Organization and Basis of Presentation

AvalonBay Communities, Inc. (the “Company,” which term, unless the context otherwise requires, refers to AvalonBay Communities, Inc. together with its subsidiaries), is a Maryland corporation that has elected to be treated as a real estate investment trust (“REIT”) for federal income tax purposes under the Internal Revenue Code of 1986 (the “Code”). The Company focuses on the development, redevelopment, acquisition, ownership and operation of multifamily communities primarily in New England, the New York/New Jersey metro area, the Mid-Atlantic, the Pacific Northwest, and Northern and Southern California, as well as in the Company's expansion markets in Southeast Florida and Denver, Colorado (the "Expansion Markets").

At December 31, 2020, the Company owned or held a direct or indirect ownership interest in 273 operating apartment communities containing 80,094 apartment homes in 11 states and the District of Columbia. In addition, the Company owned or held a direct or indirect ownership interest in 18 communities under development that are expected to contain an aggregate of 5,931 apartment homes (unaudited) when completed, as well as The Park Loggia, which contains 172 for-sale residential condominiums, of which 70 have been sold as of December 31, 2020, and 66,000 square feet of commercial space, of which 69% has been leased as of December 31, 2020. The Company also owned or held a direct or indirect ownership interest in land or rights to land on which the Company expects to develop an additional 24 communities that, if developed as expected, will contain an estimated 7,853 apartment homes (unaudited).

Capitalized terms used without definition have meanings provided elsewhere in this Form 10-K.

Principles of Consolidation

The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, certain joint venture partnerships, subsidiary partnerships structured as DownREITs and any variable interest entities that qualify for consolidation. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company accounts for joint venture entities and subsidiary partnerships in accordance with the consolidation guidance. The Company evaluates the partnership of each joint venture entity and determines first whether to follow the variable interest entity (“VIE”) or the voting interest entity (“VOE”) model. Once the appropriate consolidation model is identified, the Company then evaluates whether it should consolidate the venture. Under the VIE model, the Company consolidates an investment when it has control to direct the activities of the venture and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Under the VOE model, the Company consolidates an investment when 1) it controls the investment through ownership of a majority voting interest if the investment is not a limited partnership or 2) it controls the investment through its ability to remove the other partners in the investment, at its discretion, when the investment is a limited partnership.

The Company generally uses the equity method of accounting for its investment in joint ventures, including when the Company holds a noncontrolling limited partner interest in a joint venture. Any investment in excess of the Company's cost basis at acquisition or formation of an equity method venture, will be recorded as a component of the Company's investment in the joint venture and recognized over the life of the underlying fixed assets of the venture as a reduction to its equity in income from the venture. Investments in which the Company has little or no influence are accounted for using the cost method.
Real Estate

Operating real estate assets are stated at cost and consist of land and improvements, buildings and improvements, furniture, fixtures and equipment, and other costs incurred during their development, redevelopment and acquisition. Significant expenditures which improve or extend the life of an existing asset and that will benefit the Company for periods greater than a year, are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred.

Project costs related to the development, construction and redevelopment of real estate projects (including interest and related loan fees, property taxes and other direct costs) are capitalized as a cost of the project. Indirect project costs that relate to several projects are capitalized and allocated to the projects to which they relate. Indirect costs not clearly related to development, construction and redevelopment activity are expensed as incurred. For development, capitalization (i) begins when the Company has determined that development of the future asset is probable, (ii) can be suspended if there is no current development activity underway, but future development is still probable and (iii) ends when the asset, or a portion of an asset, is delivered and is ready for its intended use, or the Company's intended use changes such that capitalization is no longer appropriate.

For land parcels improved with operating real estate, for which the Company intends to pursue development, the Company generally manages the current improvements until such time as all tenant obligations have been satisfied or eliminated through negotiation, and construction of new apartment communities is ready to begin. Revenue from incidental operations received from the current improvements on land parcels in excess of any incremental costs are recorded as a reduction of total capitalized costs of the respective Development Right and not as part of net income. Incidental operating costs in excess of incidental operating income are expensed in the period incurred.

For redevelopment efforts, the Company capitalizes costs either (i) in advance of taking homes out of service when significant renovation of the common area has begun until the redevelopment is completed, or (ii) when an apartment home is taken out of service for redevelopment until the redevelopment is completed and the apartment home is available for a new resident. Rental income and operating costs incurred during the initial lease-up or post-redevelopment lease-up period are recognized in earnings as incurred.

