognition pattern that would result from this change. Additionally, ASU 2016-02 will require that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. Under ASU 2016-02, allocated payroll costs and other costs that are incurred regardless of whether the lease is obtained will no longer be capitalized as initial direct costs and instead will be expensed as incurred. ASU No. 2016-02 is effective for reporting periods beginning January 1, 2019, with modified retrospective application for each reporting period presented at the time of adoption. Early adoption is also permitted for this guidance. The Company is in the process of evaluating the impact of this new guidance. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), which provides classification guidance for certain cash receipts and cash payments including payment of debt extinguishment costs, settlement of zero-coupon de

At December 31, 2017 and 2016, the one-month LIBOR (“L”) was 1.56% and 0.77%, respectively. The current interest rate is not adjusted to include the amortization of deferred financing fees or debt issuance costs incurred in obtaining debt or any unamortized fair market value premiums. The spread over the applicable rate for the Company's senior unsecured revolving credit facility and senior unsecured term loan facility is based on the Company's consolidated leverage ratio, as defined in the respective loan agreements. (2) Available capacity of $300.2 million and $187.8 million at December 31, 2017 and 2016, respectively, with an accordion feature that provides additional capacity of up to $250.0 million, for a total facility size of not more than $650.0 million. (3) Our senior unsecured revolving credit facility has two six-month as-of-right extension options subject to certain conditions and the payment of an extension fee. (4) Entered into two interest rate swaps with an effective date of March 29, 2017 with an aggregate notional value of $100.0 million to effectively fix the interest rate at 3.17% annually, based on the Company’s consolidated leverage ratio, as defined in the senior unsecured term loan facility agreement. (5) Effective interest rates are as follows: CBP – Savannah 4.12%, ICE – Charleston 3.93%, MEPCOM – Jacksonville 3.89%, USFS II – Albuquerque 3.92%, DEA – Pleasanton 1.8%. The table below sets forth the costs included in interest expense related to the Company’s debt arrangements on the accompanying Consolidated Statements of Operations (dollars in thousands): For the year ended December 31, Costs Included in Interest Expense 2017 2016 2015 Amortization of deferred financing fees $ 1,181 $ 899 $ 756 2017 Activity On March 20, 2017 we fully drew $100.0 million on our senior unsecured term loan facility which we entered into on September 29, 2016. On May 25, 2017, the Operating Partnership issued $175 million of fixed rate, senior unsecured notes (the “Notes) in a private placement pursuant to a purchase agreement among the Operating Partnership, the Company and the purchasers of the Notes (the “Purchase Agreement”). The Notes are unconditionally guaranteed by the Company and various subsidiaries of the Operating Partnership (the “Subsidiary Guarantors”). Subject to the terms of the Purchase Agreement and the Notes, upon certain events of default, including, but not limited to, (i) a default in the payment of any principal, “make-whole” amount or interest under the Notes, and (ii) a default in the payment of certain other indebtedness of the Operating Partnership or of the Company or of the Subsidiary Guarantors, the principal and accrued and unpaid interest and the make-whole amount on the outstanding Notes will become due and payable at the option of the holders. The Purchase Agreement and the Notes also contain various covenants, including, among others, financial covenants with respect to debt service coverage, consolidated net worth, fixed charges and consolidated leverage and covenants relating to liens. If the Operating Partnership or the Company breaches any of these covenants, the principal and accrued and unpaid interest and the make-whole amount on the outstanding Notes will become due and payable at the option of the holders. The Operating Partnership may prepay at any time all, or from time to time any part of, the Notes, in the amount not less than 5% of the aggregate principal amount of the Notes then outstanding at (i) 100% of the principal amount so prepaid, together with accrued interest, and (ii) a make-whole amount that is calculated by discounting the value of the remaining scheduled interest payments that would otherwise be payable through the scheduled maturity date of the applicable Notes on the principal amount being prepaid. The Operating Partnership has the right to make tender offers and is required to make other prepayment offers under the terms set forth in the Purchase Agreement. On June 28, 2017, the Company, through a wholly-owned subsidiary of the Operating Partnership, entered into a $127.5 million mortgage loan secured by VA – Loma Linda. Our senior unsecured credit facility, senior unsecured term loan facility, senior unsecured notes, and mortgage notes are subject to ongoing compliance with a number of financial and other covenants. As of December 31, 2017, we were in compliance with the applicable financial covenants. 2016 Activity On September 29, 2016, we entered into a $100.0 million senior unsecured term loan facility (our “senior unsecured term loan facility”) with PNC Bank, National Association, as administrative agent, U.S. Bank National Association and SunTrust Bank, as syndication agents, PNC Capital Markets LLC, U.S. Bank National Association and SunTrust Robinson Humphrey, Inc., as joint lead arrangers and joint bookrunners. The Operating Partnership is the borrower under our senior unsecured term loan facility and we and certain of our subsidiaries that directly own certain of our properties are guarantors under the term loan facility. The senior unsecured term loan facility matures on September 29, 2023, has a 180-day delayed draw period, and is prepayable without penalty beginning in October 2018. Borrowings under our senior unsecured term loan facility will bear interest at floating rates equal to, at our option, either (1) a fluctuating rate equal to the sum of (a) the highest of (x) PNC Bank, National Association’s base rate, (y) the federal funds open rate plus 0.50% and (z) the daily Eurodollar rate plus 1.00% plus (b) a margin ranging from 0.7% to 1.35%, or (2) a Eurodollar rate equal to a periodic fixed rate equal to LIBOR plus, a margin ranging from 1.7% to 2.35%, in each case with a margin based on our leverage ratio. Based on our current leverage ratio, borrowings under our senior unsecured term loan facility will have an initial interest rate of LIBOR plus 170 basis points. We may prepay our senior unsecured term loan facility in whole or in part, subject to (i) customary costs, if any, of breaking LIBOR and, (ii) payment of a prepayment penalty equal to 2.0% of the principal balance being repaid during the first 12 months of our senior unsecured term loan facility and 1.0% of the principal balance being repaid during the following 12 months. On October 27, 2016, we entered into two forward-starting interest rate swaps with an effective date of March 29, 2017 and an aggregate notional value of $100.0 million to effectively fix the interest rate on future draw downs under our senior unsecured term loan facility. The forward swaps, which extend until the maturity of the term loan on September 