Explanatory Note

This periodic report on Form 10-Q, or this Report, combines the quarterly reports for the quarter ended September 30, 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 its sole general partner. Mid-America Apartment Communities, Inc. and its 96.4% owned subsidiary, Mid-America Apartments, L.P., are both required to file periodic reports under the Securities Exchange Act of 1934, as amended.

Unless the context otherwise requires, all references in this Report to "MAA" refer only to Mid-America Apartment Communities, Inc., and not to 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 and "shareholders" means the holders of shares of MAA’s common stock. 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 September 30, 2017, MAA owned 113,627,014 OP Units (or 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 periodic reports of MAA and the Operating Partnership, including the notes to the condensed consolidated financial statements, into this Report results in the following benefits:


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


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


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

MAA is a multifamily focused, self-administered and self-managed real estate investment trust, or REIT. Management operates MAA and the Operating Partnership as one business. The management of the Company is comprised of individuals who are officers of MAA and employees of the Operating Partnership. 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; 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 our 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 partnership units.

The presentation of MAA's shareholders' equity and the Operating Partnership's capital is the principal area 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 interests, preferred units, treasury shares, accumulated other comprehensive income and redeemable common units. The Operating Partnership's capital may include common capital and preferred capital of the general partner (MAA), limited partners' common capital and preferred capital, limited partners' noncontrolling interests, 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 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 Report includes sections that separately present and discuss areas that are materially different between MAA and the Operating Partnership, including:


•	the Condensed Consolidated Financial Statements in Item 1 of this Report;


•	certain accompanying notes to the Condensed Consolidated Financial Statements, including Note 3 - Earnings per Common Share of MAA and Note 4 - Earnings per OP Unit of MAALP; Note 5 - MAA Equity and Note 6 - MAALP Capital; and Note 10 - Shareholders' Equity of MAA and Note 11 - Partners' Capital of MAALP; and


•	the certifications of the Chief Executive Officer and Chief Financial Officer of MAA included as Exhibits 31 and 32 to this Report.

In the sections that combine disclosure 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.

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

Notes to Condensed Consolidated Financial Statements

September 30, 2017 and 2016

(Unaudited)

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

Unless the context otherwise requires, all references 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 to "MAA" refer only to Mid-America Apartment Communities, Inc. and not any of its consolidated subsidiaries. Unless the context otherwise requires, all 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 "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".

We believe combining the notes to the condensed 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 report instead of two separate reports

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. 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 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 our 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 our 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 is the principal area of difference between the condensed consolidated financial statements of MAA and those of the Operating Partnership. MAA's shareholders' equity may include shares of preferred stock, shares of common stock, additional paid-in capital, cumulative earnings, cumulative distributions, noncontrolling interests, preferred units, treasury shares, accumulated other comprehensive income and redeemable common units. The Operating Partnership's capital may include common capital and preferred capital of the general partner (MAA), limited partners' preferred capital, limited partners' noncontrolling interests, 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 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. We refer to the Parent Merger, together with the Partnership Merger, as the Merger in this Report. 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 we refer 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 we refer 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.

As of September 30, 2017, we owned and operated 302 apartment communities, comprising 99,612 apartment units located in 17 states, through the Operating Partnership. As of September 30, 2017, we also owned a 35.0% interest in an unconsolidated real estate joint venture and a 32.0% interest in an unconsolidated limited partnership. As of September 30, 2017, we had five development communities under construction totaling 1,434 apartment units. Total expected costs for the development projects are $305.0 million, of which $235.3 million has been incurred through September 30, 2017. We expect to complete construction on two projects by the fourth quarter of 2017, 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 our multifamily properties include retail components with approximately 600,000 square feet of gross leasable area. We also have four wholly-owned commercial properties, which we acquired through the Merger, with approximately 232,000 square feet of combined gross leasable area.

Basis of Presentation and Principles of Consolidation

The accompanying Condensed Consolidated Financial Statements have been prepared by our management in accordance with United States generally accepted accounting principles, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or the SEC. The Condensed Consolidated Financial Statements of MAA presented herein include the accounts of MAA, the Operating Partnership, and all other subsidiaries in which MAA has a controlling financial interest. MAA owns approximately 92.5% to 100% of all consolidated subsidiaries, including the Operating Partnership. The Condensed Consolidated Financial Statements of MAALP presented herein include the accounts of MAALP and all other subsidiaries in which MAALP has a controlling financial interest. MAALP owns, directly or indirectly, 92.5% to 100% of all consolidated subsidiaries. In our opinion, all adjustments necessary for a fair presentation of the Condensed Consolidated Financial Statements have been included, and all such adjustments were of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation.

We invest 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. We consolidate all VIEs for which we are the primary beneficiary and use the equity method to account for investments that qualify as VIEs but for which we are not the primary beneficiary. In determining whether we are the primary beneficiary of a VIE, we consider 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.

We use the equity method of accounting for our investments in entities for which we exercise significant influence, but do not have the ability to exercise control. The factors considered in determining that we do not have the ability to exercise control include ownership of voting interests and participatory rights of investors (see "Investment in Unconsolidated Real Estate Joint Ventures" below).

Noncontrolling Interests

At September 30, 2017, the Company had two types of noncontrolling interests, (1) noncontrolling interests related to the common unitholders of the Operating Partnership (see Note 11) and (2) noncontrolling interests related to its consolidated real estate entities (see "Investment in Consolidated Real Estate Joint Ventures" below).

Investment in Unconsolidated Joint Ventures

Immediately prior to the effective date of the Merger, Post Properties together with other institutional investors, in a limited liability company, or the Apartment LLC, owned one apartment community, Post Massachusetts Avenue, located in Washington, D.C. Post Properties had a 35.0% equity interest in this unconsolidated joint venture, which we retained immediately following the effectiveness of the Merger and as of September 30, 2017. We provide property and asset management services to the Apartment LLC for which we earn fees.

This joint venture was determined to be a VIE, but we are not designated as a primary beneficiary. As a result, we account for our investment in the Apartment LLC using the equity method of accounting, as we are able to exert significant influence, but do not have a controlling interest in this joint venture. At September 30, 2017, our investment in the Apartment LLC totaled $45.1 million.

During September 2017, MAA entered into a limited partnership together with a general partner and other limited partners to form Real Estate Technology Ventures, L.P. MAA's equity interest in the partnership is 32.0%, which is considered more than minor. This joint venture was determined to be a VIE, but we are not designated as a primary beneficiary. Therefore, we account for our investment in the limited partnership using the equity method of accounting, as we are able to exert significant influence over the partnership but do not have a controlling interest in this joint venture. At September 30, 2017, our investment in the limited partnership totaled $0.8 million, and we are committed to make additional capital contributions totaling $14.2 million over the next five years from the date of the initial capital contribution.

Investment in Consolidated Real Estate Joint Ventures

In 2015, Post Properties entered into a joint venture arrangement with a private real estate company to develop, construct and operate a 358-unit apartment community in Denver, Colorado. At September 30, 2017, we owned a 92.5% equity interest in the consolidated joint venture. In 2015, this 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 we will continue to manage the community upon its completion. This joint venture was determined to be a VIE with us designated as the primary beneficiary. As a result, the accounts of the joint venture are consolidated by us. At September 30, 2017, our consolidated assets, liabilities and equity included construction in progress of $60.3 million, land of $14.5 million, and accounts payable and accrued expenses of $6.2 million.

Assets Held for Sale

During September 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; however, the sale is not expected to close until the fourth quarter of 2017. As a result, the assets and liabilities associated with the land parcel were presented as held for sale in the Condensed Consolidated Balance Sheets.