The Company assesses acquisitions of operating communities to determine if it meets the definition of a business or if it qualifies as an asset acquisition. The Company generally views acquisitions of individual operating communities as asset acquisitions, which results in the capitalization of acquisition costs and the allocation of purchase price to the assets acquired and liabilities assumed, based on the relative fair value of the respective assets and liabilities.

The purchase price allocation to tangible assets is reflected in real estate assets and depreciated over their estimated useful lives. Any purchase price allocation to intangible assets, other than in-place lease intangibles, is included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets and amortized over the term of the acquired intangible asset. The Company values land based on a market approach, looking to recent sales of similar properties, adjusting for differences due to location, the state of entitlement as well as the shape and size of the parcel. Improvements to land are valued using a replacement cost approach and consider the structures and amenities included for the communities and is reduced by estimated depreciation. The value for furniture, fixtures and equipment is also determined based on a replacement cost approach, considering costs for both items in the apartment homes as well as common areas and is adjusted for estimated depreciation. The fair value of buildings is estimated using the replacement cost approach, assuming the buildings were vacant at acquisition. The replacement cost approach considers the composition of structures acquired, adjusted for depreciation which considers industry standard information and estimated useful life of the acquired property. The value of the lease-related intangibles considers the estimated cost of leasing the apartment homes as if the acquired building(s) were vacant, as well as the value of the current leases relative to market-rate leases. The in-place lease value is determined using an average total lease-up time, the number of apartment homes and net revenues generated during the lease-up time. Net revenues use market rent considering actual leasing and industry rental rate data. The value of current leases relative to a market-rate lease is based on market comparables. Given the heterogeneous nature of multifamily real estate, the fair values for the land, debt, real estate assets and in-place leases incorporate significant unobservable inputs and therefore are considered to be Level 3 prices within the fair value hierarchy. Consideration for acquisitions is typically in the form of cash unless otherwise disclosed.

Depreciation is generally calculated on a straight-line basis over the estimated useful lives of the assets, which for buildings and related improvements range from seven to 30 years and for furniture, fixtures and equipment range from three years (primarily computer-related equipment) to seven years.
For-Sale Condominium Inventory

The Company presents for-sale condominium inventory at historical cost and evaluates the condominiums for impairment when potential indicators exist, as further discussed under "Abandoned Pursuit Costs and Impairment of Long-Lived Assets" below.

Income Taxes

The Company elected to be treated as a REIT for federal income tax purposes for its tax year ended December 31, 1994 and has not revoked such election. A REIT is a corporate entity which holds real estate interests and can deduct from its federally taxable income qualifying dividends it pays if it meets a number of organizational and operational requirements, including a requirement that it distribute at least 90% of its adjusted taxable income to stockholders. Therefore, as a REIT, the Company generally will not be subject to corporate level federal income tax on its taxable income if it annually distributes 100% of its taxable income to its stockholders.

The states in which the Company operates have similar tax provisions which recognize the Company as a REIT for state income tax purposes. Management believes that all such conditions for the exemption from income taxes on ordinary income have been or will be met for the periods presented. Accordingly, no provision for federal and state income taxes has been made. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal corporate income taxes at regular corporate rates and may not be able to qualify as a corporate REIT for four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income and in certain other instances.

The Company did not incur any charges or receive refunds of excise taxes related to the years ended December 31, 2020, 2019 and 2018.

Taxable income from activities performed through taxable REIT subsidiaries (“TRS”) is subject to federal, state and local income taxes. The Company recognized income tax benefit of $3,247,000 in 2020, recorded an income tax expense of $13,003,000 in 2019 and recognized income tax benefit of $160,000 in 2018, related to its activities through its TRSs. The income tax benefit in 2020 was primarily due to provisions of the Coronavirus Aid, Relief, and Economic Security Act, allowing for further carryback of net operating losses and operating losses for tax purposes. The income tax expense in 2019 was primarily due to (i) a net deferred tax liability of $5,782,000 for the GAAP to tax basis differences at the Company's for-sale condominiums, The Park Loggia, and the associated 66,000 square feet of commercial space and (ii) expense for current and net deferred tax liabilities of $7,221,000, associated with the disposition of two wholly-owned operating communities, as well as the Company's sustainability initiatives. As of December 31, 2020 and 2019, the Company did not have any unrecognized tax benefits. The Company does not believe that there will be any material changes in its unrecognized tax positions over the next 12 months. The Company is subject to examination by the respective taxing authorities for the tax years 2017 through 2019.