29, 2023 effectively fix the interest rate under our senior unsecured term loan facility at 3.17% annually based on the company’s current leverage ratio. Our senior unsecured term loan facility also contains certain customary covenants, including but not limited to financial covenants that require us to maintain maximum ratios of consolidated total indebtedness, consolidated secured indebtedness and consolidated secured recourse indebtedness to total asset value, minimum consolidated tangible net worth and a minimum consolidated fixed charge ratio. As of December 31, 2016 we had not drawn funds under our senior unsecured term loan facility. Our senior unsecured credit facility and mortgage notes are subject to ongoing compliance with a number of financial and other covenants. As of December 31, 2016, we were in compliance with the applicable financial covenants. Fair Value of Debt As of December 31, 2017 and 2016, the carrying value of our senior unsecured revolving credit facility approximated fair value. In determining the fair value we considered the short term maturity, variable interest rate and credit spreads. We deem the fair value of our senior unsecured revolving credit facility as a Level 3 measurement. As of December 31, 2017, the carrying value of our senior unsecured term loan facility approximated fair value. In determining the fair value we considered the variable interest rate and credit spreads. We deem the fair value of our senior unsecured term loan facility as a Level 3 measurement. As of December 31, 2017, the fair value of our notes payable was determined by discounting future contractual principal and interest payments using prevailing market rates. We deem the fair value measurement of our notes payable instruments as a Level 3 measurement. At December 31, 2017, the fair value of our notes payable was $177.5 million. As of December 31, 2017 and 2016, the fair value of our mortgage debt was determined by discounting future contractual principal and interest payments using prevailing market rates. We deem the fair value measurement of our mortgage debt instruments as a Level 3 measurement. At December 31, 2017 and 2016, the fair value of our mortgage debt was $203.1 million and $79.4 million, respectively. Aggregate Debt Maturities The Company’s aggregate debt maturities based on outstanding principal as of December 31, 2017 are as follows (dollars in thousands): Total 2018 $ 3,100 2019 102,979 2020 3,395 2021 4,054 2022 5,109 Thereafter 461,018 579,655 Unamortized premium/discount & deferred financing (3,761 ) $ 575,894

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	5. Derivatives and Hedging Activities As of December 31, 2017, the Company had two outstanding forward-starting interest rate swaps with an aggregate notional value of $100.0 million that were designated as cash flow hedges. The forward swaps had an effective date of March 29, 2017 and extend until the maturity of the term loan on September 29, 2023. The forward swaps will effectively fix the interest rate under our senior unsecured term loan facility at 3.17% annually based on the company’s current leverage ratio. Cash Flow Hedges of Interest Rate Risk As of December 31, 2017 and 2016, our forward swaps were classified as an asset on our consolidated balance sheet at $ 4.0 million and $3.8 million, respectively. The effective portion of changes in the fair value of derivatives designated and qualified as cash flow hedges is recorded in accumulated other comprehensive income and will be reclassified to interest expense in the period that the hedged forecasted transactions affect earnings on the Company’s variable rate debt. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings into interest expense. For the year ended December 31, 2017 the amount of unrealized gain recognized in accumulated other comprehensive income on interest rate swaps was $0.1 million and $0.2 million was reclassified from accumulated other comprehensive income on interest rate swaps as an increase to interest expense. For the year ended December 31, 2016 the amount of unrealized gain recognized in accumulated other comprehensive income on interest rate swaps was $3.8 million. Additionally, during the years ended December 31, 2017 and 2016, there was no ineffectiveness. The Company estimates that $0.4 million will be reclassified from accumulated other comprehensive income as a decrease to interest expense over the next 12 months. Credit-risk-related Contingent Features The Company has agreements with each of its derivative counterparties that contain a provision where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company's default on the indebtedness. As of December 31, 2017 and 2016, the Company did not have any derivatives in a net liability position.

Fair Value Disclosures [Abstract]
Fair Value Measurements	6. Fair Value Measurements Accounting standards define fair value as the exit price, or the amount that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standards also establish a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of us. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The hierarchy of these inputs is broken down into three levels: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Categorization within the valuation hierarchy is based upon the lowest level of input that is most significant to the fair value measurement. Fair Value of Interest Rate Swaps The fair values of our interest rate swaps are determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities in such interest rates. While the Company determined that that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. The Company has determined that the significance of the impact of the credit valuation adjustments made to its derivative contracts, which determination was based on the fair value of each individual contract, was not significant to the overall valuation. As a result, all of the Company’s derivatives held as of December 31, 2017 and 2016 were classified as Level 2 of the fair value hierarchy. The carrying values of cash and cash equivalents, restricted cash, accounts receivable, other assets and accounts payable and accrued expenses are reasonable estimates of fair values because of the short maturities of these instruments. For our disclosure of debt fair values in Note 4, we estimated the fair value of our unsecured senior revolving credit facility based on the short term maturity, variable interest rates and credit spreads (categorized within Level 3 of the fair value hierarchy), estimated the fair value of our senior unsecured term loan facility based on the variable interest rate and credit spreads (categorized within Level 3 of the fair value hierarchy) and estimated the fair value of our other debt based on the discounted estimated future cash payments to be made on such debt (categorized within Level 3 of the fair value hierarchy); the discount rates used approximate current market rates for loans, or groups of loans, with similar maturities and credit quality, and the estimated future payments included scheduled principal and interest payments. Fair value estimates are made as of a specific point in time, are subjective in nature and involve uncertainties and matters of significant judgement. Settlement at such fair value amounts may not be possible and may not be prudent management decision. The following sets forth the Company’s financial instruments that are accounted for at fair value on a recurring basis as of December 31, 2017 and December 31, 2016.

