Accounting Policies [Abstract]
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. 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. As of December 31, 2020, we wholly owned 79 operating properties in the United States, encompassing approximately 7.3 million leased square feet (square feet unaudited herein and throughout the Notes) in the aggregate, including 77 operating properties that were leased primarily to U.S. Government tenant agencies and two operating properties that were entirely leased to private tenants. As of December 31, 2020, our operating properties were 99% leased. For purposes of calculating percentage leased, we exclude from the denominator total square feet that was unleased and to which we attributed no value at the time of acquisition. In addition, we wholly owned one property under development that we expect will encompass approximately 0.2 million leased square feet upon completion. 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 and owned approximately 88.8% of the aggregate limited partnership interests in the Operating Partnership, which we refer to herein as common units, as of December 31, 2020. We have elected to be taxed as a REIT and 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. 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 unsecured 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 or lease 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 tenants 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. 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, 2 020 , 201 9 and 201 8 , 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, 2020 2019 2018 Net income $ 13,528 $ 8,224 $ 6,659 Book depreciation and amortization 93,367 92,248 66,260 Above/Below market lease amortization (5,894 ) (6,320 ) (8,593 ) Straight-line rent and other non-cash adjustments (3,377 ) (2,239 ) (5,619 ) Book/Tax differences on unearned rent (2,585 ) 1,646 3,714 Book/Tax differences on stock based compensation 3,634 4,156 3,039 Book/Tax differences on gain on sale of rental property 3,995 (6,245 ) — Book/Tax differences on fee waiver income from seller — — 1,400 Book/Tax differences on lease inducement 864 — — Other book/tax differences, net 137 588 749 Tax depreciation (52,152 ) (47,025 ) (34,612 ) Loss attributable to non-controlling interest (6,750 ) (6,922 ) (6,021 ) Taxable income subject to distribution requirements $ 44,767 (1) $ 38,111 (2) $ 26,976 (3) (1) The Company’s distributions are characterized as 53.63% ordinary taxable dividend and 46.37% return of capital. (2) 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 45.83% ordinary taxable dividend and 54.17% 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 Certain prior year amounts have been reclassified to conform to the current year presentation. Recently Adopted Accounting Pronouncements On January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). 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 Financial Accounting Standards Board issued ASU 2018-19, Codification Improvements to (Topic 326), Financial Instruments – Credit Losses (“ASU 2018-19”). ASU 2018-19 clarifies that receivables arising from operating leases are not within the scope of Accounting Standards Codification (“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. Impairment of receivables arising from operating leases should be accounted for in accordance with ASC Topic 842, Leases (“ASC 842”). We adopted ASU 2016-13 using the modified retrospective method and the adoption did not have a material impact on our consolidated financial statements. On January 1, 2020, the Company adopted ASU 2020-04 (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. Unlike most other ASU’s, the guidance in ASU 2020-04 will generally no longer be available to apply after December 31, 2022. As of January 1, 2020, the Company has elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients was applied prospectively and preserves the presentation of our derivatives consistent with past presentation, therefore, the adoption did not have a material impact on our consolidated financial statements.

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. Financial Covenant Considerations As of December 31, 2020, we were in compliance with all financial and other covenants related to our 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, 2020, the fair value of the revolving credit facility was determined by considering 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. At December 31, 2020, the carrying value of our revolving credit facility approximated fair value. As of December 31, 2020 and 2019, the fair value of the 2016 term loan facility was determined by considering the variable interest rate and credit spreads. We deem the fair value of the 2016 term loan facility as a Level 3 measurement. At December 31, 2020 and 2019, the fair value of our 2016 term loan facility was $99.4 million and $100.0 million, respectively. As of December 31, 2020 and 2019 At December 31, 2020 and 2019, the fair value of our 2018 term loan facility was $149.2 million and $150.0 million, respectively. As of December 31, 2020 and 2019, 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, 2020 and 2019, the fair value of our notes payable was $506.9 million and $471.7 million, respectively. As of December 31, 2020 and 2019, 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, 2020 and 2019, the fair value of our mortgage debt was $215.1 million and $212.5 million, respectively. Aggregate Debt Maturities The Company’s aggregate debt maturities based on outstanding principal as of December 31, 2020 are as follows (dollars in thousands): Total 2021 $ 4,233 2022 84,547 2023 171,286 2024 114,126 2025 7,550 Thereafter 601,700 983,442 Unamortized premium/discount & deferred financing (5,184 ) $ 978,258

