Organization and Basis of Presentation	1. Organization and Basis of Presentation Easterly Government Properties, Inc. (the “Company”) is a Maryland corporation that has elected to be taxed as a real estate investment trust (a “REIT”) under the Internal Revenue Code, as amended (the “Code”) commencing with its taxable year ended December 31, 2015. The operations of the Company are carried out primarily through Easterly Government Properties, LP (the “Operating Partnership”) and the wholly owned subsidiaries of the Operating Partnership. As used herein, the “Company,” “we,” “us,” or “our” refer to Easterly Government Properties, Inc. and its consolidated subsidiaries and partnerships, including the Operating Partnership, except where context otherwise requires. 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 (“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, 2019, we wholly owned 70 operating properties in the United States, including 68 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 6.5 million square feet (square feet unaudited herein and throughout the Notes) in the aggregate. In addition, we wholly owned two properties under development that we expect will encompass approximately 0.2 million square feet upon completion. 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. The Operating Partnership holds substantially all of our assets and conducts substantially all our business. The Company is the sole general partner of the Operating Partnership. The Company owned 88.6% of the aggregate limited partnership interests in the Operating Partnership (“common units”) at December 31, 2019. 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 other subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies 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 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 land, rental, discount and capitalization 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 at which time rental income recognition can commence and rental operating costs, real estate taxes, insurance, and other subsequent carrying costs are expensed as incurred. 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 on the accompanying Consolidated Balance Sheets include all cash and liquid investments that mature three months or less from when they were 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 on the accompanying Consolidated Balance Sheets 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 include accrued rental income and other tenant accounts receivable, respectively. The Company accrues rental and other tenant income earned, but not yet received, 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 carrying 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 for those leases which commenced prior to the adoption of Accounting Standards Codification Topic 842, Leases (“ASC 842”) on January 1, 2019, 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 commissions 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 is 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 qualifi es 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 gross basis by counterparty portfolio. Please refer to Note 5 for more information pertaining to interest rate derivatives. Deferred Revenue Deferred revenue consists primarily of lump sum reimbursements made by a tenant to the Company for landlord improvements in excess of a tenant improvement allowance. Lump sum reimbursements are recorded as Deferred revenue on the Consolidated Balance Sheets and are amortized over the life of the lease through Rental income. Deferred revenue also includes rent received in advance, which is recognized within Rental income once earned. 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. Further, Rental income includes certain tenant reimbursement income (real estate taxes, operating expenses, utility usage, and other reimbursements), which are accrued as variable lease payments in the same periods as the related expenses are incurred in accordance with ASC 842 which the Company adopted on January 1, 2019. Refer to the Recently Adopted Accounting Pronouncements for further discussion. Tenant reimbursement income includes income from tenant construction projects. 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. 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. Other income includes income on the associated tenant reimbursement construction projects, parking income and other miscellaneous 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, 201 9 , 201 8 and 201 7 , 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 the states in which we operate do not subject us to withholding tax requirements. The following table reconciles GAAP net income to taxable income (amounts in thousands): For the years ended December 31, 2019 2018 2017 Net income $ 8,224 $ 6,659 $ 5,389 Book depreciation and amortization 92,248 66,260 54,782 Above/Below market lease amortization (6,320 ) (8,593 ) (8,517 ) Straight-line rent and other non-cash adjustments (2,239 ) (5,619 ) (2,776 ) Book/Tax differences on unearned rent (874 ) 301 16 Book/Tax differences on stock based compensation 4,156 3,039 2,663 Book/Tax differences on development profit on lump sum payments 2,520 3,413 — Book/Tax differences on gain on sale of rental property (6,245 ) — — Book/Tax differences on fee waiver income from seller — 1,400 — Other book/tax differences, net 588 749 383 Tax depreciation (47,025 ) (34,612 ) (25,552 ) Loss attributable to non-controlling interest (6,922 ) (6,021 ) (5,180 ) Taxable income subject to distribution requirements $ 38,111 (1) $ 26,976 (2) $ 21,208 (3) (1) The Company’s distributions are characterized as 51.47% ordinary taxable dividend and 48.53% return of capital. (2) The Company’s distributions are characterized as 45.83% ordinary taxable dividend and 54.17% return of capital. (3) The Company’s distributions are characterized as 47.24% ordinary taxable dividend and 52.76% 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, LTIP units, and shares issuable under forward sales agreements. 