Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Operations	Organization and Operations American Homes 4 Rent (“AH4R” or “General Partner”) is a Maryland real estate investment trust (“REIT”) formed on October 19, 2012 for the purpose of acquiring, developing, renovating, leasing and operating single-family homes as rental properties. American Homes 4 Rent, L.P., a Delaware limited partnership formed on October 22, 2012, and its consolidated subsidiaries (collectively, the “Operating Partnership,” our “operating partnership” or the “OP”) is the entity through which the Company conducts substantially all of our business and owns, directly or through subsidiaries, substantially all of our assets. References to the “Company,” “we,” “our” and “us” mean collectively AH4R, the Operating Partnership and those entities/subsidiaries owned or controlled by AH4R and/or the Operating Partnership. As of March 31, 2020, the Company held 52,776 single-family properties in 22 states, including 960 properties classified as held for sale. AH4R is the general partner of, and as of March 31, 2020 owned approximately 85.2% of the common partnership interest in, the Operating Partnership. The remaining 14.8% of the common partnership interest was owned by limited partners. As the sole general partner of the Operating Partnership, AH4R has exclusive control of the Operating Partnership’s day-to-day management. The Company’s management operates AH4R and the Operating Partnership as one business, and the management of AH4R consists of the same members as the management of the Operating Partnership. AH4R’s primary function is acting as the general partner of the Operating Partnership. The only material asset of AH4R is its partnership interest in the Operating Partnership. As a result, AH4R generally does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing equity from time to time and guaranteeing certain debt of the Operating Partnership. AH4R itself is not directly obligated under any indebtedness, but guarantees some of the debt of the Operating Partnership. The Operating Partnership owns substantially all of the assets of the Company, including the Company’s ownership interests in its joint ventures, either directly or through its subsidiaries, conducts the operations of the Company’s business and is structured as a limited partnership with no publicly traded equity. One difference between the Company and the Operating Partnership is $25.7 million of asset-backed securitization certificates issued by the Operating Partnership and purchased by AH4R. The asset-backed securitization certificates are recorded as an asset-backed securitization certificates receivable by the Company and as an amount due from affiliates by the Operating Partnership. AH4R contributes all net proceeds from its various equity offerings to the Operating Partnership. In return for those contributions, AH4R receives Operating Partnership units (“OP units”) equal to the number of shares it has issued in the equity offering. Based on the terms of the Agreement of Limited Partnership of the Operating Partnership, as amended, OP units can be exchanged for shares on a one-for-one basis. Except for net proceeds from equity issuances by AH4R, the Operating Partnership generates the capital required by the Company’s business through the Operating Partnership’s operations, by the Operating Partnership’s incurrence of indebtedness or through the issuance of OP units.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation The condensed consolidated financial statements are unaudited and include the accounts of AH4R, the Operating Partnership and their consolidated subsidiaries. The condensed consolidated financial statements of the Operating Partnership include the accounts of the Operating Partnership and its consolidated subsidiaries. Intercompany accounts and transactions have been eliminated. The Company consolidates real estate partnerships and other entities that are not variable interest entities (“VIEs”) when it owns, directly or indirectly, a majority interest in the entity or is otherwise able to control the entity. The Company consolidates VIEs in accordance with Accounting Standards Codification (“ASC”) No. 810, Consolidation, if it is the primary beneficiary of the VIE as determined by its power to direct the VIE’s activities and the obligation to absorb its losses or the right to receive its benefits, which are potentially significant to the VIE. Entities for which the Company owns an interest, but does not consolidate, are accounted for under the equity method of accounting as an investment in an unconsolidated subsidiary and are included in escrow deposits, prepaid expenses and other assets within the condensed consolidated balance sheets. The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conjunction with the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. Any references in this report to the number of properties is outside the scope of our independent registered public accounting firm’s review of our financial statements, in accordance with the standards of the Public Company Accounting Oversight Board. In the opinion of management, all adjustments of a normal and recurring nature necessary for a fair statement of the condensed consolidated financial statements for the interim periods have been made. The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Effective March 31, 2020, as a result of the expected growth in our joint venture activities, the investments in unconsolidated joint ventures balance has been reclassified into a separate balance sheet line item. This resulted in the reclassification of $67.9 million as of December 31, 2019, which was previously included in escrow deposits, prepaid expenses and other assets, into investments in unconsolidated joint ventures in the condensed consolidated balance sheets. Certain other amounts in the condensed consolidated financial statements for the prior periods have also been reclassified to conform to the current year presentation. Accounting Pronouncements Adopted January 1, 2020 In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , to amend the accounting for credit losses for certain financial instruments by requiring companies to recognize an estimate of expected credit losses as an allowance in order to recognize such losses more timely than under previous guidance that had allowed companies to wait until it was probable such losses had been incurred. