Explanatory Note

This report combines the quarterly reports on Form 10-Q for the quarter ended March 31, 2014 of Mid-America Apartment Communities, Inc., a Tennessee corporation and Mid-America Apartments, L.P., a Tennessee limited partnership, of which Mid-America Apartment Communities, Inc. is the sole general partner. MAA and its 94.7% owned subsidiary, MAALP, 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” refers 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 the Mid-America Apartments, L.P. Unless the context otherwise requires, the 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 limited partnership interests of the Operating Partnership are referred to as “OP Units” and the holders of the OP Units are referred to as “unitholders”.

As of March 31, 2014, MAA owned 75,009,303 units (or approximately 94.7%) of the limited partnership interests of the Operating Partnership. 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 quarterly reports on Form 10-Q of MAA and the Operating Partnership, including the notes to the consolidated financial statements, into this single 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.

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 limited 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 limited partner 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 are the principal areas of difference between the consolidated financial statements of MAA and those of the Operating Partnership. MAA's shareholders' equity may include shares of preferred stock, shares of common stock, additional paid-in capital, cumulative earnings, cumulative distributions, noncontrolling interest, 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 interest, accumulated other comprehensive income and redeemable common units. Redeemable common units represent the number of outstanding limited partnership units as of the date of the applicable balance sheet, valued at the greater of the closing market price of MAA's common stock or the aggregate value of the individual partners' capital balances. Each redeemable unit may be redeemed by the holder thereof for either cash equal to the fair market value of one share of common stock of MAA at the time of such redemption or, at the option of MAA, one share of common stock of MAA.

2

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 consolidated financial statements in Item 1 of this report;

• certain accompanying notes to the financial statements, including Note 3 - Earnings per Common Share of MAA and Note 4 - Earnings per OP Unit of MAALP; and Note 10 - Shareholders' Equity of MAA and Note 11 - Partners' Capital of MAALP;

• 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

March 31, 2014 and 2013

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

As of March 31, 2014, MAA owned 75,009,303 units (or approximately 94.7%) of the limited partnership interests of the Operating Partnership. 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 notes to the consolidated financial statements 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.

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 limited 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 partnership units.

The presentation of MAA's shareholders' equity and the Operating Partnership's capital are the principal areas of difference between the consolidated financial statements of MAA and those of the Operating Partnership. MAA's shareholders' equity may include shares of preferred stock, shares of common stock, additional paid-in capital, cumulative earnings, cumulative distributions, noncontrolling interest, 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 interest, accumulated other comprehensive income and redeemable common units. Redeemable common units represent the number of outstanding OP Units as of the date of the applicable balance sheet, valued for conversion at the greater of the closing market price of MAA's common stock or the aggregate value of the individual partners' capital balances. Each redeemable OP Unit may be redeemed by the holder thereof for either cash equal to the fair market value of one share of common stock of MAA at the time of such redemption or, at the option of MAA, one share of common stock of MAA.

Organization and Formation of Mid-America Apartment Communities, Inc.

On October 1, 2013, MAA acquired Colonial Properties Trust, or Colonial, when Colonial was merged with and into MAA, with MAA being the surviving entity of the merger, pursuant to an agreement and plan of merger, which is referred to as the parent merger and Martha Merger Sub, LP, or OP Merger Sub, a wholly-owned indirect subsidiary of MAALP, merged with

12

and into Colonial Realty Limited Partnership, or Colonial LP, with Colonial LP being the surviving entity of the merger and becoming a wholly-owned indirect subsidiary of MAALP, which is referred to as the partnership merger. Under the terms of the merger agreement, each Colonial common share was converted into the right to receive 0.36 of a newly issued share of MAA common stock. In addition, each limited partner interest in Colonial LP designated as a “Class A Unit” and a “Partnership Unit” under the limited partnership agreement of Colonial LP, which we refer to in this filing as Colonial LP units, issued and outstanding immediately prior to the effectiveness of the partnership merger was converted into common units in MAALP at the 0.36 conversion rate. The net assets and results of operations of Colonial are included in our consolidated financial statements from the closing date, October 1, 2013 going forward.

As of March 31, 2014, we owned and operated 269 apartment communities comprising 82,730 apartments located in 14 states principally through the Operating Partnership and we also owned an interest in the following unconsolidated real estate joint ventures:

	Percent Owned	Number of Units/Square Feet
Multifamily:
Mid-America Multifamily Fund II, LLC (Fund II)	33.33%	594	(1)
Belterra	10.00%	288	(2)
McKinney	25.00%	—	(3)
Commercial:
Land Title Building	33.30%	29,971

⁽¹⁾ This joint venture is comprised of two apartment communities.

⁽²⁾ This joint venture is not managed by MAA and is not included in our property totals.

⁽³⁾ This joint venture consists of undeveloped land.

As of March 31, 2014, we had four development communities under construction totaling 999 units, with 305 units completed. Total expected costs for the development projects are $146.0 million, of which $98.7 million has been incurred to date. We expect to complete construction on all four projects by the first quarter of 2015. Four of our multifamily properties include retail components with approximately 100,000 square feet of gross leasable area. We also have three wholly owned commercial properties, which we acquired through our merger with Colonial with approximately 287,000 square feet of gross leasable area, excluding tenant owned anchor stores, and one partially owned commercial property with approximately 30,000 square feet of 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 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 95% to 100% of all consolidated subsidiaries. The consolidated financial statements of MAALP presented herein include the accounts of MAALP and all other subsidiaries in which MAALP has a controlling financial interest. MAALP owns, directly or indirectly, 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 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. 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.

13

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. These entities are not variable interest entities. 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.

2.     Business Combinations

Merger of MAA and Colonial

On October 1, 2013, we completed our merger with Colonial. Pursuant to the merger agreement, Martha Merger Sub, LP, or OP Merger Sub, a wholly-owned indirect subsidiary of our Operating Partnership, merged with and into Colonial LP, with Colonial LP being the surviving entity of the merger and becoming a wholly-owned indirect subsidiary of our Operating Partnership, which is referred to as the partnership merger. The partnership merger was part of the transactions contemplated by the agreement and plan of merger entered into on June 3, 2013 among MAA, our Operating Partnership, OP Merger Sub, Colonial, and Colonial LP pursuant to which MAA and Colonial combined through a merger of Colonial with and into MAA, with MAA surviving the merger, which is referred to as the parent merger. Under the terms of the merger agreement, each Colonial common share was converted into the right to receive 0.36 of a newly issued share of MAA common stock. In addition, each limited partner interest in Colonial LP designated as a “Class A Unit” and a “Partnership Unit” under the limited partnership agreement of Colonial LP, which we refer to in this filing as Colonial LP units, issued and outstanding immediately prior to the effectiveness of the partnership merger was converted into common units in our Operating Partnership at the 0.36 conversion rate.

As part of the merger, we acquired 115 wholly owned apartment communities encompassing 34,370 units principally located in the Southeast and Southwest regions of the United States. In addition to the apartment communities, we also acquired four commercial properties totaling approximately 806,000 square feet. The additions have caused us to nearly double in size as a result of the merger. The net assets and results of operations of Colonial are included in our consolidated financial statements from the closing date, October 1, 2013, going forward.

The total purchase price of approximately $2.2 billion was determined based on the number of Colonial shares of common stock and Colonial OP Units outstanding, as of October 1, 2013. In all cases in which MAA’s 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 October 1, 2013 ($62.56 per share). The total purchase price includes $7.3 million of other consideration, a majority of which relates to assumed stock compensation plans. As a result of the Merger, we issued approximately 31.9 million shares of MAA common stock and approximately 2.6 million OP units.

The acquisition 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 NOI and a 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. The following purchase price allocation was based on our valuation, estimates and assumptions of the acquisition date fair value of the tangible and intangible assets acquired and liabilities assumed. While the current allocation of the purchase price is substantially complete, the valuation of the real estate properties and certain other assets and liabilities is in the process of being finalized. We do not expect future revisions, if any, to have a significant impact on our financial position or results of operations.

14

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

Land	$	469,396
Buildings and improvements	3,075,642
Furniture, fixtures and equipment	96,377
Development and capital improvements in progress	113,368
Undeveloped land	58,400
Properties held for sale	33,300
Lease intangible assets	57,946
Cash and cash equivalents	63,454
Restricted cash	6,825
Deferred costs and other assets, excluding lease intangible assets	87,713
Total assets acquired	4,062,421
Notes payable	(1,759,550)
Fair market value of interest rate swaps	(14,961)
Accounts payable, accrued expenses, and other liabilities	(125,034)
Total liabilities assumed, including debt	(1,899,545		)
Total purchase price	$	2,162,876

We incurred merger and integration related expenses of $5.9 million for the three months ended March 31, 2014. These amounts were expensed as incurred and are included in the Consolidated Statement of Operations in the items titled Merger related expenses and Integration related expenses.

The allocation of fair values of the assets acquired and liabilities assumed has changed from the allocation reported in Item 8. Financial Statements and Supplementary Data - Notes to Consolidated Financial Statements, Note 2 of our Annual Report on Form 10-K for the year ended December 31, 2013, filed with the SEC on February 21, 2014. The changes were based on information concerning the subject assets and liabilities that was not yet available at the time of the 10-K filing. These adjustments had no material impact on the results of operations.

3.    Earnings per Common Share of MAA

Basic earnings per share is computed by dividing net income attributable to 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.  Operating partnership units are included in dilutive earnings per share calculations when they are dilutive to earnings per share. For the three months ended March 31, 2014 and 2013, MAA's basic earnings per share is computed using the two-class method, and our diluted earnings per share is computed using the more dilutive of the treasury stock method or two-class method:

⁽¹⁾ Operating partnership units, other dilutive securities, and the related income with each are not included in the diluted earnings per share calculations as they were not dilutive.

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 units outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends 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 unit computations for the three months ended March 31, 2014 and 2013 is presented below:

7.           Borrowings

On March 31, 2014 and December 31, 2013, we had total indebtedness of approximately $3.46 billion and $3.47 billion, respectively. Our indebtedness as of March 31, 2014 consisted of both conventional and tax exempt debt. Borrowings were made through individual property mortgages as well as company-wide credit facilities. We utilize both secured and unsecured debt.

On August 7, 2013, our Operating Partnership entered into a $500 million unsecured revolving credit facility agreement with KeyBank National Association and thirteen other banks. This agreement amends our Operating Partnership's previous unsecured credit facility with KeyBank. Interest is paid using an investment grade pricing grid using LIBOR plus a spread of 0.90% to 1.70%. As of March 31, 2014, we had no borrowings under this facility.

On October 16, 2013, MAALP issued $350 million in aggregate principal amount of notes, maturing on October 15, 2023 with an interest rate of 4.3% per annum (the "2023 Notes"). The purchase price paid by the initial purchasers was 99.047% of the

19

principal amount. The 2023 Notes are general unsecured senior obligations of MAALP and rank equally in right of payment with all other senior unsecured indebtedness of MAALP. Interest on the 2023 Notes is payable on April 15 and October 15 of each year, beginning on April 15, 2014. The net proceeds from the offering after deducting the original issue discount of approximately $3.3 million and underwriting commissions and expenses of approximately $2.3 million was approximately $344.4 million. The 2023 Notes have been reflected net of discount in the consolidated balance sheet. The Company entered into three forward swaps totaling $150 million, which resulted in a total effective interest rate of 4.15%.

On December 13, 2013, MAALP completed a series of exchange offers (the “Exchange Offers”) pursuant to which it exchanged $154,235,000 aggregate principal amount of 6.25% Senior Notes due 2014, $169,161,000 aggregate principal amount of 5.50% Senior Notes due 2015 and $68,130,000 aggregate principal amount of 6.05% Senior Notes due 2016 (collectively, the “Existing Notes”) issued by Colonial Realty Limited Partnership, a Delaware limited partnership and wholly owned subsidiary of MAALP, for $154,235,000 aggregate principal amount of MAALP’s new 6.25% Senior Notes due 2014 (the “2014 Notes”), $169,112,000 aggregate principal amount of MAALP’s new 5.50% Senior Notes due 2015 (the “2015 Notes”) and $68,130,000 aggregate principal amount of MAALP’s new 6.05% Senior Notes due 2016 (the “2016 Notes” and together with the 2014 Notes and the 2015 Notes, the “Exchange Notes”), plus approximately $975,000 in cash.

The Exchange Notes are senior unsecured obligations of MAALP and will rank equally in right of payment with all of MAALP’s other existing and future senior unsecured indebtedness. Interest on the 2014 Notes will accrue from, and including, December 15, 2013 and will be payable on June 15, 2014, which will also be the maturity date for the 2014 Notes. Interest on the 2015 Notes will accrue from, and including, October 1, 2013 and will be payable semiannually on April 1 and October 1 of each year, beginning on April 1, 2014. Interest on the 2016 Notes accrued from, and including, September 1, 2013 and was paid on March 1, 2014. Interest payments will be payable semiannually on March 1 and September 1 of each year, beginning on March 1, 2014. In certain circumstances described below MAALP may be required to pay additional interest on the Exchange Notes.

The Indenture under which the 2023 notes were issued and the Indentures contain certain covenants that, among other things, limit the ability of MAALP and its subsidiaries to incur secured and unsecured indebtedness if not in pro forma compliance with the following negative covenants: (1) total leverage not to exceed 60% of adjusted total assets, (2) secured leverage not to exceed 40% of adjusted total assets and (3) a fixed charge coverage ratio of at least 1.50 to 1. In addition, MAALP is required to maintain at all times unencumbered consolidated total assets of not less than 150% of the aggregate principal amount of its outstanding unsecured debt. At March 31, 2014, MAALP was in compliance with each of these financial covenants.

All of the Existing Notes tendered into the Exchange Offers were cancelled in connection with the settlement of the Exchange Offers. In connection with the issuance and sale of the Exchange Notes, MAALP also entered into three separate registration rights agreements, each dated as of December 13, 2013, and each with J.P. Morgan Securities LLC, the dealer manager in the Exchange Offers (the “Registration Rights Agreements”). Under the Registration Rights Agreements, MAALP agreed to use commercially reasonable efforts to complete exchange offers registered under the Securities Act pursuant to which MAALP will offer to issue new exchange notes containing terms substantially similar in all material respects to the Exchange Notes (except that the exchange notes will not contain terms with respect to transfer restrictions or any increase in annual interest rate) in exchange for the Exchange Notes. MAALP also agreed, if it determines that a registered exchange offer is not available or specified other circumstances occur, to use commercially reasonable efforts to file and have become effective a shelf registration statement relating to resales of the Exchange Notes. MAALP will be obligated to pay additional interest of up to 0.50% per annum on the Exchange Notes if it does not complete the exchange offers within 270 days after the issue date of the Exchange Notes and in other specified circumstances.

As of March 31, 2014, approximately 18% of our outstanding debt was borrowed through secured credit facility relationships with Prudential Mortgage Capital, which are credit enhanced by the Federal National Mortgage Association, or FNMA, and Financial Federal, which are credit enhanced by Federal Home Loan Mortgage Corporation, or Freddie Mac.

We utilize interest rate swaps and interest rate caps to help manage our current and future interest rate risk and entered into 14 interest rate swaps and 7 interest rate caps as of March 31, 2014, representing notional amounts totaling $717.0 million and $180.0 million, respectively. We also held 15 non-designated interest rate caps with notional amounts totaling $134.3 million as of March 31, 2014.

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 this objective, 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 months ended March 31, 2014 and 2013, 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. During the three months ended March 31, 2014 and 2013, we recorded ineffectiveness of $4,000 (increase to interest expense) and $4,000 (decrease to

21

interest expense), respectively, mainly attributable to a mismatch in the underlying indices of the derivatives and the hedged interest payments made on our variable-rate debt.

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 12 months, we estimate that an additional $9.7 million 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 payments.

As of March 31, 2014, we had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk:

Interest Rate Derivative	Number of Instruments	Notional
Interest Rate Caps	7	$	180,000,000
Interest Rate Swaps (1)	14	$	717,000,000

⁽¹⁾ Excludes four forward rate swaps totaling $200 million where the debt has not yet been issued. These swaps are not included in our debt discussion in MD&A or Item 1. Financial Statements – Notes to Consolidated Financial Statements, Note 7.

Non-Designated Hedges

Derivatives not designated as hedges are not speculative and are used to manage the Company's exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements of FASB ASC 815, Derivatives and Hedging. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings and resulted in a loss of $69,000 for the three months ended March 31, 2014 and a loss of $13,000 for the three months ended March 31, 2013.

As of March 31, 2014, we had the following outstanding interest rate derivatives that were not designated as hedges:

Interest Rate Derivative	Number of Instruments	Notional
Interest rate caps	15	$	134,326,000

Credit-Risk-Related Contingent Features

As of March 31, 2014, derivatives that were in a net liability position and subject to credit-risk-related contingent features had a termination value of $19.6 million, which includes accrued interest but excludes any adjustment for nonperformance risk. These derivatives had a fair value, gross of asset positions, of $17.9 million at March 31, 2014.

Certain of our derivative contracts contain a provision where if we default on any of our indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then we could also be declared in default on our derivative obligations. As of March 31, 2014, 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 their termination value of $3.4 million.

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 March 31, 2014, we had not breached the provisions of these agreements. If we had breached theses provisions, we could have been required to settle our obligations under the agreements at the termination value of $14.9 million.

Certain of our derivative contracts are credit enhanced by either FNMA or Freddie Mac.  These derivative contracts require that our credit enhancing party maintain credit ratings above a certain level.  If our credit support providers were downgraded below Baa1 by Moody’s or BBB+ by Standard & Poor’s, or S&P, we may be required to either post 100 percent collateral or settle the obligations at their termination value of $4.7 million as of March 31, 2014.  Both FNMA and Freddie Mac are currently rated Aaa by Moody’s and AA+ by S&P, and therefore, the provisions of this agreement have not been breached, and no collateral has been posted related to these agreements as of March 31, 2014.

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.

On January 1, 2008, we adopted Financial Accounting Standards 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 March 31, 2014 and December 31, 2013, totaled $2.30 billion and $2.29 billion, respectively, and had estimated fair values of $2.33 billion and $2.30 billion (excluding prepayment penalties), respectively, as of March 31, 2014 and December 31, 2013. The carrying value of variable rate notes payable (excluding the effect of interest rate swap and

27

cap agreements) at March 31, 2014 and December 31, 2013, totaled $1.16 billion and $1.18 billion, respectively, and had estimated fair values of $1.07 billion and $1.12 billion (excluding prepayment penalties), respectively, as of March 31, 2014 and December 31, 2013. 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 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 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.

Currently, we use interest rate swaps and interest rate caps (options)to manage our interest raterisk. 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.

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 March 31, 2014 and December 31, 2013 were classified as Level 2 of the fair value hierarchy.

The table below presents our assets and liabilities measured at fair value on a recurring basis as of March 31, 2014 and December 31, 2013, aggregated by the level in the fair value hierarchy within which those measurements fall.