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. Reclassifications and New Accounting Standards Certain prior year amounts have been reclassified to conform to the current year presentation. Amounts previously classified as tenant reimbursements which qualified for the practical expedient and were determined to be lease components have been reclassified to rental income to conform with current period presentation. Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases, along with various subsequent ASUs, 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 the previous guidance for operating leases. The Company adopted ASU 2016-02 on January 1, 2019 using the modified retrospective transition method such that we applied the standard as of the adoption date. Going forward under ASU 2016-02, it is required 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 within Corporate general and administrative expense on the Company's Consolidated Statements of Operations. Additionally, in July 2018, the FASB issued ASU 2018-11, Target Improvements to Topic 842 Leases. ASU 2018-11 provides lessors a practical expedient to not separate nonlease components from the associated lease component if the timing and pattern of transfer for the lease and nonlease components are the same and if the lease component, if accounted for separately, would be classified as an operating lease. Lease components are elements of an arrangement that provide the customer with the right to use an identified asset. Nonlease components are distinct elements of a contract that are not related to securing the use of the leased asset and revenue is recognized in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts and Customers (“ASC 606”). The Company assessed and concluded that the timing and pattern of transfer for nonlease components and the associated lease component are the same. The Company determined that the predominant component was the lease component and as such the Company has made a policy election to account for and present the lease component and the nonlease component as a single component in the revenue section of the Consolidated Statements of Operations. While application of the practical expedient did not result in a material change to the recognition of rental income, nonlease components included within Tenant reimbursement prior to the adoption of ASC Topic 842, Leases (“ASC 842”) are now included within Rental income on the Company's Consolidated Statements of Operations. In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842): Codification Improvements, which amended the transition guidance in ASC 842 to explicitly exempt entities from the interim disclosures required by ASC Topic ASC 205, Presentation of Financial Statements, related to changes in accounting principles. The provision is applicable at the time that entities adopt ASC 842, however implementation of this update did not have a material impact on our consolidated financial statements. The adoption of this standard also resulted in a cumulative effect adjustment of less than $0.1 million recorded as a decrease to Retained earnings as of January 1, 2019 in the accompanying Consolidated Statements of Equity. The cumulative effect adjustment related to initial direct costs of leases where the Company is the lessor that, as of January 1, 2019, had not begun to amortize and therefore are no longer allowed to be capitalized under the new standard. Additionally, as of January 1, 2019, the Company recognized an operating lease right-of-use asset and related operating lease liability of approximately $1.3 million on the accompanying Consolidated Balance Sheets, related to the leases where the Company is the lessee. The lease liability associated with these leases is reflected on the Company’s Consolidated Balance Sheets within Accounts payable and accrued liabilities and the right-of-use asset is included within Prepaid expenses and other assets. Associated lease expense will be recognized on a straight-line basis over the expected lease term based on the total lease payments and is included within Corporate general and administrative expense in the . On January 1, 2019, the Company adopted ASU 2017-12 (Topic 815), 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 Company adopted this ASU using the modified retrospective method and the adoption did not have a material impact on our consolidated financial statements . Recent Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The purpose of this updated guidance is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date by replacing the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to (Topic 326), Financial Instruments – Credit Losses. ASU 2018-19 clarifies that receivables arising from operating leases are not within the scope of ASC 326-20, “Financial Instruments – Credit Losses – Measured at Amortized Costs,” which addresses financial assets measured at amortized cost basis, including net investments in leases arising from sales -type and direct financing leases. Instead impairment of receivables arising from operating leases should be accounted for in accordance with ASC 842. Adoption of the standard is effective for the Company for reporting periods beginning after December 15, 2019 with early adoption permitted. The Company will adopt ASU 2016-13 and ASU 2018-19 effective January 1, 2020 using the modified retrospective approach. While the Company continues to assess all potential impacts of the standard, it does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

