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, 2018, 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, 2018 filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 28, 2019. 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. As of September 30, 2019, we wholly owned 68 operating properties in the United States that were 100% leased, including 66 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 6.3 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 88.4% of the aggregate limited partnership interests in the Operating Partnership (“common units”) at September 30, 2019. We believe that we have operated and have been organized in conformity with the requirements for qualification and taxation as a REIT for U.S. federal income tax purposes commencing with our taxable year ended December 31, 2015. Principles of Consolidation The accompanying consolidated financial statements are presented on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company, 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, 2019, and the consolidated results of operations for the three and nine months ended September 30, 2019 and 2018 and the consolidated cash flows for the nine months ended September 30, 2019 and 2018. 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. Actual results could differ from those estimates.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies See below for the Company’s revenue recognition policy subsequent to the adoption of Accounting Standards Update (“ASU”) 2016-02, Leases discussed below. All other 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, 2018. 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 the closing of the property. Lease incentives are recorded as a deferred asset and amortized as a reduction of rental income 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. 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. Reclassifications and New Accounting Standards Certain prior year amounts have been reclassified to conform to the current year presentation. Amounts previously classified as tenant reimbursements which qualified for the practical expedient and were determined to be lease components have been reclassified to rental income to conform with current period presentation. Recently Adopted Accounting Standards In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2016-02, Leases, along with various subsequent ASUs, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for in the same manner as the previous guidance for operating leases. The Company adopted ASU 2016-02 on January 1, 2019, using the modified retrospective transition method such that we applied the standard as of the adoption date. Going forward, ASU 2016-02, will also require that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. Under ASU 2016-02, allocated payroll costs and other costs that are incurred regardless of whether the lease is obtained will no longer be capitalized as initial direct costs and instead will be expensed as incurred within Corporate general and administrative expense on the Company's Consolidated Statements of Operations. Additionally, in July 2018, the FASB issued ASU 2018-11, Target Improvements to Topic 842 Leases. ASU 2018-11 provides lessors a practical expedient to not separate nonlease components from the associated lease component if the timing and pattern of transfer for the lease and nonlease components are the same and if the lease component, if accounted for separately, would be classified as an operating lease. Lease components are elements of an arrangement that provide the customer with the right to use an identified asset. Nonlease components are distinct elements of a contract that are not related to securing the use of the leased asset and revenue is recognized in accordance with Accounting Standards Codification Topic 606 , Revenue from Contracts and Customers (“ ASC 606 ”) . The Company assessed and concluded that the timing and pattern of transfer for nonlease components and the associated lease component are the same. The Company determined that the predominant component was the lease component and as such the Company has made a policy election to account for and present the lease component and the nonlease component as a single component in the revenue section of the Consolidated Statements of Operations. While application of the practical expedient did not result in a material change to the recognition of rental income, nonlease components included within Tenant reimbursement prior to the adoption of Accounting Standards Codification Topic 842 , Leases (“ASC 842”) are now included within Rental income on the Company's Consolidated Statements of Operations. In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842): Codification Improvements which amended the transition guidance in ASC 842 to explicitly exempt entities from the interim disclosures required by Accounting Standards Codification Topic ASC 205, Presentation of Financial Statements, related to changes in accounting principles. The provision is applicable at the time that entities adopt ASC 842, however implementation of this update did not have a material impact on our consolidated financial statements. The adoption of this standard also resulted in a cumulative effect adjustment of less than $0.1 million recorded as a decrease to Retained earnings as of January 1, 2019 in the accompanying Consolidated Statements of Equity. The cumulative effect adjustment related to initial direct costs of leases where the Company is the lessor that, as of January 1, 2019, had not begun to amortize and therefore are no longer allowed to be capitalized under the new standard. Additionally, as of January 1, 2019, the Company recognized an operating lease right-of-use asset and related operating lease liability of approximately $1.3 million on the accompanying Consolidated Balance Sheets, related to the leases where the Company is the lessee. The lease liability associated with these leases is reflected on the Company’s Consolidated Balance Sheet within Accounts payable and accrued liabilities and the right-of-use asset is included within Prepaid expenses and other assets. Associated lease expense will be recognized on a straight-line basis over the expected lease term based on the total lease payments and is included within Corporate general and administrative expense in the . On January 1, 2019, the Company adopted ASU 2017-12 (Topic 815), Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The Company adopted this ASU using the modified retrospective method and the adoption did not have a material impact on our consolidated financial statements.