Equity [Abstract]
Equity	7. Equity On October 16, 2014, the Company issued 1,000 shares to its sole stockholder, Darrell Crate, for $1,000, which we repurchased upon the IPO. On February 11, 2015, we completed an initial public offering of 13.8 million shares of our common stock at a price to the public of $15.00 per share, including 1.8 million shares sold in connection with the full exercise of the option to purchase additional shares granted to the underwriters, resulting in gross proceeds of $207.0 million. In connection with the IPO, we engaged in a series of formation transactions by which we acquired 15 properties previously owned by the Easterly Funds and the ownership interests in the management entities in exchange for 9,771,120 common units and 3,308,000 shares of common stock. Additionally, in connection with the IPO, Western Devcon contributed its interest in 14 properties to the Operating Partnership in an exchange for 5,759,819 common units. On October 21, 2015, Western Devcon contributed its interest an additional property, DEA – Pleasanton, to the Operating Partnership in exchange for 12,500 common units. Concurrent with the IPO, the Company sold an aggregate of 7,033,712 shares of its common stock to the Easterly Funds in a private placement at a price per share of $15.00 without payment of any underwriting fees, discounts or commissions. Prior to the completion of the IPO, our board of directors adopted, and our sole stockholder approved, our 2015 Equity Incentive Plan, under which we may grant cash and equity incentive awards to our executive officers, non-employee directors and eligible employees in order to attract, motivate and retain the talent for which we compete. The 2015 Equity Incentive Plan is administered by the compensation committee of our board of directors and permits us to make grants of options, stock appreciation rights, restricted stock units, restricted stock, dividend equivalent rights, cash-based awards, performance-based awards and other equity-based awards, including LTIP units, or any combination of the foregoing. Grant awards of restricted stock, restricted stock units, performance shares or cash-based awards under the 2015 Equity Incentive Plan are intended to qualify as “performance based compensation” under Section 162(m) of the Code. Those awards would only vest or become payable upon the attainment of performance goals that are established by our compensation committee and related to established performance criteria. From and after the time that we become subject to Section 162(m) of the Code, the maximum award that is intended to qualify as “performance-based compensation” under Section 162(m) of the Code that may be made to any one employee during any one calendar year period is 2,273,959 shares of our common stock with respect to stock-based award and $5.0 million with respect to a cash based award. The shares issued under the 2015 Equity Incentive Plan are authorized but unissued shares or shares that we reacquire. The shares of our common stock underlying any awards that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, reacquired by us prior to vesting, satisfied without any issuance of stock, expire or are otherwise terminated (other than by exercise) under the 2015 Equity Incentive Plan are added back to the shares available for issuance under the 2015 Equity Incentive Plan. At the Company’s 2017 annual meeting of stockholders held on May 9, 2017, the Company’s stockholders approved an amendment to the 2015 Equity Incentive Plan to increase the aggregate number of shares authorized for issuance under the 2015 Equity Incentive Plan by 3,000,000 shares to 5,273,959 shares of our common stock. In connection with the Company’s 2017 annual meeting of stockholders, we issued an aggregate of 15,220 shares of restricted common stock to our non-employee directors, which will vest upon the earlier of the anniversary of the date of grant or the Company’s 2018 annual meeting of stockholders. The Company granted 891,000 LTIP units on May 6, 2015 and 40,000 LTIP units on February 26, 2016 to members of management as long-term incentive compensation under the 2015 Equity Incentive Plan, subject to the Company achieving certain absolute and relative total shareholder returns through the performance period, which ended on December 31, 2017. Based on the Company’s absolute and relative total shareholder return performance through the end of the performance period, the compensation committee determined that an aggregate of 2,079,297 LTIP units were earned. Under the terms of the awards, earned awards vested 50% on February 15, 2018 with the remaining 50% vesting on February 6, 2019, subject to the grantee’s continued employment. Vesting will be accelerated in the event of a change in control, termination of employment by the Company without cause, or termination of employment by the award recipient for good reason, death, disability or retirement. Conditioned upon minimum allocations to the capital accounts of the LTIP units for federal income tax purposes, each vested LTIP unit may be converted, at the election of the holder, into a common unit and each common unit acquired upon conversion of an LTIP unit may be presented for redemption, at the election of the holder, for cash equal to the fair market value of a share of our common stock, except that the Company may, at its election, acquire each common unit so presented for one share of our common stock. A summary of our non-vested common share awards at December 31, 2017, 2016 and 2015 is as follows: Restricted Shares Restricted Shares Weighted average grant date fair value LTIP Units LTIP Units Weighted average grant date fair value Outstanding December 31, 2014 — $ — — $ — Vested — — — — Granted 26,667 15.00 891,000 8.67 Forfeited — — — — Outstanding, December 31, 2015 26,667 $ 15.00 891,000 $ 8.67 Vested (26,667 ) $ 15.00 — $ — Granted 16,128 18.60 40,000 14.15 Forfeited — — (5,000 ) 8.67 Outstanding, December 31, 2016 16,128 $ 18.60 926,000 $ 8.91 Vested (16,128 ) $ 18.60 — $ — Granted 17,912 19.72 — — Forfeited — — — — Outstanding, December 31, 2017 17,912 $ 19.72 926,000 $ 8.91 We recognized $3.0 million, $2.9 million and $1.9 million in compensation expense, related to the restricted common stock and the LTIP unit awards, for the years ended December 31, 2017, 2016 and 2015, respectively. As of December 31, 2017 unrecognized compensation expense for both awards was $1.6 million, which will be amortized over the vesting period. We valued our non-vested restricted share awards at the grant date fair value, which was the market price of our common stock as of the applicable grant date. For the LTIP unit awards granted, we used a Monte Carlo Simulation (risk-neutral approach) to determine the number of shares that may be issued pursuant to the award. For LTIP units granted in 2016 we utilized a risk-free rate of 0.7%, derived from the Treasury note yield as