2. Business Combination

On December 1, 2016, we completed the Merger. As part of the Merger, we acquired 61 wholly-owned apartment communities comprising 24,138 apartment 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 Merger date. Post Properties had operations in ten markets across the United States. In addition to the apartment communities, we 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 our Consolidated Financial Statements from the closing date, December 1, 2016, 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 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 pay off a $300.0 million Post LP unsecured term loan and a $162.0 million Post LP line of credit, both outstanding from Wells Fargo. 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 $77.00 per share, which included a $14.24 per share bifurcated call option (See Notes 8 & 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, we issued approximately 38.0 million shares of MAA common stock,

approximately 80,000 OP Units, and 867,846 newly issued shares of MAA Series I preferred stock.

The Merger has been accounted for using the acquisition method of accounting in accordance with Accounting Standards Codification, or 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, like 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 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 uses stabilized net operating income, or 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 to ensure reasonableness and that the procedures are performed in accordance with management's policy. The allocation of the purchase price is based on management’s assessment, which may differ as more information becomes available. Subsequent adjustments made to the purchase price allocation, if any, are made within the allocation period, which typically does not exceed one year.

The allocation of the purchase price described above requires a significant amount of judgment and represents management's best estimate of the fair value as of the acquisition date. The following preliminary purchase price allocation for the Merger reflects updates primarily to an adjustment to litigation reserves offset by increased derivative asset values on the preferred share bifurcated call option (included in "Other assets") and real estate asset values from our December 31, 2016 estimates. Such preliminary purchase price allocation was based on our valuation as well as estimates and assumptions of the acquisition date fair value of the tangible and intangible assets acquired and liabilities assumed.

The purchase price was allocated as follows (in thousands):



Land	$	875,294
Buildings and improvements	3,397,342
Furniture, fixtures and equipment	81,243
Development and capital improvements in progress	183,881
Undeveloped land	24,200
Commercial properties, net	3,610
Investment in real estate joint venture	44,435
Lease intangible assets	53,192
Cash and cash equivalents	34,292
Restricted cash	3,608
Deferred costs and other assets, excluding lease intangible assets	41,803
Total assets acquired	4,742,900

Notes payable	(595,609)
Fair market value of interest rate swaps	(2,118)
Lease intangible liabilities	(1,661)
Accounts payable, accrued expenses, and other liabilities	(132,613)
Total liabilities assumed, including debt	(732,001		)

Noncontrolling interests - consolidated real estate entity	(2,306		)

Total purchase price	$	4,008,593

The purchase price accounting reflected in the accompanying financial statements is based upon estimates and assumptions that are subject to change within the measurement period, pursuant to ASC 805. See Note 12 for loss contingencies identified, measured, and included in "Accounts payable, accrued expenses, and other liabilities" in the allocation above. We have preliminarily completed our valuation procedures. Adjustments may still occur as the valuation and revised preliminary purchase allocation is finalized in areas such as real estate related assets and liabilities, equity investments, litigation reserves, debt and debt related instruments, and certain other acquired assets and liabilities assumed. We will complete our purchase price allocation during the fourth quarter of 2017.

We incurred Merger and integration related expenses of $14.5 million for the nine months ended September 30, 2017. These amounts were expensed as incurred and are included in the Condensed Consolidated Statements of Operations in the items titled "Merger related expenses", primarily consisting of severance and professional costs, and "Integration related expenses", primarily consisting 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 for MAA common shareholders by the weighted average number of shares outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per share. 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 our 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 they are dilutive to earnings per share. For the three and nine months ended September 30, 2017 and 2016, MAA's basic earnings per share was computed using the two-class method, and MAA's diluted earnings per share was computed using the more dilutive of the treasury stock method or two-class method, as presented below:

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 three and nine months ended September 30, 2017 and 2016 is presented below:

7. Borrowings

The weighted average effective interest rate at September 30, 2017 and December 31, 2016 for the $4.5 billion of debt outstanding was 3.5% at both balance sheet dates. Our debt consists of an unsecured revolving credit facility, unsecured term loans, senior unsecured notes, a secured credit facility with the Federal National Mortgage Association, or the Fannie Mae Facility, and secured property mortgages. We utilize fixed rate borrowings, interest rate swaps, and interest rate caps to manage our current and future interest rate risk.

At September 30, 2017, we had $2.8 billion of senior unsecured notes and unsecured term loans fixed at an average interest rate of 3.8%, $300.0 million of variable rate unsecured term loans with an average interest rate of 2.2%, and a $1.0 billion unsecured variable rate revolving credit facility with an average interest rate of 2.1% with $250.0 million borrowed at September 30, 2017. Additionally, we had $110.0 million of secured variable rate debt outstanding at an average interest rate of 1.7% and $50.0 million of capped secured variable rate debt at an average interest rate of 1.7%. The interest rate on all other secured debt, totaling $950.0 million, was hedged or fixed at an average interest rate of 4.0%.

Unsecured Revolving Credit Facility

We maintain 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 2.14%. The KeyBank Facility expires in April 2020 with an option to extend for an additional six months. At September 30, 2017, we had $250.0 million actually borrowed under this facility, and another approximately $2.5 million of the facility used to support letters of credit.

Unsecured Term Loans

We also maintain four term loans with a syndicate of banks, one led by KeyBank National Association, or KeyBank, two by Wells Fargo Bank, N.A., or Wells Fargo, and one by U.S. Bank National Association, or U.S. Bank, respectively. The KeyBank term loan has a balance of $150.0 million, matures in 2021, and has a variable interest rate of LIBOR plus a spread of 0.90% to 1.75% based on our credit ratings. The Wells Fargo term loans have balances of $250.0 million and $300.0 million, respectively, mature in 2018 and 2022, respectively, and have variable interest rates of LIBOR plus spreads of 0.90% to 1.90%% and 0.90% to 1.75%%, respectively, based on our credit ratings. The U.S. Bank term loan has a balance of $150.0 million, matures in 2020, and has a variable interest rate of LIBOR plus a spread of 0.90% to 1.90% based on our credit ratings.

Senior Unsecured Notes

As of September 30, 2017, we had approximately $2.0 billion (face value) of publicly issued notes and $310 million of private placement notes. These senior unsecured notes had maturities at issuance ranging from five to twelve years, averaging 7.1 years remaining until maturity as of September 30, 2017.

On May 9, 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 Condensed Consolidated Balance Sheet. In connection with the issuance of the 2027 Notes, we cash settled $300.0 million in forward interest rate swap agreements, entered into during the first two quarters in the year to effectively lock the interest rate on the planned transaction, which produced an effective interest rate of 3.68% over the ten year life of the 2027 Notes.

On July 17, 2017, we paid off $150.0 million of senior unsecured notes assumed as part of the Merger. The notes were scheduled for maturity in October 2017.

Secured Credit Facility

We maintain a $160.0 million secured credit facility with Prudential Mortgage Capital, which is credit enhanced by the Fannie Mae Facility. The Fannie Mae Facility has maturities from 2017 through 2018. Borrowings under the Fannie Mae Facility

totaled $160.0 million at September 30, 2017, all of which was variable rate at an average interest rate of 1.7%. The available borrowing capacity at September 30, 2017 was $160.0 million.

Secured Property Mortgages

At September 30, 2017, we had $933.3 million of fixed rate conventional property mortgages with an average interest rate of 4.0% and an average maturity in 2019. On February 7, 2017, we paid off a $15.8 million mortgage associated with the Grand Cypress apartment community. The mortgage was scheduled for maturity in August 2017. On May 31, 2017, we paid off a $156.4 million mortgage associated with the following apartment communities: CG at Edgewater, CG at Madison, CG at Seven Oaks, CG at Town Park, CG at Barrett Creek, CG at River Oaks, and CG at Huntersville. The mortgage was scheduled for maturity in June 2019. On September 11, 2017, we paid off a $13.9 million mortgage associated with the Venue at Stonebridge Ranch. The loan was scheduled for maturity in December 2017.

