Accounting Policies [Abstract]
Organization and Basis of Presentation	1. Organization and Basis of Presentation The information contained in the following notes to the consolidated financial statements is condensed from that which would appear in the annual consolidated financial statements; accordingly, the consolidated financial statements included herein should be reviewed in conjunction with the consolidated financial statements for the fiscal year ended December 31, 2019, and related notes thereto, included in the Annual Report on Form 10-K of Easterly Government Properties, Inc. (the “Company”) for the year ended December 31, 2019 filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 25, 2020. The Company is a Maryland corporation that has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”), commencing with its taxable year ended December 31, 2015. The operations of the Company are carried on primarily through Easterly Government Properties LP (the “Operating Partnership”) and the wholly owned subsidiaries of the Operating Partnership. As used herein, the “Company 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 September 30, 2020, we wholly owned 76 operating properties in the United States, encompassing approximately 7.0 rentable million square feet in the aggregate, including 73 operating properties that were leased primarily to U.S. Government tenant agencies, two operating properties that were entirely leased to private tenants and one operating property available to be leased. As of September 30, 2020, our operating properties were 99% leased. For purposes of calculating percentage leased, we exclude from the denominator total rentable 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 rentable square feet upon completion. The Operating Partnership holds substantially all of our assets and conducts substantially all of our business. We are the sole general partner of the Operating Partnership. We owned approximately 88.7% of the aggregate limited partnership interests in the Operating Partnership (“common units”) at September 30, 2020. 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, Easterly Government Properties TRS, LLC, Easterly Government Services, LLC, the Operating Partnership and its other subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Basis of Presentation The condensed consolidated financial statements included herein are unaudited; however, they include all adjustments (consisting only of normal recurring adjustments) which, in the opinion of management, are necessary to state fairly the consolidated financial position of the Company at September 30, 2020, and the consolidated results of operations for the three and nine months ended September 30, 2020 and 2019 and the consolidated cash flows for the nine months ended September 30, 2020 and 2019. The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year. 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. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, including the impact of extraordinary events such as the novel coronavirus (COVID-19) pandemic, the results of which form the basis for making judgements about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or condition s .

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The significant accounting policies used in the preparation of the Company’s condensed consolidated financial statements are disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. 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 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”). The Company 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 the Company’s derivatives consistent with past presentation, therefore, the adoption did not have a material impact on our consolidated financial statements.

We allocated the aggregate purchase price of these acquisitions based on the estimated fair values of the acquired assets and assumed liabilities as follows (amounts in thousands): Total Real estate Land $ 17,754 Building 114,540 Acquired tenant improvements 4,394 Total real estate 136,688 Intangible assets In-place leases 10,361 Acquired leasing commissions 5,645 Above-market leases 6,553 Total intangible assets 22,559 Intangible liabilities Below-market leases (8,491 ) Total intangible liabilities (8,491 ) Accounts payable, accrued expenses and other liabilities Contingent consideration (336 ) Purchase price $ 150,420 We did not assume any debt upon acquisition of these properties. The intangible assets and liabilities of operating properties acquired during the nine months ended September 30, 2020 have a weighted average amortization period of 9.68 years as of September 30, 2020. During the nine months ended September 30, 2020, we included $7.1 million of revenues and $2.2 million of net income in our Consolidated Statements of Operations related to the operating properties acquired. During the nine months ended September 30, 2020, we incurred $1.7 million of acquisition-related expenses mainly consisting of internal costs associated with property acquisitions. Development Placed in Service On September 25, 2020, the FDA – Lenexa development project was substantially completed and a 20-year lease commenced with the GSA for the beneficial use of the Food and Drug Administration (“FDA”). Consolidated Real Estate and Intangibles In addition to the operating property acquisitions and development property placed in service, we acquired a 597,426 square foot parcel of land in Lincoln, Nebraska, which is adjacent to our USCIS – Lincoln facility, during the nine months ended September 30, 2020.