of the grant date. Since the Company has a limited amount of operating history, the expected volatility assumption of 20.0% was derived from the observed historical volatility of the common stock prices of a select group of peer companies within the REIT industry. Based on the selected dividend yields of guideline companies and expected dividend levels, we utilized an expected dividend yield of 5.5%. For LTIP units granted in 2015 we utilized a risk-free rate of 0.9%, derived from the Treasury note yield as of the grant date. Since the Company has a limited amount of operating history, the expected volatility assumption of 18.3% was derived from the observed historical volatility of the common stock prices of a select group of peer companies within the REIT industry. Based on the selected dividend yields of guideline companies and expected dividend levels, we utilized an expected dividend yield of 5.5%. No additional shares of common stock or options were issued under the 2015 Equity Incentive Plan as of December 31, 2017. On June 7, 2016, we completed an underwritten public offering of an aggregate of 6,219,045 shares of common stock, consisting of 4,719,045 shares sold by us to the underwriters and 1,500,000 shares offered on a forward basis in connection with certain forward sales agreements. The gross proceeds from the offering of 4,719,045 shares sold by us to the underwriters was $84.9 million before deducting underwriting discounts, commissions and estimated offering expenses. On November 29, 2016, the Company’s physically settled the forward sales agreements by issuing an aggregate of 1,500,000 shares of common stock in exchange for approximately $25.1 million. The Company accounted for the forward share agreements as equity. On March 27, 2017, we completed an underwritten public offering of an aggregate of 4,945,000 shares of common stock, including 645,000 shares sold pursuant the underwriters’ exercise in full of their option to purchase additional shares. The shares were offered on a forward basis in connection with certain forward sales agreements entered into with certain financial institutions, acting as forward purchasers. Pursuant to the forward sales agreements, the forward purchasers borrowed and the forward sellers, acting as agents for the forward purchasers, sold an aggregate of 4,945,000 shares in the public offering. On September 11, 2017, the Company physically settled the forward sales agreements by issuing an aggregate of 4,945,000 shares of common stock in exchange for approximately $92.7 million. The Company accounted for the forward share agreements as equity.

After the end of the performance period, the number of LTIP units, both vested and unvested, that LTIP award recipients have earned, if any, are entitled to receive dividends in an amount per LTIP unit equal to dividends, both regular and special, payable per common unit of our operating partnership. On March 3, 2017, we entered into separate equity distribution agreements with each of Citigroup Global Markets Inc., BTIG, LLC, Jefferies LLC, Raymond James & Associates, Inc., RBC Capital Markets, LLC and SunTrust Robinson Humphrey, Inc. (collectively, the “managers”), pursuant to which we may issue and sell the shares of our common stock having an aggregate offering price of up to $100.0 million from time to time through the managers, acting as sales agents and/or principals (the “ATM Program”).

Earnings Per Share [Abstract]
Earnings Per Share	8. Earnings Per Share Basic earnings or loss per share of common stock (“EPS”) is calculated by dividing net income or loss attributable to common stockholders by the weighted average shares of common stock outstanding for the periods presented. Diluted EPS is computed after adjusting the basic EPS computation for the effect of dilutive common equivalent shares outstanding during the periods presented. Unvested restricted shares and LTIP units are considered participating securities which require the use of the two-class method for the computation of basic and diluted earnings per share. The following table sets forth the computation of the Company’s basic and diluted earnings per share of common stock for the years ended December 31, 2017, 2016 and 2015 (amounts in thousands, except per share amounts): For the years ended December 31, 2017 2016 2015 Numerator Net income (loss) $ 5,389 $ 5,497 $ (5,371 ) Less: Non-controlling interest in Operating Partnership (941 ) (1,534 ) 4,087 Net income (loss) available to Easterly Government Properties, Inc. 4,448 3,963 (1,284 ) Less: Dividends on participating securities (110 ) (102 ) (63 ) Net income (loss) available to common stockholders $ 4,338 $ 3,861 $ (1,347 ) Denominator for basic EPS 39,607,740 30,645,279 21,430,016 Dilutive effect of share-based compensation awards 11,384 13,691 — Dilutive effect of LTIP units 1,944,416 1,713,568 — Denominator for basic and diluted EPS 41,563,540 32,372,538 21,430,016 Basic EPS $ 0.11 $ 0.13 $ (0.06 ) Diluted EPS $ 0.10 $ 0.12 $ (0.06 ) During the year ended December 31, 2015, there were 26,667 and 891,000 shares of unvested restricted shares and LTIP units, respectively, on a weighted average basis that could potentially dilute basic EPS in the future. These shares were not included in the computation of diluted EPS because to do so would have been antidilutive.

Concentrations Risk	11. Concentrations Risk Concentrations of credit risk arise for the Company when multiple tenants of the Company are engaged in similar business activities, are located in the same geographic region or have similar economic features that impact in a similar manner their ability to meet contractual obligations, including those to the Company. The Company regularly monitors its tenant base to assess potential concentrations of credit risk. As stated in Note 1 above, the Company leases commercial space to the U.S. Government through the GSA or other federal agencies or nongovernmental tenants. At December 31, 2017, the GSA and other federal agency accounted for approximately 98.7% of rental income and non-governmental tenants accounted for the remaining approximately 1.3%. At December 31, 2016, the GSA and other federal agency accounted for approximately 96.8% of rental income and non-governmental tenants accounted for the remaining approximately 3.2%. At December 31, 2017, fourteen of our 46 operating properties were located in California, accounting for approximately 25.8% of our total rentable square feet and approximately 33.3% of our total annualized lease income. At December 31, 2016, thirteen of our 43 operating properties were located in California, accounting for approximately 20.0% of our total rentable square feet and approximately 26.8% of our total annualized lease income. To the extent that weak economic or real estate conditions or natural disasters affect California, our business, financial condition and results of operations could be negatively impacted.

