Explanatory Note

This report combines the Annual Reports on Form 10-K for the year ended December 31, 2017 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 96.4% owned subsidiary, Mid-America Apartments, L.P., are both required to file annual reports under the Securities Exchange Act of 1934, as amended.

Unless the context otherwise requires, all references in this Annual Report on Form 10-K 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" means 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 December 31, 2017, MAA owned 113,643,166 OP units (or approximately 96.4% of the total number of OP Units). MAA conducts substantially all of its business and holds substantially all of its assets 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 Annual Reports on Form 10-K of MAA and the Operating Partnership, including the notes to the 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 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 does not conduct business itself, other than 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 units of limited partnership interest.

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. Redeemable common units represent the number of outstanding limited partnership units as of the date of the applicable balance sheet, valued at the greater of the closing market price of MAA's common stock or the aggregate value of the individual partners' capital balances. Holders of OP Units (other than MAA and its entity affiliates) 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

1

date) or by delivering one share of MAA's common stock (subject to adjustment under specified circumstances) for each OP Unit so redeemed.     

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

• the selected financial data in Item 6 of this report;

• the consolidated financial statements in Item 8 of this report;

• certain accompanying notes to the consolidated financial statements, including Note 3 - Earnings per Common Share of MAA and Note 4 - Earnings per OP Unit of MAALP; Note 9 - Shareholders' Equity of MAA and Note 10 - Partners' Capital of MAALP; and Note 16 - Selected Quarterly Financial Information of MAA (Unaudited) and Note 17 - Selected Quarterly FinancialInformation of MAALP (Unaudited);

• the controls and procedures in Item 9A 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 the business is one enterprise, and we operate the business through the Operating Partnership.

ITEM 1. BUSINESS

Overview

MAA 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 and Southwest regions of the United States. As of December 31, 2017, activities include full ownership and operation of 301 multifamily properties, which includes commercial space at certain properties, four additional commercial properties, and a partial ownership in one multifamily property. These properties are located in Alabama, Arizona, Arkansas, Colorado, Florida, Georgia, Kansas, Kentucky, Maryland, Mississippi, Missouri, Nevada, North Carolina, South Carolina, Tennessee, Texas, Virginia and Washington, D.C. As of December 31, 2017, we maintained full or partial ownership in the following properties:

Multifamily:
	Consolidated Properties	Units	Unconsolidated Properties	Units	Total Properties	Total Units
	301	99,523	1	269	302	99,792
Commercial:
	Consolidated Properties	Sq. Ft. (1)	Unconsolidated Properties	Sq. Ft.	Total Properties	Total Sq. Ft.
	4	231,821	—	—	4	231,821

⁽¹⁾ Excludes commercial space located at our multifamily communities, which totals approximately 620,000 square feet of gross leasable space.

Our business is conducted principally through the Operating Partnership. MAA is the sole general partner of the Operating Partnership, holding 113,643,166 OP units, comprising a 96.4% partnership interest in the Operating Partnership as of December 31, 2017. MAA and MAALP were formed in Tennessee in 1993. As of December 31, 2017, we had 2,419 full time employees and 45 part-time employees.

Business Objectives

Our primary business objectives are to protect and grow existing property values, to maintain a stable and increasing cash flow that will fund our dividends and distributions through all parts of the real estate investment cycle, and to create shareholder value by growing in a disciplined manner. To achieve these objectives, we intend to continue to pursue the following goals and strategies:

• effectively and efficiently operate our existing properties with an intense property and asset management focus and a decentralized structure;

• manage real estate cycles by taking an opportunistic approach to buying, selling, developing and renovating apartment communities;

• diversify investment capital across markets in which we operate to achieve a balanced portfolio and minimize volatile operating performance; and

• actively manage our capital structure to enhance predictability of earnings to fund our dividends and distributions.

Operations

Our goal is to generate return on investment collectively and in each apartment community by increasing revenues, controlling operating expenses, maintaining high occupancy levels and reinvesting in the income producing capacity of each apartment community as appropriate. The steps taken to meet these objectives include:

• providing management information and improved customer services through technology innovations;

• utilizing systems to enhance property managers’ ability to optimize revenue by adjusting rental rates in response to local market conditions and individual unit amenities;

• implementing programs to control expenses through investment in cost-saving initiatives;

• analyzing individual asset productivity performances to identify best practices and improvement areas;

• maintaining the physical condition of each property through ongoing capital investments;

• improving the "curb appeal" of the apartment communities through extensive landscaping and exterior improvements, and repositioning apartment communities from time-to-time to enhance or maintain market positions;

• managing lease expirations to align with peak leasing traffic patterns and to maximize productivity of property staffing;

• allocating additional capital, including capital for selective interior and exterior improvements;

• compensating employees through performance-based compensation and stock ownership programs; and

• maintaining a hands-on management style and "flat" organizational structure that emphasizes property level decision making coupled with asset management and senior management's monitoring.

We believe that our decentralized operating structure capitalizes on specific market knowledge, provides greater personal accountability than a centralized structure and is beneficial in the acquisition and redevelopment processes. To support this decentralized operational structure, senior management, along with various asset management functions, are proactively involved in supporting and reviewing property management through extensive reporting processes and frequent on-site visits. To maximize the amount of information shared between senior management and the properties on a real-time basis, we utilize a web-based property management system. The system contains property and accounting modules that allow for operating efficiencies and continued expense control, provide for various expanded revenue management practices, and improve the support provided to on-site property operations. We use a "yield management" pricing program that helps our property managers optimize rental revenues, and we also utilize purchase order and accounts payable software to provide improved controls and management information.

Investment in technology continues to drive operating efficiencies in our business and help us to better meet the changing needs of our residents. Our residents have the ability to conduct business with us 24 hours a day, 7 days a week and complete online leasing applications and renewals via the use of our web-based resident Internet portal. Interacting with our residents through such technology has allowed us to improve resident satisfaction ratings and increase the efficiency of our operating teams.

We report in the following operating segments:

• Large market same store communities are generally communities in markets with a population of at least 1 million and at least 1% of the total public multifamily REIT units that we have owned and have been stabilized for at least a full 12 months.

4

• Secondary market same store communities are generally communities in markets with populations of more than 1 million but less than 1% of the total public multifamily REIT units or markets with populations of less than 1 million that we have owned and have been stabilized for at least a full 12 months.

• Non-same store communities and other includes recent acquisitions, communities in development or lease-up, communities that have been identified for disposition, and communities that have undergone a significant casualty loss. Also included in non-same store communities are non-multifamily activities.

On the first day of each calendar year, we determine the composition of our same store operating segments for that year as well as adjust the previous year, which allows us to evaluate full period-over-period operating comparisons. An apartment community in development or lease-up is added to the same store portfolio on the first day of the calendar year after it 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.

All properties acquired from Post Properties in the Merger remained in the Non-Same Store and Other operating segment during 2017, as the properties were recent acquisitions and had not been owned and stabilized for at least 12 months as of January 1, 2017. For additional information regarding our operating segments, see Note 14 to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

Acquisitions

One of our growth strategies is to acquire apartment communities that are located in various large or secondary markets primarily throughout the Southeast and Southwest regions of the United States. Acquisitions, along with dispositions, help us achieve and maintain our desired product mix, geographic diversification and asset allocation. Portfolio growth allows for maximizing the efficiency of the existing management and overhead structure. We have extensive experience in the acquisition of multifamily communities. We will continue to evaluate opportunities that arise, and we will utilize this strategy to increase our number of apartment communities in strong and growing markets.

We acquired the following apartment communities during the year ended December 31, 2017:

Community	Market	Units	Closing Date
Charlotte at Midtown	Nashville, TN	279	March 16, 2017
Acklen West End	Nashville, TN	320	December 28, 2017

Dispositions

We sell apartment communities and other assets that no longer meet our long-term strategy or when market conditions  are favorable, and we redeploy the proceeds from those sales to acquire, develop and redevelop additional apartment communities and rebalance our portfolio across or within geographic regions. Dispositions also allow us to realize a portion of the value created through our investments and provide additional liquidity. We are then able to redeploy the net proceeds from our dispositions in lieu of raising additional capital. In deciding to sell an apartment community, we consider current market conditions and generally solicit competing bids from unrelated parties for these individual assets, considering the sales price and other key terms of each proposal. We also consider portfolio dispositions when such a structure is useful to maximize proceeds and efficiency of execution. During the year ended December 31, 2017, we disposed of five multifamily properties totaling 1,760 units and four land parcels totaling approximately 23 acres.

Development

As another part of our growth strategy, we invest in a limited number of development projects. Development activities may be conducted through wholly-owned affiliated companies or through joint ventures with unaffiliated parties. Fixed price construction contracts are signed with unrelated parties to minimize construction risk. We typically manage the leasing portion of the project as units become available for lease. We may also engage in limited expansion development opportunities on existing communities in which we typically serve as the developer. While we seek opportunistic new development investments offering attractive long-term investment returns, we intend to maintain a total development commitment that we consider modest in relation to our total balance sheet and investment portfolio. During the year ended December 31, 2017, we incurred $170.1 million in development costs and completed 7 development projects.

5

The following multifamily projects were under development as of December 31, 2017 (dollars in thousands):

Project:	Market	Total Units	Units Completed	Cost to Date	Budgeted Cost	Estimated Cost Per Unit	Expected Completion
Post River North	Denver, CO	359	240	$81,195	$88,200	$246	1st Quarter 2018
1201 Midtown II	Charleston, SC	140	—	12,624	29,500	211	4th Quarter 2018
Post Centennial Park	Atlanta, GA	438	—	73,837	96,300	220	3rd Quarter 2018
		937	240	$167,656	$214,000

Redevelopment

We focus on both interior unit upgrades and exterior amenities above and beyond routine capital upkeep on existing apartment communities across our portfolio that we believe have the ability to support additional rent growth. During the year ended December 31, 2017, we renovated 8,375 units at an average cost of $5,463 per unit, achieving average rental rate increases of 8.8% above the normal market rate for similar but non-renovated units.

Capital Structure

We use a combination of debt and equity sources to fund our business objectives. We maintain a capital structure, focused on maintaining access, flexibility and low costs, that we believe allows us to proactively source potential investment opportunities in the marketplace. We structure our debt maturities to avoid disproportionate exposure in any given year. Our primary debt financing strategy is to access the unsecured debt markets to provide our debt capital needs, but we also maintain a limited amount of secured debt and maintain our access to both the secured and unsecured debt markets for maximum flexibility. We also believe that we have significant access to the equity capital markets.

At December 31, 2017, 27.5% of our total market capitalization consisted of debt borrowings, including 21.5% under unsecured credit facilities and unsecured senior notes and 6.0% under secured borrowings. We currently intend to target our total debt, net of cash held, to a range of approximately 32% to 38% of the undepreciated book value of our assets. Our charter and bylaws do not limit our debt levels and our Board of Directors can modify this policy at any time. We may issue new equity to maintain our debt within the target range. Covenants for our unsecured senior notes limit our debt to undepreciated book value of our assets to 60%. As of December 31, 2017, our ratio of total debt to our adjusted total assets (as defined in the covenants for the bonds issued by MAALP) was approximately 33.2%. We continuously review opportunities for lowering our cost of capital. We plan to continue using unsecured debt in order to take advantage of the lower cost of capital and flexibility provided by these markets. We will evaluate opportunities to repurchase shares when we believe that our share price is significantly below our net present value. We also look for opportunities where we can acquire or develop apartment communities, selectively funded or partially funded by sales of equity securities, when appropriate opportunities arise. We focus on improving the net present value of our investments by generating cash flows from our portfolio of assets above the estimated total cost of debt and equity capital. We routinely make new investments when we believe it will be accretive to shareholder value over the life of the investments.

Competition

All of our apartment communities are located in areas that include other apartment communities. Occupancy and rental rates are affected by the number of competitive apartment communities in a particular area. The owners of competing apartment communities may have greater resources than us, and the managers of these apartment communities may have more experience than our management. Moreover, single-family rental housing, manufactured housing, condominiums and the new and existing home markets provide housing alternatives to potential residents of apartment communities. Competition for new residents is generally intense across all of our markets. Some competing communities offer features that our communities do not have. Competing communities can use concessions or lower rents to obtain temporary competitive advantages. Also, some competing communities are larger or newer than our communities. The competitive position of each community is different depending upon many factors including sub-market supply and demand. In addition, other real estate investors compete with us to acquire existing properties and to develop new properties. These competitors include insurance companies, pension and investment funds, public and private real estate companies, investment companies and other public and private apartment

REITs, some of which may have greater resources, or lower capital costs, than we do.

6

We believe, however, that we are generally well-positioned to compete effectively for residents and investments. We believe our competitive advantages include:

• a fully integrated organization with property management, development, redevelopment, acquisition, marketing, sales and financing expertise;

• scalable operating and support systems, which include automated systems to meet the changing technological needs of our residents;

• access to a wide variety of debt and equity capital sources;

• geographic diversification with a presence in approximately 37 defined Metropolitan Statistical Areas, or MSAs, across the Southeast and Southwest regions of the United States; and

• significant presence in many of our major markets that allows us to be a local operating expert.

Moving forward, we plan to continue to optimize lease expiration management, improve expense control, increase resident retention efforts and align employee incentive plans with our performance. We believe this plan of operation, coupled with the portfolio’s strengths in targeting residents across a geographically diverse platform, should position us for continued operational upside. We also make capital improvements to both our apartment communities and individual units on a regular basis in order to maintain a competitive position in each individual market.

Environmental Matters

As a part of our standard apartment community acquisition and development processes, we generally obtain environmental studies of the sites from outside environmental engineering firms. The purpose of these studies is to identify potential sources of contamination at the site and to assess the status of environmental regulatory compliance. These studies generally include historical reviews of the site, reviews of certain public records, preliminary investigations of the site and surrounding properties, inspection for the presence of asbestos, poly-chlorinated biphenyls, or PCBs, and underground storage tanks and the preparation and issuance of written reports. Depending on the results of these studies, more invasive procedures, such as soil sampling or ground water analysis, may be performed to investigate potential sources of contamination. These studies must be satisfactorily completed before we take ownership of an acquisition or development property; however, no assurance can be given that the studies or additional documents reviewed identify all significant environmental risks. See "Risk Factors - Risks Relating to Our Real Estate Investments and Our Operations - Environmental problems are possible and can be costly."

The environmental studies we received on properties that we have acquired have not revealed any material environmental liabilities. Should any potential environmental risks or conditions be discovered during our due diligence process, the potential costs of remediation will be assessed carefully and factored into the cost of acquisition, assuming the identified risks and factors are deemed to be manageable and within reason. We are not aware of any existing conditions that we believe would be considered a material environmental liability. Nevertheless, it is possible that the studies do not reveal all environmental risks or that there are material environmental liabilities of which we are not aware. Moreover, no assurance can be given concerning future laws, ordinances or regulations, or the potential introduction of hazardous or toxic substances by neighboring properties or residents.

Merger of MAA and Post Properties

On December 1, 2016, MAA completed its merger with Post Properties. Pursuant to the Agreement and Plan of Merger, or the Merger Agreement, Post Properties merged with and into MAA, with MAA continuing as the surviving corporation, or the Parent Merger, and Post LP merged with and into MAALP, with MAALP continuing as the surviving entity, or the Partnership Merger. We refer to the Parent Merger, together with the Partnership Merger, as the Merger in this Annual Report on Form 10-K. The consolidated net assets and results of operations of Post Properties are included in our consolidated financial statements from and after the closing date of the Merger. The 2016 and 2017 operating results of the Post Properties assets we acquired in the Merger are included in our non-same store and other operating segment, as those assets were not eligible to be included in our same store segments until January 1, 2018.

Qualification as a Real Estate Investment Trust

MAA has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, or the Code. To continue to qualify as a REIT, MAA must continue to meet certain tests which, among other things, generally require that our assets consist primarily of real estate assets, our income be derived primarily from real estate assets, and that we distribute at least 90% of our REIT taxable income (other than our net capital gains) to our shareholders annually. If MAA maintains its qualification as a REIT, MAA generally will not be subject to U.S. federal income taxes at the corporate level on its net income

7

to the extent it distributes such net income to its shareholders annually. Even if MAA continues to qualify as a REIT, it will continue to be subject to certain federal, state and local taxes on its income and its property. In 2017, MAA paid total distributions of $3.48 per share of common stock to its shareholders, which was above the 90% REIT distribution requirement and was in excess of REIT taxable income.

Recent Developments

On February 1, 2018, the Company retired a $38.5 million mortgage associated with Highlands of West Village. The mortgage was scheduled to mature in May 2018.

ITEM 1A. RISK FACTORS

In addition to the other information contained in this Annual Report on Form 10-K, we have identified the following additional risks and uncertainties that may have a material adverse effect on our business prospects, financial condition or results of operations. Investors should carefully consider the risks described below before making an investment decision. Our business faces significant risks and the risks described below may not be the only risks we face. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impact our business operations. If any of these risks occur, our business prospects, financial condition or results of operations could suffer, the market price of our capital stock and the trading price of our debt securities could decline and you could lose all or part of your investment in our capital stock or debt securities.

RISKS RELATED TO OUR REAL ESTATE INVESTMENTS AND OUR OPERATIONS

Developments such as an economic downturn, instability in the banking sector or a negative impact on economic growth resulting from current or future legislation or government initiatives may materially and adversely affect our financial condition and results of operations.

The industry in which we operate may be adversely affected by national and international economic conditions. Although the U.S. real estate market has recently improved, certain international markets are experiencing increased levels of volatility due to a combination of factors, including, among others, political instability from ongoing geopolitical conflicts, high unemployment rates, fluctuating oil and gas prices and fiscal deficits, and these factors could contribute to an economic downturn in the U.S. If the U.S. experiences a downturn in the economy, instability in the banking sector or a negative impact on economic growth resulting from changes in legislation, government tax increases, debt policy or spending restrictions, we may experience adverse effects on our occupancy levels, our rental revenues and the value of our properties, any of which could adversely affect our cash flow, financial condition and results of operations.

Other economic risks which may adversely affect conditions in the markets in which we operate include the following:

• local conditions, such as an oversupply of apartments or other housing available for rent, or a reduction in demand for apartments in the area;

• low mortgage interest rates and home pricing, making alternative housing more affordable;

• government or builder incentives with respect to home ownership, making alternative housing options more attractive; and

• regional economic downturns which affect one or more of our geographical markets.

Failure to generate sufficient cash flows could limit our ability to make payments on our debt and to make distributions.

Our ability to make payments on our debt and to make distributions depends on our ability to generate cash flow in excess of operating costs and capital expenditure requirements and/or to have access to the markets for debt and equity

8

financing. Our funds from operations may be insufficient because of factors that are beyond our control. Such events or conditions could include:

• competition from other apartment communities;

• overbuilding of new apartments or oversupply of available apartments in our markets, which might adversely affect occupancy or rental rates and/or require rent concessions in order to lease apartments;

• conversion of condominiums and single family houses to rental use or the increase in the number condominiums and single family homes available for sale;

• weakness in the overall economy which lowers job growth and the associated demand for apartment housing;

• increases in operating costs (including real estate taxes, utilities and insurance premiums) due to inflation and other factors, which may not be offset by increased rental rates;

• inability to initially, or subsequently after lease terminations, rent apartments on favorable economic terms;

• failure of development communities to be completed within budget and on a timely basis or to lease-up as anticipated, if at all;

• changes in governmental regulations and the related costs of compliance;

• changes in laws including, but not limited to, tax laws and housing laws including the enactment of rent control laws or other laws regulating multifamily housing;

• withdrawal of government support of apartment financing through its financial backing of the Federal National Mortgage Association, or Fannie Mae, or the Federal Home Loan Mortgage Corporation, or Freddie Mac;

• an uninsured loss, including those resulting from a catastrophic storm, earthquake, or act of terrorism;

• changes in interest rate levels and the availability of financing, borrower credit standards, and down-payment requirements which could lead renters to purchase homes (if interest rates decrease and home loans are more readily available) or increase our acquisition and operating costs (if interest rates increase and financing is less readily available); and

• the relative illiquidity of real estate investments.

At times, we have relied on external funding sources to fully fund the payment of distributions to shareholders and our capital investment program, including our existing property developments. While we have sufficient liquidity to permit distributions at current rates through additional borrowings, if necessary, any significant and sustained deterioration in operations could result in our financial resources being insufficient to make payments on our debt and to make distributions at the current rate, in which event we would be required to reduce the distribution rate. Any decline in our funds from operations could adversely affect our ability to make distributions or to meet our loan covenants and could have a material adverse effect on our stock price or the trading price of our debt securities.

We are dependent on a concentration of our investments in a single asset class, making our results of operations more vulnerable to a downturn or slowdown in the sector or other economic factors.

As of December 31, 2017, substantially all of our investments are concentrated in the multifamily sector. As a result, we will be subject to risks inherent in investments in a single type of property. A downturn or slowdown in the demand for multifamily housing may have more pronounced effects on our results of operations or on the value of our assets than if we had diversified our investments into more than one asset class.

Our operations are concentrated in the Southeast and Southwest regions of the United States; we are subject to general economic conditions in the regions in which we operate.

As of December 31, 2017, approximately 39.4% of our portfolio is located in our top five markets: Atlanta, Georgia; Dallas, Texas; Austin, Texas; Charlotte, North Carolina; and Orlando, Florida. In addition, our overall operations are concentrated in the Southeast and Southwest regions of the United States. Our performance could be adversely affected by economic conditions in, and other factors relating to, these geographic areas, including supply and demand for apartments in these areas, zoning and other regulatory conditions and competition from other communities and alternative forms of housing. In particular our performance is disproportionately influenced by job growth and unemployment. To the extent the economic conditions, job growth and unemployment in any of these markets deteriorate or any of these areas experiences natural disasters, the value of our portfolio, our results of operations and our ability to make payments on our debt and to make distributions could be adversely affected.

Failure to succeed in new markets or sectors may have adverse consequences on our performance.

We may make acquisitions outside of our existing market areas if appropriate opportunities arise. Our historical experience in our existing markets does not ensure that we will be able to operate successfully in new markets, should we

9

choose to enter them. We may be exposed to a variety of risks if we choose to enter new markets, including an inability to accurately evaluate local market conditions, to identify appropriate acquisition opportunities, to hire and retain key personnel, and a lack of familiarity with local governmental and permitting procedures. In addition, we may abandon opportunities to enter new markets that we have begun to explore for any reason and may, as a result, fail to recover expenses already incurred.

Substantial competition among apartment communities and real estate companies may adversely affect our revenues and development and acquisition opportunities.

There are numerous other apartment communities and real estate companies, some of which may have greater financial and other resources than we have, within the market area of each of our communities that compete with us for residents and development and acquisition opportunities. The number of competitive apartment communities and real estate companies in these areas could have a material effect on (1) our ability to rent our apartments and generate revenues, and (2) development and acquisition opportunities. The activities of these competitors could cause us to pay a higher price for a new property than we otherwise would have paid or may prevent us from purchasing a desired property at all, which could have a material adverse effect on us and our ability to make payments on our debt and make distributions.

Actual or threatened terrorist attacks may have an adverse effect on our business and operating results and could decrease the value of our assets.

Actual or threatened terrorist attacks and other acts of violence or war could have a material adverse effect on our business and operating results. Attacks that directly impact one or more of our apartment communities could significantly affect our ability to operate those communities and thereby impair our ability to achieve our expected results. Further, our insurance coverage may not cover all losses caused by a terrorist attack. In addition, the adverse effects that such violent acts and threats of future attacks could have on the U.S. economy could similarly have a material adverse effect on our business and results of operations.

We rely on information technology systems in our operations, and any breach or security failure of those systems could materially adversely affect our business, results of operations, financial condition and reputation.

We rely on information technology systems to process, transmit and store information and to manage or support our business processes. We maintain confidential financial and business information regarding us and persons with which we do business on our information technology systems. We also collect and hold personally identifiable information of our residents and prospective residents in connection with our leasing and property management activities, and we collect and hold personally identifiable information of our employees in connection with their employment. In addition, we engage third party service providers that may collect and hold personally identifiable information of our residents, prospective residents and employees in connection with providing business services to us, including web hosting, property management, leasing, accounting and payroll services. The protection of the information technology systems on which we rely is critically important to us. We take steps, and generally require third party service providers to take steps, to protect the security of the information maintained in our and our service providers' information technology systems, including the use of systems, software, tools and monitoring to provide security for processing, transmitting and storing of the information. However, we face risks associated with breaches or security failures of the information technology systems on which we rely, which could result from, among other incidents, cyber-attacks or cyber-intrusions over the Internet, malware, computer viruses or employee error or misconduct. This risk of a breach or security failure, particularly through cyber-attacks or cyber-intrusion, has generally increased due to the rise in new technologies and the increased sophistication and activities of the perpetrators of attempted attacks and intrusions.

The security measures put in place by us and our service providers cannot provide absolute security and there can be no assurance that we or our service providers will not suffer a data security incident in the future, that unauthorized parties will not gain access to sensitive information stored on our or our service providers' systems, that such access will not, whether temporarily or permanently, impact, interfere with or interrupt our operations, or that any such incident will be discovered in a timely manner. Even the most well protected information, networks, systems and facilities remain potentially vulnerable as the techniques used in such attempted security breaches evolve and generally are not recognized until launched against a target, and in some cases are designed to not be detected and, in fact, may not be detected. Accordingly, we and our providers may be unable to anticipate these techniques or to implement adequate security barriers or other preventative measures. Further, in the future, we may be required to expend additional resources to continue to enhance information security measures or to investigate and remediate any information security vulnerabilities.

A data security incident could compromise our or our service providers' information technology systems, and the information stored by us or our service providers, including personally identifiable information of residents, prospective

10

residents and employees, could be accessed, misused, publicly disclosed, corrupted, lost or stolen. Any failure to prevent a breach or a security failure of our or our service providers' information technology systems could interrupt our operations, damage our reputation and brand, damage our competitive position, make it difficult for us to attract and retain residents, subject us to liability claims or regulatory penalties and could materially and adversely affect our business, financial condition or results of operations.

We may not realize the anticipated benefits of past or future apartment community acquisitions, and the failure to integrate acquired apartment communities and new personnel successfully could create inefficiencies.

We have acquired in the past, and if presented with attractive opportunities we intend to acquire in the future, apartment communities that meet our investment criteria. Our acquisition activities and their success are subject to the following risks:

• we may be unable to obtain financing for acquisitions on favorable terms or at all;

• even if we are able to finance the acquisition, cash flow from the acquisition may be insufficient to meet our required principal and interest payments on the acquisition;

• even if we enter into an acquisition agreement for an apartment community, we may be unable to complete the acquisition after incurring certain acquisition-related costs;

• we may incur significant costs and divert management's attention in connection with the evaluation and negotiation of potential acquisitions, including potential acquisitions that we are subsequently unable to complete;

• when we acquire an apartment community, we may invest additional amounts in it with the intention of increasing profitability, and these additional investments may not produce the anticipated improvements in profitability;

• we may be unable to quickly and efficiently integrate acquired apartment communities and new personnel into our existing operations, and the failure to successfully integrate such apartment communities or personnel will result in inefficiencies that could adversely affect our expected return on our investments and our overall profitability; and

• we may acquire properties that are subject to liabilities or that have problems relating to environmental condition, state of title, physical condition or compliance with zoning laws, building codes or other legal requirements and in each case, our acquisition may be without any, or with only limited, recourse with respect to unknown liabilities or conditions and we may be obligated to pay substantial sums to settle or cure it, which could adversely affect our cash flow and operating results.

We are subject to certain risks associated with selling apartment communities, which could limit our operational and financial flexibility.

We periodically dispose of apartment communities that no longer meet our strategic objectives, but adverse market conditions may make it difficult to sell apartment communities like the ones we own. We cannot predict whether we will be able to sell any property for the price or on the terms we set, or whether any price or other terms offered by a prospective purchaser would be acceptable to us. We also cannot predict the length of time needed to find a willing purchaser and to close the sale of a property. Furthermore, we may be required to expend funds to correct defects or to make improvements before a property can be sold. These conditions may limit our ability to dispose of properties and to change our portfolio promptly in order to meet our strategic objectives, which may in turn have a material adverse effect on our financial condition and the market value of our securities. We are also subject to the following risks in connection with sales of our apartment communities:

• a significant portion of the proceeds from our overall property sales may be held by intermediaries in order for some sales to qualify as like-kind exchanges under Section 1031 of the Code, so that any related capital gain can be deferred for federal income tax purposes. As a result, we may not have immediate access to all of the cash proceeds generated from our property sales. In addition, if a transaction intended to qualify as a Section 1031 exchange is later determined to be taxable, we may face adverse consequences, and if the laws applicable to such transactions are amended or repealed, we may not be able to dispose of properties on a tax deferred basis. Intermediary agents of Section 1031 exchange transactions typically handle large sums of money in trusts. Misappropriation of funds by one of these agents could have a material negative impact on our results of operations. Additionally, misappropriation of funds could result in the disposal of the property not qualifying for a tax deferred basis and adversely affect our financial condition. It is also possible the qualification of a transaction as a Section 1031 exchange could be successfully challenged and determined to be currently taxable. In such case, our taxable income and earnings and profits would increase, which could increase the dividend income to our shareholders by reducing any return of capital they received. In some circumstances, we may be required to pay additional dividends or, in lieu of additional dividends, corporate income tax, possibly including interest and penalties. As a result, we may be required to borrow funds in order to pay additional dividends or taxes and the payment of such taxes could cause us to have less cash available to distribute to our shareholders. In addition, if a Section 1031 exchange were later to be determined to be taxable, we

11

may be required to amend our tax returns for the applicable year in question, including any information reports sent to our shareholders; and

• federal tax laws applicable to REITs limit our ability to profit on the sale of communities, and this limitation may prevent us from selling communities when market conditions are favorable.

Property ownership through joint ventures could limit our ability to act exclusively in our interest.

From time to time we may acquire and/or develop properties in joint ventures with other persons or entities when we believe circumstances warrant the use of such structures. In that case, we could become engaged in a dispute with one or more of our partners which might affect our ability to operate a jointly-owned property. Moreover, our partners could have business, economic or other objectives that are inconsistent with our objectives, including objectives that relate to the appropriate timing and terms of any sale or refinancing of a property. In some instances, our partners could have competing interests in our markets that could create conflicts of interest. Also, our partners might refuse to make capital contributions when due and we may be responsible to our partners for indemnifiable losses. In general, we and our partners could each have the right to trigger a buy-sell arrangement, which could cause us to sell our interest, or acquire our partners' interest, at a time when we otherwise would not have initiated such a transaction and may result in the valuation of our interest in the joint venture (if we are the seller) or of our partners' interest in the joint venture (if we are the buyer) at levels which may not be representative of the valuation that would result from an arm's length marketing process. Other potential risks of a jointly-owned property include (i) a deadlock if we and our partners are unable to agree upon certain major and other decisions, (ii) a limitation of our ability to liquidate our position in the partnership or joint venture without the consent of the other partners and (iii) a requirement to provide guarantees in favor of lenders with respect to the indebtedness of the joint venture.