The following summarizes the tax components of the Company's common dividends declared for the years ended December 31, 2020, 2019 and 2018 (unaudited):

Deferred Financing Costs

Deferred financing costs include fees and other expenditures necessary to obtain debt financing and are amortized on a straight-line basis, which approximates the effective interest method, over the shorter of the term of the loan or the related credit enhancement facility, if applicable. Unamortized financing costs are charged to earnings when debt is retired before the maturity date. Accumulated amortization of deferred financing costs related to unsecured notes was $25,239,000 and $25,995,000 as of December 31, 2020 and 2019, respectively, and related to mortgage notes payable was $2,046,000 and $1,784,000 as of December 31, 2020 and 2019, respectively. Deferred financing costs, except for costs associated with line-of-credit arrangements, are presented as a direct deduction from the related debt liability. Accumulated amortization of deferred financing costs related to the Company's Credit Facility was $13,501,000 and $11,815,000 as of December 31, 2020 and 2019, respectively, and was included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets.
Cash, Cash Equivalents and Cash in Escrow

Cash and cash equivalents include all cash and liquid investments with an original maturity of three months or less from the date acquired. Cash in escrow includes principal reserve funds that are restricted for the repayment of specified secured financing. The majority of the Company's cash, cash equivalents and cash in escrow are held at major commercial banks.

Interest Rate Contracts

The Company utilizes derivative financial instruments to manage interest rate risk. See Note 11, “Fair Value,” for further discussion of derivative financial instruments.

Comprehensive Income

Comprehensive income, as reflected on the Consolidated Statements of Comprehensive Income, is defined as all changes in equity during each period except for those resulting from investments by or distributions to shareholders. Accumulated other comprehensive loss, as reflected on the Consolidated Statements of Equity, reflects the effective portion of the cumulative changes in the fair value of derivatives in qualifying cash flow hedge relationships.

Earnings per Common Share

Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted average number of shares outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per share (“EPS”). Both the unvested restricted shares and other potentially dilutive common shares, and the related impact to earnings, are considered when calculating earnings per share on a diluted basis. The Company's earnings per common share are determined as follows (dollars in thousands, except per share data):

Abandoned Pursuit Costs and Impairment of Long-Lived Assets

The Company capitalizes pre-development costs incurred in pursuit of new development opportunities for which the Company currently believes future development is probable (“Development Rights”). Future development of these Development Rights is dependent upon various factors, including zoning and regulatory approval, rental market conditions, construction costs and the availability of capital. Initial pre-development costs incurred for pursuits for which future development is not yet considered probable are expensed as incurred. In addition, if the status of a Development Right changes, making future development by the Company no longer probable, any non-recoverable capitalized pre-development costs are expensed. The Company expensed costs related to development pursuits not yet considered probable for development and the abandonment of Development Rights, as well as costs incurred in pursuing the acquisition or disposition of assets for which such acquisition and disposition activity did not occur, in the amounts of $12,317,000, $4,896,000 and $4,388,000 during the years ended December 31, 2020, 2019 and 2018, respectively. These costs are included in expensed transaction, development and other pursuit costs, net of recoveries on the accompanying Consolidated Statements of Comprehensive Income. The amount for 2020 includes the write-off of $7,264,000 related to a Development Right in New York City that the Company no longer expects is probable. Abandoned pursuit costs can vary greatly, and the costs incurred in any given period may be significantly different in future periods.

In the Company's evaluation of its real estate portfolio for impairment, as discussed below, it considered the impact of the COVID-19 pandemic and did not identify any indicators of impairment as a result.

The Company evaluates its real estate and other long-lived assets for impairment when potential indicators of impairment exist. Such assets are stated at cost, less accumulated depreciation and amortization, unless the carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of a property or long-lived asset may not be recoverable, the Company assesses its recoverability by comparing the carrying amount of the property or long-lived asset to its estimated undiscounted future cash flows. If the carrying amount exceeds the aggregate undiscounted future cash flows, the Company recognizes an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property or long-lived asset. Based on periodic tests of recoverability of long-lived assets, for the years ended December 31, 2020, 2019 and 2018, the Company did not recognize any impairment losses other than those related to the impairment on land held for investment and casualty gains and losses from property damage as discussed below.