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, 2020 and 2019 were classified as Level 2 of the fair value hierarchy. The carrying values of cash and cash equivalents, restricted cash, accounts receivable, other assets and accounts payable and accrued expenses are reasonable estimates of fair values because of the short maturities of these instruments. For our disclosure of debt fair values in Note 4, we estimated the fair value of our 2016 term loan facility and our 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, 2020 and 2019, 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. 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% on January 4, 2021. The performance period of the third tranche of LTIP units ended on December 31, 2020 and the Company’s total shareholder return over the performance period was sufficient for the grantees to earn an aggregate of 172,442 LTIP units under the applicable awards. Earned LTIP units vest 50% on January 19, 2021 and 50% will vest on January 4, 2022, 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, which vested on April 3, 2020. In connection with its 2018 annual meeting of stockholders, the Company issued an aggregate of 19,092 shares of restricted common stock to its non-employee directors pursuant to the 2015 Equity Incentive Plan, which vested on May 7, 2019.

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. The performance period of the first trading tranche of LTIP units ended on December 31, 2020 and the Company’s total shareholder return over the performance period was sufficient for the grantees to earn an aggregate of 98,776 LTIP units under the applicable awards. Earned LTIP units vested 50 % on January 19, 2021 and 50 % will vest on January 2, 2022, subject to the grantee’s continued employment. 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 vested 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.

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. On January 3, 2020, the Company granted an aggregate of 146,199 performance-based LTIP units to members of management pursuant to the 2015 Equity Incentive Plan, consisting of (i) 81,693 LTIP units that are subject to the Company achieving certain total shareholder return performance thresholds (on both an absolute and a relative basis) and (ii) 64,506 LTIP units that are subject to the Company achieving certain operational performance hurdles, in each case through a performance period ending on December 31, 2022.

A summary of our non-vested common share awards at December 31, 2020, 2019 and 2018 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, 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 Vested (24,236 ) $ 18.36 (27,732 ) $ 18.34 Granted 21,930 25.85 235,441 21.17 Forfeited — — — — Outstanding, December 31, 2020 89,891 $ 19.36 492,180 $ 19.88 (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 $4.1 million, $4.9 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, 2020, 2019 and 2018, respectively. As of December 31, 2020 unrecognized compensation expense for all awards was $5.1 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. We valued our LTIP unit awards that are subject to the Company achieving certain operational performance conditions at the grant date fair value, which was the market price of our common stock as of the applicable grant date. As of December 31, 2020, management considers it probable that the operational performance conditions on our 2020 grants will be achieved. We valued our service-based LTIP unit awards at the grant date fair value, which was the market price of our common stock as of the applicable grant date, discounted by the risk related to the timing of book-up events. For the LTIP unit awards granted that are subject to the Company achieving certain total shareholder return performance thresholds 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 had 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 had 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%. For LTIP units granted in January 2 020 we utilized a risk-free rate of %, 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 performance period. Based on the Company’s historical annualized quarterly dividend yields and current dividend yield , we utilized an expected dividend yield of % No additional shares of common stock or options were issued under the 2015 Equity Incentive Plan as of December 31, 2020. 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. In connection with the public offering, we also entered into forward sale agreements On March 27, 2019, we physically settled a portion of the forward sale agreements by issuing an aggregate of 6,700,000 shares of our common stock in exchange for approximately $119.2 million in net proceeds after deducting underwriting discounts and commissions and our offering expenses. On June 14, 2019, we completed the physical settlement of the remaining shares underlying the forward sale agreements by issuing an aggregate of 300,000 shares of our common stock in exchange for approximately $5.3 million in net proceeds after deducting underwriting discounts and commissions and our offering expenses. The Company accounted for the forward sale agreements as equity.