Revision of Previously Reported Consolidated Financial Statements	Revision of Previously Reported Consolidated Financial Statements In connection with the preparation of the Company's consolidated financial statements for the year ended December 31, 2017, the Company identified an error in the estimated useful life utilized to amortize certain assets associated with three properties contributed at the time of the initial public offering in the first quarter of 2015. As a result of the error, Depreciation and amortization expense had been overstated and thereby Real estate properties, net, Intangible assets, net and Equity were understated. The Company concluded that the amounts are not material to any of its previously issued consolidated financial statements. However, to maintain proper comparability between our financial statements we have elected to revise prior periods. Accordingly, the Company has revised these balances in the accompanying consolidated financial statements as of December 31, 2016 and for the years ended December 31, 2016 and December 31, 2015 as outlined below. The effects of this revision to the consolidated financial statements are as follows (in thousands, except for per share data).

Use of Estimates	Use of Estimates The preparation of the consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the balance sheet and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Real Estate Properties	Real Estate Properties Real estate properties comprise all tangible assets we hold for rent or development. Real property is recognized at cost less accumulated depreciation. Acquisition costs related to business combinations, including third party transaction and direct internal costs are expensed as incurred. Third party costs related to asset acquisitions are capitalized. Development, re-development and certain costs directly related to the improvement of real properties are capitalized. Maintenance and repair expenses are charged to expense as incurred. When we acquire properties, we allocate the purchase price to numerous tangible and intangible components. Our process for determining the allocation to these components requires many estimates and assumptions, including the following: (1) determination of market rental rates; (2) estimation of leasing and tenant improvement costs associated with the remaining term of acquired leases; (3) assumptions used in determining the in-place lease and if-vacant value including the rental rates, period of time that it would take to lease vacant space and estimated tenant improvement and leasing costs; (4) renewal probabilities; and (5) allocation of the if-vacant value between land and building. A change in any of the above key assumptions can materially change not only the presentation of acquired properties in our consolidated financial statements but also our reported results of operations. The allocation to different components affects the following: • the amount of the purchase price allocated among different categories of assets and liabilities on our consolidated balance sheets; and the amount of costs assigned to individual properties in multiple property acquisitions; • where the amortization of the components appear over time in our consolidated statements of operations. Allocations to above- and below-market leases are amortized into rental revenue, whereas allocations to most of the other tangible and intangible assets are amortized into depreciation and amortization expense. As a REIT, this is important to us since much of the investment community evaluates our operating performance using non-GAAP measures such as Funds From Operations, the computation of which includes rental revenue but does not include depreciation and amortization expense; and • the timing over which the items are recognized as revenue or expense in our consolidated statements of operations. For example, for allocations to the as-if vacant value, the land portion is not depreciated and the building portion is depreciated over a longer period of time than the other components (generally 40 years). Allocations to above- and below-market leases and in-place lease value are amortized over significantly shorter timeframes, and if individual tenants’ leases are terminated early, any unamortized amounts remaining associated with those tenants are written off upon termination. These differences in timing can materially affect our reported results of operations. Tenant improvements are capitalized in real property when we own the improvement. When we are required to provide improvements under the terms of a lease, we need to determine whether the improvements constitute landlord assets or tenant assets. If the improvements are considered landlord assets, we capitalize the cost of the improvements and recognize depreciation expense associated with such improvements over the shorter of the useful life of the assets or the term of the lease and recognize any payments from the tenant as rental revenue over the term of the lease. If the improvements are considered tenant assets, we defer the cost of improvements funded by us as a lease incentive asset and amortize it as a reduction of rental revenue over the term of the lease. Our determination of whether improvements are landlord assets or tenant assets also may affect when we commence revenue recognition in connection with a lease. In determining whether improvements constitute landlord or tenant assets, we consider numerous factors that may require subjective or complex judgments, including: whether the improvements are unique to the tenant or reusable by other tenants; whether the tenant is permitted to alter or remove the improvements without our consent or without compensating us for any lost fair value; whether the ownership of the improvements remains with us or remains with the tenant at the end of the lease term; and whether the economic substance of the lease terms is properly reflected. We capitalize pre-development costs incurred in pursuit of new development opportunities for which we currently believe future development is probable. Additionally, we capitalize interest expense, real estate taxes and direct and indirect project costs (including related compensation and other indirect costs) associated with properties, or portions thereof, undergoing construction, development and redevelopment activities. In capitalizing interest expense, if there is a specific borrowing for the property undergoing construction, development and redevelopment activities, we apply the interest rate of that borrowing to the average accumulated expenditures that do not exceed such borrowing; for the portion of expenditures exceeding any such specific borrowing, we apply our weighted average interest rate on other borrowings to the expenditures. We continue to capitalize costs while construction, development or redevelopment activities are underway until the building is substantially complete and ready for its intended use. Depreciation of an asset begins when it is available for use and is calculated using the straight-line method over the estimated useful lives. Each period, depreciation is charged to expense and credited to the related accumulated depreciation account. A used asset acquired is depreciated over its estimated remaining useful life, not to exceed the life of a new asset. Range of useful lives for depreciable assets are as follows: Category Term Buildings 40 years Building improvements 5 - 40 years Tenant improvements Shorter of remaining life of the lease or useful life Furniture and equipment 3 - 7 years We regularly evaluate whether events or changes in circumstances have occurred that could indicate an impairment in the value of long lived assets. If there is an indication that the carrying value of an asset is not recoverable, we estimate the projected undiscounted cash flows to determine if an impairment loss should be recognized. We determine the amount of any impairment loss by comparing the historical carrying value to estimated fair value. We estimate fair value through an evaluation of recent financial performance and projected discounted cash flows using standard industry valuation techniques. In addition to consideration of impairment upon the events or changes in circumstances described above, we regularly evaluate the remaining lives of our long lived assets. If we change our estimate of the remaining lives, we allocate the carrying value of the affected assets over their revised remaining lives.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include all cash and liquid investments that mature three months or less from when they are purchased. Cash equivalents are reported at cost, which approximates fair value. We maintain our cash in bank accounts in amounts that may exceed federally insured limits at times. We have not experienced any losses in these accounts and believe that we are not exposed to significant credit risk because our accounts are deposited with major financial institutions.
Restricted Cash	Restricted Cash Restricted cash consists of amounts escrowed for future real estate taxes, insurance, capital expenditures and debt service, as required by certain of our mortgage debt agreements.