Environmental problems are possible and can be costly.

Under various federal, state and local laws, ordinances and regulations, a current or previous owner or operator of real estate may be liable for the costs of removal or remediation of certain hazardous or toxic substances in, on, around or under such property. Such laws often impose such liability without regard to whether the owner or operator knew of, or was responsible for, the presence of such hazardous or toxic substances. The presence of, or failure to properly remediate, hazardous, toxic substances or petroleum product releases may adversely affect the owner's or operator’s ability to sell or rent the affected property or to borrow using the property as collateral. Persons who arrange for the disposal or treatment of hazardous or toxic substances may also be liable for the costs of removal or remediation of hazardous or toxic substances at a disposal or treatment facility, whether or not the facility is owned or operated by the person. Certain environmental laws impose liability for the release of asbestos-containing materials into the air, and third parties may also seek recovery from owners or operators of real property for personal injury associated with asbestos-containing materials and other hazardous or toxic substances. Federal and state laws also regulate the operation and subsequent removal of certain underground storage tanks. In connection with the current or former ownership (direct or indirect), operation, management, development or control of real property, we may be considered an owner or operator of such communities or as having arranged for the disposal or treatment of hazardous or toxic substances and, therefore, may be potentially liable for removal or remediation costs, as well as certain other costs, including governmental fines, and claims for injuries to persons and property.

Our current policy is to obtain a Phase I environmental study on each apartment community that we seek to acquire or develop, which generally does not involve invasive techniques such as soil or ground water sampling, and to proceed accordingly. We cannot assure you, however, that the Phase I environmental studies or other environmental studies undertaken with respect to any of our current or future apartment communities will reveal:

• all or the full extent of potential environmental liabilities;

• that any prior owner or operator of a property did not create any material environmental condition unknown to us;

• that a material environmental condition does not otherwise exist as to any one or more of such apartment communities; or

• that environmental matters will not have a material adverse effect on us and our ability to make distributions and pay amounts due on our debt.

Certain environmental laws impose liability on a previous owner of property to the extent that hazardous or toxic substances were present during the prior ownership period. A transfer of the property does not relieve an owner of such liability. Thus, we may have liability with respect to apartment communities previously sold by our predecessors or by us. There have been a number of lawsuits against owners and operators of multifamily communities alleging personal injury and property damage caused by the presence of mold in residential real estate. Some of these lawsuits have resulted in substantial monetary judgments or settlements. Insurance carriers have reacted to these liability awards by excluding mold-related claims from

12

standard policies and pricing mold endorsements separately. We have obtained a separate pollution insurance policy that covers mold-related claims and have adopted programs designed to minimize the existence of mold in any of our communities as well as guidelines for promptly addressing and resolving reports of mold. To the extent not covered by our pollution policy, the presence of mold could expose us to liability from residents and others if property damage or health concerns, or allegations thereof, arise.

Extreme weather or natural disasters may cause property damage or disrupt business, which could harm our business and operating results.

We have properties located in areas that may be subject to extreme weather and natural disasters, including, but not limited to, earthquakes, winds, floods, hurricanes and fires. Such conditions may damage our properties, disrupt our operations and adversely impact our tenants. There can be no assurances that such conditions will not have a material adverse effect on our properties, operations or business.

Losses from catastrophes may exceed our insurance coverage, which may negatively impact our results of operations and reduce the value of our properties.

We carry comprehensive liability and property insurance on our communities and intend to obtain similar coverage for apartment communities we acquire in the future. Some losses, generally of a catastrophic nature, such as losses from floods, hurricanes or earthquakes, are subject to limitations, and thus may be uninsured. We exercise our discretion in determining amounts, coverage limits and deductibility provisions of insurance, with a view to maintaining appropriate insurance on our investments at a reasonable cost and on suitable terms. If we suffer a substantial loss, our insurance coverage may not be sufficient to pay the full current market value or current replacement value of our lost investment. Inflation, changes in building codes and ordinances, environmental considerations and other factors also might make it infeasible to use insurance proceeds to replace a property after it has been damaged or destroyed. Any losses we experience that are not fully covered by our insurance may negatively impact our results of operations and may reduce the value of our properties.

Increasing real estate taxes, utilities and insurance premiums may negatively impact operating results.

As a result of our substantial real estate holdings, the cost of real estate taxes, utilities and insuring our apartment communities is a significant component of expense. Real estate taxes, utilities and insurance premiums are subject to significant increases and fluctuations, which can be widely outside of our control. If the costs associated with real estate taxes, utilities and insurance premiums should rise, without being offset by a corresponding increase in revenues, our results of operations could be negatively impacted, and our ability to make payments on our debt and to make distributions could be adversely affected.

Compliance or failure to comply with laws requiring access to our properties by disabled persons could result in substantial cost.

The Americans with Disabilities Act of 1990, or the ADA, the Fair Housing Act of 1988, or the FHA, and other federal, state and local laws generally require that public accommodations be made accessible to disabled persons. Noncompliance could result in the imposition of fines by the government or the award of damages to private litigants. These laws may require us to modify our existing apartment communities. These laws may also restrict renovations by requiring improved access to such buildings by disabled persons or may require us to add other structural features that increase our construction costs. Legislation or regulations adopted in the future may impose further burdens or restrictions on us with respect to improved access by disabled persons. We cannot ascertain the costs of compliance with these laws, which may be substantial.

Development and construction risks could impact our profitability.

As of December 31, 2017, we had three development communities under construction totaling 937 units. We may make further investments in these and other development communities as opportunities arise and may do so through joint ventures with unaffiliated parties. Our development and construction activities are subject to the following risks:

• we may be unable to obtain, or face delays in obtaining, necessary zoning, land-use, building, occupancy and other required governmental permits and authorizations, which could result in increased development costs, could delay initial occupancy dates for all or a portion of a development community, and could require us to abandon our activities entirely with respect to a project for which we are unable to obtain permits or authorizations;

• we may be unable to obtain financing for development activities under favorable terms, which could cause a delay in

13

construction resulting in increased costs, decreases in revenue, and potentially cause us to abandon the opportunity;

• yields may be less than anticipated as a result of delays in completing projects, costs that exceed budget, higher than expected concessions for lease-up and lower rents than initially estimated;

• bankruptcy of developers in our development projects could impose delays and costs on us with respect to the development of our communities and may adversely affect our financial condition and results of operations;

• we may abandon development opportunities that we have already begun to explore, and we may fail to recover expenses already incurred in connection with exploring such opportunities;

• we may be unable to complete construction and lease-up of an apartment community on schedule, or incur development or construction costs that exceed our original estimates, and we may be unable to charge rents that would compensate for any increase in such costs;

• occupancy rates and rents at a newly developed apartment community may fluctuate depending on a number of factors, including market and economic conditions, preventing us from meeting our profitability goals for that community;

• when we sell to third parties apartment communities or properties that we developed or renovated, we may be subject to warranty or construction defects that are uninsured or exceed the limit of our insurance; and

• our failure to successfully enter into a joint venture agreement may prohibit an otherwise advantageous investment if we cannot raise the money through other means.

Short-term leases expose us to the effects of declining market rents.

Our apartment leases are generally for a term of one year or less. As these leases typically permit the residents to leave at the end of the lease term without penalty, our revenues are impacted by declines in market rents more quickly than if our leases were for longer terms.

We may not realize the anticipated synergies and other benefits of the Merger or do so within the anticipated time frame.

Because Post Properties was a public company, we expect to benefit from the elimination of duplicative costs associated with supporting Post Properties' public company platform and the leveraging of our technology and systems. These savings are expected to be realized upon full integration. Integration efforts are ongoing, and we may encounter difficulties and delays in the integration process. If we are unable to manage and complete the integration of Post Properties' business in an efficient and timely manner, we may not achieve the cost savings anticipated to result from the Merger in the expected time frame, or at all. Likewise, there can be no assurance that we will realize other anticipated operating efficiencies and synergies from the Merger.

RISKS RELATED TO OUR INDEBTEDNESS AND FINANCING ACTIVITIES

Our substantial indebtedness could adversely affect our financial condition and results of operations.

As of December 31, 2017, the amount of our total debt was approximately $4.5 billion. We may incur additional indebtedness in the future in connection with, among other things, our acquisition, development and operating activities.

The degree of our leverage creates significant risks, including the following:

• we may be required to dedicate a substantial portion of our funds from operations to servicing our debt and our cash flow may be insufficient to make required payments of principal and interest;

• debt service obligations will reduce funds available for distribution and funds available for acquisitions, development and redevelopment;

• we may be more vulnerable to economic and industry downturns than our competitors that have less debt;

• we may be limited in our ability to respond to changing business and economic conditions;

• we may default on our indebtedness, which could result in acceleration of those obligations, assignment of rents and leases and loss of properties to foreclosure; and

• if one of our subsidiaries defaults, it could trigger a cross default or cross acceleration provision under other indebtedness, which could cause an immediate default or could allow the lenders to declare all funds borrowed thereunder to be due and payable.

If any one of these events were to occur, our financial condition and results of operations could be materially and adversely affected.

14

We may be unable to renew, repay or refinance our outstanding debt, which could negatively impact our financial condition and results of operations.

We are subject to the normal risks associated with debt financing, including the risk that our cash flow will be insufficient to meet required payments of principal and interest, the risk that either secured or unsecured indebtedness, will not be able to be renewed, repaid or refinanced when due or that the terms of any renewal or refinancing will not be as favorable as the existing terms of such indebtedness. If we are unable to refinance our indebtedness on acceptable terms, if at all, we might be forced to dispose of one or more of our apartment communities on disadvantageous terms, which might result in losses to us. Such losses could have a material adverse effect on us and our ability to make distributions and pay amounts due on our debt. Furthermore, if a property is mortgaged to secure payment of indebtedness and we are unable to meet mortgage payments, the mortgagee could foreclose upon the property, appoint a receiver and receive an assignment of rents and leases or pursue other remedies, all with a consequent loss of our revenues and asset value. Foreclosures could also create taxable income without accompanying cash proceeds, thereby hindering our ability to meet the REIT distribution requirements of the Code.

Rising interest rates would increase the cost of our variable rate debt and could adversely impact additional debt we may incur in the future.

We have incurred and expect in the future to incur indebtedness that bears interest at variable rates. Accordingly, increases in interest rates would increase our interest costs, which could have a material adverse effect on us and our ability to make distributions and pay amounts due on our debt or cause us to be in default under certain debt instruments. In addition, an increase in market interest rates may lead holders of shares of our common stock to demand a higher yield on their shares from distributions by us, which could adversely affect the market price for our common stock. In June 2017, the Federal Reserve reached a decision to raise the federal funds rate by 0.25 points with additional gradual increases anticipated to occur over the next year, subject to ongoing economic uncertainty. In December 2017, the Federal Reserve increased the federal funds rate by another 0.25 points to a range of 1.25 percent to 1.5 percent. These increases in the federal funds rate and any future increases due to other key economic indicators, such as the unemployment rate or inflation, may cause interest rates and borrowing costs to rise, which may negatively impact our ability to access the debt markets on favorable terms. Any continued adverse economic conditions could have a material adverse effect on our business, financial condition and results of operations.

We may incur additional debt in the future, which may adversely impact our financial condition.

We currently fund the acquisition and development of apartment communities partially through borrowings (including our revolving credit facility) as well as from other sources such as sales of communities which no longer meet our investment criteria. In addition, we may fund other of our capital requirements through debt. Our organizational documents do not contain any limitation on the amount of indebtedness that we may incur, and we may incur more debt in the future. Accordingly, subject to limitations on indebtedness set forth in various loan agreements and the indentures governing our senior notes, we could become more highly leveraged, resulting in an increase in debt service and an increased risk of default on our obligations, which could have a material adverse effect on our financial condition, our ability to access debt and equity capital markets in the future and our ability to make payments on our debt and to make distributions.

The restrictive terms of certain of our indebtedness may cause acceleration of debt payments.

At December 31, 2017, we had outstanding borrowings of approximately $4.5 billion. Our indebtedness contains financial covenants as to interest coverage ratios, maximum secured debt, maintenance of unencumbered asset value, and total debt to gross assets, among others, and cross default provisions with other material debt. In the event that an event of default occurs, our lenders may declare borrowings under the respective loan agreements to be due and payable immediately, which could have a material adverse effect on our financial condition and our ability to make payments on our debt and to make distributions.

Failure to hedge effectively against interest rates may adversely affect results of operations.

From time-to-time, we may seek to manage our exposure to interest rate volatility by using interest rate hedging arrangements, such as interest rate cap agreements and interest rate swap agreements. These agreements involve risks, such as the risk that the counterparties may fail to honor their obligations under these arrangements, that these arrangements may not be effective in reducing our exposure to interest rate changes and that a court could rule that such an agreement is not legally enforceable. Hedging may reduce overall returns on our investments. Failure to hedge effectively against interest rate changes could have a material adverse effect on us and our ability to make payments on our debt and to make distributions.

15

A downgrade in our credit ratings could have a material adverse effect on our business, financial condition and results of operations.

We have a significant amount of debt outstanding. We are currently assigned corporate credit ratings from each of the three ratings agencies based on their evaluation of our creditworthiness. These ratings are based on a number of factors, which include their assessment of our financial strength, liquidity, capital structure, asset quality, and sustainability of cash flows and earnings. If our credit ratings are downgraded or other negative action is taken, we could be required to pay additional interest and fees on our outstanding borrowings. In addition, a downgrade may adversely impact our ability to borrow secured and unsecured debt and otherwise limit our access to capital, which could adversely affect our business, financial condition and results of operations. 

Financing may not be available and could be dilutive.

Our capital requirements depend on numerous factors, including the occupancy and turnover rates of our apartment communities, development and capital expenditures, costs of operations and potential acquisitions. We cannot accurately predict the timing and amount of our capital requirements. If our capital requirements vary materially from our plans, we may require additional financing sooner than anticipated. We and other companies in the real estate industry have experienced limited availability of financing from time to time. Restricted lending practices could impact our ability to obtain debt financing. If we issue additional equity securities to obtain additional financing, the interest of our existing shareholders could be diluted.

RISKS RELATED TO MAA'S ORGANIZATION AND OWNERSHIP OF ITS STOCK

MAA's ownership limit restricts the transferability of its capital stock.

MAA's charter limits ownership of its capital stock by any single shareholder to 9.9% of the value of all outstanding shares of its capital stock, both common and preferred, unless approved by its Board of Directors. The charter also prohibits anyone from buying shares if the purchase would result in it losing REIT status. This could happen if a share transaction results in fewer than 100 persons owning all of its shares or in five or fewer persons, applying certain broad attribution rules of the Code, owning 50% or more of its shares. If an investor acquires shares in excess of the ownership limit or in violation of the ownership requirements of the Code for REITs, MAA:

• will consider the transfer to be null and void;

• will not reflect the transaction on its books;

• may institute legal action to enjoin the transaction;

• will not pay dividends or other distributions with respect to those shares;

• will not recognize any voting rights for those shares;

• will consider the shares held in trust for its benefit; and

• will either direct the holder to sell the shares and turn over any profit to MAA, or MAA will redeem the shares. If MAA redeems the shares, the holder will be paid a price equal to the lesser of:

◦ the principal price paid for the shares by the holder,

◦ a price per share equal to the market price (as determined in the manner set forth in its charter) of the applicable capital stock,

◦ the market price (as so determined) on the date such holder would, but for the restrictions on transfers set forth in its charter, be deemed to have acquired ownership of the shares and

◦ the maximum price allowed under the Tennessee Greenmail Act (such price being the average of the highest and lowest closing market price for the shares during the 30 trading days preceding the purchase of such shares or, if the holder of such shares has commenced a tender offer or has announced an intention to seek control of MAA, during the 30 trading days preceding the commencement of such tender offer or the making of such announcement).

The redemption price may be paid, at MAA's option, by delivering one common unit (subject to adjustment from time to time in the event of, among other things, stock splits, stock dividends, or recapitalizations affecting its common stock or certain mergers, consolidations or asset transfers by MAA) issued by the Operating Partnership for each excess share being redeemed.

If an investor acquires shares in violation of the limits on ownership described above:

• the holder may lose its power to dispose of the shares;

16

• the holder may not recognize profit from the sale of such shares if the market price of the shares increases; and

• the holder may be required to recognize a loss from the sale of such shares if the market price decreases.

Future offerings of debt or equity securities, which may rank senior to our common stock, may adversely affect the market price of our common stock.

If we decide to issue additional debt securities in the future, which would rank senior to our common stock, it is likely that they will be governed by an indenture or other instrument containing covenants restricting our operating flexibility. Additionally, any equity securities or convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of our common stock and may result in dilution to owners of our common stock. We and, indirectly, our shareholders, will bear the cost of issuing and servicing such securities. Because our decision to issue debt or equity securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of any future offerings. Thus, holders of our common stock will bear the risk of our future offerings reducing the market price of our common stock and diluting the value of their stock holdings.

The form, timing and amount of dividend distributions in future periods may vary and be impacted by economic and other considerations.

Though our Board of Directors has a history of declaring dividends in advance of the quarter they are paid, the form, timing and amount of dividend distributions will be declared, and standing practice changed, at the discretion of the Board of Directors. The form, timing and amount of dividend distributions will depend on actual cash from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Code and other factors as our Board of Directors may consider relevant. Our Board of Directors may modify our dividend policy from time to time.

Provisions of MAA's charter and Tennessee law may limit the ability of a third party to acquire control of MAA.

Ownership Limit

The 9.9% ownership limit discussed above may have the effect of precluding acquisition of control of MAA by a third party without the consent of our Board of Directors.

Preferred Stock

MAA's charter authorizes our Board of Directors to issue up to 20,000,000 shares of preferred stock, 867,846 of which have been designated as 8.50% Series I Cumulative Redeemable Preferred Stock, which we refer to as MAA Series I preferred stock. In addition to the MAA Series I preferred stock, the Board of Directors may establish the preferences and rights of any other series of preferred shares issued. The issuance of preferred stock could have the effect of delaying or preventing someone from taking control of MAA, even if a change in control were in MAA shareholders’ best interests. As of December 31, 2017, 867,846 shares of preferred stock were issued and outstanding, all of which shares were MAA Series I preferred stock.

Tennessee Anti-Takeover Statutes

As a Tennessee corporation, MAA is subject to various legislative acts, which impose restrictions on and require compliance with procedures designed to protect shareholders against unfair or coercive mergers and acquisitions. These statutes may delay or prevent offers to acquire MAA and increase the difficulty of consummating any such offers, even if MAA's acquisition would be in MAA shareholders’ best interests.

Market interest rates and low trading volume may have an adverse effect on the market value of MAA's common stock.

The market price of shares of common stock of a REIT may be affected by the distribution rate on those shares, as a

percentage of the price of the shares, relative to market interest rates. If market interest rates increase, prospective purchasers of MAA's common stock may expect a higher annual distribution rate. Higher interest rates would not, however, result in more funds for MAA to distribute and, in fact, would likely increase MAA's borrowing costs and potentially decrease funds available for distribution. This could cause the market price of MAA's common stock to go down. In addition, although MAA's common stock is listed on the NYSE, the daily trading volume of MAA's common stock may be lower than the trading volume for other industries. As a result, MAA's investors who desire to liquidate substantial holdings may find that they are unable to dispose of their shares in the market without causing a substantial decline in the market value of MAA's common stock.

17

Changes in market conditions or a failure to meet the market’s expectations with regard to our results of operations and cash distributions could adversely affect the market price of MAA's common stock.

We believe that the market value of a REIT’s equity securities is based primarily upon the market’s perception of the REIT’s growth potential and its current and potential future cash distributions, and is secondarily based upon the real estate market value of the underlying assets. For that reason, MAA's common stock may trade at prices that are higher or lower than the net asset value per share. To the extent we retain operating cash flow for investment purposes, working capital reserves or other purposes, these retained funds, while increasing the value of our underlying assets, may not correspondingly increase the market price of MAA's common stock. In addition, we are subject to the risk that our cash flow will be insufficient to pay distributions to MAA's shareholders. Our failure to meet the market’s expectations with regard to future earnings and cash distributions would likely adversely affect the market price of MAA's common stock. 

The stock markets, including the NYSE, on which MAA lists its common stock, have, at times, experienced significant price and volume fluctuations. As a result, the market price of MAA's common stock could be similarly volatile, and investors in MAA's common stock may experience a decrease in the value of their shares, including decreases unrelated to our operating performance or prospects. Among the market conditions that may affect the market price of MAA's publicly traded securities are the following:

• our financial condition and operating performance and the performance of other similar companies;

• actual or anticipated differences in our quarterly and annual operating results;

• changes in our revenues or earnings estimates or recommendations by securities analysts;

• publication of research reports about us or our industry by securities analysts;

• additions and departures of key personnel;

• inability to access the capital markets;

• strategic decisions by us or our competitors, such as acquisitions, dispositions, spin-offs, joint ventures, strategic investments or changes in business strategy;

• the issuance of additional shares of MAA's common stock, or the perception that such sales may occur, including under MAA's at-the-market offering programs;

• the reputation of REITs generally and the reputation of REITs with portfolios similar to ours;

• the attractiveness of the securities of REITs in comparison to securities issued by other entities (including securities issued by other real estate companies);

• an increase in market interest rates, which may lead prospective investors to demand a higher distribution rate in relation to the price paid for MAA's common stock;

• the passage of legislation or other regulatory developments that adversely affect us or our industry;

• speculation in the press or investment community;

• actions by institutional shareholders or hedge funds;

• changes in accounting principles;

• terrorist acts; and

• general market conditions, including factors unrelated to our performance.

In the past, securities class action litigation has often been instituted against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs and divert our management’s attention and resources.

RISKS RELATED TO THE OPERATING PARTNERSHIP'S ORGANIZATION AND OWNERSHIP OF OP UNITS

The Operating Partnership's existing unitholders have limited approval rights, which may prevent the Operating Partnership's sole general partner, MAA, from completing a change of control transaction that may be in the best interests of all unitholders and of all the shareholders of MAA.

MAA may not engage in a sale or other disposition of all or substantially all of the assets of the Operating Partnership, dissolve the Operating Partnership or, upon the occurrence of certain triggering events, take any action that would result in any unitholder realizing taxable gain, without the approval of the holders of a majority of the outstanding OP Units held by holders other than MAA or its affiliates, or Class A OP Units. The right of the holders of our Class A OP Units to vote on these transactions could limit MAA's ability to complete a change of control transaction that might otherwise be in the best interest of all unitholders of the Operating Partnership and all shareholders of MAA.

18

In certain circumstances, certain of the Operating Partnership's unitholders must approve the Operating Partnership's sale of certain properties contributed by the unitholders.

In certain circumstances as detailed in the partnership agreement of the Operating Partnership, the Operating Partnership may not sell or otherwise transfer certain properties unless a specified percentage of the limited partners who were partners in the limited partnership holding such properties at the time of its acquisition by us approves such sale or transfer. The exercise of these approval rights by the Operating Partnership's unitholders could delay or prevent the Operating Partnership from completing a transaction that may be in the best interest of all of the Operating Partnership's unitholders and all shareholders of MAA.

MAA, its officers and directors have substantial influence over the Operating Partnership's affairs.

MAA, as the Operating Partnership's sole general partner and acting through its officers and directors, has a substantial influence on the Operating Partnership's affairs. MAA, its officers and directors could exercise their influence in a manner that is not in the best interest of the Operating Partnership's unitholders. Also, MAA owns approximately 96.4% of the OP Units and as such, will have substantial influence on the outcome of substantially all matters submitted to the Operating Partnership's unitholders for approval.

Market interest rates and low trading volume may have an adverse effect on the market value of MAA's common stock, which would affect the redemption price of the OP Units.

The market price of shares of common stock of a REIT may be affected by the distribution rate on those shares, as a percentage of the price of the shares, relative to market interest rates. If market interest rates increase, prospective purchasers of MAA's common stock may expect a higher annual distribution rate. Higher interest rates would not, however, result in more funds for MAA to distribute and, in fact, would likely increase MAA's borrowing costs and potentially decrease funds available for distribution. This could cause the market price of MAA's common stock to go down, which would reduce the price received upon redemption of any OP Units, or if MAA so elects, the value of MAA's common stock received in lieu of cash upon redemption of such OP Units. In addition, although MAA's common stock is listed on the NYSE, the daily trading volume of MAA's shares may be lower than the trading volume for companies in other industries. As a result, MAA's investors who desire to liquidate substantial holdings may find that they are unable to dispose of their shares in the market without causing a substantial decline in the market value of the shares.

Insufficient cash flow from operations or a decline in the market price of MAA's common stock may reduce the amount of cash available to the Operating Partnership to meet its obligations.

The Operating Partnership is subject to the risk that its cash flow will be insufficient to service its debt and to pay distributions to its unitholders, which may cause MAA to not have the funds to pay distributions to its shareholders. MAA’s failure to meet the market’s expectations with regard to future results of operations and cash distributions would likely adversely affect the market price of its shares and thus potentially reduce MAA’s ability to contribute funds from issuances down to the Operating Partnership, resulting in a lower level of cash available for investment, to service debt or to make distributions to the Operating Partnership’s unitholders.

RISKS RELATED TO TAX LAWS

Failure to qualify as a REIT would cause us to be taxed as a corporation, which would significantly reduce funds available for distribution to shareholders.

If MAA fails to qualify as a REIT for federal income tax purposes, MAA will be subject to federal income tax on its taxable income at regular corporate rates (subject to any applicable alternative minimum tax) without the benefit of the dividends paid deduction applicable to REITs. In addition, unless MAA is entitled to relief under applicable statutory provisions, MAA would be ineligible to make an election for treatment as a REIT for the four taxable years following the year in which it loses its qualification. The additional tax liability resulting from the failure to qualify as a REIT would significantly reduce or eliminate the amount of funds available for distribution to MAA’s shareholders. MAA’s failure to qualify as a REIT also could impair its ability to expand its business and raise capital, and would adversely affect the value of

MAA’s stock.

MAA believes that it is organized and qualified as a REIT, and MAA intends to operate in a manner that will allow it to continue to qualify as a REIT. MAA cannot assure, however, that it is qualified or will remain qualified as a REIT. This is because qualification as a REIT involves the application of highly technical and complex provisions of the Code for which

19

there are only limited judicial and administrative interpretations and involves the determination of a variety of factual matters and circumstances not entirely within MAA’s control. In addition, future legislation, new regulations, administrative interpretations or court decisions may significantly change the tax laws or the application of the tax laws with respect to qualification as a REIT for federal income tax purposes or the federal income tax consequences of qualification as a REIT.

Even if MAA qualifies as a REIT, MAA will be subject to various federal, state and local taxes, including property taxes and income taxes on taxable income that MAA does not timely distribute to its shareholders. In addition, MAA may hold certain assets and engage in certain activities that a REIT could not engage in directly through its taxable REIT subsidiaries, or TRSs, and those TRSs will be subject to federal income tax at regular corporate rates on their taxable income without the benefit of the dividends paid deduction applicable to REITs.

Furthermore, we have a subsidiary that has elected to be treated as a REIT, and if our subsidiary REIT were to fail to qualify as a REIT, it is possible that we also would fail to qualify as a REIT unless we (or the subsidiary REIT) could qualify for certain relief provisions. The qualification of our subsidiary REIT as a REIT will depend on satisfaction, on an annual or quarterly basis, of numerous requirements set forth in highly technical and complex provisions of the Code for which there are only limited judicial or administrative interpretations. A determination as to whether such requirements are satisfied involves various factual matters and circumstances not entirely within our control. The fact that we hold substantially all of our assets through the Operating Partnership and its subsidiaries further complicates the application of the REIT requirements for us. No assurance can be given that our subsidiary REIT will qualify as a REIT for any particular year.

If Post Properties, or any other REIT previously acquired by us, failed to qualify as a REIT for U.S. federal income tax purposes, we would incur adverse tax consequences and our financial condition and results of operations would be materially adversely affected.

Prior to the Merger, Post Properties operated in a manner intended to allow it to qualify as a REIT for U.S. federal income tax purposes. If Post Properties, or any other REIT previously acquired by MAA (each, a "Merged REIT"), is determined to have lost its REIT status at any time prior to its merger with MAA, MAA would be subject to serious adverse tax consequences, including:

• MAA would be required to pay U.S. federal income tax at regular corporate rates on the taxable income of such Merged REIT without the benefit of the dividends paid deduction for the taxable years that the Merged REIT did not qualify as a REIT and for which the statute of limitations period remains open; and

• MAA would be required to pay any federal alternative minimum tax liability of the Merged REIT and any applicable state and local tax liability, in each case, for all taxable years that remain open under the applicable statute of limitations periods.

MAA is liable for any tax liability of a Merged REIT with respect to any periods prior to the merger of such Merged REIT with MAA. If a Merged REIT failed to qualify as a REIT, then in the event of a taxable disposition by MAA of an asset previously held by the Merged REIT during a specified period of up to 5 years following the merger of the Merged REIT with MAA, MAA will be subject to corporate income tax with respect to any built-in gain inherent in such asset as of the date of such merger. In addition, unless an applicable statutory relief provision applies, if a Merged REIT failed to qualify as a REIT for a taxable year, then the Merged REIT would not have been entitled to re-elect to be taxed as a REIT until the fifth taxable year following the year during which it was disqualified. Furthermore, if both MAA and a Merged REIT were "investment companies" under the "investment company" rules set forth in Section 368 of the Code at the time of the merger of MAA and such Merged REIT, the failure of MAA or such Merged REIT to have qualified as a REIT at the time of their merger could result in such merger being treated as taxable for federal income tax purposes. As a result of all these factors, the failure by a Merged REIT to have qualified as a REIT could jeopardize MAA’s qualification as a REIT and require the Operating Partnership to provide material amounts of cash to MAA to satisfy MAA’s additional tax liabilities and, therefore, could have a material adverse effect on MAA’s business prospects, financial condition or results of operations and on MAA’s ability to make payments on our debt and to make distributions.

The Operating Partnership may fail to be treated as a partnership for federal income tax purposes.