The Company evaluates its for-sale condominium inventory for potential indicators of impairment, considering whether the fair value of the individual for-sale condominium units exceeds the carrying value of those units. For-sale condominium inventory is stated at cost, unless the carrying amount of the inventory is not recoverable when compared to the fair value of each unit. The Company determines the fair value of its for-sale condominium inventory using estimated undiscounted future cash flows. For the years ended December 31, 2020 and 2019, the Company did not recognize any impairment losses on its for-sale condominium inventory.

The Company assesses its portfolio of land held for both development and investment for impairment if the intent of the Company changes with respect to either the development of, or the expected holding period for, the land. The Company did not recognize any impairment charges on its investment in land during the years ended December 31, 2020 and 2019. During the year ended December 31, 2018, the Company recognized an impairment charge of $826,000 related to a land parcel the Company had previously acquired for development and subsequently sold. This charge was determined as the excess of the Company's carrying basis over the sales price, and is included in casualty and impairment loss (gain), net on the accompanying Consolidated Statements of Comprehensive Income.

The Company evaluates its unconsolidated investments for other than temporary impairment, considering both the extent and amount by which the carrying value of the investment exceeds the fair value, and the Company’s intent and ability to hold the investment to recover its carrying value. The Company also evaluates its proportionate share of any impairment of assets held by unconsolidated investments. There were no other than temporary impairment losses recognized by any of the Company's investments in unconsolidated real estate entities during the years ended December 31, 2020, 2019 or 2018.
Assets Held for Sale and Discontinued Operations

The Company presents the assets and liabilities of any communities which have been sold, or otherwise qualify as held for sale, separately in the Consolidated Balance Sheets. In addition, the results of operations for those assets that meet the definition of discontinued operations are presented as such in the accompanying Consolidated Statements of Comprehensive Income. Real estate assets held for sale are measured at the lower of the carrying amount or the fair value less the cost to sell. Both the real estate assets and corresponding liabilities are presented separately in the accompanying Consolidated Balance Sheets. Upon the classification of an asset as held for sale, no further depreciation is recorded. Disposals representing a strategic shift in operations (e.g., a disposal of a major geographic area, a major line of business or a major equity method investment) will be presented as discontinued operations, and for those assets qualifying for classification as discontinued operations, the specific components of net income presented as discontinued operations include net operating income, depreciation expense and interest expense, net. For periods prior to the asset qualifying for discontinued operations, the Company reclassifies the results of operations to discontinued operations. In addition, the net gain or loss (including any impairment loss) on the eventual disposal of assets held for sale will be presented as discontinued operations when recognized. A change in presentation for held for sale or discontinued operations has no impact on the Company's financial condition or results of operations. The Company combines the operating, investing and financing portions of cash flows attributable to discontinued operations with the respective cash flows from continuing operations on the accompanying Consolidated Statements of Cash Flows. The Company had one wholly-owned operating community that qualified as held for sale presentation at December 31, 2020.

Derivative Instruments and Hedging Activities

The Company enters into interest rate swap and interest rate cap agreements (collectively, "Hedging Derivatives") for interest rate risk management purposes and in conjunction with certain variable rate secured debt to satisfy lender requirements. The Company does not enter into Hedging Derivative transactions for trading or other speculative purposes. The Company assesses the effectiveness of qualifying cash flow and fair value hedges, both at inception and on an on-going basis. Hedge ineffectiveness is reported as a component of interest expense, net. The fair values of Hedging Derivatives that are in an asset position are recorded in prepaid expenses and other assets. The fair value of Hedging Derivatives that are in a liability position are included in accrued expenses and other liabilities. The Company does not present or disclose the fair value of Hedging Derivatives on a net basis. Fair value changes for derivatives that are not in qualifying hedge relationships are reported as a component of interest expense, net.  For the Hedging Derivative positions that the Company has determined qualify as effective cash flow hedges, the Company has recorded the cumulative changes in the fair value of Hedging Derivatives in other comprehensive loss.  Amounts recorded in accumulated other comprehensive loss will be reclassified into earnings in the periods in which earnings are affected by the hedged cash flow. The effective portion of the change in fair value of the Hedging Derivatives that the Company has determined qualified as effective fair value hedges is reported as an adjustment to the carrying amount of the corresponding debt being hedged. See Note 11, “Fair Value,” for further discussion of derivative financial instruments.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Reclassifications

Certain reclassifications have been made to amounts in prior years' notes to financial statements to conform to current year presentations as a result of changes in held for sale classification, disposition activity and segment classification.