10.           Shareholders' Equity of MAA

On March 31, 2014, 75,009,303 shares of common stock of MAA and 4,208,526 partnership units in the Operating Partnership were issued and outstanding, representing a total of 79,217,829 shares and units. At March 31, 2013, 42,683,322 shares of common stock of MAA and 1,707,660 partnership units in the Operating Partnership were outstanding, representing a total of 44,390,982 shares and units. There were 296,583 outstanding options as of March 31, 2014 compared to zero outstanding options as of March 31, 2013. The primary reason for the increase in shares and units is due to the merger with Colonial. In connection with the merger, on October 1, 2013, we issued 31,916,765 shares and 2,574,631 partnership units.

On August 26, 2010, we and our Operating Partnership entered into sales agreements with Cantor Fitzgerald & Co., Raymond James & Associates, Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated to sell up to a combined total of 6,000,000 shares of our common stock, from time to time in at-the-market offerings or negotiated transactions through a controlled equity offering program, or ATM. We terminated this ATM program, and on February 25, 2013, we and our Operating Partnership entered into sales agreements with J.P. Morgan Securities LLC, BMO Capital Markets Corp., KeyBanc Capital Markets Inc. and UBS Securities LLC to sell up to 4,500,000 shares of our common stock with materially the same terms as our previous sales agreements.

During the three-month period ended March 31, 2014, we issued no shares through our ATM programs. During the three-month period ended March 31, 2013, we issued 325,166 shares through our ATM programs for net proceeds of $22.0 million. The gross proceeds for these issuances were $22.3 million. We have 4,134,989 shares remaining under our ATM program as of March 31, 2014.

During the three-month period ended March 31, 2014, we issued 340 shares of common stock through the optional cash purchase feature of our Dividend and Distribution Reinvestment and Share Purchase Program, or DRSPP. The issuances resulted in gross proceeds of approximately $23,000. During the three-month period ended March 31, 2013, we issued 141 shares of common stock through the optional cash purchase feature of our DRSPP resulting in gross proceeds of approximately $10,000.

During the three months ended March 31, 2014, 6,554 shares of our 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 three months ended March 31, 2013, 4,582 shares were acquired for these purposes.

11.    Partners' Capital of Mid-America Apartments, L.P.

Interests in MAALP are represented by OP Units. As of March 31, 2014, there were 79,217,829 OP Units outstanding, 75,009,303 or 94.7% of which were owned by MAA, MAALP's general partner. The remaining 4,208,526 OP Units were owned by non-affiliated limited partners ("Class A Limited Partners"). As of March 31, 2013, there were 44,390,982 OP Units outstanding, 42,683,322 or 96.2% of which were owned by MAA and 1,707,660 of which were owned by the Class A Limited Partners. The increase in OP Units was due primarily to the merger with Colonial Properties Trust. In order to complete the merger, on October 1, 2013, we issued 34,491,396 OP Units.

29

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

Under the Partnership Agreement, the Operating Partnership may issue Class A OP Units and Class B OP Units. Class A OP 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 OP Units may only be held by MAA, in its capacity as general partner of the Operating Partnership, and as of March 31, 2014, a total of 4,208,526 Class A OP Units in the Operating Partnership were held by limited partners unaffiliated with MAA, while a total of 75,009,303 Class B OP 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 OP Units is also limited by the Partnership Agreement.

Net income 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 OP Units or Class B OP Units changes the relative ownership percentage of the partners. The issuance of Class B OP Units generally occurs when MAA issues common stock and the proceeds from that issuance are contributed to 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 OP Units with similar terms held by MAA for a redemption price equal to the purchase price of those shares of common stock. At each reporting period, the allocation between general partner capital and limited partner capital is adjusted to account for the change in the respective percentage ownership of the underlying capital of the Operating Partnership. Holders of the Class A OP Units may require MAA to redeem their Class A OP Units, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per Class A OP Unit equal, in general, to the average closing price of MAA's common stock on the New York Stock Exchange over a specified period prior to the redemption date) or by delivering one share of MAA common stock (subject to adjustment under specified circumstances) for each Class A OP Unit so redeemed.

At March 31, 2014, a total of 4,208,526 Class A OP Units were outstanding and redeemable for 4,208,526 shares of MAA common stock or approximately $287,316,070, based on the closing price of MAA’s common stock on March 31, 2014 of $68.27 per share, at MAA’s option. At March 31, 2013, a total of 1,707,660 Class A OP Units were outstanding and redeemable for 1,707,660 shares of MAA common stock or approximately $117,931,000, based on the closing price of MAA’s common stock on March 31, 2013 of $69.06 per share, at MAA’s option.

The Operating Partnership pays the same per unit distribution in respect to the OP Units as the per share dividend MAA pays in respect to its common and preferred stock.

12.     Legal Proceedings

The Company (by virtue of its merger with Colonial) and Colonial LP along with multiple other parties, are named defendants in lawsuits arising out of alleged construction deficiencies with respect to condominium units at Regatta at James Island in Charleston, South Carolina. Regatta at James Island property was developed by certain of the Company's subsidiaries and constructed by Colonial Construction Services, LLC. The condominiums were constructed in 2006 and all 212 units were sold. The lawsuits, one filed on behalf of the condominium homeowners association and one filed by three of the unit owners (purportedly on behalf of all unit owners), were filed in South Carolina state court (Charleston County) in August 2012, against various parties involved in the development and construction of the Regatta at James Island property, including the contractors, subcontractors, architect, developer, and product manufacturers. The plaintiffs are seeking damages resulting primarily from alleged construction deficiencies, but the amount plaintiffs seek to recover has not been disclosed. The lawsuits are currently in discovery. The Company is continuing to investigate the matter and evaluate its options and intends to vigorously defend itself against these claims. No assurance can be given that the matter will be resolved favorably to the Company. The Companyhas included in its loss contingency an estimate of probable loss in connection with this matter, but currently cannot reasonably estimate any further possible loss, or any range of reasonably possible loss, in connection with this matter.

30

The Company (by virtue of its merger with Colonial) and Colonial LP along with multiple other parties, are named defendants in a lawsuit arising out of alleged construction deficiencies with respect to condominium units at Plantation Point in Bluffton, South Carolina. Plantation Point was previously owned and operated by Colonial LP as a multi-family rental project by the name of the Ashley Plantation apartments. Colonial LP sold the property in 2005 to a third party, which then converted the property to condominiums and sold all 414 units. The lawsuit, filed on behalf of the condominium homeowners association and a class of unit owners, was filed in South Carolina state court (Beaufort County) in September 2011, against various parties involved in the development, construction and conversion of the Plantation Point property, including the contractors, subcontractors, architect, developer, and product manufacturers. The plaintiffs are seeking $24.7 million in damages resulting from, among other things, alleged construction deficiencies and misleading sales practices attributed to the third-party seller. The lawsuit is currently in discovery. The Company is continuing to investigate the matter and evaluate its options and intends to vigorously defend itself against these claims. No assurance can be given that the matter will be resolved favorably to the Company. The Company has included in its loss contingency an estimate of probable loss in connection with this matter, but currently cannot reasonably estimate any further possible loss, or any range of reasonably possible loss, in connection with this matter.

On June 19, 2013, a putative class action was filed in the Circuit Court for Jefferson County, Alabama captioned Williams v. Colonial Properties Trust, et al., No. 01-CV-2013-902416.00 (the “Williams Litigation”), seeking, among other things, to enjoin the previously announced combination of MAA and Colonial in accordance with the terms of the Agreement and Plan of Merger, dated June 3, 2013, by and among MAA, the Operating Partnership, Martha Merger Sub, LP, Colonial and Colonial LP. On March 6, 2014 the Court approved the final settlement of the Williams litigation and the Company made the Court-approved immaterial payment to the Plaintiff's attorneys.

In addition, the Company is subject to various other legal proceedings and claims that arise in the ordinary course of its business operations. Matters which arise out of allegations of bodily injury, property damage, and employment practices are generally covered by insurance. While the resolution of these other matters cannot be predicted with certainty, management currently believes the final outcome of such matters will not have a material adverse effect on the financial position, results of operations or cash flows of the Company.

Loss Contingencies

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

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

13.           Discontinued Operations

In April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. We adopted ASU 2014-08 during the period ending March 31, 2014. Due to the early adoption of ASU 2014-08, we did not classify Brookwood Mall, which was sold on March 30, 2014, as a discontinued operation.

Willow Creek, one of the properties that we sold during the three months ended March 31, 2014, as well as the eight properties sold by us during 2013, have been classified as discontinued operations in the Consolidated Statements of Operations. One additional property, Colonial Promenade Nord du Lac, that was classified as held for sale during the first quarter of 2014 was classified as a discontinued operation. Willow Creek and Colonial Promenade Nord du Lac are included in discontinued operations because they were shown in discontinued operations as of December 31, 2013, our latest fiscal year, and thus are not subject to ASU 2014-08.

The following table lists the communities classified as discontinued operations for the three months ended March 31, 2014:

Community	Units/Sq. Ft.	Date Sold	Location	Operating Segment
Willow Creek	285	January 15, 2014	Columbus, Georgia	Secondary market same store

14.           Segment Information

As of March 31, 2014, we owned or had an ownership interest in 271 multifamily apartment communities in 14 different states from which we derived all significant sources of earnings and operating cash flows. Senior management evaluates performance and determines resource allocations by reviewing apartment communities individually and in the following reportable operating segments:

• Large market same store communities are generally communities:

◦ in markets with a population of at least 1 million and at least 1% of the total public multifamily REIT units; and

◦ that we have owned and have been stabilized for at least a full 12 months and have not been classified as held for sale.

• 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 in markets with a population of less than 1 million; and

◦ that we have owned and have been stabilized for at least a full 12 months and have not been classified as held for sale.

• Non same store communities and other includes recent acquisitions, communities in development or lease-up and communities that have been identified for disposition. Also included in non same store communities are non multifamily activities, which represent less than 1% of our portfolio.

On the first day of each calendar year, we determine the composition of our same store operating segments for that year as well as adjusting 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 net operating income, or NOI, a non-GAAP financial measure, 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.

15.           Real Estate Acquisitions and Dispositions

On January 15, 2014, we closed on the purchase of the 312-unit Grand Cypress apartment community located in Cypress (Houston), Texas. This property was previously a part of our Fund II Joint Venture.

On January 31, 2014, we closed on the purchase of the 250-unit Venue at Stonebridge Ranch apartment community located in McKinney (Dallas), Texas. This property was previously a part of our Fund II Joint Venture.

During the three months ended March 31, 2014, we closed on the sale of two parcels of land located in Birmingham, Alabama, two parcels of land located in Orlando, Florida, and one parcel of land located in Covington, Louisiana. These parcels were acquired as part of the merger with Colonial.

16.           Recent Accounting Pronouncements

Impact of Recently Issued Accounting Standards

In April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 raises the threshold for disposals to qualify as discontinued operations. It also requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. The ASU is effective for fiscal years beginning after December 15, 2014, and interim periods within those years; however, early adoption is permitted beginning in the first quarter of 2014. We adopted ASU 2014-08 during the period ending March 31, 2014. The adoption of ASU 2014-08 required us to not classify certain disposals occurring during the first quarter of 2014 as discontinued operations.

In January 2013, the FASB issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. ASU 2013-01 clarifies that the scope of ASU 2011-11, Disclosures about Offsetting Assets and Liabilities, would apply to derivatives accounted for in accordance with FASB ASC 815, Derivatives and Hedging, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with ASC 210-20-45 or ASC 815-10-45 or subject to an enforceable master netting arrangement or similar agreement. This ASU is effective for fiscal years beginning on or after January 1, 2013 and interim periods within those annual periods. We adopted ASU 2013-01 during the period ended March 31, 2013. The adoption of ASU 2013-01 has not had a material impact on our consolidated financial condition or results of operations taken as a whole.

17. Subsequent Events

Financing

On April 10, 2014, we entered into a forward interest rate swap agreement to effectively lock an additional $50 million in planned future debt transactions. This forward swap had an interest rate of 2.8%.

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 the MAA is the sole general partner and in which MAA owned a 94.7% limited partner interest as of March 31, 2014. MAA conducts all of its business through the Operating Partnership and the Operating Partnership’s various subsidiaries.

The following discussion should be read in conjunction with the condensed consolidated financial statements and notes appearing elsewhere in this Quarterly Report.  Historical results and trends that might appear in the condensed consolidated financial statements should not be interpreted as being indicative of future operations.

Risk Associated with Forward Looking Statements

We consider this and other sections of this Quarterly Report on Form 10-Q to contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, with respect to our expectations for future periods. The factors described in Part I, Item 1A, “Risk Factors,” in our Annual Report on Form 10-K for the year ended December 31, 2013, as updated in Part II, Item 1A in this Quarterly Report on Form 10-Q, among others, could cause actual results to differ materially from those contained in forward-looking statements made in this Quarterly Report on Form 10-Q, in the documents incorporated by reference into this Quarterly Report on Form 10-Q or presented elsewhere by our management from time to time. Forward-looking statements do not discuss historical fact, but instead include statements related to expectations, projections, intentions or other items related to the future. Such forward-looking statements include, without limitation, statements concerning property acquisitions and dispositions, joint venture activity, development and renovation activity as well as other capital expenditures, capital raising activities, rent and expense growth, occupancy, financing activities and interest rate and other economic expectations and statements about the benefits of our merger with Colonial Properties Trust, or Colonial. Words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” and variations of such words and similar expressions are intended to identify such forward-looking statements. Such statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements to be materially different from the results of operations, financial conditions or plans expressed or implied by such forward-looking statements. Such factors include, among other things, unanticipated adverse business developments affecting us, or our properties, adverse changes in the real estate markets and general and local economies and business conditions. Although we believe that the assumptions underlying the forward-looking statements contained herein are reasonable, any of the assumptions could be inaccurate, and therefore such forward-looking statements included in this report may not prove to be accurate. In light of the significant uncertainties inherent in the forward-looking statements included herein, the inclusion of such information should not be regarded as a representation by us or any other person that the results or conditions described in such statements or our objectives and plans will be achieved.

The following factors, among others, could cause our future results to differ materially from those expressed in the forward-looking statements:

• inability to generate sufficient cash flows due to market conditions, changes in supply and/or demand, competition, uninsured losses, changes in tax and housing laws, or other factors;

• exposure, as a multifamily focused REIT, to risks inherent in investments in a single industry;

• difficulty in integrating Colonial’s operations, systems and personnel with ours and certain uncertainties associated with our ability to sell our commercial asset portfolio;

• adverse changes in real estate markets, including, but not limited to, the extent of future demand for multifamily units in our primary markets, barriers of entry into new markets which we may seek to enter in the future, limitations on our ability to increase rental rates, competition, our ability to identify and consummate attractive acquisitions or development projects on favorable terms, our ability to consummate any planned dispositions in a timely manner on acceptable terms, and our ability to reinvest sale proceeds in a manner that generates favorable returns;

• failure of new acquisitions to achieve anticipated results or be efficiently integrated;

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

• unexpected capital needs;

• changes in operating costs, including real estate taxes, utilities and insurance costs;

• losses from catastrophes in excess of our insurance coverage;

• ability to obtain financing at favorable rates, if at all, and refinance existing debt as it matures;

• level and volatility of interest or capitalization rates or capital market conditions;

• loss of hedge accounting treatment for interest rate swaps or interest rate caps;

• the continuation of the good credit of our interest rate swap and cap providers;

Critical Accounting Policies and Estimates

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

We believe that the estimates and assumptions listed below are most important to the portrayal of our financial condition and results of operations because they require the greatest subjective determinations and form the basis of accounting policies deemed to be most critical. These critical accounting policies include revenue recognition, capitalization of expenditures and depreciation and amortization of assets, acquisition of real estate assets, impairment of long-lived assets, including goodwill, fair value of derivative financial instruments and loss contingencies.

Revenue Recognition and Real Estate Sales

We primarily lease multifamily residential apartments under operating leases generally with terms of one year or less. Rental revenues are recognized using a method that represents a straight-line basis over the term of the lease and other revenues are recorded when earned.

We record gains and losses on real estate sales in accordance with accounting standards governing the sale of real estate. For sale transactions meeting the requirements for the full accrual method, we remove the assets and liabilities from our Consolidated Balance Sheets and record the gain or loss in the period the transaction closes. For properties contributed to joint ventures, MAA records gains on the partial sale in proportion to the outside partners’ interest in the venture.

Capitalization of expenditures and depreciation and amortization of assets

We carry real estate assets at depreciated cost. Depreciation and amortization is computed on a straight-line basis over the estimated useful lives of the related assets, which range from 8 to 40 years for land improvements and buildings, 5 years for furniture, fixtures, and equipment, 3 to 5 years for computers and software, and 6 months for acquired multifamily leases, all of which are subjective determinations. Repairs and maintenance costs are expensed as incurred while significant improvements, renovations and replacements are capitalized. The cost to complete any deferred repairs and maintenance at properties acquired by us in order to elevate the condition of the property to our standards are capitalized as incurred.

Acquisition of real estate assets

We account for our acquisitions of investments in real estate in accordance with ASC 805-10, Business Combinations, which requires the fair value of the real estate acquired to be allocated to the acquired tangible assets, consisting of land, building and furniture, fixtures and equipment, and identified intangible assets, generally consisting of the value of in-place leases.

We allocate the purchase price to the fair value of the tangible assets of an acquired property, which includes the land, building, and furniture, fixtures, and equipment, determined by valuing the property as if it were vacant, based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a property using methods similar to those used by independent appraisers. These methods include using stabilized Net Operating

38

Income, or NOI, and market specific capitalization and discount rates. The purchase price is also allocated to any debt and other liabilities that are assumed as part of the transaction.

In allocating the fair value of identified intangible assets of an acquired property, the in-place leases are valued based on current rent rates and time and cost to lease a unit. Management concluded that the residential leases acquired on each of its property acquisitions are approximately at market rates since the lease terms generally do not extend beyond one year.

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. The third party uses stabilized NOI and market specific capitalization and discount rates. Management reviews the inputs used by the third party specialist as well as the allocation of the purchase price provided by the third party to ensure reasonableness and that the procedures are performed in accordance with management's policy. The initial allocation of the purchase price is based on management’s preliminary assessment, which may differ when final information becomes available. Subsequent adjustments made to the initial purchase price allocation, if any, are made within the allocation period, which typically does not exceed one year.

Impairment of long-lived assets, including goodwill

We account for long-lived assets in accordance with the provisions of accounting standards for the impairment or disposal of long-lived assets and evaluate our goodwill for impairment under accounting standards for goodwill and other intangible assets. We evaluate goodwill for impairment on at least an annual basis, or more frequently if a goodwill impairment indicator is identified. We periodically evaluate long-lived assets, including investments in real estate and goodwill, for indicators that would suggest that the carrying amount of the assets may not be recoverable. The judgments regarding the existence of such indicators are based on factors such as operating performance, market conditions and legal factors.

Long-lived assets, such as real estate assets, equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented on the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of properties classified as held for sale are presented separately in the appropriate asset and liability sections of the balance sheet.