We believe that the Operating Partnership qualifies, and has so qualified since its formation, as a partnership for federal income tax purposes and not as a publicly traded partnership taxable as a corporation. No assurance can be provided, however, that the Internal Revenue Service, or IRS, will not challenge the treatment of the Operating Partnership as a partnership for federal income tax purposes or that a court would not sustain such a challenge. If the IRS were successful in treating the Operating Partnership as a corporation for federal income tax purposes, then the taxable income of the Operating Partnership would be taxable at regular corporate income tax rates. In addition, the treatment of the Operating Partnership as a

20

corporation would cause MAA to fail to qualify as a REIT. See "Failure to qualify as a REIT would cause us to be taxed as a corporation, which would significantly reduce funds available for distribution to shareholders" above.

Certain dispositions of property by us may generate prohibited transaction income, resulting in a 100% penalty tax on any gain attributable to the disposition.

                Any gain resulting from a transfer of property that we hold as inventory or primarily for sale to customers in the ordinary course of business would be treated for federal income tax purposes as income from a prohibited transaction that is subject to a 100% penalty tax.  Since we acquire properties for investment purposes, we do not believe that our occasional transfers or disposals of property would be considered prohibited transactions. Whether property is held for investment purposes is a question of fact that depends on all the facts and circumstances surrounding the particular transaction. As such, the IRS may contend that certain transfers or disposals of properties by us are prohibited transactions. If the IRS were to argue successfully that a transfer or disposition of property constituted a prohibited transaction, then we would be required to pay a 100% penalty tax on any gain allocable to us from the prohibited transaction. In addition, income from a prohibited transaction might adversely affect our ability to satisfy the income tests for qualification as a REIT for federal income tax purposes. A safe harbor to the characterization of the disposition of property as a prohibited transaction and the resulting imposition of the 100% tax is available; however, we cannot assure that we will be able to comply with such safe harbor in connection with any property dispositions.

The recently enacted legislation informally titled the Tax Cuts and Jobs Act and other legislative, regulatory and administrative developments may adversely affect MAA or its shareholders.

On December 22, 2017, President Trump signed into law P.L. 115-97, informally titled the Tax Cuts and Jobs Act, or the Tax Act. The Tax Act makes major changes to the Code, including a number of provisions of the Code that affect the taxation of REITs and their shareholders. Certain provisions of the Tax Act that may impact us and our shareholders include:

• temporarily reducing individual U.S. federal income tax rates on ordinary income; the highest individual U.S. federal income tax rate will be reduced from 39.6% to 37% (through taxable years ending in 2025);

• reducing the maximum corporate income tax rate from 35% to 21%;

• permitting a deduction for certain pass-through business income, including dividends received from REITs that are not designated as capital gain dividends or qualified dividend income, which generally will allow individuals, trusts and estates to deduct up to 20% of such amounts, resulting in an effective maximum U.S. federal income tax rate of 29.6% on such dividends (through taxable years ending in 2025);

• reducing the highest rate of withholding with respect to distributions to non-U.S. shareholders attributable to gains from the sale or exchange of U.S. real property interests from 35% to 21%;

• limiting the deduction for net operating losses to 80% of taxable income (prior to the application of dividends paid deduction);

• amending the limitation on the deduction of net interest expense for all businesses, other than certain electing businesses, including real estate businesses (which could adversely affect the taxation of any taxable REIT subsidiaries); and

• eliminating the corporate alternative minimum tax.

The individual and collective impact of these provisions and other provisions of the Tax Act on MAA and its shareholders is uncertain, and may not become evident for some period of time. In addition, other legislative, regulatory or administrative changes may be enacted or promulgated, either prospectively or with retroactive effect, and may adversely affect MAA or its shareholders. MAA's shareholders and prospective shareholders should consult their individual tax advisors regarding the implications of the Tax Act and other potential legislative, regulatory or administrative changes on their investment in MAA's capital stock.

ITEM 2. PROPERTIES.

We seek to acquire newer apartment communities and those with opportunities for repositioning through capital additions and management improvement located in the Southeast and Southwest regions of the United States with the potential for above average growth and return on investment. Approximately 68% of our apartment units are located in the Florida, Georgia, North Carolina, and Texas markets. Our strategic focus is to provide our residents high quality apartment units in attractive community settings, characterized by upscale amenities, extensive landscaping and attention to aesthetic detail.

Mortgage Financing

As of December 31, 2017, we had approximately $962.8 million of indebtedness collateralized, secured, and outstanding as set forth in Schedule III, Real Estate and Accumulated Depreciation.

ITEM 3. LEGAL PROCEEDINGS.

In September 2010, the United States Department of Justice, or the DOJ, filed suit against Post Properties (and by virtue of the Merger, MAA) in the United States District Court for the District of Columbia alleging that certain of our apartments violated accessibility requirements of the FHA and the ADA. The DOJ is seeking, among other things, an injunction against us, requiring us to retrofit the properties and comply with FHA and ADA standards in future design and construction, as well as monetary damages and civil penalties. No trial date has been set.

In December 2017, The Equal Rights Center, a non-profit civil rights organization, filed suit against MAA and the Operating Partnership in the United States District Court for the District of Columbia. This suit alleges that we maintained and enforced a criminal records screening policy at certain of our apartment communities, all of which are communities that we acquired from Post Properties in the Merger, which violates the FHA. The suit seeks injunctive relief, actual and punitive damages and attorneys' fees and costs.

In addition, we are involved in 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.

Market Information

MAA's common stock has been listed and traded on the NYSE under the symbol "MAA" since its initial public offering in February 1994. On February 16, 2018, the reported last sale price of our common stock on the NYSE was $88.75 per share, and there were approximately 2,800 holders of record of the common stock. MAA believes it has a significantly larger number of beneficial owners of its common stock. The following table sets forth the quarterly high and low intra-day sales prices of MAA's common stock and the dividends declared and paid by MAA with respect to the periods indicated.

	Sales Prices				Dividends Paid		Dividends Declared
	High		Low
2017:
First Quarter	$	103.64	$	92.50	$	0.8700	$	0.8700
Second Quarter	110.95		96.20		0.8700		0.8700
Third Quarter	109.25		99.06		0.8700		0.8700
Fourth Quarter	110.24		98.54		0.8700		0.9225		(1)
2016:
First Quarter	$	102.42	$	82.91	$	0.8200	$	0.8200

Fourth Quarter	98.35		85.04		0.8200		0.8700

⁽¹⁾ Generally, MAA's Board of Directors declares dividends prior to the quarter in which they are paid. The dividend declared in the fourth quarter of 2017 was paid on January 31, 2018 to shareholders of record on January 12, 2018.

23

MAA's quarterly dividend rate is currently $0.9225 per common share. MAA's Board of Directors reviews and declares the dividend rate quarterly. Actual dividends made by MAA will be affected by a number of factors, including, but not limited to, the gross revenues received from our apartment communities, our operating expenses, the interest expense incurred on borrowings and unanticipated capital expenditures. MAA expects to make future quarterly distributions to shareholders; however, future distributions by MAA will be at the discretion of its Board of Directors and will depend on our actual funds from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Code (see "Business - Qualification as a Real Estate Investment Trust" above) and such other factors as MAA's Board of Directors deems relevant.

Direct Stock Purchase and Distribution Reinvestment Plan

We have established the dividend and distribution reinvestment stock purchase plan, or DRSPP, under which holders of common stock, preferred stock and OP units can elect to automatically reinvest their distributions in shares of MAA common stock. The DRSPP also allows for the optional purchase of MAA common stock of at least $250, but not more than$5,000 in any given month, free of brokerage commissions and charges. In our absolute discretion, we may grant waivers to allow for optional cash payments in excess of $5,000. To fulfill our obligations under the DRSPP, we may either issue additional shares of common stock or repurchase common stock in the open market. We may elect to sell shares under the DRSPP at up to a 5% discount. In 2017, 2016, and 2015, we had issuances with no discounts through our DRSPP of 9,568 shares, 7,906 shares, and 8,562 shares, respectively.

Equity Compensation Plans

The following table provides information with respect to compensation plans under which our equity securities are authorized for issuance as of December 31, 2017:

Operating Partnership Units

There is no established public trading market for the Operating Partnership's OP Units. From time-to-time, we issue shares of MAA's common stock in exchange for OP Units tendered to the Operating Partnership for redemption in accordance with the provisions of the Operating Partnership’s limited partnership agreement. At December 31, 2017, there were 117,834,752 OP Units outstanding in the Operating Partnership, of which 113,643,166 OP Units, or 96.4%, were owned by MAA and 4,191,586 OP Units, or 3.6% were owned by limited partners. Under the terms of the Operating Partnership’s limited partnership agreement, the limited partner holders of OP Units have the right to require the Operating Partnership to redeem all or a portion of the OP Units held by the holder in exchange for one share of MAA common stock per one OP Unit or a cash payment based on the market value of our common stock at the time of redemption, at the option of MAA. During the year ended December 31, 2017, MAA issued a total of 28,813 shares of common stock upon redemption of OP Units.

24

At-the-Market Offering

On December 9, 2015, we entered into distribution agreements with J.P. Morgan Securities LLC, BMO Capital Markets Corp. and KeyBanc Capital Markets Inc. to sell up to an aggregate of 4.0 million shares of common stock, from time-to-time in at-the-market offerings or negotiated transactions through controlled equity offering programs, or ATMs. As of December 31, 2017, there were 4.0 million shares available to be sold under the ATMs.

Stock Repurchase Plan

On December 8, 2015, MAA's Board of Directors authorized the repurchase of up to 4.0 million shares of MAA common stock, which represented approximately 5.3% of MAA's common stock outstanding at the time of such authorization. This December 2015 authorization replaced and superseded a previous authorization from 1999, under which approximately 2.1 million shares remained to be repurchased at the time of the December 2015 authorization but through which no shares had been repurchased since April 2001.  From time to time, we may repurchase shares under the current authorization when we believe that shareholder value would be enhanced. Factors affecting this determination include, among others, the share price and expected rates of return. As of December 31, 2017, no shares have been repurchased under the current authorization.

Purchases of Equity Securities

The following table reflects repurchases of shares of MAA's common stock during the three months ended December 31, 2017:

ITEM 7. 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 96.4% limited partner interest as of December 31, 2017. MAA conducts all of its business through the Operating Partnership and its various subsidiaries. This discussion should be read in conjunction with the consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

MAA 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 and Southwest regions of the United States. As of December 31, 2017, activities include full ownership and operation of 301 multifamily properties, which includes commercial space at certain properties, four additional commercial properties, and a partial ownership in one multifamily property. These properties are located in Alabama, Arizona, Arkansas, Colorado, Florida, Georgia, Kansas, Kentucky, Maryland, Mississippi, Missouri, Nevada, North Carolina, South Carolina, Tennessee, Texas, Virginia and Washington, D.C.

Our primary business objectives are to protect and grow existing property values, to maintain a stable and increasing cash flow that will fund our dividends and distributions through all parts of the real estate investment cycle, and to create shareholder value by growing in a disciplined manner. To achieve these objectives, we intend to continue to pursue the following goals and strategies:

• effectively and efficiently operate our existing properties with an intense property and asset management focus and a decentralized structure;

• manage real estate cycles by taking an opportunistic approach to buying, selling, renovating and developing apartment communities;

28

• diversify investment capital across markets in which we operate to achieve a balanced portfolio with less volatile operating performance; and

• actively manage our capital structure to enhance predictability of earnings to fund our dividends and distributions.

OVERVIEW

We experienced an increase in net income available for MAA common shareholders for the year ended December 31, 2017 as the growth in revenues outpaced increases in our property operating expenses. The increase in revenues was primarily driven by a 3.0% increase in our Large Market Same Store segment, a 2.6% increase in our Secondary Market Same Store segment and a $375.2 million increase in our Non-Same Store and Other segment, which was primarily a result of the Merger. The increase in property operating expenses was primarily due to a 2.0% increase in our Large Market Same Store segment, a 2.7% increase in our Secondary Market Same Store segment and a $145.1 million increase in our Non-Same Store and Other segment, which was primarily the result of the Merger. The drivers of these increases are discussed below in the "Results of Operations" section.

On December 1, 2016, we consummated the Merger and acquired all of Post Properties' consolidated net assets. The consolidated net assets and results of operations of Post Properties are included in our consolidated financial statements from the closing date of the Merger going forward. All properties acquired from Post Properties are included in our Non-Same Store and Other operating segment, as the properties are recent acquisitions and had not been owned and stabilized for at least twelve months as of January 1, 2017.

Over the past three years, our growth has been driven by our acquisition strategy to invest in large and mid-sized growing markets in the Southeast and Southwest region of the United States. As a result of the Merger, we acquired 61 apartment communities in 2016. We acquired two apartment communities in 2017, five in 2016 apart from the Merger, and seven in 2015. We disposed of five apartment communities in 2017, 12 in 2016, and 21 in 2015.

TRENDS

During the year ended December 31, 2017, demand for apartments continued to be relatively strong, as it was during the year ended December 31, 2016. This strength was evident on two fronts: occupancy and effective rent per unit. Same store physical occupancy at December 31, 2017 was 97%. Average physical occupancy for the same store portfolio was 96.2% for the year ended December 31, 2017, consistent with the year ended December 31, 2016. Same store average effective rent per unit continued to increase, and was up 3.0% for the year ended December 31, 2017 as compared to the year ended December 31, 2016. As we move through the remainder of the typically slower winter leasing season and into the typically stronger spring leasing season, we believe the current level of physical occupancy puts us in a good position to capture solid pricing in the first half of 2018.

An important part of our portfolio strategy is to maintain a diversity of markets, submarkets, product types and price points across the Southeast and Southwest 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 and various monthly rent price points, will perform well in "up" cycles as well as weather "down" cycles better. Through our investment in 37 defined Metropolitan Statistical Areas, or MSAs, we are diversified across markets, urban and suburban submarkets, and a variety of monthly rent pricing points.

Current supply levels are impacting our total portfolio from a demand standpoint, particularly properties located in urban submarkets, the majority of which were acquired in the Merger. Properties in our same store portfolio have been impacted somewhat less by supply, primarily because less new development has occurred in those submarkets. Encouragingly, according to U.S. Census Bureau data, full year 2017 multifamily permitting across our markets was down 5% as compared to the prior year. This activity should result in relatively lower supply in our markets in the future as compared to the current environment.

Demand for our apartments is primarily driven by general economic conditions in our markets. In particular, job growth relative to new supply is a critical factor in our ability to maintain occupancy and increase rents. To the extent that the Tax Cuts and Jobs Act results in improving economic conditions such as increased job growth or more disposable income, we believe that we may be able to maintain occupancy more effectively and increase rents.

Also, we believe that more disciplined credit terms for residential mortgages should continue to favor rental demand at existing multifamily properties. Furthermore, rental competition from single family homes has not been a major competitive factor impacting our portfolio. For the year ended December 31, 2017, total move outs attributable to single family home

29

rentals for our combined portfolio represented about 6% of total move outs, in line with the year ended December 31, 2016. We have seen significant rental competition from single family homes in only a few of our submarkets. Long term, we expect demographic trends (including the growth of prime age groups for rentals and immigration and population movement to the Southeast and Southwest regions) will continue to support apartment rental demand in our markets.

Rising interest rates may have a significant impact on our business and results of operations. As of December 31, 2017, we had approximately $4.5 billion of debt, of which 17% had variable rate interest and 83% had fixed or hedged interest rates. To the extent interest rates rise, our net interest expense on variable rate debt will increase as will potentially our net interest expense on any debt refinancing. Given the short-term nature of our leases, to the extent interest rates rise due to general economic growth, we would expect increases in interest expense to be somewhat offset by positive leasing trends.

RESULTS OF OPERATIONS

Comparison of the Year Ended December 31, 2017 to the Year Ended December 31, 2016

For the year ended December 31, 2017, we achieved net income available for MAA common shareholders of $324.7 million, a 53.2% increase over the prior year, and total revenue growth of $403.6 million, a 35.9% increase over the prior year. The following discussion describes the primary drivers of the increase in net income for MAA common shareholders for the year ended December 31, 2017.

Property Revenues

The following table presents our property revenues by segment for the years ended December 31, 2017 and December 31, 2016 (dollars in thousands):

	December 31, 2017		December 31, 2016		Increase		% Increase
Large Market Same Store	$	672,131	$	652,560	$	19,571	3.0	%
Secondary Market Same Store	349,007		340,161		8,846		2.6	%
Same Store Portfolio	1,021,138		992,721		28,417		2.9	%
Non-Same Store and Other	507,849		132,627		375,222		282.9	%
Total	$	1,528,987	$	1,125,348	$	403,639	35.9	%

The increases in property revenues from our Large Market Same Store and Secondary Market Same Store portfolio were primarily a result of increased effective rent per unit of 3.1% and2.7%, respectively, as compared to the year ended December 31, 2016. The increase in property revenues from our Non-Same Store and Other portfolio was primarily the result of the Merger, as we classified the properties we acquired as Non-Same Store.

Property Operating Expenses

Property operating expenses include costs for property personnel, building repairs and maintenance, real estate taxes and insurance, utilities, landscaping, other operating expenses and depreciation and amortization. The following table reflects our property operating expenses by segment excluding depreciation and amortization for the years ended December 31, 2017 and December 31, 2016 (dollars in thousands):

	December 31, 2017		December 31, 2016		Increase		% Increase
Large Market Same Store	$	250,056	$	245,266	$	4,790	2.0	%
Secondary Market Same Store	130,334		126,888		3,446		2.7	%
Same Store Portfolio	380,390		372,154		8,236		2.2	%
Non-Same Store and Other	196,341		51,202		145,139		283.5	%
Total	$	576,731	$	423,356	$	153,375	36.2	%

The increase in property operating expenses for our Large Market Same Store segment was primarily the result of increases in real estate taxes of $4.7 million, personnel expenses of $1.0 million, and utilities expense of $0.7 million, partially offset by a decrease in insurance expense of $1.5 million. The increase in property operating expenses for our Secondary Market Same Store segment was primarily driven by increases in real estate taxes of $1.5 million, personnel expenses of $1.3 million, and utilities expense of $0.9 million, partially offset by a decrease in insurance expense of $0.3 million. The increase in property operating expenses for our Non-Same Store and Other portfolio was primarily due to the Merger.

Depreciation and Amortization

Depreciation and amortization expense for the year ended December 31, 2017 was approximately $493.7 million, an increase of $170.8 million from the year ended December 31, 2016. In addition to asset acquisitions made in the normal course of business, the increase was primarily driven by the full year of depreciation and amortization expense resulting from the Merger compared to only one month of comparable depreciation and amortization in 2016. As a result of the Merger, depreciation expense and amortization expense increased $138.2 million and $23.2 million, respectively, for year ended December 31, 2017 compared to the year ended December 31, 2016.

Other Operating Expenses

Property management expenses for the year ended December 31, 2017 were approximately $43.6 million, an increase of $9.5 million compared to the year ended December 31, 2016. The increase was primarily due to the growth in our portfolio as a result of the Merger.

Merger and integration expenses for the year ended December 31, 2017 were primarily comprised of $16.0 million of systems and professional costs and $4.0 million of legal costs, as we integrated Post Properties into our consolidated operations. Merger and integration expenses for the year ended December 31, 2017 were approximately $20.8 million less than merger and integration expenses for the year ended December 31, 2016, as we incurred significant merger related expenses in 2016 to complete the Merger on December 1, 2016.

General and administrative expenses for the year ended December 31, 2017 were approximately $40.2 million, an increase of $11.2 million compared to the year ended December 31, 2016. The increase was primarily driven by legal expenses.

Non-Operating Expenses and Other

Interest expense for the year ended December 31, 2017 was approximately $154.8 million, an increase of $24.8 million from the year ended December 31, 2016. The increase was primarily due to increased borrowing as we assumed several loans as a result of the Merger, including a secured loan with a face value of $186.0 million and two unsecured loans with face values of $150.0 million and $250.0 million, respectively. We entered into a new $300.0 million term loan on the closing date of the Merger. Interest expense for the year ended December 31, 2017 increased $16.0 million due to these borrowings resulting from the Merger. In addition, in May 2017, we publicly issued senior unsecured notes with a face value of $600.0 million, bearing interest at 3.60% per annum, which resulted in additional interest expense of approximately $14.0 million for the year ended December 31, 2017. Such increases were offset by a slight decreases in interest expense as a result of retirements of secured property mortgages and unsecured notes during the year ended December 31, 2017; the notes were scheduled to mature in October 2017.

Gains on sale of depreciable assets totaled $127.4 million for the year ended December 31, 2017, an increase of approximately $47.0 million from the year ended December 31, 2016. Although disposition activity decreased year-over-year, the gain on sale of depreciable assets increased primarily due to the nature of the real estate assets sold.

Other non-operating income for the year ended December 31, 2017 was $14.4 million, an increase of approximately $16.2 million compared to the year ended December 31, 2016. The year-over-year increase was primarily due to an $8.8 million increase in the net mark-to-market adjustments of the bifurcated embedded derivative related to the MAA Series I preferred stock issued in the Merger. The year-over-year increase was also driven by the $3.3 million increase in the net gain on debt extinguishment, primarily due to gains of $4.8 million from the write-offs of mark-to-market debt adjustments related to the retirement of secured mortgages and a term loan, partially offset by a cash prepayment penalty of $1.6 million.

During the year ended December 31, 2017 we recorded quarterly dividend distributions to holders of MAA's Series I preferred stock totaling $3.7 million. As there were no shares of MAA Series I preferred stock issued and outstanding until completion of the Merger on December 1, 2016, preferred dividends only impacted our results of operations for one month totaling $0.3 million for the year ended December 31, 2016.

Comparison of the Year Ended December 31, 2016 to the Year Ended December 31, 2015

For the year ended December 31, 2016, we achieved net income available for MAA common shareholders of $211.9 million, a 36.2% decrease over the prior year, and total revenue growth of $82.6 million, a 7.9% increase over the prior year.

31

The following discussion describes the primary drivers of the decrease in net income for MAA common shareholders for the year ended December 31, 2016.

The comparison of the year ended December 31, 2016 to the year ended December 31, 2015 shows the segment break down based on the 2016 same store portfolios. A comparison using the 2017 same store portfolio would not be comparative due to the nature of the classifications.

Property Revenues

The following table presents our property revenues by segment for the years ended December 31, 2016 and December 31, 2015 (dollars in thousands):

	December 31, 2016		December 31, 2015		Increase		% Increase
Large Market Same Store	$	642,679	$	612,934	$	29,745	4.9	%
Secondary Market Same Store	337,883		327,700		10,183		3.1	%
Same Store Portfolio	980,562		940,634		39,928		4.2	%
Non-Same Store and Other	144,786		102,145		42,641		41.7	%
Total	$	1,125,348	$	1,042,779	$	82,569	7.9	%

The increase in property revenues from our same store portfolio was primarily a result of increased effective rent per unit of 4.9% and 2.9% for our large and secondary markets, respectively. The increase in property revenues from our Non-Same Store and Other segment was due to the Merger.

Property Operating Expenses

Property operating expenses include costs for property personnel, building repairs and maintenance, real estate taxes and insurance, utilities, landscaping, other operating expenses and depreciation and amortization. The following table reflects our property operating expenses excluding depreciation and amortization by segment for the years ended December 31, 2016 and December 31, 2015 (dollars in thousands):

	December 31, 2016		December 31, 2015		Increase		% Increase
Large Market Same Store	$	243,392	$	235,909	$	7,483	3.2	%
Secondary Market Same Store	125,830		123,318		2,512		2.0	%
Same Store Portfolio	369,222		359,227		9,995		2.8	%
Non-Same Store and Other	54,134		41,418		12,716		30.7	%
Total	$	423,356	$	400,645	$	22,711	5.7	%

The increase in property operating expenses from our Large Market Same Store segment was primarily the result of increases in real estate taxes of $5.3 million, personnel expenses of $1.5 million and utilities expenses of $1.2 million. The increase in property operating expenses from our Secondary Market Same Store segment was primarily driven by increases in real estate taxes of $1.3 million.The increase in property operating expenses from our Non-Same Store and Other segment was due to the Merger.

Depreciation and Amortization

Depreciation and amortization expense for the year ended December 31, 2016 was $323.0 million, an increase of $28.4 million, from the year ended December 31, 2015. The increase was primarily driven by depreciation expense of $17.4 million related to the Merger. Additionally, the amortization of the fair market value of in-place leases related to the Merger began in December 2016, and totaled $4.9 million for the year ended December 31, 2016.

Other Operating Expenses

Merger and integration expenses for the year ended December 31, 2016 were $40.8 million as a result of the expenses associated with the Merger, which closed on December 1, 2016. There were no merger and integration expenses for the year ended December 31, 2015 as no merger occurred in that year.

Interest expense for the year ended December 31, 2016 was approximately $129.9 million, an increase of $7.6 million from the year ended December 31, 2015. The increase was due in part to decreased amortization of the fair market value of

32

debt adjustments related to debt acquired and increased interest rates towards the end of 2016. Additionally, we assumed additional debt as a result of the Merger, including a secured loan in the principal amount of $186.0 million and two series of unsecured senior notes with face values of $150.0 million and $250.0 million, respectively. Additionally, we entered into a new $300.0 million term loan on the closing date of the Merger.

We recorded a gain on sale of depreciable assets of $80.4 million for the year ended December 31, 2016, a decrease of approximately $109.6 million from the year ended December 31, 2015. The decrease was primarily the result of a decline in disposition activity year-over-year. Dispositions decreased from 21 multifamily properties for the year ended December 31, 2015, to 12 multifamily properties for the year ended December 31, 2016.

Non-Operating Expenses and Other

Other non-operating expense for the year ended December 31, 2016 was $1.8 million, a decrease of approximately $4.4 million compared to the year ended December 31, 2015. The year-over-year decrease was primarily due to the $3.5 million decrease in loss on debt extinguishment due to the 2015 removal of properties from a secured tax-free debt facility; there was an immaterial loss on debt extinguishment activity for the year ended December 31, 2016.

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 extraordinary items, asset impairment and gains or losses on disposition of real estate assets, plus net income attributable to noncontrolling interests, depreciation and amortization of real estate, and adjustments for joint ventures to reflect FFO on the same basis. Because noncontrolling interest is added back, FFO, when used in this Annual Report on Form 10-K, represents FFO attributable to the Company.

FFO should not be considered as an alternative to net income or any other GAAP measurement of performance, as an indicator of operating performance or as an alternative to cash flows 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 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.

The following table presents a reconciliation of net income available for MAA common shareholders to FFO for the years ended December 31, 2017, 2016, and 2015, as we believe net income available for MAA common shareholders is the closest corresponding GAAP measure (dollars in thousands):

	Year ended December 31,
	2017			2016			2015
Net income available for MAA common shareholders	$	324,691		$	211,915		$	332,287
Depreciation and amortization of real estate assets	489,503			319,528			291,572
Gain on sale of depreciable real estate assets	(127,386		)	(80,397		)	(189,958		)
Loss (gain) on disposition within unconsolidated entities	—			98			(12		)
Depreciation and amortization of real estate assets of real estate joint ventures	596			61			25
Net income attributable to noncontrolling interests	12,157			12,180			18,458
Funds from operations attributable to the Company	$	699,561		$	463,385		$	452,372

FFO for the year ended December 31, 2017 increased by approximately $236.2 million from the year ended December 31, 2016 primarily as a result of the increases in property revenues of $403.6 million and other non-operating income of $16.2 million, in addition to decreased merger and integration expenses of $20.8 million. The increases to FFO were offset by the impact of increases in property operating expenses, excluding depreciation and amortization, of $153.4 million, interest expense of $24.8 million, general and administrative expenses of $11.2 million, property management expenses of $9.5 million and preferred dividends of $3.4 million.

33

FFO for the year ended December 31, 2016 increased by approximately $11.0 million from the year ended December 31, 2015 primarily as a result of the increase in property revenues of $82.6 million, which was offset by increases in merger and integration expenses of $40.8 million, property operating expenses, excluding depreciation and amortization, of $22.7 million, general and administrative expenses of $3.3 million and property management expenses of $3.1 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 flow provided by operating activities increased to $658.5 million for the year ended December 31, 2017 from $484.0 million for the year ended December 31, 2016. The increase was primarily driven by the inclusion of twelve months of operating results of Post Properties for the year ended December 31, 2017 as compared to one month of operating results for the year ended December 31, 2016.

Investing Activities

Net cash used in investing activities for the year ended December 31, 2017 was $283.4 million compared to net cash used in investing activities for the year ended December 31, 2016 of $710.5 million. The primary drivers of the change were as follows:

	Primary drivers of cash inflow (outflow)						Increase (Decrease) in Net Cash			Percentage Increase (Decrease) in Net Cash
	during the year ended December 31,
	2017			2016
Purchases of real estate and other assets	$	(136,065	)	$	(339,186	)	$	203,121		59.9	%
Capital improvements, development and other	(343,890		)	(183,977		)	(159,913		)	(86.9	)%
Proceeds from disposition of real estate assets	187,429			296,700			(109,271		)	(36.8	)%
Return (funding) of escrow for future acquisitions	10,591			(58,259		)	68,850			118.2	%
Acquisition of Post Properties, net of cash acquired	—			(427,764		)	427,764			(100.0	)%

The decrease in cash outflows for purchases of real estate and other assets resulted from the acquisition of two apartment communities during the year ended December 31, 2017 compared to the acquisition of five apartment communities during the year ended December 31, 2016. The increase in cash outflows for capital improvements, development and other during the year ended December 31, 2017 compared to the prior year resulted from the property portfolio increase and development pipeline increase as a result of the Merger. The decrease in proceeds from the disposition of real estate assets primarily resulted from the sale of five apartment communities and four land parcels during the year ended December 31, 2017 compared to the sale of 12 apartment communities, one commercial property, and three land parcels during the year ended December 31, 2016. The increase in cash inflows from the funding of escrow for future acquisitions resulted from the funding of three anticipated future 1031(b) transactions offset by the release of three 1031(b) transactions that never occurred during the year ended December 31, 2017 compared to the funding of one anticipated future 1031(b) transaction during the year ended December 31, 2016. The decrease in cash outflows for the acquisition of Post Properties, net of cash acquired, compared to prior year resulted from the completion of the Merger; there were no mergers during the year ended December 31, 2017.

