Consolidation And Basis Of Presentation And Significant Accounting Policies [Abstract] |
Organization and Summary of Significant Accounting Policies | 1. Organization and Summary of 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, “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 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 March 31, 2025, MAA owned 116,916,381 OP Units (or 97.4% 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 from time to time. 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 interests, treasury shares, accumulated other comprehensive income or loss 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 interests, accumulated other comprehensive income or loss 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 U.S. As of March 31, 2025, the Company owned and operated 291 apartment communities (which does not include development communities under construction) 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 March 31, 2025, the Company also had seven development communities under construction, totaling 2,312 apartment units once complete, and development costs of $546.5 million had been incurred through March 31, 2025. The Company expects to complete two of these developments in 2025, four in 2026 and one in 2027. As of March 31, 2025, 35 of the Company’s apartment communities included retail components. The Company’s apartment communities, including development communities under construction, were located across 16 states and the District of Columbia as of March 31, 2025. Basis of Presentation and Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared by the Company’s management in accordance with U.S. 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. 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 that 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. 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. MAALP is classified as a VIE because the limited partners lack substantive kick-out rights and substantive participating rights, and the Company has concluded it is the primary beneficiary of MAALP. 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 significant influence or control include ownership of voting interests and participatory rights of investors (see “Investments in Unconsolidated Affiliates” below). Noncontrolling Interests As of March 31, 2025, 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 consolidated real estate entities are owned by private real estate companies that are generally responsible for the development, construction and lease-up 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 March 31, 2025, the consolidated assets of the Company’s consolidated real estate entities with a noncontrolling interest were $463.8 million, and consolidated liabilities were $20.8 million, net of eliminations. As of December 31, 2024, the consolidated assets of the Company’s consolidated real estate entities with a noncontrolling interest were $432.2 million, and consolidated liabilities were $27.1 million, net of eliminations. Investments in Unconsolidated Affiliates The Company uses the equity method to account for its investments in a real estate joint venture, as well as six technology-focused limited partnerships that each 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 investments in the limited partnerships to be more than minor. The Company’s investment in the real estate joint venture was $41.8 million and $41.7 million as of March 31, 2025 and December 31, 2024, respectively, and is included in “Investment in real estate joint venture” in the accompanying Condensed Consolidated Balance Sheets. The Company accounts for its investments in the technology-focused limited partnerships on a three month lag due to the timing the limited partnerships’ financial information is made available to the Company. As of March 31, 2025 and December 31, 2024, the Company’s investments in the limited partnerships were $67.6 million and $62.2 million, respectively, and are included in “Other assets” in the accompanying Condensed Consolidated Balance Sheets with any related earnings, including unrealized gains and losses on the underlying investments of the limited partnerships which are recorded at the estimated fair value, recognized in “Other non-operating income” in the accompanying Condensed Consolidated Statements of Operations. During the three months ended March 31, 2025 and 2024, the Company recognized $1.7 million and $8.1 million of income, respectively, from its investments in the limited partnerships. As of March 31, 2025, the Company was committed to make additional capital contributions totaling $26.9 million if and when called by the general partners of the limited partnerships. Marketable Equity Securities The Company’s investment in marketable equity securities is measured at fair value based on the quoted share price of the securities and is included in “Other assets” in the accompanying Condensed Consolidated Balance Sheets, with any related gains and losses, including realized and unrealized gains and losses, recognized in “Other non-operating income” in the accompanying Condensed Consolidated Statements of Operations. As of March 31, 2025 and December 31, 2024, the Company’s investment in the marketable equity securities was $2.3 million and $3.3 million, respectively. During the three months ended March 31, 2025 and 2024, the Company recognized $1.0 million and $3.0 million of expense, respectively, from its investment in marketable equity securities. 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 Accounting Standards Codification (“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 residents, 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 94% of the Company’s total revenues and include gross rents charged less adjustments for concessions and bad debt. Approximately 5% of the Company’s total revenues represent 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, which are recognized when earned. In accordance with ASC Topic 842, rental revenues and 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 12 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 March 31, 2025 and December 31, 2024, right-of-use assets recorded within “Other assets” totaled $39.9 million and $40.5 million, respectively, and related lease liabilities recorded within “Accrued expenses and other liabilities” totaled $25.7 million and $26.1 million, respectively, in the Condensed Consolidated Balance Sheets. Lease expense recognized for the three months ended March 31, 2025 and 2024 was immaterial to the Company. Cash paid for amounts included in the measurement of operating lease liabilities during the three months ended March 31, 2025 and 2024 was also immaterial. See Note 10 for additional disclosures regarding leases. Fair Value Measurements The Company applies the guidance in ASC Topic 820, Fair Value Measurements and Disclosures, to the valuation of acquired real estate assets recorded at fair value, to its impairment valuation analysis of real estate assets and to its valuation and disclosure of the fair value of financial instruments, which primarily consists of marketable equity securities, indebtedness and derivative instruments. Fair value disclosures required under ASC Topic 820 for the Company’s financial instruments 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. Certain long-lived assets are recorded at fair value when they are acquired or initially consolidated. The inputs associated with the valuation of long-lived assets are generally included in Level 2 of the fair value hierarchy.
