Explanatory Note

This report combines the Quarterly Reports on Form 10-Q for the quarter ended June 30, 2020 of Mid-America Apartment Communities, Inc., a Tennessee corporation, and Mid-America Apartments, L.P., a Tennessee limited partnership, of which Mid-America Apartment Communities, Inc. is the sole general partner.  Mid-America Apartment Communities, Inc. and its 96.6% owned subsidiary, Mid-America Apartments, L.P., are both required to file quarterly reports under the Securities Exchange Act of 1934, as amended.

Unless the context otherwise requires, all references in this Quarterly Report on Form 10-Q to “MAA” refer only to Mid-America Apartment Communities, Inc., and not any of its consolidated subsidiaries. Unless the context otherwise requires, all references in this report to “we,” “us,” “our,” or the “Company” refer collectively to Mid-America Apartment Communities, Inc., together with its consolidated subsidiaries, including Mid-America Apartments, L.P.  Unless the context otherwise requires, all references in this report to the “Operating Partnership” or “MAALP” refer to Mid-America Apartments, L.P., together with its consolidated subsidiaries. “Common stock” refers to the common stock of MAA, “preferred stock” refers to the preferred stock of MAA, and “shareholders” refers to the holders of shares of MAA’s common stock or preferred stock, as applicable. The common units of limited partnership interest in the Operating Partnership are referred to as “OP Units” and the holders of the OP Units are referred to as “common unitholders”.

As of June 30, 2020, MAA owned 114,365,203 OP Units (96.6% of the total number of OP Units).  MAA conducts substantially all of its business and holds substantially all of its assets, directly or indirectly, through the Operating Partnership, and by virtue of its ownership of the OP Units and being the Operating Partnership’s sole general partner, MAA has the ability to control all of the day-to-day operations of the Operating Partnership.

We believe combining the periodic reports of MAA and the Operating Partnership, including the notes to the condensed consolidated financial statements, into this report results in the following benefits:

• enhances investors’ understanding of MAA and the Operating Partnership by enabling investors to view the business as a whole in the same manner that management views and operates the business;

• eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the disclosure in this report applies to both MAA and the Operating Partnership; and

• creates time and cost efficiencies through the preparation of one combined report instead of two separate reports.

MAA, an S&P 500 company, is a multifamily-focused, self-administered and self-managed real estate investment trust, or REIT.  Management operates MAA and the Operating Partnership as one business. We believe it is important to understand the few differences between MAA and the Operating Partnership in the context of how MAA and the Operating Partnership operate as a consolidated company. MAA and the Operating Partnership are structured as an umbrella partnership REIT, or UPREIT. MAA’s interest in the Operating Partnership entitles MAA to share in cash distributions from, and in the profits and losses of, the Operating Partnership in proportion to MAA’s percentage interest therein and entitles MAA to vote on substantially all matters requiring a vote of the partners. MAA’s only material asset is its ownership of limited partnership interests in the Operating Partnership (other than cash held by MAA from time to time); therefore, MAA’s primary function is acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing certain debt of the Operating Partnership. The Operating Partnership holds, directly or indirectly, all of the real estate assets. Except for net proceeds from public equity issuances by MAA, which are contributed to the Operating Partnership in exchange for limited partnership interests, the Operating Partnership generates the capital required by the Company’s business through the Operating Partnership’s operations, direct or indirect incurrence of indebtedness and issuance of OP Units.

The presentation of MAA’s shareholders’ equity and the Operating Partnership’s capital are the principal areas of difference between the consolidated financial statements of MAA and those of the Operating Partnership.  MAA’s shareholders’ equity may include shares of preferred stock, shares of common stock, additional paid-in capital, cumulative earnings, cumulative distributions, noncontrolling interest, treasury shares, accumulated other comprehensive income and redeemable common stock.  The Operating Partnership’s capital may include common capital and preferred capital of the general partner (MAA), limited partners’ common capital and preferred capital, noncontrolling interest, accumulated other comprehensive income and redeemable common units.  Holders of OP Units (other than MAA) may require the Operating Partnership to redeem their OP Units from time to time, in which case the Operating Partnership may, at its option, pay the redemption price either in cash (in an amount per OP Unit equal, in general, to the average closing price of MAA’s common stock on the New York Stock Exchange, or NYSE, over a specified period prior to the redemption date) or by delivering one share of MAA’s common stock (subject to adjustment under specified circumstances) for each OP Unit so redeemed.

2

In order to highlight the material differences between MAA and the Operating Partnership, this Quarterly Report on Form 10-Q includes sections that separately present and discuss areas that are materially different between MAA and the Operating Partnership, including:

• the condensed consolidated financial statements in Item 1 of this report;

• certain accompanying notes to the condensed consolidated financial statements, including Note 2 - Earnings per Common Share of MAA and Note 3 - Earnings per OP Unit of MAALP; Note 4 - MAA Equity and Note 5 - MAALP Capital; and Note 8 - Shareholders’ Equity of MAA and Note 9 - Partners’ Capital of MAALP;

• the controls and procedures in Item 4 of this report; and

• the certifications included as Exhibits 31 and 32 to this report.

In the sections that combine disclosures for MAA and the Operating Partnership, this report refers to actions or holdings as being actions or holdings of the Company.  Although the Operating Partnership (directly or indirectly through one of its subsidiaries) is generally the entity that enters into contracts, holds assets and issues debt, management believes this presentation is appropriate for the reasons set forth above and because we operate the business through the Operating Partnership.  MAA, the Operating Partnership and its subsidiaries operate as one consolidated business, but MAA, the Operating Partnership and each of its subsidiaries are separate, distinct legal entities.

Mid-America Apartment Communities, Inc. and Mid-America Apartments, L.P.

Notes to Condensed Consolidated Financial Statements

(Unaudited)

1.Basis of Presentation and Principles of Consolidation and Significant Accounting Policies

Unless the context otherwise requires, all references to the “Company” refer collectively to Mid-America Apartment Communities, Inc., together with its consolidated subsidiaries, including Mid-America Apartments, L.P.  Unless the context otherwise requires, all references to “MAA” refer only to Mid-America Apartment Communities, Inc., and not any of its consolidated subsidiaries.  Unless the context otherwise requires, the references to the “Operating Partnership” or “MAALP” refer to Mid-America Apartments, L.P., together with its consolidated subsidiaries.  “Common stock” refers to the common stock of MAA and, unless the context otherwise requires, “shareholders” refers to the holders of shares of MAA’s common stock.  The common units of limited partnership interests in the Operating Partnership are referred to as “OP Units,” and the holders of the OP Units are referred to as “common unitholders”.

As of June 30, 2020, MAA owned 114,365,203 OP Units (or 96.6% of the total number of OP Units).  MAA conducts substantially all of its business and holds substantially all of its assets, directly or indirectly, through the Operating Partnership, and by virtue of its ownership of the OP Units and being the Operating Partnership’s sole general partner, MAA has the ability to control all of the day-to-day operations of the Operating Partnership.

Management believes combining the notes to the condensed consolidated financial statements of MAA and the Operating Partnership results in the following benefits:

• enhances a readers’ understanding of MAA and the Operating Partnership by enabling the reader to view the business as a whole in the same manner that management views and operates the business;

• eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the disclosure applies to both MAA and the Operating Partnership; and

• creates time and cost efficiencies through the preparation of one combined set of notes instead of two separate sets.

MAA, an S&P 500 company, is a multifamily-focused, self-administered and self-managed real estate investment trust, or REIT.  Management operates MAA and the Operating Partnership as one business. The management of the Company is comprised of individuals who are officers of MAA and employees of the Operating Partnership.  Management believes it is important to understand the few differences between MAA and the Operating Partnership in the context of how MAA and the Operating Partnership operate as a consolidated company.  MAA and the Operating Partnership are structured as an umbrella partnership REIT, or UPREIT. MAA’s interest in the Operating Partnership entitles MAA to share in cash distributions from, and in the profits and losses of, the Operating Partnership in proportion to MAA’s percentage interest therein and entitles MAA to vote on substantially all matters requiring a vote of the partners.  MAA’s only material asset is its ownership of limited partnership interests in the Operating Partnership (other than cash held by MAA from time to time); therefore, MAA’s primary function is acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing certain debt of the Operating Partnership. The Operating Partnership holds, directly or indirectly, all of the Company’s real estate assets.  Except for net proceeds from public equity issuances by MAA, which are contributed to the Operating Partnership in exchange for limited partnership interests, the Operating Partnership generates the capital required by the business through the Operating Partnership’s operations, direct or indirect incurrence of indebtedness and issuance of OP Units.

The presentations of MAA’s shareholders’ equity and the Operating Partnership’s capital are the principal areas of difference between the condensed consolidated financial statements of MAA and those of the Operating Partnership.  MAA’s shareholders’ equity may include shares of preferred stock, shares of common stock, additional paid-in capital, cumulative earnings, cumulative distributions, noncontrolling interest, treasury shares, accumulated other comprehensive income and redeemable common stock.  The Operating Partnership’s capital may include common capital and preferred capital of the general partner (MAA), limited partners’ common capital and preferred capital, noncontrolling interest, accumulated other comprehensive income and redeemable common units.  Holders of OP Units (other than MAA) may require the Operating Partnership to redeem their OP Units from time to time, in which case the Operating Partnership may, at its option, pay the redemption price either in cash (in an amount per OP Unit equal, in general, to the average closing price of MAA’s common stock on the New York Stock Exchange, or NYSE, over a specified period prior to the redemption date) or by delivering one share of MAA’s common stock (subject to adjustment under specified circumstances) for each OP Unit so redeemed.

Organization of Mid-America Apartment Communities, Inc.

The Company owns, operates, acquires and selectively develops apartment communities primarily located in the Southeast, Southwest and Mid-Atlantic regions of the United States.  As of June 30, 2020, the Company owned and operated 299 apartment communities through the Operating Partnership and its subsidiaries and had an ownership interest in one apartment community through an unconsolidated real estate joint venture.  As of June 30, 2020, the Company had six development communities under construction totaling 1,940 apartment units once complete.  Total expected costs for the six development projects are $459.5 million, of which $215.8 million had been incurred through June 30, 2020.  MAA expects to complete one of these developments in 2020, four

12

developments in 2021 and one development in 2022. As of June 30, 2020, thirty-two of the Company’s apartment communities included retail components with approximately 630,000 square feet of gross leasable space.  In addition, as of June 30, 2020, the Company had four commercial properties with approximately 260,000 square feet of combined gross leasable area.  The Company’s apartment communities and commercial properties were located across 16 states and the District of Columbia as of June 30, 2020.

Basis of Presentation and Principles of Consolidation

The accompanying condensed consolidated financial statements have been prepared by the Company’s management in accordance with United States generally accepted accounting principles, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or the SEC.  The condensed consolidated financial statements of MAA presented herein include the accounts of MAA, the Operating Partnership and all other subsidiaries in which MAA has a controlling financial interest. MAA owns, directly or indirectly, approximately 80% to 100% of all consolidated subsidiaries, including the Operating Partnership.  The condensed consolidated financial statements of MAALP presented herein include the accounts of MAALP and all other subsidiaries in which MAALP has a controlling financial interest.  MAALP owns, directly or indirectly, 80% to 100% of all consolidated subsidiaries.  In management’s opinion, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included, and all such adjustments were of a normal recurring nature.  All significant intercompany accounts and transactions have been eliminated in consolidation.

The Company invests in entities which may qualify as variable interest entities, or VIEs, and MAALP is considered a VIE.  A VIE is a legal entity in which the equity investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the holders of the equity investment at risk lack the power to direct the activities of a legal entity as well as the obligation to absorb its expected losses or the right to receive its expected residual returns.  MAALP is classified as a VIE, because the limited partners lack substantive kick-out rights and substantive participating rights.  The Company consolidates all VIEs for which it is the primary beneficiary and uses the equity method to account for investments that qualify as VIEs but for which it is not the primary beneficiary.  In determining whether the Company is the primary beneficiary of a VIE, management considers both qualitative and quantitative factors, including, but not limited to, those activities that most significantly impact the VIE’s economic performance and which party controls such activities.  The Company uses the equity method of accounting for its investments in entities for which the Company exercises significant influence, but does not have the ability to exercise control.  The factors considered in determining whether the Company has the ability to exercise control include ownership of voting interests and participatory rights of investors (see “Investments in Unconsolidated Affiliates” below).

Reclassifications

In order to present comparative financial statements, certain reclassifications have been made to the Condensed Consolidated Statements of Operations. Prior year amounts have been changed to conform to the Company’s current year presentation.  As a result of these reclassifications, $0.2 million and $1.0 million of expenses previously reported as “General and administrative expenses” for the three and six months ended June 30, 2019, respectively, have been reclassified to the “Other non-operating (income) expense” line item of the Condensed Consolidated Statements of Operations in this report.

Noncontrolling Interests

As of June 30, 2020, the Company had two types of noncontrolling interests with respect to its consolidated subsidiaries, (1) noncontrolling interests related to the common unitholders of its Operating Partnership and (2) noncontrolling interests related to its consolidated real estate entities.  The noncontrolling interests relating to the limited partnership interests in the Operating Partnership are owned by the holders of the Class A OP Units. MAA is the sole general partner of the Operating Partnership and holds all of the outstanding Class B OP Units. Net income (after allocations to preferred ownership interests) is allocated to MAA and the noncontrolling interests based on their respective ownership percentages of the Operating Partnership. Issuance of additional Class A OP Units or Class B OP Units changes the ownership percentage of both the noncontrolling interests and MAA. The issuance of Class B OP Units generally occurs when MAA issues common stock and the issuance proceeds are contributed to the Operating Partnership in exchange for Class B OP Units equal to the number of shares of MAA’s common stock issued. At each reporting period, the allocation between total MAA shareholders’ equity and noncontrolling interests is adjusted to account for the change in the respective percentage ownership of the underlying equity of the Operating Partnership. MAA’s Board of Directors established economic rights in respect to each Class A OP Unit that were equivalent to the economic rights in respect to each share of MAA common stock. See Note 9 for additional details.

The noncontrolling interests relating to the Company’s two consolidated real estate entities are owned by private real estate companies that are generally responsible for the development and construction of the apartment communities that are owned through the consolidated real estate entities with a noncontrolling interest.  The entities were determined to be VIE’s with the Company designated as the primary beneficiary.  As a result, the accounts of the entities are consolidated by the Company.  As of June 30, 2020, the consolidated assets and liabilities of the Company’s consolidated real estate entities with a noncontrolling interest were $77.2 million and $8.4 million, respectively.  As of December 31, 2019, the consolidated assets and liabilities of the Company’s consolidated real estate entities with a noncontrolling interest were $46.0 million and $3.2 million, respectively.