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 as of September 30, 2020 (amounts in thousands): Notional Amount Fixed Rate Floating Rate Index Effective Date Expiration Date Fair Value $ 100,000 1.41 % One-Month LIBOR March 29, 2017 September 29, 2023 $ (3,774 ) $ 150,000 2.71 % One-Month LIBOR December 13, 2018 June 19, 2023 $ (10,402 ) The table below sets forth the fair value of our interest rate derivatives as well as their classification on our Consolidated Balance Sheet (amounts in thousands): Balance Sheet Line Item As of September 30, 2020 Interest rate swaps - Asset $ — Interest rate swaps - Liability $ (14,176 ) Cash Flow Hedges of Interest Rate Risk The gains or losses on derivatives designated and that qualify as cash flow hedges is recorded in Accumulated other comprehensive income (loss) (“AOCI”) and will be reclassified to interest expense in the period that the hedged forecasted transactions affect earnings on the Company’s variable rate debt. Amounts reported in AOCI 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 $5.1 million will be reclassified from AOCI as an increase 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 (amounts in thousands): For the three months ended September 30, For the nine months ended September 30, 2020 2019 2020 2019 Unrealized loss recognized in AOCI $ (60 ) $ (1,774 ) $ (11,643 ) $ (9,601 ) Gain (loss) reclassified from AOCI into interest expense (1,292 ) 33 (2,763 ) 396 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 such indebtedness. As of September 30, 2020, the fair value of derivatives in a liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $14.7 million. As of September 30, 2020, the Company had not breached the provisions of these agreements and had not posted any collateral related to these agreements. If the Company breached any of these provisions it would be required to settle its obligations under the agreements at their termination value of $14.7 million.

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 September 30, 2020 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 September 30, 2020, aggregated by the level in the fair value hierarchy within which those measurements fall (amounts in thousands): As of September 30, 2020 Balance Sheet Line Item Level 1 Level 2 Level 3 Interest rate swaps - Asset $ — $ — $ — Interest rate swaps - Liability $ — $ (14,176 ) $ —

The Company recognized $3.1 million in compensation expense related to its shares of restricted common stock and the LTIP unit awards for the nine months ended September 30, 2020. As of September 30, 2020, unrecognized compensation expense for both sets of awards was $6.1 million, which will be amortized over the applicable vesting period. A summary of dividends declared by the Company’s board of directors per share of common stock and per common unit at the date of record is as follows: Quarter Declaration Date Record Date Payment Date Dividend (1) Q1 2020 April 29, 2020 May 14, 2020 June 25, 2020 $ 0.26 Q2 2020 July 29, 2020 August 13, 2020 September 11, 2020 $ 0.26 Q3 2020 October 27, 2020 November 11, 2020 December 11, 2020 $ 0.26 (1) Prior to the end of the performance period as set forth in the applicable LTIP unit award, holders of performance-based LTIP units are entitled to receive dividends per LTIP unit equal to 10% of the dividend paid per common unit. 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. 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 to sales made under each of the ATM Program s as of September 30, 2020 (amounts in thousands except share amounts) : March 2019 ATM Program December 2019 ATM Program For the Three Months Ended: Number of Shares Sold (1) Net Proceeds (1) Number of Shares Sold (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 Total 4,120,992 $ 93,774 2,027,191 $ 47,996 (1) As of September 30, 2020, the Company had entered into forward sales transactions under the March 2019 ATM Program and December 2019 ATM Program for the sale of an additional 3,827,455 shares of its common stock that have not yet been settled. Subject to its right to elect net share settlement, the Company expects 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 $25.88 per share, the Company expects to receive net proceeds of approximately $99.1 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. The Company used the net proceeds received from such sales for general corporate purposes. As of September 30, 2020, the Company had approximately $157.9 million of gross sales of its 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. In connection with this acquisition, the Company entered into a tax protection agreement, under which it agreed to indemnify the contributors for any taxes incurred as a result of a taxable sale of such property for a period of four years. The Company also agreed in the tax protection agreement with the contributors to use the “traditional method” of making allocations under Section 704(c) of the Code for the four-year period.