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 each of our revolving credit facility, our 2018 term loan facility and our 2016 term loan facility is based on the Company’s consolidated leverage ratio, as defined in the respective loan agreements. (2) Available capacity of $450.0 million and $315.2 million at December 31, 2019 and 2018, respectively, with an accordion feature that provides additional capacity of up to $250.0 million. (3) Our 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 2.67% annually, based on the Company’s consolidated leverage ratio, as defined in the 2016 term loan facility agreement. (5) Entered into four interest rate swaps with an effective date of December 13, 2018 with an aggregate notional value of $150.0 million to effectively fix the interest rate at 3.96% annually, based on the Company’s consolidated leverage ratio, as defined in the 2018 term loan facility agreement. (6) Effective interest rates are as follows: DEA – Pleasanton 1.8%, VA – Golden 5.03%, MEPCOM – Jacksonville 3.89%, USFS II – Albuquerque 3.92%, ICE – Charleston 3.93%, VA – Loma Linda 3.78%, CBP – Savannah 4.12%. 2019 Activity On September 12, 2019, the Operating Partnership issued an aggregate of $275.0 million of fixed rate, senior unsecured notes (the “2019 senior unsecured notes”) in a private placement pursuant to a purchase agreement among the Operating Partnership, the Company and the purchasers of the 2019 senior unsecured notes dated July 30, 2019 (the “Purchase Agreement”). The 2019 senior unsecured notes consist of (i) 3.73% Series A Senior Notes due September 12, 2029 in an aggregate principal amount of $85.0 million, (ii) 3.83% Series B Senior Notes due September 12, 2031 in an aggregate principal amount of $100.0 million, and (iii) 3.98% Series C Senior Notes due September 12, 2034 in an aggregate principal amount of $90.0 million. The 2019 senior unsecured 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 2019 senior unsecured 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 2019 senior unsecured 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 2019 senior unsecured notes will become due and payable at the option of the holders. The Purchase Agreement and the 2019 senior unsecured notes also contains 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) and 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 2019 senior unsecured notes will become due and payable at the option of the holders. 2018 Activity On June 18, 2018, we entered into an amended and restated senior unsecured credit facility (our “amended senior unsecured credit facility”). Our amended senior unsecured credit facility increased the total borrowing capacity of our existing senior unsecured credit facility by $200.0 million for a total credit facility size of $600.0 million, consisting of two components: (i) a $450.0 million senior unsecured revolving credit facility (the “revolving credit facility”), and (ii) a $150.0 million senior unsecured term loan facility (the “2018 term loan facility”). The revolving credit facility also includes an accordion feature that will provide us with additional capacity, subject to the satisfaction of customary terms and conditions, of up to $250.0 million. The Operating Partnership is the borrower, and we and certain of our subsidiaries that directly own certain of our properties are guarantors under our amended senior unsecured credit facility. The revolving credit facility matures in four years and the 2018 term loan facility matures in five years. In addition, the revolving credit facility has two six-month as-of-right extension options subject to certain conditions and the payment of an extension fee. Our amended senior unsecured credit facility bears interest, at our option, either at: • a Eurodollar rate equal to a periodic fixed rate equal to LIBOR plus, a margin ranging from 1.25% to 1.80% for advances under the revolving credit facility and a margin ranging from 1.20% to 1.75% for advances under the 2018 term loan facility ; or • a fluctuating rate equal to the sum of (a) the highest of (x) Citibank, N.A.’s base rate, (y) the federal funds effective rate plus 0.50% and (z) the one-month Eurodollar rate plus 1.00% plus (b) a margin ranging from 0.25% to 0.80% for advances under the revolving credit facility and a margin ranging from 0.20% to 0.75% for advances under the 2018 term loan facility , in each case with a margin based on our leverage ratio. The 2018 term loan facility had a 364-day delayed draw period and is prepayable without penalty for the entire term of the loan. On September 10, 2018, we fully drew $150.0 million on the 2018 term loan facility. On June 18, 2018, we entered into a second amendment to our existing $100.0 million senior unsecured term loan facility (the “2016 term loan facility”). The second amendment amends certain covenants and other provisions in the 2016 term loan facility to conform to changes made to such covenants and other provisions in our amended senior unsecured credit facility. On October 3, 2018, we entered into a third letter amendment (the “Third Amendment”) to the 2016 term loan facility. The Third Amendment reduced the interest rate margin applicable to borrowings under the 2016 term loan facility and extended the maturity date by six months to March 29, 2024. Financial Covenant Considerations The Company was in compliance with all financial and other covenants as of December 31, 2019 related to its revolving credit facility, 2016 term loan facility, 2018 term loan facility, notes payable and mortgage notes payable. Fair Value of Debt As of December 31, 2019 and 2018, the carrying value of the 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 the senior unsecured revolving credit facility as a Level 3 measurement. As of December 31, 2019 and 2018, the carrying value of the 2016 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 the 2016 term loan facility as a Level 3 measurement. As of December 31, 2019 and 2018, the carrying value of the 2018 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 the 2018 term loan facility as a Level 3 measurement. As of December 31, 2019 and 2018, 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, 2019 and 2018, the fair value of our notes payable was $471.7 million and $172.0 million, respectively. As of December 31, 2019 and 2018, 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, 2019 and 2018, the fair value of our mortgage debt was $212.5 million and $206.8 million, respectively. Aggregate Debt Maturities The Company’s aggregate debt maturities based on outstanding principal as of December 31, 2019 are as follows (dollars in thousands): Total 2020 $ 3,564 2021 4,233 2022 5,297 2023 171,285 2024 114,126 Thereafter 609,250 907,755 Unamortized premium/discount & deferred financing (5,914 ) $ 901,841