34

Financing Activities

Net cash used by financing activities was $397.9 million for the year ended December 31, 2017 compared to net cash provided by financing activities of $222.4 million for the year ended December 31, 2016. The primary drivers of the change were as follows:

	Primary drivers of cash inflow (outflow)						Increase (Decrease) in Net Cash			Percentage Increase (Decrease) in Net Cash
	during the year ended December 31,
	2017			2016
Net change in credit lines	$	(160,000	)	$	335,000		$	(495,000	)	(147.8	)%
Proceeds from notes payable	597,480			300,000			297,480			99.2	%
Principal payments on notes payable	(413,557		)	(146,026		)	(267,531		)	(183.2	)%
Dividends paid on common shares	(395,294		)	(247,652		)	(147,642		)	(59.6	)%

The decrease in cash outflows related to the net change in credit lines resulted from the decrease in net borrowings of $80.0 million on our unsecured revolving credit facility and $80.0 million on our secured credit facility during the year ended December 31, 2017, compared to an increase in net borrowings of $415.0 million on the unsecured revolving credit facility and a decrease of $80.0 million on the secured credit facility during the year ended December 31, 2016. The increase in proceeds from notes payable during the year endedDecember 31, 2017related to the May 2017 issuance of $600.0 million senior unsecured notes, as discussed in Note 6, compared to the 2016 issuance of the unsecured term loan in the amount of $300.0 million. The increase in cash outflows from principal payments on notes payable primarily resulted from paying off approximately $233.6 million of secured property mortgages and $168.0 million of senior unsecured notes during the year endedDecember 31, 2017compared to paying off the $140.0 million legacy Post Properties' line of credit facility during the year endedDecember 31, 2016. The increase in cash outflows from dividends paid on common shares primarily resulted from the increased number of common shares outstanding as a result of the Merger and the increase in the annual dividend rate to$3.48per share during the year endedDecember 31, 2017compared to the dividend rate of$3.28per share during the year endedDecember 31, 2016.

Equity

As of December 31, 2017, MAA owned 113,643,166 OP Units, comprising a 96.4% limited partnership interest in the Operating Partnership, while the remaining 4,191,586 outstanding OP Units were held by third party limited partners of the Operating Partnership. Holders of OP Units (other than MAA and its corporate affiliates) 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 the 4,191,586 shares of its common stock, that as of December 31, 2017, were issuable upon redemption of OP Units, so that those shares can be sold freely in the public markets.

As of December 31, 2017, we had entered into interest rate swaps totaling a notional amount of $550.0 million related to issued debt. To date, these swaps have proven to be highly effective hedges. We had also entered into an interest rate cap agreement totaling a notional amount of $25.0 million as of December 31, 2017.

Unsecured Revolving Credit Facility

On October 15, 2015, the Operating Partnership entered into an unsecured revolving credit facility agreement with a syndicate of banks led by KeyBank National Association, or KeyBank, and fourteen other banks, the KeyBank Facility. The KeyBank Facility replaced our Operating Partnership's previous unsecured credit facility with KeyBank. The interest rate is determined using an investment grade pricing grid using LIBOR plus a spread of 0.85% to 1.55%. On December 1, 2016, the Operating Partnership amended the KeyBank Facility by increasing the borrowing capacity from $750.0 million to $1.0 billion. As of December 31, 2017, we had $410.0 million borrowed under the KeyBank Facility, bearing interest at a rate of LIBOR plus 0.90%. The KeyBank Facility serves as our primary source of short-term liquidity and has an accordion feature that we may use to expand its capacity to $1.5 billion. This facility matures on April 15, 2020, with an option to extend for an additional six months.

Senior Unsecured Notes

We have also issued both public and private unsecured notes. As of December 31, 2017, we had approximately $2.0 billion (face value) of publicly issued notes and $292.0 million of unsecured notes issued in two private placements.  In October 2013, we publicly issued $350.0 million of senior unsecured notes due 2023 with a coupon of 4.30%, paid semi-annually on April 15 and October 15. In June 2014, we publicly issued $400.0 million of senior unsecured notes due 2024 with a coupon of 3.75%, paid semi-annually on June 15 and December 15.  In November 2015, we publicly issued $400.0 million senior unsecured notes due 2025 with a coupon of 4.00%, paid semi-annually on May 15 and November 15. As a result of the Merger in December 2016, we assumed two series of publicly issued senior notes totaling $400.0 million. One series of senior notes assumed as a result of the Merger has a face value of $250.0 million, is due 2022, and has a coupon of 3.38% paid semi-annually on June 1 and December 1. The other series of senior notes assumed as a result of the Merger had a face value of $150.0 million and was due in October 2017, but was paid off in July 2017. In May 2017, we publicly issued $600.0 million of senior unsecured notes due June 1, 2027 with a coupon of 3.60%, paid semi-annually on June 1 and December 1. The proceeds from the senior unsecured notes issued in May 2017 were used to pay down outstanding amounts of the Key Bank Facility. As of December 31, 2017, all of these amounts, with the exception of the series of senior unsecured notes assumed in the Merger with a face value of $150.0 million that was paid off in July 2017, remained outstanding.

In July 2011, we issued $135.0 million of senior unsecured notes. The notes were offered and sold in a private placement with three maturity tranches: $50.0 million at 4.7% maturing on July 29, 2018, $72.8 million at 5.4% maturing on July 29, 2021; and $12.3 million at 5.6% maturing on July 29, 2023; all of which were outstanding at December 31, 2017. On August 31, 2012, we issued $175.0 million of senior unsecured notes. The notes were offered and sold in a private placement with four tranches: $18.0 million at 3.15% maturing on November 30, 2017; $20.0 million at 3.61% maturing on November 30, 2019; $117.0 million at 4.17% maturing on November 30, 2022; and $20.0 million at 4.33% maturing on November 30, 2024. The $18 million tranche was paid off on its maturity date. The remaining tranches were outstanding as of December 31, 2017.

Unsecured Term Loans

In addition to the KeyBank Facility, we maintain four unsecured term loans. We had total borrowings of $850.0 million outstanding under these term loan agreements at December 31, 2017, comprised of:     

A $250.0 million term loan with Wells Fargo, N.A., or Wells Fargo, that bears interest at a rate of LIBOR plus a spread of 0.90% to 1.90% based on the credit ratings of our unsecured debt. The loan matures on August 1, 2018. As of December 31, 2017, this loan was bearing interest at a rate of LIBOR plus 0.98%.

A $150.0 million term loan with U.S. Bank National Association, or U.S. Bank, that bears interest at a rate of LIBOR plus a spread of 0.90% to 1.90% based on the credit ratings of our unsecured debt. The loan matures on March 1, 2020. As of December 31, 2017, this loan was bearing interest at a rate of LIBOR plus 0.98%.

A $150.0 million term loan with Key Bank that bears interest at a rate of LIBOR plus a spread of 0.90% to 1.75% based on the credit ratings of our unsecured debt. The loan matures on March 1, 2021. As of December 31, 2017, this loan was bearing interest at a rate of LIBOR plus 0.95%.

A $300.0 million term loan with Wells Fargo that bears interest at a rate of LIBOR plus a spread of 0.90% to 1.75% based on the credit ratings of our unsecured debt. The loan matures on March 1, 2022. As of December 31, 2017, this loan was bearing interest at a rate of LIBOR plus 0.95%.

37

Secured Property Mortgages

We also maintain secured property mortgages with Fannie Mae, Freddie Mac and various life insurance companies. These mortgages are usually fixed rate and can range from five to ten years in maturity. As of December 31, 2017, we had $882.8 million of secured property mortgages.

Secured Credit Facility

Approximately 1.8% of our outstanding obligations at December 31, 2017 were borrowed through a credit facility with Prudential Mortgage Capital, which is credit enhanced by Fannie Mae, or the Fannie Mae Facility. The Fannie Mae Facility has a combined line limit of $80.0 million, of which $80.0 million was collateralized, available to borrow, and borrowed, at December 31, 2017. The Fannie Mae Facility matures in 2018.

⁽¹⁾Fixed rate and swapped interest are reflected in this table. The average interest rates of variable rate debt are presented in preceding tables.

⁽²⁾Represents principal payments gross of discounts, debt issuance costs and fair market value adjustments of debt assumed.

⁽³⁾Swapped interest is subject to the ineffective portion of cash flow hedges as described in Note 7 to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K. 

⁽⁴⁾Represents development fees.

⁽⁵⁾Primarily comprised of a ground lease underlying one apartment community we own.

We have a commitment, which is not reflected in the table above, to make additional capital contributions to a limited partnership in which we hold an equity interest. The capital contributions may be called by the general partner at any time until September 2022 after giving appropriate notice. At December 31, 2017, we had committed to make additional capital contributions totaling up to $13.5 million if and when called by the general partner of the limited partnership and prior to September 2022.

Off-Balance Sheet Arrangements

At December 31, 2017, and 2016, 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.

As of December 31, 2017, we had a 35.0% ownership interest in a limited liability company, which owns one apartment community comprised of 269 units, located in Washington, D.C. We also had a 31.0% ownership interest in a limited partnership. Our interests in these investments are unconsolidated and are recorded using the equity method for the investments as we do not have a controlling interest.

In addition, we do not engage in trading activities involving non-exchange traded contracts. As such, we are not materially exposed to 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 13 to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

38

INSURANCE

We carry comprehensive general liability coverage on our 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 each property, including loss of rental income during the reconstruction period.

We renegotiated our primary insurance programs effective July 1, 2017. 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 operation.

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. Almost all 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

A critical accounting policy is one that is both important to our financial condition and results of operations and that involves some degree of uncertainty. The preceding discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements and the notes thereto, which have been prepared in accordance with GAAP. The preparation of financial statements in conformity with GAAP requires management to make a number of estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements. On an ongoing basis, we evaluate our estimates and assumptions based upon historical experience and various other factors and circumstances. We believe that our estimates and assumptions are reasonable under the circumstances; however, actual results may differ from these estimates and assumptions.

We believe that the estimates and assumptions listed below are most important to the portrayal of our financial condition and results of operations because they require the greatest subjective determinations and form the basis of accounting policies deemed to be most critical.

Acquisition of real estate assets

We account for our acquisitions of investments in real estate as asset acquisitions in accordance with ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which requires the cost of the of the real estate acquired to be allocated to the individual acquired tangible assets, consisting of land, buildings and improvements and other, and identified intangible assets, consisting of the value of in-place leases and other contracts, on a relative fair value basis. In calculating the total asset value of acquired tangible assets, management uses stabilized net operating income, or NOI, and market specific capitalization and discount rates. Management analyzed historical stabilized NOI to determine its estimate for forecasted NOI. Management estimates the market capitalization rate by analyzing the market capitalization rates for properties with comparable ages in similarly sized markets. Management then allocates the purchase price of the asset acquisition based on the relative fair value of the individual components as a proportion of the total assets acquired.

Impairment of long-lived assets

We account for long-lived assets in accordance with the provisions of accounting standards for the impairment or disposal of long-lived assets. We periodically evaluate long-lived assets, including investments in real estate, for indicators that would suggest that the carrying amount of the assets may not be recoverable. The judgments regarding the existence of such indicators are based on factors such as operating performance, market conditions and legal factors. Long-lived assets, such as real estate assets, equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset, which is estimated by analyzing historical cash flows of the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. We calculate the fair value of an asset by dividing historical operating cash flows by a market capitalization rate. We estimate the market capitalization rate by analyzing the market capitalization rates for properties with comparable ages in similarly sized markets. No material impairment losses have been recognized

39

during the years ended December 31, 2017, 2016, and 2015.

Cost capitalization

In conformity with GAAP, we capitalize those expenditures that materially enhance the value of an existing asset or substantially extend the useful life of an existing asset. Expenditures necessary to maintain an existing property in ordinary operating condition are expensed as incurred. Therefore, repairs and maintenance costs are expensed as incurred while significant improvements, renovations, and replacements are capitalized. The cost to complete any deferred repairs and maintenance at properties acquired by us in order to elevate the condition of the property to our standards are capitalized as incurred. The carrying costs related to development projects, including interest, property taxes, insurance and allocated direct development salary cost during the construction period, are capitalized. Management uses judgment in determining whether costs should be expensed or capitalized. See Note 1 to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K for additional detail.

Loss contingencies

The outcomes of claims, disputes and legal proceedings are subject to significant uncertainty. We record an accrual for loss contingencies when a loss is probable and the amount of the loss can be reasonably estimated. We review these accruals quarterly and make revisions based on changes in facts and circumstances. When a loss contingency is not both probable and reasonably estimable, then we do not accrue the loss. However, for material loss contingencies, if the unrecorded loss (or an additional loss in excess of the accrual) is at least a reasonable possibility and material, then we disclose a reasonable estimate of the possible loss, or range of loss, if such reasonable estimate can be made. If we cannot make a reasonable estimate of the possible loss, or range of loss, then that 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 that we consider in this assessment, including with respect to the matters disclosed in this Annual Report on Form 10-K, 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, our experience in similar matters, the facts available to us at the time of assessment, and how we intend to respond, or have responded, to the proceeding or claim. Our assessment of these factors may change over time as individual proceedings or claims progress. For matters where we are 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 expected ultimately to be resolved through negotiation and settlement have not reached the point where we believe a reasonable estimate of loss, or range of loss, can be made. In such instances, we believe that there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss or business impact, if any.

For more information regarding our significant accounting policies, including a brief description of recent accounting pronouncements that could have a material impact on our financial statements, see Note 1 to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

ITEM 7A. 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. At December 31, 2017, 27.5% of our total capitalization consisted of 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 and caps, which mitigate our interest rate risk on a related financial instrument and effectively fix or cap the interest rate on a portion of our variable debt 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. At December 31, 2017, approximately 83.0% of our outstanding debt was subject to fixed or capped rates after considering related derivative instruments We regularly review interest rate exposure on outstanding borrowings in an effort to minimize the risk of interest rate fluctuations.

The table below provides information about our financial instruments that are sensitive to changes in interest rates. For debt obligations, the table presents principal cash flows and related weighted average interest rates by expected maturity dates. For our interest rate swaps and cap, the table presents the notional amount of the swaps and cap and the years in which they expire. Weighted average variable rates are based on rates in effect at the reporting date (dollars in thousands).

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Mid-America Apartment Communities, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Mid-America Apartment Communities, Inc. (the Company) as of December 31, 2017 and 2016, the related consolidated statements of operations, comprehensive income, equity, and cash flows for each of the three years in the period ended December 31, 2017, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 22, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

To the Partners of Mid-America Apartments, L.P.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Mid-America Apartments, L.P. (the Partnership) as of December 31, 2017 and 2016, the related consolidated statements of operations, comprehensive income, changes in capital, and cash flows for each of the three years in the period ended December 31, 2017, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Partnership at December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on the Partnership's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Partnership is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Partnership’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Mid-America Apartment Communities, Inc.

Opinion on Internal Control over Financial Reporting

We have audited Mid-America Apartment Communities, Inc.’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Mid-America Apartment Communities, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2017 and 2016, the related consolidated statements of operations, comprehensive income, equity, and cash flows for each of the three years in the period ended December 31, 2017, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) and our report dated February 22, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

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

Notes to Consolidated Financial Statements

Years ended December 31, 2017, 2016, and 2015

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" refers 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" means 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 December 31, 2017, MAA owned 113,643,166 OP Units (or approximately 96.4% of the total number of OP units). MAA conducts substantially all of its business and holds substantially all of its assets 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 consolidated financial statements of MAA and MAALP 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 is a multifamily focused, self-administered and self-managed real estate 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 partner interests in the Operating Partnership; therefore, MAA does not conduct business itself, other than 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 OP Units, 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 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. Redeemable common units represent the number of outstanding OP Units as of the date of the applicable balance sheet, valued at the greater of the closing market price of MAA's common stock or the aggregate value of the individual partners' capital balances. Holders of OP Units (other than MAA and its corporate affiliates) 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.

F-14

Organization of Mid-America Apartment Communities, Inc.

On December 1, 2016, MAA completed a merger with Post Properties, Inc., or Post Properties. Pursuant to the Agreement and Plan of Merger, or the Merger Agreement, Post Properties merged with and into MAA, with MAA continuing as the surviving corporation, or the Parent Merger, and Post Apartment Homes, L.P., or Post LP, merged with and into MAALP, with MAALP continuing as the surviving entity, or the Partnership Merger. The Company refers to the Parent Merger, together with the Partnership Merger, as the Merger in this Annual Report on Form 10-K. Under the terms of the Merger Agreement, each share of Post Properties common stock was converted into the right to receive 0.71 of a newly issued share of MAA common stock, including the right, if any, to receive cash in lieu of fractional shares of MAA common stock. In addition, each limited partner interest in Post LP designated as a "Class A Unit" automatically converted into the right to receive 0.71 of a newly issued partnership unit of MAALP. Also, each share of Post Properties' 8 1/2% Series A Cumulative Redeemable Preferred Stock, which is referred to as the Post Properties Series A preferred stock, was automatically converted into the right to receive one newly issued share of MAA's 8.50% Series I Cumulative Redeemable Preferred Stock, $0.01 par value per share, which is referred to as MAA Series I preferred stock. Each newly issued share of MAA Series I preferred stock has substantially the same rights, preferences, privileges, and voting powers as those of the Post Properties Series A preferred stock. The net assets and results of operations of Post Properties are included in the consolidated financial statements from the closing date going forward. See further discussion regarding the Merger in Note 2.

As of December 31, 2017, the Company owned and operated 301 apartment communities through the Operating Partnership. As of December 31, 2017, MAA also owned a 35.0% interest in an unconsolidated real estate joint venture and a 31.0% interest in an unconsolidated limited partnership. As of December 31, 2017, the Company had three development communities under construction totaling 937 apartment units, of which 240 units were completed during the year. Total expected costs for these three development projects are $214.0 million, of which $167.7 million had been incurred through December 31, 2017. The Company expects to complete construction on one project by the first quarter of 2018, one project by the third quarter of 2018 and one project by the fourth quarter of 2018. Twenty-nine of the multifamily properties include retail components with approximately 620,000 square feet of gross leasable space. The Company also has four wholly-owned commercial properties, which were acquired through the Merger, with approximately 230,000 square feet of combined gross leasable area.

Basis of Presentation and Principles of Consolidation

The accompanying 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 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 approximately 92.5% to 100% of all consolidated subsidiaries, including the Operating Partnership. The 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, 92.5% to 100% of all consolidated subsidiaries. In management's opinion, all adjustments necessary for a fair presentation of the 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, since 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 "Investment in Unconsolidated Affiliates" below).

Changes in Presentation

In an effort to align the Company's presentation of assets, liabilities and equity in the Consolidated Balance Sheets with the presentation utilized by competitors in its industry and to enhance comparability, the Company combined "Buildings and

F-15

improvements", "Furniture, fixtures and equipment" and "Corporate properties, net" into one line item "Buildings and improvements and other." The Company also combined "Deferred financing costs, net", "Other assets", and "Goodwill" into a single line item "Other assets." Finally, the Company aggregated "Accounts payable", "Fair market value of interest rate swaps", "Security deposits" and "Accrued expenses and other liabilities" into one line item "Accrued expenses and other liabilities". Prior year amounts have been changed to conform to the Company's current year presentation. These changes in presentation had no effect on the Company's total assets or total liabilities and equity.

In an effort to align the Company's presentation of revenues and expenses in the Consolidated Statements of Operations with the presentation utilized by competitors in its industry and to enhance comparability, the Company combined "Rental revenues", "Other property revenues" and "Management fee income" into one line item "Rental and other property revenues". The Company also combined "Personnel", "Building repairs and maintenance", "Utilities", "Landscaping" and "Other operating" into one line item "Operating expense, excluding real estate taxes." Additionally, the Company combined "Merger related expense" and "Integration expense" into one line item "Merger and integration expense." Further, the Company aggregated the line items "Acquisition expense", "Interest and other non-property income (expense)", "Loss on debt extinguishment" and "Net casualty loss (gain)" into a single line item "Other non-operating expense." Prior year amounts have been changed to conform to the Company's current year presentation. These changes in presentation had no effect on the Company's net income.

In an effort to align the Company's presentation of cash flows from operating activities and investing activities within the Consolidated Statements of Cash Flows with the presentation utilized by competitors in its industry and to enhance comparability, the Company combined "Retail revenue accretion"; "Redeemable stock expense"; "Gain (loss) from investments in real estate joint venture"; "Gain (loss) on debt extinguishment"; "Derivative interest credit"; "Settlement of forward swaps"; "Net casualty gain (loss)" and "Changes in restricted cash, other assets, accounts payable, accrued expenses and security deposits" into one line "Net change in operating accounts and other" within the cash flows from operating activities section. In addition, the Company aggregated "Normal capital improvements", "Construction capital and other", "Renovations to existing assets" and "Development" into one line "Capital improvements, development and other" within the cash flows from investing activities section. No presentation changes were made to the cash flows from financing activities section of the Consolidated Statements of Cash Flows. Prior year amounts have been changed to conform to the Company's current year presentation. These changes in presentation had no effect on the Company's ending cash and cash equivalents balance and did not impact the classification of cash flows between operating, investing and financing activities.

Noncontrolling Interests

At December 31, 2017, the Company had two types of noncontrolling interests, (1) noncontrolling interests related to the common unitholders of its Operating Partnership (see Note 10) and (2) noncontrolling interest related to its consolidated real estate entity (see "Investment in Consolidated Real Estate Joint Venture" below).

Use of Estimates

Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses to prepare these financial statements and notes in conformity with GAAP. Actual results could differ from those estimates.

Revenue Recognition and Real Estate Sales Gain Recognition

The Company primarily leases multifamily residential apartments under operating leases generally with terms of one year or less, which are recorded as operating leases. Rental lease revenues are recognized in accordance with Accounting Standards Codification, or ASC, 840, Leases, using a method that represents a straight-line basis over the term of the lease. Rental income represents gross market rent less adjustments for concessions, vacancy loss and bad debt. Other non-lease revenues are recognized in accordance with ASC, 605, Revenue Recognition, when such sources of revenue are earned, and the amounts are fixed and determinable. The Company records gains and losses on real estate sales in accordance with accounting standards governing the sale of real estate. For sale transactions meeting the requirements for the full accrual method, the Company removes the assets and liabilities from its Consolidated Balance Sheets and recognizes the gain or loss in the period the transaction closes.

Rental Costs

Costs associated with rental activities are expensed as incurred and include advertising expenses, which were approximately$18.8 million, $13.0 million, and $13.5 million for the years ended December 31, 2017, 2016, and 2015, respectively.

F-16

Real Estate Assets and Depreciation and Amortization

Real estate assets are carried at depreciated cost and consist of land, buildings and improvements and other and development and capital improvements in progress (see "Development Costs" below). Repairs and maintenance costs are expensed as incurred, while significant improvements, renovations, and recurring capital replacements are capitalized and depreciated over their estimated useful lives. Recurring capital replacements typically include scheduled carpet replacement, new roofs, HVAC units, plumbing, concrete, masonry and other paving, pools and various exterior building improvements. In addition to these costs, the Company also capitalizes salary costs directly identifiable with renovation work. These expenditures extend the useful life of the property and increase the property’s fair market value. The cost of interior painting, vinyl flooring and blinds are expensed as incurred.

Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets, which range from five to 40 years. The Consolidated Balance Sheets line "Buildings and improvements and other" includes land improvements and buildings, which have a useful life ranging from eight to 40 years, as well as furniture, fixtures and equipment, which have a useful life of five years.

Development Costs

Development projects and the related carrying costs, including interest, property taxes, insurance and allocated direct development salary cost during the construction period, are capitalized and reported in the accompanying Consolidated Balance Sheets as "Development and capital improvements in progress" during the construction period. Interest is capitalized in accordance with accounting standards governing the capitalization of interest. Upon completion and certification for occupancy of individual buildings or floors within a development, amounts representing the completed portion of total estimated development costs for the project are transferred to "Land" and "Buildings and improvements and other" as real estate held for investment. Capitalization of interest, property taxes, insurance and allocated direct development salary costs cease upon the transfer. The assets are depreciated over their estimated useful lives. Total capitalized costs (including capitalized interest, salaries and real estate taxes) during the years ended December 31,2017, 2016 and 2015 was approximately $11.0 million, $2.7 million and $2.3 million, respectively. Certain costs associated with the lease-up of development projects, including cost of model units, furnishings, signs and grand openings, are capitalized and amortized over their respective estimated useful lives. All other costs relating to renting development projects are expensed as incurred.

Acquisition of Real Estate Assets

The Company adopted ASU 2017-01, Clarifying the Definition of a Business (Topic 805), effective January 1, 2017. Subsequent to the adoption of ASU 2017-01, most acquisitions of operating properties qualify as asset acquisitions rather than business combinations. Accordingly, the cost of the real estate acquired is allocated to the acquired tangible assets, consisting of land, buildings and improvements and other, and identified intangible assets, consisting of the value of in-place leases and other contracts, on a relative fair value basis.

The purchase price of an acquired property is allocated based on the relative fair value of the individual components as a proportion of the total assets acquired. The Company allocates the cost of the tangible assets of an acquired property by valuing the building as if it were vacant, based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a building using methods similar to those used by independent appraisers. These methods include using stabilized net operating income, or NOI, and market specific capitalization and discount rates. In allocating the cost of identified intangible assets of an acquired property, the in-place leases are valued based on current rent rates and time and cost to lease a unit. Management concluded that the residential leases acquired in connection with each of its property acquisitions approximate at-market rates since the residential lease terms generally do not extend beyond one year.

For residential leases, the fair value of the in-place leases and resident relationships is amortized over 6 months, which represents the estimated remaining term of the tenant leases. For commercial leases, the fair value of in-place leases and resident relationships is amortized over the remaining term of the commercial leases. The amount of these lease intangibles included in "Other assets" totaled $11.2 million and $42.4 million as of December 31, 2017, and 2016, respectively. Accumulated amortization for these leases totaled $4.1 million and $7.3 million as of December 31, 2017 and 2016, respectively. The amortization of these intangibles recorded as "Depreciation and amortization expense" was $29.4 million, $8.7 million, and $5.0 million for the years ended December 31, 2017, 2016, and 2015, respectively. The estimated aggregate future amortization expense of in-place leases is approximately $2.8 million, $1.6 million, $0.8 million, $0.5 million, and $0.3 million for the years ended December 31, 2018, 2019, 2020, 2021, and 2022, respectively.

F-17

As a result of the adoption of ASU 2017-01, the Company believes most acquisitions of operating properties will qualify as asset acquisitions and associated transaction costs will be capitalized. Acquisition costs include appraisal fees, title fees, broker fees, and other legal costs to acquire the property. For the year ended December 31, 2017, acquisition costs totaling $1.3 million related to the Company's acquisitions of Charlotte at Midtown and Acklen West End were capitalized and allocated to the assets based on the relative fair market value of those underlying assets; see Note 15 for additional information on 2017 acquisitions. For the accounting policy on larger, portfolio style acquisitions which qualify as business combinations (rather than asset acquisitions), see Note 2.

Impairment of Long-lived Assets

The Company accounts for long-lived assets in accordance with the provisions of accounting standards for the impairment or disposal of long-lived assets. Management periodically evaluates long-lived assets, including investments in real estate, for indicators that would suggest that the carrying amount of the assets may not be recoverable. The judgments regarding the existence of such indicators are based on factors such as operating performance, market conditions and legal factors. Long-lived assets, such as real estate assets, equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the Consolidated Balance Sheets and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group or a property classified as held for sale are presented separately in the appropriate asset and liability sections of the Consolidated Balance Sheets.

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. 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 may 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 expected ultimately 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. See Note 12 for additional information on loss contingencies.

Undeveloped Land

Undeveloped land includes sites intended for future multifamily developments, sites for future commercial development and sites intended for residential use, which are carried at the lower of cost or fair value in accordance with GAAP and any costs incurred prior to commencement of pre-development activities are expensed as incurred.

Investment in Unconsolidated Affiliates

Immediately prior to the effective date of the Merger, Post Properties was an investor, together with other institutional investors, in a limited liability company, or the Apartment LLC, that indirectly owned one apartment community, Post

F-18

Massachusetts Avenue, located in Washington, D.C.  Post Properties owned a 35.0% equity interest in the unconsolidated joint venture, which was retained by MAA immediately following the close of the Merger and as of December 31, 2017. The Company provides property and asset management services to the Apartment LLC for which it earns fees. The joint venture was determined to be a VIE, but the Company is not designated as a primary beneficiary. As a result, the Company accounts for its investment in the Apartment LLC using the equity method of accounting as the Company is able to exert significant influence over the joint venture but does not have a controlling interest. At December 31, 2017, the Company's investment in the Apartment LLC totaled $45.0 million.  

During September 2017, a subsidiary of the Operating Partnership entered into a limited partnership together with a general partner and other limited partners to form Real Estate Technology Ventures, L.P. The Operating Partnership indirectly owns 31.0% of the limited partnership. The limited partnership was determined to be a VIE, but the Company is not designated as a primary beneficiary. As a result, the Company accounts for its investment in the limited partnership using the equity method of accounting as the investment is considered more than minor. At December 31, 2017, the Company's investment in the limited partnership totaled $1.5 million. The Company is committed to make additional capital contributions totaling $13.5 million if and when called by the general partner of the limited partnership prior to September 2022.

Investment in Consolidated Real Estate Joint Venture

In 2015, Post Properties entered into a joint venture arrangement with a private real estate company to develop, construct and operate a 359-unit apartment community in Denver, Colorado. At December 31, 2017, the Company owned a 92.5% equity interest in the consolidated joint venture. In 2015, the joint venture acquired the land site and initiated the development of the apartment community. The venture partner will generally be responsible for the development and construction of the community and the Company will continue to manage the community upon its completion. The joint venture was determined to be a VIE with the Company designated as the primary beneficiary. As a result, the accounts of the joint venture are consolidated by the Company. At December 31, 2017, the consolidated assets, liabilities and equity included construction in progress of $36.9 million; buildings and improvements and other of $33.9 million; land of $14.9 million; and accrued expenses and other liabilities of $6.5 million.

Cash and Cash Equivalents

Investments in money market accounts and certificates of deposit with original maturities of three months or less are considered to be cash equivalents.

Restricted Cash

Restricted cash consists of security deposits required to be held separately, escrow deposits held by lenders for property taxes, insurance, debt service, and replacement reserves, and exchanges under Section 1031(b) of the Internal Revenue Code of 1986, as amended, or the Code. Section 1031(b) exchanges are treated as investing activities in the Consolidated Statements of Cash Flows.

Other Assets

Other assets consist primarily of receivables and deposits from residents, the value of derivative contracts, deferred rental concessions, deferred financing costs relating to lines of credit, and other prepaid expenses. Also included in other assets are the fair market value of in-place leases and resident relationships, net of accumulated amortization.

Accrued Expenses and Other Liabilities

Accrued expenses consist of accrued dividends payable, accrued real estate taxes, accrued interest payable, accrued loss contingencies, accounts payable, fair market value of interest rate swaps (see Note 7), security deposits not related to restricted cash, other accrued expenses, and unearned income. Significant accruals include accrued dividends payable of $108.7 million and $102.4 million at December 31, 2017 and 2016, respectively; accrued real estate taxes of $99.6 million and $97.6 million at December 31, 2017 and 2016, respectively; unearned income of $40.8 million and $39.4 million at December 31, 2017 and 2016, respectively; accrued loss contingencies of $32.1 million and $42.1 million at December 31, 2017 and 2016, respectively; security deposits of $19.1 million and $18.8 million at December 31, 2017 and 2016, respectively; and accrued interest payable of $18.1 million and $19.1 million at December 31, 2017 and 2016, respectively.