Investments in Unconsolidated Affiliates

The Company uses the equity method to account for its investments in a real estate joint venture and two technology-focused limited partnerships that qualify as a VIE. Management determined the Company is not the primary beneficiary in any of these investments but does have the ability to exert significant influence over the operations and financial policies of the real estate joint venture and considers its investment in the limited partnerships to be more than minor. The Company’s investment in the real estate joint venture was $43.6 million and $43.7 million as of June 30, 2020 and December 31, 2019, respectively.

As of June 30, 2020 and December 31, 2019, the Company’s investments in the technology-focused limited partnerships were $19.7 million and $13.1 million, respectively, and are included in “Other assets” in the accompanying Condensed Consolidated Balance Sheets. As of June 30, 2020, the Company was committed until February 2025 to make additional capital contributions totaling $23.0 million if and when called by the general partners of the limited partnerships.

Fair Value Measurements

The Company applies the guidance in Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, to the valuation of real estate assets recorded at fair value, to its impairment valuation analysis of real estate assets, to its disclosure of the fair value of financial instruments, principally indebtedness and to its derivative financial instruments.  Fair value disclosures required under ASC Topic 820 as well as the Company’s derivative accounting policies are summarized in Note 7 utilizing the following hierarchy:

Level 1 - Quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date.

Level 2 - Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly.

Level 3 - Unobservable inputs for the assets or liability.

Revenue Recognition

The Company primarily leases multifamily residential apartments to residents under operating leases generally due on a monthly basis with terms of approximately one year or less.  Rental revenues are recognized in accordance with ASC Topic 842, Leases, using a method that represents a straight-line basis over the term of the lease. In addition, in circumstances where a lease incentive is provided to tenants, the incentive is recognized as a reduction of rental revenues on a straight-line basis over the reasonably assured lease term.  Rental revenues represent approximately 93% of the Company’s total revenues and include gross rents charged less adjustments for concessions and bad debt.  Approximately 6% of the Company’s total revenues represent non-lease reimbursable property revenues from its residents for utility reimbursements, which are generally recognized and due on a monthly basis as residents obtain control of the service over the term of the lease.  The remaining 1% of the Company’s total revenues represents other non-lease property revenues primarily driven by nonrefundable fees and commissions.

In accordance with ASC Topic 842, rental revenues and non-lease reimbursable property revenues meet the criteria to be aggregated into a single lease component and are reported on a combined basis in the line item “Rental revenues”, as presented in the disaggregation of the Company’s revenues in Note 11.  Other non-lease property revenues are accounted for in accordance with ASC Topic 606, Revenue from Contracts with Customers, which requires revenue recognized outside of the scope of ASC Topic 842 to be recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. Other non-lease property revenues are reported in the line item “Other property revenues”, as presented in the disaggregation of the Company’s revenues in Note 11.

Leases

The Company is the lessee under certain ground, office, equipment and other operational leases, all of which are accounted for as operating leases in accordance with ASC Topic 842. The Company recognizes a right-of-use asset for the right to use the underlying asset for all leases where the Company is the lessee with terms of more than twelve months, and a related lease liability for the obligation to make lease payments. Expenses related to leases determined to be operating leases are recognized on a straight-line basis.  As of June 30, 2020 and December 31, 2019, right-of-use assets recorded within “Other assets” totaled $50.6 million and $53.8 million, respectively, and related lease obligations recorded within “Accrued expenses and other liabilities” totaled $32.5 million and $33.1 million, respectively, in the Condensed Consolidated Balance Sheets.  As of June 30, 2020, the Company’s operating leases had a weighted average remaining lease term of approximately 31 years and a weighted average discount rate of approximately 4.4%. Lease expense recognized for the three and six months ended June 30, 2020 and 2019 was immaterial to the Company. Cash paid for amounts included in the measurement of operating lease liabilities during the six months ended June 30, 2020 and 2019 was also immaterial.

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Measurement of Credit Losses on Financial Instruments, which amends the current approach to estimate credit losses on certain financial assets, including trade and other receivables, available-for-sale securities and other financial instruments.  The ASU requires entities to estimate a lifetime expected credit loss for most financial instruments, including trade receivables.  Subsequent changes in the valuation allowance are recorded in current earnings and reversal of previous losses is permitted.  In November 2018, the FASB issued an amendment excluding operating lease receivables accounted for under ASC Topic 842 from the scope of the new credit losses standard. The Company adopted the standard on January 1, 2020. The adoption of ASU No. 2016-13 did not result in significant changes in the accounting for the Company’s approach to estimate credit losses on financial assets, as substantially all of the Company’s financial assets are operating lease receivables.   

2.Earnings per Common Share of MAA

Basic earnings per share is computed by dividing net income available to MAA common shareholders by the weighted average number of common shares outstanding during the period.  All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per share.  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 with diluted earnings per share being the more dilutive of the treasury stock or two-class methods.  OP Units are included in dilutive earnings per share calculations when the units are dilutive to earnings per share.

For the three and six months ended June 30, 2020 and 2019, MAA’s diluted earnings per share was computed using the treasury stock method as presented below (dollars and shares in thousands, except per share amounts):

	Three months ended June 30,						Six months ended June 30,
	2020			2019			2020			2019

⁽¹⁾ For the three and six months ended June 30, 2020 and 2019, 4.1 million OP Units and their related income are not included in the diluted earnings per share calculations as they are not dilutive.

3.Earnings per OP Unit of MAALP

Basic earnings per common unit is computed by dividing net income available for common unitholders by the weighted average number of OP Units outstanding during the period.  All outstanding unvested restricted unit awards contain rights to non-forfeitable distributions and participate in undistributed earnings with common unitholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per common unit.  Diluted earnings per common unit reflects the potential dilution that could occur if securities or other contracts to issue OP Units were exercised or converted into OP Units.  Both the unvested restricted unit awards and other potentially dilutive common units, and the related impact to earnings, are considered when calculating earnings per common unit on a diluted basis with diluted earnings per common unit being the more dilutive of the treasury stock or two-class methods.

For the three and six months ended June 30, 2020 and 2019, MAALP’s diluted earnings per common unit was computed using the treasury stock method as presented below (dollars and units in thousands, except per unit amounts):

	Three months ended June 30,						Six months ended June 30,

Unsecured Revolving Credit Facility

In May 2019, MAALP entered into a $1.0 billion unsecured revolving credit facility with a syndicate of banks led by Wells Fargo Bank, National Association, or Wells Fargo, and fourteen other banks, which is referred to as the Credit Facility.  The Credit Facility replaced MAALP’s previous unsecured revolving credit facility, and it includes an expansion option up to $1.5 billion.  The Credit Facility bears an interest rate of the London Interbank Offered Rate, or LIBOR, plus a spread of 0.75% to 1.45% based on an investment grade pricing grid. The Credit Facility matures in May 2023 with an option to extend for two additional six-month periods.  As of June 30, 2020, there was no outstanding balance under the Credit Facility, while $3.1 million of capacity was used to support outstanding letters of credit.

Unsecured Commercial Paper

In May 2019, MAALP established an unsecured commercial paper program whereby MAALP may issue unsecured commercial paper notes with varying maturities not to exceed 397 days up to a maximum aggregate principal amount outstanding of $500.0 million.  As of June 30, 2020, MAALP had $90.0 million outstanding under the commercial paper program. For the three months ended June 30, 2020, the average daily borrowings outstanding under the commercial paper program were $65.0 million.  

Unsecured Senior Notes

As of June 30, 2020, MAALP had $3.3 billion of publicly issued unsecured senior notes outstanding and $222.0 million of privately placed unsecured senior notes outstanding.  The unsecured senior notes had maturities at issuance ranging from ten to twelve years, with a weighted average of 6.1 years remaining until maturity as of June 30, 2020.

Unsecured Term Loan

As of June 30, 2020, MAALP maintained one term loan with a syndicate of banks led by Wells Fargo. The term loan has a balance of $300.0 million and matures in March 2022.  The term loan has a variable interest rate of LIBOR plus a spread of 0.90% to 1.75% based on the Company’s credit ratings.      

Secured Property Mortgages

As of June 30, 2020, MAALP had $626.3 million of fixed rate conventional property mortgages with a weighted average interest rate of 4.50% and a weighted average maturity in 2037.

Guarantees

As of June 30, 2020, MAA fully and unconditionally guaranteed $222.0 million of the privately placed unsecured senior notes issued by MAALP.

7.Financial Instruments and Derivatives

Financial Instruments Not Carried at Fair Value

Cash and cash equivalents, restricted cash and accrued expenses and other liabilities are carried at amounts that reasonably approximate their fair value due to their short term nature.

Fixed rate notes payable as of June 30, 2020 and December 31, 2019, totaled $4.1 billion and had estimated fair values of $4.6 billion and $4.5 billion (excluding prepayment penalties) as of June 30, 2020 and December 31, 2019, respectively. The carrying values of variable rate debt (excluding the effect of interest rate swap agreements) as of June 30, 2020 and December 31, 2019, totaled $0.4 billion and had estimated fair values of $0.4 billion (excluding prepayment penalties) as of June 30, 2020 and December 31, 2019. The fair values of fixed rate debt are determined by using the present value of future cash outflows discounted with the applicable current market rate plus a credit spread. The fair values of variable rate debt are determined using the stated variable rate plus the current market credit spread. The variable rates reset every 30 to 90 days, and management concluded these rates reasonably estimate current market rates.

Financial Instruments Measured at Fair Value on a Recurring Basis

As of June 30, 2020, the Company had one outstanding series of cumulative redeemable preferred stock, which is referred to as the MAA Series I preferred stock (see Note 8).  The Company has recognized a derivative asset related to the redemption feature embedded in the MAA Series I preferred stock. The derivative asset is valued using widely accepted valuation techniques, including a discounted cash flow analysis in which the perpetual value of the preferred shares is compared to the value of the preferred shares assuming the call option is exercised, with the value of the bifurcated call option as the difference between the two values. The analysis reflects the contractual terms of the redeemable preferred shares, which are redeemable at the Company’s option beginning on October 1, 2026 and at the redemption price of $50.00 per share. The Company uses various inputs in the analysis, including trading data available on the preferred shares, coupon yields on preferred stock issuances from REITs with similar credit ratings as MAA and treasury rates to determine the fair value of the bifurcated call option.

The redemption feature embedded in the MAA Series I preferred stock is reported as a derivative asset in “Other assets” in the accompanying Condensed Consolidated Balance Sheets and is adjusted to its fair value at each reporting date, with a corresponding non-cash adjustment to “Other non-operating (income) expense” in the accompanying Condensed Consolidated Statements of Operations.  As a result of adjustments of non-cash expense recorded to reflect the change in fair value of the derivative asset during the six months ended June 30, 2020, the fair value of the embedded derivative asset decreased to $20.5 million as of June 30, 2020 as compared to $36.5 million as of December 31, 2019.

Periodically, the Company uses interest rate swaps to add stability to interest expense and to manage, or hedge, its exposure to interest rate movements associated with anticipated future debt transactions and variable rate debt. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.

Management incorporates credit valuation adjustments to appropriately reflect both its nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of the derivative contracts for the effect of nonperformance risk, the Company considers the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Based on guidance issued by the FASB, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.

As of June 30, 2020, the Company did not have any outstanding interest rate derivatives designated as cash flow hedges of interest rate risk. The fair value of interest rate derivative contracts designated as hedging instruments recorded in “Other assets” in the accompanying Condensed Consolidated Balance Sheets as of December 31, 2019 was $0.1 million.  The Company’s interest rate derivative contracts designated as hedging instruments and their related gains and losses are reported in “Net change in operating accounts and other operating activities” in the accompanying Condensed Consolidated Statements of Cash Flows.

The Company has determined the majority of the inputs used to value its outstanding debt and its embedded derivative fall within Level 2 of the fair value hierarchy, and as a result, the fair value valuation of its debt and embedded derivative held as of June 30, 2020 and December 31, 2019 were classified as Level 2 in the fair value hierarchy.

Cash Flow Hedges of Interest Rate Risk

The changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in “Accumulated other comprehensive loss” and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. As long as a hedging instrument is designated and the results of the effectiveness testing support that the instrument qualifies

22

for hedge accounting treatment, there is no periodic measurement or recognition of ineffectiveness. Rather, the full impact of hedge gains and losses is recognized in the period in which hedged transactions impact earnings, regardless of whether or not economic mismatches exist in the hedging relationship.  Amounts reported in “Accumulated other comprehensive loss” related to derivatives designated as qualifying cash flow hedges are reclassified to interest expense as interest payments are made on the Company’s variable rate or fixed rate debt. During the next twelve months, the Company estimates that an additional $1.1 million will be reclassified to earnings as an increase to “Interest expense”, which primarily represents the difference between the fixed interest rate swap payments and the projected variable interest rate swap receipts.

See Note 7 for details of the valuation of the derivative asset related to the redemption feature embedded in the MAA Series I preferred stock.  

At-the-Market Share Offering Program

The Company has entered into separate distribution agreements with each of J.P. Morgan Securities LLC, BMO Capital Markets Corp. and KeyBanc Capital Markets Inc. to establish an at-the-market share offering program, or ATM program, allowing MAA to sell shares of its common stock from time to time into the existing market at current market prices or through negotiated transactions.  Under the ATM program, MAA has the authority to issue up to an aggregate of 4.0 million shares of its common stock, at such times

23

to be determined by MAA.  The ATM program currently has a maturity of September 28, 2021.  MAA has no obligation to issue shares through the ATM program.

During the six months ended June 30, 2020 and 2019, MAA did not sell any shares of common stock under its ATM program.  As of June 30, 2020, 3.9 million shares remained issuable under the ATM program.

9.Partners’ Capital of MAALP

Common units of limited partnership interests in MAALP are represented by OP Units.  As of June 30, 2020, there were 118,423,860 OP Units outstanding, 114,365,203, or 96.6%, of which represent Class B OP Units (common units issued to or held by MAALP’s general partner or any of its subsidiaries), which were owned by MAA, MAALP’s general partner.  The remaining 4,058,657 OP Units were Class A OP Units owned by Class A limited partners.  As of June 30, 2019, there were 118,133,172 OP Units outstanding, 114,043,089, or 96.5%, of which were owned by MAA and 4,090,083 of which were owned by the Class A limited partners.

MAA, as the sole general partner of MAALP, has full, complete and exclusive discretion to manage and control the business of MAALP subject to the restrictions specifically contained within MAALP’s agreement of limited partnership, or the Partnership Agreement.  Unless otherwise stated in the Partnership Agreement, this power includes, but is not limited to, acquiring, leasing or disposing of any real property; constructing buildings and making other improvements to properties owned; borrowing money, modifying or extinguishing current borrowings, issuing evidence of indebtedness and securing such indebtedness by mortgage, deed of trust, pledge or other lien on MAALP’s assets; and distribution of MAALP’s cash or other assets in accordance with the Partnership Agreement.  MAA can generally, at its sole discretion, issue and redeem OP Units and determine the consideration to be received or the redemption price to be paid, as applicable.  The general partner may delegate these and other powers granted if the general partner remains in supervision of the designee.