Derivatives and Hedging Activities The following table sets forth the key terms and fair values of our interest rate swap derivatives, each of which was designated as a cash flow hedge (dollars in thousands): Fair Value at December 31, Notional Amount Fixed Rate Floating Rate Index Effective Date Expiration Date 2019 2018 $ 100,000 1.41 % One-Month LIBOR March 29, 2017 September 29, 2023 $ 541 $ 4,563 150,000 2.71 % One-Month LIBOR December 13, 2018 June 19, 2023 (5,837 ) (1,797 ) The table below sets forth the fair value of our interest rate derivatives as well as their classification on our consolidated balance sheets (dollars in thousands): Fair Value at December 31, Balance Sheet Line Item 2019 2018 Interest rate swaps-Asset $ 541 $ 4,563 Interest rate swaps-Liability (5,837 ) (1,797 ) Cash Flow Hedges of Interest Rate Risk 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, 2019 and 2018, the Company did not record any hedge ineffectiveness related to the hedged derivatives. Amounts reported in accumulated other comprehensive income (loss) related to derivatives designated as qualifying cash flow hedges will be reclassified to interest expense as interest payments are made on the Company's variable rate debt. The Company estimates that $1.5 million will be reclassified from accumulated other comprehensive income as a decrease to interest expense over the next 12 months. The table below presents the effects of our interest rate derivatives on our consolidated statements of operations and comprehensive income (dollars in thousands): For the years ended December 31, 2019 2018 2017 Unrealized gain (loss) recognized in AOCI $ (7,884 ) $ (713 ) $ 63 Gain (loss) reclassified from AOCI into interest expense 177 552 (183 ) 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, 2019, the net fair value of derivatives in a liability position related to these agreements was $5.5 million. As of December 31, 2019, the Company had not breached the provisions of these agreements and has not posted any collateral related to these agreements.

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. Recurring fair value measurements 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 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, 2019 and 2018 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 the 2016 and 2018 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 judgment. Settlement at such fair value amounts may not be possible and may not be a prudent management decision. The table below presents the Company’s assets and liabilities measured at fair value on a recurring basis as of December 31, 2019 and 2018, aggregated by the level in the fair value hierarchy within which those measurements fall (amounts in thousands).

Equity [Abstract]
Equity	7. Equity 2015 Equity Incentive Plan Our board of directors adopted, and our sole stockholder approved, our 2015 Equity Incentive Plan, as amended (the “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. 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 of the Company’s board of directors 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 and 50% on February 6, 2019, subject to the grantee’s continued employment. 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 vested on May 7, 2018. On January 4, 2018, the Company granted an aggregate of 173,381 performance-based LTIP units to members of management under the 2015 Equity Incentive Plan, subject to the Company achieving certain absolute and relative total shareholder returns through the performance period. The awards consist of three separate tranches of 32,448 LTIP units, 55,463 LTIP units and 85,470 LTIP units with performance periods ending on December 31, 2018, December 31, 2019 and December 31, 2020, respectively. The performance criteria for each tranche is based 75% on the Company’s absolute total shareholder return performance and 25% on the Company’s relative total shareholder return performance during the relevant performance period, with 50% of the LTIP units vesting when earned following the end of the applicable performance period and 50% of the earned award subject to an additional one year of vesting. During the performance period ending December 31, 2018, the Company’s total shareholder return performance (on both an absolute and relative basis) did not achieve the applicable thresholds for payouts. Accordingly, the compensation committee of the Company’s board of directors determined that none of the 32,448 LTIP units subject to the performance period ending December 31, 2018 had been earned. Such LTIPs were therefore forfeited and added back to the shares of common stock of the Company available for issuance under the 2015 Equity Incentive Plan. The performance period of the second tranche of LTIP units ended on December 31, 2019 and the Company’s total shareholder return over the performance period was sufficient for the grantees to earn an aggregate of 122,159 LTIP units under the applicable awards. Earned LTIP units vested 50% on January 16, 2020 and 50% will vest on January 4, 2021, subject to the grantee’s continued employment. On April 3, 2018, the Company issued an aggregate of 2,236 shares of restricted common stock to certain employees pursuant to the 2015 Equity Incentive Plan. The restricted common stock grants will vest upon the second anniversary of the grant date so long as the grantee remains an employee