F-19

Self-Insurance

The Company is self-insured for workers' compensation claims up to $500,000 and for general liability claims up to $100,000. The Company accrues for expected liabilities less than these amounts based on third party actuarial estimates of ultimate losses. Claims exceeding these amounts are insured by a third party.

Income Taxes

MAA has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, or the Code, and intends to continue to operate in such a manner. The current and continuing qualification as a REIT depends on MAA's ability to meet the various requirements imposed by the Code, which are related to organizational structure, distribution levels, diversity of stock ownership and certain requirements with respect to the nature and diversity of MAA’s assets and sources of MAA’s gross income. As long as MAA qualifies for taxation as a REIT, it will generally not be subject to United States federal corporate income tax on its taxable income that is currently distributed to shareholders. This treatment substantially eliminates the "double taxation" (i.e., income taxation at both the corporate and shareholder levels) that generally results from an investment in a corporation. Even if MAA qualifies as a REIT, MAA may be subject to United States federal income and excise taxes in certain situations, such as if MAA fails to distribute timely all of its taxable income with respect to a taxable year. MAA also will be required to pay a 100% tax on any net income on non-arm’s length transactions between MAA and one of its taxable REIT subsidiaries, or TRS. In addition, MAA could be subject to the alternative minimum tax. Furthermore, MAA and its shareholders may be subject to state or local taxation in various state or local jurisdictions, including those in which MAA transacts business or its shareholders reside, and the applicable state and local tax laws may not conform to the United States federal income tax treatment. Any taxes imposed on MAA would reduce its operating cash flow and net income.

Certain of the Company's operations and activities, including asset management and risk management, are conducted through TRSs, which are subject to United States federal corporate income tax without the benefit of the dividends paid deduction applicable to REITs. MAA accounts for deferred taxes of a TRS by recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that all or some portion of the deferred tax assets will not be realized. Based on this evaluation, at December 31, 2017, net of the valuation allowance, the net deferred tax assets were reduced to zero. MAA recognizes liabilities for uncertain income tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires MAA to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. MAA classifies interest related to income tax liabilities, and if applicable, penalties, as a component of income tax expense. As of December 31, 2017, MAA did not have any unrecognized tax benefits, and MAA does not believe that there will be any material changes in its unrecognized tax positions over the next 12 months. "Income tax expense" reflected in the Consolidated Statements of Operations represents the Texas-based margin tax for all Texas properties and state taxes for a TRS.

Derivative Financial Instruments

The Company utilizes certain derivative financial instruments, primarily interest rate swaps and interest rate caps, during the normal course of business to manage, or hedge, the interest rate risk associated with our variable rate debt or as hedges in anticipation of future debt transactions to manage well-defined interest rate risk associated with the transaction.

Additionally, the 867,846 shares of MAA's Series I preferred stock issued as consideration in the Merger are redeemable, at the Company's option, beginning on October 1, 2026, at the redemption price of $50 per share (see Note 9). The redemption feature embedded in the preferred stock was evaluated in accordance with ASC 815, Derivatives and Hedging, and the Company determined that it was required to bifurcate the value associated with the redemption feature from the host instrument, the perpetual preferred shares. The redemption feature embedded in the MAA Series I preferred stock is reported as a derivative asset in "Other assets" in the accompanying Consolidated Balance Sheets at its fair value and will be adjusted to its fair value at each reporting date, with a corresponding adjustment to "Other non-operating income (expense)". See Note 7 for further discussion on derivatives and the fair value of financial instruments.

Fair Value Measurements

The Company applies the guidance in ASC Topic 820, Fair Value Measurements and Disclosures, to the valuation of real estate

F-20

assets recorded at fair value, if any; 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 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.

Assets Held for Sale

As of December 31, 2017, one land parcel was classified as held for sale. The criteria for classifying the land parcel as held for sale were met during June 2017; however, the sale is not expected to close until the first quarter of 2018. As a result, the assets associated with the land parcel were presented as held for sale in the accompanying Consolidated Balance Sheets.

Recent Accounting Pronouncements

The following table provides a brief description of recent accounting pronouncements that could have a material effect on the Company's consolidated financial statements:

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
ASU 2014-09, Revenue from Contracts with Customers	The ASU establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services as outlined in a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied. Income from lease contracts is specifically excluded from this ASU.	The ASU is effective for annual reporting periods beginning after December 15, 2017 Early adoption is permitted.	The amendments may be applied using the full retrospective transition method or by using the modified retrospective transition method with a cumulative effect recognized as of the date of initial application. The Company adopted ASU 2014-09 effective January 1, 2018, using the modified retrospective approach. The majority of the Company's revenue is derived from real estate lease contracts, which falls outside the scope of the ASU. The Company has completed its analysis of non-lease related revenues. The adoption of the ASU does not have a material impact on the Company's consolidated financial statements or to the Company's internal accounting policies. The guidance does require additional disclosures regarding the nature and timing of the Company's revenue transactions upon adoption.
ASU 2016-02, Leases	The ASU amends existing accounting standards for lease accounting and establishes the principles for lease accounting for both the lessee and lessor. The amendment requires an entity to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendment also requires certain quantitative and qualitative disclosures about leasing arrangements.	The ASU is effective for annual reporting periods beginning after December 15, 2018; however, early adoption is permitted.	The standard must be adopted using a modified retrospective transition and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. Management is currently evaluating the impact the standard will have on the consolidated financial statements and related disclosures upon adoption. The Company plans to adopt the ASU effective January 1, 2019.

F-21

ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)	The ASU clarifies how several specific cash receipts and cash payments are to be presented and classified on the statement of cash flows, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration made after a business combination, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of predominance principle.	The ASU is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted.	Each amendment in this standard must be applied prospectively, retrospectively, or as of the beginning of the earliest comparative period presented in the year of adoption, depending on the type of amendment. The Company adopted ASU 2016-15 as of January 1, 2018. Management has determined three of the eight transactions in the update are relevant to MAA and its cash flows, including: 1) debt prepayment or debt extinguishment costs, 2) proceeds from the settlement of insurance claims and 3) distributions received from equity method investees. Management performed an analysis and determined only the change in classification of debt prepayment or debt extinguishment costs, which is currently reported in operating activities, will have a significant impact on the consolidated statements of cash flows. Upon adoption in the first quarter of 2018, $1.7 million of cash outflows for debt prepayment or extinguishment costs currently reported in net cash provided by operating activities for the year ended December 31, 2017, will be re-classified to and reported in net cash used in financing activities.
ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (A Consensus of the FASB Emerging Issues Task Force)	The ASU requires restricted cash to be presented with cash and cash equivalents when reconciling the beginning and ending amounts in the consolidated statements of cash flows.	The ASU is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted.	The update should be applied retrospectively to each period presented. The Company adopted ASU 2016-18 as of January 1, 2018. The Company currently reports the change in restricted cash within the operating and investing activities in the consolidated statements of cash flows. Upon adoption in the first quarter of 2018, cash and cash equivalents reported in the consolidated statements of cash flows for the year ended December 31, 2017 will increase by approximately $78.1 million to reflect the restricted cash balances. Additionally, net cash used in investing activities will decrease by $10.6 million for the year ended December 31, 2017.
ASU 2017-12, Derivatives and Hedging (Topic 815)	The ASU clarifies hedge accounting requirements, improves disclosure of hedging arrangements, and better aligns risk management activities and financial reporting for hedging relationships.	The ASU is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted.	The standard should be adopted using a modified retrospective approach. This adoption method will require the Company to recognize the cumulative effect of initially applying ASU 2017-12 as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings. The Company elected to early adopt the ASU as of January 1, 2018. Management has completed its assessment of the impact the standard has on the Company's consolidated financial statements and related disclosures. Adoption of the ASU does not have a material impact on the consolidated financial statements or the Company's internal accounting policies.

2.     BUSINESS COMBINATIONS

Merger of MAA and Post Properties

The Company completed the Merger on December 1, 2016. As part of the Merger, the Company acquired 61 wholly-owned apartment communities encompassing 24,138 units, including 269 apartment units in one community held in an unconsolidated entity, and 2,262 apartment units in six communities that were under development at the date of the Merger. Post Properties had operations in ten markets across the United States. In addition to the apartment communities, the Company also acquired four commercial properties, totaling approximately 232,000 square feet of combined gross leasable area. The consolidated net assets and results of operations of Post Properties are included in the Company's consolidated financial statements from the closing date going forward.

The total purchase price of approximately $4.0 billion was determined based on the number of shares of Post Properties' common stock, the number of shares of Post Properties’ Series A preferred stock, and the number of shares of Post LP's Class A Units of limited partnership interest outstanding as of December 1, 2016, in addition to cash consideration provided by the Operating Partnership immediately prior to the Merger to retire a $300.0 million unsecured term loan and a $162.0 million line of credit. In all cases in which MAA’s common stock price was a determining factor in arriving at final consideration for the Merger, the stock price used to determine the purchase price was the opening price of MAA’s common stock on December 1,

F-22

2016 ($91.41 per share). At the date of acquisition, the MAA Series I preferred stock consideration was valued at $77 per share, which included a $14.24 per share bifurcated call option (See Notes 7 and 9).The total purchase price also included $2.0 million of other consideration, a majority of which related to assumed stock compensation plans. As a result of the Merger, the Company issued approximately 38.0 million shares of MAA common stock, approximately 80,000 OP units, and 867,846 newly issued shares of MAA’s Series I preferred stock.

The Merger has been accounted for using the acquisition method of accounting in accordance with ASC 805, Business Combinations, which requires, among other things, that the assets acquired and liabilities assumed be recognized at their acquisition date fair values.

For larger, portfolio style acquisitions, such as the Merger, management engages a third party valuation specialist to assist with the fair value assessment, which includes an allocation of the purchase price. Similar to management's methods, the third party generally uses cash flow analysis as well as an income approach and a market approach to determine the fair value of assets acquired. The third party specialist uses stabilized NOI and market specific capitalization and discount rates. Management reviews the inputs used by the third party specialist as well as the allocation of the purchase price provided by the third party specialist to ensure reasonableness and the procedures are performed in accordance with management's policies.

The allocation of the purchase price valuation described above required a significant amount of judgment and represents management's best estimate of the fair value as of the acquisition date. The following final purchase price allocation for the Merger was based on the Company's valuation as well as estimates and assumptions of the acquisition date fair value of the tangible and intangible assets acquired and liabilities assumed.

The following table summarizes the final purchase price allocation as of the date of the Merger (in thousands):

	December 1, 2016
Land	$	874,616
Buildings and improvements and other	3,479,483
Development and capital improvements in progress	183,881
Undeveloped land	24,200
Investment in real estate joint venture	44,435
Cash and cash equivalents	34,292
Restricted cash	3,608
Other assets	94,899
Total assets acquired	4,739,414
Notes payable	(595,609)
Accrued expenses and other liabilities	(132,906)
Total liabilities assumed, including debt	(728,515		)
Noncontrolling interests - consolidated real estate entity	(2,306		)
Total purchase price	$	4,008,593

The allocation of fair values of the assets acquired and liabilities assumed changed from the allocation reported in Note 2 to the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2016, filed with the SEC on February 24, 2017. The changes were based on information concerning the subject assets and liabilities that was not yet known at the time of the filing of the Annual Report on Form 10-K for the year ended December 31, 2016. Specifically, the purchase price allocation was updated primarily due to an adjustment to litigation reserves offset by an increase in the derivative asset value of the preferred share bifurcated call option (included in "Other assets") and real estate values.

The Company incurred total merger and integration related expenses of $20.0 million and $40.8 million for the years ended December 31, 2017and2016, respectively. The amounts were expensed as incurred and are included in the Consolidated Statements of Operations in "Merger and integration expenses". Merger related expenses primarily consisted of severance and professional costs, and integration related expenses primarily consisted of temporary systems, staffing, and facilities costs.

3.    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 years ended December 31, 2017, 2016, and 2015, MAA's basic earnings per share is computed using the two-class method, as the two-class method is the more dilutive calculation, and is presented below (dollars and shares in thousands, except per share amounts):

4.    EARNINGS PER OP UNIT OF MAALP

Basic earnings per OP 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 OP Unit. Diluted earnings per OP Unit reflects the potential dilution that could occur if securities or other contracts to issue OP Units were exercised or converted into OP Units. A reconciliation of the numerators and denominators of the basic and diluted earnings per OP Unit computations for the years ended December 31, 2017, 2016, and 2015 is presented below (dollars and units in thousands, except per unit amounts):

5.STOCK BASED COMPENSATION

Overview

MAA accounts for its stock based employee compensation plans in accordance with accounting standards governing stock based compensation. These standards require an entity to measure the cost of employee services received in exchange for an award of an equity instrument based on the award's fair value on the grant date and recognize the cost over the period during which the employee is required to provide service in exchange for the award, which is generally the vesting period. Any liability awards issued are remeasured at each reporting period.

MAA’s stock compensation plans consist of a number of incentives provided to attract and retain independent directors, executive officers and key employees. Incentives are currently granted under the Amended and Restated 2013 Stock Incentive Plan, or the Stock Plan, which was approved at the 2014 annual meeting of MAA shareholders. The Stock Plan allows for the grant of restricted stock and stock options up to 625,000 shares. MAA believes that such awards better align the interests of its employees with those of its shareholders.

Compensation expense is generally recognized for service based restricted stock awards using the straight-line method over the vesting period of the shares regardless of cliff or ratable vesting distinctions. Compensation expense for market and

F-25

performance based restricted stock awards is generally recognized using the accelerated amortization method with each vesting tranche valued as a separate award, with a separate vesting date, consistent with the estimated value of the award at each period end. Additionally, compensation expense is adjusted for actual forfeitures for all awards in the period that the award was forfeited. Compensation expense for stock options is generally recognized on a straight-line basis over the requisite service period. MAA presents stock compensation expense in the Consolidated Statements of Operations in "General and administrative expenses". Effective January 1, 2017, the Company adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which allows employers to make a policy election to account for forfeitures as they occur. The Company elected this option using the modified retrospective transition method, with a cumulative effect adjustment to retained earnings, and there was no material effect on the consolidated financial position or results of operations taken as a whole resulting from the reversal of previously estimated forfeitures.

Total compensation expense under the Stock Plan was approximately $10.8 million, $12.2 million and $6.9 million for the years ended December 31, 2017, 2016 and 2015, respectively. Of these amounts, total compensation expense capitalized was approximately $0.2 million, $0.7 million and $0.7 million for the years ended December 31, 2017, 2016 and 2015, respectively. As of December 31, 2017, the total unrecognized compensation expense was approximately $14.1 million. This cost is expected to be recognized over the remaining weighted average period of 1.2 years. Total cash paid for the settlement of plan shares totaled $4.8 million, $2.0 million and $1.0 million for the years ended December 31, 2017, 2016 and 2015, respectively. Information concerning grants under the Stock Plan is listed below.

Restricted Stock

In general, restricted stock is earned based on either a service condition, performance condition, or market condition, or a combination thereof, and generally vests ratably over a period from 1 year to 5 years. Service based awards are earned when the employee remains employed over the requisite service period and are valued on the grant date based upon the market price of MAA common stock on the date of grant. Market based awards are earned when MAA reaches a specified stock price or specified return on the stock price (price appreciation plus dividends) and are valued on the grant date using a Monte Carlo simulation. Performance based awards are earned when MAA reaches certain operational goals such as funds from operations, or FFO, targets and are valued based upon the market price of MAA common stock on the date of grant as well as the probability of reaching the stated targets. MAA remeasures the fair value of the performance based awards each balance sheet date with adjustments made on a cumulative basis until the award is settled and the final compensation is known. The weighted average grant date fair value per share of restricted stock awards granted during the years ended December 31, 2017, 2016 and 2015, was $84.53, $73.20 and $68.35, respectively.

The following is a summary of the key assumptions used in the valuation calculations for market based awards granted during the years ended December 31, 2017, 2016 and 2015:

	2017	2016	2015
Risk free rate	0.65% - 1.57%	0.49% - 1.27%	0.10% - 1.05%
Dividend yield	3.573%	3.634%	3.932%
Volatility	20.43% - 21.85%	18.41% - 19.45%	15.41% - 16.04%
Requisite service period	3 years	3 years	3 years

The risk free rate was based on a zero coupon risk-free rate. The minimum risk free rate was based on a period of 0.25 years for the years ended December 31, 2017, 2016 and 2015. The maximum risk free rate was based on a period of 3 years for the years ended December 31, 2017, 2016 and 2015. The dividend yield was based on the closing stock price of MAA stock on the date of grant. Volatility for MAA was obtained by using a blend of both historical and implied volatility calculations. Historical volatility was based on the standard deviation of daily total continuous returns, and implied volatility was based on the trailing month average of daily implied volatilities interpolating between the volatilities implied by stock call option contracts that were closest to the terms shown and closest to the money. The minimum volatility was based on a period of 3 years, 2 years and 1 year for the years ended December 31, 2017, 2016 and 2015, respectively. The maximum volatility was based on a period of 1 year, 1 year and 2 years for the years ended December 31, 2017, 2016 and 2015, respectively. The requisite service period is based on the criteria for the separate programs according to the vesting schedule.

The total fair value of shares vested during the years ended December 31, 2017, 2016 and 2015 was approximately $10.5 million, $5.1 million and $2.9 million, respectively.

Stock Options

Stock options are earned when the employee remains employed over the requisite service period and vest ratably over a period from 0.3 years to 2.3 years. Stock options exercised result in new common shares being issued on the open market by the Company. The fair value of stock option awards is determined using the Black-Scholes or Monte Carlo valuation models. No stock options were granted during the years ended December 31, 2017 or December 31, 2015. During the year ended December 31, 2016, 108,198 fully vested stock options were granted with a weighted average grant date fair value of $18.08 per option as a result of options exchanged during the Merger.

The following is a summary of the key assumptions used in the Monte Carlo valuation calculations for stock options granted during the year ended December 31, 2016:

	2016
Risk free rate	0.64% - 2.63%
Dividend yield	3.81%
Volatility	21.02% - 21.57%
Expected term	1.11 - 2.11 years

The U.S. Treasury bill rate was used to represent the risk-free rate based on the expected life of the option. The current dividend yield at the time of grant was used to estimate the dividend yield over the life of the option. Volatility is based on the actual changes in the market value of MAA’s stock and is calculated using daily market value changes from the date of grant over a past period equal to the expected term of the stock options. The expected term represents an estimate of the period of time options are expected to remain outstanding.

A summary of the status of the stock options as of December 31, 2017 and the changes for the year ended December 31, 2017 is presented below:

Stock Options	Options		Weighted Average Exercise Price
Outstanding at January 1, 2017	147,282		$	76.16
Granted	—		—
Exercised	(21,006	)	64.92
Expired	(17,838	)	109.05
Outstanding at December 31, 2017	108,438		$	72.93

All options outstanding at December 31, 2017 were exercisable and had an intrinsic value of $3.0 million with a weighted average remaining term of 6.0 years. There were 21,006 options and 7,342 options exercised during the years ended December 31, 2017 and 2015, respectively. Cash received from the exercise of stock options totaled $0.4 million for both the years ended December 31, 2017 and 2015, respectively. During the year ended December 31, 2016, no cash was received from the exercise of stock options as no options were exercised.

Unsecured Revolving Credit Facility

The Company maintains a $1.0 billion unsecured credit facility with a syndicate of banks led by KeyBank National Association, or the KeyBank Facility. The KeyBank Facility includes an expansion option up to $1.5 billion. The KeyBank Facility bears an interest rate of the London Interbank Offered Rate, or LIBOR, plus a spread of 0.85% to 1.55% based on an investment grade pricing grid and is currently bearing interest at 2.47%. The KeyBank Facility expires in April 2020 with an option to extend for an additional six months. At December 31, 2017, the Company had $410.0 million outstanding under the facility with another approximate $2.5 million of additional capacity used to support outstanding letters of credit. During the year ended December 31, 2017, the facility balance decreased by $80.0 million as result of $885.0 million in payments to the facility offset by $805.0 million in proceeds from the facility.

Senior Unsecured Notes

As of December 31, 2017, the Company had approximately $2.0 billion in principal amount of publicly issued senior unsecured notes and $292.0 million of privately placed senior unsecured notes. These senior unsecured notes had maturities at issuance ranging from seven to twelve years, averaging 6.9 years remaining until maturity as of December 31, 2017.

In May 2017, the Operating Partnership publicly issued $600.0 million in aggregate principal amount of notes, maturing on June 1, 2027 with an interest rate of 3.60% per annum, or the 2027 Notes. The purchase price paid by the initial purchasers was 99.58% of the principal amount. The 2027 Notes are general unsecured senior obligations of the Operating Partnership and rank equally in right of payment with all other senior unsecured indebtedness of the Operating Partnership. Interest on the 2027 Notes is payable on June 1 and December 1 of each year, beginning on December 1, 2017. The net proceeds from the offering, after deducting the original issue discount of approximately $2.5 million and underwriting commissions and expenses of approximately $3.9 million, were approximately $593.6 million. The 2027 Notes have been reflected net of discount and debt issuance costs in the Consolidated Balance Sheets. In connection with the issuance of the 2027 Notes, the Operating Partnership cash settled $300 million in forward interest rate swap agreements. After considering the forward interest rate swaps, the effective interest rate of the 2027 Notes was 3.68% over the ten year term.

In July 2017, the Company retired $150.0 million of senior unsecured notes that had been assumed as part of the Merger. The notes were scheduled to mature in October 2017.

In November 2017, the Company retired $18.0 million of privately placed senior unsecured notes at maturity.

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 at December 31, 2017 and December 31, 2016, totaled $3.2 billion and $3.0 billion, respectively, and had estimated fair values of $3.3 billion and $3.1 billion (excluding prepayment penalties), respectively, as of December 31,

F-30

2017 and December 31, 2016. The carrying value of variable rate notes payable (excluding the effect of interest rate swap and cap agreements) at December 31, 2017 and December 31, 2016, totaled $1.3 billion and $1.5 billion, respectively, and had estimated fair values of $1.3 billion and $1.5 billion (excluding prepayment penalties), respectively, as of December 31, 2017 and December 31, 2016. 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 that these rates reasonably estimate current market rates. Management has determined the inputs used to value the outstanding debt fall within Level 2 of the fair value hierarchy, and therefore, the fair market valuation of debt is considered Level 2 in the fair value hierarchy.

Financial Instruments Measured at Fair Value on a Recurring Basis

The Company uses interest rate swaps and interest rate caps to add stability to interest expense and to manage its exposure to interest rate movements. 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.

The fair values of interest rate options are determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rise above the strike rate of the caps. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. The fair value of interest rate derivative contracts designated as hedging instruments recorded in "Other assets" in the accompanying Consolidated Balance Sheets was $3.6 million and $2.4 million as of December 31, 2017 and December 31, 2016, respectively. The fair value of interest rate derivative contract liabilities recorded in "Accrued expenses and other liabilities" in the accompanying Consolidated Balance Sheets was $1.3 million and $7.6 million as of December 31, 2017 and December 31, 2016, respectively.

To comply with the provisions of ASC 820, 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 has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Based on the fair value measurement guidance issued by the Financial Accounting Standard Board, 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.

The derivative asset related to the redemption feature embedded in the MAA Series I preferred stock issued in connection with Merger 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 share assuming the call option is exercised, with the value of the bifurcated call option as the difference between the two values. This 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 per share (see Note 9). The analysis uses observable market-based inputs, 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 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 or expense" in the accompanying Consolidated Statements of Operations. The embedded derivative for these preferred shares was initially recorded at a fair value of $10.8 million at the date of the Merger and as of December 31, 2016 and then subsequently adjusted to its fair value of $21.2 million at December 31, 2017. The $10.4 million increase includes a purchase price allocation adjustment of $1.6 million, which is included in the Merger's opening balance sheet, and was recorded in the first quarter of 2017, as well as $8.8 million of mark to market adjustments of non-cash income recorded to reflect the change in fair value of the derivative asset in the year ended December 31, 2017.

The Company has determined the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, and as a result, all of its derivatives held as of December 31, 2017 and December 31, 2016 were classified as Level 2 in the fair value hierarchy.

F-31

Cash Flow Hedges of Interest Rate Risk

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings and is mainly attributable to a mismatch in the underlying indices of the derivatives and the hedged interest payments made on the variable rate debt and due to the designation of acquired interest rate swaps with a non-zero fair value at inception.

Amounts reported in "Accumulated other comprehensive income" related to derivatives designated as qualifying cash flow hedges will be 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 $0.9 millionwill 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.

As of December 31, 2017, the Company had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk:

Interest Rate Derivative	Number of Instruments	Notional
Interest rate cap	1	$25,000,000
Interest rate swaps	10	$550,000,000

Tabular Disclosure of the Effect of Derivative Instruments on the Statements of Operations

Credit-risk-related Contingent Features

Certain of the Company's derivative contracts contain a provision where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company's default on the indebtedness. As of December 31, 2017, the Company had not breached the provisions of these agreements. If the provisions had been breached, the Company could have been required to settle its obligations under the agreements at the termination value of $1.6 million.

Although the Company's derivative contracts are subject to master netting arrangements, which serve as credit mitigants to both the Company and its counterparties under certain situations, the Company does not net its derivative fair values or any existing rights or obligations to cash collateral in the Consolidated Balance Sheets.

F-32

Other Comprehensive Income

The Company's other comprehensive income consists entirely of gains and losses attributable to the effective portion of its cash flow hedges. The chart below reflects the change in the balance for the years ended December 31, 2017, 2016, and 2015 (in thousands):

8.    INCOME TAXES

Due to the structure of MAA as a REIT and the nature of the operations of its operating properties, no provision for federal income taxes has been made at the MAA level. In addition, as MAALP is structured as a limited partnership, and its partners recognize their proportionate share of income or loss in their tax returns, no provision for federal income taxes has been made at the MAALP level. Historically, the Company has incurred certain state and local income, excise and franchise taxes. The Company has elected TRS status for certain of its corporate subsidiaries. As a result, the TRSs incur both federal and state income taxes on any taxable income after consideration of any net operating losses.

Taxable REIT Subsidiaries

The Company acquired the operations of a TRS, Colonial Properties Services, Inc., or CPSI, through an acquisition in 2013. As a result, CPSI’s tax attributes were included in MAA’s consolidated financial statements subsequent to the acquisition date. CPSI has provided property development, construction, leasing and management services for joint venture and third-party owned properties, administrative services to MAA and engaged in for-sale development activity. CPSI also owned and operated two multifamily apartment communities; however, during 2016, CPSI distributed these communities to MAALP.  The distribution resulted in a reduction of the deferred tax asset for real estate asset basis differences and the valuation allowance. In 2017, CPSI converted from a corporation to a limited liability company, which resulted in a deemed liquidation for income tax purposes. At the date of conversion, CPSI changed its name to CPSI, LLC and is no longer a TRS. CPSI, LLC is currently a disregarded entity for income tax purposes, is solely owned by MAALP and owns undeveloped land.

The Company acquired the operations of a TRS, Post Asset Management, Inc., or PAM, through the Merger in 2016. As a result, PAM’s tax attributes are included in MAA’s consolidated financial statements subsequent to the acquisition date. PAM provides third-party services to MAA and MAA’s indirectly owned properties. PAM also owns a tract of undeveloped land.

The Company generally reimburses its TRSs for payroll and other costs incurred in providing services to MAA. All intercompany transactions are eliminated in the accompanying consolidated financial statements. A TRS is an entity that is subject to federal, state and any applicable local corporate income tax without the benefit of the dividends paid deduction applicable to REITs. The Company’s TRSs did not generate any material taxable income or income tax expense for the years ended December 31, 2017, 2016 and 2015.

The TRSs use the liability method of accounting for income taxes. Deferred income tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.

As a result of the CPSI conversion to CPSI, LLC and deemed liquidation, the Company’s deferred tax asset and liability balances as of December 31, 2017 were immaterial. As of December 31, 2016, the Company had recorded net deferred tax

F-33

assets relating to CPSI, which included a net operating loss, or NOL, of $58.2 million. The net deferred tax assets were fully offset by a valuation allowance as it was more likely than not the net deferred tax assets would not be realized.

For the years ended December 31, 2017 and 2016, the components of the Company’s deferred income tax assets and liabilities were as follows (in thousands):

	December 31, 2017		December 31, 2016

The Company had no reserve for uncertain tax positions for the years ended December 31, 2017, 2016 and 2015. If necessary, the Company accrues interest and penalties on unrecognized tax benefits as a component of income tax expense. For the years ended December 31, 2017, 2016 and 2015, other expenses include estimated state franchise and other taxes, including franchise taxes in North Carolina and Tennessee. The income tax expense line item shown in the Consolidated Statements of Operations represents the Texas-based margin tax for all Texas properties and federal and state taxes for PAM.

As of December 31, 2017 and 2016, the Company held federal NOL carryforwards of approximately $71.5 million for income tax purposes that expire in years 2019 to 2033. During the year ended December 31, 2016, the Company's NOL increased by $25.2 million through its acquisition of Post Properties. Utilization of any NOL carryforwards is subject to an annual limitation due to ownership change limitations provided by Section 382 of the Code and similar state provisions. The annual limitations may result in the expiration of NOL carryforwards before utilization. The Company may use these NOLs to offset all or a portion of the taxable income generated at the REIT level.

Tax years 2014 through 2017 are subject to examination by the Internal Revenue Service. No tax examination is currently in process.

F-34

For income tax purposes, dividends paid to holders of common stock primarily consist of ordinary income, return of capital, capital gains, qualified dividends and un-recaptured Section 1250 gains, or a combination thereof. For the years ended December 31, 2017, 2016 and 2015, dividends per share held for the entire year were estimated to be taxable as follows:

	2017				2016				2015

The Company designated the per share amounts above as capital gain dividends in accordance with the requirements of the Code. The difference between net income available to common shareholders for financial reporting purposes and taxable income before dividend deductions relates primarily to temporary differences such as depreciation and amortization and taxable gains on sold properties in 2017.

Merger

As discussed in Note 2, on December 1, 2016, the Company completed the Merger, whereby Post Properties merged with and into MAA completing the Parent Merger and Post LP merged with and into MAALP completing the Partnership Merger. The Company believes the Parent Merger constituted a tax free merger under Code Section 368(a). Additionally, the Company believes the Partnership Merger constituted a tax free merger under Code Section 708. As a result of the tax free merger treatment, the Merger did not result in the recognition of a gain to any security holder of MAA, Post Properties, MAALP or Post LP.