Goodwill is tested annually for impairment, and is tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss for goodwill is recognized to the extent that the carrying amount exceeds the implied fair value of goodwill. This determination is made at the reporting unit level and consists of two steps. First, we determine the fair value of a reporting unit and compare it to its carrying amount. In the apartment industry, the primary method used for determining fair value is to divide annual operating cash flows by an appropriate capitalization rate. We determine the appropriate capitalization rate by reviewing the prevailing rates in a property’s market or submarket. Second, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation in accordance with accounting standards for business combinations. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill.

Fair value of derivative financial instruments

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

In order for a derivative contract to be designated as a hedging instrument, changes in the hedging instrument must be highly effective at offsetting changes in the hedged item. The historical correlation of the hedging instruments and the underlying hedged items are assessed before entering into the hedging relationship and on a quarterly basis thereafter, and have been found to be highly effective.

39

We measure ineffectiveness using the change in the variable cash flows method or the hypothetical derivative method for interest rate swaps and the hypothetical derivative method for interest rate caps for each reporting period through the term of the hedging instruments. Any amounts determined to be ineffective are recorded in earnings if in an overhedged position. The change in fair value of the interest rate swaps and the intrinsic value or fair value of interest rate caps designated as cash flow hedges are recorded to accumulated other comprehensive income in the statement of shareholders’ equity.

The valuation of our derivative financial instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts.  The variable cash 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 caps 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 interest rate caps.  The variable interest rates used in the calculation of projected receipts on the interest rate cap are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities.Additionally, 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. Changes in the fair values of our derivatives are primarily the result of fluctuations in interest rates. See Notes 8 and 9 of the accompanying Condensed Consolidated Financial Statements for further discussion.

Loss Contingencies

The outcomes of claims, disputes and legal proceedings including those described in Item 1 — Legal Proceedings of this Form 10-Q 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 that is disclosed.

The assessment of whether a loss is probable or a reasonable possibility, and whether the loss or range of loss is reasonably estimable, often involve 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 Item 1 — Legal Proceedings of this Form 10-Q, 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.

Overview of the Three Months Ended March 31, 2014

As noted earlier, on October 1, 2013, we consummated the Merger and acquired all of Colonial's net assets. Our March 31, 2014 and December 31, 2013 balance sheets include the combined assets and liabilities of MAA and Colonial. All properties acquired from Colonial have been placed in our Non-Same Store operating segment, as the properties are recent acquisitions and have not been owned and stabilized for at least 12 months.

We experienced an increase in income from continuing operations for the three months ended March 31, 2014 over the three months ended March 31, 2013 as increases in revenues outpaced increases in expenses. The increases in revenues came from a 4.0% increase in our large market same store segment, a 1.9% increase in our secondary market same store segment and a 1,216.9% increase in our non-same store and other segment, which was primarily a result of the merger. The increase in expense came from a 5.5% increase in our large market same store segment, a 2.7% increase in our secondary market same store segment and a 1,176.4% increase in our non-same store and other segment, which was primarily the result of the merger. 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 would include recent acquisitions, communities being developed or in

40

lease-up, communities undergoing extensive renovations, and communities identified as discontinued operations. The drivers of these increases are discussed below in the results of operations section.

The following table shows our multifamily real estate assets as of March 31, 2014 and 2013:

	Three months ended March 31,
	2014	2013
Properties	271	161
Units	83,324	48,225
Development Units	999	774
Average Effective Monthly Rent/Unit, excluding lease-up and development	$900.86	$861.76
Occupancy, excluding lease-up and development	95.5%	96.1%

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, we also owned or owned an interest in four commercial properties totaling 317,000 square feet of leasable space.

Average effective monthly 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 monthly rent is a helpful measurement in evaluating average pricing. It does not represent actual rental revenue collected per unit.

The following is a discussion of our consolidated financial condition and results of operations for the three-month periods ended March 31, 2014and2013.This discussion should be read in conjunction with all of the consolidated financial statements included in this Quarterly Report on Form 10-Q.

Results of Operations

Comparison of the three months ended March 31, 2014, to the three months ended March 31, 2013

Property Revenues

The following table shows our property revenues by segment for the three months ended March 31, 2014 and March 31, 2013 (dollars in thousands):

	Three months ended March 31,
	2014		2013		Increase		Percentage Increase
Large Market Same Store	$	60,453	$	58,125	$	2,328	4.0	%
Secondary Market Same Store	61,531		60,399		1,132		1.9	%
Non-Same Store and Other	121,406		9,219		112,187		1,216.9	%
Total	$	243,390	$	127,743	$	115,647	90.5	%

The increases in property revenues from our large market same store and secondary market same store groups are primarily a result of increased average rent per unit of 4.5%. The increase in property revenues from our non-same store and other group is primarily due to the addition of the Colonial portfolio as a result of the Merger.

Property Operating Expenses

Property operating expenses include costs for property personnel, property personnel bonuses, building repairs and maintenance, real estate taxes and insurance, utilities, landscaping and depreciation and amortization. The following table shows our property operating expenses by segment for the three months ended March 31, 2014 and March 31, 2013 (dollars in thousands):

41

	Three months ended March 31,
	2014		2013		Increase		Percentage Increase
Large Market Same Store	$	24,664	$	23,376	$	1,288	5.5	%
Secondary Market Same Store	23,954		23,326		628		2.7	%
Non-Same Store and Other	48,745		3,819		44,926		1,176.4	%
Total	$	97,363	$	50,521	$	46,842	92.7	%

The increase in property operating expenses from our large market same store group is primarily a result of increases in real estate taxes, mulch landscaping expenses, and water and sewer utilities, with real estate taxes being the largest component. The increase in property operating expenses from our secondary market same store group is primarily a result of increases in real estate taxes, interior painting expenses, and water and sewer utilities, with real estate taxes being the largest component. The increase in property operating expenses from our non-same store and other group is primarily due to the addition of the Colonial portfolio as a result of the merger.

Depreciation and Amortization

The following table shows our depreciation and amortization expense by segment for the three months ended March 31, 2014 and March 31, 2013 (dollars in thousands):

	Three months ended March 31,
	2014		2013		Increase/ (Decrease)			Percentage Increase/(Decrease)
Large Market Same Store	$	14,226	$	14,359	$	(133	)	(0.9	)%
Secondary Market Same Store	14,931		15,051		(120		)	(0.8	)%
Non-Same Store and Other	60,856		2,785		58,071			2,085.1	%
Total	$	90,013	$	32,195	$	57,818		179.6	%

The increase in depreciation and amortization expense from our non-same store and other group is primarily due to the addition of the Colonial portfolio as a result of the merger.

General and Administrative 

General and Administrative expense for the three months ended March 31, 2014 was approximately $4.3 million, an increase of $1.1 million from the three months ended March 31, 2013. The majority of the increase was related to increases in stock incentives, SEC filing expenses, and payroll expenses.

Merger and Integration Costs

Merger related expenses for the acquisition of Colonial were approximately $2.1 million for the three months ended March 31, 2014. We also incurred integration related expenses of $3.8 million for the three months ended March 31, 2014. There were no merger related expenses or integration related expenses for the three months ended March 31, 2013.

Interest Expense

Interest expense for the three months ended March 31, 2014 was approximately $30.7 million, an increase of $15.1 million from the three months ended March 31, 2013. The increase was primarily the result of an increase in our average debt outstanding from the three months ended March 31, 2013 to the three months ended March 31, 2014 of approximately $1.77 billion, due primarily to the assumption of Colonial's debt as a result of the Merger.

Discontinued Operations

Income from discontinued operations before gain on sale for the three months ended March 31, 2014 was approximately $0.4 million, a decrease of $1.4 million from the three months ended March 31, 2013. The decrease is driven by

42

the fact that the properties included in discontinued operations had lower net income during the three months ended March 31, 2014 as compared to the three months ended March 31, 2013.

We recorded a gain on sale of discontinued operations of $5.5 million for the three months ended March 31, 2014. There was no gain or loss on sale of discontinued operations for the three months endedMarch 31, 2013. The increase in the gain is caused by the proceeds being greater than the net book value of the properties during the three months ended March 31, 2014 and the fact that there were no property sales during the three months ended March 31, 2013.

Net Income Attributable to MAA

Primarily as a result of the foregoing, net income attributable to MAA decreased by approximately $6.3 million for the three months ended March 31, 2014 from the three months ended March 31, 2013.

Funds from Operations

Funds from operations, or FFO, represents net income (computed in accordance with GAAP) excluding extraordinary items, net income attributable to noncontrolling interest, asset impairment, gains or losses on disposition of depreciable real estate assets, plus depreciation and amortization of real estate, and adjustments for joint ventures to reflect FFO on the same basis. Disposition of real estate assets includes sales of discontinued operations.

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. We believe that FFO is helpful to investors in understanding our operating performance 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. Our calculation of FFO may differ from the methodology for calculating FFO utilized by other REITs and, accordingly, may not be comparable to such other REITs.

Core FFO represents FFO excluding certain non-cash or non-routine items such as acquisition, merger and integration expenses, mark-to-market debt adjustments and loss or gain on debt extinguishment. While our definition of Core FFO is similar to others in our industry, our precise methodology for calculating Core FFO may differ from that utilized by other REITs and, accordingly, may not be comparable to such other REITs. Core FFO should not be considered as an alternative to net income. MAA believes that Core FFO is helpful in understanding our operating performance in that it removes certain items that by their nature are not comparable over periods and therefore tend to obscure actual operating performance.

43

The following table is a reconciliation of Core FFO and FFO to consolidated net income for the three months ended March 31, 2014 and March 31, 2013 (dollars in thousands): 

	Three months ended March 31,
	2014			2013
Net income available for MAA common shareholders	$	14,866		$	21,180
Depreciation and amortization of real estate assets	89,450			31,603
Depreciation and amortization of real estate assets of discontinued operations	42			1,231
Gain on sales of discontinued operations	(5,481		)	—
Gain on sale of depreciable assets excluded from discontinued operations	(2,564		)	—
Depreciation and amortization of real estate assets of real estate joint ventures	199			380
Net income attributable to noncontrolling interests	848			825
Funds from operations	97,360			55,219
Acquisition expense	11			10
Merger related expenses	2,076			—
Integration related expenses	3,842			—
Gain on sale of non-depreciable assets	(557		)	—
Mark-to-market debt adjustment	(7,141		)	(226		)
Loss on debt extinguishment	—			169
Core funds from operations	$	95,591		$	55,172

FFO for the three months ended March 31, 2014 increased approximately $42.1 million from the three months ended March 31, 2013 primarily as a result of the increase in total property revenues of approximately $115.6 million discussed above that was only partially offset by the $46.8 million increase in property operating expenses as well as the $2.1 million in merger related expenses and $15.1 million of increased interest expense.

Core FFO for the three months ended March 31, 2014 increased approximately $40.4 million from the three months ended March 31, 2013 primarily as a result of the increase in total property revenues of approximately $115.6 million discussed above that was only partially offset by the $46.8 million increase in property operating expenses as well as the $15.1 million of increased interest expense.

Trends

During the three months ended March 31, 2014, rental demand for apartments was strong, as it was during the three months ended March 31, 2013. This strength was evident on two fronts: same store average physical occupancy during the three months ended March 31, 2014 was strong, ending the quarter at almost 96% occupancy and averaging in excess of 95% for the quarter; while same store effective rent per unit continued to grow, up 3.4% in the three months ended March 31, 2014 as compared to the three months ended March 31, 2013. We have maintained this momentum despite job formation, one of the primary drivers of apartment demand, continuing to increase at a slower pace than a typical growth cycle.

An important part of our portfolio strategy is to maintain a broad diversity of markets across the Sunbelt region of the United States. The diversity of markets tends to mitigate exposure to economic issues in any one geographic market or area. We believe that a well-diversified portfolio, including both large and select secondary markets, will perform well in “up” cycles as well as weather “down” cycles better. As of March 31, 2014, we were invested in approximately 48 defined Metropolitan Statistical Areas, with approximately 63% of our multifamily assets, based on gross assets, in large markets and 37% of our multifamily assets in select secondary markets.

New supply of rental units entering the market remained below peak new supply delivery averages, but multifamily permitting did pick up in 2013 and has continued into 2014. We believe this permitting will ultimately lead to an increase in supply but also believe the lack of new apartments in recent years combined with demand from new households will help keep supply and demand in balance. Also, we believe that more sustainable credit terms for residential mortgages should work to favor rental demand at existing multi-family properties. Competition from condominiums reverting back to rental units, or new condominiums being converted to rental, has not been a major factor in our portfolio because most of our submarkets have not been primary areas for condominium development. We have found the same to be true for rental competition from single

44

family homes. We have avoided committing a significant amount of capital to markets or submarkets where most of the excessive inflation in house prices occurred. We saw significant rental competition from condominiums or single family houses 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 build apartment rental demand for our markets.

Our focus continues to be on increasing pricing where possible through our revenue management system, while maintaining strong physical occupancy. As noted above, physical occupancy remained strong while effective rents continued to grow. As we move into the spring and summer leasing season, which typically produces more leasing traffic than other parts of the year, physical occupancy is strong. This will enable us to maximize the market's pricing potential in the second quarter of 2014.

We continue to develop improved products, operating systems and procedures that we believe enable us to capture more revenues. The continued benefit of ancillary services (such as our cable saver and deposit saver programs), improved collections and utility reimbursements enable us to capture increased revenue. We also actively work on improving processes and products to reduce expenses, such as new web-sites and internet access for our residents that enable them to transact their business with us more simply and effectively.

Liquidity and Capital Resources

Net cash flow provided by operating activities increased to $113.8 million for the three months ended March 31, 2014 from $42.1 million for the three months ended March 31, 2013. This change was a result of various items, including higher revenue as discussed above.

Net cash provided by investing activities was approximately $12.3 million during the three months ended March 31, 2014 compared to $51.2 million used in investing activities during the three months ended March 31, 2013 due to the factors discussed below. In the three months ended March 31, 2014, we had acquisition cash outflows of $49.5 million compared to $32.6 million for the three months ended March 31, 2013. During three months ended March 31, 2014, we had cash outflows of $16.3 million for development activities, compared to $12.2 million for the three months ended March 31, 2013. During the three months ended March 31, 2014, we also had cash outflows of $1.4 million for improvements to existing real estate assets compared to $2.2 million for the three months ended March 31, 2013. The cash outflows from investing activities were offset by an increase in cash inflows from disposition activity. During the three months ended March 31, 2014, we had cash inflows of approximately $93.1 million, which were related to the sale of three properties and five outparcels. In the three months ended March 31, 2013, we had minimal cash inflows from property sales.

As of March 31, 2014, we owned 75,009,303 OP Units, comprising a 94.7% limited partnership interest in the Operating Partnership, while the remaining 4,208,526 outstanding OP Units were held by limited partners of the Operating Partnership. Holders of OP Units (other than us and our affiliates) may require us to redeem their OP Units from time to time, in which case we may, at our option, pay the redemption price either in cash (in an amount per OP Unit equal, in general, to the average closing price of our common stock on the New York Stock Exchange over a specified period prior to the redemption date) or by delivering one share of our common stock (subject to adjustment under specified circumstances) for each OP Unit so redeemed. In addition, we have registered the 4,208,526 shares of our common stock, which as of March 31, 2014, were issuable upon redemption of OP Units held by the Operating Partnership's limited partners under the Securities Act of 1933, as amended, so that those shares can be sold freely in the public markets. To the extent that additional OP Units are issued to limited partners of the Operating Partnership, we will likely register the additional shares of common stock issuable upon redemption of those OP Units under the Securities Act of 1933, as amended, so that those shares can also be sold in the public markets. If we issue shares of our common stock upon the redemption of OP Units in our Operating Partnership, sales of substantial amounts of such shares of our common stock, or the perception that these sales could occur, may adversely affect prevailing market prices for our common stock or may impair our ability to raise capital through the sale of our common stock or other equity securities.

Net cash used in financing activities was approximately $93.5 million for the three months ended March 31, 2014 compared to $8.3 million provided by financing activities for the three months ended March 31, 2013. During the three months ended March 31, 2014 we paid $54.7 million in dividends and $3.1 million in distributions to noncontrolling interests compared to $29.4 million of dividends and $1.2 million of distributions paid during the three months ended March 31, 2013. We made $18.0 million in principal payments, $15.4 million of which related to the pay-off of one of our property mortgages, during the three months ended March 31, 2014 compared to $1.4 million of principal payments during the three months ended March 31, 2013. In the three months ended March 31, 2014, we had cash inflows of $0.3 million from proceeds of notes payable compared to zero for the three months ended March 31, 2013. In the three months ended March 31, 2014, we received

45

proceeds of approximately $0.2 million primarily from the issuance of common stock through the optional cash feature of our DRSPP. During the three months ended March 31, 2013, we received proceeds of approximately $22.1 million primarily through our at-the-market program, or ATM, and the DRSPP. In the three months ended March 31, 2014, we had cash outflows of $17.9 million from the net change in credit lines compared to $19.0 million of inflows from the net change in credit lines for the three months ended March 31, 2013.

During three months ended March 31, 2014, we sold no shares of common stock through our ATM. This compares to 325,166 shares of common stock sold for net proceeds of approximately $22.0 million for the three months ended March 31, 2013. As of March 31, 2014, there were 4,134,989 shares outstanding under our ATM.

During the three months ended March 31, 2014, we issued 340 shares for gross proceeds of approximately $23,000 through the direct stock purchase feature of our DRSPP. During the three months ended March 31, 2013, we issued 141 shares for net proceeds of $10,000 through our DRSPP. No discount was offered on these issuances in 2014 or 2013.

The weighted average interest rate at March 31, 2014 for the $3.46 billion of debt outstanding was 3.8%, compared to the weighted average interest rate of 3.6% on $1.7 billion of debt outstanding at March 31, 2013. We utilize both conventional and tax exempt debt to help finance our activities. Borrowings are made through individual property mortgages, company-wide secured and unsecured credit facilities, and private and public unsecured notes. We utilize fixed rate borrowings, interest rate swaps and interest rate caps to manage our current and future interest rate risk. More details on our borrowings can be found in the schedules presented later in this section.

At March 31, 2014, we had secured credit facility relationships with Prudential Mortgage Capital which are credit enhanced by Fannie Mae, Financial Federal which are credit enhanced by the Federal Home Loan Mortgage Corporation, or Freddie Mac, and a $500 million bank unsecured facility with a syndicate of banks. Together, these credit facilities provided a total line capacity of $1.36 billion with all but $231.5 million collateralized and available to borrow at March 31, 2014. We had total borrowings outstanding under these credit facilities of $633.4 million at March 31, 2014.

Approximately 13% of our outstanding obligations at March 31, 2014 were borrowed through credit facilities with/or credit enhanced by Fannie Mae, also referred to as the Fannie Mae Facilities. The Fannie Mae Facilities have a combined line limit of $661.2 million, of which $435.2 million was collateralized and available to borrow at March 31, 2014. We had total borrowings outstanding under the Fannie Mae Facilities of approximately $435.2 million at March 31, 2014. Various Fannie Mae rate traunches of the Fannie Mae Facilities mature from 2014 through 2018. The Fannie Mae Facilities provide for both fixed and variable rate borrowings. The interest rate on the majority of the variable portion is based on the Fannie Mae Discount Mortgage Backed Security, or DMBS, rate which are credit-enhanced by Fannie Mae and are typically sold every 90 days by Prudential Mortgage Capital at interest rates approximating three-month LIBOR less a spread that has averaged 0.17% over the life of the Fannie Mae Facilities, plus a credit enhancement fee of 0.49% to 0.67%. We have seen more volatility in the spread between the DMBS and three-month LIBOR since late 2007 than was historically prevalent.