In addition to these payoffs, we paid $9.0 million associated with property mortgage principal amortizations during the nine months ended September 30, 2017.

8. Derivatives and Hedging Activities

Risk Management Objective of Using Derivatives

We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage

economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of our debt funding and the use of derivative financial instruments. Specifically, we enter into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future contractual and forecasted cash amounts, principally related to our borrowings, the value of which are determined by changing interest rates, related cash flows and other factors.

Cash Flow Hedges of Interest Rate Risk

Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish these objectives, we use interest rate swaps and interest rate caps as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium.

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. During the three and nine months ended September 30, 2017 and 2016, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt and forecasted issuances of fixed-rate debt. 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 our 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 our variable-rate or fixed-rate debt. During the next twelve months, we estimate that an additional $80,500 will be reclassified to earnings as an increase to Interest expense, which primarily represents the difference between our fixed interest rate swap payments and the projected variable interest rate swap receipts.

As of September 30, 2017, we had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk:

The fair value of our interest rate derivatives designated as hedging instruments at September 30, 2017 included $2.0 million of asset derivatives reported in Other assets and $2.6 million of liability derivatives reported in the Fair market value of interest rate swaps in the Condensed Consolidated Balance Sheet. The fair value of our interest rate derivatives designated as hedging instruments at December 31, 2016 included $2.4 million of asset derivatives reported in "Other assets" and $7.6 million of liability derivatives reported in "Fair market value of interest rate swaps" in the Condensed Consolidated Balance Sheet.

Bifurcated Embedded Derivatives

Additionally, as a result of the Merger (see Note 2), on December 1, 2016, we issued 867,846 shares of MAA Series I preferred stock as consideration. These shares are redeemable, at our option, on and after October 1, 2026, at the redemption price per share of $50 (see Note 10).

This redemption feature embedded in the MAA Series I preferred stock was evaluated in accordance with ASC 815, Derivatives and Hedging, and we determined that we were required to bifurcate the value associated with this feature from its host instrument, the perpetual preferred shares, and account for it as a freestanding derivative on the balance sheet at fair value as a result of the call option.

Thus, the redemption feature embedded in the MAA Series I preferred stock is reported as a derivative asset in "Other assets" on the accompanying Condensed Consolidated Balance Sheets and is adjusted to its fair value at each reporting date, with a corresponding non-cash adjustment to Other non-property income or expense. 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 fair value of $18.2 million at September 30, 2017. This $7.4 million year-to-date increase includes a

purchase price allocation adjustment of $1.6 million related to the Merger opening balance sheet date, which was recorded in the first quarter of 2017 , as well as $5.8 million of year-to-date mark to market adjustments of non-cash income recorded to reflect the change in fair value of the derivative asset in the nine months ended September 30, 2017.

Credit-Risk-Related Contingent Features

As of September 30, 2017, derivatives that were in a net liability position and subject to credit-risk-related contingent features had a termination value of $2.8 million, which included accrued interest but excluded any adjustment for nonperformance risk. These derivatives had a fair value, gross of asset positions, of $2.6 million at September 30, 2017.

Certain of our derivative contracts contain a provision where we could be declared in default on our derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to our default on the indebtedness. As of September 30, 2017, we had not breached the provisions of these agreements. If we had breached these provisions, we could have been required to settle our obligations under the agreements at the termination value of $2.8 million.

Although our derivative contracts are subject to master netting arrangements, which serve as credit mitigants to both us and our counterparties under certain situations, we do not net our derivative fair values or any existing rights or obligations to cash collateral on the Condensed Consolidated Balance Sheets. We did not have any asset or liability derivative balances that were offsetting that would have resulted in reported net derivative balances differing from the recorded gross amount of derivative assets of $2.0 million and $2.4 million (excluding the preferred stock embedded derivative) as of September 30, 2017 and December 31, 2016, respectively, or gross recorded derivative liabilities of $2.6 million and $7.6 million as of September 30, 2017 and December 31, 2016, respectively.

Other Comprehensive Income

MAA's other comprehensive income consists entirely of gains and losses attributable to the effective portion of our cash flow hedges. The chart below shows the change in the balance for the nine months ended September 30, 2017 and 2016 (dollars in thousands):

9. Fair Value Disclosure of Financial Instruments

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

We apply Financial Accounting Standard Board, or FASB, ASC 820 Fair Value Measurements and Disclosures, or ASC 820. ASC 820 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. ASC 820 applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances.

ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

Fixed rate notes payable at September 30, 2017 and December 31, 2016, totaled $3.23 billion and $3.00 billion, respectively, and had estimated fair values of $3.41 billion and $3.13 billion (excluding prepayment penalties), respectively, as of September 30, 2017 and December 31, 2016. The carrying values of variable rate notes payable (excluding the effect of interest rate swap and cap agreements) at September 30, 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 September 30, 2017 and December 31, 2016. The valuation of our debt is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each debt instrument. This analysis reflects

the contractual terms of the debt, and uses observable market-based inputs, including interest rate curves and credit spreads. 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. Our variable rates reset every 30 to 90 days and we conclude that these rates reasonably estimate current market rates. We have determined that inputs used to value our debt fall within Level 2 of the fair value hierarchy and therefore our fair market valuation of debt is considered Level 2 in the fair value hierarchy.

Financial Instruments Carried at Fair Value

Currently, we use interest rate swaps and interest rate caps (options) to manage our interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. 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.

To comply with the provisions of ASC 820, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. In conjunction with the FASB's fair value measurement guidance, we made an accounting policy election to measure the credit risk of our 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 discounted cash flow analysis in which the perpetual value of the preferred shares is compared to the value with the call option giving 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, redeemable at the Company's option, on October 1, 2026, reflecting the redemption price per share, $50, as the price at which the preferred stock is redeemable. The analysis uses observable market-based inputs, including discount rates based on trading data available on the preferred shares to interpolate an as called value and adjusted based treasury rates to determine the present value of cash flows for the called value and the perpetual value in addition to market data available on the preferred shares to interpolate an as called value and discount rate and again adjusted from there to determine the perpetual discount rate using the applicable treasury rates.

We have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, and as a result, all of our derivatives held as of September 30, 2017 and December 31, 2016 were classified as Level 2 in the fair value hierarchy.

The tables below present our assets and liabilities measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016, aggregated by the level in the fair value hierarchy within which those measurements fall.

10. Shareholders' Equity of MAA

On September 30, 2017, 113,627,014 shares of common stock of MAA and 4,200,032 OP Units in the Operating Partnership (excluding the OP Units held by MAA) were issued and outstanding, representing a total of 117,827,046 common shares and units. At September 30, 2016, 75,542,583 shares of common stock of MAA and 4,143,203 OP Units in the Operating Partnership (excluding OP Units held by MAA) were issued and outstanding, representing a total of 79,685,786 common shares and units. There were 108,438 options to acquire shares of MAA common stock outstanding as of September 30, 2017, as compared to 39,084 outstanding options as of September 30, 2016.

During the nine months ended September 30, 2017, 47,956 shares of MAA 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 nine months ended September 30, 2016, 19,727 shares were acquired for that purpose. During the nine months ended September 30, 2017, we issued 10,340 shares related to the exercise of stock options. These exercises resulted in proceeds of $0.4 million. During the nine months ended September 30, 2016, there were no stock options exercised.