Leases

The Company is party to leases as both a lessor and a lessee, primarily as follows:

lessor of residential and commercial space within its apartment communities; and
lessee under (i) ground leases for land underlying current operating or development communities and certain commercial and parking facilities and (ii) office leases for its corporate headquarters and regional offices.
Lessee Considerations

The Company assesses whether a contract is or contains a lease based on whether the contract conveys the right to control the use of an identified asset, including specified portions of larger assets, for a period of time in exchange for consideration. The Company’s leases include both fixed and variable lease payments, which are based on an index or rate such as the consumer price index (CPI) or percentage rents based on total sales. Lease payments included in the lease liability include only payments that depend on an index or rate. For leases that have options to extend the term or terminate the lease early, the Company only factored the impact of such options into the lease term if the option was considered reasonably certain to be exercised. The Company determined the discount rate associated with its ground and office leases on a lease by lease basis using the Company’s actual borrowing rates as well as indicative market pricing for longer term rates and taking into consideration the remaining term of each of the lease agreements.

Lessor Considerations

The Company evaluates leases in which it is the lessor, which are composed of residential and commercial leases at its apartment communities, and determined these leases to be operating leases. For lease agreements that provide for rent concessions and/or scheduled fixed and determinable rent increases, rental income is recognized on a straight-line basis over the noncancellable term of the lease, which, for residential leases, is generally one year. Some of the Company’s commercial leases have fixed-price renewal options, and the lessee may be able to exercise its renewal option at an amount less than the fair value of the rent at such time. The Company only includes renewal options in the lease term if, at the commencement of the lease, it is reasonably certain that the lessee will exercise this option.

Additionally, for the Company’s residential and commercial leases, which are comprised of the lease component and common area maintenance as a non-lease component, the Company determined that (i) the leases are operating leases, (ii) the lease component is the predominant component and (iii) that all components of its operating leases share the same timing and pattern of transfer.

The Company changed its presentation of charges for uncollectible lease revenue associated with its residential and commercial leasing activity, reflecting those amounts as a component of rental and other income on the accompanying Consolidated Statement of Comprehensive Income beginning with the year ended December 31, 2019. However, in accordance with its prospective adoption of the lease standard, the Company did not adjust the presentation of charges for uncollectible lease revenue associated with its residential and commercial leasing activity as a component of operating expenses, excluding property taxes, on the accompanying Consolidated Statement of Comprehensive Income for the year ended December 31, 2018.

Revenue and Gain Recognition

Under ASU 2014-09, Revenue from Contracts with Customers, the Company recognizes revenue in accordance with the transfer of goods and services to customers at an amount that reflects the consideration that the Company expects to be entitled to for those goods and services. The majority of the Company’s revenue is derived from residential and commercial rental income and other lease income, which are accounted for under ASC 842, Leases, discussed above. The Company's revenue streams that are not accounted for under ASC 842 include:

Management fees - The Company has investment interests in real estate joint ventures, for which the Company may manage (i) the venture, (ii) the associated operating communities owned by the ventures and/or (iii) the development or redevelopment of those operating communities. For these activities, the Company receives asset management, property management, development and/or redevelopment fee revenue. The performance obligation is the management of the venture, community or other defined task such as the development or redevelopment of the community. While the individual activities that comprise the performance obligation of the management fees can vary day to day, the nature of the overall performance obligation to provide management service is the same and considered by the Company to be a series of services that have the same pattern of transfer to the customer and the same method to measure progress toward satisfaction of the performance obligation. The Company recognizes revenue for fees as earned on a monthly basis.