Approximately 6% of our outstanding obligations at March 31, 2014 were borrowed through a credit facility with or credit enhanced by Freddie Mac, also referred to as the Freddie Mac Facility. The Freddie Mac Facility has a combined line limit of $200.0 million, of which $198.2 million was collateralized and available to borrow at March 31, 2014. We had total borrowings outstanding under the Freddie Mac Facility of approximately $198.2 million at March 31, 2014. The Freddie Mac facility matures in 2014. The interest rate on the Freddie Mac Facility renews every 30 or 90 days and is based on the Freddie Mac Reference Bill Rate on the date of renewal, which has historically approximated the equivalent 30 or 90-day LIBOR, plus a credit enhancement fee of 0.65%. The Freddie Mac Reference Bill rate has traded consistently below LIBOR, and the historical average spread was 0.29% below LIBOR at March 31, 2014.

We also maintain a $500.0 million unsecured credit facility with fourteen banks led by KeyBank National Association (Key Bank). The Key Bank credit facility bears an interest rate of LIBOR plus a spread of 0.90% to 1.70% based on an investment grade pricing grid. This credit facility expires in August 2017 with two separate six-month extension options. At March 31, 2014, we had $496.3 million available to be borrowed under the Key Bank credit facility agreement with zero borrowings under this facility. Approximately $3.7 million of the facility is used to support letters of credit.

Each of our credit facilities is subject to various covenants and conditions on usage, and the secured facilities are subject to periodic re-evaluation of collateral. If we were to fail to satisfy a condition to borrowing, the available credit under one or more of the facilities could not be drawn, which could adversely affect our liquidity. In the event of a reduction in real estate values the amount of available credit could be reduced. Moreover, if we were to fail to make a payment or violate a covenant under a credit facility, after applicable cure periods, one or more of our lenders could declare a default, accelerate the due date for repayment of all amounts outstanding and/or foreclose on properties securing such facilities. A default on an

46

obligation to repay outstanding debt could also create a cross default on a separate piece of debt, whereby one or more of our lenders could accelerate the due date for repayment of all amounts outstanding and/or foreclose on properties securing the related facilities. Any such event could have a material adverse effect.

On August 7, 2013, our Operating Partnership entered into a $500 million unsecured revolving credit facility agreement with KeyBank National Association and thirteen other banks. This agreement amends our Operating Partnership's previous unsecured credit facility with KeyBank. Interest is paid using an investment grade pricing grid using LIBOR plus a spread of 0.90% to 1.70%. As of March 31, 2014, we had no borrowings under this facility.

On October 16, 2013, MAALP issued $350 million in aggregate principal amount of notes, maturing on October 15, 2023 with an interest rate of 4.3% per annum (the "2023 Notes"). The purchase price paid by the initial purchasers was 99.047% of the principal amount. The 2023 Notes are general unsecured senior obligations of MAALP and rank equally in right of payment with all other senior unsecured indebtedness of MAALP. Interest on the 2023 Notes is payable on April 15 and October 15 of each year, beginning on April 15, 2014. The net proceeds from the offering after deducting the original issue discount of approximately $3.3 million and underwriting commissions and expenses of approximately $2.3 million were approximately $344.4 million. The 2023 Notes have been reflected net of discount in the consolidated balance sheet. The Company transacted three swaps totaling $150 million, which resulted in a total effective interest rate of 4.15%.

On December 13, 2013, MAALP completed a series of exchange offers (the “Exchange Offers”) pursuant to which it exchanged $154,235,000 aggregate principal amount of 6.25% Senior Notes due 2014, $169,161,000 aggregate principal amount of 5.50% Senior Notes due 2015 and $68,130,000 aggregate principal amount of 6.05% Senior Notes due 2016 (collectively, the “Existing Notes”) issued by Colonial Realty Limited Partnership, a Delaware limited partnership and wholly owned subsidiary of MAALP, for $154,235,000 aggregate principal amount of MAALP’s new 6.25% Senior Notes due 2014 (the “2014 Notes”), $169,112,000 aggregate principal amount of MAALP’s new 5.50% Senior Notes due 2015 (the “2015 Notes”) and $68,130,000 aggregate principal amount of MAALP’s new 6.05% Senior Notes due 2016 (the “2016 Notes” and together with the 2014 Notes and the 2015 Notes, the “Exchange Notes”), plus approximately $975,000 in cash.

The Exchange Notes are senior unsecured obligations of MAALP and will rank equally in right of payment with all of MAALP’s other existing and future senior unsecured indebtedness. Interest on the 2014 Notes will accrue from, and including, December 15, 2013 and will be payable on June 15, 2014, which will also be the maturity date for the 2014 Notes. Interest on the 2015 Notes will accrue from, and including, October 1, 2013 and will be payable semiannually on April 1 and October 1 of each year, beginning on April 1, 2014. Interest on the 2016 Notes accrued from, and including, September 1, 2013 and was paid on March 1, 2014. Interest payments will be payable semiannually on March 1 and September 1 of each year, beginning on March 1, 2014. In certain circumstances described below MAALP may be required to pay additional interest on the Exchange Notes.

The Indenture under which the 2023 notes were issued and the Indentures contain certain covenants that, among other things, limit the ability of MAALP and its subsidiaries to incur secured and unsecured indebtedness if not in pro forma compliance with the following negative covenants: (1) total leverage not to exceed 60% of adjusted total assets, (2) secured leverage not to exceed 40% of adjusted total assets and (3) a fixed charge coverage ratio of at least 1.50 to 1. In addition, MAALP is required to maintain at all times unencumbered consolidated total assets of not less than 150% of the aggregate principal amount of its outstanding unsecured debt. At March 31, 2014, MAALP was in compliance with each of these financial covenants.

All of the Existing Notes tendered into the Exchange Offers were cancelled in connection with the settlement of the Exchange Offers. In connection with the issuance and sale of the Exchange Notes, MAALP also entered into three separate registration rights agreements, each dated as of December 13, 2013, and each with J.P. Morgan Securities LLC, the dealer manager in the Exchange Offers (the “Registration Rights Agreements”). Under the Registration Rights Agreements, MAALP agreed to use commercially reasonable efforts to complete exchange offers registered under the Securities Act pursuant to which MAALP will offer to issue new exchange notes containing terms substantially similar in all material respects to the Exchange Notes (except that the exchange notes will not contain terms with respect to transfer restrictions or any increase in annual interest rate) in exchange for the Exchange Notes. MAALP also agreed, if it determines that a registered exchange offer is not available or specified other circumstances occur, to use commercially reasonable efforts to file and have become effective a shelf registration statement relating to resales of the Exchange Notes. MAALP will be obligated to pay additional interest of up to 0.50% per annum on the Exchange Notes if it does not complete the exchange offers within 270 days after the issue date of the Exchange Notes and in other specified circumstances.

On October 1, 2013, we acquired the Colonial term loan agreements with Wells Fargo and U.S. Bank Association of $250 million and $150 million, respectively. The Wells Fargo term loan bears interest at a rate of LIBOR plus a spread of

47

1.65% to 2.90% based on the credit ratings of our unsecured debt from time to time and matures on August 1, 2018. The U.S. Bank National Association term loan bears interest at a rate of LIBOR plus a spread of 1.10% to 2.05% based on the credit ratings of our unsecured debt from time to time and matures on May 11, 2017. Including our term loan agreement with Key Bank and J.P. Morgan, we had total borrowings of $550 million outstanding under these term loan agreements at March 31, 2014.

As of March 31, 2014, we had entered into interest rate swaps totaling a notional amount of $717.0 million. 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 approximately $314.3 million as of March 31, 2014.

The following schedule outlines our variable versus fixed rate debt, including the impact of interest rate swaps and caps, outstanding as of March 31, 2014 (dollars in thousands):

We believe that we have adequate resources to fund our current operations, annual refurbishment of our properties, and incremental investment in new apartment properties. We rely on the efficient operation of the financial markets to refinance debt maturities, and on rate renewals for Fannie Mae and Freddie Mac, or the Agencies. The Agencies provided credit enhancement for approximately $633.4 million of our outstanding debt through credit facilities as of March 31, 2014.

48

The interest rate markets for Fannie Mae DMBS and Freddie Mac Reference Bills, which in our experience are highly liquid and highly correlated with three-month LIBOR interest rates, are also an important component of our liquidity and interest rate swap effectiveness. Prudential Mortgage Capital, a Delegated Underwriting and Servicing (DUS) lender for Fannie Mae, markets 90-day Fannie Mae Discount Mortgage Backed Securities monthly, and is obligated to advance funds to us at DMBS rates plus a credit spread under the terms of the credit agreements between Prudential and us. Financial Federal, a Freddie Mac Program Plus Lender and Servicer, is obligated to advance funds under the terms of credit agreements between Financial Federal and us.

For the quarter ended March 31, 2014, our net cash provided by operating activities was in excess of covering funding of normal capital improvements to existing real estate assets, distributions to unitholders, and dividends paid on common and preferred shares by approximately $45.6 million, as compared to $2.8 million for the same period in 2013. While we had sufficient liquidity to permit 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 shareholders at the current rate, in which event we would be required to reduce the distribution rate.

The following table reflects our total contractual cash obligations which consist of our long-term debt, development fees and operating leases as of March 31, 2014 (dollars in thousands):

Contractual Obligations (1)	2014		2015		2016		2017		2018		Thereafter		Total

Off-Balance Sheet Arrangements

At March 31, 2014, and 2013, we did not have any relationships with unconsolidated entities or financial partnerships established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Mid-America Multifamily Fund I, LLC, was established to acquire $500 million of apartment communities with redevelopment upside offering value creation opportunity through capital improvements, operating enhancements and restructuring in-place financing. As of March 31, 2014, Mid-America Multifamily Fund I, LLC was legally dissolved and owned zero properties. Mid-America Multifamily Fund II, LLC, was established to acquire $250 million of apartment communities with redevelopment upside offering value creation opportunity through capital improvements, operating enhancements and restructuring in-place financing. As of March 31, 2014, Mid-America Multifamily Fund II, LLC owned two properties. 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 Item 8. Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements, Note 17 in our Annual Report on Form 10-K filed with the SEC on February 21, 2014.

Our investments in our real estate joint ventures are unconsolidated and are recorded using the equity method for the joint ventures in which we do not have a controlling interest.

49

Insurance

We renegotiated our insurance programs effective July 1, 2013. We believe that the property and casualty insurance program in place provides appropriate insurance coverage for financial protection against insurable risks such that any insurable loss experienced that can be reasonably anticipated would not have a significant impact on our liquidity, financial position or results of operation.

Inflation

Our resident leases at 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

In April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 raises the threshold for disposals to qualify as discontinued operations. It also requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. The ASU is effective for fiscal years beginning after December 15, 2014, and interim periods within those years; however, early adoption is permitted beginning in the first quarter of 2014. We adopted ASU 2014-08 during the period ending March 31, 2014. The adoption of ASU 2014-08 required us to not classify certain disposals occurring during the first quarter of 2014 as discontinued operations.

In January 2013, the FASB issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. ASU 2013-01 clarifies that the scope of ASU 2011-11, Disclosures about Offsetting Assets and Liabilities, would apply to derivatives accounted for in accordance with FASB ASC 815, Derivatives and Hedging, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with ASC 210-20-45 or ASC 815-10-45 or subject to an enforceable master netting arrangement or similar agreement. This ASU is effective for fiscal years beginning on or after January 1, 2013 and interim periods within those annual periods. We adopted ASU 2013-01 during the period ended March 31, 2013. The adoption of ASU 2013-01 has not had a material impact on our consolidated financial condition or results of operations taken as a whole.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to interest rate changes associated with our credit facilities and other variable rate debt as well as refinancing risk on our fixed rate debt. Our involvement with derivative financial instruments is limited to managing our exposure to changes in interest rates and we do not expect to use them for trading or other speculative purposes.

There have been no material changes in our market risk as disclosed in the Annual Report on Form 10-K filed with the SEC on February 21, 2014.

Item 4.   Controls and Procedures.

Management’s Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive and financial officers, has evaluated the effectiveness of our disclosure controls and procedures in ensuring that the information required to be disclosed in our filings under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, including ensuring that such information is accumulated and communicated to our management as appropriate to allow timely decisions regarding required disclosure. Based on such evaluation, our principal executive and financial officers have concluded that such disclosure controls and procedures were effective as of March 31, 2014 (the end of the period covered by this Quarterly Report on Form 10-Q).

Changes in Internal Controls

During the quarter ended March 31, 2014, there were no changes in our internal control over financial reporting that materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1.      Legal Proceedings.

The Company (by virtue of its merger with Colonial) and Colonial LP along with multiple other parties, are named defendants in lawsuits arising out of alleged construction deficiencies with respect to condominium units at Regatta at James Island in Charleston, South Carolina. Regatta at James Island property was developed by certain of the Company's subsidiaries and constructed by Colonial Construction Services, LLC. The condominiums were constructed in 2006 and all 212 units were sold. The lawsuits, one filed on behalf of the condominium homeowners association and one filed by three of the unit owners (purportedly on behalf of all unit owners), were filed in South Carolina state court (Charleston County) in August 2012, against various parties involved in the development and construction of the Regatta at James Island property, including the contractors, subcontractors, architect, developer, and product manufacturers. The plaintiffs are seeking damages resulting primarily from alleged construction deficiencies, but the amount plaintiffs seek to recover has not been disclosed. The lawsuits are currently in discovery. The Company is continuing to investigate the matter and evaluate its options and intends to vigorously defend itself against these claims. No assurance can be given that the matter will be resolved favorably to the Company. The Companyhas included in its loss contingency an estimate of probable loss in connection with this matter, but currently cannot reasonably estimate any further possible loss, or any range of reasonably possible loss, in connection with this matter.

The Company (by virtue of its merger with Colonial) and Colonial LP along with multiple other parties, are named defendants in a lawsuit arising out of alleged construction deficiencies with respect to condominium units at Plantation Point in Bluffton, South Carolina. Plantation Point was previously owned and operated by Colonial LP as a multi-family rental project by the name of the Ashley Plantation apartments. Colonial LP sold the property in 2005 to a third party, which then converted the property to condominiums and sold all 414 units. The lawsuit, filed on behalf of the condominium homeowners association and a class of unit owners, was filed in South Carolina state court (Beaufort County) in September 2011, against various parties involved in the development, construction and conversion of the Plantation Point property, including the contractors, subcontractors, architect, developer, and product manufacturers. The plaintiffs are seeking $24.7 million in damages resulting from, among other things, alleged construction deficiencies and misleading sales practices attributed to the third-party seller. The lawsuit is currently in discovery. The Company is continuing to investigate the matter and evaluate its options and intends to vigorously defend itself against these claims. No assurance can be given that the matter will be resolved favorably to the Company. The Company has included in its loss contingency an estimate of probable loss in connection with this matter, but currently cannot reasonably estimate any further possible loss, or any range of reasonably possible loss, in connection with this matter.

On June 19, 2013, a putative class action was filed in the Circuit Court for Jefferson County, Alabama captioned Williams v. Colonial Properties Trust, et al., No. 01-CV-2013-902416.00 (the “Williams Litigation”), seeking, among other things, to enjoin the previously announced combination of MAA and Colonial in accordance with the terms of the Agreement and Plan of Merger, dated June 3, 2013, by and among MAA, the Operating Partnership, Martha Merger Sub, LP, Colonial and Colonial LP. On March 6, 2014 the Court approved the final settlement of the Williams litigation and the Company made the Court-approved immaterial payment to the Plaintiff's attorneys.

In addition, the Company is subject to various other legal proceedings and claims that arise in the ordinary course of its business operations. Matters which arise out of allegations of bodily injury, property damage, and employment practices are generally covered by insurance. While the resolution of these other matters cannot be predicted with certainty, management currently believes the final outcome of such matters will not have a material adverse effect on the financial position, results of operations or cash flows of the Company.

Loss Contingencies

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

The assessment of whether a loss is probable or a reasonable possibility, and whether the loss or range of loss is reasonably estimable, often involve a series of complex judgments about future events. Among the factors that the Company considers in this assessment, including with respect to the matters disclosed, are the nature of existing legal proceedings and

51

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, the Company's experience in similar matters, the facts available to the Company at the time of assessment, and how the Company intends to respond, or has responded, to the proceeding or claim. The Company's assessment of these factors may change over time as individual proceedings or claims progress. For matters where the Company is not currently able to reasonably estimate a range of reasonably possible loss, the factors that have contributed to this determination include the following: (i) the damages sought are indeterminate, (ii) the proceedings are in the early stages, (iii) the matters involve novel or unsettled legal theories or a large or uncertain number of actual or potential cases or parties, and/or (iv) discussions with the parties in matters that are expected ultimately to be resolved through negotiation and settlement have not reached the point where the Company believes a reasonable estimate of loss, or range of loss, can be made. In such instances, the Company believes that there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss or business impact, if any.

Item 1A.   Risk Factors.

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

Risks relating to the Colonial Merger

We have incurred and expect to incur substantial expenses related to the Merger.

We have incurred and expect to incur substantial expenses in connection with the Merger and integrating Colonial’s business, operations, networks, systems, technologies, policies and procedures with ours. There are a large number of systems that are in the process of being integrated, including property management, revenue management, resident payment, credit screening, lease administration, website content management, purchasing, accounting, payroll, fixed assets and financial reporting. Moreover, there are a number of factors beyond our control that could affect the total amount or the timing of these integration expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time. As a result, expenses associated with the Merger could, particularly in the near term, exceed the savings that we expect to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings related to the integration of the businesses.

We may be unable to integrate Colonial’s businesses with ours successfully or realize the anticipated synergies and other benefits of the Merger or do so within the anticipated timeframe.

Because Colonial was a public company, we expect to benefit from the elimination of duplicative costs associated with supporting Colonial’s public company platform and the leveraging of our technology and systems. These savings are expected to be realized upon full integration, which is expected to occur over the 18-month period following the closing of the Merger. However, we are required to devote significant management attention and resources to integrating the business practices and operations of Colonial with our business practices and operations. Potential difficulties we may encounter in the integration process include the following:

• the inability to successfully combine the businesses of Colonial with ours in a manner that permits us to achieve the cost savings anticipated to result from the Merger, which would result in the anticipated benefits of the Merger not being realized in the time frame currently anticipated or at all;

• the complexities associated with managing the combined businesses out of several different locations and integrating personnel from the two companies;

• the additional complexities of combining two companies with different histories, cultures, regulatory restrictions, markets and customer bases;

• potential unknown or unforeseen liabilities, increased expenses, delays or regulatory conditions associated with Colonial, Colonial LP or the Merger; and

• performance shortfalls as a result of the diversion of management’s attention caused by integrating Colonial’s operations with our operations.