Under the Partnership Agreement, MAALP may issue Class A OP Units and Class B OP Units.  Class A OP Units are any OP Units other than Class B OP Units, while Class B OP Units are those issued to or held by MAALP’s general partner or any of its subsidiaries.  In general, the limited partners do not have the power to participate in the management or control of MAALP’s business except in limited circumstances, including changes in the general partner and protective rights if the general partner acts outside of the provisions provided in the Partnership Agreement.  The transferability of Class A OP Units is also limited by the Partnership Agreement.

Net income of MAALP (after allocations to preferred ownership interests) is allocated to the general partner and limited partners based on their respective ownership percentages of MAALP.  Issuance or redemption of additional Class A OP Units or Class B OP Units changes the relative ownership percentage of the partners.  The issuance of Class B OP Units generally occurs when MAA issues common stock and the proceeds from that issuance are contributed to MAALP in exchange for the issuance to MAA of a number of OP Units equal to the number of shares of common stock issued.  Likewise, if MAA repurchases or redeems outstanding shares of common stock, MAALP generally redeems an equal number of Class B OP Units with similar terms held by MAA for a redemption price equal to the purchase price of those shares of common stock.  At each reporting period, the allocation between general partner capital and limited partner capital is adjusted to account for the change in the respective percentage ownership of the underlying capital of MAALP.  Holders of the Class A OP Units may require MAA to redeem their Class A OP Units, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per Class A OP Unit equal, in general, to the average closing price of MAA’s common stock on the NYSE over a specified period prior to the redemption date) or by delivering one share of MAA common stock (subject to adjustment under specified circumstances) for each Class A OP Unit so redeemed.

As of June 30, 2020, a total of 4,058,657 Class A OP Units were outstanding and redeemable for 4,058,657 shares of MAA common stock, with an approximate value of $465.4 million, based on the closing price of MAA’s common stock on June 30, 2020 of $114.67 per share.  As of June 30, 2019, a total of 4,090,083 Class A OP Units were outstanding and redeemable for 4,090,083 shares of MAA common stock, with an approximate value of $481.6 million, based on the closing price of MAA’s common stock on June 28, 2019 of $117.76 per share.  MAALP pays the same per unit distributions in respect to the OP Units as the per share dividends MAA pays in respect to its common stock.

As of June 30, 2020, MAALP had one outstanding series of cumulative redeemable preferred units, or the MAALP Series I preferred units.  The MAALP Series I preferred units have the same characteristics as the MAA Series I preferred stock described in Note 8.  As of June 30, 2020, 867,846 units of the MAALP Series I preferred units were outstanding.

10.Commitments and Contingencies

Leases

The Company’s leases include a ground lease expiring in 2074 related to one of its apartment communities and an office lease expiring in 2028 related to its corporate headquarters.  Both leases contain stated rent increases that generally compensate for the impact of inflation.  The Company also has other commitments related to immaterial office and equipment operating leases.

The table below reconciles undiscounted cash flows for each of the first five years and total of the remaining years to the operating lease obligations recorded on the Condensed Consolidated Balance Sheets as of June 30, 2020 (in thousands):

Legal Proceedings

In June 2016, plaintiffs Cathi Cleven and Tara Cleven, on behalf of a purported class of plaintiffs, filed a complaint against MAA and the Operating Partnership in the United States District Court for the Western District of Texas, Austin Division.  In January 2017, Areli Arellano and Joe L. Martinez joined the lawsuit as additional plaintiffs.  The lawsuit alleges that the Company (but not Post Properties (see the description of the Brown class action lawsuit below)) charged late fees at its Texas properties that violate Section 92.019 of the Texas Property Code, or Section 92.019, which provides that a landlord may not charge a tenant a late fee for failing to pay rent unless, among other things, the fee is a reasonable estimate of uncertain damages to the landlord that are incapable of precise calculation and result from the late payment of rent.  The plaintiffs are seeking monetary damages and attorneys’ fees and costs.  In September 2018, the District Court certified a class proposed by the plaintiffs. Additionally, in September 2018, the District Court denied the Company’s motion for summary judgment and granted the plaintiffs’ motion for partial summary judgment.  Because the District Court certified a class prior to granting the plaintiffs’ motion for partial summary judgment, the District Court’s ruling applies to the entire class.  In October 2018, the Fifth Circuit Court of Appeals accepted the Company’s petition to review the District Court’s order granting class certification.  In September 2019, the Fifth Circuit Court of Appeals heard the Company’s oral arguments. The Company also intends to appeal the District Court’s order granting plaintiff’s motion for summary judgment to the Fifth Circuit Court of Appeals if permission to appeal is granted.  The Company will continue to vigorously defend the action and pursue such appeals.  Management estimates that the Company’s maximum exposure in the lawsuit, given the class certification and summary judgment ruling, is $54.6 million, which includes both potential damages and attorneys’ fees but excludes any prejudgment interest that may be awarded.

In April 2017, plaintiff Nathaniel Brown, on behalf of a purported class of plaintiffs, filed a complaint against the Operating Partnership, as the successor by merger to Post Properties’ primary operating partnership, and MAA in the United States District Court for the Western District of Texas, Austin Division.  The lawsuit alleges that Post Properties (and, following the Post Properties merger in December 2016, the Operating Partnership) charged late fees at its Texas properties that violate Section 92.019.  The plaintiffs are seeking monetary damages and attorney’s fees and costs.  In September 2018, the District Court certified a class proposed by the plaintiff.  Additionally, in September 2018, the District Court denied the Company’s motion for summary judgment and granted the plaintiff’s motion for partial summary judgment. Because the District Court certified a class prior to granting the plaintiff’s motion for partial summary judgment, the District Court’s ruling applies to the entire class.  In October 2018, the Fifth Circuit Court of Appeals accepted the Company’s petition to review the District Court’s order granting class certification. In September 2019, the Fifth Circuit Court of Appeals heard the Company’s oral arguments. The Company also intends to appeal the District Court’s order granting plaintiff’s motion for summary judgment to the Fifth Circuit Court of Appeals if permission to appeal is granted.  The Company will continue to vigorously defend the action and pursue such appeals.  Management estimates that the Company’s maximum exposure in the lawsuit, given the class certification and summary judgment ruling, is $8.4 million, which includes both potential damages and attorneys’ fees but excludes any prejudgment interest that may be awarded.

The Company is subject to various other legal proceedings and claims that arise in the ordinary course of its business operations.  Matters which arise out of allegations of bodily injury, property damage and employment practices are generally covered by insurance.  While the resolution of these other matters cannot be predicted with certainty, management does not currently believe that such matters, either individually or in the aggregate, will have a material adverse effect on the Company’s financial condition, results of operations or cash flows in the event of a negative outcome.

25

Loss Contingencies

The outcomes of claims, disputes and legal proceedings are subject to significant uncertainty.  The Company records an accrual for loss contingencies when a loss is probable and the amount of the loss can be reasonably estimated.  The Company also accrues an estimate of defense costs expected to be incurred in connection with legal matters.  Management reviews these accruals quarterly and makes revisions based on changes in facts and circumstances.  When a loss contingency is not both probable and reasonably estimable, management does not accrue the loss. However, if the loss (or an additional loss in excess of the accrual) is at least a reasonable possibility and material, then management discloses a reasonable estimate of the possible loss, or range of loss, if such reasonable estimate can be made.  If the Company cannot make a reasonable estimate of the possible loss, or range of loss, then a statement to that effect is disclosed.

The assessment of whether a loss is probable or a reasonable possibility, and whether the loss or range of loss is reasonably estimable, often involves a series of complex judgments about future events.  Among the factors considered in this assessment, are the nature of existing legal proceedings and claims, the asserted or possible damages or loss contingency (if reasonably estimable), the progress of the matter, existing law and precedent, the opinions or views of legal counsel and other advisers, management’s experience in similar matters, the facts available to management at the time of assessment, and how the Company intends to respond, or has responded, to the proceeding or claim.  Management’s assessment of these factors may change over time as individual proceedings or claims progress.  For matters where management is not currently able to reasonably estimate a range of reasonably possible loss, the factors that have contributed to this determination include the following: (i) the damages sought are indeterminate; (ii) the proceedings are in the early stages; (iii) the matters involve novel or unsettled legal theories or a large or uncertain number of actual or potential cases or parties; and/or (iv) discussions with the parties in matters that are ultimately expected to be resolved through negotiation and settlement have not reached the point where management believes a reasonable estimate of loss, or range of loss, can be made.  The Company believes that there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss or business impact, if any.

As of June 30, 2020 and December 31, 2019, the Company’s accrual for loss contingencies relating to unresolved legal matters was $8.5 million and $8.6 million in the aggregate, respectively.  The loss contingencies are presented in “Accrued expenses and other liabilities” in the accompanying Condensed Consolidated Balance Sheets.

11.Segment Information

As of June 30, 2020, the Company owned and operated 299 multifamily apartment communities in 16 different states from which it derived all significant sources of earnings and operating cash flows.  The Company views each consolidated apartment community as an operating segment. The Company’s chief operating decision maker, which is the Company’s Chief Executive Officer, evaluates performance and determines resource allocations of each of the apartment communities on a Same Store and Non-Same Store and Other basis, as well as an individual apartment community basis. This is consistent with the aggregation criteria under GAAP as each of the apartment communities generally has similar economic characteristics, facilities, services, and tenants.

The following reflects the two reportable segments for the Company:

• Same Store communities are communities that the Company has owned and have been stabilized for at least a full 12 months.

• Non-Same Store and Other includes recently acquired communities, communities in development or lease-up, communities that have been identified for disposition, communities that have incurred a significant casualty loss and stabilized communities that do not meet the requirements to be Same Store communities. Also included in Non-Same Store and Other are non-multifamily activities.

On the first day of each calendar year, the Company determines the composition of its Same Store and Non-Same Store and Other reportable segments for that year as well as adjusts the previous year, which allows the Company to evaluate full period-over-period operating comparisons.  Properties in development or lease-up are added to the Same Store portfolio on the first day of the calendar year after a community has been owned and stabilized for at least a full 12 months.  Communities are considered stabilized after achieving 90% occupancy for 90 days.  Communities that have been identified for disposition are excluded from the Same Store portfolio.

The chief operating decision maker utilizes net operating income, or NOI, in evaluating the performance of its operating segments.  Total NOI represents total property revenues less total property operating expenses, excluding depreciation and amortization, for all properties held during the period regardless of their status as held for sale.  Management believes that NOI is a helpful tool in evaluating the operating performance of the segments because it measures the core operations of property performance by excluding corporate level expenses and other items not directly related to property operating performance.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion analyzes the financial condition and results of operations of both MAA and the Operating Partnership, of which MAA is the sole general partner and in which MAA owned a 96.6% interest as of June 30, 2020. MAA conducts all of its business through the Operating Partnership and its various subsidiaries. This discussion should be read in conjunction with the condensed consolidated financial statements and notes thereto included elsewhere in this Quarterly Report on Form 10-Q.

MAA, an S&P 500 company, is a multifamily-focused, self-administered and self-managed real estate investment trust, or REIT. We own, operate, acquire and selectively develop apartment communities primarily located in the Southeast, Southwest and Mid-Atlantic regions of the United States.  As of June 30, 2020, we owned and operated 299 apartment communities through the Operating Partnership and its subsidiaries, and we had an ownership interest in one apartment community through an unconsolidated real estate joint venture and had six development communities under construction.  In addition, as of June 30, 2020, we owned four commercial properties, and 32 of our apartment communities included retail components.  Our apartment communities and commercial properties were located across 16 states and the District of Columbia as of June 30, 2020.

We report in two segments, Same Store and Non-Same Store and Other. Our Same Store segment represents those apartment communities that have been owned and stabilized for at least 12 months as of the first day of the calendar year. Our Non-Same Store and Other segment includes recently acquired communities, communities being developed or in lease-up, communities undergoing extensive renovations, communities identified for disposition and communities that have incurred a significant casualty loss. Also included in our Non-Same Store and Other segment are non-multifamily activities.  Additional information regarding the composition of our segments is included in Note 11 to the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Overview of the Three Months Ended June 30, 2020

For the three months ended June 30, 2020, net income available for MAA common shareholders was $74.1 million as compared to $61.0 million for the three months ended June 30, 2019.  Results for the three months ended June 30, 2020 included $11.7 million of non-cash income related to the fair value adjustment of the embedded derivative in the MAA Series I preferred shares and $4.3 million of non-cash income, net of tax, related to gains recognized from an unconsolidated limited partnership.  Results for the three months ended June 30, 2019 included $4.6 million of non-cash income related to the embedded derivative in the preferred shares. Revenues for the three months ended June 30, 2020 increased 1.4% as compared to the three months ended June 30, 2019, driven by a 2.1% increase in our Same Store segment, partially offset by a 9.7% decrease in our Non-Same Store and Other segment. Property operating expenses, excluding depreciation and amortization, for the three months ended June 30, 2020 increased by 2.2% as compared to the three months ended June 30, 2019, driven by a 2.4% increase in our Same Store segment. The drivers of these increases are discussed below in the “Results of Operations” section.

COVID-19 Developments

In these unprecedented times, we believe the best way we can help our residents is to work with those who have lost wages or compensation due to the COVID-19 pandemic so that they can remain in their homes. We have offered these impacted residents amendments to their leases that provided varying degrees of payment flexibility with respect to April, May, June and July rent and waived late fees and interest charges under the original lease for rent that was deferred under a lease amendment.

Our on-site leasing offices have remained open throughout the COVID-19 pandemic. As governmental authorities began issuing orders and directives to combat the spread of COVID-19, our leasing offices transitioned to operate on a virtual basis, with full staff still on-site to continue serving current and prospective new residents.  To support our associates who continued to work on-site on a daily basis, we provided those associates with enhanced leave and sick time policies, enhanced flextime arrangements and additional COVID-19 paid time off, among other benefits. In addition, we made modifications to our health and retirement plans to assist all of our associates and their families during this time of crisis.  In May, we resumed normal operations at our on-site leasing offices, once again permitting public access and walk-in traffic, subject to social distancing restrictions. Likewise, in May, we began reopening property amenities as permitted by governmental orders, directives and guidelines.

Our balance sheet remains very strong, with low leverage, significant availability from our unsecured revolving credit facility and limited near-term debt maturities and funding obligations.

Trends

During the three months ended June 30, 2020, revenue growth for our Same Store portfolio continued to be favorably impacted by in-place rents and the contribution to average effective rent per unit growth. The average effective rent per unit for our Same Store portfolio continued to increase from the prior year, up 3.4% for the three months ended June 30, 2020 as compared to the three months ended June 30, 2019. This growth was partially offset by lower occupancy and lower rent and fee collections as compared to the more normal operating conditions for the three months ended June 30, 2019. Average effective rent per unit represents the average of gross rent amounts, after the effect of leasing concessions, for occupied apartment units plus prevalent market rates asked for unoccupied apartment units, divided by the total number of units. Leasing concessions represent discounts to the current market rate. We believe average effective rent per unit is a helpful measurement in evaluating average pricing; however, it does not represent actual rental revenue collected per unit.