Rent Receivable and Accounts Receivable	Rent Receivable and Accounts Receivable Rent receivable and Accounts receivable on the accompanying Consolidated Balance Sheets includes accrued rental income and other tenant accounts receivable, respectively. The Company accrues rental and other tenant income earned, but not yet receivable, in accordance with GAAP.
Deferred Costs	Deferred Costs Deferred financing fees and debt issuance costs include costs incurred in obtaining debt that are capitalized and are presented as a direct deduction from the carry amount of the associated debt liability that is not a line-of-credit arrangement on the accompanying Consolidated Balance Sheets. Deferred financing fees and debt issuance costs related to line-of-credit arrangements are presented as an asset in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. The deferred financing fees and debt issuance costs are amortized through interest expense over the life of the respective loans on a basis which approximates the effective interest method. Any unamortized amounts upon early repayment of debt are written off in the period of repayment as a loss on extinguishment of debt. Fully amortized deferred financing fees and debt issuance costs are removed from the books upon maturity of the underlying debt. Deferred offering costs include certain legal, accounting and other third party fees that are directly associated with in-process equity financings until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction to capital. Should the equity financing no longer be considered probable of being consummated, the deferred offering costs would be expensed immediately as a charge to corporate general and administrative expenses in the accompanying Consolidated Statement of Operations. Deferred leasing commissions include commissions, compensation costs of leasing personnel, and other direct and incremental costs incurred to obtain new tenant leases as well as to renew existing tenant leases, and are presented in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. Leasing commission are capitalized and amortized over the terms of the related leases upon lease commencement using the straight-line method. If a lease terminates prior to the expiration of its initial term, any unamortized costs related to the lease are accelerated into amortization expense. Changes in leasing commissions are presented in the cash flows from operating activities section of the accompanying Consolidated Statements of Cash Flows.
Interest Rate Swaps	Interest Rate Swaps The Company’s primary objective in using interest rate derivatives are to add stability to interest expense and to manage exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable- rate amounts from a counterparty in exchange for our making fixed- rate payments over the life of the agreements without exchange of the underlying notional amount. Derivatives are used to hedge the cash flows associated with interest rates on existing debt as well as future debt. We recognize derivatives as assets or liabilities on the balance sheet at fair value. We defer the effective portion of changes in fair value of the designated cash flow hedges to accumulated other comprehensive income (“AOCI”) or loss (“AOCL”) and reclassify such deferrals to interest expense as interest expense is recognized on the hedged forecasted transitions. We recognize the ineffective portion of the change in fair value of interest rate derivatives directly in interest expense. When an interest rate swap designated as a cash flow hedge no longer qualified for hedge accounting, we recognize changes in fair value of the hedge previously deferred to AOCI or AOCL, along with any changes in fair value occurring thereafter, through earnings. We do not use interest rate derivatives for trading or speculative purposes. We manage counterparty risk by only entering into contracts with major financial institutions based upon their credit ratings and other risk factors. We use standard market conventions and techniques such as discounted cash flow analysis, option pricing models, replacement cost and termination cost in computing the fair value of derivatives at each balance sheet date. The Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Please refer to Note 5 for more information pertaining to interest rate derivatives.
Non-controlling Interests	Non-Controlling Interests Non-controlling interests relate to the common units of the Operating Partnership not owned by the Company. Unitholders receive a distribution per unit equivalent to the dividend per share of the Company’s common stock. Pursuant to the consolidation accounting standard with respect to the accounting and reporting for non-controlling interest changes and changes in ownership interest of a subsidiary, changes in parent’s ownership interest when the parent retains controlling interest in the subsidiary should be accounted for as equity transactions. The carrying amount of the non-controlling interest shall be adjusted to reflect the change in its ownership interest in the subsidiary, with the offset to equity attributable to the Company. Non-Controlling Interest The Company addresses the accounting and reporting standards for ownership interests in subsidiaries held by parties other than the parent, the amount of consolidated capital resulting from operations attributable to the parent and to the non-controlling interest, the changes in a parent’s ownership interest, and the valuation of retained non-controlling equity investments when a subsidiary is deconsolidated in accordance with ASC 810 “Consolidation”. Prior to the IPO, all of the partners invested in the Easterly Funds represented a non-controlling interest. In addition, prior to the IPO, a third-party member had invested in Federal Properties, GP, LLC, an entity included within the Predecessor, which also represented a non-controlling interest.
Revenue Recognition	Revenue Recognition Rental income includes base rents paid by each tenant in accordance with its lease agreement conditions. We recognize rental income on a straight-line basis over the lease term of the respective leases. For acquisitions of existing buildings, we recognize rental income from leases already in place coincident with the date of property closing. Lease incentives are recorded as a deferred asset and amortized as a reduction of revenue on a straight-line basis over the respective lease term. Above- and below-market leases are amortized into rental income over the terms of the respective leases. Tenant reimbursement income (scheduled rent increases based on increases in real estate taxes, operating expenses and utility usage, projects and other reimbursements) is recognized by us in the consolidated statements of operations once services are rendered, fees are determinable and collectability is assured. We recognize revenue from tenant construction projects using the percentage of completion method when the revenue and costs for such projects can be estimated with reasonable accuracy; when these criteria do not apply to a project, we recognize revenue from that project using the completed contract method. Under the percentage of completion method, we recognize a percentage of the total estimated revenue on a project based on the cost of services provided on the project as of a point in time relative to the total estimated costs on the project. For the year ended December 31, 2017, we incurred $3.8 million in expenses associated with projects and other services that were fully reimbursed by our tenants and earned $0.6 million in associated income. For the year ended December 31, 2016, we incurred $3.8 million in expenses associated with projects and other services that were fully reimbursed by our tenants and earned $0.5 million in associated income. For the year ended December 31, 2015, we incurred $1.2 million in expenses associated with projects and other services that were fully reimbursed by our tenants and $0.2 million in associated income. Fully reimbursed income was included within “Tenant reimbursements” and associated expenses were included in “Property operating” expenses. Income on these projects was included in “Other income”.