of the Company on such date. In connection with our 2018 annual meeting of stockholders, we issued an aggregate of 19,092 shares of restricted common stock to our non-employee directors pursuant to the 2015 Equity Incentive Plan, which vested on May 7, 2019. On January 18, 2019, the Company granted an aggregate of 143,538 performance-based LTIP units to members of management pursuant to the 2015 Equity Incentive Plan, subject to the Company achieving certain absolute and relative total shareholder returns through the performance period. The awards consist of two separate tranches of 45,238 LTIP units and 98,300 LTIP units with performance periods ending on December 31, 2020 and December 31, 2021, respectively. Fifty percent of the LTIP units vest when earned following the end of the applicable performance period and fifty percent of the earned award is subject to an additional one year of vesting. On January 18, 2019, the Company granted an aggregate of 54,041 shares of restricted common stock to members of management pursuant to the 2015 Equity Incentive Plan, of which an aggregate of 17,645 shares will vest on January 18, 2021 and an aggregate of 36,396 shares will vest on January 18, 2022. On March 11, 2019, the Company issued an aggregate of 3,080 shares of restricted common stock to certain employees pursuant to the 2015 Equity Incentive Plan. The shares of restricted common stock will vest upon the second anniversary of the grant date so long as the grantee remains an employee of the Company on such date. In connection with the Company’s 2019 annual meeting of stockholders, we issued an aggregate of 22,000 shares of restricted common stock to our non-employee directors pursuant to the 2015 Equity Incentive Plan. The shares of restricted common stock will vest upon the earlier of the anniversary of the grant date or the next annual stockholder meeting. On June 13, 2019, the Company issued 10,840 shares of restricted common stock to a member of management pursuant to the 2015 Equity Incentive Plan. The shares of restricted common stock will vest on February 28, 2022, subject, to the grantee’s continued employment and the other terms of the awards. On December 19, 2019, the Company granted an aggregate of 99,803 LTIP units to certain members of management pursuant to the 2015 Equity Incentive Plan , which became fully vested upon grant and are subject to certain restrictions on transfer as set forth in the applicable award agreement for a period of three years beginning on the grant date . A summary of our non-vested common share awards at December 31, 2019, 2018 and 2017 is as follows: Restricted Shares Restricted Shares Weighted average grant date fair value LTIP Units (1) LTIP Units Weighted average grant date fair value 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 Vested (15,220 ) $ 19.71 (463,000 ) $ 8.91 Granted 21,328 20.87 173,381 18.31 Forfeited — — — — Outstanding, December 31, 2018 24,020 $ 20.74 636,381 $ 11.47 Vested (21,784 ) $ 20.81 (562,803 ) $ 10.97 Granted 89,961 17.49 243,341 19.75 Forfeited — — (32,448 ) 19.15 Outstanding, December 31, 2019 92,197 $ 17.55 284,471 $ 18.66 (1) Reflects the number of LTIP units issued to the grantee on the grant date which may be different from the number of LTIP units actually earned in the case of performance-based LTIP units. We recognized $4.9 million, $3.0 million and $3.0 million in compensation expense, related to the restricted common stock and the LTIP unit awards, for the years ended December 31, 2019, 2018 and 2017, respectively. As of December 31, 2019 unrecognized compensation expense for all awards was $3.6 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 2018 we utilized a risk-free rate of 2.1%, 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 16.0% was derived from the observed historical volatility of the common stock prices of a select group of peer companies within the REIT industry and the observed implied volatility on the Company’s stock options. Based on the selected dividend yields of guideline companies and expected dividend levels, we utilized an expected dividend yield of 5.0%. For LTIP units granted in January 2019 we utilized a risk-free rate of 2.6%, derived from the yield of zero-coupon U.S. Treasury securities for a three-year holding period as of the grant date. Since the Company has a limited amount of operating history, the expected volatility assumption of 19.0% was derived from the observed historical volatility of the common stock prices of a select group of peer companies within the REIT industry and the observed implied volatility on the Company’s stock options. Based on the selected dividend yields of guideline companies and expected dividend levels, we utilized an expected dividend yield of 5.6%. For LTIP units granted in December 2019 we utilized a risk-free rate of 1.73%, derived from the yield of zero-coupon U.S. Treasury securities for a three-year holding period as of the grant date. The expected volatility assumption of 16.0% was derived from the Company’s observed historical volatility equal to the three-year post-vesting restriction period. Based on the selected dividend yields of guideline companies and expected dividend levels, we utilized an expected dividend yield of 4.9%. No additional shares of common stock or options were issued under the 2015 Equity Incentive Plan as of December 31, 2019. Underwritten Public Offering of Common Stock 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. Offering of Common Stock on a Forward Basis On June 21, 2018, we completed an underwritten public offering of an aggregate of 20,700,000 The public offering included 13,700,000 shares sold by us directly to the underwriters (including 2,700,000 shares pursuant to the underwriters’ exercise of their option to purchase additional shares), resulting in net proceeds to us of approximately $252.9 million, after deducting underwriting discounts and commissions and our offering expenses.