In addition, during the three months ended June 30, 2020, we maintained strong physical occupancy.  Average physical occupancy for our Same Store portfolio was 95.4% for the three months ended June 30, 2020, which compares to average physical occupancy of 96.0% achieved during the three months ended June 30, 2019.  Average physical occupancy is a measurement of the total number of our apartment units that are occupied by residents, and it represents the average of the daily physical occupancy for the period.

An important part of our portfolio strategy is to maintain diversity of markets, submarkets, product types and price points in the Southeast, Southwest and Mid-Atlantic regions of the United States. This diversity tends to mitigate exposure to economic issues in any one geographic market or area. We believe that a well-balanced portfolio, including inner loop, suburban and downtown/central business district locations, with various monthly rent price points, will perform well in “up” cycles as well as weather “down” cycles better. Through our investment in 36 defined markets, we are diversified across markets, urban and suburban submarkets, and a variety of product types and monthly rent pricing points.

The COVID-19 pandemic continues to disrupt the United States economy and we cannot predict when an economic recovery will occur. Demand for apartments is primarily driven by general economic conditions in our markets and is particularly correlated to job growth.  Government restrictions implemented in response to the pandemic continue to drive high unemployment and also limit the number of people looking to change their current living situation. We expect this environment could contribute to lower rent collections than normal in the third quarter of 2020 and also continue to suppress demand for apartments, likely driving rent growth on new leases and renewals lower than it would be in a more normal economic environment. Current elevated supply levels could further impact rent growth for our portfolio, particularly for apartment communities located in urban submarkets.  Properties in suburban submarkets have been impacted somewhat less by supply, primarily because less new development has occurred in those submarkets.

Our focus during this challenging time has been on working with residents who have been financially impacted by the pandemic on rent payment flexibility. At a portfolio level, we have focused on using our pricing system to maintain strong occupancy. As noted above, average physical occupancy for our Same Store portfolio for the three months ended June 30, 2020 was 95.4%, which we believe positions us well to manage through the current environment.  

Markets throughout the country have been impacted differently by the pandemic and the individual market economies continue to be at various stages of reopening and we expect them to stay this way for some period of time. Further, as COVID-19 cases continue to rise in most areas of the country including markets where we operate, we are unable to predict if economies will continue to remain open or if they will be disrupted again in the near future.  As we move through this uncertain time, we believe that our portfolio strategy of maintaining a diversity of markets, submarkets, product types, and price points will serve the company better in this environment than a more concentrated portfolio profile.

While access to the financial markets was initially disrupted by the COVID-19 pandemic, access has returned, particularly for high credit borrowers, and we believe we currently have the ability to raise capital through the debt and equity markets as necessary. However, a prolonged disruption of the markets or a decline in credit and financing conditions could negatively impact our ability to access capital necessary to fund our operations or refinance maturing debt.

Results of Operations

Comparison of the three months ended June 30, 2020 to the three months ended June 30, 2019

For the three months ended June 30, 2020, we achieved net income available for MAA common shareholders of $74.1 million, a 21.6% increase as compared to the three months ended June 30, 2019, and total revenue growth of $5.6 million, representing a 1.4% increase in property revenues as compared to the three months ended June 30, 2019.  The following discussion describes the primary drivers of the increase in net income available for MAA common shareholders for the three months ended June 30, 2020 as compared to the three months ended June 30, 2019.

Property Revenues

The following table reflects our property revenues by segment for the three months ended June 30, 2020 and 2019 (dollars in thousands):

	Three months ended June 30,
	2020		2019		Increase			% Increase
Same Store	$	389,894	$	381,762	$	8,132			2.1	%
Non-Same Store and Other		23,132		25,628		(2,496	)		(9.7	)%
Total	$	413,026	$	407,390	$	5,636			1.4	%

The increase in property revenues for our Same Store segment for the three months ended June 30, 2020 as compared to the three months ended June 30, 2019 was the primary driver of total property revenue growth.  The Same Store segment generated a 2.1% increase in revenues for the three months ended June 30, 2020, primarily a result of average effective rent per unit growth of 3.4% as compared to the three months ended June 30, 2019.  The decrease in property revenues from the Non-Same Store and Other segment for the three months ended June 30, 2020 as compared to three months ended June 30, 2019 was primarily the result of decreased revenues from our retail properties and from the disposition of our five multifamily properties located in the Little Rock, Arkansas market during the fourth quarter of 2019, which marked our exit from that particular market, These decreases were partially offset by increased revenues from recently completed development properties and 2019 multifamily acquisitions.  

Property Operating Expenses

Property operating expenses include costs for property personnel, building repairs and maintenance, real estate taxes and insurance, utilities, landscaping and other operating expenses. The following table reflects our property operating expenses by segment for the three months ended June 30, 2020 and 2019 (dollars in thousands):

	Three months ended June 30,
	2020		2019		Increase			% Increase
Same Store	$	147,181	$	143,746	$	3,435			2.4	%
Non-Same Store and Other		10,290		10,396		(106	)		(1.0	)%
Total	$	157,471	$	154,142	$	3,329			2.2	%

The increase in property operating expenses for our Same Store segment for the three months ended June 30, 2020 as compared to the three months ended June 30, 2019 was primarily driven by increases in real estate tax expense of $2.5 million, in addition to increases in marketing and insurance expenses.

Depreciation and Amortization

Depreciation and amortization expense for the three months ended June 30, 2020 was $127.2 million, an increase of $3.2 million as compared to the three months ended June 30, 2019. The increase was primarily driven by the recognition of depreciation expense associated with our development and redevelopment activities made after June 30, 2019 in the normal course of business through June 30, 2020.

Other Income and Expenses

Property management expenses for the three months ended June 30, 2020 were $11.7 million, a decrease of $1.7 million as compared to the three months ended June 30, 2019. General and administrative expenses for the three months ended June 30, 2020 were $10.6 million, an increase of $0.2 million as compared to the three months ended June 30, 2019.  

Interest expense for the three months ended June 30, 2020 was $42.1 million, a decrease of $3.8 million as compared to the three months ended June 30, 2019. The decrease was primarily due to decreased average daily debt outstanding as well as an increase in capitalized interest during the three months ended June 30, 2020 as compared to the three months ended June 30, 2019.  The increase in the capitalized interest expense was due to an increase in the number of development projects.  

31

During the three months ended June 30, 2019, we sold a land parcel resulting in a $0.3 million gain on sale of non-depreciable assets.  No land parcels were sold during the three months ended June 30, 2020.

Other non-operating (income) expense for the three months ended June 30, 2020 was $14.6 million of income, an increase of $10.1 million as compared to the three months ended June 30, 2019. The increase was primarily driven by $11.7 million of non-cash income related to the fair value adjustment of the embedded derivative in the MAA Series I preferred shares during the three months ended June 30, 2020, compared to the recognition of $4.6 million of non-cash income related to the adjustment of the embedded derivative during the three months ended June 30, 2019. During the three months ended June 30, 2020, we also recognized $5.0 million of non-cash income from an unconsolidated limited partnership and $2.4 million of COVID-19 related expenses in other non-operating (income) expense. Our COVID-19 related expenses consisted primarily of additional cleaning supplies, contract labor and COVID-19 related leave.

Comparison of the six months ended June 30, 2020 to the six months ended June 30, 2019

For the six months ended June 30, 2020, we achieved net income available for MAA common shareholders of $109.9 million, a 11.2% decrease as compared to the six months ended June 30, 2019, and total revenue growth of $22.6 million, representing a 2.8% increase in property revenues as compared to the six months ended June 30, 2019. The following discussion describes the primary drivers of the decrease in net income available for MAA common shareholders for the six months ended June 30, 2020 as compared to the six months ended June 30, 2019.

Property Revenues

The following table reflects our property revenues by segment for the six months ended June 30, 2020 and 2019 (dollars in thousands):

	Six months ended June 30,
	2020		2019		Increase			% Increase
Same Store	$	782,256	$	758,293	$	23,963			3.2	%
Non-Same Store and Other		48,868		50,275		(1,407	)		(2.8	)%
Total	$	831,124	$	808,568	$	22,556			2.8	%

The increase in property revenues for our Same Store segment for the six months ended June 30, 2020 as compared to the six months ended June 30, 2019 was the primary driver of total property revenue growth. The Same Store segment generated a 3.2% increase in revenues for the six months ended June 30, 2020, primarily a result of average effective rent per unit growth of 3.8% as compared to the six months ended June 30, 2019. The decrease in property revenues from the Non-Same Store and Other segment for the six months ended June 30, 2020 as compared to six months ended June 30, 2019 was primarily the result of decreased revenues from our retail properties and from our exit from the Little Rock, Arkansas market during the fourth quarter of 2019.  These decreases were partially offset by increased revenues from recently completed development properties and 2019 multifamily acquisitions.  

Property Operating Expenses

Property operating expenses include costs for property personnel, building repairs and maintenance, real estate taxes and insurance, utilities, landscaping and other operating expenses. The following table reflects our property operating expenses by segment for the six months ended June 30, 2020 and 2019 (dollars in thousands):

	Six months ended June 30,
	2020		2019		Increase			% Increase
Same Store	$	290,256	$	282,439	$	7,817			2.8	%
Non-Same Store and Other		20,387		21,080		(693	)		(3.3	)%
Total	$	310,643	$	303,519	$	7,124			2.3	%

The increase in property operating expenses for our Same Store segment for the six months ended June 30, 2020 as compared to the six months ended June 30, 2019 was primarily driven by increases in real estate tax expense of $4.4 million, in addition to increases in marketing and insurance expenses.

Depreciation and Amortization

Depreciation and amortization expense for the six months ended June 30, 2020 was $253.6 million, an increase of $6.8 million as compared to the six months ended June 30, 2019. The increase was primarily driven by the recognition of depreciation expense associated with our development and redevelopment activities made after June 30, 2019 in the normal course of business through June 30, 2020.

32

Other Income and Expenses

Property management expenses for the six months ended June 30, 2020 were $26.4 million, a decrease of $0.9 million as compared to the six months ended June 30, 2019. General and administrative expenses for the six months ended June 30, 2020 were $23.8 million, an increase of $1.1 million as compared to the six months ended June 30, 2019.  

Interest expense for the six months ended June 30, 2020 was $85.6 million, a decrease of $6.0 million as compared to the six months ended June 30, 2019. The decrease was primarily due to decreased average daily debt outstanding as well as an increase in capitalized interest during the six months ended June 30, 2020 as compared to the six months ended June 30, 2019.  The increase in the capitalized interest expense was due to an increase in the number of development projects.  

During the six months ended June 30, 2019, we sold two land parcels resulting in a $9.3 million gain on sale of non-depreciable assets. No land parcels were sold during the six months ended June 30, 2020.

Other non-operating (income) expense for the six months ended June 30, 2020 was $13.9 million of expense, an increase of $18.6 million as compared to the six months ended June 30, 2019. The increase was primarily driven by $15.9 million of expense related to the fair value adjustment of the embedded derivative in the MAA Series I preferred shares during the six months ended June 30, 2020, compared to the recognition of $4.1 million of income related to the adjustment of the embedded derivative during the six months ended June 30, 2019. During the six months ended June 30, 2020, we also recognized $4.9 million of income from an unconsolidated limited partnership and $2.6 million of COVID-19 related expenses in other non-operating (income) expense. Our COVID-19 related expenses consisted primarily of additional cleaning supplies, contract labor and COVID-19 related leave.

Funds from Operations and Core Funds from Operations

Funds from operations, or FFO, a non-GAAP financial measure, represents net income available for MAA common shareholders (computed in accordance with the United States generally accepted accounting principles, or GAAP) excluding gains or losses on disposition of operating properties and asset impairment, plus depreciation and amortization of real estate assets, net income attributable to noncontrolling interests and adjustments for joint ventures. Because noncontrolling interest is added back, FFO, when used in this Quarterly Report on Form 10-Q, represents FFO attributable to the Company.

FFO should not be considered as an alternative to net income available for MAA common stockholders or any other GAAP measurement, as an indicator of operating performance or as an alternative to cash flow from operating, investing and financing activities as a measure of liquidity. Management believes that FFO is helpful to investors in understanding our operating performance, primarily because its calculation excludes depreciation and amortization expense on real estate assets. We believe that GAAP historical cost depreciation of real estate assets is generally not correlated with changes in the value of those assets, whose value does not diminish predictably over time, as historical cost depreciation implies. While our calculation of FFO is in accordance with the National Association of Real Estate Investment Trusts’, or NAREIT’s, definition, it may differ from the methodology for calculating FFO utilized by other REITs and, accordingly, may not be comparable to such other REITs.

Core FFO represents FFO as adjusted for items that are not considered part of our core business operations such as adjustments related to the fair value of the embedded derivative in the MAA Series I preferred shares, gain or loss on sale of non-depreciable assets, adjustments for gains or losses from unconsolidated limited partnerships, net casualty gain or loss, gain or loss on debt extinguishment, non-routine legal costs and settlements, COVID-19 related costs and mark-to-market debt adjustments. While our definition of Core FFO may be similar to others in the industry, our methodology for calculating Core FFO may differ from that utilized by other REITs and, accordingly, may not be comparable to such other REITs. Core FFO should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of operating performance. We believe that Core FFO is helpful in understanding our core operating performance between periods in that it removes certain items that by their nature are not comparable over periods and therefore tend to obscure actual operating performance.

The following table presents a reconciliation of net income available for MAA common shareholders to FFO and Core FFO for the three and six months ended June 30, 2020 and 2019, as we believe net income available for MAA common shareholders is the most directly comparable GAAP measure (dollars in thousands):

⁽³⁾ Non-recurring additional costs resulting from the COVID-19 pandemic, consisting primarily of additional cleaning supplies, contract labor and COVID-19 related leave.

⁽⁴⁾ Included in “Interest expense” in the Condensed Consolidated Statements of Operations.

Core FFO for the three months ended June 30, 2020 was $188.9 million, an increase of $8.0 million as compared to the three months ended June 30, 2019, primarily as a result of an increase in property revenues of $5.6 million, decreased interest expense of $3.8 million and decreased property management expenses of $1.7 million. The increases to Core FFO were offset by increases in property operating expenses, excluding depreciation and amortization, of $3.3 million and general and administrative expenses of $0.2 million.

Core FFO for the six months ended June 30, 2020 was $380.1 million, an increase of $21.9 million as compared to the six months ended June 30, 2019, primarily as a result of an increase in property revenues of $22.6 million, decreased interest expense of $6.0 million and decreased property management expenses of $0.9 million. The increases to Core FFO were offset by increases in property operating expenses, excluding depreciation and amortization, of $7.1 million and general and administrative expenses of $1.1 million.

Liquidity and Capital Resources

Our cash flows from operating, investing and financing activities, as well as general economic and market conditions, are the principal factors affecting our liquidity and capital resources.