U.S. Tax Reform

In December 2017, the Tax Cuts and Jobs Act, or the Act, was enacted in the United States, requiring companies to account in 2017 for the current and future effects of the legislative changes. As REITs are pass-through entities for the purpose of U.S. federal taxation, the legislative changes created by the Act are largely not applicable to the Company. Generally, the effects to REITs resulting from the Act include a reduction in the TRS federal statutory tax rate to 21% and a one-time inclusion in REIT taxable income of foreign subsidiary earnings. As noted above, the TRS’s recognized no material taxable income in 2017 and the Company has no foreign subsidiaries. Management has concluded there was no material effect to the Company’s consolidated financial statements from either a tax or financial statement perspective as a result of the Act.

9.    SHAREHOLDERS' EQUITY OF MAA

On December 31, 2017, 113,643,166 shares of common stock of MAA and 4,191,586 OP Units (excluding the OP Units held by MAA) were issued and outstanding, representing a total of 117,834,752 shares and units. At December 31, 2016, 113,518,212 shares of common stock of MAA and 4,220,403 OP units were outstanding, representing a total of 117,738,615 shares and units. Options to purchase 108,438 shares of MAA's common stock were outstanding as of December 31, 2017 compared to 147,282 outstanding options as of December 31, 2016. During the year ended December 31, 2017, 47,956 shares of MAA's common stock were acquired from employees to satisfy minimum tax withholding obligations that arose upon vesting of restricted stock granted pursuant to approved plans. During the year ended December 31, 2016, 22,067 shares were acquired for such purposes.

Preferred Stock

As of December 31, 2017, MAA had one outstanding series of cumulative redeemable preferred stock which has the following characteristics:

Description	Outstanding Shares	Liquidation Preference(1)	Optional Redemption Date	Redemption Price (2)	Stated Dividend Yield	Approximate Dividend Rate
Series I	867,846	$50.00	10/1/2026	$50.00	8.50%	$4.25

⁽¹⁾ The total liquidation preference for the outstanding preferred stock is $43.4 million.

⁽²⁾ The redemption price is the price at which the preferred stock is redeemable, at MAA's option, for cash.

F-35

Noncontrolling Interests

Noncontrolling interests in the accompanying consolidated financial statements relates to the limited partnership interests in the Operating Partnership owned by the holders of the Class A OP Units, or Class A Units. MAA is the sole general partner of the Operating Partnership and holds all of the outstanding Class B OP Units, or Class B 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 Units or Class B Units changes the ownership percentage of both the noncontrolling interests and MAA. The issuance of Class B Units generally occurs when MAA issues common stock and the issuance proceeds are contributed to the Operating Partnership in exchange for Class B 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 Unit that were equivalent to the economic rights in respect to each share of MAA common stock. The holders of Class A Units may redeem each of their units in exchange for one share of common stock in MAA or cash, at the option of MAA. At December 31, 2017, a total of 4,191,586 Class A Units were outstanding and redeemable by the holders of the units for 4,191,586 shares of MAA common stock or approximately $421.5 million, based on the closing price of MAA’s common stock on December 31, 2017 of $100.56 per share, at MAA’s option. At December 31, 2016, a total of 4,220,403 Class A Units were outstanding and redeemable by the holders of the units for 4,220,403 shares of MAA common stock or approximately $413.3 million, based on the closing price of MAA’s common stock on December 31, 2016 of $97.92 per share, at MAA’s option. The Operating Partnership pays the same per unit distribution in respect to the Class A Units as the per share distribution MAA pays in respect to the common stock. The Operating Partnership's net income for 2017, 2016 and 2015 was allocated approximately 3.6%, 5.0% and 5.2%, respectively, to holders of Class A Units and 96.4%, 95.0% and 94.8%, respectively, to MAA as the holder of all Class B Units.

MAA further determined that the noncontrolling interest in its consolidated real estate entity totaling $2.3 million (see Note 1) met the criterion to be classified and accounted for as a component of permanent equity.

Direct Stock Purchase and Distribution Reinvestment Plan

MAA has a Dividend and Distribution Reinvestment and Share Purchase Plan, or DRSPP, pursuant to which MAA’s common shareholders have the ability to reinvest all or part of their distributions from MAA into shares of MAA’s common stock and holders of Class A Units have the ability to reinvest all or part of their distributions from the Operating Partnership into MAA’s common stock. The DRSPP also provides the opportunity to make optional cash investments in MAA's common stock of at least $250, but not more than $5,000 in any given month, free of brokerage commissions and charges. MAA, in its absolute discretion, may grant waivers to allow for optional cash payments in excess of $5,000. To fulfill its obligations under the DRSPP, MAA may either issue additional shares of common stock or repurchase common stock in the open market. MAA has registered with the SEC the offer and sale of up to 9,600,000 shares of common stock pursuant to the DRSPP. MAA may elect to sell shares under the DRSPP at up to a 5% discount. Shares of MAA's common stock totaling 9,568 in 2017, 7,906 in 2016, and 8,562 in 2015 were acquired by participants under the DRSPP. MAA did not offer a discount for optional cash purchases in 2017, 2016 or 2015.

10.    PARTNERS' CAPITAL OF MAALP

OP Units

Interests in MAALP are represented by OP Units. As of December 31, 2017, there were 117,834,752 OP Units outstanding, 113,643,166 or 96.4% of which were owned by MAA, MAALP's general partner. The remaining 4,191,586 OP Units were owned by non-affiliated limited partners, or Class A Limited Partners. As of December 31, 2016, there were 117,738,615 OP Units outstanding, 113,518,212 or 96.4% of which were owned by MAA and 4,220,403 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 the Operating Partnership subject to the restrictions specifically contained within MAALP's agreement of limited partnership, or the Partnership Agreement. Unless otherwise stated in the Partnership Agreement of MAALP, 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 the Operating Partnership's assets; and distribution of Operating Partnership cash or other assets in accordance with the Partnership Agreement. MAA can generally,

F-36

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, the Operating Partnership may issue Class A Units and Class B Units. Class A Units may only be held by limited partners who are not affiliated with MAA, in its capacity as general partner of the Operating Partnership, while Class B Units may only be held by MAA, in its capacity as general partner of the Operating Partnership, and as of December 31, 2017, a total of 4,191,586 Class A Units in the Operating Partnership were held by limited partners unaffiliated with MAA, while a total of 113,643,166 Class B Units were held by MAA. In general, the limited partners do not have the power to participate in the management or control of the Operating Partnership'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 Units is also limited by the Partnership Agreement.

Net income (after allocations to preferred ownership interests) is allocated to the general partner and limited partners based on their respective ownership percentages of the Operating Partnership. Issuance or redemption of additional Class A Units or Class B Units changes the relative ownership percentage of the partners. The issuance of Class B Units generally occurs when MAA issues common stock and the proceeds from that issuance are contributed to the Operating Partnership 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, the Operating Partnership generally redeems an equal number of Class B 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 the Operating Partnership. Holders of the Class A Units may require MAA to redeem their Class A Units, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per Class A 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 Unit so redeemed.

At December 31, 2017, a total of 4,191,586 Class A Units were outstanding and redeemable for 4,191,586 shares of MAA common stock, with an approximate value of $421.5 million, based on the closing price of MAA’s common stock on December 31, 2017 of $100.56 per share. At December 31, 2016, a total of 4,220,403 Class A Units were outstanding and redeemable for 4,220,403 shares of MAA common stock, with an approximate value of $413.3 million, based on the closing price of MAA’s common stock on December 31, 2016 of $97.92 per share. The Operating Partnership pays the same per unit distribution in respect to the OP Units as the per share dividend MAA pays in respect to its common and preferred stock.

11.     EMPLOYEE BENEFIT PLANS

The following provides details of the employee benefit plans not previously discussed in Note 5.

401(k) Savings Plans

MAA's 401(k) Savings Plan, or 401(k) Plan, is a defined contribution plan that satisfies the requirements of Section 401(a) and 401(k) of the Code. Subsequent to the Merger, eligible employees of Post Properties continued to actively participate in the Post Properties 401(k) Plan, which also is a defined contribution plan that satisfies the requirements of Section 401(a) and 401(k) of the Code. MAA's Board of Directors has the discretion to approve matching contributions to these plans. MAA's contributions to these plans were approximately $2.8 million, $2.0 million and $1.0 million for the years ended December 31, 2017, 2016 and 2015, respectively.

Non-Qualified Deferred Compensation Retirement Plan

MAA has adopted a non-qualified deferred compensation retirement plan for certain selected executive employees. Under the terms of the plan, employees may elect to defer a percentage of the compensation and bonus, and MAA may, but is not obligated to, match a portion of their salary deferral. MAA’s match to this plan for the years ended December 31, 2017, 2016 and 2015 was approximately $249,000, $96,000 and $106,000, respectively.

Non-Qualified Deferred Compensation Plan for Outside Company Directors

In 1998, MAA established the Non-Qualified Deferred Compensation Plan for Outside Company Directors, or the Directors Deferred Compensation Plan, which allows non-employee directors to defer their director fees by having the fees held by MAA

F-37

as shares of MAA's common stock. Directors can also choose to have their annual restricted stock grants issued into the Directors Deferred Compensation Plan. Amounts deferred through the Directors Deferred Compensation Plan are distributed to the directors in two annual installments beginning in the first 90 days of the year following the director’s departure from the board. Participating directors may choose to have the amount issued to them in shares of MAA's common stock or paid to them as cash at the market value of MAA's common stock as of the end of the year the director ceases to serve on the board.

For the years ended December 31, 2017, 2016 and 2015, directors deferred 12,293 shares, 10,166 shares and 8,466 shares of common stock, respectively, with weighted-average grant date fair values of $101.34, $97.99 and $78.62, respectively, into the Directors Deferred Compensation Plan. The shares of common stock held in the Directors Deferred Compensation Plan are classified outside of permanent equity in redeemable stock with changes in redemption amount recorded immediately to retained earnings because the directors have redemption rights not solely within the control of MAA. Additionally, any shares that become mandatorily redeemable because a departed director has elected to receive a cash payout are recorded as a liability. MAA did not record a liability related to mandatorily redeemable shares for the years ended December 31, 2017, 2016 and 2015.

Employee Stock Ownership Plan

MAA’s Employee Stock Ownership Plan, or ESOP, is a non-contributory stock bonus plan that satisfies the requirements of Section 401 (a) of the Code. On December 31, 2010, the ESOP was frozen by amendment, whereby effective January 1, 2011, no additional employees became eligible for the plan, no additional contributions were made to the ESOP, and all Participants with an account balance under the ESOP became 100% vested. The Company did not contribute to the ESOP during 2017, 2016 or 2015. As of December 31, 2017, there were 145,598 shares outstanding with a fair value of $14.6 million.

12.     COMMITMENTS AND CONTINGENCIES

Land and Equipment Leases

The Company has a ground lease expiring in 2074 related to one of its apartment communities acquired in the Merger. This lease contains stated rent increases that generally compensate for the impact of inflation.  The Company also has office, equipment and other operating leases.  Future minimum lease payments for non-cancelable land, equipment and other operating leases at December 31, 2017, were as follows (in thousands):

	Minimum Lease Payments
2018	$	882
2019	724
2020	708
2021	718
2022	733
Thereafter	62,788
Total	$	66,553

Legal Proceedings

In September 2010, the United States Department of Justice, or DOJ, filed suit against Post Properties (and by virtue of the Merger, MAA) in the United States District Court for the District of Columbia alleging that certain of Post Properties’ apartments violated accessibility requirements of the Fair Housing Act, or FHA. and the Americans with Disabilities Act of 1990, or ADA. The DOJ is seeking, among other things, an injunction against MAA, requiring MAA to retrofit the properties and comply with FHA and ADA standards in future design and construction, as well as monetary damages and civil penalties. No trial date has been set.

In December 2017, a non-profit civil rights organization filed suit against MAA and the Operating Partnership in the United States District Court for the District of Columbia. The suit alleges the Company maintained and enforced a criminal records screening policy at certain of its apartment communities, all of which are apartments acquired from Post Properties in the Merger, which violates the FHA. The suit seeks injunctive relief, actual and punitive damages and attorneys' fees and costs.

The Company is subject to various other legal proceedings and claims that arise in the ordinary course of our business

F-38

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 such matters, either individually or in the aggregate, will have a material adverse effect on the Company's financial position, results of operations or cash flows.

As of December 31, 2017 and December 31, 2016, the Company's accrual for loss contingencies, including the legal proceedings referenced above, was $32.1 million and $42.1 million in the aggregate, respectively. The loss contingencies are presented in "Accrued expenses and other liabilities" in the accompanying Consolidated Balance Sheets.

13.    RELATED PARTY TRANSACTIONS

The Company holds investments in unconsolidated affiliates accounted for under the equity method of accounting. All significant intercompany transactions were eliminated in the accompanying consolidated financial statements.

The cash management of the Company is managed by the Operating Partnership. In general, cash receipts are remitted to the Operating Partnership and all cash disbursements are funded by the Operating Partnership. As a result of these transactions, the Operating Partnership had a payable to MAA, its general partner, of $19,000 at each of the years ended December 31, 2017, and 2016. The Partnership Agreement does not require the due to/due from balance to be settled in cash until liquidation of the Operating Partnership, and therefore, there is no regular settlement schedule for such amounts.

14.     SEGMENT INFORMATION

As of December 31, 2017, the Company owned or had an ownership interest in 302 multifamily apartment communities in 17 different states and the District of Columbia from which it derived all significant sources of earnings and operating cash flows. Management evaluates performance and determines resource allocations of each of the apartment communities on a Large Market Same Store, Secondary Market 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 three reportable operating segments for the Company:

• Large Market Same Store communities are generally communities in markets with a population of at least 1 million and at least 1% of the total public multifamily REIT units that the Company has owned and has been stabilized for at least a full 12 months.

• Secondary Market Same Store communities are generally communities in markets with populations of more than 1 million but less than 1% of the total public multifamily REIT units or markets with populations of less than 1 million that the Company has owned and has been stabilized for at least a full 12 months.

• Non-Same Store and Other includes recent acquisitions, communities in development or lease-up, communities that have been identified for disposition, and communities that have undergone a significant casualty loss. Also included in non-same store communities are non-multifamily activities.

On the first day of each calendar year, the Company determines the composition of its same store operating segments for that year as well as adjust 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 it 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 Company utilizes NOI in evaluating the performance of the 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 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 related to property operating performance.

All properties acquired as a result of the Merger have been placed in the Non-Same Store and Other operating segment, as the properties were recent acquisitions and had not been owned and stabilized for at least 12 months as of the first day of the applicable calendar year.

F-39

⁽¹⁾  Encumbered by $80.0 million Fannie Mae facility, with $80.0 million available and outstanding with a variable interest rate of 1.8% on which there exists one interest rate cap for $25 million at a rate of 4.50% at December 31, 2017.

⁽²⁾  Encumbered by a $125.2 million loan with a fixed interest rate of 5.08% which matures on June 10, 2021.

⁽³⁾  The aggregate cost for federal income tax purposes was approximately $10.8 billion at December 31, 2017. The aggregate cost for book purposes exceeds the total gross amount of real estate assets for federal income tax purposes, principally due to purchase accounting adjustments recorded under accounting principles generally accepted in the United States of America.

⁽⁴⁾  Depreciation is on a straight-line basis over the estimated useful asset life which ranges from 8 to 40 years for land improvements and buildings, 5 years for furniture, fixtures and equipment, and 6 months for fair market value of residential leases.

Organization and Summary of Significant Accounting Policies

Consolidation and Basis of Presentation and Significant Accounting Policies [Abstract]

ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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" refers 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" means 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 December 31, 2017, MAA owned 113,643,166 OP Units (or approximately 96.4% of the total number of OP units). MAA conducts substantially all of its business and holds substantially all of its assets 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 consolidated financial statements of MAA and MAALP 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 is a multifamily focused, self-administered and self-managed real estate 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 partner interests in the Operating Partnership; therefore, MAA does not conduct business itself, other than 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 OP Units, 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 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. Redeemable common units represent the number of outstanding OP Units as of the date of the applicable balance sheet, valued at the greater of the closing market price of MAA's common stock or the aggregate value of the individual partners' capital balances. Holders of OP Units (other than MAA and its corporate affiliates) 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.

On December 1, 2016, MAA completed a merger with Post Properties, Inc., or Post Properties. Pursuant to the Agreement and Plan of Merger, or the Merger Agreement, Post Properties merged with and into MAA, with MAA continuing as the surviving corporation, or the Parent Merger, and Post Apartment Homes, L.P., or Post LP, merged with and into MAALP, with MAALP continuing as the surviving entity, or the Partnership Merger. The Company refers to the Parent Merger, together with the Partnership Merger, as the Merger in this Annual Report on Form 10-K. Under the terms of the Merger Agreement, each share of Post Properties common stock was converted into the right to receive 0.71 of a newly issued share of MAA common stock, including the right, if any, to receive cash in lieu of fractional shares of MAA common stock. In addition, each limited partner interest in Post LP designated as a "Class A Unit" automatically converted into the right to receive 0.71 of a newly issued partnership unit of MAALP. Also, each share of Post Properties' 8 1/2% Series A Cumulative Redeemable Preferred Stock, which is referred to as the Post Properties Series A preferred stock, was automatically converted into the right to receive one newly issued share of MAA's 8.50% Series I Cumulative Redeemable Preferred Stock, $0.01 par value per share, which is referred to as MAA Series I preferred stock. Each newly issued share of MAA Series I preferred stock has substantially the same rights, preferences, privileges, and voting powers as those of the Post Properties Series A preferred stock. The net assets and results of operations of Post Properties are included in the consolidated financial statements from the closing date going forward. See further discussion regarding the Merger in Note 2.

As of December 31, 2017, the Company owned and operated 301 apartment communities through the Operating Partnership. As of December 31, 2017, MAA also owned a 35.0% interest in an unconsolidated real estate joint venture and a 31.0% interest in an unconsolidated limited partnership. As of December 31, 2017, the Company had three development communities under construction totaling 937 apartment units, of which 240 units were completed during the year. Total expected costs for these three development projects are $214.0 million, of which $167.7 million had been incurred through December 31, 2017. The Company expects to complete construction on one project by the first quarter of 2018, one project by the third quarter of 2018 and one project by the fourth quarter of 2018. Twenty-nine of the multifamily properties include retail components with approximately 620,000 square feet of gross leasable space. The Company also has four wholly-owned commercial properties, which were acquired through the Merger, with approximately 230,000 square feet of combined gross leasable area.

Basis of Presentation and Principles of Consolidation

The accompanying 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 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 approximately 92.5% to 100% of all consolidated subsidiaries, including the Operating Partnership. The 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, 92.5% to 100% of all consolidated subsidiaries. In management's opinion, all adjustments necessary for a fair presentation of the 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, since 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 "Investment in Unconsolidated Affiliates" below).

Changes in Presentation

In an effort to align the Company's presentation of assets, liabilities and equity in the Consolidated Balance Sheets with the presentation utilized by competitors in its industry and to enhance comparability, the Company combined "Buildings and improvements", "Furniture, fixtures and equipment" and "Corporate properties, net" into one line item "Buildings and improvements and other." The Company also combined "Deferred financing costs, net", "Other assets", and "Goodwill" into a single line item "Other assets." Finally, the Company aggregated "Accounts payable", "Fair market value of interest rate swaps", "Security deposits" and "Accrued expenses and other liabilities" into one line item "Accrued expenses and other liabilities". Prior year amounts have been changed to conform to the Company's current year presentation. These changes in presentation had no effect on the Company's total assets or total liabilities and equity.

In an effort to align the Company's presentation of revenues and expenses in the Consolidated Statements of Operations with the presentation utilized by competitors in its industry and to enhance comparability, the Company combined "Rental revenues", "Other property revenues" and "Management fee income" into one line item "Rental and other property revenues". The Company also combined "Personnel", "Building repairs and maintenance", "Utilities", "Landscaping" and "Other operating" into one line item "Operating expense, excluding real estate taxes." Additionally, the Company combined "Merger related expense" and "Integration expense" into one line item "Merger and integration expense." Further, the Company aggregated the line items "Acquisition expense", "Interest and other non-property income (expense)", "Loss on debt extinguishment" and "Net casualty loss (gain)" into a single line item "Other non-operating expense." Prior year amounts have been changed to conform to the Company's current year presentation. These changes in presentation had no effect on the Company's net income.

In an effort to align the Company's presentation of cash flows from operating activities and investing activities within the Consolidated Statements of Cash Flows with the presentation utilized by competitors in its industry and to enhance comparability, the Company combined "Retail revenue accretion"; "Redeemable stock expense"; "Gain (loss) from investments in real estate joint venture"; "Gain (loss) on debt extinguishment"; "Derivative interest credit"; "Settlement of forward swaps"; "Net casualty gain (loss)" and "Changes in restricted cash, other assets, accounts payable, accrued expenses and security deposits" into one line "Net change in operating accounts and other" within the cash flows from operating activities section. In addition, the Company aggregated "Normal capital improvements", "Construction capital and other", "Renovations to existing assets" and "Development" into one line "Capital improvements, development and other" within the cash flows from investing activities section. No presentation changes were made to the cash flows from financing activities section of the Consolidated Statements of Cash Flows. Prior year amounts have been changed to conform to the Company's current year presentation. These changes in presentation had no effect on the Company's ending cash and cash equivalents balance and did not impact the classification of cash flows between operating, investing and financing activities.

Noncontrolling Interests

At December 31, 2017, the Company had two types of noncontrolling interests, (1) noncontrolling interests related to the common unitholders of its Operating Partnership (see Note 10) and (2) noncontrolling interest related to its consolidated real estate entity (see "Investment in Consolidated Real Estate Joint Venture" below).

Use of Estimates

Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses to prepare these financial statements and notes in conformity with GAAP. Actual results could differ from those estimates.

Revenue Recognition and Real Estate Sales Gain Recognition

The Company primarily leases multifamily residential apartments under operating leases generally with terms of one year or less, which are recorded as operating leases. Rental lease revenues are recognized in accordance with Accounting Standards Codification, or ASC, 840, Leases, using a method that represents a straight-line basis over the term of the lease. Rental income represents gross market rent less adjustments for concessions, vacancy loss and bad debt. Other non-lease revenues are recognized in accordance with ASC, 605, Revenue Recognition, when such sources of revenue are earned, and the amounts are fixed and determinable. The Company records gains and losses on real estate sales in accordance with accounting standards governing the sale of real estate. For sale transactions meeting the requirements for the full accrual method, the Company removes the assets and liabilities from its Consolidated Balance Sheets and recognizes the gain or loss in the period the transaction closes.

Rental Costs

Costs associated with rental activities are expensed as incurred and include advertising expenses, which were approximately$18.8 million, $13.0 million, and $13.5 million for the years ended December 31, 2017, 2016, and 2015, respectively.

Real Estate Assets and Depreciation and Amortization

Real estate assets are carried at depreciated cost and consist of land, buildings and improvements and other and development and capital improvements in progress (see "Development Costs" below). Repairs and maintenance costs are expensed as incurred, while significant improvements, renovations, and recurring capital replacements are capitalized and depreciated over their estimated useful lives. Recurring capital replacements typically include scheduled carpet replacement, new roofs, HVAC units, plumbing, concrete, masonry and other paving, pools and various exterior building improvements. In addition to these costs, the Company also capitalizes salary costs directly identifiable with renovation work. These expenditures extend the useful life of the property and increase the property’s fair market value. The cost of interior painting, vinyl flooring and blinds are expensed as incurred.

Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets, which range from five to 40 years. The Consolidated Balance Sheets line "Buildings and improvements and other" includes land improvements and buildings, which have a useful life ranging from eight to 40 years, as well as furniture, fixtures and equipment, which have a useful life of five years.

Development Costs

Development projects and the related carrying costs, including interest, property taxes, insurance and allocated direct development salary cost during the construction period, are capitalized and reported in the accompanying Consolidated Balance Sheets as "Development and capital improvements in progress" during the construction period. Interest is capitalized in accordance with accounting standards governing the capitalization of interest. Upon completion and certification for occupancy of individual buildings or floors within a development, amounts representing the completed portion of total estimated development costs for the project are transferred to "Land" and "Buildings and improvements and other" as real estate held for investment. Capitalization of interest, property taxes, insurance and allocated direct development salary costs cease upon the transfer. The assets are depreciated over their estimated useful lives. Total capitalized costs (including capitalized interest, salaries and real estate taxes) during the years ended December 31,2017, 2016 and 2015 was approximately $11.0 million, $2.7 million and $2.3 million, respectively. Certain costs associated with the lease-up of development projects, including cost of model units, furnishings, signs and grand openings, are capitalized and amortized over their respective estimated useful lives. All other costs relating to renting development projects are expensed as incurred.

Acquisition of Real Estate Assets

The Company adopted ASU 2017-01, Clarifying the Definition of a Business (Topic 805), effective January 1, 2017. Subsequent to the adoption of ASU 2017-01, most acquisitions of operating properties qualify as asset acquisitions rather than business combinations. Accordingly, the cost of the real estate acquired is allocated to the acquired tangible assets, consisting of land, buildings and improvements and other, and identified intangible assets, consisting of the value of in-place leases and other contracts, on a relative fair value basis.

The purchase price of an acquired property is allocated based on the relative fair value of the individual components as a proportion of the total assets acquired. The Company allocates the cost of the tangible assets of an acquired property by valuing the building as if it were vacant, based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a building using methods similar to those used by independent appraisers. These methods include using stabilized net operating income, or NOI, and market specific capitalization and discount rates. In allocating the cost of identified intangible assets of an acquired property, the in-place leases are valued based on current rent rates and time and cost to lease a unit. Management concluded that the residential leases acquired in connection with each of its property acquisitions approximate at-market rates since the residential lease terms generally do not extend beyond one year.

For residential leases, the fair value of the in-place leases and resident relationships is amortized over 6 months, which represents the estimated remaining term of the tenant leases. For commercial leases, the fair value of in-place leases and resident relationships is amortized over the remaining term of the commercial leases. The amount of these lease intangibles included in "Other assets" totaled $11.2 million and $42.4 million as of December 31, 2017, and 2016, respectively. Accumulated amortization for these leases totaled $4.1 million and $7.3 million as of December 31, 2017 and 2016, respectively. The amortization of these intangibles recorded as "Depreciation and amortization expense" was $29.4 million, $8.7 million, and $5.0 million for the years ended December 31, 2017, 2016, and 2015, respectively. The estimated aggregate future amortization expense of in-place leases is approximately $2.8 million, $1.6 million, $0.8 million, $0.5 million, and $0.3 million for the years ended December 31, 2018, 2019, 2020, 2021, and 2022, respectively.

As a result of the adoption of ASU 2017-01, the Company believes most acquisitions of operating properties will qualify as asset acquisitions and associated transaction costs will be capitalized. Acquisition costs include appraisal fees, title fees, broker fees, and other legal costs to acquire the property. For the year ended December 31, 2017, acquisition costs totaling $1.3 million related to the Company's acquisitions of Charlotte at Midtown and Acklen West End were capitalized and allocated to the assets based on the relative fair market value of those underlying assets; see Note 15 for additional information on 2017 acquisitions. For the accounting policy on larger, portfolio style acquisitions which qualify as business combinations (rather than asset acquisitions), see Note 2.

Impairment of Long-lived Assets

The Company accounts for long-lived assets in accordance with the provisions of accounting standards for the impairment or disposal of long-lived assets. Management periodically evaluates long-lived assets, including investments in real estate, for indicators that would suggest that the carrying amount of the assets may not be recoverable. The judgments regarding the existence of such indicators are based on factors such as operating performance, market conditions and legal factors. Long-lived assets, such as real estate assets, equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the Consolidated Balance Sheets and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group or a property classified as held for sale are presented separately in the appropriate asset and liability sections of the Consolidated Balance Sheets.

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. 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 may 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 expected ultimately 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. See Note 12 for additional information on loss contingencies.

Undeveloped Land

Undeveloped land includes sites intended for future multifamily developments, sites for future commercial development and sites intended for residential use, which are carried at the lower of cost or fair value in accordance with GAAP and any costs incurred prior to commencement of pre-development activities are expensed as incurred.

Investment in Unconsolidated Affiliates

Immediately prior to the effective date of the Merger, Post Properties was an investor, together with other institutional investors, in a limited liability company, or the Apartment LLC, that indirectly owned one apartment community, Post Massachusetts Avenue, located in Washington, D.C.  Post Properties owned a 35.0% equity interest in the unconsolidated joint venture, which was retained by MAA immediately following the close of the Merger and as of December 31, 2017. The Company provides property and asset management services to the Apartment LLC for which it earns fees. The joint venture was determined to be a VIE, but the Company is not designated as a primary beneficiary. As a result, the Company accounts for its investment in the Apartment LLC using the equity method of accounting as the Company is able to exert significant influence over the joint venture but does not have a controlling interest. At December 31, 2017, the Company's investment in the Apartment LLC totaled $45.0 million.  

During September 2017, a subsidiary of the Operating Partnership entered into a limited partnership together with a general partner and other limited partners to form Real Estate Technology Ventures, L.P. The Operating Partnership indirectly owns 31.0% of the limited partnership. The limited partnership was determined to be a VIE, but the Company is not designated as a primary beneficiary. As a result, the Company accounts for its investment in the limited partnership using the equity method of accounting as the investment is considered more than minor. At December 31, 2017, the Company's investment in the limited partnership totaled $1.5 million. The Company is committed to make additional capital contributions totaling $13.5 million if and when called by the general partner of the limited partnership prior to September 2022.

Investment in Consolidated Real Estate Joint Venture

In 2015, Post Properties entered into a joint venture arrangement with a private real estate company to develop, construct and operate a 359-unit apartment community in Denver, Colorado. At December 31, 2017, the Company owned a 92.5% equity interest in the consolidated joint venture. In 2015, the joint venture acquired the land site and initiated the development of the apartment community. The venture partner will generally be responsible for the development and construction of the community and the Company will continue to manage the community upon its completion. The joint venture was determined to be a VIE with the Company designated as the primary beneficiary. As a result, the accounts of the joint venture are consolidated by the Company. At December 31, 2017, the consolidated assets, liabilities and equity included construction in progress of $36.9 million; buildings and improvements and other of $33.9 million; land of $14.9 million; and accrued expenses and other liabilities of $6.5 million.

Cash and Cash Equivalents

Investments in money market accounts and certificates of deposit with original maturities of three months or less are considered to be cash equivalents.

