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 March 31, 2020, we wholly owned 72 operating properties in the United States that were 100% leased, including 70 operating properties that were leased primarily to U.S. Government tenant agencies and two operating properties that were entirely leased to private tenants, encompassing approximately 6.8 million square feet in the aggregate. The Operating Partnership holds substantially all of our assets and conducts substantially all of our business. The Company is the sole general partner of the Operating Partnership. The Company owned approximately 87.7% of the aggregate limited partnership interests in the Operating Partnership (“common units”) at March 31, 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 March 31, 2020, and the consolidated results of operations for the three months ended March 31, 2020 and 2019 and the consolidated cash flows for the three months ended March 31, 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.

Real Estate and Intangibles Acquisitions During the three months ended March 31, 2020, we acquired two operating properties in asset acquisitions, consisting of DHA – Aurora and FBI / DEA – El Paso for an aggregate purchase price of $51.6 million.

Amounts reported in Accumulated other comprehensive income (loss) related to derivatives designated as qualifying cash flow hedges will be reclassified to interest expense as interest payments are made on the Company's variable rate debt. The Company estimates that $4.7 million will be reclassified from Accumulated other comprehensive income (loss) 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 March 31, 2020 2019 Unrealized loss recognized in AOCI $ (10,241 ) $ (2,825 ) Gain (loss) reclassified from AOCI into interest expense (395 ) 192 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 March 31, 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 $15.7 million. As of March 31, 2020, the Company had not breached the provisions of these agreements and has not posted any collateral related to these agreements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	6. Fair Value Measurements Accounting standards define fair value as the exit price, or the amount that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standards also establish a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of us. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The hierarchy of these inputs is broken down into three levels: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Categorization within the valuation hierarchy is based upon the lowest level of input that is most significant to the fair value measurement. Recurring fair value measurements The fair values of our interest rate swaps are determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities in such interest rates. While the Company determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. The Company has determined that the significance of the impact of the credit valuation adjustments made to its derivative contracts, which determination was based on the fair value of each individual contract, was not significant to the overall valuation. As a result, all of the Company’s derivatives held as of March 31, 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 March 31, 2020, aggregated by the level in the fair value hierarchy within which those measurements fall (amounts in thousands): As of March 31, 2020 Balance Sheet Line Item Level 1 Level 2 Level 3 Interest rate swaps - Asset $ — $ — $ — Interest rate swaps - Liability $ — $ (15,142 ) $ —