Operating Activities

Net cash provided by operating activities was $389.6 million for the six months ended June 30, 2020 as compared to $368.5 million for the six months ended June 30, 2019.  The increase in operating cash flows was primarily driven by our operating performance.

34

Investing Activities

Net cash used in investing activities was $197.8 million for the six months ended June 30, 2020 as compared to $140.8 million for the six months ended June 30, 2019.  The primary drivers of the change were as follows (dollars in thousands):

	Primary drivers of cash (outflow) inflow
	during the six months ended June 30,						Increase (Decrease)
	2020			2019			in Net Cash
Purchases of real estate and other assets	$	(5,004	)	$	(19,596	)	$	14,592
Capital improvements, development and other		(191,850	)		(133,354	)		(58,496	)
Proceeds from disposition of real estate assets		660			14,640			(13,980	)

The decrease in cash outflows for purchases of real estate and other assets was driven by the acquisition activity during the six months ended June 30, 2020 as compared to the six months ended June 30, 2019.  The increase in cash outflows for capital improvements, development and other was primarily driven by increased development capital spend during the six months ended June 30, 2020 as compared to the six months ended June 30, 2019. The decrease in cash inflows related to proceeds from disposition of real estate assets was primarily due to the nature of the real estate assets sold during the six months ended June 30, 2020 as compared to the six months ended June 30, 2019.  

Financing Activities

Net cash used in financing activities was $226.7 million for the six months ended June 30, 2020 as compared to $221.6 million for the six months ended June 30, 2019.  The primary drivers of the change were as follows (dollars in thousands):

	Primary drivers of cash inflow (outflow)
	during the six months ended June 30,						Increase (Decrease)
	2020			2019			in Net Cash
Net change in revolving credit facility	$	—		$	(540,000	)	$	540,000
Net change in commercial paper		20,000			367,000			(347,000	)
Proceeds from notes payable		—			490,435			(490,435	)
Principal payments on notes payable		(3,483	)		(303,672	)		300,189
Dividends paid on common shares		(228,618	)		(218,758	)		(9,860	)

The decrease in cash outflows related to the net change in revolving credit facility resulted from no net borrowings during the six months ended June 30, 2020, as compared to the decrease in net borrowings of $540.0 million during the six months ended June 30, 2019.  The decrease in cash inflows related to the net change in commercial paper resulted from the increase in net borrowings of $20.0 million on our commercial paper program during the six months ended June 30, 2020, as compared to the increase of $367.0 million on our commercial paper program during the six months ended June 30, 2019.  The decrease in cash inflows related to proceeds from notes payable primarily resulted from the issuance of $300.0 million of senior notes and $191.3 million of property mortgages during the six months ended June 30, 2019; no such notes or mortgages were issued during the six months ended June 30, 2020.  The decrease in cash outflows from principal payments on notes payable primarily resulted from the retirement of a $300.0 million term loan during the six months ended June 30, 2019; no debt was retired during the six months ended June 30, 2020.  The increase in cash outflows from dividends paid on common shares primarily resulted from the increase in the dividend rate to $2.00 per share during the six months ended June 30, 2020, as compared to the dividend rate of $1.92 per share during the six months ended June 30, 2019.

Equity

As of June 30, 2020, MAA owned 114,365,203 OP Units, comprising a 96.6% limited partnership interest in MAALP, while the remaining 4,058,657 outstanding OP Units were held by limited partners of MAALP other than MAA.  Holders of OP Units (other than MAA) may require us to redeem their OP Units from time to time, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per OP Unit equal, in general, to the average closing price of MAA’s common stock on the NYSE over a specified period prior to the redemption date) or by delivering one share of MAA’s common stock (subject to adjustment under specified circumstances) for each OP Unit so redeemed.  In addition, MAA has registered under the Securities Act 4,058,657 shares of its common stock that, as of June 30, 2020, were issuable upon redemption of OP Units, in order for those shares to be sold freely in the public markets.

We have entered into separate distribution agreements with each of J.P. Morgan Securities LLC, BMO Capital Markets Corp. and KeyBanc Capital Markets Inc. to establish an ATM program allowing MAA to sell shares of its common stock from time to time into the existing market at current market prices or through negotiated transactions.  Under the ATM program, MAA has the authority to issue up to an aggregate of 4.0 million shares of its common stock, at such times to be determined by MAA.  The ATM program currently has a maturity of September 28, 2021.  MAA has no obligation to issue shares through the ATM program.

35

During the six months ended June 30, 2020 and 2019, MAA did not sell any shares of common stock under its ATM program. As of June 30, 2020, 3.9 million shares remained issuable under the ATM program.

Unsecured Revolving Credit Facility & Commercial Paper

In May 2019, MAALP closed on a $1.0 billion unsecured revolving credit facility with a syndicate of banks led by Wells Fargo Bank, National Association, or Wells Fargo, and fourteen other banks, which we refer to as the Credit Facility.  The Credit Facility replaced our previous unsecured revolving credit facility and includes an expansion option up to $1.5 billion.  The Credit Facility bears an interest rate of LIBOR, plus a spread of 0.75% to 1.45% based on an investment grade pricing grid.  The Credit Facility matures in May 2023 with an option to extend for two additional six-month periods.  As of June 30, 2020, there was no outstanding balance under the Credit Facility, while $3.1 million of capacity was used to support outstanding letters of credit.  The Credit Facility serves as our primary source of short-term liquidity.

In May 2019, MAALP established an unsecured commercial paper program, whereby it can issue unsecured commercial paper notes with varying maturities not to exceed 397 days up to a maximum aggregate amount outstanding of $500.0 million. As of June 30, 2020, there was $90.0 million outstanding under the commercial paper program.

Unsecured Senior Notes

As of June 30, 2020, we had $3.3 billion of publicly issued unsecured senior notes and $222.0 million of privately placed unsecured senior notes outstanding.

Unsecured Term Loan

As of June 30, 2020, we maintained one unsecured term loan with a syndicate of banks, led by Wells Fargo. The term loan has a balance of $300.0 million, matures in March 2022, and has a variable interest rate of LIBOR plus a spread of 0.90% to 1.75% based on the Company’s credit ratings. As of June 30, 2020, this loan was bearing interest at a rate of one month LIBOR plus 0.95%.

Secured Property Mortgages

We maintain secured property mortgages with the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation and various life insurance companies.  These mortgages are usually fixed rate and can range from five to 30 years in maturity.  As of June 30, 2020, we had $626.3 million of secured property mortgages with a weighted average interest rate of 4.50%.

For more information regarding our debt capital resources, see Note 6 to the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Off-Balance Sheet Arrangements

As of June 30, 2020 and 2019, we had an ownership interest in a limited liability company that owns one apartment community comprised of 269 units, located in Washington, D.C.  We also had ownership interests in two limited partnerships as of June 30, 2020. Our interests in these investments are unconsolidated and are recorded using the equity method as we do not have a controlling interest.

As of June 30, 2020 and 2019, we did not have any relationships, including those with unconsolidated entities or financial partnerships, for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.  In addition, we do not engage in trading activities involving non-exchange traded contracts.  As such, we are not materially exposed to

37

any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.  We do not have any relationships or transactions with persons or entities that derive benefits from their non-independent relationships with us or our related parties other than those disclosed in Note 12 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on February 20, 2020.

Insurance

We carry comprehensive general liability coverage on our apartment communities, with limits of liability we believe are customary within the multifamily apartment industry, to insure against liability claims and related defense costs. We also maintain insurance against the risk of direct physical damage to reimburse us on a replacement cost basis for costs incurred to repair or rebuild any property, including loss of rental income during the reconstruction period.

We renegotiated our insurance programs effective July 1, 2020. We believe that the current property and casualty insurance program in place provides appropriate insurance coverage for financial protection against insurable risks such that any insurable loss experienced that can be reasonably anticipated would not have a significant impact on our liquidity, financial position or results of operations.

Inflation

Our resident leases at our apartment communities allow, at the time of renewal, for adjustments in the rent payable thereunder, and thus may enable us to seek rent increases.  The majority of our leases are for one year or less. The short-term nature of these leases generally serves to reduce our risk to adverse effects of inflation.

Critical Accounting Policies and Estimates

Please refer to our Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on February 20, 2020, for discussions of our critical accounting policies.  During the six months ended June 30, 2020, there were no material changes to these policies.  For more information on recent accounting pronouncements that could have a material impact on our condensed consolidated financial statements see Note 1 to the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Item 3.Quantitative and Qualitative Disclosures About Market Risk.

Market risk includes risks that arise from changes in interest rates, foreign currency exchange rates, commodity prices, equity prices and other market changes that affect market sensitive instruments. Our primary market risk exposure is to changes in interest rates on our borrowings. As of June 30, 2020, 24.8% of our total market capitalization consisted of debt borrowings. Our interest rate risk objective is to limit the impact of interest rate fluctuations on earnings and cash flows and to lower our overall borrowing costs. To achieve this objective, we manage our exposure to fluctuations in market interest rates for borrowings through the use of fixed rate debt instruments and interest rate swaps, which mitigate our interest rate risk on a related financial instrument or on future refinancings. We use our best efforts to have our debt instruments mature across multiple years, which we believe limits our exposure to interest rate changes in any one year. We do not enter into derivative instruments for trading or other speculative purposes.  As of June 30, 2020, 91.3% of our outstanding debt was subject to fixed rates, and we did not have any outstanding interest rate swaps.  We regularly review interest rate exposure on outstanding borrowings in an effort to minimize the risk of interest rate fluctuations.  There have been no material changes in our market risk as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on February 20, 2020.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

In June 2016, plaintiffs Cathi Cleven and Tara Cleven, on behalf of a purported class of plaintiffs, filed a complaint against MAA and the Operating Partnership in the United States District Court for the Western District of Texas, Austin Division. In January 2017, Areli Arellano and Joe L. Martinez joined the lawsuit as additional plaintiffs. The lawsuit alleges that we (but not Post Properties (see the description of the Brown class action lawsuit below)) charged late fees at our Texas properties that violate Section 92.019 of the Texas Property Code, or Section 92.019, which provides that a landlord may not charge a tenant a late fee for failing to pay rent unless, among other things, the fee is a reasonable estimate of uncertain damages to the landlord that are incapable of precise calculation and result from the late payment of rent.  The plaintiffs are seeking monetary damages and attorneys’ fees and costs. In September 2018, the District Court certified a class proposed by the plaintiffs.  Additionally, in September 2018, the District Court denied our motion for summary judgment and granted the plaintiffs’ motion for partial summary judgment. Because the District Court certified a class prior to granting the plaintiffs’ motion for partial summary judgment, the District Court’s ruling applies to the entire class. In October 2018, the Fifth Circuit Court of Appeals accepted our petition to review the District Court’s order granting class certification.  In September 2019, the Fifth Circuit Court of Appeals heard our oral arguments.  We intend to appeal the District Court’s order granting plaintiff’s motion for summary judgment to the Fifth Circuit Court of Appeals if permission to appeal is granted. We will continue to vigorously defend the action and pursue such appeals.

In April 2017, plaintiff Nathaniel Brown, on behalf of a purported class of plaintiffs, filed a complaint against the Operating Partnership, as the successor by merger to Post Properties’ primary operating partnership, and MAA in the United States District Court for the Western District of Texas, Austin Division. The lawsuit alleges that Post Properties (and, following the Post Properties merger in December 2016, the Operating Partnership) charged late fees at its Texas properties that violate Section 92.019. The plaintiffs are seeking monetary damages and attorneys’ fees and costs. In September 2018, the District Court certified a class proposed by the plaintiff. Additionally, in September 2018, the District Court denied our motion for summary judgment and granted the plaintiff’s motion for partial summary judgment. Because the District Court certified a class prior to granting the plaintiff’s motion for partial summary judgment, the District Court’s ruling applies to the entire class. In October 2018, the Fifth Circuit Court of Appeals accepted our petition to review the District Court’s order granting class certification.  In September 2019, the Fifth Circuit Court of Appeals heard our oral arguments.  We intend to appeal the District Court’s order granting plaintiff’s motion for summary judgment to the Fifth Circuit Court of Appeals if permission to appeal is granted. We will continue to vigorously defend the action and pursue such appeals.

In addition, we are subject to various other legal proceedings arising in the course of our business operations. While no assurances can be given, we do not currently believe that any of these other outstanding matters will have a material adverse effect on our financial condition, results of operations or cash flows in the event of a negative outcome.

Item 1A. Risk Factors.

Other than the risk factor set forth below, there have been no material changes to the risk factors that were discussed in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on February 20, 2020.

The COVID-19 pandemic and mitigation efforts to control the spread of the disease have and are expected to continue to materially impact our business, and our financial condition, results of operations and cash flows could be materially adversely affected by factors relating to COVID-19.

In March 2020, the World Health Organization characterized COVID-19 as a pandemic, and the President of the United States proclaimed that the COVID-19 outbreak in the United States constituted a national emergency. Extraordinary actions were taken by federal, state and local governmental authorities to combat the spread of COVID-19, including issuance of “stay-at-home” directives and similar mandates for many individuals to substantially restrict daily activities and for many businesses to curtail or cease normal operations.  These measures, while intended to protect human life, led to significantly reduced economic activity and a surge in unemployment throughout the United States, including the markets where our properties are located. In April 2020, the national unemployment rate reached its highest level since the Great Depression, and in June 2020, the National Bureau of Economic Research officially declared that the United States had fallen into a recession. The duration and severity of this economic slowdown remain uncertain. Much of the Unites States economy is now in the process of reopening but, at the same time, the pandemic is intensifying in most areas of the country.  Accordingly, some jurisdictions have rolled back reopening plans, and more widespread reinstatement of directives and mandates requiring businesses to again curtail or cease normal operations remains a possibility. Additionally, the federal emergency unemployment benefit is scheduled to expire at end of July 2020, although state unemployment benefits may remain available.

Our ability to lease our apartments and collect rental revenues is dependent upon national, regional and local economic conditions, particularly unemployment levels and personal income levels.  As unemployment rises and incomes fall, fewer people, including both current and prospective residents, may be able to afford our apartment communities, and it may be difficult for some of our residents to make timely rental payments to us under their leases. To assist our residents who have lost wages or compensation due to the COVID-19 pandemic, we have offered these residents amendments to their leases that provided varying degrees of payment flexibility with respect to April, May, June and July 2020 rent and waived late fees and interest charges under the original lease for rent that was deferred under the lease amendment.  Whether we extend similar arrangements to defer rent will be determined in the future taking into account facts and circumstances at that particular time.