11. Partners' Capital of MAALP

Operating Partnership Units

Interests in MAALP are represented by OP Units. As of September 30, 2017, there were 117,827,046 OP Units outstanding, 113,627,014 or 96.4% of which were owned by MAA, MAALP's general partner. The remaining 4,200,032 OP Units were owned by non-affiliated limited partners, or Class A Limited Partners. As of September 30, 2016, there were 79,685,786 OP Units outstanding, 75,542,583 or 94.8% of which were owned by MAA and 4,143,203 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 the Operating Partnership's agreement of limited partnership, or the Partnership Agreement. Unless otherwise stated in the Partnership Agreement, this power includes, but is not limited to, acquiring, leasing, or disposing of any real property; constructing buildings and making other improvements to properties owned; borrowing money, modifying or extinguishing current borrowings, issuing evidence of indebtedness, and securing such indebtedness by mortgage, deed of trust, pledge or other lien on 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. MAA may delegate these and other powers granted if MAA, 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 September 30, 2017, a total of 4,200,032 Class A Units in the Operating Partnership were held by limited partners unaffiliated with MAA, while a total of 113,627,014 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 September 30, 2017, a total of 4,200,032 Class A Units were outstanding and redeemable for 4,200,032 shares of MAA common stock, with an approximate value of $448.9 million, based on the closing price of MAA’s common stock on the NYSE on September 29, 2017, of $106.88 per share. At September 30, 2016, a total of 4,143,203 Class A Units were outstanding and

redeemable for 4,143,203 shares of MAA common stock, with an approximate value of $389.4 million, based on the closing price of MAA’s common stock on the NYSE on September 30, 2016 of $93.99 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 stock.

12. 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.

We are subject to various 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 currently believes, either individually or in the aggregate, the final outcome of such matters will not have any additional material adverse effect on our financial position, results of operations or cash flows.

Loss Contingencies

The outcomes of the claims, disputes and legal proceedings described or referenced above 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, we do 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 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 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 that we consider in this assessment, including with respect to the matters disclosed in this Note, 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.

As of September 30, 2017 and December 31, 2016, the Company's accrual for loss contingencies was $35.1 million and $42.1 million in the aggregate, respectively.

13. Segment Information

As of September 30, 2017, we owned or had ownership interest in 303 multifamily apartment communities in 17 different states and the District of Columbia from which we derived all significant sources of earnings and operating cash flows. Senior management evaluates performance and determines resource allocations of each of our 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 our apartment communities generally has similar economic characteristics, facilities, services, and tenants. The following are the three reportable operating segments for MAA and the Operating Partnership:


•	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.


•	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. Properties in development or lease-up will be added to the same store portfolio on the first day of the calendar year after they have 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 our same store portfolio.

We utilize 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. We believe NOI is a helpful tool in evaluating the operating performance of our 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 from Post Properties have been placed in our Non-Same Store and Other operating segment, as the properties are recent acquisitions and have not been owned and stabilized for at least 12 months as of the first day of the current calendar year.

Revenues and NOI for each reportable segment for the three- and nine- month periods ended September 30, 2017 and 2016 were as follows (dollars in thousands):

15. Recent Accounting Pronouncements

The following table provides a brief description of recent accounting pronouncements that could have a material effect on our financial statements:



Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
ASU 2014-09, Revenue from Contracts with Customers	This 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.	This ASU is effective for annual reporting periods beginning after December 15, 2017, as a result of a deferral of the effective date arising from the issuance of ASU 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date. 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. We will adopt ASU 2014-09 effective January 1, 2018, using the modified retrospective approach. The majority of our revenue is derived from real estate lease contracts, which falls under ASU 2016-02, Leases. Our analysis on non-lease related revenues, which comprise approximately 10% of consolidated revenues, indicates the adoption of this ASU will not have a material impact on our consolidated financial statements and internal accounting policies.
ASU 2016-02, Leases	This 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.	This 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. We are currently evaluating the impact this standard may have on our consolidated financial statements and related disclosures upon adoption.
ASU 2016-09, Improvements to Employee Share-Based Payment Accounting	This ASU amends existing accounting standards for certain aspects of share-based payments to employees. The new guidance will require all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. It also will allow an employer to repurchase more of an employee’s shares than it can today for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur.	This ASU is effective for annual reporting periods beginning after December 15, 2016. We adopted this guidance effective January 1, 2017.	We adopted this standard effective January 1, 2017, using the modified retrospective transition method, with a cumulative-effect adjustment to retained earnings, and there was no material effect on our consolidated financial position or results of operations taken as a whole.



Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)	This 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.	This 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. We expect to adopt ASU 2016-15 as of January 1, 2018. We have determined that 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. We performed an analysis and determined that only the change in classification of debt prepayment or debt extinguishment costs, which we currently report in operating activities, will have a material impact on the statement of cash flows. Upon adoption in Q1 2018, $1.6 million of cash outflows for debt prepayment or extinguishment costs currently reported in net cash provided by operating activities for the nine months ended September 30, 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)	This ASU requires restricted cash to be presented with cash and cash equivalents when reconciling the beginning and ending amounts in the statements of cash flows.	This 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. We expect to adopt ASU 2016-18 as of January 1, 2018. We currently report the change in restricted cash within the operating and investing activities in our consolidated statement of cash flows. Upon adoption in Q1 2018, cash and cash equivalents reported in our consolidated statements of cash flows for the nine months ended September 30, 2017 will increase by approximately $80.3 million to reflect the restricted cash balances. Additionally, net cash used in investing activities will decrease by $10.6 million for the nine months ended September 30, 2017.
ASU 2017-01, Clarifying the Definition of a Business (Topic 805)	This ASU clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business.	This ASU is effective for interim and annual periods beginning after December 15, 2017. We early adopted this standard effective January 1, 2017.	We adopted this standard as of January 1, 2017 and the adoption did not require any additional disclosures. We believe most of our future acquisitions of operating properties will qualify as asset acquisitions and most future transaction costs associated with these acquisitions will be capitalized. Through the third quarter of 2017, acquisition costs totaling $0.6 million related to our acquisition of Charlotte at Midtown were capitalized and allocated to the assets acquired based on the relative fair market value of those underlying assets.
ASU 2017-12, Derivatives and Hedging (Topic 815)	This ASU clarifies hedge accounting requirements, improves disclosure of hedging arrangements, and better aligns risk management activities and financial reporting for hedging relationships.	This 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. We are currently evaluating the impact this standard may have on our consolidated financial statements and related disclosures upon adoption.

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

The following discussion analyzes the financial condition and results of operations of both MAA and the Operating Partnership, of which MAA is the sole general partner and in which MAA owned a 96.4% limited partner interest as of September 30, 2017. MAA conducts substantially all of its business through the Operating Partnership and the Operating Partnership’s various subsidiaries.

Critical Accounting Policies and Estimates

Please refer to our Annual Report on Form 10-K for the year ended December 31, 2016 that we filed with the SEC on February 24, 2017 for discussions of our critical accounting policies. During the nine months ended September 30, 2017, there were no material changes to these policies.

Overview of the Three Months Ended September 30, 2017

As noted earlier, 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 Condensed Consolidated Financial Statements of this Report from the closing date, December 1, 2016, going forward. All properties acquired from Post Properties have been placed in our Non-Same Store and Other operating segment, as the properties are recent acquisitions and have not been owned and stabilized for at least 12 months.

For the three months ended September 30, 2017, net income available for MAA common shareholders was $113.8 million compared to $84.3 million for the three months ended September 30, 2016. Results for the three months ended September 30, 2017 included $58.8 million of gains related to the sale of real estate assets, $4.1 million of merger and integration costs related to the Merger as well as $38.8 million of additional depreciation and amortization expense. Results for the quarter ended September 30, 2016 included $47.7 million of gains related to the sale of real estate assets and $3.9 million of merger costs. These increases to net expense were partially offset by increases in revenues primarily resulting from the Merger, as we experienced a 390.0% increase in our Non-Same Store and Other segment. We also experienced a 2.5% increase in our Large Market Same Store segment revenues and a 2.4% increase in our Secondary Market Same Store segment revenue. The increases in expense were driven by the above mentioned factors and increased property operating expenses primarily in our Non-Same Store and Other segment from the properties we acquired in the Merger resulting in a 381.9% increase in our Non-Same Store and Other segment. We also experienced a 1.7% increase in our Large Market Same Store segment expenses and a 4.2% increase in our Secondary Market Same Store segment expenses.