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, 2019, 2018 and 2017 (amounts in thousands, except per share amounts): For the years ended December 31, 2019 2018 2017 Numerator Net income (loss) $ 8,224 $ 6,659 $ 5,389 Less: Non-controlling interest in Operating Partnership (1,017 ) (955 ) (941 ) Net income (loss) available to Easterly Government Properties, Inc. 7,207 5,704 4,448 Less: Dividends on participating securities (119 ) (1,123 ) (110 ) Net income (loss) available to common stockholders $ 7,088 $ 4,581 $ 4,338 Denominator for basic EPS 68,769,526 53,511,137 39,607,740 Dilutive effect of share-based compensation awards 22,855 9,510 11,384 Dilutive effect of LTIP units (1) 416,585 1,135,544 1,944,416 Dilutive effect of shares issuable under forward sales agreements (2) — 275,189 — Denominator for diluted EPS 69,208,966 54,931,380 41,563,540 Basic EPS $ 0.10 $ 0.09 $ 0.11 Diluted EPS $ 0.10 $ 0.08 $ 0.10 (1) During the year ended December 31, 2018, there were approximately 173,381 unvested performance-based LTIP units that were not included in the computation of diluted earnings per share because to do so would have been antidilutive for the period. (2) During the year ended December 31, 2019, there were approximately 2,878,703 shares of unsettled forward sale transactions that were not included in the computation of diluted earnings per share because to do so would have been antidilutive for the period.

Leases [Abstract]
Leases	9. Leases Lessor The Company leases commercial space to the U.S. Government through the GSA or other federal agencies or nongovernmental tenants. These leases may contain extension options that are predominately at the sole discretion of the tenant. Certain of our leases contain a “soft-term” period of the lease, meaning that the U.S. Government tenant agency has the right to terminate the lease prior to its stated lease end date. While certain of our leases are contractually subject to early termination, we do not believe that our tenant agencies are likely to terminate these leases early given the build-to-suit features at the properties subject to the leases, the weighted average age of these properties based on the date the property was built or renovated-to-suit, where applicable (approximately 12.8 years as of December 31, 2019), the mission-critical focus of the properties subject to the leases and the current level of operations at such properties. Certain lease agreements include variable lease payments that, in the future, will vary based on changes in inflationary measures, real estate tax rates, usage, or share of expenditures of the leased premises . As discussed above in Note 2, the Company elected a practical expedient to not separate nonlease components from the associated lease component if the time and pattern of transfer for the lease and nonlease components are the same and if the lease component, if accounted for separately, would be classified as an operating lease. On August 27, 2019, the FDA – Alameda development project was substantially completed and a 20-year non-cancelable lease commenced with the GSA for the beneficial use of the FDA. Upon completion and their acceptance of work, the U.S. Government paid a $52.5 million lump sum reimbursement to the Company for landlord improvements in excess of the U.S. Government’s tenant improvement allowance. The Company recorded the payment as Deferred revenue on the Consolidated Balance Sheet and began amortizing the amount over the life of the lease through Rental income. The following table summarizes the maturity of fixed lease payments under the Company’s leases as of December 31, 2019 (amounts in thousands): Payments due by period Total 2020 2021 2022 2023 2024 Thereafter Fixed lease payments $ 1,518,216 179,205 156,033 138,797 130,684 119,757 793,740 Prior to the adoption of ASC 842 on January 1, 2019, the Company’s leases associated with its operating properties fell under the guidance of ASC Topic ASC 840, Leases (“ASC 840”). As of December 31, 2018, the future non-cancelable minimum contractual rent payments on our operating properties were as follows (amounts in thousands): Payments due by period Total 2019 2020 2021 2022 2023 Thereafter Operating Leases Minimum lease payments $ 1,251,546 151,152 139,315 116,827 99,822 92,392 652,038 Information about our leases for development properties as of December 31, 2019 is set forth in the table below: Property Name Location Tenant Property Type (1) Lease Term Estimated Rentable Square Feet FDA - Atlanta Atlanta, GA Food and Drug Administration L 20-year 162,000 FDA - Lenexa Lenexa, KS Food and Drug Administration L 20-year (2) 59,690 Total 221,690 (1) L=Laboratory (2) The 20-year lease term includes a firm term of 15 years and a soft term of five years. Lessee In October 2015, we entered into a sublease agreement for office space in Washington, D.C. with a commencement date of March 2016 and expiration date of June 2021. We also lease office space in San Diego, CA under an operating lease that commenced February 2015 and expires in April 2022. Neither of the leases contain extension options, however they do include variable lease payments that, in the future, will vary based on changes in real estate tax rates, usage, or share of expenditures of the leased premises. The Company has elected not to separate lease and nonlease components for both corporate office leases. As of December 31, 2019, the unamortized balance associated with the Company’s right-of-use operating lease asset and operating lease liability for the Company’s two office leases was $0.8 million. The Company used its incremental borrowing rate, which was arrived at utilizing prevailing market rates and the spread on the revolving credit facility, in order to determine the net present value of the minimum lease payments. The following table provides quantitative information for the Company’s operating leases for the year ended December 31, 2019 (amounts in thousands): For the year ended December 31, 2019 Operating leases costs $ 461 Other Information Weighted average remaining lease terms (in years) 1.91 Weighted average discount rate 3.84 % In addition, the maturity of fixed lease payments under the Company’s corporate office leases as of December 31, 2019 is summarized in the table below (amounts in thousands): Payments due by period Total 2020 2021 2022 2023 2024 Thereafter Fixed lease payments $ 913 496 352 65 — — — Prior to the adoption of ASC 842 on January 1, 2019, the Company’s corporate office leases fell under the guidance of ASC 840.