Income Taxes	Income Taxes We believe that we have operated and have been organized in conformity with the requirements for qualification and taxation as a REIT for U.S. federal income tax purposes commencing with our taxable year ended December 31, 2015. So long as we qualify as a REIT, we generally will not be subject to U.S. federal income tax on our net income that we distribute to our stockholders. To maintain our qualification as a REIT, we are required under the Code to distribute at least 90% of our REIT taxable income (without regard to the deduction for dividends paid and excluding net capital gains) to our stockholders and meet certain other requirements. If we fail to qualify as a REIT in any taxable year, we will be subject to U.S. federal income tax on our taxable income at regular corporate rates. Even if we qualify as a REIT, we will be subject to certain U.S. federal, state and local taxes on our income and property, and on taxable income that we do not distribute to our stockholders. In addition, we may provide services that are not customarily provided by a landlord, hold properties for sale and engage in other activities (such as a management business) through Taxable REIT Subsidiaries (“TRSs”) and the income of those subsidiaries will be subject to U.S. federal income tax at regular corporate rates. For the years ended December 31, 2017, 2016 and 2015, we did not incur any material tax liability associated with any of the above. We do not anticipate any potential expense related to uncertain tax positions as we closely monitor our REIT compliance, do not have any prohibited transactions related to property sales, and neither the states in which we operate nor our foreign investors subject us to withholding tax requirements. The following table reconciles GAAP net income to taxable income: For the years ended December 31, 2017 2016 2015 Net income (loss) $ 5,389 $ 5,497 $ (5,371 ) Book depreciation and amortization 54,782 45,797 32,809 Above/Below market lease amortization (8,517 ) (7,153 ) (4,866 ) Straight-line rent and other non-cash adjustments (2,776 ) (108 ) (220 ) Book/Tax differences on offering and acquisition costs at IPO — — 2,928 Book/Tax differences on unearned rent 16 (37 ) 2,138 Book/Tax differences on stock based compensation 2,663 2,780 1,867 Book/Tax differences on post IPO property acquisition costs — 620 856 Other book/tax differences, net 383 901 (214 ) Tax depreciation (25,552 ) (20,622 ) (16,451 ) Loss attributable to non-controlling interest (5,180 ) (8,474 ) (7,956 ) Loss attributable to predecessor — — 5,581 Taxable income subject to distribution requirements $ 21,208 (1) $ 19,201 (2) $ 11,101 (3) (1) The Company’s distributions are characterized as 47.24% ordinary taxable dividend and 52.76% return of capital. (2) The Company’s distributions are characterized as 59.32% ordinary taxable dividend and 40.68% return of capital. (3) The Company’s distributions are characterized as 85.06% ordinary taxable dividend and 14.94% return of capital.
Stock Based Compensation	Stock Based Compensation The Company grants equity-based compensation awards to its officers, employees and non-employee directors in the form of restricted shares of common stock and long-term incentive plan units in the Operating Partnership (“LTIP units”). See Note 7 (Equity) for further discussion of restricted shares of common stock and LTIP units. The restricted shares of common stock and LTIP units issued to officers, employees, and non-employee directors vest over a period of time as determined by our board of directors at the date of grant. The Company recognizes compensation expense for non-vested restricted shares of common stock and LTIP units granted to officers, employees and non-employee directors on a straight-line basis over the requisite service and/or performance period based upon the fair market value of the shares on the date of grant, as adjusted for forfeitures.
Earnings Per Share of Common Stock Amount	Earnings Per Share of Common Stock Amount Basic earnings per share is calculated by dividing net income available to Easterly Government Properties Inc. by the weighted-average number of shares of common stock outstanding during the period, excluding the weighted average number of unvested restricted shares. Diluted earnings per share is calculated by dividing net income by the weighted-average number of shares of common stock outstanding during the period plus other potentially dilutive securities such as unvested restricted shares that would be issued in the event that common units of the Operating Partnership are redeemed for shares of common stock of the Company. Unvested restricted shares and LTIP units are considered participating securities which require the use of the two-class method for the computation of basic and diluted earnings per share.
Segments	Segments The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. All revenue has been generated and all tangible assets are held in the United States.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements On January 1, 2017, the Company adopted ASU 2017-01, Business Combinations (Topic 805), which clarifies the framework for determining whether an integrated set of assets and activities meets the definition of a business. The revised framework establishes a screen for determining whether an integrated set of assets and activities is a business and narrows the definition of a business, which is expected to result in fewer transactions being accounted for as business combinations. Acquisitions of integrated sets of assets and activities that do not meet the definition of a business are accounted for as asset acquisitions. As a result, the Company believes most of our future acquisitions of operating properties will qualify as asset acquisitions and third-party transaction costs associated with these acquisitions will be capitalized while internal acquisition costs will continue to be expensed. On January 1, 2017, the Company adopted ASU No. 2016-09, Compensation – Stock Compensation, which identifies areas for simplification involving several aspects of accounting for share-based payment transactions. The new guidance allows for entities to make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. In addition, the guidance allows employers to withhold shares to satisfy minimum statutory tax withholding requirements up to the employees’ maximum individual tax rate without causing the award to be classified as a liability. The guidance also stipulates that cash paid by an employer to a taxing authority when directly withholding shares for tax-withholding purposes should be classified as a financing activity on the statement of cash flows. The implementation of this update did not have an impact on our consolidated financial statements.