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses , which clarifies that receivables arising from operating leases are not within the scope of Topic 326. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases . In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments , which provides further clarification around some of the amendments in ASU 2016-13. In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments-Credit Losses (Topic 326) Targeted Transition Relief , which provides entities that have certain instruments within the scope of Topic 326 with an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis upon adoption of Topic 326. In November 2019, the FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments—Credit Losses , which provides further clarification around some of the amendments in ASU 2016-13. The guidance is effective for the Company for annual reporting periods beginning after December 15, 2019, and for interim periods within those annual periods. Early adoption is permitted for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. An entity will apply the amendments in these ASUs through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). A prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized before the effective date. The effect of a prospective transition approach is to maintain the same amortized cost basis before and after the effective date of the guidance. The Company adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our financial statements (see Note 6. Escrow Deposits, Prepaid Expenses and Other Assets). In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement , which eliminates, adds and modifies certain disclosure requirements for fair value measurements. Companies will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy. Companies will also be required to disclose the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those annual periods with early adoption permitted. The amendments on the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract , which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). Capitalized implementation costs related to a hosting arrangement that is a service contract will be amortized over the term of the hosting arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. The guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those annual periods with early adoption permitted. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this ASU apply only to contracts, hedging relationships and other transactions that reference the London Inter-Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform but do not apply to contract modifications made or hedging relationships entered into or evaluated after December 31, 2022. The amendments in this ASU allow companies to (i) account for modifications to contracts within the scope of ASC 310, Receivables , and ASC 470, Debt , prospectively by adjusting the effective interest rate and (ii) account for modifications to contracts within the scope of ASC 842, Leases , as a continuation of existing lease agreements. The guidance also provides optional expedients for modifications to contracts within the scope of ASC 815, Derivatives and Hedging . The guidance is effective immediately, and entities may elect to apply the guidance as of January 1, 2020 or the beginning of a subsequent interim period, or prospectively from a date beginning January 1, 2020 or in a subsequent interim period up to the date the financial statements are available to be issued. The Company adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our financial statements. Recent Accounting Pronouncements Not Yet Effective In January 2020, the FASB issued ASU No. 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) , which clarifies the interaction between ASC Topics 321, 323 and 815. ASC 321, Investments—Equity Securities , provides a company with a measurement alternative to measure certain equity securities without a readily determinable fair value at cost, minus impairment, if any. If the company then identifies observable price changes in orderly transactions for the identical or a similar investment of the same issuer, it should measure the equity security at fair value as of the date that the observable transaction occurred. The amendments in this ASU clarify that a company should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with ASC 321 immediately before applying or upon discontinuing the equity method. The amendments in this ASU also clarify the accounting treatment of forward contracts and purchased options for securities that will be accounted for under the equity method of accounting upon settlement or exercise. The guidance is effective for fiscal years beginning after December 15, 2020, and for interim periods within those annual periods with early adoption permitted. The amendments in this ASU should be applied prospectively by applying the amendments at the beginning of the interim period that includes the adoption date. The Company is currently assessing the impact of the guidance on its financial statements.