The drivers of these increases are discussed below in the "Results of Operations" section. Our same store portfolio represents those communities that have been held and have been stabilized for at least 12 months. Communities excluded from the same store portfolio include recent acquisitions, such as the communities acquired as result of the Merger, communities being developed or in lease-up, communities undergoing extensive renovations, and communities identified for disposition. Additional information regarding the composition of our operating segments is included in Note 13 to the Condensed Consolidated Financial Statements included in this Report.

The following table shows our multifamily real estate assets as of September 30, 2017 and 2016:



	September 30, 2017	September 30, 2016
Properties⁽¹⁾	303	251
Units⁽¹⁾	99,881	79,170
Development units	1,434	550
Average effective rent per unit for the three months ended, excluding lease-up and development	$1,180	$1,058
Physical occupancy, excluding lease-up and development	96.4%	96.6%

⁽¹⁾ Includes property/units owned by a nonconsolidated joint venture.

Average effective rent per unit is equal to the average of gross rent amounts after the effect of leasing concessions for occupied units plus prevalent market rates asked for unoccupied units, divided by the total number of units. Leasing concessions represent discounts to the current market rate. We believe average effective rent per unit is a helpful measurement in evaluating average pricing. It does not represent actual rental revenues collected per unit. See discussion of same store average rent per unit and occupancy comparisons in the "Trends" section below.

In addition to the multi-family assets detailed above, twenty-nine of our multifamily properties also include retail components with approximately 600,000 square feet of gross leasable area. We also owned four commercial properties totaling approximately 232,000 square feet of combined gross leasable space at September 30, 2017.

Results of Operations

Comparison of the three months ended September 30, 2017 to the three months ended September 30, 2016

Property Revenues

The following table shows our property revenues by segment for the three months ended September 30, 2017 and September 30, 2016 (dollars in thousands):



	Three months ended September 30,
	2017		2016		Increase		Percentage Increase
Large Market Same Store	$	169,105	$	165,046	$	4,059	2.5	%
Secondary Market Same Store	87,895		85,822		2,073		2.4	%
Same Store Portfolio	257,000		250,868		6,132		2.4	%
Non-Same Store and Other	127,550		26,030		101,520		390.0	%
Total	$	384,550	$	276,898	$	107,652	38.9	%

The increases in property revenues from our Large Market Same Store and Secondary Market Same Store segments are primarily a result of increased average effective rent per unit of 2.8% for both segments year over year, respectively. The increase in property revenues from our Non-Same Store and Other segment is primarily the result of the Merger, as we classified the properties we acquired as non-same store. See the discussion of our segment classification methodology in Note 13 to the Condensed Consolidated Financial Statements included in this Report.

Property Operating Expenses

Property operating expenses include costs primarily consisting of property personnel, building repairs and maintenance, real estate taxes and insurance, utilities, and landscaping. The following table shows our property operating expenses by segment for the three months ended September 30, 2017 and September 30, 2016 (dollars in thousands):



	Three months ended September 30,
	2017		2016		Increase		Percentage Increase
Large Market Same Store	$	64,531	$	63,451	$	1,080	1.7	%
Secondary Market Same Store	34,059		32,698		1,361		4.2	%
Same Store Portfolio	98,590		96,149		2,441		2.5	%
Non-Same Store and Other	50,589		10,497		40,092		381.9	%
Total	$	149,179	$	106,646	$	42,533	39.9	%

The increase in property operating expenses from our Large Market Same Store segment is primarily a result of increases in real estate taxes of $0.5 million and hurricane related expenses resulting from Hurricanes Harvey and Irma of $1.4 million. These were offset by decreases in insurance expense of $0.5 million, and building repairs and maintenance expense of $0.3 million. The increase in property operating expenses from our Secondary Market Same Store segment is primarily a result of increases in real estate taxes of $0.5 million, hurricane related expenses of $0.6 million and personnel expense of $0.2 million. The increase in property expenses from our Non-Same Store and Other segment is primarily the result of the Merger and $0.3 million of hurricane related expenses.

Depreciation and Amortization

Depreciation and amortization expense for the three months ended September 30, 2017 was approximately $117.9 million, an increase of $41.0 million from the three months ended September 30, 2016. The increase in depreciation and amortization expense is primarily due to additional depreciation of $37.9 million resulting from properties acquired from the Merger, in addition to asset additions made in the normal course of business.

Acquisition Expense

During the three months ended September 30, 2017, no significant acquisition expense was recorded. A decrease of approximately $1.0 million from the three months ended September 30, 2016 was due to the adoption of ASU 2017-01, Clarifying the Definition of a Business (Topic 805), during the first quarter of 2017. Based on the adoption of this guidance, acquisition costs related to properties acquired are now capitalized.

Property Management Expenses

Property management expenses for the three months ended September 30, 2017 were approximately $10.3 million, an increase of $2.4 million from the three months ended September 30, 2016. This increase is primarily due to the growth in our portfolio as a result of the Merger.

General and Administrative Expenses

General and administrative expenses for the three months ended September 30, 2017 were approximately $8.4 million, an increase of $1.7 million from the three months ended September 30, 2016. This increase is primarily driven by our growth as a result of the Merger, as well as, increases in legal expenses quarter over quarter.

Merger and Integration Related Expenses

Merger and integration related expenses for the acquisition of Post Properties for the three months ended September 30, 2017 were primarily comprised of approximately $0.1 million legal costs and $4.0 million of systems and professional costs. Such current year expenses were approximately $0.2 million more than the merger and integration related expenses for the then pending acquisition of Post Properties for the three months ended September 30, 2016.

Interest and Other Non-Property Income

Interest and other non-property income for the three months ended September 30, 2017 was approximately $4.3 million, an increase of approximately $4.2 million from the three months ended September 30, 2016. This increase is primarily driven by $4.1 million of quarter-to-date mark-to-market adjustments of the bifurcated embedded derivative related to the MAA Series I preferred stock issued as a result of the Merger.

Interest Expense

Interest expense for the three months ended September 30, 2017 was approximately $39.9 million, an increase of $7.8 million from the three months ended September 30, 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. Additionally, we entered into a new $300.0 million term loan on the closing date of the Merger. During the three months ended June 30, 2017, we issued a public bond with a face value of $600.0 million, bearing interest at 3.60% per annum. Such increases were offset by a slight decrease in interest expense as during July 2017 we paid off the $150.0 million unsecured loan assumed as part of the Merger; the note was scheduled for maturity in October 2017.

Gain on Debt Extinguishment

We recorded a gain on debt extinguishment of $0.8 million for the three months ended September 30, 2017. We did not record a gain or loss for the three months ended September 30, 2016. The current period gain on debt extinguishment resulted from the payoffs of a US Bank term loan with a face value of $150.0 million and a mortgage associated with the Venue at Stonebridge Ranch with a face value of $14.0 million during three months ended September 30, 2017. There was approximately $0.8 million and $0.1 million on the term loan and mortgage, respectively, of unamortized debt adjustments remaining as of the payoff dates. These fair market values were recognized as a gain on debt extinguishment during the three months ended September 30, 2017.

Net Casualty Gain (Loss) After Insurance and Other Settlement Proceeds

During the three months ended September 30, 2017, we recorded a net casualty gain after insurance proceeds of $0.6 million. This increase of $0.6 million from the three months ended September 30, 2016 was due to the receipt of insurance proceeds for a previous casualty loss of $1.3 million, offset by a casualty loss of $0.7 million from damage caused by Hurricane Irma.