52

For all these reasons, you should be aware that it is possible that the integration process could result in the distraction of our management, the disruption of our ongoing business or inconsistencies in our operations, services, standards, controls, procedures and policies, any of which could adversely affect our ability to maintain relationships with tenants, vendors and employees or to achieve the anticipated benefits of the Merger, or could otherwise adversely affect our business, results of operations, financial condition and prospects.

We may be unable to retain key employees as a result of the Merger.

Our success will depend in part upon the ability to retain key former employees of Colonial, as well as our key employees. Key employees may depart because of, among other things, issues relating to the combination of the two companies, uncertainty and difficulty of integration or a desire not to remain with us following the Merger. Accordingly, no assurance can be given that we will be able to retain key employees to the same extent as in the past.

The Merger resulted in changes to MAA's board of directors that may affect our strategy going forward.

The composition of MAA's board of directors changed as a result of the Merger. MAA's board of directors now consists of twelve members, including all seven directors from MAA's board of directors prior to the Merger and five directors who were members of the Colonial board of trustees prior to the Merger. This new composition of MAA's board of directors may affect our business strategy and operations going forward.

Our future results will suffer if we do not effectively manage our expanded operations following the Merger.

We have expanded our operations as a result of the Merger and intend to continue to expand our operations through additional acquisitions of properties, some of which may involve complex challenges. Our future success will depend, in part, upon our ability to manage the integration of the Colonial operations and our expansion opportunities, each of which may pose substantial challenges for us to integrate new operations into our existing business in an efficient and timely manner, and upon our ability to successfully monitor our operations, costs, regulatory compliance and service quality, and to maintain other necessary internal controls. There is no assurance that our expansion or acquisition opportunities will be successful, or that we will realize any operating efficiencies, cost savings, revenue enhancements, synergies or other benefits from any future acquisitions we may complete.

We may incur adverse tax consequences if Colonial failed to qualify as a REIT for U.S. federal income tax purposes; and if that occurs, it may have a material adverse effect on our consolidated results of operations and financial condition.

Prior to the Merger, Colonial operated in a manner intended to allow it to qualify as a REIT for U.S. federal income tax purposes under the Code. As discussed in Exhibit 99.1 to our Current Report on Form 8-K filed with the SEC on February 27, 2014, qualification as a REIT involves the application of highly technical and complex Code provisions for which there are only limited judicial and administrative interpretations and Colonial’s qualification as a REIT prior to the Merger was generally subject to the same requirements, risks and uncertainties as described in such Exhibit 99.1. Moreover, the complexity of these provisions and of the applicable Treasury Regulations that have been promulgated under the Code is greater in the case of a REIT that holds its assets through a partnership (such as we do and Colonial did prior to the Merger). The determination of various factual matters and circumstances not entirely within a REIT’s control may affect its ability to qualify as a REIT.

If Colonial is determined to have lost its REIT status at any time prior to the Merger, MAA will face serious tax consequences and material tax liabilities. Because MAA owns no material assets other than its ownership interest in the Operating Partnership, the Operating Partnership and its subsidiaries would likely be required to provide cash to MAA to satisfy any such tax liabilities, which would substantially reduce the Operating Partnership’s available cash, including cash available to pay its indebtedness or make distributions to its limited partners or MAA's shareholders because, among other things:

• MAA would be required to pay U.S. federal income tax on Colonial’s prior net income at regular corporate rates for the years it did not qualify for taxation as a REIT (and, for such years, Colonial would not be allowed a deduction for dividends paid to its former shareholders in computing its taxable income);

• Colonial could be subject to the federal alternative minimum tax and possibly increased state and local taxes for such periods; and

• Unless Colonial is entitled to relief under applicable statutory provisions, neither it nor any “successor” company could elect to be taxed as a REIT until the fifth taxable year following the year during which it was disqualified.

53

MAA is liable for any taxes payable by Colonial for any periods prior to the Merger. In addition, if Colonial failed to qualify as a REIT but we nonetheless qualified as a REIT, in the event of a taxable disposition of a former Colonial asset during the ten years following the Merger we would be subject to corporate tax with respect to any built-in gain inherent in such asset as of the date of the Merger. In addition, under the “investment company” rules under Section 368 of the Code, if both MAA and Colonial were “investment companies” under such rules, the failure of either Colonial or us to have qualified as a REIT could cause the Merger to be taxable to us and our shareholders. As a result of all these factors, Colonial’s failure to have qualified as a REIT could jeopardize our qualification as a REIT and require our Operating Partnership to provide material amounts of cash to us to satisfy our additional tax liabilities and therefore have a material adverse effect on our financial condition, results of operations, business and prospects and our ability to make payments on our indebtedness or distributions to our shareholders.

Risks Related to Our Real Estate Investments and Our Operations

Economic slowdown in the United States and downturns in the housing and real estate markets may adversely affect our financial condition and results of operations.

There have been significant declines in economic growth, both in the United States and globally. Both the real estate industry and the broader United States economy have experienced unfavorable conditions, which adversely affected our business. Factors such as weakened economies and related reduction in spending, falling home prices and job losses, price volatility, and/or dislocations and liquidity disruptions in the financial and credit markets could, among other things, impede the ability of our tenants and other parties with which we conduct business to perform their contractual obligations, which could lead to an increase in defaults by our tenants and other contracting parties, which could adversely affect our revenues. Furthermore, our ability to lease our properties at favorable rates, or at all, could be adversely affected by increases in supply and deterioration in multifamily markets and is partially dependent upon the overall level of spending in the economy, which is adversely affected by, among other things, job losses and unemployment levels, recession, personal debt levels, downturns in the housing market, stock market volatility and uncertainty about the future. With regard to our ability to lease our multifamily properties, the increasing rental of excess for-sale condominiums and single family homes, which increases the supply of multifamily units and housing alternatives, may reduce our ability to lease our multifamily units and depress rental rates in certain markets. When we experience a downturn, we cannot predict how long demand and other factors in the real estate market will remain unfavorable, but if the markets remain weak over extended periods of time or deteriorate significantly, our ability to lease our properties or our ability to increase or maintain rental rates in certain markets may weaken, which would adversely affect our revenues.

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

Our ability to make payments on our debt and to make distributions depends on our ability to generate cash flow in excess of operating costs and capital expenditure requirements and/or to have access to the markets for debt and equity financing. Funds from operations and the value of our apartment communities may be insufficient because of factors that are beyond our control. Such events or conditions could include:

• competition from other apartment communities;

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

• conversion of condominiums and single family houses to rental use;

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

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

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

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

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

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

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

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

• changes in interest rate levels and the availability of financing, borrower credit standards, and down-payment requirements which could lead renters to purchase homes (if interest rates decrease and home loans are more readily

54

available) or increase our acquisition and operating costs (if interest rates increase and financing is less readily available); and

• the relative illiquidity of real estate investments.

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

Our operations are concentrated in the Sunbelt Region of the United States, in particular the state of Texas; we are subject to general economic conditions in the regions in which we operate.

Approximately 39.9% of our portfolio is centered in our top six markets: Austin, Texas; Atlanta, Georgia; Charlotte, North Carolina; Raleigh/Durham, North Carolina; Dallas, Texas; and Fort Worth, Texas. Our performance could be adversely affected by economic conditions in, and other factors relating to, these geographic areas, including supply and demand for apartments in these areas, zoning and other regulatory conditions and competition from other communities and alternative forms of housing. In particular our performance is disproportionately influenced by job growth and unemployment. To the extent the aforementioned general economic conditions, job growth and unemployment in any of these markets deteriorate or any of these areas experiences natural disasters, the value of the portfolio, our results of operations and our ability to make distributions to our shareholders and pay amounts due on our debt could be materially adversely affected.

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

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

We may be adversely affected by new laws and regulations.

The current United States administration and Congress have enacted, or called for consideration of, proposals relating to a variety of issues, including with respect to health care, financial regulation reform, climate control, executive compensation and others. We believe that these and other potential proposals could have varying degrees of impact on us ranging from minimal to material. At this time, we are unable to predict with certainty what level of impact specific proposals could have on us.

Certain rulemaking and administrative efforts that may have an impact on us focus principally on the areas perceived as contributing to the global financial crisis and the continuing economic downturn. These initiatives have created uncertainty regarding the basic rules governing the real estate industry and many other businesses. The federal legislative response in this area culminated in the enactment on July 21, 2010 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act. Many of the provisions of the Dodd-Frank Act have extended implementation periods and delayed effective dates and will require extensive rulemaking by regulatory authorities; thus, the impact on us may not be known for an extended period of time. The Dodd-Frank Act, including future rules implementing its provisions and the interpretation of those rules, along with other legislative and regulatory proposals that are proposed or pending in the United States Congress, may limit our revenues, impose fees or taxes on us, and/or intensify the regulatory framework in which we operate in ways that are not currently identifiable.

Changing laws, regulations and standards relating to corporate governance and public disclosure in particular, including certain provisions of the Dodd-Frank Act and the rules and regulations promulgated thereunder, have created uncertainty for public companies like ours and could significantly increase the costs and risks associated with accessing the United States public markets. Because we are committed to maintaining high standards of internal control over financial reporting, corporate governance and public disclosure, our management team will need to devote significant time and financial

55

resources to comply with these evolving standards for public companies. We intend to continue to invest appropriate resources to comply with both existing and evolving standards, and this investment has resulted and will likely continue to result in increased general and administrative expenses and a diversion of management time and attention from revenue generating activities to compliance activities.

Breaches of our data security could materially harm our business and reputation.

We collect and retain certain personal information provided by our tenants and employees. While we have implemented a variety of security measures to protect the confidentiality of this information and periodically review and improve our security measures, there can be no assurance that we will be able to prevent unauthorized access to this information. Any breach of our data security measures and loss of this information may result in legal liability and costs(including damages and penalties), as well as damage to our reputation, that could materially and adversely affect our business and financial performance.

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

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

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

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

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

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

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

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

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

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

• a significant portion of the proceeds from our overall property sales may be held by intermediaries in order for some sales to qualify as like-kind exchanges under Section 1031 of the Code, so that any related capital gain can be deferred for federal income tax purposes. As a result, we may not have immediate access to all of the cash proceeds generated from our property sales; and

• federal tax laws limit our ability to profit on the sale of communities that we have owned for less than two years, and this limitation may prevent us from selling communities when market conditions are favorable.

Environmental problems are possible and can be costly.

Under various federal, state and local laws, ordinances and regulations, a current or previous owner or operator of real estate may be liable for the costs of removal or remediation of certain hazardous or toxic substances in, on, around or under such property. Such laws often impose such liability without regard to whether the owner or operator knew of, or was

56

responsible for, the presence of such hazardous or toxic substances. The presence of, or failure to remediate properly, hazardous or toxic substances may adversely affect the owner’s or operator’s ability to sell or rent the affected property or to borrow using the property as collateral. Persons who arrange for the disposal or treatment of hazardous or toxic substances may also be liable for the costs of removal or remediation of hazardous or toxic substances at a disposal or treatment facility, whether or not the facility is owned or operated by the person. Certain environmental laws impose liability for release of asbestos-containing materials into the air, and third parties may also seek recovery from owners or operators of real property for personal injury associated with asbestos-containing materials and other hazardous or toxic substances. Federal and state laws also regulate the operation and subsequent removal of certain underground storage tanks. In connection with the current or former ownership (direct or indirect), operation, management, development or control of real property, we may be considered an owner or operator of such communities or as having arranged for the disposal or treatment of hazardous or toxic substances and, therefore, may be potentially liable for removal or remediation costs, as well as certain other costs, including governmental fines, and claims for injuries to persons and property.

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

• all or the full extent of potential environmental liabilities;

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

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

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

Certain environmental laws impose liability on a previous owner of property to the extent that hazardous or toxic substances were present during the prior ownership period. A transfer of the property does not relieve an owner of such liability. Thus, we may have liability with respect to communities previously sold by our predecessors or by us.

There have been a number of lawsuits against owners and managers of multifamily communities alleging personal injury and property damage caused by the presence of mold in residential real estate. Some of these lawsuits have resulted in substantial monetary judgments or settlements. Insurance carriers have reacted to these liability awards by excluding mold related claims from standard policies and pricing mold endorsements separately. We have obtained a separate pollution insurance policy that covers mold-related claims and have adopted programs designed to minimize the existence of mold in any of our communities as well as guidelines for promptly addressing and resolving reports of mold. To the extent not covered by our pollution policy, the presence of mold could expose us to liability from residents and others if property damage, health concerns, or allegations thereof, arise.

Changes in the system for establishing United States accounting standards may materially and adversely affect our reported results of operations.

Accounting for public companies in the United States has historically been conducted in accordance with GAAP. GAAP is established by the Financial Accounting Standards Board, or FASB, an independent body whose standards are recognized by the SEC as authoritative for publicly held companies. The International Accounting Standards Board, or IASB, is a London-based independent board established in 2001 and charged with the development of International Financial Reporting Standards, or IFRS. IFRS generally reflects accounting practices that prevail in Europe and in developed nations around the world.

IFRS differs in material respects from GAAP. Among other things, IFRS has historically relied more on “fair value” models of accounting for assets and liabilities than GAAP. “Fair value” models are based on periodic revaluation of assets and liabilities, often resulting in fluctuations in such values as compared to GAAP, which relies more frequently on historical cost as the basis for asset and liability valuation.

It is unclear at this time if or how the SEC will transition from GAAP to IFRS. Switching to a new method of accounting and adopting IFRS will be a complex undertaking. We may need to develop new systems and controls based on the principles of IFRS. Since these are new endeavors, and the precise requirements of the pronouncements ultimately adopted are not now known, the magnitude of costs associated with this conversion is uncertain. We are currently evaluating the impact of the adoption of IFRS on our financial position and results of operations. Such evaluation cannot be completed, however, without more clarity regarding the specific IFRS standards that will be adopted. Until there is more certainty with respect to the

57

IFRS standards to be adopted, prospective investors should consider that our conversion to IFRS could have a material adverse effect on our reported results of operations.

Losses from catastrophes may exceed our insurance coverage.

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

Increasing real estate taxes and insurance costs may negatively impact operating results.

As a result of our substantial real estate holdings, the cost of real estate taxes and insuring our apartment communities is a significant component of expense. Real estate taxes and insurance premiums are subject to significant increases and fluctuations, which can be widely outside of our control. If the costs associated with real estate taxes and insurance should rise, our financial condition could be negatively impacted, and our ability to pay our dividend could be affected.

We may experience increased costs arising from health care reform.

In March 2010, the United States government enacted comprehensive health care reform legislation which, among other things, includes guaranteed coverage requirements, eliminates pre-existing condition exclusions and annual and lifetime maximum limits, restricts the extent to which policies can be rescinded and imposes new and significant taxes on health insurers and health care benefits. The legislation imposes implementation effective dates extending through 2020, and many of the changes require additional guidance from government agencies or federal regulations. Therefore, due to the phased-in nature of the implementation and the lack of interpretive guidance, in some cases, it is difficult to determine at this time what impact the health care reform legislation will have on our financial results. Possible adverse effects of the health reform legislation include increased costs, exposure to expanded liability and requirements for us to revise ways in which we provide healthcare and other benefits to our employees. In addition, our results of operations, financial position and cash flows could be materially adversely affected.

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

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

Development and construction risks could impact our profitability.

As of March 31, 2014, we had four development communities under construction totaling 999 units. We have completed 305 units for the development projects as of March 31, 2014.  Our development and construction activities are subject to the following risks:

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

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

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

58

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

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

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

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

Risks Related to Our Indebtedness and Financing Activities

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

As of March 31, 2014, the amount of our total debt was approximately $3.46 billion. We may incur additional indebtedness in the future in connection with, among other things, our acquisition, development and operating activities.

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

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

• we may be subject to prepayment penalties if we elect to repay our indebtedness prior to the stated maturity date;

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

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

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

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

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

We may be unable to renew, repay or refinance our outstanding debt.

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

Rising interest rates would increase the cost of our variable rate debt.

We have incurred and expect in the future to incur indebtedness that bears interest at variable rates. Accordingly, increases in interest rates would increase our interest costs, which could have a material adverse effect on us and our ability to make distributions to our shareholders and pay amounts due on our debt or cause us to be in default under certain debt instruments. In addition, an increase in market interest rates may lead holders of our shares of common stock to demand a higher yield on their shares from distributions by us, which could adversely affect the market price for our common stock.

We may incur additional debt in the future.

We currently fund the acquisition and development of multifamily apartment communities partially through borrowings (including our revolving credit facility) as well as from other sources such as sales of communities which no longer meet our investment criteria. Our organizational documents do not contain any limitation on the amount of indebtedness that

59

we may incur. Accordingly, subject to limitations on indebtedness set forth in various loan agreements and the indentures governing our senior notes, we could become more highly leveraged, resulting in an increase in debt service, which could have a material adverse effect on us and our ability to make distributions to our shareholders and pay amounts due on our debt and in an increased risk of default on our obligations.

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

At March 31, 2014, we had outstanding borrowings of approximately $3.46 billion. Our indebtedness contains financial covenants as to minimum net worth, interest coverage ratios, maximum secured debt, and total debt to capital, among others. In the event that an event of default occurs, our lenders may declare borrowings under the respective loan agreements to be due and payable immediately, which could have a material adverse effect on us and our ability to make distributions to our shareholders and pay amounts due on our debt.

A change in United States government policy with regard to Fannie Mae and Freddie Mac could impact our financial condition.

Fannie Mae and Freddie Mac are a major source of financing for multifamily real estate in the United States. We utilize loan programs sponsored by these entities as one source of capital to finance our growth and our operations. On February 11, 2011, the Obama Administration released a report to Congress which included options, among others, to gradually shrink and eventually shut down Fannie Mae and Freddie Mac. We do not know when or if Fannie Mae or Freddie Mac will restrict their support of lending to the multifamily industry or to us in particular. As of March 31, 2014, 18% of our outstanding debt was borrowed through credit facilities provided by or credit-enhanced by Fannie Mae or Freddie Mac with agency rate-based maturities ranging from 2014 through 2018. We decreased the indebtedness outstanding on our Fannie Mae and Freddie Mac credit facilities from $727.9 million on March 31, 2013 to $633.4 million on March 31, 2014. Since March 31, 2013 we have added $799.2 million of unsecured senior notes and added an additional $400.0 million of unsecured term loans. A decision by the U.S. government to eliminate or downscale Fannie Mae or Freddie Mac or to reduce government support for multifamily housing more generally may adversely affect interest rates, capital availability, development of multifamily communities and the value of multifamily residential real estate and, as a result, may adversely affect us and our growth and operations.

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

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

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

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

Issuances of additional debt or equity may adversely impact our financial condition.

Our capital requirements depend on numerous factors, including the occupancy and turnover rates of our apartment communities, development and capital expenditures, costs of operations and potential acquisitions. We cannot accurately predict the timing and amount of our capital requirements. If our capital requirements vary materially from our plans, we may require additional financing sooner than anticipated. Accordingly, we could become more leveraged, resulting in increased risk of default on our obligations and in an increase in our debt service requirements, both of which could adversely affect our

60

financial condition and ability to access debt and equity capital markets in the future. If we issue additional equity securities to obtain additional financing, the interest of our existing shareholders could be diluted.