The secured promissory notes require monthly or quarterly interest payments with the full principal due at maturity. Notes receivable are presented net of discounts, and interest income from the notes, including amortization of discounts, is presented in other revenues within the condensed consolidated statements of operations. Upon adoption of ASU 2016-13 on January 1, 2020 (see Note 2. Significant Accounting Policies), we are required to estimate and recognize lifetime expected losses, rather than incurred losses, on these notes receivable, which results in the earlier recognition of credit losses even if the expected risk of credit loss is remote. An allowance for expected credit losses of $1.5 million was established with a cumulative-effect adjustment to accumulated deficit in the condensed consolidated statements of equity. Notes receivable are presented net of the allowance for expected credit losses, which the Company estimates on a quarterly basis based on (i) credit quality indicators such as the borrower’s historical performance, including the borrower’s financial results and satisfaction of scheduled payments, (ii) current conditions, including macroeconomic conditions and other conditions affecting the borrower, and (iii) other reasonable and supportable forecasts about the future. As part of the monitoring process, we may meet with a borrower’s management to better understand such borrower’s

Equity Method Investments and Joint Ventures [Abstract]
Investments In Unconsolidated Joint Ventures	Investments in Unconsolidated Joint Ventures In February 2020, the Operating Partnership entered into a $253.1 million strategic joint venture with institutional investors advised by J.P. Morgan Asset Management focused on constructing and operating newly built rental homes. The Company holds a 20% ownership interest in the joint venture, which has an evergreen term. Additionally, the Company will earn fees for development and management services provided to the joint venture and have an opportunity to earn a promoted interest after construction and initial operation of the joint venture’s properties. In evaluating the Company’s 20% ownership interest in the joint venture, we concluded that the joint venture is not a variable interest entity after applying the variable interest model and, therefore, we account for our interest in the joint venture as an investment in an unconsolidated subsidiary after applying the voting interest model using the equity method of accounting. Subsequent to March 31, 2020, as contemplated by the joint venture agreement, the parties entered into an amended agreement to increase the size of the partnership to $625.0 million while the other principal terms of the agreement remain the same. The changes to the agreement do not impact the accounting treatment of the joint venture. The Company provides property management and development services to certain unconsolidated joint ventures, which are considered to be related parties. Management fee income from these joint ventures was $0.9 million and $0.7 million for the three months ended March 31, 2020 and 2019, respectively, which were included in other revenues within the condensed consolidated statements of operations.

(4) The stated interest rate on the 2028 unsecured senior notes is 4.25%, which was effectively hedged to yield an interest rate of 4.08%. (5) The revolving credit facility provides for a borrowing capacity of up to $800.0 million and the Company had approximately $3.7 million and $6.2 million committed to outstanding letters of credit that reduced our borrowing capacity as of March 31, 2020 and December 31, 2019, respectively. The revolving credit facility bears interest at LIBOR plus 1.20% as of March 31, 2020. LIBOR is expected to be discontinued after 2021 and the Company expects to replace the contractual reference rate with an appropriate alternative. The Company does not expect this modification to have a material impact on its financial statements. (6) Deferred financing costs relate to our asset-backed securitizations and unsecured senior notes. Amortization of deferred financing costs was $1.5 million for both the three months ended March 31, 2020 and 2019, which was included in gross interest, prior to interest capitalization.

Equity [Abstract]
Shareholders' Equity / Partners' Capital	Shareholders’ Equity / Partners’ Capital When the Company issues common or preferred shares, the Operating Partnership issues an equivalent number of units of partnership interest of a corresponding class to AH4R, with the Operating Partnership receiving the net proceeds from the share issuances. At-the-Market Common Share Offering Program The Company established an at-the-market common share offering program under which we can issue Class A common shares from time to time through various sales agents up to an aggregate of $500.0 million (the “At-the-Market Program”). The Company intends to use any net proceeds from the At-the-Market Program to repay borrowings under the Company’s revolving credit facility, to acquire and renovate single-family properties and for related activities in accordance with the Company’s business strategy, and for working capital and general corporate purposes. The At-the-Market Program may be suspended or terminated by the Company at any time. As of March 31, 2020, no shares have