The ongoing COVID-19 pandemic and restrictions intended to prevent its spread could have significant adverse impacts on our business, financial condition, results of operations and cash flows that are difficult to predict. Such adverse impacts will depend on, among other factors:

• our residents’ ability or willingness to pay rent in full on a timely basis;

• federal, state, local and industry-initiated efforts that may adversely affect the ability of landlords, including us, to collect rent and customary fees, adjust rental rates and enforce remedies for the failure to pay rent;

• our ability to renew leases or relet units on favorable terms or at all, including as a result of unfavorable economic and market conditions in those markets where our apartment communities are located;

• our ability to lease or relet units due to social distancing or other restrictions intended to prevent the spread of COVID-19 that may frustrate our leasing activities;

• our ability to successfully complete the lease up of properties in our lease up portfolio and attain expected rental and occupancy rates on the originally anticipated schedule due to social distancing or other restrictions intended to prevent the spread of COVID-19 that may frustrate our leasing activities;

• our ability to complete the construction of properties in our development portfolio due to social distancing or other restrictions intended to prevent the spread of COVID-19 that may slow down or temporarily halt our construction activities;

• our ability to continue our apartment unit redevelopment programs and attain increased rental rates for renovated or upgraded units due to social distancing or other restrictions intended to prevent the spread of COVID-19;

• the possibility that one or more of our apartment communities could become a cluster site for COVID-19 infections, which could negatively impact our reputation and occupancy levels and result in operational losses due to reduced rental demand;

• severe and prolonged disruption and instability in the financial markets, including the debt and equity capital markets, which have already experienced and may continue to experience significant volatility, or deteriorations in credit and financing conditions (or a refusal or failure of one or more lenders under our unsecured revolving credit facility to fund their respective financing commitment to us), which may affect our ability to access capital necessary to fund our business operations or refinance maturing debt on a timely basis, on attractive terms or at all, which would adversely affect our ability to meet liquidity and capital expenditure requirements;

• sustained stock market volatility that negatively affects the market price of our securities, including market conditions unrelated to our operating performance or prospects; and

40

• our ability to manage our business to the extent our management or personnel are impacted in significant numbers by the COVID-19 pandemic and are not willing, available or allowed to conduct work.

The ongoing COVID-19 pandemic and the current economic, financial and capital markets environment present material risks and uncertainties for us.  However, the rapid development and fluidity of the situation precludes any prediction as to the ultimate impact COVID-19 will have on our business, financial condition, results of operation and cash flows, which will depend largely on future developments directly or indirectly relating to the duration and scope of the COVID-19 pandemic in the United States. To the extent the COVID-19 pandemic adversely affects our business, financial condition, results of operation and cash flows, it may also have the effect of heightening many of the other risks described in the “Risk Factors” section of our Annual Report on Form 10-K for the year ended December 31, 2019.

Consolidation And Basis Of Presentation And Significant Accounting Policies [Abstract]

Basis of Presentation and Principles of Consolidation and Significant Accounting Policies

1.Basis of Presentation and Principles of Consolidation and Significant Accounting Policies

Unless the context otherwise requires, all references to the “Company” refer collectively to Mid-America Apartment Communities, Inc., together with its consolidated subsidiaries, including Mid-America Apartments, L.P.  Unless the context otherwise requires, all references to “MAA” refer only to Mid-America Apartment Communities, Inc., and not any of its consolidated subsidiaries.  Unless the context otherwise requires, the references to the “Operating Partnership” or “MAALP” refer to Mid-America Apartments, L.P., together with its consolidated subsidiaries.  “Common stock” refers to the common stock of MAA and, unless the context otherwise requires, “shareholders” refers to the holders of shares of MAA’s common stock.  The common units of limited partnership interests in the Operating Partnership are referred to as “OP Units,” and the holders of the OP Units are referred to as “common unitholders”.

As of June 30, 2020, MAA owned 114,365,203 OP Units (or 96.6% of the total number of OP Units).  MAA conducts substantially all of its business and holds substantially all of its assets, directly or indirectly, through the Operating Partnership, and by virtue of its ownership of the OP Units and being the Operating Partnership’s sole general partner, MAA has the ability to control all of the day-to-day operations of the Operating Partnership.

Management believes combining the notes to the condensed consolidated financial statements of MAA and the Operating Partnership results in the following benefits:

• enhances a readers’ understanding of MAA and the Operating Partnership by enabling the reader to view the business as a whole in the same manner that management views and operates the business;

• eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the disclosure applies to both MAA and the Operating Partnership; and

• creates time and cost efficiencies through the preparation of one combined set of notes instead of two separate sets.

MAA, an S&P 500 company, is a multifamily-focused, self-administered and self-managed real estate investment trust, or REIT.  Management operates MAA and the Operating Partnership as one business. The management of the Company is comprised of individuals who are officers of MAA and employees of the Operating Partnership.  Management believes it is important to understand the few differences between MAA and the Operating Partnership in the context of how MAA and the Operating Partnership operate as a consolidated company.  MAA and the Operating Partnership are structured as an umbrella partnership REIT, or UPREIT. MAA’s interest in the Operating Partnership entitles MAA to share in cash distributions from, and in the profits and losses of, the Operating Partnership in proportion to MAA’s percentage interest therein and entitles MAA to vote on substantially all matters requiring a vote of the partners.  MAA’s only material asset is its ownership of limited partnership interests in the Operating Partnership (other than cash held by MAA from time to time); therefore, MAA’s primary function is acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing certain debt of the Operating Partnership. The Operating Partnership holds, directly or indirectly, all of the Company’s real estate assets.  Except for net proceeds from public equity issuances by MAA, which are contributed to the Operating Partnership in exchange for limited partnership interests, the Operating Partnership generates the capital required by the business through the Operating Partnership’s operations, direct or indirect incurrence of indebtedness and issuance of OP Units.

The presentations of MAA’s shareholders’ equity and the Operating Partnership’s capital are the principal areas of difference between the condensed consolidated financial statements of MAA and those of the Operating Partnership.  MAA’s shareholders’ equity may include shares of preferred stock, shares of common stock, additional paid-in capital, cumulative earnings, cumulative distributions, noncontrolling interest, treasury shares, accumulated other comprehensive income and redeemable common stock.  The Operating Partnership’s capital may include common capital and preferred capital of the general partner (MAA), limited partners’ common capital and preferred capital, noncontrolling interest, accumulated other comprehensive income and redeemable common units.  Holders of OP Units (other than MAA) may require the Operating Partnership to redeem their OP Units from time to time, in which case the Operating Partnership may, at its option, pay the redemption price either in cash (in an amount per OP Unit equal, in general, to the average closing price of MAA’s common stock on the New York Stock Exchange, or NYSE, over a specified period prior to the redemption date) or by delivering one share of MAA’s common stock (subject to adjustment under specified circumstances) for each OP Unit so redeemed.

Organization of Mid-America Apartment Communities, Inc.

The Company owns, operates, acquires and selectively develops apartment communities primarily located in the Southeast, Southwest and Mid-Atlantic regions of the United States.  As of June 30, 2020, the Company owned and operated 299 apartment communities through the Operating Partnership and its subsidiaries and had an ownership interest in one apartment community through an unconsolidated real estate joint venture.  As of June 30, 2020, the Company had six development communities under construction totaling 1,940 apartment units once complete.  Total expected costs for the six development projects are $459.5 million, of which $215.8 million had been incurred through June 30, 2020.  MAA expects to complete one of these developments in 2020, four

developments in 2021 and one development in 2022. As of June 30, 2020, thirty-two of the Company’s apartment communities included retail components with approximately 630,000 square feet of gross leasable space.  In addition, as of June 30, 2020, the Company had four commercial properties with approximately 260,000 square feet of combined gross leasable area.  The Company’s apartment communities and commercial properties were located across 16 states and the District of Columbia as of June 30, 2020.

Basis of Presentation and Principles of Consolidation

The accompanying condensed consolidated financial statements have been prepared by the Company’s management in accordance with United States generally accepted accounting principles, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or the SEC.  The condensed consolidated financial statements of MAA presented herein include the accounts of MAA, the Operating Partnership and all other subsidiaries in which MAA has a controlling financial interest. MAA owns, directly or indirectly, approximately 80% to 100% of all consolidated subsidiaries, including the Operating Partnership.  The condensed consolidated financial statements of MAALP presented herein include the accounts of MAALP and all other subsidiaries in which MAALP has a controlling financial interest.  MAALP owns, directly or indirectly, 80% to 100% of all consolidated subsidiaries.  In management’s opinion, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included, and all such adjustments were of a normal recurring nature.  All significant intercompany accounts and transactions have been eliminated in consolidation.

The Company invests in entities which may qualify as variable interest entities, or VIEs, and MAALP is considered a VIE.  A VIE is a legal entity in which the equity investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the holders of the equity investment at risk lack the power to direct the activities of a legal entity as well as the obligation to absorb its expected losses or the right to receive its expected residual returns.  MAALP is classified as a VIE, because the limited partners lack substantive kick-out rights and substantive participating rights.  The Company consolidates all VIEs for which it is the primary beneficiary and uses the equity method to account for investments that qualify as VIEs but for which it is not the primary beneficiary.  In determining whether the Company is the primary beneficiary of a VIE, management considers both qualitative and quantitative factors, including, but not limited to, those activities that most significantly impact the VIE’s economic performance and which party controls such activities.  The Company uses the equity method of accounting for its investments in entities for which the Company exercises significant influence, but does not have the ability to exercise control.  The factors considered in determining whether the Company has the ability to exercise control include ownership of voting interests and participatory rights of investors (see “Investments in Unconsolidated Affiliates” below).

Reclassifications

In order to present comparative financial statements, certain reclassifications have been made to the Condensed Consolidated Statements of Operations. Prior year amounts have been changed to conform to the Company’s current year presentation.  As a result of these reclassifications, $0.2 million and $1.0 million of expenses previously reported as “General and administrative expenses” for the three and six months ended June 30, 2019, respectively, have been reclassified to the “Other non-operating (income) expense” line item of the Condensed Consolidated Statements of Operations in this report.

Noncontrolling Interests

As of June 30, 2020, the Company had two types of noncontrolling interests with respect to its consolidated subsidiaries, (1) noncontrolling interests related to the common unitholders of its Operating Partnership and (2) noncontrolling interests related to its consolidated real estate entities.  The noncontrolling interests relating to the limited partnership interests in the Operating Partnership are owned by the holders of the Class A OP Units. MAA is the sole general partner of the Operating Partnership and holds all of the outstanding Class B OP Units. Net income (after allocations to preferred ownership interests) is allocated to MAA and the noncontrolling interests based on their respective ownership percentages of the Operating Partnership. Issuance of additional Class A OP Units or Class B OP Units changes the ownership percentage of both the noncontrolling interests and MAA. The issuance of Class B OP Units generally occurs when MAA issues common stock and the issuance proceeds are contributed to the Operating Partnership in exchange for Class B OP Units equal to the number of shares of MAA’s common stock issued. At each reporting period, the allocation between total MAA shareholders’ equity and noncontrolling interests is adjusted to account for the change in the respective percentage ownership of the underlying equity of the Operating Partnership. MAA’s Board of Directors established economic rights in respect to each Class A OP Unit that were equivalent to the economic rights in respect to each share of MAA common stock. See Note 9 for additional details.

The noncontrolling interests relating to the Company’s two consolidated real estate entities are owned by private real estate companies that are generally responsible for the development and construction of the apartment communities that are owned through the consolidated real estate entities with a noncontrolling interest.  The entities were determined to be VIE’s with the Company designated as the primary beneficiary.  As a result, the accounts of the entities are consolidated by the Company.  As of June 30, 2020, the consolidated assets and liabilities of the Company’s consolidated real estate entities with a noncontrolling interest were $77.2 million and $8.4 million, respectively.  As of December 31, 2019, the consolidated assets and liabilities of the Company’s consolidated real estate entities with a noncontrolling interest were $46.0 million and $3.2 million, respectively.

Investments in Unconsolidated Affiliates

The Company uses the equity method to account for its investments in a real estate joint venture and two technology-focused limited partnerships that qualify as a VIE. Management determined the Company is not the primary beneficiary in any of these investments but does have the ability to exert significant influence over the operations and financial policies of the real estate joint venture and considers its investment in the limited partnerships to be more than minor. The Company’s investment in the real estate joint venture was $43.6 million and $43.7 million as of June 30, 2020 and December 31, 2019, respectively.

As of June 30, 2020 and December 31, 2019, the Company’s investments in the technology-focused limited partnerships were $19.7 million and $13.1 million, respectively, and are included in “Other assets” in the accompanying Condensed Consolidated Balance Sheets. As of June 30, 2020, the Company was committed until February 2025 to make additional capital contributions totaling $23.0 million if and when called by the general partners of the limited partnerships.

Fair Value Measurements

The Company applies the guidance in Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, to the valuation of real estate assets recorded at fair value, to its impairment valuation analysis of real estate assets, to its disclosure of the fair value of financial instruments, principally indebtedness and to its derivative financial instruments.  Fair value disclosures required under ASC Topic 820 as well as the Company’s derivative accounting policies are summarized in Note 7 utilizing the following hierarchy:

Level 1 - Quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date.

Level 2 - Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly.

Level 3 - Unobservable inputs for the assets or liability.

Revenue Recognition

The Company primarily leases multifamily residential apartments to residents under operating leases generally due on a monthly basis with terms of approximately one year or less.  Rental revenues are recognized in accordance with ASC Topic 842, Leases, using a method that represents a straight-line basis over the term of the lease. In addition, in circumstances where a lease incentive is provided to tenants, the incentive is recognized as a reduction of rental revenues on a straight-line basis over the reasonably assured lease term.  Rental revenues represent approximately 93% of the Company’s total revenues and include gross rents charged less adjustments for concessions and bad debt.  Approximately 6% of the Company’s total revenues represent non-lease reimbursable property revenues from its residents for utility reimbursements, which are generally recognized and due on a monthly basis as residents obtain control of the service over the term of the lease.  The remaining 1% of the Company’s total revenues represents other non-lease property revenues primarily driven by nonrefundable fees and commissions.

In accordance with ASC Topic 842, rental revenues and non-lease reimbursable property revenues meet the criteria to be aggregated into a single lease component and are reported on a combined basis in the line item “Rental revenues”, as presented in the disaggregation of the Company’s revenues in Note 11.  Other non-lease property revenues are accounted for in accordance with ASC Topic 606, Revenue from Contracts with Customers, which requires revenue recognized outside of the scope of ASC Topic 842 to be recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. Other non-lease property revenues are reported in the line item “Other property revenues”, as presented in the disaggregation of the Company’s revenues in Note 11.

Leases

The Company is the lessee under certain ground, office, equipment and other operational leases, all of which are accounted for as operating leases in accordance with ASC Topic 842. The Company recognizes a right-of-use asset for the right to use the underlying asset for all leases where the Company is the lessee with terms of more than twelve months, and a related lease liability for the obligation to make lease payments. Expenses related to leases determined to be operating leases are recognized on a straight-line basis.  As of June 30, 2020 and December 31, 2019, right-of-use assets recorded within “Other assets” totaled $50.6 million and $53.8 million, respectively, and related lease obligations recorded within “Accrued expenses and other liabilities” totaled $32.5 million and $33.1 million, respectively, in the Condensed Consolidated Balance Sheets.  As of June 30, 2020, the Company’s operating leases had a weighted average remaining lease term of approximately 31 years and a weighted average discount rate of approximately 4.4%. Lease expense recognized for the three and six months ended June 30, 2020 and 2019 was immaterial to the Company. Cash paid for amounts included in the measurement of operating lease liabilities during the six months ended June 30, 2020 and 2019 was also immaterial.