Gain on Sale of Depreciable Real Estate Assets

We recorded a gain on sale of depreciable real estate assets of $58.8 million for the three months ended September 30, 2017, an increase of approximately $11.1 million from the three months ended September 30, 2016. Although disposition activity decreased from the three months ended September 30, 2016, gain on sale of depreciable assets increased primarily due to the nature of the real estate assets sold.

Net Income Attributable to Noncontrolling Interests

Net income attributable to noncontrolling interests for the three months ended September 30, 2017 was approximately $4.2 million, a decrease of $0.4 million from the three months ended September 30, 2016. This decrease is primarily due to the dilutive impact of the Merger to minority interest. As a result, our ownership percentage has increased from 94.8% to 96.4% year over year.

Preferred Dividends Distributed

As a result of the Merger, for the three months ended September 30, 2017 we recorded a dividend distribution to holders of MAA Series I preferred stock of $0.9 million. As there were no shares of MAA Series I preferred stock issued and outstanding during the three months ended September 30, 2016, we did not record a preferred dividend distribution in that quarter.

Net Income Available for MAA Common Shareholders

Primarily as a result of the foregoing, net income available for MAA common shareholders increased by approximately $29.5 million for the three months ended September 30, 2017 from the three months ended September 30, 2016.

Comparison of the nine months ended September 30, 2017 to the nine months ended September 30, 2016

Property Revenues

The following table shows our property revenues by segment for the nine months ended September 30, 2017 and September 30, 2016 (dollars in thousands):



	Nine months ended September 30,
	2017		2016		Increase		Percentage Increase
Large Market Same Store	$	503,076	$	487,725	$	15,351	3.1	%
Secondary Market Same Store	261,272		254,685		6,587		2.6	%
Same Store Portfolio	764,348		742,410		21,938		3.0	%
Non-Same Store and Other	381,901		75,740		306,161		404.2	%
Total	$	1,146,249	$	818,150	$	328,099	40.1	%

The increases in property revenues from our Large Market Same Store and Secondary Market Same Store segments are primarily a result of increased average effective rent per unit of 3.3% and 2.8%, respectively, as compared to the six months ended June 30, 2016. The increase in property revenues from our Non-Same Store and Other portfolio is primarily the result of the Merger, as we classified the properties we acquired as non-same store. See the discussion of our segment classification methodology in Note 13 to the Condensed Consolidated Financial Statements included in this Report.

Property Operating Expenses

Property operating expenses include costs primarily consisting of property personnel, building repairs and maintenance, real estate taxes and insurance, utilities, and landscaping. The following table shows our property operating expenses by segment for the nine months ended September 30, 2017 and September 30, 2016 (dollars in thousands):



	Nine months ended September 30,
	2017		2016		Increase		Percentage Increase
Large Market Same Store	$	189,657	$	185,495	$	4,162	2.2	%
Secondary Market Same Store	98,655		95,422		3,233		3.4	%
Same Store Portfolio	288,312		280,917		7,395		2.6	%
Non-Same Store and Other	148,109		29,565		118,544		401.0	%
Total	$	436,421	$	310,482	$	125,939	40.6	%

The increase in property operating expenses from our Large Market Same Store segment is primarily a result of increases in real estate taxes of $3.4 million, utilities expense of $0.5 million, personnel expense of $0.8 million, other operating expense of $0.4 million, and landscaping expense of $0.2 million. These were offset by a decrease in insurance expense of $1.0 million. The increase in property operating expenses from our Secondary Market Same Store Segment is primarily a result of increases in real estate taxes of $1.3 million, utilities expense of $0.4 million, personnel expense of $1.0 million, other operating expense of $0.7 million, and landscaping expense of $0.1 million. These were offset by a decrease in insurance expense of $0.2 million. The increase in property expenses from our Non-Same Store and Other segment is primarily the result of the Merger.

Depreciation and Amortization

Depreciation and amortization expense for the nine months ended September 30, 2017 was approximately $374.3 million, an increase of $146.5 million from the nine months ended September 30, 2016. The increase in depreciation and

amortization expense is primarily due to depreciation of $111.0 million and amortization expenses of $27.7 million resulting from the Merger, in addition to asset additions made in the normal course of business.

Acquisition Expense

During the nine months ended September 30, 2017, no significant acquisition expense was recorded. A decrease of approximately $2.2 million from the nine months ended September 30, 2016 was due to the adoption of ASU 2017-01, Clarifying the Definition of a Business (Topic 805), during the first quarter of 2017. Based on the adoption of this guidance, acquisition costs related to properties acquired are now capitalized.

Property Management Expenses

Property management expenses for the nine months ended September 30, 2017 were approximately $32.0 million, an increase $6.8 million of from the nine months ended September 30, 2016. This increase is primarily due to the growth in our portfolio as a result of the Merger.

General and Administrative Expenses

General and administrative expenses for the nine months ended September 30, 2017 were approximately $30.7 million, an increase of $10.5 million from the nine months ended September 30, 2016. This increase is primarily driven by increases in other corporate general and administrative expenses and legal expenses as a result of the Merger.

Merger and Integration Related Expenses

Merger and integration related expenses for the acquisition of Post Properties, were primarily comprised of approximately $4.0 million legal costs and $10.5 million of systems and professional costs for the nine months ended September 30, 2017. Merger and integration related expenses for the nine months ended September 30, 2016 were approximately $10.6 million less than the Merger and integration related expenses for the nine months ended September 30, 2017 due to the Merger not being complete until December 1, 2016.

Interest and Other Non-property Income

Interest and other non-property income for the nine months ended September 30, 2017 was approximately $7.6 million, an increase of approximately $7.5 million from the nine months ended September 30, 2016. This increase is primarily driven by $5.8 million of year-to-date mark-to-market adjustments of the bifurcated embedded derivative related to the MAA Series I preferred stock issued as a result of the Merger.

Interest Expense

Interest expense for the nine months ended September 30, 2017 was approximately $115.0 million an increase of $18.6 million from the nine months ended September 30, 2016. The increase was 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. Additionally, we entered into a new $300.0 million term loan on the closing date of the Merger. During the three months ended June 30, 2017, we issued a public bond with a face value of $600.0 million, bearing interest at 3.60% per annum. The remainder of the increase was mainly due to interest related to the newly issued bond. Such increases were offset by a slight decrease in interest expense as a result of our July 2017 payoff of a $150.0 million of unsecured notes assumed as part of the Merger; the notes were scheduled for maturity in October 2017.

Gain on Debt Extinguishment

We recorded a gain on debt extinguishment of $3.2 million for the nine months ended September 30, 2017, an increase of approximately $3.2 million from the nine months ended September 30, 2016. This increase was primarily the result of a $4.8 million gain due to the write-offs of the mark-to-market debt adjustments related to the payoffs of the secured mortgages with Fannie Mae and the US Bank Term Loan, partially offset by a cash prepayment penalty of $1.6 million.

Gain on Sale of Depreciable Real Estate Assets

During the nine months ended September 30, 2017, we recorded a gain on the sale of depreciable real estate assets of $59.0 million, an increase of $10.5 million from the nine months ended September 30, 2016. Although disposition activity

decreased from the nine months ended September 30, 2016, gain on sale of depreciable assets increased primarily due to the nature of the real estate assets sold.

Gain on Sale of Non-depreciable Real Estate Assets

During the nine months ended September 30, 2017, no significant gain on sale of non-depreciable real estate assets was recorded. This decrease of approximately $2.1 million from the nine months ended September 30, 2016 was due to a decrease in disposition activity during the nine months ended September 30, 2017.