been issued under the At-the-Market Program and $500.0 million remained available for future share issuances. Share Repurchase Program The Company’s board of trustees authorized the establishment of our share repurchase program, authorizing the repurchase of up to $300.0 million of our outstanding Class A common shares and up to $250.0 million of our outstanding preferred shares from time to time in the open market or in privately negotiated transactions. The program does not have an expiration date, but may be suspended or discontinued at any time without notice. All repurchased shares are constructively retired and returned to an authorized and unissued status. The Operating Partnership funds the repurchases and constructively retires an equivalent number of corresponding Class A units. During the three months ended March 31, 2020 and 2019, we did not repurchase and retire any of our shares. As of March 31, 2020, we had a remaining repurchase authorization of up to $265.1 million of our outstanding Class A common shares and up to $250.0 million of our outstanding preferred shares under the program. Preferred Shares As of March 31, 2020 and December 31, 2019, the Company had the following series of preferred shares outstanding (in thousands, except share data): March 31, 2020 December 31, 2019 Series Issuance Date Earliest Redemption Date Dividend Rate Outstanding Shares Current Liquidation Value Outstanding Shares Current Liquidation Value Series D perpetual preferred shares 5/24/2016 5/24/2021 6.500 % 10,750,000 $ 268,750 10,750,000 $ 268,750 Series E perpetual preferred shares 6/29/2016 6/29/2021 6.350 % 9,200,000 230,000 9,200,000 230,000 Series F perpetual preferred shares 4/24/2017 4/24/2022 5.875 % 6,200,000 155,000 6,200,000 155,000 Series G perpetual preferred shares 7/17/2017 7/17/2022 5.875 % 4,600,000 115,000 4,600,000 115,000 Series H perpetual preferred shares 9/19/2018 9/19/2023 6.250 % 4,600,000 115,000 4,600,000 115,000 Total preferred shares 35,350,000 $ 883,750 35,350,000 $ 883,750 Distributions The Company’s board of trustees declared the following distributions during the respective quarters.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	Fair Value The carrying amount of rents and other receivables, restricted cash, escrow deposits, prepaid expenses and other assets, and accounts payable and accrued expenses approximate fair value because of the short maturity of these amounts. Our asset-backed securitizations and revolving credit facility are financial instruments classified as Level 3 in the fair value hierarchy as their fair values were estimated using unobservable inputs. We estimated the fair values of the asset-backed securitizations by modeling the contractual cash flows required under the instruments and discounting them back to their present values using estimates of current market rates. As our revolving credit facility bears interest at a floating rate based on an index plus a spread (see Note 8. Debt), management believes that the carrying value (excluding deferred financing costs) of the revolving credit facility reasonably approximates fair value. Our unsecured senior notes are also financial instruments which are classified as Level 2 in the fair value hierarchy as their fair values were estimated using observable inputs based on the market value of the last trade at the end of the period. The following table displays the carrying values and fair values of our debt instruments as of March 31, 2020 and December 31, 2019 (in thousands): March 31, 2020 December 31, 2019 Carrying Value Fair Value Carrying Value Fair Value AH4R 2014-SFR2 securitization $ 478,742 $ 489,685 $ 479,706 $ 491,302 AH4R 2014-SFR3 securitization 493,774 508,650 495,029 510,486 AH4R 2015-SFR1 securitization 518,530 532,012 519,576 534,531 AH4R 2015-SFR2 securitization 449,823 466,022 450,733 466,558 Total asset-backed securitizations 1,940,869 1,996,369 1,945,044 2,002,877 2028 unsecured senior notes, net 493,786 508,780 493,589 531,870 2029 unsecured senior notes, net 395,005 392,100 394,864 446,728 Total unsecured senior notes, net 888,791 900,880 888,453 978,598 Revolving credit facility 105,000 105,000 — — Total debt $ 2,934,660 $ 3,002,249 $ 2,833,497 $ 2,981,475

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events COVID-19 Pandemic Subsequent to March 31, 2020, the global economy has continued to be severely impacted by the COVID-19 pandemic. We are actively monitoring the impact of the COVID-19 pandemic, which we anticipate will negatively impact our business and results of operations for our second fiscal quarter and likely beyond. The extent to which our operations will be impacted will depend largely on future developments, which are highly uncertain and cannot be accurately predicted, including new information which may emerge concerning the severity of the pandemic and actions by government authorities to contain the pandemic or treat its impact, among other things. Subsequent Acquisitions From April 1, 2020 through April 30, 2020, the Company added 158 properties to its portfolio for a total cost of approximately $39.2 million, which included 143 homes developed through our new construction channel. Subsequent Dispositions From April 1, 2020 through April 30, 2020, the Company disposed of 60 properties for aggregate net proceeds of approximately $13.8 million.