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Measurement of Credit Losses on Financial Instruments, which amends the current approach to estimate credit losses on certain financial assets, including trade and other receivables, available-for-sale securities and other financial instruments.  The ASU requires entities to estimate a lifetime expected credit loss for most financial instruments, including trade receivables.  Subsequent changes in the valuation allowance are recorded in current earnings and reversal of previous losses is permitted.  In November 2018, the FASB issued an amendment excluding operating lease receivables accounted for under ASC Topic 842 from the scope of the new credit losses standard. The Company adopted the standard on January 1, 2020. The adoption of ASU No. 2016-13 did not result in significant changes in the accounting for the Company’s approach to estimate credit losses on financial assets, as substantially all of the Company’s financial assets are operating lease receivables.

2.Earnings per Common Share of MAA

Basic earnings per share is computed by dividing net income available to MAA common shareholders by the weighted average number of common shares outstanding during the period.  All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per share.  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 with diluted earnings per share being the more dilutive of the treasury stock or two-class methods.  OP Units are included in dilutive earnings per share calculations when the units are dilutive to earnings per share.

For the three and six months ended June 30, 2020 and 2019, MAA’s diluted earnings per share was computed using the treasury stock method as presented below (dollars and shares in thousands, except per share amounts):

Earnings Per Share [Abstract]

Earnings per OP Unit of MAALP

3.Earnings per OP Unit of MAALP

Basic earnings per common unit is computed by dividing net income available for common unitholders by the weighted average number of OP Units outstanding during the period.  All outstanding unvested restricted unit awards contain rights to non-forfeitable distributions and participate in undistributed earnings with common unitholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per common unit.  Diluted earnings per common unit reflects the potential dilution that could occur if securities or other contracts to issue OP Units were exercised or converted into OP Units.  Both the unvested restricted unit awards and other potentially dilutive common units, and the related impact to earnings, are considered when calculating earnings per common unit on a diluted basis with diluted earnings per common unit being the more dilutive of the treasury stock or two-class methods.

For the three and six months ended June 30, 2020 and 2019, MAALP’s diluted earnings per common unit was computed using the treasury stock method as presented below (dollars and units in thousands, except per unit amounts):

In May 2019, MAALP entered into a $1.0 billion unsecured revolving credit facility with a syndicate of banks led by Wells Fargo Bank, National Association, or Wells Fargo, and fourteen other banks, which is referred to as the Credit Facility.  The Credit Facility replaced MAALP’s previous unsecured revolving credit facility, and it includes an expansion option up to $1.5 billion.  The Credit Facility bears an interest rate of the London Interbank Offered Rate, or LIBOR, plus a spread of 0.75% to 1.45% based on an investment grade pricing grid. The Credit Facility matures in May 2023 with an option to extend for two additional six-month periods.  As of June 30, 2020, there was no outstanding balance under the Credit Facility, while $3.1 million of capacity was used to support outstanding letters of credit.

Unsecured Commercial Paper

In May 2019, MAALP established an unsecured commercial paper program whereby MAALP may issue unsecured commercial paper notes with varying maturities not to exceed 397 days up to a maximum aggregate principal amount outstanding of $500.0 million.  As of June 30, 2020, MAALP had $90.0 million outstanding under the commercial paper program. For the three months ended June 30, 2020, the average daily borrowings outstanding under the commercial paper program were $65.0 million.  

Unsecured Senior Notes

As of June 30, 2020, MAALP had $3.3 billion of publicly issued unsecured senior notes outstanding and $222.0 million of privately placed unsecured senior notes outstanding.  The unsecured senior notes had maturities at issuance ranging from ten to twelve years, with a weighted average of 6.1 years remaining until maturity as of June 30, 2020.

Unsecured Term Loan

As of June 30, 2020, MAALP maintained one term loan with a syndicate of banks led by Wells Fargo. The term loan has a balance of $300.0 million and matures in March 2022.  The term loan has a variable interest rate of LIBOR plus a spread of 0.90% to 1.75% based on the Company’s credit ratings.      

Secured Property Mortgages

As of June 30, 2020, MAALP had $626.3 million of fixed rate conventional property mortgages with a weighted average interest rate of 4.50% and a weighted average maturity in 2037.

Fair Value Disclosures [Abstract]

Financial Instruments and Derivatives

7.Financial Instruments and Derivatives

Financial Instruments Not Carried at Fair Value

Cash and cash equivalents, restricted cash and accrued expenses and other liabilities are carried at amounts that reasonably approximate their fair value due to their short term nature.

Fixed rate notes payable as of June 30, 2020 and December 31, 2019, totaled $4.1 billion and had estimated fair values of $4.6 billion and $4.5 billion (excluding prepayment penalties) as of June 30, 2020 and December 31, 2019, respectively. The carrying values of variable rate debt (excluding the effect of interest rate swap agreements) as of June 30, 2020 and December 31, 2019, totaled $0.4 billion and had estimated fair values of $0.4 billion (excluding prepayment penalties) as of June 30, 2020 and December 31, 2019. The fair values of fixed rate debt are determined by using the present value of future cash outflows discounted with the applicable current market rate plus a credit spread. The fair values of variable rate debt are determined using the stated variable rate plus the current market credit spread. The variable rates reset every 30 to 90 days, and management concluded these rates reasonably estimate current market rates.

Financial Instruments Measured at Fair Value on a Recurring Basis

As of June 30, 2020, the Company had one outstanding series of cumulative redeemable preferred stock, which is referred to as the MAA Series I preferred stock (see Note 8).  The Company has recognized a derivative asset related to the redemption feature embedded in the MAA Series I preferred stock. The derivative asset is valued using widely accepted valuation techniques, including a discounted cash flow analysis in which the perpetual value of the preferred shares is compared to the value of the preferred shares assuming the call option is exercised, with the value of the bifurcated call option as the difference between the two values. The analysis reflects the contractual terms of the redeemable preferred shares, which are redeemable at the Company’s option beginning on October 1, 2026 and at the redemption price of $50.00 per share. The Company uses various inputs in the analysis, including trading data available on the preferred shares, coupon yields on preferred stock issuances from REITs with similar credit ratings as MAA and treasury rates to determine the fair value of the bifurcated call option.

The redemption feature embedded in the MAA Series I preferred stock is reported as a derivative asset in “Other assets” in the accompanying Condensed Consolidated Balance Sheets and is adjusted to its fair value at each reporting date, with a corresponding non-cash adjustment to “Other non-operating (income) expense” in the accompanying Condensed Consolidated Statements of Operations.  As a result of adjustments of non-cash expense recorded to reflect the change in fair value of the derivative asset during the six months ended June 30, 2020, the fair value of the embedded derivative asset decreased to $20.5 million as of June 30, 2020 as compared to $36.5 million as of December 31, 2019.

Periodically, the Company uses interest rate swaps to add stability to interest expense and to manage, or hedge, its exposure to interest rate movements associated with anticipated future debt transactions and variable rate debt. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.

Management incorporates credit valuation adjustments to appropriately reflect both its nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of the derivative contracts for the effect of nonperformance risk, the Company considers the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Based on guidance issued by the FASB, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.

As of June 30, 2020, the Company did not have any outstanding interest rate derivatives designated as cash flow hedges of interest rate risk. The fair value of interest rate derivative contracts designated as hedging instruments recorded in “Other assets” in the accompanying Condensed Consolidated Balance Sheets as of December 31, 2019 was $0.1 million.  The Company’s interest rate derivative contracts designated as hedging instruments and their related gains and losses are reported in “Net change in operating accounts and other operating activities” in the accompanying Condensed Consolidated Statements of Cash Flows.

The Company has determined the majority of the inputs used to value its outstanding debt and its embedded derivative fall within Level 2 of the fair value hierarchy, and as a result, the fair value valuation of its debt and embedded derivative held as of June 30, 2020 and December 31, 2019 were classified as Level 2 in the fair value hierarchy.

Cash Flow Hedges of Interest Rate Risk

The changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in “Accumulated other comprehensive loss” and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. As long as a hedging instrument is designated and the results of the effectiveness testing support that the instrument qualifies

for hedge accounting treatment, there is no periodic measurement or recognition of ineffectiveness. Rather, the full impact of hedge gains and losses is recognized in the period in which hedged transactions impact earnings, regardless of whether or not economic mismatches exist in the hedging relationship.  Amounts reported in “Accumulated other comprehensive loss” related to derivatives designated as qualifying cash flow hedges are reclassified to interest expense as interest payments are made on the Company’s variable rate or fixed rate debt. During the next twelve months, the Company estimates that an additional $1.1 million will be reclassified to earnings as an increase to “Interest expense”, which primarily represents the difference between the fixed interest rate swap payments and the projected variable interest rate swap receipts.

Partners' Capital of MAALP

Partners Capital Notes [Abstract]

Partners' Capital of MAALP

9.Partners’ Capital of MAALP

Common units of limited partnership interests in MAALP are represented by OP Units.  As of June 30, 2020, there were 118,423,860 OP Units outstanding, 114,365,203, or 96.6%, of which represent Class B OP Units (common units issued to or held by MAALP’s general partner or any of its subsidiaries), which were owned by MAA, MAALP’s general partner.  The remaining 4,058,657 OP Units were Class A OP Units owned by Class A limited partners.  As of June 30, 2019, there were 118,133,172 OP Units outstanding, 114,043,089, or 96.5%, of which were owned by MAA and 4,090,083 of which were owned by the Class A limited partners.

MAA, as the sole general partner of MAALP, has full, complete and exclusive discretion to manage and control the business of MAALP subject to the restrictions specifically contained within MAALP’s agreement of limited partnership, or the Partnership Agreement.  Unless otherwise stated in the Partnership Agreement, this power includes, but is not limited to, acquiring, leasing or disposing of any real property; constructing buildings and making other improvements to properties owned; borrowing money, modifying or extinguishing current borrowings, issuing evidence of indebtedness and securing such indebtedness by mortgage, deed of trust, pledge or other lien on MAALP’s assets; and distribution of MAALP’s cash or other assets in accordance with the Partnership Agreement.  MAA can generally, at its sole discretion, issue and redeem OP Units and determine the consideration to be received or the redemption price to be paid, as applicable.  The general partner may delegate these and other powers granted if the general partner remains in supervision of the designee.

Under the Partnership Agreement, MAALP may issue Class A OP Units and Class B OP Units.  Class A OP Units are any OP Units other than Class B OP Units, while Class B OP Units are those issued to or held by MAALP’s general partner or any of its subsidiaries.  In general, the limited partners do not have the power to participate in the management or control of MAALP’s business except in limited circumstances, including changes in the general partner and protective rights if the general partner acts outside of the provisions provided in the Partnership Agreement.  The transferability of Class A OP Units is also limited by the Partnership Agreement.

Net income of MAALP (after allocations to preferred ownership interests) is allocated to the general partner and limited partners based on their respective ownership percentages of MAALP.  Issuance or redemption of additional Class A OP Units or Class B OP Units changes the relative ownership percentage of the partners.  The issuance of Class B OP Units generally occurs when MAA issues common stock and the proceeds from that issuance are contributed to MAALP in exchange for the issuance to MAA of a number of OP Units equal to the number of shares of common stock issued.  Likewise, if MAA repurchases or redeems outstanding shares of common stock, MAALP generally redeems an equal number of Class B OP Units with similar terms held by MAA for a redemption price equal to the purchase price of those shares of common stock.  At each reporting period, the allocation between general partner capital and limited partner capital is adjusted to account for the change in the respective percentage ownership of the underlying capital of MAALP.  Holders of the Class A OP Units may require MAA to redeem their Class A OP Units, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per Class A OP Unit equal, in general, to the average closing price of MAA’s common stock on the NYSE over a specified period prior to the redemption date) or by delivering one share of MAA common stock (subject to adjustment under specified circumstances) for each Class A OP Unit so redeemed.

As of June 30, 2020, a total of 4,058,657 Class A OP Units were outstanding and redeemable for 4,058,657 shares of MAA common stock, with an approximate value of $465.4 million, based on the closing price of MAA’s common stock on June 30, 2020 of $114.67 per share.  As of June 30, 2019, a total of 4,090,083 Class A OP Units were outstanding and redeemable for 4,090,083 shares of MAA common stock, with an approximate value of $481.6 million, based on the closing price of MAA’s common stock on June 28, 2019 of $117.76 per share.  MAALP pays the same per unit distributions in respect to the OP Units as the per share dividends MAA pays in respect to its common stock.

As of June 30, 2020, MAALP had one outstanding series of cumulative redeemable preferred units, or the MAALP Series I preferred units.  The MAALP Series I preferred units have the same characteristics as the MAA Series I preferred stock described in Note 8.  As of June 30, 2020, 867,846 units of the MAALP Series I preferred units were outstanding.

Leases

The Company’s leases include a ground lease expiring in 2074 related to one of its apartment communities and an office lease expiring in 2028 related to its corporate headquarters.  Both leases contain stated rent increases that generally compensate for the impact of inflation.  The Company also has other commitments related to immaterial office and equipment operating leases.

Legal Proceedings

In June 2016, plaintiffs Cathi Cleven and Tara Cleven, on behalf of a purported class of plaintiffs, filed a complaint against MAA and the Operating Partnership in the United States District Court for the Western District of Texas, Austin Division.  In January 2017, Areli Arellano and Joe L. Martinez joined the lawsuit as additional plaintiffs.  The lawsuit alleges that the Company (but not Post Properties (see the description of the Brown class action lawsuit below)) charged late fees at its Texas properties that violate Section 92.019 of the Texas Property Code, or Section 92.019, which provides that a landlord may not charge a tenant a late fee for failing to pay rent unless, among other things, the fee is a reasonable estimate of uncertain damages to the landlord that are incapable of precise calculation and result from the late payment of rent.  The plaintiffs are seeking monetary damages and attorneys’ fees and costs.  In September 2018, the District Court certified a class proposed by the plaintiffs. Additionally, in September 2018, the District Court denied the Company’s motion for summary judgment and granted the plaintiffs’ motion for partial summary judgment.  Because the District Court certified a class prior to granting the plaintiffs’ motion for partial summary judgment, the District Court’s ruling applies to the entire class.  In October 2018, the Fifth Circuit Court of Appeals accepted the Company’s petition to review the District Court’s order granting class certification.  In September 2019, the Fifth Circuit Court of Appeals heard the Company’s oral arguments. The Company also intends to appeal the District Court’s order granting plaintiff’s motion for summary judgment to the Fifth Circuit Court of Appeals if permission to appeal is granted.  The Company will continue to vigorously defend the action and pursue such appeals.  Management estimates that the Company’s maximum exposure in the lawsuit, given the class certification and summary judgment ruling, is $54.6 million, which includes both potential damages and attorneys’ fees but excludes any prejudgment interest that may be awarded.