Risks Related to MAA's Organization and Ownership of Its Stock

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

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

• will consider the transfer to be null and void;

• will not reflect the transaction on its books;

• may institute legal action to enjoin the transaction;

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

• will not recognize any voting rights for those shares;

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

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

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

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

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

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

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

If you acquire shares in violation of the limits on ownership described above:

• you may lose your power to dispose of the shares;

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

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

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

Ownership Limit

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

Preferred Stock

MAA's charter authorizes our Board of Directors to issue up to 20,000,000 shares of preferred stock. The Board of Directors may establish the preferences and rights of any preferred shares issued. The issuance of preferred stock could have the effect of delaying or preventing someone from taking control of MAA, even if a change in control were in MAA shareholders’ best interests. As of March 31, 2014, no shares of preferred stock were issued and outstanding.

61

Tennessee Anti-Takeover Statutes

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

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

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

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

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

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

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

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

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

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

• additions and departures of key personnel;

• inability to access the capital markets;

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

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

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

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

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

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

• speculation in the press or investment community;

• actions by institutional shareholders or hedge funds;

• changes in accounting principles;

• terrorist acts; and

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

62

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

Risks Related to the Operating Partnership's Organization and Ownership of OP Units

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

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

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

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

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

MAA, as the Operating Partnership's sole general partner and acting through its officers and directors, has a substantial influence on the Operating Partnership's affairs. MAA, its officers and directors could exercise their influence in a manner that is not in the best interest of the Operating Partnership's unitholders. Also, MAA owns approximately 94.7% of the OP Units and as such, will have substantial influence on the outcome of any matters submitted to the Operating Partnership's unitholders for approval.

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

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

Changes in market conditions or a failure to meet the market’s expectations with regard to MAA's results of operations and cash distributions could adversely affect the market price of MAA's common stock, which may reduce the amount of cash available to the Operating Partnership to meet its obligations.

As discussed above under “Risks Related to MAA’s Organization and Ownership of its Stock,” changes in market conditions or a failure to meet the market’s expectations with regard to MAA’s results of operations and cash distributions could adversely affect the market price of MAA’s common stock. In addition, the Operating Partnership is subject to the risk that its cash flow will be insufficient to service its debt and to pay distributions to its unitholders, which may cause MAA to not have the funds to service its debt or to pay dividends to its shareholders. MAA’s failure to meet the market’s expectations with regard to future results of operations and cash distributions would likely adversely affect the market price of its shares and thus

63

potentially reduce MAA’s ability to contribute funds from issuances down to the Operating Partnership, resulting in a lower level of cash available for investment or to service our debt or to make distributions to the Operating Partnership’s unitholders.

Risks Related to Tax Laws

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

If MAA fails to qualify as a REIT for federal income tax purposes, it will be subject to federal income tax on its taxable income at regular corporate rates (subject to any applicable alternative minimum tax). In addition, unless MAA is entitled to relief under applicable statutory provisions, it would be ineligible to make an election for treatment as a REIT for the four taxable years following the year in which MAA loses its qualification. The additional tax liability resulting from the failure to qualify as a REIT would significantly reduce or eliminate the amount of funds available for distribution to MAA’s shareholders. Furthermore, MAA would no longer be required to make distributions to its shareholders. Thus, MAA’s failure to qualify as a REIT could also impair its ability to expand its business and raise capital, and would adversely affect the value of its common stock.

MAA believes that it is organized and qualified as a REIT, and MAA intends to operate in a manner that will allow it to continue to qualify as a REIT. However, MAA cannot assure you that it is qualified as a REIT, or that MAA will remain qualified in the future. This is because qualification as a REIT involves the application of highly technical and complex provisions of the Code for which there are only limited judicial and administrative interpretations and involves the determination of a variety of factual matters and circumstances not entirely within MAA’s control. In addition, future legislation, new regulations, administrative interpretations or court decisions may significantly change the tax laws or the application of the tax laws with respect to qualification as a REIT for federal income tax purposes or the federal income tax consequences of this qualification.

Even if MAA qualifies as a REIT, we will be subject to certain federal, state and local taxes on our income and property and on taxable income that MAA does not distribute to its shareholders. In addition, MAA may hold certain assets and engage in certain activities that a REIT could not engage in directly through its taxable REIT subsidiaries, or TRSs, and will be subject to federal income tax at regular corporate rates on the income of those subsidiaries.

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

We believe that the Operating Partnership qualifies, and has so qualified since its formation, as a partnership for federal income tax purposes and not as a publicly traded partnership taxable as a corporation. No assurance can be provided, however, that the Internal Revenue Service, or IRS will not challenge the treatment of the Operating Partnership as a partnership for federal income tax purposes or that a court would not sustain such a challenge. If the IRS were successful in treating the Operating Partnership as a corporation for federal income tax purposes, then the taxable income of the Operating Partnership would be taxable at regular corporate income tax rates. In addition, the treatment of the Operating Partnership as a corporation would cause MAA to fail to qualify as a REIT. See “Failure to qualify as a REIT would cause us to be taxed as a corporation, which would significantly reduce funds available for distribution to shareholders” above.

CHANGE IN CONTROL AND TERMINATION AGREEMENT

RECITALS:

WHEREAS, the Company acknowledges that the Employee’s contributions to the past and future growth and success of the Company have been and will continue to be substantial. As a publicly held corporation, the Company recognizes that there exists a possibility of a Change in Control (as defined herein) of the Company. The Company also recognizes that the possibility of such a Change in Control may contribute to uncertainty on the part of management and may result in the departure or distraction of senior management from their operating responsibilities.

WHEREAS, outstanding management of the Company is always essential to advancing the best interests of the Company’s shareholders. In the event of a threat or occurrence of a bid to acquire or change control of the Company or to effect a business combination, it is particularly important that the Company’s businesses be continued with a minimum of disruption. The Company believes that the objective of securing and retaining outstanding management will be achieved if the Company’s key management employees are given assurances of employment security so they will not be distracted by personal uncertainties and risks created by such circumstances.

For purposes of this subsection, no act, or failure to act, shall be deemed “willful” unless done, or omitted to be done, by the Employee not in good faith, and without reasonable belief that such action or omission was in the best interest of the Company.

“Termination Without Cause” means the termination of the Employee’s employment by the Company for any reason other than Termination With Cause, or termination by the Company due to the Employee’s death or Permanent Disability.

“Threshold Amount” means three times the Employee’s “base amount” within the meaning of Section 280G(b)(3) of the Code.

Employee so ceases to carry out his duties. Voluntary refusal to perform services shall not include taking accrued and unused vacation, the Employee’s failure to perform services on account of his illness or the illness of a member of his immediate family, provided such illness is adequately substantiated at the reasonable request of the Company, or any other absence from service with the written consent of the Board.

Notwithstanding any other provision in this Agreement or any other agreement pre-dating this Agreement between the Company and the Employee, in the event of a Change in Control Termination, the Company shall, on the Termination Date in respect of such Change in Control Termination, pay the Employee, in addition to any Base Salary earned but not paid through the Termination Date and any amounts due pursuant to Award Plans and Benefit Plans including, without limitation, the pro rata amount of the Employee’s anticipated bonus for the fiscal year in which the Employee’s employment is so terminated, the compensation and benefits set forth in Section 3(b).

(b)Compensation and Benefits.

(i)A Termination Payment shall be paid which is equal to the sum of _____ times the Employee’s annual base salary in effect on the Termination Date plus _____ times the average annual cash bonus paid to the Employee for the two immediately preceding fiscal years, under this Agreement or otherwise (“Termination Payment”). Notwithstanding Section 3(a), the Termination Payment shall be calculated and paid immediately prior to the closing of the transactions constituting a Change in Control if the Employee receives notice prior to the Change in Control that his employment will be terminated on or after the Change in Control.

(ii)The Employee acknowledges that pursuant to the terms of the Benefit Plans, he is not eligible to continue to participate in the Benefit Plans as a former employee, except as a participant in the medical, dental, and vision plans for which the Employee was enrolled in at the time of Termination as provided by the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), or by state-law continuation of coverage rules. If the Employee is entitled to COBRA or state-law continuation coverage, then the Company shall provide the Employee with a lump sum payment equal to [__] months of the Company’s monthly contribution to the medical, dental, and vision plans in which the Employee was enrolled in immediately prior to the Termination Date. The Company’s monthly contribution shall be determined by averaging the Employer’s monthly contribution over the twelve (12) month period immediately preceding Termination.

(iii)The Company shall also pay to the Employee all legal fees and expenses incurred by the Employee as a result of a termination described in Section 3(a) of this Agreement (including all such fees and expenses, if any, incurred in contesting or disputing any such termination or in seeking to obtain or enforce any right or benefit provided by this Agreement.

(c)Additional Limitation.

(i)Anything in this Agreement to the contrary notwithstanding, in the event that the Employee’s Change in Control Benefits, calculated in a manner consistent with Section 280G of the Code and the applicable regulations thereunder, would be subject to the excise tax imposed by Section 4999 of the Code, the following provisions shall apply:

(1)If the Change in Control Benefits, reduced by the sum of (A) the Excise Tax and (B) the total of the federal, state, and local income and employment taxes payable by the Employee on the amount of the Change in Control Benefits which are in excess of the Threshold Amount, are greater than or equal to the Threshold Amount, the Employee shall be entitled to the full amount of Change in Control Benefits.

(2)If the Threshold Amount is less than (x) the Change in Control Benefits, but greater than (y) the Change in Control Benefits reduced by the sum of (A) the Excise Tax and (B) the total of the federal, state, and local income and employment taxes on the amount of the Change in Control Benefits which are in excess of the Threshold Amount, then the Change in Control Benefits shall be reduced (but not below zero) to the extent necessary so that the sum of all Severance Payments shall not exceed the Threshold Amount. In such event, the Change in Control Benefits shall be reduced in the following order: (i) cash payments not subject to Section 409A of the Code; (ii) cash payments subject to Section 409A of the Code; (iii) equity-based payments and acceleration; and (iv) non-cash forms of benefits. To the extent any payment is to be made over time (e.g., in installments, etc.), then the payments shall be reduced in reverse chronological order.

(ii)The determination as to which of the alternative provisions of Section 3(c) above shall apply to the Employee shall be made by a nationally recognized accounting firm selected by the Company (the “Accounting Firm”), which shall provide detailed supporting calculations both to the Company and the Employee within 15 business days of the Termination Date, if applicable, or at such earlier time as is reasonably requested by the Company or the Employee. For purposes of determining which of the alternative provisions of Section 3(c) above shall apply, the Employee shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the calendar year in which the determination is to be made, and state and local income taxes at the highest marginal rates of individual taxation in the state and locality of the Employee’s residence on the Termination Date, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes. Any determination by the Accounting Firm shall be binding upon the Company and the Employee.

4.Noncompetition. During the Term, the Employee shall not, other than through the Company or affiliates of the Company, own any interest in any Multi-Family Residential Property (other than Multi-Family Residential Property in which the Company or the Partnership has an ownership interest), as partner, shareholder or otherwise, or engage in the Multi-Family Residential Business, directly or indirectly, for his own account or for the account of others, either as an officer, director, shareholder, owner, partner, promoter, employee, consultant, advisor, agent, manager, or in any other capacity. For a period of one year after a Change in Control Termination, the Employee shall not own any interest in any Multi-Family Residential Property as partner, shareholder or otherwise, or directly or indirectly, for his own account or for the account of others, either as an officer, director, promoter, employee, consultant, advisor, agent, manager, or in any other capacity, engage in the Multi-Family Residential Business within 35 miles of any Multi-Family Residential Property owned by the Company or the Partnership at the time of termination of employment.

The Employee agrees that damages at law for violation of the restrictive covenant contained herein would not be an adequate or proper remedy to the Company, and that should the Employee violate or threaten

to violate any of the provisions of such covenant, the Company, its successors or assigns, shall be entitled to obtain a temporary or permanent injunction, as appropriate, against the Employee in any court having jurisdiction over the person and the subject matter, prohibiting any further violation of any such covenants. The Parties agree to personal jurisdiction in the courts located in Shelby County, Tennessee, and agree that venue is appropriate in said County. The injunctive relief provided herein shall be in addition to any award of damages, compensatory, exemplary or otherwise, payable by reason of such violation. The Employee agrees that the Company will be entitled to recover attorney fees and costs incurred as a result of the Employee’s breach of this Agreement.

Furthermore, the Employee acknowledges that this Agreement had been negotiated at arms’ length by the parties, neither being under any compulsion to enter into this Agreement, and that the foregoing restrictive covenant does not in any respect inhibit his ability to earn a livelihood in his chosen profession without violating the restrictive covenant contained herein. The Company by these presents has attempted to limit the Employee’s right to compete only to the extent necessary to protect the Company from unfair competition. The Company recognizes, however, that reasonable people may differ in making such a determination. Consequently, the Company agrees that if the scope or enforceability of the restricted covenant contained herein is in any way disputed at any time, a court or other trier of fact may modify and enforce the covenant to the extent that it believes to be reasonable under the circumstances existing at the time.

5.Employment Status. The parties acknowledge that the Employee is an “at will” employee of the Company and has not contractual right to continued employment or compensation in the event of termination of the Employee’s employment for any reason or no reason at all, other than as set forth in this Agreement. The parties acknowledge and agree that the Employee is not an independent contractor. Any payments made to the Employee by the Company pursuant to this Agreement shall be treated for federal and state payroll tax purposes as payments made to a Company employee, irrespective of whether such payments are made subsequent to the Termination Date.

6.Notices. All notices or deliveries authorized or required pursuant to this Agreement shall be deemed to have been given when in writing and personally delivered or when deposited in the U.S. mail, certified, return receipt requested, postage prepaid, addressed to the parties at the following addresses or to such other addresses as either may designate in writing to the other party:

7.Entire Agreement. This Agreement contains the entire understanding between the parties hereto with respect to the subject matter hereof and shall not be modified in any manner except by instrument in writing signed, by or on behalf of, the parties hereto; provided, however, that any amendment or termination of the covenant of noncompetition in Section 4 must be approved by a majority of the Directors of the Company other than the Employee, if the Employee is then a director of the Company. This Agreement shall be binding upon and inure to the benefit of the heirs, successors and assigns of the parties hereto.

8.Arbitration. Except for requests for injunctive relief and for damages under Section 4, Noncompetition, any controversy concerning or claim arising out of or relating to this Agreement shall be

settled by final and binding arbitration in Memphis, Shelby County, Tennessee at a location specified by the party seeking such arbitration.

(a)The Arbitrators. Any arbitration proceeding shall be conducted by three (3) Arbitrators and the decision of the Arbitrators shall be binding on all parties. Each Arbitrator shall have substantial experience and expert competence in the matters being arbitrated. The part desiring to submit any matter relating to this Agreement to arbitration shall do so by written notice to the other party, which notice shall set forth the items to be arbitrated, such party’s choice of Arbitrator, and such party’s substantive position in the arbitration. The party receiving such notice shall, within fifteen (15) days after receipt of such notice, appoint an Arbitrator and notify the other party of its appointment and of its substantive position. The Arbitrators appointed by the parties to the Arbitration shall select an additional Arbitrator meeting the aforedescribed criteria. The Arbitrators shall be required to render a decision in accordance with the procedures set forth in Subparagraph (b) below within thirty (30) days after being notified of their selection. The fees of the Arbitrators shall be equally divided amongst the parties to the arbitration.

(b)Arbitration Procedures. Arbitration shall be conducted in accordance with the Uniform Arbitration Act, except to the extent the provisions of such Act are modified by this Agreement or the subsequent mutual agreement of the parties. Judgment upon the award rendered by the Arbitrator(s) may be entered in any court having jurisdiction thereof. Any party hereto may bring an action, including a summary or expedited proceeding, to compel arbitration of any controversy or claim to which this provision applies in any court having jurisdiction over such action in Shelby County, Tennessee, and the parties agree that jurisdiction and venue in Shelby County, Tennessee are appropriate and approved by such parties.

9.Applicable Law. This Agreement shall be governed and construed in accordance with the laws of the State of Tennessee.

10.Assignment. The Employee acknowledges that his services are unique and personal. Accordingly, the Employee may not assign his rights or delegate his duties or obligations under this Agreement, except with respect to certain rights to receive payments as described in Section 7.

11.Headings. Headings in this Agreement are for convenience only and shall not be used to interpret or construe is provisions.

12.Successors; Binding Agreement. The Company will require any successor to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Failure of the Company to obtain such assumption and agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle the Employee to compensation from the Company in the same amount and on the same terms as the Employee would be entitled to hereunder if the Employee terminates his employment for Good Reason. The Company’s rights and obligations under this Agreement shall inure to the benefit of and shall be binding upon the Company’s successors and assigns.

13.Section 409A.

(a)Anything in this Agreement to the contrary notwithstanding, if at the time of the Employee’s “separation from service” within the meaning of Section 409A of the Code, the Company determines that the Employee is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that the Employee becomes entitled to under this Agreement on account of the Employee’s separation from service would be considered deferred compensation subject to the 20

percent additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such benefit shall not be provided until the date that is the earlier of (A) six months and one day after the Employee’s separation from service, or (B) the Employee’s death.

(b)The parties intend that this Agreement will be administered in accordance with Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with Section 409A of the Code. The parties agree that this Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party.

(c)All in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be provided by the Company or incurred by the Employee during the time periods set forth in this Agreement. All reimbursements shall be paid as soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the expense was incurred. The amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for reimbursement in any other taxable year. Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit.

(d)To the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the Employee’s termination of employment, then such payments or benefits shall be payable only upon the Employee’s “separation from service.” The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A-1(h).

(e)The Company makes no representation or warranty and shall have no liability to the Employee or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.

IN WITNESS WHEREOF, the parties have executed this Agreement effective as of the date first above written.

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 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 95% to 100% of all consolidated subsidiaries. The consolidated financial statements of MAALP presented herein include the accounts of MAALP and all other subsidiaries in which MAALP has a controlling financial interest. MAALP owns, directly or indirectly, 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 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. 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. These entities are not variable interest entities. 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.

Merger of MAA and Colonial

On October 1, 2013, we completed our merger with Colonial. Pursuant to the merger agreement, Martha Merger Sub, LP, or OP Merger Sub, a wholly-owned indirect subsidiary of our Operating Partnership, merged with and into Colonial LP, with Colonial LP being the surviving entity of the merger and becoming a wholly-owned indirect subsidiary of our Operating Partnership, which is referred to as the partnership merger. The partnership merger was part of the transactions contemplated by the agreement and plan of merger entered into on June 3, 2013 among MAA, our Operating Partnership, OP Merger Sub, Colonial, and Colonial LP pursuant to which MAA and Colonial combined through a merger of Colonial with and into MAA, with MAA surviving the merger, which is referred to as the parent merger. Under the terms of the merger agreement, each Colonial common share was converted into the right to receive 0.36 of a newly issued share of MAA common stock. In addition, each limited partner interest in Colonial LP designated as a “Class A Unit” and a “Partnership Unit” under the limited partnership agreement of Colonial LP, which we refer to in this filing as Colonial LP units, issued and outstanding immediately prior to the effectiveness of the partnership merger was converted into common units in our Operating Partnership at the 0.36 conversion rate.