Restricted Cash

Restricted cash consists of security deposits required to be held separately, escrow deposits held by lenders for property taxes, insurance, debt service, and replacement reserves, and exchanges under Section 1031(b) of the Internal Revenue Code of 1986, as amended, or the Code. Section 1031(b) exchanges are treated as investing activities in the Consolidated Statements of Cash Flows.

Other Assets

Other assets consist primarily of receivables and deposits from residents, the value of derivative contracts, deferred rental concessions, deferred financing costs relating to lines of credit, and other prepaid expenses. Also included in other assets are the fair market value of in-place leases and resident relationships, net of accumulated amortization.

Accrued Expenses and Other Liabilities

Accrued expenses consist of accrued dividends payable, accrued real estate taxes, accrued interest payable, accrued loss contingencies, accounts payable, fair market value of interest rate swaps (see Note 7), security deposits not related to restricted cash, other accrued expenses, and unearned income. Significant accruals include accrued dividends payable of $108.7 million and $102.4 million at December 31, 2017 and 2016, respectively; accrued real estate taxes of $99.6 million and $97.6 million at December 31, 2017 and 2016, respectively; unearned income of $40.8 million and $39.4 million at December 31, 2017 and 2016, respectively; accrued loss contingencies of $32.1 million and $42.1 million at December 31, 2017 and 2016, respectively; security deposits of $19.1 million and $18.8 million at December 31, 2017 and 2016, respectively; and accrued interest payable of $18.1 million and $19.1 million at December 31, 2017 and 2016, respectively.

Self-Insurance

The Company is self-insured for workers' compensation claims up to $500,000 and for general liability claims up to $100,000. The Company accrues for expected liabilities less than these amounts based on third party actuarial estimates of ultimate losses. Claims exceeding these amounts are insured by a third party.

Income Taxes

MAA has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, or the Code, and intends to continue to operate in such a manner. The current and continuing qualification as a REIT depends on MAA's ability to meet the various requirements imposed by the Code, which are related to organizational structure, distribution levels, diversity of stock ownership and certain requirements with respect to the nature and diversity of MAA’s assets and sources of MAA’s gross income. As long as MAA qualifies for taxation as a REIT, it will generally not be subject to United States federal corporate income tax on its taxable income that is currently distributed to shareholders. This treatment substantially eliminates the "double taxation" (i.e., income taxation at both the corporate and shareholder levels) that generally results from an investment in a corporation. Even if MAA qualifies as a REIT, MAA may be subject to United States federal income and excise taxes in certain situations, such as if MAA fails to distribute timely all of its taxable income with respect to a taxable year. MAA also will be required to pay a 100% tax on any net income on non-arm’s length transactions between MAA and one of its taxable REIT subsidiaries, or TRS. In addition, MAA could be subject to the alternative minimum tax. Furthermore, MAA and its shareholders may be subject to state or local taxation in various state or local jurisdictions, including those in which MAA transacts business or its shareholders reside, and the applicable state and local tax laws may not conform to the United States federal income tax treatment. Any taxes imposed on MAA would reduce its operating cash flow and net income.

Certain of the Company's operations and activities, including asset management and risk management, are conducted through TRSs, which are subject to United States federal corporate income tax without the benefit of the dividends paid deduction applicable to REITs. MAA accounts for deferred taxes of a TRS by recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that all or some portion of the deferred tax assets will not be realized. Based on this evaluation, at December 31, 2017, net of the valuation allowance, the net deferred tax assets were reduced to zero. MAA recognizes liabilities for uncertain income tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires MAA to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. MAA classifies interest related to income tax liabilities, and if applicable, penalties, as a component of income tax expense. As of December 31, 2017, MAA did not have any unrecognized tax benefits, and MAA does not believe that there will be any material changes in its unrecognized tax positions over the next 12 months. "Income tax expense" reflected in the Consolidated Statements of Operations represents the Texas-based margin tax for all Texas properties and state taxes for a TRS.

Derivative Financial Instruments

The Company utilizes certain derivative financial instruments, primarily interest rate swaps and interest rate caps, during the normal course of business to manage, or hedge, the interest rate risk associated with our variable rate debt or as hedges in anticipation of future debt transactions to manage well-defined interest rate risk associated with the transaction.

Additionally, the 867,846 shares of MAA's Series I preferred stock issued as consideration in the Merger are redeemable, at the Company's option, beginning on October 1, 2026, at the redemption price of $50 per share (see Note 9). The redemption feature embedded in the preferred stock was evaluated in accordance with ASC 815, Derivatives and Hedging, and the Company determined that it was required to bifurcate the value associated with the redemption feature from the host instrument, the perpetual preferred shares. The redemption feature embedded in the MAA Series I preferred stock is reported as a derivative asset in "Other assets" in the accompanying Consolidated Balance Sheets at its fair value and will be adjusted to its fair value at each reporting date, with a corresponding adjustment to "Other non-operating income (expense)". See Note 7 for further discussion on derivatives and the fair value of financial instruments.

Fair Value Measurements

The Company applies the guidance in ASC Topic 820, Fair Value Measurements and Disclosures, to the valuation of real estate assets recorded at fair value, if any; 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 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.

Assets Held for Sale

As of December 31, 2017, one land parcel was classified as held for sale. The criteria for classifying the land parcel as held for sale were met during June 2017; however, the sale is not expected to close until the first quarter of 2018. As a result, the assets associated with the land parcel were presented as held for sale in the accompanying Consolidated Balance Sheets.

Recent Accounting Pronouncements

The following table provides a brief description of recent accounting pronouncements that could have a material effect on the Company's consolidated financial statements:

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
ASU 2014-09, Revenue from Contracts with Customers	The ASU establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services as outlined in a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied. Income from lease contracts is specifically excluded from this ASU.	The ASU is effective for annual reporting periods beginning after December 15, 2017 Early adoption is permitted.	The amendments may be applied using the full retrospective transition method or by using the modified retrospective transition method with a cumulative effect recognized as of the date of initial application. The Company adopted ASU 2014-09 effective January 1, 2018, using the modified retrospective approach. The majority of the Company's revenue is derived from real estate lease contracts, which falls outside the scope of the ASU. The Company has completed its analysis of non-lease related revenues. The adoption of the ASU does not have a material impact on the Company's consolidated financial statements or to the Company's internal accounting policies. The guidance does require additional disclosures regarding the nature and timing of the Company's revenue transactions upon adoption.
ASU 2016-02, Leases	The ASU amends existing accounting standards for lease accounting and establishes the principles for lease accounting for both the lessee and lessor. The amendment requires an entity to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendment also requires certain quantitative and qualitative disclosures about leasing arrangements.	The ASU is effective for annual reporting periods beginning after December 15, 2018; however, early adoption is permitted.	The standard must be adopted using a modified retrospective transition and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. Management is currently evaluating the impact the standard will have on the consolidated financial statements and related disclosures upon adoption. The Company plans to adopt the ASU effective January 1, 2019.

ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)	The ASU clarifies how several specific cash receipts and cash payments are to be presented and classified on the statement of cash flows, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration made after a business combination, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of predominance principle.	The ASU is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted.	Each amendment in this standard must be applied prospectively, retrospectively, or as of the beginning of the earliest comparative period presented in the year of adoption, depending on the type of amendment. The Company adopted ASU 2016-15 as of January 1, 2018. Management has determined three of the eight transactions in the update are relevant to MAA and its cash flows, including: 1) debt prepayment or debt extinguishment costs, 2) proceeds from the settlement of insurance claims and 3) distributions received from equity method investees. Management performed an analysis and determined only the change in classification of debt prepayment or debt extinguishment costs, which is currently reported in operating activities, will have a significant impact on the consolidated statements of cash flows. Upon adoption in the first quarter of 2018, $1.7 million of cash outflows for debt prepayment or extinguishment costs currently reported in net cash provided by operating activities for the year ended December 31, 2017, will be re-classified to and reported in net cash used in financing activities.
ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (A Consensus of the FASB Emerging Issues Task Force)	The ASU requires restricted cash to be presented with cash and cash equivalents when reconciling the beginning and ending amounts in the consolidated statements of cash flows.	The ASU is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted.	The update should be applied retrospectively to each period presented. The Company adopted ASU 2016-18 as of January 1, 2018. The Company currently reports the change in restricted cash within the operating and investing activities in the consolidated statements of cash flows. Upon adoption in the first quarter of 2018, cash and cash equivalents reported in the consolidated statements of cash flows for the year ended December 31, 2017 will increase by approximately $78.1 million to reflect the restricted cash balances. Additionally, net cash used in investing activities will decrease by $10.6 million for the year ended December 31, 2017.
ASU 2017-12, Derivatives and Hedging (Topic 815)	The ASU clarifies hedge accounting requirements, improves disclosure of hedging arrangements, and better aligns risk management activities and financial reporting for hedging relationships.	The ASU is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted.	The standard should be adopted using a modified retrospective approach. This adoption method will require the Company to recognize the cumulative effect of initially applying ASU 2017-12 as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings. The Company elected to early adopt the ASU as of January 1, 2018. Management has completed its assessment of the impact the standard has on the Company's consolidated financial statements and related disclosures. Adoption of the ASU does not have a material impact on the consolidated financial statements or the Company's internal accounting policies.

BUSINESS COMBINATIONS

BUSINESS COMBINATIONS

Merger of MAA and Post Properties

The Company completed the Merger on December 1, 2016. As part of the Merger, the Company acquired 61 wholly-owned apartment communities encompassing 24,138 units, including 269 apartment units in one community held in an unconsolidated entity, and 2,262 apartment units in six communities that were under development at the date of the Merger. Post Properties had operations in ten markets across the United States. In addition to the apartment communities, the Company also acquired four commercial properties, totaling approximately 232,000 square feet of combined gross leasable area. The consolidated net assets and results of operations of Post Properties are included in the Company's consolidated financial statements from the closing date going forward.

The total purchase price of approximately $4.0 billion was determined based on the number of shares of Post Properties' common stock, the number of shares of Post Properties’ Series A preferred stock, and the number of shares of Post LP's Class A Units of limited partnership interest outstanding as of December 1, 2016, in addition to cash consideration provided by the Operating Partnership immediately prior to the Merger to retire a $300.0 million unsecured term loan and a $162.0 million line of credit. In all cases in which MAA’s common stock price was a determining factor in arriving at final consideration for the Merger, the stock price used to determine the purchase price was the opening price of MAA’s common stock on December 1, 2016 ($91.41 per share). At the date of acquisition, the MAA Series I preferred stock consideration was valued at $77 per share, which included a $14.24 per share bifurcated call option (See Notes 7 and 9).The total purchase price also included $2.0 million of other consideration, a majority of which related to assumed stock compensation plans. As a result of the Merger, the Company issued approximately 38.0 million shares of MAA common stock, approximately 80,000 OP units, and 867,846 newly issued shares of MAA’s Series I preferred stock.

The Merger has been accounted for using the acquisition method of accounting in accordance with ASC 805, Business Combinations, which requires, among other things, that the assets acquired and liabilities assumed be recognized at their acquisition date fair values.

For larger, portfolio style acquisitions, such as the Merger, management engages a third party valuation specialist to assist with the fair value assessment, which includes an allocation of the purchase price. Similar to management's methods, the third party generally uses cash flow analysis as well as an income approach and a market approach to determine the fair value of assets acquired. The third party specialist uses stabilized NOI and market specific capitalization and discount rates. Management reviews the inputs used by the third party specialist as well as the allocation of the purchase price provided by the third party specialist to ensure reasonableness and the procedures are performed in accordance with management's policies.

The allocation of the purchase price valuation described above required a significant amount of judgment and represents management's best estimate of the fair value as of the acquisition date. The following final purchase price allocation for the Merger was based on the Company's valuation as well as estimates and assumptions of the acquisition date fair value of the tangible and intangible assets acquired and liabilities assumed.

The following table summarizes the final purchase price allocation as of the date of the Merger (in thousands):

	December 1, 2016
Land	$	874,616
Buildings and improvements and other	3,479,483
Development and capital improvements in progress	183,881
Undeveloped land	24,200
Investment in real estate joint venture	44,435
Cash and cash equivalents	34,292
Restricted cash	3,608
Other assets	94,899
Total assets acquired	4,739,414
Notes payable	(595,609)
Accrued expenses and other liabilities	(132,906)
Total liabilities assumed, including debt	(728,515		)
Noncontrolling interests - consolidated real estate entity	(2,306		)
Total purchase price	$	4,008,593

The allocation of fair values of the assets acquired and liabilities assumed changed from the allocation reported in Note 2 to the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2016, filed with the SEC on February 24, 2017. The changes were based on information concerning the subject assets and liabilities that was not yet known at the time of the filing of the Annual Report on Form 10-K for the year ended December 31, 2016. Specifically, the purchase price allocation was updated primarily due to an adjustment to litigation reserves offset by an increase in the derivative asset value of the preferred share bifurcated call option (included in "Other assets") and real estate values.

The Company incurred total merger and integration related expenses of $20.0 million and $40.8 million for the years ended December 31, 2017and2016, respectively. The amounts were expensed as incurred and are included in the Consolidated Statements of Operations in "Merger and integration expenses". Merger related expenses primarily consisted of severance and professional costs, and integration related expenses primarily consisted of temporary systems, staffing, and facilities costs.

Earnings per share

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 years ended December 31, 2017, 2016, and 2015, MAA's basic earnings per share is computed using the two-class method, as the two-class method is the more dilutive calculation, and is presented below (dollars and shares in thousands, except per share amounts):

Earnings per OP Unit

EARNINGS PER OP UNIT OF MAALP

Basic earnings per OP 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 OP Unit. Diluted earnings per OP Unit reflects the potential dilution that could occur if securities or other contracts to issue OP Units were exercised or converted into OP Units. A reconciliation of the numerators and denominators of the basic and diluted earnings per OP Unit computations for the years ended December 31, 2017, 2016, and 2015 is presented below (dollars and units in thousands, except per unit amounts):

Stock Based Compensation [Abstract]

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]

5.STOCK BASED COMPENSATION

Overview

MAA accounts for its stock based employee compensation plans in accordance with accounting standards governing stock based compensation. These standards require an entity to measure the cost of employee services received in exchange for an award of an equity instrument based on the award's fair value on the grant date and recognize the cost over the period during which the employee is required to provide service in exchange for the award, which is generally the vesting period. Any liability awards issued are remeasured at each reporting period.

MAA’s stock compensation plans consist of a number of incentives provided to attract and retain independent directors, executive officers and key employees. Incentives are currently granted under the Amended and Restated 2013 Stock Incentive Plan, or the Stock Plan, which was approved at the 2014 annual meeting of MAA shareholders. The Stock Plan allows for the grant of restricted stock and stock options up to 625,000 shares. MAA believes that such awards better align the interests of its employees with those of its shareholders.

Compensation expense is generally recognized for service based restricted stock awards using the straight-line method over the vesting period of the shares regardless of cliff or ratable vesting distinctions. Compensation expense for market and performance based restricted stock awards is generally recognized using the accelerated amortization method with each vesting tranche valued as a separate award, with a separate vesting date, consistent with the estimated value of the award at each period end. Additionally, compensation expense is adjusted for actual forfeitures for all awards in the period that the award was forfeited. Compensation expense for stock options is generally recognized on a straight-line basis over the requisite service period. MAA presents stock compensation expense in the Consolidated Statements of Operations in "General and administrative expenses". Effective January 1, 2017, the Company adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which allows employers to make a policy election to account for forfeitures as they occur. The Company elected this option using the modified retrospective transition method, with a cumulative effect adjustment to retained earnings, and there was no material effect on the consolidated financial position or results of operations taken as a whole resulting from the reversal of previously estimated forfeitures.

Total compensation expense under the Stock Plan was approximately $10.8 million, $12.2 million and $6.9 million for the years ended December 31, 2017, 2016 and 2015, respectively. Of these amounts, total compensation expense capitalized was approximately $0.2 million, $0.7 million and $0.7 million for the years ended December 31, 2017, 2016 and 2015, respectively. As of December 31, 2017, the total unrecognized compensation expense was approximately $14.1 million. This cost is expected to be recognized over the remaining weighted average period of 1.2 years. Total cash paid for the settlement of plan shares totaled $4.8 million, $2.0 million and $1.0 million for the years ended December 31, 2017, 2016 and 2015, respectively. Information concerning grants under the Stock Plan is listed below.

Restricted Stock

In general, restricted stock is earned based on either a service condition, performance condition, or market condition, or a combination thereof, and generally vests ratably over a period from 1 year to 5 years. Service based awards are earned when the employee remains employed over the requisite service period and are valued on the grant date based upon the market price of MAA common stock on the date of grant. Market based awards are earned when MAA reaches a specified stock price or specified return on the stock price (price appreciation plus dividends) and are valued on the grant date using a Monte Carlo simulation. Performance based awards are earned when MAA reaches certain operational goals such as funds from operations, or FFO, targets and are valued based upon the market price of MAA common stock on the date of grant as well as the probability of reaching the stated targets. MAA remeasures the fair value of the performance based awards each balance sheet date with adjustments made on a cumulative basis until the award is settled and the final compensation is known. The weighted average grant date fair value per share of restricted stock awards granted during the years ended December 31, 2017, 2016 and 2015, was $84.53, $73.20 and $68.35, respectively.

The following is a summary of the key assumptions used in the valuation calculations for market based awards granted during the years ended December 31, 2017, 2016 and 2015:

	2017	2016	2015
Risk free rate	0.65% - 1.57%	0.49% - 1.27%	0.10% - 1.05%
Dividend yield	3.573%	3.634%	3.932%
Volatility	20.43% - 21.85%	18.41% - 19.45%	15.41% - 16.04%
Requisite service period	3 years	3 years	3 years

The risk free rate was based on a zero coupon risk-free rate. The minimum risk free rate was based on a period of 0.25 years for the years ended December 31, 2017, 2016 and 2015. The maximum risk free rate was based on a period of 3 years for the years ended December 31, 2017, 2016 and 2015. The dividend yield was based on the closing stock price of MAA stock on the date of grant. Volatility for MAA was obtained by using a blend of both historical and implied volatility calculations. Historical volatility was based on the standard deviation of daily total continuous returns, and implied volatility was based on the trailing month average of daily implied volatilities interpolating between the volatilities implied by stock call option contracts that were closest to the terms shown and closest to the money. The minimum volatility was based on a period of 3 years, 2 years and 1 year for the years ended December 31, 2017, 2016 and 2015, respectively. The maximum volatility was based on a period of 1 year, 1 year and 2 years for the years ended December 31, 2017, 2016 and 2015, respectively. The requisite service period is based on the criteria for the separate programs according to the vesting schedule.

A summary of the status of the nonvested restricted shares as of December 31, 2017, and the changes for the year ended December 31, 2017, is presented below:

Nonvested Shares	Shares		Weighted Average Grant-Date Fair Value
Nonvested at January 1, 2017	225,624		$	71.61
Issued	106,113		87.09
Vested	(147,687	)	70.90
Forfeited	(3,358	)	84.97
Nonvested at December 31, 2017	180,692		$	81.13

The total fair value of shares vested during the years ended December 31, 2017, 2016 and 2015 was approximately $10.5 million, $5.1 million and $2.9 million, respectively.

Stock Options

Stock options are earned when the employee remains employed over the requisite service period and vest ratably over a period from 0.3 years to 2.3 years. Stock options exercised result in new common shares being issued on the open market by the Company. The fair value of stock option awards is determined using the Black-Scholes or Monte Carlo valuation models. No stock options were granted during the years ended December 31, 2017 or December 31, 2015. During the year ended December 31, 2016, 108,198 fully vested stock options were granted with a weighted average grant date fair value of $18.08 per option as a result of options exchanged during the Merger.

The following is a summary of the key assumptions used in the Monte Carlo valuation calculations for stock options granted during the year ended December 31, 2016:

	2016
Risk free rate	0.64% - 2.63%
Dividend yield	3.81%
Volatility	21.02% - 21.57%
Expected term	1.11 - 2.11 years

The U.S. Treasury bill rate was used to represent the risk-free rate based on the expected life of the option. The current dividend yield at the time of grant was used to estimate the dividend yield over the life of the option. Volatility is based on the actual changes in the market value of MAA’s stock and is calculated using daily market value changes from the date of grant over a past period equal to the expected term of the stock options. The expected term represents an estimate of the period of time options are expected to remain outstanding.

A summary of the status of the stock options as of December 31, 2017 and the changes for the year ended December 31, 2017 is presented below:

Stock Options	Options		Weighted Average Exercise Price
Outstanding at January 1, 2017	147,282		$	76.16
Granted	—		—
Exercised	(21,006	)	64.92
Expired	(17,838	)	109.05
Outstanding at December 31, 2017	108,438		$	72.93

All options outstanding at December 31, 2017 were exercisable and had an intrinsic value of $3.0 million with a weighted average remaining term of 6.0 years. There were 21,006 options and 7,342 options exercised during the years ended December 31, 2017 and 2015, respectively. Cash received from the exercise of stock options totaled $0.4 million for both the years ended December 31, 2017 and 2015, respectively. During the year ended December 31, 2016, no cash was received from the exercise of stock options as no options were exercised.

Derivatives and Hedging Activities

Notes To Financial Statements [Abstract]

DERIVATIVES AND HEDGING ACTIVITIES

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 at December 31, 2017 and December 31, 2016, totaled $3.2 billion and $3.0 billion, respectively, and had estimated fair values of $3.3 billion and $3.1 billion (excluding prepayment penalties), respectively, as of December 31, 2017 and December 31, 2016. The carrying value of variable rate notes payable (excluding the effect of interest rate swap and cap agreements) at December 31, 2017 and December 31, 2016, totaled $1.3 billion and $1.5 billion, respectively, and had estimated fair values of $1.3 billion and $1.5 billion (excluding prepayment penalties), respectively, as of December 31, 2017 and December 31, 2016. 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 that these rates reasonably estimate current market rates. Management has determined the inputs used to value the outstanding debt fall within Level 2 of the fair value hierarchy, and therefore, the fair market valuation of debt is considered Level 2 in the fair value hierarchy.

Financial Instruments Measured at Fair Value on a Recurring Basis

The Company uses interest rate swaps and interest rate caps to add stability to interest expense and to manage its exposure to interest rate movements. 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.

The fair values of interest rate options are determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rise above the strike rate of the caps. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. The fair value of interest rate derivative contracts designated as hedging instruments recorded in "Other assets" in the accompanying Consolidated Balance Sheets was $3.6 million and $2.4 million as of December 31, 2017 and December 31, 2016, respectively. The fair value of interest rate derivative contract liabilities recorded in "Accrued expenses and other liabilities" in the accompanying Consolidated Balance Sheets was $1.3 million and $7.6 million as of December 31, 2017 and December 31, 2016, respectively.

To comply with the provisions of ASC 820, 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 has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Based on the fair value measurement guidance issued by the Financial Accounting Standard Board, 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.

The derivative asset related to the redemption feature embedded in the MAA Series I preferred stock issued in connection with Merger 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 share assuming the call option is exercised, with the value of the bifurcated call option as the difference between the two values. This 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 per share (see Note 9). The analysis uses observable market-based inputs, 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 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 or expense" in the accompanying Consolidated Statements of Operations. The embedded derivative for these preferred shares was initially recorded at a fair value of $10.8 million at the date of the Merger and as of December 31, 2016 and then subsequently adjusted to its fair value of $21.2 million at December 31, 2017. The $10.4 million increase includes a purchase price allocation adjustment of $1.6 million, which is included in the Merger's opening balance sheet, and was recorded in the first quarter of 2017, as well as $8.8 million of mark to market adjustments of non-cash income recorded to reflect the change in fair value of the derivative asset in the year ended December 31, 2017.

The Company has determined the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, and as a result, all of its derivatives held as of December 31, 2017 and December 31, 2016 were classified as Level 2 in the fair value hierarchy.

Cash Flow Hedges of Interest Rate Risk

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings and is mainly attributable to a mismatch in the underlying indices of the derivatives and the hedged interest payments made on the variable rate debt and due to the designation of acquired interest rate swaps with a non-zero fair value at inception.

Amounts reported in "Accumulated other comprehensive income" related to derivatives designated as qualifying cash flow hedges will be 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 $0.9 millionwill 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.

As of December 31, 2017, the Company had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk:

Interest Rate Derivative	Number of Instruments	Notional
Interest rate cap	1	$25,000,000
Interest rate swaps	10	$550,000,000

Credit-risk-related Contingent Features

Certain of the Company's derivative contracts contain a provision where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company's default on the indebtedness. As of December 31, 2017, the Company had not breached the provisions of these agreements. If the provisions had been breached, the Company could have been required to settle its obligations under the agreements at the termination value of $1.6 million.

Although the Company's derivative contracts are subject to master netting arrangements, which serve as credit mitigants to both the Company and its counterparties under certain situations, the Company does not net its derivative fair values or any existing rights or obligations to cash collateral in the Consolidated Balance Sheets.

Other Comprehensive Income

The Company's other comprehensive income consists entirely of gains and losses attributable to the effective portion of its cash flow hedges. The chart below reflects the change in the balance for the years ended December 31, 2017, 2016, and 2015 (in thousands):

Income Taxes [Abstract]

INCOME TAXES

INCOME TAXES

Due to the structure of MAA as a REIT and the nature of the operations of its operating properties, no provision for federal income taxes has been made at the MAA level. In addition, as MAALP is structured as a limited partnership, and its partners recognize their proportionate share of income or loss in their tax returns, no provision for federal income taxes has been made at the MAALP level. Historically, the Company has incurred certain state and local income, excise and franchise taxes. The Company has elected TRS status for certain of its corporate subsidiaries. As a result, the TRSs incur both federal and state income taxes on any taxable income after consideration of any net operating losses.

Taxable REIT Subsidiaries

The Company acquired the operations of a TRS, Colonial Properties Services, Inc., or CPSI, through an acquisition in 2013. As a result, CPSI’s tax attributes were included in MAA’s consolidated financial statements subsequent to the acquisition date. CPSI has provided property development, construction, leasing and management services for joint venture and third-party owned properties, administrative services to MAA and engaged in for-sale development activity. CPSI also owned and operated two multifamily apartment communities; however, during 2016, CPSI distributed these communities to MAALP.  The distribution resulted in a reduction of the deferred tax asset for real estate asset basis differences and the valuation allowance. In 2017, CPSI converted from a corporation to a limited liability company, which resulted in a deemed liquidation for income tax purposes. At the date of conversion, CPSI changed its name to CPSI, LLC and is no longer a TRS. CPSI, LLC is currently a disregarded entity for income tax purposes, is solely owned by MAALP and owns undeveloped land.

The Company acquired the operations of a TRS, Post Asset Management, Inc., or PAM, through the Merger in 2016. As a result, PAM’s tax attributes are included in MAA’s consolidated financial statements subsequent to the acquisition date. PAM provides third-party services to MAA and MAA’s indirectly owned properties. PAM also owns a tract of undeveloped land.

The Company generally reimburses its TRSs for payroll and other costs incurred in providing services to MAA. All intercompany transactions are eliminated in the accompanying consolidated financial statements. A TRS is an entity that is subject to federal, state and any applicable local corporate income tax without the benefit of the dividends paid deduction applicable to REITs. The Company’s TRSs did not generate any material taxable income or income tax expense for the years ended December 31, 2017, 2016 and 2015.

The TRSs use the liability method of accounting for income taxes. Deferred income tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.

As a result of the CPSI conversion to CPSI, LLC and deemed liquidation, the Company’s deferred tax asset and liability balances as of December 31, 2017 were immaterial. As of December 31, 2016, the Company had recorded net deferred tax assets relating to CPSI, which included a net operating loss, or NOL, of $58.2 million. The net deferred tax assets were fully offset by a valuation allowance as it was more likely than not the net deferred tax assets would not be realized.

For the years ended December 31, 2017 and 2016, the components of the Company’s deferred income tax assets and liabilities were as follows (in thousands):

	December 31, 2017		December 31, 2016
Deferred tax assets
Real estate asset basis differences	$	—	$	13,387
Deferred expenses	—		12,481

For the years ended December 31, 2017, 2016, and 2015, the reconciliation of income tax attributable to continuing operations for the TRSs computed at the U.S. statutory rate to the income tax provision was as follows (in thousands):

	2017			2016			2015

The Company had no reserve for uncertain tax positions for the years ended December 31, 2017, 2016 and 2015. If necessary, the Company accrues interest and penalties on unrecognized tax benefits as a component of income tax expense. For the years ended December 31, 2017, 2016 and 2015, other expenses include estimated state franchise and other taxes, including franchise taxes in North Carolina and Tennessee. The income tax expense line item shown in the Consolidated Statements of Operations represents the Texas-based margin tax for all Texas properties and federal and state taxes for PAM.

As of December 31, 2017 and 2016, the Company held federal NOL carryforwards of approximately $71.5 million for income tax purposes that expire in years 2019 to 2033. During the year ended December 31, 2016, the Company's NOL increased by $25.2 million through its acquisition of Post Properties. Utilization of any NOL carryforwards is subject to an annual limitation due to ownership change limitations provided by Section 382 of the Code and similar state provisions. The annual limitations may result in the expiration of NOL carryforwards before utilization. The Company may use these NOLs to offset all or a portion of the taxable income generated at the REIT level.

Tax years 2014 through 2017 are subject to examination by the Internal Revenue Service. No tax examination is currently in process.

For income tax purposes, dividends paid to holders of common stock primarily consist of ordinary income, return of capital, capital gains, qualified dividends and un-recaptured Section 1250 gains, or a combination thereof. For the years ended December 31, 2017, 2016 and 2015, dividends per share held for the entire year were estimated to be taxable as follows:

	2017				2016				2015
	Amount		Percentage		Amount		Percentage		Amount		Percentage
Ordinary income	$	2.79	80.2	%	$	3.28	100	%	$	3.07	99.7	%
Capital gain	0.31		8.9	%	—		—	%	—		—	%
Un-recaptured Section 1250 gain	0.38		10.9	%	—		—	%	0.01		0.3	%
	$	3.48	100.00	%	$	3.28	100.00	%	$	3.08	100.00	%

The Company designated the per share amounts above as capital gain dividends in accordance with the requirements of the Code. The difference between net income available to common shareholders for financial reporting purposes and taxable income before dividend deductions relates primarily to temporary differences such as depreciation and amortization and taxable gains on sold properties in 2017.

Merger

As discussed in Note 2, on December 1, 2016, the Company completed the Merger, whereby Post Properties merged with and into MAA completing the Parent Merger and Post LP merged with and into MAALP completing the Partnership Merger. The Company believes the Parent Merger constituted a tax free merger under Code Section 368(a). Additionally, the Company believes the Partnership Merger constituted a tax free merger under Code Section 708. As a result of the tax free merger treatment, the Merger did not result in the recognition of a gain to any security holder of MAA, Post Properties, MAALP or Post LP.