In April 2017, plaintiff Nathaniel Brown, on behalf of a purported class of plaintiffs, filed a complaint against the Operating Partnership, as the successor by merger to Post Properties’ primary operating partnership, and MAA in the United States District Court for the Western District of Texas, Austin Division.  The lawsuit alleges that Post Properties (and, following the Post Properties merger in December 2016, the Operating Partnership) charged late fees at its Texas properties that violate Section 92.019.  The plaintiffs are seeking monetary damages and attorney’s fees and costs.  In September 2018, the District Court certified a class proposed by the plaintiff.  Additionally, in September 2018, the District Court denied the Company’s motion for summary judgment and granted the plaintiff’s motion for partial summary judgment. Because the District Court certified a class prior to granting the plaintiff’s motion for partial summary judgment, the District Court’s ruling applies to the entire class.  In October 2018, the Fifth Circuit Court of Appeals accepted the Company’s petition to review the District Court’s order granting class certification. In September 2019, the Fifth Circuit Court of Appeals heard the Company’s oral arguments. The Company also intends to appeal the District Court’s order granting plaintiff’s motion for summary judgment to the Fifth Circuit Court of Appeals if permission to appeal is granted.  The Company will continue to vigorously defend the action and pursue such appeals.  Management estimates that the Company’s maximum exposure in the lawsuit, given the class certification and summary judgment ruling, is $8.4 million, which includes both potential damages and attorneys’ fees but excludes any prejudgment interest that may be awarded.

The Company is subject to various other legal proceedings and claims that arise in the ordinary course of its business operations.  Matters which arise out of allegations of bodily injury, property damage and employment practices are generally covered by insurance.  While the resolution of these other matters cannot be predicted with certainty, management does not currently believe that such matters, either individually or in the aggregate, will have a material adverse effect on the Company’s financial condition, results of operations or cash flows in the event of a negative outcome.

Loss Contingencies

The outcomes of claims, disputes and legal proceedings are subject to significant uncertainty.  The Company records an accrual for loss contingencies when a loss is probable and the amount of the loss can be reasonably estimated.  The Company also accrues an estimate of defense costs expected to be incurred in connection with legal matters.  Management reviews these accruals quarterly and makes revisions based on changes in facts and circumstances.  When a loss contingency is not both probable and reasonably estimable, management does not accrue the loss. However, if the loss (or an additional loss in excess of the accrual) is at least a reasonable possibility and material, then management discloses a reasonable estimate of the possible loss, or range of loss, if such reasonable estimate can be made.  If the Company cannot make a reasonable estimate of the possible loss, or range of loss, then a statement to that effect is disclosed.

The assessment of whether a loss is probable or a reasonable possibility, and whether the loss or range of loss is reasonably estimable, often involves a series of complex judgments about future events.  Among the factors considered in this assessment, are the nature of existing legal proceedings and claims, the asserted or possible damages or loss contingency (if reasonably estimable), the progress of the matter, existing law and precedent, the opinions or views of legal counsel and other advisers, management’s experience in similar matters, the facts available to management at the time of assessment, and how the Company intends to respond, or has responded, to the proceeding or claim.  Management’s assessment of these factors may change over time as individual proceedings or claims progress.  For matters where management is not currently able to reasonably estimate a range of reasonably possible loss, the factors that have contributed to this determination include the following: (i) the damages sought are indeterminate; (ii) the proceedings are in the early stages; (iii) the matters involve novel or unsettled legal theories or a large or uncertain number of actual or potential cases or parties; and/or (iv) discussions with the parties in matters that are ultimately expected to be resolved through negotiation and settlement have not reached the point where management believes a reasonable estimate of loss, or range of loss, can be made.  The Company believes that there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss or business impact, if any.

As of June 30, 2020 and December 31, 2019, the Company’s accrual for loss contingencies relating to unresolved legal matters was $8.5 million and $8.6 million in the aggregate, respectively.  The loss contingencies are presented in “Accrued expenses and other liabilities” in the accompanying Condensed Consolidated Balance Sheets.

Notes To Financial Statements [Abstract]

Segment Information

11.Segment Information

As of June 30, 2020, the Company owned and operated 299 multifamily apartment communities in 16 different states from which it derived all significant sources of earnings and operating cash flows.  The Company views each consolidated apartment community as an operating segment. The Company’s chief operating decision maker, which is the Company’s Chief Executive Officer, evaluates performance and determines resource allocations of each of the apartment communities on a Same Store and Non-Same Store and Other basis, as well as an individual apartment community basis. This is consistent with the aggregation criteria under GAAP as each of the apartment communities generally has similar economic characteristics, facilities, services, and tenants.

The following reflects the two reportable segments for the Company:

• Same Store communities are communities that the Company has owned and have been stabilized for at least a full 12 months.

• Non-Same Store and Other includes recently acquired communities, communities in development or lease-up, communities that have been identified for disposition, communities that have incurred a significant casualty loss and stabilized communities that do not meet the requirements to be Same Store communities. Also included in Non-Same Store and Other are non-multifamily activities.

On the first day of each calendar year, the Company determines the composition of its Same Store and Non-Same Store and Other reportable segments for that year as well as adjusts the previous year, which allows the Company to evaluate full period-over-period operating comparisons.  Properties in development or lease-up are added to the Same Store portfolio on the first day of the calendar year after a community has been owned and stabilized for at least a full 12 months.  Communities are considered stabilized after achieving 90% occupancy for 90 days.  Communities that have been identified for disposition are excluded from the Same Store portfolio.

The chief operating decision maker utilizes net operating income, or NOI, in evaluating the performance of its operating segments.  Total NOI represents total property revenues less total property operating expenses, excluding depreciation and amortization, for all properties held during the period regardless of their status as held for sale.  Management believes that NOI is a helpful tool in evaluating the operating performance of the segments because it measures the core operations of property performance by excluding corporate level expenses and other items not directly related to property operating performance.

Revenues and NOI for each reportable segment for the three and six months ended June 30, 2020 and 2019 were as follows (in thousands):

Accounting Policies [Abstract]

Basis of Presentation and Principles of Consolidation

Basis of Presentation and Principles of Consolidation

The accompanying condensed consolidated financial statements have been prepared by the Company’s management in accordance with United States generally accepted accounting principles, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or the SEC.  The condensed consolidated financial statements of MAA presented herein include the accounts of MAA, the Operating Partnership and all other subsidiaries in which MAA has a controlling financial interest. MAA owns, directly or indirectly, approximately 80% to 100% of all consolidated subsidiaries, including the Operating Partnership.  The condensed consolidated financial statements of MAALP presented herein include the accounts of MAALP and all other subsidiaries in which MAALP has a controlling financial interest.  MAALP owns, directly or indirectly, 80% to 100% of all consolidated subsidiaries.  In management’s opinion, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included, and all such adjustments were of a normal recurring nature.  All significant intercompany accounts and transactions have been eliminated in consolidation.

The Company invests in entities which may qualify as variable interest entities, or VIEs, and MAALP is considered a VIE.  A VIE is a legal entity in which the equity investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the holders of the equity investment at risk lack the power to direct the activities of a legal entity as well as the obligation to absorb its expected losses or the right to receive its expected residual returns.  MAALP is classified as a VIE, because the limited partners lack substantive kick-out rights and substantive participating rights.  The Company consolidates all VIEs for which it is the primary beneficiary and uses the equity method to account for investments that qualify as VIEs but for which it is not the primary beneficiary.  In determining whether the Company is the primary beneficiary of a VIE, management considers both qualitative and quantitative factors, including, but not limited to, those activities that most significantly impact the VIE’s economic performance and which party controls such activities.  The Company uses the equity method of accounting for its investments in entities for which the Company exercises significant influence, but does not have the ability to exercise control.  The factors considered in determining whether the Company has the ability to exercise control include ownership of voting interests and participatory rights of investors (see “Investments in Unconsolidated Affiliates” below).

Reclassifications

Reclassifications

In order to present comparative financial statements, certain reclassifications have been made to the Condensed Consolidated Statements of Operations. Prior year amounts have been changed to conform to the Company’s current year presentation.  As a result of these reclassifications, $0.2 million and $1.0 million of expenses previously reported as “General and administrative expenses” for the three and six months ended June 30, 2019, respectively, have been reclassified to the “Other non-operating (income) expense” line item of the Condensed Consolidated Statements of Operations in this report.

Noncontrolling Interests

Noncontrolling Interests

As of June 30, 2020, the Company had two types of noncontrolling interests with respect to its consolidated subsidiaries, (1) noncontrolling interests related to the common unitholders of its Operating Partnership and (2) noncontrolling interests related to its consolidated real estate entities.  The noncontrolling interests relating to the limited partnership interests in the Operating Partnership are owned by the holders of the Class A OP Units. MAA is the sole general partner of the Operating Partnership and holds all of the outstanding Class B OP Units. Net income (after allocations to preferred ownership interests) is allocated to MAA and the noncontrolling interests based on their respective ownership percentages of the Operating Partnership. Issuance of additional Class A OP Units or Class B OP Units changes the ownership percentage of both the noncontrolling interests and MAA. The issuance of Class B OP Units generally occurs when MAA issues common stock and the issuance proceeds are contributed to the Operating Partnership in exchange for Class B OP Units equal to the number of shares of MAA’s common stock issued. At each reporting period, the allocation between total MAA shareholders’ equity and noncontrolling interests is adjusted to account for the change in the respective percentage ownership of the underlying equity of the Operating Partnership. MAA’s Board of Directors established economic rights in respect to each Class A OP Unit that were equivalent to the economic rights in respect to each share of MAA common stock. See Note 9 for additional details.

The noncontrolling interests relating to the Company’s two consolidated real estate entities are owned by private real estate companies that are generally responsible for the development and construction of the apartment communities that are owned through the consolidated real estate entities with a noncontrolling interest.  The entities were determined to be VIE’s with the Company designated as the primary beneficiary.  As a result, the accounts of the entities are consolidated by the Company.  As of June 30, 2020, the consolidated assets and liabilities of the Company’s consolidated real estate entities with a noncontrolling interest were $77.2 million and $8.4 million, respectively.  As of December 31, 2019, the consolidated assets and liabilities of the Company’s consolidated real estate entities with a noncontrolling interest were $46.0 million and $3.2 million, respectively.

Investments in Unconsolidated Affiliates

Investments in Unconsolidated Affiliates

The Company uses the equity method to account for its investments in a real estate joint venture and two technology-focused limited partnerships that qualify as a VIE. Management determined the Company is not the primary beneficiary in any of these investments but does have the ability to exert significant influence over the operations and financial policies of the real estate joint venture and considers its investment in the limited partnerships to be more than minor. The Company’s investment in the real estate joint venture was $43.6 million and $43.7 million as of June 30, 2020 and December 31, 2019, respectively.

As of June 30, 2020 and December 31, 2019, the Company’s investments in the technology-focused limited partnerships were $19.7 million and $13.1 million, respectively, and are included in “Other assets” in the accompanying Condensed Consolidated Balance Sheets. As of June 30, 2020, the Company was committed until February 2025 to make additional capital contributions totaling $23.0 million if and when called by the general partners of the limited partnerships.

Fair value Measurements

Fair Value Measurements

The Company applies the guidance in Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, to the valuation of real estate assets recorded at fair value, to its impairment valuation analysis of real estate assets, to its disclosure of the fair value of financial instruments, principally indebtedness and to its derivative financial instruments.  Fair value disclosures required under ASC Topic 820 as well as the Company’s derivative accounting policies are summarized in Note 7 utilizing the following hierarchy:

Level 1 - Quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date.

Level 2 - Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly.

Level 3 - Unobservable inputs for the assets or liability.

Revenue Recognition

Revenue Recognition

The Company primarily leases multifamily residential apartments to residents under operating leases generally due on a monthly basis with terms of approximately one year or less.  Rental revenues are recognized in accordance with ASC Topic 842, Leases, using a method that represents a straight-line basis over the term of the lease. In addition, in circumstances where a lease incentive is provided to tenants, the incentive is recognized as a reduction of rental revenues on a straight-line basis over the reasonably assured lease term.  Rental revenues represent approximately 93% of the Company’s total revenues and include gross rents charged less adjustments for concessions and bad debt.  Approximately 6% of the Company’s total revenues represent non-lease reimbursable property revenues from its residents for utility reimbursements, which are generally recognized and due on a monthly basis as residents obtain control of the service over the term of the lease.  The remaining 1% of the Company’s total revenues represents other non-lease property revenues primarily driven by nonrefundable fees and commissions.

In accordance with ASC Topic 842, rental revenues and non-lease reimbursable property revenues meet the criteria to be aggregated into a single lease component and are reported on a combined basis in the line item “Rental revenues”, as presented in the disaggregation of the Company’s revenues in Note 11.  Other non-lease property revenues are accounted for in accordance with ASC Topic 606, Revenue from Contracts with Customers, which requires revenue recognized outside of the scope of ASC Topic 842 to be recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. Other non-lease property revenues are reported in the line item “Other property revenues”, as presented in the disaggregation of the Company’s revenues in Note 11.

Leases

Leases

The Company is the lessee under certain ground, office, equipment and other operational leases, all of which are accounted for as operating leases in accordance with ASC Topic 842. The Company recognizes a right-of-use asset for the right to use the underlying asset for all leases where the Company is the lessee with terms of more than twelve months, and a related lease liability for the obligation to make lease payments. Expenses related to leases determined to be operating leases are recognized on a straight-line basis.  As of June 30, 2020 and December 31, 2019, right-of-use assets recorded within “Other assets” totaled $50.6 million and $53.8 million, respectively, and related lease obligations recorded within “Accrued expenses and other liabilities” totaled $32.5 million and $33.1 million, respectively, in the Condensed Consolidated Balance Sheets.  As of June 30, 2020, the Company’s operating leases had a weighted average remaining lease term of approximately 31 years and a weighted average discount rate of approximately 4.4%. Lease expense recognized for the three and six months ended June 30, 2020 and 2019 was immaterial to the Company. Cash paid for amounts included in the measurement of operating lease liabilities during the six months ended June 30, 2020 and 2019 was also immaterial.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Measurement of Credit Losses on Financial Instruments, which amends the current approach to estimate credit losses on certain financial assets, including trade and other receivables, available-for-sale securities and other financial instruments.  The ASU requires entities to estimate a lifetime expected credit loss for most financial instruments, including trade receivables.  Subsequent changes in the valuation allowance are recorded in current earnings and reversal of previous losses is permitted.  In November 2018, the FASB issued an amendment excluding operating lease receivables accounted for under ASC Topic 842 from the scope of the new credit losses standard. The Company adopted the standard on January 1, 2020. The adoption of ASU No. 2016-13 did not result in significant changes in the accounting for the Company’s approach to estimate credit losses on financial assets, as substantially all of the Company’s financial assets are operating lease receivables.