As part of the merger, we acquired 115 wholly owned apartment communities encompassing 34,370 units principally located in the Southeast and Southwest regions of the United States. In addition to the apartment communities, we also acquired four commercial properties totaling approximately 806,000 square feet. The additions have caused us to nearly double in size as a result of the merger. The net assets and results of operations of Colonial are included in our consolidated financial statements from the closing date, October 1, 2013, going forward.

The total purchase price of approximately $2.2 billion was determined based on the number of Colonial shares of common stock and Colonial OP Units outstanding, as of October 1, 2013. In all cases in which MAA’s 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 October 1, 2013 ($62.56 per share). The total purchase price includes $7.3 million of other consideration, a majority of which relates to assumed stock compensation plans. As a result of the Merger, we issued approximately 31.9 million shares of MAA common stock and approximately 2.6 million OP units.

The acquisition 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 NOI and a 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. The following purchase price allocation was based on our valuation, estimates and assumptions of the acquisition date fair value of the tangible and intangible assets acquired and liabilities assumed. While the current allocation of the purchase price is substantially complete, the valuation of the real estate properties and certain other assets and liabilities is in the process of being finalized. We do not expect future revisions, if any, to have a significant impact on our financial position or results of operations.

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

Land	$	469,396
Buildings and improvements	3,075,642
Furniture, fixtures and equipment	96,377
Development and capital improvements in progress	113,368

Accounts payable, accrued expenses, and other liabilities	(125,034)
Total liabilities assumed, including debt	(1,899,545		)
Total purchase price	$	2,162,876

We incurred merger and integration related expenses of $5.9 million for the three months ended March 31, 2014. These amounts were expensed as incurred and are included in the Consolidated Statement of Operations in the items titled Merger related expenses and Integration related expenses.

The allocation of fair values of the assets acquired and liabilities assumed has changed from the allocation reported in Item 8. Financial Statements and Supplementary Data - Notes to Consolidated Financial Statements, Note 2 of our Annual Report on Form 10-K for the year ended December 31, 2013, filed with the SEC on February 21, 2014. The changes were based on information concerning the subject assets and liabilities that was not yet available at the time of the 10-K filing. These adjustments had no material impact on the results of operations.

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

Consolidation and Basis of Presentation and Significant Accounting Policies

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

As of March 31, 2014, MAA owned 75,009,303 units (or approximately 94.7%) of the limited partnership interests of the Operating Partnership. 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 notes to the consolidated financial statements 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.

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 limited 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 partnership units.

The presentation of MAA's shareholders' equity and the Operating Partnership's capital are the principal areas of difference between the consolidated financial statements of MAA and those of the Operating Partnership. MAA's shareholders' equity may include shares of preferred stock, shares of common stock, additional paid-in capital, cumulative earnings, cumulative distributions, noncontrolling interest, 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 interest, accumulated other comprehensive income and redeemable common units. Redeemable common units represent the number of outstanding OP Units as of the date of the applicable balance sheet, valued for conversion at the greater of the closing market price of MAA's common stock or the aggregate value of the individual partners' capital balances. Each redeemable OP Unit may be redeemed by the holder thereof for either cash equal to the fair market value of one share of common stock of MAA at the time of such redemption or, at the option of MAA, one share of common stock of MAA.

Organization and Formation of Mid-America Apartment Communities, Inc.

On October 1, 2013, MAA acquired Colonial Properties Trust, or Colonial, when Colonial was merged with and into MAA, with MAA being the surviving entity of the merger, pursuant to an agreement and plan of merger, which is referred to as the parent merger and Martha Merger Sub, LP, or OP Merger Sub, a wholly-owned indirect subsidiary of MAALP, merged with and into Colonial Realty Limited Partnership, or Colonial LP, with Colonial LP being the surviving entity of the merger and becoming a wholly-owned indirect subsidiary of MAALP, which is referred to as the partnership merger. Under the terms of the merger agreement, each Colonial common share was converted into the right to receive 0.36 of a newly issued share of MAA common stock. In addition, each limited partner interest in Colonial LP designated as a “Class A Unit” and a “Partnership Unit” under the limited partnership agreement of Colonial LP, which we refer to in this filing as Colonial LP units, issued and outstanding immediately prior to the effectiveness of the partnership merger was converted into common units in MAALP at the 0.36 conversion rate. The net assets and results of operations of Colonial are included in our consolidated financial statements from the closing date, October 1, 2013 going forward.

As of March 31, 2014, we owned and operated 269 apartment communities comprising 82,730 apartments located in 14 states principally through the Operating Partnership and we also owned an interest in the following unconsolidated real estate joint ventures:

	Percent Owned	Number of Units/Square Feet
Multifamily:
Mid-America Multifamily Fund II, LLC (Fund II)	33.33%	594	(1)
Belterra	10.00%	288	(2)
McKinney	25.00%	—	(3)
Commercial:
Land Title Building	33.30%	29,971

⁽¹⁾ This joint venture is comprised of two apartment communities.

⁽²⁾ This joint venture is not managed by MAA and is not included in our property totals.

⁽³⁾ This joint venture consists of undeveloped land.

As of March 31, 2014, we had four development communities under construction totaling 999 units, with 305 units completed. Total expected costs for the development projects are $146.0 million, of which $98.7 million has been incurred to date. We expect to complete construction on all four projects by the first quarter of 2015. Four of our multifamily properties include retail components with approximately 100,000 square feet of gross leasable area. We also have three wholly owned commercial properties, which we acquired through our merger with Colonial with approximately 287,000 square feet of gross leasable area, excluding tenant owned anchor stores, and one partially owned commercial property with approximately 30,000 square feet of 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 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 95% to 100% of all consolidated subsidiaries. The consolidated financial statements of MAALP presented herein include the accounts of MAALP and all other subsidiaries in which MAALP has a controlling financial interest. MAALP owns, directly or indirectly, 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 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. 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. These entities are not variable interest entities. 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.

Shareholders' Equity of MAA

On March 31, 2014, 75,009,303 shares of common stock of MAA and 4,208,526 partnership units in the Operating Partnership were issued and outstanding, representing a total of 79,217,829 shares and units. At March 31, 2013, 42,683,322 shares of common stock of MAA and 1,707,660 partnership units in the Operating Partnership were outstanding, representing a total of 44,390,982 shares and units. There were 296,583 outstanding options as of March 31, 2014 compared to zero outstanding options as of March 31, 2013. The primary reason for the increase in shares and units is due to the merger with Colonial. In connection with the merger, on October 1, 2013, we issued 31,916,765 shares and 2,574,631 partnership units.

On August 26, 2010, we and our Operating Partnership entered into sales agreements with Cantor Fitzgerald & Co., Raymond James & Associates, Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated to sell up to a combined total of 6,000,000 shares of our common stock, from time to time in at-the-market offerings or negotiated transactions through a controlled equity offering program, or ATM. We terminated this ATM program, and on February 25, 2013, we and our Operating Partnership entered into sales agreements with J.P. Morgan Securities LLC, BMO Capital Markets Corp., KeyBanc Capital Markets Inc. and UBS Securities LLC to sell up to 4,500,000 shares of our common stock with materially the same terms as our previous sales agreements.

During the three-month period ended March 31, 2014, we issued no shares through our ATM programs. During the three-month period ended March 31, 2013, we issued 325,166 shares through our ATM programs for net proceeds of $22.0 million. The gross proceeds for these issuances were $22.3 million. We have 4,134,989 shares remaining under our ATM program as of March 31, 2014.

During the three-month period ended March 31, 2014, we issued 340 shares of common stock through the optional cash purchase feature of our Dividend and Distribution Reinvestment and Share Purchase Program, or DRSPP. The issuances resulted in gross proceeds of approximately $23,000. During the three-month period ended March 31, 2013, we issued 141 shares of common stock through the optional cash purchase feature of our DRSPP resulting in gross proceeds of approximately $10,000.

During the three months ended March 31, 2014, 6,554 shares of our 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 three months ended March 31, 2013, 4,582 shares were acquired for these purposes.

Partners' Capital of Mid-America Apartments, L.P.

Interests in MAALP are represented by OP Units. As of March 31, 2014, there were 79,217,829 OP Units outstanding, 75,009,303 or 94.7% of which were owned by MAA, MAALP's general partner. The remaining 4,208,526 OP Units were owned by non-affiliated limited partners ("Class A Limited Partners"). As of March 31, 2013, there were 44,390,982 OP Units outstanding, 42,683,322 or 96.2% of which were owned by MAA and 1,707,660 of which were owned by the Class A Limited Partners. The increase in OP Units was due primarily to the merger with Colonial Properties Trust. In order to complete the merger, on October 1, 2013, we issued 34,491,396 OP Units.

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

Under the Partnership Agreement, the Operating Partnership may issue Class A OP Units and Class B OP Units. Class A OP 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 OP Units may only be held by MAA, in its capacity as general partner of the Operating Partnership, and as of March 31, 2014, a total of 4,208,526 Class A OP Units in the Operating Partnership were held by limited partners unaffiliated with MAA, while a total of 75,009,303 Class B OP 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 OP Units is also limited by the Partnership Agreement.

Net income 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 OP Units or Class B OP Units changes the relative ownership percentage of the partners. The issuance of Class B OP Units generally occurs when MAA issues common stock and the proceeds from that issuance are contributed to 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 OP Units with similar terms held by MAA for a redemption price equal to the purchase price of those shares of common stock. At each reporting period, the allocation between general partner capital and limited partner capital is adjusted to account for the change in the respective percentage ownership of the underlying capital of the Operating Partnership. Holders of the Class A OP Units may require MAA to redeem their Class A OP Units, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per Class A OP Unit equal, in general, to the average closing price of MAA's common stock on the New York Stock Exchange over a specified period prior to the redemption date) or by delivering one share of MAA common stock (subject to adjustment under specified circumstances) for each Class A OP Unit so redeemed.

At March 31, 2014, a total of 4,208,526 Class A OP Units were outstanding and redeemable for 4,208,526 shares of MAA common stock or approximately $287,316,070, based on the closing price of MAA’s common stock on March 31, 2014 of $68.27 per share, at MAA’s option. At March 31, 2013, a total of 1,707,660 Class A OP Units were outstanding and redeemable for 1,707,660 shares of MAA common stock or approximately $117,931,000, based on the closing price of MAA’s common stock on March 31, 2013 of $69.06 per share, at MAA’s option.

The Operating Partnership pays the same per unit distribution in respect to the OP Units as the per share dividend MAA pays in respect to its common and preferred stock.

Shareholders' Equity of MAA

On March 31, 2014, 75,009,303 shares of common stock of MAA and 4,208,526 partnership units in the Operating Partnership were issued and outstanding, representing a total of 79,217,829 shares and units. At March 31, 2013, 42,683,322 shares of common stock of MAA and 1,707,660 partnership units in the Operating Partnership were outstanding, representing a total of 44,390,982 shares and units. There were 296,583 outstanding options as of March 31, 2014 compared to zero outstanding options as of March 31, 2013. The primary reason for the increase in shares and units is due to the merger with Colonial. In connection with the merger, on October 1, 2013, we issued 31,916,765 shares and 2,574,631 partnership units.

On August 26, 2010, we and our Operating Partnership entered into sales agreements with Cantor Fitzgerald & Co., Raymond James & Associates, Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated to sell up to a combined total of 6,000,000 shares of our common stock, from time to time in at-the-market offerings or negotiated transactions through a controlled equity offering program, or ATM. We terminated this ATM program, and on February 25, 2013, we and our Operating Partnership entered into sales agreements with J.P. Morgan Securities LLC, BMO Capital Markets Corp., KeyBanc Capital Markets Inc. and UBS Securities LLC to sell up to 4,500,000 shares of our common stock with materially the same terms as our previous sales agreements.

During the three-month period ended March 31, 2014, we issued no shares through our ATM programs. During the three-month period ended March 31, 2013, we issued 325,166 shares through our ATM programs for net proceeds of $22.0 million. The gross proceeds for these issuances were $22.3 million. We have 4,134,989 shares remaining under our ATM program as of March 31, 2014.

During the three-month period ended March 31, 2014, we issued 340 shares of common stock through the optional cash purchase feature of our Dividend and Distribution Reinvestment and Share Purchase Program, or DRSPP. The issuances resulted in gross proceeds of approximately $23,000. During the three-month period ended March 31, 2013, we issued 141 shares of common stock through the optional cash purchase feature of our DRSPP resulting in gross proceeds of approximately $10,000.

During the three months ended March 31, 2014, 6,554 shares of our 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 three months ended March 31, 2013, 4,582 shares were acquired for these purposes.

Partners' Capital of Mid-America Apartments, L.P.

Interests in MAALP are represented by OP Units. As of March 31, 2014, there were 79,217,829 OP Units outstanding, 75,009,303 or 94.7% of which were owned by MAA, MAALP's general partner. The remaining 4,208,526 OP Units were owned by non-affiliated limited partners ("Class A Limited Partners"). As of March 31, 2013, there were 44,390,982 OP Units outstanding, 42,683,322 or 96.2% of which were owned by MAA and 1,707,660 of which were owned by the Class A Limited Partners. The increase in OP Units was due primarily to the merger with Colonial Properties Trust. In order to complete the merger, on October 1, 2013, we issued 34,491,396 OP Units.

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

Under the Partnership Agreement, the Operating Partnership may issue Class A OP Units and Class B OP Units. Class A OP 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 OP Units may only be held by MAA, in its capacity as general partner of the Operating Partnership, and as of March 31, 2014, a total of 4,208,526 Class A OP Units in the Operating Partnership were held by limited partners unaffiliated with MAA, while a total of 75,009,303 Class B OP 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 OP Units is also limited by the Partnership Agreement.

Net income 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 OP Units or Class B OP Units changes the relative ownership percentage of the partners. The issuance of Class B OP Units generally occurs when MAA issues common stock and the proceeds from that issuance are contributed to 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 OP Units with similar terms held by MAA for a redemption price equal to the purchase price of those shares of common stock. At each reporting period, the allocation between general partner capital and limited partner capital is adjusted to account for the change in the respective percentage ownership of the underlying capital of the Operating Partnership. Holders of the Class A OP Units may require MAA to redeem their Class A OP Units, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per Class A OP Unit equal, in general, to the average closing price of MAA's common stock on the New York Stock Exchange over a specified period prior to the redemption date) or by delivering one share of MAA common stock (subject to adjustment under specified circumstances) for each Class A OP Unit so redeemed.

At March 31, 2014, a total of 4,208,526 Class A OP Units were outstanding and redeemable for 4,208,526 shares of MAA common stock or approximately $287,316,070, based on the closing price of MAA’s common stock on March 31, 2014 of $68.27 per share, at MAA’s option. At March 31, 2013, a total of 1,707,660 Class A OP Units were outstanding and redeemable for 1,707,660 shares of MAA common stock or approximately $117,931,000, based on the closing price of MAA’s common stock on March 31, 2013 of $69.06 per share, at MAA’s option.

The Operating Partnership pays the same per unit distribution in respect to the OP Units as the per share dividend MAA pays in respect to its common and preferred stock.

Earnings Per OP Unit of MAALP [Abstract]

Earnings Per Share [Text Block]

Earnings per Common Share of MAA

Basic earnings per share is computed by dividing net income attributable to 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.  Operating partnership units are included in dilutive earnings per share calculations when they are dilutive to earnings per share. For the three months ended March 31, 2014 and 2013, MAA's basic earnings per share is computed using the two-class method, and our diluted earnings per share is computed using the more dilutive of the treasury stock method or two-class method:

⁽¹⁾ Operating partnership units, other dilutive securities, and the related income with each are not included in the diluted earnings per share calculations as they were not dilutive.

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 units outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends 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 unit computations for the three months ended March 31, 2014 and 2013 is presented below:

Impact of Recently Issued Accounting Standards

In April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 raises the threshold for disposals to qualify as discontinued operations. It also requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. The ASU is effective for fiscal years beginning after December 15, 2014, and interim periods within those years; however, early adoption is permitted beginning in the first quarter of 2014. We adopted ASU 2014-08 during the period ending March 31, 2014. The adoption of ASU 2014-08 required us to not classify certain disposals occurring during the first quarter of 2014 as discontinued operations.

In January 2013, the FASB issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. ASU 2013-01 clarifies that the scope of ASU 2011-11, Disclosures about Offsetting Assets and Liabilities, would apply to derivatives accounted for in accordance with FASB ASC 815, Derivatives and Hedging, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with ASC 210-20-45 or ASC 815-10-45 or subject to an enforceable master netting arrangement or similar agreement. This ASU is effective for fiscal years beginning on or after January 1, 2013 and interim periods within those annual periods. We adopted ASU 2013-01 during the period ended March 31, 2013. The adoption of ASU 2013-01 has not had a material impact on our consolidated financial condition or results of operations taken as a whole.

Legal Proceedings [Abstract]

Legal Matters and Contingencies [Text Block]

Legal Proceedings

The Company (by virtue of its merger with Colonial) and Colonial LP along with multiple other parties, are named defendants in lawsuits arising out of alleged construction deficiencies with respect to condominium units at Regatta at James Island in Charleston, South Carolina. Regatta at James Island property was developed by certain of the Company's subsidiaries and constructed by Colonial Construction Services, LLC. The condominiums were constructed in 2006 and all 212 units were sold. The lawsuits, one filed on behalf of the condominium homeowners association and one filed by three of the unit owners (purportedly on behalf of all unit owners), were filed in South Carolina state court (Charleston County) in August 2012, against various parties involved in the development and construction of the Regatta at James Island property, including the contractors, subcontractors, architect, developer, and product manufacturers. The plaintiffs are seeking damages resulting primarily from alleged construction deficiencies, but the amount plaintiffs seek to recover has not been disclosed. The lawsuits are currently in discovery. The Company is continuing to investigate the matter and evaluate its options and intends to vigorously defend itself against these claims. No assurance can be given that the matter will be resolved favorably to the Company. The Companyhas included in its loss contingency an estimate of probable loss in connection with this matter, but currently cannot reasonably estimate any further possible loss, or any range of reasonably possible loss, in connection with this matter.

The Company (by virtue of its merger with Colonial) and Colonial LP along with multiple other parties, are named defendants in a lawsuit arising out of alleged construction deficiencies with respect to condominium units at Plantation Point in Bluffton, South Carolina. Plantation Point was previously owned and operated by Colonial LP as a multi-family rental project by the name of the Ashley Plantation apartments. Colonial LP sold the property in 2005 to a third party, which then converted the property to condominiums and sold all 414 units. The lawsuit, filed on behalf of the condominium homeowners association and a class of unit owners, was filed in South Carolina state court (Beaufort County) in September 2011, against various parties involved in the development, construction and conversion of the Plantation Point property, including the contractors, subcontractors, architect, developer, and product manufacturers. The plaintiffs are seeking $24.7 million in damages resulting from, among other things, alleged construction deficiencies and misleading sales practices attributed to the third-party seller. The lawsuit is currently in discovery. The Company is continuing to investigate the matter and evaluate its options and intends to vigorously defend itself against these claims. No assurance can be given that the matter will be resolved favorably to the Company. The Company has included in its loss contingency an estimate of probable loss in connection with this matter, but currently cannot reasonably estimate any further possible loss, or any range of reasonably possible loss, in connection with this matter.