Gain from Real Estate Joint Ventures

During the nine months ended September 30, 2017, we recorded a gain from real estate joint ventures of $1.0 million. We did not record a significant gain from real estate joint ventures for the nine months ended September 30, 2016. The increase of $1.0 million is due to income attributable to our ownership interest in the Post Mass Avenue joint venture acquired with the Merger.

Net Income Attributable to Noncontrolling Interests

Net income attributable to noncontrolling interests for the nine months ended September 30, 2017 was approximately $7.6 million, a decrease of $1.9 million from the nine months ended September 30, 2016. This decrease is primarily due to the dilutive impact of the Merger to minority interest. As a result, our ownership percentage has increased from 94.8% to 96.4% year over year.

Preferred Dividends Distributed

As a result of the Merger, for the nine months ended September 30, 2017 we recorded a dividend distribution to holders of MAA Series I preferred stock of $2.8 million. As there were no shares of MAA Series I preferred stock issued and outstanding during the nine months ended September 30, 2016, we did not record a preferred dividend distribution in that period.

Net Income Available for MAA Common Shareholders

Primarily as a result of the foregoing, net income available for MAA common shareholders increased by approximately $29.3 million for the nine months ended September 30, 2017 from the nine months ended September 30, 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 GAAP) excluding extraordinary items, asset impairment, gains or losses on disposition of real estate assets, plus net income available 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 document, 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 flow from operating, investing, and financing activities as a measure of liquidity. Management believes that FFO is helpful to investors in understanding our operating performance primarily because its calculation excludes depreciation and amortization expense on real estate assets. We believe that GAAP historical cost depreciation of real estate assets is generally not correlated with changes in the value of those assets, whose value does not diminish predictably over time, as historical cost depreciation implies. While our calculation of FFO is in accordance with the National Association of Real Estate Investment Trusts', or NAREIT's, definition, it may differ from the methodology for calculating FFO utilized by other REITs and, accordingly, may not be comparable to such other REITs.

The following table is a reconciliation of FFO to net income available for MAA common shareholders for the three and nine months ended September 30, 2017 and September 30, 2016 (dollars in thousands):



	Three months ended September 30,						Nine months ended September 30,
	2017			2016			2017			2016
Net income available for MAA common shareholders	$	113,787		$	84,279		$	202,163		$	172,836
Depreciation and amortization of real estate assets	116,882			76,105			371,194			225,328
Gain on sale of depreciable real estate assets	(58,844		)	(47,749		)	(59,045		)	(48,572		)
Loss on disposition within unconsolidated entities	—			—			—			98
Depreciation and amortization of real estate assets of real estate joint ventures	148			—			449			11
Net income attributable to noncontrolling interests	4,249			4,627			7,600			9,508
Funds from operations attributable to the Company	$	176,222		$	117,262		$	522,361		$	359,209

FFO for the three months ended September 30, 2017 increased approximately $59.0 million from the three months ended September 30, 2016 primarily as a result of the increase in total property revenues of approximately $107.7 million, which was offset by the increases in property operating expenses, excluding depreciation and amortization, of $42.5 million, property management expenses of $2.4 million, and general and administrative expenses of $1.7 million.

FFO for the nine months ended September 30, 2017 increased approximately $163.2 million from the nine months ended September 30, 2016 primarily as a result of the increase in total property revenues of approximately $328.1 million, which was offset by the increases in property operating expenses, excluding depreciation and amortization, of $125.9 million, property management expenses of $6.8 million, general and administrative expenses of $10.5 million, and merger and integration related expenses of $10.6 million. The majority of the remaining variance was attributable to an an increase in interest expense of $18.6 million, offset by an increase in interest and other non-property income of $7.5 million.

Trends

During the three months ended September 30, 2017, demand for apartments continued to be strong, as it was during the three months ended September 30, 2016. Physical occupancy for our same store portfolio (which excludes properties acquired through the Merger) ended September 30, 2017 at a strong 96.5% and average daily physical occupancy for our same store portfolio was 96.2% for the quarter. Our same store average effective rent per unit continued to grow, up 2.8% in the three months ended September 30, 2017 as compared to the three months ended September 30, 2016.

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 39 defined Metropolitan Statistical Areas, or MSAs, we are diversified across markets, urban and suburban submarkets, and a variety of monthly rent pricing points.

The current supply level as a result of elevated permitting activity in 2015 and 2016 is impacting our total portfolio from a demand standpoint, particularly properties located in urban submarkets, the majority of which were acquired in the Merger. Our same store portfolio has been impacted somewhat less, primarily due to being in submarkets that have experienced lower supply relative to other submarkets in a given MSA. Encouragingly, according to U.S. Census Bureau data, as of August 2017 year to date, multifamily permitting across our markets was down 2% as compared to August 2016 year to date. This activity should result in relatively lower supply in our markets in the future as compared to the current environment. In addition, we believe the lack of new apartments in the past few years and the demand from new households will help keep supply and demand essentially in balance in most markets. 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 three months ended September 30, 2017, total move outs attributable to single family home rentals for our combined portfolio was just over 6% of total move outs, in line with the three months ended September 30, 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) will continue to support apartment rental demand for our markets.

Our focus is on maintaining strong physical occupancy while increasing pricing where possible through our revenue management system. As noted above, physical occupancy for our same store portfolio for the period ended September 30, 2017 was strong, and the average for the three months ended September 30, 2017 was sustained above 96%. As we move into the typically slower leasing season of the fall and winter, the current level of physical occupancy puts us in a good position to maintain solid pricing growth in the fourth quarter of 2017.

As a result of the Merger, we continue to combine best practices across the entire portfolio that we believe will ultimately enable us to capture more revenues and reduce expenses. Likewise, we believe our scale as a result of the Merger will help achieve efficiencies and create additional buying power that will benefit our properties acquired as part of the Merger as well as our properties that were owned prior to the Merger.

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. The significant changes in cash due to operating, investing and financing activities for the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 are as follows:

Operating Activities

Net cash flow provided by operating activities increased to $553.1 million for the nine months ended September 30, 2017 compared to $389.2 million for the nine months ended September 30, 2016. This change was a result of various items relating to operating performance, including higher revenues as discussed above.

Investing Activities

Net cash used in investing activities during the nine months ended September 30, 2017 was $232.3 million compared to net cash used in investing activities during the nine months ended September 30, 2016 of $216.1 million. The primary drivers of this change were as follows:



	Primary drivers of cash (outflow) inflow during the nine months ended September 30,
	2017			2016			Increase (Decrease) in Net Cash			Percentage Increase (Decrease) in Net Cash
Purchases of real estate and other assets	$	(63,774	)	$	(262,268	)	$	198,494		75.7	%
Normal capital improvements	(82,030		)	(65,351		)	(16,679		)	(25.5	)%
Construction capital and other improvements	(7,171		)	(5,569		)	(1,602		)	(28.8	)%
Renovations to existing real estate assets	(36,692		)	(29,554		)	(7,138		)	(24.2	)%
Development	(142,530		)	(42,611		)	(99,919		)	(234.5	)%
Proceeds from disposition of real estate assets	90,040			187,425			(97,385		)	(52.0	)%
Return of escrow for future acquisitions	10,591			—			10,591			100.0	%

The decrease in purchases of real estate and other assets resulted from the acquisition of one apartment community during the nine months ended September 30, 2017, compared to the acquisition of four apartment communities during the nine months ended September 30, 2016. The decrease in proceeds from the disposition of real estate assets resulted from the sale of three apartment communities and four land parcels during the nine months ended September 30, 2017, compared to the sale of seven apartment communities, one commercial property, and three land parcels during the nine months ended September 30, 2016. The increase in cash outflows for normal capital improvements, construction capital and other improvements, renovations to existing real estate assets, and development compared to prior year primarily resulted from the property portfolio increase as a result of the Merger and the increase in our development pipeline as a result of the Merger. The increase in cash

inflows from the return of escrow for future acquisitions was a result of funding for three 1031(b) transactions offset by the release of three 1031(b) transactions that never occurred during the nine months ended September 30, 2017; there was no net 1031(b) transaction activity during the nine months ended September 30, 2016.