After the end of the performance period, the number of LTIP units, both vested and unvested, that LTIP award recipients have earned, if any, are entitled to receive dividends in an amount per LTIP unit equal to dividends, both regular and special, payable per common unit of our operating partnership. Holders of LTIP units that are not subject to the attainment of performance goals are entitled to receive dividends per LTIP unit equal to 100% of the dividend paid per common unit beginning on the grant date. ATM Programs On each of March 4, 2019 and December 20, 2019, the Company entered into separate equity distribution agreements with each of Citigroup Global Markets Inc., BMO Capital Markets Corp., BTIG, LLC, Capital One Securities, Inc., Jefferies LLC, Raymond James & Associates, Inc., RBC Capital Markets, LLC, SunTrust Robinson Humphrey, Inc. and Wells Fargo Securities, LLC pursuant to which it may issue and sell shares of its common stock having an aggregate offering price of up to $200.0 million and $300.0 million, respectively, from time to time (the “ATM Programs”) in negotiated transactions or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”). The ATM Programs implemented on March 4, 2019 and December 20, 2019 are referred to as the “March 2019 ATM Program” and “December 2019 ATM Program” respectively. Under each of the ATM Programs, the Company may also enter into one or more forward transactions (each, a “forward sale transaction”) under separate master forward sale confirmations and related supplemental confirmations with each of Citibank, N.A., Bank of Montreal, Jefferies LLC, Raymond James & Associates, Inc., Royal Bank of Canada and Wells Fargo Bank, National Association for the sale of shares of its common stock on a forward basis. The following table sets forth certain information with respect issuances, including in settlement of forward sales transactions, made under each of the ATM Programs as of December 31, 2020 (amounts in thousands except share amounts): March 2019 ATM Program December 2019 ATM Program For the Three Months Ended: Number of Shares Issued (1) Net Proceeds (1) Number of Shares Issued (1) Net Proceeds (1) March 31, 2020 200,000 $ 4,835 — $ — June 30, 2020 3,920,992 88,939 551,200 14,455 September 30, 2020 — — 1,475,991 33,541 December 31, 2020 — — 848,641 18,634 Total 4,120,992 $ 93,774 2,875,832 $ 66,630 (1) Includes shares issued by the Company, including in settlement of forward sales transactions.

Subject to our right to elect net share settlement, we expect to physically settle the forward sales transactions by the maturity dates set forth in each applicable forward sale transaction placement notice, which dates range from April 2021 to September 2021. Assuming the forward sales transactions are physically settled in full utilizing a net weighted average initial forward sales price of $25.96 per share, we expect to receive net proceeds of approximately $97.3 million, after deducting offering costs, subject to adjustments in accordance with the applicable forward sale transaction. The Company accounted for the forward sale agreements as equity. We have used the net proceeds received from such sales for general corporate purposes. As of December 31, 2020, we had approximately $140.6 million of gross sales of our common stock available under the December 2019 ATM Program and no remaining availability under the March 2019 ATM Program. Contribution of Property for Common Units On March 26, 2020, the Company acquired FBI / DEA – El Paso for which it paid, as partial consideration, 870,730 common units. The issuance of the common units was effected in reliance upon an exemption from registration provided by Section 4(a)(2) under the Securities Act. On November 9, 2018, the Company acquired TREAS – Birmingham for which it paid 271,918 common units.