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers and will replace most existing revenue recognition guidance when it becomes effective. This amendment applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC (“Accounting Standards Codification”). In July 2015, the FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 by one year to annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The Company will adopt ASU 2014-09 using the modified retrospective approach. The Company has evaluated the impact of this new guidance and notes the adoption of this guidance will not be material to its financial results. Additional information about the Company’s revenue streams and other considerations are summarized below. Rental income from real property is derived from rental agreements, whereby 44 of the Company’s operating properties are leased primarily to the U.S. Government and two of the Company’s operating properties are entirely leased to private tenants. Rental income from real property is specifically excluded from ASU 2014-09. Tenant reimbursements – is comprised of tenant reimbursements for real estate taxes, and certain other expenses, as well as tenant construction project reimbursements that consist primarily of subcontracted costs that are reimbursed to us by the tenant. Reimbursements from real estate taxes and certain other expenses are not included within the scope of ASU 2014-09. After adoption of ASU 2014-09, we believe that we will account for tenant construction project reimbursement arrangements using the percentage of completion method, which is the method we have used historically. Other income – is comprised primarily of the management fee income associated with tenant construction project reimbursements. After adoption of ASU 2014-09 we believe that we will account for the management fee associated with tenant construction project reimbursements using the percentage of completion method, which is the method we have used historically. Once the new guidance setting forth principles for the recognition, measurement, presentation and disclosure of leases (discussed below) goes into effect, we believe that the new revenue standard may apply to executory costs and other components of revenue due under leases that are deemed to be non-lease components, even when the revenue for such activities is not separately stipulated in the lease. In that case, then revenue from these items previously recognized on a straight-line basis under current lease guidance would be recognized under the new revenue guidance as the related services are delivered. As a result, while the total revenue recognized over time would not differ under the new guidance, the recognition pattern could be different. The Company is currently in the process of evaluating the significance of the difference in the recognition pattern that would result from this change. The Company is continuing to evaluate the disclosure requirements in the guidance and has not determined the impact on the footnote disclosures to its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for in the same manner as operating leases today. As of December 31, 2017, the Company had a sublease for office space in Washington D.C. expiring in June 2021 and a lease for office space in San Diego, CA expiring in April 2022. The remaining contractual payments under the Company’s lease and sublease for office space aggregate $1.9 million. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. As discussed in further detail above, in connection with the new revenue guidance, we believe that the new revenue standard may apply to executory costs and other components of revenue deemed to be non-lease components, even when the revenue for such activities is not separately stipulated in the lease. In that case, we would need to separate the lease components of revenue due under leases from the non-lease components. Under the new guidance, we would continue to recognize the lease components of lease revenue on a straight-line basis over our respective lease terms as we do under prior guidance. However, we would recognize the non-lease components under the new revenue guidance as the related services are delivered. As a result, while the total revenue recognized over time would not differ under the new guidance, the recognition pattern could be different. The Company is currently in the process of evaluating the significance of the difference in the recognition pattern that would result from this change. Additionally, ASU 2016-02 will require that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. Under ASU 2016-02, allocated payroll costs and other costs that are incurred regardless of whether the lease is obtained will no longer be capitalized as initial direct costs and instead will be expensed as incurred. ASU No. 2016-02 is effective for reporting periods beginning January 1, 2019, with modified retrospective application for each reporting period presented at the time of adoption. Early adoption is also permitted for this guidance. The Company is in the process of evaluating the impact of this new guidance. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), which provides classification guidance for certain cash receipts and cash payments including payment of debt extinguishment costs, settlement of zero-coupon debt instruments, insurance claim payments and distributions from equity method investees. The Company will adopt the standard effective January 1, 2018 and the implementation of this update will not have a material impact on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230), which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. This standard is effective for fiscal years beginning after December 15, 2017 and interim periods within those years, with early adoption permitted, and should be applied using a retrospective transition method to each period presented. Upon the adoption of ASU 2016-18, the Company will reconcile both cash and cash equivalents and restricted cash in the accompanying Statements of Cash Flows, whereas under the current guidance the Company explains the changes during the period for cash and cash equivalents only. The Company will adopt the standard effective January 1, 2018. In February 2017, the FASB issued ASU No. 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 ASU clarifies the scope and accounting of a financial asset that meets the definition of an “in-substance nonfinancial asset” and defines the term “in-substance nonfinancial asset.” This ASU also adds guidance for partial sales of nonfinancial assets. The Company will adopt the standard effective January 1, 2018 using the modified retrospective method and the implementation of this update will not have a material impact on our consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of either adopting the new standard early using a modified retrospective transition method in any interim period after issuance of the update, or alternatively adopting the new standard for fiscal years beginning after December 15, 2018. This adoption method may require the Company to recognize the cumulative effect of initially applying the ASU as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. While the Company continues to assess all potential impacts of the standard, we do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.
Real Estate Investments	Real Estate Investments Real estate investments represent investments in real estate entities that own real estate assets and are stated at the fair value of the net equity interest in the real estate investments as discussed below. Subsequent changes in fair value are recorded as unrealized gains or losses. Upon the disposition of a real estate investment, realized gains and losses are determined by deducting the proceeds received by the Predecessor from the basis of the real estate investment; any previously unrealized gains and losses are reversed. Distributions from real estate entities are recorded as dividend income when received to the extent distributed from the estimated taxable earnings and profits of the underlying investment vehicle and as a return of capital to the extent not in excess of that amount. Under investment company accounting, the statements of operations reflect the change in fair value of the real estate investments of the Easterly Funds, prior to the IPO, whether realized or unrealized.
Fair Value of Investments	Fair Value of Investments The fair value of the real estate investments is determined using a fair value hierarchy. The fair value hierarchy is based on the observability of inputs used to measure fair value and requires additional disclosure regarding the fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between marketplace participants at the measurement date (exit price). The fair value of an asset or a liability disregards transaction costs and assumes the asset or liability’s highest and best use. As the investments are in entities that invest in real estate, the estimated values are based on the underlying assets, liabilities, and cash flows of the related properties. The three levels of the fair value hierarchy are described below: Level 1 Valuation is based upon quoted prices for identical assets or liabilities in an active market. Level 2 Valuation is based upon observable inputs: a) Quoted prices for similar assets or liabilities in active markets, b) Quoted prices for identical or similar assets or liabilities in not active markets, or c) Model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 Valuation is based upon prices or valuation techniques that require assumptions not observable in the market which are significant to the overall fair value measurement. These unobservable inputs reflect the Predecessor’s own estimates about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). Valuation techniques include the use of discounted cash flow models, and similar techniques.