Financing Activities

Net cash used in financing activities increased to $306.5 million for the nine months ended September 30, 2017 compared to $182.9 million for the nine months ended September 30, 2016. The primary drivers of this change were as follows:



	Primary drivers of cash (outflow) inflow during the nine months ended September 30,
	2017			2016			(Decrease) Increase in Net Cash			Percentage (Decrease) Increase in Net Cash
Net change in credit lines	$	(240,000	)	$	130,000		$	(370,000	)	(284.6	)%
Proceeds from notes payable	597,480			—			597,480			100.0	%
Principal payments on notes payable	(345,053		)	(114,753		)	(230,300		)	(200.7	)%
Dividends paid on common shares	(296,441		)	(185,704		)	(110,737		)	(59.6	)%

The decrease in cash outflows related to the net change in credit lines resulted from the decrease in net borrowings of $240.0 million on the KeyBank Facility during the nine months ended September 30, 2017, compared to the increase in net borrowings of $130.0 million on the KeyBank Facility during the nine months ended September 30, 2016. The increase in proceeds from notes payable during the nine months ended September 30, 2017 relates to the May 2017 issuance of senior unsecured notes discussed in Note 7; there was no debt issued during the nine months ended September 30, 2016. The increase in cash outflows from principal payments on notes payable primarily resulted from paying off approximately $186.1 million of secured property mortgages and $150.0 million of unsecured public bonds during the nine months ended September 30, 2017 compared to paying off approximately $68.1 million of 2006 unsecured public bonds, $33.6 million of secured property mortgages, and $7.1 million of unsecured notes payable during the nine months ended September 30, 2016. The increase in cash outflows from dividends paid on common shares primarily resulted from the increased number of common shares outstanding resulting from the Merger and the increase in the dividend rate to $2.61 per share during the nine months ended September 30, 2017 compared to dividend rate of $2.46 per share during the nine months ended September 30, 2016.

Net cash provided by operating activities (computed in accordance with GAAP) was in excess of our funding of normal capital improvements to existing real estate assets, distributions to common unitholders and dividends paid on common shares for both the nine months ended September 30, 2017 and 2016. While we had sufficient liquidity to permit common share distributions at current rates through additional borrowings, if necessary, any significant deterioration in operations could result in our financial resources being insufficient to pay distributions to common shareholders at the current rate, in which event we would be required to reduce the distribution rate.

We believe that we have adequate resources to fund our current operations, annual refurbishment of our properties, and incremental investment in new properties. To the extent additional capital resources are required or deemed desirable, we may, from time to time, issue equity or debt securities.

Equity

As of September 30, 2017, MAA owned 113,627,014 OP Units, comprising a 96.4% limited partnership interest in the Operating Partnership, while the remaining 4,200,032 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 4,200,032 shares of its common stock, that as of September 30, 2017, were issuable upon redemption of OP Units, so that those shares can be sold freely in the public markets.

As of September 30, 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 interest rate cap agreements totaling a notional amount of $50.0 million as of September 30, 2017.

Unsecured Revolving Credit Facility

On October 15, 2015, the Operating Partnership entered into a $750.0 million unsecured revolving credit facility agreement with a syndicate of banks led by KeyBank, or the KeyBank Facility. This credit facility replaced the 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 to $1.0 billion. As of September 30, 2017, we had $250.0 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.

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 September 30, 2017, comprised of:

A $250.0 million term loan with 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 September 30, 2017, this loan was bearing interest at a rate of LIBOR plus 0.98%.

A $150.0 million term loan with 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 September 30, 2017, this loan was bearing interest at a rate of LIBOR plus 0.98%.

A $150.0 million term loan with KeyBank 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 September 30, 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 September 30, 2017, this loan was bearing interest at a rate of LIBOR plus 0.95%.

Senior Unsecured Notes

We have also issued both public and private unsecured notes. As of September 30, 2017, we had approximately $2.0 billion (face value) of publicly issued notes and $310.0 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 of 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 traded 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 semiannually 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 notes issued in May 2017 were used to pay down outstanding amounts of the Unsecured Revolving Credit Facility. As of September 30, 2017, all of these amounts, with the exception of the series of senior notes assumed in the Merger with a face value of $150.0 million that was paid off in July 2017, remained outstanding.

On July 29, 2011, we issued $135.0 million of senior unsecured notes. The notes were offered 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 September 30, 2017.

On August 31, 2012, we issued $175.0 million of senior unsecured notes. The notes were offered in a private placement with four maturity 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; all of which were outstanding at September 30, 2017.

Secured Credit Facility

Approximately 3.6% of our outstanding obligations at September 30, 2017 were borrowed through a credit facility credit enhanced by Fannie Mae, also referred to as the Fannie Mae Facility. The Fannie Mae Facility has a combined line limit of $160.0 million, of which $160.0 million was collateralized, available to borrow, and borrowed at September 30, 2017. Various Fannie Mae rate tranches of the Fannie Mae Facility mature from 2017 through 2018.

Secured Property Mortgages

We also maintain secured property mortgages with the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation, and various life insurance companies. These mortgages are usually fixed rate and can range from five to 10 years in maturity. As of September 30, 2017, we had $933 million of secured property mortgages.

(3) Swapped interest is subject to the ineffective portion of cash flow hedges as described in Note 8 to the Condensed Consolidated Financial Statements included in this Report.

(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 where we hold an equity interest that may be called in the future by the general partner at any time after giving appropriate notice. At September 30, 2017, we have committed to make additional capital contributions totaling $14.2 million that are subject to being called by the general partner.

Off-Balance Sheet Arrangements

As of September 30, 2017, we had a 35.0% ownership interest in the Apartment LLC joint venture, which consists of one apartment community comprised of 269 apartment units, located in Washington, D.C. We also had a 32.0% ownership interest in Real Estate Technology Ventures, L.P. Our investments in these joint ventures are unconsolidated and are recorded using the equity method for the investments in which we do not have a controlling interest.

At September 30, 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.

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 14 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2016, filed with the SEC on February 24, 2017.

Insurance

We renegotiated our insurance programs effective July 1, 2017. We believe that our current property and casualty insurance program in place provides appropriate insurance coverage for financial protection against insurable risks such that any insurable loss experienced that can be reasonably anticipated would not have a significant impact on our liquidity, financial position or results of operations.

Inflation

Our resident leases at the 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.

Impact of Recently Issued Accounting Standards

Note 15 to the Condensed Consolidated Financial Statements included in this Report provides a brief description of recent accounting pronouncements that could have a material effect on our financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Market risk includes risks that arise from changes in interest rates, foreign currency exchange rates, commodity prices, equity prices and other market changes that affect market sensitive instruments. Our primary market risk exposure is to changes in interest rates on our borrowings. At September 30, 2017, 26.3% of our total market 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 September 30, 2017, approximately 85.3% 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.

There have been no material changes in our market risk as disclosed in the Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on February 24, 2017.

PART II – OTHER INFORMATION

Item 1. 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 United States District Court for the District of Columbia alleging that certain of MAA’s apartments violated accessibility requirements of the Fair Housing Act, or the FHA, and the Americans with Disabilities Act of 1990, or the 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 addition, we are subject to various 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 matters cannot be predicted with certainty, we currently believe the final outcome of such matters will not have a material adverse effect on our financial position, results of operations or cash flows.

For more information regarding our legal proceedings, see Note 12 to the Condensed Consolidated Financial Statements included in this Report.