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 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 three and nine months ended September 30, 2020 and 2019 (amounts in thousands, except per share amounts): For the three months ended September 30, For the nine months ended September 30, 2020 2019 2020 2019 Numerator Net income (loss) $ 4,821 $ 603 $ 10,902 $ 6,613 Less: Non-controlling interest in Operating Partnership (557 ) (54 ) (1,275 ) (838 ) Net income (loss) available to Easterly Government Properties, Inc. 4,264 549 9,627 5,775 Less: Dividends on participating securities (72 ) (31 ) (217 ) (88 ) Net income (loss) available to common stockholders $ 4,192 $ 518 $ 9,410 $ 5,687 Denominator for basic EPS 80,334,976 71,444,448 77,144,791 67,010,162 Dilutive effect of share-based compensation awards 51,495 28,530 54,318 14,487 Dilutive effect of LTIP units (1) 537,446 356,013 514,607 308,021 Dilutive effect of shares issuable under forward sales agreements (2) 4,927 — 31,654 — Denominator for diluted EPS 80,928,844 71,828,991 77,745,370 67,332,670 Basic EPS $ 0.05 $ 0.01 $ 0.12 $ 0.08 Diluted EPS $ 0.05 $ 0.01 $ 0.12 $ 0.08 (1) During the three and nine months ended September 30, 2020, there were approximately 74,481 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 three and nine months ended September 30, 2020, there were approximately 3,747,232 and 2,397,232 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 [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 15.8 years 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 . On September 25, 2020, the FDA – Lenexa development project was substantially completed and a 20-year lease commenced with the GSA for the beneficial use of the FDA. Upon completion and their acceptance of work, the U.S. Government is obligated to pay a $41.7 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 September 30, 2020 (amounts in thousands): Payments due by period Total 2020 2021 2022 2023 2024 Thereafter Fixed lease payments $ 1,664,872 49,927 185,658 166,821 156,057 143,438 962,971 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 an expiration date of June 2021. We also lease office space in San Diego, CA under an operating lease that commenced in February 2015 and expires in April 2022. In August 2020, we entered into a lease agreement for office space in Washington, D.C. to replace our existing lease that expires in June 2021. This lease has a commencement date of July 2021 and expiration date of August 2026. Neither of the commenced 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 commenced corporate office leases. As of September 30, 2020, the unamortized balance associated with the Company’s right-of-use operating lease asset and operating lease liability for the Company’s two commenced office leases was $0.5 million. The Company used its incremental borrowing rate, which was arrived at utilizing prevailing market rates and the spread on our 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 commenced operating leases for the three and nine months ended September 30, 2020 and 2019 (amounts in thousands): For the three months ended September 30, For the nine months ended September 30, 2020 2019 2020 2019 Operating leases costs $ 115 $ 115 $ 344 $ 346 In addition, the maturity of fixed lease payments under the Company’s corporate office leases as of September 30, 2020 is summarized in the table below (amounts in thousands): Payments due by period Total 2020 2021 2022 2023 2024 Thereafter Fixed lease payments $ 2,383 125 457 278 312 446 765

Risks And Uncertainties [Abstract]
Concentrations Risk	11. Concentrations Risk Concentrations of credit risk arise for the Company when multiple tenants of the Company are engaged in similar business activities, are located in the same geographic region or have similar economic features that impact in a similar manner their ability to meet contractual obligations, including those to the Company. The Company regularly monitors its tenant base to assess potential concentrations of credit risk. As stated in Note 1 above, the Company leases commercial space to the U.S. Government or non-governmental tenants. At September 30, 2020, the U.S. Government accounted for approximately 98.5% of our total annualized lease income and non-governmental tenants accounted for the remaining approximately 1.5%. Nineteen of our 76 operating properties are located in California, accounting for approximately 19.2% of our total leased square feet and approximately 25.6% of our total annualized lease income as of September 30, 2020. To the extent that weak economic or real estate conditions or natural disasters affect California more severely than other areas of the country, our business, financial condition and results of operations could be significantly impacted.

Accounting Policies [Abstract]
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 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”). The Company 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 the Company’s derivatives consistent with past presentation, therefore, the adoption did not have a material impact on our consolidated financial statements.

[1]	(2) Our revolving credit facility had available capacity of $450.0 million at September 30, 2020 with an accordion feature that permits us to request additional lender commitments for up to $250.0 million of additional capacity, subject to the satisfaction of customary terms and conditions.
[2]	At September 30, 2020, the one-month LIBOR (“L”) was 0.15%. 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 the $450.0 million senior unsecured revolving credit facility (our “revolving credit facility”), the $150.0 million senior unsecured term loan facility (our “2018 term loan facility”) and the $100.0 million senior unsecured term loan facility (our “2016 term loan facility”) is based on the Company’s consolidated leverage ratio, as defined in the respective loan agreements.
[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 2.62% annually, based on the Company’s consolidated leverage ratio, as defined in our 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 3.91% annually, based on the Company’s consolidated leverage ratio, as defined in our 2018 term loan facility agreement.
[6]	Effective interest rates are as follows: DEA – Pleasanton 1.80%, 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%.