Rental and non-rental related income - The Company recognizes revenue for new rental related income not included as components of a lease, such as reservation and application fees, as well as for non-rental related income, as earned.
Gains or losses on sales of real estate - The Company accounts for the sale of real estate assets and any related gain recognition in accordance with the accounting guidance applicable to sales of real estate, which establishes standards for recognition of profit on all real estate sales transactions, other than commercial land sales. The Company recognizes the sale, and associated gain or loss from the disposition when the criteria for the sale of an asset have been met, which include when (i) a contract exists and (ii) the buyer obtained control of the nonfinancial asset that was sold. In addition, a gain or loss recognized on the sale of a nonfinancial asset to an unconsolidated entity is recognized at 100%, and not the Company’s proportionate ownership percentage.

The following table provides details of the Company’s revenue streams disaggregated by the Company’s reportable operating segments, further discussed in Note 8, “Segment Reporting,” for the years ended December 31, 2020, 2019 and 2018. The segments are classified based on the individual community's status at January 1, 2020 for the years ended December 31, 2020 and 2019, and at January 1, 2019 for the year ended December 31, 2018. Segment information for total revenue has been adjusted to exclude the real estate assets that were sold from January 1, 2018 through December 31, 2020, or otherwise qualify as held for sale as of December 31, 2020, as described in Note 6, "Real Estate Disposition Activities." Additionally, as discussed above, the Company changed its presentation of charges for uncollectible lease revenue beginning with the year ended December 31, 2019, including it as an adjustment to revenue and not as a component of operating expenses. In order to provide comparability between periods presented in the Company's segment reporting, the Company has included charges for uncollectible lease revenue for its segment results as a component of revenue for the year ended December 31, 2018. Total revenue for the year ended December 31, 2018 as presented in the following table includes $14,072,000 of charges for uncollectible lease revenue. See Note 8, "Segment Reporting," for further discussion (dollars in thousands):

Lease Revenue Reserves

The Company assesses the collectability of its lease revenue and receivables on an on-going basis. Under ASC 842, Lease Accounting, the Company assesses the probability of receiving all remaining lease amounts due on a lease by lease basis, reserving for revenue and the related receivables for those leases where collection of substantially all of the remaining lease payments is not probable. Subsequently, the Company will only recognize revenue to the extent cash is received. If the Company determines that collection of the remaining lease payments becomes probable at a future date, the Company will recognize the cumulative revenue that would have been recorded under the original lease agreement.

In addition to the specific reserves recognized under ASC 842, the Company also evaluates its lease receivables for collectability at a portfolio level under ASC 450, Contingencies – Loss Contingencies. The Company recognizes a reserve under ASC 450 when the uncollectible revenue is probable and reasonably estimable. The Company applies this reserve to the population of the Company’s revenue and receivables not specifically addressed as part of the specific ASC 842 reserve.

COVID-19 Pandemic

In March 2020, the World Health Organization designated COVID-19 as a pandemic. While the Company has taken various actions in response to the COVID-19 pandemic, the ultimate impact on its consolidated results of operations, cash flows, financial condition and liquidity will depend on (i) the duration and severity of the pandemic, (ii) the effectiveness of vaccines and the timing of vaccine availability, (iii) the duration and nature of governmental responses to contain the spread of the disease and assist consumers and businesses, (iv) consumer and business responses to the pandemic, including preferences for where and how to live and work, and (iv) how quickly and to what extent normal economic and operating conditions can resume. Because of this uncertainty, any estimate of the expected impact of the COVID-19 pandemic on results of operations, cash flows, financial condition, or liquidity for periods beyond the year ended December 31, 2020 is uncertain.

As of December 31, 2020, the Company assessed the collectibility of the outstanding lease income receivables as a result of the impact of the COVID-19 pandemic on its residential and commercial lease portfolios. The Company recorded an aggregate offset to income for uncollectible lease revenue for its residential and commercial portfolios of $66,763,000 for the year ended December 31, 2020 under ASC 842 and ASC 450, Contingencies.

Recently Issued and Adopted Accounting Standards

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. This ASU requires entities to estimate a lifetime expected credit loss for most financial assets, including (i) trade and other receivables, (ii) other long term financings including available for sale and held-to-maturity debt securities and (iii) loans. Subsequently, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which amends the scope of ASU 2016-13 and clarified that receivables arising from operating leases are not within the scope of the standard and should continue to be accounted for in accordance with the leases standard (Topic 842). The new standard was adopted on January 1, 2020 and does not have a material effect on the Company’s financial position or results of operations.