Private Placement of Senior Unsecured Notes On September 12, 2019, the Operating Partnership issued an aggregate of $275.0 million of fixed rate, senior unsecured notes (the “Notes”) in a private placement pursuant to a purchase agreement among the Operating Partnership, the Company and the purchasers of the Notes dated July 30, 2019 (the “Purchase Agreement”). The Notes consist of (i) 3.73% Series A Senior Notes due September 12, 2029 in an aggregate principal amount of $85.0 million, (ii) 3.83% Series B Senior Notes due September 12, 2031 in an aggregate principal amount of $100.0 million, and (iii) 3.98% Series C Senior Notes due September 12, 2034 in an aggregate principal amount of $90.0 million.

As of September 30, 2019, the carrying value of our 2016 term loan facility approximated fair value. In determining the fair value we considered the variable interest rate and credit spreads. We deem the fair value of our 2016 term loan facility as a Level 3 measurement. As of September 30, 2019, the carrying value of our 2018 term loan facility approximated fair value. In determining the fair value we considered the variable interest rate and credit spreads. We deem the fair value of our 2018 term loan facility as a Level 3 measurement. As of September 30, 2019, the fair value of our senior unsecured notes payable was determined by discounting future contractual principal and interest payments using prevailing market rates. We deem the fair value measurement of our senior unsecured notes payable instruments as a Level 3 measurement. At September 30, 2019 , the fair value of our senior unsecured notes payable was $ million. As of September 30, 2019, the fair value of our mortgage notes payable was determined by discounting future contractual principal and interest payments using prevailing market rates. We deem the fair value measurement of our mortgage notes payable instruments as a Level 3 measurement. At September 30, 2019, the fair value of our mortgage notes payable was $212.8 .

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, 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 September 30, 2019, aggregated by the level in the fair value hierarchy within which those measurements fall (amounts in thousands): As of September 30, 2019 Balance Sheet Line Item Level 1 Level 2 Level 3 Interest rate swaps - Asset $ — $ — $ — Interest rate swaps - Liability $ — $ (7,232 ) $ —

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, 2019 and 2018 (amounts in thousands, except per share amounts): For the three months ended September 30, For the nine months ended September 30, 2019 2018 2019 2018 Numerator Net income $ 603 $ 2,482 $ 6,613 $ 6,016 Less: Non-controlling interest in Operating Partnership (54 ) (327 ) (838 ) (902 ) Net income available to Easterly Government Properties, Inc. 549 2,155 5,775 5,114 Less: Dividends on participating securities (31 ) (281 ) (88 ) (842 ) Net income available to common stockholders $ 518 $ 1,874 $ 5,687 $ 4,272 Denominator for basic EPS 71,444,448 60,446,199 67,010,162 51,051,388 Dilutive effect of share-based compensation awards 28,530 6,204 14,487 8,867 Dilutive effect of LTIP units (1) 356,013 1,012,448 308,021 1,172,676 Dilutive effect of shares issuable under forward sales agreements — 514,147 — 367,927 Denominator for diluted EPS 71,828,991 61,978,998 67,332,670 52,600,858 Basic EPS $ 0.01 $ 0.03 $ 0.08 $ 0.08 Diluted EPS $ 0.01 $ 0.03 $ 0.08 $ 0.08 (1) During the three and nine months ended September 30, 2018, there were approximately 173,381 unvested performance-based LTIP units that were not included in the computation of diluted earnings per share because to do so would have been antidilutive for the period.