On June 19, 2013, a putative class action was filed in the Circuit Court for Jefferson County, Alabama captioned Williams v. Colonial Properties Trust, et al., No. 01-CV-2013-902416.00 (the “Williams Litigation”), seeking, among other things, to enjoin the previously announced combination of MAA and Colonial in accordance with the terms of the Agreement and Plan of Merger, dated June 3, 2013, by and among MAA, the Operating Partnership, Martha Merger Sub, LP, Colonial and Colonial LP. On March 6, 2014 the Court approved the final settlement of the Williams litigation and the Company made the Court-approved immaterial payment to the Plaintiff's attorneys.

In addition, the Company is subject to various other legal proceedings and claims that arise in the ordinary course of its business operations. Matters which arise out of allegations of bodily injury, property damage, and employment practices are generally covered by insurance. While the resolution of these other matters cannot be predicted with certainty, management currently believes the final outcome of such matters will not have a material adverse effect on the financial position, results of operations or cash flows of the Company.

Loss Contingencies

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

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

Derivatives and Hedging Activities

3 Months Ended

Mar. 31, 2014

Notes To Financial Statements [Abstract]

Derivatives and Hedging Activities

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 this objective, 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 months ended March 31, 2014 and 2013, 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. During the three months ended March 31, 2014 and 2013, we recorded ineffectiveness of $4,000 (increase to interest expense) and $4,000 (decrease to interest expense), respectively, mainly attributable to a mismatch in the underlying indices of the derivatives and the hedged interest payments made on our variable-rate debt.

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 12 months, we estimate that an additional $9.7 million 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 payments.

As of March 31, 2014, we had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk:

Interest Rate Derivative	Number of Instruments	Notional
Interest Rate Caps	7	$	180,000,000
Interest Rate Swaps (1)	14	$	717,000,000

⁽¹⁾ Excludes four forward rate swaps totaling $200 million where the debt has not yet been issued. These swaps are not included in our debt discussion in MD&A or Item 1. Financial Statements – Notes to Consolidated Financial Statements, Note 7.

Non-Designated Hedges

Derivatives not designated as hedges are not speculative and are used to manage the Company's exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements of FASB ASC 815, Derivatives and Hedging. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings and resulted in a loss of $69,000 for the three months ended March 31, 2014 and a loss of $13,000 for the three months ended March 31, 2013.

As of March 31, 2014, we had the following outstanding interest rate derivatives that were not designated as hedges:

Interest Rate Derivative	Number of Instruments	Notional
Interest rate caps	15	$	134,326,000

Credit-Risk-Related Contingent Features

As of March 31, 2014, derivatives that were in a net liability position and subject to credit-risk-related contingent features had a termination value of $19.6 million, which includes accrued interest but excludes any adjustment for nonperformance risk. These derivatives had a fair value, gross of asset positions, of $17.9 million at March 31, 2014.

Certain of our derivative contracts contain a provision where if we default on any of our indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then we could also be declared in default on our derivative obligations. As of March 31, 2014, 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 their termination value of $3.4 million.

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 March 31, 2014, we had not breached the provisions of these agreements. If we had breached theses provisions, we could have been required to settle our obligations under the agreements at the termination value of $14.9 million.

Certain of our derivative contracts are credit enhanced by either FNMA or Freddie Mac.  These derivative contracts require that our credit enhancing party maintain credit ratings above a certain level.  If our credit support providers were downgraded below Baa1 by Moody’s or BBB+ by Standard & Poor’s, or S&P, we may be required to either post 100 percent collateral or settle the obligations at their termination value of $4.7 million as of March 31, 2014.  Both FNMA and Freddie Mac are currently rated Aaa by Moody’s and AA+ by S&P, and therefore, the provisions of this agreement have not been breached, and no collateral has been posted related to these agreements as of March 31, 2014.

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 Consolidated Balance Sheet.

The table below presents a gross presentation, the effects of offsetting, and a net presentation of our derivatives as of March 31, 2014 and December 31, 2013.

Shareholders' Equity of MAA

On March 31, 2014, 75,009,303 shares of common stock of MAA and 4,208,526 partnership units in the Operating Partnership were issued and outstanding, representing a total of 79,217,829 shares and units. At March 31, 2013, 42,683,322 shares of common stock of MAA and 1,707,660 partnership units in the Operating Partnership were outstanding, representing a total of 44,390,982 shares and units. There were 296,583 outstanding options as of March 31, 2014 compared to zero outstanding options as of March 31, 2013. The primary reason for the increase in shares and units is due to the merger with Colonial. In connection with the merger, on October 1, 2013, we issued 31,916,765 shares and 2,574,631 partnership units.

On August 26, 2010, we and our Operating Partnership entered into sales agreements with Cantor Fitzgerald & Co., Raymond James & Associates, Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated to sell up to a combined total of 6,000,000 shares of our common stock, from time to time in at-the-market offerings or negotiated transactions through a controlled equity offering program, or ATM. We terminated this ATM program, and on February 25, 2013, we and our Operating Partnership entered into sales agreements with J.P. Morgan Securities LLC, BMO Capital Markets Corp., KeyBanc Capital Markets Inc. and UBS Securities LLC to sell up to 4,500,000 shares of our common stock with materially the same terms as our previous sales agreements.

During the three-month period ended March 31, 2014, we issued no shares through our ATM programs. During the three-month period ended March 31, 2013, we issued 325,166 shares through our ATM programs for net proceeds of $22.0 million. The gross proceeds for these issuances were $22.3 million. We have 4,134,989 shares remaining under our ATM program as of March 31, 2014.

During the three-month period ended March 31, 2014, we issued 340 shares of common stock through the optional cash purchase feature of our Dividend and Distribution Reinvestment and Share Purchase Program, or DRSPP. The issuances resulted in gross proceeds of approximately $23,000. During the three-month period ended March 31, 2013, we issued 141 shares of common stock through the optional cash purchase feature of our DRSPP resulting in gross proceeds of approximately $10,000.

During the three months ended March 31, 2014, 6,554 shares of our 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 three months ended March 31, 2013, 4,582 shares were acquired for these purposes.

Partners' Capital of Mid-America Apartments, L.P.

Interests in MAALP are represented by OP Units. As of March 31, 2014, there were 79,217,829 OP Units outstanding, 75,009,303 or 94.7% of which were owned by MAA, MAALP's general partner. The remaining 4,208,526 OP Units were owned by non-affiliated limited partners ("Class A Limited Partners"). As of March 31, 2013, there were 44,390,982 OP Units outstanding, 42,683,322 or 96.2% of which were owned by MAA and 1,707,660 of which were owned by the Class A Limited Partners. The increase in OP Units was due primarily to the merger with Colonial Properties Trust. In order to complete the merger, on October 1, 2013, we issued 34,491,396 OP Units.

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

Under the Partnership Agreement, the Operating Partnership may issue Class A OP Units and Class B OP Units. Class A OP 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 OP Units may only be held by MAA, in its capacity as general partner of the Operating Partnership, and as of March 31, 2014, a total of 4,208,526 Class A OP Units in the Operating Partnership were held by limited partners unaffiliated with MAA, while a total of 75,009,303 Class B OP 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 OP Units is also limited by the Partnership Agreement.

Net income 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 OP Units or Class B OP Units changes the relative ownership percentage of the partners. The issuance of Class B OP Units generally occurs when MAA issues common stock and the proceeds from that issuance are contributed to 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 OP Units with similar terms held by MAA for a redemption price equal to the purchase price of those shares of common stock. At each reporting period, the allocation between general partner capital and limited partner capital is adjusted to account for the change in the respective percentage ownership of the underlying capital of the Operating Partnership. Holders of the Class A OP Units may require MAA to redeem their Class A OP Units, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per Class A OP Unit equal, in general, to the average closing price of MAA's common stock on the New York Stock Exchange over a specified period prior to the redemption date) or by delivering one share of MAA common stock (subject to adjustment under specified circumstances) for each Class A OP Unit so redeemed.

At March 31, 2014, a total of 4,208,526 Class A OP Units were outstanding and redeemable for 4,208,526 shares of MAA common stock or approximately $287,316,070, based on the closing price of MAA’s common stock on March 31, 2014 of $68.27 per share, at MAA’s option. At March 31, 2013, a total of 1,707,660 Class A OP Units were outstanding and redeemable for 1,707,660 shares of MAA common stock or approximately $117,931,000, based on the closing price of MAA’s common stock on March 31, 2013 of $69.06 per share, at MAA’s option.

The Operating Partnership pays the same per unit distribution in respect to the OP Units as the per share dividend MAA pays in respect to its common and preferred stock.

Notes Payable

Borrowings

On March 31, 2014 and December 31, 2013, we had total indebtedness of approximately $3.46 billion and $3.47 billion, respectively. Our indebtedness as of March 31, 2014 consisted of both conventional and tax exempt debt. Borrowings were made through individual property mortgages as well as company-wide credit facilities. We utilize both secured and unsecured debt.

On August 7, 2013, our Operating Partnership entered into a $500 million unsecured revolving credit facility agreement with KeyBank National Association and thirteen other banks. This agreement amends our Operating Partnership's previous unsecured credit facility with KeyBank. Interest is paid using an investment grade pricing grid using LIBOR plus a spread of 0.90% to 1.70%. As of March 31, 2014, we had no borrowings under this facility.

On October 16, 2013, MAALP issued $350 million in aggregate principal amount of notes, maturing on October 15, 2023 with an interest rate of 4.3% per annum (the "2023 Notes"). The purchase price paid by the initial purchasers was 99.047% of the principal amount. The 2023 Notes are general unsecured senior obligations of MAALP and rank equally in right of payment with all other senior unsecured indebtedness of MAALP. Interest on the 2023 Notes is payable on April 15 and October 15 of each year, beginning on April 15, 2014. The net proceeds from the offering after deducting the original issue discount of approximately $3.3 million and underwriting commissions and expenses of approximately $2.3 million was approximately $344.4 million. The 2023 Notes have been reflected net of discount in the consolidated balance sheet. The Company entered into three forward swaps totaling $150 million, which resulted in a total effective interest rate of 4.15%.

On December 13, 2013, MAALP completed a series of exchange offers (the “Exchange Offers”) pursuant to which it exchanged $154,235,000 aggregate principal amount of 6.25% Senior Notes due 2014, $169,161,000 aggregate principal amount of 5.50% Senior Notes due 2015 and $68,130,000 aggregate principal amount of 6.05% Senior Notes due 2016 (collectively, the “Existing Notes”) issued by Colonial Realty Limited Partnership, a Delaware limited partnership and wholly owned subsidiary of MAALP, for $154,235,000 aggregate principal amount of MAALP’s new 6.25% Senior Notes due 2014 (the “2014 Notes”), $169,112,000 aggregate principal amount of MAALP’s new 5.50% Senior Notes due 2015 (the “2015 Notes”) and $68,130,000 aggregate principal amount of MAALP’s new 6.05% Senior Notes due 2016 (the “2016 Notes” and together with the 2014 Notes and the 2015 Notes, the “Exchange Notes”), plus approximately $975,000 in cash.

The Exchange Notes are senior unsecured obligations of MAALP and will rank equally in right of payment with all of MAALP’s other existing and future senior unsecured indebtedness. Interest on the 2014 Notes will accrue from, and including, December 15, 2013 and will be payable on June 15, 2014, which will also be the maturity date for the 2014 Notes. Interest on the 2015 Notes will accrue from, and including, October 1, 2013 and will be payable semiannually on April 1 and October 1 of each year, beginning on April 1, 2014. Interest on the 2016 Notes accrued from, and including, September 1, 2013 and was paid on March 1, 2014. Interest payments will be payable semiannually on March 1 and September 1 of each year, beginning on March 1, 2014. In certain circumstances described below MAALP may be required to pay additional interest on the Exchange Notes.

The Indenture under which the 2023 notes were issued and the Indentures contain certain covenants that, among other things, limit the ability of MAALP and its subsidiaries to incur secured and unsecured indebtedness if not in pro forma compliance with the following negative covenants: (1) total leverage not to exceed 60% of adjusted total assets, (2) secured leverage not to exceed 40% of adjusted total assets and (3) a fixed charge coverage ratio of at least 1.50 to 1. In addition, MAALP is required to maintain at all times unencumbered consolidated total assets of not less than 150% of the aggregate principal amount of its outstanding unsecured debt. At March 31, 2014, MAALP was in compliance with each of these financial covenants.

All of the Existing Notes tendered into the Exchange Offers were cancelled in connection with the settlement of the Exchange Offers. In connection with the issuance and sale of the Exchange Notes, MAALP also entered into three separate registration rights agreements, each dated as of December 13, 2013, and each with J.P. Morgan Securities LLC, the dealer manager in the Exchange Offers (the “Registration Rights Agreements”). Under the Registration Rights Agreements, MAALP agreed to use commercially reasonable efforts to complete exchange offers registered under the Securities Act pursuant to which MAALP will offer to issue new exchange notes containing terms substantially similar in all material respects to the Exchange Notes (except that the exchange notes will not contain terms with respect to transfer restrictions or any increase in annual interest rate) in exchange for the Exchange Notes. MAALP also agreed, if it determines that a registered exchange offer is not available or specified other circumstances occur, to use commercially reasonable efforts to file and have become effective a shelf registration statement relating to resales of the Exchange Notes. MAALP will be obligated to pay additional interest of up to 0.50% per annum on the Exchange Notes if it does not complete the exchange offers within 270 days after the issue date of the Exchange Notes and in other specified circumstances.

As of March 31, 2014, approximately 18% of our outstanding debt was borrowed through secured credit facility relationships with Prudential Mortgage Capital, which are credit enhanced by the Federal National Mortgage Association, or FNMA, and Financial Federal, which are credit enhanced by Federal Home Loan Mortgage Corporation, or Freddie Mac.

We utilize interest rate swaps and interest rate caps to help manage our current and future interest rate risk and entered into 14 interest rate swaps and 7 interest rate caps as of March 31, 2014, representing notional amounts totaling $717.0 million and $180.0 million, respectively. We also held 15 non-designated interest rate caps with notional amounts totaling $134.3 million as of March 31, 2014.

The following table summarizes our outstanding debt structure as of March 31, 2014 (dollars in thousands):

Fair Value Disclosure of Financial Instruments

Notes To Financial Statements [Abstract]

Fair Value Disclosure of Financial Instruments

 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.

On January 1, 2008, we adopted Financial Accounting Standards 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 March 31, 2014 and December 31, 2013, totaled $2.30 billion and $2.29 billion, respectively, and had estimated fair values of $2.33 billion and $2.30 billion (excluding prepayment penalties), respectively, as of March 31, 2014 and December 31, 2013. The carrying value of variable rate notes payable (excluding the effect of interest rate swap and cap agreements) at March 31, 2014 and December 31, 2013, totaled $1.16 billion and $1.18 billion, respectively, and had estimated fair values of $1.07 billion and $1.12 billion (excluding prepayment penalties), respectively, as of March 31, 2014 and December 31, 2013. 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 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 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.

Currently, we use interest rate swaps and interest rate caps (options)to manage our interest raterisk. 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.

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 March 31, 2014 and December 31, 2013 were classified as Level 2 of the fair value hierarchy.

The table below presents our assets and liabilities measured at fair value on a recurring basis as of March 31, 2014 and December 31, 2013, aggregated by the level in the fair value hierarchy within which those measurements fall.

Segment Information

Segment Information

As of March 31, 2014, we owned or had an ownership interest in 271 multifamily apartment communities in 14 different states from which we derived all significant sources of earnings and operating cash flows. Senior management evaluates performance and determines resource allocations by reviewing apartment communities individually and in the following reportable operating segments:

• Large market same store communities are generally communities:

◦ in markets with a population of at least 1 million and at least 1% of the total public multifamily REIT units; and

◦ that we have owned and have been stabilized for at least a full 12 months and have not been classified as held for sale.

• 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 in markets with a population of less than 1 million; and

◦ that we have owned and have been stabilized for at least a full 12 months and have not been classified as held for sale.

• Non same store communities and other includes recent acquisitions, communities in development or lease-up and communities that have been identified for disposition. Also included in non same store communities are non multifamily activities, which represent less than 1% of our portfolio.

On the first day of each calendar year, we determine the composition of our same store operating segments for that year as well as adjusting 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 net operating income, or NOI, a non-GAAP financial measure, 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.

Revenues and NOI for each reportable segment for the three-month periods ended March 31, 2014 and 2013 were as follows (dollars in thousands):

Derivatives and Hedging Activities [Abstract]

Derivatives, Methods of Accounting, Derivatives Not Designated or Qualifying as Hedges [Policy Text Block]

Derivatives not designated as hedges are not speculative and are used to manage the Company's exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements of FASB ASC 815, Derivatives and Hedging. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings and resulted in a loss of $69,000 for the three months ended March 31, 2014 and a loss of $13,000 for the three months ended March 31, 2013.

Earnings Per Common Share of MAA [Abstract]

Earnings Per Share [Text Block]

Earnings per Common Share of MAA

Basic earnings per share is computed by dividing net income attributable to 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.  Operating partnership units are included in dilutive earnings per share calculations when they are dilutive to earnings per share. For the three months ended March 31, 2014 and 2013, MAA's basic earnings per share is computed using the two-class method, and our diluted earnings per share is computed using the more dilutive of the treasury stock method or two-class method:

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 units outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends 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 unit computations for the three months ended March 31, 2014 and 2013 is presented below:

Notes To Financial Statements [Abstract]

Discontinued Operations

Discontinued Operations

In April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. We adopted ASU 2014-08 during the period ending March 31, 2014. Due to the early adoption of ASU 2014-08, we did not classify Brookwood Mall, which was sold on March 30, 2014, as a discontinued operation.

Willow Creek, one of the properties that we sold during the three months ended March 31, 2014, as well as the eight properties sold by us during 2013, have been classified as discontinued operations in the Consolidated Statements of Operations. One additional property, Colonial Promenade Nord du Lac, that was classified as held for sale during the first quarter of 2014 was classified as a discontinued operation. Willow Creek and Colonial Promenade Nord du Lac are included in discontinued operations because they were shown in discontinued operations as of December 31, 2013, our latest fiscal year, and thus are not subject to ASU 2014-08.

The following table lists the communities classified as discontinued operations for the three months ended March 31, 2014:

Community	Units/Sq. Ft.	Date Sold	Location	Operating Segment
Willow Creek	285	January 15, 2014	Columbus, Georgia	Secondary market same store
Colonial Promenade Nord du Lac	195,536	Held for Sale	New Orleans, Louisiana	Non-same store and other