The duration of the majority of tenant construction project reimbursement arrangements are less than a year and payment is typically due once a project is complete and work has been accepted by the tenant. There were no projects ongoing as of December 31, 2019 or as of December 31, 2018 with a duration of greater than one year. During the twelve months ended December 31, 2019 and 2018, the Company also recognized $1.0 million and $0.2 million, respectively, in parking garage income generated from the operations of a parking garage situated on both the Various GSA – Buffalo and Various GSA - Portland properties acquired during the twelve months ended December 31, 2019 and December 31, 2018, respectively.

As of December 31, 2019 there was $0.1 million in Accounts receivable attributable to parking garage income and less than $0.1 million in Accounts receivable attributable to parking garage income as of December 31, 2018. Additionally, the Company also earns credits on its utility bills at certain properties for the use of energy efficient building materials, which also falls within the scope of ASC 606. The pattern of recognition for the credits is in line with the recognition of the associated utility expense. The Company recognized $0.1 million in energy credit income during the twelve months ended December 31, 2019 and less than $0.1 million during the twelve months ended December 31, 2018.

Risks And Uncertainties [Abstract]
Concentrations Risk	12. 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, 2019, the GSA and other federal agency accounted for approximately 98.3% of rental income and non-governmental tenants accounted for the remaining approximately 1.7%. At December 31, 2018, the GSA and other federal agency accounted for approximately 98.8% of rental income and non-governmental tenants accounted for the remaining approximately 1.2%. At December 31, 2019, 18 of our 70 operating properties were located in California, accounting for approximately 20.5% of our total rentable square feet and approximately 26.9% of our total annualized lease income. At December 31, 2018, 17 of our 62 operating properties were located in California, accounting for approximately 23.9% of our total rentable square feet and approximately 30.1% 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.

Accounting Policies [Abstract]
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 land, rental, discount and capitalization 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 at which time rental income recognition can commence and rental operating costs, real estate taxes, insurance, and other subsequent carrying costs are expensed as incurred. 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 on the accompanying Consolidated Balance Sheets include all cash and liquid investments that mature three months or less from when they were 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 on the accompanying Consolidated Balance Sheets 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 include accrued rental income and other tenant accounts receivable, respectively. The Company accrues rental and other tenant income earned, but not yet received, 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 carrying 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 for those leases which commenced prior to the adoption of Accounting Standards Codification Topic 842, Leases (“ASC 842”) on January 1, 2019, 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 commissions 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 is 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 qualifi es 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 gross basis by counterparty portfolio. Please refer to Note 5 for more information pertaining to interest rate derivatives.
Deferred Revenue	Deferred Revenue Deferred revenue consists primarily of lump sum reimbursements made by a tenant to the Company for landlord improvements in excess of a tenant improvement allowance. Lump sum reimbursements are recorded as Deferred revenue on the Consolidated Balance Sheets and are amortized over the life of the lease through Rental income. Deferred revenue also includes rent received in advance, which is recognized within Rental income once earned.
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.
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. Further, Rental income includes certain tenant reimbursement income (real estate taxes, operating expenses, utility usage, and other reimbursements), which are accrued as variable lease payments in the same periods as the related expenses are incurred in accordance with ASC 842 which the Company adopted on January 1, 2019. Refer to the Recently Adopted Accounting Pronouncements for further discussion. Tenant reimbursement income includes income from tenant construction projects. 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. 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. Other income includes income on the associated tenant reimbursement construction projects, parking income and other miscellaneous 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, 201 9 , 201 8 and 201 7 , 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 the states in which we operate do not subject us to withholding tax requirements. The following table reconciles GAAP net income to taxable income (amounts in thousands): For the years ended December 31, 2019 2018 2017 Net income $ 8,224 $ 6,659 $ 5,389 Book depreciation and amortization 92,248 66,260 54,782 Above/Below market lease amortization (6,320 ) (8,593 ) (8,517 ) Straight-line rent and other non-cash adjustments (2,239 ) (5,619 ) (2,776 ) Book/Tax differences on unearned rent (874 ) 301 16 Book/Tax differences on stock based compensation 4,156 3,039 2,663 Book/Tax differences on development profit on lump sum payments 2,520 3,413 — Book/Tax differences on gain on sale of rental property (6,245 ) — — Book/Tax differences on fee waiver income from seller — 1,400 — Other book/tax differences, net 588 749 383 Tax depreciation (47,025 ) (34,612 ) (25,552 ) Loss attributable to non-controlling interest (6,922 ) (6,021 ) (5,180 ) Taxable income subject to distribution requirements $ 38,111 (1) $ 26,976 (2) $ 21,208 (3) (1) The Company’s distributions are characterized as 51.47% ordinary taxable dividend and 48.53% return of capital.