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 16.1 years as of September 30, 2019), the mission-critical focus of the properties subject to the leases and the current level of operations at such properties. Certain lease agreements include variable lease payments that, in the future, will vary based on changes in inflationary measures, real estate tax rates, usage, or share of expenditures of the leased premises . As discussed above in Note 2, the Company elected a practical expedient to not separate nonlease components from the associated lease component if the time and pattern of transfer for the lease and nonlease components are the same and if the lease component, if accounted for separately, would be classified as an operating lease. On August 27, 2019, the FDA – Alameda development project was substantially completed and a 20-year non-cancelable lease commenced with the GSA for the beneficial use of the Food and Drug Administration (“FDA”). Upon completion and their acceptance of work, the U.S. Government paid a $52.5 million lump sum reimbursement to the Company for landlord improvements in excess of the U.S. Government’s tenant improvement allowance. The Company recorded the payment as Deferred revenue on the Consolidated Balance Sheet and began amortizing the amount over the life of the lease through Rental income. The following table summarizes the maturity of fixed lease payments under the Company’s leases as of September 30, 2019 (amounts in thousands): Payments due by period Total 2019 2020 2021 2022 2023 Thereafter Fixed lease payments $ 1,494,995 45,070 171,863 149,075 133,316 125,199 870,472 Prior to the adoption of ASC 842 on January 1, 2019, the Company’s leases associated with its operating properties fell under the guidance of Accounting Standard Codification Topic ASC 840, Leases (“ASC 840”). As of December 31, 2018, the future non-cancelable minimum contractual rent payments on our operating properties were as follows (amounts in thousands): Payments due by period Total 2019 2020 2021 2022 2023 Thereafter Operating Leases Minimum lease payments $ 1,251,546 151,152 139,315 116,827 99,822 92,392 652,038 Lessee In October 2015, we entered into a sublease agreement for office space in Washington, D.C. with a commencement date of March 2016 and expiration date of June 2021. We also lease office space in San Diego, CA under an operating lease that commenced February 2015 and expires in April 2022. Neither of the leases contain extension options, however they do include variable lease payments that, in the future, will vary based on changes in real estate tax rates, usage, or share of expenditures of the leased premises. The Company has elected not to separate lease and nonlease components for both corporate office leases. As of September 30, 2019, the unamortized balance associated with the Company’s right-of-use operating lease asset and operating lease liability for the Company’s two office leases was $1.0 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 and nine months ended September 30, 2019 (amounts in thousands): For the three months ended September 30, 2019 For the nine months ended September 30, 2019 Operating leases costs $ 115 $ 346 Other Information Weighted average remaining lease terms (in years) 2.14 Weighted average discount rate 3.84% In addition, the maturity of fixed lease payments under the Company’s corporate office leases as of September 30, 2019 is summarized in the table below (amounts in thousands): Payments due by period Total 2019 2020 2021 2022 2023 Thereafter Fixed lease payments $ 1,034 121 496 352 65 — — Prior to the adoption of ASC 842 on January 1, 2019, the Company’s corporate office leases fell under the guidance of ASC 840.

The duration of the majority of tenant construction project reimbursement arrangements are less than a year and payment is typically due once a project is complete and work has been accepted by the tenant. There were no projects ongoing as of September 30, 2019 with a duration of greater than one year. During the three and nine months ended September 30, 2019, the Company also recognized $0.3 million and $0.7 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 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. Less than $0.1 million in parking garage income was generated during the three and nine months ended September 30, 2018. The balance in Accounts receivable related to parking garage income was $0.1 million as of September 30, 2019 and less than $0.1 million as of December 31, 2018. Additionally, the Company also earns credits on its utility bills at certain properties for the use of energy efficient building materials, which also 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 $0.1 million in energy credit income during both the three and nine months ended September 30, 2019 and less than $0.1 million in energy credit income during both the three and nine months ended September 30, 2018. There were no contract assets or liabilities as of September 30, 2019.

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 September 30, 2019, the U.S. Government accounted for approximately 98.2% of rental income and non-governmental tenants accounted for the remaining approximately 1.8%. Seventeen of our 68 operating properties are located in California, accounting for approximately 19.9% of our total rentable square feet and approximately 26.4% of our total annualized lease income as of September 30, 2019. 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.