Fifty percent of the LTIP units that are subject to the Company’s total shareholder return performance will vest when earned following the end of the performance period and 50% of the earned award will vest on January 2, 2024, subject to the grantee’s continued employment and the other terms of the awards. All of the LTIP units subject to the Company’s operational performance will vest when earned. On January 3, 2020, the Company also granted an aggregate of 89,242 service-based LTIP units to members of management pursuant to the 2015 Equity Incentive Plan, which will vest on December 31, 2022, subject to the grantee’s continued employment and the other terms of the awards. On March 23, 2020, the Company issued an aggregate of 2,905 shares of restricted common stock to certain employees pursuant to the 2015 Equity Incentive Plan. The shares of restricted common stock will vest upon the second anniversary of the grant date so long as the grantee remains an employee of the Company on such date. A summary of the Company’s shares of restricted common stock and LTIP unit awards at March 31, 2020 is as follows: Restricted Shares Restricted Shares Weighted Average Grant Date Fair Value Per Share LTIP Units (1) LTIP Units Weighted Average Grant Date Fair Value Per Share Outstanding, December 31, 2019 92,197 $ 17.55 284,471 $ 18.66 Granted 2,905 23.06 235,441 21.17 Vested — — (27,732 ) 18.34 Forfeited — — — — Outstanding, March 31, 2020 95,102 $ 17.72 492,180 $ 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. The Company recognized $1.0 million in compensation expense related to its shares of restricted common stock and the LTIP unit awards for the three months ended March 31, 2020. As of March 31, 2020, unrecognized compensation expense for both sets of awards was $7.7 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 (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 March 4, 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 (collectively, the “Sales Agents”) pursuant to which it may issue and sell shares of its common stock having an aggregate offering price of up to $200.0 million from time to time (the “March 2019 ATM Program”) 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”). Under the March 2019 ATM Program, 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 (collectively, the “Forward Counterparties”) for the sale of shares of its common stock on a forward basis. On December 20, 2019, the Company entered into separate new equity distribution agreements with each of the Sales Agents pursuant to which it may issue and sell shares of its common stock having an aggregate offering price of up to $300.0 million from time to time (the “December 2019 ATM Program”) in negotiated transactions or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act. Under the December 2019 ATM Program, the Company may also enter into one or more forward transactions under separate master forward sale confirmations and related supplemental confirmations with each of the Forward Counterparties for the sale of shares of its common stock on a forward basis. No sales of shares of the Company’s common stock were made under the December 2019 ATM Program during the three months ended March 31, 2020. The following table sets forth certain information with respect to sales made under the March 2019 ATM Program as of March 31, 2020 (amounts in thousands except share amounts): March 2019 ATM Program For the Three Months Ended: Number of Shares Sold (1) Net Proceeds (1) March 31, 2020 200,000 $ 4,835 (1) As of March 31, 2020, the Company had entered into forward sales transactions under the March 2019 ATM Program for the sale of an additional 3,402,100 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 certain dates between November 2020 and March 2021. Assuming the forward sales transactions are physically settled in full utilizing a net weighted average initial forward sales price of $22.91 per share, the Company expects to receive net proceeds of approximately $78.0 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 March 31, 2020, the Company had approximately $99.0 million and $300.0 million of gross sales of its common stock available under the March 2019 ATM Program and the December 2019 ATM Program, respectively. 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 months ended March 31, 2020 and 2019 (amounts in thousands, except per share amounts): For the three months ended March 31, 2020 2019 Numerator Net income (loss) $ 1,918 $ (481 ) Less: Non-controlling interest in Operating Partnership (221 ) 65 Net income (loss) available to Easterly Government Properties, Inc. 1,697 (416 ) Less: Dividends on participating securities (57 ) (28 ) Net income (loss) available to common stockholders $ 1,640 $ (444 ) Denominator for basic EPS 74,892,711 61,225,926 Dilutive effect of share-based compensation awards (1) 58,048 — Dilutive effect of LTIP units (2) 471,346 — Dilutive effect of shares issuable under forward sales agreements (3) 194,128 — Denominator for diluted EPS 75,616,233 61,225,926 Basic EPS $ 0.02 $ (0.01 ) Diluted EPS $ 0.02 $ (0.01 ) (1) During the three months ended March 31, 2019, there were approximately 78,449 unvested shares of restricted common stock 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 months ended March 31, 2020 and 2019, there were approximately 43,424 and 284,471 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. (3) During the three months ended March 31, 2020 and 2019, there were approximately 523,397 and 300,000 shares of underlying unsettled forward sales transactions, respectively, 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 [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 15.1 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 January 15, 2020, in connection with the FDA-Lenexa development project, the U.S. Government paid a $20.5 million lump sum reimbursement to the Company which was a progress payment 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 will begin amortizing the amount over the life of the lease through Rental income upon lease commencement. The following table summarizes the maturity of fixed lease payments under the Company’s leases as of March 31, 2020 (amounts in thousands): Payments due by period Total 2020 2021 2022 2023 2024 Thereafter Fixed lease payments $ 1,517,197 138,823 163,340 146,119 136,885 124,139 807,891 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. Neither of the leases contain extension options, however they do include variable lease payments that, in the future, will vary based on changes in real estate tax rates, usage, or share of expenditures of the leased premises. The Company has elected not to separate lease and nonlease components for both corporate office leases. As of March 31, 2020, the unamortized balance associated with the Company’s right-of-use operating lease asset and operating lease liability for the Company’s two office leases was $0.7 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 operating leases for the three months ended March 31, 2020 and 2019 (amounts in thousands): Three Months Ended March 31, 2020 2019 Operating leases costs $ 115 $ 116 In addition, the maturity of fixed lease payments under the Company’s corporate office leases as of March 31, 2020 is summarized in the table below (amounts in thousands): Payments due by period Total 2020 2021 2022 2023 2024 Thereafter Fixed lease payments $ 792 375 352 65 — — —

The duration of the majority of tenant construction project reimbursement arrangements are less than a year and payment is typically due once a project is complete and work has been accepted by the tenant. There were no projects ongoing as of March 31, 2020 with a duration of greater than one year. During the three months ended March 31, 2020 and 2019, the Company also recognized $0.3 million and $0.2 million, respectively, in parking garage income generated from the operations of parking garages situated on the Various GSA - Buffalo property acquired in the third quarter of 2018 and on the Various GSA - Portland property acquired in the first quarter of 2019. The monthly and transient daily parking revenue falls within the scope of Revenue from Contracts with Customers (“ASC 606”) and is accounted for at the point in time when control of the goods or services transfers to the customer and the Company’s performance obligation is satisfied. The balance in Accounts receivable related to parking garage income was $0.1 million as of both March 31, 2020 and December 31, 2019. Additionally, the Company also earns credits on its utility bills at certain properties for the use of energy efficient building materials, which also fall within the scope of ASC 606. The pattern of recognition for the credits is in line with the recognition of the associated utility expense. The Company recognized less than $0.1 million in energy credit income during both the three months ended March 31, 2020 and 2019. There were no contract assets or liabilities as of March 31, 2020.

Concentrations Risk

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 nongovernmental tenants. At March 31, 2020, the U.S. Government accounted for approximately 98.3% of rental income and non-governmental tenants accounted for the remaining approximately 1.7%. Eighteen of our 72 operating properties are located in California, accounting for approximately 19.7% of our total rentable square feet and approximately 26.3% of our total annualized lease income as of March 31, 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.