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 of common stock and unvested 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, 2020, 2019 and 2018 (dollars in thousands, except per share amounts): For the years ended December 31, 2020 2019 2018 Numerator Net income (loss) $ 13,528 $ 8,224 $ 6,659 Less: Non-controlling interest in Operating Partnership (1,567 ) (1,017 ) (955 ) Net income (loss) available to Easterly Government Properties, Inc. 11,961 7,207 5,704 Less: Dividends on participating securities (289 ) (119 ) (1,123 ) Net income (loss) available to common stockholders $ 11,672 $ 7,088 $ 4,581 Denominator for basic EPS 78,219,491 68,769,526 53,511,137 Dilutive effect of share-based compensation awards 55,567 22,855 9,510 Dilutive effect of LTIP units (1) 507,050 416,585 1,135,544 Dilutive effect of shares issuable under forward sales agreements (2) 9,345 — 275,189 Denominator for diluted EPS 78,791,453 69,208,966 54,931,380 Basic EPS $ 0.15 $ 0.10 $ 0.09 Diluted EPS $ 0.15 $ 0.10 $ 0.08 (1) During the years ended December 31, 2020 and December 31, 2018, there were approximately 74,481 and 173,381 unvested performance-based LTIP units, respectively, 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 years ended December 31, 2020 and 2019, there were approximately 2,397,232 and 2,878,703 shares, respectively, of underlying unsettled forward sales 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

Leases	12 Months Ended

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 15.6 years as of December 31, 2020), 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 .

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. 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 unsecured 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 or lease 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 tenants 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. 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, 2 020 , 201 9 and 201 8 , 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, 2020 2019 2018 Net income $ 13,528 $ 8,224 $ 6,659 Book depreciation and amortization 93,367 92,248 66,260 Above/Below market lease amortization (5,894 ) (6,320 ) (8,593 ) Straight-line rent and other non-cash adjustments (3,377 ) (2,239 ) (5,619 ) Book/Tax differences on unearned rent (2,585 ) 1,646 3,714 Book/Tax differences on stock based compensation 3,634 4,156 3,039 Book/Tax differences on gain on sale of rental property 3,995 (6,245 ) — Book/Tax differences on fee waiver income from seller — — 1,400 Book/Tax differences on lease inducement 864 — — Other book/tax differences, net 137 588 749 Tax depreciation (52,152 ) (47,025 ) (34,612 ) Loss attributable to non-controlling interest (6,750 ) (6,922 ) (6,021 ) Taxable income subject to distribution requirements $ 44,767 (1) $ 38,111 (2) $ 26,976 (3) (1) The Company’s distributions are characterized as 53.63% ordinary taxable dividend and 46.37% return of capital. (2) 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 45.83% ordinary taxable dividend and 54.17% 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	Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements On January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). 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 Financial Accounting Standards Board issued ASU 2018-19, Codification Improvements to (Topic 326), Financial Instruments – Credit Losses (“ASU 2018-19”). ASU 2018-19 clarifies that receivables arising from operating leases are not within the scope of Accounting Standards Codification (“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. Impairment of receivables arising from operating leases should be accounted for in accordance with ASC Topic 842, Leases (“ASC 842”). We adopted ASU 2016-13 using the modified retrospective method and the adoption did not have a material impact on our consolidated financial statements. On January 1, 2020, the Company adopted ASU 2020-04 (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. Unlike most other ASU’s, the guidance in ASU 2020-04 will generally no longer be available to apply after December 31, 2022. As of January 1, 2020, the Company has elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients was applied prospectively and preserves the presentation of our derivatives consistent with past presentation, therefore, the adoption did not have a material impact on our consolidated financial statements.

Assuming the forward sales transactions are physically settled in full utilizing a net weighted average initial forward sales price of $25.96 per share, we expect to receive net proceeds of approximately $97.3 million, after deducting offering costs, subject to adjustments in accordance with the applicable forward sale transaction. The Company accounted for the forward sale agreements as equity.