Accounting Policies [Abstract]
Basis of Presentation	The condensed consolidated financial statements are unaudited and include the accounts of AH4R, the Operating Partnership and their consolidated subsidiaries. The condensed consolidated financial statements of the Operating Partnership include the accounts of the Operating Partnership and its consolidated subsidiaries. Intercompany accounts and transactions have been eliminated. The Company consolidates real estate partnerships and other entities that are not variable interest entities (“VIEs”) when it owns, directly or indirectly, a majority interest in the entity or is otherwise able to control the entity. The Company consolidates VIEs in accordance with Accounting Standards Codification (“ASC”) No. 810, Consolidation, if it is the primary beneficiary of the VIE as determined by its power to direct the VIE’s activities and the obligation to absorb its losses or the right to receive its benefits, which are potentially significant to the VIE. Entities for which the Company owns an interest, but does not consolidate, are accounted for under the equity method of accounting as an investment in an unconsolidated subsidiary and are included in escrow deposits, prepaid expenses and other assets within the condensed consolidated balance sheets. Board. In the opinion of management, all adjustments of a normal and recurring nature necessary for a fair statement of the condensed consolidated financial statements for the interim periods have been made. The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Effective March 31, 2020, as a result of the expected growth in our joint venture activities, the investments in unconsolidated joint ventures balance has been reclassified into a separate balance sheet line item. This resulted in the reclassification of $67.9 million as of December 31, 2019, which was previously included in escrow deposits, prepaid expenses and other assets, into investments in unconsolidated joint ventures in the condensed consolidated balance sheets. Certain other amounts in the condensed consolidated financial statements for the prior periods have also been reclassified to conform to the current year presentation.
Recent Accounting Pronouncements	In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , to amend the accounting for credit losses for certain financial instruments by requiring companies to recognize an estimate of expected credit losses as an allowance in order to recognize such losses more timely than under previous guidance that had allowed companies to wait until it was probable such losses had been incurred. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses , which clarifies that receivables arising from operating leases are not within the scope of Topic 326. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases . In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments , which provides further clarification around some of the amendments in ASU 2016-13. In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments-Credit Losses (Topic 326) Targeted Transition Relief , which provides entities that have certain instruments within the scope of Topic 326 with an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis upon adoption of Topic 326. In November 2019, the FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments—Credit Losses , which provides further clarification around some of the amendments in ASU 2016-13. The guidance is effective for the Company for annual reporting periods beginning after December 15, 2019, and for interim periods within those annual periods. Early adoption is permitted for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. An entity will apply the amendments in these ASUs through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). A prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized before the effective date. The effect of a prospective transition approach is to maintain the same amortized cost basis before and after the effective date of the guidance. The Company adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our financial statements (see Note 6. Escrow Deposits, Prepaid Expenses and Other Assets). In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement , which eliminates, adds and modifies certain disclosure requirements for fair value measurements. Companies will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy. Companies will also be required to disclose the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those annual periods with early adoption permitted. The amendments on the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract , which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). Capitalized implementation costs related to a hosting arrangement that is a service contract will be amortized over the term of the hosting arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. The guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those annual periods with early adoption permitted. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this ASU apply only to contracts, hedging relationships and other transactions that reference the London Inter-Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform but do not apply to contract modifications made or hedging relationships entered into or evaluated after December 31, 2022. The amendments in this ASU allow companies to (i) account for modifications to contracts within the scope of ASC 310, Receivables , and ASC 470, Debt , prospectively by adjusting the effective interest rate and (ii) account for modifications to contracts within the scope of ASC 842, Leases , as a continuation of existing lease agreements. The guidance also provides optional expedients for modifications to contracts within the scope of ASC 815, Derivatives and Hedging . The guidance is effective immediately, and entities may elect to apply the guidance as of January 1, 2020 or the beginning of a subsequent interim period, or prospectively from a date beginning January 1, 2020 or in a subsequent interim period up to the date the financial statements are available to be issued. The Company adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our financial statements. Recent Accounting Pronouncements Not Yet Effective In January 2020, the FASB issued ASU No. 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) , which clarifies the interaction between ASC Topics 321, 323 and 815. ASC 321, Investments—Equity Securities , provides a company with a measurement alternative to measure certain equity securities without a readily determinable fair value at cost, minus impairment, if any. If the company then identifies observable price changes in orderly transactions for the identical or a similar investment of the same issuer, it should measure the equity security at fair value as of the date that the observable transaction occurred. The amendments in this ASU clarify that a company should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with ASC 321 immediately before applying or upon discontinuing the equity method. The amendments in this ASU also clarify the accounting treatment of forward contracts and purchased options for securities that will be accounted for under the equity method of accounting upon settlement or exercise. The guidance is effective for fiscal years beginning after December 15, 2020, and for interim periods within those annual periods with early adoption permitted. The amendments in this ASU should be applied prospectively by applying the amendments at the beginning of the interim period that includes the adoption date. The Company is currently assessing the impact of the guidance on its financial statements.