(3) The Company’s distributions are characterized as 47.24% ordinary taxable dividend and 52.76% 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, LTIP units, and shares issuable under forward sales agreements. 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.
Reclassifications and New Accounting Standards	Reclassifications and New Accounting Standards Certain prior year amounts have been reclassified to conform to the current year presentation. Amounts previously classified as tenant reimbursements which qualified for the practical expedient and were determined to be lease components have been reclassified to rental income to conform with current period presentation.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases, along with various subsequent ASUs, 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 the previous guidance for operating leases. The Company adopted ASU 2016-02 on January 1, 2019 using the modified retrospective transition method such that we applied the standard as of the adoption date. Going forward under ASU 2016-02, it is required 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 within Corporate general and administrative expense on the Company's Consolidated Statements of Operations. Additionally, in July 2018, the FASB issued ASU 2018-11, Target Improvements to Topic 842 Leases. ASU 2018-11 provides lessors a practical expedient to not separate nonlease components from the associated lease component if the timing and pattern of transfer for the lease and nonlease components are the same and if the lease component, if accounted for separately, would be classified as an operating lease. Lease components are elements of an arrangement that provide the customer with the right to use an identified asset. Nonlease components are distinct elements of a contract that are not related to securing the use of the leased asset and revenue is recognized in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts and Customers (“ASC 606”). The Company assessed and concluded that the timing and pattern of transfer for nonlease components and the associated lease component are the same. The Company determined that the predominant component was the lease component and as such the Company has made a policy election to account for and present the lease component and the nonlease component as a single component in the revenue section of the Consolidated Statements of Operations. While application of the practical expedient did not result in a material change to the recognition of rental income, nonlease components included within Tenant reimbursement prior to the adoption of ASC Topic 842, Leases (“ASC 842”) are now included within Rental income on the Company's Consolidated Statements of Operations. In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842): Codification Improvements, which amended the transition guidance in ASC 842 to explicitly exempt entities from the interim disclosures required by ASC Topic ASC 205, Presentation of Financial Statements, related to changes in accounting principles. The provision is applicable at the time that entities adopt ASC 842, however implementation of this update did not have a material impact on our consolidated financial statements. The adoption of this standard also resulted in a cumulative effect adjustment of less than $0.1 million recorded as a decrease to Retained earnings as of January 1, 2019 in the accompanying Consolidated Statements of Equity. The cumulative effect adjustment related to initial direct costs of leases where the Company is the lessor that, as of January 1, 2019, had not begun to amortize and therefore are no longer allowed to be capitalized under the new standard. Additionally, as of January 1, 2019, the Company recognized an operating lease right-of-use asset and related operating lease liability of approximately $1.3 million on the accompanying Consolidated Balance Sheets, related to the leases where the Company is the lessee. The lease liability associated with these leases is reflected on the Company’s Consolidated Balance Sheets within Accounts payable and accrued liabilities and the right-of-use asset is included within Prepaid expenses and other assets. Associated lease expense will be recognized on a straight-line basis over the expected lease term based on the total lease payments and is included within Corporate general and administrative expense in the . On January 1, 2019, the Company adopted ASU 2017-12 (Topic 815), 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 Company adopted this ASU using the modified retrospective method and the adoption did not have a material impact on our consolidated financial statements .
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The purpose of this updated guidance is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date by replacing the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to (Topic 326), Financial Instruments – Credit Losses. ASU 2018-19 clarifies that receivables arising from operating leases are not within the scope of ASC 326-20, “Financial Instruments – Credit Losses – Measured at Amortized Costs,” which addresses financial assets measured at amortized cost basis, including net investments in leases arising from sales -type and direct financing leases. Instead impairment of receivables arising from operating leases should be accounted for in accordance with ASC 842. Adoption of the standard is effective for the Company for reporting periods beginning after December 15, 2019 with early adoption permitted. The Company will adopt ASU 2016-13 and ASU 2018-19 effective January 1, 2020 using the modified retrospective approach. While the Company continues to assess all potential impacts of the standard, it does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.