U.S. Tax Reform

In December 2017, the Tax Cuts and Jobs Act, or the Act, was enacted in the United States, requiring companies to account in 2017 for the current and future effects of the legislative changes. As REITs are pass-through entities for the purpose of U.S. federal taxation, the legislative changes created by the Act are largely not applicable to the Company. Generally, the effects to REITs resulting from the Act include a reduction in the TRS federal statutory tax rate to 21% and a one-time inclusion in REIT taxable income of foreign subsidiary earnings. As noted above, the TRS’s recognized no material taxable income in 2017 and the Company has no foreign subsidiaries. Management has concluded there was no material effect to the Company’s consolidated financial statements from either a tax or financial statement perspective as a result of the Act.

Shareholder's Equity [Abstract]

Stockholders' Equity Note Disclosure [Text Block]

SHAREHOLDERS' EQUITY OF MAA

On December 31, 2017, 113,643,166 shares of common stock of MAA and 4,191,586 OP Units (excluding the OP Units held by MAA) were issued and outstanding, representing a total of 117,834,752 shares and units. At December 31, 2016, 113,518,212 shares of common stock of MAA and 4,220,403 OP units were outstanding, representing a total of 117,738,615 shares and units. Options to purchase 108,438 shares of MAA's common stock were outstanding as of December 31, 2017 compared to 147,282 outstanding options as of December 31, 2016. During the year ended December 31, 2017, 47,956 shares of MAA's common stock were acquired from employees to satisfy minimum tax withholding obligations that arose upon vesting of restricted stock granted pursuant to approved plans. During the year ended December 31, 2016, 22,067 shares were acquired for such purposes.

Preferred Stock

As of December 31, 2017, MAA had one outstanding series of cumulative redeemable preferred stock which has the following characteristics:

Description	Outstanding Shares	Liquidation Preference(1)	Optional Redemption Date	Redemption Price (2)	Stated Dividend Yield	Approximate Dividend Rate
Series I	867,846	$50.00	10/1/2026	$50.00	8.50%	$4.25

⁽¹⁾ The total liquidation preference for the outstanding preferred stock is $43.4 million.

⁽²⁾ The redemption price is the price at which the preferred stock is redeemable, at MAA's option, for cash.

Noncontrolling Interests

Noncontrolling interests in the accompanying consolidated financial statements relates to the limited partnership interests in the Operating Partnership owned by the holders of the Class A OP Units, or Class A Units. MAA is the sole general partner of the Operating Partnership and holds all of the outstanding Class B OP Units, or Class B 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 Units or Class B Units changes the ownership percentage of both the noncontrolling interests and MAA. The issuance of Class B Units generally occurs when MAA issues common stock and the issuance proceeds are contributed to the Operating Partnership in exchange for Class B 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 Unit that were equivalent to the economic rights in respect to each share of MAA common stock. The holders of Class A Units may redeem each of their units in exchange for one share of common stock in MAA or cash, at the option of MAA. At December 31, 2017, a total of 4,191,586 Class A Units were outstanding and redeemable by the holders of the units for 4,191,586 shares of MAA common stock or approximately $421.5 million, based on the closing price of MAA’s common stock on December 31, 2017 of $100.56 per share, at MAA’s option. At December 31, 2016, a total of 4,220,403 Class A Units were outstanding and redeemable by the holders of the units for 4,220,403 shares of MAA common stock or approximately $413.3 million, based on the closing price of MAA’s common stock on December 31, 2016 of $97.92 per share, at MAA’s option. The Operating Partnership pays the same per unit distribution in respect to the Class A Units as the per share distribution MAA pays in respect to the common stock. The Operating Partnership's net income for 2017, 2016 and 2015 was allocated approximately 3.6%, 5.0% and 5.2%, respectively, to holders of Class A Units and 96.4%, 95.0% and 94.8%, respectively, to MAA as the holder of all Class B Units.

MAA further determined that the noncontrolling interest in its consolidated real estate entity totaling $2.3 million (see Note 1) met the criterion to be classified and accounted for as a component of permanent equity.

Direct Stock Purchase and Distribution Reinvestment Plan

MAA has a Dividend and Distribution Reinvestment and Share Purchase Plan, or DRSPP, pursuant to which MAA’s common shareholders have the ability to reinvest all or part of their distributions from MAA into shares of MAA’s common stock and holders of Class A Units have the ability to reinvest all or part of their distributions from the Operating Partnership into MAA’s common stock. The DRSPP also provides the opportunity to make optional cash investments in MAA's common stock of at least $250, but not more than $5,000 in any given month, free of brokerage commissions and charges. MAA, in its absolute discretion, may grant waivers to allow for optional cash payments in excess of $5,000. To fulfill its obligations under the DRSPP, MAA may either issue additional shares of common stock or repurchase common stock in the open market. MAA has registered with the SEC the offer and sale of up to 9,600,000 shares of common stock pursuant to the DRSPP. MAA may elect to sell shares under the DRSPP at up to a 5% discount. Shares of MAA's common stock totaling 9,568 in 2017, 7,906 in 2016, and 8,562 in 2015 were acquired by participants under the DRSPP. MAA did not offer a discount for optional cash purchases in 2017, 2016 or 2015.

Partners' Capital of MAA LP [Abstract]

Partners' Capital Notes Disclosure [Text Block]

PARTNERS' CAPITAL OF MAALP

OP Units

Interests in MAALP are represented by OP Units. As of December 31, 2017, there were 117,834,752 OP Units outstanding, 113,643,166 or 96.4% of which were owned by MAA, MAALP's general partner. The remaining 4,191,586 OP Units were owned by non-affiliated limited partners, or Class A Limited Partners. As of December 31, 2016, there were 117,738,615 OP Units outstanding, 113,518,212 or 96.4% of which were owned by MAA and 4,220,403 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 the Operating Partnership subject to the restrictions specifically contained within MAALP's agreement of limited partnership, or the Partnership Agreement. Unless otherwise stated in the Partnership Agreement of MAALP, 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 the Operating Partnership's assets; and distribution of Operating Partnership 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, the Operating Partnership may issue Class A Units and Class B Units. Class A Units may only be held by limited partners who are not affiliated with MAA, in its capacity as general partner of the Operating Partnership, while Class B Units may only be held by MAA, in its capacity as general partner of the Operating Partnership, and as of December 31, 2017, a total of 4,191,586 Class A Units in the Operating Partnership were held by limited partners unaffiliated with MAA, while a total of 113,643,166 Class B Units were held by MAA. In general, the limited partners do not have the power to participate in the management or control of the Operating Partnership'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 Units is also limited by the Partnership Agreement.

Net income (after allocations to preferred ownership interests) is allocated to the general partner and limited partners based on their respective ownership percentages of the Operating Partnership. Issuance or redemption of additional Class A Units or Class B Units changes the relative ownership percentage of the partners. The issuance of Class B Units generally occurs when MAA issues common stock and the proceeds from that issuance are contributed to the Operating Partnership 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, the Operating Partnership generally redeems an equal number of Class B 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 the Operating Partnership. Holders of the Class A Units may require MAA to redeem their Class A Units, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per Class A 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 Unit so redeemed.

At December 31, 2017, a total of 4,191,586 Class A Units were outstanding and redeemable for 4,191,586 shares of MAA common stock, with an approximate value of $421.5 million, based on the closing price of MAA’s common stock on December 31, 2017 of $100.56 per share. At December 31, 2016, a total of 4,220,403 Class A Units were outstanding and redeemable for 4,220,403 shares of MAA common stock, with an approximate value of $413.3 million, based on the closing price of MAA’s common stock on December 31, 2016 of $97.92 per share. The Operating Partnership pays the same per unit distribution in respect to the OP Units as the per share dividend MAA pays in respect to its common and preferred stock.

Employee Benefit Plans [Abstract]

EMPLOYEE BENEFIT PLANS

EMPLOYEE BENEFIT PLANS

The following provides details of the employee benefit plans not previously discussed in Note 5.

401(k) Savings Plans

MAA's 401(k) Savings Plan, or 401(k) Plan, is a defined contribution plan that satisfies the requirements of Section 401(a) and 401(k) of the Code. Subsequent to the Merger, eligible employees of Post Properties continued to actively participate in the Post Properties 401(k) Plan, which also is a defined contribution plan that satisfies the requirements of Section 401(a) and 401(k) of the Code. MAA's Board of Directors has the discretion to approve matching contributions to these plans. MAA's contributions to these plans were approximately $2.8 million, $2.0 million and $1.0 million for the years ended December 31, 2017, 2016 and 2015, respectively.

Non-Qualified Deferred Compensation Retirement Plan

MAA has adopted a non-qualified deferred compensation retirement plan for certain selected executive employees. Under the terms of the plan, employees may elect to defer a percentage of the compensation and bonus, and MAA may, but is not obligated to, match a portion of their salary deferral. MAA’s match to this plan for the years ended December 31, 2017, 2016 and 2015 was approximately $249,000, $96,000 and $106,000, respectively.

Non-Qualified Deferred Compensation Plan for Outside Company Directors

In 1998, MAA established the Non-Qualified Deferred Compensation Plan for Outside Company Directors, or the Directors Deferred Compensation Plan, which allows non-employee directors to defer their director fees by having the fees held by MAA as shares of MAA's common stock. Directors can also choose to have their annual restricted stock grants issued into the Directors Deferred Compensation Plan. Amounts deferred through the Directors Deferred Compensation Plan are distributed to the directors in two annual installments beginning in the first 90 days of the year following the director’s departure from the board. Participating directors may choose to have the amount issued to them in shares of MAA's common stock or paid to them as cash at the market value of MAA's common stock as of the end of the year the director ceases to serve on the board.

For the years ended December 31, 2017, 2016 and 2015, directors deferred 12,293 shares, 10,166 shares and 8,466 shares of common stock, respectively, with weighted-average grant date fair values of $101.34, $97.99 and $78.62, respectively, into the Directors Deferred Compensation Plan. The shares of common stock held in the Directors Deferred Compensation Plan are classified outside of permanent equity in redeemable stock with changes in redemption amount recorded immediately to retained earnings because the directors have redemption rights not solely within the control of MAA. Additionally, any shares that become mandatorily redeemable because a departed director has elected to receive a cash payout are recorded as a liability. MAA did not record a liability related to mandatorily redeemable shares for the years ended December 31, 2017, 2016 and 2015.

Employee Stock Ownership Plan

MAA’s Employee Stock Ownership Plan, or ESOP, is a non-contributory stock bonus plan that satisfies the requirements of Section 401 (a) of the Code. On December 31, 2010, the ESOP was frozen by amendment, whereby effective January 1, 2011, no additional employees became eligible for the plan, no additional contributions were made to the ESOP, and all Participants with an account balance under the ESOP became 100% vested. The Company did not contribute to the ESOP during 2017, 2016 or 2015. As of December 31, 2017, there were 145,598 shares outstanding with a fair value of $14.6 million.

Land and Equipment Leases

The Company has a ground lease expiring in 2074 related to one of its apartment communities acquired in the Merger. This lease contains stated rent increases that generally compensate for the impact of inflation.  The Company also has office, equipment and other operating leases.  Future minimum lease payments for non-cancelable land, equipment and other operating leases at December 31, 2017, were as follows (in thousands):

Legal Proceedings

In September 2010, the United States Department of Justice, or DOJ, filed suit against Post Properties (and by virtue of the Merger, MAA) in the United States District Court for the District of Columbia alleging that certain of Post Properties’ apartments violated accessibility requirements of the Fair Housing Act, or FHA. and the Americans with Disabilities Act of 1990, or ADA. The DOJ is seeking, among other things, an injunction against MAA, requiring MAA to retrofit the properties and comply with FHA and ADA standards in future design and construction, as well as monetary damages and civil penalties. No trial date has been set.

In December 2017, a non-profit civil rights organization filed suit against MAA and the Operating Partnership in the United States District Court for the District of Columbia. The suit alleges the Company maintained and enforced a criminal records screening policy at certain of its apartment communities, all of which are apartments acquired from Post Properties in the Merger, which violates the FHA. The suit seeks injunctive relief, actual and punitive damages and attorneys' fees and costs.

The Company is subject to various other legal proceedings and claims that arise in the ordinary course of our 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 such matters, either individually or in the aggregate, will have a material adverse effect on the Company's financial position, results of operations or cash flows.

As of December 31, 2017 and December 31, 2016, the Company's accrual for loss contingencies, including the legal proceedings referenced above, was $32.1 million and $42.1 million in the aggregate, respectively. The loss contingencies are presented in "Accrued expenses and other liabilities" in the accompanying Consolidated Balance Sheets.

RELATED PARTY TRANSACTIONS

The Company holds investments in unconsolidated affiliates accounted for under the equity method of accounting. All significant intercompany transactions were eliminated in the accompanying consolidated financial statements.

The cash management of the Company is managed by the Operating Partnership. In general, cash receipts are remitted to the Operating Partnership and all cash disbursements are funded by the Operating Partnership. As a result of these transactions, the Operating Partnership had a payable to MAA, its general partner, of $19,000 at each of the years ended December 31, 2017, and 2016. The Partnership Agreement does not require the due to/due from balance to be settled in cash until liquidation of the Operating Partnership, and therefore, there is no regular settlement schedule for such amounts.

Notes To Financial Statements [Abstract]

SEGMENT INFORMATION

SEGMENT INFORMATION

As of December 31, 2017, the Company owned or had an ownership interest in 302 multifamily apartment communities in 17 different states and the District of Columbia from which it derived all significant sources of earnings and operating cash flows. Management evaluates performance and determines resource allocations of each of the apartment communities on a Large Market Same Store, Secondary Market 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 three reportable operating segments for the Company:

• Large Market Same Store communities are generally communities in markets with a population of at least 1 million and at least 1% of the total public multifamily REIT units that the Company has owned and has been stabilized for at least a full 12 months.

• Secondary Market Same Store communities are generally communities in markets with populations of more than 1 million but less than 1% of the total public multifamily REIT units or markets with populations of less than 1 million that the Company has owned and has been stabilized for at least a full 12 months.

• Non-Same Store and Other includes recent acquisitions, communities in development or lease-up, communities that have been identified for disposition, and communities that have undergone a significant casualty loss. Also included in non-same store communities are non-multifamily activities.

On the first day of each calendar year, the Company determines the composition of its same store operating segments for that year as well as adjust 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 it 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 Company utilizes NOI in evaluating the performance of the 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 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 related to property operating performance.

All properties acquired as a result of the Merger have been placed in the Non-Same Store and Other operating segment, as the properties were recent acquisitions and had not been owned and stabilized for at least 12 months as of the first day of the applicable calendar year.

Revenues and NOI for each reportable segment for the years ended December 31, 2017, 2016 and 2015 were as follows (in thousands):

⁽¹⁾  Encumbered by $80.0 million Fannie Mae facility, with $80.0 million available and outstanding with a variable interest rate of 1.8% on which there exists one interest rate cap for $25 million at a rate of 4.50% at December 31, 2017.

⁽²⁾  Encumbered by a $125.2 million loan with a fixed interest rate of 5.08% which matures on June 10, 2021.

⁽³⁾  The aggregate cost for federal income tax purposes was approximately $10.8 billion at December 31, 2017. The aggregate cost for book purposes exceeds the total gross amount of real estate assets for federal income tax purposes, principally due to purchase accounting adjustments recorded under accounting principles generally accepted in the United States of America.

Accounting Policies [Abstract]

Basis of Presentation and Principles of Consolidation

Basis of Presentation and Principles of Consolidation

The accompanying 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 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 approximately 92.5% to 100% of all consolidated subsidiaries, including the Operating Partnership. The 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, 92.5% to 100% of all consolidated subsidiaries. In management's opinion, all adjustments necessary for a fair presentation of the 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, since 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 "Investment in Unconsolidated Affiliates" below).

Use of Estimates

Use of Estimates

Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses to prepare these financial statements and notes in conformity with GAAP. Actual results could differ from those estimates.

Revenue Recognition and Real Estate Sales

Revenue Recognition and Real Estate Sales Gain Recognition

The Company primarily leases multifamily residential apartments under operating leases generally with terms of one year or less, which are recorded as operating leases. Rental lease revenues are recognized in accordance with Accounting Standards Codification, or ASC, 840, Leases, using a method that represents a straight-line basis over the term of the lease. Rental income represents gross market rent less adjustments for concessions, vacancy loss and bad debt. Other non-lease revenues are recognized in accordance with ASC, 605, Revenue Recognition, when such sources of revenue are earned, and the amounts are fixed and determinable. The Company records gains and losses on real estate sales in accordance with accounting standards governing the sale of real estate. For sale transactions meeting the requirements for the full accrual method, the Company removes the assets and liabilities from its Consolidated Balance Sheets and recognizes the gain or loss in the period the transaction closes.

Rental Costs

Rental Costs

Costs associated with rental activities are expensed as incurred and include advertising expenses, which were approximately$18.8 million, $13.0 million, and $13.5 million for the years ended December 31, 2017, 2016, and 2015, respectively.

Real Estate Assets and Depreciation and Amortization

Real Estate Assets and Depreciation and Amortization

Real estate assets are carried at depreciated cost and consist of land, buildings and improvements and other and development and capital improvements in progress (see "Development Costs" below). Repairs and maintenance costs are expensed as incurred, while significant improvements, renovations, and recurring capital replacements are capitalized and depreciated over their estimated useful lives. Recurring capital replacements typically include scheduled carpet replacement, new roofs, HVAC units, plumbing, concrete, masonry and other paving, pools and various exterior building improvements. In addition to these costs, the Company also capitalizes salary costs directly identifiable with renovation work. These expenditures extend the useful life of the property and increase the property’s fair market value. The cost of interior painting, vinyl flooring and blinds are expensed as incurred.

Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets

Development Costs

Development Costs

Development projects and the related carrying costs, including interest, property taxes, insurance and allocated direct development salary cost during the construction period, are capitalized and reported in the accompanying Consolidated Balance Sheets as "Development and capital improvements in progress" during the construction period. Interest is capitalized in accordance with accounting standards governing the capitalization of interest. Upon completion and certification for occupancy of individual buildings or floors within a development, amounts representing the completed portion of total estimated development costs for the project are transferred to "Land" and "Buildings and improvements and other" as real estate held for investment. Capitalization of interest, property taxes, insurance and allocated direct development salary costs cease upon the transfer. The assets are depreciated over their estimated useful lives. Total capitalized costs (including capitalized interest, salaries and real estate taxes) during the years ended December 31,2017, 2016 and 2015 was approximately $11.0 million, $2.7 million and $2.3 million, respectively. Certain costs associated with the lease-up of development projects, including cost of model units, furnishings, signs and grand openings, are capitalized and amortized over their respective estimated useful lives. All other costs relating to renting development projects are expensed as incurred.

Acquisition of Real Estate Assets

Acquisition of Real Estate Assets

The Company adopted ASU 2017-01, Clarifying the Definition of a Business (Topic 805), effective January 1, 2017. Subsequent to the adoption of ASU 2017-01, most acquisitions of operating properties qualify as asset acquisitions rather than business combinations. Accordingly, the cost of the real estate acquired is allocated to the acquired tangible assets, consisting of land, buildings and improvements and other, and identified intangible assets, consisting of the value of in-place leases and other contracts, on a relative fair value basis.

The purchase price of an acquired property is allocated based on the relative fair value of the individual components as a proportion of the total assets acquired. The Company allocates the cost of the tangible assets of an acquired property by valuing the building as if it were vacant, based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a building using methods similar to those used by independent appraisers. These methods include using stabilized net operating income, or NOI, and market specific capitalization and discount rates. In allocating the cost of identified intangible assets of an acquired property, the in-place leases are valued based on current rent rates and time and cost to lease a unit. Management concluded that the residential leases acquired in connection with each of its property acquisitions approximate at-market rates since the residential lease terms generally do not extend beyond one year.

For residential leases, the fair value of the in-place leases and resident relationships is amortized over 6 months, which represents the estimated remaining term of the tenant leases. For commercial leases, the fair value of in-place leases and resident relationships is amortized over the remaining term of the commercial leases. The amount of these lease intangibles included in "Other assets" totaled $11.2 million and $42.4 million as of December 31, 2017, and 2016, respectively. Accumulated amortization for these leases totaled $4.1 million and $7.3 million as of December 31, 2017 and 2016, respectively. The amortization of these intangibles recorded as "Depreciation and amortization expense" was $29.4 million, $8.7 million, and $5.0 million for the years ended December 31, 2017, 2016, and 2015, respectively. The estimated aggregate future amortization expense of in-place leases is approximately $2.8 million, $1.6 million, $0.8 million, $0.5 million, and $0.3 million for the years ended December 31, 2018, 2019, 2020, 2021, and 2022, respectively.

As a result of the adoption of ASU 2017-01, the Company believes most acquisitions of operating properties will qualify as asset acquisitions and associated transaction costs will be capitalized. Acquisition costs include appraisal fees, title fees, broker fees, and other legal costs to acquire the property.

Impairment of Long-lived Assets, including Goodwill

Impairment of Long-lived Assets

The Company accounts for long-lived assets in accordance with the provisions of accounting standards for the impairment or disposal of long-lived assets. Management periodically evaluates long-lived assets, including investments in real estate, for indicators that would suggest that the carrying amount of the assets may not be recoverable. The judgments regarding the existence of such indicators are based on factors such as operating performance, market conditions and legal factors. Long-lived assets, such as real estate assets, equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the Consolidated Balance Sheets and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group or a property classified as held for sale are presented separately in the appropriate asset and liability sections of the Consolidated Balance Sheets.

Loss Contingencies

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. 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 may 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 expected ultimately 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.

Undeveloped Land

Undeveloped Land

Undeveloped land includes sites intended for future multifamily developments, sites for future commercial development and sites intended for residential use, which are carried at the lower of cost or fair value in accordance with GAAP and any costs incurred prior to commencement of pre-development activities are expensed as incurred.

Investment in Real Estate Joint Ventures

Investment in Unconsolidated Affiliates

Immediately prior to the effective date of the Merger, Post Properties was an investor, together with other institutional investors, in a limited liability company, or the Apartment LLC, that indirectly owned one apartment community, Post Massachusetts Avenue, located in Washington, D.C.  Post Properties owned a 35.0% equity interest in the unconsolidated joint venture, which was retained by MAA immediately following the close of the Merger and as of December 31, 2017. The Company provides property and asset management services to the Apartment LLC for which it earns fees. The joint venture was determined to be a VIE, but the Company is not designated as a primary beneficiary. As a result, the Company accounts for its investment in the Apartment LLC using the equity method of accounting as the Company is able to exert significant influence over the joint venture but does not have a controlling interest. At December 31, 2017, the Company's investment in the Apartment LLC totaled $45.0 million.  

During September 2017, a subsidiary of the Operating Partnership entered into a limited partnership together with a general partner and other limited partners to form Real Estate Technology Ventures, L.P. The Operating Partnership indirectly owns 31.0% of the limited partnership. The limited partnership was determined to be a VIE, but the Company is not designated as a primary beneficiary. As a result, the Company accounts for its investment in the limited partnership using the equity method of accounting as the investment is considered more than minor. At December 31, 2017, the Company's investment in the limited partnership totaled $1.5 million. The Company is committed to make additional capital contributions totaling $13.5 million if and when called by the general partner of the limited partnership prior to September 2022.

Cash and Cash Equivalents

Cash and Cash Equivalents

Investments in money market accounts and certificates of deposit with original maturities of three months or less are considered to be cash equivalents.

Restricted Cash

Restricted Cash

Restricted cash consists of security deposits required to be held separately, escrow deposits held by lenders for property taxes, insurance, debt service, and replacement reserves, and exchanges under Section 1031(b) of the Internal Revenue Code of 1986, as amended, or the Code. Section 1031(b) exchanges are treated as investing activities in the Consolidated Statements of Cash Flows.

Other Assets

Other Assets

Other assets consist primarily of receivables and deposits from residents, the value of derivative contracts, deferred rental concessions, deferred financing costs relating to lines of credit, and other prepaid expenses. Also included in other assets are the fair market value of in-place leases and resident relationships, net of accumulated amortization

Accrued Expenses and Other Liabilities

Accrued Expenses and Other Liabilities

Accrued expenses consist of accrued dividends payable, accrued real estate taxes, accrued interest payable, accrued loss contingencies, accounts payable, fair market value of interest rate swaps (see Note 7), security deposits not related to restricted cash, other accrued expenses, and unearned income. Significant accruals include accrued dividends payable of $108.7 million and $102.4 million at December 31, 2017 and 2016, respectively; accrued real estate taxes of $99.6 million and $97.6 million at December 31, 2017 and 2016, respectively; unearned income of $40.8 million and $39.4 million at December 31, 2017 and 2016, respectively; accrued loss contingencies of $32.1 million and $42.1 million at December 31, 2017 and 2016, respectively; security deposits of $19.1 million and $18.8 million at December 31, 2017 and 2016, respectively; and accrued interest payable of $18.1 million and $19.1 million at December 31, 2017 and 2016, respectively.

Self Insurance

Self-Insurance

The Company is self-insured for workers' compensation claims up to $500,000 and for general liability claims up to $100,000. The Company accrues for expected liabilities less than these amounts based on third party actuarial estimates of ultimate losses.

Income Taxes

Income Taxes

Fair value of derivative financial instruments

Fair Value Measurements

The Company applies the guidance in ASC Topic 820, Fair Value Measurements and Disclosures, to the valuation of real estate assets recorded at fair value, if any; 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 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.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

The following table provides a brief description of recent accounting pronouncements that could have a material effect on the Company's consolidated financial statements:

Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
ASU 2014-09, Revenue from Contracts with Customers	The ASU establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services as outlined in a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied. Income from lease contracts is specifically excluded from this ASU.	The ASU is effective for annual reporting periods beginning after December 15, 2017 Early adoption is permitted.	The amendments may be applied using the full retrospective transition method or by using the modified retrospective transition method with a cumulative effect recognized as of the date of initial application. The Company adopted ASU 2014-09 effective January 1, 2018, using the modified retrospective approach. The majority of the Company's revenue is derived from real estate lease contracts, which falls outside the scope of the ASU. The Company has completed its analysis of non-lease related revenues. The adoption of the ASU does not have a material impact on the Company's consolidated financial statements or to the Company's internal accounting policies. The guidance does require additional disclosures regarding the nature and timing of the Company's revenue transactions upon adoption.
ASU 2016-02, Leases	The ASU amends existing accounting standards for lease accounting and establishes the principles for lease accounting for both the lessee and lessor. The amendment requires an entity to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendment also requires certain quantitative and qualitative disclosures about leasing arrangements.	The ASU is effective for annual reporting periods beginning after December 15, 2018; however, early adoption is permitted.	The standard must be adopted using a modified retrospective transition and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. Management is currently evaluating the impact the standard will have on the consolidated financial statements and related disclosures upon adoption. The Company plans to adopt the ASU effective January 1, 2019.

ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)	The ASU clarifies how several specific cash receipts and cash payments are to be presented and classified on the statement of cash flows, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration made after a business combination, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of predominance principle.	The ASU is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted.	Each amendment in this standard must be applied prospectively, retrospectively, or as of the beginning of the earliest comparative period presented in the year of adoption, depending on the type of amendment. The Company adopted ASU 2016-15 as of January 1, 2018. Management has determined three of the eight transactions in the update are relevant to MAA and its cash flows, including: 1) debt prepayment or debt extinguishment costs, 2) proceeds from the settlement of insurance claims and 3) distributions received from equity method investees. Management performed an analysis and determined only the change in classification of debt prepayment or debt extinguishment costs, which is currently reported in operating activities, will have a significant impact on the consolidated statements of cash flows. Upon adoption in the first quarter of 2018, $1.7 million of cash outflows for debt prepayment or extinguishment costs currently reported in net cash provided by operating activities for the year ended December 31, 2017, will be re-classified to and reported in net cash used in financing activities.
ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (A Consensus of the FASB Emerging Issues Task Force)	The ASU requires restricted cash to be presented with cash and cash equivalents when reconciling the beginning and ending amounts in the consolidated statements of cash flows.	The ASU is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted.	The update should be applied retrospectively to each period presented. The Company adopted ASU 2016-18 as of January 1, 2018. The Company currently reports the change in restricted cash within the operating and investing activities in the consolidated statements of cash flows. Upon adoption in the first quarter of 2018, cash and cash equivalents reported in the consolidated statements of cash flows for the year ended December 31, 2017 will increase by approximately $78.1 million to reflect the restricted cash balances. Additionally, net cash used in investing activities will decrease by $10.6 million for the year ended December 31, 2017.
ASU 2017-12, Derivatives and Hedging (Topic 815)	The ASU clarifies hedge accounting requirements, improves disclosure of hedging arrangements, and better aligns risk management activities and financial reporting for hedging relationships.	The ASU is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted.	The standard should be adopted using a modified retrospective approach. This adoption method will require the Company to recognize the cumulative effect of initially applying ASU 2017-12 as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings. The Company elected to early adopt the ASU as of January 1, 2018. Management has completed its assessment of the impact the standard has on the Company's consolidated financial statements and related disclosures. Adoption of the ASU does not have a material impact on the consolidated financial statements or the Company's internal accounting policies.

Derivatives, Policy [Policy Text Block]

Derivative Financial Instruments

The Company utilizes certain derivative financial instruments, primarily interest rate swaps and interest rate caps, during the normal course of business to manage, or hedge, the interest rate risk associated with our variable rate debt or as hedges in anticipation of future debt transactions to manage well-defined interest rate risk associated with the transaction.

Additionally, the 867,846 shares of MAA's Series I preferred stock issued as consideration in the Merger are redeemable, at the Company's option, beginning on October 1, 2026, at the redemption price of $50 per share (see Note 9). The redemption feature embedded in the preferred stock was evaluated in accordance with ASC 815, Derivatives and Hedging, and the Company determined that it was required to bifurcate the value associated with the redemption feature from the host instrument, the perpetual preferred shares. The redemption feature embedded in the MAA Series I preferred stock is reported as a derivative asset in "Other assets" in the accompanying Consolidated Balance Sheets at its fair value and will be adjusted to its fair value at each reporting date, with a corresponding adjustment to "Other non-operating income (expense)".

Earnings per share of the trust [Abstract]

Schedule of Calculation of Numerator and Denominator in Earnings Per Share [Table Text Block]

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 years ended December 31, 2017, 2016, and 2015, MAA's basic earnings per share is computed using the two-class method, as the two-class method is the more dilutive calculation, and is presented below (dollars and shares in thousands, except per share amounts):