On October 22, 2019, the Company acquired a 66,818 square foot U.S. Citizenship and Immigration Services facility in Tustin, California. The building was originally constructed in 1979 and fully renovated in 2019. The facility is 100% leased to the GSA pursuant to a 15-year lease, which expires in June 2034.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2019
Accounting Policies [Abstract]
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 the closing of the property. Lease incentives are recorded as a deferred asset and amortized as a reduction of rental income 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. 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.
Reclassifications and New Accounting Standards	Reclassifications and New Accounting Standards Certain prior year amounts have been reclassified to conform to the current year presentation. Amounts previously classified as tenant reimbursements which qualified for the practical expedient and were determined to be lease components have been reclassified to rental income to conform with current period presentation.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2016-02, Leases, along with various subsequent ASUs, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for in the same manner as the previous guidance for operating leases. The Company adopted ASU 2016-02 on January 1, 2019, using the modified retrospective transition method such that we applied the standard as of the adoption date. Going forward, ASU 2016-02, will also require that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. Under ASU 2016-02, allocated payroll costs and other costs that are incurred regardless of whether the lease is obtained will no longer be capitalized as initial direct costs and instead will be expensed as incurred within Corporate general and administrative expense on the Company's Consolidated Statements of Operations. Additionally, in July 2018, the FASB issued ASU 2018-11, Target Improvements to Topic 842 Leases. ASU 2018-11 provides lessors a practical expedient to not separate nonlease components from the associated lease component if the timing and pattern of transfer for the lease and nonlease components are the same and if the lease component, if accounted for separately, would be classified as an operating lease. Lease components are elements of an arrangement that provide the customer with the right to use an identified asset. Nonlease components are distinct elements of a contract that are not related to securing the use of the leased asset and revenue is recognized in accordance with Accounting Standards Codification Topic 606 , Revenue from Contracts and Customers (“ ASC 606 ”) . The Company assessed and concluded that the timing and pattern of transfer for nonlease components and the associated lease component are the same. The Company determined that the predominant component was the lease component and as such the Company has made a policy election to account for and present the lease component and the nonlease component as a single component in the revenue section of the Consolidated Statements of Operations. While application of the practical expedient did not result in a material change to the recognition of rental income, nonlease components included within Tenant reimbursement prior to the adoption of Accounting Standards Codification Topic 842 , Leases (“ASC 842”) are now included within Rental income on the Company's Consolidated Statements of Operations. In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842): Codification Improvements which amended the transition guidance in ASC 842 to explicitly exempt entities from the interim disclosures required by Accounting Standards Codification Topic ASC 205, Presentation of Financial Statements, related to changes in accounting principles. The provision is applicable at the time that entities adopt ASC 842, however implementation of this update did not have a material impact on our consolidated financial statements. The adoption of this standard also resulted in a cumulative effect adjustment of less than $0.1 million recorded as a decrease to Retained earnings as of January 1, 2019 in the accompanying Consolidated Statements of Equity. The cumulative effect adjustment related to initial direct costs of leases where the Company is the lessor that, as of January 1, 2019, had not begun to amortize and therefore are no longer allowed to be capitalized under the new standard. Additionally, as of January 1, 2019, the Company recognized an operating lease right-of-use asset and related operating lease liability of approximately $1.3 million on the accompanying Consolidated Balance Sheets, related to the leases where the Company is the lessee. The lease liability associated with these leases is reflected on the Company’s Consolidated Balance Sheet within Accounts payable and accrued liabilities and the right-of-use asset is included within Prepaid expenses and other assets. Associated lease expense will be recognized on a straight-line basis over the expected lease term based on the total lease payments and is included within Corporate general and administrative expense in the . On January 1, 2019, the Company adopted ASU 2017-12 (Topic 815), Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The Company adopted this ASU using the modified retrospective method and the adoption did not have a material impact on our consolidated financial statements.
